Description

Technical Field

[0001] This utility model relates to the field of flat knitting machines, and in particular to an adjustment structure for rollers. Background Technology

[0002] A flat knitting machine, also known as a horizontal knitting machine, is a type of knitting machinery. It generally refers to a horizontal knitting machine, which uses a horizontal knitting needle bed for knitting. To guide the fabric, flat knitting machines are typically equipped with a roller system. This roller system is installed at the lower end of the fully automatic computerized flat knitting machine frame. When the machine is knitting the fabric, the roller system pulls the end of the fabric away from the knitting position, smoothly unloading it from the machine. During the roller's operation, the fabric may be tighter in the middle and looser at the edges when it is wound onto the roller. Conventional roller systems can cause the fabric to loosen when wound, affecting user operation. In some special cases, the fabric width may vary, and sometimes a single roller system cannot meet the needs or provide a limiting function when winding the fabric. Utility Model Content
