The angles between the high-contrast background board and the high-definition industrial camera and the workbench are both 45 degrees, which is convenient for the device to automatically collect appearance data and automatically analyze whether the appearance meets the standards.
[0012] The operation method of the device: Step 1: Place the yarn bobbin. The user places the yarn bobbin wound with yarn on the surface of the placing rod and limits the yarn bobbin on one side of the first support rod by rotating the rotating part. Step 2: Fix the yarn. Pass one end of the yarn through the fixed block and the movable block and fix it to one end of the binding hook. Lock one end of the yarn through the second electric push rod, the movable block and the fixed block. Drive the rotating rod, the turntable, the fixed block and the movable block to rotate through the second motor, wind the yarn on the surfaces of the fixed block and the movable block, and finally make the elastic lock piece fit tightly with the rotating rod through the first electric push rod and the inner inclined sleeve, so as to further firmly lock one end of the yarn. Step 3: Determine the original length. Drive the first support rod, the second support rod and one end of the yarn to move through the first motor, the first threaded rod and the moving plate. Pull the clamping part through the clamping groove and the tension sensor. When the tension sensor detects the tension, the first motor stops working at this time. At the same time, detect the original length of the yarn through the first distance sensor and the second distance sensor. Step 4: Appearance judgment. The rotating third threaded rod can drive the moving frame, the high-contrast background board and the high-definition industrial camera to move step by step. The photos taken by the high-contrast background board and the high-definition industrial camera are stored in the intelligent control panel and spliced one by one. Compare the collected images with the standard image template to judge whether the appearance of the yarn meets the standards. Step 5: Tensile test. The two clamping blocks lock the moving block through the third motor and the reverse threaded rod. The swivel block, the tensile sensor, and the card slot move upward through the fourth motor and the second threaded rod. Replace the card slot at the bottom of the swivel block with the tensile sensor engaged. The clamping block no longer locks the moving block through the third motor and the reverse threaded rod. At this time, the moving plate and the turntable move through the first motor and the first threaded rod to stretch the yarn. The force value during the stretching process is collected in real time by the tensile sensor at the bottom of the swivel block. The elongation data is collected in real time by the first distance sensor and the second distance sensor. By calculating the ratio of the maximum elongation of the yarn during the stretching process to the original length, the elastic elongation rate is obtained. After the stretching is completed, the yarn is no longer taut through the first threaded rod and the first motor. At this time, the moving block and the clamping member are reset. The moving block is fixed again by the clamping block. The tensile sensor at the bottom of the swivel block is reset again through the fourth motor and the second threaded rod. At this time, the clamping member and the card slot are engaged. Again, through the first threaded rod and the first motor, the second support rod and the turntable at one end, the length of the yarn recovered after release is obtained through the first distance sensor and the second distance sensor. Finally, by measuring the ratio of the length of the yarn recovered after release to the stretching length, the elastic recovery rate is obtained. Finally, these data are compared with the standard parameters to evaluate the elastic performance of the yarn; Step 6: Cyclic fatigue test. After the tensile test is completed, by repeatedly stretching and recovering the yarn multiple times, the elastic fatigue situation in actual use is simulated. After each cycle, the change in the elastic index of the yarn is measured. Finally, the degree of elastic attenuation after multiple cycles is analyzed to judge the elastic durability of the yarn.
[0013] When the user uses this device to perform high-elasticity quality detection, the user places the yarn reel wound with yarn on the surface of the placement rod, limits the yarn reel to one side of the first support rod by rotating the rotating part, passes one end of the yarn through between the fixed block and the movable block, and fixes one end of the yarn to one end of the binding hook. The user places enough yarn between the second support rod and the third support rod. The output end of the second electric push rod extends, driving the movable block to rotate. The yarn is locked at one end through the fixed block and the movable block. Then, through the triangular groove at the top of the fixed block and the triangular teeth at the bottom of the movable block, the yarn can be further locked. Then, the output end of the second motor drives the turntable, the fixed block and the movable block to rotate through the rotating rod. At this time, the fixed block and the movable block drive the yarn to rotate, so as to wind the yarn on the surfaces of the fixed block and the movable block, further fixing the yarn. Finally, the first electric push rod pushes the inner inclined sleeve to move inside the chute. Through the inclined surfaces of the inner inclined sleeve and the elastic lock piece, the inner wall of the elastic lock piece can be closely attached to the rotating rod, so that the rotating rod, the turntable, the fixed block and the movable block can be further locked, and then one end of the yarn can be firmly locked, avoiding slipping or loosening during the subsequent detection process and affecting the detection data. This device first determines the original length of the yarn. The first motor, the first sliding rod and the first threaded rod can make the moving plate, the first support rod, the second support rod and one end of the yarn move. When the yarn pulls the binding hook, the moving block and the clamping part to move, at this time, the clamping part pulls the clamping groove and the tension sensor through the clamping part. When the tension sensor detects the tension, the first motor stops working. At the same time, the original length of the yarn is detected through the first distance sensor and the second distance sensor. The original length is the sum of the length between the first distance sensor and the second distance sensor and the length between the second distance sensor and the binding hook. The length between the second distance sensor and the binding hook is a fixed value. First, data on the surface shape of the yarn is collected through a high-definition industrial camera and a high-contrast background board. The fifth motor and the third threaded rod make the moving frame, the high-contrast background board and the high-definition industrial camera move step by step. The photos taken by the high-contrast background board and the high-definition industrial camera are stored inside the intelligent control panel. The intelligent control panel splices the taken photos one by one, so as to splice the collected photos into a complete one. Because the surface color of the high-contrast background board forms a sharp contrast with the color of the yarn, it is more convenient for the comparison of appearance data. The collected image is compared with the standard image template. Through algorithms such as edge detection and texture analysis, defects such as the number of yarn hairs, uneven thickness, and surface defects of the yarn are identified, so as to judge whether the appearance of the yarn meets the standard. If the collected data exceeds the standard, the intelligent control panel marks the non-conforming position. After the appearance detection is qualified, the third motor and the reverse threaded rod make the two clamping blocks approach each other until the moving block is locked. Then, the fourth motor and the second threaded rod make the rotating ring block, the tension sensor and the clamping groove move upward, so that the clamping groove at the bottom of the rotating ring block is engaged with the clamping part. The tension and elasticity are detected through the tension sensor at the bottom of the rotating ring block.After the replacement is completed, the clamping block no longer locks the moving block through the third motor and the reverse threaded rod. At this time, the moving plate and the turntable are moved through the first motor and the first threaded rod, so that the yarn can be stretched. The friction between the moving block and the limiting groove can be reduced through the rolling groove and the ball. The detection is to stretch to a specified length at a constant speed and then release. The force value during the stretching process is collected in real time by a set of tension sensors at the bottom of the rotating ring block. The elongation data is collected in real time by the first distance sensor and the second distance sensor. By calculating the ratio of the maximum elongation of the yarn during the stretching process to the original length, the elastic elongation rate is obtained. After the stretching is completed, the yarn is no longer tightened through the first threaded rod and the first motor. At this time, the moving block and the clamping part are reset, and the moving block is fixed again through the clamping block. The set of tension sensors at the bottom of the rotating ring block is reset through the fourth motor and the second threaded rod. At this time, the clamping part and the clamping groove are engaged. Again, through the first threaded rod, the first motor, the second support rod at one end, and the turntable, the length recovered by the yarn after release is obtained through the first distance sensor and the second distance sensor. Finally, by measuring the ratio of the length recovered by the yarn after release to the stretching length, the elastic recovery rate is obtained. Finally, these data are compared with the standard parameters to evaluate the elastic performance of the yarn. After the stretching detection is completed, the elastic fatigue situation in actual use is simulated by performing multiple repeated stretching and recovery cycles on the yarn. After each cycle, the change in the elastic index of the yarn is measured. Finally, the degree of elastic attenuation after multiple cycles is analyzed to judge the elastic durability of the yarn. After the detection is completed, the user only needs to remove the yarn after this detection and replace it with a new yarn to be detected to continue the detection. This device is simple and convenient to operate, has a high degree of intelligence, can automatically complete the detection of high elastic performance, and does not require the user to operate repeatedly for a long time. It can not only reduce the workload of the user, but also quickly and accurately detect the high elastic performance of the electrostatic high elastic yarn, and can also improve production efficiency and product quality, and reduce production costs and quality risks.

The moving block 25 is fixed again by the clamping block 31. The fourth motor 37 and the second threaded rod 38 are used to reset a set of tension sensors 39 at the bottom end of the swivel block 36. At this time, the clamping member 27 and the card slot 40 are engaged. The first threaded rod 5 and the first motor 6 are used again to drive the second support rod 11 and the turntable 12 at one end. The length of the yarn recovered after release is obtained through the first distance sensor 41 and the second distance sensor 43. Finally, by measuring the ratio of the length of the yarn recovered after release to the stretching length, the elastic recovery rate is obtained, which facilitates the automatic conversion of different-precision tension sensors 39 by this device; Please refer to Figure 2 and Figure 8, in this embodiment, the acquisition mechanism includes a first distance sensor 41. The first distance sensor 41 is arranged in the middle of the second support rod 11. A fourth support rod 42 is fixedly connected to the middle of the workbench 1. A second distance sensor 43 is arranged at the top of the fourth support rod 42, and the position of the second distance sensor 43 corresponds to that of the first distance sensor 41. A moving frame 44 is arranged in the middle of the workbench 1. The bottom end of the moving frame 44 is slidably connected with a third slide rod 47, and both ends of the third slide rod 47 are fixedly connected to the workbench 1. The bottom end of the moving frame 44 is connected with a third threaded rod 49 through a thread, and one end of the third threaded rod 49 is connected to the workbench 1 through a bearing. A fifth motor 48 is arranged at one end of the workbench 1, and the output end of the fifth motor 48 is fixedly connected to one end of the third threaded rod 49. A high-contrast background plate 45 is arranged at one end of the moving frame 44. A high-definition industrial camera 46 is arranged at the other end of the moving frame 44, and the high-definition industrial camera 46 corresponds to the high-contrast background plate 45. The angles between the high-contrast background plate 45 and the high-definition industrial camera 46 and the workbench 1 are both 45 degrees. The original length of the yarn is detected by the first distance sensor 41 and the second distance sensor 43. The original length is the sum of the length between the first distance sensor 41 and the second distance sensor 43 and the length between the second distance sensor 43 and the tying hook 26. The length between the second distance sensor 43 and the tying hook 26 is a fixed value. First, data on the surface shape of the yarn is collected by the high-definition industrial camera 46 and the high-contrast background plate 45. The output end of the fifth motor 48 drives the third threaded rod 49 to rotate. The rotating third threaded rod 49 can drive the moving frame 44, the high-contrast background plate 45, and the high-definition industrial camera 46 to move step by step. The movement of the moving frame 44 is limited by the third slide rod 47. The photos taken by the high-contrast background plate 45 and the high-definition industrial camera 46 are stored inside the intelligent control panel 2. The intelligent control panel 2 splices the taken photos one by one, so as to splice the collected photos into a complete one. Since the surface color of the high-contrast background plate 45 forms a sharp contrast with the color of the yarn, it is more convenient for comparing appearance data. The collected image is compared with the standard image template. Through algorithms such as edge detection and texture analysis, defects such as the number of yarn hairs, uneven thickness, and surface defects are identified, so as to judge whether the appearance of the yarn meets the standard. If the collected data exceeds the standard, at this time, the intelligent control panel 2 marks the non-conforming position, which is convenient for this device to automatically collect appearance data and automatically analyze whether the appearance meets the standard; It should be noted that one end of the first threaded rod 5 is connected to the workbench 1 through a bearing. The control end of the intelligent control panel 2 is electrically connected to an external power supply. The control end of the first motor 6 is electrically connected to the intelligent control panel 2, facilitating the operation of the device. The control ends of the second motor 15, the first electric push rod 18, and the second electric push rod 21 are all electrically connected to the intelligent control panel 2, facilitating the operation of the device. The control ends of the third motor 33, the fourth motor 37, and the tension sensor 39 are all electrically connected to the intelligent control panel 2, facilitating the operation of the device; Operating method of the device: Step 1: Place the yarn bobbin 9. The user places the yarn bobbin 9 wound with yarn on the surface of the placing rod 8 and limits the yarn bobbin 9 on one side of the first support rod 7 by rotating the rotating part 10; Step 2: Fix the yarn. Pass one end of the yarn through the fixing block 19 and the movable block 20 and fix it to one end of the tying hook 26. Lock one end of the yarn through the second electric push rod 21, the movable block 20, and the fixing block 19. Drive the rotating rod 14, the turntable 12, the fixing block 19, and the movable block 20 to rotate through the second motor 15, wind the yarn around the surfaces of the fixing block 19 and the movable block 20, and finally make the elastic lock piece 16 closely fit with the rotating rod 14 through the first electric push rod 18 and the inner inclined sleeve 17, further firmly locking one end of the yarn; Step 3: Determine the original length. Drive the first support rod 7, the second support rod 11, and one end of the yarn to move through the first motor 6, the first threaded rod 5, and the moving plate 3. The clamping part 27 pulls the clamping groove 40 and the tension sensor 39. When the tension sensor 39 detects the tension, the first motor 6 stops working at this time. At the same time, detect the original length of the yarn through the first distance sensor 41 and the second distance sensor 43; Step 4: Appearance judgment. The rotating third threaded rod 49 can drive the moving frame 44, the high-contrast background plate 45, and the high-definition industrial camera 46 to move step by step. The photos taken by the high-contrast background plate 45 and the high-definition industrial camera 46 are stored in the intelligent control panel 2 and spliced one by one. Compare the collected images with the standard image template to determine whether the appearance of the yarn meets the standard; Step 5: Tensile test. Use the third motor 33 and the reverse threaded rod 34 to lock the two clamping blocks 31 to the moving block 25. Use the fourth motor 37 and the second threaded rod 38 to move the swivel block 36, the tensile sensor 39, and the card slot 40 upward. Replace the card slot 40 at the bottom of the swivel block 36 with the tensile sensor 39 engaged. Use the third motor 33 and the reverse threaded rod 34 to release the clamping of the moving block 25 by the clamping block 31. At this time, use the first motor 6 and the first threaded rod 5 to move the moving plate 3 and the turntable 12 to stretch the yarn. Use the tensile sensor 39 at the bottom of the swivel block 36 to collect the force value during the stretching process in real time. Use the first distance sensor 41 and the second distance sensor 43 to collect the elongation data in real time. Calculate the ratio of the maximum elongation to the original length of the yarn during the stretching process to obtain the elastic elongation rate. After the stretching is completed, use the first threaded rod 5 and the first motor 6 to relieve the tension of the yarn. At this time, the moving block 25 and the clamping member 27 are reset. Fix the moving block 25 again with the clamping block 31. Use the fourth motor 37 and the second threaded rod 38 to reset the tensile sensor 39 at the bottom of the swivel block 36. At this time, the clamping member 27 and the card slot 40 are engaged. Again, use the first threaded rod 5 and the first motor 6 to move the second support rod 11 and the turntable 12 at one end. Use the first distance sensor 41 and the second distance sensor 43 to obtain the length of the yarn recovered after release. Finally, measure the ratio of the length of the yarn recovered after release to the stretching length to obtain the elastic recovery rate. Finally, compare these data with the standard parameters to evaluate the elastic performance of the yarn; Step 6: Cyclic fatigue test. After the tensile test is completed, simulate the elastic fatigue situation in actual use by performing multiple repeated stretching and recovery cycles on the yarn. After each cycle, measure the change in the elastic index of the yarn. Finally, analyze the degree of elastic attenuation after multiple cycles to judge the elastic durability of the yarn.
[0018] When the user uses the device to perform high elasticity quality inspection, the user places the yarn disk 9 wrapped with yarn on the surface of the placement rod 8, limits the yarn disk 9 on one side of the first support rod 7 by rotating the rotating member 10, passes one end of the yarn through between the fixed block 19 and the movable block 20, and fixes one end of the yarn on one end of the binding hook 26. The user places enough yarn between the second support rod 11 and the third support rod 22, and the output end of the second electric push rod 21 extends to drive the movable block 20 to rotate, and locks one end of the yarn through the fixed block 19 and the movable block 20, and then the yarn can be further locked through the triangular groove at the top of the fixed block 19 and the triangular teeth at the bottom of the movable block 20. Then the output end of the second motor 15 drives the rotating rod 14 to rotate, and the rotating rod 14 drives the turntable 12, The fixed block 19 and the movable block 20 rotate, and at this time the fixed block 19 and the movable block 20 drive the yarn to rotate, so that the yarn is wound around the surfaces of the fixed block 19 and the movable block 20, and the yarn is further fixed. Finally, the inner bevel sleeve 17 is pushed to move inside the slide groove 13 by the first electric push rod 18. At this time, the inclined surface of the inner wall of the inner bevel sleeve 17 and the inclined surface of the surface of the elastic locking piece 16 conflict with each other, so that the inner wall of the elastic locking piece 16 can fit tightly with the rotating rod 14, so that the rotating rod 14, the turntable 12, the fixed block 19 and the movable block 20 can be locked in one step, and then one end of the yarn can be firmly locked to avoid slipping or loosening in the subsequent detection process, which affects the detection data. The device first determines the original yarn length, and the output end of the first motor 6 drives the first screw The threaded rod 5 rotates, and one end of the plate 3 can be moved through the first threaded rod 5. At this time, the moving plate 3 slides on the surface of the first slide bar 4, and the movement of the moving plate 3 is limited by the first slide bar 4. The moving plate 3 drives the first support rod 7, the second support rod 11 and one end of the yarn to move. When the yarn pulls the binding hook 26, the moving block 25 and the clamping member 27 to move, the friction between the limiting groove 24 and the moving block 25 can be reduced by the rolling groove 28 and the ball 29. At this time, the clamping member 27 pulls the clamping groove 40 and the tension sensor 39. When the tension sensor 39 detects the tension, the first motor 6 stops working. At the same time, the original length of the yarn is detected by the first distance sensor 41 and the second distance sensor 43. The original length is the first distance sensor 41. The sum of the length between the second distance sensor 43 and the length between the second distance sensor 43 and the hook 26, the length between the second distance sensor 43 and the hook 26 is a fixed value, firstly, the surface shape of the yarn is collected through the high-definition industrial camera 46 and the high-contrast background plate 45, the output end of the fifth motor 48 drives the third threaded rod 49 to rotate, and the rotating third threaded rod 49 can drive the mobile frame 44, the high-contrast background plate 45 and the high-definition industrial camera 46 to move step by step, and the movement of the mobile frame 44 is limited by the third sliding bar 47, and the photos taken by the high-contrast background plate 45 and the high-definition industrial camera 46 are stored in the intelligent control panel 2, and the photos taken are spliced one by one through the intelligent control panel 2,Thus, the collected photos are assembled into a complete one. Since the surface color of the high-contrast background plate 45 forms a sharp contrast with the color of the yarn, it is more convenient to compare the appearance data. The collected image is compared with the standard image template. Through algorithms such as edge detection and texture analysis, defects such as the number of yarn hairs, uneven thickness, and surface defects are identified, so as to judge whether the appearance of the yarn meets the standard. When the collected data exceeds the standard, the intelligent control panel 2 marks the non-conforming positions at this time. After the appearance inspection is qualified, the output end of the third motor 33 drives the reverse threaded rod 34 to rotate. Through the rotating reverse threaded rod 34, the two clamping blocks 31 approach each other until the moving block 25 is locked. Then, the output end of the fourth motor 37 drives the second threaded rod 38 to rotate. Through the rotating second threaded rod 38, the rotating ring block 36, the tension sensor 39, and the card slot 40 move upward, so that the card slot 40 at the bottom end of the rotating ring block 36 is engaged with the card member 27. Tension and elasticity are detected through the tension sensor 39 at the bottom end of the rotating ring block 36. After the replacement is completed, the clamping block 31 no longer locks the moving block 25 through the third motor 33 and the reverse threaded rod 34. At this time, the moving plate 3 and the turntable 12 are moved through the first motor 6 and the first threaded rod 5, so that the yarn can be stretched. The detection is to stretch the yarn to a specified length at a constant speed and then release it. The force value during the stretching process is collected in real time through the tension sensor 39 at the bottom end of the rotating ring block 36. The elongation data is collected in real time through the first distance sensor 41 and the second distance sensor 43. By calculating the ratio of the maximum elongation of the yarn during the stretching process to the original length, the elastic elongation rate is obtained. After the stretching is completed, the yarn is no longer tightened through the first threaded rod 5 and the first motor 6. At this time, the moving block 25 and the card member 27 are reset. The moving block 25 is fixed again through the clamping block 31. The tension sensor 39 at the bottom end of the rotating ring block 36 is reset again through the fourth motor 37 and the second threaded rod 38. At this time, the card member 27 and the card slot 40 are engaged. Again, through the first threaded rod 5 and the first motor 6, the second support rod 11 and the turntable 12 at one end, the length of the yarn recovered after release is obtained through the first distance sensor 41 and the second distance sensor 43. Finally, by measuring the ratio of the length of the yarn recovered after release to the stretching length, the elastic recovery rate is obtained. Finally, these data are compared with the standard parameters to evaluate the elastic performance of the yarn. After the stretching detection is completed, by performing multiple repeated stretching and recovery cycles on the yarn, the elastic fatigue situation in actual use is simulated. After each cycle, the change in the elastic index of the yarn is measured. Finally, the degree of elastic attenuation after multiple cycles is analyzed to judge the elastic durability of the yarn. After the detection is completed, the user only needs to remove the yarn after this detection and replace it with a new yarn to be detected to continue the detection. This device is simple and convenient to operate, has a high degree of intelligence, can automatically complete the detection of high elastic performance, and does not require the user to operate repeatedly for a long time. It can not only reduce the workload of the user, but also quickly and accurately detect the high elastic performance of the electrostatic high elastic yarn, and can also improve production efficiency and product quality.Reduce production costs and quality risks.

By the fourth motor (37) and the second threaded rod (38), the swivel block (36), the tensile sensor (39), and the card slot (40) are lifted. Replace the card slot (40) at the bottom of the swivel block (36) with the tensile sensor (39) engaged. By the third motor (33) and the reverse threaded rod (34), the clamping block (31) no longer locks the moving block (25). At this time, by the first motor (6) and the first threaded rod (5), the moving plate (3) and the turntable (12) move to stretch the yarn. The force value during the stretching process is collected in real time by the tensile sensor (39) at the bottom of the swivel block (36).
