How to use the conveyor belt, the main role of the conveyor belt?

Conveyor belt, belt conveyor is widely used in agriculture, industrial and mining enterprises and transportation industry to convey a variety of solid block and powder materials or finished items, conveyor belt can be continuous, high-efficiency, large inclination angle transportation, conveyor belt operation safety, conveyor belt is easy to use, easy maintenance, low freight, and can shorten the transportation distance, reduce project costs, save manpower and material resources. Conveyor belt, also known as conveying belt, is a rubber and fiber, metal composite products, or plastic and fabric composite products used for carrying and transporting materials in belt conveyor belts. Conveyor belts are widely used in cement, coking, metallurgy, chemical industry, steel and other industries with short conveying distance and small conveying volume.

1. Prevent the load of the conveyor belt from starting.

2. If the conveyor belt deviates, measures should be taken to correct it in time.

3. Conveyor belts of different types and specifications should not be used together, and their joints should be made of vulcanization.

4. The type, structure, specification and number of layers of the conveyor belt should be reasonably selected according to the use conditions.

5. The running speed of the conveyor belt should not be greater than that, and the materials with large blockiness and high wear and tear should be used as low as possible for the unloading device of fixed pears.

6. The relationship between the diameter of the transmission drum and the cloth layer of the conveyor belt, the matching of the transmission drum and the reversing pulley and the requirements for the groove angle of the roller should be reasonably selected according to the design regulations of the conveyor.

7. The feeding direction should follow the running direction of the conveyor belt, and a chute should be used to reduce the impact on the conveyor belt when the material falls, so as to reduce the distance of the material drop; In the receiving section of the conveyor belt, the spacing of the rollers should be shortened and the buffer roller should be used as the leakage, and the conveyor belt should be compliant with a soft and moderate baffle plate, so as to avoid the baffle plate being too hard and scratching the belt surface of the conveyor belt.

8. When the conveyor is in use, it should be added and repaired in time for the lack of rollers, and the rollers are covered by materials, resulting in ineffective rotation, so as to prevent leakage from being stuck between the roller and the belt, and pay attention to the lubrication of the moving part of the conveyor belt, but not to oil the conveyor belt.

9. Avoid the conveyor belt being blocked by frames, pillars or block materials, prevent it from breaking and tearing, and when it is found that the conveyor belt is partially damaged, it should be repaired in time with rayon to avoid expansion.

Belt definition.

Conveyor belts are also called conveyor belts.

The purpose of the conveyor belt.

Rubber, fiber, metal composite products, or plastic and fabric composite products that play the role of carrying and transporting materials in belt conveyors. Belt conveyor is widely used in agriculture, industrial and mining enterprises and transportation industry to convey a variety of solid lump and powder materials or finished items, can be continuous, high efficiency, large inclination transportation, safe operation, easy to use, easy maintenance, low freight, and can shorten the transportation distance, reduce the cost of the project, save manpower and material resources to the manufacturer has brought great convenience, people can be more convenient, more labor-saving.

Conveyor belt classification.

There are many types of conveyor belts, which are classified according to their uses: general purpose conveyor belts, flame retardant and antistatic conveyor belts, general flame retardant conveyor belts, heat-resistant conveyor belts, high-temperature resistant conveyor belts, acid-alkali resistant conveyor belts, oil-resistant conveyor belts, cold-resistant conveyor belts, etc. According to the product structure, the main ones are:

Layered conveyor belts, whole core conveyor belts, steel wire rope core conveyor belts, steel cable conveyor belts, tubular conveyor belts, pattern conveyor belts, edge conveyor belts, layer reduction conveyor belts, etc.

(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.

Method: Conveyor belt 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.

Conveyor belt cold-bonded joint method.

Conveyor belt splices.

That is, a cold-bonded adhesive is used for the joint. This joint method is more efficient than mechanical joints, and it is more economical, and it should be able to have a better joint effect, but from a practical point of view, because the process conditions are difficult to master, and the quality of the adhesive has a great impact on the joint, so it is not very stable. At present, among the more well-known adhesives in China, Shengka SK811 conveyor belt glue, Huangshi LDJ243 series and other conveyor belt glues are used in large quantities in China.

Conveyor belt hot vulcanized joint method.

Conveyor belt splices have proven to be the most ideal splice method in many years of practice, ensuring high splice efficiency, but also being very stable, with a long splice life and easy to master. However, there are disadvantages such as process trouble, high cost, and long joint time.

Conveyor belt hot vulcanized joint rubber is relatively hard Reason:

After we realize the splicing of the conveyor belt, we often find that the splice part is harder than other parts, and the process of vulcanizing and gluing the conveyor belt is actually the process of continuous cross-linking of vulcanized rubber. Since vulcanization requires heating and pressurization, and it takes a long time, the hardness of the vulcanized rubber will increase after a long period of vulcanization, so the joint part will feel stiffer than other parts.

The strength at the belt splice is lower than the strength of the normal belt body. Generally, when connected mechanically, the strength of the joint can only reach 40 50% of the strength of the belt, and when the quality of the cold glue method is relatively good, the joint strength can reach 60 70%, and the strength of the hot glue joint can reach 80 90% (the joint method is correct and there is no quality defect). Due to the low strength of the joint, if the glue joint method is incorrect, the strength of the joint will be lower, such as the knife, the next layer of cloth is injured during grinding, excessive grinding, the lap length is not enough, the number of steps is not enough, the rubber performance of the rubber joint is not good or has been self-sulfur failure, the wire rope is over-polished, the wire rope is rusty, etc., the strength of the joint part will be greatly reduced, and the joint part is easy to break when in use.

In addition, if the belt does not use sealing glue or if the glue joint is in the wrong direction, the joint is prone to cracking (top adhesive part).
