Embodiment 1

[0014] Such as figure 1 As shown, a yarn breakage shutdown system includes a tension adjustment box body 1. Outside the tension adjustment box body 1, the tension adjustment box includes a wire inlet 2, a wire inlet 2 3, a tension 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 adjustment box body 1 by a nut 8, and one end of the adjustment bolt 7 is located outside the tension adjustment box; the box body also has a switch 9 for controlling the opening and closing of the loom, and one end of the switch 9 is connected to the tension adjustment 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 direction of ...

Embodiment 2

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

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 break stop system. Background technique [0002] In the weaving process, since the weft yarn has to pass through multiple lead holes or devices to reach the weaving machine, the weft yarn will rub against the contacting device during this process, which greatly increases the probability of yarn breakage. If the yarn cannot be stopped in time for wiring after the yarn is broken, a large amount of yarn will be wasted. How to stop the yarn in time after the yarn is broken is an urgent problem in the textile field. In the prior art, sensors are generally used to sense the broken yarn and then alarm, but the sensor is affected by the material. Due to the limitations of conditions and conditions, the sensitivity will not be high, resulting in the inability to generate induction in time, resulting in the inability to issue an alarm in time. Contents of the invention [0003] The technical problem to be solved by the present ...
