Description

Technical Field

[0001] The utility model relates to the technical field of winding devices, in particular to a co-extrusion film winding device. Background Art

[0002] In the processing of films, one raw material is extruded onto another film that has been made, or different types of films that have been made are bonded together to form a multilayer film. This product is called a composite film. Most of the materials of composite films are plastics, but paper, metal foil (usually aluminum) or fabric can also be used. The basic requirement of composite films is that there must be good adhesion between layers to ensure the overall mechanical properties of the package. In addition, composite films are mostly used for food packaging. Adhesives must be used in the processing of composite films, and the selection of solvents and bonding processes must meet the corresponding hygiene standards. Co-extruded films have most of the characteristics of composite films, but there is one difference, that is, all layers of co-extruded films are extruded at the same time, so there will be no other non-plastic materials such as aluminum foil and paper. The combination of its product materials is relatively small, and the scope of application is also small, but because the winter-combined layers are combined by hot melt without adhesives, the hygienic safety of co-extruded films for food packaging is relatively reliable. Co-extruded films need to be rolled up after production is completed. In the prior art, a winding device is generally used to achieve the winding of co-extruded films.

[0003] For example, a film winding device with publication number CN210029377U includes a reel, a bracket, a rocker, a disc, and a clamp. The reel is cylindrical, and a clamp groove is arranged on its side wall along its length direction. The bottom of the clamp groove is a semi-cylindrical groove, and the semi-cylindrical groove is arranged coaxially with the reel; the clamp is of the same length as the reel, embedded in the clamp groove, and the two side walls are in contact with the side walls of the clamp groove; the bracket is a frame structure, and a vertical annular clamp ring is arranged at one end of its top and a bottom bracket with an open top at the other end. The top of the bottom bracket is a semicircular part, and the clamp ring is coaxial with the bottom bracket; the disc has the same diameter as the reel and is fixed to the reel and a through hole is arranged in the center; the rocker includes a crank handle, a connecting rod and a rotating shaft connected end to end in sequence, and the connecting rod is perpendicular to the crank handle and the rotating shaft; the rotating shaft of the rocker passes through the semicircular part of the bottom bracket, the through hole of the disc, the semi-cylindrical groove at the bottom of the clamp groove, and the clamp ring in sequence, and then comes out, and the rotating shaft is fixed to the disc. The utility model can solve the technical problem that the membrane is difficult to store in the prior art.

[0004] The above technical solution has some problems in practical application. In practical application, it is not convenient to quickly replace and disassemble the winding core for film winding, and it is not convenient to clamp and fix the film during the replacement process.

[0005] Therefore, it is necessary to invent a co-extrusion film winding device to solve the above problems. Utility Model Content
