Description

Technical Field

[0001] The present invention relates to the technical field of yarn strength detection, and specifically to a textile yarn strength detection device. Background Technique

[0002] As the basic constituent unit of textiles, the strength performance of yarns is directly related to the quality and durability of textiles. Therefore, during the textile production process, strength detection of yarns is a key link to ensure product quality. Through strength detection, performance indicators such as the tensile strength and elastic modulus of yarns can be evaluated, so as to determine whether they meet relevant standards and design requirements. When existing single yarn strength testing machines are in use, manual yarn clamping, manual yarn transfer, and yarn replacement are required. The operation steps are cumbersome, and manual operation step by step takes a long time. Not only is the work efficiency low, but the labor cost is also relatively high.

[0003] In the prior art, such as a fully automatic single yarn strength testing machine with the publication number CN219475201U, the automatic sampling arm rotates to one end of the sample, picks up the sample and then rotates to the upper clamping device. Subsequently, the lower clamping device moves upward to the upper clamping device to clamp the sample. Then, it gradually moves downward to stretch the sample. After the detection is completed, the wire is automatically cut by the wire cutter, and the sample position is adjusted by the material changing mechanism. Through the above technical solution, automatic yarn clamping, automatic yarn transfer, automatic yarn replacement, automatic wire cutting, and automatic stretching can be achieved, with a relatively high degree of automation, convenient use, and high work efficiency.

[0004] However, during actual use, when conducting multi-tube tests, the traditional pneumatic clamping structure uses a relatively long pneumatic hose to connect to the lower gripper. During mobile testing, the hose is prone to bending, which easily causes airway blockage, thus affecting the clamping effect of the yarn. In addition, when the yarn breaks during multiple tests, the broken yarn quickly bounces towards the gripper, and some fine yarn fluffs are generated by the broken yarn, which accumulate on the gripper and cause interference.

[0005] Therefore, the present invention proposes a textile yarn strength detection device to solve the problem that the traditional pneumatic clamping structure uses a relatively long pneumatic hose to connect to the lower gripper, and during mobile testing, the hose is prone to bending, which easily causes airway blockage, thus affecting the clamping effect of the yarn.

[0033] In order to clearly and completely describe the purpose, technical solution of the present invention and make the advantages more clearly understood, the following further details the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

[0034] Embodiment 1, please refer to Figure 1-13The present invention provides a technical solution: a textile yarn strength detection device, comprising a fully automatic yarn strength machine 1, a lifting seat 12 is slidably connected to the front side of the fully automatic yarn strength machine 1, an upper clamp 11 and a lower clamp 2 are arranged on the front side of the fully automatic yarn strength machine 1, the fully automatic yarn strength machine 1 is fixedly installed on the upper outer surface of the fully automatic yarn strength machine 1, the inner surface of the lower clamp 2 is movably connected to the outer surface of the lower clamp 2, the lower end of the lower clamp 2 is fixedly connected to a connecting guard plate 21, a mounting plate 22 and an operation box 23 are arranged on the inner side of the lower end of the connecting guard plate 21, a pneumatic clamping mechanism is arranged between the lower clamp 2 and the connecting guard plate 21, the pneumatic clamping mechanism includes an operating assembly, a gas replenishing assembly and a piston assembly 26, and a moving guide mechanism is arranged on the outer sides of the lower clamp 2 and the upper clamp 11; The mobile guide mechanism comprises a guide slope 201 and a contact steel plate 202. The guide slope 201 is arranged on both sides of the contact steel plate 202. A mounting groove 2010 is provided on the inner wall of the guide slope 201. A guide roller 2011 is rotatably installed on the inner surface of the mounting groove 2010. The mounting plate 22 is rotatably connected to the lifting seat 12 through a shaft 211. The lifting seat 12 is lifted and lowered on the surface of the full-automatic yarn strength machine 1 through a cylinder. An arc-shaped limiting groove 223 is provided on the outer side of the lifting seat 12. A curved spring 222 is fixedly connected to the inner wall of the arc-shaped limiting groove 223. The other end of the curved spring 222 is fixedly connected to a limiting column 221. The limiting column 221 is fixedly installed on the outer surface of one side of the mounting plate 22 close to the lifting seat 12. The outer surface of the limiting column 221 is movably connected to the inner wall of the arc-shaped limiting groove 223.

[0035] When testing the strength of textile yarn, the cylinder drives the lifting seat 12 to move in the vertical direction, the upper end of the yarn is clamped by the upper clamp 11, and the lower end of the yarn is clamped by the lower clamp 2. At this time, the lifting seat 12 drives the lower clamp 2 to move downward, and the yarn is pulled at the set value until the yarn breaks, and the test value is obtained to detect the strength of the yarn on different bobbins. It should be noted that a moving guide mechanism is designed on the outer side of the upper clamp 11 and the lower clamp 2. When the lower clamp 2 moves up to take the yarn, it passes through the guide slope 201 below the upper clamp 11. And the guide of the contact steel plate 202, the connecting guard plate 21, the mounting plate 22, the operating box 23 and the overall structure of the lower clamp 2 are slightly tilted to one side. At this time, the limit column 221 moves on the arc limit groove 223, and the curved spring 222 is squeezed to produce compression deformation. When the lower clamp 2 rises to the upper position of the upper clamp 11, the connecting guard plate 21 and the lower clamp 2 are straightened by the reverse elastic force of the curved spring 222. At this time, one end of the yarn is clamped by the pneumatic clamping mechanism, and then the cylinder is started to drive the lower clamp 2 to move downward to realize the yarn strength test.

[0036] Embodiment 2, refer to the attached Figure 1-13, on the basis of Embodiment 1, in order to trigger the lifting movement of the piston assembly 26: The operating assembly includes a piston cylinder body 24, which is fixedly installed inside the operating box 23. The inner cavity of the piston cylinder body 24 is provided with a piston cavity 240. On one inner wall of the piston cavity 240, a lower air inlet 2401 and an upper air inlet 2402 are respectively opened. The gas supply assembly includes a mounting side plate 25 and a booster pump 251. The booster pump 251 is fixedly installed outside the operating box 23 through the mounting side plate 25. The output end of the booster pump 251 is provided with a gas adapter. The gas adapter is respectively connected with an upper booster air pipe 252 and a lower booster air pipe 253. The outer surface of the upper booster air pipe 252 is adapted to and corresponds to the inner wall of the upper air inlet 2402, and the outer surface of the lower booster air pipe 253 is adapted to and corresponds to the inner wall of the lower air inlet 2401; The piston assembly 26 is composed of a piston member 261 and a rod member 262. The piston member 261 is movably installed inside the piston cavity 240. A sealing port 2610 is opened on the upper surface of the piston member 261. A sealing block 2611 is movably connected inside the sealing port 2610. The bottom of the sealing block 2611 is fixedly connected with a contact spring wire 2612. The other end of the contact spring wire 2612 is fixedly connected with the bottom surface of the inner cavity of the sealing port 2610; A first air guiding channel 2613 is connected through the upper inner wall of the sealing port 2610. The output end of the first air guiding channel 2613 extends to the upper end of the rod member 262. A gas gathering hood 2621 is fixedly connected to the outer surface of the upper end of the rod member 262;

[0037] When it is necessary to change the position of the piston assembly 26 by relying on gas, the booster pump 251 is installed on one side of the operating box 23 through the mounting side plate 25. The booster pump 251 is activated to convey pressurized gas into the inner cavity of the piston cavity 240. When the pressurized gas enters the bottom of the piston member 261 from the lower air inlet 2401, the bottom of the piston member 261 is continuously pushed upward by the action of the pressurized gas. At this time, the piston member 261 drives the rod member 262 to move upward. When the pressurized gas enters the upper cavity position of the piston cavity 240 through the upper air inlet 2402, the piston member 261 moves downward under the influence of the upper pressurized gas. At this time, the rod member 262 moves downward. When the connecting block 2641 connected to the upper end of the rod member 262 can no longer move downward, the pressurized gas at this time pushes the sealing block 2611 in the sealing port 2610 downward. At this time, the contact spring wire 2612 is compressed. Subsequently, after the sealing block 2611 moves downward, the input port of the first air guiding channel 2613 is opened. At this time, the pressurized gas is output through the first air guiding channel 2613 and output through the top of the rod member 262. It should be noted that a gas gathering hood 2621 is additionally installed at the top position of the rod member 262. Here, the high-speed airflow is concentrated towards the middle, thereby increasing the speed of the ejected gas. The ejection of the pressurized gas here can achieve auxiliary dust removal between the two wire clamping plates 203 and avoid the interference of yarn fluffs adhesion on subsequent detection work.

[0038] Embodiment 3, referring to the attachedFigure 1-13 On the basis of the second embodiment, in order to realize the relative movement of the two groups of clamping plates 203 by pneumatic means to realize the clamping of the yarn: the outer surface of the piston assembly 26 is movably connected to the inner wall of the upper end of the piston cylinder 24, and a socket plate 263 is fixedly installed on the outer surface of the upper end of the piston assembly 26, and a movable wing plate 264 is fixedly connected to the upper end of the socket plate 263, and a connecting block 2641 is fixedly installed on the inner side of the upper end of the movable wing plate 264, and an inner inclined surface of the connecting block 2641 is provided with an inclined surface 1 26410; a yarn threading groove 20 is provided on the inner wall of the lower clamp 2, and a movable groove 200 is provided through the inner side of the yarn threading groove 20, and a clamping plate 203 is movably connected to the inner side of the movable groove 200, and a connecting rod 2031 is fixedly connected to the back side of the clamping plate 203, and an inclined surface 20310 is provided at the end of the connecting rod 2031 away from the clamping plate 203, The outer surface of the second surface 20310 is movably connected with the outer surface of the inclined surface 1 26410, and an avoidance slide groove 2000 is provided at the lower end of the movable groove 200, and the inner surface of the avoidance slide groove 2000 is slidably connected with the outer surface of the movable wing plate 264, and the inner side of the clamping plate 203 is fixedly connected with a connecting strip 2032, and the outer surface of the connecting strip 2032 is fixedly connected with a spring 2033, and the other end of the spring 2033 is fixedly connected with the side wall of the movable groove 200; a broken yarn collecting tube 27 is fixedly connected to the inside of the operating box 23, and a connecting hose 271 is connected to the lower end of the broken yarn collecting tube 27, and a negative pressure device is provided at the other end of the connecting hose 271, and a collecting box 272 is provided at the output end of the connecting hose 271, and a negative pressure collecting system is formed by the broken yarn collecting tube 27, the connecting hose 271 and the collecting box 272 to realize the collection of broken yarns;

[0039] When the yarn is between the yarn threading slots 20, the two sets of clamping plates 203 are in a separated state and are recovered to the inner side of the yarn threading slots 20 under the action of the spring 2033. When the rod 262 is lifted, the sleeve plate 263 and the movable wing plate 264 move upward. At this time, the inclined surface 1 26410 of the connecting block 2641 contacts the inclined surface 20310 at one end of the connecting rod 2031. The gradually moving connecting block 2641 pushes the connecting rod 2031 and the clamping plate 203 to move closer to the middle. At this time, the spring 2 033 is in a stretched state until the two sets of clamping plates 203 clamp the central yarn. Here, the clamping force of the clamping plates 203 on the yarn can be adjusted by adjusting the lifting height of the rod 262, which is convenient for the diversity and accuracy of the yarn strength test data; when the yarn needs to be loosened, it is only necessary to drive the rod 262 downward through pneumatic action, so that the connecting block 2641 releases the support of the connecting rod 2031, so as to ensure that the clamping plate 203 returns to its initial position under the reverse elastic action of the spring 2033;

[0040] It should be noted that when the wire clamping plate 203 gradually opens to both sides, the restriction on the yarn is released. At this time, the negative pressure device is turned on to suck the broken yarn into the interior of the collection box 272 for collection. After the yarn is sucked away, the air guide channel 2613 blows air specifically at the position of the wire clamping plate 203 to avoid the situation where the yarn fluffs adhered to the wire clamping plate 203 are not completely cleaned up.

[0041] Embodiment 4. Refer to the appendix Figure 1-13 , on the basis of Embodiment 3, in order to avoid the situation where the piston assembly 26 gets stuck during operation and affects the testing work: an annular groove 2615 is opened on the lower inner wall of the piston member 261. The inner ring side surface of the annular groove 2615 is connected throughly with an air guide channel 2614. One end of the air guide channel 2614 is connected throughly with the air guide channel 2613; an activity groove 26150 is opened on the annular cavity side wall of the annular groove 2615. One end of the activity groove 26150 is fixedly connected with a reset spring wire 26151. The other end of the reset spring wire 26151 is fixedly connected with a push block 26152. The outer surface of the push block 26152 is slidably connected with the inner wall of the activity groove 26150. An infiltration cotton ring 26153 is arranged on the outer side of the push block 26152. Both ends of the infiltration cotton ring 26153 are respectively abutted against the inner wall of the activity groove 26150. A ball 26154 is arranged on the side of the infiltration cotton ring 26153 away from the push block 26152; a rolling groove is throughly opened on the side of the annular groove 2615 away from the activity groove 26150. The ball 26154 is movably installed inside the rolling groove, and the outer surface of the ball 26154 is movably connected with the inner wall of the piston cavity 240;

[0042] Refer to Figure 11 As shown, when the pressurized gas above the piston member 261 is saturated and the gas enters through the port of the air guide channel 2613, a small part of the pressurized gas flows through the air guide channel 2614. At this time, the gas enters the inside of the annular groove 2615, first pushes the push block 26152 to move outwards, and at this time the reset spring wire 26151 is stretched. The outwardly pushed push block 26152 squeezes the inside of the outer infiltration cotton ring 26153. The infiltration cotton ring 26153 extrudes the infiltrated lubricating oil, and the lubricating oil contacts the surface of the ball 26154 on one side. In this way, when the piston member 261 moves inside the piston cavity 240, an oil film is formed in the cavity through the rolling of the ball 26154. In this way, the smoothness of the piston member 261 when pushed by the pressurized gas is increased, and the situation where the piston assembly 26 gets stuck during movement is avoided, further improving the stability of the textile yarn strength detection.

[0043] Embodiment 5. Refer to the appendix Figure 1-13 , on the basis of Embodiment 4, the present invention also proposes a usage method of a textile yarn strength detection device, including the following steps:

[0044] Step 1: Load multi-end yarns on the top of the fully automatic yarn strength tester 1 through bobbins. Clamp one end of the yarn with the upper gripper 11. Start the cylinder by operating the control panel to drive the lower gripper 2 to the upper part of the upper gripper 11 to clamp the yarn. Adjust the lifting speed and clamping force of the cylinder to ensure that the yarn can be evenly stressed during the test.

[0045] Step 2: After the yarn is clamped by the upper and lower grippers, start the test program by operating the control panel. The cylinder will drive the lower gripper 2 to move downward to pull the yarn until the yarn breaks. Record the data during the test, such as the tensile force value and the breaking position when the yarn breaks, for subsequent analysis and evaluation of the yarn strength.

[0046] Step 3: After the yarn breaks, the lower gripper 2 clamps the broken yarn. Connect the hose 271 to the negative pressure device, and introduce the broken yarn end into the collection box 272 through the broken yarn collection tube 27 for collection.

[0047] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
