Description

Technical Field

[0001] The utility model belongs to the technical field of guide roller structure design of a warp knitting machine, and in particular relates to a guide roller guide device of a warp knitting machine. Background Art

[0002] A warp knitting machine is a textile machine used to produce knitted fabrics. Unlike weft knitting machines, warp knitting machines form fabrics by weaving yarns along the length of the fabric (i.e., the warp direction). During the warp knitting process, multiple warp yarns are woven at the same time, which allows for faster production speeds and higher fabric density. The guide roller guide of a warp knitting machine is a device used to guide and adjust the direction of the warp yarns on the warp knitting machine. During the warp knitting process, multiple warp yarns need to be accurately aligned and pass through the weaving mechanism to ensure the quality and weaving efficiency of the fabric. The function of the guide roller guide is to ensure that the warp yarns pass through in the correct position to prevent them from running off or generating unnecessary tension. Guide rollers are usually cylindrical bodies made of metal or plastic with a smooth surface and can be static or dynamic. They are set at key points in the warp yarn path to change or stabilize the direction of the yarn. On some warp knitting machines with complex processes, guide rollers with special devices may also be used, such as guide rollers with automatic alignment or tension adjustment functions, to further improve production efficiency and fabric quality.

[0003] Chinese utility model patent CN220907817U discloses a guide device based on a guide roller of a warp knitting machine, comprising a plurality of conductor structures, which are arranged on the guide roller along the axial linear array of the guide roller. In one of the guide structures, two semicircular ring bodies can be connected through the semicircular ring blocks at both ends to form a cylindrical body and guide a group of yarns through the cylindrical body, and the semicircular ring blocks can limit the yarns; the semicircular ring body contacts the guide roller through the rubber layer, which can effectively avoid excessive relative sliding between the semicircular ring body and the guide roller.

[0004] However, the existing guide roller guide device is slow to replace, which affects the production efficiency, and it is impossible to replace a single guide device body, which greatly increases the production cost. Utility Model Content
