DETAILED DESCRIPTION

[0021] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 1-5 As shown, a yarn quality detection mechanism based on image processing of the utility model comprises a base 10, a detection box 11 is fixedly provided on the upper side of the base 10, a square opening 12 is opened on both the left and right sides of the detection box 11, four front-to-back symmetrical support rods 13 are fixedly provided on the upper side of the base 10, a circular ring 14 is fixedly provided on the upper side of the four support rods 13, and two circular rings 14 opposite to each other are provided with a clamping assembly in common;

[0023] The clamping assembly includes a first barrel 15 rotatably assembled with a rear ring 14, a second barrel 16 rotatably assembled with a front ring 14, the first barrel 15 and the second barrel 16 are arranged with their openings facing each other, a threaded section is provided on the outer wall of the second barrel 16 near the first barrel 15, and a cylinder 17 threadedly connected to the threaded section is rotatably assembled on the second barrel 16 near the first barrel 15;

[0024] When using the utility model, the user first inserts one end of the yarn wheel for sampling into the first barrel 15 on one side, and aligns the other end of the yarn wheel horizontally with the second barrel 16 on the same side. The user rotates the cylinder 17 on the side wall of the second barrel 16, and the cylinder 17 extends in the direction of the first barrel 15 to clamp the two ends of the yarn wheel. The empty yarn wheel is placed between the first barrel 15 and the second barrel 16 on the other side, and the cylinder 17 on the other side is rotated to clamp it. The user passes one end of the yarn wheel for sampling through the square opening 12 through the detection box 1 1. Wrap the yarn extending out of the other end of the detection box 11 around the upper side of the empty yarn wheel. The user then slowly rotates the second barrel 16 holding the empty yarn wheel. The second barrel 16 drives the first barrel 15 on the same side to rotate through the empty yarn wheel, and the yarn is wrapped around the surface of the empty yarn wheel. The yarn slowly passes through the detection box 11, and the sampling yarn wheel and the first barrel 15 and the second barrel 16 on the same side are synchronously pulled to rotate. The detection box 11 detects the yarn that passes slowly, avoiding manual detection and improving the accuracy of yarn detection.

[0025] The utility model clamps the sampled yarn wheel through the first barrel and the second barrel, clamps the empty yarn wheel through the first barrel and the second barrel on the other side, passes the yarn through the square opening and the detection box is wound on the upper side of the empty yarn wheel on the other side, rotates the yarn wheels on both sides, makes the yarn pass through the inside of the detection box evenly, and detects the yarn. The detection has high accuracy and does not require additional manual operation, thereby improving the detection efficiency.

[0026] Pulleys 18 are fixedly provided at the rear sides of the two first drums 15, and a belt 19 is provided between the two pulleys 18. A motor 20 is installed on the upper side of the base 10, and the output shaft of the motor 20 is in transmission connection with the left pulley 18.

[0027] When using the utility model, the user clamps the sampled yarn wheel and the empty yarn wheel, and then starts the motor 20. The output shaft of the motor 20 drives the left pulley 18 to rotate, and the left pulley 18 drives the right pulley 18 to rotate through the belt 19. The pulleys 18 on both sides synchronously drive the two second barrels 15 to rotate, thereby synchronously driving the two yarn wheels to rotate, ensuring that the yarn passes through the detection box 11 at a uniform speed, thereby ensuring the accuracy of the detection.

[0028] The two second barrels 16 are both provided with a limiter, which includes a first screw 21 rotatably mounted in the second barrel 16, and a round rod 22 is fixedly mounted at one end of the first screw 21 extending backward into the second barrel 16, and a plurality of arc plates 23 distributed in a circumference are rotatably mounted inside the second barrel 16, and a plurality of first springs 24 distributed in a linear manner are fixedly mounted between the side walls of the arc plates 23 and the side walls of the round rod 22;

[0029] When the utility model is used, after clamping both yarn wheels, the user rotates the two first screws 21 in turn, the first screw 21 drives the round rod 22 to rotate, the round rod 22 synchronously drives the arc plate 23 and the first spring 24 to rotate, the round rod 22 drives the arc plate 23 and the first spring 23 to rotate and extend to the rear side at the same time, after the arc plate 23 is fully extended into the yarn wheel, under the elastic action of the first spring 23, the arc plate 23 is completely in contact with the inner wall of the yarn wheel, thereby increasing the friction between the second barrel 16 and the yarn wheel, ensuring the normal rotation of the yarn wheel.

[0030] A long slot 30 is provided on the upper side of the base 10, a second screw 31 is rotatably mounted in the long slot 30, a block 32 threadedly connected to the second screw 31 is slidably mounted in the long slot 30, a square rod 33 is fixedly mounted on the upper side of the block 32, a Z-shaped plate 34 is rotatably mounted on the upper side of the square rod 33, and a second spring 35 is fixedly mounted between the lower side wall of the Z-shaped plate 34 and the upper side wall of the square rod 33;

[0031] When using the present invention, the user clamps the two yarn wheels and then clamps the yarn at one end of the sampled yarn wheel through the Z-shaped plate 34. The Z-shaped plate 34 clamps one end of the yarn on the upper side of the square rod 33 under the elastic action of the second spring 35. The user rotates the second screw 31, and the second screw 31 drives the block 32 to move, and synchronously drives the yarn end to move. The user winds the yarn end that passes through the detection box 11 around the empty yarn wheel and then performs detection, which makes it easier for the yarn end to pass through the detection box 11, thereby improving the convenience of using the present device.
