Description

Technical Field

[0001] This utility model relates to the field of circular knitting machine technology, specifically a yarn guiding mechanism for a large circular knitting machine that prevents yarn wear. Background Technology

[0002] The yarn guiding mechanism of a circular knitting machine is mainly used to transport the yarn to the loop forming system according to specific tension requirements, ensuring a stable yarn supply during the knitting process. This mechanism is widely used in the production of products with high requirements for yarn tension stability, such as high-elastic fabrics and sportswear, and ensures the uniformity and elasticity of the fabric through precise yarn guiding.

[0003] Chinese patent CN222700546U discloses a yarn guiding mechanism for a circular knitting machine designed to prevent yarn wear. The mechanism includes a fixed base, a connecting plate, guide wheels, and a yarn guide nozzle. The connecting plate is mounted on the fixed base, while the guide wheels and yarn guide nozzle are mounted on the connecting plate. The yarn guide nozzle has a first channel, a second channel, and a boss. The inlets of the first and second channels are located on the front of the yarn guide nozzle, the outlet of the first channel is located on the back of the yarn guide nozzle, the outlet of the second channel is located on the bottom surface of the yarn guide nozzle, and the boss is located on the front of the yarn guide nozzle. In this yarn guiding mechanism, the first and second yarns are respectively threaded through the first and second channels of the yarn guide nozzle and fed into the knitting needle hook, with a large spatial overlap angle. After being guided by the guide wheels, the spandex yarn passes under the boss of the yarn guide nozzle, and the boss precisely feeds the spandex yarn into the knitting needle hook. Furthermore, the spandex yarn does not accumulate dust, improving the quality of the fabric weaving.

[0004] The aforementioned mechanism has the effects of precise yarn feeding and dust prevention. However, when the existing device is in use, the yarn is transported at a high speed, which causes great wear on the yarn. In order to control the yarn tension, the mechanism usually needs to have more precise adjustment functions. Therefore, it is necessary to provide a yarn guiding mechanism for a circular knitting machine that prevents yarn wear. Utility Model Content

[0012] Preferably, both the transverse limiting seat and the longitudinal limiting seat are provided with two protruding posts, and the first adjusting rod and the second adjusting rod are respectively threaded onto the longitudinal guide seat and the fixed seat.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1) The yarn guiding mechanism of this circular knitting machine that prevents yarn wear places the yarn between four pulleys through the guide groove, and controls the threaded rod to make the upper and lower pulleys move up and down relative to the limit frame under the support of the mounting base, so that the yarn is suspended inside the guide groove, ensuring that the yarn does not directly contact the hook when moving at high speed, and reducing yarn wear under the action of the pulley.
