Description

Technical Field

[0001] The utility model relates to the technical field of laminating machines, in particular to a laminating machine for printing. Background Art

[0002] Laminating technology is widely used in the printing industry, mainly to improve the appearance quality and durability of printed products. Traditional laminating machines usually include several main components such as conveying part, coating part, drying part and winding part. These machines achieve the effect of protecting and beautifying the surface of printed products by covering the film on the surface of printed products.

[0003] Existing laminating machines usually use the following structure to achieve the laminating function: Conveying part: used to convey printed materials and films to ensure that the two can be accurately docked. Coating part: the glue is evenly applied on the surface of the film or printed materials through the coating device to ensure the quality of the lamination. Drying part: the coated film and printed materials are dried through the heating device to ensure that the glue is fully cured. Winding part: the finished product after lamination is rolled up or cut for subsequent processing. However, during the conveying process of the existing laminating machine, the film and printed materials are prone to deviation, resulting in inaccurate lamination, affecting the appearance quality of the final product. At the same time, the existing laminating machines can often only cope with printed materials of a specific thickness and cannot flexibly adapt to materials of different thicknesses, which limits their scope of application. In this regard, in response to this technical problem, the present application proposes a laminating machine for printing. Utility Model Content

[0028] Specifically, firstly, unscrewing the bolt of the expansion roller 5 can make the expansion roller 5 and the rotating head 3 rotate, and then the film material and the printed material are sleeved on the outer walls of the two upper expansion rollers 5, and then the baffle 6 is pushed to cooperate with the spring three 4 and the positioning shaft 19 to clamp the baffle 6 in a suitable position, so that the film material and the printed material can be clamped in a suitable position on the outer wall of the expansion roller 5, and then the film and the printed material are passed around the guide roller 7, and then passed between the rolling roller 8 and the bottom roller 9, and then wrapped around the outer wall of the collecting sleeve placed on the outer wall of the lower expansion roller 5, and finally the laminating machine is started to laminarize them. When the film material and the printed material are clamped in a suitable position through the baffle 6, the positions of the film material and the printed material are aligned, and the film and the printed material in the subsequent printed material lamination can be more comprehensively and accurately laminarized, so as to improve the efficiency of laminating.
