Description

Technical Field

[0001] The utility model relates to the field of plastic film production, in particular to a traction, positioning and edge cutting device for food packaging plastic film. Background Art

[0002] Food packaging film is a polymer material used to wrap the surface of food, mainly to isolate and decompose the entry of microorganisms, bacteria and foreign pollutants, and prevent and prolong the food spoilage. Due to the different packaged foods, it is usually necessary to trim the plastic film with a wider width to avoid waste of resources caused by excess plastic film when packaging.

[0003] After searching, the applicant found that a Chinese patent disclosed "a degradable plastic film traction positioning and trimming device", and its publication (announcement) number is "CN216732627U". This patent mainly uses a hydraulic rod to drive the fixed box to move downward, so that the slice can accurately trim the plastic film. At the same time, the torsion plate drives the rotation of the rotating rod and the first gear, and drives the two second gears and the screw to rotate, so as to facilitate the screw sleeve, the folding plate and the slice to move to the opposite or opposite side, so that plastic films of different widths can be trimmed. At the same time, the plastic film is fixed by the extrusion wheel to prevent the plastic film from loosening during the trimming process, which solves the problem that the current trimming device cannot trim plastic films of different sizes;

[0004] The above patent has a certain degree of accommodation for cutting plastic films and can cut plastic films of different sizes. However, in reality, the plastic films that need to be cut are all in roll form. Therefore, after cutting one roll of plastic film, another roll of plastic film needs to be replaced for cutting. After the above device has cut the plastic film, it is necessary to roll the uncut plastic film onto the plastic film barrel, which delays working time and reduces working efficiency.
