Description

Technical Field

[0001] The invention relates to the technical field of cotton carding, in particular to a spinning process and a cotton carding device combining semi-worsted spinning and sirotonic spinning technologies. Background Art

[0002] The spinning process combining semi-worsted spinning and siro spinning is an innovative spinning technology, which combines the advantages of semi-worsted spinning and siro spinning, and aims to produce high-quality and diversified yarns. Semi-worsted spinning is a spinning process between worsted spinning and woolen spinning. It uses special equipment configuration and raw materials to spin yarns between worsted spinning and woolen spinning. This process has the advantages of short production process, high output, labor saving, low cost, etc., and the yarn produced has excellent properties such as bright color, uniform fiber blending, fluffy and soft feel, smooth surface, etc. Siro spinning is a spinning method of spinning, doubling and twisting. It uses two coarse yarns to feed a leather ring drafting device at the same time, and forms a ply after drafting and twisting. The yarn structure of siro spinning is loose inside and straight outside, with good feel, suitable for light and thin fabrics, and has a short process, low energy consumption and high economic benefits. In the actual spinning process, the prepared raw materials first need to be pre-treated for semi-worsted spinning, and then roving is prepared and then siro spinning is carried out. In the semi-worsted pre-treatment, the raw materials need to be pre-treated such as wool mixing, combing, and drawing to prepare fiber strips suitable for semi-worsted spinning. In the combing process, the compactness of different batches of raw fibers is different, and the holding force of the needle cloth on the cylinder is different. When the raw fibers are relatively loose, the needle cloth on the movable cover plate is easy to hook up the raw fibers and form cover plate flowers on the movable cover plate. The cover plate flowers are easy to affect the subsequent combing and impurity removal work of the movable cover plate. When the raw fibers are relatively compact, the holding force of the cylinder is greater, and the movable cover plate may be difficult to achieve good combing and impurity removal effects. For this reason, we propose a spinning process and a combing device that combines semi-worsted spinning with siro spinning technology. Summary of the invention

[0012] Preferably, a clamping strip is fixedly mounted on each of the movable cover plates, and a plurality of limiting grooves cooperating with the clamping strip are arranged on each of the rotating shafts.

[0013] A spinning process of a carding device combining semi-worsted spinning and sirotonic spinning technology, specifically comprising the following steps: S1. According to product requirements, select appropriate spinning raw materials, clean and loosen the raw materials, remove impurities and lumps, and keep the fibers in the best condition; S2. Put the prepared raw materials into the cotton storage bin. The cotton feeding roller feeds the raw materials in the cotton storage bin into the cotton combing bin. The three licker-in rollers loosen and remove impurities from the raw materials. The raw materials are conveyed to the cylinder by the cotton feeding roller and the three licker-in rollers. After the needle clothing on the fixed cover plate contacts the raw materials, the fixed cover plate is subjected to resistance. The fixed cover plate will drive the arc strip to move along the arc groove, causing the lower end of the telescopic rod to rotate. At the same time, the telescopic rod will shorten, and its upper end will drive the baffle to move toward the inner wall of the device plate, compressing the spring. After the baffle plate releases the limit on the baffle strip, the elastic force of the torsion spring will drive the sleeve to rotate, and reel the winding rope to pull the baffle strip to move in the device plate. The sleeve reels one end of the connecting rope and pulls the rotating drum downward, which drives the rotating shaft to move downward, shortening the distance between the movable cover and the cylinder. The motor drives the second transmission wheel and the corresponding rotating shaft to rotate through the transmission belt, and drives the movable cover to move in the opposite direction of the rotation of the cylinder through the transmission of the chain. The movable cover can effectively comb the raw fibers, and then the doffer transfers the combed raw fibers on the cylinder layer by layer. Through the transmission of the belt transmission device, the stripping roller strips the raw fibers on the doffer and transfers them to the cotton collecting device. The cotton collecting device combines the combed raw fibers into cotton strips and discharges them from the strip outlet hole. S3, spinning the combed raw fiber to form yarn, and adjusting the thickness, strength, etc. of the yarn as needed; S4, feeding two rovings that have undergone semi-worsted pre-treatment into a Siro spinning frame at the same time, and performing drafting and twisting to form yarns with Siro spinning characteristics; S5, twisting, strengthening and shaping the yarn; S6. Wind the yarn into a reel for subsequent weaving or textile processing.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention utilizes the resistance of the raw material fiber to the fixed cover plate to push the fixed cover plate to overcome the resistance of the spring and move. When the raw material fiber is relatively loose, the resistance to the fixed cover plate is small, the fixed cover plate has a small movement range, the baffle plate and the baffle bar have a small movement range, the sleeve rotation has a small winding of the connecting rope, the height of the rotating shaft is high, and the distance between the movable cover plate and the cylinder is large, which can reduce the generation of cover plate flowers. When the raw material fiber is relatively tight, the fixed cover plate has a large movement range, the baffle plate and the baffle bar have a large movement range, the sleeve has a large winding of the connecting rope, the rotating shaft has a large descending range, and the distance between the movable cover plate and the cylinder is small, which can achieve good loosening and impurity removal effects; 2. The present invention uses a baffle to limit the baffle bar. When cotton knots appear in the raw material fibers, the cotton knots will increase the resistance to the fixed cover plate. When the resistance to a single or multiple fixed cover plates increases, since the elastic force of the torsion spring is less than the elastic force of the two springs, the baffle bar cannot move as long as one of the fixed cover plates does not move, thereby reducing the influence of the cotton knots on the resistance to the fixed cover plates.

[0015] 3. The present invention utilizes the second transmission wheel to drive the turntable to rotate. When the arc block on the turntable contacts the arc surface at the end of the limit rod, it will push the limit rod to move into the cotton combing bin, and the limit rod will push the brush strip to move so that the elastic strip is compressed. After the arc block releases the limit on the end of the limit rod, the elastic force of the elastic strip pushes the brush strip and the limit rod to reset, and then the next arc block pushes the limit rod again, so that the limit rod drives the brush strip to reciprocate, and the brush strip can clean the surface of the movable cover plate. At the same time, the cover plate flowers loosened by the brush strip on the movable cover plate will be promptly sucked away by the corresponding cotton suction cylinder, reducing the influence of the cover plate flowers on the subsequent cotton combing of the movable cover plate.

The feeding roller 5 feeds the raw materials in the cotton storage bin 2 into the subsequent combing process, and the three licker-in rollers 6 open and remove impurities from the raw materials. The raw materials are conveyed to the cylinder 7 by the feeding roller 5 and the three licker-in rollers 6. The motor 12 will drive the doffer 8 to rotate through the meshing of the first gear 13 and the fourth gear 16. The doffer 8 8 transfers the combed raw fibers on the cylinder 7 layer by layer, and through the transmission of the belt transmission device 17, the cotton stripping roller 9 strips the raw fibers on the doffer 8 and passes them into the cotton collecting device 10, and the cotton collecting device 10 combines the combed raw fibers into cotton strips and discharges them from the strip outlet hole 11. A cotton drop suction device 3 is fixedly installed on the cotton combing bin 1, and a plurality of cotton suction cylinders 4 are fixedly installed in the cotton combing bin 1. The cotton drop suction device 3 can suck away the scattered impurities and short fibers in the cotton combing bin 1 through the cotton suction cylinders 4, thereby reducing the influence of impurities and short fibers on the cotton combing process.

[0020] A device plate 18 is fixedly installed in the combing bin 1, and a plurality of limit plates 19 are fixedly installed at the lower end of the device plate 18. A fixed cover plate 21 is slidably installed between two adjacent limit plates 19. Arc strips 22 are fixedly installed on both sides of each fixed cover plate 21. Each limit plate 19 is provided with an arc groove 20 for limiting the arc strip 22. A telescopic rod 23 is rotatably installed on each fixed cover plate 21, and a baffle 24 is fixedly installed on the upper end of each telescopic rod 23. Each baffle 24 is slidably installed in the device plate 18, and two springs 25 are fixedly connected to the inner wall of the device plate 18. A baffle bar 26 limited by the baffle 24 is slidably installed in the device plate 18. A limit plate 28 is fixedly installed on the inner wall of the combing bin 1, and a slidable stop plate 28 is provided on the limit plate 28. Four rotating shafts 31 driven by a motor 12 are provided, two chains 48 are installed for transmission between the four rotating shafts 31, a plurality of movable cover plates 35 are fixedly installed between the two chains 48, a clamping strip 36 is fixedly installed on each movable cover plate 35, a plurality of limiting grooves 37 matching with the clamping strip 36 are provided on each rotating shaft 31, a rotating drum 33 is rotatably installed at one end of each rotating shaft 31, an elastic column 32 is fixedly installed between each rotating drum 33 and a limiting plate 28, a sleeve 29 is rotatably installed in the limiting plate 28, a torsion spring 30 is fixedly installed between the sleeve 29 and the inner wall of the limiting plate 28, a winding rope 27 is fixedly installed at one end of the blocking bar 26, one end of the winding rope 27 is wound around the sleeve 29, and the end is fixedly connected to the sleeve 29, each rotating drum 33 is connected to the sleeve 29 There is a connecting rope 34 fixedly connected between them. The torsion spring 30 is always in a rotating force storage state, and its elastic force is less than the elastic force of the two springs 25, but greater than the elastic force of the four elastic columns 32. During the rotation of the cylinder 7, the needle cloth on it will drive the raw fiber to move together. After the needle cloth on the fixed cover plate 21 contacts the raw fiber, the fixed cover plate 21 will be subjected to resistance. The fixed cover plate 21 will drive the arc strip 22 to move along the arc groove 20, causing the lower end of the telescopic rod 23 to rotate. At the same time, the telescopic rod 23 will be shortened, and its upper end will drive the baffle 24 to move toward the inner wall of the device plate 18, causing the spring 25 to be compressed. According to the looseness of the raw material limit, the fixed cover plate 21 will be subjected to different resistances, and the baffle 24 will retract to different degrees. After the baffle 24 releases the limit on the baffle bar 26, The elastic force of the torsion spring 30 will drive the sleeve 29 to rotate, and reel in the winding rope 27, pulling the baffle 26 to move in the device plate 18. Since the elastic force of the torsion spring 30 is less than the elastic force of the two springs 25, when the baffle 24 stops moving, the baffle 26 will also stop moving, and the sleeve 29 cannot rotate either. When the sleeve 29 rotates, it will reel in one end of the connecting rope 34 and pull the rotating drum 33 downward to stretch the elastic column 32. At the same time, the rotating drum 33 will drive the rotating shaft 31 to move downward, shortening the distance between the movable cover plate 35 and the cylinder 7. When the raw material fiber is relatively loose, the resistance to the fixed cover plate 21 is relatively small, the movement amplitude of the fixed cover plate 21 is relatively small, the movement amplitude of the baffle 24 and the baffle 26 is also relatively small, and the sleeve 29 rotation has less effect on the winding of the connecting rope 34.The height of the rotating shaft 31 is relatively high, and the distance between the movable cover plate 35 and the cylinder 7 is relatively large, which can reduce the generation of cover plate flowers. When the raw material fiber is relatively compact, the fixed cover plate 21 has a relatively large movement range, and the movement range of the baffle plate 24 and the baffle bar 26 is also relatively large. The sleeve 29 also reels more of the connecting rope 34, and the rotating shaft 31 drops relatively large. The distance between the movable cover plate 35 and the cylinder 7 is relatively small, which can achieve good opening and impurity removal effects. When cotton knots appear in the raw material fiber, the cotton knots will increase the resistance of the fixed cover plate 21. When the resistance of a single or multiple fixed cover plates 21 increases, since the elastic force of the torsion spring 30 is less than the elastic force of the two springs 25, as long as there is a fixed cover plate 21 that does not move, the baffle bar 26 cannot move, which reduces the influence of cotton knots on the resistance of the fixed cover plate 21.

[0021] A second transmission wheel 39 is fixedly installed at the end of one of the rotating shafts 31, a first transmission wheel 38 is fixedly installed at the output end of the motor 12, a transmission belt 40 is installed between the first transmission wheel 38 and the second transmission wheel 39, a plurality of brush strips 44 for cleaning the movable cover plate 35 are slidably installed in the cotton combing bin 1, each brush strip 44 is fixedly connected to the inner wall of the cotton combing bin 1 by an elastic strip 45, a cotton suction cylinder 4 is arranged between two adjacent brush strips 44, and a limit rod 46 is slidably installed on the cotton combing bin 1. One end of each brush strip 44 is fixedly connected to one end of a limiting rod 46, and the other end of the limiting rod 46 is set in an arc shape. A turntable 43 is fixedly installed on the second transmission wheel 39, and a plurality of arc blocks 47 for limiting the limiting rod 46 are fixedly installed on one side of the turntable 43. The diameter of the arc block 47 is larger than the diameter of the end of the limiting rod 46. An elastic rod 42 is fixedly installed on the outer wall of the cotton combing bin 1. The elastic rod 42 is always in a compressed state, and a tensioning wheel 41 cooperating with the transmission belt 40 is rotatably installed on its end. When the motor 12 is working, the transmission belt 40 drives the second transmission wheel 39 and the corresponding rotating shaft 31 to rotate, and the chain 48 drives the movable cover plate 35 to move in the opposite direction to the rotation of the cylinder 7. At the same time, the second transmission wheel 39 drives the rotating disk 43 to rotate. When the arc block 47 on the rotating disk 43 contacts the arc surface at the end of the limiting rod 46, the limiting rod 46 will be pushed to move into the cotton combing bin 1. The limiting rod 46 will push the brush strip 44 to move so that the elastic strip 4 5 is compressed, and after the arc block 47 releases the limit on the end of the limit rod 46, the elastic force of the elastic strip 45 pushes the brush strip 44 and the limit rod 46 to reset, and then the next arc block 47 pushes the limit rod 46 again, so that the limit rod 46 drives the brush strip 44 to reciprocate, and the brush strip 44 can clean the surface of the movable cover plate 35. At the same time, the cover plate flowers on the movable cover plate 35 that are loosened by the brush strip 44 will be sucked away by the corresponding cotton suction cylinder 4 in time, reducing the influence of the cover plate flowers on the subsequent combing of the movable cover plate 35.

[0022] Specifically, the motor 12 is first started to drive the first gear 13 to rotate, and the first gear 13 is meshed with the second gear 14, and the second gear 14 is meshed with the third gear 15, which drives the feeding roller 5 and the three licker-in rollers 6 to rotate. The feeding roller 5 feeds the raw material in the cotton storage bin 2 to the subsequent combing process, and the three licker-in rollers 6 open and remove impurities on the raw material fibers. The raw material fibers are conveyed to the cylinder 7 by the feeding roller 5 and the three licker-in rollers 6. The motor 12 drives the doffer 8 to rotate through the meshing of the first gear 13 and the fourth gear 16. The doffer 8 transfers the combed raw material fibers on the cylinder 7 layer by layer. The stripping roller 9 strips the raw material fibers on the doffer 8 through the transmission of the belt transmission device 17, and transmits them to the cotton collecting device 10. In the process, the cotton collecting device 10 combines the combed raw fibers into cotton strips and discharges them from the strip outlet hole 11. During the rotation of the cylinder 7, the needle cloth on it will drive the raw fibers to move together. After the needle cloth on the fixed cover plate 21 contacts the raw fibers, the fixed cover plate 21 will be subjected to resistance. The fixed cover plate 21 will drive the arc strip 22 to move along the arc groove 20, causing the lower end of the telescopic rod 23 to rotate. At the same time, the telescopic rod 23 will shorten, and its upper end will drive the baffle 24 to move toward the inner wall of the device plate 18, so that the spring 25 is compressed. According to the looseness of the raw material limit, the fixed cover plate 21 will be subjected to different resistances, and the baffle 24 will retract to different degrees. After the baffle 24 releases the limit on the baffle bar 26, the elastic force of the torsion spring 30 will drive the sleeve 29 to rotate and reel the rope 27 The strip 26 is pulled to move in the device plate 18. Since the elastic force of the torsion spring 30 is less than the elastic force of the two springs 25, when the baffle plate 24 stops moving, the strip 26 will also stop moving, and the sleeve 29 cannot rotate. When the sleeve 29 rotates, one end of the connecting rope 34 will be wound up, and the rotating drum 33 will be pulled downward to stretch the elastic column 32. At the same time, the rotating drum 33 will drive the rotating shaft 31 to move downward, shortening the distance between the movable cover plate 35 and the cylinder 7. When the raw material fiber is relatively loose, the resistance to the fixed cover plate 21 is small, the movement amplitude of the fixed cover plate 21 is small, the movement amplitude of the baffle plate 24 and the strip 26 is also small, the sleeve 29 rotation has less winding on the connecting rope 34, the height of the rotating shaft 31 is high, and the distance between the movable cover plate 35 and the cylinder 7 is large. The larger the distance, the less likely it is that flat plate flowers will be produced. When the raw material fibers are tighter, the fixed flat plate 21 moves more, the baffle 24 and the baffle bar 26 also move more, the sleeve 29 reels more of the connecting rope 34, the shaft 31 drops more, and the movable flat plate 35 is spaced closer to the cylinder 7, which can achieve good loosening and impurity removal effects. When cotton neps appear in the raw material fibers, the cotton neps will increase the resistance of the fixed flat plate 21. When the resistance of a single or multiple fixed flat plates 21 increases, since the elastic force of the torsion spring 30 is less than the elastic force of the two springs 25, as long as there is a fixed flat plate 21 that does not move, the baffle bar 26 cannot move, which reduces the influence of cotton neps on the resistance of the fixed flat plate 21. When the motor 12 is working, it is driven by the transmission belt 40.The second transmission wheel 39 and the corresponding rotating shaft 31 will be driven to rotate, and through the transmission of the chain 48, the movable cover plate 35 will be driven to move in the opposite direction to the rotation of the cylinder 7. At the same time, the second transmission wheel 39 will drive the turntable 43 to rotate. When the arc block 47 on the turntable 43 contacts the arc surface at the end of the limit rod 46, the limit rod 46 will be pushed to move into the combing bin 1, and the limit rod 46 will push the brush strip 44 to move so that the elastic strip 45 is compressed. After the arc block 47 releases the limit on the end of the limit rod 46, the elastic force of the elastic strip 45 pushes the brush strip 44 and the limit rod 46 to reset, and then the next arc block 47 pushes the limit rod 46 again, so that the limit rod 46 drives the brush strip 44 to reciprocate, and the brush strip 44 can clean the surface of the movable cover plate 35. At the same time, the cover plate flowers on the movable cover plate 35 that are brushed loose by the brush strip 44 will be promptly sucked away by the corresponding cotton suction cylinder 4, reducing the influence of the cover plate flowers on the subsequent combing of the movable cover plate 35. ,

According to product requirements, select appropriate spinning raw materials, clean and loosen the raw materials, remove impurities and lumps, and keep the fibers in the best condition; S2. Put the prepared raw materials into the cotton storage bin 2. The cotton feeding roller 5 feeds the raw materials in the cotton storage bin 2 into the cotton combing bin 1. The three licker-in rollers 6 loosen and remove impurities from the raw materials. The raw materials are conveyed to the cylinder 7 by the cotton feeding roller 5 and the three licker-in rollers 6. After the needle cloth on the fixed cover plate 21 contacts the raw materials, the fixed cover plate 21 is subjected to resistance.
