It is a synthetic material that is deeply loved, popular and widely used in the world today.

[0003] In the process of removing static electricity from PVC film, static electricity is often eliminated by conveying. However, in the process of transmitting the film, the static electricity elimination conveying roller sometimes clamps the film too tightly or too loosely. Tightness may damage the film, and looseness may affect the transmission efficiency. Therefore, it is necessary to always pay attention to the tightness of the static electricity elimination conveying roller and adjust it. In traditional static electricity elimination transmission rollers, the static electricity elimination transmission roller needs to be disassembled to adjust the tightness, which is troublesome to adjust.
