[0031] Specifically, during the wear resistance test, the rotating first reciprocating screw 7 will drive the short shaft 27 to rotate through the chain drive 28, and the short shaft 27 will drive the active gear 29 to rotate, and the active gear 29 will drive the passive gear 38 to rotate, and the passive gear 38 will drive the second reciprocating screw 30 to rotate, and the second reciprocating screw 30 will drive the first push plate 31 to slide back and forth, and the first push plate 31 will intermittently press the first top block 32. When the first top block 32 is pressed, it will drive the left support 3 to slide in the direction away from the right support 2 and compress the transverse spring 26. The left support 3 will laterally stretch the needle textile, so that the needle textile simulates being tightened and worn by foreign objects at the same time, making the detection process more in line with reality and improving the accuracy of the wear resistance test of the needle textile. When the first top block 32 is not pressed by the first push plate 31, the transverse spring 26 will elastically reset, thereby driving the left support 3 to slide in the opposite direction and reset.

[0032] The base 1 is provided with a longitudinal groove 23 which is perpendicular to and connected with the transverse groove 22, a longitudinal spring 25 is installed between the slide 24 and the inner wall of the longitudinal groove 23, the transverse groove 22 and the longitudinal groove 23 are combined into an L-shaped groove, the slide 24 can slide along the longitudinal groove 23 and along the transverse groove 22, but cannot slide in two directions at the same time, wherein the base 1 is rotatably connected with a third reciprocating screw 33 which is perpendicular to the second reciprocating screw 30, the third reciprocating screw 33 is provided with a second push plate 34 which is slidably connected with the base 1, the third reciprocating screw 33 is used to drive the second push plate 34 to slide back and forth, the left support 3 is fixedly connected with a second top block 35 which is opposite to the second push plate 34, and the base 1 is provided with a second push plate 35 which is opposite to the second push plate 34. A rotating rod 36 arranged parallel to the second reciprocating screw 30 is rotatably installed, and a driven gear 37 meshing with the driving gear 29 is fixedly installed on the rotating rod 36. The rotating rod 36 is connected to the third reciprocating screw 33 through two mutually meshing bevel gears 39. The gear teeth on the driving gear 29 are only half, and when the driving gear 29 is meshed with the driven gear 38, the second reciprocating screw 30 will drive the first push plate 31 to slide back and forth once, and then the driving gear 29 will separate from the driven gear 38 and mesh with the driven gear 37, and the third reciprocating screw 33 will drive the second push plate 34 to slide back and forth once, and the driving gear 29 cannot be meshed with the driven gear 37 and the driven gear 38 at the same time.

[0033] Since there are only half of the gear teeth on the active gear 29, when the gear teeth on the active gear 29 do not mesh with the passive gear 38, they will mesh with the driven gear 37 and drive the rotating rod 36 to rotate. The rotating rod 36 will drive the third reciprocating screw 33 to rotate through two mutually meshing bevel gears 39. The third reciprocating screw 33 will drive the second push plate 34 to slide back and forth once. The second push plate 34 will first push the second top block 35. The second top block 35 will drive the left support 3 to slide in a direction perpendicular to the transverse groove 22 and compress the longitudinal spring 25. At the same time, it will drive one end of the needle textile to slide synchronously. The needle textile will be subjected to an inclined pulling force and wrinkles will be generated on the surface, thereby simulating the needle textile to be subjected to an inclined pulling force and wrinkles when in use, and at the same time being rubbed by the friction head 6, so that the wear resistance detection of the needle textile is more accurate. When the second push plate 34 is reset in the opposite direction, the longitudinal spring 25 will drive the left support 3 to slide in the opposite direction and reset, and the needle textile will be realigned.

[0034] Embodiment 4: Reference Figure 1-Figure 2 as well as Figure 5-Figure 7 , which is basically the same as the third embodiment, and further, a specific implementation scheme is specifically added to make the sliding path of the friction head 6 more random.

[0035] A horizontal plate 11 is fixedly connected to the base 1, and a curved groove 12 is provided on the horizontal plate 11. The curved groove 12 is provided with at least one straight path, one curved path and one oblique path. The order and number of the various paths can be adjusted as needed, but they must be connected to form a complete path. A vertical rod 10 is slidably installed at the lower end of the reciprocating slider 5, and the lower end of the vertical rod 10 is slidably sleeved in the curved groove 12, and the friction head 6 is installed on the vertical rod 10.

[0036] When the reciprocating slider 5 slides back and forth, the reciprocating slider 5 will drive the vertical rod 10 to slide back and forth in the curved groove 12. Since there is at least one section of straight line, curved and oblique line in the curved groove 12, the vertical rod 10 will not only slide back and forth horizontally, but also make at least one section of straight line, curved and oblique line sliding, which will drive the friction head 6 to make various friction routes, so that the friction path of the friction head 6 is more in line with the randomness in reality, and the wear resistance detection accuracy of needle textiles is improved. At the same time, with the reciprocating left support 3, the friction path of the friction head 6 will be more random, which is more in line with the actual complex use environment.

[0037] Embodiment five: Reference Figure 5-Figure 7 , which is basically the same as the fourth embodiment, and further, a specific implementation scheme for adjusting the friction head 6 is specifically added.

[0038] A turntable 13 is rotatably connected to the vertical rod 10, and a plurality of friction heads 6 are provided, the number of friction heads 6 being 3 to 10 groups, and the preferred number in this application being 6 groups, and all of them are installed on the circumferential outer wall of the turntable 13, and an adjustment portion for driving the turntable 13 to rotate is provided on the vertical rod 10; the adjustment portion includes a handle 20 rotatably installed on the outer wall of the vertical rod 10, and the handle 20 is connected to the turntable 13 through a first worm gear assembly 18, and the first worm gear assembly 18 is mainly composed of two mutually meshing worms and worm wheels.

[0039] Specifically, when it is necessary to replace the friction head 6 with a different shape, such as conical, cylindrical, blade-shaped or spiral, turn the handle 20, and the handle 20 will drive the turntable 13 to rotate through the first worm gear assembly 18. When the other set of friction heads 6 is set downward, stop turning the handle 20 to complete the replacement of the friction head 6. It is more convenient to use and is convenient for needle textiles to perform wear resistance testing of different friction heads 6.

[0040] The friction head 6 is rotatably mounted on the outer wall of the turntable 13, and a disc gear 15 is fixedly mounted on the outer wall of the friction head 6. A linkage portion for driving the disc gear 15 to rotate is provided on the vertical rod 10, and the linkage portion includes a transmission shaft 16 rotatably connected to the vertical rod 10, and a ring gear 14 meshing with the disc gear 15 is rotatably mounted on the vertical rod 10. The transmission shaft 16 is connected to the ring gear 14 through a second worm gear assembly 21, and a spur gear 17 is fixedly mounted on the transmission shaft 16. A rack 19 that cooperates with the spur gear 17 is fixedly mounted on the lower end of the horizontal plate 11.

[0041] Specifically, when the reciprocating slider 5 drives the vertical rod 10 to slide back and forth, the vertical rod 10 will also drive the spur gear 17 to slide back and forth. When the spur gear 17 sweeps along the rack 19, the spur gear 17 will drive the transmission shaft 16 to rotate, and the transmission shaft 16 will drive the ring gear 14 to rotate through the second worm gear assembly 21. The ring gear 14 will drive the disc gear 15 to rotate, and the disc gear 15 will drive the friction head 6 to rotate, so that the friction head 6 rotates to perform wear resistance testing on the needle textiles, making the wear resistance testing more in line with the complex use environment in reality and improving the accuracy of the wear resistance testing.

[0042] In practice, in order to make the sliding path of the friction head 6 more random, the rack 19 can be installed at the turning of two different paths, such as the turning of a straight path and a curved path, so that the friction head 6 will slide and rotate in a more random path, making the wear resistance detection more accurate.

[0043] A wear resistance testing method for knitted textiles, the operating steps are as follows: Step 1: Fix the two ends of the knitted textile and lay it flat; Step 2: Make the friction head 6 slide back and forth on the surface of the needle textile; Step 3: Make the reciprocating friction head 6 reciprocate along a curved path, a straight path and an oblique path; Step 4: Make the knitted textile indirectly stretched in a straight line direction and in a diagonal direction during the test; Step 5: Observe in real time whether the knitted textile is damaged. If the knitted textile is damaged in a short time, it is judged that the wear resistance is poor. Otherwise, it is judged that the wear resistance is good.

[0044] The present invention is a wear-resistant testing device for needle textiles. When in use, the needle textiles are fixed between the right support 2 and the left support 3 by the clamp 4. At this time, the friction head 6 arranged downward will be placed on the needle textiles. At this time, the driving motor 9 is started, and the driving motor 9 will drive the first reciprocating screw 7 to rotate, and the first reciprocating screw 7 will drive the reciprocating slider 5 to slide back and forth on the crossbeam 8, and the reciprocating slider 5 will drive the friction head 6 to slide back and forth on the needle textiles to complete the wear resistance test of the needle textiles. During this period, the first reciprocating screw 7 will drive the short shaft 27 to rotate through the chain drive 28, and the short shaft 27 will drive the driving gear 29 to rotate, and the driving gear 29 will drive the passive gear 3 When the first push plate 31 is pressed, the left support 3 will be driven to slide in the direction away from the right support 2 and compress the transverse spring 26. The left support 3 will stretch the needle textile laterally, so that the needle textile is simulated to be tightened and worn by foreign objects at the same time, making the detection process more realistic and improving the accuracy of the wear resistance detection of the needle textile. When the first push block 32 is not pressed by the first push plate 31, the transverse spring 26 will be elastically reset, thereby driving the left support 3 to slide in the opposite direction and reset.

[0045] Since there are only half of the gear teeth on the active gear 29, when the gear teeth on the active gear 29 do not mesh with the passive gear 38, they will mesh with the driven gear 37 and drive the rotating rod 36 to rotate. The rotating rod 36 will drive the third reciprocating screw 33 to rotate through two mutually meshing bevel gears 39. The third reciprocating screw 33 will drive the second push plate 34 to slide back and forth once. The second push plate 34 will first push the second top block 35. The second top block 35 will drive the left support 3 to slide in a direction perpendicular to the transverse groove 22 and compress the longitudinal spring 25. At the same time, it will drive one end of the needle textile to slide synchronously. The needle textile will be subjected to an inclined pulling force and wrinkles will be generated on the surface, thereby simulating the needle textile to be subjected to an inclined pulling force and wrinkles when in use, and at the same time being rubbed by the friction head 6, so that the wear resistance detection of the needle textile is more accurate. When the second push plate 34 is reset in the opposite direction, the longitudinal spring 25 will drive the left support 3 to slide in the opposite direction and reset, and the needle textile will be realigned.

[0046] When the reciprocating slider 5 slides back and forth, the reciprocating slider 5 will drive the vertical rod 10 to slide back and forth in the curved groove 12. Since there is at least one section of straight line, curved and oblique line in the curved groove 12, the vertical rod 10 will not only slide back and forth horizontally, but also make at least one section of straight line, curved and oblique line sliding, which will drive the friction head 6 to make various friction routes, so that the friction path of the friction head 6 is more in line with the randomness in reality, and the wear resistance detection accuracy of needle textiles is improved. At the same time, with the reciprocating left support 3, the friction path of the friction head 6 will be more random, which is more in line with the actual complex use environment.
