Description

Technical Field

[0001] The utility model relates to the field of composite film winding, in particular to a winding structure for packaging composite films. Background Art

[0002] Packaging composite film is a thin film material composed of multiple material layers according to a certain process. Packaging composite film is usually composed of two or more materials, such as plastic, paper, aluminum foil, etc., and is made by bonding, heat sealing and other methods. This composite film has the advantages of multiple materials, can meet different packaging needs, and has the characteristics of moisture resistance, oxygen resistance, high strength, etc. Packaging composite film is a process that bonds different materials together by physical or chemical methods. Common composite film processes include hot pressing composite, wet composite, solvent composite, etc. These processes have their own characteristics and can prepare composite films with different properties and uses. In the production process of composite film, the composite film needs to be wound.

[0003] In a Chinese patent, a packaging composite film winding device is disclosed, and its patent number is CN220078042U. In the packaging composite film winding device of the patent, it includes: a bottom plate, a winding plate is installed on one side of the top of the bottom plate, a winding tube is rotatably installed on the top of the winding plate, the winding motor is fixedly installed on the winding plate, and the winding tube is provided with an easy-to-replace mechanism for facilitating the disassembly and assembly of the winding tube. An anti-deviation mechanism for preventing the composite film from deviating is provided at one end of the top of the bottom plate. The anti-deviation mechanism of the packaging composite film winding device is set, and the first guide roller and the second guide roller guide it, and the anti-deviation blocks on both sides limit the composite film to avoid the deviation during the winding, and the anti-deviation motor drives the positive and negative threaded rods to rotate to ensure the quality of the composite film after winding, so that the two anti-deviation blocks are close to each other or away from each other to adjust the distance between the two anti-deviation blocks, so that composite films of different widths can be limited, thereby improving the practicality of the device.

[0004] The above-mentioned published patents have the following disadvantages:

[0005] In the prior art, after the composite film is produced, a certain amount of dust will adhere to the surface due to static electricity or various reasons, causing the dust to be wrapped around the inner side of the composite film roll along the winding structure, resulting in the packaging composite film still causing contamination of the subsequent items during the packaging process, affecting their normal use.

[0006] In the prior art, since the composite film itself has certain tensile properties, during the winding process, the wound composite film may not be wound tightly enough due to its tensile properties, resulting in some loose composite film inside. Subsequent winding will cause wrinkles.

[0007] In the prior art, during the winding process, the packaging composite film is finally wound on the surface of the winding roller through various components for unified collection. However, during the winding process, the composite film cannot be tightened and wrinkles are generated because the winding effect cannot be guaranteed at some positions. Utility Model Content
