Description

Technical Field

[0001] This invention relates to the field of cashmere blending technology, specifically to a blending device and method for mohair-cashmere blended fibers. Background Technology

[0002] A blending device is used to mix two or more polymer materials with different properties and then produce fibers through a specific process. The key is to achieve uniform mixing and stable spinning of the materials to ensure that the final fiber performance meets the requirements. This technology combines the advantages of different fibers and aims to create textiles with unique properties and appearance. Both or more materials need to be pre-treated to remove impurities, and then they are dyed and dried separately. They are then pre-opened and sealed with oil and water. Finally, the two or more materials are uniformly mixed by a blending machine to ensure the uniform distribution of different fibers. The mixed materials are then spun into yarn by a combing device and a spinning device. After the yarn goes through winding, doubling, and twisting processes, the yarn performance can be improved. In the actual blending process of mohair and cashmere, they are usually transported together to a blending machine using airflow, and then mixed by the blending machine. Due to the certain density difference between mohair and cashmere, mohair settles faster than cashmere during the falling process, which easily leads to the separation of the two raw materials. In addition, because cashmere has a higher loft, it tends to occupy the upper layer of the airflow, resulting in a floating wool zone. When the feeding curtain of the blending machine grabs the fiber raw materials, it usually grabs them from the bottom, resulting in the first raw materials grabbed having a higher mohair content. This leads to the situation where the mohair is not fully opened during the opening process. The raw materials grabbed later have a higher cashmere content, which may cause the cashmere to break during the opening process. Both situations may affect the subsequent yarn production. To address this, we propose a blending device and blending method for mohair and cashmere blended fibers. Summary of the Invention

[0005] Preferably, the feeding chamber is provided with two pusher plates, and a guide block is fixedly installed at one end of each pusher plate. Two loop grooves are provided on one inner wall of the feeding chamber for limiting the guide block. A drive device for driving the two pusher plates to move symmetrically along the corresponding loop grooves is fixedly installed on the other side of the feeding chamber.

[0006] Preferably, each of the guide blocks is configured as a pentagon, wherein one of the vertices of the quadrilateral is configured as a wedge, a first magnetic block is fixedly installed on the inclined surface of each guide block, and a first magnetic plate that cooperates with the first magnetic block is fixedly installed on the inner wall of one side of each of the spiral grooves.

[0008] Preferably, the first magnetic plate and the second magnetic block are magnetically repulsive, and the magnetic attraction between the third magnetic block and the third magnetic plate is greater than the magnetic attraction between the second magnetic block and the second magnetic plate.

[0009] Preferably, a gear is fixedly installed at one end of each of the first rotating shafts, and a rack that meshes with the corresponding gear is fixedly installed on the inner walls of both sides of each V-groove.

The angled nails on the feeding curtain are all inclined in their direction of movement, and the angled nails on the unloading plate are inclined in the opposite direction to the angled nails on the feeding curtain. An angled nail is also fixedly installed at the lower end of each pusher plate.

[0012] Preferably, the first stirring shafts on the two first rotating shafts are arranged in a cross configuration, and the second stirring shafts on the two second rotating shafts are also arranged in a cross configuration.

[0013] A blending method for a blending device for mohair and cashmere blended fibers specifically includes the following steps: S1. Select suitable mohair and cashmere raw materials and pre-treat them respectively; S2. The mohair and cashmere raw materials are dyed separately, dried and pre-opened, and then oil and water are added separately for simmering. S3. Mohair and cashmere raw materials are conveyed into the feed cylinder via airflow. The cylinder is activated and reciprocates continuously, driving one of the two first rotating shafts to move upward and the other downward. During the movement of the first rotating shaft, the first stirring shaft on it rotates, thoroughly mixing the fiber raw materials at the lower and upper ends of the feed cylinder. Simultaneously, the motor drives the two second rotating shafts and their second stirring shafts to rotate in opposite directions, mixing the mohair and cashmere in the wool feeding bin, reducing stratification during the falling of the two raw materials. The drive device drives the two pusher plates to move continuously along the corresponding loop grooves. Two pusher plates move relative to each other along the bottom of the spiral groove. The two pusher plates gather the fiber material at the bottom of the feeding curtain to the middle of the two pusher plates. After the guide block moves to the corner of the bottom of the spiral groove, it drives the pusher plates to rotate. The two pusher plates will combine into a V shape and then rise together synchronously, which will also drive the fiber material at the bottom of the feeding curtain to rise together. The two second rotating shafts drive the second stirring shaft to stir and mix the fiber material between the two pusher plates upward. At the same time, the motor drives the feeding curtain to move. The baffle plate prevents too much fiber material from accumulating on the feeding curtain. The ejector plate will rotate back and forth to remove the excess fiber material on the feeding curtain. S4. The feeding curtain conveys the fiber raw material in the feeding bin to the opening device. After opening, the fiber raw material is fully mixed by the mixing device. S5. The mixed fiber raw materials are fed into a carding machine to make roving, and then the roving is fed into a ring spinning machine for further drafting and twisting into fine yarn. S6. Test all indicators of the blended yarn and select yarns that meet the quality standards.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention utilizes a cylinder to drive a corresponding first rotating shaft to slide obliquely upwards, while another first rotating shaft is pulled downwards by a connecting rope. When the cylinder retracts, the other first rotating shaft is pulled upwards by the elastic force of a spring to reset. The two first rotating shafts are always one upward and the other downward, which allows the fiber raw materials at the lower end of the feed cylinder to be fully mixed with the fiber raw materials at the upper end, reducing the phenomenon of mohair and cashmere separation. At the same time, through the cooperation of gears and racks, the first rotating shaft will continuously drive the first stirring shaft to rotate during the movement, improving the mixing efficiency. 2. This invention utilizes a driving device to drive two pusher plates to move continuously along corresponding loop grooves. When the two pusher plates move relative to each other along the bottom of the loop grooves, they can gather the fiber material at the bottom of the feeding curtain to the middle of the two pusher plates. Then, the guide block will drive the pusher plates to rotate, and the two pusher plates will combine into a V-shape and then rise together synchronously, bringing the fiber material at the bottom of the feeding curtain up with them. The fiber material at the bottom of the feeding curtain with a high mohair content will be transported to the area below the two second rotating shafts. The two second rotating shafts drive the second stirring shaft to stir and mix the fiber material between the two pusher plates upwards, preventing the high mohair content in the fiber material transported by the feeding curtain from failing to achieve a good opening effect and improving the uniformity of feeding the feeding curtain.

[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 1-11This invention provides a technical solution: a blending device for mohair and cashmere blended fibers, comprising a feeding chamber 1, an opening device 2, and a mixing device 3. Three drive shafts 15 are rotatably mounted inside the feeding chamber 1, and a feeding curtain 14 is driven between the three drive shafts 15. One end of the feeding curtain 14 is inclined. Limiting shafts 16 for limiting the feeding curtain 14 are rotatably mounted on both inner walls of the feeding chamber 1. Two second rotating shafts 17 are rotatably mounted inside the feeding chamber 1. Several second stirring shafts 18 for mixing fibers are fixedly mounted on each second rotating shaft 17. The second stirring shafts 18 on the two second rotating shafts 17 are arranged crosswise. Each part is fixedly equipped with a toothed disc 20, and the two toothed discs 20 mesh with each other. A motor 19 is fixedly installed on the feeding bin 1. The output end of the motor 19 is fixedly connected to one of the toothed discs 20. A transmission wheel 21 is fixedly installed on the end of one of the toothed discs 20 and one of the transmission shafts 15. A transmission belt 22 is connected between the two transmission wheels 21. A baffle plate 23 is fixedly installed inside the feeding bin 1. A discharge plate 24 is rotatably installed on the lower end of the baffle plate 23. A push rod 25 is fixedly installed on one end of the discharge plate 24. A connecting rod 26 is rotatably installed on one of the transmission wheels 21. One end of the connecting rod 26 is rotatably connected to the end of the push rod 25, and the other end is eccentrically positioned on the transmission wheel 21. Several angled nails 27 for gripping fibers are fixedly installed on the curtain 14, and several angled nails 27 are also fixedly installed at the end of the unloading plate 24. The angled nails 27 on the feeding curtain 14 are all inclined in the direction of movement, and the angled nails 27 on the unloading plate 24 are inclined in the opposite direction to the angled nails 27 on the feeding curtain 14. The motor 19 first drives the gear plate 20 at its output end to rotate. Through the transmission of the gear plate 20, the two second rotating shafts 17 drive the second stirring shafts 18 on them to rotate in opposite directions. The second stirring shafts 18 mix the mohair and cashmere in the feeding bin 1, reducing the stratification of the two raw materials during the falling process. And because the second stirring shafts 18 on the two second rotating shafts 17 are arranged in a cross pattern, It can improve the mixing effect. At the same time, through the transmission wheel 21 and the transmission belt 22, the transmission shaft 15 is driven to rotate, and the feeding curtain 14 will also start to move, conveying the fiber raw material in the feeding bin 1 to the next process. The baffle plate 23 can prevent excessive fiber raw material from accumulating on the feeding curtain 14. When the transmission wheel 21 rotates, it will drive one end of the connecting rod 26 to perform a circular motion. The other end of the connecting rod 26 will drive one end of the push rod 25 to perform a reciprocating circular motion. The unloading plate 24 will reciprocate to remove excess fiber raw material from the feeding curtain 14. Since the corner nail 27 on the unloading plate 24 is tilted in the opposite direction to the corner nail 27 on the feeding curtain 14, the unloading effect of the unloading plate 24 can be improved.

[0019] A feed cylinder 4 is fixedly installed on the feed hopper 1. Two first rotating shafts 5 are slidably installed inside the feed cylinder 4. Several first stirring shafts 6 for mixing fibers are fixedly installed on each first rotating shaft 5. The first stirring shafts 6 on the two first rotating shafts 5 are arranged in a cross pattern. A slider 8 is rotatably installed at both ends of each first rotating shaft 5. V-shaped grooves 7 for limiting the slider 8 are provided on both sides of the inner wall of the feed cylinder 4. A spring 9 is fixedly connected between each slider 8 and the end of the corresponding V-shaped groove 7. A connecting rope 10 is fixedly connected between every two corresponding sliders 8. A gear 12 is fixedly installed at one end of each first rotating shaft 5. A rack 13 that meshes with the corresponding gear 12 is fixedly installed on both sides of the inner wall of each V-shaped groove 7. A cylinder 11 is fixedly installed on the feed cylinder 4. The output end of the cylinder 11 is fixedly connected to one of the sliders 8. Mohair and cashmere raw materials are transported into the feed cylinder 4 by airflow. The cylinder 11 continuously advances... During the reciprocating extension and retraction of the cylinder 11, the output end slider 8 and the first rotating shaft 5 will slide obliquely along the V-groove 7. Since the two sliders 8 in the V-groove 7 are connected by a connecting rope 10, and a spring 9 is fixedly connected between the slider 8 and the end of the V-groove 7, when the cylinder 11 extends and drives the corresponding first rotating shaft 5 to slide obliquely upward, the other first rotating shaft 5 will be pulled downward by the connecting rope 10, and the corresponding spring 9 will be stretched. When the cylinder 11 retracts, the other first rotating shaft 5 will be pulled upward by the elastic force of the spring 9 to reset. The two first rotating shafts 5 are always one upward and the other downward, so that the fiber raw materials at the lower end of the feed cylinder 4 and the fiber raw materials at the upper end can be fully mixed, reducing the phenomenon of mohair and cashmere separation. At the same time, through the cooperation of the gear 12 and the rack 13, the first rotating shaft 5 will continuously drive the first stirring shaft 6 to rotate during the movement, which improves the mixing efficiency.

[0020] The feeding bin 1 is equipped with two pusher plates 28. Each pusher plate 28 has a corner nail 27 fixedly installed at its lower end, and a guide block 29 fixedly installed at one end of each pusher plate 28. Two loop grooves 30 are provided on one inner wall of the feeding bin 1 to limit the guide blocks 29. A drive device 31 is fixedly installed on the other side of the feeding bin 1 to drive the two pusher plates 28 to move symmetrically along the corresponding loop grooves 30 (the drive device 31 is a known existing structure, so it will not be described in detail in this invention). Each guide block 29 is pentagonal, with one vertex of the pentagon being a wedge. A first magnetic block 32 is fixedly installed on the inclined surface of each guide block 29. A first magnetic plate 35, which cooperates with the first magnetic block 32, is fixedly installed on the inner wall of one side of each loop groove 30. A second magnetic block 33 is disposed in the straight surface above the inclined surface of each guide block 29. The magnetic properties of the first magnetic plate 35 and the second magnetic block 33 are repulsive. A first magnetic plate 35, which cooperates with the first magnetic block 32, is fixedly installed on the inner wall of the top of each loop groove 30. The second magnetic plate 36 cooperates with the two magnetic blocks 33. A third magnetic block 34 is fixedly installed on each guide block 29. Each third magnetic block 34 is symmetrically arranged with the corresponding second magnetic block 33. A third magnetic plate 37 that cooperates with the third magnetic block 34 is fixedly installed on the inner wall of the other side of each loop groove 30. The magnetic attraction between the third magnetic block 34 and the third magnetic plate 37 is greater than the magnetic attraction between the second magnetic block 33 and the second magnetic plate 36. The two push plates 28 are driven by the driving device 31 along the corresponding loop groove 36. 0. During continuous movement, initially, as the two pusher plates 28 move relative to each other along the bottom of the spiral groove 30, they gather the fiber material from the bottom of the feeding curtain 14 to the middle of the two pusher plates 28. After the two pusher plates 28 complete their relative movement, the guide block 29 moves to the bottom corner of the spiral groove 30. Due to the cooperation between the first magnetic block 32 and the first magnetic plate 35, and the magnetic repulsion between the first magnetic plate 35 and the second magnetic block 33, the guide block 29 will drive the pusher plates 28 to rotate. Figure 10 As shown, the two pusher plates 28 will combine into a V-shape and then rise synchronously together, carrying the fiber material at the bottom of the feeding curtain 14 upwards. Due to the vibration of the feeding curtain 14 during the material conveying process, the denser mohair tends to settle at the bottom of the feeding curtain 14. After the pusher plates 28 have finished rising, the fiber material with a high mohair content at the bottom of the feeding curtain 14 will be conveyed to the area below the two second rotating shafts 17. During the rotation of the two second rotating shafts 17 and the second stirring shaft 18, the fiber material between the two pusher plates 28 can be stirred upwards and mixed, preventing the high mohair content in the fiber material conveyed by the feeding curtain 14 from failing to achieve a good opening effect. After the two pusher plates 28 have finished moving upwards, the second magnetic block 33 will be attracted by the magnetic force of the second magnetic plate 36, causing the guide block 29 to drive the pusher plates 28 to rotate again. Then, the drive device 31 will drive the two pusher plates 28 to move in opposite directions, as shown in the attached diagram. Figure 11As shown, the two pusher plates 28 will rotate to a horizontal position for lateral movement, reducing the resistance of movement and preventing the raw material fibers in the middle from moving to both sides, thus preventing excessive accumulation of raw material fibers on both sides. After the two pusher plates 28 have completed their opposite movements, since the magnetic attraction between the third magnetic block 34 and the third magnetic plate 37 is greater than the magnetic attraction between the second magnetic block 33 and the second magnetic plate 36, the guide block 29 will drive the pusher plates 28 to rotate back to the initial vertical position. Then, the drive device 31 will drive the two pusher plates 28 to move downward synchronously to reset, completing one mixing cycle. This can effectively push the raw material fibers with high mohair content at the bottom of the feeding curtain 14 upward and mix them again, improving the uniformity of feeding the feeding curtain 14.

[0021] Specifically, mohair and cashmere raw materials are first conveyed into the feed cylinder 4 via airflow. The cylinder 11 is then activated, continuously reciprocating. During this reciprocating motion, the output slider 8 and the first rotating shaft 5 slide obliquely along the V-groove 7. When the cylinder 11 extends, causing the corresponding first rotating shaft 5 to slide obliquely upwards, the other first rotating shaft 5 is pulled downwards by the connecting rope 10, stretching the corresponding spring 9. When the cylinder 11 retracts, the other first rotating shaft 5 is pulled upwards by the spring force of the spring 9 to reset. The two first rotating shafts 5 are always in a state where one moves upwards and the other downwards, ensuring thorough mixing of the fiber raw materials at the lower and upper ends of the feed cylinder 4. Simultaneously, through the engagement of the gear 12 and rack 13, the first rotating shaft 5... The motor 19 continuously drives the first stirring shaft 6 to rotate, improving mixing efficiency. Simultaneously, the motor 19 first drives the gear disc 20 at its output end to rotate. Through the transmission of the gear disc 20, the two second rotating shafts 17 drive the second stirring shafts 18 on them to rotate in opposite directions. The second stirring shafts 18 mix the mohair and cashmere in the feeding bin 1, reducing stratification during the falling of the two raw materials. Through the transmission wheel 21 and the transmission belt 22, the transmission shaft 15 rotates, and the feeding curtain 14 also begins to move, conveying the fiber raw materials in the feeding bin 1 to the next process. The drive device 31 drives the two pusher plates 28 to move continuously along the corresponding loop groove 30. First, the two pusher plates 28 move relative to each other along the bottom of the loop groove 30. The 28 can gather the fiber material at the bottom of the feeding curtain 14 to the middle of the two pusher plates 28. After the two pusher plates 28 complete their relative movement, the guide block 29 will move to the bottom corner of the loop trough 30. The guide block 29 will drive the pusher plates 28 to rotate, and the two pusher plates 28 will combine into a V shape and then rise together synchronously, carrying the fiber material at the bottom of the feeding curtain 14 to rise together. After the pusher plates 28 have risen, the fiber material at the bottom of the feeding curtain 14 with a high mohair content will be conveyed to the area below the two second rotating shafts 17. The two second rotating shafts 17 drive the second stirring shaft 18 to stir and mix the fiber material between the two pusher plates 28 upwards, preventing the high mohair content in the fiber material conveyed by the feeding curtain 14 from failing to achieve a good opening effect. After the pusher plate 28 completes its upward movement, the second magnetic block 33 is attracted by the magnetic force of the second magnetic plate 36, causing the guide block 29 to drive the pusher plate 28 to rotate again. Then, the drive device 31 drives the two pusher plates 28 to move in opposite directions. The two pusher plates 28 rotate to a horizontal position for lateral movement, reducing the resistance of movement and preventing the raw material fibers in the middle from moving to the sides. After the two pusher plates 28 complete their opposite movements, the guide block 29 drives the pusher plates 28 to rotate back to their initial vertical position. Then, the drive device 31 drives the two pusher plates 28 to move downward synchronously to reset. This effectively pushes the raw material fibers with high mohair content at the bottom of the feeding curtain 14 upward and mixes them again. The baffle plate 23 can prevent excessive fiber raw material from accumulating on the feeding curtain 14.When the transmission wheel 21 rotates, it drives one end of the connecting rod 26 to perform a circular motion. The other end of the connecting rod 26 drives one end of the push rod 25 to perform a reciprocating circular motion. The unloading plate 24 will then rotate reciprocally, removing excess fiber material from the feeding curtain 14.

[0022] A blending method for a blending device for mohair and cashmere blended fibers specifically includes the following steps: S1. Select suitable mohair and cashmere raw materials and pre-treat them respectively; S2. The mohair and cashmere raw materials are dyed separately, dried and pre-opened, and then oil and water are added separately for simmering. S3. Mohair and cashmere raw materials are conveyed into the feed cylinder 4 via airflow. The cylinder 11 is started to reciprocate continuously, driving one of the two first rotating shafts 5 to move upward and the other downward. During the movement of the first rotating shaft 5, the first stirring shaft 6 on it rotates, which fully mixes the fiber raw materials at the lower end and the upper end of the feed cylinder 4. At the same time, the motor 19 drives the two second rotating shafts 17 and the second stirring shaft 18 on them to rotate in opposite directions, mixing the mohair and cashmere in the wool feeding bin 1, reducing the stratification of the two raw materials during the falling process. The drive device 31 drives the two pusher plates 28 to move continuously along the corresponding loop groove 30. First, the two pusher plates 28 move along the loop groove 30. The bottom of the spiral groove 30 moves relative to each other. The two pusher plates 28 gather the fiber material at the bottom of the feeding curtain 14 to the middle of the two pusher plates 28. After the guide block 29 moves to the bottom corner of the spiral groove 30, it drives the pusher plates 28 to rotate. The two pusher plates 28 will combine into a V shape and then rise together synchronously, and will also drive the fiber material at the bottom of the feeding curtain 14 to rise together. The two second rotating shafts 17 drive the second stirring shaft 18 to stir and mix the fiber material between the two pusher plates 28 upward. At the same time, the motor 19 drives the feeding curtain 14 to move. The baffle plate 23 prevents excessive fiber material from accumulating on the feeding curtain 14. The unloading plate 24 will reciprocate to remove excess fiber material from the feeding curtain 14. S4. The feeding curtain 14 conveys the fiber raw material in the feeding bin 1 to the opening device 2. After opening, the fiber raw material is fully mixed by the mixing device 3. S5. The mixed fiber raw materials are fed into a carding machine to make roving, and then the roving is fed into a ring spinning machine for further drafting and twisting into fine yarn. S6. Test all indicators of the blended yarn and select yarns that meet the quality standards.

10. A blending method for a blending apparatus for mohair and cashmere blended fibers, characterized in that: The blending method using the blending apparatus for mohair and cashmere blended fibers as described in claim 9 specifically includes the following steps: S1. Select suitable mohair and cashmere raw materials and pre-treat them respectively; S2. The mohair and cashmere raw materials are dyed separately, dried and pre-opened, and then oil and water are added separately for simmering. S3. Mohair and cashmere raw materials are conveyed to the feed cylinder (4) by airflow. The cylinder (11) is started to reciprocate and extend continuously, driving one of the two first rotating shafts (5) to move upward and the other downward. During the movement, the first rotating shaft (5) drives the first stirring shaft (6) on it to rotate, so as to fully mix the fiber raw materials at the lower end and the upper end of the feed cylinder (4). At the same time, the motor (19) drives the two second rotating shafts (17) and the second stirring shaft (18) on them to rotate in opposite directions, so as to mix the mohair and cashmere in the wool feeding bin (1), reduce the stratification of the two raw materials during the falling process, and drive the two pusher plates (28) to move continuously along the corresponding loop groove (30) through the drive device (31). First, the two pusher plates (28) move along the loop groove (30) 30) The bottom end moves relative to each other. The two pusher plates (28) gather the fiber material at the bottom of the feeding curtain (14) to the middle of the two pusher plates (28). The guide block (29) moves to the bottom corner of the loop groove (30) and drives the pusher plates (28) to rotate. The two pusher plates (28) will combine into a V shape and then rise together synchronously, and will drive the fiber material at the bottom of the feeding curtain (14) to rise together. The two second rotating shafts (17) drive the second stirring shaft (18) to stir and mix the fiber material between the two pusher plates (28) upward. At the same time, the motor (19) drives the feeding curtain (14) to move. The baffle plate (23) prevents too much fiber material from accumulating on the feeding curtain (14). The unloading plate (24) will rotate back and forth to remove the excess fiber material on the feeding curtain (14). S4. The feeding curtain (14) transports the fiber raw material in the feeding bin (1) to the opening device (2). After opening, the fiber raw material is fully mixed by the mixing device (3). S5. The mixed fiber raw materials are fed into a carding machine to make roving, and then the roving is fed into a ring spinning machine for further drafting and twisting into fine yarn. S6. Test all indicators of the blended yarn and select yarns that meet the quality standards.
