Boat spray painting machine system

Abstract

An automatic boat spray painting line comprises a coating spray gun, a compressed air loop, a coating loop and a washing loop, wherein the output end of the compressed air loop is communicated with a power input hole of the coating spray gun, the output end of the coating loop and the output end of the washing loop share a section of pipeline and are communicated with a coating input hole of the coating spray gun, and the input end of the compressed air loop and the input end of the coating loop are communicated with the output end of an air compressor. According to the automatic boat spray painting line, compressed air is taken as power for spray painting, opening and closing operation can be performed on spray guns with different serial numbers to change the spraying swath of the spray guns, it is ensured that high-viscosity coatings in a coating container are always in a stirred state and not solidified to block an inner hole of the spray gun, working states of all the executive components are automatically executed by a control system on the basis of operation content and operation requirements according to design instructions, working efficiency is high, and the spray painting thickness is even.

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
