Description

Technical Field

[0001] The present invention relates to the technical field of textile detection equipment, and in particular to a yarn tensile strength detection device for producing super-soft knitting yarn. Background Art

[0002] During the production process, the performance of yarn needs to be tested. Tensile strength is one of the performance indicators of yarn. When the existing yarn tensile strength detection device is in use, the stretching distance of the device is limited. Therefore, for some yarns, it is difficult to detect their maximum stretching value, and therefore it is impossible to obtain the tensile strength of the yarn. At the same time, the efficiency of the existing device in repeatedly stretching the yarn is too slow, making it difficult for the device to quickly detect the fatigue value of the yarn (the yarn elasticity disappears and cannot be restored to its original state). Moreover, after the yarn breaks, the yarn will move due to the force at the time of breakage, and will be entangled and moved, making it difficult to remove from the device.

[0003] To this end, we propose a yarn tensile testing device for ultra-soft knitting yarn production to solve the above problems. Summary of the Invention

[0009] As another technical solution, the side walls of the movable roller and the second fixed roller are both provided with corresponding fixed wire grooves, and the inner walls of the fixed wire grooves are fixedly provided with barbed protrusions.

[0010] As another technical solution, the power structure includes a first threaded rod, the top end of the fixed base is fixedly connected to a driver, the output end of the driver is fixedly connected to a threaded sleeve rod, the threaded sleeve rod passes through the inner wall of the fixed groove and extends to the inner side of the fixed groove, the first threaded rod and the threaded sleeve rod are threadedly connected, the bottom end of the first threaded rod is fixedly connected to a fixing ring, the fixing ring is rotatably sleeved on the rotating shaft, and the fixing ring is slidably connected to the inner wall of the fixed groove.

[0011] As another technical solution, a connecting groove is provided at the top of the fixed groove, and a fixed shaft is rotatably connected to the inner wall of the connecting groove. The fixed shaft passes through the inner wall of the connecting groove and extends to the outside of the fixed shell.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1.

At the same time, when the yarn is wound around the second fixed roller and the movable roller, the rotating plate will move outward, so that the yarn is evenly spread on the second fixed roller and the movable roller, and fixed to the fixed groove, thereby preventing the yarn from piling up and winding.

[0017] 2. In the present invention, as the rotating plate rotates, the movable roller can be reciprocated up and down, thereby continuously stretching the yarn wound around the movable roller and the second fixed roller until the yarn is fatigued and cannot return to its original shape. At this time, the tensile fatigue value of the yarn can be obtained. Fatigue detection can be performed during the tensile detection process, thereby improving the detection efficiency and enabling a more comprehensive detection of the yarn's tensile resistance.

[0018] 3. In the present invention, the first fixed roller is rotated by rotating the threaded sleeve, and the yarn is wound onto the first fixed roller, thereby further increasing the stretching distance of the device. At the same time, after the yarn breaks, the broken yarn can also be wound onto the first fixed roller, thereby preventing multiple groups of yarns from being entangled together under the action of the force at the time of breakage, making it difficult to remove the yarn from the device.

DETAILED DESCRIPTION

[0028] Reference Figures 1-8 A yarn tensile testing device for producing ultra-soft knitting yarn comprises a fixed base 1, a fixed housing 2 is fixedly mounted on the top of the fixed base 1, a fixed slot 4 is formed on the fixed housing 2, a power structure is mounted on the fixed slot 4, a first fixed roller 11 is rotatably mounted on the side wall of the fixed housing 2, a force detector is fixedly mounted on the first fixed roller 11, the force detector can detect the force when the yarn is stretched, and when the yarn breaks, the force detected by the force detector becomes zero, at which time the control terminal automatically records the stretched distance, thereby obtaining the maximum value of the yarn stretching, so as to facilitate the judgment of the yarn's tensile resistance;

[0029] A tensile detection structure 5 is installed on the fixed housing 2. The tensile detection structure 5 includes a fixed plate 51 slidably connected to the fixed housing 2. The side wall of the fixed plate 51 is rotatably connected to a rotating shaft 56. The rotating shaft 56 extends to the inner side of the fixed groove 4 and is rotatably connected to the power structure. A fixed gear 57 is fixedly sleeved on the rotating shaft 56. The inner wall of the fixed groove 4 is fixedly connected to a fixed rack 55 matching the fixed gear 57, that is, the fixed gear 57 can mesh with the fixed rack 55. A second threaded rod 59 is slidably connected to the rotating shaft 56. The second threaded rod 59 passes through the fixed plate 51 and is fixedly connected to the rotating plate 52. A threaded block 58 is fixedly connected to the side wall of the fixed plate 51. The threaded block 58 is threadedly connected to the second threaded rod 59. The side wall of the rotating plate 52 is fixedly connected to a second fixed roller 53.

[0030] The two ends of the yarn are fixed to the first fixed roller 11 and a second fixed roller 53 respectively. When the rotating shaft 56 moves downward, the fixed gear 57, the fixed plate 51, the rotating plate 52 and other structures move accordingly. When the fixed gear 57 moves to the fixed rack 55, the fixed gear 57 will mesh with the fixed rack 55. At this time, the movement of the fixed gear 57 will cause it to rotate, driving the rotating shaft 56 to rotate accordingly. The second threaded rod 59 and the rotating plate 52 rotate together, winding the yarn onto the second fixed roller 53 and the moving roller 61, extending the distance that the device can stretch the yarn, and avoiding the inability to detect the yarn's tensile strength due to insufficient length of the device. At the same time, when the second threaded rod 59 rotates, under the action of the threaded block 58, the second threaded rod 59 will move outward, driving the rotating plate 52, the second fixed roller 53 and other structures to move outward together, so that when the yarn is wound around the second fixed roller 53 and the moving roller 61, it can be evenly spread on the second fixed roller 53 and the moving roller 61 without being entangled together;

[0031] A fatigue detection structure 6 is installed on the rotating plate 52. The fatigue detection structure 6 includes a moving groove 62 opened on the rotating plate 52. A moving block 67 is slidably connected between the inner walls of the moving groove 62. The side wall of the moving block 67 is rotatably connected to a moving roller 61. A distance detector and a force sensor are installed on the moving roller 61. The distance detector and the force sensor are both existing equipment, so their working principles are not described in detail. The distance detector can detect the distance moved by the second fixed roller 53, and the force sensor detects the force between the yarn and the moving roller 61. When the yarn is fatigued, that is, it cannot recover after stretching, the distance between the moving roller 61 and the second fixed roller 53 is too short. The force acting on the reciprocating screw 63 will be reduced to zero. At this time, the control terminal will record the data of the distance detector to obtain the fatigue value of the yarn, and the moving roller 61 corresponds to the second fixed roller 53. The inner wall of the moving groove 62 is rotatably connected to the reciprocating screw rod 63. The reciprocating screw rod 63 passes through the moving block 67 and the inner wall of the moving groove 62 and extends to the outside of the rotating plate 52. The moving block 67 is mechanically matched with the reciprocating screw rod 63. The end face of the reciprocating screw rod 63 is fixedly connected to the connecting gear 64. The side wall of the fixed plate 51 is fixedly connected to a connecting rod 65 whose position corresponds to the connecting gear 64. The connecting rod 65 is fixedly connected to a connecting rack 66 that matches the connecting gear 64.

[0032] As the rotating plate 52 rotates, the moving roller 61, the reciprocating screw rod 63 and the connecting gear 64 rotate accordingly. When the connecting gear 64 rotates to the connecting rack 66, the connecting gear 64 rotates under the action of the connecting rack 66, driving the reciprocating screw rod 63 to rotate as well, so that the moving block 67 mechanically matched with the reciprocating screw rod 63 can move up and down, driving the moving roller 61 to move up and down together, thereby repeatedly stretching the yarn wound around the moving roller 61 until the yarn cannot be restored. The control terminal records the stretched distance.

[0033] The side walls of the movable roller 61 and the second fixed roller 53 are each provided with a corresponding fixed groove 54. The inner wall of the fixed groove 54 is fixedly provided with a barbed protrusion, thereby fixing the yarn in the fixed groove 54. The yarn fixed in the fixed groove 54 will not fall out of the fixed groove 54.

[0034] The power structure includes a first threaded rod 9, the top of the fixed base 1 is fixedly connected to the driver 7, the output end of the driver 7 is fixedly connected to the threaded sleeve 8, the threaded sleeve 8 penetrates the inner wall of the fixed groove 4 and extends to the inner side of the fixed groove 4, the first threaded rod 9 and the threaded sleeve 8 are threadedly connected, and the bottom end of the first threaded rod 9 is fixedly connected to a fixing ring 510, which is rotatably sleeved on the rotating shaft 56 and is slidably connected to the inner wall of the fixed groove 4. Therefore, the fixing ring 510 and the first threaded rod 9 will not rotate with the threaded sleeve 8;

[0035] After the driver 7 is started, its output end drives the threaded sleeve 8 to rotate. Under the action of the thread, the first threaded rod 9 moves downward, pushing the fixing ring 510 and the rotating shaft 56 to move downward together;

[0036] A connecting groove 13 is formed at the top of the fixed groove 4. A fixed shaft 12 is rotatably connected to the inner wall of the connecting groove 13. The fixed shaft 12 passes through the inner wall of the connecting groove 13 and extends to the outside of the fixed housing 2. The first fixed roller 11 is fixedly sleeved on the fixed shaft 12. A connecting worm gear 14 is fixedly sleeved on the fixed shaft 12. A connecting worm 15 meshing with the connecting worm gear 14 is fixedly sleeved on the threaded sleeve 8. The end face of the fixed shaft 12 is threadedly connected to a limit block 10.

[0037] When the threaded sleeve 8 rotates, the connecting worm 15 fixedly sleeved on the threaded sleeve 8 rotates accordingly, causing the connecting worm wheel 14 meshing with the connecting worm 15 to rotate together, so that the fixed shaft 12 and the first fixed roller 11 also rotate, and the yarn is wound onto the first fixed roller 11, further stretching the yarn. At the same time, after the yarn is broken, the rotation of the first fixed roller 11 can wind up the broken yarn, thereby preventing multiple groups of yarns from being entangled with each other and difficult to remove.

[0038] A mounting bracket is fixedly mounted on the side wall of the fixed housing 2, and an operating screen 3 is rotatably connected to the mounting bracket. The device can be activated through the operating screen 3, and the detected data will be displayed on the operating screen 3. A damping structure is fixedly mounted at the connection between the mounting bracket and the operating screen 3. The damping structure is a kind of damper, which prevents the operating screen 3 from rotating when it is not actively adjusted.

[0039] A control terminal is placed inside the fixed housing 2. The control terminal is an existing device that is connected to the operation screen 3, force sensor and other structures to control and calculate these structures.

[0040] During use of the present invention, the two ends of the yarn are first fixed to the first fixed roller 11 and the second fixed roller 53 respectively, and then the driver 7 is started. After the driver 7 is started, its output end drives the threaded sleeve 8 to rotate. Under the action of the thread, the first threaded rod 9 moves downward, pushing the fixed ring 510 and the rotating shaft 56 to move downward together. When the rotating shaft 56 moves downward, the fixed gear 57, the fixed plate 51, the rotating plate 52 and other structures move accordingly, thereby stretching the yarn;

[0041] When the fixed gear 57 moves to the fixed rack 55, the fixed gear 57 will mesh with the fixed rack 55. At this time, the movement of the fixed gear 57 will cause it to rotate, driving the rotating shaft 56 to rotate accordingly. The second threaded rod 59 and the rotating plate 52 rotate together, winding the yarn onto the second fixed roller 53 and the movable roller 61, extending the distance that the device can stretch the yarn, and avoiding the inability to detect the tensile strength of the yarn due to insufficient length of the device. At the same time, when the second threaded rod 59 rotates, under the action of the threaded block 58, the second threaded rod 59 will move outward, driving the rotating plate 52, the second fixed roller 53 and other structures to move outward together, so that when the yarn is wound onto the second fixed roller 53 and the movable roller 61, it can be evenly spread on the second fixed roller 53 and the movable roller 61 without being entangled together;

[0042] At the same time, when the threaded sleeve 8 rotates, the connecting worm 15 fixedly sleeved on the threaded sleeve 8 rotates accordingly, causing the connecting worm wheel 14 meshing with the connecting worm 15 to rotate together, so that the fixed shaft 12 and the first fixed roller 11 also rotate, and the yarn is wound onto the first fixed roller 11, further stretching the yarn. At the same time, after the yarn is broken, the rotation of the first fixed roller 11 can wind up the broken yarn, preventing multiple groups of yarns from being entangled with each other and difficult to remove. When the yarn breaks, the control terminal will record the length of the yarn stretching, thereby obtaining the yarn's tensile strength value;

[0043] Moreover, as the rotating plate 52 rotates, the moving roller 61, the reciprocating screw 63 and the connecting gear 64 rotate accordingly. When the connecting gear 64 rotates to the connecting rack 66, the connecting gear 64 will rotate under the action of the connecting rack 66, driving the reciprocating screw 63 to rotate as well, so that the moving block 67 mechanically matched with the reciprocating screw 63 can move back and forth up and down, driving the moving roller 61 to move back and forth up and down together, thereby repeatedly stretching the yarn wrapped around the moving roller 61 until the yarn cannot be restored, and the control terminal records the stretched distance.
