Description

Technical Field

[0001] This application relates to the technical field of spray painting equipment, and in particular to a metal spray painting booth structure. Background Technology

[0002] In conventional metal processing, finished metal workpieces often require painting. Painting the surface of metal workpieces is a method to protect metal from oxidation and corrosion. It is an important means of metal corrosion protection, as the paint on the surface of the metal workpiece can act as a barrier to inhibit the intrusion of corrosive media, reducing damage to the metal workpiece and minimizing or deteriorating performance and condition.

[0003] The most common method for painting metal surfaces is manual spraying, which suffers from high labor intensity, low efficiency, and delays the overall process. In some related technologies, the painting operation is carried out on metal workpieces in a metal spray booth.

[0004] A metal spray painting booth is a sealed room equipped with a robotic spray painting arm that can spray paint and color metal workpieces. The booth also features an air filtration system that collects paint mist and organic waste gases generated during spray painting operations, then adsorbs and filters these gases before ensuring they meet emission standards.

[0005] However, during the painting process, the painting robot will cause some paint mist and organic waste gas to diffuse into the metal spray booth, which can easily damage the respiratory system and skin of the workers and affect their health. Summary of the Invention

[0006] In order to improve the situation of paint mist and organic waste gas dispersing into the metal spray booth, this application provides a metal spray booth structure.

[0007] This application provides a metal spray booth structure, which adopts the following technical solution: A metal spray booth structure, comprising: Main body of the spray booth; A support assembly, comprising a support frame disposed within the main body of the paint booth; A covering assembly, the covering assembly including a cover cloth disposed around the side of a support frame; A painting assembly is mounted on the support frame and located within the space enclosed by the cover cloth. The painting assembly is used to paint the workpiece. An exhaust gas collection and treatment device is used to adsorb the gas at the bottom of the paint booth body and purify the adsorbed gas.

[0008] By adopting the above technical solution, a tarpaulin is placed around the support frame, and the painting assembly sprays paint the workpiece within the space enclosed by the tarpaulin, which reduces the dispersion of paint mist and organic waste gas to the outside of the tarpaulin. After the workpiece is painted, the exhaust gas collection and treatment equipment adsorbs the gas at the bottom of the paint booth, causing the paint mist and organic waste gas inside the tarpaulin to be adsorbed into the exhaust gas collection and treatment equipment. The exhaust gas collection and treatment equipment then purifies the paint mist and organic waste gas to achieve compliant emissions.

[0009] Optionally, the covering assembly further includes: A first linear slide is mounted on the support frame; A traction block is connected to the moving end of the first linear slide, which can drive the traction block to move up and down; the top end of the cover is connected to the top end of the support frame, and the bottom end of the cover is connected to the traction block.

[0010] By adopting the above technical solution, when the first linear slide is activated, it can drive the traction block to move up and down. The traction block drives the bottom end of the cover cloth to move up and down, thereby adjusting the coverage area of ​​the cover cloth and controlling the dispersion of paint mist and organic waste gas. For work at greater heights, the traction block driving the bottom end of the cover cloth to move up and down facilitates moving the workpiece into or out of the cover cloth.

[0011] Optionally, the support component further includes: The second linear slide is located at the top of the interior of the spray booth body, and the top of the support frame is located at the moving end of the second linear slide. The second linear slide is used to drive the support frame to move in the horizontal direction. The roller is rotatably mounted at the bottom end of the support frame and abuts against the inner bottom wall of the paint booth.

[0012] By adopting the above technical solution, when the second linear slide is activated, it can drive the support frame to move horizontally. The support frame can then drive the painting assembly to move, thereby sequentially painting the workpieces inside the paint booth. The rollers roll as the support frame moves, providing support to the support frame.

[0013] Optionally, the painting assembly includes: A support rod is disposed at the top of the support frame and is vertically arranged. A support tube, which is slidably connected to the support rod; A drive source is provided, which is used to drive the support tube to move vertically; A paint spraying end is disposed at the bottom end of the support tube and is used to spray paint.

[0014] By adopting the above technical solution, when the drive source is started, the support tube can be moved in the vertical direction, thereby adjusting the distance between the paint spraying end and the workpiece, and thus adjusting the paint thickness on the workpiece.

[0015] Optionally, the paint spraying end includes: A sliding slide table, wherein the sliding slide table is disposed at the bottom end of the support tube; A support block is provided at the moving end of the sliding table, and the sliding table can drive the support block to move in the horizontal direction; A paint spray nozzle is mounted on the support block.

[0016] By adopting the above technical solution, when the sliding slide is started, the sliding slide drives the support block to move, and the support block drives the paint spray nozzle to move, thereby spraying paint on the surface of the workpiece.

[0017] Optionally, the paint spraying end also includes a movable component, and multiple movable components are arranged side by side on the support block; The paint spray nozzle is disposed at the moving end of the moving component, and the moving component is used to drive the paint spray nozzle closer to or away from the workpiece.

[0018] By adopting the above technical solution, when the moving part is activated, it can drive the paint spray nozzles closer to or further away from the workpiece. Since the top walls of some workpieces are not coplanar, the moving part can adjust the height of multiple paint spray nozzles to adapt to the shape of the top wall of the workpiece, so as to maintain the same paint thickness on the top walls of different heights of the workpiece.

[0019] Optionally, the support tube is provided with a covering assembly, the covering assembly comprising: A support frame is disposed on the support tube; A covering cloth is disposed on the supporting frame and covers the periphery of the paint spraying end. The covering cloth is located within the space enclosed by the cover cloth, and there is a gap between the covering cloth and the cover cloth.

[0020] By adopting the above technical solution, the supporting frame provides support for the covering cloth, and the covering cloth is placed around the periphery of the spraying end to reduce the upward dispersion of paint mist and organic waste gas.

[0021] Optionally, the top of the main body of the spray booth is provided with an air inlet skylight, which is used to blow gas onto the cover cloth and the covering cloth.

[0022] By adopting the above technical solution, the air inlet skylight can blow gas from the outside into the paint booth, and the air inlet skylight blows the gas onto the cover cloth and wrapping cloth, reducing the diffusion of paint mist and organic waste gas outward, and causing the gas in the paint booth to flow downward, which is conducive to the collection and treatment of paint mist and organic waste gas by the exhaust gas collection and treatment equipment.

[0023] Optionally, the exhaust gas collection and treatment device includes: A suction box is located at the bottom of the main body of the spray booth; A purification device is connected to the suction box. The purification device is used to create a negative pressure inside the suction box and to purify the gas being drawn in.

[0024] By adopting the above technical solution, the purification device creates a negative pressure inside the suction box, which draws in the gas from the bottom of the paint booth. The gas then enters the purification device and is purified, thus facilitating emissions that meet standards.

[0025] Optionally, the suction box includes: The first suction box is disposed at the bottom end of the support frame; The second suction box is located at the bottom of the paint booth, and the suction surface of the second suction box corresponds to the space enclosed by the cover cloth.

[0026] By adopting the above technical solution, the first suction box can move with the support frame, thereby sucking up the paint mist and organic waste gas at the bottom of the support frame; the second suction box can suck up the space directly below the cover, thereby reducing the outward diffusion of paint mist and organic waste gas.

[0027] In summary, this application includes at least one of the following beneficial effects: 1. The painting unit sprays paint on the workpiece within the space enclosed by the tarpaulin. The tarpaulin reduces the dispersion of paint mist and organic waste gas to the outside of the tarpaulin. After the workpiece is painted, the exhaust gas treatment and collection device draws in the gas from the bottom of the spray booth, causing the paint mist and organic waste gas inside the tarpaulin to be adsorbed into the exhaust gas treatment and collection device. The exhaust gas treatment and collection device then purifies the paint mist and organic waste gas to achieve compliant emissions. 2. The first linear slide can drive the traction block to move up and down, and drive the bottom end of the cover cloth to move up and down, thereby adjusting the space covered by the cover cloth, which is conducive to the workpiece entering and exiting from the cover cloth. 3. The drive source can move the support tube up and down, the sliding table can move the support block in the horizontal direction, and the moving parts can move the paint spray head. Together they can adjust the position of the paint spray head, which is conducive to moving the paint spray head to the appropriate spraying position. Attached Figure Description
