Description

Technical Field

[0001] The invention relates to the technical field of yarn tension uniformity detection, in particular to a cotton and linen yarn tension uniformity detection device. Background Art

[0002] The seeds of cotton and castor are picked, dried, threshed by machine, and the seeds and cotton and linen parts are separated. They are then pressed by machine and spun into threads and cloth. When the cotton and linen yarn is spun into cloth, it needs to be transported and will be affected by tension during transportation. Tension refers to the pulling force acting on the axial direction of the yarn, which is manifested as the tension of the yarn. In production, the force level of cotton and linen yarn samples needs to be tested to prevent the cotton and linen yarn from breaking during textile transmission.

The sweater yarn is clamped and fixed, the sweater yarn is stretched by a displacement mechanism, and the tension is monitored in real time by a tension sensor. The detection process is easy to operate and the detection result is highly accurate. The above-mentioned related technologies have the following defects: when detecting the yarn, in order to ensure the uniformity of the yarn detection, pressure is applied to different positions of the yarn. However, during the detection, since the two ends of the yarn are fixed, when pressure is applied to different positions of the yarn, the yarn will produce different degrees of deformation. The existing detection equipment cannot ensure that the same pulling force is applied to the yarn due to the different degrees of yarn deformation at different positions of the yarn, thereby failing to ensure the uniformity of the detection.

[0015] In summary, the present invention includes the following beneficial technical effects:

[0016] 1. The present invention arranges a pressure damping ring, a damping block, a pull rope and an annular cavity disk. When the air pressure in the annular cavity disk increases, the two pressure damping rings are pushed closer to each other to apply pressure to the damping block. When the annular cavity disk rotates, the pressure damping ring is driven to rotate synchronously. The pressure damping ring pulls the damping block to rotate along with the pressure damping ring through the friction between the pressure damping ring and the damping block. The damping block pulls the movable frame and the tension wheel through the pull rope to apply tension to the yarn to be tested. When the resistance of the yarn to the tension wheel is equal to the friction between the pressure damping ring and the damping block, the damping block rotates relative to the pressure damping ring to stably generate maximum tension on the yarn. When the tension wheel changes its lateral position with the yarn, it is ensured that the tension of the tension wheel on the yarn is the friction between the pressure damping ring and the damping block, so that the tension applied to the yarn is the same when testing different positions of the yarn, thereby ensuring the uniformity of yarn tension detection.

[0017] 2. The present invention arranges a pressure vent pipe, a coaxial rod, an air pressure plugging disk and an adjusting threaded rod. The adjusting threaded rod is rotated to adjust the distance between the air pressure plugging disk and the outer end of the pressure vent pipe. This can control the maximum air pressure in the vertical vent pipe, the gas cavity ring and the annular cavity disk, change the pressure of the pressure damping ring on the damping block, control the friction between the pressure damping ring and the damping block, and control the tension on the yarn through the pull rope and the tension wheel.

[0018] 3. The present invention arranges a reciprocating screw rod, a meshing ring, a driven gear, an arcuate tooth plate and a driven gear ring. The driving gear drives the center rotating ring to rotate when meshing with the driven gear ring. The rotation of the center rotating ring drives the movable frame and the tension wheel to rotate around the yarn. The yarn can be tested for tension in different directions. When the center rotating ring rotates one circle, the arcuate tooth plate is driven to mesh with the driven gear once. When the driven gear drives the reciprocating screw rod to mesh with the meshing ring, it drives the center rotating ring and the tension wheel to move in a lateral direction. The tension wheel changes the force point of the yarn every time it applies tension around the yarn, thereby uniformly testing the yarn.

[0019] 4. The present invention sets a bending rod, a wire pressing nut and a wire clamping groove, separates the upper wire pressing nuts on both sides from the bending rod, puts the two ends of the yarn to be detected into the two wire clamping grooves respectively, and then engages the two wire pressing nuts with the bending rod, close to the two wire pressing nuts below, and presses and fixes the two ends of the yarn between them.

[0033] A torque motor 13 is fixed on the upper surface of the central rotating ring 3, one end of the single-ended hollow shaft 10 is fixed to the output end of the torque motor 13, and the other end of the single-ended hollow shaft 10 is rotatably plugged with a bent pipe 14, and the other end of the bent pipe 14 is connected and installed with the gas control structure 5. The torque motor 13 drives the annular cavity disk 11 to rotate through the single-ended hollow shaft 10.

[0034] The gas control structure 5 includes a gas cavity ring 51 and an inner sealing ring 52. The inner sealing ring 52 is rotatably inserted into the inner ring surface of the gas cavity ring 51. The inner sealing ring 52 is fixedly sleeved on the outer surface of the curved pipe 14. The gas cavity ring 51 is slidably sleeved on the outer surfaces of the two parallel struts 2. The upper surface of the gas cavity ring 51 is connected and installed with a vertical ventilation pipe 53. The upper end of the vertical ventilation pipe 53 is connected and installed with an air pump 55. The side of the vertical ventilation pipe 53 is connected and installed with an air pressure regulating structure 54. The air pump 55 inflates the gas cavity ring 51 through the vertical ventilation pipe 53, and then inflates the single-ended hollow shaft 10 and the annular cavity disk 11 through the curved pipe 14.

[0035] The air pressure regulating structure 54 includes a pressure vent pipe 541, a coaxial rod 542 and an air pressure plugging plate 543. The air pressure plugging plate 543 is slidably sleeved on the outer surface of the coaxial rod 542. The two ends of the air pressure plugging plate 543 are elastically connected to the two ends of the coaxial rod 542 respectively. The air pressure plugging plate 543 is slidably inserted into the interior of the pressure vent pipe 541. The pressure vent pipe 541 is fixedly connected to the vertical vent pipe 53.

The other end of the threaded rod 544 is rotated to penetrate the inner wall of the pressure vent pipe 541. The threaded rod 544 is rotated to adjust the distance between the air pressure blocking disk 543 and the outer end of the pressure vent pipe 541. The air pressure in the annular cavity disk 11, the gas cavity ring 51 and the vertical vent pipe 53 increases, and the air pressure blocking disk 543 is gradually pushed to move toward the outer end of the pressure vent pipe 541. When the air pressure blocking disk 543 moves out from the outer end of the pressure vent pipe 541, the maximum air pressure of the annular cavity disk 11, the gas cavity ring 51 and the vertical vent pipe 53 is limited.

[0036] A damping block 16 is slidably inserted inside the annular concave structure of the annular cavity disk 11. The damping block 16 is located between the two pressure damping rings 12. When the air pressure in the annular cavity disk 11 increases, the pressure damping ring 12 applies pressure to the damping block 16 under the push of the gas. When the annular cavity disk 11 rotates, the friction between the pressure damping ring 12 and the damping block 16 applies tension to the pull rope 9. At the same time, the friction between the pressure damping ring 12 and the damping block 16 is controlled by controlling the pressure on the pressure damping ring 12. The outer annular surface of the tension wheel 7 is annularly concave, and the outer annular surfaces of the two tension wheels 7 are in rolling contact, so that the yarn is pulled from the two tension wheels 7. When the yarn passes through the two tension wheels 7, the front and back sides of the damping block 16 are both convex structures. The end of the pull rope 9 located outside the center swivel 3 is fixed to the bottom surface of the damping block 16. The outer surface of the annular cavity disk 11 is rotatably sleeved with an outer cover ring 111, and the outer cover ring 111 is slidably sleeved on the outer surface of the pull rope 9. The outer cover ring 111 limits the position of the pull rope 9 entering the annular recessed structure of the annular cavity disk 11. When the resistance of the yarn to the tension wheel 7 is equal to the friction between the pressure damping ring 12 and the damping block 16, the damping block 16 rotates relative to the pressure damping ring 12 to generate maximum tension for yarn stability.

[0037] A reciprocating structure 17 is installed at one end of the stabilizing ring frame 4 away from the center rotating ring 3, and the other end of the reciprocating structure 17 is connected to the supporting main frame 1. A driven gear 19 is installed at one end of the reciprocating structure 17 close to the center rotating ring 3. The reciprocating structure 17 includes a reciprocating screw rod 171 and a meshing ring 172. The meshing ring 172 is threadedly sleeved on the outer surface of the reciprocating screw rod 171, and the meshing ring 172 is fixed to the supporting main frame 1. The stabilizing ring frame 4 is rotatably sleeved on the outer surface of the reciprocating screw rod 171, and the driven gear 19 is coaxially fixedly sleeved on the outer surface of the reciprocating screw rod 171.

[0038] An arc-shaped toothed plate 18 is fixed to the outer ring surface of the center rotating ring 3 , and the outer ring surface of the arc-shaped toothed plate 18 is tangent to the driven gear 19 . Every time the center rotating ring 3 rotates one circle, the arc-shaped toothed plate 18 meshes with the driven gear 19 once, driving the reciprocating screw rod 171 to rotate once and mesh with the meshing ring 172 .

[0039] A power torsion structure 20 is installed on the side of the stabilizing ring frame 4, and the power torsion structure 20 is connected to the outer ring surface of the center rotating ring 3. The power torsion structure 20 includes a power motor 201 and a driving gear 202. The power motor 201 is fixed to the stabilizing ring frame 4, and the driving gear 202 is coaxially fixed to the output end of the power motor 201. A driven gear ring 203 is meshed below the driving gear 202, and the driven gear ring 203 is coaxially fixedly sleeved on the outer surface of the center rotating ring 3. The power motor 201 drives the center rotating ring 3 to rotate through the meshing of the driving gear 202 and the driven gear ring 203. When the center rotating ring 3 rotates, it drives the tension wheel 7 to rotate around the yarn, constantly changing the pressure on the yarn.

[0040] A thread clamping structure 21 is coaxially installed at both ends of the supporting main frame 1. The thread clamping structure 21 includes a bending rod 211 and two wire pressing nuts 212. One end of the bending rod 211 is fixed to the supporting main frame 1, and the other end of the bending rod 211 is bent upward. The two wire pressing nuts 212 are threadedly sleeved on the end of the bending rod 211 away from the supporting main frame 1. A wire clamping groove 213 is provided on the upper end surface of the upwardly bent end of the bending rod 211. When fixing the yarn, the two ends of the yarn are respectively passed through the two wire clamping grooves 213, and the yarn is located between the two wire pressing nuts 212 on the upper and lower sides. The two upper wire pressing nuts 212 are rotated to engage with the bending rod 211 and approach the two lower wire pressing nuts 212 to clamp and fix the two ends of the yarn.

[0041] The working principle is as follows: the yarn is passed between the two tension wheels 7, the two ends of the yarn are fixed, and air is inflated into the annular cavity disk 11. After the air pressure in the annular cavity disk 11 increases, the two pressure damping rings 12 are pushed closer to each other to apply pressure to the damping block 16. The pressure damping ring 12 is driven to rotate synchronously during the rotation of the annular cavity disk 11. The pressure damping ring 12 pulls the damping block 16 to rotate with the pressure damping ring 12 through the friction between the pressure damping ring 12 and the damping block 16. The damping block 16 pulls the movable frame 6 and the tension wheel 7 through the pull rope 9 to apply tension to the yarn to be tested. When the resistance of the yarn to the tension wheel 7 is equal to the resistance of the pressure damping ring 12 to the damping block 16, the tension is applied to the yarn. When the friction force between the blocks 16 is generated, the damping block 16 rotates relative to the pressure damping ring 12, and the maximum tension is generated stably on the yarn. Then, the center swivel ring 3 drives the tension wheel 7 to rotate around the yarn when rotating, so that the tension of the yarn can be detected in different directions. When the center swivel ring 3 rotates one circle, it drives the arc-shaped tooth plate 18 to mesh with the driven gear 19 once, and controls the tension wheel 7 to move horizontally once, so that the tension wheel 7 changes the force point of the yarn once after applying tension every time it goes around the yarn. After changing the position, since the pressure between the pressure damping ring 12 and the damping block 16 remains unchanged, the tension wheel 7 can produce stable tension detection on the yarn.

[0042] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
