[0018] Please see Figures 1-6 As shown, a high-adhesion hanging shaft surface coating device includes a worktable 1, a first mounting plate 2, a second mounting plate 3, a collection box 4, a spraying assembly 5, and a purification assembly 6; A square groove 7 is provided on one side of the upper end of the workbench 1, and sliding grooves 8 are provided on both sides of one end of the workbench 1. The first mounting plate 2 is fixedly installed on one side of the upper end of the workbench 1. A rotating disk is rotatably installed on one side of the first mounting plate 2. A three-jaw chuck is fixedly installed on one end of the rotating disk. A PLC control panel 9 is fixedly installed on the other side of the first mounting plate 2. The second mounting plate 3 is slidably mounted on the other side of the upper end of the workbench 1, and one end of the second mounting plate 3 extends into the square groove 7. A clamping rod is rotatably mounted on one side of the second mounting plate 3. The collection box 4 is fixedly installed on the upper end of the workbench 1. The collection box 4 is provided with an outlet for discharging excess paint. A first motor 10 is fixedly installed on one side of the first mounting plate 2. The output end of the first motor 10 is fixedly connected to the rotating disk. The first motor 10 is electrically connected to the PLC control panel 9. A first lead screw is rotatably installed in the square slot 7. One end of the second mounting plate 3 is connected to the first lead screw. A second motor 11 is fixedly installed on one end of the worktable 1. The output end of the second motor 11 is fixedly connected to the first lead screw. The second motor 11 is electrically connected to the PLC control panel 9. Both the first motor 10 and the second motor 11 are servo motors. Spray coating component 5 includes: The placement frame 501 is slidably installed at one end of the workbench 1. A second lead screw 502 driven by a fourth motor is rotatably installed at one end of the placement frame 501. A limit rod 503 is provided on one side of the second lead screw 502. A third lead screw is rotatably installed inside the sliding groove 8. One end of the placement frame 501 is connected to the third lead screw. A round rod is fixedly installed inside the sliding groove 8 on the other side. The other end of the placement frame 501 is sleeved on the outside of the round rod. A third motor 12 is fixedly installed at one end of the workbench 1. The output end of the third motor 12 is fixedly connected to the third lead screw. The third motor 12 is electrically connected to the PLC control panel 9. One end of the fourth motor is fixedly installed on one side of the placement frame 501 and electrically connected to the PLC control panel 9. Both the third motor 12 and the fourth motor are servo motors. The movable block 504 is connected to the second lead screw 502 at one end and sleeved on the outside of the limit rod 503 at the other end. A cavity is opened inside the movable block 504 and an atomizing nozzle is fixedly installed at the lower end of the movable block 504. Storage box 505 is fixedly installed at one end of placement rack 501. A pneumatic diaphragm pump 506 is fixedly installed on the upper end of storage box 505. The output end of pneumatic diaphragm pump 506 is connected to the cavity via a pipe. During use, the third motor 12 is manually started via PLC control panel 9 according to the diameter of the lifting shaft. The third motor 12 drives the third lead screw in sliding groove 8 to rotate, causing placement rack 501 to move along sliding groove 8 (in conjunction with the limit rod on the other side) until the atomizing nozzle is aligned with the area to be sprayed on the lifting shaft. Simultaneously, the fourth motor drives the second lead screw 502 on placement rack 501 to rotate, causing moving block 504 to move along the limit rod 503 to the left. Move to the right to adjust the position of the atomizing nozzle, and then start the pneumatic diaphragm pump 506 at the top of the storage tank 505. The pneumatic diaphragm pump 506 delivers the paint in the storage tank 505 to the cavity of the moving block 504 at a stable pressure (adjusted by the PLC control panel 9 to avoid pressure fluctuations causing uneven coating). After being atomized by the atomizing nozzle at the bottom of the moving block 504, it is evenly sprayed onto the surface of the rotating shaft, ensuring that the paint forms a coating with "consistent thickness and no missed spray" on the surface of the shaft. Excess paint that does not adhere to the surface of the shaft during the spraying process will drip into the collection box 4 at the top of the workbench 1 for easy recycling and reuse, reducing material waste.

[0019] Purification component 6 includes: The suction hood 601 is fixedly installed on the inner wall of the collection box 4. The inner side of the suction hood 601 is equipped with partitions in a linear array. One end of the suction hood 601 is equipped with an air supply pipe 602 in a linear array. The inner sides of the suction hood 601 and the air supply pipe 602 are coated with polytetrafluoroethylene. Purification box 603 is fixedly installed at one end of gas supply pipe 602. Purification plate 604 is installed inside one end of purification box 603 by the first positioning screw. Gradient density glass fiber filter cotton is provided on the inner side of purification plate 604. Activated carbon adsorption plate 605 is installed inside the other end of purification box 603 by the second positioning screw. Centrifugal fan 606 is fixedly installed on one side of the first mounting plate 2. The output end of centrifugal fan 606 is connected to the purification box 603 through a pipe. Centrifugal fan 606 is electrically connected to PLC control panel 9. When in use, when the spraying component 5 is started, PLC control panel 9 simultaneously starts centrifugal fan 606. Centrifugal fan 606 creates negative pressure in the purification box 603 and the suction hood 601 through the pipe, forcibly sucking the VOCs volatilized in the collection box 4 and the suspended paint mist into the suction hood 601. The linear array baffles on the inner side of the suction hood 601 can guide the airflow to flow in an orderly manner, so that the paint mist and VOCs mixture enters the purification box 603 through the air supply pipe 602. First, it passes through the purification plate 604 in the purification box 603. The gradient density glass fiber filter cotton (sparse outer layer and dense inner layer) on the inner side of the purification plate 604 can efficiently capture large particles of paint mist. After being intercepted, the paint mist adheres to the gradient density glass fiber filter cotton, completing the "preliminary treatment of paint mist". After the paint mist is removed, the exhaust gas continues to flow to the activated carbon adsorption plate 605 at the other end of the purification chamber 603. The porous structure of the activated carbon adsorbs VOCs molecules within the pores, achieving deep purification of VOCs. The purified exhaust gas that meets the standards is finally discharged through the centrifugal fan 606. The inner sides of the suction hood 601 and the air supply pipe 602 are coated with polytetrafluoroethylene, which can prevent paint mist from adhering to the pipe wall, reduce cleaning frequency, and lower maintenance costs.

[0020] Working Principle: First, based on the length of the shaft to be coated, the second motor 11 is started via the PLC control panel 9. The second motor 11 drives the first lead screw in the square slot 7 to rotate, causing the second mounting plate 3 connected to the first lead screw to slide along the worktable 1 until the clamping rod on one side of the second mounting plate 3 aligns with one end of the shaft. Then, one end of the shaft is placed into the three-jaw chuck of the first mounting plate 2, which clamps the shaft. Simultaneously, the PLC control panel 9 controls the clamping rod to adhere to the other end of the shaft for auxiliary fixation, thus positioning both ends of the shaft and preventing shaking during spraying. Next, the first motor 10 is started, driving the rotating disk on one side of the first mounting plate 2 to rotate, which in turn drives the three-jaw chuck to rotate synchronously with the shaft (the speed can be adjusted via the PLC control panel 9, usually 5~10 r / min), preparing for subsequent spraying. Then, the spraying component 5 automatically sprays the shaft, while the purification component 6 treats paint mist and VOCs to achieve environmentally friendly emissions. After spraying is complete, the shaft can be removed.
