Description

Technical Field

[0001] This utility model relates to the field of processing equipment, specifically a spray booth for steel drums. Background Technology

[0002] Spray painting is a surface treatment technology that uses a spray gun to atomize paint and apply it evenly to the surface of an object to achieve protection, decoration, or to impart specific functions (such as insulation and wear resistance). Its core is to form a continuous and uniform coating by controlling the atomization, adhesion, and curing process of the paint.

[0003] Chinese Patent No. CN202323376397.8 discloses a spray booth, including a box body, a spray booth mounted on top of the box body, a plurality of spray nozzles extending into the box body, and sound insulation material lining the inner wall of the box body. A waste collection mechanism is installed inside the box body, comprising a scraper fitted against the inner wall of the box body, a drive component mounted inside the box body to drive the scraper to move up and down, and a waste discharge structure located at the lower part of the box body and communicating with the outside of the box body. An exhaust gas collection mechanism is installed on one side of the box body and communicating with the top of the box body; the exhaust gas collection mechanism includes an exhaust fan and a water tank located below the exhaust gas collection mechanism.

[0004] As can be seen from the above, the spray booth can effectively isolate the noise inside the booth, and the waste collection mechanism can quickly and conveniently scrape away the waste on the inner wall of the spray booth, ensuring the painting effect. However, this case still has the following shortcomings: Firstly, the fixed position of the spray nozzle cannot adapt to steel drums of different heights and diameters, resulting in uneven painting, especially with missed areas at the top and bottom of the drums. Secondly, the lack of precise positioning during the transportation of steel drums makes it easy for the paint to shift due to shaking, affecting the appearance quality. Third, paint splattering leads to significant waste, and the lack of an effective paint recycling system increases production costs.

[0005] Therefore, a spray booth for steel drums is proposed to address the above problems. Summary of the Invention

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0018] Please see Figures 1-5As shown, a spray booth for steel drums includes a conveyor belt 1. A spraying assembly 2 is provided on one side of the conveyor belt 1. The spraying assembly 2 includes a spraying component 3 and a conveying component 4. The spraying component 3 includes a fixed frame 21. A translation frame 26 is slidably mounted on the fixed frame 21. A first servo motor 22 is fixedly mounted on one side of the translation frame 26. A first gear 23 is fixedly mounted on the output end of the first servo motor 22. A first rack 24 is meshed with one side of the first gear 23. The first rack 24 is fixedly mounted on one side of the fixed frame 21. A lifting frame 29 is slidably mounted on the translation frame 26. An annular conveying channel 31 is fixedly mounted at the bottom of the lifting frame 29. A plurality of movable atomizing nozzles 32 are sequentially fixedly mounted on the annular conveying channel 31. During operation, based on the diameter of the steel drum, the first servo motor 22 drives the first gear 23 to rotate along the first rack 24, causing the translation frame 26 to slide laterally on the fixed frame 21, adjusting the horizontal distance between the movable atomizing nozzle 32 and the steel drum; the annular conveying channel 31 conveys paint to the movable atomizing nozzle 32, and multiple movable atomizing nozzles 32 spray around the steel drum to ensure uniform side painting.

[0019] Furthermore, the paint spraying assembly 2 also includes a second servo motor 27, which is fixedly installed on one side of the lifting frame 29. A second gear 25 is fixedly installed at the output end of the second servo motor 27. A second rack 28 is meshed with one side of the second gear 25. The second rack 28 is fixedly installed on one side of the translation frame 26. During operation, based on the height of the steel drum, the second servo motor 27 drives the second gear 25 to rotate along the second rack 28, causing the lifting frame 29 to slide vertically on the translation frame 26, adjusting the height of the movable atomizing nozzle 32 to ensure that the top and bottom of the steel drum can be effectively painted, avoiding missed spraying.

[0020] Furthermore, the conveying component 4 includes a base 41, a stepper motor 43 is fixedly installed on one side of the top of the base 41, a drive pulley 44 is fixedly installed at the output end of the stepper motor 43, a drive belt 45 is drivenly connected to the outer surface of the drive pulley 44, a plurality of push rods 47 are fixedly installed on the outer surface of the drive belt 45, a driven pulley 46 is drivenly connected to one side of the drive belt 45, and the driven pulley 46 is rotatably installed on the top of the base 41; During operation, the stepper motor 43 drives the active pulley 44 to rotate, which in turn drives the driven pulley 46 to rotate synchronously via the transmission belt 45. The push rod 47 moves with the transmission belt 45, pushing the steel drums conveyed by the transmission belt 1 to the support rod 401 one by one, ensuring that the steel drums enter the painting area smoothly at a preset speed and avoiding shaking during the conveying process.

[0021] Furthermore, the conveyor 4 also includes a gathering bucket 42, which is fixedly installed on the top of the base 41, and a drop trough 402 is provided in the middle of the gathering bucket 42. During operation, the steel drum moves under the action of the push rod 47 to center the steel drum and prevent it from shifting and affecting the painting accuracy; during the painting process, the excess paint splashed will slide down the inner wall of the gathering hopper 42 to the drop trough 402.

[0022] Furthermore, multiple fixed atomizing nozzles 48 are fixedly installed on the top of the gathering hopper 42, and two support rods 401 are fixedly installed on the top of the base 41, with the support rods 401 flush with the top of the transmission belt 45. During operation, the fixed atomizing nozzle 48 applies additional paint to the bottom and top edges of the steel drum that has passed through the gathering hopper 42, eliminating paint dead spots; the support rod 401 is flush with the transmission belt 45 to ensure that the steel drum is at a consistent height during transportation, avoiding uneven paint application due to tilting.

[0023] Furthermore, a collection hopper 49 is placed on one side of the bottom of the base 41, the collection hopper 49 is located directly below the drop trough 402, two fixing brackets 21 are fixedly installed on the top of the base 41, and a protective cover 403 is fixedly installed on the top of the base 41. During operation, excess paint in the drop trough 402 flows into the collection hopper 49 for recycling and reuse, reducing waste; the protective cover 403 blocks paint splashing, protecting the working environment, while the fixing frame 21 provides stable support for the painted parts 3.

[0024] Working principle: The steel drum is conveyed to the support rod 401 via the conveyor belt 1. The stepper motor 43 drives the drive pulley 44 to rotate, which in turn drives the push rod 47 via the transmission belt 45 to smoothly push the steel drum to the top of the collecting hopper 42. The fixed atomizing nozzle 48 simultaneously pre-sprays paint on the bottom edge of the steel drum. According to the height of the steel drum, the second servo motor 27 drives the lifting frame 29 to rise and fall, adjusting the height of the movable atomizing nozzle 32. According to the diameter of the steel drum, the first servo motor 22 drives the translation frame 26 to move laterally, adjusting the horizontal distance of the movable atomizing nozzle 32. The annular conveying channel 31 conveys paint to the movable atomizing nozzle 32, achieving uniform spraying around the drum. Excess paint is collected in the collecting hopper 42 and flows into the drop trough 402, then into the collection hopper 49 for recycling. The protective cover 403 prevents paint from splashing out, completing the efficient and precise painting of the steel drum.
