Description

Technical Field

[0001] This invention relates to the field of twisting device technology, and more specifically, to a twisting device and process for polyester sewing thread. Background Technology

[0002] Polyester sewing thread is a type of sewing thread made from polyester (polyethylene terephthalate, PET) fiber. Due to its comprehensive performance advantages, polyester sewing thread has become a mainstream choice in clothing, leather, and industrial fields, especially excelling in applications requiring high strength, weather resistance, and cost-effectiveness. The production process of polyester sewing thread requires the assistance of a twisting device to twist two or more strands into one.

[0003] According to the search, patent CN208055537U discloses a spinning device for textiles, including a base plate, a housing, and a turntable. A spinning base is fixedly supported at the middle of the top of the base plate by a second column. A U-shaped support frame is fixedly connected to the top of the base plate on one side of the spinning base by a first column. A take-up roller is detachably mounted on both ends of the U-shaped support frame by a first mounting seat and a second mounting seat. A housing is installed on the top of the base plate on the other side of the spinning base. A rotary motor is installed inside the drive compartment of the housing. The output shaft of the rotary motor passes through the housing and is fixedly connected to the turntable. A winding roller is installed on the turntable. Thread is evenly wound on the winding roller. The end of the thread away from the winding roller passes through the spinning base and is fixedly connected to the take-up roller. Mounting seats are fixedly connected to the outer sides of the grooves on both sides of the mounting block by springs. A slot matching the winding roller is provided at the middle of the outer side of the mounting seat, which facilitates the installation and removal of the winding roller and makes it easy to use.

[0004] Regarding the aforementioned technologies, existing twisting devices are typically in the above-described state. While they can twist polyester sewing thread, they rely on an unwinding roller for thread feeding and a take-up roller for take-up. After the unwinding roller finishes feeding, the operator needs to replace both the unwinding and take-up rollers. After replacement, the operator connects the thread segment from the unwinding roller to the take-up roller before restarting the device for twisting. Although this does not affect the overall operation, the switching process takes a considerable amount of time, resulting in the machine needing to stop for a significant amount of time after each twisting cycle for replacement, thus affecting the overall efficiency of the machine. Therefore, a twisting device and its process for polyester sewing thread are proposed. Summary of the Invention

[0005] To address the above problems, this invention provides a twisting device and process for polyester sewing thread, employing the following technical solution:

[0006] A twisting device for polyester sewing thread includes a main module and a replacement module. The main module includes a base plate, a platform and a frame are fixedly connected to the top of the base plate. The replacement module includes a movable switching component mounted on the platform, a rotating platform rotatably connected to the top of the base plate, and twelve movable mounting components. Eight of the movable mounting components are mounted on the movable switching component, and the other four are mounted on the rotating platform. Each movable mounting component on the movable switching component is connected to a feed roller, and each take-up roller on the rotating platform is equipped with a take-up roller. The outer surfaces of the four take-up rollers are provided with arc-shaped grooves. A replacement component is provided on the top of the base plate, connected to the rotating platform, and adapted to the movable switching component. The replacement component is located between the platform and the rotating platform. Multiple sets of auxiliary wheels are movably connected to the frame, and a drive component and a drive assembly are provided on the frame. The drive components are connected to each other, and the drive assembly is connected to two of the arc-shaped grooves.

[0007] Furthermore, the movable switching component includes an inner turntable rotatably connected inside the platform. A first motor is connected to the top of the base plate, and the output shaft of the first motor is fixedly connected to the bottom of the inner turntable. Two annular grooves are formed between the top of the platform and the top of the inner turntable. Four arc-shaped strips are slidably connected inside each of the two annular grooves. A switching gear is fixedly connected to the top of each of the eight arc-shaped strips. Two cross-shaped gears are rotatably connected to the top of the platform. The eight switching gears are movably connected to the outer surfaces of the two cross-shaped gears, and the outer surfaces of the two switching gears mesh with each other.

[0008] Furthermore, the active switching assembly also includes a connecting rod fixedly connected to the bottom of one of the cross-tooth discs, the bottom end of the connecting rod extending to the bottom of the shelf, and a connecting gear fixedly connected to the bottom end of the connecting rod.

[0009] Furthermore, the drive assembly includes a third motor fixedly connected to the front end face of the fixed frame. The output shaft of the third motor is fixedly connected to two steering rods. One end of each of the two steering rods is fixedly connected to an arc-shaped block. The two arc-shaped blocks are respectively movably connected inside two of the arc-shaped grooves.

[0010] Furthermore, the replacement component includes a four-way grooved wheel fixedly connected to the outer surface of the rotary table, a vertical rod rotatably connected to the top of the base plate, a drive disk fixedly connected to the top of the vertical rod, and the outer surface of the drive disk being movably connected to the outer surface of the four-way grooved wheel.

[0011] Furthermore, the replacement assembly also includes a small gear fixedly connected to the outer surface of the vertical rod, a second motor fixedly connected to the top of the base plate, and an incomplete gear fixedly connected to the output shaft of the second motor, the incomplete gear being adapted to the small gear and the connecting gear.

[0012] Furthermore, the movable mounting assembly includes a movable seat rotatably connected to the top of one of the switching gear discs, a hexagonal limiting rod fixedly connected to the top of the movable seat, the pay-off roller and the take-up roller movably sleeved on the outer surface of the hexagonal limiting rod, a threaded post fixedly connected to the top of the hexagonal limiting rod, a pressing nut threadedly connected to the threaded post, and the bottom of the pressing nut abutting against the top of the pay-off roller.

[0013] Furthermore, the arrangement assembly includes a strip groove formed on a fixed frame, a lifting block slidably connected inside the strip groove, a guide plate fixedly connected to the front end face of the lifting block, a connecting shaft fixedly connected to one side of the guide plate, two first mounting seats fixedly connected to the front end face of the fixed frame, a reciprocating wheel rotatably connected between the interiors of the two first mounting seats, a reciprocating groove formed on the outer surface of the reciprocating wheel, and one end of the connecting shaft movably connected inside the reciprocating groove.

[0014] Furthermore, the arrangement assembly also includes a worm gear fixedly connected to the top of the reciprocating wheel, and two second mounting seats fixedly connected to the front end face of the fixing frame. A worm is rotatably connected between the interiors of the two second mounting seats. The outer surface of the worm meshes with the outer surface of the worm wheel. One end of the worm and the outer surface of the output shaft of the third motor are both fixedly connected with bevel gears, and the outer surfaces of the two bevel gears mesh with each other.

[0015] A twisting process for polyester sewing thread includes the following steps:

[0016] S1. Twisting steps: Turn on the third motor and the first motor. The first motor will drive the inner turntable to rotate. The inner turntable drives two of the switching toothed discs to rotate through the arc strip to perform the twisting operation. The third motor will drive the take-up roller to rotate through the cooperation of the arc block and the arc groove. At the same time, the movable seat will rotate, so that the take-up roller can take up the twisted yarn segment.

[0017] S2. Switching steps: Turn on the second motor, which will drive the incomplete gear to rotate. The incomplete gear will drive the pinion, which will drive the vertical rod and drive disk to rotate 360 ​​degrees. The drive disk will drive the four-way groove wheel and the turntable to rotate 90 degrees, causing one take-up roller to disengage from the two arc blocks, while the two arc grooves of the other take-up roller will connect with the two arc blocks. Subsequently, the incomplete gear will drive the connecting gear, which will drive one of the cross-tooth discs to rotate through the connecting rod. When the cross-tooth disc rotates, it will drive the four switching discs to rotate 90 degrees. Through the meshing of the outer surfaces, the two cross-tooth discs will rotate 90 degrees, allowing the other two arc strips to enter the inner turntable. This will move the two new pay-off rollers to the designated positions, thus completing the switching. Simply pass the line segment through multiple sets of auxiliary wheels and guide plates and connect it to the new take-up roller.

[0018] S3. Replacement steps: Rotate the disassembly pressing nut, lift the pay-off roller and take-up roller upwards, and you can remove the pay-off roller and take-up roller from the hexagonal limit rod for replacement. After replacement, reinstall the pressing nut to fix it.

[0019] S4. Arrangement Steps: When the third motor is working, it will drive the worm gear to rotate through the meshing of two bevel gears. The worm gear will drive the worm wheel to rotate, and the worm wheel will drive the reciprocating wheel to rotate. The reciprocating wheel will push the connecting shaft through the reciprocating groove. The connecting shaft will drive the guide plate to perform reciprocating lifting and lowering operations. The guide plate will guide the wire segments, so that the wire segments can be neatly arranged on the take-up roller.

[0020] In summary, the present invention has the following beneficial technical effects:

[0021] (1) The present invention, through the setting of the active switching component, the active mounting component, the pay-off roller, the take-up roller, the replacement component and the drive component, enables the take-up roller and the pay-off roller to be switched by the replacement component. The operator only needs to perform the wiring step. After the wiring is completed, the device continues to perform the twisting operation. Subsequently, the pay-off roller and the take-up roller after the winding and unwinding are replaced, so that the twisting and replacement operations can be performed simultaneously. The time of the two steps overlaps, thereby improving the efficiency of the device.

[0022] (2) By setting up incomplete gears, connecting gears and pinions, the present invention enables the device to switch between take-up rollers and pay-off rollers by driving a single second motor, thereby making the two steps work together and the switching steps more seamless. No additional drive setting is required, reducing the cost of the device and making it easier for it to be widely used.

[0023] (3) The present invention, through the setting of reciprocating wheel, bevel gear, connecting shaft, worm and worm wheel, enables the sewing thread to be automatically sorted during the winding process, making the device more comprehensive. Attached Figure Description

[0039] The following is in conjunction with the appendix Figure 1-9 The present invention will be described in further detail below.

[0040] Please see Figure 1-9 A twisting device for polyester sewing thread includes a main module 100 and a replacement module 200. The main module 100 includes a base plate 110, with a platform 120 and a mounting frame 130 fixedly connected to the top of the base plate 110. The replacement module 200 includes a movable switching assembly 210 disposed on the platform 120, and a rotating platform 220 rotatably connected to the top of the base plate 110. The replacement module 200 also includes twelve movable mounting assemblies 230, eight of which are disposed on the movable switching assembly 210, and the other four are disposed on the rotating platform 220. Each of the four take-up rollers 240 is connected to the bottom plate 110. The take-up rollers 250 on the rotary table 220 are also equipped with take-up rollers 250. The outer surface of each of the four take-up rollers 250 is provided with an arc-shaped groove. A replacement component 260 is provided on the top of the bottom plate 110. The replacement component 260 is connected to the rotary table 220 and is adapted to the movable switching component 210. The replacement component 260 is located between the storage platform 120 and the rotary table 220. Multiple sets of auxiliary wheels 270 are movably connected to the fixed frame 130. A drive component 280 and a drive component 280 are provided on the fixed frame 130. The drive component 280 is connected to the drive component 280 and is connected to two of the arc-shaped grooves.

[0041] During use, the operator opens the drive assembly 280 and the movable switching assembly 210. The drive assembly 280 will drive one of the take-up rollers 250 and the movable mounting assembly 230 to rotate. The movable switching assembly 210 will drive the two unwind rollers 240 to rotate and perform the twisting operation, so that the take-up roller 250 can wind up the twisted yarn segment. When the unwind roller 240 has finished unwinding and the take-up roller 250 has finished winding, the replacement assembly 260 is opened. The replacement assembly 260 will first drive the rotary table 220 to rotate 90 degrees, so that one of the take-up rollers 250 is separated from the drive assembly 280 and the other take-up roller 250 is connected to the drive assembly 280. Subsequently, the replacement assembly 260 will drive the movable switching assembly 210, which will then drive... The unwinding roller 240 is displaced, causing two new unwinding rollers 240 to move to designated positions, thus completing the switching. Subsequently, the operator only needs to pass the thread segment through the arranging assembly 290 and connect it to the new take-up roller 250. The drive assembly 280 and the movable switching assembly 210 are then opened again, enabling the next round of twisting operation. At this time, the operator can replace the take-up roller 250 and the unwinding roller 240, allowing the twisting and replacement operations to be performed simultaneously. The time overlap of the two steps improves the efficiency of the device. When the drive assembly 280 is working, it will drive the arranging assembly 290, which will guide the thread segment so that the thread segment can be neatly arranged on the take-up roller 250.

[0042] The movable switching assembly 210 includes an inner turntable 211 rotatably connected inside the shelf 120. A first motor 213 is connected to the top of the base plate 110, and the output shaft of the first motor 213 is fixedly connected to the bottom of the inner turntable 211. Two annular grooves 212 are formed between the top of the shelf 120 and the top of the inner turntable 211. Four arc-shaped strips 214 are slidably connected inside each of the two annular grooves 212. Switching gears 215 are fixedly connected to the top of each of the eight arc-shaped strips 214. Two cross-shaped gears 216 are rotatably connected to the top of the shelf 120. The eight switching gears 215 are movably connected to the outer surfaces of the two cross-shaped gears 216, and the outer surfaces of the two switching gears 215 mesh with each other. The movable switching assembly 210 also includes a connecting rod 217 fixedly connected to the bottom of one of the cross-shaped gears 216. The bottom end of the connecting rod 217 extends to the bottom of the shelf 120, and a connecting gear 2 is fixedly connected to the bottom end of the connecting rod 217. 18. The drive assembly 280 includes a third motor 281 fixedly connected to the front end face of the fixed frame 130. The output shaft of the third motor 281 is fixedly connected to two steering rods 282. One end of each steering rod 282 is fixedly connected to an arc-shaped block 283. The two arc-shaped blocks 283 are movably connected inside two arc-shaped grooves. The replacement assembly 260 includes a four-way grooved wheel 261 fixedly connected to the outer surface of the rotary table 220. A vertical rod 262 is rotatably connected to the top of the base plate 110. A drive disk 264 is fixedly connected to the top of the vertical rod 262. The outer surface of the drive disk 264 is movably connected to the outer surface of the four-way grooved wheel 261. The replacement assembly 260 also includes a pinion 263 fixedly connected to the outer surface of the vertical rod 262. A second motor 265 is fixedly connected to the top of the base plate 110. An incomplete gear 266 is fixedly connected to the output shaft of the second motor 265. The incomplete gear 266 is adapted to the pinion 263 and the connecting gear 218.

[0043] When the third motor 281 and the first motor 213 are turned on, the first motor 213 will drive the inner turntable 211 to rotate. The inner turntable 211 drives two of the switching gear discs 215 to rotate via the arc-shaped bar 214, thereby performing the twisting operation. The third motor 281 will drive the take-up roller 250 to rotate via the cooperation of the arc-shaped block 283 and the arc-shaped groove. At the same time, the movable seat 231 will rotate, so that the take-up roller 250 can wind up the twisted yarn segment. When the unwinding roller 240 has finished unwinding and the take-up roller 250 has finished winding, the second motor 265 is turned on. The second motor 265 will drive the incomplete gear 266 to rotate. The incomplete gear 266 will drive the pinion 263. The pinion 263 will drive the vertical rod 262 and the drive disk 264 to rotate 360 ​​degrees. The drive disk 264 will drive the four-way grooved wheel 261 and the rotary table 220 to rotate 90 degrees, so that one of the take-up rollers can rotate. Roller 250 disengages from the two arc-shaped blocks 283, while the two arc-shaped grooves of another take-up roller 250 connect with the two arc-shaped blocks 283. Subsequently, the incomplete gear 266 drives the connecting gear 218, which drives one of the cross-tooth discs 216 to rotate via the connecting rod 217. When the cross-tooth disc 216 rotates, it drives the four switching discs 215 to rotate 90 degrees. Through the meshing of the outer surfaces, the two cross-tooth discs 216 rotate 90 degrees, allowing the other two arc-shaped strips 214 to enter the inner turntable 211, so that the two new pay-off rollers 240 move to the designated position, thus completing the switching. Afterwards, the operator only needs to pass the line segment through the multiple sets of auxiliary wheels 270 and the guide plate 292 and connect it to the new take-up roller 250. The third motor 281 and the first motor 213 are turned on again, thus realizing the next round of twisting operation.

[0044] The movable mounting assembly 230 includes a movable seat 231 rotatably connected to the top of one of the switching gear discs 215. A hexagonal limiting rod 232 is fixedly connected to the top of the movable seat 231. The pay-off roller 240 and the take-up roller 250 are movably sleeved on the outer surface of the hexagonal limiting rod 232. A threaded post is fixedly connected to the top of the hexagonal limiting rod 232. A pressing nut 233 is threadedly connected to the threaded post. The bottom of the pressing nut 233 abuts against the top of the pay-off roller 240.

[0045] Rotate and disassemble the pressing nut 233, lift the pay-off roller 240 and take-up roller 250 upwards, and you can remove the pay-off roller 240 and take-up roller 250 from the hexagonal limit rod 232 for replacement. After replacement, reinstall the pressing nut 233 to fix it, so that the twisting and replacement operations can be carried out at the same time.

[0046] The arrangement assembly 290 includes a strip-shaped groove formed on the fixing frame 130. A lifting block 291 is slidably connected inside the strip-shaped groove. A guide plate 292 is fixedly connected to the front end face of the lifting block 291. A connecting shaft 293 is fixedly connected to one side of the guide plate 292. Two first mounting seats 294 are fixedly connected to the front end face of the fixing frame 130. A reciprocating wheel 295 is rotatably connected between the interiors of the two first mounting seats 294. A reciprocating groove is formed on the outer surface of the reciprocating wheel 295. One end of the connecting shaft 293 is movably connected to... Inside the reciprocating groove, the arrangement assembly 290 also includes a worm gear 296 fixedly connected to the top of the reciprocating wheel 295. The front end face of the fixing frame 130 is fixedly connected to two second mounting seats 297. A worm 298 is rotatably connected between the interiors of the two second mounting seats 297. The outer surface of the worm 298 meshes with the outer surface of the worm gear 296. One end of the worm 298 and the outer surface of the output shaft of the third motor 281 are both fixedly connected to bevel gears 299. The outer surfaces of the two bevel gears 299 mesh with each other.

[0047] When the third motor 281 is working, it will drive the worm gear 298 to rotate through the meshing of two bevel gears 299. The worm gear 298 will drive the worm wheel 296 to rotate, and the worm wheel 296 will drive the reciprocating wheel 295 to rotate. The reciprocating wheel 295 will push the connecting shaft 293 through the reciprocating groove. The connecting shaft 293 will drive the guide plate 292 to perform reciprocating lifting and lowering operation. The guide plate 292 will guide the wire segments, so that the wire segments can be neatly arranged on the take-up roller 250, thereby improving the functionality of the device.

[0048] A twisting process for polyester sewing thread includes the following steps:

[0049] S1. Twisting Steps: Turn on the third motor 281 and the first motor 213. The first motor 213 will drive the inner turntable 211 to rotate. The inner turntable 211 drives two of the switching gear discs 215 to rotate through the arc strip 214 to perform the twisting operation. The third motor 281 will drive the take-up roller 250 to rotate through the cooperation of the arc block 283 and the arc groove. At the same time, the movable seat 231 rotates, so that the take-up roller 250 can take up the twisted yarn segment.

[0050] S2. Switching Steps: Turn on the second motor 265. The second motor 265 will drive the incomplete gear 266 to rotate. The incomplete gear 266 will transmit power to the pinion 263. The pinion 263 will drive the vertical rod 262 and the drive disk 264 to rotate 360 ​​degrees. The drive disk 264 will then transmit power to the four-way grooved wheel 261 and the rotary table 220 to rotate 90 degrees, causing one of the take-up rollers 250 to disengage from the two arc-shaped blocks 283, while the two arc-shaped grooves of the other take-up roller 250 will connect with the two arc-shaped blocks 283. Subsequently, the incomplete gear 266 will... The transmission connecting gear 218 drives one of the cross toothed discs 216 to rotate via the connecting rod 217. When the cross toothed disc 216 rotates, it will drive the four switching toothed discs 215 to rotate 90 degrees. Through the meshing of the outer surfaces, two cross toothed discs 216 rotate 90 degrees, thereby allowing the other two arc-shaped strips 214 to enter the inner turntable 211, so that the two new feed rollers 240 move to the designated position, thus completing the switching. It is only necessary to pass the line segment through multiple sets of auxiliary wheels 270 and guide plate 292 and connect it to the new take-up roller 250.

[0051] S3. Replacement steps: Rotate the disassembly pressing nut 233, lift the pay-off roller 240 and take-up roller 250 upwards, and the pay-off roller 240 and take-up roller 250 can be removed from the hexagonal limit rod 232 for replacement. After replacement, reinstall the pressing nut 233 to fix it.

[0052] S4. Arrangement Steps: When the third motor 281 is working, it will drive the worm gear 298 to rotate through the meshing of two bevel gears 299. The worm gear 298 will drive the worm wheel 296 to rotate. The worm wheel 296 will drive the reciprocating wheel 295 to rotate, so that the reciprocating wheel 295 will push the connecting shaft 293 through the reciprocating groove. The connecting shaft 293 will drive the guide plate 292 to perform reciprocating lifting and lowering operations. The guide plate 292 will drive the line segment to guide it, so that the line segment can be neatly arranged on the take-up roller 250.

[0053] The implementation principle of this invention is as follows: During use, the operator turns on the third motor 281 and the first motor 213. The first motor 213 drives the inner turntable 211 to rotate. The inner turntable 211 drives two switching gear discs 215 to rotate via the arc-shaped strip 214, thereby performing the twisting operation. The third motor 281 drives the take-up roller 250 to rotate via the cooperation of the arc-shaped block 283 and the arc-shaped groove. At the same time, the movable seat 231 rotates, so that the take-up roller 250 winds up the twisted yarn segment. When the unwinding roller 240 has finished unwinding and the take-up roller 250 has finished winding, the second motor 265 is turned on. The second motor 265 drives the incomplete gear 266 to rotate. The incomplete gear 266 will drive the pinion 263, which in turn drives the vertical rod 262 and the drive disc 264 to rotate 360 ​​degrees. The drive disc 264 will then drive the four-way grooved wheel 261 and the rotary table 220 to rotate 90 degrees, causing one of the take-up rollers 250 to disengage from the two arc blocks 283, while the two arc grooves of the other take-up roller 250 will connect with the two arc blocks 283. Subsequently, the incomplete gear 266 will drive the connecting gear 218, which, through the connecting rod 217, drives one of the cross gear discs 216 to rotate. When the cross gear disc 216 rotates, it will drive the four switching gear discs 215 to rotate 90 degrees, which is achieved through the external... The surface engagement causes the two cross-tooth discs 216 to rotate 90 degrees, allowing the other two arc-shaped strips 214 to enter the inner turntable 211. This moves the two new pay-off rollers 240 to their designated positions, completing the switchover. Afterward, the operator simply needs to pass the thread segment through the multiple sets of auxiliary wheels 270 and the guide plate 292 to connect it to the new take-up roller 250. The third motor 281 and the first motor 213 then restart, enabling the next round of thread twisting. At this point, the operator can rotate and disassemble the pressing nut 233, lifting the pay-off roller 240 and take-up roller 250 upwards to remove them from the hexagonal limit rod 232 for replacement. After replacement, the pressing nut 233 is reinstalled for fixation, allowing the twisting and replacement operations to be performed simultaneously. The overlapping of the two steps improves the efficiency of the device. When the third motor 281 is working, it will drive the worm gear 298 to rotate through the meshing of two bevel gears 299. The worm gear 298 will drive the worm wheel 296 to rotate, and the worm wheel 296 will drive the reciprocating wheel 295 to rotate. The reciprocating wheel 295 will push the connecting shaft 293 through the reciprocating groove. The connecting shaft 293 will drive the guide plate 292 to perform reciprocating lifting and lowering operations. The guide plate 292 will guide the wire segments, so that the wire segments can be neatly arranged on the take-up roller 250, improving the functionality of the device.
