Troubleshooting
Coating machine drive parts wear
During the operation of the coater, the wear of the transmission part often occurs, such as the wear of the dryer shaft of the coater and the wear of the bearing chamber of the roll paper. The traditional repair methods include surfacing, thermal spraying, brush plating, etc., but all have certain drawbacks: surfacing will cause the surface of the part to reach a very high temperature, causing deformation or cracking, and in severe cases, the shaft will be broken; electroplating plating It should not be too thick, and the pollution is serious, and the application is also limited. The material has good adhesion and compressive strength, and can be used to repair the wear of the coater without disassembly. At the same time, because of its metal-deficient concession, it can absorb the shock vibration of the equipment and avoid secondary wear.
Coater concrete foundation damage
Due to corrosion, aging, equipment vibration and other factors, the coating machine will also cause damage to the concrete base and other parts, resulting in loosening of the bolts of the fastening equipment, which seriously affects production. The traditional concrete pouring method will make the repair time greatly prolonged, which is difficult for enterprises to accept.
work process
Roll the substrate, such as paper, cloth, leather, aluminum foil, plastic film, etc., with a layer of glue, paint or ink of a specific function, and dry it to wind up. The working principle of the automatic coater: The working principle of the automatic coater for screen printing is the same, but its performance varies according to different models and different manufacturers. The screen coater is provided with a device capable of clamping the frame on the vertical frame. The front and rear of the screen area is a horizontal coating mechanism consisting of a coating tank and mechanical or pneumatic components that control the angle and pressure of the coating tank.
Both ends of the coating mechanism are mounted on the vertical support arm of the coater, 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 coating, the clean, stretched screen is loaded from the front of the coater, and some models can also be loaded into the screen from the side. Among the models designed for large format frames, side loading is more common because the frame is large and bulky, and the side loading allows for a smaller amount of lift and movement. When the automatic screen coater is operated online with other automatic screen processing equipment (such as cleaning equipment, recycling equipment, drying equipment and developing machine), it is more convenient to mount from the side.
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 his hands to control the screen. After the screen is installed and the corresponding emulsion is poured into the automatic coater, the coating can be started. Depending on the function of the control system and equipment, the equipment can simultaneously coat both sides of the screen.
There are two coating methods, one is to apply the emulsion on the screen by a plurality of wet-wet operations, or to add a drying process after each coating. A machine for metering a liquid (or melt) polymer material such as a binder or a coating on a surface of a material.
Suitable for the production of soft substrates such as PVC/PE film
Simply put, the glue is applied to the film. Specific includes coating, drying, winding and tension control.
The film can be PVC, PE, PET... or some paper, such as hot-melt adhesive on the release paper.
