Boat sprayer system

Abstract

The invention discloses a boat spraying automatic line, which comprises a coating spraying gun, compressed air loops, a coating loop and a cleaning loop. The output ends of the compressed air loops communicate with power input holes of the coating spraying gun; the output ends of the coating loop and the cleaning loop share a section of pipeline to communicate with coating input holes of the coating spraying gun; and the input ends of the compressed air loops and the coating loop communicate with the output end of an air compressor. According to the boat spraying automatic line, spraying is conducted by adopting compressed air as power, coating spraying guns with different numbers can be started and stopped, the magnitude of the spraying width of the spraying guns is changed, it is guaranteed that high-viscosity coating is always in a stirring state in a coating container, is not solidified and does not block inner holes of the spraying guns, the working states of all implementing component are all automatically executed through a control system by design instructions according to the operation content and operation requirements, the working efficiency is high, and the spraying thickness is uniform.

Description

technical field [0001] The invention relates to the processing of powder metallurgy products, in particular to an automatic boat spraying line. Background technique [0002] High-temperature sintering of workpieces pressed and formed in the powder metallurgy industry In order to prevent the workpiece from bonding to the high-temperature-resistant boat, a layer of special coating mainly composed of graphite is applied to the surface of the boat. The surface of the painted paint layer is required to be smooth and uniform in thickness, and different paint thicknesses should be changed according to different grades of materials. Coating production process factors Carbide production industry only adopts manual brushing process for boat coatings. Manual brushing of boats is highly dependent on personal skills and experience, and it is difficult to ensure that the paint on the surface of the boat is uniform in thickness. The brush marks caused by the movement of the brush also ser...

Problems solved by technology

Manual brushing of boats is highly dependent on personal skills and experience, and it is difficult to ensure that the paint on the surface of the boat is uniform in thickness. The brush marks caused by the movement of the brush also seriously affect the flatness, which affects the surface Coarseness and deformation have a direct impact on
