The working principle of the adhesive coating machine is the same, but its performance is different according to the model and manufacturer. The vertical frame of the adhesive coating machine is equipped with a device that can clamp the screen frame. In front of and behind the screen area is a horizontal coating mechanism, which consists of a coating slot and mechanical or pneumatic components for controlling the angle and pressure of the coating slot. The two ends of the coating mechanism are installed on the vertical support arm of the adhesive coating machine. Through the transmission of belts, chains or cables, the coating mechanism moves up and down to coat along the surface of the screen. The transmission mechanism is connected to the servo or variable frequency motor, so that it can run smoothly and accurately control the position of the coating mechanism.

Before coating, the cleaned and stretched screen is loaded from the front of the adhesive coater, and some models can also load the screen from the side. In models designed for large frame screens, the side layout is more common, because the screen frame is large and heavy, and the side layout can make the lifting movement smaller. When the automatic screen coater runs online with other automatic screen processing equipment, it is more convenient to install the plate from the side. Regardless of how the screen is installed, once the screen is in the correct position, the pneumatic clamping device or mechanical clamping device will close to lock the screen.

In order to make the operation more convenient, many models of adhesive coating machines have pedals to control the action of the plate clamp, and the operator can free up his hands to control the screen. After installing the screen, pour the corresponding emulsion into the automatic coating machine to start coating. Depending on the control system and the function of the device, the device can coat both sides of the screen at the same time. There are two coating methods. One is to apply photosensitive glue on the screen by repeated wet pressing. Or a drying process is added after each coating. A machine for the quantitative application of a liquid polymeric material to the surface of a material.

The problem of wear of the transmission parts of the self-adhesive coating machine often occurs during operation, such as the wear of the drying shaft of the self-adhesive coating machine, the wear of the bearing chamber of the winding roller, etc. Traditional repair methods include surfacing, thermal spraying, brush plating, etc. But there are some shortcomings: surfacing will make the surface of the parts reach a very high temperature, produce deformation or cracks, and break the shaft in severe cases; the electroplating coating cannot be too thick, the pollution is serious, and the application is limited.
