[0002] The plastic spraying machine is an industrial equipment used for surface treatment of objects. It can spray powdered coatings containing epoxy resin, polyester resin (plastic) and other materials onto objects. The sprayed objects are then cured in a curing furnace to obtain a complete coating to play a decorative, anti-corrosion and other functions.

[0003] Since the paint sprayed by the spray gun of the plastic spraying machine adheres to the outer surface of the workpiece in the form of spray, part of the sprayed paint will fall freely along the outer surface of the workpiece. When the existing workpiece is sprayed, a powder paint collection box is generally set under the workpiece. However, the powder paint falling into the collection box will splash a certain amount of dust, which will cause part of the paint to scatter into the surrounding environment, thereby causing a certain amount of dust pollution when the plastic spraying machine is in use, and will have a certain impact on people's spraying operation on the workpiece.

[0004] In view of the above-mentioned related technologies, the inventor believes that powder coating has the defect of splashing dust when it falls and is recovered. Therefore, a dust collection and recovery device for a plastic spraying machine is proposed to solve the above problem.

[0021] The following is combined with Figure 1-3 This application is described in further detail.

[0022] The present application discloses a dust collection and recovery device for a plastic spraying machine. Figure 1-3 A dust collection and recovery device for a plastic spraying machine comprises a movable base 1, which is used to drive a plastic spraying device 2 to move. A plastic spraying device 2 is arranged in the middle of the upper surface of the movable base 1, and a spray gun 3 is installed at the top of the plastic spraying device 2. The plastic spraying device 2 cooperates with the spray gun 3 to spray the workpiece. A collecting box 4 is fixedly installed on the upper surface of the movable base 1 near the plastic spraying device 2. A placement groove 5 is opened in the middle of the top of the collecting box 4. The collecting box 4 cooperates with the placement groove 5 to collect the plastic spraying paint. A fixed baffle 7 is fixedly installed in the middle of one end of the inner wall of the placement groove 5. The fixed baffle 7 is used to guide the paint. A support plate 8 is welded at the upper part of the inner wall of the placement groove 5 near two adjacent fixed baffles 7. The tops of both sides of the support plate 8 are hinged with movable plates 9 to support The plate 8 cooperates with the movable plate 9 to guide the paint. A number of No. 1 springs 10 are installed between the lower bottom surface of the movable plate 9 and the side wall of the support plate 8. The No. 1 spring 10 is used to drive the movable plate 9 to reset. A number of support blocks 11 are fixedly connected to the middle part of the top of the support plate 8. The support block 11 is used to place the workpiece. The cross-section of the fixed baffle plate 7 is a V-shaped structure. The upper surface of the support block 11 is an arc-shaped surface. The bottom of the collection box 4 is also provided with a collecting mechanism that is easy to fix. By placing the workpiece on the upper surface of the support block 11 for spraying, the paint that falls from the spraying falls along the upper surface of the movable plate 9 onto the inclined surface of the fixed baffle 7, and the paint is collected by the collecting mechanism at the bottom of the collection box 4 to prevent the paint from splashing a large range of dust, which reflects the overall diversion effect of the paint.

[0023] Reference Figure 3 and Figure 5The collecting mechanism includes a discharge trough 6, which is opened in the middle of the bottom end of the placement trough 5 and extends to the bottom of the front end surface of the collecting box 4. A feeding box 12 is installed inside the discharge trough 6. The feeding box 12 is used to collect the paint. Limiting blocks 17 are welded on both sides of the front end surface of the feeding box 12. A groove is opened on the outer surface of the collecting box 4 near the top of the fixed inner cavity 13. The limiting block 17 is located inside the groove. The limiting block 17 and the groove are engaged with each other. A limiting hole 18 is opened through the middle of the top of the limiting block 17. The limiting block 17 cooperates with the limiting hole 18 to place the limiting rod 16. A fixed inner cavity 13 is opened on the front end surface of the collecting box 4 near both sides of the discharge trough 6. A No. 2 spring 14 is installed at the bottom of the inner wall of the fixed inner cavity 13. The No. 2 spring 14 inside the fixed inner cavity 13 is used In order to drive the movable block 15 to move, the upper surface of the No. 2 spring 14 extends to the outside of the fixed inner cavity 13 where a movable block 15 is installed. A limiting rod 16 is welded to the middle part of the top of the movable block 15. The movable block 15 cooperates with the limiting rod 16 to limit and fix the limiting block 17. The outer diameter of the limiting rod 16 is smaller than the inner diameter of the limiting hole 18. The top of one side of the limiting rod 16 passes through the fixed inner cavity 13 and is inserted into the limiting hole 18. The limiting rod 16 and the limiting hole 18 are engaged with each other. By pulling the movable block 15, the limiting rod 16 is retracted to the inside of the fixed inner cavity 13, and the limiting block 17 is placed in the groove. The movable block 15 is released, so that the No. 2 spring 14 drives the limiting rod 16 to be inserted into the limiting hole 18, and then the limiting block 17 is fixed, which reflects the overall installation effect of the feed box 12.

[0024] The implementation principle of the dust collection and recovery device for a plastic spraying machine in the embodiment of the present application is as follows: by placing the workpiece on the upper surface of the support block 11 for plastic spraying, the paint dropped by the plastic spraying falls along the upper surface of the movable plate 9 onto the inclined surface of the fixed baffle 7, so that the paint drives the movable plate 9 to move, and the first spring 10 drives the movable plate 9 to reset, so that the paint slides down along the outer surface of the fixed baffle 7, and the feed box 12 is placed inside the discharge trough 6 to collect the paint, so that the paint falls into the feed box 12 along the opening at the bottom of the placement trough 5, and by pulling the movable block 15 makes the limiting rod 16 retract to the inside of the fixed inner cavity 13, places the limiting block 17 into the groove, loosens the movable block 15, and makes the No. 2 spring 14 drive the limiting rod 16 to be inserted into the limiting hole 18, and then fixes the limiting block 17, so that the feeding box 12 is stably placed in the discharge chute 6; compared with the prior art, this scheme has the effect of facilitating the stable collection of the falling spray paint, improves the protection effect of the environment around the spray paint equipment 2, solves the problem of dust splashing when the spray paint falls, and improves the overall spray paint processing efficiency of the workpiece.
