TECHNICAL FIELD

[0001] The application belongs to the technical field of yarn detection, and particularly relates to a wool sweater yarn tension detection device. BACKGROUND

[0002] Wool sweater yarn is the core material of a wool sweater, and its performance directly affects the quality and comfort of the finished garment. In the processing of wool sweater yarn, the tension thereof needs to be detected, and the data obtained through tension detection is convenient for analyzing the performance of the yarn and providing a basis for process improvement, so that a qualified wool sweater can be produced.

[0003] Patent No. CN218546364U discloses a sweater yarn tension detection device, which comprises a detection table, a fixed seat is fixedly installed on one side of the top of the detection table, a first yarn fixing mechanism is arranged on the top of the fixed seat, a movable seat is movably arranged on the other side of the top of the detection table, a second yarn fixing mechanism is arranged on the top of the movable seat, a displacement mechanism for adjusting the distance between the movable seat and the fixed seat is arranged on the detection table, a fixed plate is arranged on one side of the movable seat close to the fixed seat, the fixed plate is installed on the detection table, a tension sensor is arranged between the movable seat and the fixed plate, and a controller is further arranged on the detection table. The sweater yarn is clamped and fixed through the first yarn fixing mechanism and the second yarn fixing mechanism, the sweater yarn is stretched through the displacement mechanism, and the tension is monitored in real time through the tension sensor. The detection process is convenient, and the detection result is accurate.

[0004] However, the above technical solution still has the following disadvantages in actual application:

[0005] The two ends of the yarn are fixed, and then the yarn is stretched, and the tension is monitored in real time by the tension sensor, and the tension is displayed on the controller, so that the yarn tension is detected. Although the yarn tension can be detected in this way, in order to obtain the maximum tension value that the yarn can withstand, the yarn is usually stretched to its breaking point, and after the yarn breaks, the broken end of the yarn needs to be observed. The observation of the broken end of the yarn is an extension of the tension detection. By analyzing the breaking reason, the process parameters can be optimized reversely, the equipment state can be improved, and finally the yarn quality and production efficiency can be improved. When the yarn breaks, the broken end will bounce up, which may cause the yarn to wind around the surrounding parts or the yarn end to curl, so that it is difficult for the worker to observe the broken end of the yarn, and the further analysis of the breaking reason of the yarn is affected.

[0024] 2. The wool sweater yarn tension detection device provided by the present application utilizes the stabilizing assembly, so that the broken end of each yarn placed on the placement table can be attached by the adhesive tape, thereby stabilizing the yarn and avoiding the situation that the yarn is easily offset due to external force when placed on the placement table, and then the yarn is messy, and the staff compares and analyzes the yarn, which causes confusion.

[0025] 3. The wool sweater yarn tension detection device provided by the present application utilizes the scraping assembly. When the placement table is placed on a sufficient number of yarns, and the staff completes the observation and analysis of the broken end of the yarn, the adhesive tape and the yarn attached by the adhesive tape can be scraped off from the placement table, thereby realizing the cleaning of the yarn on the upper surface of the placement table, avoiding the situation that the yarn is difficult to be removed from the placement table due to being attached by the adhesive tape, and then affecting the subsequent use of the placement table.

[0048] Specifically, in use, the existing yarn tension detection device fixes both ends of the yarn, then stretches the yarn, simultaneously monitors the tension in real time through the tension sensor 42, and displays the tension on the controller, so as to achieve the effect of detecting the yarn tension. Although this way can realize the detection of the yarn tension, in general, in order to obtain the limit tension value that the yarn can bear, the yarn is stretched to its breaking point, and after the yarn breaks, the breaking end of the yarn needs to be observed. The observation of the breaking end of the yarn is an extension of the tension detection. Through the analysis of the breaking reason, the process parameters can be optimized reversely, the equipment state can be improved, and finally the yarn quality and production efficiency can be improved. However, when the yarn breaks, the breaking end of the yarn will bounce up, which may cause the yarn to be wound on the surrounding parts or the yarn end to be curled, so that it is difficult for the worker to observe the breaking end of the yarn, and the further analysis of the breaking reason of the yarn is affected.

[0049] Therefore, in order to solve the above problems, in use, both ends of the yarn to be detected are respectively placed at the grooves 46 on the winding rollers 45 on both sides, then the threaded rod four 55 is driven to rotate by the motor twelve 53, the threaded block 56 and the pressing column 57 are driven to descend, the pressing column 57 penetrates through the through hole on the winding roller 45 and extends into the groove 46, the groove plate four 54 is driven to slide by the cylinder three 52, and one end of the yarn is pressed in the groove 46 by the pressing column 57, so that the two ends of the yarn are tightly fixed, and both ends of the yarn penetrate through the ring formed by the two limiting rings 47.

[0050] Then the motor nine 41 drives the threaded rod 6 to rotate, drives the slide column 7 to slide in the groove plate 2, makes the two winding rollers 45 away from each other, and the yarn is stretched, and the tension sensor 42 monitors the tension in real time, and the tension value is displayed on the display screen, so that the tension of the yarn is detected.

[0051] When the yarn is broken, the motor ten 44 on both sides is started to drive the winding roller 45 to rotate, the winding roller 45 winds the yarn, the broken end of the yarn approaches the limiting ring 47, when the broken end of the yarn is in the limiting ring 47, the slide column 7 is driven to slide and the broken end of the yarn approaches, then the pressing column 57 is reset so that it no longer presses the yarn, at the same time, the motor eleven 50 drives the bidirectional threaded rod three 49 to rotate, the two adjusting rods 48 are away from each other, and the cylinder two 43 drives the scraping ring 51 to descend, the inner circle of the scraping ring 51 is attached to the outer circle surface of the winding roller 45, the yarn wound on the winding roller 45 is scraped off, at the same time, the broken end of the yarn also falls down due to the support of the limiting ring 47, at this time, the two broken ends of the yarn are close to each other and are placed on the placement table 9, the worker can easily observe the broken end of the yarn, so that the yarn winding on the surrounding parts or the yarn end curling caused by the broken end of the yarn bouncing up is avoided, and the worker can easily observe the broken end of the yarn, which affects the further analysis of the broken end of the yarn.

[0052] And usually, in order to improve the accuracy of the detection result, a plurality of yarns are detected in sequence, so that the motor thirteen 59 drives the threaded rod five 58 to rotate, the placement table 9 slides on the workbench 1, the position of the placement table 9 is adjusted, the position of the yarn falling on the placement table 9 is changed, and the plurality of broken yarns are placed on the placement table 9 in horizontal arrangement, so that the worker can compare and analyze the plurality of broken yarns, which is beneficial to further improve the accuracy of the detection result.

[0062] Specifically, in the above embodiment, although the yarn broken end can be attached to the placement table 9 by the adhesive tape 11, when the placement table 9 is placed on a sufficient number of yarns, the yarns need to be removed from the placement table 9 before the placement table 9 can be used again. However, since the yarns are attached by the adhesive tape 11, it is difficult to remove them from the placement table 9, thereby affecting the subsequent reuse of the placement table 9.

[0063] Therefore, in order to solve the above problems, when the placement table 9 is placed on a sufficient number of yarns and the staff completes the observation and analysis of the yarn broken end, the scraper 5 bottom can be moved along the upper surface of the placement table 9 by rotating the threaded rod six 60 driven by the motor four 17, so as to scrape off the adhesive tape 11 and the yarns attached by the adhesive tape 11, thereby realizing the cleaning of the yarns on the upper surface of the placement table 9, avoiding the situation that the yarns are attached by the adhesive tape 11, it is difficult to remove them from the placement table 9, thereby affecting the subsequent reuse of the placement table 9.

[0064] Work principle: the yarn to be detected is respectively placed at the groove 46 on the winding roller 45 on both sides, then the threaded rod four 55 is driven to rotate by the motor twelve 53, the threaded block 56 and the pressing column 57 are driven to descend, the pressing column 57 penetrates through the through hole on the winding roller 45 and extends into the groove 46, at the same time, the slot plate four 54 is driven to slide by the cylinder three 52, the yarn end is pressed in the groove 46 by the pressing column 57, so that the yarn ends are tightly fixed, and the yarn ends penetrate through the circular ring composed of two limiting rings 47; then the threaded rod one 6 is driven to rotate by the motor nine 41, the sliding column 7 is driven to slide at the slot of the slot plate one 2, the two winding rollers 45 are away from each other, so that the yarn is stretched, at the same time, the tension sensor 42 monitors the tension in real time, and the tension value is displayed on the display screen, so that the tension detection of the yarn is realized; when the yarn is broken, the motor ten 44 on both sides is started to drive the winding roller 45 to rotate, the winding roller 45 winds the yarn, and the broken end of the yarn approaches the limiting ring 47, when the broken end of the yarn is at the limiting ring 47, the sliding column 7 is driven to slide and the broken end of the yarn approaches, then the pressing column 57 is reset so that it no longer tightly presses the yarn, at the same time, the bidirectional threaded rod three 49 is driven to rotate by the motor eleven 50, the two adjusting rods 48 are away from each other, the cylinder two 43 drives the scraping ring 51 to descend, the inner circle of the scraping ring 51 is attached to the outer circle surface of the winding roller 45, the yarn wound on the winding roller 45 is scraped off, at the same time, the broken end of the yarn also falls down due to the loss of support of the limiting ring 47, at this time, the two broken ends of the yarn are close to each other and are placed on the placement table 9, the staff can easily observe the broken end of the yarn, so that the yarn winding on the surrounding parts or the yarn end curling due to the rebound of the broken end of the yarn after breaking is avoided, the staff can easily observe the broken end of the yarn, and the subsequent further analysis of the yarn breaking reason is affected; and, usually, in order to improve the accuracy of the detection result, a plurality of yarns are detected in turn, so that the placement table 9 slides on the workbench 1 by the threaded rod five 58 driven to rotate by the motor thirteen 59, the position of the placement table 9 is adjusted to change the position of the yarn falling on the placement table 9, so that the plurality of broken yarns are placed on the placement table 9 in horizontal arrangement, thereby facilitating the staff to compare and analyze the plurality of broken yarns, and being beneficial to further improve the accuracy of the detection result.The adhesive tape 11 is sleeved on the rotating shaft 21 in a roll, and the end of the adhesive tape 11 is pulled out and passes through the gap between the clamping rods 19. When the yarn is placed on the placement table 9, the motor 29 drives the bidirectional threaded rod 30 to rotate, so that the two adjacent clamping rods 19 are close to each other, and the adhesive tape is clamped. Then the cylinder 39 drives the blade plate 38 to move, and the blade end of the blade plate 38 cooperates with the connecting plate 22 to cut the adhesive tape 11. Then the motor 16 drives the groove plate 26 to rotate by 90 degrees, so that the adhesive surface of the cut adhesive tape 11 faces downward, and since the two yarn broken ends placed on the placement table 9 are close and aligned with the adhesive tape 11, the motor 13 drives the connecting rod 12 and the connecting rod 14 to rotate, so that the cut adhesive tape 11 is lowered until the clamping rod 19 is attached to the surface of the placement table 9. Then the motor 32 drives the threaded rod 33 to rotate, so that the threaded plate 18 slides on the sliding rod 34, and drives the pressure roller 35 to approach the adhesive tape 11, and the adhesive tape 11 is pressed on the placement table 9. At this time, the adhesive tape is preliminarily stabilized. Then the motor 27 drives the bidirectional threaded rod 28 to rotate, so that the two groove plates 31 are away from each other, and the adhesive tape 11 is separated from the clamping rod 19. Then the motor 23 drives the threaded rod 24 to rotate, so that the pressure roller 35 moves along the surface of the adhesive tape 11, and under the action of the spring 37, the pressure roller 35 is closely attached to the surface of the adhesive tape 11, and the adhesive tape 11 is compacted at each position. Then the groove plate 26 is reset, and the end of the adhesive tape 11 between the blade plate 38 and the connecting plate 22 can be clamped again by the upper clamping rod 19, so that the adhesive tape 11 is again between the clamping rods 19. The above operation can be repeated again, so that the broken end of each yarn placed on the placement table 9 can be attached by the adhesive tape 11, and the yarn is stabilized. When the placement table 9 is placed on a sufficient number of yarns, and the staff completes the observation and analysis of the broken end of the yarn, the motor 17 drives the threaded rod 60 to rotate, so that the bottom of the scraper 5 moves along the upper surface of the placement table 9, and the adhesive tape 11 and the yarn attached by the adhesive tape 11 are scraped off, thereby realizing the cleaning of the yarn on the upper surface of the placement table 9, avoiding the difficulty in removing the yarn from the placement table 9 due to the attachment of the yarn by the adhesive tape 11, and thereby affecting the subsequent use of the placement table 9.
