Description

Technical Field

[0001] The invention relates to the technical field of textile flat yarn testing, in particular to a textile flat yarn tensile testing device. Background Art

[0002] Flat wire is a chemical fiber monofilament with a flat cross section. It is also called cutting fiber in the plastic weaving industry. It is the basic material for producing plastic woven fabrics. Flat wire is made of a specific variety of polypropylene and polyethylene resin through melt extrusion into a film, and then cut into strips longitudinally. The strips are heated, stretched and oriented at the same time to shape them, and finally wound into flat wire spindles. Flat wire is used to make carpets, packaging bags, ropes, fishing nets, belt bases, coarse sewing threads, artificial turf, building reinforcement materials, door curtains, handicrafts, etc.; it can also be cut into short fibers to make pure or blended fabrics.

[0003] Before the tensile test of the flat wire, it is necessary to fix the two ends of the flat wire, and then use external tension to pull one end of the flat wire until the flat wire is broken to obtain the tensile value of the flat wire.

[0004] However, in the prior art, after placing the traditional equipment on the desktop, it has no fixed structure, which will cause the equipment to be easily impacted by the outside world during the flat wire pulling test, resulting in poor test accuracy. At the same time, the pulling force value cannot be intuitively viewed and analyzed before the flat wire is broken, resulting in the inability to analyze the changing state of the flat wire according to the pulling force during the flat wire pulling test. Summary of the invention

[0005] The purpose of the present invention is to solve the following shortcomings in the prior art. In the prior art, after the traditional equipment is placed on the desktop, it has no fixed structure, which will cause the equipment to be easily affected by external collisions during the flat wire pulling test, resulting in poor test accuracy. At the same time, the tension value cannot be intuitively viewed and analyzed before the flat wire is broken, resulting in the inability to analyze the changing state of the flat wire according to the tension during the flat wire pulling test. A textile flat wire tension test device is proposed.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A textile flat yarn tensile testing device comprises a display and a mounting frame, wherein the mounting frame is fixedly connected to the upper surface of the display, and a display screen is mounted on the inclined surface of the display;

[0008] Two mounting blocks are installed on the mounting frame, and the two mounting blocks are respectively clamped and fixed, and the clamping components include a fixed block, a clamping plate, a pushing block, a hinged plate, a flip plate, and a sliding block, the fixed block is fixedly connected to the mounting block, one end of the fixed block is circularly arranged, the pushing block is slidably connected to the mounting block and is located on one side of the fixed block, the clamping plate is fixedly connected to a side wall of the pushing block close to the fixed block, one end of the hinged plate is hinged on a side of the pushing block away from the mounting block, one end of the flip plate is rotatably connected to the fixed block, a sliding groove is provided on the flip plate, one end of the sliding block is slidably connected in the sliding groove, and one end of the hinged plate away from the pushing block is hinged on the sliding block;

[0009] Suction components are installed on both sides of the lower end of the display, and the suction components include an air collecting cavity, a suction cup, and a docking cavity. The two air collecting cavities are fixedly connected to both sides of the display, and the multiple suction cups are fixedly connected to the air collecting cavities, and the docking cavity is fixedly connected between the two air collecting cavities.

[0010] Preferably, the clamping component further comprises a scale, and the scale is fixedly connected to one of the side walls of the mounting frame.

[0011] Preferably, the suction component also includes a piston plate, a pull rod, a square cavity, and an air supply cavity. The square cavity is fixedly connected to the mounting block, the piston plate is slidably connected in the square cavity, the pull rod is fixedly connected to the piston plate and the push block, and the air supply cavity is fixedly connected between the square cavity and one of the air collecting cavities.

[0012] Preferably, the side walls of the two mounting blocks are rotatably connected with screw rods respectively, one end of the screw rod away from the mounting block is fixedly connected with a disc, and a rack is provided on the outer surface of the disc.

[0013] Preferably, a screw cap is threadedly connected to the outer surface of the screw rod, and one side wall of the screw cap is fixedly connected to an L-shaped plate.

[0014] Preferably, one end of the flip plate away from the push block is hinged to a connecting plate, and one end of the connecting plate away from the flip plate is hinged to the L-shaped plate.

At this time, the two flip plates can pull the push block to move in the direction of the fixed block through the slider and the hinged plate. When the push block moves to fit the side wall of the fixed block, the clamping plate is in the groove of the fixed block and completes the extrusion and fixation of the flat wire wrapped around the upper end of the fixed block, thereby achieving the effect of quickly fixing the flat wire before the tensile test.

[0020] As the push block on the lower side moves toward the fixed block, the push block can pull the pull rod to move, and the pull rod can pull the piston plate to slide in the square cavity. The square cavity and the two air collecting cavities are both under negative pressure, and the suction cup is connected to the air collecting cavity, so that the suction cup can be firmly adsorbed on the desktop, thereby fixing the monitor and preventing the monitor from shifting during the experiment.

One end of the hinged plate 12 is hinged to the side of the push block 11 away from the mounting block 5. One end of the flip plate 13 is rotatably connected to the fixed block 6. A slide groove is provided on the flip plate 13. One end of the slider 14 is slidably connected in the slide groove. The length of the slide groove is limited.
