During the rotation of the mounting wheel, the mounting wheel drives the sliding rod 1 and the sliding rod 2 to rotate synchronously through the sliding rail. During the rotation of the sliding rod 2, the end of the sliding rod 2 will slide along the inner wall of the elliptical track, and will be affected by the elliptical shape of the elliptical track. When it reaches the elliptical track, the end of the sliding rod 2 will slide along the inner wall of the elliptical track.

The liquid inside the slide groove 1 will push the hydraulic rod 1 to slide outward along the inner wall of the slide groove 1. While the two hydraulic rods 1 drive the corresponding rollers to move outward, the outer wall of the roller will contact the outer wall of the sample line.

In order to solve the problem that the staff needs to repeatedly load materials after a single test, a driving mechanism 2 and a control mechanism 3 are arranged inside the equipment. Before use, the base 1 is installed in the desired position, and the sample line 16 to be tested is tied to the outer wall of one of the slide rods 25 through the swing rod 13, and finally the power of the motor 29 is turned on. During this process, the motor 29 drives the multiple sliding rails 23, the sliding rod 1 25 and the extrusion block 2 26 to rotate through the mounting wheel 22, and the rotating extrusion block 2 26 will contact the side wall of the sliding rod 3 32, forcing the sliding rod 3 32 to slide outward along the inner wall of the sliding rail 31.

[0039] For example 2, please refer to Figure 5 - Fig.10 The present invention is a yarn wear detection device. On the basis of the first embodiment, the grinding mechanism 4 includes a CNC motor 41 fixedly connected to the top of the base 1, and the output shaft of the CNC motor 41 is fixedly connected to the grinding disc 42. The transmission rod 34 is connected to the side wall of the spring 15 through one end of the hydraulic telescopic rod 2 33. When the extrusion block 26 moves up and gets rid of the restriction of the sliding rod 32, the spring on the outer wall of the hydraulic telescopic rod 2 33 and the spring 15 will force the swing rod 13 to reset. Through the application of the above components, the sample line 16 finally presents as shown in the following figure. Figure 1In the state shown, the rotating mounting wheel 22 will drive the sample line 16 to approach the grinding mechanism 4 to perform a wear resistance test on the sample line 16, and the "Z"-shaped distribution method can realize automatic wiring of the equipment, avoiding frequent line changes by staff, which will affect the test results of the equipment.

[0040] The grinding mechanism 4 also includes a mounting block 43 slidably connected to the side wall of the sliding rod 25, a sliding groove 44 is provided on the inner wall of the mounting block 43, and a hydraulic rod 45 is slidably connected to the inner wall of the sliding groove 44. Utilizing the characteristic that the sample line 16 presents a "Z"-shaped distribution, a grinding mechanism 4 and a driving mechanism 2 are arranged inside the device. During the rotation of the mounting wheel 22, the mounting wheel 22 drives the sliding rod 25 and the sliding rod 27 to rotate synchronously through the sliding rail 23. During the rotation of the sliding rod 27, the end of the sliding rod 27 will slide along the inner wall of the elliptical track 28, and is limited by the elliptical shape of the elliptical track 28. When it reaches Figure 5 When the position of the middle C is reached, the sliding rod 25 is forced to move outward along the inner wall of the sliding rail 23 due to the influence of the elliptical position of the elliptical track 28, presenting Figure 6 The mounting wheel 22 continues to rotate, and the sliding rod 27 forces the sliding rod 1 25 to move along the sliding rail 23 toward the center of the mounting wheel 22, so that the extrusion block 1 24 and the extrusion block 2 26 form a clamping state, showing as shown in FIG. Figure 7 In the present invention, by using the above-mentioned components, after the "Z"-shaped sample line 16 is worn and broken by the grinding disk 42 at one end, the clamped sample line 16 will not be loosened due to the breakage of the front-end line, thereby affecting the detection efficiency of the equipment.

[0041] The grinding mechanism 4 also includes a roller 46 rotatably connected to the side wall of the hydraulic rod 45, a correction wheel 47 is rotatably connected to the top of the swing rod 13, and an outer support assembly 5 is slidably connected to the inner wall of the mounting block 43.

[0042] The outer support assembly 5 also includes two slide grooves 2 51 provided on the inner wall of the mounting block 43, the side walls of the two slide grooves 2 51 are connected to the side walls of the sliding groove 1 44, and the end of the hydraulic telescopic rod 2 33 away from the sliding rod 3 32 is fixedly connected to the side wall of the slide rail 31. By utilizing the force of the extrusion block 2 26 and the extrusion block 1 24 approaching each other, a grinding mechanism 4 and an outer support assembly 5 are arranged inside the equipment. When the extrusion block 26 and the extrusion block 1 24 approach each other, the extrusion block 26 forces the hydraulic sliding plate 52 to move along the inner wall of the slide groove 2 51 through the fixed rod 53. The two hydraulic rods 45 move inward, so that the liquid in the slide groove 2 51 enters the slide groove 1 44. The liquid in the slide groove 44 will push the hydraulic rod 45 to slide outward along the inner wall of the slide groove 44. At the same time, the two hydraulic rods 45 drive the corresponding rollers 46 to move outward, and the outer wall of the roller 46 will contact the outer wall of the sample line 16. Through the application of the above components, the "Z"-shaped corner area of ​​the sample line 16 is expanded, so that the sample line 16 is prevented from being subjected to excessive pressure during grinding, resulting in fracture at the corner position due to extrusion, which affects the detection accuracy of the equipment.

[0043] The outer support assembly 5 also includes a hydraulic sliding plate 52 slidably connected to the inner wall of the second slide groove 51, and a fixed rod 53 is fixedly connected to the side wall of the hydraulic sliding plate 52. The end of the sliding rod 27 away from the sliding rod 1 25 is slidably connected to the inner wall of the elliptical track 28. Utilizing the rotation characteristics of the above-mentioned mounting wheel 22, after the sample line 16 is polished, the sample line 16 will break, and at this time, the sliding rod 27 will enter the protruding position of the elliptical track 28 again, and the outward-opened extrusion block 26 and the extrusion block 1 24 will release the clamped line, so that the sample line 16 that has completed the inspection will fall downward, thereby realizing autonomous removal of the thread head and extending the inspection time.

[0044] The outer support assembly 5 also includes a spring 54 fixedly connected to the side wall of the hydraulic sliding plate 52, the other end of the spring 54 is fixedly connected to the inner wall of the slide groove 51, the end of the fixed rod 53 away from the hydraulic sliding plate 52 is fixedly connected to the side wall of the extrusion block 26, and the other end of the hydraulic telescopic rod 14 is rotatably connected to the side wall of the swing rod 13. The hydraulic rod 1 45 is used to drive the roller 46 to move outward. Since the sample line 16 is clamped by the extrusion block 26 and the extrusion block 1 24, the roller 46 extending outward will force the sample line 16 to be in a taut state. Through the application of the above-mentioned components, when the sample line 16 contacts the grinding disk 42, it is prevented from being in a loose state, resulting in a large measurement accuracy error.

[0045] The method for using the yarn detection device comprises the following steps:

[0046] S1: Install the sample;

[0047] S2: connection line;

[0048] S3: Turn on the power.

[0049] A specific application of this embodiment is: before use, the base 1 is installed at the desired position, and the sample line 16 to be tested is tied to the outer wall of one of the sliding rods 25 through the swing rod 13, and finally the power of the motor 29 is turned on. In this process, the motor 29 drives the multiple sliding rails 23, the sliding rod 25 and the extrusion block 26 to rotate through the mounting wheel 22, and the rotating extrusion block 26 will contact the side wall of the sliding rod 32, forcing the sliding rod 32 to slide outward along the inner wall of the sliding rail 31. At this time, the hydraulic telescopic rod 23 is compressed, and the hydraulic telescopic rod 23 is pressed. The liquid inside the second 33 is transmitted to the inside of the hydraulic telescopic rod 14 through the transmission rod 34, forcing the hydraulic telescopic rod 14 to extend, and the hydraulic telescopic rod 14 drives the swing rod 13 to swing with the central axis rod 12 as the center of gravity, forcing the swing rod 13 to drive the gap of the sliding rail 23 of the sample line 16 to swing to the other end; in addition, when the extrusion block 26 moves up and gets rid of the restriction of the sliding rod 32, the spring on the outer wall of the hydraulic telescopic rod 23 and the spring 15 will force the swing rod 13 to reset. Through the application of the above components, the sample line 16 finally presents as shown in the following figure. Figure 1 In the state shown, the rotating mounting wheel 22 will drive the sample line 16 to approach the grinding mechanism 4 to perform a wear resistance test on the sample line 16, and the "Z"-shaped distribution method can realize automatic wiring of the equipment, avoiding frequent line changes by staff, which will affect the test results of the equipment.

[0050] Taking advantage of the "Z"-shaped distribution of the sample line 16, a grinding mechanism 4 and a driving mechanism 2 are provided inside the device. During the rotation of the mounting wheel 22, the mounting wheel 22 drives the sliding rod 1 25 and the sliding rod 27 to rotate synchronously through the sliding rail 23. During the rotation of the sliding rod 27, the end of the sliding rod 27 will slide along the inner wall of the elliptical track 28, and is limited by the elliptical shape of the elliptical track 28. When reaching Figure 5 When the position of the middle C is reached, the sliding rod 25 is forced to move outward along the inner wall of the sliding rail 23 due to the influence of the elliptical position of the elliptical track 28, presenting Figure 6 The mounting wheel 22 continues to rotate, and the sliding rod 27 forces the sliding rod 1 25 to move along the sliding rail 23 toward the center of the mounting wheel 22, so that the extrusion block 1 24 and the extrusion block 2 26 form a clamping state, showing as shown in FIG. Figure 7 In the present invention, by using the above-mentioned components, after the "Z"-shaped sample line 16 is worn and broken by the grinding disk 42 at one end, the clamped sample line 16 will not be loosened due to the breakage of the front-end line, thereby affecting the detection efficiency of the equipment.

[0051] By utilizing the force of the extrusion block 26 and the extrusion block 1 24 approaching each other, a grinding mechanism 4 and an external support assembly 5 are provided inside the equipment. When the extrusion block 26 and the extrusion block 1 24 approach each other, the extrusion block 26 forces the hydraulic sliding plate 52 to move inward along the inner wall of the slide groove 2 51 through the fixed rod 53, so that the liquid inside the slide groove 2 51 enters the inside of the slide groove 1 44. The liquid inside the slide groove 1 44 will push the hydraulic rod 1 45 to slide outward along the inner wall of the slide groove 1 44. While the two hydraulic rods 1 45 drive the corresponding rollers 46 to move outward, the outer wall of the roller 46 will contact the outer wall of the sample line 16. Through the application of the above-mentioned components, the "Z"-shaped corner area of ​​the sample line 16 is expanded to avoid the sample line 16 being subjected to excessive pressure during grinding, resulting in the corner position being broken due to extrusion, thereby affecting the detection accuracy of the equipment.

[0052] By utilizing the rotating characteristic of the mounting wheel 22, after the sample line 16 is polished, the sample line 16 will break, and at this time, the sliding rod 27 will enter the protruding position of the elliptical track 28 again, and the extrusion block 26 and the extrusion block 1 24 opened outward will loosen the clamped line, so that the sample line 16 that has completed the inspection will fall downward, thereby realizing the autonomous removal of the thread head and extending the inspection time; in addition, by utilizing the characteristic of the hydraulic rod 1 45 driving the roller 46 to move outward, since the sample line 16 is clamped by the extrusion block 26 and the extrusion block 1 24, the roller 46 extending outward will force the sample line 16 to be in a taut state. Through the application of the above-mentioned components, when the sample line 16 contacts the polishing disc 42, it is prevented from being in a loose state, resulting in a large measurement accuracy error.
