Description

Technical Field

[0001] The utility model relates to the technical field of weaving thread feeding, in particular to an auxiliary thread feeding device for weaving. Background Art

[0002] Cloth is a general term for all kinds of fabrics. It is a textile made from raw materials such as plant fibers, animal fibers or chemical fibers through weaving or knitting processes. In the weaving process of cloth, the silk thread needs to be fed into the weaving machine through a wire feeding device, and then the weaving machine weaves it into cloth.

[0003] During the wire feeding process, the silk threads are continuously pulled out from the ball of thread. Once the wire breaks or the ball of thread is completely pulled out, the silk threads will not be able to continue to be fed, but the downstream braiding machine is still running, resulting in braiding errors. The operator needs to find out and then re-connect the silk threads. It is also easy to find the terminal head when wiring, which seriously affects the braiding efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide an auxiliary wire feeding device for weaving. When the wire breaks or the silk thread is drawn out, the pressure on the pressure sensor suddenly decreases, thereby generating an electrical signal pulse and transmitting it to the PLC controller. The PLC controller then activates the alarm to serve as a prompt so that the operator can connect the wires or replace the wire reel in time. At the same time, the electric rod is also started to push the clamping block upward to clamp the silk thread wound on the second guide roller, so that the operator can find the thread end more conveniently and continue the silk thread, which greatly improves the reaction force of the device and improves the stability and transmission efficiency of the wire feeding.
