Description

Technical Field

[0001] The utility model relates to the field of POF packaging film production, in particular to an anti-wrinkle component and POF packaging film production and conveying equipment. Background Art

[0002] POF packaging film is a thin film material used to package and protect products. Packaging film is widely used in food packaging, pharmaceutical packaging, industrial product packaging and other fields. Its main functions include protecting products from external environmental influences (such as moisture and pollution), extending the shelf life of products, and improving the appearance and market appeal of products. Different types of packaging films have different characteristics, such as transparency, flexibility, heat resistance, etc., to meet the needs of different products.

[0003] After searching, a Chinese patent with publication number CN221190957U discloses an anti-wrinkle component and POF packaging film production and conveying equipment; the invention comprises a roller provided on the surface of a rotating shaft, a positioning hole provided on the arc surface of the rotating shaft, a telescopic plate provided on the surface of the rotating shaft, a telescopic rod provided inside the telescopic plate, a spring sleeved on the surface of the telescopic rod, a connecting block sleeved on the surface of the roller shaft, a fixing plate provided on the surface of the connecting block, a groove provided on the surface of the fixing plate, a sliding groove provided on the surface of the groove, a screw rod inserted through the surface of the groove, a baffle provided on the surface of the screw, and a threaded hole provided on the surface of the groove. The beneficial effect is that when the screw rod is rotated in the threaded hole, the screw rod will slowly move in the threaded hole, and the movement of the screw rod will drive the telescopic plate provided on the second rotating shaft to move in the sliding groove, so that the second roller shaft replaces the first roller shaft to transport the POF packaging film. Under the support of the second roller shaft, the POF packaging film is tensioned during transportation to prevent the POF packaging film from wrinkling during transportation. The structure is simple and easy to operate, which is conducive to improving its use effect.

[0004] Although the above scheme can prevent the packaging film from wrinkling, there are still some shortcomings during use. For example, in actual use, the packaging film needs to be controlled by the staff to be tightened, and it is difficult to automatically tighten the packaging film after the packaging film becomes loose, so that the packaging film is prone to wrinkles.

[0005] To this end, we propose an anti-wrinkle component and POF packaging film production and conveying equipment to solve the above problems. Utility Model Content
