[0002] A UV offset printing device for processing grid-bottom thermal sensitive self-adhesive labels is a printing device that uses ultraviolet light irradiation to quickly cure the ink, and is widely used in the production of self-adhesive labels. UV glue, also known as ultraviolet curable glue, is an adhesive that quickly cures through ultraviolet light irradiation;

The air outlet 54 provided inside the upper end of the preheating box 53 can further enhance the air flow, ensuring uniform cooling of the label paper surface and reducing the risk of local overheating;

[0030] As a further implementation of this solution, the front end of the housing 21 is a through structure, the inside of the housing 21 is hollow, and two installation openings are provided inside the rear end of the housing 21. The filter net 3 and the metal heat absorption roller 65 are on the same horizontal plane, and the winding roller 26 and the lower sealing plate 4 are on the same horizontal plane.

The fixed connection between the fan 51 and the housing 21 ensures a stable supply of cold air, which directly acts on the label paper through the air flow channel inside the housing 21. The connection between the fan 51 and the inner groove slide plate 63 and the communication between the multi-column rotating groove 64 and the air inlet of the fan 51 form an effective air circulation system, further improving the heat dissipation efficiency;

[0032] As a further implementation of this solution, the inside of the hose 52 is communicated with the inside of the preheating box 53. The inside of the preheating box 53 is hollow.

The air outlet 54 penetrates through the upper end of the preheating box 53. The communication design between the hose 52 and the preheating box 53 enables cold air to flow freely between the two, enhancing the cooling effect. The hollow structure of the preheating box 53 and the opening design at the bottom end allow air to enter from the bottom of the preheating box 53, forming an all-round air flow to ensure uniform cooling of the label paper;

[0033] As a further implementation of this solution, the inside of the limited-slip housing 61 is hollow. A rail groove is provided inside the limited-slip housing 61. The top and bottom ends of the inner groove slide plate 63 are fixedly connected with limit sliding pieces. The inner groove slide plate 63 is slidably connected to the inside of the limited-slip housing 61 through limit sliders. The communication design between the hose 52 and the preheating box 53 enables cold air to flow freely between the two, enhancing the cooling effect. The hollow structure of the preheating box 53 and the opening design at the bottom end allow air to enter from the bottom of the preheating box 53, forming an all-round air flow to ensure uniform cooling of the label paper;

[0034] As a further implementation of this solution, the left end of the metal heat absorption roller 65 is a sealing structure, and the right end is a through structure. The heat storage tank 67 is communicated with the heat absorption port 68, and the heat absorption port 68 penetrates the outside of the metal heat absorption roller 65. The shape of the limit ring 66 is a ring. The outside of the metal heat absorption roller 65 fits with the inner side of the multi-column rotating groove 64 opened on the inner groove slide plate 63. The sealing and through structure design of the metal heat absorption roller 65 enables it to effectively absorb and transfer heat, reducing the thermal deformation of the label paper. The communication between the heat storage tank 67 and the heat absorption port 68 and the through design of the heat absorption port 68 form an effective heat transfer path, which helps to dissipate heat quickly.

[0035] Workflow: When printing the label paper to prevent the label paper from deforming due to heat, the label paper is wound around the outside of the unwinding roller 22. The label paper is printed by the printing roller 23. The back of the printed label paper is attached to the upper part of the first guiding roller 24. The UV glue on the label paper is heated and cured by the ultraviolet radiation mechanism 27 emitting ultraviolet rays. The back of the label paper is simultaneously attached to the outside of the second guiding roller 25. The printed label paper is wound up by the winding roller 26. During heat dissipation, the fan 51 is started. The fan 51 sucks air into the multi-column rotating groove 64. At this time, the outside air enters the inside of the housing 21 from the filter net 3 and blows towards the label paper, so as to achieve the purpose of timely cooling the label paper. At the same time, the gas enters the inside of the heat storage tank 67 from the heat absorption port 68. Through the tension of the metal heat absorption roller 65, the outside of the metal heat absorption roller 65 can be closely attached to the label paper, thereby tensioning the label paper and restoring the slightly deformed label paper. At the same time, the metal heat absorption roller 65 absorbs the heat on the label paper. The gas flowing into the heat storage tank 67 through the heat absorption port 68 enters the inside of the multi-column rotating groove 64 from the right end of the metal heat absorption roller 65. Then, the hot air is transported into the inside of the hose 52 by the fan 51, and then blown into the inside of the preheating box 53, and blown out through the air outlet 54 to the printed label paper to achieve the purpose of heating. Thus, when the ultraviolet radiation mechanism 27 heats the label paper, the probability of label paper deformation is reduced. At the same time, under the elastic force of the spring 62, the inner groove slide plate 63 is pushed closer to the label paper. When the winding roller 26 winds up the label paper, due to the label paper being attached to the metal heat absorption roller 65, the metal heat absorption roller 65 rotates under the action of friction. The metal heat absorption roller 65 is rotationally connected to the inner side of the multi-column rotating groove 64 opened on the inner groove slide plate 63 through the limit ring 66, which plays a role in limiting the rotation of the metal heat absorption roller 65 and ensures that the metal heat absorption roller 65 maintains a tight state with the label paper.
