Description

Technical Field

[0001] The utility model relates to the technical field of plastic film folding, and more specifically, to a plastic film folding device. Background Art

[0002] Plastic film is a kind of film material widely used in packaging, agriculture, construction and other fields. Its main advantages are light weight, high strength, good transparency, excellent barrier properties, etc. In practical applications, in order to improve the strength, rigidity and stability of plastic film, it is usually necessary to fold its edges, that is, fold the edges of the plastic film to a certain width and angle to form a reinforced edge structure. Folding can not only increase the thickness and strength of the plastic film and prevent the edge from tearing or breaking, but also improve the feel and appearance of the plastic film, and improve its beauty and texture. In addition, folding can also facilitate the subsequent processing and use of the plastic film, such as heat sealing, bonding, and sewing. In order to realize the automatic and continuous folding of plastic film, special folding devices are usually used, such as folding machines, folding devices, etc. These folding devices fold the edges of the plastic film into a predetermined shape and angle through a series of mechanical transmission and pressure, so as to obtain an ideal folding effect. However, in actual production, due to the different parameters of the plastic film, such as material, thickness, width, and different requirements of the folding process, it is often necessary to replace different folding tools or adjust the folding angle to adapt to different folding requirements. For example, for thinner or softer plastic films, smaller pressure and narrower folding width are required, while for thicker or harder plastic films, larger pressure and wider folding width are required. For another example, for different folding shapes, different shapes of folding molds or pressing plates are required. However, the existing plastic film folding devices usually use fixed folding tools and pressure mechanisms, which cannot flexibly adapt to different folding requirements, resulting in difficulty in ensuring folding quality and efficiency, limiting its scope of application and practicality.
