Description

Technical Field

[0001] The utility model relates to the technical field of warp tension control of a wire weaving machine, in particular to a warp tension control component of a wire weaving machine. Background Art

[0002] In the textile industry, a wire weaving machine is one of the key devices. The warp tension is a very important parameter in the weaving process, which directly affects the quality, feel and appearance of the fabric. Appropriate warp tension can ensure the tightness and uniformity of the fabric, while too large or too small tension may cause quality problems in the fabric. In the process of transmitting the warp by the existing wire weaving machine, due to mechanical aging and other reasons, the warp is prone to breakage or tearing, etc., affecting the stability of the warp tension during transmission.

[0003] In view of the above related technologies, it is urgent to design and develop a warp tension control component for a wire weaving machine. By setting a tension sensor on the wire weaving machine, during the textile process of the wire weaving machine, it is convenient to detect the warp tension in real time. When the warp breaks or tears, etc., the tension sensor can detect the tension change in time and control whether the warp continues to be transmitted, reducing unnecessary economic losses.

[0049] The implementation principle of a tension control assembly of a net weaving machine in an embodiment of the present application is as follows:
