How to avoid the sticking phenomenon of the printing rubber roller?
Adhesion of printing rollers is a common problem, which will not only affect the printing quality, but also shorten the service life of the rollers. So, how to avoid the sticking phenomenon of the printing rubber roller?
First of all, it is necessary to choose the right rubber roller. Different materials of rubber rollers will have different properties, such as wear resistance, high temperature resistance, etc. When selecting rubber rollers, it is necessary to select the appropriate rubber rollers according to the model of the printing machine, printing materials and printing processes and other factors, so as to avoid adhesion due to the mismatch of rubber roller materials.
Secondly, it is necessary to control the printing speed. If the printing speed is too fast, it will cause the temperature of the rubber roller to rise, which will accelerate the aging of the rubber roller and the phenomenon of adhesion. Therefore, according to the requirements of the printing material and the printing process, the printing speed should be reasonably controlled to avoid adhesion due to the printing speed being too fast.
Also, keep the printing press in good condition. If there is a mechanical failure or poor lubrication of the printing machine, the operation of the rubber roller will be inflexible and unstable, resulting in adhesion. Therefore, it is necessary to regularly check the mechanical parts and lubrication system of the printing machine to ensure that the printing machine is in good condition and avoid adhesion due to mechanical failure and other reasons.
Finally, pay attention to the maintenance of rubber rollers. After a period of use, the surface of the rubber roller will be stained with contaminants such as oil stains and ink residue, which will affect the operation of the rubber roller and the printing quality. Therefore, it is necessary to clean the surface of the rubber roller regularly to avoid adhesion due to contaminants.
In short, to avoid the sticking phenomenon of the printing roller, it is necessary to start from many aspects, including choosing the right rubber roller, controlling the printing speed, keeping the printing machine in good condition and paying attention to the maintenance of the rubber roller. Only in this way can we effectively extend the service life of the printing roller and improve the printing quality.
