The reason that causes the rubber roller to run beating

Some people think that the gap between the roller neck of the rubber roller and the support sleeve is too large or the cooperation between the support sleeve and the adjustable track surface is not good. Some people think that the quality defect of the rubber roller itself affects the normal operation of the rubber roller. . To this end, we have tested and analyzed the mating surfaces and mating dimensions of the support sleeve one by one, and the results are normal. We also put the rubber roller on the lathe to measure the circular runout of the rubber roller and the diameter of multiple parts. The measurement results show that the circular runout and diameter tolerance of the rubber roller are all within the first-class range. In this way, it seems that the size of the parts of the glazing machine and the size of the assembly have no problems with this rubber roller.

So what is the reason for the running beating of the rubber roller? We installed a worn out old rubber roller on the varnishing machine for trial operation. As a result, the old rubber roller ran smoothly and did not produce large jumps. This shows that the main reason for the large jump in the operation of the new rubber roller is still It lies in the quality defect of the rubber roller itself. On this basis, we conducted an in-depth understanding and analysis, and finally determined that the main reason for the beating of this new rubber roller during operation was the quality eccentricity of the rubber roller. If the quality eccentricity of the rubber roller is not eliminated in the roll making process, the unbalanced force generated during the operation will definitely arouse the beating of the rubber roller. The quenching roller adopts formal production process and quality control. During the production of the rubber roller, measures such as static balance or dynamic balance should be used to ensure that the rubber roller does not have quality eccentricity defects, so that it will not be unbalanced during use. produce jumping.
