Description

Technical Field

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

[0002] Metal pipe fittings are pipes in various shapes, such as square and round, made of metal materials, and are widely used in construction, machinery, chemical and other fields. To improve the aesthetics, corrosion resistance and other properties of metal pipe fittings, they are usually coated during the production process. Therefore, metal pipe fitting coating machines have become key equipment in pipe fitting processing.

[0003] In the prior art, a spraying device for processing hollow aluminum alloy tubes, with publication number CN219111981U and publication date June 2, 2023, includes a fixed base. A first drive motor is installed on the left side inside the fixed base, and a drive screw is installed at the output end of the first drive motor. A first fixed column is slidably installed on the left side of the upper end of the fixed base via a slider, and the slider is threadedly connected to the drive screw. A second fixed column is fixedly installed on the right side of the upper end of the fixed base. A fixed plate is rotatably installed on one side of the upper ends of both the first and second fixed columns via a rotating shaft. Adjusting screws are installed on the upper and lower sides of the fixed plates, and sliding plates are installed outside the adjusting screws. An electric push rod, slidably connected to the fixed plate, is installed on the side of the sliding plate near the middle position of the fixed plate. This device fixes the alloy tube by expanding the support from the inner wall of the alloy tube outwards, facilitating the spraying operation. In current spraying operations, water-based paints are increasingly used to reduce environmental pollution. However, the existing equipment lacks effective measures to recover the sprayed paint, which causes most of the paint to accumulate inside the equipment. Long-term use not only results in a serious waste of paint raw materials, but also increases the difficulty and cost of equipment cleaning and maintenance, failing to meet the processing requirements of energy conservation and environmental protection. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the present invention aims to provide a spraying equipment for aluminum alloy tube processing, which solves the problem of raw material waste caused by the lack of paint recycling mechanism in the existing spraying equipment, and at the same time achieves stable fixation and uniform spraying of aluminum alloy tubes of different specifications.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a spraying equipment for aluminum alloy tube processing, including a workbench, a spraying chamber fixedly connected to the surface of the workbench, a recovery chamber fixedly connected to the bottom of the workbench, storage chambers on both sides of the spraying chamber, a spraying pipe connected to the bottom of the storage chamber passing through the spraying chamber and fixedly connected to the nozzle, a vertical track is provided inside the spraying chamber, and the bottom end of a linear mechanism set on the surface of the vertical track is fixedly connected to the nozzle; a rotatable circular rotating seat is provided at the bottom of the inner cavity of the spraying chamber, a condensation cylinder is provided at the center of the surface of the rotating seat, multiple positioning plates are fixedly connected at equal intervals on the upper surface edge of the rotating seat, positioning columns are fixedly connected to the surface of the positioning plates, and the positioning columns extend into the lower end of the aluminum alloy tube; a top cover is provided at the top of the spraying chamber, a lifting mechanism is hinged to the bottom of the top cover, multiple secondary motors of the same number as the positioning plates are fixedly connected to the bottom of the lifting mechanism, a double-axis telescopic rod is fixedly connected to the output shaft of each secondary motor, and support claws are fixedly connected to both ends of the double-axis telescopic rods, the bottom ends of the support claws can abut against the inner wall of the aluminum alloy tube.

[0006] The rotation of the rotating seat is achieved by a gear ring installed at the bottom of the rotating seat, a primary motor installed inside the worktable, and a gear fixedly connected to one end of the primary motor. The gear meshes with the gear ring, and the primary motor drives the rotating seat to rotate.

[0007] The upper surface of the rotating seat has an inclined structure with the outer side higher than the inner side. Multiple discharge ports are opened around the condenser cylinder on the rotating seat. A discharge pipe is opened on the surface of the worktable. The discharge ports are connected to the discharge pipe, and the bottom end of the discharge pipe is fixedly connected to the recovery chamber.

[0008] Compression springs are fixedly connected to both sides of the positioning column, and a support plate is fixedly connected to the other end of the compression springs. Multiple rollers are provided on the outside of the support plate, and the rollers can abut against the inner wall of the aluminum alloy tube.

[0009] A cooling chamber is provided outside the spraying chamber. A circulating pump is installed inside the cooling chamber. Cooling water is stored on top of the circulating pump in the cooling chamber. A cold liquid pipe is provided at one end of the circulating pump. The cold liquid pipe passes into the condenser cylinder in a spiral direction. The other end of the cold liquid pipe is connected to the cooling water.

[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. Strong adaptability: Through the synergistic action of the support plate and support claws, the outward expansion support is achieved simultaneously from the bottom and top of the aluminum alloy tube. Combined with the elastic adjustment of the compression spring and the telescopic adjustment of the dual-axis telescopic rod, it can be adapted to aluminum alloy tubes of different diameters and lengths, greatly improving the versatility of the equipment. 2. High uniformity of spraying: The primary motor drives the rotating seat to rotate the aluminum alloy tube, and the secondary motor drives the aluminum alloy tube to rotate on its own axis. Together with the spray head, the nozzle moves up and down along the vertical track under the drive of the linear mechanism, so that all parts of the aluminum alloy tube surface can be evenly contacted with the paint, effectively avoiding the problems of spraying dead corners and uneven thickness. 3. High efficiency in paint recycling: The inclined rotating seat with a higher outer edge and a lower inner edge allows excess paint to automatically collect at the discharge port under gravity during the spraying process; at the same time, the condensate film formed on the surface of the condenser cylinder fully dissolves water-based paint and collects it with the water flow to the recycling chamber, significantly reducing paint waste, reducing environmental pollutant emissions, and lowering processing costs.

[0013] The following description, in conjunction with the accompanying drawings, details a spraying device for processing aluminum alloy tubes according to this utility model.

[0014] This utility model relates to a spraying equipment for processing aluminum alloy tubes. See [link to relevant documentation]. Figures 1 to 5 The system includes a workbench 1, a spray chamber 2 fixedly connected to the surface of the workbench 1, and a recovery chamber 25 fixedly connected to the bottom of the workbench 1. Both sides of the spray chamber 2 have material storage chambers 19, with a spray pipe 18 connected to the bottom of each material storage chamber 19. The spray pipe 18 passes through the spray chamber 2 and is fixedly connected to a spray head 17. A vertical track is installed inside the spray chamber 2, and a linear mechanism 16 is installed on the surface of the vertical track. The bottom of the linear mechanism 16 is fixedly connected to the spray head 17.

[0015] A circular rotating seat 4 is located at the bottom of the inner cavity of the spraying chamber 2. A condenser cylinder 20 is located at the center of the surface of the rotating seat 4. Multiple positioning plates 6 are fixedly connected at equal intervals along the edge of the surface of the rotating seat 4. Positioning posts 7 are fixedly connected to the surface of the positioning plates 6. An aluminum alloy tube 11 is located on the outside of the positioning posts 7. A gear ring is located at the bottom of the rotating seat 4. A primary motor 5 is located inside the worktable 1. One end of the primary motor 5 is fixedly connected to a gear, and one side of the gear meshes with the gear ring. When the primary motor 5 is started, it drives the gear to rotate, which in turn drives the rotating seat 4 to rotate through the meshing of the gear and gear ring, causing the aluminum alloy tube 11 and the telescopic rod 13 to revolve synchronously.

[0016] A top cover 3 is installed at the top of the spraying chamber 2. A lifting mechanism 15 is hinged to the bottom of the top cover 3. Multiple secondary motors 14 are fixedly connected to the bottom of the lifting mechanism 15. Each secondary motor 14 corresponds vertically to a positioning plate 6. The output shaft of each secondary motor 14 is fixedly connected to a double-axis telescopic rod 13. Support claws 12 are fixedly connected to both ends of the telescopic rod 13. The bottom of the support claws 12 abuts against the inner wall of the aluminum alloy tube 11. The height of the support claws 12 can be changed by adjusting the lifting mechanism 15 according to the length of the aluminum alloy tube 11, so that the support claws 12 extend into the tube of the aluminum alloy tube 11. Then, the telescopic rod 13 extends and retracts to make the support claws 12 press firmly against the inner wall of the aluminum alloy tube 11. This device can fix aluminum alloy tubes 11 of different lengths. Starting the secondary motors 14 can drive the aluminum alloy tube 11 fixed by the support claws 12 to rotate.

[0017] Compression springs 8 are fixedly connected to both sides of the positioning post 7, and a support plate 9 is fixedly connected to the other end of the compression springs 8. Multiple rollers 10 are provided on the outer side of the support plate 9, and the other end of the rollers 10 abuts against the inner wall of the aluminum alloy tube 11. When the aluminum alloy tube 11 is fitted onto the outer side of the positioning post 7, the compression springs 8 push the support plate 9 to make the rollers 10 press against the inner wall of the aluminum alloy tube 11, thus achieving bottom support. When the aluminum alloy tube 11 rotates, the rollers 10 rotate accordingly, ensuring smooth rotation of the aluminum alloy tube 11 and reducing frictional resistance.

[0018] The rotating seat 4 has an outer higher inner wall. Multiple discharge ports are opened around the condenser cylinder 20. A discharge pipe 24 is opened on the surface of the worktable 1. The discharge ports are connected to the discharge pipe 24. The bottom end of the discharge pipe 24 is fixedly connected to the recovery chamber 25. During the spraying process, a relatively large amount of paint is collected into a ball and flows along the inclined surface of the rotating seat 4 under the action of gravity through the discharge port and then through the discharge pipe 24 into the recovery chamber 25.

[0019] A cooling chamber 23 is located at one end of the spraying chamber 2. A circulating pump 22 is installed inside the cooling chamber 23, and a certain amount of cooling water is stored at the top of the circulating pump 22. A coolant pipe 21 is installed at one end of the circulating pump 22, which spirally enters the condenser cylinder 20. The other end of the coolant pipe 21 is connected to the cooling water. After spraying, a certain amount of paint adheres to the surface of the condenser cylinder 20. Cooling water is drawn from the cooling chamber 23 by the circulating pump 22. The circulating pump 22 is started, and the cooling water circulates within the coolant pipe 21. Under the action of the low-temperature cooling water, the surface temperature of the condenser cylinder 20 decreases, forming a condensate film. During the spraying process, the paint adhering to the surface of the condenser cylinder 20 dissolves in the water film and flows into the recovery chamber 25 with the water flow.

[0020] The working process of this utility model is as follows: First, open the top cover 3, and place the aluminum alloy tubes 11 to be sprayed one by one on the outside of the positioning post 7. Utilize the elastic tension of the compression spring 8 to make the rollers 10 on the support plate 9 press against the inner wall of the aluminum alloy tube 11 to achieve initial bottom fixation. Then, close the top cover 3, adjust the lifting mechanism 15 according to the length of the aluminum alloy tube 11, so that the support claws 12 extend into the interior of the aluminum alloy tube 11, and control the extension and retraction of the double-axis telescopic rod 13 so that the support claws 12 press against the inner wall of the aluminum alloy tube 11 from the top to complete the stable fixation of the aluminum alloy tube 11.

[0021] Start the primary motor 5 and the secondary motor 14. The primary motor 5 drives the rotating seat 4 to revolve through gear and gear ring transmission, and the secondary motor 14 drives the aluminum alloy tube 11 to rotate. At the same time, the paint in the storage chamber 19 is transported to the spray nozzle 17 through the spray pipe 18. The spray nozzle 17 moves up and down along the vertical track under the drive of the linear mechanism 16 to spray the surface of the aluminum alloy tube 11 evenly in all directions.

[0022] During the spraying process, some of the excess paint collects along the inclined surface of the rotating seat 4 to the discharge port and flows into the recovery chamber 25 through the discharge pipe 24. The other part adheres to the surface of the condenser cylinder 20. When the circulation pump 22 is started, cooling water circulates in the condenser cylinder 20 through the spiral coolant pipe 21, forming a condensate film on the surface of the condenser cylinder 20. The adhered paint dissolves in the water film and flows into the recovery chamber 25 with the water flow, achieving efficient paint recovery.

[0023] After the spraying is completed, turn off all power mechanisms and the spraying system, adjust the lifting mechanism 15 and the telescopic rod 13, loosen the support claw 12, and open the top cover 3 to take out the sprayed aluminum alloy tube 11.
