First, the conveyor belt will become longer after using it for a period of time.
The conveyor belt will elongate during use. Some of them are elastically stretched, and can be restored to the original state after the external force is removed. The other part is the elongation of the shrinkage of the skeleton material. This part cannot be recovered. In the common fabric core conveyor belt, the elongation of the EP conveyor belt is relatively small, and the elongation of the NN conveyor belt is relatively large, and during use, the NN conveyor belt has a relatively large creep after the nylon fiber is subjected to the force, so the use process In the middle, the elongation ratio is increased, and because of the creep of the fiber, after the external force is removed, the amount that can be shrunk back is much smaller than the elongation.
Second, how to choose the conveyor belt:
1. Accurately explain the name and nature of the specific materials. In particular, the particle size, temperature, and availability of corrosive and special requirements such as acid and alkali. For example, the operating temperature of the heat-resistant conveyor belt should be stated.
2. Explain the specific application requirements, specifications (width, length, number of layers, thickness, etc.), especially the temperature and volume of the heat-resistant conveyor belt.
1. During transportation and storage, the conveyor belt should be kept clean and protected from direct sunlight or rain and snow to prevent contact with acids, alkalis, oils, organic solvents and other materials, and one meter away from the heating device.
2. When the conveyor belt is stored, the temperature of the warehouse should be maintained between 18-40 °C, and the relative humidity should be kept between 50-80%.
3. During storage of the conveyor belt, the product shall be placed in rolls and shall not be folded. The conveyor belt shall be turned once every quarter.
Third, what is the cause of the conveyor belt deviation?
There are mainly the following reasons for the belt to run the belt:
1. Uneven tension during the weaving process causes one side to be loose and one side tight.
2, the thickness of the two sides is not one to both sides thick and thin.
3, the tension of the flame retardant belt production process is not the same.
Fourth, the correct use of the conveyor belt:
1. Prevent the conveyor belt from starting.
2. When the conveyor belt runs off, measures should be taken to correct it in time.
3. Conveyor belts of different types and specifications should not be used together, and the joints are preferably glued.
4. The type, structure, specification and number of layers of the conveyor belt should be reasonably selected according to the conditions of use.
5, the conveyor belt running speed is generally not more than 2.5m / s, block size, large abrasive materials and the use of fixed pear discharge device should try to use low speed.
6. The relationship between the diameter of the drive roller of the roller conveyor and the layer of the conveyor belt, the matching of the drive roller, the reversing roller and the groove angle of the roller should be reasonably selected according to the design regulations of the conveyor.
7. The feeding direction should be in the running direction of the conveyor belt. In order to reduce the impact on the conveyor belt when the material falls, the chute should be adopted to reduce the material drop distance; the conveyor belt receiving section should shorten the idler spacing and use the buffer roller. In order to leak the material, the conveyor belt adopts a soft and moderate baffle plate to prevent the baffle plate from being too hard and scraping the belt surface of the conveyor belt.
8. When the conveyor is in use, if there is no roller, it should be added and repaired in time; the roller is covered by the material, causing the rotation to be ineffective, preventing the leakage from getting stuck between the roller and the tape, paying attention to the lubrication of the movable part of the conveyor belt. But not oily conveyor belts.
9. Avoid the conveyor belt being blocked by the frame, pillar or block material to prevent breakage and tearing. When the conveyor belt is partially damaged, the artificial cotton should be repaired in time to avoid expansion.
