[0002] Textile materials are commonly used in decorative materials, including chemical fiber carpets, non-woven wall coverings, linen, nylon, colored tape, flannel and other fabrics. In order to understand the performance of textile materials, the tearing strength of fabrics is usually tested. The existing technology uses a mechanical structure to stretch the material (such as fabric) multiple times to test its tearing resistance;

[0003] The existing tensile testing device also requires the tester to prepare the fabric for testing in advance. However, during the random inspection process, this method requires a lot of time to prepare and requires additional tools, which makes the testing inconvenient. Therefore, we need to make improvements to this. Summary of the invention

[0004] The purpose of the present invention is to solve the problems existing in the background technology and to propose a detection device for the tensile properties of textiles.

[0005] To achieve the above objectives, the present invention discloses a device for detecting the tensile properties of textiles, comprising a base, wherein feet are fixedly installed at the bottom corners of the base, the upper surface of the base is connected to a U-shaped frame via a fixedly connected support column, a fixing plate is fixedly connected to the front end of one side of the U-shaped frame, a cloth-repelling piece is arranged on the upper inner side of the fixing plate, a scale marking piece is arranged on the outer side of the cloth-repelling piece, a human-shaped frame is fixedly installed on the upper inner side of the U-shaped frame, a bracket is connected to the front end of one side of the human-shaped frame via a stretching assembly, cloth-moving assemblies are arranged at both ends of the bottom of the bracket, a bottom plate is fixedly installed on the outer side of one end of the U-shaped frame away from the fixing plate, grooves are opened on both sides of the upper surface of the bottom plate, rotating rods are fixedly installed inside both sides of the U-shaped frame and above the bottom plate, and threaded rings are threadedly connected to one end of the two rotating rods.

[0006] Preferably, the cloth-retaining member comprises a retaining rod fixedly mounted on the upper inner side of the fixing plate, and a clamping rod is fixedly mounted on one end of the retaining rod.

[0007] Preferably, the scale marking member comprises sliding rods which are respectively installed obliquely on the outside of both sides of the clamping rod, and the outer surfaces of the sliding rods are affixed with scale stickers.

[0008] Preferably, the stretching assembly comprises a hydraulic cylinder fixedly mounted on the inner top wall of the human-shaped frame, and the telescopic end of the hydraulic cylinder is connected to the upper surface of the bracket.

[0010] Preferably, the negative pressure assembly includes an L-shaped block fixedly mounted on one side of the moving seat, a negative pressure vacuum pump is fixedly mounted on the upper surface of the L-shaped block, a suction cup is installed on the port of the negative pressure vacuum pump, a cutter is fixedly mounted on the bottom of the moving seat, and a plurality of ball bearings are installed on the bottom edge of the suction cup.

[0011] Preferably, the reciprocating member includes a support plate fixedly mounted on the upper surface of the sliding seat, a cylinder is provided at one end of the support plate, a telescopic end of the cylinder is fixedly connected to the outer wall of the support plate, and the cylinder is provided on the inner side of one end of the sliding seat.

[0012] Preferably, clamping seats are fixedly installed at both ends of the bottom of the bracket, and grooves are provided on the surfaces of the two clamping seats on one side close to each other, bolts are threadedly inserted into the inner sides of the two clamping seats, and clamping plates are rotatably mounted on the ends of the bolts away from the clamping seats, and fixing blocks are fixedly installed at both ends of one side of the bracket, and connecting rods are correspondingly installed on the inner sides of the two fixing blocks through rotatably installed rotating shafts, and the end of the connecting rod away from the rotating shaft is connected to a slider through a rotatably installed plug shaft, and the slider slides on the outside of the sliding rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The set stretching parts can prompt the clamping seats and clamping plates on both sides of the bracket to lift the clamped fabric. After the fabric passes over the lower surface of the support rod and is fixed by the clamping seats and clamping plates at the bracket at both ends, the bracket is gradually raised to perform triangular stretching, so as to perform stretching detection on the fabric.

The hydraulic cylinder can control the height of the bracket, and the cylinder can drive the support plate and the shift seat to move back and forth, so as to cut the cloth laid on the surface of the bottom plate. In the cutting process, the ball at the bottom of the suction cup can roll and press the cloth on both sides of the cutting groove, so as to quickly cut out the test sample. After the cutting is completed, the negative pressure vacuum pump is started, so that the suction cup can transport the cut sample cloth to the lower surface of the column. Finally, the staff clamps the two ends of the cut cloth sample between the corresponding clamp seat and the clamp plate, and quickly fixes the cloth with bolts. This method can meet the rapid sampling of random inspections, so that the detection efficiency is further improved. BRIEF DESCRIPTION OF THE DRAWINGS

During the cutting movement, the ball 35 at the bottom edge of the suction cup 29 can roll on the upper surface of the bottom plate 5, thereby cooperating with the cutter 34 to roll and press, and the cutting is completed. After the cutting, the fabric is adsorbed on the bottom of the suction cup 29 by the negative pressure vacuum pump 28, and then the cylinder 10 transports the fabric to the lower end of the support rod 21. Then the staff puts one end of the fabric between the clamp seat 20 and the clamp plate 19, and then rotates the bolt 17 to allow the clamp plate 19 to clamp the fabric on one side of the clamp seat 20. Then the hydraulic cylinder 11 lifts the bracket 15 to stretch the fabric toward both ends. During the stretching process, the slider 22 moves to the outside of the slide bar 6, and the lower edge of the slider 22 corresponds to the value of the scale sticker 14 on the outside of the slide bar 6, so that the stretch value of the fabric can be detected, and then the stretch test results of the sample are detected by an external computer program.
