[0023] Two mounting frames 4 are fixedly connected to the top outer wall of the base 1, a top plate 401 is fixedly connected to the top of the two mounting frames 4, two mounting plates 402 are fixedly connected to the bottom outer wall of the top plate 401, winding rollers 403 are rotatably connected to the opposite outer walls of the two mounting plates 402, and a pulling mechanism is installed on the top outer wall of the top plate 401.

[0024] The clamping mechanism further includes a servo motor 306 fixedly mounted on one end of the guide rail 3 , and the output shaft end of the servo motor 306 penetrates the guide rail 3 and is fixedly connected to one end of the bidirectional threaded rod 301 .

[0025] The pulling mechanism includes a stepper motor 5 and a reducer 501 fixedly mounted on the top outer wall of the top plate 401 . The output shaft of the stepper motor 5 is connected to the input end of the reducer 501 . The output end of the reducer 501 is fixedly connected to a main sprocket 502 .

[0026] The pulling mechanism also includes a transmission shaft 503 rotatably connected to the inner wall of a mounting frame 4, one end of the transmission shaft 503 passes through the mounting frame 4 and a mounting plate 402, and is fixedly connected to one end of the winding roller 403, and the end of the transmission shaft 503 away from the winding roller 403 passes through the mounting frame 4 and is fixedly connected to a secondary sprocket 504, and a chain 505 is installed on the outer wall of the main sprocket 502 and the secondary sprocket 504.

[0027] A controller 6 is fixedly mounted on the outer wall of the base 1 , and the tension sensor 2 and the stepper motor 5 are both electrically connected to the controller 6 .

[0028] The implementation principle of the pulling clamping device of the bandage tensile testing machine of the embodiment of the present application is as follows: when in use, one end of the bandage is placed between the two clamping blocks 303, and then the servo motor 306 is started through the clamping mechanism, and the output shaft of the servo motor 306 drives the bidirectional threaded rod 301 to rotate, and the bidirectional threaded rod 301 rotates on the inner surface of the two sliders 302. Since the threads of the bidirectional threaded rod 301 and the two sliders 302 are symmetrically arranged in opposite directions, the bidirectional threaded rod 301 drives the two sliders 302 to move relative to each other when rotating, and the two sliders 302 drive the two clamping blocks 303 to move relative to each other until the tooth plate 304 and the tooth block plate 305 are driven to contact the bandage, at which time the tooth plate 304 and the tooth block plate 305 will bite each other to firmly bite and lock the bandage;

[0029] Then the other end of the bandage is wound around the winding roller 403. Through the pulling mechanism, the controller 6 controls the stepper motor 5 to start. The output shaft of the stepper motor 5 rotates to transfer power to the main sprocket 502 through the reducer 501. The main sprocket 502 rotates through the chain 505 to drive the secondary sprocket 504 to rotate synchronously, and then the secondary sprocket 504 drives the transmission shaft 503 to rotate. When the transmission shaft 503 rotates, it can drive the winding roller 403 to rotate, thereby pulling the bandage. When the bandage is pulled, the tension sensor 2 can detect the tension in real time and transmit the data to the controller 6 for display. The detection process is intelligent, simple to operate, and easy to use.
