Description

Technical Field

[0001] The utility model relates to the technical field of film processing, in particular to a device for wiping and cutting powder in the preparation of mildew-proof and fog-proof films. Background Art

[0002] In the packaging of fresh food, vegetables, fruits and frozen food, fog will form inside the packaging bag due to changes in the external environment, large temperature differences or water vapor generated by the metabolism of the packaging contents. This layer of water fog not only reduces the transparency of the film, resulting in consumers being unable to see the true condition of the product, affecting the user's intuitive judgment of the product quality status, but also accelerates the growth and reproduction of microorganisms and molds, ultimately leading to the corruption and deterioration of the packaging contents. The anti-fog and anti-mold polylactic acid film can significantly improve the appearance quality of the packaged product, maintain the humidity of the environment inside the package, and inhibit the growth and reproduction of microorganisms and molds on the surface of the packaging contents, thereby ensuring the quality of the packaging contents and extending the shelf storage period. When anti-fog and anti-mildew film is produced, in order to meet the width requirements, the film edges are generally cut by cutting equipment. However, in actual use of existing cutting equipment, cutting powder is often adsorbed on the cutter by static electricity. When the cutting powder accumulates to the point where the static electricity of the cutter is insufficient to adsorb it, the powder will be carried away by the film during the cutting process, thereby contaminating the appearance quality of the product. In order to avoid this situation, the powder attached to the cutter is usually cleaned frequently by manual labor, which is inconvenient. In addition, the blade of the cutter is extremely sharp, and it is easy to cause accidental injury when cleaning manually. Therefore, a device for wiping cutting powder in the preparation of anti-mildew and anti-fog film is proposed. Utility Model Content
