[0019] A driving mechanism is installed on the top of the chassis 1 and is used to drive the turntable 6 to rotate in sections. The driving mechanism includes a first motor 12 installed on the top of the chassis 1 and a first driving shaft 13 rotatably connected to the center of the top of the chassis 1; the bottom end of the first driving shaft 13 extends to the inside of the chassis 1 and is fixedly connected to the center of the top of the turntable 6; the outside of the output shaft of the first motor 12 and the outside of the first driving shaft 13 are both fixedly sleeved with a first gear 14, and the two first gears 14 are meshed with each other; By controlling the first motor 12 to drive the first gear 14 to rotate counterclockwise, the first drive shaft 13 is driven to rotate clockwise through the meshing effect of the two first gears 14, and the turntable 6 rotates clockwise synchronously therewith. By controlling the first motor 12 to drive the turntable 6 to pause every 90° rotation, the workpieces at the bottom of the driven disk 8 on the turntable 6 are driven to rotate in sequence to above the loading and unloading area 41, the spraying area 42, the paint recovery area 43 and the curing area 44, thereby realizing the adjustment of the workpiece processing position.

[0020] The multi-purpose linkage mechanism is provided with multiple ones. In the present embodiment, the number of the multi-purpose linkage mechanisms is four. The multi-purpose linkage mechanism comprises a driven disk 8 rotatably connected to the inside of the turntable 6, multiple driven shafts 9 rotatably connected to the inside of the driven disk 8, and a hanger 10 arranged on the driven shaft 9. A linkage shaft 16 is fixedly connected to the center of the top of the driven disk 8, and the outer parts of the multiple driven shafts 9 are all fixedly sleeved with second gears 17. The outer parts of the multiple second gears 17 are provided with first gear rings 18, and the first gear rings 18 are fixedly connected to the top of the turntable 6, and the first gear rings 18 are meshed with the second gears 17; a hanging groove 24 is opened inside the driven shaft 9, and the hanger 10 is hung by The groove 24 is hung on the driven shaft 9, and the hanger 10 is used to hang the workpiece to be sprayed; the top of the chassis 1 is rotatably connected to the second drive shaft 19, and the top of the second drive shaft 19 is connected to the second motor 20, which is installed on the top of the chassis 1. The bottom end of the second drive shaft 19 extends to the inside of the chassis 1 and is fixed with a third gear 21; the inner wall of the top of the chassis 1 is rotatably connected to the second gear ring 22, and the third gear 21 is meshed with the second gear ring 22; the outside of the multiple linkage shafts 16 are all installed with a one-way gear 23, which is meshed with the second gear ring 22, and the upper edge of the one-way gear 23 is lower than the lower edge of the third gear 21; By controlling the second motor 20 to cooperate with the second driving shaft 19 to drive the third gear 21 to rotate clockwise, the meshing effect between the third gear 21 and the second gear ring 22 drives the second gear ring 22 to rotate synchronously clockwise, and the meshing effect between the second gear ring 22 and the one-way gear 23 drives the one-way gear 23 to rotate synchronously clockwise, further driving the linkage shaft 16 to rotate clockwise, and then driving the driven plate 8 to rotate, and each driven shaft 9 then revolves around the linkage shaft 16 as the center, and drives the workpiece to revolve synchronously through the hanger 10. At the same time, in this process, the meshing effect between the second gear 17 and the first gear ring 18 drives the driven shaft 9 to rotate, and then drives the workpiece to rotate through the hanger 10, thereby achieving the effect of driving the workpiece to revolve while rotating. Among them, when the one-way gear 23 rotates clockwise, it can drive the linkage shaft 16 to rotate, but when the one-way gear 23 rotates counterclockwise, it cannot drive the linkage shaft 16 to rotate. When the turntable 6 rotates clockwise, it drives each linkage shaft 16 to revolve in the clockwise direction. In this process, the one-way gear 23 is meshed with the second gear ring 22 to drive the one-way gear 23 to rotate counterclockwise. Therefore, when the turntable 6 rotates clockwise, the linkage shaft 16 does not rotate therewith, and the workpieces at the bottom of the driven disk 8 do not rotate around the linkage shaft 16 as the center.

[0021] The sealing recovery mechanism is provided with multiple ones, and each of them corresponds to multiple multi-purpose linkage mechanisms. The sealing recovery mechanism includes a scraper 11 abutting against the inner wall of the second partition plate 7 and a lifting assembly for driving the scraper 11 to rise and fall. The scraper 11 is an L-shaped structure. A filtering and exhausting device connected to the paint recovery area 43 can be provided on the back of the chassis 1. After the powder coatings at various positions are scraped into the paint recovery area 43, a small amount of powder particles raised are sucked out. The lifting assembly is connected to the multi-purpose linkage mechanism, and the lifting assembly is located inside the communication area; the lifting assembly includes a transmission shaft 25 rotatably connected to the inside of the turntable 6, a reciprocating screw 26 fixedly sleeved on the outside of the transmission shaft 25, and a lifting block 27 screwed on the outside of the reciprocating screw 26; the lifting block 27 is fixedly connected to the scraper 11; the outside of the transmission shaft 25 is fixedly sleeved with a fourth gear 28, and the outside of the linkage shaft 16 is fixedly sleeved with a toothed disc 29, and the fourth gear 28 is meshed with the toothed disc 29; After the workpiece is electrostatically sprayed by the electrostatic powder spray gun 2 above the powder spray platform 5, the turntable 6 and the second partition 7 are driven by the driving mechanism to rotate 90° clockwise along the inner wall of the chassis 1, and the bottom of the second partition 7 also rotates along the top of the powder spray platform 5. In this process, the second partition 7 scrapes the powder coating attached to the inner wall of the chassis 1 in the area above the powder spray platform 5 into the paint recovery area 43, and also scrapes the powder coating on the top of the powder spray platform 5 into the paint recovery area 43. At the same time, after the turntable 6 and the second partition 7 rotate 90°, the workpiece that has been sprayed completely enters the upper part of the paint recovery area 43, and the second motor 20 is controlled to drive the linkage shaft 16 to rotate clockwise, and the gear plate 2 9 rotates accordingly, and through the meshing effect between the toothed disc 29 and the fourth gear 28, the transmission shaft 25 and the reciprocating screw 26 are driven to rotate. When the reciprocating screw 26 rotates, it drives the lifting block 27 to move up and down along the outside of the reciprocating screw 26. In the process of the lifting block 27 moving from the top end of the reciprocating screw 26 to the bottom end thereof, it drives the scraper 11 to move downward along the inner wall of the connecting area, and scrapes the powder coating attached to the inner wall of the connecting area into the coating recovery area 43. The staff recovers the powder coating scraped into the coating recovery area 43. By timely recovering the excess powder coating in a closed environment, the problem of low recycling rate of the powder coating due to moisture and agglomeration caused by untimely recovery of the powder coating is solved.

[0022] Working principle: When in use, the staff hangs multiple workpieces on each driven shaft 9 through the hanger 10 at the material inlet 15. At this time, the workpiece is above the loading and unloading area 41, and hot air is blown to the workpiece by the fan 45 to dry the workpiece. After the workpiece is dried, the workpiece is driven by the driving mechanism to rotate to the top of the powder spraying platform 5, and the workpiece is electrostatically sprayed by the electrostatic powder spraying gun 2. The powder coating is adsorbed on the surface of the workpiece, and in this process, the second motor 20 is controlled to cooperate with the second drive shaft 19 to drive the third gear 21 to rotate clockwise, and the meshing between the third gear 21 and the second gear ring 22 drives the second gear ring 22 to rotate synchronously clockwise, and the meshing between the second gear ring 22 and the one-way gear 23 The one-way gear 23 is driven to rotate synchronously clockwise, which further drives the linkage shaft 16 to rotate clockwise, and then drives the driven plate 8 to rotate. Each driven shaft 9 then revolves around the linkage shaft 16, and drives the workpiece to revolve synchronously through the hanger 10. At the same time, in this process, the second gear 17 is meshed with the first gear ring 18 to drive the driven shaft 9 to rotate, and then the workpiece is driven to rotate through the hanger 10, thereby achieving the effect of driving the workpiece to revolve while rotating, achieving a uniform spraying effect on multiple angles of the workpiece, and improving the quality of the workpiece spraying. After the powder spraying is completed, the turntable 6 and the second partition plate 7 are driven by the driving mechanism to rotate 90° clockwise along the inner wall of the chassis 1, and the bottom of the second partition plate 7 also rotates along the powder spraying platform 5. The top of the machine case 1 rotates, during this process, the second baffle 7 scrapes the powder coating attached to the inner wall of the machine case 1 in the area above the powder spraying platform 5 into the paint recovery area 43, and also scrapes the powder coating on the top of the powder spraying platform 5 into the paint recovery area 43. At the same time, after the turntable 6 and the second baffle 7 rotate 90 degrees, the workpiece after the spraying process completely enters the top of the paint recovery area 43. The second motor 20 is controlled to drive the linkage shaft 16 to rotate clockwise, and the gear plate 29 rotates accordingly. Through the meshing effect between the gear plate 29 and the fourth gear 28, the transmission shaft 25 and the reciprocating screw 26 are driven to rotate. When the reciprocating screw 26 rotates, it drives the lifting block 27 to move up and down along the outside of the reciprocating screw 26. When the lifting block 27 moves from the reciprocating screw 26, the lifting block 27 is moved up and down by the lifting block 27. In the process of the top end moving downward to the bottom end, the scraper strip 11 is driven to move downward along the inner wall of the connecting area, and the powder coating attached to the inner wall of the connecting area is scraped into the coating recovery area 43. The staff recovers the powder coating scraped into the coating recovery area 43. By timely recycling the excess powder coating in a closed environment, the problem of low recycling rate of the powder coating caused by moisture and agglomeration due to untimely recycling is solved. Then, the driving mechanism drives the turntable 6 and the second partition plate 7 to rotate 90°, and drives the workpiece to the top of the curing area 44. The workpiece is cured by the temperature-controlled heater 3. During the curing process, the workpiece is synchronously driven to revolve and rotate at the same time, so that each area of ​​the workpiece is evenly heated, thereby improving the uniformity of the spray curing of the workpiece.The problem of large differences in curing temperature in different areas of the workpiece affecting its molding quality is avoided. After curing is completed, the drive mechanism drives the turntable 6 and the second partition 7 to rotate 90 degrees, driving the cured workpiece to the top of the loading and unloading area 41. The staff removes the processed workpiece and puts in a new workpiece, and the cycle continues to spray the workpiece.
