Description

Technical Field

[0001] This utility model relates to the field of spraying equipment technology, and in particular to a spraying equipment for spraying powder onto aluminum profiles. Background Technology

[0002] In industrial production, aluminum profiles are widely used in many fields such as construction, automobiles, and electronics due to their advantages of light weight, high strength, and aesthetics. However, aluminum profiles are susceptible to corrosion in natural environments, and surface treatment is crucial to meet different decorative and functional requirements. With the development of powder coating technology, it has shown great advantages in the surface treatment of aluminum profiles, providing excellent corrosion resistance, decorative properties, and environmental performance.

[0003] However, existing aluminum profile powder coating equipment still has some shortcomings. For some small coating equipment, when using it, it is necessary to manually hold the spray gun and spray it onto the workpiece. At the same time, the spray gun must be rotated at any time to ensure that there are no dead corners on the workpiece. It is also necessary to rotate the workpiece to ensure that all four sides of the workpiece are coated. Therefore, an aluminum profile powder coating equipment was designed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a powder coating device for aluminum profiles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A powder coating device for aluminum profiles includes a housing with a side door on one side. A first motor is fixedly connected to the top side of the housing near the center. A rotating mechanism and a driving mechanism are located in the middle of the inner side of the housing. The driving mechanism includes a strip block fixedly connected to the inner side of the top of the housing. A T-shaped groove is formed on the strip block, and a T-shaped block is slidably connected in the T-shaped groove. Round rods are slidably fitted on both sides of the T-shaped block. Round holes that match the round rods are formed at both ends of the T-shaped block. A ratchet rack is fixedly connected to the side of the two round rods near the center of the housing. A protrusion is fixedly connected to the other end of the two round rods. A fourth spring is fitted to the end of the two round rods near the ratchet rack. A first vertical plate is fixedly connected to the bottom of the T-shaped block away from the first motor. A miniature electric push rod is fixedly connected to the bottom of the first vertical plate near the first motor, and a triangular block is fixedly connected to the other end of the miniature electric push rod. By extending and retracting the miniature electric push rod, the distance between the triangular block and the roller is controlled, thereby controlling the rotation angle of the turntable of the rotating mechanism.

[0007] As a further embodiment of this utility model, the driving mechanism further includes a second vertical plate fixedly connected to the bottom of the strip block on the side away from the first motor. A limiting rod is slidably sleeved at the bottom of the second vertical plate, and a round hole adapted to the limiting rod is opened at the bottom of the second vertical plate. One end of the limiting rod is fixedly connected to one side of the first vertical plate, and the other end of the limiting rod is fixedly connected to a limiting block. A third spring is sleeved at the end of the limiting rod near the first vertical plate. The setting of the third spring facilitates the reset of the triangular block, T-shaped block, etc.

[0008] As a further embodiment of this utility model, the rotating mechanism includes a rotating rod rotatably connected to the middle position of the bottom of the inner side of the housing. A turntable is fixedly connected to the bottom of the rotating rod. Fixed blocks are fixedly connected to both ends of the bottom of the turntable. A bidirectional lead screw is rotatably connected between the two fixed blocks. Clamping plates are screwed to both ends of the bidirectional lead screw. A lead screw nut adapted to the bidirectional lead screw is fixedly sleeved on both clamping plates. A second motor is fixedly connected to one of the fixed blocks, and the output end of the second motor passes through the end of the fixed block where the bidirectional lead screw is fixedly connected.

[0009] As a further embodiment of this utility model, the rotating mechanism further includes a ratchet fixedly sleeved in the middle of the rotating rod, and the ratchet is adapted to the ratchet rack. A U-shaped block is fixedly connected to the inner side of the top of the housing near the ratchet. The same sliding rod is fixedly connected between the two ends of the inner side of the U-shaped block. A sliding block is slidably sleeved on the circumferential surface of the sliding rod, and a circular hole adapted to the sliding rod is opened on the top of the sliding block. The top of the sliding block is in contact with the U-shaped block. A slanted locking block is fixedly connected to one side of the bottom of the sliding block, and the slanted locking block is adapted to the ratchet. A first spring is sleeved on the end of the sliding rod away from the ratchet. The slanted locking block, the sliding rod, etc., ensure that the ratchet will not reverse.

[0010] As a further embodiment of this utility model, a lead screw is fixedly connected to the bottom output end of the first motor through the housing. The bottom of the lead screw is rotatably connected to the inner side of the bottom of the housing. A lifting block is screwed onto the circumferential surface of the lead screw. A screw nut adapted to the lead screw is fixedly sleeved on the lifting block. A guide rod is slidably sleeved on the other end of the lifting block, and the guide rod is fixedly connected between the top and bottom of the housing. A circular hole adapted to the guide rod is opened on the lifting block.

[0011] As a further embodiment of this utility model, a spray gun is fixedly connected to the bottom of the lifting block, and a roller is rotatably connected to the side of the lifting block near the triangular block, and the roller is adapted to the triangular block.

[0012] As a further embodiment of this utility model, a negative pressure adsorption cylinder is fixedly connected to the bottom of the inner side of the housing away from the spray gun, and a vacuum pump is fixedly connected to the bottom of the negative pressure adsorption cylinder.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model utilizes a roller, a rotating mechanism, and a driving mechanism. After the spray gun sprays one side of the workpiece, the workpiece automatically and continuously rotates at a certain angle without the need for manual movement of the spray gun. This ensures that even the dead corners of the workpiece are sprayed, effectively solving the problem of cumbersome manual operation mentioned in the background technology. This achieves automatic and uniform spraying of the workpiece, while the automatic rotation of the workpiece at a certain angle facilitates uniform spraying from all sides, reducing manual labor intensity and improving work efficiency.

[0015] This invention allows users to control the rotation angle of the rotating mechanism by setting a miniature electric push rod in the drive mechanism, making it easier to spray areas of the workpiece that are difficult to spray, thus ensuring the quality of the spraying.

A first spring 510 is sleeved on the end of the slide rod 509 away from the ratchet 502. Through the action of the slanted locking block 512, the U-shaped block 508 and the slide rod 509, the ratchet 502 will not reverse when the ratchet rack 612 is reset under the action of the third spring 609.

[0030] In this embodiment, a lead screw 301 is fixedly connected to the bottom output end of the first motor 3 through the housing 1. The bottom of the lead screw 301 is rotatably connected to the inner side of the bottom of the housing 1. A lifting block 4 is screwed onto the circumferential surface of the lead screw 301. A screw nut that matches the lead screw 301 is fixedly sleeved on the lifting block 4. A guide rod 302 is slidably sleeved on the other end of the lifting block 4. The guide rod 302 is fixedly connected between the top and bottom of the housing 1. A round hole that matches the guide rod 302 is opened on the lifting block 4.

[0031] In this embodiment, a spray gun 401 is fixedly connected to the bottom of the lifting block 4, and a roller 402 is rotatably connected to the side of the lifting block 4 near the triangular block 606. The roller 402 is adapted to the triangular block 606. The spray gun 401 pushes the triangular block 606, so that the drive mechanism 6 drives the rotating mechanism 5 to rotate at a certain angle.

[0032] In this embodiment, a negative pressure adsorption cylinder 2 is fixedly connected to the bottom of the inner side of the housing 1 away from the spray gun 401, and a vacuum pump is fixedly connected to the bottom of the negative pressure adsorption cylinder 2. The negative pressure adsorption cylinder 2 is a prior art technology. Through the effect of negative pressure, excess powder will not float arbitrarily.

[0033] Working Principle: In use, first connect the spray gun 401 to the high-pressure air pump and powder box. Move the workpiece to the top of the rotating mechanism 5 through the side door 101. Control the rotation of the second motor 506 to fix the workpiece in place using two clamping plates 507. Rubber anti-slip pads are provided on the adjacent sides of the two clamping plates 507. Turn on the suction pump at the bottom of the negative pressure adsorption cylinder 2 to create negative pressure inside the cylinder, facilitating powder absorption. Start the first motor 3, causing the lead screw 301 to rotate, which in turn causes the lifting block 4 to gradually descend, carrying the spray gun 401, thus spraying one side of the workpiece. When the workpiece reaches the bottom, the first motor 3 reverses, causing the lifting block 4 to rise, carrying the spray gun 401, to continue spraying. When the lifting block 4 reaches the top, the roller 402 will press against the triangular block 606, causing the triangular block 606 to lift the first motor 401 to the top, thus facilitating powder absorption. The vertical plate 604, T-block 603, and ratchet 612 move backward. At this time, the third spring 609 is compressed, and the ratchet 612 rotates the ratchet 502, causing the turntable 503 to rotate the workpiece at a certain angle. Then, the first motor 3 reverses, causing the spray gun 401 to continue to descend. The T-block 603 and other components are reset under the action of the third spring 609, realizing the spraying of the new side. This process is repeated so that all four sides of the workpiece are sprayed without the need for manual movement of the workpiece or the spray gun 401. When it is necessary to adjust the rotation angle of the workpiece each time, the extension length of the triangular block 606 is controlled by controlling the micro electric push rod 605, thereby controlling the distance that the roller 402 pushes the triangular block 606 each time, and thus controlling the rotation angle of the rotating mechanism 5. This allows users to adjust the spraying speed in real time according to different workpieces, improving practicality.
