What is the reason for the deviation of the upper part of the PVC conveyor belt but the deviation of the lower part?
What causes the upper side of the PVC conveyor belt to deviate but the lower side to deviate?
The left and right sides of the PVC conveyor belt interact and are unrelated to each other. In general, insufficient flatness and roller level of the lower buffer roller will also cause the conveyor belt to deviate in the lower direction. Deviation in the lower direction, while normal things like this above are mostly caused by poor cleaning equipment, material stuck to the lower buffer roller, unequal load-bearing rollers, or the load-bearing support frame is tilted, and the lower roller brackets are not equal to each other. The details should be adjusted according to the actual situation. Generally speaking, the deviation in the lower direction can be corrected by improving the working conditions of the cleaning equipment, eliminating materials adhered to the rollers and buffer rollers, adjusting the lower flat buffer rollers, the lower V-shaped buffer rollers, or assembling them. The lower self-aligning roller realizes the effect of the deviation correction device. Conveyor Belt provides full tracking and after-sales maintenance services for the products it sells, and will provide you with answers to problems that arise during the application process throughout your life.
Is it easy for a long-span conveyor belt to deviate in direction?
PVC conveyor belts sometimes deviate in direction during operation. Generally speaking, it is rare for the conveyor belt to deviate due to problems with the conveyor belt itself. The directional deviation of the conveyor belt is mainly due to the conveyor. The main reasons for the conveyor belt are unequal rollers, non-vertical mounting brackets, and insensitive roller rotation, which can cause the conveyor belt to deviate in direction. For shorter conveyor belts, due to the inflexible rotation of one side of the roller and other factors, the possibility of the conveyor belt deviation is very high, and for long conveyor belts, due to the increase in the number of buffer rollers , the irreversibility of the influence on one side will also be reduced, so the direction deviation shown on the conveyor belt will be reduced. Of course, except for certain circumstances, such as when the self-aligning roller is unstable or is tilted and fixed, the surface of the roller is not cleaned enough, or environmental factors, etc., can cause the conveyor belt to deviate.
The quality of PVC conveyor belt products is solid. You can use it with confidence.
Why are PVC conveyor belt joints so easy to crack and break?
The strength of the PVC conveyor belt joint is slightly lower than that of ordinary belts. Generally, when mechanically connected, the compressive strength of the connector can only reach 40-50% of the belt strength. When the quality of the cold bonding method is relatively good, the compressive strength of the connector can reach 60-70%, while the thermal bonding head can reach 60-70%. The compressive strength can reach 80-90% (appropriate interface method, no quality hazard). Since the strength of the joint is very low, the strength of the joint will be even lower if the bonding method is incorrect, such as using a knife, damaging the next layer of cloth during grinding, excessive polishing, insufficient anchoring length, and the number of steps. Insufficient, the properties of commonly used plastics for bonded joints are not very good or have become ineffective in self-sulfurization, the galvanized steel wire rope is polished too much, the galvanized steel wire rope is rusted, etc., the compressive strength of the joint position may be affected, and it is easy to occur during use. The connector position is broken.
In addition, if the sealing glue is not used on the conveyor belt, or if the glue joints are in the wrong direction, the joints will easily crack (surface glue position).
