Description

Technical Field

[0001] The utility model relates to a yarn feeder, belonging to the technical field of textile auxiliary equipment. Background Art

[0002] A yarn feeder is a device used in a textile machine to transport yarn to the textile machine. Its main function is to ensure that the yarn is supplied to the textile machine at a uniform speed and tension.

[0003] For example, the Chinese utility model patent with the publication number CN218404612U proposes "a yarn feeder for a flat knitting machine", which includes a thread loading frame, and also includes a threaded ring and a limiting cylinder. The top of the thread loading frame is detachably installed with a top plate, the side wall of the top plate is detachably installed with a connecting plate, the bottom of the connecting plate is detachably installed with a limiting cylinder, the side wall of the limiting cylinder is threadedly connected with a threaded seat, a yarn adjusting component is detachably installed between the inner walls of the thread loading frame, and symmetrically arranged clamping grooves are formed on the inner wall of the thread loading frame, and a yarn disc is arranged between the clamping grooves. The yarn adjusting component includes a limiting frame, a lead screw, a sliding block, a driving motor, a connecting block and a threading ring. The limiting frame is detachably installed between the inner walls of the thread loading frame, and a horizontal sliding groove is formed at the bottom of the limiting frame. It can horizontally move and adjust the position of the yarn to avoid the yarn rubbing against the inner wall of the yarn outlet and breaking, which affects the strength of the fabric.

[0004] However, in the above patent, the yarn disc is arranged in a group of symmetric clamping grooves in the thread loading frame. When replacing the yarn disc, the yarn roller needs to be taken out of the clamping groove. Once there is too much yarn on the yarn disc, it will be blocked by the top plate when the yarn disc needs to be slid in from the top of the clamping groove, making the process of replacing the yarn disc somewhat inconvenient. Therefore, the utility model proposes a yarn feeder to solve the above problems. Summary of the Utility Model
