[0013] A method for operating a leak-free and environmentally friendly paint spraying workshop, comprising the following steps: S1: Hang the parts that need to be painted in the placement unit, and the guide device will drive the parts into the coating unit and drying unit in turn; S2: The atomizing spray device will paint the parts in the spray chamber, and then the drying box will dry and shape the painted parts; S3: After each batch of parts is painted, the shovel mechanism will recycle the materials attached to the bottom of the spray chamber, and the absorption mechanism will also recycle the exhaust gas in the spray chamber; S4: After taking the dried parts, the electromagnetic plate will drive the scraping mechanism to start working and scrape away the materials attached to the hanging rod and the support rod.

[0014] The beneficial effects of the present invention are as follows: 1. The present invention sets a shoveling mechanism. After taking down the dried object, the electromagnet will generate magnetic force and attract the magnetic block 1, so that the telescopic spring 1 is stretched and the whole shoveling mechanism moves downward. In this process, the shovel blade will come into contact with the support rod 1 and the hanging rod, and scrape off the paint attached thereon. The reverse force generated by the scratch in this process will also compress the telescopic spring 2. In the subsequent recovery process, the telescopic spring 2 recovers and drives the shovel blade to collide with the impact column, so that the material that has just scratched the shovel blade is separated, thereby realizing self-cleaning.

[0015] 2. The present invention sets a spraying device.

[0016] 3. The present invention sets a shoveling mechanism. After a batch of parts are coated, the shovel plate shovels the materials on the inclined surface. As the moving plate moves, the distance between the magnetic column and the magnetic block 2 becomes farther, and the mutual magnetic force will decrease. The gravity of the slider 2 will make the slider 2 slide downward along the sliding groove and scrape the materials on the side of the shovel plate that is attached to the materials to the bottom of the shovel plate, so that they can be recovered from the gap at the bottom later.

[0017] 4. The present invention provides an absorption mechanism. As the rotating shaft 2 rotates, the scraping arm scrapes against the inner wall of the waste pipe, so that the impurity particles on the pipe wall are scraped off into the waste pipe, avoiding the accumulation of particles and clogging of the pipe due to long-term waste gas recovery.

[0032] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms.

The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0033] Example 1, using Figure 1-Figure 12 A leak-free and environmentally friendly paint spraying workshop and an operating method thereof according to one embodiment of the present invention are described as follows.

[0034] like Figure 1-Figure 2 As shown, a leak-free and environmentally friendly paint spraying workshop of the present invention comprises a guide device 1, the outer surface of the guide device 1 is evenly provided with support columns 2, the top of the support column 2 is fixedly connected to the outer surface of the guide device 1, the inner wall of the guide device 1 is slidably connected with a moving block 3, and the bottom of the moving block 3 is rotatably connected with a placement unit 4; A coating unit 6, which is used to coat the parts, and a dust collecting unit 5 is fixedly connected to the outer surface of the coating unit 6; A drying unit 7, which is used to heat and dry the painted parts; The coating unit 6 is located at the bottom of the guide device 1, and the drying unit 7 is located at the bottom of the guide device; When the present invention is working, the parts that need to be painted are hung in the placement unit 4, and then the guide device 1 will drive the parts to enter the coating unit 6 and the drying unit 7 in turn. The coating unit 6 will paint the parts, and the drying box 71 will dry and shape the painted parts.

[0035] like Figure 3 As shown, the placement unit 4 includes a rotating shaft 41, a gear 42 is fixedly connected to the outer surface of the rotating shaft 41, a support rod 43 is fixedly connected to the bottom of the rotating shaft 41, a hanging rod 44 is evenly arranged on the outer surface of the support rod 43, a support plate 45 is fixedly connected to the top of the support rod 43, a telescopic spring 46 is fixedly connected to the bottom of the support plate 45, and a shoveling mechanism 47 is fixedly connected to the bottom of the telescopic spring 46; like Figure 4 As shown, the shoveling mechanism 47 includes a frame plate 471, the inner wall of the frame plate 471 is fixedly connected with a sliding rod 473, the frame plate 471 is fixedly connected with a telescopic spring 2 474 near the sliding rod 473, the bottom of the telescopic spring 2 474 is fixedly connected with a slider 1 475, the outer surface of the slider 1 475 is fixedly connected with a scraper 476, and the bottom of the frame plate 471 is evenly provided with impact columns 477, and the top of the impact column 477 is fixedly connected to the bottom of the frame plate 471.

[0036] During the coating process, the sprayed material will also adhere to the support rod 43 and the hanging rod 44, and it will be difficult to remove after cyclic heating, which will affect the placement of subsequent parts. After taking down the dried objects, the electromagnet will generate magnetic force and attract the magnetic block 472, so that the telescopic spring 46 is stretched and the overall scraping mechanism 47 moves downward. In this process, the scraper 476 will come into contact with the support rod 43 and the hanging rod 44 and scrape off the paint adhered thereto. The reverse force generated by the scratches in this process will also compress the telescopic spring 474. In the subsequent recovery process, the telescopic spring 474 recovers and drives the scraper 476 to collide with the impact column 477, so that the material that has just scratched the scraper 476 is detached, thereby achieving self-cleaning.

[0037] The top of the rotating shaft 41 is rotatably connected to the bottom of the moving block 3, the top of the frame plate 471 is fixedly connected to the bottom of the telescopic spring 46, and the inner wall of the sliding block 475 is slidably connected to the outer surface of the sliding rod 473.

[0038] like Figure 11-Figure 12As shown, the drying unit 7 includes a drying box 71, the outer surface of the drying box 71 is fixedly connected to the end of the spray chamber 61 away from the magnetic block 66, a movable groove 72 is provided on the top of the drying box 71, an oven 73 is fixedly connected to the bottom of the drying box 71, an air inlet 74 is fixedly connected to the outer surface of the oven 73, a curtain 75 is rotatably connected to one end of the drying box 71, an outer box 76 is fixedly connected to the side of the oven 73 close to the curtain 75, an electromagnetic plate 78 is fixedly connected to the bottom of the outer box 76, an electric wire 79 is fixedly connected to the outer surface of the electromagnetic plate 78, an end of the electric wire 79 away from the electromagnetic plate 78 is fixedly connected to a power source 710, and a dirt storage plate 77 is fixedly connected to the inner wall of the outer box 76.

[0039] The oven 73 will heat the air and transmit it into the drying box 71 to heat and shape the parts therein. After taking the parts, the power supply 710 will energize the electromagnetic plate 78 through the wire 79, so that the electromagnetic plate generates magnetic force, thereby driving the shoveling mechanism 47 to start working.

[0040] The specific workflow is as follows: During operation, after taking down the dried object, the power supply 710 will energize the electromagnetic plate 78 through the wire 79, so that the electromagnetic plate generates magnetic force, and the electromagnet will generate magnetic force and attract the magnetic block 472, so that the telescopic spring 46 is stretched and the overall shoveling mechanism 47 moves downward. In this process, the scraper 476 will come into contact with the support rod 43 and the hanging rod 44, and scrape off the paint attached thereto. In this process, the reverse force generated by the scratching will also compress the telescopic spring 474. In the subsequent recovery process, the telescopic spring 474 recovers and drives the scraper 476 to collide with the impact column 477, so that the material that has just scratched the scraper 476 is detached.

[0041] Embodiment 2, use Figure 1-Figure 13 A leak-free and environmentally friendly paint spraying workshop and an operating method thereof according to one embodiment of the present invention are described as follows.

[0042] like Figure 5-Figure 6As shown, a leak-free and environmentally friendly paint spraying workshop of the present invention, on the basis of embodiment 1, the paint unit 6 includes a spraying bin 61, a movable groove 62 is arranged on the top of the spraying bin 61, a bottom block 63 is evenly arranged on the bottom of the spraying bin 61, the top of the bottom block 63 is fixedly connected to the bottom of the spraying bin 61, a feeding device 64 is fixedly connected to the outer surface of the spraying bin 61, a transmission pipe 65 is fixedly connected to the top of the feeding device 64, and an end of the transmission pipe 65 away from the feeding device 64 is fixedly connected to an atomizer A spraying device 69, magnetic blocks 66 are symmetrically arranged at both ends of the spraying bin 61, and the magnetic blocks 66 are located at the front of the spraying bin 61. A slope 67 is arranged at the bottom of the spraying bin 61. A shoveling mechanism 68 is fixedly connected to the bottom of the inner wall of the spraying bin 61.

A support rod 612 is fixedly connected to the top of the spraying bin 61, and a rack 613 is fixedly connected to the top of the support rod 612.

[0043] When the guide device 1 drives the parts to move, the gear 42 will come into contact with the rack 613, so that the gear 42 and the rotating shaft 41 rotate, thereby driving the parts hung on the hanging rod 44 to rotate, so that the material sprayed by the atomizing spray device 69 can be fully attached to the parts.

[0044] like Figure 7-Figure 8 As shown, the shoveling mechanism 68 includes a baffle 681, a servo motor 682 is fixedly connected to the inner wall of the spray chamber 61, a screw 683 is fixedly connected to the output end of the servo motor 682, a movable plate 684 is threadedly connected to the outer surface of the screw 683, a shovel plate 685 is fixedly connected to the outer surface of the movable plate 684, a sliding groove 686 is provided on the outer surface of the shovel plate 685, a sliding groove 686 is slidably connected to the outer surface of the sliding groove 686, a slider 687 is slidably connected to the outer surface of the slider 687, a scratch plate 688 is fixedly connected to the outer surface of the slider 687, and a magnetic column 689 is fixedly connected to the top of the slider 687.

[0045] After a batch of parts are painted, the servo motor 1 682 will drive the screw 683 to rotate, thereby moving the movable plate 684 and causing the shovel plate 685 to shovel the material on the inclined surface 67. As the movable plate 684 moves, the distance between the magnetic column 689 and the magnetic block 2 66 becomes farther, and the magnetic force between them will decrease. The gravity of the slider 2 687 will cause the slider 2 687 to slide downward along the sliding groove 686, and scrape the material on the side of the shovel plate 685 that is attached to the material to the bottom of the shovel plate 685, so that it can be recovered from the gap at the bottom later.

[0049] After the absorption device 610 absorbs the exhaust gas in the spray chamber 61 into the waste pipe 52, the servo motor 534 will drive the rotating shaft 535 to rotate, so that the fan blades 536 generate suction, so that the exhaust gas further enters the subsequent storage box 54, which is convenient for subsequent purification and reuse. The exhaust gas in the storage box 54 will be pre-treated to remove solid particles, paint mist and other impurities. Common methods include filtering and spraying. Finally, the pre-treated exhaust gas is recycled and treated by adsorption, condensation, catalytic combustion, etc., so as to achieve the recovery or harmless treatment of substances such as volatile organic compounds in the exhaust gas. However, some particulate matter in the exhaust gas will adhere to the wall of the waste pipe 52. As the rotating shaft 535 rotates, the scratch arm 537 will scratch the inner wall of the waste pipe 52, so that the impurity particles on the wall are scraped into the waste pipe 52, so as to avoid the accumulation of particulate matter and blockage of the pipeline due to long-term exhaust gas recovery.

[0050] The outer surface of the support frame 51 is fixedly connected to the outer surface of the spray chamber 61 , the bottom of the dust suction pipe 531 is fixedly connected to the inner wall of the waste pipe 52 , and the outer surface of the waste pipe 52 is fixedly connected to one end of the air pipe 611 away from the absorption device 610 .
