Embodiment 1

[0014] like figure 1 As shown in the figure, a yarn breakage stop system includes a tension adjustment box body 1. Outside the tension adjustment box body 1, the tension adjustment box includes a thread inlet hole 1 2, a thread inlet hole 2 3, a tension adjustment box according to the yarn feeding direction in sequence Bracket 4 and outlet hole 5; in the tension adjustment box body 1, the tension bracket 4 is hinged with the tension adjustment box, the bottom end of the tension bracket 4 has a spring 6, and the other end of the spring 6 is fixedly connected with an adjustment bolt 7, and the adjustment bolt 7 The middle part is fixed on the tension adjusting box body 1 through the nut 8, and one end of the adjusting bolt 7 is located outside the tension adjusting box; The body 1 is hinged, and the other end of the switch 9 is located at the rear end of the bottom end of the tension bracket 4 along the wire feeding direction.

Embodiment 2

[0017] As an improvement of Embodiment 1, the tension support 4 has a rolling ring 10 at the contact point with the yarn, so that the sliding friction between the tension support 4 and the yarn is changed to rolling friction, and the wear of the yarn is reduced. , to a certain extent, the probability of yarn breakage is reduced.

Abstract

A shutdown system used when weft breaks comprises a tension adjusting box. The outer side of the tension adjusting box is sequentially provided with a first yarn inlet, a second yarn inlet, a tension support and a yarn outlet in the yarn feeding direction. The tension support and the tension adjusting box are hinged in the tension adjusting box, the bottom end of the tension support is provided with a spring, the other end of the spring is fixedly connected with an adjusting bolt, the middle portion of the adjusting bolt is fixed to the tension adjusting box through a nut, and one end of the adjusting bolt is located outside the tension adjusting box. A switch controlling start and shutdown of a loom is arranged in the tension adjusting box, one end of the switch is hinged to the tension adjusting box, and the other end of the switch is located at the rear end, in the yarn feeding direction, of the bottom of the tension support. According to the scheme, a shutdown switch and a weft tensioning device are integrated, the tension support quickly bounds under the drive of the spring when the weft suddenly breaks, the bottom of the tension support drives the switch while the tension support bounds so that the switch is disconnected with a circuit controlling the loom to operate, and the loom stops in time.

Description

technical field [0001] The invention relates to a yarn breakage stop system. Background technique [0002] During the weaving process, since the weft yarn has to pass through multiple lead holes or devices to reach the weaving machine, in this process, the weft yarn will rub against the device in contact, which greatly increases the probability of yarn breakage. If the yarn breakage cannot be stopped in time for wiring, a large amount of yarn will be wasted. How to stop the yarn break in time in the textile field is an urgent problem to be solved. In the prior art, a sensor is generally used to sense the yarn breakage and then alarm, but the sensor is affected by the material. Due to the limitation of conditions and conditions, the sensitivity will be low, resulting in the inability to generate induction in time, resulting in the inability to issue an alarm in time. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is: to overco...
