The correct way to use the belt conveyor

1) Check whether the tape and joints are damaged before driving, and if there is damage, repair it in time; Check whether the fixed part is loose, if there is looseness, it should be tightened in time; At the same time, it is also necessary to check whether the upper and lower rollers are damaged and fall off, and if so, they should be replaced in time. On the basis of the above inspection, add lubricating oil to the transmission drum and the reversing roller, the upper and lower rollers, and ensure that the oil volume of these components is sufficient and the lubrication is good, you can send a contact bell signal to the other party (especially the contact bell signal must be sent when the longer belt conveyor is running), and wait for the other party to drive after the force, and then no load test, the time of no load test should generally be 1-2h, but the small should be less than the entire belt length to run a cycle; During the test, the belt should not deviate, the driving device should run smoothly, and there should be no undue friction between the moving parts, the fixed cover and the blanking port. After the test run is normal, it can be loaded.

2) Loading to the belt conveyor, one should be evenly fed, the other should prevent deflection or overload, pay attention to whether the blanking position is in the center of the belt cross-section, if not, it should be adjusted in time.

3) When the conveyor belt is found to be misaligned, it should be adjusted in time to prevent the blanking and tearing of the conveyor belt. The method of adjusting the deviation is:

1) If the conveyor belt deviates from that side on the drum, pull the bearing seat on that side;

2) When the conveyor belt deviates on the roller, which side deviates, the several groups of rollers in the deviation part are tilted, and the direction of the deviation is to move them a little in the direction of the conveyor belt.

4) The belt conveyor should be avoided as much as possible to start at full load to prevent the motor from burning out.

5) When there is no material, the belt conveyor is not allowed to run idling for a long time.

6) Strictly prevent all metal objects from being loaded on the conveyor belt, which will cause blockage of the warehouse or break the conveyor belt.

7) Prevent the conveyor belt from being contaminated with a lot of grease or hanging a lot of ice and snow, which will make the conveyor belt slip or deviate.

8) It is not allowed to pull the conveyor belt too tightly or excessively loosen and sag (the maximum number of sagging should be less than 25mm).

9) When multiple conveyors are connected in series, each conveyor should be started in sequence from the unloading end first, and the shutdown sequence is opposite to that when starting.

10) When parking normally, the materials must be unloaded before driving.

11) In case of the following situations, emergency stop should be made:

1) When the conveyor belt is about to tear or has been broken;

2) When a large piece of material falls on the conveyor belt or the conveyor belt is jammed;

3) When the temperature of the motor or bearing is very high or has emitted a burning smell and smoke;

4) When personal safety is endangered;

5) In the tandem belt conveyor unit, when one of them fails.

Belt conveyor is an important conveyor in a variety of conveyors, and the mechanical friction and continuity of the conveyed materials work together to complete its own operation.

From the start to the end is the realization of the mechanical workflow. It is capable of conveying bulk materials as well as a wide variety of finished products. Of course, simple material transportation is only one of them, and the other is one of the hubs for completing different systems in the industry, so as to achieve a complete assembly line operation.

The working principle of the retractable belt conveyor is the same as that of the ordinary belt conveyor, which is a continuous transportation equipment with the belt as the traction carrier, but the belt storage device and the retracting and unwinding belt device are added, when the swimming trolley moves to one end of the tail, the belt enters the belt storage device, and the tail retracts; Otherwise, the tail of the machine is extended, so that the conveyor has a retractable performance. The reason is that the tension of the conveyor belt is low or there is material or water sticking to the surface of the drive pulley.

The screw should be tightened to increase the tension. Clean the drive drum and increase the cleaning force of the empty section cleaner. The reason for the deviation of the conveyor belt at both ends is that the assembly position of the drum is deviated, and the screw of the tensioning device on the side of the deviation should be tightened to adjust the position of the reversing roller.

Adjust the position of the drive drum by adjusting the bearing housing. The reason why the conveyor belt deviates in the middle is that the roller is not installed in the right position. Check whether the installation position of each roller is perpendicular to the conveyor belt, otherwise loosen the installation bolt to adjust the position of the roller.

After the adjustment is completed, tighten the bolts. In addition, a failure to place the inlet at the center of the belt can also cause mistracking, and the feed situation should be improved.

The packing density of the material and the packing angle of the material can be used to determine the bandwidth.

1.According to its own transportation volume to select the corresponding belt width, the machine in the process of transporting materials, to keep the belt conveyor continuous in its load range.

2.Usually do a good job in the maintenance of the belt, do a good job in the maintenance of the belt conveyor, and improve the operation efficiency of the belt conveyor. The overhaul and maintenance of the belt conveyor is mainly carried out for the belt conveyor cleaner, the belt itself, the power unit and the electrical protection device.

1) The belt conveyor cleaner should be checked and cleaned regularly, pay attention to whether there are any materials left around when transporting goods, and at the same time, the cleaner presses too tightly on the surface of the belt or roller or the gap is too large, which can easily cause belt damage or reduce the cleaning effect.

2) For the belt itself in the transportation of the material uniformly, properly placed on the belt, uneven placement will lead to the belt in the process of operation deviation, thus wear to the belt, belt deviation and abnormal wear is the main reason for the shortening of the belt life, so the use effect is not good.

3) The maintenance of the power unit requires the mechanical and electrical maintenance personnel to frequently observe the grease lubrication and heating of these parts, and find that these equipment have oil leakage or lubricating oil penetration in the observation, and check the cause in time, and replenish the grease to the parts of oil leakage and penetration; For equipment with abnormal heating, it is necessary to stop the machine for maintenance and check the cause in time to avoid accidents.

4) Protect electrical equipment to prevent accidental damage.

At the same time, it is also necessary to improve the business quality of the operator, after all, the machine needs to be operated manually, so the operator plays a vital step.

First, the operating principle of the belt conveyor.

Belt conveyor is used in the production field of various industrial enterprises, which can not only better meet the different production process requirements of various production industries, but also has the characteristics of large conveying capacity and long transportation distance, so it is welcomed by the majority of users and friends, and has been widely used.

When a conveyor belt runs a transport operation, it relies on friction to operate the belt drive. Stone belt conveyor is a popular conveyor. Its process structure is simple and the cost is low. The components are versatile and easy to maintain; And the conveying capacity is able to meet the general conditions.

First of all, the conveyor is explained from the composition of the belt conveyor system: the belt conveyor is an important bulk material conveying and loading and unloading equipment, which can be widely used in mining, metallurgy, building materials, chemical industry, electric power, food processing and other industrial fields. Belt conveyors can be used in a large number of places such as coal mines, metal mines, iron and steel enterprises, ports, cement plants, etc.

Transportation machinery can not only complete the transportation of bulk materials, but also convey pieces of materials, depending on the place of use and working environment.

What are the conveyor belts of belt conveyors and what are their functions.

Hello dear, what are the conveyor belts of the belt conveyor, and what are the functions of each 1, heat-resistant conveyor beltThe heat-resistant conveyor belt is made of multi-layer rubber cotton canvas (polyester cotton cloth) or polyester canvas covered with high-temperature or heat-resistant rubber, and bonded together by high-temperature vulcanization, which can convey hot coke, fire mud, slag and other materials below 175, mainly used in metallurgy, construction and other industries to convey high-temperature materials such as sinter, coke, fire clay raw meal, etc. 2. Heat-resistant conveyor beltThe heat-resistant conveyor belt is made of cotton canvas, nylon canvas or polyester canvas as the belt core, and the shrouded rubber adopts the combined rubber of reverse butadiene rubber, which can be used in the environment of 40, and has the characteristics of high elasticity, impact resistance and heat resistance. 3. Acid and alkali resistant conveyor beltAcid and alkali resistant conveyor belt is actually used in the working environment in contact with acid and alkali, such as phosphate fertilizer system, sea fire salt, shrouded rubber and plastic blending and adding alkaline excellent temperament materials, which is better than neoprene acid and alkali resistant conveyor belt.

4. Oil-resistant conveyor beltOil-resistant conveyor belt cotton canvas, nylon canvas and polyester canvas are refined through calendering, molding, vulcanization and other processes, which have relatively good oil resistance, which is suitable for conveying dew oil materials and some occasions where oily and chemical solvents may appear. 5. Food conveyor belt food conveyor belt material is PVC, polyethylene, polypropylene thin, PP, plastic steel acetal, PE, nylon, PA, etc., according to the details of the food have corresponding special conveying, in addition to high tensile strength, good direct winding, light and thin toughness, etc., it also has the upper hand of oil resistance, non-toxic hygiene, clean and hygienic, easy to clean, etc., which is an ideal conveyor belt in the food operation industry.

Answer]: The height of the c-belt conveyor bracket should be so that the lowest point of the conveyor belt is not less than the ground, and the net width of the pedestrian passage on both sides of the corridor should not be small.

Therefore, the one-sided pedestrian passage should not be less than. A bridge should be set up every 50 100m along the direction of the conveyor, and the clearance height of the abutment should not be less than that. When the inclination angle of the sidewalk on the side of the belt conveyor is greater than 6°, there should be anti-skid measures; When it is greater than 12 degrees of socks, steps should be set.

The long chute is used to transport the material, and the anti-vibration blocking device should be installed.

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.

The belt of a roller conveyor is mounted on a pulley, so another belt cannot be placed on top of it. If a belt needs to be replaced, the original belt needs to be removed and a new belt installed. When disassembling and installing conveyor belts, safety needs to be taken care of to ensure that neither the operator nor the equipment will suffer hand damage or injury.

At the same time, it is necessary to operate in accordance with the requirements and operating procedures of the equipment manufacturer to ensure the normal operation and production efficiency of the equipment.
