| Zusammenfassung: | The utility model discloses an edge coating pressure stabilizing system. The edge coating pressure stabilizing system comprises a feeding screw pump, a needle valve, a three-way valve, a coating pressure sensor and a backflow pressure sensor, wherein the three-way valve is respectively communicated with the coating head, the feeding screw pump and the needle valve through pipelines, the needle valve is communicated with the feeding screw pump through a pipeline, the backflow pressure sensor is arranged on the pipeline between the needle valve and the feeding screw pump, and the coating pressure sensor is arranged on the pipeline between the three-way valve and the coating head. Edge coating pressure stabilizing system, a needle valve, a three-way valve and a pressure sensor are adopted. Feeding screw pump, therefore, the problem that the pressure rises slowly when small-flow coating is started is solved; in order to solve the problems of low coating pressure and high initial poor proportion of a coating produ |
