Description

Technical Field

[0001] This invention belongs to the field of twisting machine structure design technology, specifically a compound twisting device. Background Technology

[0002] A doubling twister is an important piece of equipment in the textile industry used to twist single or multi-ply yarns into plied yarns. It is widely used in cotton spinning, wool spinning, chemical fiber spinning, and industrial textiles. Traditional doubling twisters typically place a hopper (or yarn cone) containing the yarn at a fixed position below the machine, and the twisting is completed by the high-speed rotation of the spindle. In actual production, the hopper needs to be changed frequently to meet the demands of continuous production.

[0003] The existing doubling twisters have the following main shortcomings: Low level of automation in material feeding: Most equipment still relies on manual handling and placement of material buckets one by one, which is labor-intensive, has long material change time, and seriously affects the overall production efficiency of the machine. Unreliable and poor adaptability of material hopper fixing: Traditional structures often use fixed brackets or simple clamps to limit the material hopper, which is difficult to adapt to material hoppers of different diameters and heights. In addition, vibration is easily generated during twisting, resulting in uneven yarn drying and increased breakage rate. Furthermore, the operation is cumbersome when changing the material hopper.

[0004] Insufficient yarn cleanliness: During the twisting process, fuzz, fly hair, or impurities are easily generated on the surface of the yarn. If these foreign objects are not removed in time, they will directly affect the subsequent weaving, dyeing, and finished product quality. However, existing equipment generally lacks online cleaning functions or has a complex cleaning structure with limited effectiveness.

[0005] In summary, existing double-twist yarn twisting devices still have significant shortcomings in continuous production, material barrel positioning and clamping, multi-specification adaptability, and yarn surface treatment. There is an urgent need for a composite double-twist yarn twisting device that is compact in structure, highly automated, stable in operation, and can effectively improve yarn quality.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] Please see Figure 1 , Figure 3 , Figure 7 and Figure 8 As shown, this embodiment of the invention provides a composite twisting device, specifically including a twisting machine 1. A feeding mechanism 2 is installed on the bottom platform of the twisting machine 1 for orderly feeding of multiple material bins 7. The feeding mechanism 2 is equipped with a clamping mechanism 4 for stabilizing the material bins 7 and a drive mechanism 5 for controlling the operation of the clamping mechanism 4. A cleaning mechanism 6 is installed on the twisting machine 1 for removing burrs from the outer side of the thread. Specifically, in this embodiment, the feeding mechanism 2 allows for the placement of multiple material bins, and its operation enables orderly feeding of these bins, resulting in convenient operation and high efficiency. The connecting mechanism 3 allows for the detachable installation of the feeding mechanism 2, facilitating subsequent disassembly and maintenance. Different models of accessories can be replaced according to the model of the material bins. The clamping mechanism 4, when the feeding mechanism 2 rotates, engages with the corresponding clamping mechanism 4 through the drive mechanism 5, thereby stabilizing the material bins during operation. By installing the cleaning mechanism 6, the lint on the outside of the yarn is scraped off during twisting and then pulled away and recycled, ensuring that the outside of the yarn is clean after twisting.

[0023] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the feeding mechanism 2 specifically includes a material tray 201. The bottom platform of the twisting machine 1 is provided with a material tray 201. The material tray 201 is provided with multiple feeding troughs 204. The multiple feeding troughs 204 are provided with material buckets 7. A rotating shaft 203 is installed at the center of the bottom of the material tray 201. The bottom of the rotating shaft 203 is rotatably connected to the twisting machine 1. A drive component for controlling the rotation of the material tray 201 is installed at the bottom of the rotating shaft 203. In this embodiment, the material tray 201 has a plum blossom-shaped structure, and the driving component is a stepper motor 202. The stepper motor 202 is detachably connected to the inner bottom of the twisting machine 1. The top output shaft of the stepper motor 202 is connected to the bottom of the rotating shaft 203 through a coupling. Through the plum blossom-shaped structure design of the material tray 201, an appropriate number of material feeding slots 204 are opened on the top edge of the material tray 201 to place multiple material buckets 7. At the same time, through the installation of the stepper motor 202, under the drive of an external controller, the stepper motor 202 rotates at a certain angle. The stepper motor 202 drives the rotating shaft 203 to control the rotation of the material tray 201, so that the material buckets 7 on the material tray 201 are fed in sequence, thereby improving production efficiency.

[0024] Please see Figure 5 and Figure 6 As shown, a connecting mechanism 3 is provided between the rotating shaft 203 and the material tray 201. The connecting mechanism 3 specifically includes a connecting groove 303, which is located at the center of the bottom of the material tray 201. The top of the rotating shaft 203 is slidably connected to the inside of the connecting groove 303. Both the top of the rotating shaft 203 and the inside of the connecting groove 303 have hexagonal structures. The opening of the connecting groove 303 allows the rotating shaft 203 to slide within the connecting groove 303, facilitating the disassembly and assembly of the material tray 201 from the top of the rotating shaft 203, enabling replacement and maintenance of the material tray 201. Simultaneously, the hexagonal structure design of the connecting groove 303 and the top of the rotating shaft 203 ensures that the rotating shaft 203 can stably drive the rotation of the material tray 201.

[0025] In a further optimized embodiment, protrusions 301 are installed on both sides of the top of the rotating shaft 203. The two protrusions 301 are symmetrically distributed, and one end of each protrusion 301 is slidably connected to the inside of the rotating shaft 203 via abutment springs 302. The connecting groove 303 has symmetrical grooves 304 inside, and the other ends of the two protrusions 301 abut against the inside of the grooves 304. Both the protrusions 301 and the grooves 304 are hemispherical structures. With the installation of the two protrusions 301, and in cooperation with the abutment springs 302, the two protrusions 301 can slide elastically with the sides of the rotating shaft 203. When the rotating shaft 203 is inserted into the connecting groove 303, the protrusions 301 are abutted and retracted. After the rotating shaft 203 is inserted into place, the protrusions 301 correspond to the grooves 304 inside the connecting groove 303. Under the abutment of the abutment springs 302, the protrusions 301 reset and insert into the grooves 304, thereby limiting the movement between the tray 201 and the rotating shaft 203. During disassembly, a certain pulling force is applied to the tray 201, causing the protrusion 301 to be pushed and contracted by the groove 304, thus separating the protrusion 301 from the groove 304 and allowing the tray 201 to be disassembled and removed.

[0026] Please see Figure 4 and Figure 7 As shown, the clamping mechanism 4 specifically includes clamping plates 402. Multiple clamping plates 402 are installed inside the material tray 201 in a ring-shaped, equidistant arrangement. Each clamping plate 402 is slidably connected to the inside of the material tray 201 via two return springs 403. One end of each clamping plate 402 has an arc-shaped structure and extends to the inner edge of the material discharge trough 204. A rubber pad 401 is installed at one end of each clamping plate 402. The installation of multiple clamping plates 402 clamps the material bucket 7 inside the material discharge trough 204. With the cooperation of the return springs 403, the clamping plates 402 are pulled, ensuring they are in a reset state inside the material tray 201. One end of each clamping plate 402 does not extend into the material discharge trough 204, facilitating the placement of the material bucket 7 inside the material discharge trough 204. When working on the designated material bucket 7, the corresponding clamping plate 402 is controlled to slide under the cooperation of the drive mechanism 5. The clamping plate 402 slides against the tension of the return spring 403, so as to abut against the side wall of the material bucket 7 inside the discharge trough 204, thereby achieving stable clamping of the material bucket 7 and facilitating stable wire feeding. The installation of the rubber pad 401 helps to increase the friction, so that the clamping plate 402 abuts tightly against the side wall of the material bucket 7, and is not prone to wear due to abutment.

[0027] Please see Figure 2 , Figure 6 and Figure 7As shown, the drive mechanism 5 specifically includes a movable groove 501. The bottom platform of the twisting machine 1 is provided with an annular movable groove 501. The movable groove 501 is concentric with the rotating shaft 203. A protruding plate 502 is fixedly connected inside the movable groove 501. The protruding plate 502 is located at the bottom of the twisting area of ​​the twisting machine 1. The bottom of the material tray 201 is provided with a sliding component for pushing and controlling the clamping plate 402. The sliding component is connected to the bottom of the clamping plate 402.

[0028] Specifically, in this embodiment, multiple sliding components extend into the movable groove 501. One of the sliding components abuts against the protruding plate 502. Through the opening of the movable groove 501, multiple sliding components at the bottom of the material tray 201 can rotate with the material tray 201 inside the movable groove 501. When the material tray 201 rotates at a certain angle, the corresponding sliding component abuts against the protruding plate 502, thereby driving the corresponding clamping plate 402 to slide. This allows the clamping plate 402 to clamp the side wall of the corresponding material bucket 7, enabling the twisting operation. After the twisting is completed, when the next material bucket 7 needs to be used, the material tray 201 rotates again, and another sliding component abuts against the protruding plate 502, clamping the material bucket 7. This process continues until the corresponding clamping plate 402 rotates with the material tray 201 to the working position, at which point the sliding component is abutted, allowing the clamping plate 402 to clamp the material bucket 7.

[0029] Please see Figure 6 and Figure 7 As shown, the sliding assembly specifically includes guide grooves 504 and driving blocks 505. The bottom of the tray 201 has multiple guide grooves 504 arranged in a ring. Driving blocks 505 are slidably connected inside each of the guide grooves 504. The top of each driving block 505 is connected to the bottom of the clamping plate 402 via a buffer assembly. The bottom of the driving block 505 extends to the outer side of the bottom of the guide groove 504, and a driving wheel 503 is rotatably connected to the bottom of the driving block 505. The driving block 505 extends into the interior of the movable groove 501. In this embodiment, one of the driving blocks 505 abuts against a convex plate 502, which has an isosceles trapezoidal structure. The guide grooves 504 allow for the sliding installation of the driving block 505. With the assistance of the buffer assembly, the top of the driving block 505 is connected to the clamping plate 402. When the material tray 201 rotates to the designated position, since the convex plate 502 is an isosceles trapezoidal structure, the drive wheel 503 will roll along the side wall of the convex plate 502, eventually driving the drive wheel 503 to move to one side, so that the drive wheel 503 drives the drive block 505 to slide in the guide groove 504, thereby pushing the clamping plate 402 to slide and clamp the material barrel 7. When the drive wheel 503 separates from the convex plate 502, the clamping plate 402 can be reset with the cooperation of the return spring 403, which facilitates the disassembly and assembly of the material barrel 7.

[0030] Please see Figure 7As shown, the buffer assembly includes a slide groove 506 and a buffer spring 507. Multiple clamping plates 402 have slide grooves 506 at their bottom centerlines, and the top of the driving block 505 is slidably connected to the inside of the slide groove 506. In this embodiment, both the slide groove 506 and the driving block 505 are "T"-shaped structures. A buffer spring 507 is provided inside the slide groove 506. One end of the buffer spring 507 is connected to the end of the slide groove 506, and the other end is connected to the side wall of the driving block 505. The elastic force of the buffer spring 507 is greater than the elastic force of the return spring 403. The opening of the slide groove 506 allows the driving block 505 to slide against the bottom of the clamping plate 402. Since both the slide groove 506 and the drive block 505 are "T" shaped structures, the drive block 505 and the slide groove 506 will not slip off. With the help of the buffer spring 507, the drive block 505 and the bottom of the clamping plate 402 can slide elastically. The elastic force of the buffer spring 507 is greater than that of the return spring 403. When the drive block 505 pushes against the buffer spring 507 and drives the clamping plate 402 to slide, the return spring 403 can be stretched, so that the clamping plate 402 can clamp the material barrel 7. After the material barrel 7 is clamped stably, the drive block 505 can still overcome the elastic force of the buffer spring 507 and slide in the slide groove 506, ensuring that the drive wheel 503 and the convex plate 502 are in contact and do not affect the continuous rotation of the material tray 201. At the same time, it makes the clamping plate 402 firmly clamp the connection and can also clamp material barrels 7 of different sizes.

[0031] Please see Figure 1 and Figure 8 As shown, the cleaning mechanism 6 includes a housing 602 and a mounting plate 601. The housing 602 is located at the bottom of the twisting machine 1. The housing 602 is mounted on top of the material bucket 7 in the working area via the mounting plate 601. A spring clip 604 is fixedly connected to the inner top of the housing 602. The spring clip 602 has a slotted bottom edge and a hollow, conical structure. A suction pipe 603 is connected to the outer side of the housing 602. The housing 602 is a hollow, columnar structure with openings at the top and bottom. In this embodiment, the housing 602 is installed using the mounting plate 601. The thread to be twisted is inserted into the spring clip 604 through the bottom of the housing 602 and finally exited from the top of the housing 602. During twisting, the conical structure at the bottom of the spring clip 604 scrapes away the lint on the outside of the thread. The suction pipe 603 connects to an external vacuum cleaner to remove the scraped lint, ensuring the thread is clean and tidy during the twisting process.

[0032] In use, the stepper motor 202 is first detachably installed on the bottom of the twisting machine 1. Then, the connecting groove 303 at the bottom of the designated material tray 201 is inserted into the top of the rotating shaft 203, allowing the material tray 201 to be easily disassembled and reassembled on the top of the rotating shaft 203, facilitating replacement and maintenance of the material tray 201. Simultaneously, the hexagonal structure design of the connecting groove 303 and the top of the rotating shaft 203 ensures that the rotating shaft 203 can stably drive the material tray 201 to rotate. Through the installation of the two protrusions 301, in cooperation with the anti-collision springs 302, the two protrusions 301 can elastically slide against the sides of the rotating shaft 203. When the rotating shaft 203 is inserted into the connecting groove 303, the protrusions 301 are retracted by the anti-collision. After the rotating shaft 203 is fully inserted, the protrusions 301 and the inside of the connecting groove 303... Corresponding to the groove 304, under the resistance of the spring 302, the protrusion 301 resets and inserts into the groove 304, thus limiting the distance between the tray 201 and the rotating shaft 203. During disassembly, a certain pulling force is applied to the tray 201, causing the protrusion 301 to retract due to the resistance of the groove 304, separating the protrusion 301 from the groove 304, allowing the tray 201 to be disassembled and removed. The plum blossom-shaped structure design of the tray 201 facilitates the opening of an appropriate number of material slots 204 on the top edge of the tray 201, enabling the placement of multiple material bins 7. Simultaneously, through the installation of the stepper motor 202, driven by an external controller, the stepper motor 202 rotates at a certain angle, driving the rotating shaft 203 to control the rotation of the tray 201, thus controlling the rotation of the material on the tray 201. The material buckets 7 are fed sequentially, improving production efficiency. Multiple clamping plates 402 are installed to clamp the material buckets 7 inside the feeding trough 204. With the cooperation of the return spring 403, the clamping plates 402 are pulled, ensuring they are in a reset state inside the material tray 201. One end of the clamping plate 402 does not extend into the feeding trough 204, facilitating the placement of the material buckets 7 inside. During subsequent work on a designated material bucket 7, the corresponding clamping plate 402 slides under the cooperation of the drive mechanism 5. The clamping plate 402 overcomes the pulling force of the return spring 403, sliding against the side wall of the material bucket 7 inside the feeding trough 204, achieving stable clamping of the material bucket 7 and facilitating stable wire feeding. The installation of rubber pads 401 increases friction. The force ensures that the clamping plate 402 makes a tight contact with the side wall of the material bucket 7, while minimizing wear caused by the contact. The opening of the movable groove 501 allows multiple sliding components at the bottom of the material tray 201 to rotate within the groove. When the material tray 201 rotates a certain angle, the corresponding sliding component contacts the protruding plate 502, driving the corresponding clamping plate 402 to slide. This allows the clamping plate 402 to clamp the corresponding side wall of the material bucket 7, enabling the twisting process. After twisting is complete, when the next material bucket 7 is needed, the material tray 201 rotates again, and another sliding component contacts the protruding plate 502, clamping the material bucket 7. This process continues until the corresponding clamping plate 402 rotates with the material tray 201 to the working position, at which point the sliding component is contacted.The clamping plate 402 clamps the material bucket 7. The guide groove 504 allows for the sliding installation of the drive block 505. With the assistance of the buffer assembly, the top of the drive block 505 connects to the clamping plate 402. When the material tray 201 rotates to a designated position, the drive wheel 503 rolls along the side wall of the convex plate 502 due to its isosceles trapezoidal structure. This ultimately drives the drive wheel 503 to move to one side, causing the drive block 505 to slide in the guide groove 504. This, in turn, pushes the clamping plate 402 to slide and clamp the material bucket 7. The drive wheel 503 and the convex plate 502... During separation, the clamping plate 402 can return to its original position with the help of the return spring 403, facilitating the disassembly and assembly of the material bucket 7. The opening of the sliding groove 506 allows the driving block 505 to slide against the bottom of the clamping plate 402. Both the sliding groove 506 and the driving block 505 have a "T"-shaped structure, preventing the driving block 505 from slipping off the sliding groove 506. Combined with the buffer spring 507, this facilitates elastic sliding between the driving block 505 and the bottom of the clamping plate 402. The elastic force of the buffer spring 507 is greater than that of the return spring 403, causing the driving block 505 to resist the buffer spring 507 and thus slide the clamping plate 402. When the material bucket 7 is clamped, the return spring 403 can be stretched, allowing the clamping plate 402 to hold the material bucket 7. After the material bucket 7 is clamped stably, the drive block 505 can still overcome the elastic force of the buffer spring 507 and slide in the slide groove 506, ensuring that the drive wheel 503 and the convex plate 502 are in contact and do not affect the continuous rotation of the material tray 201. At the same time, it makes the clamping plate 402 firmly clamp the connection and can also clamp material buckets 7 of different sizes. With the cooperation of the mounting plate 601, the housing 602 is installed. The housing 602 is a columnar structure with a hollow interior and openings at the top and bottom. The structure, through the cooperation of mounting plate 601, enables the installation of housing 602. The installation of spring clip 604 facilitates the insertion of the yarn to be twisted through the bottom of housing 602 into spring clip 604, and finally out from the top of housing 602. Spring clip 602 has a grooved bottom edge and a flexible, hollow, conical structure. During twisting, as the yarn moves, the conical structure at the bottom of spring clip 604 scrapes away the lint on the outside of the yarn. A vacuum cleaner hose 603 connects to an external vacuum cleaner to remove the scraped lint, ensuring the yarn remains clean and tidy during the twisting process.
