Description

Technical Field

[0001] The invention belongs to the technical field of cloth testing equipment, and in particular relates to a novel textile fabric tensile strength testing device. Background Art

[0002] Testing the tensile strength of textile fabrics is a key test for assessing their quality and durability. This test applies axial tension to a textile sample using a tensile testing machine until it breaks. The test then measures the maximum load (typically expressed in N or cN / tex) and elongation at break, quantifying the material's tensile properties. The results directly influence the design and selection of clothing, home textiles, and industrial fabrics. High-strength fabrics are often used in outdoor equipment and safety protection applications. Testing can help manufacturers optimize fiber formulations and weaving processes to ensure their products meet performance requirements.

[0003] A Chinese patent application with publication number CN206387665U discloses a device for detecting the tensile strength of textile fabrics. The device uses a long and flat slit to fix the fabric so that the fabric is evenly stressed, which can effectively detect the tensile strength of the fabric and reduce detection errors. At the same time, the device uses a continuously variable speed motor and a moving screw rod to evenly apply tension, making the test results more accurate. This solves the problem of large detection errors in current fabric tensile strength detection devices, such as ordinary tensile gauges and tensile detection devices, due to uneven force.

[0004] However, the above device still has the following problems during implementation:

[0005] After clamping both sides of the fabric with two sets of plywood, the mobile clamp is driven by an electric motor and a spiral sleeve to move. By applying pressure until the fabric is torn, the tensile strength of the fabric can be tested. However, only the force test in the horizontal direction can be performed. The fabric is subjected to less horizontal pulling during use, and the sides are often subjected to greater tension. Once the side of the fabric breaks, the fabric will tear instantly. Therefore, the side strength test of the fabric is particularly important.

[0006] To this end, we provide a new type of textile fabric tensile strength testing device to solve the above problems. Summary of the Invention

[0007] The purpose of the present invention is to provide a new type of textile fabric tensile strength detection device. Through the cooperation of an adjustment component, a clamping component, a drive component and a linkage component, the present invention solves the problem that the tensile strength detection device of the fabric in the prior art lacks a side force detection function and the detection data of the fabric is not accurate enough.

The side of the fabric is stretched and detected through the adjusting component. A clamping component is arranged on the top of the base. The clamping component includes a hydraulic rod installed on the top of the rotating frame and a clamping plate installed at the output end of the bottom of the hydraulic rod. The two sides of the fabric are clamped through the clamping component. A driving component is arranged on the top of the base to provide power for stretching the fabric. A linkage component is arranged on the top of the base. The linkage component includes an adjusting plate installed behind the pressing block, an adjusting groove opened inside the adjusting plate, and a moving shaft slidably connected inside the adjusting groove to provide power for the side stretching detection of the fabric.

[0010] The present invention is further configured such that the driving component includes a driving motor arranged on the top of the base, a screw rod installed at the output end of the driving motor, and a moving sleeve threadedly connected to the surface of the screw rod, which converts the rotational motion into an axial motion by the action of the thread.

[0011] The present invention is further configured such that the surface of the moving sleeve is fixedly connected to the pressing block. A support column is fixedly connected to one side of the first pressure sensor, and the other side of the support column penetrates through the push plate and is fixedly connected to the moving seat. The clamping plate is slidably connected to the inner wall of the rotating frame for respectively fixing the two sides of the fabric.

[0012] The present invention is further configured such that the surface of the driving motor is fixedly connected to a support frame, and a vertical column is fixedly connected to the bottom of the support frame. The bottom of the vertical column is fixedly connected to the base to provide a supporting effect for the driving motor and the pressing block.

[0013] The present invention is further configured such that the linkage component further includes a guide rod installed behind the toothed plate, a moving frame slidably connected to the surface of the guide rod, a support shell installed on the top of the moving frame, a second pressure sensor installed inside the support shell, and a pushing frame installed in front of the second pressure sensor to provide detection data for the side pulling of the fabric.

[0014] The present invention is further configured such that the other end of the pushing frame penetrates through the support shell and is fixedly connected to the moving shaft. A sliding groove is opened inside the moving frame to provide a supporting effect for the horizontal movement of the two toothed plates.

[0015] The present invention is further configured such that a support sleeve is sleeved on the surface of the support frame, and the bottom of the support sleeve is fixedly connected to the support shell, which is used to provide support for the front-back movement of the support shell.

[0016] The present invention is further configured such that a guide rail plate is fixedly connected to one side of the toothed plate, a vertical plate is slidably connected to the surface of the guide rail plate, and one side of the vertical plate is fixedly connected to the moving seat, which is used to maintain the meshing of the toothed plate and the gear.

[0018] The present invention is further configured such that a cross bar is fixedly connected to the top of the adjusting plate, and the top of the cross bar penetrates through the support frame, which is used to provide a limiting effect on the up-down movement of the pressing block.

[0019] The present invention has the following beneficial effects.

[0020] 1. Through the cooperation of the rotating shaft, gear and toothed plate of the adjusting assembly and the hydraulic rod and clamping plate of the clamping assembly, the present invention realizes the precise clamping and sector-shaped stretching of the side edge of the fabric, solves the defect that the traditional device can only perform horizontal tensile force detection. The adjusting plate, adjusting groove and moving shaft of the linkage assembly are driven by the screw rod and moving sleeve of the driving assembly, so that the fabric generates sector-shaped deformation under the action of lateral tensile force. Combined with the dual monitoring of the first pressure sensor and the second pressure sensor, the tensile strength of the side edge of the fabric can be more comprehensively evaluated, significantly improving the accuracy of the detection data, especially suitable for the test of high-strength fabrics that are prone to tearing on the side edge.

[0021] 2. Through the linkage structure of the pressing block and the push plate, combined with the rigid connection of the support column and the moving seat, the present invention ensures the uniform transmission of force during the horizontal stretching process, avoids errors caused by local stress concentration. The guiding and reset design of the support sleeve and the reset rod, combined with the meshing maintaining mechanism of the guide rail plate and the vertical plate, enables the device to still operate stably during high-frequency tests, extending the service life, and the limiting effect of the cross bar on the pressing block further improves the movement accuracy. The overall structure is compact and efficient, with the characteristics of fast dynamic response and simple operation, which can meet the requirements of industrial batch detection and effectively optimize the process quality control process of textile fabrics.

The rotational motion is converted into axial motion by the action of the thread.

[0042] Embodiment 3

[0043] Please refer to Figures 1-10, on the basis of Embodiment 1 and Embodiment 2, the other end of the pushing frame 808 penetrates through the support shell 806 and is fixedly connected to the moving shaft 803. A chute 12 is provided inside the moving frame 805 to provide support for the horizontal movement of the two sets of toothed plates 505. A support sleeve 13 is sleeved on the surface of the support frame 10, and the bottom of the support sleeve 13 is fixedly connected to the support shell 806 to provide support for the forward and backward movement of the support shell 806. A guide rail plate 14 is fixedly connected to one side of the toothed plate 505, and a vertical plate 15 is slidably connected to the surface of the guide rail plate 14. One side of the vertical plate 15 is fixedly connected to the moving seat 501 to keep the toothed plate 505 and the gear 504 engaged.

The top of the adjusting plate 801 is fixedly connected to a cross bar 20, and the top of the cross bar 20 penetrates through the support frame 10 to provide a limiting effect on the up and down movement of the pressing block 2.

[0044] Specifically: both sets of guide rods 804 are slidably connected to the chute 12 inside the moving frame 805.

The cross bar 20 is used to provide a limiting effect on the up and down movement of the pressing block 2.

[0045] The working principle of the present invention is as follows: The staff moves the fabric to be detected, inserts the two sides of the fabric into the two sets of rotating frames 503 respectively, and flattens the fabric. Then, the hydraulic rod 601 is started through an external controller. The hydraulic rod 601 drives the clamping plate 602 to move, and the clamping plate 602 moves to clamp and fix the two sides of the fabric. Then, the driving motor 701 is started. The driving motor 701 cooperates with the screw rod 702 to drive the moving sleeve 703 to move downward. The moving sleeve 703 drives the pressing block 2 to move downward. The pressing block 2 pushes the two push plates 3 to move in opposite directions. The push plates 3 cooperate with the first pressure sensor 4 and the support column 9 to drive the moving seat 501 to move. The moving seat 501 drives the rotating frame 503 to move. The two rotating frames 503 move in opposite directions to pull the fabric in the horizontal direction, so that the fabric bears uniform tension. Through the pressure value fed back by the first pressure sensor 4, the horizontal pressure received when the fabric breaks can be detected.

[0046] When it is necessary to detect the side tensile force of the fabric, the hydraulic rod 601 can be activated to clamp both sides of the fabric. At this time, the drive motor 701 is activated again to drive the pressing block 2 to move upward. The pressing block 2 drives the adjusting plate 801 to move. The adjusting plate 801 cooperates with the adjusting groove 802 to push the moving shaft 803 to move. The moving shaft 803 cooperates with the pushing frame 808 to drive the second pressure sensor 807 to move. The second pressure sensor 807 cooperates with the support shell 806 to drive the moving frame 805 to move. The moving frame 805 cooperates with the guide rod 804 to drive the toothed plate 505 to move. The toothed plate 505 cooperates with the gear 504 to drive the rotating shaft 502 to rotate. The rotating shaft 502 cooperates with the rotating frame 503 to drive the fabric to rotate. As Figure 10 shown, the fabric is pulled in a side fan shape. Through the pressure value feedback by the first pressure sensor 4, the side pressure suffered by the fabric during fracture can be detected, improving the accuracy of the fabric detection data.

Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways.
