A PE film hot-pressing bonding device

By combining the collaborative action of the bonding pressure roller driven by an electric cylinder with the auxiliary roller, and the design of the moving plate driven by a servo motor, the shortcomings of the existing device in material thickness adjustment and winding and unwinding are solved. This achieves efficient and stable bonding of PE cover film and rapid roll change, thereby improving production efficiency and product quality.

AI Technical Summary

Technical Problem

Existing PE cover film hot pressing lamination equipment is difficult to adjust the pressure flexibly according to the material thickness, which makes thin substrates easy to deform or thick materials not bond firmly. In addition, the traditional winding roller replacement operation is cumbersome and affects production efficiency.

Method used

The bonding roller and auxiliary roller are driven by an electric cylinder to work together to dynamically adjust the bonding gap and pressure. Combined with the servo motor driving the threaded rod to move the moving plate, the take-up roller can be quickly assembled and disassembled. With the segmented temperature control of the heating plate and hot press roller and the rapid cooling of the cooler, bonding quality and production efficiency are ensured.

Benefits of technology

It achieves tight bonding of materials of different thicknesses without bubbles, shortens roll changeover time, improves production efficiency and product quality, and ensures the stability of winding and continuous production.

Abstract

This utility model discloses a PE cover film hot pressing lamination device, including a base plate, a vertical plate and a fixed plate fixedly connected to the top of the base plate, a heating box and a cooler fixedly installed between the vertical plate and the fixed plate and located at the top of the base plate, a substrate hanging plate and a PE film hanging plate fixedly connected to one side of the vertical plate, and material rollers are provided inside the substrate hanging plate and the PE film hanging plate, respectively. A through groove is opened inside the vertical plate, and guide rollers are rotatably connected to both sides of the through groove and located on one side of the vertical plate. A movable plate is slidably connected to the top of the base plate, and a displacement component is provided inside the base plate. This utility model uses an electric cylinder-driven lamination pressure roller and an auxiliary roller to work together to dynamically adjust the pressing gap and pressure, adapting to substrates and PE films of different thicknesses, ensuring tight lamination without air bubbles; combined with the segmented temperature control of the heating plate and hot pressing roller, it realizes integrated processing of softening, pressing and pre-curing, providing a uniform and stable semi-finished product for subsequent cooling and shaping.
