Description

Technical Field

[0001] This utility model relates to the field of aluminum plate processing technology, specifically to a spraying equipment for aluminum plate processing. Background Technology

[0002] Aluminum sheet processing is a relatively complex process, encompassing multiple stages such as cutting, forming, and surface treatment. Surface treatment in aluminum sheet processing includes anodizing, spraying, and wire drawing. Anodizing involves placing the aluminum sheet as the anode in a specific electrolyte, where an oxide film is formed on the aluminum sheet surface through electrolysis. Spraying uses spraying equipment to evenly spray paint onto the aluminum sheet surface, forming a protective film. Different types of paints can be selected for spraying, such as polyester paint and fluorocarbon paint, to meet different application requirements. Sprayed aluminum sheets have good weather resistance and decorative properties, effectively preventing the aluminum sheet from being corroded and worn by the external environment. Wire drawing, on the other hand, uses methods such as mechanical friction or chemical corrosion to form fine, thread-like textures on the aluminum sheet surface.

[0003] Chinese utility model patent application CN221638518U discloses a double-sided aluminum plate spraying device, which uses conveyor rollers on a conveyor table to transport aluminum plates to the spraying chamber for spraying. However, when workers hoist or place the aluminum plates on the conveyor rollers, they cannot guarantee the accurate placement of the aluminum plates. As the conveyor rollers transport the aluminum plates, they gradually shift, causing the aluminum plates to collide with the conveyor table, resulting in damage to the aluminum plates and affecting the spraying effect. Moreover, after the shifted aluminum plates enter the spraying chamber, the inaccurate position of the aluminum plates leads to uneven spraying. Therefore, a spraying device for aluminum plate processing is proposed to solve the above problems. Utility Model Content

It has the advantage of being able to easily adjust the offset aluminum plate, solving the problems that when workers hoist or place aluminum plates on the conveyor rollers, they cannot ensure the accurate placement of the aluminum plates. As the aluminum plates are transported by the conveyor rollers, they gradually shift, causing the aluminum plates to collide with the conveyor table, resulting in damage to the aluminum plates and affecting the spraying effect. Moreover, after the offset aluminum plates enter the spraying box, the inaccurate position of the aluminum plates leads to uneven spraying.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a spraying equipment for aluminum plate processing, comprising a conveyor table, a transmission roller, a spraying chamber and a powder supply unit, wherein the conveyor table is provided with a correction structure;

The drive unit is installed on the top of the rectangular frame.

[0007] Furthermore, the drive unit includes a transmission gear, two L-shaped racks, and a feed component. The transmission gear is rotatably mounted on the top of the rectangular frame. The two L-shaped racks are respectively fixedly connected to two connecting plates, and both L-shaped racks mesh with the transmission gear. The feed component is fixedly mounted on the top of the rectangular frame and is used to control the movement of the left L-shaped rack.

[0008] Furthermore, the drive roller is rotatably mounted on the conveyor platform, the spraying chamber is fixedly mounted on the conveyor platform, a powder supply unit is installed on the spraying chamber, and an aluminum plate is provided on the drive roller.

[0009] Furthermore, two guide rods are fixedly installed between the front and rear side walls of the inner cavity of the rectangular frame. Two through holes are opened inside the two correction plates. One end of the guide rod passes through the through hole. The inner wall of the through hole is slidably connected to the outer surface of the guide rod. Five semi-circular grooves are opened at the bottom of the two correction plates.

[0010] Furthermore, each of the two auxiliary roller groups includes six guide rollers, and a rubber sleeve is fixedly installed on the outer surface of the guide rollers. The six guide rollers on the same side are rotatably installed inside the mounting frame, and the guide rollers extend through the space between two adjacent drive rollers.

[0011] Furthermore, a support frame is fixedly installed on the top of the rectangular frame, and an installation rod is rotatably installed between the inner top wall of the support frame and the top of the rectangular frame, with the transmission gear fixedly installed on the outer surface of the installation rod.

The auxiliary roller group consists of multiple rotating guide rollers with rubber sleeves on their outer surfaces, which can adapt to aluminum plates of different sizes and shapes. The correction is performed by contacting the aluminum plate surface without damaging the surface or affecting the efficiency of the transmission rollers in conveying the aluminum plate. Furthermore, the correction plate can slide within a rectangular frame, allowing the correction range to be adjusted according to aluminum plates of different widths, improving the equipment's versatility and adaptability.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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 protection scope of the present utility model.

[0025] Example 1: Please refer to Figure 1-7 In this embodiment, a spraying device for aluminum plate processing includes a conveyor table 1, a transmission roller 2, a spraying chamber 3, and a powder supply unit 4. The conveyor table 1 is provided with a correction structure, the transmission roller 2 is rotatably mounted on the conveyor table 1, the spraying chamber 3 is fixedly mounted on the conveyor table 1, the powder supply unit 4 is installed on the spraying chamber 3, and an aluminum plate 6 is provided on the transmission roller 2.

[0026] Example 2: Please refer to Figure 1-7 Based on Embodiment 1, the correction structure includes a rectangular frame 51, two correction plates 52, two mounting frames 53, two auxiliary roller groups 54, two rectangular grooves 55, two connecting plates 56, and a drive unit. The rectangular frame 51 is fixedly installed on the top of the conveyor table 1. The two correction plates 52 are slidably installed inside the rectangular frame 51. The two mounting frames 53 are fixedly installed on opposite sides of the two correction plates 52. The two auxiliary roller groups 54 are installed on the two mounting frames 53. The two rectangular grooves 55 are both opened on the rectangular frame 51. The two connecting plates 56 are fixedly connected to the two correction plates 52. The two connecting plates 56 pass through the two rectangular grooves 55 and are slidably connected to the inner wall of the rectangular grooves 55. The drive unit is installed on the top of the rectangular frame 51.

[0027] Two guide rods are fixedly installed between the front and rear side walls of the inner cavity of the rectangular frame 51. Two through holes are opened inside the two correction plates 52. One end of the guide rod passes through the through hole, and the inner wall of the through hole is slidably connected to the outer surface of the guide rod. Five semi-circular grooves are opened at the bottom of the two correction plates 52. The guide rods guide the sliding trajectory of the correction plates 52, thereby stabilizing the sliding process of the correction plates 52, and the semi-circular grooves at the bottom of the correction plates 52 are sleeved on the corresponding transmission rollers 2.

[0028] In addition, each of the two auxiliary roller groups 54 includes six guide rollers. Rubber sleeves are fixedly installed on the outer surface of the guide rollers. The six guide rollers on the same side are rotatably installed inside the mounting frame 53. The guide rollers pass through the space between two adjacent drive rollers 2. By inserting multiple guide rollers between two adjacent drive rollers 2, the position of the aluminum plate 6 is restricted and corrected by the guide rollers, and the efficiency of the drive rollers 2 in conveying the aluminum plate 6 is ensured.

[0029] Using the above technical solution, the drive unit controls the two connecting plates 56 to move to the opposite side, so the correction plate 52 will slide along the direction of the guide rod within the rectangular frame 51, thereby controlling the two correction plates 52 to move to the opposite side. The moving correction plate 52 drives the auxiliary roller group 54 to move synchronously through the mounting frame 53. At this time, the position of the aluminum plate 6 is corrected by the two auxiliary roller groups 54, and the aluminum plate 6 continues to be conveyed towards the spraying chamber 3 under the action of the guide roller, ensuring the conveying speed of the aluminum plate 6. Moreover, the surface of the aluminum plate 6 is protected by the rubber sleeve to avoid damage to the surface of the aluminum plate 6 during the correction process.

[0030] Example 3: Please refer to Figure 1-7 Based on Embodiment 2, the drive unit includes a transmission gear 57, two L-shaped racks 58, and a feed component 59. The transmission gear 57 is rotatably mounted on the top of the rectangular frame 51. The two L-shaped racks 58 are fixedly connected to two connecting plates 56 respectively. Both L-shaped racks 58 mesh with the transmission gear 57. The feed component 59 is fixedly mounted on the top of the rectangular frame 51 and is used to control the movement of the left L-shaped rack 58.

[0031] A support frame is fixedly installed on the top of the rectangular frame 51. An installation rod is rotatably installed between the inner top wall of the support frame and the top of the rectangular frame 51. The transmission gear 57 is fixedly installed on the outer surface of the installation rod. The installation rod and the support frame stabilize the rotation of the transmission gear 57, so that the rotating transmission gear 57 can drive the L-shaped rack 58 to move.

[0032] In addition, two limiting strips are fixedly installed on the top of the rectangular frame 51. The opposite sides of the two limiting strips are slidably connected to the opposite sides of the two L-shaped racks 58. By limiting the two L-shaped racks 58 with the two limiting strips, the two L-shaped racks 58 can only move along the direction of the limiting strips, thereby stabilizing the movement process of the two L-shaped racks 58.

[0033] It should be noted that the feed component 59 includes an electric push rod and a connector. The electric push rod is fixedly installed on the top of the rectangular frame 51. The telescopic end of the electric push rod is fixedly connected to the connector. The connector is fixedly connected to the left L-shaped rack 58. When the electric push rod is activated, it telescopically extends and retracts, causing the connector to move synchronously. In turn, the moving connector drives the left L-shaped rack 58 to move.

[0034] Using the above technical solution, the aluminum plate 6 is conveyed by the transmission roller 2 towards the spraying chamber 3. The electric push rod in the feeding component 59 is activated. The telescopic end of the electric push rod drives the left L-shaped rack 58 to move through the connecting piece, so that the moving L-shaped rack 58 drives the transmission gear 57 to rotate, thereby driving the right L-shaped rack 58 to move in the opposite direction.

[0035] The working principle of the above embodiments is as follows:

[0036] In use, the aluminum plate 6 is conveyed by the transmission roller 2 towards the spraying chamber 3. The electric push rod in the feed component 59 is activated. The telescopic end of the electric push rod drives the left L-shaped rack 58 to move through the connector, so that the moving L-shaped rack 58 drives the transmission gear 57 to rotate, thereby driving the right L-shaped rack 58 to move in the opposite direction.

[0037] L-shaped rack 58 is fixedly connected to connecting plate 56, and connecting plate 56 is fixed to correction plate 52. Therefore, correction plate 52 will slide along the direction of guide rod within rectangular frame 51, thereby controlling the two correction plates 52 to move to the opposite side. The moving correction plate 52 drives the auxiliary roller group 54 to move synchronously through mounting frame 53. At this time, the position of aluminum plate 6 is corrected by the two auxiliary roller groups 54, and aluminum plate 6 continues to be conveyed towards spray chamber 3 under the action of guide roller, ensuring the conveying speed of aluminum plate 6. Moreover, rubber sleeve is used to protect the surface of aluminum plate 6 to avoid damage to the surface of aluminum plate 6 during the correction process.

[0038] The corrected aluminum plate 6 is conveyed to the spraying chamber 3 for spraying, while the powder supply unit 4 continuously provides paint for the aluminum plate 6 until the aluminum plate 6 is sprayed and then conveyed to the subsequent processing line by the drive roller 2.
