Description

Technical Field

[0001] The invention relates to the technical field of knitting traction, in particular to a double-head traction mechanism for a flat knitting machine. Background Art

[0002] The double-head traction mechanism of the knitting machine is used to control the direction of the knitting thread and transport it to the knitting machine. This mechanism is usually equipped with two independent traction systems, which work together to ensure that the knitting thread passes through the needle bed of the knitting machine smoothly and accurately, thereby forming the desired knitting pattern.

[0003] When the existing double-head traction mechanism of a knitting machine is in use, it is difficult to adjust the contact force according to the change in the diameter of the knitting thread, which reduces the adaptability and flexibility of the equipment. At the same time, it is difficult to buffer the unevenness encountered by the knitting thread during the transportation process, resulting in a relatively unstable movement of the knitting thread, which increases the damage caused by vibration or impact; before adjusting the contact force according to the change in the diameter of the knitting thread, the existing technology is difficult to detect the diameter of the knitting thread, which may lead to a large error in the adjustment of the contact force, and may cause the problem of thread breakage caused by uneven tension, increasing the downtime;

[0004] In addition: it is difficult to detect the use of knitting thread with existing technology. When some equipment uses cameras for detection, it is difficult to keep the camera in the most optimized working state, resulting in unclear images taken by the camera.

[0005] Finally: In the prior art, it is difficult to pre-treat the winding roller before use, which reduces the service life of the winding roller and the knitting wire, and it is difficult to ensure that the knitting wire is smoothly released from the winding roller; in the prior art, after the knitting wire is used up, the staff usually disassembles the winding roller, which is more troublesome and requires shutdown processing. It is also difficult to realize the delivery of double sets of yarns, and its practicality is relatively simple. Summary of the invention
