Therefore, there is a need for equipment that can automatically perform powder coating on aluminum square tubes to improve work efficiency and coating results. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing aluminum square tube powder coating equipment, which mostly relies on manual operation, resulting in low work efficiency and uneven powder coating effects. Therefore, this invention proposes an automatic powder coating equipment for aluminum square tube production.

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

[0006] An automatic powder coating equipment for aluminum square tube production includes a base, an inverted U-shaped frame fixed to the top of the base, and multiple powder coating nozzles for powder coating fixed to the inner walls on both sides of the inverted U-shaped frame.

[0007] The base has a sliding platform on its upper side, and two vertical plates are fixed at the top of the platform. Multiple positioning components are provided in the two vertical plates, which are used to fix the aluminum square tube.

[0008] A feeding assembly, located between the base and the moving platform, is used to feed aluminum square tubes into the inverted U-shaped frame for powder coating.

[0009] And a swing assembly used in conjunction with the feeding assembly, the swing assembly being used to drive the aluminum square tube to swing continuously during movement.

[0010] In one possible design, each set of positioning components includes two rotating cylinders, which rotate within two vertical plates respectively. Each of the two rotating cylinders has a third groove, and a square locking block slides within each of the two third grooves. A sliding rod is fixed to the far ends of the two square locking blocks, and the two sliding rods move outward through both ends of the rotating cylinders respectively. A positioning spring is fixed to the far ends of the two square locking blocks, and the two positioning springs are respectively fixed within the two third grooves and respectively sleeved within the two sliding rods.

[0011] In one possible design, pull plates are fixed to the far ends of the two slide rods.

[0012] In one possible design, the feeding assembly includes a first groove formed in the base, a threaded plate sliding in the first groove, a lead screw rotating in the first groove, the threaded plate being threadedly connected to the surface of the lead screw, and a drive motor fixed to the side end of the base, the drive motor being fixedly connected to the lead screw via a coupling.

[0013] In one possible design, the swing assembly includes two fourth grooves, which are respectively opened in two vertical plates. Driven gears are fixed on the surfaces of multiple rotating cylinders. Drive racks slide in both fourth grooves, and the two drive racks mesh with multiple driven gears respectively.

[0014] In one possible design, the swing assembly further includes two fixed plates, which are respectively fixed to both sides of the top of the base. Multiple semi-circular protrusions are fixed to the top of each of the two fixed plates. A second groove is provided inside the moving platform, and four limiting rods are fixed within the second groove. A common lifting plate slides on the surface of the four limiting rods.

By starting the drive motor, the lead screw is rotated, and the rotation of the lead screw drives the threaded plate to move. The movement of the threaded plate drives the moving platform and the fixed aluminum square tube to move. The aluminum square tube moves between multiple powder coating nozzles for powder coating. When the moving platform moves, it drives the adjusting rod to move. The adjusting rod is pressed by the semi-circular protrusion. The semi-circular protrusion drives the lifting plate to rise by pressing the adjusting rod. The lifting plate drives the two connecting rods to rise. The rise of the connecting rods drives the drive rack to move upward. The movement of the drive rack drives multiple driven gears to rotate at an angle, so that the rotating drum rotates. The rotating drum drives the aluminum square tube to flip during powder coating, so that the aluminum square tube can be powder coated evenly.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1: Refer to Figures 1-4 An automatic powder coating equipment for aluminum square tube production is disclosed. This equipment, applied in the field of aluminum square tube production technology, includes a base 1. An inverted U-shaped frame 2 is fixed to the top of the base 1. Multiple powder coating nozzles 4 are fixed to the inner walls of both sides of the inverted U-shaped frame 2 for powder coating. A movable platform 3 slides on the upper side of the base 1. Two vertical plates 5 are fixed to the top of the movable platform 3. Multiple sets of positioning components are provided within the two vertical plates 5 for fixing the aluminum square tubes.

[0027] A feeding assembly is located between the base 1 and the moving platform 3 to feed aluminum square tubes into the inverted U-shaped frame 2 for powder coating. The feeding assembly includes a first groove 7 formed in the base 1, a threaded plate 8 sliding in the first groove 7, and a lead screw 25 rotating in the first groove 7. The threaded plate 8 is threadedly connected to the surface of the lead screw 25. A drive motor 9 is fixed to the side end of the base 1, and the drive motor 9 is fixedly connected to the lead screw 25 through a coupling. When the drive motor 9 is working, it drives the lead screw 25 to rotate through the coupling. When the lead screw 25 rotates, it drives the threaded plate 8 to slide in the first groove 7, thereby pushing the moving platform 3 to move and realizing the feeding function.

[0028] It also includes a swing assembly used in conjunction with the feeding assembly. The swing assembly is used to drive the aluminum square tube to swing continuously during movement. The swing assembly includes two fourth grooves 21, which are respectively opened in two vertical plates 5. Driven gears 23 are fixed on the surface of multiple rotating cylinders 6. Drive racks 24 slide in both fourth grooves 21, and the two drive racks 24 mesh with the multiple driven gears 23 respectively. When the drive racks 24 slide in the fourth grooves 21, they can drive the driven gears 23 to rotate, thereby driving the rotating cylinders 6 and the square locking block 20 to rotate, realizing the swing function of the aluminum square tube.

[0029] The swing assembly also includes two fixed plates 15, which are respectively fixed to the two sides of the top of the base 1. Each fixed plate 15 has multiple semi-circular protrusions 16 fixed to its top. A second groove 12 is formed inside the moving platform 3, and four limiting rods 11 are fixed within the second groove 12. A single lifting plate 13 slides on the surface of the four limiting rods 11. Connecting rods 10 are fixed to the bottom ends of the two drive racks 24, and both connecting rods 10 move downwards through the second groove 12. Both connecting rods 10 are fixed to the top of the lifting plate 13. The lifting plate 13 slides within the second groove 12 and is limited by the limiting rods 11. When the moving platform 3 moves, it drives the lifting plate 13 to slide on the limiting rods 11. The sliding of the lifting plate 13 drives the connecting rods 10 and the drive racks 24 to move, thus achieving the swing function.

[0030] An adjusting rod 14 is fixed inside the lifting plate 13. The two adjusting rods 14 respectively press against the corresponding semi-circular protrusions 16. The semi-circular protrusions 16 can press against the adjusting rods 14, so that the lifting plate 13 is compressed and rises during the movement.

[0031] Each positioning assembly includes two rotating cylinders 6, each with a third groove 17. A square locking block 20 slides within each of the three grooves 17. A sliding rod 18 is fixed to the far ends of each square locking block 20, extending outwards through both ends of the rotating cylinder 6. A positioning spring 26 is fixed to the far ends of each square locking block 20, and is respectively fixed within the three grooves 17 and fitted into the sliding rods 18. An aluminum square tube is placed between the two rotating cylinders 6, and the square locking block 20 is pressed, causing it to slide within the third groove 17 and compress the positioning spring 26. When the square locking block 20 moves to the appropriate position, the positioning spring 26 returns to its original position, causing the square locking block 20 to fix the aluminum square tube in place.

[0032] Pull plates 19 are fixed to the ends of the slide rod 18 that are far apart.

[0033] Example 2: Refer to Figures 1-4 An improvement upon embodiment 1 is made by fixing a return spring 22 to the top of each of the two drive racks 24, with the two return springs 22 respectively fixed within the two fourth grooves 21. The return springs 22 can drive the drive racks 24 to reset, allowing the oscillation function to continue.

[0034] However, as is well known to those skilled in the art, the working principle and wiring method of the drive motor 9 are commonplace and are all conventional methods or common knowledge, so they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
