the belt will be extended during use, some of which are elastic and can be restored to the original after the external force is withdrawn. the other part is the amount of elongation of the skeleton material, which can not be recovered.
1、 the conveyor belt will be longer after use for a period of time
the belt will be extended during use, some of which are elastic and can be restored to the original after the external force is withdrawn. the other part is the amount of elongation of the skeleton material, which can not be recovered. the commonly used fabric conveyor belt, ep belt elongation is relatively small, while the nn belt elongation is relatively large, but in the process of use, nn conveyor belt due to creep force of nylon fiber is relatively large, so in the process of using, the elongation ratio increased, but because of the fibers in the creep force removal after, can shrink back amount is less than the elongation.
2、 conveyor belt deviation
the main reasons for the conveyor belt are the following:
during the weaving process, the tension is uneven, causing one side to be loose and tight.
the thickness of both sides is different from one side to the other.
there are different tension in the process of producing flame retardant belt.
3、 the correct use of conveyor belt:
prevent conveyor belt load start.
conveyor belt deviation should be taken in time to correct.
the conveyor belts of different types, sizes and layers shall not be used together, and the joints shall be preferably glued.
the type, structure, specification and number of layers of ordinary conveyor belts and special conveyor belts should be rationally selected according to the service conditions.
conveyor belt running speed is generally not more than 2.5m/s, block size, wear of large materials and the use of fixed pear discharge device should be used as low speed as possible.
the relationship between the driving roller conveyor, roller diameter and the conveying belt cloth layer driving drum, drum to the supporting roller and groove angle requirements should be based on the design requirements of transport, reasonable selection.
the feeding direction along the direction of belt, in order to reduce the material falling on the conveyor belt impact should adopt the chute, reduce materials gap distance; the conveyor belt feeding section, should shorten the distance between rollers and the buffer roller for leakage of conveyor belt using adaptation block plate of moderately soft plate, so as not to file excellent, scraping conveyor belt surface.
the conveyor is in use, such as the lack of a roller, should be promptly added and repaired; roller materials were covered by rotary, prevent leakage between the drum and tape to card, pay attention to conveying lubrication with the movable part, but not the oil conveying belt.
to avoid the conveyor belt from a pillar or block block material, prevent pengpo tear, find local conveyor belt breakage, application of artificial cotton and timely repair, so as not to expand.
4、 how to buy conveyor belt?:
accurate description of the name and nature of the specific material. especially grain size, temperature, acid, alkali and other corrosive and special requirements. for example, the service temperature of heat resistant conveyor belt should be explained.
description of the specific application occasions, requirements specifications (width, length, number of layers, thickness, etc.), especially the use of heat-resistant conveyor belt temperature and traffic volume.
5, how to transport, storage, conveyor belt?
the conveyer belt should be kept clean in transportation and storage, avoid direct sunlight or rain and snow dipping, prevent contact with acid, alkali, oil, organic solvent and so on, and be away from the heating device one meter away.
storage temperature should be kept between 18-40 degrees, and relative humidity should be kept between 50- 80%.
during the storage of conveyor belt, products must be placed into a roll, not folded, turning once the conveyor belt should be quarterly.
