Description

Technical Field

[0001] This utility model belongs to the field of spray painting, and specifically relates to a rapid spray painting device for workpieces. Background Technology

[0002] The manufacturing process of metal workpieces requires multiple machining procedures. Usually, in order to extend the service life of the workpieces and prevent them from being corroded, paint needs to be sprayed on the surface of the workpieces to protect them and extend their service life.

[0003] Most existing spray painting processes rely on manual spraying. Due to the limitations of manual operation, the spraying process is slow, the paint effect is poor, and paint is easily wasted. Furthermore, prolonged exposure to paint can negatively impact the health of spray painting workers. Utility Model Content

[0005] The purpose of this utility model is achieved as follows: A rapid painting device for workpieces includes a painting chamber. The front side of the painting chamber is provided with a feed inlet, and the rear side of the painting chamber is provided with a discharge outlet. The interior of the painting chamber is provided with a painting mechanism and a feeding mechanism that are corresponding to each other. The painting mechanism includes two upper guide rails set on the top of the inner wall of the painting chamber. A movable seat is movably connected to the upper guide rails. A paint tank is provided on the lower side of the movable seat. Several vertical spray pipes are provided at the bottom of the paint tank. The lower end of the spray pipes is provided with a nozzle. The feeding mechanism includes two parallel lower guide rails. A feeding seat is movably connected to the lower guide rails. The upper outer perimeter of the feeding seat is provided with vertical rails.

[0006] In operation, the workpiece is placed on the feeding seat. The rectangular feeding seat's surrounding railings protect the workpiece from falling. Then, the spray nozzle above sprays paint onto the workpiece. When a certain amount of paint has been applied, the feeding seat conveys the workpiece backward, while the moving seat above also moves backward and remains stationary relative to the feeding seat. The spray nozzle continues to spray paint onto the workpiece until it reaches the discharge port, at which point the spray nozzle stops working, and the workpiece is removed from the feeding seat. Compared to existing technologies, the advantages of this invention are: improved painting speed and efficiency, more uniform paint distribution on the workpiece, and a high degree of automation; when not in use, both the front and rear doors are closed to prevent injury to personnel.

[0007] As a further improvement of this utility model, both the upper guide rail and the lower guide rail are parallel to the length direction of the spray booth, and both the lower guide rail and the spray booth are mounted on the base.

[0008] As a further improvement of this utility model, the front side of the spray booth is provided with an openable front door corresponding to the feed inlet, and the rear side of the spray booth is provided with an openable rear door corresponding to the discharge outlet.

[0009] As a further improvement of this utility model, the paint tank is connected to the paint source via a flexible hose. A paint pump is installed on the spray pipe, which sprays the paint inside the paint tank downwards through the nozzle to paint the workpiece.

[0010] As a further improvement of this utility model, the upper side of the movable seat is provided with two symmetrical T-shaped sliders, which are movably connected to the T-shaped grooves of the corresponding upper guide rails. A rack is provided along the length direction on the outer side of any of the upper guide rails. A reduction motor is vertically mounted on the side of the movable seat via a bracket. A gear is provided at the output end of the reduction motor, and the gear meshes with the rack. The lower side of the feeding seat is provided with two symmetrical sliders, which are movably connected to the grooves of the corresponding lower guide rails. A rack is provided along the length direction on the inner side of any of the lower guide rails. The feeding seat is hollow inside. A vertical reduction motor is installed in the mounting groove inside the feeding seat. The output shaft of the reduction motor passes downward through the feeding seat and is equipped with a gear, which meshes with the rack. The reduction motor drives the gear to roll along the rack, causing the movable seat to move back and forth. The reduction motor drives the gear to roll along the rack, causing the feeding seat to move back and forth.

[0011] As a further improvement of this utility model, the upper surface of the feeding seat is provided with a rotatable rotating seat, on which a vertical rod is provided, and several side hanging rods are provided on the outer periphery of the vertical rod. Each workpiece is suspended on the hanging rod, and the rotating seat drives the workpiece to rotate, so that the paint spraying on the workpiece is more uniform. Attached Figure Description
