With the progress of the times, coating equipment is also constantly updated, from the ancient brush coating machine to various advanced coating machines today, it is still being updated and improved, in order to make the coating The work has become easier and simpler. I don’t know if you have known about the coating machine? There are many types of it, such as the brush coating machine just mentioned, the scraper coating machine, the spray coating machine, etc. . Next, let's come to Coating Online to explain to you a very important aspect of the coating machine, that is how to clean the coating machine, come and see it with us!



We need to use glue tank, ethyl acetate applicator roller for cleaning. While rotating the coating roller at a slow speed, apply the plate washing solution on the surface with a paint brush, and then let it stand for 5-10 minutes. Then add 10L ethyl acetate into the tank to contact the coating roller, and slowly rotate the coating roller, and wash it with a wire brush and waste cloth until it is cleaned. 3 ~ 5L of ethyl acetate is prepared from the top of the applicator roll with the scrubbing side of the waste shower. Scrub the applicator roller with clean dry waste, ethyl acetate and buffer tank extraction in the extraction tank. The cleaning cycle of the coating equipment manufacturer can be determined according to the appearance of the product. Generally, it is better to clean once a week or two weeks. According to the maintenance and cleaning equipment of the above method, the service life of the machine can be extended.



Reasons and solutions for the phenomenon of different lengths in the coating machine;



Mechanical equipment now plays a very important role in people's production and life. All kinds of mechanical equipment are widely used in various purposes because of their different characteristics. Coating machine is a kind of mechanical equipment that is widely used in people's life. When using a coating machine for processing, sometimes it is found that some situations of different lengths will occur during the operation of the coating machine. Next, I will introduce some reasons for this phenomenon and some corresponding solutions. .



Reasons: (1) The blade of the cutting knife is too blunt, and it is easy to pull out the surface layer of the cut object to make the specifications inconsistent; (2) The cutting knife is not perpendicular to the worktable; (3) The front surface of the paper pusher and the surface of the worktable If it is not vertical, the paper pusher is tilted forward, and the cut paper stack is long at the top and short at the bottom; the paper pusher is tilted backward, and the cut paper stack is short at the top and long at the bottom; Correspondingly, the anti-cutting knife of the paper stack is larger, thereby increasing the bending deformation of the paper stack, and the paper stack after cutting appears to be long at the top and short at the bottom. Therefore, the height of the stack of paper should be controlled below 100mm, and the thickness of the paper is different, and the corresponding cutting height should also be adjusted appropriately.


Solution: Then it is necessary to improve the equipment component of the frequency converter in the components of the coating equipment. The tension control at all levels is completed by the frequency converter, and the tension sensor is used to realize the tension control. The system is simple and stable. Use a PLC or a synchronous controller to control the speed of the drive roller inverter, and at the same time use it as the line speed signal of other inverters, so as to reduce the above-mentioned adverse phenomena in the coating machine.
