    Working principle of automatic coating machine

    Date:2015.12 source:GUANGSHENG MACHINERY

    The working principle of automatic coating machine for screen printing plate is the same, but its performance is different according to different models and different manufacturers. A device for clamping a net frame is arranged on a vertical frame. Before and after the screen area is the level of coating, the coating mechanism from the coating slot, as well as the control of the angle and pressure of the coating of mechanical components or pneumatic components. The coating mechanism is arranged on the vertical supporting arm of the coating machine, through the transmission of the belt, the chain or the cable, and the coating mechanism is moving up and down, and is coated on the surface of the screen. The driving mechanism is connected with the servo or frequency conversion motor to operate stably, and can accurately control the position of the coating mechanism. Before coating, clean, good stretch net screen coating machine from the front loaded, some models can also be loaded from the side of the screen. In large format screen frame design models, side mounted version of the more common, because the screen frame is big and heavy, the side plate is installed, the amount of uplift and move. In the automatic screen coating machine and other automatic wire mesh processing equipment (such as cleaning equipment, recycling equipment, drying equipment and developing machine) on line running, from the side of the plate is more convenient. No matter how to install the screen. Once the screen is in the correct position, pneumatic clamping device or mechanical clamping device is closed, the lock screen. In order to operate more convenient, many models have foot pedal control version of the clip action, the operator can vacate hands to control the screen. Install screen, to automatic coating filled in the emulsion after corresponding to coating. According to the function of the control system and equipment, the equipment can be coated on both sides of the screen simultaneously. Coating method has two kinds, one is through the wet and wet pressing operation on screen coated emulsion; or after each coating plus drying process. Machine for quantitatively coating liquid (or melt) polymer material on the surface of a material.
