[0021] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0022] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , an embodiment of the present invention provides a sewing thread tensile strength detection device, which includes a base plate 1, with two U-shaped fixing frames 2 fixedly connected to the top of the base plate 1, and multiple groups of clamps 16 arranged adjacent to each other in the upper and lower directions are provided between the top of the fixing frames 2 and the base plate 1, and a second electric push rod 13 is movably connected to the side of the top of the base plate 1 and close to one of the fixing frames 2, and a control component for driving the second electric push rod 13 to move is provided on the top of the base plate 1, wherein one side of the clamp 16 close to the second electric push rod 13 is fixedly connected with an L-shaped connecting plate 17, a tension sensor 18 is installed at the piston rod end of the second electric push rod 13, and a T-shaped connecting frame 19 is installed at the end opposite to the second electric push rod 13, and the connecting frame 19 is movably connected between the upper and lower adjacent connecting plates 17, wherein the clamp 16 close to the second electric push rod 13 is set as a movable connection, and the clamp 16 away from the second electric push rod 13 is set as a fixed structure.

[0023] The ends of multiple wires to be tested are sequentially fixed to the clamps 16. The second electric push rod 13 operates to drive the connecting frame 19 to the side closer to the second electric push rod 13. The movement of the connecting frame 19, after being connected with the connecting plate 17, can apply tension to the wire through the movable clamp 16. At the same time, the tension sensor 18 monitors the tensile strength of the sewing thread in real time. After the test of a single wire is completed, the first electric push rod 3 operates to push the movable clamp 16 to reset. The control component drives the first electric push rod 3 to move toward the other clamp 16. The movement of the first electric push rod 3 also drives the connecting frame 19 to move in the gap between the connecting plates 17. After the first electric push rod 3 and the connecting frame 19 are moved into place, the first electric push rod 3 can continuously apply tension to the clamp 16 through the cooperation of the connecting frame 19 and the connecting plate 17, thereby completing the tensile test of another wire. The cycle can be repeated in a simple and efficient manner to complete the tensile test of multiple wires, avoiding the problem of frequent operation of the clamp 16, effectively improving the detection efficiency of the tensile strength of the sewing thread, and having strong practicality.

[0024] Two U-shaped mounting brackets 2 are fixedly connected to the top of the base plate 1. Two first electric push rods 3 are fixedly connected to the top of each mounting bracket 2. The bottom ends of the piston rods of each of the two adjacent first electric push rods 3 are fixedly connected to the first mounting plate 4 and the fourth mounting plate 7, respectively. A second mounting plate 5 and a third mounting plate 6 are fixedly connected to the top of the base plate 1, located below the first and fourth mounting plates 7. Multiple chute slots 8 are equidistantly defined within the first and second mounting plates 4, 5. Sliders 9 are slidably connected within the chute slots 8. Clamps 16 are fixedly connected to the outsides of the slides 9, the tops of the third mounting plates 6, and the bottoms of the fourth mounting plates 7, respectively. The clamping surfaces of the clamps 16 are each provided with anti-slip textures to increase clamping force and prevent the sewing thread from slipping during inspection. The tops of the slides 9 located within the first mounting plate 4 are fixedly connected to a limit plate 10. The cylinder of the second electric push rod 13 is located on one side of the first mounting plate 4 to prevent the clamp 16 from colliding with the second electric push rod 13 when the first mounting plate 4 moves downward, driving the clamp 16.

[0025] Place the two ends of the wire to be tested on the clamp 16 located below, and the first electric push rod 3 drives the clamp 16 at the bottom of the first mounting plate 4 and the fourth mounting plate 7 to move downward, so that the two ends of the wire are fixed on the clamp 16 respectively.

[0026] The control component includes a screw rod 15 rotatably connected to the inside of the base plate 1, a slide 12 threadedly connected to the outside of the screw rod 15, a movable plate 11 slidably connected to the top of the base plate 1 and fixedly connected to the top of the slide 12, and a motor 14 fixedly connected to one side of the base plate 1. The end of the screw rod 15 close to the motor 14 passes through the inside of the base plate 1 and is fixedly connected to the output shaft of the motor 14.

[0027] The motor 14 is responsible for driving the screw rod 15 to rotate, thereby driving the movement of the slide plate 12. The moving slide plate 12 can drive the second electric push rod 13 to move back and forth to adjust the position of the connecting frame 19 to connect with the clamps 16 at different positions.

[0028] The clamps 16 near the first mounting plate 4 and the clamps 16 near the third mounting plate 6 are arranged horizontally opposite to each other, and the two groups of clamps 16 on the left and right are arranged opposite to each other to ensure that the wire is not twisted when moving through the clamps 16, ensuring the correct direction of tension application.

[0029] Working principle: Place the two ends of multiple wires to be tested on the clamp 16 located below. The first electric push rod 3 drives the clamp 16 at the bottom of the first mounting plate 4 and the fourth mounting plate 7 to move downward, so that the two ends of the wires are fixed on the clamp 16 respectively.

[0030] The second electric push rod 13 drives the connecting frame 19 to move toward the side close to the second electric push rod 13. The movement of the connecting frame 19 is connected with the connecting plate 17, so that the movable clamp 16 can apply tension to the thread. At the same time, the tension sensor 18 monitors the tensile strength of the sewing thread in real time.

[0031] After the single wire test is completed, the first electric push rod 3 runs to push the movable clamp 16 to reset. Then, the motor 14 drives the screw 15 to rotate, thereby driving the movement of the slide 12. The moving slide 12 can drive the second electric push rod 13 to move back and forth to adjust the position of the connecting frame 19 to connect with the clamps 16 in different positions. The first electric push rod 3 moves toward the side of the other clamp 16. The movement of the first electric push rod 3 can simultaneously drive the connecting frame 19 to move in the gap between the connecting plates 17. After the first electric push rod 3 and the connecting frame 19 are moved into place, the first electric push rod 3 can continuously apply tension to the clamp 16 through the cooperation of the connecting frame 19 and the connecting plate 17, thereby completing the tensile test of another wire. The cycle is repeated in sequence, and the tensile test of multiple wires can be completed simply and efficiently, avoiding the problem of frequent operation of the clamp 16. It can effectively improve the efficiency of testing the tensile strength of sewing threads and has strong practicality.

[0032] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
