How to maintain the roller shaft of the production line?
1. During the installation of loading and unloading rubber rollers, the coordination between the shaft head and the bearing shall ensure certain accuracy and cleanliness. It shall be handled with care and shall not collide with the shaft head and the rubber layer, so as to avoid damage, bending and damage of the roller body.
2. The rubber bearing head shall be lubricated effectively. If the lubrication is poor, it will cause the wear of rubber roller shaft head and bearing, increase the gap, and even uneven printing. At the same time, it will also cause printing bar marks due to poor conditions such as rubber roller jumping and sliding. If there is no effective lubrication during continuous operation for a long time, it will also cause heat generation of the bearing and shaft core, and cause the rubber surfaces at both ends of the rubber roller to be worn due to thermal expansion, so that the rubber surfaces at both ends will have pitted surface, glue falling and cracking.
3. The pressure between the rubber roller, the rubber roller and the printing plate shall be adjusted appropriately according to the elasticity and hardness of the rubber and its role in the printing process. Generally, a feeler gauge of o.15 ~ o.20mm (the feeler gauge shall be lubricated to avoid damaging the rubber surface) shall be used for testing, and the radial contact pressure of the rubber roller must be uniform. Otherwise, long-term operation will cause pitting, glue falling, cracking, glue opening and other phenomena on the rubber roller at the end with high pressure.
