Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of carding, in particular to a spinning process combining semi-worsted spinning with sirospun technology and a carding device. BACKGROUND

[0002] The spinning process combining semi-worsted spinning with sirospun technology is an innovative spinning technology, which combines the advantages of semi-worsted spinning and sirospun technology, aiming to produce high-quality and diversified yarns. Semi-worsted spinning is a spinning process between worsted spinning and roving spinning, which uses special equipment configuration and raw materials to spin yarns between worsted spinning and roving spinning. This process has the advantages of short production process, high yield, labor saving, and low cost, and the produced yarns have excellent properties such as bright color, uniform fiber mixing, soft and fluffy hand feeling, and smooth surface. Sirospun is a three-in-one spinning method of spinning, doubling, and twisting, which uses two rovings to feed into a apron drafting device, and forms a strand after drafting and twisting. The yarn structure of sirospun is loose inside and stiff outside, with good hand feeling, suitable for light and thin fabrics, and short process, low energy consumption, and high economic benefit.

[0003] In actual spinning process, the prepared raw materials need to be pre-processed by semi-worsted spinning first, then prepared into rovings, and then spun by sirospun. In the pre-processing of semi-worsted spinning, the raw materials need to be processed by carding, combing, and drawing to prepare fiber slivers suitable for semi-worsted spinning. In the carding process, the compactness of different batches of raw material fibers is different, and the gripping force of the needle cloth on the cylinder is different. When the raw material fibers are relatively loose, the needle cloth on the movable flat plate is easy to hook the raw material fibers and form flat plate flowers on the movable flat plate, which can affect the subsequent carding and impurity removal of the movable flat plate. When the raw material fibers are relatively compact, the gripping force of the cylinder is larger, and the movable flat plate may not play a good carding and impurity removal effect. Therefore, we propose a spinning process combining semi-worsted spinning with sirospun technology and a carding device. SUMMARY

[0016] S1. According to product requirements, selecting appropriate spinning raw materials, cleaning and opening the raw materials, removing impurities and lumps, and making the fibers in the best state;

[0017] S2. Placing the prepared raw materials into the cotton storage bin, feeding the raw materials in the cotton storage bin into the cotton storage bin by the feed roller, opening and removing impurities from the raw material fibers by the three licker-in rollers, and conveying the raw material fibers to the cylinder through the feed roller and the three licker-in rollers; after the raw material fibers contact the card clothing on the fixed cover plate, the fixed cover plate is subjected to resistance, the fixed cover plate drives the arc-shaped strip to move along the arc-shaped groove, the lower end of the telescopic rod rotates, the telescopic rod shortens, the upper end of the telescopic rod drives the baffle to move towards the inner wall of the device plate, the spring is compressed, the baffle removes the limitation of the blocking strip, the elastic force of the torsion spring drives the sleeve to rotate and wind the rope, the blocking strip moves in the device plate, the sleeve winds one end of the connecting rope and pulls down the rotating drum, the rotating drum drives the rotating shaft to move downward, shortens the distance between the movable cover plate and the cylinder, the motor drives the second transmission wheel and the corresponding rotating shaft to rotate through the transmission belt, and the movable cover plate moves in the opposite direction of the cylinder through the transmission of the chain, the movable cover plate can effectively card the raw material fibers, and then the doffer transfers the raw material fibers on the cylinder layer by layer, the stripping roller strips the raw material fibers on the doffer through the transmission of the belt transmission device, and the raw material fibers are transmitted into the cotton collecting device, the cotton collecting device synthesizes the raw material fibers into sliver and discharges the sliver from the sliver hole;

[0018] S3. Coarse spinning the carded raw material fibers to form yarns, and adjusting the thickness and strength of the yarns according to requirements;

[0019] S4. Feeding two coarse yarns prepared by the semi-worsted spinning pretreatment into the sirospun spinning machine at the same time, drafting and twisting the two coarse yarns to form yarns with sirospun characteristics;

[0020] S5, twisting, reinforcing and setting the yarn, etc.

[0021] S6, the yarn is wound into a roll, facilitating subsequent weaving or textile processing.

[0022] Compared with the prior art, the beneficial effects of the present application are:

[0023] 1. The raw material fiber pushes the fixed cover plate to overcome the resistance of the spring. When the raw material fiber is loose, the resistance to the fixed cover plate is small, the movement amplitude of the fixed cover plate is small, the movement amplitude of the baffle and the baffle is also small, the winding of the sleeve on the continuous rope is also small, the height of the rotating shaft is high, 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 tight, the movement amplitude of the fixed cover plate is large, the movement amplitude of the baffle and the baffle is also large, the winding of the sleeve on the continuous rope is also large, the descending amplitude of the rotating shaft is large, the distance between the movable cover plate and the cylinder is small, which can achieve good opening and impurity removal effect.

[0024] 2. The baffle limits the movement of the baffle when the raw material fiber has neps. When the single or multiple fixed cover plates are subjected to increased resistance, the elastic force of the torsional spring is smaller than that of the two springs. As long as the fixed cover plate is not moved, the baffle cannot move, thereby reducing the influence of the neps on the resistance of the fixed cover plate.

[0025] 3. The second transmission wheel drives the rotating disc to rotate. When the arc-shaped block on the rotating disc contacts with the arc-shaped surface at the end of the limiting rod, the limiting rod is pushed to move into the cotton combing bin, the limiting rod pushes the brush bar to be compressed, and the elastic force of the elastic bar pushes the brush bar and the limiting rod to reset. The next arc-shaped block pushes the limiting rod again, so that the limiting rod drives the brush bar to reciprocate. The brush bar can clean the surface of the movable cover plate, and the cover plate flowers loosened by the brush bar on the movable cover plate are timely sucked by the corresponding cotton suction cylinder, thereby reducing the influence of the cover plate flowers on the subsequent cotton combing of the movable cover plate.

When the raw fibers are relatively compact, the movement amplitude of the fixed cover plate 21 is large, and the movement amplitudes of the baffle 24 and the blocking strip 26 are also large. The sleeve 29 winds more on the connecting rope 34, the descending amplitude of the rotating shaft 31 is large, the distance between the movable cover plate 35 and the cylinder 7 is small, which can play a good opening and impurity removal effect. When neps appear in the raw fibers, the neps will increase the resistance received by the fixed cover plate 21. When a single or multiple fixed cover plates 21 receive increased resistance, since the elastic force of the torsional spring 30 is smaller than the elastic force of the two springs 25, as long as there is a fixed cover plate 21 that is not moving, the blocking strip 26 cannot move, thereby reducing the influence of the neps on the resistance received by the fixed cover plate 21.

[0039] One end of each rotating shaft 31 is fixedly installed with a second transmission wheel 39, and the output end of the motor 12 is fixedly installed with a first transmission wheel 38. The first transmission wheel 38 and the second transmission wheel 39 are transmissionally installed with a transmission belt 40. A plurality of brush strips 44 for cleaning the movable cover plate 35 are slidingly installed in the cotton carding bin 1. Each brush strip 44 is fixedly connected with an elastic strip 45 between the inner wall of the cotton carding bin 1. Adjacent two brush strips 44 are provided with a lint roller 4. A limiting rod 46 is slidingly installed on the cotton carding bin 1. One end of each brush strip 44 is fixedly connected to one end of the limiting rod 46. The other end of the limiting rod 46 is arc-shaped. A rotating disc 43 is fixedly installed on the second transmission wheel 39. A plurality of arc-shaped blocks 47 for limiting the limiting rod 46 are fixedly installed on one side of the rotating disc 43. The diameter of the arc-shaped blocks 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 carding bin 1. The elastic rod 42 is always in a compressed state, and the end thereof is rotationally installed with a tension pulley 41 cooperating with the transmission belt 40. When the motor 12 works, the second transmission wheel 39 and the corresponding rotating shaft 31 are driven to rotate through the transmission of the transmission belt 40. The movable cover plate 35 is driven to move in the opposite direction of the cylinder 7 through the transmission of the chain 48. At the same time, the rotating disc 43 is driven to rotate by the second transmission wheel 39. When the arc-shaped blocks 47 on the rotating disc 43 are in contact with the arc-shaped surface of the end of the limiting rod 46, the limiting rod 46 is pushed to move into the cotton carding bin 1. The limiting rod 46 pushes the brush strip 44 to make the elastic strip 45 compressed. After the arc-shaped blocks 47 remove the limiting of the end of the limiting rod 46, the elastic force of the elastic strip 45 pushes the brush strip 44 and the limiting rod 46 to reset. Then, the next arc-shaped block 47 pushes the limiting rod 46 again, so that the limiting rod 46 drives the brush strip 44 to move reciprocally.

gear 15, the feed roller 5 and the three licker-in rollers 6 are driven to rotate, the feed roller 5 sends the raw material in the storage bin 2 into the subsequent carding process, the three licker-in rollers 6 open and remove impurities from the raw material fibers, the raw material fibers are conveyed to the cylinder 7 after being transported by the feed roller 5 and the three licker-in rollers 6, through the meshing of the first gear 13 and the fourth gear 16, the motor 12 drives the doffer 8 to rotate, the doffer 8 transfers the raw material fibers on the cylinder 7 layer by layer,

the card clothing on the fixed flat 21 contacts the raw material fibers, the fixed flat 21 will be subjected to resistance, the fixed flat 21 drives 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 shortens, the upper end of the telescopic rod 23 drives the baffle 24 to move towards the inner wall of the device plate 18, causing the spring 25 to be compressed, according to the loose degree of the raw material limit, the resistance received by the fixed flat 21 is different, the baffle 24 will retract to different degrees, after the baffle 24 removes the limit of the blocking strip 26, the elastic force of the torsional spring 30 drives the sleeve 29 to rotate and winds the rope 27, pulls the blocking strip 26 to move in the device plate 18, because the elastic force of the torsional spring 30 is less than that of the two springs 25, when the baffle 24 stops moving, the blocking strip 26 also stops moving, the sleeve 29 also cannot rotate, when the sleeve 29 rotates, it winds one end of the connecting rope 34 and pulls the rotating drum 33 downward, causing the elastic column 32 to be stretched, at the same time, the rotating drum 33 drives the rotating shaft 31 to move downward, shortening the distance between the movable flat 35 and the cylinder 7, when the raw material fibers are relatively loose, the resistance to the fixed flat 21 is small, the movement amplitude of the fixed flat 21 is small, the movement amplitude of the baffle 24 and the blocking strip 26 is also small, the sleeve 29 rotates less to wind the connecting rope 34, the height of the rotating shaft 31 is higher, the distance between the movable flat 35 and the cylinder 7 is larger, which can reduce the generation of flat waste, when the raw material fibers are relatively compact, the movement amplitude of the fixed flat 21 is larger, the movement amplitude of the baffle 24 and the blocking strip 26 is also larger, the sleeve 29 winds more of the connecting rope 34, the descending amplitude of the rotating shaft 31 is larger, the distance between the movable flat 35 and the cylinder 7 is smaller, which can achieve good opening and impurity removal effect, and when neps appear in the raw material fibers, the neps will increase the resistance received by the fixed flat 21, when a single or multiple fixed flats 21 receive increased resistance, as the elastic force of the torsional spring 30 is less than that of the two springs 25, as long as there is a fixed flat 21 that has not moved, the blocking strip 26 cannot move, which reduces the influence of neps on the resistance received by the fixed flat 21, when the motor 12 works, through the transmission of the transmission belt 40,The second transmission wheel 39 and the corresponding rotating shaft 31 are driven to rotate, the movable cover plate 35 is driven to move in the opposite direction of the cylinder 7 through the transmission of the chain 48, the second transmission wheel 39 drives the rotating disc 43 to rotate, when the arc-shaped block 47 on the rotating disc 43 is in contact with the arc-shaped surface at the end of the limiting rod 46, the limiting rod 46 is pushed to move into the cotton carding bin 1, the limiting rod 46 pushes the brush bar 44 to move to compress the elastic bar 45, after the arc-shaped block 47 releases the limiting of the end of the limiting rod 46, the elastic force of the elastic bar 45 pushes the brush bar 44 and the limiting rod 46 to reset, and then the next arc-shaped block 47 pushes the limiting rod 46 again, so that the limiting rod 46 drives the brush bar 44 to reciprocate, the brush bar 44 can clean the surface of the movable cover plate 35, and the cover plate lint loosened by the brush bar 44 on the movable cover plate 35 is timely sucked away by the corresponding suction cylinder 4, so that the influence of the cover plate lint on the subsequent carding of the movable cover plate 35 is reduced.

A spinning process for a carding device combining semi-worsted and selov spinning technologies, characterized in that: The spinning process using a carding device combining semi-worsted and selov spinning technologies as described in claim 9 specifically includes the following steps: S1. Select appropriate spinning raw materials according to product requirements, clean and open the raw materials to remove impurities and clumps, and put the fibers in the best condition. S2. Place 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 carding bin (1). The three licker-in rollers (6) open and remove impurities from the raw material fibers. The raw material fibers 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) comes into contact with the raw material fibers, the fixed cover plate (21) is subjected to resistance.
