Technical Field

[0001] The utility model belongs to the technical field of winding machines, and in particular relates to an upper and lower plastic film winding mechanism for prepreg processing. Background Art

[0002] Prepreg is a composite of a resin matrix and reinforcement made by impregnating continuous fibers or fabrics with a resin matrix under strictly controlled conditions. It is an intermediate material for manufacturing composite materials. Prepreg has the advantages of high strength, low weight, easy processing and cost-effectiveness, making it an ideal choice for many industries. The upper and lower plastic film winding mechanism for prepreg is a device specially used to wind the upper and lower plastic films covering the prepreg during the prepreg production process. This mechanism is designed to ensure that the prepreg is properly protected during processing and improve production efficiency.

[0003] The patent with application number 202221008402.2 discloses a prepreg winding device, which can realize rapid adaptation to cores of different winding diameters. By simple plug-in, the outer diameter of the external support structure related to the rotating rod part can be changed. The whole operation is very simple and there will be no operational errors. In combination with the above application, and in comparison with the existing film winding device, usually in use, when prepregs of different specifications are being processed, the specifications of the plastic films covering their surfaces are also different. When winding, a reel needs to be set on the reel to facilitate the removal of the plastic film after winding. However, the existing reel has a fixed length when in use, and multiple types of reels need to be prepared when winding, which is inconvenient to use, thereby affecting the practicality of the device. For this reason, we propose an upper and lower plastic film winding mechanism for prepreg processing. Utility Model Content

At the same time, the upper film winding roller 104, the lower film winding roller 105 and the prepreg winding roller 106 drive the belt in the belt protection box cover 102 to rotate through the working motor 103 to ensure synchronous rotation and better winding.

[0022] Specifically, the telescopic side cylinder 201 and the roll body 200 are staggered by the protruding limit rod 203 and the strip limit rod 202, and the protruding limit rod 203 and the strip limit rod 202 are also limited by the sliding limit block 204 and the sliding limit groove 205 to ensure the stability of the structure while also better winding.
