Description

Technical Field

[0001] The present invention relates to the technical field of material strength testing, and particularly to a textile yarn tensile property detection device and a detection method. Background Art

[0002] The purpose of detecting the tensile properties of textile yarns is to comprehensively evaluate their mechanical properties, ensure product quality, optimize production processes, and promote the research and development of new materials; its significance lies in ensuring the safety of material design and use, improving the durability and competitiveness of products. Tensile property detection can measure key indicators such as the strength, elongation, and resilience of textile yarns under tensile loads, and these indicators directly reflect the mechanical properties of the yarns. By comparing the tensile properties of different yarns, the mechanical property characteristics of new materials can be understood, providing a direction for the optimization and improvement of new materials. This helps to promote the innovative development of textile materials and improve the overall quality and competitiveness of textiles.

[0003] In the prior art, for the tensile property detection scheme of textile yarns, it is necessary to first cut the textile yarns, then clamp and fix both ends, and then apply a fixed tensile force from one end to obtain the tensile property data of this section of textile yarn. Therefore, the entire measurement operation involves a large number of pretreatment processes, which results in low measurement efficiency each time, and requires a large amount of manual assistance, increasing the consumption of human resources. Moreover, the textile yarn to be measured is prone to tilting during each clamping, and this phenomenon will affect the final data results of subsequent tensile tests. Therefore, the deviation in the conventional installation process will lead to errors in the results. Summary of the Invention

The output shaft of the motor is connected to the bottom end of the transmission gear set, and the end of the first rotating shaft is connected to the top end of the transmission gear set.

[0009] Further, a fixed rotating arm is welded on the side of the second rotating shaft. A plugging column is welded at the rear end of the fixed rotating arm. The plugging column is embedded inside the inner side of the end of the fixed rotating arm. A second magnetic attraction plate is attached to the surface of the bottom clamping plate.

[0010] Further, stretching grooves are formed on the surfaces of both the bottom clamping plate and the top clamping plate. A clamping plate is embedded inside the stretching groove. A sleeve ring is welded on the side of the clamping plate. A second spring rod is welded on the inner wall of the stretching groove, and the end of the second spring rod is embedded inside the clamping plate. The clamping plate is used for squeezing the textile yarn to be tested.

[0011] Further, the clamping and stretching mechanism includes an electric lifting rod, a pressing rod, and an electric telescopic rod. The top of the electric lifting rod is screwed below the fixed seat, the bottom of the electric lifting rod is welded with a pressure increasing plate, and the bottom of the pressure increasing plate is welded with a pressing rod.

[0012] Further, a tensile sensor is screwed at the end of the electric telescopic rod. The other side of the tensile sensor is screwed on the surface of the lifting track. A third spring rod is inserted on one side of the lifting track, and a vertical plate is installed on the side of the lifting track. An interlocking plate is integrally formed at the bottom of one side of the vertical plate, and a plugging plate is welded at the bottom of the interlocking plate.

[0013] Further, a lifting plate is integrally formed at the top of the vertical plate. The lifting plate is embedded inside the lifting track, and the lifting plate is sleeved on the surface of the third spring rod. The pressing rod is used to abut against the surface of the bearing plate.

[0014] A detection method using the above detection device includes the following steps:

[0015] Step 1: Sleeve the textile yarn to be tested onto the winding and unwinding shaft;

[0016] Step 2: Connect the head part of the textile yarn to the pushing component, start the pushing components on the top layer and the bottom layer, and push one end of the textile yarn by means of the pushing component;

[0020] Step 6: The winding and unwinding shaft automatically cooperates with the pulling of the pushing components on the top layer and the bottom layer to rewire, repeat the stretching test multiple times, and calculate the average stretching performance value.

[0021] The beneficial effects of the present invention:

[0022] 1. When the textile yarn tensile property detection device is in use, a single roll of the textile yarn to be tested is directly sleeved on the surface of the winding and unwinding shaft. After the subsequent pushing component is started, under the clamping and pushing effect of the pushing component, the wound textile yarn can be automatically pulled out, and the positioning and placement process of the fixed-length textile yarn can be completed without prior cutting. It can also automatically provide a high-pressure state, and after the textile yarn breaks due to successive tensile tests, it can still maintain a clamping area and rely on this clamping area to repeat the above process of pulling and routing the yarn, greatly improving the efficiency and coherence of multiple measurements.

[0023] 2. Since the textile yarn tensile property detection device always pulls out the wound textile yarn through the clamping effect between the top pushing component and the bottom pushing component, and the pulling position also remains fixed, it can ensure that each clamping can be close to a fixed straight line direction, reducing the inclination of the textile yarn in the measurement section relative to the tensile direction during each measurement. Compared with the traditional method of separately clamping and fixing both sides, it achieves the effect of automatic extension calibration and improves the accuracy of wire feeding.

[0024] 3. The textile yarn tensile property detection method can continuously measure by directly installing a single roll of the textile yarn to be tested without prior cutting. During the measurement process, it can automatically complete the clamping and stretching processes, greatly improving the measurement efficiency. It also avoids the problem that the two clamping points and the stretching direction are not aligned during clamping, improving the accuracy and reliability of the final detection result.

Specific embodiments

[0034] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0035] Please refer to Figures 1 to 8 , the present invention provides the following technical solutions: a textile yarn tensile property detection device, including a detection device body, the detection device body includes a test bench 1, a clamping and stretching mechanism 8, a top pushing component 6 and a bottom pushing component 7, one end of the surface of the test bench 1 is welded with a winding shaft 2, the surface of the winding shaft 2 is wound with a textile yarn to be tested, the other end of the surface of the test bench 1 is welded with an end plate 3, one side of the top of the end plate 3 is screwed with a clamping and stretching mechanism 8, the front end and the rear end of the surface of the test bench 1 are respectively welded with a front support plate 4 and a rear support plate 5, the middle of the top pushing component 6 is inserted with a first rotating shaft 10, the middle of the bottom pushing component 7 is inserted with a second rotating shaft 21, both the first rotating shaft 10 and the second rotating shaft 21 pass through the inside of the rear support plate 5, the surface of the front support plate 4 is welded with a fixed seat 30, the top of the clamping and stretching mechanism 8 is screwed below the fixed seat 30, the surface of the top pushing component 6 is provided with four top clamping plates 14, and the surface of the bottom pushing component 7 is provided with four bottom clamping plates 23. This detection device is used to detect the single - root tensile strength of the textile yarn to be tested.

[0036] When the present invention is in use, the textile yarn to be measured is sleeved on the winding and unwinding shaft 2, and both ends of the winding and unwinding shaft 2 are movably connected through bearings; the head part of the textile yarn is connected to the pushing assembly. In this state, the head of the textile yarn will have a preliminary clamping effect with one of the top clamping plates 14 and the bottom clamping plate 23. With the help of the pushing assembly, one end of the textile yarn is pushed. As the textile yarn is pulled, the other group of top clamping plates 14 and bottom clamping plates 23 will further clamp another point on the surface of the textile yarn, controlling the textile yarn to contact two positions of the top pushing assembly 6 and the bottom pushing assembly 7 at the same time. The clamping and stretching mechanism 8 is started. First, a downward pressure is applied to each top clamping plate 14 that provides a clamping effect, and then, in cooperation with the contraction movement of the electric telescopic rod 35, the textile yarn between the two clamping areas is stretched; the pulling force is continuously applied until this section of the textile yarn is broken. After breaking, the required pulling force data at the time of breaking is recorded by the pulling force sensor 36; the top pushing assembly 6 and the bottom pushing assembly 7 are restarted to move the textile yarn in the disconnected area. The disconnected part of the textile yarn directly falls downward, and the top clamping plate 14 and the bottom clamping plate 23 that are clamped on the outside are separated from each other and re-form a new clamping area, acting on the newly pulled-out range of the textile yarn, and clamping at two points is completed again; the winding and unwinding shaft 2 automatically cooperates with the pulling of the top pushing assembly 6 and the bottom pushing assembly 7 to rewire, and the stretching test is repeated multiple times to calculate the average stretching performance value.

[0037] In this embodiment, the top pushing assembly 6 includes a telescopic sleeve 11, a telescopic rotating arm 12 and a top clamping plate 14. The telescopic sleeve 11 is welded to the surface of the first rotating shaft 10. A first magnetic attraction plate 16 is attached to the bottom surface of the top clamping plate 14, and a pressure increasing rod 17 is inserted through the middle of the top clamping plate 14. The top end of the pressure increasing rod 17 is welded with a bearing plate 18. The telescopic rotating arm 12 is embedded inside the telescopic sleeve 11. A first spring rod 13 is inserted at the end of the telescopic rotating arm 12, and the end of the first spring rod 13 is fixed on the inner wall of the telescopic sleeve 11. A plugging sleeve 15 is integrally formed on the surface of the top clamping plate 14, and the end of the telescopic rotating arm 12 is embedded inside the plugging sleeve 15 through a rod.

[0038] Specifically, part of the top pushing component 6 is cooperated with the motor 19 at the backend and the transmission case 9 to drive the first rotating shaft 10 to rotate, and at the same time drive each top clamping plate 14 on the surface to rotate. Since the top pushing component 6 and the bottom pushing component 7 are linked by a transmission gear set 20, the top clamping plate 14 and the bottom clamping plate 23 will rotate synchronously. The two clamping plates will come into contact and fit in the middle area. And because the top clamping plate 14 is sleeved on the end of the telescopic rotating arm 12 through the insertion sleeve 15, the entire top clamping plate 14 droops due to its own gravity and will always face the first magnetic attracting plate 16 downward. And part of the top clamping plate 14 is attached with a weight block in the middle area below, so as to control the second magnetic attracting plate 24 to be always vertically arranged facing the top position.

[0039] In this embodiment, the bottom pushing component 7 includes a motor 19, a fixed rotating arm 22 and a bottom clamping plate 23. A transmission case 9 is welded on the outside of the rear-end support plate 5. A transmission gear set 20 is installed inside the transmission case 9. The output shaft of the motor 19 is connected to the bottom end of the transmission gear set 20. The end of the first rotating shaft 10 is connected to the top end of the transmission gear set 20. A fixed rotating arm 22 is welded on the side of the second rotating shaft 21. An insertion column 29 is welded at the rear end of the fixed rotating arm 22. The insertion column 29 is embedded in the inner side of the end of the fixed rotating arm 22. A second magnetic attracting plate 24 is attached to the surface of the bottom clamping plate 23. Tensile grooves 25 are formed on the surfaces of the bottom clamping plate 23 and the top clamping plate 14. A clamping plate 27 is embedded in the tensile grooves 25. A collar 28 is welded on the side of the clamping plate 27. A second spring rod 26 is welded on the inner wall of the tensile groove 25. The end of the second spring rod 26 is embedded in the clamping plate 27. The clamping plate 27 is used to squeeze the textile yarn to be measured. Directly sleeve a single roll of the textile yarn to be measured on the surface of the winding shaft 2. After the pushing component is started subsequently, under the clamping and pushing effect of the pushing component, the wound textile yarn can be automatically pulled out, and the positioning and placing process of the fixed-length textile yarn can be completed without pre-cutting treatment. It can also automatically provide a high-pressure state subsequently. And after the textile yarn breaks due to a stretching test in sequence and one clamping area can still be maintained, the above-mentioned pulling and wiring process can be repeated relying on this clamping area, greatly improving the efficiency and coherence of multiple measurements.

[0040] Specifically, through the rotation process of the above-mentioned motor 19 and transmission gear set 20, the top clamping plate 14 and the bottom clamping plate 23 can be controlled to rotate synchronously, and the part of the textile yarn that has been pulled out can be contacted and clamped at the intersection of the top clamping plate 14 and the bottom clamping plate 23. After clamping, the first magnetic attraction plate 16 and the second magnetic attraction plate 24 are used to increase the clamping force, ensuring that the clamping plates 27 on the upper and lower sides generate sufficient pulling force on the textile yarn. As the top clamping plate 14 and the bottom clamping plate 23 continue to rotate, the telescopic rotating arm 12 on the top clamping plate 14 is pushed by the fixed rotating arm 22 on the side of the bottom clamping plate 23, causing the telescopic rotating arm 12 to contract into the interior of the telescopic sleeve 11, and the first spring rod 13 is compressed until it passes through the connection area between the first rotating shaft 10 and the second rotating shaft 21. At this time, the telescopic rotating arm 12 expands again until the textile yarn is pulled to the other side, and the above process is repeated to form two clamping points. At this time, the clamping and stretching mechanism 8 can be started to complete the subsequent pressurization and testing processes. In this process, the top pushing component 6 and the bottom pushing component 7 complete the synchronous rotation movement process through a single motor 19 and a transmission gear set 20. The transmission gear set 20 is an existing mature technology and does not fall within the protection scope of the present invention. Therefore, the specific structure and principle of the transmission gear set 20 will not be described in detail here.

[0041] In this embodiment, the clamping and stretching mechanism 8 includes an electric lifting rod 31, a pressing rod 33 and an electric telescopic rod 35. The top of the electric lifting rod 31 is screwed below the fixed seat 30, and the bottom of the electric lifting rod 31 is welded with a pressurizing plate 32. The bottom of the pressurizing plate 32 is welded with a pressing rod 33. The end of the electric telescopic rod 35 is screwed with a tensile force sensor 36, and the other side of the tensile force sensor 36 is screwed on the surface of the lifting track 37. A third spring rod 38 is inserted on one side of the lifting track 37, and a vertical plate 39 is installed on the side of the lifting track 37. A linkage plate 34 is integrally formed at the bottom of one side of the vertical plate 39, and a plug-in plate 41 is welded to the bottom of the linkage plate 34. A lifting plate 40 is integrally formed at the top of the vertical plate 39. The lifting plate 40 is embedded in the interior of the lifting track 37, and the lifting plate 40 is sleeved on the surface of the third spring rod 38. The pressing rod 33 is used to abut against the surface of the bearing plate 18. Since the clamping effect between the top pushing component 6 and the bottom pushing component 7 is always used to pull out the coiled textile yarn, and the pulling-out position is also always fixed, it can be ensured that each clamping can be close to the fixed straight line direction, reducing the inclination of the measured section of the textile yarn relative to the stretching direction during each measurement. Compared with the traditional method of clamping and fixing the two sides separately, the effect of automatic extension calibration is achieved, and the accuracy of wire feeding is improved.

[0042] Specifically, in the state of pushing the textile yarn, both the electric telescopic rod 35 and the electric lifting rod 31 are in the contracted state. Therefore, the pressure-increasing plate 32 and the pressing rod 33 move upward to avoid interfering with the rotation and pushing process of the top clamping plate 14 and the bottom clamping plate 23. When it is necessary to increase the pressure on the top clamping plate 14, start the electric lifting rod 31 to extend, and push the bottom pressing rod 33 against the bearing plate 18 on the surface of the two top clamping plates 14 below, then the clamping plate 27 on the top clamping plate 14 can be pressed down to increase the clamping force applied to the textile yarn. During this process, the electric telescopic rod 35 will also be controlled to extend, and the linkage plate 34 will be embedded between the pressing rod 33 and the pressure-increasing plate 32. At this time, the pressure-increasing plate 32 can press down on the linkage plate 34, and the plug-in plate 41 is simultaneously embedded into the collar 28 on the side of the clamping plate 27 in contact with the end of the textile yarn. At this time, start the electric telescopic rod 35, and the two clamping plates 27 on this side can be pulled to achieve the effect of stretching the textile yarn. Until it is broken, the maximum tensile force data displayed by the tensile force sensor 36 before breaking can be recorded.

[0043] This embodiment also provides a detection method using the above detection device, including the following steps:

[0044] Step 1: Sleeve the textile yarn to be tested onto the winding shaft 2, and both ends of the winding shaft 2 are movably connected through bearings;

[0045] Step 2: Connect the head part of the textile yarn to the pushing assembly. In this state, a preliminary clamping effect will be generated between the head of the textile yarn and one of the top clamping plates 14 and the bottom clamping plate 23, and start the top and bottom pushing assemblies to push one end of the textile yarn with the help of the pushing assembly;

[0046] Step 3: As the textile yarn is pulled, another set of top clamping plates 14 and bottom clamping plates 23 will further clamp another point on the surface of the textile yarn, control the textile yarn to contact two positions of the top pushing assembly 6 and the bottom pushing assembly 7 at the same time, and start the clamping and stretching mechanism 8 to stretch the textile yarn between the two clamping areas;

[0047] Step 4: Continuously apply tensile force until this section of the textile yarn is broken, and record the required tensile force data at the time of breaking through the tensile force sensor 36 after breaking;

[0048] Step 5: Restart the top pushing assembly 6 and the bottom pushing assembly 7 to move the textile yarn in the disconnected area. The disconnected part of the textile yarn directly drops towards the bottom, and the top clamping plate 14 and the bottom clamping plate 23 that are clamped on the outside are separated from each other, and a new clamping area is formed again, acting on the newly pulled-out range of the textile yarn to re-clamp the two points;

[0049] Step 6: The winding and unwinding shaft 2 automatically cooperates with the pulling of the top layer pushing component 6 and the bottom layer pushing component 7 to rewire, repeats the stretching test multiple times, and calculates the average stretching performance value.

[0050] The above method can directly install a single roll of the textile yarn to be tested and continuously measure it without prior cutting. Moreover, the clamping and stretching processes can be automatically completed during the measurement, greatly improving the measurement efficiency. It also avoids the problem that the two clamping points and the stretching directions are not aligned during clamping, improving the accuracy and reliability of the final detection result.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms.

[0052] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

The pressing rod (33) is used to abut against the surface of the bearing plate (18).

10. A detection method using the detection device as described in claim 1, characterized in that, Including the following steps: Step 1: Sleeve the textile yarn to be measured onto the winding and unwinding shaft. Step 2: Connect the head part of the textile yarn to the pushing component. Start the pushing components at the top layer and the bottom layer. With the help of the pushing components, push one end of the textile yarn. Step 3: Control the textile yarn to be in contact with two positions of the top layer pushing component and the bottom layer pushing component at the same time. Start the clamping and stretching mechanism to stretch the textile yarn between the two clamping areas. Step 4: Continuously apply a pulling force until the section of the textile yarn is broken, and record the required pulling force data at the moment of breaking through the tension sensor. Step 5: Restart the pushing components at the top layer and the bottom layer, move the textile yarn in the disconnected area, and re-clamp the two positions. Step 6: The winding and unwinding shaft automatically cooperates with the pulling of the pushing components at the top layer and the bottom layer to re-arrange the wire. Repeat the stretching test multiple times and calculate the average stretching performance value.
