DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figures 1 to 5 As shown, a cotton yarn finished product inspection device according to an embodiment of the present invention comprises a placement box 1 and a detection box 2, wherein the placement box 1 is fixedly connected to one end of the detection box 2, a fixing component is arranged in the placement box 1, and the fixing component is used to fix the cotton yarn finished product, and a movable fixing clamp 20 is arranged in the detection box 2, and two negative pressure machines 24 are fixedly connected to the side of the fixing clamp 20 away from the placement box 1, and an extrusion component and a spraying component are arranged on the inner side of the placement box 1, and the spraying component is used to spray various chemical reagents on the surface of the cotton yarn, and the extrusion component is used to compress the cotton yarn to measure the compressive strength of the cotton yarn, and a plurality of optical probes are installed on the inner side of the placement box 1;

[0032] When working, the traditional cotton yarn testing equipment has relatively simple functions. Generally, it only uses the tensile test method to test the tensile effect of cotton yarn. Not only is the test effect general, but the operation is also cumbersome, which is not conducive to the random inspection of large-volume finished products.

[0033] By setting up the placement box 1 and the detection box 2, the rolled cotton yarn is fixed in the placement box 1 from above the placement box 1 through the fixing component, one end of the cotton yarn is pulled out, and then moved to the placement box 1 through the movable fixing clamp 20, one end of the cotton yarn is clamped and pulled into the detection box 2, and chemical reagents are sprayed on the surface of the cotton yarn through the spraying component. The chemical reagents can be substances such as weak acids. In order to simulate the influence of environmental factors encountered by the cotton yarn during actual use, a variety of reagents with different properties can be used to spray on the surface of the cotton yarn. After a period of time, the middle part of the cotton yarn is squeezed by the squeezing component until the cotton yarn breaks, and the squeezing force is recorded. The time of the breakage is observed by the optical probe. Through this setting, multiple control groups can be designed to test the compressive strength of the cotton yarn under different control groups such as when the cotton yarn is not sprayed with reagents, when different reagents are sprayed, and the length of time the reagents are sprayed. The various data of the cotton yarn finished product can be more comprehensively detected.

[0034] like Figures 1 to 5 As shown, a rear cover 11 is installed at one end of the detection box 2 away from the placement box 1, a servo motor 13 and a restraining rod 18 are fixedly connected in the rear cover 11, a screw 14 is fixedly connected to the output end of the servo motor 13, a horizontal frame 16 is fixedly connected between the fixing clamp 20 and the negative pressure machine 24, both ends of the horizontal frame 16 are slidably engaged with the detection box 2, the screw 14 is transmission-connected with one end of the horizontal frame 16, the restraining rod 18 passes through the other end of the horizontal frame 16, and the other ends of the restraining rod 18 and the screw 14 are rotationally engaged with the detection box 2;

[0035] During operation, the screw 14 is driven to rotate by the servo motor 13, thereby driving the horizontal frame 16 to move horizontally, thereby driving the fixing clamp 20 and the negative pressure machine 24 to move horizontally. When the fixing clamp 20 moves to the placement box 1, the negative pressure machine 24 is started to generate negative pressure at the port of the fixing clamp 20. The negative pressure will suck the end of the cotton yarn into the fixing clamp 20, and then the fixing clamp 20 will fix the cotton yarn, so that the cotton yarn can be pulled to move horizontally and keep the cotton yarn horizontal in the detection box 2 for subsequent extrusion detection.

[0036] like Figures 1 to 5 As shown, the spray assembly includes a storage tank 6, which is fixedly connected to the top of the detection box 2. Two spray heads 8 are fixedly connected to the top of the detection box 2, and the storage tank 6 is connected to the two spray heads 8.

[0037] During operation, different chemical reagents are stored in the storage tank 6, and then the liquid medicine in the storage tank 6 is atomized and sprayed into the interior of the detection box 2 through the nozzle 8, so that the liquid medicine adheres to the surface of the stretched cotton yarn. The amount of reagent sprayed onto the surface of the cotton yarn is controlled by the length of the spraying time, so as to simulate the corrosion of the cotton yarn during future use, so as to more accurately measure the service life of the cotton yarn and other data.

[0038] like Figures 1 to 7 As shown, two electric telescopic rods 10 are fixedly connected to the detection box 2, and the two electric telescopic rods 10 are centrally symmetrically arranged. A fixed ferrule 9 is fixedly connected to one end of the electric telescopic rod 10, and the two fixed ferrules 9 are spliced ​​into a circular ring. An electric blade is installed on the inner ring of the fixed ferrule 9, and a docking seat 12 adapted to the output end of the negative pressure machine 24 is fixedly connected to the middle of the rear cover 11;

[0039] During operation, the two electric telescopic rods 10 are extended to merge and splice the two fixed sleeves 9 into a ring, and the other end of the cotton yarn is fixed. In this way, the fixed positions of both ends of the cotton yarn are inside the detection box 2, and no accidents will occur during the downward pressure detection process. In this setting, after a cotton yarn is detected, the end of the cotton yarn close to the placement box 1 is cut off by the electric blade. At this time, the detected cotton yarn is in a broken state, and the cotton yarn fixed with the fixing clamp 20 is sucked into it by the negative pressure action of the negative pressure machine 24. Then the fixing clamp 20 approaches the fixing sleeve 9 to absorb the other half of the cotton yarn. After absorption, the two fixing sleeves 9 are separated. At this time, the end of the cotton yarn will be loosened and fixed to the fixing clamp 20 under the negative pressure absorption of the negative pressure machine 24, so that it is clamped by the fixing clamp 20 again, so that the fixing clamp 20 can pull out another section of cotton yarn for detection. Through this setting, a roll of cotton yarn only needs to be placed in the placement box 1, and the cotton yarn detection work can be repeated many times without manual assistance, which greatly improves the detection efficiency.

[0040] like Figures 1 to 7 As shown, the extrusion assembly includes two electric telescopic rods 7, and a pressing block 15 is provided at the bottom of the two electric telescopic rods 7, and the pressing block 15 is located on one side of the nozzle 8;

[0041] During operation, the electric telescopic rod 7 drives the pressing block 15 to press down, so that the bottom of the pressing block 15 presses the stretched cotton yarn until the cotton yarn breaks. A detection module is arranged inside the electric telescopic rod 7 to detect the output force, thereby obtaining the force applied when the cotton yarn breaks.

[0042] like Figures 1 to 7 As shown, a reduction motor 29 is fixedly connected to the bottom of one of the electric telescopic rods 7, and the reduction motor 29 is placed horizontally. The vertical section of the lower pressing block 15 is set in an elliptical shape. The output end of the reduction motor 29 is fixedly connected to the outer side of the lower pressing block 15 by one end, and the bottom of the other electric telescopic rod 7 is rotatably connected to the outer side of the lower pressing block 15;

[0043] During operation, the lower pressing block 15 is driven to rotate by the reduction motor 29. In combination with the elliptical setting of the lower pressing block 15, as the lower pressing block 15 rotates at different angles, the bottom area of ​​the lower pressing block 15 will change. When the bottom area changes, the pressure will change. In this way, the compression resistance of the cotton yarn under different pressures can be detected, further improving the comprehensiveness of the detection.

[0044] like Figures 1 to 7As shown, the fixing clip 20 is made of a bent elastic metal sheet, both ends of the fixing clip 20 are fixedly connected to a blocking pad 22 made of an elastic material, the top and bottom of the fixing clip 20 are fixedly connected to a magnet 21, the rear end of the fixing clip 20 is fixedly connected to a winding box, a motor is fixedly connected to the winding box, a cable 23 is connected between the two magnets 21, and the middle part of the cable 23 is fixedly connected to the output end of the motor;

[0045] During operation, both sides of the fixing clamp 20 are blocked by the blocking pads 22, so that the suction force will only act on the end of the fixing clamp 20. By rotating the motor, the cable 23 is wound around the output end of the motor, and the opening of the fixing clamp 20 can be unfolded to clamp the cotton yarn. As the cable 23 is released, the two ends of the fixing clamp 20 are merged under the action of their own elasticity and are firmly sucked by the two magnets 21, ensuring that the fixed end of the cotton thread will not loosen due to pressure.

[0046] like Figures 1 to 7 As shown, a clamping groove 28 is provided on one side of the placement box 1 close to the detection box 2, the clamping groove 28 is narrow at the top and wide at the bottom, and an elastic pad is fixed to the wall of the clamping groove 28, a notch groove 5 is provided on the top of one end of the placement box 1 close to the placement box 1, and a protective cover 3 is rotatably connected to the top of the placement box 1;

[0047] During operation, when placing the cotton yarn roll for the first time, the end of the cotton yarn is pulled out and inserted into the clamping groove 28 from top to bottom, so that the end of the cotton yarn can be sucked into it by the fixing clip 20. The elastic pad is provided to provide friction to the cotton yarn to ensure that the end of the cotton yarn can be normally clamped in the clamping groove 28 at the beginning. The notch groove 5 is provided to provide enough space for the cotton yarn to be inserted from top to bottom. When all are placed, the protective cover 3 is closed. There is also a flip-up cover on the protective cover 3 to close the notch groove 5 so that the reagent inside will not be emitted outward.

[0048] like Figures 1 to 7 As shown, the fixing assembly includes a sleeve rod 25, and two sets of electric support rods 26 are installed on the surface of the sleeve rod 25. The sleeve rod 25 is located in the middle of the placement box 1. One end of the sleeve rod 25 is connected to a driving motor 4 for driving the sleeve rod 25 to rotate. One side of the placement box 1 is open, and the open end of the placement box 1 is rotatably connected to a side door 27;

[0049] During operation, the finished cotton yarn is rolled on the outside of the tube. The tube is inserted into the sleeve rod 25 from the side, opened outward by the electric support rod 26, and the tube is fixed. Then, when the clamp 20 is fixed to pull the cotton yarn, the drive motor 4 rotates synchronously to ensure the normal release process of the cotton yarn. The side door 27 is set to facilitate the finished cotton yarn to be inserted into the outside of the sleeve rod 25.

[0050] like Figures 1 to 7As shown, a plurality of flow grooves 17 are provided at the bottom of the detection box 2, a base 19 is fixedly connected to the bottom of the detection box 2, the interior of the base 19 is hollow, and the base 19 is connected to the plurality of flow grooves 17;

[0051] Excess reagents will be collected in the flow channel 17 and then recovered to the base 19, thereby reducing the problem of reagent accumulation at the bottom.

[0052] During operation, through the arrangement of the placement box 1 and the detection box 2, the rolled cotton yarn is fixed in the placement box 1 from above the placement box 1 through the fixing component, one end of the cotton yarn is pulled out, and then moved to the placement box 1 through the movable fixing clamp 20, one end of the cotton yarn is clamped and pulled into the detection box 2, and chemical reagents are sprayed on the surface of the cotton yarn through the spraying component. The chemical reagents can be substances such as weak acids. In order to simulate the influence of environmental factors encountered by the cotton yarn during actual use, a variety of reagents with different properties can be used to spray on the surface of the cotton yarn. After a period of time, the middle part of the cotton yarn is squeezed by the squeezing component until the cotton yarn breaks and the squeezing force is recorded. The time of the breakage is observed by the optical probe. Through this arrangement, multiple control groups can be designed to test the compressive strength of the cotton yarn under different control groups such as when the cotton yarn is not sprayed with reagents, when different reagents are sprayed, and the length of time the reagents are sprayed. This can more comprehensively detect various data of the finished cotton yarn.

[0053] The screw rod 14 is driven to rotate by the servo motor 13, thereby driving the horizontal frame 16 to move horizontally, thereby driving the fixing clamp 20 and the negative pressure machine 24 to move horizontally. When the fixing clamp 20 moves into the placement box 1, the negative pressure machine 24 is started to generate negative pressure at the port of the fixing clamp 20. The negative pressure will suck the end of the cotton yarn into the fixing clamp 20, and then the fixing clamp 20 will fix the cotton yarn, so that the cotton yarn can be pulled to move horizontally, and the cotton yarn can be kept horizontal in the detection box 2 to accept subsequent extrusion detection;

[0054] By storing different chemical reagents in the storage tank 6, and then spraying the liquid in the storage tank 6 into the interior of the detection box 2 through the nozzle 8, the liquid is attached to the surface of the stretched cotton yarn, and the amount of the reagent sprayed on the surface of the cotton yarn is controlled by the length of the spraying time, so as to simulate the corrosion of the cotton yarn in the future use process, so as to more accurately measure the service life of the cotton yarn and other data;

[0055] By extending the two electric telescopic rods 10, the two fixed ferrules 9 are combined and spliced ​​into a ring, and the other end of the cotton yarn is fixed. In this way, the fixed positions of the two ends of the cotton yarn are inside the detection box 2, and no accidents will occur during the downward pressure detection process. In this setting, when a cotton yarn is detected, the end of the cotton yarn close to the placement box 1 is cut off by the electric blade. At this time, the detected cotton yarn is in a broken state, and the cotton yarn fixed with the fixed clamp 20 is sucked into it by the negative pressure of the negative pressure machine 24. Then the fixed clamp 20 approaches the fixed ferrule 9 to absorb the other half of the cotton yarn. After absorption, the two fixed ferrules 9 are separated. At this time, the end of the cotton yarn will be loosened and fixed to the fixed clamp 20 under the negative pressure absorption of the negative pressure machine 24, so that it will be clamped by the fixed clamp 20 again. In this way, the fixed clamp 20 can pull out another section of cotton yarn for detection. Through this setting, a roll of cotton yarn only needs to be placed in the placement box 1, and the cotton yarn detection work can be repeated many times without manual assistance, which greatly improves the detection efficiency.

[0056] The electric telescopic rod 7 drives the pressing block 15 to press down, so that the bottom of the pressing block 15 presses the stretched cotton yarn until the cotton yarn breaks. The electric telescopic rod 7 is provided with a detection module inside to detect the output force, so as to obtain the force applied when the cotton yarn breaks.

[0057] The lower pressing block 15 is driven to rotate by the reduction motor 29, and the elliptical setting of the lower pressing block 15 is matched. As the lower pressing block 15 rotates at different angles, the bottom area of ​​the lower pressing block 15 will change. When the bottom area changes, the pressure will change. In this way, the compression resistance of the cotton yarn under different pressures can be detected, further improving the comprehensiveness of the detection.

[0058] The two sides of the fixing clamp 20 are blocked by the blocking pads 22, so that the suction force will only act on the end of the fixing clamp 20. By rotating the motor, the cable 23 is wound around the output end of the motor, and the opening of the fixing clamp 20 can be opened to clamp the cotton yarn. With the release of the cable 23, the two ends of the fixing clamp 20 are combined under the action of their own elasticity and firmly sucked by the two magnets 21, ensuring that the fixed end of the cotton thread will not loosen due to pressure;

[0059] When placing the cotton yarn roll for the first time, the end of the cotton yarn is pulled out and inserted into the clamping groove 28 from top to bottom, so that the end of the cotton yarn can be sucked into it by the fixing clip 20. The setting of the elastic pad is to provide friction to the cotton yarn to ensure that the end of the cotton yarn can be normally clamped in the clamping groove 28 at the beginning. The setting of the notch groove 5 is to facilitate the cotton yarn to be clamped from top to bottom, and there is enough space. When all are placed, the protective cover 3 is closed. There is also a flip cover on the top of the protective cover 3 to close the notch groove 5, so that the reagent inside will not be emitted outward;

[0060] The finished cotton yarn is rolled on the outside of the drum. The drum is inserted into the sleeve rod 25 from the side, and the drum is fixed by opening it outward through the electric support rod 26. Then, when the clamp 20 pulls the cotton yarn, the drive motor 4 rotates synchronously to ensure the normal release process of the cotton yarn. The side door 27 is set to facilitate the cotton yarn to be inserted into the outside of the sleeve rod 25.

[0061] Excess reagents will be collected in the flow channel 17 and then recovered to the base 19, thereby reducing the problem of reagent accumulation at the bottom.
