Technical Field
[0001] This utility model relates to the field of angle mechanism technology, specifically a mechanism that adapts to the arbitrary opening and closing angles of different ovens. Background Technology
[0002] In modern industrial production, coating is a widely used and crucial technology. Coating is the process of uniformly applying a layer of material with a specific function to the surface of a substrate material, commonly found in many fields such as electronics, printing, packaging, and batteries. Currently, there are numerous coating ovens on the market. These ovens require cylinders and hydraulic cylinders to open and close the upper and lower chambers. However, the mechanism of these cylinders limits the opening angle of the upper chamber, making it difficult for workers to change substrates and clean the interior of the oven. This patent aims to provide a mechanism that adapts to various opening angles of the upper and lower chambers, solving the problems of limited opening angles, difficult cleaning, and limited space for substrate replacement in existing ovens.
