Problems solved by technology

However, since the material liquid coated by the coating roller is often relatively viscous and easy to agglomerate, the existing reflux device is prone to blockage of the reflux channel when the material liquid is refluxed and filtered. The splashed material liquid will pollute the equipment and products and form waste products

Abstract

The present application discloses a novel backflow device for a coating machine, which is characterized in that the new backflow device for a coating machine includes: a trough, a backflow pipe, an overflow baffle, an overflow pipe, an overflow height pipe, a Level reflux tank, the first and second level reflux tank, the second and second level reflux tank, several filter devices, some valves and material liquid pumping device, the material trough, the first-level reflux tank and two secondary reflux tanks from Arranged in order from high to low. Through the technical solution in this application, the material liquid can be recycled smoothly, especially when filtering high-viscosity fluid, the two-stage alternating filtration can filter out the impurities in the fluid as much as possible, and can also prevent the overflow pipe from being blocked The splashing of the material liquid reduces the pollution to the equipment and products, makes the equipment more flexible and effective in use, and improves the function and performance of the equipment.

Description

technical field [0001] The present application relates to the field of coating machines, in particular to a novel reflow device for coating machines. Background technique [0002] The coating machine is mainly used for the surface coating process production of film, paper, etc. This machine is to coat the rolled substrate with a layer of glue, paint or ink with specific functions, and then wind it up after drying. In existing actual production, the rotation of the coating stick in the trough will pollute the feed liquid, and if the impurities in the polluted liquid are not cleaned up, the quality of the finished product will be affected. The main task of the filter device is to separate the impurities from the fluid, and it should try to ensure that the impurities in the fluid are as small as possible. However, since the material liquid coated by the coating roller is often relatively viscous and easy to agglomerate, the existing reflux device is prone to blockage of the re...
