How is the conveyor belt installed correctly, and the installation steps of the belt conveyor?

Whether it is a new conveyor belt or an old conveyor belt, it needs to be installed on the conveyor before it can be used, so how is the conveyor belt installed on the conveyor? And how do you replace the old conveyor belt? Let me give you a brief introduction to the conveyor belt replacement method for conveyor belt repair.

Conveyor belt installation precautions.

1. Pay attention to the working rubber surface and non-working rubber surface of the conveyor belt, and the working rubber side is facing outward. (The working surface is the thicker side of the mask).

2. When attaching the new conveyor belt to the old conveyor belt, pay attention to the parallel of the new and old conveyor belts to prevent the conveyor belt from deviating.

3. Arrange personnel to guard in sections to prevent the conveyor belt from scratching and scratching, and pay special attention to the belt passing through the roller and the discharge port.

How to install a ring conveyor belt.

The annular conveyor belt is a conveyor belt that has been spliced, and this conveyor belt is more troublesome to install or replace, and it is rarely used now. The specific method is to install the idler under the belt first, then spread the belt to the conveyor, install the transmission roller, then install the upper bracket roller, and finally install the reversing roller. This is more suitable for the initial installation of conveyors.

Lifting and replacing method above the conveyor.

This method is to hoist the conveyor belt above the conveyor, use the conveyor electric roller to rotate, install the belt on the conveyor, this method is more labor-saving, and whether it is the new conveyor belt installation, or the old conveyor belt can be replaced, the specific method is as follows.

Conveyor belt replacement method in the tail.

The conveyor belt that needs to be replaced is hoisted to the tail of the conveyor belt, the new belt is attached to the old belt, and the new belt is worn to the conveyor by using the belt to rotate and drive. This method is also suitable for replacing old and new belts.

Replace the belt method under the counterweight.

Replace the conveyor belt under the conveyor counterweight, connect the old and new belts together, and use the roller rotation to replace the belt. This method is more labor-saving and is the one I use most often, but the disadvantage is that it is more laborious to connect the new belt joints. There is also a way to attach the new belt to the old belt and replace it.

The above describes some of the most common ways to replace a conveyor belt, but how exactly do you replace a conveyor belt? This is a test of how a mature conveyor belt maintenance personnel can flexibly use it according to the site situation.

Conveyor belt installation is divided into open installation and non-opening installation, and generally the non-opening installation needs to be disassembled, which is relatively troublesome and less adopted.

Belt conveyor is the abbreviation of belt conveyor, belt conveyor uses the continuous or intermittent movement of the conveyor belt to convey a variety of light and heavy items, not only can transport a variety of bulk materials, but also can transport a variety of cartons, packaging bags and other single pieces of small weight of goods, a wide range of uses.

The specific installation sequence of the belt conveyor is as follows: preparation before installation - measurement and pay-off, determine the installation position and angle of the belt conveyor - acceptance of the roadway foundation - transportation of equipment such as machine head, tensioning equipment, intermediate bracket, tail - machine head installation and alignment - installation and alignment of tensioning device - installation of middle bracket - tail installation - belt laying, connection - debugging - trial operation.

The belt conveyor is mainly composed of two end pulleys and a closed conveyor belt on which it is tightly sleeved. The pulley that drives the conveyor belt to rotate is called the drive pulley (transmission pulley);

The other pulley that only changes the direction of movement of the conveyor belt is called the reversing pulley. The drive pulley is driven by an electric motor through a reducer, and the conveyor belt is dragged by the friction between the drive pulley and the conveyor belt. The drive drum is generally installed at the discharge end to increase traction and facilitate dragging.

The material is fed by the feeding end, falls on the rotating conveyor belt, and is transported to the unloading end for discharge by the friction of the conveyor belt.

The main feature of the belt conveyor is that the fuselage can be easily telescopic, equipped with a belt storage bin, the tail can be elongated or shortened with the advancement of the coal mining face, the structure is compact, the foundation can be set up, and it is laid directly on the roadway floor, the frame is lightweight, and the disassembly and assembly are very convenient.

When the conveying capacity and transport distance are large, intermediate drives can be equipped to meet the requirements. According to the requirements of the conveying process, it can be conveyed by a single machine, or it can be combined with a horizontal or inclined transportation system by multiple units to convey materials.

Belt conveyor is widely used in metallurgy, coal, transportation, hydropower, chemical industry and other departments, because it has the advantages of large conveying capacity, simple structure, convenient maintenance, low cost and strong versatility.

(1) When adjusting the tensioning mechanism method of the belt operation, if it deviates to the same side in the case of no load and heavy load, it means that the tightness of both sides of the belt is different, and the screw or counterweight of the tensioning mechanism should be adjusted according to the law of "running tight or not loose"; If the tape deviates from left to right and there is no fixed direction, it means that the tape is loose and the tensioning mechanism should be adjusted.

2) Adjust the drum method If the tape deviates at the drum, it means that the installation of the drum is not level, the drum is axially channeled, or one end of the drum is in the front and the other end is in the back. At this time, the levelness and parallelism of the drum should be corrected. 8 p2 f; s.

3) Adjust the roller support (or frame) methodIf the belt always deviates to one side when it is not loaded, the roller support on the deviated side should be moved forward by 1-2cm along the running direction of the belt, or the roller support (or frame) on the other side should be appropriately heightened. +c8 d# t/ a) g$ ~# x

4) If there is material stuck to the part of the roller and roller, the diameter of the place will increase, and the belt tension of the conveying roller will increase, resulting in deviation. The adhered materials should be cleaned up in time. ,e0 |9 l.

5) Adjust the gravity method, if the tape does not deviate when it is not loaded, but always deviates to one side when it is heavy, it means that the tape has been eccentric. The position of the receiving hopper or tape conveyor should be adjusted so that the tape is evenly loaded to prevent it from mistracking.

6) Adjust the tape method: If the edge of the tape is seriously worn or the tape seam is not parallel, the tension on both sides of the tape will be inconsistent. The tape should be trimmed or replaced. 8 y; s( h% f; b" m# z+ f

7) If two sets of self-aligning idlers (flat rollers or slot rollers) are installed on the conveyor, the deviation of the belt can be automatically corrected. For example, when the belt deviation is rubbed against a small roller on one side, the bracket on that side should be moved forward along the running direction of the tape, and the other side should move backward relatively, and the tape will move towards the side of the roller that moves backward until it returns to the normal position.

8) Installation of limiting roller method: If the belt always deviates to one side, the limiting vertical roller can be installed on the frame on the deviation side; In this way, on the one hand, the tape can be forced to reset, and on the other hand, the vertical roller can reduce the tension of the tape on the deviation side, so that the tape can move to the other side. h1 z" t. f2 g1 u

9) Install an automatic deviation correction device on the conveyor to prevent the belt from deviating. Closed parameter c.

The adjustment of the drive drum and the reversing drum is an important part of the belt deviation adjustment. Because a belt conveyor has at least 2 to 5 rollers, all rollers must be installed perpendicular to the centerline of the length of the belt conveyor. The correction method is which side the belt deviates to and which side is tightened. As shown in the picture on the left, the belt is adjusted repeatedly until it is adjusted to the ideal position. It is best to install accurately before adjusting the drive or reversing the drum.

its location. 2. Adjust the position of the roller group: the deviation correction method is which side the belt deviates to, and the roller on that side moves forward along the running direction of the belt, or the other side moves back. As shown in the figure on the left, it is characterized by a small degree of belt correction and frequent dynamic adjustment.

3. Adjust the blanking position at the ** point: the deviation of the material in the belt groove will cause deviation. The adjustment method is to adjust the material to the middle of the belt bearing groove as much as possible. It is characterized by dynamic transformation of materials at all times, and it is difficult to adjust.

The conveyor belt is installed like this.

Put on the flexible shaft on the conveyor belt take-up core, and put the belt coil on the rack, and pay attention to the direction of the upper and lower cover glue before putting it on the shelf.

In the workplace that is not suitable for shelves, the conveyor belt can be rolled away, and the conveyor belt at the folding place has a large enough curvature radius to prevent damage to the conveyor belt, and it is forbidden to place heavy objects on the conveyor belt at the folding place.

If the belt is being replaced, the new belt can be connected to the old belt, and the belt can be removed at the same time as the new belt is installed.

For the horizontal running conveyor, the old conveyor can be cut off at any point, and the conveyor running in the inclined direction needs to be selected to prevent the sliding out of control caused by its own weight.

After the position of the new belt is placed on the conveyor, one end of the belt is fixed with a clamp, and then connected with the rope of the bypass roller and the pulley, and the conveyor belt is balanced on the conveyor through the traction device, and the conveyor belt and the frame should be prevented from squeezing each other when pulling.

Fix one end of the belt to the conveyor frame with a clamp, and the other end is pulled tight by a pulley until the belt does not sag significantly on the return roller.

Fix the tensioning device 100-150mm from the starting point.

There are several ways to do this:

1. Mechanical joint method.

Generally, it refers to the use of belt buckle joints, which are convenient and convenient and economical, but the efficiency of the joints is low, easy to be damaged, and has a certain impact on the service life of conveyor belt products. In PVC and PVG full-core flame retardant and antistatic conveyor belt joints, this joint method is generally used for products below grade 8 belts.

2. Hot melt method.

The two ends of the conveyor belt are layered and then spliced together and simply fixed with a heat gun. Put the assembled conveyor belt on the hot melt equipment to heat and pressurize for hot melting, the temperature is about 140, and after the cloth layer reaches the holding time, stop heating and let it cool naturally to room temperature, and remove the conveyor belt can be used normally.

3. Cold adhesive method.

According to the requirements, the conveyor belt is cut and peeled into a stepped hair, the surface is cleaned with propylene copper, and the special glue for the two-component conveyor belt is mixed evenly on the cutting and stripping layer after mixing according to the mixing ratio on the manual, and both sides should be coated, and the flat head hammer is evenly smashed by hand; Flatten the joints with glue, equalize them with pressure, and use them after 24 hours.

All conveyor belts must be connected into a ring before they can be used, so the quality of the conveyor belt splice directly affects the service life of the conveyor belt and whether the conveyor line can run smoothly and smoothly. Generally, the common methods of conveyor belt joints include mechanical joints, cold bonded joints, hot vulcanized joints, etc. Practice has proven to be the most ideal method to ensure high joint efficiency, but also very stable, long joint life, and easy to master.

However, there are disadvantages such as process trouble, high cost, and long joint time.

The longitudinal tearing elongation of the full thickness is not less than 10%, and the elongation of the longitudinal reference force of the full thickness is not greater than the technical specification of the joint.

The joint can be connected by plate vulcanization to ensure the pressure and temperature required for vulcanization or melting, the structure of the joint has a variety of forms, which depends on the structure of the belt, for the heat-resistant, cold-resistant, oil-resistant, acid-resistant, alkali-resistant flame retardant and other special requirements of the conveyor belt, attention should be paid to the corresponding bonding method, otherwise the joint connection force can not achieve the expected effect, and finally the environment of the joint needs to pay attention to be absolutely dry, clean, no dust, no exposure, for wet places, water vapor must be removed repeatedly, If necessary, protective facilities can be erected to meet the joint requirements.

You can use special joint products: righteous joints, produced by Qingdao Hikang Huatuo rubber.

When installing the roller conveyor conveyor belt (roller table), a starting device that can be locked should be used. In addition, in order to prevent sudden accidents, the conveyor should also be equipped with a button to start or stop on the spot. In order to prevent the conveyor belt from being torn longitudinally for some reason, Hefei Sainel plate chain conveyor recommends that when the conveyor length exceeds 30m, install a stop button at a certain distance at every certain interval.

After installation, the start of the conveyor should be carried out under no-load conditions.

The maintenance of the roller conveyor is for better use of the conveyor. Therefore, we must find and eliminate possible faults of the conveyor in time. Hefei Sinaire believes that operators must observe the working condition of the conveyor at any time, and deal with abnormalities immediately.

In addition, mechanical workers should make regular rounds and inspect any situations or components that need attention from the plate chain conveyor. For example, an idler of a roller conveyor, although it is not very important, if it is conveyed at high speed, its shell may quickly wear through its shell, and a knife edge appears, which may damage the most expensive conveyor belt. Therefore, we must pay attention to the training of operators and maintenance personnel on the operation and maintenance knowledge of conveyor belts.

Conveyor belt installation method:

1.Wash the belt and pulley, wipe with a cloth dipped in some non-volatile liquid, do not soak in detergent or use detergent to wipe the belt. The saddle strap must be kept dry before installation.

2.In the case of unsuitable replacement, the conveyor belt can be opened first, and let it have a large enough bending radius to prevent damage to the belt, and it should not be folded to place heavy objects.

3.When removing and installing the conveyor belt, the center distance between the two pulleys should be adjusted to avoid hard pry damage to the belt or equipment. Once the belt is covered, the center distance between the two wheels should be adjusted to the correct position.

The belt should have proper tightness. At this point, one end of the conveyor belt can be fixed to the conveyor frame with a clamp, and the other end can be tightened with a pulley until the conveyor belt does not sag significantly on the return roller.

4.If the old belt is replaced, the new belt can be connected with the old belt, and the unloading and installation of the new belt are carried out at the same time. If it's a set of belts, the damage will need to be replaced in a group, so don't mix old and new.

5.For horizontal conveyors, it can be cut off at any point, and the cutting point is required to be selected in the direction of inclination of the conveyor to prevent loss of control due to weight slippage.

6.The belt must be properly seated in the wheel groove and the outer edge of the belt should be flush with the rim. The two pulleys should keep their axes parallel and the symmetry planes of the two pulleys should coincide.

7.Accidents can also be prevented by installing a protective cover to prevent lubricating oil, cutting fluid or other foreign objects from spilling on the belt.

8.Tighten the mounting bolts of the motor to correct the torque. Make sure all transmission parts are tightened.

It is important to note that special attention should be paid to the performance of the conveyor belt when starting the unit. If you notice any unusual vibration or noise, turn off the machine immediately and check the bearings and motor to confirm that there are no problems with the installation.
