Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Embodiment 1: This embodiment Figure 1-Figure 3 and Figure 6 As shown, in order to solve the problem that the height of the existing device is fixed and difficult to change, the working process of the lifting structure of the packaging carton UV reverse printing and curing device is disclosed, and the effect of the height adjustment of the device within a certain range is achieved. The specific contents are as follows:

[0035] A driving motor 21 and a rotating shaft 22 are arranged inside the lifting structure. The driving motor 21 is fixedly mounted on the upper end of the base 1. The rotating shaft 22 is rotatably mounted inside the base 1. Two sets of sliding plates 23 are threadedly mounted on the outer side of the rotating shaft 22. The sliding plates 23 are slidably connected to the base 1. A support rod 24 is rotatably mounted on the upper end of the sliding plate 23. The upper end of the support rod 24 is rotatably connected to the curing table 4.

[0036] Four groups of the support tubes 2 and the moving tubes 3 are arranged symmetrically about the vertical center axis of the base 1 , and the support tubes 2 and the moving tubes 3 are arranged corresponding to the support rods 24 .

[0037] When using the packaging carton UV reverse printing and curing device, first place the device at the position where it needs to work. After placing the device at the required position, the height of the device can be adjusted. During the height adjustment of the device, the drive motor 21 needs to work, and a pulley structure is provided between the output end of the drive motor 21 and the outer side of the rotating shaft 22, so that the drive motor 21 can drive the rotating shaft 22 to rotate through the pulley structure. During the rotation of the rotating shaft 22, the two sets of sliding plates 23 will slide inside the base 1, and during the movement of the sliding plates 23, the curing table 4 will move up and down, and during the up and down movement of the curing table 4, the moving cylinder 3 will move up and down on the outer side of the supporting cylinder 2. After the curing table 4 moves to the required height, the drive motor 21 can stop moving. At this time, the device can be limited to this height, so that the device can be used in different situations, which effectively improves the applicability of the device.

[0038] Embodiment 2: This embodiment is as follows Figure 1-Figure 2 and Figure 4-Figure 5 As shown, in order to solve the problem that the existing device can only perform centering adjustment for cartons of the same size, the working process of the adjustment structure of the UV reverse printing and curing device for packaging cartons is disclosed, and the effect that the device can perform centering adjustment for cartons of different sizes is achieved. The specific contents are as follows:

[0039] An adjustment structure is installed on the upper end of the curing station 4, and the adjustment structure can achieve the effect of the device correcting and processing cartons of different sizes;

[0040] A support plate 10 and a limit rod 11 are provided inside the adjustment structure. The support plate 10 and the limit rod 11 are fixedly installed on the outside of the curing table 4, and two groups of the support plate 10 and the limit rod 11 are symmetrically arranged front and back about the vertical center axis of the curing table 4.

[0041] A moving plate 12 is slidably mounted on the upper end of the support plate 10, and the moving plate 12 is slidably connected to the limiting rod 11, and two sets of positioning rods 13 are slidably mounted inside the moving plate 12, and a driving rod 14 is rotatably mounted inside the positioning rod 13;

[0042] A connecting rod 19 is rotatably mounted on one side of the moving plate 12 close to the conveying mechanism 5 , and a mounting piece 20 is rotatably mounted on one end of the connecting rod 19 away from the moving plate 12 , and the mounting piece 20 is sleeved on the outer side of the driving rod 14 .

[0043] When using the UV reverse printing and curing device for packaging paper boxes, it is necessary to ensure that the paper box moves in the center of the upper end of the conveying mechanism 5, so as to avoid the deflection of the pattern printing on the upper end of the paper box. During the movement of the conveying mechanism 5, the movement state of the paper box will be adjusted by two sets of guide plates 17. When adjusting for paper boxes of different sizes, it is necessary to change the positions of the two sets of guide plates 17.

[0044] In the process of adjusting the position of the guide plate 17, it is necessary to rotate the driving rod 14. During the rotation of the driving rod 14, the two sets of mounting parts 20 will move on the outside of the driving rod 14. During the movement of the mounting parts 20, the moving plate 12 will be pulled to move through the connecting rod 19. During the movement of the moving plate 12, the guide plate 17 will be driven to move through the fixing part 15 and the moving part 16. At this time, the position adjustment process of the guide plate 17 can be completed, so that the device is convenient for centering when printing paper boxes of different sizes, further improving the applicability of the device.

[0046] A fixing part 15 is fixedly installed on one side of the moving plate 12 close to the conveying mechanism 5, and a moving part 16 is slidably installed inside the fixing part 15, and a guide plate 17 is fixedly installed on one end of the moving part 16 away from the fixing part 15, and a supporting spring 18 is sleeved on the outer side of the moving part 16 and the fixing part 15.

[0047] When using the UV reverse printing and curing device for packaging paper boxes, it is necessary to adjust the paper box to the center through the guide plate 17. During the process of the guide plate 17 adjusting the paper box, the guide plate 17 will be subjected to the reverse force of the paper box. At this time, the guide plate 17 will move away from the paper box and adjust the paper box to the center. During the movement of the guide plate 17, the moving part 16 will slide toward the inside of the fixed part 15. During the movement of the moving part 16, the support spring 18 will be squeezed and the support spring 18 will be contracted, thereby preventing the guide plate 17 from squeezing the paper box too much during the process of centering the paper box, causing damage to the paper box, thereby protecting the paper box and increasing the overall practicality.

[0048] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
