Description

Technical Field

[0001] The utility model relates to the technical field of clothing fabric detection, and more specifically, to a tensile strength testing device for clothing fabrics. Background Art

[0002] Fabric strength testing refers to the testing of textile fabrics to evaluate their strength and durability. The testing items cover a wide range, including tensile, tearing, yarn strength, elongation, interlacing resistance, morphological structure, raw yarn strength, warp and weft density, yarn fineness, post-finishing process, fiber strength, etc. Among them, the most common testing item should be the tensile resistance test.

[0003] In the prior art, a patent document with the publication number CN117571478A discloses a fabric tensile resistance testing device, which includes a frame, a placement component for fixing the fabric to be tested, and a driving component for tensile testing of the fabric. The placement component includes: a horizontal rail Ⅰ installed on the frame, a right-angle mounting frame arranged on the horizontal rail Ⅰ; and a clamping roller rotatably connected to the right-angle mounting frame for fixing the fabric. The driving component includes: two vertical rails symmetrically arranged on the horizontal rail Ⅰ; a lead screw connecting the two vertical rails in series and capable of rotating between the two vertical rails, a reduction motor installed on the frame and having an output shaft connected to the lead screw, and a sliding sleeve connected to the lead screw by a thread. Through the settings of the placement component and the driving component, the fabric can be quickly fixed by using two rotatable clamping rollers. Then, the reduction motor drives the lead screw to rotate, and under the action of the sliding sleeve, the driving block and the slidable right-angle mounting frame slide synchronously, so that the distance between the two clamping rollers becomes farther to pull the fabric, thereby completing the tensile resistance test of the fabric. However, the above device can often only automatically complete a single test of the clothing fabric during detection and cannot achieve automatic sectional repeated detection of the clothing fabric. Therefore, the detection accuracy and precision are relatively limited. Based on this, the utility model provides a tensile strength testing device for clothing fabrics to solve the technical problems raised in the above background art. Content of the Utility Model

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a tensile strength testing device for clothing fabrics. When the utility model works, it can automatically complete the sectional repeated continuous detection of the clothing fabric. By realizing the automatic sectional repeated continuous detection function, the testing accuracy during the tensile strength test of the clothing fabric is effectively improved.

[0005] To achieve the above object, the present utility model provides the following technical solutions: A tensile strength testing device for clothing fabrics, comprising a frame, on which a winding roller driven by a worm motor is rotatably connected, and the winding roller is wound with a fabric to be tested. Two symmetrically arranged linear drive modules are installed on the frame, and a detection frame is drivingly connected to each of the two linear drive modules. A cloth clamping member is installed on each detection frame, and a pressing member for pressing the fabric to be tested is installed on the frame.

[0006] As a preferred technical solution of the present utility model, the cloth clamping member includes a clamping screw rod vertically arranged and rotatably connected to the detection frame. A motor is installed on the detection frame, and the output shaft end of the motor is fixedly connected to the clamping screw rod. A positive thread section and a reverse thread section are symmetrically arranged on the clamping screw rod, and a clamp is drivingly connected to each of the positive thread section and the reverse thread section. The two clamps are arranged in a mirror image, and a clamping gap for clamping the fabric to be tested is fixedly arranged between the two clamps.

[0007] As a preferred technical solution of the present utility model, the pressing member includes a pressing push rod fixed to the frame and vertically arranged. The bottom end of the pressing push rod is fixedly installed with a main pressing frame, and a measuring pressing plate is arranged on the bottom surface of the main pressing frame. A group of pressure sensors are installed between the main pressing frame and the measuring pressing plate, and a single-chip microcomputer electrically connected to the pressure sensors is fixedly installed on the frame.

[0008] As a preferred technical solution of the present utility model, a waste storage box with an open top is movably installed on the frame.

[0009] As a preferred technical solution of the present utility model, the linear drive module includes a drive motor fixed to the frame and a drive screw rod rotatably connected to the frame. The output shaft end of the drive motor is fixedly connected to the drive screw rod. The drive screw rod is drivingly connected to the detection frame at the corresponding position, and the detection frame is slidably connected to the frame. The axis of the drive screw rod is parallel to the horizontal plane.

[0010] As a preferred technical solution of the present utility model, the unwinding direction of the fabric to be tested is parallel to the axis of the drive screw rod.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. When the present utility model works, it can automatically complete the segmented and repeated continuous detection of clothing fabrics. By realizing the function of automatic segmented and repeated continuous detection, the test accuracy during the tensile strength test of clothing fabrics can be effectively improved.

[0013] 2. When the present utility model is in use, the fabric to be tested is wound around the roller. In the initial detection mode, the two detection frames are arranged in a staggered manner. When the two detection frames are arranged in a staggered manner, the two detection frames are respectively arranged on both sides of the pressure application push rod. During the first detection, the fabric to be tested is clamped by the clamps on the two detection frames. After the fabric is clamped by the two detection frames, it maintains a set tension between the two detection frames. Subsequently, the pressure application push rod gradually applies pressure to the fabric to be tested. When the fabric to be tested breaks, the peak value of the pressure sensor is recorded, and then the tensile strength of the fabric to be tested is measured.

[0014] 3. When the present utility model conducts repeated detection, the clamp originally on the rightmost side clamps the broken waste cloth above the waste material storage box, and enables the broken waste cloth to fall into the waste material storage box. After the waste cloth is separated, the originally rightmost detection frame moves to the symmetric position of the originally leftmost detection frame, and the originally leftmost clamp drives the fabric to move to the position of the originally rightmost clamp. After the positions of the two detection frames are switched, the clamp clamps the fabric, and the pressure application push rod can conduct repeated pressure application detection on a new section of the fabric to be tested. By obtaining multiple groups of detection data, the accurate tensile strength of the clothing fabric can be obtained. Description of the Drawings

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0021] As shown Figures 1 to 4 in the figure, the utility model provides a tensile strength testing device for clothing fabrics, which includes a frame 1. A winding roller 3 driven by a worm motor 2 is rotatably connected to the frame 1, and a fabric 4 to be tested is wound around the winding roller 3;

[0022] Two symmetrically arranged linear drive modules 5 are installed on the frame 1, and a detection frame 6 is drivingly connected to each of the two linear drive modules 5;

[0023] The linear drive module 5 includes a drive motor fixed to the frame 1 and a drive lead screw rotatably connected to the frame 1. The output shaft end of the drive motor is fixedly connected to the drive lead screw. The drive lead screw is drivingly connected to the detection frame 6 at the corresponding position. The detection frame 6 is slidably connected to the frame 1, and the axis of the drive lead screw is parallel to the horizontal plane;

[0024] The unwinding direction of the fabric 4 to be tested is parallel to the axis of the drive lead screw;

[0025] A cloth clamping member is installed on each detection frame 6, and a pressing member for pressing the fabric 4 to be tested is installed on the frame 1.

[0026] The cloth clamping member includes a clamping lead screw 7 vertically arranged and rotatably connected to the detection frame 6. A motor 8 is installed on the detection frame 6. The output shaft end of the motor 8 is fixedly connected to the clamping lead screw 7. A positive thread section and a reverse thread section are symmetrically arranged on the clamping lead screw 7. Clamps 9 are drivingly connected to both the positive thread section and the reverse thread section. The two clamps 9 are arranged in a mirror image. A slit for clamping the fabric 4 to be tested is fixedly arranged between the two clamps 9;

[0027] During operation, through the setting of the positive thread section and the reverse thread section, the two clamps 9 can be driven to approach or move away from each other synchronously. By changing the distance between the two clamps 9, the clamping state of the two clamps 9 on the fabric 4 to be tested is changed.

[0028] The pressing member includes a pressing push rod 10 vertically arranged and fixed to the frame 1. A driving pressing frame 11 is fixedly installed at the bottom end of the pressing push rod 10. A measuring pressing plate 12 is arranged on the bottom surface of the driving pressing frame 11. A group of pressure sensors 13 are installed between the driving pressing frame 11 and the measuring pressing plate 12. A single-chip microcomputer 14 electrically connected to the pressure sensors 13 is fixedly installed on the frame 1.

[0029] When testing the tensile strength of the fabric, the pressure sensors 13 first perform self-zero calibration. After the zero calibration is completed, the pressing push rod 10 applies pressure upward. After the pressing push rod 10 applies pressure downward, the measuring pressing plate 12 contacts the fabric 4 to be tested, and then gradually applies pressure to the fabric 4 to be tested;

[0030] A waste storage box 15 with an open top is movably installed on the frame 1. During use, the waste storage box 15 is used to receive the broken waste cloth after detection.

[0031] Working principle and usage process of the present utility model:

[0032] During use, the fabric 4 to be tested is wound around the roller 3. In the initial detection mode, the two inspection frames 6 are arranged in a staggered manner. When the two inspection frames 6 are arranged in a staggered manner, the two inspection frames 6 are respectively arranged on both sides of the pressure push rod 10. During the first detection, the fabric 4 to be tested is clamped by the clamps 9 on the two inspection frames 6. After the fabric is clamped by the two inspection frames 6, it maintains a set tension between the two inspection frames 6. Subsequently, the pressure push rod 10 gradually applies pressure to the fabric 4 to be tested. When the fabric 4 to be tested breaks, the peak value of the pressure sensor 13 is recorded, and then the tensile strength of the fabric 4 to be tested is measured;

[0033] Thereafter, repeated detection can be carried out;

[0034] During repeated detection, the clamp 9 originally on the rightmost side clamps the broken waste cloth above the waste storage box 15, and enables the broken waste cloth to fall into the waste storage box 15. After the waste cloth is separated, the originally rightmost inspection frame 6 moves to the symmetric position of the originally leftmost inspection frame 6. The originally leftmost clamp 9 drives the fabric to move to the position of the originally rightmost clamp 9. After the positions of the two inspection frames 6 are switched, the clamp 9 tightly clamps the fabric, and the pressure push rod 10 can perform repeated pressure detection on a new section of the fabric 4 to be tested;

[0035] By obtaining multiple groups of detection data, the accurate tensile strength of the clothing fabric can be obtained;
