[0002] A paint spraying workshop is a professional production space integrating multiple functions. It has a reasonable layout. The central spraying area is equipped with advanced automatic and manual spraying equipment to meet the spraying requirements of different workpieces; the pre-treatment area on one side performs surface treatment on the workpieces to enhance the adhesion of the paint; the adjacent drying area can quickly dry and cure the paint. At the same time, the workshop is also equipped with perfect environmental protection facilities. The waste gas treatment system can efficiently purify organic waste gas, the waste water treatment system realizes the recycling of water resources, and together with comprehensive leak-free protection measures such as ground protection, equipment sealing and leakage detection systems, etc., it not only ensures the environmental protection of the production process, but also can effectively prevent paint leakage, ensuring safe, efficient and green production.

[0018] An operation method for a leak-free and environmentally friendly paint spraying workshop includes the following steps:

[0019] S1: Hang the parts that need paint in the placement unit, and the guiding device will drive the parts to enter the paint unit and the drying unit in sequence;

[0020] S2: The atomizing spraying device will paint the parts in the spraying chamber, and then the drying box will dry and shape the painted parts;

[0021] S3: After each batch of parts is painted, the shoveling mechanism will recover the materials attached to the bottom of the spraying chamber, and the absorption mechanism will also recover the waste gas in the spraying chamber;

[0022] S4: After taking out the dried parts, the electromagnet plate will drive the shoveling mechanism to start working to remove the materials attached to the hanging rod and the first support rod.

[0023] The beneficial effects of the present invention are as follows:

[0024] 1. By setting up the shoveling mechanism, after taking down the dried object, the electromagnet will generate magnetic force and attract the first magnet, so that the first telescopic spring is stretched, and the whole shoveling mechanism moves downward. In this process, the shovel blade will come into contact with the first support rod and the hanging rod, and scrape off the paint adhering to them. The reverse force generated by the scraping in this process will also compress the second telescopic spring. In the subsequent recovery process, the second telescopic spring recovers and drives the shovel blade to collide with the impact column, so that the materials just scraped on the shovel blade are separated, thus realizing self-cleaning.

[0025] 2. In the present invention, by providing a spraying device, during the process of the guiding device driving the part to move, the gear will come into contact with the rack, causing the gear and the first rotating shaft to rotate. Subsequently, the part hanging on the hanging rod will be driven to rotate, enabling the material ejected by the atomizing spraying device to fully adhere to the part.

[0026] 3. In the present invention, by providing a shoveling mechanism, after a batch of parts are coated, the shovel plate shovels the material on the inclined plane. As the moving plate moves, the distance between the magnetic column and the second magnetic block becomes farther, and the magnetic force between them decreases. The gravity of the second slider will cause the second slider to slide downward along the sliding groove, and scrape the material on the surface of the shovel plate that adheres to the material to the bottom of the shovel plate, facilitating subsequent recovery from the notch at the bottom.

[0027] 4. In the present invention, by providing an absorption mechanism, as the second rotating shaft rotates, the scraping arm will scrape against the inner wall of the waste pipe, causing the impurity particles on the pipe wall to be scraped into the waste pipe, preventing the accumulation of particles from clogging the pipe due to the long-term recovery of waste gas.

Detailed implementation manners

[0042] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners. The embodiments of the present invention are given for the purpose of illustration and description, and are not exhaustive or limited to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific purposes.

[0043] Embodiment 1, usage Figures 1-12 A leak-free and environmentally friendly paint spraying workshop and its operation method according to an embodiment of the present invention will be described as follows.

[0044] As Figures 1-2As shown in the figure, an environmentally friendly paint spraying workshop without leakage of the present invention includes a guiding device 1. The outer surface of the guiding 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 guiding device 1. A moving block 3 is slidably connected to the inner wall of the guiding device 1. A placing unit 4 is rotatably connected to the bottom of the moving block 3;

[0045] A paint unit 6, which is used to paint parts. A dust suction unit 5 is fixedly connected to the outer surface of the paint unit 6;

[0046] A drying unit 7, which is used to heat and dry the painted parts;

[0047] The paint unit 6 is located at the bottom of the guiding device 1, and the drying unit 7 is located at the bottom of the guiding device 1;

[0048] When the present invention works, the parts to be painted are hung in the placing unit 4. Then, the guiding device 1 will drive the parts to enter the paint unit 6 and the drying unit 7 in sequence. The paint unit 6 will paint the parts, and the drying oven 71 will dry and shape the painted parts.

[0049] As Figure 3 shown, the placing unit 4 includes a first rotating shaft 41. A gear 42 is fixedly connected to the outer surface of the first rotating shaft 41. A first support rod 43 is fixedly connected to the bottom of the first rotating shaft 41. Hanging rods 44 are evenly arranged on the outer surface of the first support rod 43. A first support plate 45 is fixedly connected to the top of the first support rod 43. A first telescopic spring 46 is fixedly connected to the bottom of the first support plate 45. A material shoveling mechanism 47 is fixedly connected to the bottom of the first telescopic spring 46;

[0050] As Figure 4 shown, the material shoveling mechanism 47 includes a frame plate 471. A sliding rod 473 is fixedly connected to the inner wall of the frame plate 471. A second telescopic spring 474 is fixedly connected to the frame plate 471 near the sliding rod 473. A first slider 475 is fixedly connected to the bottom of the second telescopic spring 474. A shovel 476 is fixedly connected to the outer surface of the first slider 475. Impact columns 477 are evenly arranged at the bottom of the frame plate 471. The top of the impact column 477 is fixedly connected to the bottom of the frame plate 471.

[0051] During the coating process, the ejected material will also adhere to the first support rod 43 and the hanging rod 44. After cyclic heating, it will be difficult to remove, affecting the placement of subsequent parts. After removing the dried object, the electromagnet will generate magnetic force and attract the first magnetic block 472, causing the first telescopic spring 46 to be stretched and the overall material shoveling mechanism 47 to move downward. During this process, the shovel blade 476 will come into contact with the first support rod 43 and the hanging rod 44 and scrape off the coating adhering to them. The reverse force generated during this scraping process will also compress the second telescopic spring 474. During the subsequent restoration process, the second telescopic spring 474 will restore and drive the shovel blade 476 to collide with the impact column 477, causing the material just scraped on the shovel blade 476 to fall off, thus achieving self-cleaning.

[0052] The top of the first 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 first telescopic spring 46. The inner wall of the first slider 475 is slidably connected to the outer surface of the sliding rod 473.

[0053] As Figures 11-12 As shown in the figure, the drying unit 7 includes a drying box 71. The outer surface of the drying box 71 is fixedly connected to one end of the spraying chamber 61 away from the second magnetic block 66. A second moving groove 72 is provided at 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 electromagnet plate 78 is fixedly connected to the bottom of the outer box 76. A wire 79 is fixedly connected to the outer surface of the electromagnet plate 78. One end of the wire 79 away from the electromagnet plate 78 is fixedly connected to a power supply 710. A dirt storage plate 77 is fixedly connected to the inner wall of the outer box 76.

[0054] The oven 73 will heat the air and transfer it into the drying box 71 to heat and shape the parts inside. After taking out the parts, the power supply 710 will energize the electromagnet plate 78 through the wire 79, causing the electromagnet plate to generate magnetic force and driving the material shoveling mechanism 47 to start working.

[0055] The specific working process is as follows:

[0056] During operation, after removing the dried object, the power supply 710 will energize the electromagnetic plate 78 through the wire 79, causing the electromagnetic plate to generate magnetic force. The electromagnetic magnet will generate magnetic force and attract the first magnetic block 472, stretching the first telescopic spring 46 and moving the overall material shoveling mechanism 47 downward. During this process, the shovel blade 476 will come into contact with the first support rod 43 and the hanging rod 44, scraping off the paint adhering to them. The reverse force generated during this scraping process will also compress the second telescopic spring 474. During the subsequent restoration process, the second telescopic spring 474 will restore and drive the shovel blade 476 to collide with the impact column 477, causing the material that was just scraped onto the shovel blade 476 to fall off.

[0057] Embodiment 2, use Figures 1-13 A leak-free and environmentally friendly paint spraying workshop and its operation method according to an embodiment of the present invention will be described as follows.

[0058] As Figures 5-6 As shown, in 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 chamber 61. A first moving groove 62 is provided at the top of the spraying chamber 61. Bottom blocks 63 are evenly arranged at the bottom of the spraying chamber 61, and the top of the bottom blocks 63 is fixedly connected to the bottom of the spraying chamber 61. A replenishing device 64 is fixedly connected to the outer surface of the spraying chamber 61. A transmission pipe 65 is fixedly connected to the top of the replenishing device 64. One end of the transmission pipe 65 away from the replenishing device 64 is fixedly connected to an atomizing spraying device 69. Second magnetic blocks 66 are symmetrically arranged at both ends of the spraying chamber 61. The second magnetic blocks 66 are located on the front side of the spraying chamber 61. An inclined surface 67 is provided at the bottom of the spraying chamber 61. A shoveling mechanism 68 is fixedly connected to the bottom inner wall of the spraying chamber 61. An absorption device 610 is fixedly connected to the inner wall of the spraying chamber 61. An air pipe 611 is fixedly connected to the outer surface of the absorption device 610. A second support rod 612 is fixedly connected to the top of the spraying chamber 61. A rack 613 is fixedly connected to the top of the second support rod 612.

[0059] During the process of the guiding device 1 driving the part to move, the gear 42 will come into contact with the rack 613, causing the gear 42 and the first rotating shaft 41 to rotate, and then driving the part hanging on the hanging rod 44 to rotate, so that the material sprayed by the atomizing spraying device 69 can be fully adhered to the part.

[0060] As Figures 7-8As shown, the shoveling mechanism 68 includes a baffle 681. A servo motor 682 is fixedly connected to the inner wall of the spraying bin 61. The output end of the servo motor 682 is fixedly connected to a lead screw 683. A moving plate 684 is threadedly connected to the outer surface of the lead screw 683. A shovel plate 685 is fixedly connected to the outer surface of the moving plate 684. A sliding groove 686 is provided on the outer surface of the shovel plate 685. A second slider 687 is slidably connected to the outer surface of the sliding groove 686. A scraping plate 688 is fixedly connected to the outer surface of the second slider 687. A magnetic column 689 is fixedly connected to the top of the second slider 687.

[0061] After a batch of parts are coated, the servo motor 682 drives the lead screw 683 to rotate, thereby moving the moving plate 684 and causing the shovel plate 685 to shovel the material on the inclined surface 67. As the moving plate 684 moves, the distance between the magnetic column 689 and the second magnet 66 becomes farther, and the mutual magnetic force decreases. The gravity of the second slider 687 causes the second slider 687 to slide downward along the sliding groove 686, and scrapes the material on the material-adhering side of the shovel plate 685 to the bottom of the shovel plate 685, facilitating subsequent recovery from the bottom notch.

[0062] Both ends of the baffle 681 are fixedly connected to the inner wall of the spraying bin 61. The outer surface of the scraping plate 688 is in contact with one side of the shovel plate 685.

[0063] As Figure 9 shown, the dust suction unit 5 includes a support frame 51. A waste pipe 52 is fixedly connected to the outer surface of the support frame 51. An absorption mechanism 53 is fixedly connected to the inner wall of the waste pipe 52. A storage box 54 is fixedly connected to the top of the absorption mechanism 53.

[0064] As Figure 10 shown, the absorption mechanism 53 includes a dust suction pipe 531. A third support rod 532 is fixedly connected to the inner wall of the storage box 54. The bottom of the third support rod 532 is fixedly connected to a housing 533. A servo motor 534 is fixedly connected to the inner wall of the housing 533. The output end of the servo motor 534 is fixedly connected to a second rotating shaft 535. A fan blade 536 is fixedly connected to the bottom of the second rotating shaft 535. A scraping arm 537 is fixedly connected to the outer surface of the second rotating shaft 535.

[0065] After the absorption device 610 absorbs the waste gas in the spraying chamber 61 into the waste pipe 52, the second servo motor 534 drives the second rotating shaft 535 to rotate, so that the fan blade 536 generates suction, enabling the waste gas to further enter the subsequent storage box 54, facilitating subsequent purification and reuse. The waste gas in the storage box 54 will be pretreated to remove impurities such as solid particles and paint mist. Common methods include filtration and spraying. Finally, methods such as adsorption, condensation, and catalytic combustion are used to recover and process the pretreated waste gas, realizing the recovery or harmless treatment of substances such as volatile organic compounds in the waste gas. However, some particulate matter in the waste gas will adhere to the inner wall of the waste pipe 52. As the second rotating shaft 535 rotates, the scraping arm 537 will scrape against the inner wall of the waste pipe 52, causing the impurity particulate matter on the pipe wall to fall into the waste pipe 52, preventing the blockage of the pipeline due to the accumulation of particulate matter caused by the long-term recovery of waste gas.

[0066] The outer surface of the support frame 51 is fixedly connected to the outer surface of the spraying chamber 61. The bottom of the dust suction pipe 531 is fixedly connected to the inner wall of the waste pipe 52. 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.

[0067] An operation method for a leak-free and environmentally friendly paint spraying workshop includes the following steps:

[0068] S1: Hang the parts that need paint in the placement unit 4, and the guiding device 1 will drive the parts to enter the paint unit 6 and the drying unit 7 in sequence;

[0069] S2: The atomizing spraying device 69 will apply paint to the parts in the spraying chamber 61, and then the drying box 71 will dry and shape the painted parts;

[0070] S3: After each batch of parts is painted, the shoveling mechanism 68 will recover the materials attached to the bottom of the spraying chamber 61, and the absorption mechanism 53 will also recover the waste gas in the spraying chamber 61;

[0071] S4: After taking the dried parts, the electromagnetic plate 78 will drive the shoveling mechanism 47 to start working to remove the materials attached to the hanging rod 44 and the first support rod 43.

[0072] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present invention.
