Description

Technical Field

[0001] The utility model specifically relates to the technical field of adjustable slitting, in particular to a slitting and winding device with adjustable specifications for the production of fresh-keeping films. Background Art

[0002] Cling film is a plastic packaging product, usually made of ethylene as the masterbatch through polymerization reaction. Cling film can be divided into three categories: the first is polyethylene, referred to as PE; the second is polyvinyl chloride, referred to as PVC; the third is polyvinylidene chloride, referred to as PVDC. It is widely used in food packaging fields such as microwave oven food heating, refrigerator food storage, fresh and cooked food packaging, etc., in family life, supermarkets, hotels and restaurants, and industrial production.

[0003] Due to the different uses of cling film, the cling film is required to have a variety of sizes. However, when cutting the traditional cling film, the cling film can only be cut into one size by a cutter. In this way, when the size of the cling film changes, the equipment needs to be replaced or stopped to adjust the position of the cutter, which greatly reduces the working efficiency of the equipment.

[0004] After searching, Chinese patent publication number CN201821843205.6 discloses a slitting device for cling film production; including a base, a slide, a protective cover, an airbag, and a control panel, wherein an air pump is arranged inside the base, a pneumatic control valve is arranged on the side of the air pump, a controller is arranged above the pneumatic control valve, support legs are arranged on the side of the base, a support plate is arranged above the support legs, a trapezoidal support plate is arranged on the support plate, the slide is arranged inside the support plate, an electric slider is arranged inside the slide, and a push plate is arranged above the electric slider;

[0005] When the structure in the above patent cuts the cling film, the upper telescopic cylinder drives the cutting tool to move to achieve the cutting of the cling film. In this way, during the processing of the cling film, only the cling film of the moving size can be cut; when the size of the cling film changes, the structure in the above patent cannot realize the processing of the cling film, which makes the structure in the above patent have certain limitations;

[0006] In view of the above situation, we provide a slitting and winding device with adjustable specifications for the production of cling film. In this device, the cling film is wound by the transmission of the cling film. During the transmission process, the cling film in the transmission is effectively slit by the cutter in the slitting adjustment component. When adjusting the cutter, the mobile frame is driven to move by the electric push cylinder, so that the second fixed plate installed on the mobile frame drives the third adjustment plate and the fourth adjustment plate to stretch or shrink the multiple first connecting plates and the second connecting plates. In this way, during the adjustment process, the movement of the multiple first connecting plates and the second connecting plates can realize that the multiple adjusters drive the corresponding cutters to move at the same time, which effectively ensures that the distance between two adjacent cutters is the same, and at the same time realizes the multi-knife slitting of the cling film, greatly improving the work efficiency.
