How to solve the problem of wear and tear during the use of optical film coating machines? During the operation of the coating machine, there are often problems with wear on the transmission parts, such as wear on the drying cylinder shaft head of the coating machine and wear on the bearing chamber of the paper roll. Traditional repair methods include overlay welding, thermal spraying, brush plating, etc., but they all have certain drawbacks: overlay welding can cause the surface of the parts to reach a high temperature, causing deformation or cracks, and in severe cases, it can also lead to shaft fracture; The electroplating coating should not be too thick, and the pollution is severe, which also limits its application.
Before coating, the clean and stretched mesh plate of the coating machine can be loaded into the front of the coating machine, and some models can also be loaded into the mesh plate from the side. In models designed for large format mesh frames, side mounting is more common because the mesh frame is large and bulky, and side mounting can reduce the lifting and moving amount. When the automatic screen coating machine is running online with other automatic screen processing equipment (such as cleaning equipment, regeneration equipment, drying device, and developer), it is more convenient to install plates from the side.
No matter how the screen is installed, once the screen is in the correct position, the pneumatic or mechanical clamping device closes, locking the screen. For more convenient operation, many models have foot pedals to control the clamp movement, allowing operators to free up their hands to control the screen. After installing the screen, pour the corresponding photosensitive emulsion into the automatic coating machine to start coating. According to the functions of the control system and equipment, the equipment can simultaneously coat both sides of the screen.
The coating machine has a cutting blade that does not fall in place, resulting in a phenomenon of continuous cutting; The falling height of the cutting blade is too low, causing the blade marks to be too deep, resulting in uneven or cracked cuts. The normal depth of the cutting blade entering the blade is 0.5-1mm; Blunt blade and uneven blade can also lead to phenomena such as continuous cutting or uneven cuts.
