Rubber roller is a roller shaped product with metal or other materials as the core and rubber as the cover. What is the reason for its grooving during use? Here is the editor's summary:
If the elasticity of the rubber roller is too poor, there is a possibility of slotting, but the probability of a new rubber roller is very small. In addition to improper selection of rubber rollers, the main reasons are as follows: firstly, improper operation can cause damage to the rubber rollers due to the entanglement of fine yarn during the splicing or replacement of coarse yarn; The second reason is that the quality of the ring and the steel wire ring is poor or the fit is unreasonable, resulting in the flying ring sticking to the rubber roller and causing damage to the rubber roller; Thirdly, the roller was not cleaned in a timely manner, and the adhesive impurities on the roller caused improper glue rollers; The fourth issue is improper craftsmanship, which causes sharp fluctuations in tension during critical processes, resulting in rubber roller strains.
The correct rubber roller bearing usually includes appropriate tightness between the roller neck and the bearing. Nowadays, in order to save costs, many users often install their own bearings. Originally, there were some small accessories between the shaft head and bearings of some rubber rollers, which were used to maintain the dynamic balance of the rubber rollers and better demonstrate their balance quality. If the quality of printed products is affected by problems with rubber roller bearings, some of them will suffer minimal losses.
Rubber rollers must be carefully cleaned during daily cleaning, otherwise the surface, pigment, and resin of the rollers are easily oxidized to form a smooth and hard film, causing surface vitrification and affecting ink transfer.
