Description

Technical Field

[0001] This utility model relates to the field of twisting processing technology, specifically to a multi-strand twisting processing device for high-elastic polyester yarn. Background Technology

[0002] In the modern textile industry, high-elastic polyester yarn is widely used in clothing fabrics, home textiles, and industrial textiles due to its excellent elastic recovery, high strength, and abrasion resistance. Multi-strand twisting, a key process for improving the overall performance of high-elastic polyester yarn, tightly binds multiple strands, enhancing their strength and toughness, and optimizing the fabric's feel and appearance. Through proper twisting techniques, the stability of high-elastic polyester yarn during subsequent weaving processes can be effectively improved, meeting the diverse needs of different end products.

[0003] Reference patent (Publication No.: CN221218024U; Publication Date: 2024-06-25) discloses a polyester filament twisting device, belonging to the field of polyester production and processing technology. It includes: a processing table; a first motor fixedly installed at one end of the processing table; a feeding rack inside the processing table; the output end of the first motor fixedly connected to the feeding rack; a feeding roller fixedly installed on one side of the feeding rack; a fixing rod fixedly connected inside the processing table; a guide unit with a function of quickly threading the filament through holes fixedly installed at one end of the fixing rod; a receiving unit with an automatic receiving function on one side of the guide unit; a guide rod slidably inserted inside the receiving unit; and the guide unit includes a guide cylinder. Before twisting, workers can easily pass the polyester filament through the guide cylinder and fix it to the receiving roller for polyester twisting, avoiding wasting a lot of time on threading and saving manpower.

[0004] Based on the aforementioned patents, existing high-elastic polyester yarn multi-strand twisting processing devices typically employ simple fixed yarn guides to guide the multi-strand yarns. However, due to the lack of effective constraints on the yarn's movement path, the yarn is prone to shaking and tangling during processing. This shaking causes instability in the yarn's position upon entering the twisting area, resulting in the twisted yarn often not being evenly wound onto the take-up spool during winding. The yarn tends to accumulate in a certain area of ​​the take-up spool. Therefore, this invention provides a high-elastic polyester yarn multi-strand twisting processing device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a multi-strand twisting processing device for high-elastic polyester yarn. This device solves the problem that, due to the lack of effective constraint on the yarn's movement path, the yarn is prone to swaying and tangling during processing. The swaying of the yarn leads to instability in its position when entering the twisting area, and subsequently, the twisted yarn often cannot be evenly wound onto the take-up shaft during winding, resulting in the yarn easily accumulating in a certain area of ​​the take-up shaft.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-strand twisting processing device for high-elastic polyester yarn, comprising a mounting bracket, wherein a processing mechanism for multi-strand twisting of high-elastic polyester yarn is mounted on the mounting bracket, the processing mechanism comprising:

[0007] The guide assembly includes a mounting platform connected to the upper end of the mounting bracket via a drive assembly. Six sets of polyester filament rolls are mounted on the upper end of the mounting platform. A vertical rod is fixed to one side of each polyester filament roll at the edge of the mounting platform. First guide rings are evenly distributed on the inner wall of the vertical rod. An inclined rod is mounted at the top of the vertical rod. Second guide rings are evenly distributed on the inner wall of the inclined rod.

[0008] The dispersion component includes a support rod fixed to one side of the mounting bracket, a horizontal plate fixed to the top of the support rod, a guide shell disposed inside one end of the horizontal plate above the inclined rod, a guide tube rotatably connected to the upper end of the guide shell, and a positioning ring connected by a reciprocating component disposed at the center of the upper end of the horizontal plate.

[0009] Preferably, the drive assembly includes a motor mounted on the upper end of a mounting bracket, the mounting platform being mounted on the upper end of the motor, and the mounting platform being connected to the output end of the motor.

[0010] Preferably, positioning rods are uniformly fixed on the lower end face of the mounting platform, and an annular groove is provided on the upper end face of the mounting bracket to be slidably connected to the lower end of the positioning rods.

[0011] Preferably, the guide housing has a conical structure, and the lower end of the guide housing has an open structure, with a rubber ring fixed at the open edge of the lower end of the guide housing.

[0012] Preferably, the reciprocating assembly includes a U-shaped bracket fixed to the upper end of a horizontal plate, a pair of sliding rods fixed to the inner wall of the U-shaped bracket, a slider slidably connected to the outer wall of the sliding rods, a reciprocating lead screw rotatably connected to the inner wall of the U-shaped bracket, a positioning ring located at the upper end of the slider, and positioning wheels provided on both sides of the upper end of the slider located on the positioning ring.

[0013] Preferably, a winding shaft is provided on the upper end face of the horizontal plate on one side of the positioning ring, the guide tube has an arc-shaped structure, and the output end of the guide tube is aligned with the positioning ring.

[0014] Beneficial effects

[0015] This invention provides a multi-strand twisting processing device for high-elastic polyester yarn. Compared with the prior art, it has the following advantages:

[0016] Firstly, the first guide ring on the inner wall of the vertical rod and the second guide ring on the inner wall of the inclined rod provide initial guidance for the filaments drawn from the polyester filament spool, allowing the filaments to move along a predetermined path, reducing swaying and tangling, and ensuring the stability of the filaments when entering subsequent processing stages. This provides a good foundation for subsequent twisting operations. The guide shell has a conical structure with an open lower end and a rubber ring fixed at the edge, which can gather the six dispersed filaments together. The rubber ring acts as a buffer and protects the filaments, preventing them from being damaged by friction with the edge of the guide shell. The arc-shaped guide tube provides secondary guidance for the gathered filaments, allowing them to enter the positioning ring more accurately, further ensuring the positional accuracy of the filaments during the twisting process and improving the stability and quality of the twisting.

[0017] Secondly, the reciprocating screw of this invention drives the slider to slide on the slide bar, causing the positioning ring to reciprocate. After the six strands of yarn pass through the positioning ring, the twisted yarn is evenly wound on the take-up shaft, forming a tight and neat roll, avoiding accumulation on the take-up shaft. In addition, the positioning wheels on both sides of the positioning ring at the upper end of the slider play a role in positioning and guiding the yarn, preventing the yarn from falling off the positioning ring during the reciprocating motion, ensuring the stability and reliability of the twisting process, and avoiding production interruption caused by the yarn falling off the positioning ring.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a multi-strand twisting processing device for high-elastic polyester yarn, including a mounting bracket 1, on which a processing mechanism for multi-strand twisting of high-elastic polyester yarn is provided, the processing mechanism including:

[0025] The guide assembly includes a mounting bracket 1 with a mounting platform 201 connected to it via a drive assembly at its upper end. The mounting platform 201 has six sets of polyester filament rolls 204 at its upper end. A vertical rod 3 is fixed to one side of the polyester filament rolls 204 at the edge of the mounting platform 201. First guide rings 301 are evenly distributed on the inner wall of the vertical rod 3. An inclined rod 302 is provided at the top of the vertical rod 3. Second guide rings 303 are evenly distributed on the inner wall of the inclined rod 302.

[0026] High-elastic polyester yarn is wound on six sets of polyester yarn spools 204. After being drawn out from the polyester yarn spools 204, it passes through the first guide rings 301 evenly distributed on the inner wall of the vertical rod 3, and then through the second guide rings 303 evenly arranged on the inner wall of the inclined rod 302. The first guide rings 301 and the second guide rings 303 play a preliminary guiding role for the yarn drawn out from the polyester yarn spools 204, so that the yarn moves along a predetermined path, reducing the shaking and tangling of the yarn, and ensuring the stability of the yarn when it enters the subsequent processing stage.

[0027] The dispersion component includes a support rod 4 fixed on one side of the mounting bracket 1, a horizontal plate 401 fixed at the top of the support rod 4, a guide housing 402 located inside one end of the horizontal plate 401 above the inclined rod 302, a guide tube 404 rotatably connected to the upper end of the guide housing 402, and a positioning ring 504 connected by a reciprocating component at the center of the upper end of the horizontal plate 401.

[0028] In a preferred embodiment, the drive assembly includes a motor 2 mounted on the upper end of the mounting bracket 1, a mounting platform 201 mounted on the upper end of the motor 2 and connected to the output end of the motor 2, and positioning rods 202 uniformly fixed on the lower end face of the mounting platform 201. An annular groove 203 slidably connected to the lower end of the positioning rods 202 is opened on the upper end face of the mounting bracket 1. When the motor 2 starts, it drives the mounting platform 201 to rotate. The positioning rods 202 uniformly fixed on the lower end face of the mounting platform 201 slide in the annular groove 203 opened on the upper end face of the mounting bracket 1, playing a positioning and support role. The motor 2 drives the mounting platform 201 to rotate, providing power for the subsequent twisting operation. The cooperation between the positioning rods 202 and the annular groove 203 ensures the stability of the mounting platform 201 during rotation, prevents it from shifting, and ensures the smooth progress of the twisting process. The motor model is Y2-200L1-2Y.

[0029] In a preferred embodiment, the guide housing 402 has a conical structure, and the lower end of the guide housing 402 has an open structure, with a rubber ring 403 fixed at the open edge of the lower end of the guide housing 402.

[0030] In a preferred embodiment, the reciprocating assembly includes a U-shaped bracket 5 fixed to the upper end of a horizontal plate 401. A pair of sliding rods 502 are fixed to the inner wall of the U-shaped bracket 5. A slider 503 is slidably connected to the outer wall of the sliding rods 502. A reciprocating screw 501 is rotatably connected to the inner wall of the U-shaped bracket 5. A positioning ring 504 is located at the upper end of the slider 503. Positioning wheels 505 are provided on both sides of the upper end of the slider 503 located at the positioning ring 504. The reciprocating screw 501 rotates on the inner wall of the U-shaped bracket 5, causing the slider 503 to slide on the outer wall of the sliding rods 502, thereby causing the positioning ring 504 located at the upper end of the slider 503 to reciprocate. After the six strands of yarn pass through the positioning ring 504, the twisted yarn is evenly wound on the take-up shaft 6 to form a tight and neat roll.

[0031] The positioning wheels 505 located on both sides of the positioning ring 504 at the upper end of the slider 503 play a role in positioning and guiding the wire, preventing the wire from falling off the positioning ring 504 during reciprocating motion.

[0032] In a preferred embodiment, a winding shaft 6 is provided on the upper end face of the horizontal plate 401, located on one side of the positioning ring 504. The guide tube 404 has an arc-shaped structure, and the output end of the guide tube 404 is aligned with the positioning ring 504. The six strands of wire, after initial guidance, enter the guide housing 402. The guide housing 402 has a conical structure, with an open structure at the lower end and a rubber ring 403 fixed at the edge. After the wires are gathered from the lower opening of the guide housing 402, they are output through the arc-shaped guide tube 404. The output end of the guide tube 404 is aligned with the positioning ring 504. The guide housing 402 gathers the six dispersed wires together. The rubber ring 403 acts as a buffer and protects the wires, preventing the wires from being damaged by friction with the edge of the guide housing 402. The guide tube 404 provides secondary guidance for the gathered wires, making the wires enter the positioning ring 504 more accurately.

[0033] The guide tube 404 can rotate within the guide housing 402, and its movement is coordinated with the swing of the positioning ring 504.

[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0035] During operation, the high-elastic polyester yarn multi-strand twisting processing device winds the high-elastic polyester yarn onto six sets of polyester yarn spools 204 at the upper end of the mounting platform 201. The yarn drawn from the polyester yarn spools 204 first passes through the first guide rings 301 evenly distributed on the inner wall of the vertical rod 3, and then through the second guide rings 303 evenly arranged on the inner wall of the inclined rod 302. The first guide rings 301 and the second guide rings 303 provide initial guidance for the yarn, making it move along a predetermined path, reducing shaking and tangling, and ensuring stability when entering the subsequent processing stage.

[0036] Subsequently, the six strands of wire, after initial guidance, enter the guide housing 402 located above the inclined rod 302 inside one end of the horizontal plate 401 at the top of the support rod 4. The guide housing 402 is conical in shape, with an opening at the lower end and a rubber ring 403 fixed at the edge. It gathers the six scattered strands of wire. The rubber ring 403 buffers and protects the wire, preventing it from being damaged by friction with the edge of the guide housing 402. The gathered wire is output through the arc-shaped guide tube 404 rotatably connected at the upper end. The output end of the guide tube 404 is aligned with the positioning ring 504 connected to the center of the upper end of the horizontal plate 401 through the reciprocating assembly, which provides secondary guidance to the wire, making it enter the positioning ring 504 more accurately.

[0037] In the reciprocating assembly, the reciprocating lead screw 501 on the inner wall of the U-shaped bracket 5 rotates, causing the slider 503, which is slidably connected to the outer wall of the slide rod 502, to slide. This causes the positioning ring 504 at the upper end of the slider 503 to reciprocate. The positioning wheels 505 on both sides of the positioning ring 504 at the upper end of the slider 503 position and guide the yarn, preventing it from detaching from the positioning ring 504 during the reciprocating motion. After the six strands of yarn pass through the positioning ring 504, the twisted yarn is evenly wound onto the take-up shaft 6 on the upper end face of the horizontal plate 401, located on one side of the positioning ring 504, forming a tight and neat roll. At the same time, the motor 2 at the upper end of the mounting bracket 1 starts, driving the mounting table 201 to rotate. The positioning rods 202, which are evenly fixed on the lower end face of the mounting table 201, slide in the annular grooves 203 opened on the upper end face of the mounting bracket 1, playing a positioning and support role, ensuring the stable rotation of the mounting table 201, providing power for the twisting operation and ensuring the smooth progress of the process.
