Printed tape is commonly used in our usual items, What, now also many kinds of printing tape, we purchased what division should be choose? Select the tape to understand two goals:1.The conveyor belt will become longer after a period of use
The conveyor belt will stretch during use, part of which is elastic elongation, which can return to its original state after the external force is withdrawn, and the other part is the elongation of the contraction of the skeleton material. This part cannot be recovered. Among the commonly used fabric core conveyor belts, the EP conveyor belt has a relatively small elongation, while the NN conveyor belt has a relatively large elongation. In addition, during the use process, the NN conveyor belt has a larger creep after the nylon fiber is stressed. In the medium, the elongation ratio is increased, and because the fiber creeps, after the external force is withdrawn, the amount that can be contracted back is much smaller than the elongation.
2.Conveyor belt deviation
The main reasons for the deviation of the belt body are as follows:
① Uneven tension during the knitting process causes looseness and tightness.
② The thickness of both sides is not the same.
③ The tension during the production of flame retardant tapes is not the same.
3. The correct method of using the conveyor belt:
① Prevent the load of the conveyor from starting.
② Deviation of the conveyor belt should be corrected in time.
③ Conveyor belts of different types and specifications should not be connected together, and the joints should be glued together.
④ The type, structure, specifications and number of ordinary conveyor belts and special conveyor belts should be reasonably selected according to the use conditions.
⑤ The running speed of the conveyor belt should generally not be greater than 2.5m / s. Materials with large block size and high abrasion and the unloading device using fixed pear should use low speed as much as possible.
⑥ The relationship between the diameter of the driving roller of the roller conveyor and the layer of the conveyor belt, the matching of the driving roller, the redirecting roller, and the requirements for the groove angle of the supporting roller should be reasonably selected according to the design requirements of the conveyor.
⑦ The feeding direction should follow 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 distance of the material drop. If the material is leaking, the conveyor belt conforms to a soft and moderate blanking plate to prevent the blanking plate from being too hard and scratching the belt surface.
在 When the conveyor is in use, if there are missing support rollers, it should be added and repaired in time; the support rollers are covered by the material, causing the rotation to be ineffective, preventing leakage of materials between the roller and the tape. Do not oil the conveyor belt.
⑨ Prevent the conveyor belt from being blocked by racks, pillars, or block materials, and prevent tearing and tearing. When the conveyor belt is partially damaged, apply artificial cotton to repair it in time to avoid expansion.
