The invention provides a knife
coating system used for an isolating
mesh grid. By the adoption of the knife
coating system for the isolating
mesh grid, the technical problems that when an existing knife
coating device is used for knife coating of the isolating
mesh grid, the knife coating width of a scraping knife cannot be adjusted, knife coating cannot be conducted on a plurality of mesh grids with different widths at the same time, and using is monotonic. The knife
coating system for the isolating mesh grid comprises a
machine frame. A scraping knife is fixed to the
machine frame. A working cavity is formed in the scraping knife. A feed inlet communicated with the working cavity is formed in the lateral portion of the scraping knife. A feeding mechanism which can convey paint to the feed inlet is arranged on the
machine frame. A plurality of
discharge outlets which are communicated with the working cavity are formed in the lower portion of the scraping knife. A regulation and control mechanism which can seal any
discharge outlet is further arranged on the machine frame. A coating knife roller is arranged below the scraping knife and connected with a lifting mechanism which can drive the coating knife roller to rise and fall and can make contact with the scraping knife. A monitoring mechanism which can monitor the flow abnormity of the
discharge outlets is further arranged on the scraping knife. The knife
coating system used for the isolating mesh grid has the
advantage of being high in practicability.
