A film coating device for valve port woven bag production

Abstract

This utility model relates to the field of woven bag production technology and discloses a laminating device for valve-mouth woven bags. It includes a support platform, with fixed frames installed on both sides of the top of the support platform. A laminating roller is rotatably connected between the two fixed frames. A horizontal plate is fixedly connected above the laminating roller between the two fixed frames. A cleaning brush plate is movably connected to the bottom of the horizontal plate via a scraping mechanism. A negative pressure mechanism is provided on one side of the fixed frames. A water tank is fixedly connected to the bottom of the support platform. The scraping mechanism includes a forward and reverse motor installed on one side of the fixed frames. This allows the device to automatically scrape the outer surface of the laminating roller, eliminating the need for manual cleaning. Furthermore, during scraping, the elasticity of the retaining spring keeps the bottom of the cleaning brush plate in close contact with the surface of the laminating roller, greatly improving the scraping effect of the device.
