Description

Technical Field

[0001] The utility model relates to the field of packaging material film unwinding, in particular to a packaging material film unwinding device. Background Art

[0002] Packaging film is made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins, and is used for packaging and as a coating layer. Plastic packaging and plastic packaging products occupy an increasingly larger share in the market, especially composite plastic flexible packaging, which has been widely used in the fields of food, medicine, chemical industry, etc. The production of packaging film requires the use of an unwinding device. Most existing unwinding devices directly drag the packaging film during use, causing the packaging film winding roller to rotate freely, which easily causes the packaging film on it to sag. The slack of the packaging film is not conducive to subsequent unwinding and use.

[0003] After searching, the applicant found that a Chinese patent disclosed "A rewinding device for producing packaging material film", and its publication (announcement) number is "CN211643980U". This patent mainly provides a second support frame on the side of the top of the bottom plate away from the first support frame, a mounting frame is provided on one side of the first support frame, a motor is installed on the top of the mounting frame, a rotating shaft penetrating to the top of one side of the first support frame is provided on the side adjacent to the first and second support frames, a connecting frame is provided on the side outside the rotating shaft, and a clamping block is provided on the top and bottom of the connecting frame close to the second support frame. A limiting block is provided on the side of the rotating shaft away from the first support frame, and a raised plate is provided at the bottom of one side of the second support frame. A fixing plate is provided on the side of the top of the bottom plate away from the first support frame, a rotating rod is provided on one side of the top of the fixing plate, and a sliding groove is provided on the side of the top of the fixing plate away from the rotating rod. Support blocks are provided on both sides of the bottom of the bottom plate, one side of one group of the support blocks is provided with a limiting plate, and a fixing rod penetrating to the bottom of the bottom plate is provided on the side of the second support frame away from the first support frame. The utility model solves the problem that the packaging material film is difficult to fix when unwinding. However, the packaging material film is not tight enough when unwinding. Therefore, we propose a packaging material film unwinding device. Utility Model Content
