Description

Technical Field

[0001] The utility model belongs to the technical field of yarn feeding anti-blocking devices, and particularly relates to an anti-blocking yarn feeding mechanism. Background Art

[0002] The yarn feed mechanism is used to transport yarn into the weaving area as required. It can control yarn length or maintain consistent yarn tension, ensuring that the fabric meets production requirements. Most yarn feed mechanisms have a yarn break alarm and shutdown function. Depending on their function and use, they can be divided into positive yarn feed mechanisms, semi-negative yarn feed mechanisms, negative yarn feed mechanisms, multi-tone yarn feed mechanisms, and spandex yarn feed mechanisms.

[0003] The yarn feeding mechanism is a mechanism suitable for knitting trolleys. At present, the yarn feeding mechanism still needs to be manually threaded. Due to the complexity of the perforation of the yarn feeding mechanism, the operating burden of the staff is increased. Moreover, after the yarn feeding is completed, the fluff on the surface of the yarn is blocked in the yarn guide eye, making it inconvenient to thread the yarn again. Manual cleaning is required, which is time-consuming and labor-intensive, thereby reducing work efficiency. Utility Model Content
