Both ends of the coater are mounted on the vertical support arm of the coater, which is driven by a belt, chain or cable to make the coater move down and coat along the surface of the screen. The drive mechanism is connected to a servo or variable frequency motor, allowing smooth operation and precise control of the position of the coating mechanism.
Before the coater is used, the clean, stretched screen plate is loaded from the front of the coater, some models can also be installed from the side of the screen plate, in the model designed for the large screen frame, the side plate is more common, because the screen frame is large and bulky, and the side plate can make the lift and move momentum smaller. When the automatic screen coater is running in line with other automatic screen processing equipment, such as cleaning equipment, regeneration equipment, drying equipment and developers, it is more convenient to mount from the side.
No matter how the plate is installed, once the plate is in the correct position, the pneumatic clamping device or mechanical clamping device is closed to lock the plate. In order to operate more easily, many models have a foot pedal control plate clamp action, the operator can free hands to control the screen plate. After installing the screen plate, the automatic coating machine is filled with the corresponding emulsion, and then coating can begin. Depending on the function of the control system and equipment, the equipment can simultaneously coat both sides of the screen.
For the use of the coater, the above is its work flow, presumably you through the introduction of this article, but also have their own understanding of the work flow of the coater, later in contact with the coater, you can also better operate it.
