AI Technical Summary
The existing guide roller device cannot clean the surface of the plastic film, causing the plastic film to be squeezed with impurities during the winding process, affecting the film quality. After long-term use, the guide roller surface is covered with impurities, reducing its service life.
A guide roller for plastic film production was designed, equipped with a cleaning structure and a scraping structure. The cleaning structure drives the bumps to move by hand-tightening bolts, making the cleaning roller come into contact with the guide roller, and lightly presses and sweeps away dust and debris on the film. The scraping and sweeping structure uses a coil spring and a connecting cloth to drive the scraper, and as the guide roller rotates, the surface of the guide roller is cleaned.
It effectively removes dust and debris on the surface of the plastic film, prevents the decline of the film quality caused by the extrusion of the film and debris after winding, and extends the service life of the guide roller.
