Usually, the plastic layer uses flat woven cloth with polypropylene or polyethylene as the base material, and the kraft paper uses refined composite special kraft paper. It has the characteristics of high strength, good waterproofness and beautiful appearance. It is one of the most popular packaging materials and is widely used in plastic raw materials, cement, feed, chemical industry, fertilizer and other industries. The laminating machine can be divided into two categories: instant laminating machine and pre-coating laminating machine. It is a special equipment for paper, board and film mounting. After being pressurized by rubber roller and heating cylinder, it is combined to form a paper-plastic product.

[0003] In the prior art, there is a double-sided laminating machine in application number CN201821247694.9, which includes a base, and a frame is arranged on the base; the utility model simultaneously arranges an upper laminating mechanism and a lower laminating mechanism on the frame, and adopts the online double-sided laminating operation of the electronic paper at the same time, which can greatly improve the production efficiency and reduce the production cost. However, the existing laminating machine has the following problems: 1. When the existing laminating machine is laminating the product, it is difficult to make the paper or film compactly cover the product, resulting in a not very ideal covering effect, and the paper or film is partially non-adhesive; 2. When the film on the original film shaft is used up, the film on the original film shaft needs to be replaced. Since the installation method between the original film shaft and the machine body is relatively cumbersome, it is time-consuming and laborious to disassemble.

[0026] The effect achieved by the entire embodiment 1 is that, during coating, the staff starts the fan 10, and the nozzle 7 begins to suck the surrounding air into the interior. Since the nozzle 7 is directed toward the contact point of the coating, the nozzle 7 will suck the dust on the film into the interior, and then enter the air outlet pipe 9 through the fixed pipe 6, and finally enter the collection box 5, blocked by the filter plate 11, and remain in the collection box 5. When there is too much dust, the staff starts the first electric telescopic rod 14, and the telescopic end of the first electric telescopic rod 14 stretches to push the partition 17 to move. When the partition 17 moves to the other side of the interface between the air outlet pipe 9 and the collection box 5, the air contacts the collection box 5 and the filter plate 11 from the other side of the partition 17. At the same time, the second electric telescopic rod 16 is started, and the baffle 15 moves to the other side of the collection box 5. At this time, the staff can open the door 8 of the collection box 5 where no air passes, clean the dust inside and reset it. In this way, the dust can be cleaned without stopping the machine, thereby improving production efficiency.

[0027] Embodiment 2, as Figure 1-Figure 5 As shown, further, a slide groove 18 is opened on the opposite side of the two fixed plates 3, and springs 19 are fixedly installed on the inner walls of the two slide grooves 18. The first storage seat 20 and the first slide plate 28 are fixedly installed on the bottom of the two springs 19 respectively.

When there is too much dust, the staff starts the first electric telescopic rod 14, and the telescopic end of the first electric telescopic rod 14 stretches to push the partition 17 to move. When the partition 17 moves to the other side of the interface between the air outlet pipe 9 and the collection box 5, the air contacts the collection box 5 and the filter plate 11 from the other side of the partition 17. At the same time, the second electric telescopic rod 16 is started, and the baffle 15 moves to the other side of the collection box 5. At this time, the staff can open the door 8 of the collection box 5 where no air passes, clean the dust inside and reset it. In this way, the dust can be cleaned without stopping the machine, thereby improving production efficiency. During lamination, when the film on the laminating shaft 26 contacts the packaging bag, the packaging bag pushes the laminating shaft 26 to rise, and the laminating shaft 26 drives the second storage seat 24 and the second slide 29 to rise, thereby driving the first storage seat 20 and the first slide 28 to rise, and the spring 19 is compressed, so that packaging bags of different thicknesses can be laminated.

[0035] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
