Description

Technical Field

[0001] This invention relates to the technical field of nylon filament twisting, and in particular to a twisting device for nylon filament. Background Technology

[0002] Nylon yarn is a type of textile fabric, which comes in various types such as monofilament, plied yarn, and specialty yarn. Compared to the luster of silk, nylon yarn fabrics have a poorer luster, feeling as if they are coated with a layer of wax. When you rub the fabric back and forth with your hands, you can feel the friction between the fabrics. During the processing of nylon yarn, a twisting device is used to twist the nylon yarn. In the existing technology, the nylon yarn twisting device uses the combination of scattered holes and concentrated holes to allow the yarns extending from the four feed spools to be taken in and combined together, achieving the effect of dispersed insertion and then concentrated extension. By setting a twisting spindle, the gathered yarns can be intertwined and merged into a single yarn, achieving the effect of winding and merging. In the current technology for twisting nylon yarn, only one group of nylon yarns can be twisted at a time, which results in low twisting efficiency. Furthermore, after twisting one group of nylon yarns, it is necessary to remove the wound and twisted nylon yarns and restore the nylon yarns to be twisted in the storage area before twisting the next group of nylon yarns. This operation is quite cumbersome and therefore has room for improvement. Summary of the Invention

Each inner frame 18 is set for each turntable 9. A first rotating rod 19 rotates through one end of the inner wall of the inner frame 18. One end of the first rotating rod 19 extends out of the inner frame 18 and is connected to a winding rod 20. A first screw 21 is rotatably inserted into the threaded groove at one end of the winding rod 20. A second limiting plate 22 is fixedly sleeved on one end of the first screw 21.

The lead wire structure includes a traction bar 51 connected to the side of the turntable 9. The traction bar 51 is positioned corresponding to the sleeve rod 11. A second traction wheel 52 is installed at one end of the traction bar 51. During twisting, firstly, the nylon filament bobbin to be twisted is fitted onto the sleeve rod 11. The first screw on the first limiting plate 12 is rotated and inserted into the threaded groove at the top of the sleeve rod 11 to limit the fitted nylon filament bobbin. Next, the take-up drum is fitted onto the take-up rod 20. The second screw 21 on the second limiting plate 22 is rotated and inserted into the threaded groove at the end of the take-up rod 20. Then, the bidirectional motor 39 in the mounting sleeve 38 is started, driving the first vertical rod 40 and the second vertical rod 42 to rotate. The third gear 41 at the top of the first vertical rod 40 drives the first rotating ring 5 on the top ring 4 to rotate. The first rotating ring 5 drives the transmission rod 13 and the first gear 14 to rotate as a whole. Furthermore, the rotating column 8 and turntable 9 are driven to rotate via pulley 15 and belt 16, thereby simultaneously twisting multiple sets of nylon filaments. At the same time, the fourth gear 43 at the bottom of the second vertical rod 42 drives the second rotating ring 17 to rotate, and the second rotating rod 24 is driven to rotate via the second gear 23. In conjunction with the first bevel gear 25 and the second bevel gear 26, the first rotating rod 19 is driven to rotate. This drives the winding rod 20 and the winding drum to rotate as a whole, thereby automatically winding the twisted nylon filaments. The rotation of the second rotating rod 24 drives the reciprocating screw 29 to rotate via the third bevel gear 35, the fourth bevel gear 36 and the fourth rotating rod 37. The screw sleeve 30 drives the nylon filaments passing through the traction ring 31 to move back and forth on the rotating reciprocating screw 29, thereby uniformly winding the twisted nylon filaments.

[0018] See Figures 6-9 The traction structure includes two connecting strips 27 connected to the inner frame 18, a fixed box 28 between the two connecting strips 27, a reciprocating screw 29 at one end of the fixed box 28, a third driving structure between the reciprocating screw 29 and the third rotating rod 34, an end block 32 at one end of the reciprocating screw 29, a limiting rod 33 connected between the end block 32 and the fixed box 28, a screw sleeve 30 sleeved on the limiting rod 33 and the reciprocating screw 29, and a traction ring 31 on the screw sleeve 30. The third drive structure is fixedly sleeved on the third bevel gear 35 that rotates and inserts into the fixed box 28. One end of the reciprocating screw 29 is connected to the fourth rotating rod 37 that rotates and inserts into the fixed box 28. The fourth bevel gear 36 is sleeved on the fourth rotating rod 37. The fourth bevel gear 36 and the third bevel gear 35 are meshed together. A wire gathering structure is set on the top of the fixed box 28. The rotation of the second rotating rod 24 drives the reciprocating screw 29 to rotate through the third bevel gear 35, the fourth bevel gear 36 and the fourth rotating rod 37. The screw sleeve 30 drives the nylon yarn passing through the traction ring 31 to move back and forth on the rotating reciprocating screw 29, so as to uniformly wind up the twisted nylon.

[0019] See Figures 1-5The support structure includes a central rod 44 connected to the middle of the turntable 9, a base 45 set at the bottom of the central rod 44, a support rod 46 connected to the middle of the bottom of the base 45, a support block 47 set at the bottom of the support rod 46, the support block 47 is hemispherical, and multiple fixing frames 48 are evenly spaced on the side of the base 45. Two rotating shafts 49 rotate through the fixing frames 48, and a first traction wheel 50 is fixedly sleeved in the middle of each rotating shaft 49. The yarn gathering structure includes an L-shaped rod 53 connected to the fixed box 28. The L-shaped rod 53 extends to a gathering coil 54 located at one end below the abutment block 47. During yarn twisting, each nylon filament passes through the corresponding first traction wheel 50 and through the gathering coil 54. When the turntable 9 drives the nylon filaments to rotate, it can drive multiple nylon filaments in each group to twist at the gathering coil 54. Each nylon filament is pressed tightly against the arc-shaped surface of the abutment block 47. Thus, during yarn twisting, the abutment block 47 can "press" the nylon filaments at the twisting point, making the twisting between each group of nylon filaments more compact and improving the quality of the yarn twisting work.

[0020] The implementation principle of a twisting device for nylon filaments according to an embodiment of the present invention is as follows: First, the nylon filament bobbin to be twisted is fitted onto the sleeve rod 11. The first screw on the first limiting plate 12 is rotated and inserted into the threaded groove at the top of the sleeve rod 11 to limit the nylon filament bobbin. Next, the take-up bobbin is fitted onto the take-up rod 20. The second screw 21 on the second limiting plate 22 is rotated and inserted into the threaded groove at the end of the take-up rod 20. Then, the nylon filament to be twisted on the nylon filament bobbin passes around the corresponding second traction wheel 52 to avoid mutual interference between each group of nylon filaments during the twisting process. Furthermore, multiple nylon filaments in each group pass through the coil 54, and each nylon filament... The nylon filaments are all tightly attached to the arc-shaped surface of the abutment block 47. Then, each group of nylon filaments passing through the traction ring 31 is wound onto the take-up drum on the corresponding take-up rod 20. Then, the bidirectional motor 39 in the mounting sleeve 38 is started, driving the first vertical rod 40 and the second vertical rod 42 to rotate. The third gear 41 at the top of the first vertical rod 40 drives the first rotating ring 5 on the top ring 4 to rotate. The first rotating ring 5 drives the transmission rod 13 and the first gear 14 to rotate as a whole, and drives the rotating column 8 and the turntable 9 to rotate through the pulley 15 and the belt 16, thereby twisting multiple groups of nylon filaments at the same time. At the same time, the fourth gear 43 at the bottom of the second vertical rod 42 drives the second rotating ring 17 to rotate. The second gear 23 drives the second rotating rod 24 to rotate, which in turn drives the first rotating rod 19 to rotate in conjunction with the first bevel gear 25 and the second bevel gear 26. This drives the take-up rod 20 and the take-up drum to rotate as a whole, automatically winding up the twisted nylon yarn. The rotation of the second rotating rod 24, through the third bevel gear 35, the fourth bevel gear 36 and the fourth rotating rod 37, drives the reciprocating screw 29 to rotate. The screw sleeve 30 drives the nylon yarn passing through the traction ring 31 to move back and forth on the rotating reciprocating screw 29, thereby uniformly winding up the twisted nylon. During the operation, the rotation of the second rotating rod 24, through the third bevel gear 35, the fourth bevel gear 36 and the fourth rotating rod 37, drives the reciprocating screw 29 to rotate. The screw sleeve 30 drives the nylon yarn passing through the traction ring 31 to move back and forth on the rotating reciprocating screw 29, thereby uniformly winding up the twisted nylon. The four bevel gears 36 and the fourth rotating rod 37 drive the reciprocating screw 29 to rotate. The screw sleeve 30 drives the nylon yarn passing through the traction ring 31 to move back and forth on the rotating reciprocating screw 29, so as to evenly wind up the twisted nylon. In addition, when the turntable 9 drives the nylon yarn to rotate, it can drive multiple nylon yarns in each group to twist at the coil 54. Each nylon yarn is close to the arc surface of the abutment block 47. In this way, the abutment block 47 can play a "tightening" role at the twisting point of the nylon yarn, making the twisting between each group of nylon yarns more compact and improving the quality of the twisting work. This is how the twisting work of nylon yarn is realized.

[0021] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
