DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-4, a tension-adjustable yarn-break alarm device comprises a mounting frame 1, and a plurality of yarn-break alarm mechanisms 2 are symmetrically arranged on the side walls of the mounting frame 1, and the yarn-break alarm mechanism 2 comprises a yarn-break alarm device 5;

[0021] The yarn break alarm device 5 includes a tension bearing seat 53, which is installed on the side wall surface of the mounting frame 1. A rocker tension shaft 54 ​​is arranged at the inner ring of the bearing of the tension bearing seat 53, and an adjustable head 51 is arranged at the end of one side of the axis of the rocker tension shaft 54. The tension bearing seat 53 is located on the seat surface facing the adjustable head 51 and a tension adjustment seat 52 is installed.

[0022] Among them, a U-shaped bolt frame 6 is installed on the front side of the yarn break alarm device 5 on the side wall surface of the mounting frame 1, and a first wire guide assembly 3 and a second wire guide assembly 4 are respectively arranged above the yarn break alarm device 5. The first wire guide assembly 3 and the second wire guide assembly 4 are located on the same horizontal line. The first wire guide assembly 3 and the second wire guide assembly 4 are convenient for guiding the yarn and can also increase the tension of the yarn.

[0023] In addition, the first wire guide assembly 3 includes a wire holder 31, which is installed on the side wall surface of the mounting frame 1. A wire guide hook 32 is installed at the other end of the wire holder 31 away from the mounting frame 1, and the wire guide hook 32 facilitates guiding the yarn to the ceramic wheel 42.

[0024] Moreover, the second guide wire assembly 4 includes a conductor rod 41, which is installed on the side wall surface of the mounting frame 1. The other end of the conductor rod 41 away from the mounting frame 1 is rotatably provided with a ceramic wheel 42, and the ceramic material of the ceramic wheel 42 will not cause wear to the yarn.

[0025] Among them, the adjustable head 51 includes a rocker arm fixing seat 511, the rocker arm fixing seat 511 is arranged on the rocker arm tension shaft 54, a tension rocker arm 512 is fixedly connected to the seat body of the rocker arm fixing seat 511, and a tension ceramic wheel 513 is rotatably arranged on the other end of the tension rocker arm 512 away from the rocker arm fixing seat 511. The tension rocker arm 512 cooperates with the rocker arm fixing seat 511 to rotate by the rocker arm tension shaft 54, so that the distance between the tension ceramic wheel 513 and the upper ceramic wheel 42 can be adjusted, thereby playing a certain role in adjusting the tension.

[0026] Moreover, the tension swing rod 512 is arranged to move within the range inside the U-shaped bolt frame 6, and the U-shaped bolt frame 6 can well limit the swing range of the tension swing rod 512.

[0027] In this embodiment, when the twisting machine is used for twisting, a yarn break alarm mechanism 2 is set between the initial twisting and the secondary twisting, and the yarn passes through the wire guide hook 32, then is wound around and passes through the ceramic wheel 42, and finally passes through the tension ceramic wheel 513, and then is connected to the subsequent equipment.

[0028] At this time, the tension swing rod 512 is set at the bottom of the U-bolt frame 6, and then the rotation of the swing rod tension shaft 54 ​​can be adjusted through the tension adjustment seat 52, so that the tension swing rod 512 swings upward, and the yarn at this time will change due to the displacement tension of the tension ceramic wheel 513.

[0029] When the machine is started, the yarn has a certain tension and traction, so that the tension swing rod 512 is always located in the middle position of the U-bolt frame 6, and the tension swing rod 512 will not be placed on the bottom of the U-bolt frame 6, and the other end of the swing rod tension shaft 54 ​​away from the adjustable head 51 is connected to the position change alarm arranged in the mounting frame 1. This position change alarm is a prior art, and is an alarm that will sound an alarm when the shaft rotates to a specific position.

[0030] The alarm position of the position change alarm is the position when the tension swing rod 512 is placed on the bottom of the U-bolt frame 6. Therefore, when the twisting machine is working, once the yarn breaks, the yarn breaks and causes the yarn to detach from the tension ceramic wheel 513, so that the original tension swing rod 512 has a certain traction force on the tension ceramic wheel 513, so that the tension cover plate 512 swings and rises. At this time, after the yarn is detached, the tension swing rod 512 has no traction. Under the action of gravity, the tension swing rod 512 cooperates with the swing rod tension shaft 54 ​​to rotate, thereby swinging downward, so that the tension swing rod 512 is placed on the bottom of the U-bolt frame 6, and the swing rod tension shaft 54 ​​rotates to the alarm position at this time, so that the position change alarm alarms, and the operator can know it in time, and then immediately shut down the twisting machine and adjust the yarn.

[0031] In the utility model, a yarn break alarm mechanism 2 is provided, and the tension can be adjusted by adjusting the swing amplitude of the swing arm tension shaft 54. Moreover, after the yarn passes through the yarn break alarm mechanism 2, when the twisting machine is twisting, once the yarn breaks, the tension swing arm 512 has no traction, and under the action of gravity, the tension swing arm 512 cooperates with the swing arm tension shaft 54 ​​to rotate, thereby swinging downward, so that the tension swing arm 512 rests on the bottom of the U-bolt frame 6, and at this time the swing arm tension shaft 54 ​​rotates to the alarm position, so that the position change alarm connected to it sounds an alarm, so that the operator can know it in time, and then immediately shut down the twisting machine to adjust the yarn, thereby not delaying the twisting work.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
