How to deal with the wear of the driving part of the roller coating machine
roller coating machine is mainly used for film, paper surface coating process production, this machine is to roll the substrate coated with a layer of specific functions of glue, paint or ink, and dry and roll up. It uses a special multi-functional coating head, which can realize various forms of surface coating. The winding and unwinding of roller coating machine are equipped with full speed automatic film connecting mechanism and PLC program tension closed-loop automatic control.
During the operation of the roller coating machine , the problem of the wear of the transmission parts often occurs, such as the abrasion of the drying cylinder shaft head and the wear of the paper roll bearing chamber. The traditional repair methods include surfacing, thermal spraying, brush plating, etc., but there are some disadvantages: surfacing will make the surface of the parts reach a very high temperature, resulting in deformation or cracks, or even fracture of the shaft in serious cases; the electroplating coating can not be too thick, and the pollution is serious, so the application is limited. The material has good adhesion and compressive strength, which can repair the abrasion of roller coating machine on site without disassembly. At the same time, because of its metal lack of yielding, it can well absorb the impact vibration of equipment and avoid secondary wear.
