The following is a brief description of the correct use and maintenance of rubber rollers:
1. Newly cast rubber rollers should not be put into use immediately
Since the internal structure of the newly cast rubber roller is not stable enough, if it is put into use immediately, the service life is likely to be reduced. Therefore, the new rubber roller just out of the cylinder should be placed for a period of time to keep the rubber roller in a relatively stable state after contacting the temperature and humidity of the external environment. This can increase the toughness of the gel and improve the durability.
2. Correct storage of idle rubber rollers
After cleaning the ready-to-use rubber rollers, wrap the gel with plastic film and place it on the rubber roller rack. Don’t stack a few of them randomly or stand upright against the wall, so as to avoid undue loss of the gel. . During the transportation process of the used rubber rollers for processing and casting, please avoid throwing them away or pressing them, and keep the roller core from eccentricity and bending to ensure the normal use of the roller core.
3. The rubber roller shaft head and bearing should be kept well lubricated
We know that the accuracy of the rubber roller shaft head and bearing directly affects the effect of ink transfer and distribution. If poor lubrication causes the rubber roller shaft head, bearing wear and gap, it will inevitably lead to the disadvantage of uneven printing ink. At the same time, printing bumps may also be caused by bad conditions such as rubber jumping and slipping. Therefore, lubricating oil should be frequently added to the rubber roller shaft head and bearing to prevent the mechanical parts from wearing out and the rubber roller can be used normally to ensure the printing quality.
