The coating machine for canvas is a coating device for canvas, and its performance varies according to different models and different manufacturers. The coating machine for canvas is provided with a device capable of clamping the frame on the vertical frame, and the front and rear of the screen area is a horizontal coating mechanism.
Both ends of the coating mechanism are mounted on the vertical support arm of the coating machine, and the coating mechanism is moved up and down by the belt, chain or cable transmission, and coated along the surface of the screen. The transmission is connected to a servo or variable frequency motor for smooth operation and precise control of the position of the coating mechanism.
Before the coating machine for canvas is applied, the clean, stretched screen is loaded from the front of the coating machine, and some models can also be loaded into the screen from the side. In models designed for large format frames, side mounting is more common because the frame is large and bulky, and the side loading allows for a smaller amount of lift and movement. Regardless of how the screen is installed, once the screen is in the correct position, the pneumatic clamp or mechanical clamp is closed and the screen is locked.
In order to make the operation more convenient, many models have pedals to control the folder movement, and the operator can free up his hands to control the screen. After the screen is installed and the corresponding emulsion is poured into the automatic coating machine, the coating can be started according to the functions of the control system and the device, and the device can simultaneously coat both sides of the screen.
