I saw an article on the Internet that introduced a glazing machine that had been used for many years and was re-equipped with a new glazing rubber roller. During use, it was found that the rubber roller bounced so badly that it could not be used. Later, after analysis, the eccentric mass caused the rubber roller to run out. It is now organized as follows for the reference of printing machinery and printing enterprises, which may be helpful to everyone. Beware of eccentric quality when the rubber roller is selected.
What caused the newly configured rubber roller to jump? Does the rubber roller itself have quality problems? Is it because the gap between the roller neck of the rubber roller and the support sleeve is too large or is it caused by the poor cooperation between the support sleeve and the adjustable track surface? In order to solve the various questions raised above, the article introduces that the author has tested and analyzed each matching surface and matching size of the support sleeve one by one, and the rubber roller is also placed on the lathe with a dial gauge to measure the amount of circular runout and multiple The diameter of the part is shown to be normal. So some people thought of putting the old scrap rubber roller on the glazing machine and running it again to find the answer, but found that there was not much jump during the operation, and the problem disappeared again. After comparison, it seems that the new rubber roller has quality problems, but what is wrong with the new rubber roller? After careful analysis, it is finally determined that the rubber roller has serious quality eccentricity problems. If the quality eccentricity of the rubber roller is not eliminated when the roller is made, it will naturally be unbalanced during operation, which will cause jitter. In order to avoid the problem of quality eccentricity of the rubber roller, measures such as static balance or dynamic balance can be used to ensure that the rubber roller does not have quality eccentricity during the roller making process. The problem of rubber roller eccentricity has a serious impact on the production of the enterprise. In order to avoid it as much as possible, the most important thing is to adopt a formal production process to improve product quality.
Because the main technical parameters of the rubber roller are many, such as: hardness, tensile strength, crack strength, wear resistance, compression permanentness, reverse elasticity, aging resistance, ozone resistance, electrical conductivity, heat resistance, etc. The problem of eccentricity is easy to ignore, so users should pay attention when choosing.
