Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a sheet metal spraying device for recycling scrap materials. Background Technology

[0002] Sheet metal coating is a key process for improving the corrosion resistance and appearance of sheet metal parts. First, the sheet metal parts undergo pretreatment such as degreasing and rust removal to ensure surface cleanliness. Next, powder or liquid coating is evenly applied to the workpiece surface using spraying techniques. Finally, the coating is cured by baking, forming a tough coating. This process enhances the protective performance and decorative effect of sheet metal parts and is widely used in the automotive, home appliance, and machinery industries. However, careful attention must be paid to coating selection and process control to ensure quality and reduce environmental pollution.

[0003] In the actual spraying process, when the paint adheres to the surface of the sheet metal parts, it will still encounter the situation of repeated paint adhesion, and then the paint will drip. Currently, during the spraying process, the paint will drip directly onto the ground, causing waste and not being fully recycled.

[0004] Therefore, a scrap material recycling type sheet metal spraying device is proposed to solve or alleviate the above problems. Utility Model Content

[0026] A casing 23 is provided on the outer side of the frame 2. A door groove 24 is provided on one side of the casing 23. A sealing plate 25 is detachably connected inside the door groove 24. A guide plate 26 embedded in the frame 2 is fixedly connected to the inner side of the sealing plate 25 and the inner side wall of the casing 23. The thickness of the guide plate 26 gradually increases from top to bottom. The spraying component is connected to the recovery tank 3. A three-way connector 11 and a pump body 13 are connected on the communication path between the spraying component and the recovery tank 3. The connection between the recovery tank 3 and the spraying component can be switched on and off. The three-way connector 11 can guide external paint into the tank.

[0027] The top of the housing 23 is fixedly connected to the connecting frame 27, and the upper end of the suspension assembly is fixedly connected to the connecting frame 27. The suspension assembly includes a connecting rod 20, a screw cylinder 19 fixedly connected to the lower end of the connecting rod 20, a stud 18 threadedly connected to the screw cylinder 19, and a hook 17 fixedly connected to the lower end of the stud 18. The screw cylinder 19 penetrates the top plate 4 into the frame 2.

[0028] The rotating assembly includes a connecting sleeve 22 sleeved on the outside of the screw barrel 19 and extending through the top plate 4, a turntable fixedly connected to the lower end of the connecting sleeve 22 and sleeved on the outside of the screw barrel 19, a driven disc 21 fixedly connected to the upper end of the connecting sleeve 22 and located outside the connecting rod 20, and a drive motor 28 fixedly connected to the connecting frame 27 and vertically arranged.

[0029] The spraying assembly includes a vertical pipe 6 fixedly connected to the bottom of the turntable, spray nozzles 7 connected to the vertical pipe 6 and evenly spaced along its height, and a movable pipe 8 that penetrates the turntable and connects to the upper end of the vertical pipe 6. A near-annular groove 5 with an arc angle of less than 360° is provided on the top plate 4. The movable pipe 8 passes through the near-annular groove 5 and slides therein. The upper end of the movable pipe 8 is connected to a metal corrugated pipe 10 through a rotary pipe joint 9. The recovery tank 3 is connected to a recovery pipe that penetrates the housing 23.

[0030] In practical use, this invention only requires opening the sealing plate 25, then suspending the sheet metal parts to be painted via the hook 17. The stud 18 and screw barrel 19 are adjusted according to the height of the sheet metal parts, allowing the stud 18 to be threaded into the screw barrel 19, thus adjusting their usable length to ensure the sheet metal parts are within the spray range of the nozzles 7. The operator then re-inserts the guide plate 26 and sealing plate 25 into the door groove 24, and then starts the drive motor 28 and pump body 13. The pump body 13 draws external paint through the tee connector 11, pump body 13, metal bellows 10, rotary pipe connector 9, and movable pipe 8 into the vertical pipe 6. Under continuous pressure, the paint in the vertical pipe 6 is sprayed onto the sheet metal part through the nozzle 7. During this process, the drive motor 28 drives the active disc 29 to rotate, which in turn drives the passive disc 21 to rotate. When the passive disc 21 rotates, it drives the connecting sleeve 22 to rotate. The lower end of the connecting sleeve 22 drives the vertical pipe 6 to rotate around the outer ring of the screw barrel 19 through the turntable. This allows the spraying assembly to reciprocate around the sheet metal part in the middle, ensuring that the surface of the sheet metal part is evenly sprayed. The paint that falls off the sheet metal part during this process can be recovered by the recycling tank 3. After a certain amount of paint accumulates in the recycling tank 3, it can re-enter the metal bellows 10 through the recycling pipe and the solenoid valve 16 in sequence, so that the paint can be recycled.
