Example 2:

[0035] Based on the first embodiment, the specific working principle is as follows:

[0036] The invention relates to a continuous UV electroplating mechanism for a loose powder box based on a screw-in installation. First, UV coating is evenly applied to the outer side of the loose powder box. The loose powder box after coating is installed on the outer side of three friction blocks 16. Since the spring 12 is located on the top of the sliding sleeve 11, the spring 12 will drive the sliding sleeve 11 to slide on the outer side of the fixed shaft 9, so that the sliding sleeve 11 and the fixed block 13 are close to each other. In the process of the fixed block 13 sliding downward, since the distance between the fixed block 13 and the fixed shaft 9 is greater than the distance between the moving block 14 and the fixed shaft 9, the fixed block 13 drives the driving rod 15 to slide downward, and the middle of the driving rod 15 will be The driving rod 15 slides outside the fixed block 13, and at the same time, the driving rod 15 rotates around the moving block 14 in a direction away from the fixed shaft 9, so that the driving rod 15 drives the friction block 16 away from the fixed shaft 9. The three friction blocks 16 move toward the fixed shaft 9 at the same time, so that the three friction blocks 16 are tightly fitted with the inner side of the loose powder box, thereby fixing the loose powder box. At the same time, the distance between the sliding sleeve 11 and the fixed block 13 can be adjusted, and the distance between the friction block 16 and the fixed shaft 9 can be adjusted, thereby adjusting the outer diameter of the annular structure formed by the three friction blocks 16, so that loose powder boxes of different sizes can be installed and fixed;

[0037] When the outer sides of the plurality of friction blocks 16 are all fixed to the powder box, the door 3 is closed, so that the device is in a Figure 2 In the state shown, the top and bottom of the inner side of the door 3 will fit together with the two sealing gaskets 20 inside the curing chamber 2, and the sides of the door 3 and the curing chamber 2 will fit together, so that a sealed ring is formed inside the curing chamber 2. At this time, the guide rails 19 located on the inner sides of the curing chamber 2 and the door 3 will form a complete circular structure, and multiple external curing lamps 18 will surround the sealing structure formed by the curing chamber 2 and the door 3.

[0038] When the door 3 is closed, the motor 4 is started to drive the drive shaft 5 to rotate. The rotation of the drive shaft 5 drives the rotating rod 7 on the outside of the connecting ring 6 to rotate around it. Since the interior of the mounting hole 8 is rotatably connected to the fixed shaft 9, the rotating rod 7 will drive the fixed shaft 9 to rotate around the drive shaft 5. At this time, the driven wheel 10 will rotate inside the complete circular ring structure formed by the guide rail 19, so that the driven wheel 10 drives the fixed shaft 9 and the friction block 16 on the outside thereof to rotate with it. While the fixed shaft 9 rotates around the drive shaft 5, the fixed shaft 9 is driven by the driven wheel 10 to rotate, causing the powder box fixed on the outside of the friction block 16 to rotate while rotating around the drive shaft 5. During the rotation of the powder box, it will be illuminated by the internal curing lamp 17 and the external curing lamp 18 at the same time. The rotation of the powder box allows the internal curing lamp 17 and the external curing lamp 18 to irradiate the powder box without blind spots, thereby accelerating the curing speed of the UV coating on the outside of the powder box. The uniform irradiation of the UV coating by the internal curing lamp 17 and the external curing lamp 18 improves the curing quality.
