Description

Technical Field

[0001] This utility model belongs to the field of film coating technology, and in particular relates to a feeding device for a film coating machine. Background Technology

[0002] A laminating machine is a device used to cover the surface of various materials with a thin film, widely used in packaging, printing, electronics, automotive, and other industries. It improves the waterproof, dustproof, and UV-resistant properties of a substrate by attaching a film material to it, while also enhancing its appearance. Laminating machines are mainly divided into two types: hot laminating machines and cold laminating machines, depending on the film material used and the temperature control method. The feeding device of the laminating machine is a crucial part of ensuring the smooth operation of the production line. Its main function is to stably and smoothly feed the material to be laminated into the laminating area. Due to the lack of a guiding structure in the feeding devices of some laminating machines, material easily accumulates at the feeding port, leading to blockages or waste. Summary of the Invention
