Detailed Description

The present invention will be further described with reference to the accompanying drawings.

The mechanical device for printing the laminating films as shown in the attached figures 1 to 7 comprises a laminating machine 1 and a dust and moisture removing device 2; the dust removal and dehumidification device 2 is arranged above the paper feeding table 11 in a spanning mode; the dust removal and dehumidification device 2 comprises an air inlet pipeline 21 and an air outlet pipeline 22; the air inlet pipeline 21 and the air outlet pipeline 22 are respectively located at two sides of the dust removal and dehumidification device 2, and a hot air flow is formed between the air inlet pipeline 21 and the air outlet pipeline 22.

The laminating machine 1 comprises a paper feeding table 11, a paper conveying device 13, a conveying belt 14, a film conveying device 15, a gluing roller 16, a pressing roller 17, a cutting device 18 and a product output belt 19; the paper feeding table 11 comprises a circular rotary lifting device 111, and the rotary lifting device 111 is divided into two symmetrical areas; after the paper stack 12 is placed in one of the areas of the rotary lifting device 111, the area rotates to the lower part of the dust and moisture removing device 2, and the lower semicircular lifting platform 112 lifts the paper stack 12 until the uppermost end of the paper stack 12 is slightly lower than the pipe opening of the air inlet pipe 21.

At this time, the mechanical device starts to operate, and the air inlet pipeline 21 blows hot air flow; the hot air flow can play a drying role on the printing ink, so that the possibility of bubbles after the paper and the plastic are compounded is reduced; meanwhile, the hot air flow can take away dust, powdered ink and other foreign matters on the surface of the printing paper, so that the paper surface is cleaned, and the quality of the paper-plastic composite product is improved; then, the paper conveying device 13 conveys the topmost sheet of the paper stack 12 to the conveyor belt 14, and the semicircular lifting platform 112 drives the paper stack 12 to ascend to compensate the height of the conveyed sheet; the conveyor belt 14 is arranged with a differential speed and is provided with a height limiting device, so that the paper sheets can be closely arranged end to end one by one after passing through the conveyor belt 14.

After the film is transported by the film conveying device 15 and coated by the coating roller 16, the film and the paper enter the laminating roller 17 together to realize laminating of the paper and the film; and then the cutting device 18 cuts the paper-plastic composite product, and the paper-plastic composite product can be transported out along with the product output belt 19.

The basic working principle of the laminating machine 1 is as above, and the dust removal and dehumidification device 2 also comprises some detailed designs; the outer edge of the air inlet pipeline 21 is provided with an air heating device 23 in a matching manner, so that the air inlet pipeline 21 connected with the positive pressure air path can output hot air flow, the air in the pipeline can be uniformly heated, and the output of the hot air flow is more stable.
