[0019] To make the purpose, technical scheme and effect of the present application more clear and definite, the present application will be further described in detail below with reference to the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and should not be used to limit the present application.
[0020] It should be noted that when a component is referred to as being "mounted on", "fixed on" or "disposed on" another component, it can be directly on the other component or there can be a middle component. When a component is referred to as being "connected to" another component, it can be directly connected to the other component or there can be a middle component.

[0022] The winding device, as an important component of the coating equipment, plays a crucial role. The winding device transports the base material (such as pet film, metal strip, plastic film and other flexible materials) to be coated to the coating area at a certain speed and tension through the unwinding roller and the over roller in the winding device. After the coating is completed, the winding roller rewinds the coated base material into a cylindrical film, which is convenient for subsequent collection, storage and processing.
[0023] However, the existing winding device has poor tension control effect during the base material conveying process, which can cause the base material to break and affect the normal work of the coating equipment.
