Description

Technical Field

[0001] This utility model relates to the field of PVC film production technology, specifically a winding device for PVC film production. Background Technology

[0002] PVC film, or polyvinyl chloride film, is a thermoplastic film made from polyvinyl chloride resin as the main raw material, with the addition of plasticizers, stabilizers, fillers and other auxiliary materials, and processed through calendering, extrusion, blow molding and other processes. It has good chemical corrosion resistance, flame retardancy, abrasion resistance and electrical insulation, and is widely used in packaging, decoration, building materials, electronics, medical and other fields. Its performance and uses can be adjusted according to the type and amount of additives.

[0003] Authorization announcement number CN221939682U discloses a film winding device for PVC composite film production. The technical solution is as follows: "It includes a support base plate, with a winding roller mounted above one end of the support base plate and a feeding roller mounted above the other end. Rotating support seats are provided at both ends of the winding roller and the feeding roller. A drive motor is mounted on the outer side of the rotating support seat at one end of the winding roller." The beneficial effects are: it can monitor the pressure applied to the PVC composite film by the tensioning roller in real time, and adjust the height of the tensioning roller according to the actual tension changes, thereby ensuring the stability of the tension during PVC composite film winding, improving the quality of the finished product, and making it suitable for widespread use.

[0004] The above-mentioned technical solutions have the following drawbacks: they lack a cleaning structure for PVC film. During the placement and production process, dust will adhere to the outer wall of the PVC film, which will affect the appearance quality of the product, reduce its transparency and gloss, and thus affect the customer's visual experience and product grade. Moreover, in the subsequent printing, lamination and heat sealing processes, dust particles can easily lead to poor processing or even damage to equipment, increasing production costs and maintenance expenses. Therefore, a winding device for PVC film production is proposed to solve the problems mentioned above. Utility Model Content
