Description

Technical Field

[0001] The utility model belongs to the technical field of laminating, in particular to a hot stamping laminating device for label printing. Background Art

[0002] Label printing lamination refers to the process of laminating a transparent plastic film onto the surface of a printed product through hot pressing to protect it and increase its gloss. Existing hot stamping lamination devices for label printing, such as the hot stamping lamination device for label printing disclosed in application number CN202321428924.2, can improve the bonding effect between the label and the film by providing a hot laminating mechanism, and an anti-warping mechanism is provided, which is beneficial to pressing the laminated label and reducing the occurrence of label warping.

[0003] However, in actual use, the existing hot stamping laminating device only relies on a group of pressing rollers and a group of electric heating rollers for laminating. After the lamination is applied, the glue can only be cured by natural drying, which is inefficient. In addition, during re-pressing, the glue is likely to flow out due to not yet solidified, affecting the appearance of the label. In severe cases, it may cause slippage between the lamination and the label. In particular, the existing lamination device uses multiple groups of expansion rollers, which has a complex structure and is cumbersome to operate when adjusting tension and pressing. Therefore, we propose a hot stamping lamination device for label printing to solve the above problems. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a hot stamping and laminating device for label printing, which effectively solves the problem that the existing hot stamping and laminating devices for label printing have low efficiency in natural drying and curing after lamination, and are prone to glue outflow or misalignment and sliding during re-pressing, and solves the problems of complex structure and cumbersome operation.

[0005] The technical solution adopted by the utility model is as follows: The utility model proposes a hot stamping laminating device for label printing, comprising a bottom plate, a side plate, a laminating winding roller and a label winding roller, the side plate being vertically fixed to the bottom plate, the laminating winding roller being rotatably connected to the inner wall of the side plate, the label winding roller being rotatably connected to the inner wall of the side plate and arranged below the laminating winding roller, a tensioning laminating mechanism and a glue coating tube being provided on the inner wall of the side plate, and a re-pressing and curing mechanism being provided on the bottom plate.

[0006] As an improvement of the present scheme, the tensioning and laminating mechanism includes a tensioning plate, a tensioning guide roller, a slide rail, a slider and an electric heating roller. The tensioning plate is rotatably connected to the inner wall of the side plate, the tensioning guide roller is rotatably connected to the tensioning plate, the slide rail is fixed to the inner wall of the side plate, the slider is slidably connected to the slide rail, and the electric heating roller is rotatably connected to the slider.

[0007] As an improvement of this solution, a tensioning motor is provided on the outer wall of the side panel, and the output shaft of the tensioning motor passes through the side panel and is connected to the tensioning plate, a pipe joint is provided on the side wall of the side panel, and the pipe joint passes through the side panel and is connected to the rubber coating tube, a compression spring is provided on the bottom plate, and the other end of the compression spring is connected to the bottom of the slider.

[0008] As an improvement of the present scheme, the re-pressing and curing mechanism includes a heating and curing plate, an electric heating coil, a rocker arm and a re-pressing roller. The heating and curing plate is fixed on the bottom plate and arranged below the electric heating roller. The electric heating coil is arranged at the top of the heating and curing plate. The rocker arm is rotatably connected to the inner wall of the side plate. The re-pressing roller is rotatably connected to the rocker arm and arranged above the heating and curing plate.

[0009] As an improvement of the present scheme, a card slot is provided on the rocker arm, a damper is rotatably connected to the inner wall of the side panel, a U-shaped card is provided at the other end of the damper, and the U-shaped card is plugged and connected to the card slot, a rewinding roller is rotatably connected to the inner wall of the side panel, and the rewinding roller is arranged on one side of the heating and curing plate.

[0011] As an improvement of the present solution, the heating and curing plate is arranged in a U-shaped thin plate, and the electric heating coil is arranged in an S-shape.

[0012] The beneficial effects achieved by the utility model using the above structure are as follows:
