Description

Technical Field

[0001] The utility model relates to the technical field of new polymer packaging materials, and particularly relates to a slitting and packaging device for PE protective films. Background Art

[0002] A PE protective film is a layer of film coated on plastic products to avoid surface contamination, scratches or damage during processing, transportation and storage. The slitting of the PE protective film can provide accurate specifications according to user requirements. At the same time, during the slitting and unwinding process, the large roll of composite film composite during the previous extrusion composite process can be inspected again to check for quality problems and improve the quality of the PE protective film.

[0003] After retrieval, the existing patent (publication number: CN219771350U) discloses a slitting and packaging device for PE protective films, including a packaging table. The front of the top of the packaging table is provided with a slitting small roll. A separation plate is fixedly connected to the front of the packaging table. Fixed brackets are fixedly connected to the fronts of both sides of the packaging table. Inner lining rings are fixedly connected to one sides of the fixed brackets respectively. Pressing plates are fixedly connected to the middle parts of both sides of the packaging table. A cover plate is movably connected to the back of the top of the packaging table. A fixed tube is fixedly connected to the front of the cover plate. A front support tube is movably sleeved on the front of the inner bottom of the rear part of the packaging table. By placing the winding film in the packaging table, when winding the slitting small roll, the winding film will not move its position during rolling. After the pulled-out winding film packages a group of slitting small rolls, the winding film covering the packaging table is still available for packaging the next group of slitting small rolls, making the packaging more convenient and improving the packaging efficiency.

[0004] However, in the above solution, it is difficult to effectively fix and flatten the protective film.
