Material and composition
An important part of the belt roller is the rubberized drum. The utility model can effectively improve the running condition of the conveying system, protect the metal drum from being worn, prevent the belt from slipping, and make the drum and the belt run synchronously, thereby ensuring efficient and large-volume operation of the belt. The encapsulation of the drum can also effectively prevent the sliding friction between the drum and the belt, reduce the material adhesion on the surface of the drum, and reduce the deviation and wear of the belt.
Common fault and maintenance editor
Since the belt roller is made of metal, it is subjected to vibration shock and other composite forces during the production operation, which may cause the belt roller bearing position to wear and the like. For the maintenance of conveyor belt rollers, the traditional methods include surfacing, thermal spraying, brushing, etc., but there are certain drawbacks: the thermal stress generated by the repair welding high temperature can not be completely eliminated, which is easy to cause material damage, resulting in bending or breaking of the components; Brush plating is limited by the thickness of the coating and is easy to peel off. Both of the above methods use metal to repair the metal, and the "hard to hard" coordination relationship cannot be changed. Under the combined action of each force, the wear will still occur again. In the contemporary Western countries, the repair method of polymer composite materials is often used for the above problems, and the Fu Shilan technology system is widely used. It has excellent adhesion, excellent compressive strength and other comprehensive properties, and can be free from disassembly and machining. . There is no effect of repair welding thermal stress, and the repair thickness is not limited. At the same time, the metal material of the product does not have the concession, which can absorb the shock vibration of the equipment and avoid the possibility of re-wearing.
