Technical Field
[0001] This utility model relates to the field of wood product processing technology, specifically to a painting device for wood product processing. Background Technology
[0002] Wood processing is a production process that transforms logs or wood panels into finished or semi-finished products such as furniture, doors and windows, flooring, and decorations through multiple processes including cutting, sanding, carving, splicing, and painting. In this process, craftsmen use exquisite techniques and advanced machinery to give wood new forms and uses, creating beautiful and practical wood products that meet people's living and aesthetic needs.
[0003] In wood processing, spray painting equipment is needed to coat logs. Although existing technology meets the needs of users to a certain extent, there are still some shortcomings in its use. The specific problems are as follows: volatile organic compounds (VOCs), formaldehyde, benzene, and other harmful substances generated during the spraying process cannot be effectively treated and are directly emitted into the air, posing a potential threat to the health of workers, such as causing respiratory diseases and nervous system damage. The emission of these harmful substances also pollutes the environment, exacerbating air pollution problems, such as forming photochemical smog and haze, affecting air quality and ecological balance. In addition, the lack of air purification function will also affect the environmental quality of the spray painting site, increasing the difficulty and cost of cleaning and maintenance.
[0004] To address the aforementioned issues, we have made improvements and proposed a painting device for wood product processing. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a painting device for wood product processing, including a base plate, a spray box fixedly connected to the top of the base plate, a purification box fixedly connected to the top of the spray box, a duct fan fixedly connected to the right side of the inner cavity of the purification box, two sets of mounting brackets fixedly connected to the top and bottom of the inner cavity of the purification box, and activated carbon adsorption mesh clamped into the inner cavity of both sets of mounting brackets, an air inlet pipe connected to the left side of the purification box, the bottom of the air inlet pipe connected to the left side of the top of the inner cavity of the spray box, the output end of the duct fan connected to the right side of the top of the inner cavity of the spray box, and a ventilation mesh embedded in the top of the left side of the spray box.
[0006] Preferably, a second cylinder is movably connected to the left side of the inner cavity of the spray box via a rotating shaft, and a first cylinder is movably connected to the right side of the inner cavity of the spray box via a rotating shaft. The output ends of the first cylinder and the second cylinder are both fixedly connected to clamps, and anti-slip pads are adhered to the inner side of the clamps.
[0007] Preferably, a stepper motor for driving the first cylinder to rotate is fixedly installed on the right side of the spray box. The output end of the stepper motor extends into the inner cavity of the spray box and is fixedly connected to the right side of the first cylinder. A partition is fixedly connected to the bottom of the inner cavity of the spray box. A material discharge groove is opened through the middle of the inner surface of the partition. A collection box is placed at the middle of the bottom of the inner cavity of the spray box and below the partition.
[0008] Preferably, a corrugated pipe is connected to the left side of the inner cavity of the spray box, and a spraying mechanism is provided at the top of the inner cavity of the spray box.
[0009] Preferably, a servo motor is fixedly connected to the bottom left side of the spray box, and a screw is fixedly connected to the output end of the servo motor. Screw sleeves are threadedly connected to both sides of the screw surface, and a scraper is engaged at the bottom of the screw sleeve. The bottom of the scraper contacts the top of the partition.
[0010] Preferably, the inner wall of the spray box has grooves on both the left and right sides, and the back side of the scraper is fixedly connected to a slider, which is slidably connected to the inner cavity of the groove.
[0011] Compared with the prior art, the present invention provides a painting device for wood product processing, which has the following beneficial effects:
[0012] 1. This wood product processing spray painting device uses a suction force generated at the input end of a duct fan to draw air from the inner cavity of the spray box into the inner cavity of the purification box through an air inlet pipe. Activated carbon adsorption mesh is used to retain and adsorb impurities and harmful substances in the air, purifying the air inside the spray box. Then, the suction force generated at the input end of the duct fan draws in the purified air, and the output end of the duct fan sends the air back into the inner cavity of the spray box for drying the sprayed workpiece. This cycle effectively purifies the air inside the spray box.
[0013] 2. This wood product processing spray painting device extends inward from the output ends of the first and second cylinders, driving the clamping plate to move inward. The clamping plate can limit the workpiece, improving the stability during the spraying process. By setting a stepper motor, the workpiece can be flipped, improving the uniformity of spraying. During the rotation of the screw, the screw sleeve moves inward using the thread action. The screw sleeve drives the scraper to move inward, scraping the paint on the top of the partition inward. The paint falls into the inner cavity of the collection box through the drop chute for collection, facilitating secondary use. By setting a sliding groove and a slider, the stability of the screw sleeve during horizontal movement can be effectively improved. By setting a retainer, the activated carbon adsorption screen can be disassembled for cleaning or replacement. Attached Figure Description

[0022] Through the above technical solution, the air in the inner cavity of the spray box 2 is drawn into the inner cavity of the purification box 3 through the air inlet pipe 11 by the suction generated at the input end of the induced flow fan 14. The activated carbon adsorption net 13 is used to retain and adsorb impurities and harmful substances mixed in the air, thus purifying the air in the inner cavity of the spray box 2. Then, the suction generated at the input end of the induced flow fan 14 draws in the purified air, and the output end of the induced flow fan 14 sends the air back into the inner cavity of the spray box 2 to air dry the sprayed workpiece. At the same time, the air in the inner cavity of the spray box 2 is effectively purified by repeated cycles. By setting the bracket 12, the activated carbon adsorption net 13 can be disassembled for cleaning or replacement.
[0023] Specifically, a second cylinder 6 is movably connected to the left side of the inner cavity of the spray box 2 via a rotating shaft, and a first cylinder 5 is movably connected to the right side of the inner cavity of the spray box 2 via a rotating shaft. Both the output ends of the first cylinder 5 and the second cylinder 6 are fixedly connected to clamping plates 7, and anti-slip pads are adhered to the inner side of the clamping plates 7. A stepper motor 4 for driving the first cylinder 5 is fixedly installed on the right side of the spray box 2. The output end of the stepper motor 4 extends into the inner cavity of the spray box 2, and is fixedly connected to the right side of the first cylinder 5. A partition 15 is fixedly connected to the bottom of the inner cavity of the spray box 2, and the middle of the inner surface of the partition 15 extends through... A material discharge chute 16 is provided through the spray box 2. A collection box 17 is placed at the middle of the bottom of the spray box 2 and below the partition 15. A servo motor 18 is fixedly connected to the bottom left side of the spray box 2. A screw 19 is fixedly connected to the output end of the servo motor 18. Screw sleeves 20 are threadedly connected to both sides of the surface of the screw 19. A scraper 21 is snapped into the bottom of the screw sleeve 20. The bottom of the scraper 21 contacts the top of the partition 15. Slide grooves 22 are provided on both sides of the back side of the inner wall of the spray box 2. A slider 23 is fixedly connected to the back side of the scraper 21. The back side of the slider 23 is slidably connected to the inner cavity of the slide groove 22.
[0024] Through the above technical solution, the output ends of the first cylinder 5 and the second cylinder 6 extend inward and drive the clamping plate 7 to move inward. The clamping plate 7 can limit the workpiece and improve the stability during the spraying process. By setting the stepper motor 4, the workpiece can be flipped, which improves the uniformity of the spraying. During the rotation of the screw 19, the screw sleeve 20 is driven to move inward by the action of the thread. The screw sleeve 20 drives the scraper 21 to move inward, scraping the paint on the top of the partition 15 inward. The paint falls into the inner cavity of the collection box 17 through the drop groove 16 for collection, which is convenient for secondary use. By setting the sliding groove 22 and the slider 23, the stability of the screw sleeve 20 during horizontal movement can be effectively improved.
[0025] In operation, the output ends of the first cylinder 5 and the second cylinder 6 extend inward and drive the clamping plate 7 to move inward. The clamping plate 7 limits the workpiece, and the spraying mechanism 10 sprays the workpiece. After spraying, the input end of the exhaust fan 14 generates suction to draw air from the inner cavity of the spray box 2 into the inner cavity of the purification box 3 through the air inlet pipe 11. The activated carbon adsorption net 13 retains and adsorbs impurities and harmful substances in the air, purifying the air in the inner cavity of the spray box 2. Then, the input end of the exhaust fan 14 generates suction to draw in the purified air, and the output end of the exhaust fan 14 sends the air back to the spray box. Inside the cavity of spray box 2, the sprayed workpiece is air-dried, and the air inside the cavity of spray box 2 is effectively purified through repeated cycles. At the same time, the output end of servo motor 18 drives screw 19 to rotate. During the rotation of screw 19, the screw thread drives screw sleeve 20 to move inward. Screw sleeve 20 drives scraper 21 to move inward, scraping the paint on the top of partition 15 inward. The paint falls into the cavity of collection box 17 through drop trough 16 for collection, which is convenient for secondary use. (The above is the working process of the whole device.
