[0043] When in use, the clamping component 2, the continuous pulling test component 3, the tension testing mechanism, the winding component 4 and the pay-off unit provide an online continuous damage detection device before production for the silk thread used in high-tech fields such as medical treatment. By continuously performing pulling tests on the silk thread on the path of the continuous pulling test component 3, the weaknesses, breaks or potential quality problems of the silk thread can be effectively identified, effectively ensuring the stability and reliability of the product quality, so that the use quality and yield rate of the entire set of silk threads after winding are guaranteed.

[0044] The clamping assembly 2 comprises a first gear seat 21 and a second gear seat 22 embedded and fixed on the top of the wire conveying platform 1, and the top ends of the first gear seat 21 and the second gear seat 22 are respectively rotatably mounted with a symmetrically arranged first cam 23 and a second cam 24 through bearings, and the bottoms of the first cam 23 and the second cam 24 are connected with meshing gears 25;

[0045] A first synchronous wheel 26 mounted on the shaft head of the gear 25 is provided at the bottom of one end of the first gear seat 21. The first synchronous wheel 26 in the first gear seat 21 is connected to the first synchronous wheel 26 in the second gear seat 22 through a synchronous belt. A second synchronous wheel 27 is installed at the bottom of the first synchronous wheel 26.

[0046] When in use, the fourth synchronous wheel 35 on the driving shaft of the servo motor 34 drives the second synchronous wheel 27 and the seventh synchronous wheel 61 to rotate, and the second synchronous wheel 27 drives the first synchronous wheel 26 above to rotate. At the same time, the first synchronous wheel 26 of the second gear seat 22 rotates at the same time, so that the gear 25 and the second cam 24 above the first synchronous wheel 26 rotate. Based on the engagement between the gears 25, the first cam 23 will rotate synchronously with the second cam 24, and the first cam 23 and the second cam 24 will clamp and fix the wire passing through the clamping component 2 every time they rotate one circle, so that the wire is suspended and retained in the continuous pulling test component 3.

[0048] The fourth synchronous wheel 35 is connected to the second synchronous wheel 27 via a synchronous belt.

[0049] When in use, the driving force of the servo motor 34 drives the turntable 37 at the top to rotate synchronously with the fourth synchronous wheel 35 and the fifth synchronous wheel 36. Based on the rotation, the turntable 37 drives the tension testing mechanism to rotate along the circumference of the turntable 37. The tension testing mechanism drives the wire drawing wheel 33 on the slider 32 to slide back and forth horizontally on the slide rail 31. When the clamping assembly 2 performs a set of clamping movements on the silk thread, the wire drawing wheel 33 slides the farthest distance on the slide rail 31, and the wire drawing wheel 33 completes a set of pulling movements during the wire clamping process. During the pulling period, the tension of the cover is elastically buffered by the tension spring 86, and the tension spring 86 can be replaced and adjusted according to the actual strength requirements of the test.

[0052] When in use, the tension sensor 82 measures and records the force value during pulling in real time, and the processor compares it based on a preset threshold value. If the force value suddenly decreases, it indicates that the silk thread is broken; or exceeds the normal range, indicating that the silk thread is insufficient in strength, the alarm of the control host 9 is triggered, and the stepper motor 43 and the servo motor 34 stop running. At the same time, the alarm signal is transmitted to the online detection system of the silk thread processing site by wireless data transmission.

[0060] A ninth synchronous wheel 76 is installed at the bottom of the reciprocating screw rod 72 through the seat plate 71 . The ninth synchronous wheel 76 is connected to the third synchronous wheel 44 through a synchronous belt.

[0061] When in use, while the stepper motor 43 is working, the third synchronous wheel 44 on the stepper motor 43 drives the ninth synchronous wheel 76 to rotate, causing the reciprocating screw rod 72 to rotate, and based on the rotation, the lifting plate 74 drives the wire wheel 75 to move back and forth up and down on the reciprocating screw rod 72, so that the wire can be wound more evenly during the winding process of the winding sleeve.

[0066] Step 4: The driving force of the servo motor 34 drives the turntable 37 at the top to rotate synchronously with the fourth synchronous wheel 35 and the fifth synchronous wheel 36. Based on the rotation, the turntable 37 drives the tension test mechanism to rotate along the circumference of the turntable 37. The tension test mechanism drives the wire drawing wheel 33 on the slider 32 to slide back and forth horizontally on the slide rail 31. When the clamping assembly 2 performs a set of clamping movements on the wire, the wire drawing wheel 33 slides the farthest distance on the slide rail 31, and the wire drawing wheel 33 completes a set of pulling movements during the wire clamping process. During the pulling period, the tension of the cover is elastically buffered by the tension spring 86.
