Description

Technical Field

[0002] A coating machine is a device that applies coatings, such as paste polymers, molten polymers, or solutions, to the surface of various substrates, including paper, fabrics, leather, and metal foil, at a uniform thickness. Its basic principle is to transfer the coating onto the substrate through a coating head and utilize various control methods to ensure uniform coating distribution and a thickness that meets set requirements.

[0003] Existing coating machines typically use a single roller for tension control. After the roller is reassembled, it is not easy to quickly restore a stable coating state, which affects the uniformity of the coating. Moreover, the replacement of the roller is an unavoidable operation, which usually requires a long downtime, thus reducing the production efficiency of the equipment. Utility Model Content
