Embodiment Construction

[0027] The present invention will be described in further detail below.

[0028] A high-pressure airless spraying device for piano shells, including an air source, a gas booster, a material pump, a material barrel, a curing agent pump, a curing agent barrel, a static mixer, a spray gun, a spray cap, a nozzle, two return valves, and a pressure tank , General air intake switch, pneumatic air source switch, air source regulating valve, pressure tank air source switch, cleaning switch, A switch, B switch.

[0029] The air booster is an air motor, which is used to transmit and pressurize the gas, and finally drive the material pump and curing agent pump to run. Both the material pump and the curing agent pump are live column pumps, which are used to change low-pressure liquid into high-pressure liquid, including gas inlet, low-pressure liquid inlet, and high-pressure liquid outlet. The function of the static mixer is to mix two high-pressure liquids evenly. The nozzle is a 417 ty...

Abstract

The invention relates to a piano shell high-pressure airless spraying device and relates to piano processing equipment. The piano shell high-pressure airless spraying device comprises an air source, an air supercharging part, a material pump, a material barrel, a curing agent pump, a curing agent barrel, a static mixer, a spray gun and a spray nozzle. The air source is connected with the air supercharging part through a pipeline. The air supercharging part is connected with the material pump and the curing agent pump through pipeline correspondingly. The material barrel, the material pump andthe static mixer are connected through a pipeline in sequence. The curing agent barrel, the curing agent pump and the static mixer are connected through a pipeline in sequence. The static mixer is connected with the spray gun through a pipeline. The spray nozzle is connected to the spray gun. According to the characteristic that little paint mist is rebounded during high-pressure airless spraying,the problems that paint mist generated during low-pressure mixed gas spraying is splashed and other surfaces are contaminated with the splashed paint in the prior art are solved; grinding abrasive paper is saved, damage to health of operators is reduced, and the spraying environment is improved.

Description

technical field [0001] The invention relates to piano processing technology, in particular to a high-pressure airless spraying device for piano shells. Background technique [0002] Unsaturated polyester resin paint (referred to as PE paint) is used for the finishing of piano shell workpieces. The original spraying method is to use low-pressure air spraying, which has a serious rebound phenomenon. Due to paint mist and paint splashing, other non-painted parts of the workpiece have the problem of paint sticking. When entering the next sanding process, it takes a lot of time and sandpaper consumption, and the air pollution is relatively large; the utilization rate of air spray paint is low, which is 20% -30%, large paint waste. [0003] High-pressure airless spraying is a relatively advanced spraying method. It uses a high-pressure plunger pump to increase the paint to a high pressure (common pressure 60-300kg / cm2), and the high-pressure paint is transported to the spray gun ...
