Description

Technical Field

[0001] The utility model relates to the technical field of high-barrier co-extruded film processing, in particular to a high-barrier co-extruded film friction coefficient detection device. Background Art

[0002] High-barrier plastic co-extruded film is made by simultaneously extruding a material with strong gas barrier properties and a polyolefin with strong heat-sealing and moisture barrier properties. It is a multi-layer film. The detection device for conducting relevant detection work on the friction coefficient of high-barrier co-extruded film includes a guide roller, a tensioning roller, and a winding roller for winding and collecting the material. They are used together to achieve auxiliary work in any subsequent process such as extrusion, cutting, winding, plasticization, and curing.

[0003] When using traditional high-barrier co-extruded film friction coefficient testing devices, the adjustability and flexibility of the tensioning roller are not ideal, resulting in poor tensioning operation, affecting the transmission of the co-extruded film, and easily causing problems such as over-tightening and breaking, or over-loosening and causing it to fall.

[0004] Secondly, the winding roller used for the final winding operation in the device lacks a guide and limit component on the surface structure. When the length of the roller is greater than the width of the co-extruded film, the edge of the film will be uneven when winding. Subsequent staff need to manually sort it out, affecting the final quality of the material, which urgently needs to be developed. Utility Model Content
