And the yarn on the yarn bobbin can be guided through the guiding ring 33. The position of the yarn can be restricted through the guiding ring 33, so that the position of the yarn is always at the groove on the fixed jaw clamping plate 31. Personnel can take out the yarn end on the yarn bobbin, pass the yarn end through the hole on the guiding ring 33 fixedly connected to the connecting plate 23 and place it between the lower friction pads 32 fixedly connected to the fixed jaw clamping plate 31, so that part of the yarn is at the groove on the fixed jaw clamping plate 31. By making the two fixed jaw clamping plates 31 approach each other, the yarn is clamped by them. The lower friction pads 32 fixedly connected to the two fixed jaw clamping plates 31 are in contact with each other;

[0040] The threaded hole opened on the moving plate 9 is threadedly connected to the inner screw rod 11. One end of the inner screw rod 11 is rotatably connected to the fixed frame 2 through a shaft. The other end of the inner screw rod 11 is fixedly connected to the worm gear 12. The worm gear 12 is rotatably connected to the fixed frame 2 through a shaft.

The worm 13 is in meshing transmission with the worm gear 12, driving the worm gear 12 to rotate, so that the inner screw rod 11 rotates along the threaded hole opened on the moving plate 9;

[0041] A tension sensor body 7 is fixedly installed on the moving jaw body 6. The other end of the tension sensor body 7 is fixedly installed on the moving mechanism 8. A moving plate 9 is fixedly connected to the moving mechanism 8. The moving plate 9 is in the shape of a "convex" plate. The protruding ends on both sides of the moving plate 9 are stuck in the square groove 10 opened in the fixed frame 2, and the moving plate 9 can slide along the square groove 10, so that the moving plate 9 slides along the square groove 10 opened in the fixed frame 2, making the moving mechanism 8, the tension sensor body 7 and the moving jaw body 6 move downward. When the moving jaw body 6 is in the descending state, the moving jaw clamping plate 25 and the upper friction pad 26 fixedly connected to the moving jaw clamping plate 25 are far away from the other moving jaw clamping plate 25 and the upper friction pad 26 fixedly connected to the moving jaw clamping plate 25, which does not interfere with the later operation;

[0042] The threaded holes formed in the upper slider 24 are threadedly connected to the moving jaw screw 21. The thread directions at both ends of the moving jaw screw 21 are opposite, and both ends of the moving jaw screw 21 are threadedly connected to the upper slider 24. The moving jaw screw 21 is rotationally connected to the moving jaw body 6 through a shaft. The other end of the shaft of the moving jaw screw 21 is fixedly connected to the transmission shaft of the moving jaw motor 20. The moving jaw motor 20 is fixedly installed on the moving jaw body 6. When the pressure generated by the moving jaw body 6 on the upper surface of the fixed jaw body 5 exceeds a predetermined value, the driving motor 14 is stopped, and the moving jaw motor 20 is started to drive the moving jaw screw 21 to rotate, so that the moving jaw screw 21 rotates along the threaded holes formed in the upper slider 24;

[0043] The upper chute 22 is formed in the moving jaw body 6. The upper chute 22 is in an "L"-shaped groove structure. The upper slider 24 is arranged in the upper chute 22. The upper slider 24 is in an "L"-shaped plate structure. The upper slider 24 can slide along the upper chute 22. By sliding the upper slider 24 along the upper chute 22, the moving jaw clamping plate 25 and the upper friction pad 26 move along the upper chute 22, so that the convex blocks at one ends of the moving jaw clamping plate 25 and the upper friction pad 26 are inserted into the grooves formed in the fixed jaw clamping plate 31, and the yarn in the grooves formed in the fixed jaw clamping plate 31 is clamped by the moving jaw clamping plate 25 and the upper friction pad 26;

[0044] The threaded hole formed in the lower slider 30 is threadedly connected to the fixed jaw screw 28. The thread directions at both ends of the fixed jaw screw 28 are opposite, and the fixed jaw screw 28 is threadedly connected to the lower sliders 30 at both ends. One end of the fixed jaw screw 28 is rotatably connected to the fixed jaw body 5 through a rotating shaft, and the fixed jaw screw 28 is fixedly connected to the driving end of the fixed jaw motor 27 through the rotating shaft. The fixed jaw motor 27 is fixedly installed on the fixed jaw body 5. The following realizes the timing operation through the control device on the device. After reaching the predetermined time, the fixed jaw motor 27 starts to rotate the fixed jaw screw 28, so that the fixed jaw screw 28 rotates along the threaded hole formed in the lower slider 30, causing the lower friction pad 32 and the fixed jaw clamping plate 31 to slide along the lower sliding groove 29, and no longer clamping the yarn. At the same time, the driving motor 14 starts, driving the moving plate 9, the moving mechanism 8, the tension sensor body 7 and the moving jaw body 6 to move upward. After reaching the predetermined time, the fixed jaw motor 27 is started to make the two fixed jaw clamping plates 31 approach each other, so that the lower friction pad 32 clamps the yarn. At this time, the moving jaw body 6 still moves upward, generating a tension on the yarn, which is monitored by the tension sensor body 7. Through the above, the detection of the yarn strength is realized, and after reaching the predetermined time, the moving jaw body 6 is controlled to descend. Through the above repeated operation, the automatic detection of the yarn is realized. Personnel only need to install the yarn on the device and clamp the yarn end through the fixed jaw body 5, and then the device can perform automatic detection, without the need for personnel to repeatedly operate online, which is convenient for personnel to actually use.

[0045] Embodiment 3

[0046] On the basis of Embodiment 2, in order to improve the use effect of the device, a fixed jaw body 5 is provided. A lower sliding groove 29 is formed in the fixed jaw body 5.

The moving jaw clamping plate 25 has a "concave"-shaped plate structure. An upper friction pad 26 is fixedly connected to the moving jaw clamping plate 25. The upper friction pad 26 has a "concave"-shaped plate structure.

The mounting block 4 is fixedly installed on the fixed frame 2. An accordion-shaped protective cover 3 is fixedly connected to the mounting block 4. The other end of the accordion-shaped protective cover 3 is fixedly connected to the moving plate 9. By means of the accordion-shaped protective cover 3, the broken yarn can be prevented from floating onto the inner screw rod 11 and thus affecting the transmission of the inner screw rod 11.

[0048] Working principle: In actual use, the moving jaw clamping plate 25 and the fixed jaw clamping plate 31 provided can be clamped. In cooperation with the yarn bobbin mounting rack 18 on the device, the detection work of an entire yarn bobbin can be carried out. After one detection is completed, the moving jaw clamping plate 25 can move downward to clamp the yarn end on the fixed jaw clamping plate 31. The fixed jaw clamping plate 31 can move away from the yarn end. The moving jaw body 6 moves upward. Then, the fixed jaw clamping plate 31 clamps the yarn to carry out the yarn strength detection. After the yarn breaks, the moving jaw body 6 moves downward, and the reciprocating operation can be carried out to realize the continuous strength detection work of the yarn, without the need for personnel to repeatedly perform the online operation, reducing the work burden of personnel and facilitating the use of personnel.
