System for electrostatically spraying wooden guitar by adopting photosensitive paint, and painting method

Abstract

The invention discloses a system for electrostatically spraying a wooden guitar by adopting photosensitive paint. The spraying system is positioned in a closed space and comprises a circulating transportation track, an automatic electrostatic dust removing device, a manual paint repairing and spraying chamber, an electrostatic paint spraying chamber and a curing chamber, wherein the automatic electrostatic dust removing device, the manual paint repairing and spraying chamber, the electrostatic paint spraying chamber and the curing chamber are sequentially arrayed along the transportation track; the closed space is provided with an inlet for blowing wet wind; the electrostatic paint spraying chamber is internally provided with a butterfly-shaped spray nozzle; the butterfly-shaped spray nozzle is connected with a photosensitive paint pipe; the photosensitive paint pipe is connected with a pressure barrel filled with the photosensitive paint; the three walls of the electrostatic paint spraying chamber are provided with water curtains; the water curtains are connected with a water inlet pipe and a water outlet pipe; the curing chamber is internally provided with a strong ultraviolet transmitting device; and a wooden guitar workpiece is hung on the transportation track. The invention also discloses a spraying method of the system for electrostatically spraying the wooden guitar by adopting the photosensitive paint. The method has low cost, environmental protection and high production efficiency.

Description

technical field [0001] The invention relates to the technical field of electrostatic spraying, in particular to a system and a spraying method for electrostatically spraying wooden guitars with photosensitive varnish. Background technique [0002] The current spraying process for wooden guitars is as follows: spray PU sealing paint on the first day, polish the PU sealing paint and spray PE primer on the second day, polish the PE primer until smooth on the third day, repair the color on the fourth day, and spray two times on the fifth day. First PU topcoat, polished on the sixth day, sprayed PU topcoat twice on the seventh day, polished on the eighth day, polished on the ninth day, and inspected. Re-polished. Such a process takes a long time and is prone to quality problems such as sagging and uneven paint film. It requires a lot of manpower and material resources, high cost, low production efficiency, is not environmentally friendly, and discharges more waste water, waste d...
