Description

Frame and circular knitting machine with tensioning mechanism

Technical Field

The utility model relates to a circular loom, in particular to a frame with a tensioning mechanism and the circular loom.

Background

Circular knitting machines refer to industrial equipment for knitting cylindrical cloths. In the existing plastic circular loom, a roller assembly is arranged between an upper door ring and a lower door ring to form a rolling track for a shuttle to run, warp threads pass through the door ring assembly, and the shuttle runs along the inner ring of the door ring assembly at a high speed to perform circular motion, so that the warp threads and weft threads are woven in a crossed mode. The weft yarn is usually arranged on the shuttle plate, and warp yarn is input into a host machine after passing through a material passing roller from an external roller and matched with the weft yarn for weaving action. However, in the actual production process, there are usually multiple warp yarns, and because the distance between different warp yarns is far before the warp yarns are drawn into the main machine, part of the warp yarns are tensioned and even broken, but the other part of the warp yarns are still in a loose state, so that the weaving effect is affected.
