Vacuum coating technology can greatly improve the conductivity, antioxidant performance, anti-aging function, etc. of the product, thereby increasing the service life of the product and improving the quality of the product. At present, the process of vacuum coating has gradually spread to various industrial fields. Among them, vacuum winding coating equipment is mainly dedicated to the production of large-scale mechanical equipment for metallized films on the surfaces of some processable objects. However, the most commonly used heating method in the vacuum evaporation coating machine currently used is electric heating, and the coating material is evaporated by a resistively heated crucible. Due to the requirements for product quality, it is usually necessary to ensure that the evaporation process always produces as little splash as possible, and impurities in the cavity are an important cause of evaporation splashes. Therefore, in the vacuum coating machine, it is usually necessary to use a cover to cover the crucible after stopping or opening the hatch to prevent dust from falling into the crucible.

[0003] At present, the vacuum coating machine in the prior art usually adopts a horizontal telescopic cover (such as CN115323330A), that is, a power part is set on the side of the equipment to push the cover to move horizontally, and a base needs to be set in the equipment to support the cover. The base will occupy the internal space of the equipment, thereby affecting the size of the crucible. Utility Model Content
