Description

Technical Field

[0001] This invention relates to the field of textile tensile strength testing technology, specifically a textile tensile strength testing device. Background Technology

[0002] Tensile strength testing is one of the important methods for evaluating the tensile properties of fabric materials. The tensile strength of a fabric refers to the maximum tensile force that the fabric material can withstand before breaking under tensile load. It is one of the important indicators for evaluating the quality of fabric materials. By testing the tensile strength of a fabric, we can understand the strength, elongation and breaking performance of the fabric, which has important reference value for the design, selection and application of fabrics.

[0003] Existing textile tensile strength testing devices can obtain the tensile strength of textiles by stretching the fabric or yarn and supplementing it with tensile force monitoring and control, or by observing the fiber breakage state. However, in practical applications, the testing devices generally only act on a single textile yarn or fabric. For different stages of textile processing, it is difficult to meet the corresponding testing requirements to determine the factors affecting tensile strength, and it is also difficult to provide technical reference for optimizing textile processing technology and raw material ratio.

[0004] An automatic testing device and method for multi-directional tensile strength of textiles based on constant tension (publication number CN120507214A) integrates an optical response mechanism for high-elastic fabrics. When testing the tensile strength of fabrics, the device can monitor the fabric transmittance and the changes in light spots formed by light passing through the fabric in stages by illuminating the fabric with a light source. This enables visualization of microscopic fiber damage and reflects the progressive fiber fracture damage process, thus also reflecting the aforementioned problems to a certain extent.

[0005] Therefore, how to provide a device for testing the tensile strength of textiles is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] To overcome the shortcomings of existing textile tensile strength testing devices, which generally only operate on single textile threads or fabrics, making it difficult to meet the corresponding testing needs for different stages of textile processing to determine the factors affecting tensile strength, and also making it difficult to provide technical references for textile processing optimization and raw material ratio, this application provides a textile tensile strength testing device. A pneumatic push rod controls a multi-fork drive frame to move downwards. A pressure rod pinned to one end of one of the multiple forks of the multi-fork drive frame rotates around the hinge point between the drive arm and the second and first support seats within the corresponding slot of the drive arm. This allows the multi-fork drive frame to control multiple support arc plates to converge towards the center or expand outwards. Simultaneously, a synchronous upright applies pressure to the top of the adjustment component. When under pressure, the adjustment component moves within the cover, causing the sliding plate to move within the first receiving column slot. Multiple second springs then apply pressure to the movable pressure plate, supporting a pressure sensor to acquire pressure data, ultimately obtaining the tensile strength data of the textile. Meanwhile, by using the anti-slip ribs staggered on the U-shaped frame and bracket to clamp and fix the end, when the pneumatic push rod controls the multi-fork drive frame to drive multiple pressure rods inside the strip groove of the drive arm at the corresponding position, on the one hand, it controls multiple support arc plates to expand outward, tightening the textile threads or fabric, and on the other hand, it causes the U-shaped frame to slide inside the cylindrical cover, and causes the support upright to slide inside the cylindrical cover, compressing the first spring between the cover and the bracket, further clamping the textile thread end or fabric between the U-shaped frame and the bracket.

[0008] In one possible implementation, the protective cover includes a door cover, and multiple cylindrical covers are welded to all four sides of the door cover; the interiors of the multiple cylindrical covers are all connected to the interior of the door cover, two guide crossbars on the support arc plate are slidably connected to the interior of one cylindrical cover, and the drive arm is movably connected to the inside of the cylindrical cover.

[0009] In one possible implementation, rollers are mounted on the bottom of each of the multiple supporting arc plates, and multiple storage slots are provided around the base of the testing device; the bottom surface of the rollers is flush with the bottom surface of the base of the testing device, and the rollers mounted on the bottom of the multiple supporting arc plates are movably connected to the inside of the multiple storage slots.

[0010] In one possible implementation, guide arc plates are integrally formed on both sides of the supporting arc plate, and multiple limiting ball heads are processed on the surface of the guide arc plate away from the supporting arc plate, with the multiple limiting ball heads arranged at equal intervals in the longitudinal direction.

[0011] In one possible implementation, a first storage groove is provided at the top of the central prism, a second storage groove is provided at the bottom of the central prism, and an installation slot is provided at the center of the test device base; the interior of the installation slot is connected to the interior of the second storage groove, and the pressure sensor is assembled and fixed to the central prism through the interior of the installation slot and the second storage groove, with its top extending into the interior of the first storage groove.

[0012] In one possible implementation, the top of the central prism is fitted with a cover, the adjusting assembly includes a movable pressure plate, the top of the movable pressure plate is provided with a sliding plate, a plurality of second springs are provided between the movable pressure plate and the sliding plate, a connecting column is welded to the center of the top of the sliding plate, and the side of the top of the connecting column is machined with mutually symmetrical straight cut surfaces; the adjusting assembly is disposed inside the first receiving column groove, the top of the connecting column and the bottom of the synchronous column are threadedly connected, and the connecting column is slidably connected inside the cover.

[0013] In one possible implementation, the top of the movable pressure plate is welded with multiple guide rods, which are equally spaced around the center of the movable pressure plate. Multiple second springs are respectively sleeved on the outside of the multiple guide rods, and the sliding plate is slidably connected to the outside of the multiple guide rods.

[0014] In one possible implementation, the fixing component includes a U-shaped frame with a bracket on its inner side, and limit pins are pinned to both sides of the bottom of the U-shaped frame; the limit pins are pinned to the interior of the multi-fork drive frame, the U-shaped frame is slidably connected to the interior of the cylindrical cover, and the bracket is located at the top of the cover.

[0017] The beneficial effects of this application are as follows: Firstly, in this solution, the pneumatic push rod controls the multi-fork drive frame to move downwards. The pressure rod, pinned to one end of one of the multiple forks of the multi-fork drive frame, rotates around the hinge point between the drive arm and the second and first support seats in the corresponding slot of the drive arm. This allows the multi-fork drive frame to control multiple support arc plates to retract towards the center or expand outwards. Simultaneously, the synchronous upright applies pressure to the top of the adjustment component. When the adjustment component is under pressure, the connecting column moves inside the cover, driving the sliding plate inside the first storage column slot to apply pressure to the movable pressure plate using multiple second springs. This supports the pressure sensor to acquire pressure data, ultimately obtaining the tensile strength data of the textile. Secondly, in this solution, the ends are clamped and fixed by means of anti-slip ribs staggered on the U-shaped frame and bracket. When the pneumatic push rod controls the multi-fork drive frame to drive multiple pressure rods inside the strip groove of the drive arm at the corresponding position, on the one hand, multiple support arc plates are controlled to expand outward to tighten the textile threads or fabrics.

[0020] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows: Example 1: This embodiment describes the specific structure of a textile tensile strength testing device, which can be referred to in detail below. Figures 1 to 4 , Figures 7 to 9 As shown, the device includes multiple supporting arc plates 4, a test device base 1 disposed at the bottom of the multiple supporting arc plates 4, and a drive assembly 2 disposed between the multiple supporting arc plates 4. Limiting rings 7 are machined on the outer surfaces of the top and bottom of the multiple supporting arc plates 4. A central prism 15 is integrally formed at the center of the top of the test device base 1. A pressure sensor 11 and an adjustment assembly 18 are disposed inside the central prism 15. The adjustment assembly 18 is located on top of the pressure sensor 11. A protective cover 8 is assembled and connected to the top of the test device base 1. The multiple supporting arc plates 4 are equally spaced around the protective cover 8. Two guide crossbars 203 are threadedly connected to the side surface of the multiple supporting arc plates 4 facing the protective cover 8. Multiple movable slots 14 are opened inside the protective cover 8. Multiple fixing assemblies 3 are disposed around the top of the protective cover 8. The drive assembly 2 includes a pneumatic push rod 201. The bottom of the pneumatic push rod 201 is assembled and connected to a multi-fork drive frame 207. Each end of one of the multiple forks of the multi-fork drive frame 207 is pinned to a pressure rod 208. Multiple drive arms 202 are arranged around the multi-fork drive frame 207. Each drive arm 202 has a slot 16 inside. The two ends of the multiple drive arms 202 are respectively hinged to a second support seat 205 and a first support seat 204. The bottom of the multi-fork drive frame 207 is welded and connected to a synchronous upright 206. The protective cover 8 includes a door cover 802, and multiple cylindrical covers 801 are welded to all four sides of the door cover 802. The interior of the multiple cylindrical covers 801 is connected to the interior of the door cover 802. The central prism 15 has a first storage groove 12 at its top and a second storage groove 19 at its bottom. The test device base 1 has an installation slot 10 at its center. By connecting the interior of the installation slot 10 with the interior of the second storage groove 19, the pressure sensor 11 is assembled and fixed to the central prism 15 through the interior of the installation slot 10 and the second storage groove 19, and its top extends into the interior of the first storage groove 12, which can support the pressure sensor 11 to acquire pressure data. Secondly, the drive arm 202 is movably connected to the inside of the cylindrical cover 801. One side of the second support seat 205 is fixedly assembled with the side surface of the support arc plate 4 facing the cover 8. One side of the first support seat 204 is fixedly assembled with the surface of the central prism 15. Multiple pressure rods 208 are slidably connected to the inside of the strip grooves 16 on the multiple drive arms 202, driving the drive arm 202 to rotate around the hinge point with the second support seat 205 and the first support seat 204. Thus, when the drive assembly 2 controls the multiple support arc plates 4 to retract towards the center or expand outwards, the two guide crossbars 203 on the support arc plate 4 are slidably connected to the inside of a cylindrical cover 801 to control the path of the multiple support arc plates 4 during the movement process. The movement of the multiple support arc plates 4 can be controlled synchronously. Furthermore, the textile threads or fabric to be tested are wound around the outside of multiple support arc plates 4, and any two fixed ends of multiple fixing components 3 can simultaneously apply pressure to the top of the adjustment component 18 by using the synchronous upright rod 206 while the pneumatic push rod 201 controls the multi-fork drive frame 207 to move the multiple support arc plates 4 and apply pressure to the textile threads or fabric. The support pressure sensor 11 obtains pressure data, and in conjunction with existing fiber tensile strength judgment technology, the tensile strength data of the textile is obtained. Furthermore, in order to reduce the resistance caused by the weight of the supporting arc plates 4 when the drive component 2 controls the multiple supporting arc plates 4 to retract towards the center or expand outwards, such as Figure 1 and Figure 2 As shown, rollers 6 are assembled and connected to the bottom of multiple supporting arc plates 4. Multiple storage slots 5 are opened around the base 1 of the test device. By making the bottom surface of the rollers 6 flush with the bottom surface of the base 1 of the test device, during the process of the drive component 2 controlling the movement of multiple supporting arc plates 4, the rollers 6 assembled at the bottom of multiple supporting arc plates 4 are respectively movably connected to the inside of multiple storage slots 5 and roll on the table surface on which the base 1 of the test device is installed, which can reduce the movement resistance of multiple supporting arc plates 4. In some examples, the two sides of the supporting arc plate 4 are integrally formed with guide arc plates 13, and the surface of the guide arc plate 13 away from the supporting arc plate 4 is machined with multiple limiting ball heads 9. Among them, multiple limiting ball heads 9 are arranged at equal intervals in the longitudinal direction. When the textile threads or fabric to be tested are wrapped around the outside of multiple supporting arc plates 4 and fixed by any two of the multiple fixing components 3, the winding state of the textile threads or fabric can be controlled by limiting ball heads 9 of different heights.

[0021] like Figure 7 and Figure 8 As shown, the top of the central prism 15 is fitted with a cover 17, the adjustment assembly 18 includes a movable pressure plate 1802, the top of the movable pressure plate 1802 is provided with a sliding plate 1801, a plurality of second springs 1805 are provided between the movable pressure plate 1802 and the sliding plate 1801, and a connecting column 1803 is welded to the center of the top of the sliding plate 1801, and the side of the top of the connecting column 1803 is machined with mutually symmetrical straight cut surfaces 20; In this way, by setting the adjustment component 18 inside the first storage column groove 12, the top of the adapter column 1803 and the bottom of the synchronous rod 206 are threadedly connected, and the adapter column 1803 is slidably connected inside the cover 17, the adjustment component 18 can be used to avoid the rigid transmission of pressure state between the synchronous rod 206 and the pressure sensor 11. In this embodiment, the pneumatic push rod 201 assembled to the top of the cover 8 controls the multi-fork drive frame 207 to move to the bottom. The pressure rod 208 pinned to one end of the multiple forks of the multi-fork drive frame 207 drives the drive arm 202 to rotate around its hinge point with the second support seat 205 and the first support seat 204. This can support the multi-fork drive frame 207 to control the multiple support arc plates 4 to retract towards the center or expand outwards. During this process, the two guide crossbars 203 slide inside a cylindrical cover 801, and the rollers 6 assembled to the bottom of the support arc plate 4 roll inside the receiving slot 5 to reduce the resistance of movement. This can tighten the textile threads or fabrics (the two ends of the textile threads or fabrics are fixed by any two of the multiple fixing components 3) that are wrapped around the outside of multiple support arc plates 4 and whose winding state is controlled by the limiting ball heads 9 of different heights. Simultaneously, while the pneumatic push rod 201 controls the multi-fork drive frame 207 to move multiple support arc plates 4 and apply pressure to the textile threads or fabric, the synchronous upright rod 206 simultaneously applies pressure to the top of the adjustment component 18. When the adjustment component 18 is under pressure, the connecting column 1803 moves inside the cover 17, driving the sliding plate 1801 to apply pressure to the movable pressure plate 1802 inside the first storage column groove 12 using multiple second springs 1805. The support pressure sensor 11 obtains pressure data, and in conjunction with existing fiber tensile strength judgment technology, the tensile strength data of the textile can be obtained.

[0022] Example 2: Based on Example 1, this example describes a specific structure for fixing the ends of textile threads or fabrics, such as... Figures 3 to 6 As shown, the fixing component 3 includes a U-shaped frame 301, a bracket 303 is provided on the inner side of the U-shaped frame 301, and limit pins 302 are pin-connected to both sides of the bottom of the U-shaped frame 301. A support rod 304 is welded to the center of the bottom of the bracket 303, and a first spring 305 is sleeved to the outside of the support rod 304. The bracket 303 is located at the top of the cover 8, and the first spring 305 is supported between the top of the cover 8 and the bottom of the bracket 303. By pinning the limiting pin 302 to the inside of the multi-fork drive frame 207, when the pneumatic push rod 201 controls the multi-fork drive frame 207 to drive multiple pressure rods 208 to the corresponding positions inside the strip groove 16 of the drive arm 202, on the one hand, multiple support arc plates 4 can be controlled to expand outward to tighten the textile threads or fabrics, and on the other hand, the U-shaped frame 301 can be slidably connected to the inside of the column cover 801, and the support upright 304 can be slidably connected to the inside of the column cover 801, compressing the first spring 305 between the cover 8 and the bracket 303, further clamping the ends of the textile threads or fabrics between the U-shaped frame 301 and the bracket 303. Secondly, to prevent the textile threads or fabric from slipping at the clamped end due to the outward expansion and tension of the multiple supporting arc plates 4 when they are clamped between the bracket 303 and the U-shaped frame 301, such as... Figure 6 As shown, multiple anti-slip ribs 306 are provided on the top inner wall of the U-shaped frame 301 and the top surface of the bracket 303. By staggering the multiple anti-slip ribs 306 on the U-shaped frame 301 and the multiple anti-slip ribs 306 on the bracket 303, when the ends of textile threads or fabrics are clamped between the U-shaped frame 301 and the bracket 303, the multiple anti-slip ribs 306 can apply pressure to the ends of textile threads or fabrics to increase friction, thus ensuring the effective clamping of the ends of textile threads or fabrics.

[0023] In this embodiment, by controlling the bracket 303 to drive the support rod 304 to move downward inside the cover 8, the first spring 305 sleeved on the outside of the support rod 304 is compressed, and the textile thread or cloth is wrapped around the outside of multiple support arc plates 4. The winding height is controlled by the limiting ball head 9 on the surface of the guide arc plate 13. The end is between two adjacent support arc plates 4, passes through the surface of the guide arc plate 13 and between the U-shaped frame 301 and the bracket 303. After the bracket 303 is released, the end is clamped and fixed by the anti-slip ribs 306 interlaced on the U-shaped frame 301 and the bracket 303. Meanwhile, when the pneumatic push rod 201 controls the multi-fork drive frame 207 to drive multiple pressure rods 208 inside the strip groove 16 of the drive arm 202 at the corresponding position, on the one hand, it controls multiple support arc plates 4 to expand outward, tightening the textile threads or fabrics, and on the other hand, it causes the U-shaped frame 301 to slide inside the cylindrical cover 801, and causes the support upright 304 to slide inside the cylindrical cover 801, compressing the first spring 305 between the protective cover 8 and the bracket 303, further clamping the ends of the textile threads or fabrics between the U-shaped frame 301 and the bracket 303.

[0024] Specifically, during the tensile strength test of textile threads or fabrics using this device; First, the control bracket 303 drives the support rod 304 to move downward inside the cover 8, so as to compress the first spring 305 sleeved on the outside of the support rod 304, and wrap the textile threads or fabric around the outside of multiple support arc plates 4. The winding height is controlled by the limiting ball head 9 on the surface of the guide arc plate 13, so as to control the winding state of the textile threads or fabric. The end is located between two adjacent support arc plates 4, and passes through the surface of the guide arc plate 13 between the U-shaped frame 301 and the bracket 303, so that the end of the textile thread or fabric is clamped and fixed. Subsequently, the pneumatic push rod 201 controls the multi-fork drive frame 207 to move to the bottom and is pinned to the pressure rod 208 inside one end of the multiple forks of the multi-fork drive frame 207. At the corresponding position, the drive arm 202 moves inside the strip groove 16, causing the drive arm 202 to rotate around its hinge point with the second support seat 205 and the first support seat 204. This can support the multi-fork drive frame 207 to control the multiple support arc plates 4 to retract towards the center or expand outwards. During this process, two guide crossbars 203 slide inside a cylindrical cover 801, and rollers 6 assembled to the bottom of the support arc plate 4 roll inside the receiving slot 5. Next, as the pneumatic push rod 201 controls the multi-fork drive frame 207 to move multiple support arc plates 4 and apply pressure to the textile threads or fabric, the synchronous upright rod 206 simultaneously applies pressure to the top of the adjustment component 18. When the adjustment component 18 is under pressure, the connecting column 1803 moves inside the cover 17, driving the sliding plate 1801 to apply pressure to the movable pressure plate 1802 inside the first storage column groove 12 using multiple second springs 1805, so that the pressure data is transmitted to the pressure sensor 11. During this process, the U-shaped frame 301 slides inside the cylindrical cover 801, and the support rod 304 slides inside the cylindrical cover 801, compressing the first spring 305 between the cover 8 and the bracket 303, further clamping the textile thread end or fabric between the U-shaped frame 301 and the bracket 303, so as to prevent the textile thread or fabric from sliding due to the influence of the multiple support arc plates 4 expanding outward and tightening the textile thread or fabric when it is clamped between the bracket 303 and the U-shaped frame 301.

[0025] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
