[0002] A powder coating heating device is a specialized piece of equipment used in the powder coating process to heat a workpiece that has been coated with powder, so that the powder coating can be cured into a film on the surface of the workpiece.

[0003] The device uses hot air circulation heating and infrared radiation heating to transfer heat to the workpiece and the powder coating on its surface. Under the action of heat, the loose powder gradually melts, flows and solidifies, eventually forming a uniform, continuous coating with certain mechanical and protective properties on the workpiece surface.

[0004] In existing heating devices, the workpiece is fixed inside the device. Because the workpiece is inside the device, it will block the flow of hot air, which will not heat the workpiece evenly, resulting in uneven heating rate. To address this, we propose a powder coating heating device. Utility Model Content

[0023] 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.

[0024] Example 1: Please refer to Figure 1-5 This utility model provides a technical solution: a powder coating heating device, including a body 1, a heater 11 is provided in the lower part of the body 1, a safety door 12 is rotatably connected to the front of the body 1, a fixing plate 13 is provided in the upper part of the body 1, a plurality of evenly distributed connecting blocks 21 are slidably connected in the fixing plate 13, a moving part 2 for installing the heated workpiece is provided in the fixing plate 13, and a driving part 4 for moving the connecting blocks 21 is provided in the fixing plate 13.

[0025] The body 1 can provide a sealed space for workpiece processing, the heater 11 indirectly heats the workpiece by heating air, the fixing plate 13 is used to protect the internal structure from external interference, and the connecting block 21 can provide support for the movement of the internal structure.

[0026] Furthermore, the moving part 2 includes a bevel gear 22 rotatably connected inside the connecting block 21. A connecting rod 23 is provided at the lower part of the bevel gear 22. The connecting rod 23 is rotatably connected inside the connecting block 21. A fixing buckle 24 is provided at the lower end of the connecting rod 23. A locking member 5 for locking the fixing buckle 24 is provided inside the fixing buckle 24. A driving member 3 for driving the bevel gear 22 to rotate is provided inside the fixing plate 13.

[0027] The bevel gear 22 is used to drive the connecting rod 23 to rotate, and the connecting rod 23 can drive the fixed buckle 24 to rotate. The rotation of the bevel gear 22 can drive the connecting rod 23 and the fixed buckle 24 to rotate, thereby allowing the workpiece to rotate and be heated at the same time, which improves the efficiency of workpiece processing.

[0028] Furthermore, the drive component 3 includes a toothed plate 31 disposed inside the fixed plate 13, and a bevel gear 33 is rotatably connected inside the connecting block 21. The bevel gear 33 and the bevel gear 22 mesh with each other. A drive wheel 32 is disposed at the end of the bevel gear 33 away from the bevel gear 22, and the drive wheel 32 and the toothed plate 31 mesh with each other.

[0029] The toothed plate 31 is used to provide rotational structural support for the drive wheel 32. The drive wheel 32 can drive the second bevel gear 33 to rotate. The second bevel gear 33 is used to transmit the rotational power of the drive wheel 32 to the first bevel gear 22. Through the cooperation between the toothed plate 31 and the drive wheel 32, the second bevel gear 33 can drive the first bevel gear 22 to rotate.

[0030] Furthermore, the second driving component 4 includes a synchronous wheel 41 rotatably connected to the front and rear sides inside the fixed plate 13. A synchronous belt 42 is sleeved on the outer periphery of the two synchronous wheels 41. A motor 43 is provided on the upper rear side of the machine body 1. The middle part of the rear synchronous wheel 41 is provided at the driving end of the motor 43. The connecting block 21 is provided on the outer periphery of the synchronous belt 42.

[0031] Two synchronous pulleys 41 are used to cooperate with the synchronous belt 42 to make multiple connecting blocks 21 on the outer periphery of the synchronous belt 42 rotate simultaneously, and the motor 43 is used to drive the synchronous pulleys 41 to rotate.

[0032] Furthermore, the locking element 5 includes a locking block 51 that is slidably connected inside the fixing buckle 24. The upper end of the locking block 51 is rotatably connected to a connecting rod 52, and the end of the connecting rod 52 away from the locking block 51 is rotatably connected to a push rod 53. The fixing buckle 24 is provided with a driving element 6 for pushing the push rod 53 back to its original position.

[0033] The locking block 51 is used to block the notch of the fixing buckle 24. The second connecting rod 52 can drive the locking block 51 to move up and down. The push rod 53 is used to pull the second connecting rod 52 to move. By pulling the push rod 53, the second connecting rod 52 can pull the locking block 51 to move upward, thereby opening the installation position of the fixing buckle 24. Then the workpiece can be placed inside the fixing buckle 24.

[0034] Furthermore, the driving component 6 includes a limiting plate 61 located in the middle of the push rod 53. A spring 62 is provided on the side of the limiting plate 61 near the connecting rod 52. The spring 62 is sleeved on the outer periphery of the middle part of the push rod 53. A limiting groove 64 is formed inside the upper part of the fixing buckle 24. The end of the spring 62 away from the limiting plate 61 is located inside the limiting groove 64. The limiting plate 61 slides inside the limiting groove 64. A pull ring 63 is rotatably connected to the end of the push rod 53 away from the connecting rod 52.

[0035] The limiting plate 61 is used to push the compression spring 62 to retract. The spring 62 can rebound to push the limiting plate 61 to move back to its original position. The pull ring 63 is used to pull the push rod 53. The limiting groove 64 provides space for the internal structure to move. After the spring 62 rebounds, it can push the limiting plate 61 and the push rod 53 to move forward and return to their original positions.

[0036] Pulling the pull ring 63 backward causes the push rod 53 and the limiting plate 61 to move backward. The limiting plate 61 compresses the spring 62, causing the push rod 53 to pull the upper end of the connecting rod 52 to move to the right, which in turn rotates and pulls the locking block 51 upward. Holding the workpiece, place it in the mounting opening of the fixing buckle 24. Then, release the pull ring 63 to allow the spring 62 to rebound and push the limiting plate 61 and the push rod 53 to move to the left. The push rod 53 pushes the connecting rod 52 and the locking block 51 back to their original positions. The locking block 51 will close the notch of the fixing buckle 24. Then, start the motor 43 to drive the synchronous pulley 41 to rotate. The synchronous belt 42 can make the two synchronous pulleys 41 rotate in the same direction and at the same speed. This allows the synchronous belt 42 to drive the connecting block 21 to move in a ring inside the fixing plate 13. Then, all the internal parts of the fixing buckles 24 can be rotated. Install all workpieces, then close the safety door 12 and start the heater 11 to heat the workpieces. When the connecting block 21 moves, the toothed plate 31 will push the drive wheel 32 to rotate. The drive wheel 32 will push the bevel gear 23 to drive the bevel gear 1 to rotate. The bevel gear 1 can drive the connecting rod 23 and the fixing buckle 24 to rotate. The workpiece can rotate on its own axis and make a circular revolution around the fixing plate 13 inside the machine body 1. With the heating of the heater 11, each workpiece can be heated evenly. When the workpiece is completely processed, the motor 43 and the heater 11 can be turned off. At this time, the workpiece stops moving inside the machine body 1 and begins to cool down. When the workpiece temperature drops, start the motor 43 to drive the fixing buckle 24 to move, open the safety door 12 and take out the workpiece to complete the processing of the workpiece.

[0037] Example 2: Please refer to Figure 6 Based on Embodiment 1, this utility model provides another technical solution: a load-bearing wheel 34 is provided at the lower part of the connecting block 21, and a groove 35 is provided at the lower part of the fixing plate 13, and the load-bearing wheel 34 slides inside the groove 35.

[0038] The load-bearing roller 34 can slide inside the slide groove 35. By installing the load-bearing roller 34 at the lower part of the connecting block 21, the pressure of the connecting block 21 on the timing belt 42 can be reduced when placing a heavy workpiece, thereby avoiding deformation of the timing belt 42 and causing the timing belt 42 to rub against the fixing plate 13.
