Description

Technical Field

[0001] The utility model relates to the technical field of coating machines, and particularly relates to an anti-wrinkle device for a coating machine. Background Technique

[0002] Coating machines are mainly used in the surface coating process production of films, papers, etc. It is a machine that evenly coats liquid materials such as glue, paint, and varnish on solid surfaces. It consists of a coating head, a feeding bucket, a control panel, a support frame, etc. The material is transported to the coating head through a pump. The coating head is divided into a nozzle and a scraper. The nozzle sprays the liquid material on the substrate, and the scraper evenly coats the liquid material on the substrate.

[0003] As disclosed in a wrinkle-resistant device for a coating machine with the publication number CN217190638U, this utility model discloses a wrinkle-resistant device for a coating machine, including a base. A guide plate is fixedly connected to the top surface of the base, a support plate is fixedly connected to the top surface of the base, a top plate is fixedly connected to the bottom surface of the support plate, through holes are formed through the top surface and the bottom surface of the top plate, an electric push rod is fixedly connected to the top surface of the top plate, and the output end of the electric push rod is slidably connected to the through hole. The output end of the electric push rod is fixedly connected to a sliding plate, and the sliding plate is slidably connected to the support plate. Slide holes are formed through the top surface and the bottom surface of the sliding plate, so that the roller shaft contacts the coating material, improving the tension of the coating material. Then, the coating material is coated by the coating machine body, achieving the goal of easily preventing wrinkles from appearing in the coating material through the anti-wrinkle device, avoiding the situation where wrinkles in the coating material cause uneven coating, and avoiding the situation where uneven coating affects the coating quality, making the coating machine more convenient to use.

[0004] In the above patent, mainly by pushing the moving plate downward, the roller shaft contacts the coating material. While the contact area between the roller shaft and the coating material increases, the contact area between the moving plate and the coating material also increases synchronously. As a result, the friction force between the two also increases accordingly, making the resistance of the coating material during transmission larger, which will affect the surface of the coating material and the product quality. Moreover, the increase in friction force will directly lead to a decrease in the transmission efficiency and slow down the transmission speed. Content of the Utility Model
