[0002] Self-adhesive label is a kind of self-adhesive label material, which is a composite material made of paper, film or other special materials as the surface, with adhesive coated on the back and silicone-coated protective paper as the base paper. During the production of self-adhesive label, its surface needs to be coated to make the surface of the self-adhesive label smoother and effectively prevent the paper from being scratched or worn.

[0003] A Chinese patent with publication number CN116494556A discloses a laminating device for the production of self-adhesive label rolls, which relates to the technical field of self-adhesive label laminating, and comprises a bottom plate, on which are respectively placed a unwinding roller, a film roller and a winding roller, the unwinding roller and the film roller are respectively located on both sides of the bottom plate, the winding roller is located at one end of the bottom plate, the unwinding roller and the film roller are respectively sleeved with a self-adhesive label roller and a laminating roller, the self-adhesive label roller and the laminating roller are respectively wound with a self-adhesive label body and a film body, the device drives two screw rod sleeves to move simultaneously in a direction close to each other through the rotation of a bidirectional screw rod, and then drives two pressing rollers to move until the two screw rod sleeves respectively press the self-adhesive label body and the film body, and through the setting of the pressing component, not only the self-adhesive label body and the film body can be pressed, but also the self-adhesive label bodies of different thicknesses can be pressed, thereby improving the use range of the laminating device.

[0004] In the existing self-adhesive label laminating device, since the tension on both sides of the laminating film cannot be guaranteed to be the same during the laminating process, the pressure on one side may be greater or less than the other side during laminating. The uneven distribution of pressure will cause the laminating material to produce uneven stress when compounding with the label paper, thereby causing uneven laminating, affecting the appearance quality of the label and causing defects such as corrugations and wrinkles on the label surface. Therefore, a self-adhesive label laminating device is proposed to address the above problems. Utility Model Content

[0026] Working principle: In the existing self-adhesive label laminating device, since it is impossible to ensure that the tension on both sides of the laminating film is the same during the laminating process, the pressure on one side may be greater or less than the other side during the laminating process. The uneven distribution of pressure will cause the laminating material to produce uneven stress when compounding with the label paper, which will further cause the laminating film to be uneven, affecting the appearance quality of the label and causing defects such as ripples and wrinkles on the label surface. Therefore, a self-adhesive label laminating device is proposed to address the above problems. During the laminating process, in order to ensure that the tension of the film is the same during the laminating process, the pressing wheel 8 contacts the surface of the film. When the tension on both sides of the film is the same, the two pressing wheels 8 are in parallel positions, and the extended position of the movable rod 6 is the same, so the pressure at the bottom of the cylinder 9 is the same. At this time, the lifting rod 12 drives the electrode ring 14 to move up to contact with the electrode plate 19, and the indicator light 21 is powered on and becomes brighter; when the tension on both sides of the film is different, the positions of the two pressing wheels 8 are not parallel, and the degree to which the movable rod 6 penetrates into the sleeve 4 is different, resulting in different pressures at the bottom of the cylinder 9. At this time, the electrode ring 14 and the electrode plate 19 are in a staggered state, and the indicator light 21 is powered off and becomes darker, indicating that the tension on both sides of the film needs to be adjusted until the tension on both sides is adjusted to be the same. By setting up a warning mechanism, it is possible to ensure that the pressure on both sides of the film is consistent, avoiding the problem of uneven film coating caused by uneven pressure, making the surface of the label after coating more flat and smooth, avoiding defects such as ripples and wrinkles on the label surface, thereby improving the overall quality and aesthetics of the label;

[0027] During the laminating process, the threaded rod 30 is rotated, and with the cooperation of the rectangular groove 26, the vertical rod 33 drives the lifting block 27 to move downward, and then the clamping roller 28 also moves accordingly. With the cooperation of the supporting roller 23, the clamping force on the laminating material can be adjusted, so that the clamping force can be flexibly adjusted according to the different materials and thicknesses used, so that various types of laminating materials can be processed to meet the needs of different customers. By adjusting the clamping force, it can be ensured that the laminating material and the substrate are closely fitted to avoid defects such as bubbles and wrinkles. Appropriate clamping force can also ensure that the surface after lamination is smooth and flat, thereby improving the overall quality of the product. During the laminating process, the second motor 38 is started, the driving gear 39 rotates, and then the driven gear 37 drives the winding roller 36 to rotate, so that the label after lamination can be towed and wound, which is convenient for subsequent storage and transportation.
