Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of spraying equipment, in particular to a multi-angle spraying device for a wheelchair frame. Background Art
[0002] A sprayer is a special coating equipment that uses spraying technology. The principle is to control the airflow to instantly push the air distribution reversing device to reverse, so that the piston of the pneumatic motor can make a stable and continuous reciprocating motion, pressurize the inhaled paint, and transport the paint to the spray gun of the sprayer through a high-pressure hose. The spray gun instantly atomizes the paint and releases it to the surface of the object to be coated. The sprayer is mainly composed of a feeding device, a spray gun, and an atomization source. It is suitable for industries such as industry and automobile manufacturing.
[0003] During the production process of existing wheelchair frames, it is necessary to perform anti-rust spraying on the wheelchair frames. The spraying machine is usually operated by a staff member to spray the wheelchair frame. The wheelchair frame is suspended on a workbench. Since the frame is composed of multiple different brackets, it is necessary to constantly change the position, height and angle for spraying during the spraying process. Therefore, long-term spraying work may easily lead to uneven spraying and reduce the spraying efficiency of the sprayer. During spraying, the sprayer is completely controlled by the staff holding the spray head to control the spraying angle. The staff may easily inhale a large amount of spraying materials when spraying at close range for a long time, which may easily cause health and other safety hazards. Utility Model Content

The spraying machine is usually operated by a staff member to control the spray head for spraying, and the wheelchair frame is suspended on a workbench. Since the frame is composed of multiple different brackets, it is necessary to constantly change the orientation, height and angle for spraying during the spraying process. Therefore, under long-term spraying work, it is easy to cause uneven spraying and reduce the spraying efficiency of the sprayer. When spraying, the sprayer completely controls the spraying angle by the staff holding the nozzle. The staff is prone to inhaling a large amount of spraying raw materials when spraying at close range for a long time, which is easy to cause technical problems such as health hazards.
