Description

Technical Field

[0001] The utility model relates to printing equipment, in particular to an in-line printing device. Background Art

[0002] Printing equipment is mainly used to print ink on a substrate to obtain a desired pattern. At present, some printing machines on the market are equipped with a UV module. After printing with UV ink, the ink on the substrate is irradiated by the UV lamp of the UV module to dry and cure the UV ink and improve its gloss and three-dimensional sense. High temperature will be generated during UV irradiation, so a water-cooled roller for the substrate to wind around is arranged at the UV module, and a winding roller is arranged below the water-cooled roller to define the traction path of the substrate, ensuring that the substrate can be largely attached to the water-cooled roller for cooling. And the UV module usually obliquely irradiates the middle position of the substrate attached to the water-cooled roller to obtain a better drying and curing effect. The defect of this structure is that when the printing equipment uses ordinary ink for printing, after printing in one printing unit is completed, it still needs to wind around the water-cooled roller and the winding roller, resulting in a long printing traction path and affecting the printing efficiency. At the same time, when the printing substrate winds around the water-cooled roller and the winding roller, certain friction will inevitably occur, and at this time, the substrate is easily slightly stretched and deformed, especially for some materials with good toughness or plasticity, and this situation is particularly obvious, affecting the printing quality of the product. Summary of the Utility Model

[0003] In view of the deficiencies of the background art, the technical problem to be solved by the present utility model is to provide an in-line printing device for solving the above problems.

[0004] To this end, the present utility model is implemented as follows:

[0005] An in-line printing device, characterized in that: it includes a first frame plate and a second frame plate arranged in sequence. Printing units are arranged on both the first and second frame plates. A water-cooled roller is arranged at the discharge end of the printing unit. A rotating seat is arranged corresponding to the water-cooled roller. A UV module is arranged on the rotating seat. A limiting component is arranged corresponding to the rotating seat. A first winding roller is arranged below the water-cooled roller. A second winding roller is arranged at the feeding end of the second frame plate. The top heights of the water-cooled roller and the second winding roller are the same and are flush with the feeding height and the discharge height of the printing unit.

[0006] The limiting component includes a limiting convex block arranged on the frame. When the rotating seat rotates to drive the UV module to obliquely align with the water-cooled roller, one end of the rotating seat presses tightly on the limiting convex block. A first through hole is arranged on the rotating seat. When the rotating seat rotates to drive the UV module to move above the water-cooled roller, a positioning shaft passes through the first through hole and is inserted into a positioning hole on the frame to realize the limitation of the rotating seat.

[0007] The first and second mounting plates are movably arranged on corresponding bases. The water-cooled roller, the rotating seat, and the first winding roller are arranged on the first mounting frame, and the second winding roller is arranged on the second mounting frame. The first and second mounting frames are fixed on corresponding bases.

[0008] A connection printing device adopting the above technical solution has a simple structure and a reasonable design, and can achieve large-scale production. It can not only achieve UV printing, but also realize the horizontal traction feeding and feeding of the substrate when using ordinary ink for printing. In this way, the traction stroke of the printed substrate and the winding rollers are reduced, the feeding speed of the substrate is effectively improved, the stretching deformation of the substrate during the traction process is reduced, and the printing quality is improved.

[0013] As shown in the figure, a wire-connected printing device disclosed by the present utility model includes a first frame plate 2 and a second frame plate 5 arranged in sequence. Printing units 3 are provided on both the first and second frame plates. A water-cooling roller 9 is provided at the discharge end of the printing unit 3. A rotating seat 10 is provided corresponding to the water-cooling roller 9. A UV module 11 is provided on the rotating seat 10. A limiting component is provided corresponding to the rotating seat 10. A first winding roller 13 is provided below the water-cooling roller 9. A second winding roller 6 is provided at the feeding end of the second frame plate 5. The top heights of the water-cooling roller 9 and the second winding roller 6 are the same and are flush with the feeding height and the discharge height of the printing unit 3. Specifically, the limiting component includes a limiting bump 8 provided on the frame. When the rotating seat 10 rotates to drive the UV module 11 to be obliquely aligned with the water-cooling roller 9, one end of the rotating seat 10 presses tightly against the limiting bump 8. A first through hole 12 is provided on the rotating seat 10. When the rotating seat 12 rotates to drive the UV module 11 to move above the water-cooling roller 9, the positioning shaft passes through the first through hole 12 and is inserted into the positioning hole 14 on the frame to realize the limiting of the rotating seat 10. Further, the first frame plate 2 and the second frame plate 5 are movably provided on the corresponding bases 4. The water-cooling roller 9, the rotating seat 10, and the first winding roller 13 are provided on the first mounting bracket 15. The second winding roller 6 is provided on the second mounting bracket 7. The first and second mounting brackets are fixed on the corresponding bases 4. When controlling the actions of the first and second frame plates to adjust the axial position of the printing unit 3, and further realizing the adjustment of the printing position, it will not drive the water-cooling roller and the UV module to move, ensuring that the subsequent substrate can be normally cooled and the UV irradiation will not be affected.

[0014] The working principle of the present utility model is as follows: When printing with UV ink, control the rotation of the rotating seat 10 to drive the UV module 11 to be obliquely aligned with the water-cooling roller 9. At this time, the printing substrate 1 first passes through the printing unit 3 on the first frame plate 2, and then is pulled around the water-cooling roller 9. When passing through, it is irradiated by the UV module 11 to heat and cure the ink. Then it is pulled to the first winding roller 13, and then passes through the second winding roller 6 and is sent into the printing unit 3 on the second frame plate 5 for further printing; when printing with ordinary ink, control the rotation of the rotating seat 10 to drive the UV module 11 to move above the water-cooling roller 9 to make way. At this time, after the printing substrate 1 passes through the printing unit on the first frame plate 2 for printing, it is directly horizontally pulled through the tops of the water-cooling roller 9 and the second winding roller 6 and sent into the printing unit on the second frame plate 5 for printing.

[0015] With this structure of the present utility model, it can not only realize UV printing, but also realize the horizontal pulling and feeding of the substrate when printing with ordinary ink. In this way, the pulling stroke of the printing substrate and the winding rollers are reduced, the feeding speed of the substrate is effectively improved, and the stretching deformation of the substrate during the pulling process is reduced, improving the printing quality.
