A glazing machine that has been used for many years has been repaired and equipped with a new glazing rubber roller to be put into trial operation. As a result, the rubber roller bounces seriously and cannot be used.
What is the cause of the bounce of the rubber roller?
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 poor, and some people think that the rubber roller itself has quality defects that affect the normal operation of the rubber roller . To this end, we have tested and analyzed the matching surfaces and matching dimensions of the support sleeve one by one, and the results are normal. We also placed the rubber roller on the lathe and measured the circular runout of the rubber roller and the diameter of multiple parts with a dial indicator. The measurement results showed that the circular runout and diameter tolerance of the rubber roller were within the range of first-class products. From this point of view, it seems that there is no problem with the size of the parts and assembly of the glazing machine and this rubber roller.
So what is the reason for the bounce of the rubber roller?
We put an old rubber roller that has been worn out and scrapped on the glazing machine for trial operation. As a result, this old rubber roller runs smoothly and does not produce large jumps. Quality defects in the rubber roller itself. On this basis, we conducted an in-depth understanding and analysis, and finally determined that the main reason for this new rubber roller bounce in operation is the rubber roller quality eccentricity. If the quality eccentricity of the rubber roller is not eliminated in the production of rollers, the unbalanced force generated during operation will inevitably stimulate the bounce of the rubber roller. Adopt formal production technology and quality control, in the process of making the rubber roller, through the measures of static balance or dynamic balance to ensure that the rubber roller does not have quality eccentric defects, so that it will not be caused by imbalance in use beat.
