Gears are fixedly sleeved on the shaft walls of the two rotating shafts on the outer side of the frame, and the two gears are meshed with each other. When performing tensile testing on yarn, this device can only test a single yarn, resulting in low testing efficiency. Utility Model Content

[0004] The technical problem to be solved by this invention is that in the prior art, yarn is tested one by one, which results in low testing efficiency.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A yarn quality testing device includes a base with several supporting legs fixedly connected to the lower end of the base, and a winding mechanism connected to the base. A first mounting plate and a second mounting plate are fixedly connected to both sides of the upper end of the base. Several tension sensors are fixedly connected to the inner side of the first mounting plate at intervals. A first connecting frame is fixedly connected to the front end of each tension sensor. A pad is fixedly connected to the inner side of the second mounting plate. Several second connecting frames are fixedly connected to the front end of the pad. The first and second connecting frames are both U-shaped and symmetrically distributed.

[0007] The winding mechanism includes a motor and winding plates. The motor is fixed to the front end of the base and drives several winding plates located on the upper end of the base to rotate vertically. The winding plates are provided with threading holes.

[0008] Furthermore, a connecting rod is fixedly connected to the output end of the motor, and several first bevel gears are fixedly connected to the connecting rod. Each of the first bevel gears is meshed with a second bevel gear. A connecting shaft is fixedly connected to the upper end of the second bevel gear. The upper end of the connecting shaft extends rotatably out of the base and is fixedly connected to a turntable. The winding plate is fixedly connected to the upper end of the turntable.

[0009] Furthermore, the base is provided with several tooth grooves, and the meshing first bevel gear and second bevel gear are rotatably disposed in the tooth grooves.

[0010] Furthermore, a limiting ring is fixed to the lower end of the turntable. The limiting ring has an inverted T-shaped cross-section. Several limiting grooves are provided on the upper end of the base. The limiting ring rotates and fits into the limiting grooves.

[0013] Furthermore, a detection terminal is installed at the front end of the base, and the tensile sensor is connected to the detection terminal via a cable.

[0014] The beneficial effects of this utility model by adopting the above structure are as follows:

[0015] The device is equipped with a winding mechanism. Driven by a motor, several sets of first and second bevel gears mesh and transmit power, thereby simultaneously driving multiple winding plates to rotate. This causes the yarn to wind around the winding plates and be stretched, thus enabling simultaneous detection of multiple yarns. Attached Figure Description

Detailed Implementation

[0023] like Figure 1-5 As shown, a yarn quality testing device includes a base 1, with several support legs 101 fixedly connected to the lower end of the base 1, and a winding mechanism 4 connected to the base 1. A first mounting plate 102 and a second mounting plate 103 are fixedly connected to both sides of the upper end of the base 1. Several spaced tension sensors 2 are fixedly connected to the inner side of the first mounting plate 102, and a first connecting frame 201 is fixedly connected to the front end of each tension sensor 2. A pad 3 is fixedly connected to the inner side of the second mounting plate 103, and a first connecting bracket 201 is fixedly connected to the front end of the pad 3. There are several second connecting frames 301. The first connecting frame 201 and the second connecting frame 301 are both U-shaped and symmetrically distributed. A detection terminal 6 is installed at the front end of the base 1. The tension sensor 2 is connected to the detection terminal 6 through a cable. After the two ends of the yarn 5 are connected to the first connecting frame 201 and the second connecting frame 301, the yarn winding mechanism 4 is used to wind up the yarn 5 and stretch it. Then, the tension sensor 2 is used to detect the tension of the yarn 5. The tensile quality of the yarn 5 is judged by the tension generated when different yarns 5 break.

[0024] like Figure 3 , 4As shown, the winding mechanism 4 includes a motor 401 and winding plates 407. The motor 401 is fixedly connected to the front end of the base 1. The motor 401 drives several winding plates 407 located on the upper end of the base 1 to rotate vertically. The winding plates 407 are provided with threading holes 408. A connecting rod 402 is fixedly connected to the output end of the motor 401. Several first bevel gears 403 are fixedly connected to the connecting rod 402. Each of the first bevel gears 403 is meshed with a second bevel gear 404. A connecting rod is fixedly connected to the upper end of the second bevel gear 404. Shaft 405, the upper end of which extends rotatably from the base 1 and is fixedly connected to a turntable 406. The winding plate 407 is fixedly connected to the upper end of the turntable 406. The base 1 is provided with several toothed grooves 104. The meshing first bevel gear 403 and second bevel gear 404 are rotatably disposed in the toothed grooves 104. The winding plate 407 is provided with wire-locking grooves 409 symmetrically distributed on both sides of the threading hole 408. The motor 401 drives several winding plates 407 to rotate simultaneously, thereby enabling simultaneous detection of multiple yarns 5.

[0025] like Figure 3-5 As shown, a limiting ring 410 is fixedly connected to the lower end of the turntable 406. The limiting ring 410 has an inverted T-shaped cross-section. Several limiting grooves 105 are provided on the upper end of the base 1. The limiting ring 410 is rotatably fitted in the limiting grooves 105. A first annular groove 106 is provided at the lower end of the limiting groove 105, and a second annular groove 411 is provided at the lower end of the limiting ring 410. Several balls 412 are movably arranged between the first annular groove 106 and the second annular groove 411. The balls 412 support the limiting ring 410 to rotate in the limiting groove 105. The rotation of the limiting ring 410 improves the rotational stability of the turntable 406, while the rolling support of the balls 412 reduces the frictional resistance of the turntable 406.

[0026] In use, this invention involves sequentially threading multiple yarns 5 through the threading holes 408 of multiple winding plates 407. The two ends of the yarns 5 are fixedly connected to the first connecting bracket 201 and the second connecting bracket 301 on opposite sides of the winding plate 407. The output of the motor 401 drives the connecting rod 402 to rotate, which in turn drives several first bevel gears 403 to rotate, which in turn drives the corresponding second bevel gears 404 to rotate, which in turn drives the corresponding connecting shaft 405 to rotate, which in turn drives the corresponding turntable 406 to rotate, which in turn drives the corresponding winding plate 407 to rotate. The rotation of the winding plate 407 causes the yarns 5, which have passed through the threading holes 408, to wind around the winding plate 407. In the 409 slot of 07, when the turntable 406 rotates, the limiting ring 410 rotates within the limiting groove 105 to improve the stability of the turntable 406 rotation. When the limiting ring 410 rotates, the rolling of several balls 412 between the first groove 106 and the second groove 411 supports the rotation of the limiting ring 410, thereby reducing its rotational frictional resistance. The rotation of the winding plate 407 causes the yarn 5 to wind, thereby generating a stretching effect on the yarn 5. The tensile force of the yarn 5 is detected by the tension sensor 2, and the detection data of the tension sensor 2 is received by the detection terminal 6. The tensile strength is judged to meet the standard by the tensile force value recorded when the yarn 5 breaks.

[0027] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
