Description

[0014] 1. This bidirectional tensile testing device for blended yarns, by setting up traction and tension components within the device, allows the moving frame, sleeve, bevel gear assembly, turntable, winding rod, nut, second motor, and cross shaft within two sets of clamping components to cooperate with each other to clamp and straighten both sides of the blended yarn.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] See Figures 1-4 This utility model provides the following two technical solutions:

[0023] First embodiment: A biaxial tensile testing device for blended yarns, comprising a base 1, wherein the base 1 is connected to a measuring element for measuring the biaxial tensile strength of the blended yarn, the measuring element comprising:

[0024] The traction component 2, mounted on the base 1, is used for straightening blended yarns. The traction component 2 includes a bidirectional screw 22 rotatably connected to the right side of the base 1 along the Y-axis. A first slide rod 23 is fixedly connected to the upper side of the base 1 near the bidirectional screw 22. A set of clamping components 24, mounted on the bidirectional screw 22 and used for holding the blended yarns, are respectively connected to both sides of the first slide rod 23. Each clamping component 24 includes a movable frame 241 threadedly connected to the bidirectional screw 22 and slidably connected to the first slide rod 23. A sleeve 242 is rotatably connected to the lower side of the movable frame 241. The sleeve 242 is connected to a bevel gear assembly 243. The upper side of the moving frame 241 is rotatably connected to a turntable 244 driven by the bevel gear assembly 243. The upper side of the turntable 244 is coaxially fixedly connected to a winding rod 245. The upper side of the winding rod 245 is threadedly connected to a nut 246. The front side of the base 1 is fixedly connected to a first motor 21 for driving the bidirectional screw 22. The base 1 is rotatably connected to a cross shaft 26 that is slidably connected to the sleeve 242. The front side of the base 1 is fixedly connected to a second motor 25 for driving the cross shaft 26 to rotate.

[0025] The stretching member 3, mounted on the base 1, is used for stretching blended yarns. The stretching member 3 includes an adjusting member 31 connected to the base 1. The adjusting member 31 is connected to a scale 32 for measuring yarn angles, and a traction wheel 33 is rotatably connected to the center of the scale 32. The output end of the first motor 21 is coaxially and fixedly connected to the bidirectional screw 22. The driving bevel gear in the bevel gear assembly 243 is coaxially and fixedly connected to the sleeve 242, and the driven bevel gear in the bevel gear assembly 243 is coaxially and fixedly connected to the turntable 244. The adjusting member 31 includes two sets of... The base 1 has a second slide bar 311 in the middle, and a third slide bar 312 that is slidably connected to the inner side of the dial 32 is fixedly connected to the upper side of the base 1 near the second slide bar 311. A one-way screw 316 is rotatably connected to the middle of the base 1 along the X-axis. A moving block 314 that is slidably connected to the one-way screw 316 is threaded on the one-way screw 316. A tension sensor 315 for pulling the dial 32 is fixedly connected to the upper end of the moving block 314. A third motor 313 for driving the one-way screw 316 to rotate is fixedly connected to the right side of the base 1.

[0026] The output end of the third motor 313 is coaxially and fixedly connected to the one-way screw 316. The detection end of the tension sensor 315 is fixedly connected to the middle left side of the dial 32. The one-way screw 316 is located between the two sets of second slide rods 311. The traction wheel 33 is located at the axis of the dial 32 and between the two sets of turntables 244. The first motor 21, the second motor 25, and the third motor 313 are all servo motors, which move the frame 241, sleeve 242, and bevel gear assembly 241 within the two sets of clamping parts 24. 43. The turntable 244, winding rod 245, nut 246, second motor 25, and cross shaft 26 cooperate with each other to clamp and straighten the blended yarn on both sides. The second slide rod 311, third slide rod 312, third motor 313, moving block 314, tension sensor 315, one-way screw 316, scale 32, and traction wheel 33 in the tensioning component 3 cooperate with each other to stretch the blended yarn and make it easy for the user to read the deformation angle of the yarn and the tension used to promote the deformation.

[0027] The main difference between the second implementation method and the first implementation method is that:

[0028] The output end of the second motor 25 is coaxially and fixedly connected to the cross shaft 26. The inner side of the sleeve 242 is provided with a cross groove that is slidably connected to the cross shaft 26. The bevel gear assemblies 243 in the two sets of clamping members 24 are symmetrically arranged on both sides of the bidirectional screw 22. The first motor 21 cooperates with the bidirectional screw 22 and the first slide rod 23 to adjust the distance between the two sets of clamping members 24, which helps the subsequent stretching member 3 to stretch the blended yarn held by the clamping members 24 to a suitable angle. During the adjustment process, the sleeve 242 in the clamping member 24 slides along the cross shaft 26, which does not affect the subsequent second motor 25 driving the turntable 244 to rotate through the cross shaft 26, sleeve 242 and bevel gear assembly 243.

[0029] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0030] In use, the user winds one side of the blended yarn to be tested onto the winding rod 245 inside a set of clamping members 24, and rotates the nut 246 on the winding rod 245 to press the yarn onto the turntable 244. This process is repeated to fix the other side of the blended yarn onto another set of clamping members 24. The second motor 25 drives the cross shaft 26 to rotate. Rotating the cross shaft 26, through two sets of sleeves 242 and bevel gear assemblies 243, drives the two sets of turntables 244, the winding rod 245, and the nut 246 to rotate respectively. Since the two sets of bevel gear assemblies 243 are symmetrically arranged on both sides of the bidirectional screw 22, the two sets of turntables 244 rotate in opposite directions and, through the winding rod 245 and the nut 246, wind both sides of the blended yarn to straighten it. The third motor 313 is then started, and the third motor 313, through the unidirectional screw 316, moves the moving block 3. 14. The tension sensor 315, the scale 32, and the traction wheel 33 move horizontally along the X-axis. The scale 32 slides along the third slide bar 312. After the traction wheel 33 contacts the taut blended yarn, it pulls it. The deformation angle of the deformed blended yarn on the scale 32 is observed vertically. At the same time, the tension sensor 315 detects the corresponding tension by pulling the scale 32, the traction wheel 33, and the yarn. After the blended yarn is at the required detection angle, the angle adjustment stops. The clamping member 24 continues to pull both sides of the blended yarn, so that the tension sensor 315 continues to measure the force on the pulled scale 32, the traction wheel 33, and the blended yarn. When the yarn breaks, the magnitude of the force at the breakage angle of the yarn is measured. The tension sensor 315 is existing technology, so its internal structure and working principle will not be described in detail.
