Description

Technical Field

[0001] This invention relates to the field of cashmere yarn twisting technology, specifically to a high-performance anti-mite cashmere yarn twisting device and its production process. Background Technology

[0002] To achieve mite-proof properties in cashmere yarn, a padding process is typically used during the yarn finishing stage. First, the cashmere yarn is immersed in a prepared mite-proof solution, ensuring full saturation and complete penetration. Then, the yarn is dried, allowing the effective components of the solution to remain within the yarn and bond firmly with the cashmere fibers, resulting in effective mite protection. The twisting device in cashmere yarn is a specific application of the yarn twisting mechanism. Its core function is to apply twist to the yarn through mechanical rotation, enhancing yarn strength, improving structural stability, and physical properties. The working principle of the twisting mechanism is to use rotational motion to twist the fiber strip or yarn around its own axis, forming a twist that fixes the longitudinal connection between fibers. This process requires two necessary conditions: tension and twist. Under spinning tension and twisting, the fibers in cashmere yarn undergo intense inward and outward transfer. When the fiber ends are squeezed out during this transfer and detach from other fibers, they are no longer pressed back into the yarn body due to a lack of centripetal force and tension, thus remaining on the yarn surface and forming fuzz. The scales on the surface of cashmere fibers are easily detached during twisting friction. When the yarn passes through some rough channels, the existing fuzz is easily scraped and stretched, and fibers already embedded in the yarn body may also be scraped out, leading to further deterioration and increase in fuzz on the yarn. The fuzz extending from the yarn surface forms a layer of fluff barrier, making it difficult for anti-mite liquid to effectively and evenly penetrate and adhere to the main fibers inside the yarn. Furthermore, uneven fuzz distribution can lead to different areas of the yarn having different capacities for the solution, resulting in excessive or insufficient local adhesion, affecting the consistency of the yarn's anti-mite performance. To address this, we propose a high-performance anti-mite cashmere yarn twisting device and production process. Summary of the Invention

[0003] The purpose of this invention is to provide a high-performance anti-mite cashmere yarn twisting device and production process to solve the problems mentioned in the background art.

A synchronous belt is installed between the two synchronous pulleys. The turntable has through holes for the yarn to pass through. Two rotating shafts are symmetrically rotatably installed on the turntable. Each rotating shaft is fitted with a cleaning ring for cleaning the hairiness on the surface of the yarn.

[0005] Preferably, two wedge blocks are symmetrically slidably installed inside the turntable, with each wedge block sliding towards the center of the turntable. Each wedge block is fixedly connected to the inner wall of the turntable with a first spring. Several limiting strips are slidably installed on each rotating shaft. One side of each limiting strip is fixedly connected to the inner wall of the corresponding cleaning ring, and the other side is set as an inclined surface. A top rod is vertically slidably installed inside each rotating shaft. The upper end of each top rod cooperates with the inclined surface of the corresponding limiting strip, and the lower end cooperates with the inclined surface of the corresponding wedge block.

[0006] Preferably, an internal gear ring is fixedly installed on each of the frames, and a gear that meshes with the internal gear ring is fixedly installed on the upper end of each of the rotating shafts.

[0007] Preferably, the rotation direction of the turntable is the same as the rotation direction of the yarn twisting, and the rotation direction of the shaft and the cleaning ring is opposite to the rotation direction of the yarn twisting.

[0008] Preferably, two wedge-shaped bars are symmetrically slidably installed inside the turntable. Each wedge-shaped bar has a stop bar fixedly installed on one side for limiting the wedge-shaped bar. Each wedge-shaped bar is fixedly connected to the inner wall of the turntable with a second spring. Each wedge-shaped bar has a sleeve fixedly installed on it. Each sleeve has a brush roller for removing lint adhering to the cleaning ring.

[0009] Preferably, a torsion spring is fixedly connected between the top inner wall of each brush roller and the top of the corresponding sleeve, a screw is vertically slidably installed inside each brush roller, each screw is located inside the corresponding sleeve, a spiral groove that cooperates with the screw is provided on the inner wall of each sleeve, and a pressure sensing plate for detecting the friction force on the surface of the cleaning ring is fixedly installed at the bottom of each sleeve.

[0010] Preferably, a dust collection mechanism is fixedly installed on one side of the frame, and an outer ring is fixedly installed at the suction end of the dust collection mechanism. An inner ring, which is rotated by the turntable, is rotatably installed inside the outer ring. The inner ring is provided with a plurality of suction ports for extracting feathers.

[0011] Preferably, a number of magnetic blocks are fixedly installed at the bottom of the yarn bobbin and the bottom of the machine frame, and each pair of corresponding magnetic blocks are magnetically attracted to each other.

[0012] Preferably, each of the cleaning rings is made of a highly elastic, wear-resistant polyurethane material, and its surface is roughened.

[0013] A production process for high-performance mite-resistant cashmere yarn specifically includes the following steps: S1. Select suitable cashmere raw materials for washing, sorting, and combing to remove coarse hair, dander, and impurities; S2. Dyeing and finishing the cashmere raw materials, and adding finishing oil to increase fiber cohesion and eliminate static electricity; S3. Use a carding machine to card the fiber raw material after carding, and then further stretch and twist the carded fiber sliver on a roving frame to make roving packages. S4. Use a spinning machine to further draft and twist the roving to form a fine yarn with the required strength and basic twist. Then combine several single yarns on a spinning machine. S5. Twist the combined yarn on a twisting device and remove excess hairs from the twisted yarn to make the yarn surface smoother. S6. Immerse the twisted cashmere yarn in the prepared anti-mite solution to allow the solution to penetrate the yarn, and then dry the yarn to retain the effective components of the anti-mite solution in the yarn.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention utilizes a third motor to drive a turntable, causing the shaft and cleaning ring to rotate in a circular motion while simultaneously rotating on their own axis. Loose fuzz will fall off due to friction, while firmly attached fuzz will be twisted back into the yarn along the direction of yarn rotation. This effectively cleans the fuzz on the yarn surface. When there is more fuzz in the yarn, the turntable rotates faster, the diameter of the cleaning ring is expanded, the distance between the two cleaning rings decreases, and the pressure on the yarn gradually increases. The faster the rotation speed of the cleaning ring, the stronger the cleaning ability. Conversely, if there is less fuzz in the yarn, the turntable rotates slower, and the cleaning ability decreases, preventing excessive friction on the yarn that could cause wear or new fuzz. The cleaning ability can be effectively adjusted according to the actual amount of fuzz in the yarn, making the yarn surface smoother and facilitating the penetration of subsequent anti-mite liquid. 2. This invention utilizes a wedge block to drive a stop bar, causing the wedge bar to slide along with the brush roller. The distance between the brush roller and the cleaning ring remains constant. As the cleaning ring rotates, it rubs against the brush roller, which brushes off the lint adhering to the surface of the cleaning ring and keeps the surface rough. This prevents lint from adhering to the surface of the cleaning ring or from becoming smooth due to friction with the yarn, which would affect the cleaning effect. At the same time, the friction force of the cleaning ring on the brush roller will drive the screw to rotate to a certain extent, causing the screw to slide upward. When the cleaning ring wears to a certain extent, the screw will press against the pressure sensing plate, prompting the operator to replace the cleaning ring to maintain a good cleaning effect.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-11 This invention provides a technical solution: a high-performance anti-mite cashmere yarn twisting device, comprising a frame 1, a bushing 2 for placing yarn rolls rotatably mounted at the bottom of the frame 1, a guide wire hole 3 for guiding the yarn inside the bushing 2, a yarn bobbin 4 for limiting the yarn roll rotatably mounted on the bushing 2, a plurality of magnetic blocks 5 fixedly mounted at the bottom of the yarn bobbin 4 and the bottom of the frame 1, with each pair of corresponding magnetic blocks 5 magnetically attracted to each other, and a guide wire ring 6 for limiting the yarn fixedly mounted on the frame 1. Two guide rollers 7 for limiting the yarn are rotatably mounted on the upper part of the frame 1. A first motor 8 for driving the two guide rollers 7 to rotate is fixedly mounted on the frame 1. An electric shaft 9 for winding the yarn is rotatably mounted on the top of the frame 1. A second motor 10 is fixedly mounted on the top of the frame 1. A rotating drum 11 is fixedly mounted on the output end of the second motor 10. The rotating drum 11 is provided with a reciprocating screw groove 12 for limiting the yarn. First, the yarn roll is placed on the bushing 2, and a winding spindle is installed on the electric shaft 9. One end of the yarn is then wound according to... Figure 2The yarn, as shown by the dotted line, enters through the wire hole 3 at the top of the bushing 2 and exits through the wire hole 3 at the bottom of the bushing 2. Then, the yarn passes through the wire ring 6 and is sequentially inserted into the slots of the two wire rollers 7. Finally, the end of the yarn is wound onto the take-up spindle on the electric shaft 9. After starting the equipment, the first motor 8 drives one of the wire rollers 7 to rotate. The two wire rollers 7 rotate synchronously via the belt drive mechanism on the frame 1. The electric shaft 9 then drives the take-up spindle to take up the yarn, and the second motor 10 drives the drum 11 to rotate. Through the reciprocating groove 12 on the drum 11, which limits the yarn, the yarn will reciprocate and slide on the electric shaft 9 for winding. The yarn is evenly wound on the take-up spindle to prevent it from tangling at a single point. As the electric shaft 9 winds the yarn, the yarn on the yarn roll is continuously pulled out and moves along the guide hole 3 inside the bushing 2. At the same time, the bushing 2 will rotate continuously, and the magnetic block 5 at the bottom of the yarn bobbin 4 is attracted by the magnetic force of the magnetic block 5 at the bottom of the frame 1, so that the yarn bobbin 4 and the yarn roll remain stationary. The pulled-out yarn will rotate while moving in a circle along the yarn bobbin 4, so that the yarn is twisted. The rotation amplitude of the rotating yarn is limited after passing through the guide ring 6, so that the yarn is not easy to fall off the guide roller 7. The yarn between the two guide rollers 7 will maintain a straight line movement, which facilitates the subsequent detection and removal of hairiness.

[0019] A photoelectric hairiness detector 13 for detecting yarn hairiness is fixedly installed on the frame 1 (the photoelectric hairiness detector is a known existing structure; its working principle is that when a light source illuminates the yarn, the hairiness on the yarn surface produces diffuse reflection, thereby changing the amount of light blocking in the yarn. The instrument indirectly determines the total amount of hairiness by detecting the change in light flux; this invention will not elaborate further). A third motor 14 is fixedly installed on the frame 1. The output power of the third motor 14 is proportional to the amount of hairiness detected by the photoelectric hairiness detector 13. A turntable 17 is rotatably installed on the frame 1. Synchronous pulleys 15 are fixedly installed at both the output end of the third motor 14 and the lower end of the turntable 17. A synchronous belt 16 is installed between the two synchronous pulleys 15 for transmission. The turntable 17 is provided with a mechanism for the yarn to pass through. Two rotating shafts 19 are symmetrically mounted on the turntable 17 through the through hole 18. Each rotating shaft 19 is fitted with a cleaning ring 20 for cleaning the fuzz on the surface of the yarn. Each cleaning ring 20 is made of high-elasticity, wear-resistant polyurethane material with a rough surface. Two wedge blocks 21 are symmetrically slidably mounted inside the turntable 17. The sliding direction of each wedge block 21 is towards the center of the turntable 17. Each wedge block 21 is fixedly connected to the inner wall of the turntable 17 by a first spring 22. Several limiting strips 23 are slidably mounted on each rotating shaft 19. One side of each limiting strip 23 is fixedly connected to the inner wall of the corresponding cleaning ring 20, and the other side is set as an inclined surface. A top rod 24 is vertically slidably mounted inside each rotating shaft 19. The upper end of each top rod 24 is connected to the corresponding limiting strip 23. The inclined surfaces of the three components are matched, and the lower ends of each component are matched with the inclined surfaces of the corresponding wedge blocks 21. An internal gear ring 26 is fixedly installed on each frame 1, and a gear 25 that meshes with the internal gear ring 26 is fixedly installed on the upper end of each rotating shaft 19. The rotation direction of the turntable 17 is the same as the yarn twisting rotation direction, and the rotation direction of the rotating shaft 19 and the cleaning ring 20 is opposite to the yarn twisting rotation direction. The third motor 14 drives the turntable 17 to rotate through the synchronous pulley 15 and the synchronous belt 16. During the rotation of the turntable 17, the wedge blocks 21 slide towards the center of the turntable 17. Therefore, when the turntable 17 rotates, the wedge blocks 21 will be subjected to centrifugal force and overcome the elastic force of the first spring 22 to slide. Through the limiting of the inclined surface of the wedge block 21 on the top rod 24, the top rod 24 will slide upward. The engagement of the end with the inclined surface of the limiting strip 23 causes the limiting strip 23 on the rotating shaft 19 to slide centrifugally synchronously, expanding the diameter of the cleaning ring 20. The surface of the cleaning ring 20 will then contact the yarn surface. When the turntable 17 rotates, it will drive the rotating shaft 19 and the cleaning ring 20 to perform circular motion. Through the meshing of the gear 25 and the internal gear ring 26, the rotating shaft 19 and the cleaning ring 20 will rotate simultaneously while performing circular motion. Since the rotation direction of the turntable 17 is the same as the yarn twisting rotation direction, while the rotation direction of the rotating shaft 19 and the cleaning ring 20 is opposite to the yarn twisting rotation direction, loose fibers will fall off due to friction, while firmly attached fibers will be twisted back into the yarn along the yarn rotation direction. This effectively cleans the fibers on the yarn surface without causing new fibers to form.This design makes the yarn surface smoother, facilitating the penetration of subsequent anti-mite liquid. When there is more yarn fuzz, the turntable 17 rotates faster, the wedge block 21 slides further, the cleaning ring 20 is stretched to a larger diameter, and the distance between the two cleaning rings 20 decreases, gradually increasing the pressure on the yarn. The faster the cleaning ring 20 rotates, the stronger the cleaning ability against fuzz. Conversely, if there is less yarn fuzz, the turntable 17 rotates slower, reducing the cleaning ability and preventing excessive friction that could cause yarn wear or new fuzz. This design effectively adjusts the cleaning ability according to the actual amount of yarn fuzz, ensuring effective cleaning while minimizing damage to the yarn.

[0020] Two wedge-shaped bars 27 are symmetrically slidably installed inside the turntable 17. Each wedge 21 has a stop bar 28 fixedly installed on one side for limiting the wedge 27. Each wedge 27 is fixedly connected to the inner wall of the turntable 17 by a second spring 29. Each wedge 27 is fixedly installed with a sleeve 30. Each sleeve 30 is fitted with a brush roller 31 for removing lint adhering to the cleaning ring 20. The top inner wall of each brush roller 31 is fixedly connected to the top of the corresponding sleeve 30 by a torsion spring 39. Each brush roller 31 slides vertically inside. Each sleeve 30 is equipped with a screw 32, which is located inside the corresponding sleeve 30. Each sleeve 30 has a spiral groove 33 on its inner wall that mates with the screw 32. A pressure sensing plate 34 for detecting the surface friction of the cleaning ring 20 is fixedly installed at the bottom of each sleeve 30. When the wedge block 21 slides, it drives the stop bar 28 to move together. Through the cooperation between the stop bar 28 and the inclined surface of the wedge bar 27, the wedge bar 27 overcomes the elastic force of the second spring 29 and slides. The wedge bar 27 does not slide towards the center of the turntable 17 and is not subject to centrifugal force. As the wedge strip 27 slides, the diameter of the cleaning ring 20 gradually increases, and the brush roller 31 also gradually slides. The distance between the brush roller 31 and the cleaning ring 20 remains consistent. When the cleaning ring 20 rotates, it will rub against the brush roller 31. The brush roller 31 can brush off the lint adhering to the surface of the cleaning ring 20 and keep the surface of the cleaning ring 20 rough, preventing the surface of the cleaning ring 20 from adhering to lint or becoming smooth due to yarn friction, which would affect the cleaning effect. At the same time, the brush roller 31 will be subjected to the friction force of the cleaning ring 20 and overcome the torsion spring 39 on the sleeve 30. The elastic force causes the screw 32 to rotate to a certain extent, and the screw 32 will also rotate to a certain extent driven by the brush roller 31. The screw 32 will slide upward through the spiral groove 33 and no longer touch the pressure sensing plate 34. The cleaning ring 20 will gradually wear during use, and the friction force on the brush roller 31 will gradually decrease. The upward sliding range of the screw 32 will also gradually decrease. When the wear reaches a certain level, the screw 32 will press against the pressure sensing plate 34, prompting the staff to replace the cleaning ring 20 to maintain a good cleaning effect.

[0021] A dust collection mechanism 35 is fixedly installed on one side of the frame 1. An outer ring 36 is fixedly installed at the suction end of the dust collection mechanism 35. An inner ring 37, which is rotated by the turntable 17, is rotatably installed inside the outer ring 36. The inner ring 37 is provided with several dust collection ports 38 for extracting lint. When the turntable 17 rotates, it will drive the inner ring 37 to rotate together. The dust collection ports 38 on the inner ring 37 are always aligned with the friction position between the cleaning ring 20 and the yarn and the contact position between the cleaning ring 20 and the brush roller 31, so that the cleaned lint can be sucked up in time. After the lint enters between the outer ring 36 and the inner ring 37, it will be moved into the dust collection mechanism 35 by the airflow and stored to prevent the lint from adhering to the yarn again or causing pollution to the environment.

[0022] Specifically, first, the yarn roll is placed on the bushing 2, and a winding spindle is installed on the electric shaft 9. One end of the yarn is then wound according to... Figure 2The yarn, as shown by the dotted line, enters through the wire hole 3 at the top of the bushing 2 and exits through the wire hole 3 at the bottom of the bushing 2. It then passes upwards through the wire ring 6, and is first inserted into the slot of the lower wire roller 7, then into the detection slot of the photoelectric hair detector 13. It continues upwards through the through hole 18 of the turntable 17, passing between the two cleaning rings 20. The yarn is then inserted into the slot of the upper wire roller 7, and finally the end of the yarn is wound onto the take-up spindle on the electric shaft 9. After starting the equipment, the first motor 8 drives one of the wire rollers 7 to rotate. The two wire rollers 7 rotate synchronously via the belt drive mechanism on the frame 1. The electric shaft 9 then drives the take-up spindle to take up the yarn, and the second motor 10 drives the rotating drum 11 to... The rotation causes the yarn to reciprocate and slide on the electric shaft 9 for winding. The yarn on the yarn roll is continuously pulled out and moves along the guide hole 3 in the bushing 2. At the same time, the bushing 2 will continue to rotate, while the yarn bobbin 4 drives the yarn roll to remain stationary. The pulled-out yarn will rotate on its own axis while moving in a circular motion along the yarn bobbin 4, thus twisting the yarn. The rotation amplitude of the rotating yarn is limited after passing through the guide ring 6, making it less likely for the yarn to fall off the guide roller 7. The yarn between the two guide rollers 7 will maintain a straight line motion. The photoelectric hairiness detector 13 detects the amount of hairiness of the yarn in real time and controls the output power of the third motor 14. The third motor 14 drives the turntable 17 to rotate through the synchronous pulley 15 and the synchronous belt 16. The wedge block 21 slides under centrifugal force, causing the top rod 2 to move. 4. Sliding upwards, the limiting strip 23 on the rotating shaft 19 is limited by the top rod 24 and slides centrifugally, expanding the diameter of the cleaning ring 20. The surface of the cleaning ring 20 will contact the yarn surface. When the turntable 17 rotates, the rotating shaft 19 and the cleaning ring 20 rotate simultaneously in a circular motion. Loose fuzz will fall off due to friction, while firmly attached fuzz will be twisted back into the yarn along the direction of yarn rotation. This effectively cleans the fuzz on the yarn surface. The more fuzz there is in the yarn, the faster the rotation speed of the turntable 17, the longer the sliding distance of the wedge block 21, the larger the diameter of the cleaning ring 20, and the smaller the gap between the two cleaning rings 20. The pressure on the yarn also gradually increases. The faster the rotation speed of the cleaning ring 20, the stronger its cleaning ability. Conversely, if the yarn... When there is less fuzz, the rotation speed of turntable 17 decreases, and the cleaning ability for fuzz also decreases. This allows for effective adjustment of the cleaning ability based on the actual amount of fuzz in the yarn. When wedge block 21 slides, it drives stop bar 28 to move together, causing wedge bar 27 to drive brush roller 31 to slide. The distance between brush roller 31 and cleaning ring 20 remains consistent. As cleaning ring 20 rotates, it rubs against brush roller 31. Brush roller 31 brushes off the fuzz adhering to the surface of cleaning ring 20, keeping the surface of cleaning ring 20 rough to prevent fuzz from adhering to the surface or becoming smooth due to yarn friction, thus affecting the cleaning effect. Simultaneously, brush roller 31 is subjected to the frictional force of cleaning ring 20, causing screw 32 to rotate to a certain extent within sleeve 30. Screw 32 then slides upwards.The pressure sensor plate 34 is no longer touched. When wear reaches a certain level, the screw 32 will press against the pressure sensor plate 34, prompting the operator to replace the cleaning ring 20 to maintain good cleaning performance. When the turntable 17 rotates, it will drive the inner ring 37 to rotate as well. The suction port 38 on the inner ring 37 is always aligned with the friction point between the cleaning ring 20 and the yarn, and the contact point between the cleaning ring 20 and the brush roller 31, enabling immediate removal of the cleaned lint. After the lint enters between the outer ring 36 and the inner ring 37, it will be moved by airflow into the suction mechanism 35 for storage, preventing the lint from adhering to the yarn again or causing environmental pollution.

Select suitable cashmere raw materials for washing, sorting, and combing to remove coarse hair, dander, and impurities; S2. Dyeing and finishing the cashmere raw materials, and adding finishing oil to increase fiber cohesion and eliminate static electricity; S3. Use a carding machine to card the fiber raw material after carding, and then further stretch and twist the carded fiber sliver on a roving frame to make roving packages. S4.
