[0002] Material quality testing of underwear fabrics usually includes composition testing, physical properties testing, dimensional stability testing, color fastness testing, moisture absorption and breathability testing, and antibacterial performance testing. The physical properties test is to test the physical properties of underwear fabrics, such as tensile strength, tear strength, wear durability, fabric density, etc. These tests can evaluate the strength, durability and quality characteristics of the fabric to ensure its performance in wearing, washing and daily use. The tensile strength test of underwear fabrics is an important part of it. A tensile testing machine is required when conducting a tensile strength test on underwear fabrics.

[0003] Most of the existing fabric tensile testing machines only use upper and lower clamps for strength stretching. Underwear fabrics are usually subjected to lateral tensile force when worn, and using only upper and lower clamps for strength stretching cannot accurately simulate this situation. Therefore, relying solely on the tensile test of the upper and lower clamps may not fully reflect the performance of underwear fabrics in actual use, which will reduce the accuracy of the test results.

[0004] Therefore, we propose a material quality testing instrument for underwear fabric production to solve the above problems. Utility Model Content

[0012] As a preferred material quality detection instrument for underwear fabric production of the utility model, a limiting groove is provided on one opposite side of the bidirectional screw rod, the bottom of the limiting groove is fixedly connected to the bottom of the positioning sleeve, and the limiting groove is slidably connected to one end of the movable sleeve.

[0015] 1. The utility model adjusts the spacing between the movable sleeve and the positioning sleeve according to the width of the fabric to be tested. The staff can start the power motor, and the power motor starts to drive the bidirectional screw to rotate along the mounting plate. When the bidirectional screw rotates, the two movable sleeves can be driven to rotate along the surface of the bidirectional screw. The two movable sleeves are moved away from each other along the surface of the bidirectional screw through the cooperation of the limit groove and the movable sleeve until the spacing between the two movable sleeves is adjusted to the width of the fabric to be tested.

When the lifting block moves upward, the top of the fabric to be tested is pulled upward by the cooperation of the moving sleeve and the clamp. The moving sleeve and the clamp set on the top of the base can stretch the bottom of the fabric. Through simultaneous action, the fabric to be tested can be subjected to a tensile test. During the test, the tensile tester gradually applies tensile force to the fabric to be tested until the fabric breaks or reaches the preset tensile limit. The tensile tester automatically records the tensile force and displacement data. Ensure that various data during the test process are accurately recorded, including the maximum tensile force value, fracture displacement, etc. The staff calculates and analyzes the tensile strength indicators of the fabric, such as the maximum tensile force, fracture strength and elongation, based on the test data.

[0024] See also Figure 1-Figure 6 , a material quality testing instrument for underwear fabric production, comprising:

[0025] The tensile testing machine 1 comprises a frame 101, a base 102 is fixedly connected to the bottom of the frame 101, a positioning plate 105 is arranged inside the frame 101, a threaded rod 104 is threadedly connected to the positioning plate 105, and a lifting block 106 which is slidably connected to the positioning plate 105 is threadedly connected to the surface of the threaded rod 104;

The mounting plates 201 are rotatably connected to the opposite side with a bidirectional screw rod 202. One end of the bidirectional screw rod 202 is fixedly connected to the output end of the power motor 203. The center of the surface of the bidirectional screw rod 202 is threadedly connected to a positioning sleeve 211. The surfaces of the left and right sides of the bidirectional screw rod 202 are threadedly connected to movable sleeves 204. The movable sleeve 204 and the positioning sleeve 211 are fixedly connected to the opposite side with a clamp 205.

[0027] A guide rod 103 is fixedly connected inside the frame 101 , a guide sleeve is fixedly connected to the positioning plate 105 , and the guide sleeve is slidably connected to the guide rod 103 .

[0028] The bottom of the threaded rod 104 is rotatably connected to the top of the base 102 , and the top of the threaded rod 104 extends to the top of the frame 101 and is fixedly connected to a driven sprocket 107 .

[0029] A lifting motor 108 is fixedly connected to the rear side of the frame 101 , a driving sprocket 109 is fixedly connected to the output end of the lifting motor 108 , and a chain 110 is transmission-connected between the driving sprocket 109 and the driven sprocket 107 .

[0031] A limiting groove is provided on one opposite side of the bidirectional screw rod 202 , the bottom of the limiting groove is fixedly connected to the bottom of the positioning sleeve 211 , and the limiting groove is slidably connected to one end of the moving sleeve 204 .

[0032] The clamp 205 includes a base 206, at both ends of the base 206 are rotatably connected with a clamping plate 207, the opposite side of the clamping plate 207 is rotatably connected with a connecting rod 208, an electric telescopic rod 209 is connected to the base 206, the movable end of the electric telescopic rod 209 is connected to one side of the connecting rod 208, and the opposite side of the clamping plate 207 is fixedly connected with a clamping block 210. When it is necessary to clamp the fabric, the staff can start the electric telescopic rod 209, and the electric telescopic rod 209 begins to shrink after being started. As the electric telescopic rod 209 shrinks, the two clamping plates 207 can be driven to approach each other through the connection of the connecting rod 208 until the opposite side of the clamping block 210 fits the surface of the fabric, which is convenient for effectively clamping the fabric. The set clamp 205 is convenient for adjustment according to the thickness of the fabric, which can effectively expand the scope of application of the clamp 205, thereby improving the practicality of the utility model.

[0033] During use, the staff adjusts the distance between the movable sleeve 204 and the positioning sleeve 211 according to the width of the fabric to be tested. The staff can start the power motor 203, and the power motor 203 starts to drive the bidirectional screw rod 202 to rotate along the mounting plate 201. When the bidirectional screw rod 202 rotates, it can drive the two movable sleeves 204 to rotate along the surface of the bidirectional screw rod 202. Through the cooperation of the limit groove and the movable sleeve 204, the two movable sleeves 204 are moved away from each other along the surface of the bidirectional screw rod 202 until the distance between the two movable sleeves 204 is adjusted to the width of the fabric to be tested. Then the staff first connects the center of the fabric with the clamp 205 on one side of the positioning sleeve 211, and then connects the two ends of the fabric to be tested with the clamps 205 on one side of the two movable sleeves 204, so that the clamp 205 clamps and fixes the four end points of the fabric to be tested and the center points of the upper and lower positions of the fabric, which can ensure uniform distribution of force during the tensile test.

When the driven sprocket 107 rotates, it can drive the threaded rod 104 to rotate. As the threaded rod 104 rotates, it drives the lifting block 106 to move upward along one side of the positioning plate 105. When the lifting block 106 moves upward, the top of the fabric to be tested is pulled upward by the cooperation of the movable sleeve 204 and the clamp 205. The movable sleeve 204 and the clamp 205 set on the top of the base 102 can stretch the bottom of the fabric. Through the simultaneous action, the fabric to be tested can be subjected to a tensile test. During the test, the tensile testing machine 1 will gradually apply tensile force to the fabric to be tested until the fabric breaks or reaches the preset tensile limit.
