Filter, feeding mechanism and coating equipment

Abstract

The utility model relates to the technical field of fluid filtration, and specifically discloses a filter, a feeding mechanism and a coating equipment, the filter comprises a shell, a filter screen and a buffer, the shell is equipped with a liquid inlet and a liquid outlet, the filter screen is located in the shell, a first flow channel that communicates with the liquid inlet is arranged inside the filter screen, the filter screen and the inner wall of the shell jointly form a second flow channel that communicates with the liquid outlet, the buffer is located in the filter screen and is used for absorbing the impact force of fluid, that is, the filter screen is interposed between the first flow channel and the second flow channel, after fluid enters the first flow channel, it will be filtered into the second flow channel through the filter screen, the pressure difference between the two sides of the filter screen will increase during the filtration process, which will cause pressure fluctuation and affect the coating quality and consistency, therefore, the buffer can absorb part of the impact force and reduce pressure fluctuation, and when it is applied in the feeding mechanism and the coating equipment, the coating quality and consistency can be effectively improved.
