AI Technical Summary

Technical Problem

During the cooling process, the PVC film may not make good contact with the cooling roller due to different thicknesses, and may not be able to stick tightly to the surface of the cooling roller, thus affecting the cooling effect.

Method used

A cooling mechanism was designed, in which a cylinder pushes a slide to drive a traction roller to slide, and a motor adjusts the position of the traction roller to make it in close contact with the cooling roller. Combined with an anti-slip sleeve, friction is increased to adapt to the unevenness of the membrane surface.

Benefits of technology

This effectively avoids excessive spacing between the traction roller and the cooling roller, ensuring that the PVC film adheres tightly to the cooling roller, improving the cooling effect, and reducing film damage.
