Description

Technical Field

[0001] The present application relates to the technical field of plastic packaging devices, and more specifically to a plastic packaging machine. Background Art

[0002] Laminators are also called laminating machines. Laminators use the principle of hot pressing to place items such as documents and pictures that need to be laminated in the middle of the plastic film, and use the high temperature and pressure of the machine's rubber roller to press them together. Laminating is widely used in documents, photos, certificates, drawings, cards, labels, menus, brochures, etc. The items after laminating have good sealing, moisture-proof, anti-fouling, anti-wrinkle, anti-scratch, anti-fading and anti-impact properties, so that the items can be preserved for a long time. When the laminator is in use, the plastic film and the plasticized items are put into the laminating inlet of the laminator, and then transported to the hot plastic sealing roller through the inlet film feeding rubber roller. The hot plastic sealing roller then uses hot rolling to seal the plasticized items in the plastic film to form plasticized items. The plasticized items are then rolled and shaped by the outlet shaping rubber roller and then output from the outlet of the laminator. However, in the prior art, the plastic sealing film is prone to curling up or down due to excessive temperature or other reasons, and moves forward along the plastic sealing hot rubber roller, which makes it impossible for the plastic sealing film or the plastic sealed parts to enter the outlet shaping rubber roller. Eventually, the plastic sealing film will be entangled on the plastic sealing hot rubber roller or enter other parts of the machine, causing the machine to be damaged due to its inability to rotate. In response to the above problems, a utility model patent with publication number: CN215156250U discloses a plastic sealing film anti-stuck mechanism of a plastic sealing machine, including an inlet film feeding rubber roller group, a hot plastic sealing rubber roller group and an outlet shaping rubber roller group which are sequentially installed in the housing of the plastic sealing machine from front to back; a preheating mechanism for preheating the plastic sealing film and the plastic sealed parts conveyed by the inlet film feeding rubber roller group is provided between the inlet film feeding rubber roller group and the hot plastic sealing rubber roller group, and the hot plastic sealing rubber roller group preheats the preheated plastic sealing film and the plastic sealed parts The plastic-sealed parts are hot-rolled to form plastic-sealed articles, and an anti-glue-stuck guide mechanism is provided between the hot plastic-sealing rubber roller group and the outlet shaping rubber roller group to prevent the plastic-sealing film on the plastic-sealed articles from curling up or turning down. In this technical solution, the anti-glue-stuck guide mechanism is used to prevent the plastic-sealing film from following the hot plastic-sealing rubber roller group, and ensure that the plastic-sealed articles can smoothly enter the outlet shaping rubber roller group. However, the shaping of the plastic-sealed articles by the outlet shaping rubber roller group is local, the shaping effect is poor, and the anti-glue-stuck guide mechanism is required to cooperate, and the structure is complicated.

Considering that the plastic sealing film may bend or warp due to excessive temperature or other reasons, thereby making the plastic-sealed object not flat enough, affecting the product yield, a shaping mechanism 3 is also installed in the casing 1, the shaping mechanism 3 includes a first shaping plate 31 and a second shaping plate 32, a shaping channel 33 is formed between the first shaping plate 31 and the second shaping plate 32, the inlet of the shaping channel 33 is connected to the outlet of the heat-sealing mechanism 2, and the shaping channel 33 is connected to the outlet of the heat-sealing mechanism 2.

The first shaping plate 31 can move up and down under force to adjust the extrusion force. The first shaping plate 31 and the second shaping plate 32 cooperate to extrude the plastic-sealed objects to make the plastic-sealed objects flat. Since the thickness of the plastic-sealed objects are different, a shaping channel 33 of a certain size is difficult to adapt for use, and the film thickness, molding temperature and molding speed of the molding film during the molding process are different, and the molding effect is also different.
