Description

Technical Field

[0001] This invention relates to the field of yarn processing technology, specifically to a high-count blended yarn and a device for processing and drawing the yarn. Background Technology

[0002] High-count yarn is a textile term that generally refers to yarn with a higher yarn count. Blended yarn refers to yarn spun from two or more different fibers mixed in a certain proportion, such as polyester-cotton blended yarn and polyester-viscose blended yarn. High-count blended yarn refers to blended yarn with a higher yarn count. Honeycomb polyester, as an existing excellent material, is widely used in the field of blended yarn.

[0003] The existing high-count blended yarns and their processing and drawing equipment have the following shortcomings:

[0004] 1. Honeycomb polyester is prone to static electricity. During the spinning process, it is difficult to control fly waste, which can lead to problems such as yarn sticking, knotting, and fly waste, reducing production efficiency and product quality.

[0005] 2. The feeding mechanism on the existing drawing machine cannot quickly and flexibly adjust the number of slivers to be drawn together, which cannot meet the drawing requirements of slivers with different uniformity.

[0006] 3. The existing roller mechanism on the drawing frame cannot adaptively adjust the roller spacing according to the number of slivers being drawn. When drawing high-count blended yarns, this can easily damage the fibers inside the yarn and reduce the quality of the drawing. Summary of the Invention

[0007] The purpose of this invention is to provide a high-count blended yarn and a device for processing and drawing the yarn.

[0008] To achieve this objective, the present invention adopts the following technical solution:

[0009] A device for processing and drawing high-count blended yarns is provided, including a base and a self-adjusting leveling detection mechanism;

[0010] It also includes a controller, a processing table, a feeding mechanism and a stretching mechanism. The processing table is located on the top of the base, and the self-adjusting and leveling detection mechanism is located on the top of the processing table. The top of the processing table is equipped with a split box.

[0011] The feeding mechanism is located on the top of the processing table. The feeding mechanism includes a lifting rod, an adjusting component, two swing components, several first limit blocks and several second limit blocks. A U-shaped frame is fixedly provided on the top of the processing table. The adjusting component is located on the U-shaped frame. Several second limit blocks are evenly spaced on the adjusting component. Several first limit blocks are evenly spaced at one end of the top of the processing table. Each first limit block and each second limit block has a through hole on its outer wall. Several first stop rods are evenly spaced on the top of the processing table. The lifting rod is slidably mounted on the inner wall of the processing table through two sliders. The two swing components are located between the adjusting component and the two sliders.

[0012] The drafting mechanism is located on the top of the base and includes a pushing assembly, a transmission assembly, a rotating assembly, an adaptive pitch adjustment assembly, three pressure rollers, three abutment rollers, four slide plates, and eight slide rails. A drawing frame is fixedly installed on the outer wall of the processing table. The eight slide rails are fixedly installed on the outer walls of both ends of the drawing frame. Each slide plate is slidably installed between two slide rails. Two pressure rollers and two abutment rollers are rotatably installed on the top and bottom of two slide plates via two first rotating shafts and two second rotating shafts, respectively. Another pressure roller and another abutment roller are rotatably installed inside the drawing frame via a third rotating shaft and a fourth rotating shaft, respectively. The transmission assembly is located on the processing table. The pushing assembly is located between the adjustment assembly and the transmission assembly. The rotating assembly is located between the transmission assembly and two slide plates. A transmission roller is also rotatably installed inside the drawing frame.

The push plate is fixedly mounted between the two L-shaped rods, and the top of the push plate is fixedly connected to the output end of the electric push rod. The electric push rod is electrically connected to the controller.

[0014] Furthermore, each swing assembly includes a swing arm, a first insert rod, and a second insert rod. The swing arm is hinged to the outer wall of the processing table. The first insert rod is fixed to one end of one of the L-shaped rods away from the push plate. The second insert rod is fixed to one end of one of the sliders away from the lifting rod. The two ends of the swing arm are provided with slots for the first insert rod and the second insert rod to slide. Several second stops are provided at equal intervals on the top of the lifting rod.

[0015] Furthermore, the pushing assembly includes a first rack, a lifting plate, a wedge-shaped top block, a wedge-shaped push block, a return spring, and a slide rod.

The driven wheel is fixed at one end of the other rotating rod. The belt is sleeved between the driving wheel and the driven wheel.

[0017] Furthermore, the rotating assembly includes a turntable and two connecting rods. The turntable is fixed to the other end of another connecting rod, and each connecting rod is hinged between the outer wall of the turntable and the outer wall of one of the slides.

[0018] Furthermore, the adaptive pitch adjustment assembly includes a motor, a slide rail, a telescopic spring, a slide bar, a synchronous belt, two tension rollers, and four synchronous pulleys. The motor is fixed to the outer wall of one of the slide plates via an L-shaped plate. Both tension rollers are rotatably mounted on the outer wall of the drawing box. Three synchronous pulleys are fixed to one end of a third rotating shaft and two first rotating shafts, respectively. The slide rail is fixed to the top of the drawing box, and the slide bar slides inside the slide rail. Another synchronous pulley rotatably mounts on the outer wall of the slide bar. The synchronous belt is sleeved between the four synchronous pulleys. The telescopic spring is fixed between the top inner wall of the slide rail and the top of the slide bar.

The two ends of the drawing box are symmetrically provided with clearance grooves for the sliding of the two first rotating shafts and the two second rotating shafts. The motor is electrically connected to the controller.

[0019] Furthermore, the outer walls at both ends of the roll box are respectively provided with a feed inlet and a discharge outlet, and guide rollers are provided on the sides of both the feed inlet and the discharge outlet.

[0020] A high-count blended yarn includes a yarn body with a spiral structure identical to that of existing blended fibers, and further includes cotton fibers, honeycomb polyester, and tansil fibers. The yarn body is a blend of cotton fibers, honeycomb polyester, and tansil fibers, and the outer surfaces of the honeycomb polyester and tansil fibers are coated with an oil film.

[0021] Furthermore, the ratio of honeycomb polyester, tansil fiber, and cotton fiber is 2:1:1.

[0022] The beneficial effects of this invention are:

[0023] 1. This invention, through the design of the yarn body, which includes cotton fiber, honeycomb polyester, tansil fiber, and an oil film, effectively integrates the lightweight, soft, high-quality, and eco-friendly characteristics of tansil fiber with the antibacterial, bacteriostatic, and UV-resistant functions of honeycomb polyester. Combined with the excellent properties of cotton fiber—rapid water absorption, quick drying, and automatic temperature and humidity regulation—the oil film treatment on the surfaces of the tansil fiber and honeycomb polyester effectively avoids the drawbacks of honeycomb polyester easily generating static electricity during blending, and the tendency to produce flyaways, holes, and breaks during spinning. This improves the spinnability of both tansil fiber and honeycomb polyester, resulting in an ideal high-count blended yarn.

[0024] 2. This invention, through the design of an adjustment component, can drive several second limiting blocks to descend rapidly until they are flush with several first limiting blocks. That is, the through holes on the several second limiting blocks are at the same height as the through holes on the several first limiting blocks. This allows for flexible increase in the number of slivers combined, meeting the drawing requirements of high-count blended yarns, improving the flexibility of the device, and simultaneously improving fiber mixing, straightness, and parallelism, thereby reducing yarn defects and improving yarn quality.

[0025] 3. This invention, through the design of a pushing component, enables the coordinated operation of the feeding mechanism and the drafting mechanism. Combined with an adaptive spacing adjustment component, it can simultaneously reduce the spacing of several pressure rollers as the number of slivers combined increases, thereby increasing the drafting force and improving the drawing effect. Specifically, when the number of slivers combined increases, reducing the roller spacing helps to:

[0026] a. Improves the evenness of swabs and reduces unevenness.

[0027] b. Improve drawing efficiency and enhance control over the fibers.

[0028] c. Optimize fiber straightening and parallelism to improve yarn quality.

[0029] Therefore, by reducing the roller spacing, the increased number of slivers can be better utilized to reduce sliver weight unevenness, thereby improving the quality and uniformity of the yarn.

[0030] 4. By designing a pusher component, this invention enables the feeding mechanism and the drafting mechanism to operate in tandem. Only one electric push rod and one motor are needed to achieve synchronous operation of the two mechanisms. Compared with the prior art, this greatly reduces the number of drive sources used in the entire device, which helps to reduce power consumption and save on drawing costs. At the same time, it can reduce the overall structure of the device, which helps to reduce manufacturing and floor space, and facilitates its use in conjunction with other processes of existing drawing machines.

[0031] 5. This invention designs two swing components. While the push plate drives several second limiting blocks to descend and align with several first limiting blocks, it simultaneously drives the lifting rod to slide vertically upward. This causes several second stop bars at the top of the lifting rod to extend from inside the processing table to the top of the table. As the number of cotton slivers increases, it provides a limiting effect, preventing the conveying of multiple cotton slivers from becoming chaotic. This improves the precise conveying of cotton slivers to the splitting box, enhances the conveying effect and efficiency, and facilitates steady conveying to the drafting mechanism, enabling rapid drafting and improving the efficiency of sliver drawing.

Detailed Implementation

[0044] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0045] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0046] Reference Figures 1 to 9 As shown, a device for processing and drawing high-count blended yarns includes a base 1 and a self-adjusting leveling detection mechanism 2.

[0047] It also includes a controller, a processing table 3, a feeding mechanism 4 and a stretching mechanism 5. The processing table 3 is located on the top of the base 1, the self-adjusting and leveling detection mechanism 2 is located on the top of the processing table 3, and the top of the processing table 3 is provided with a splitting box 30.

[0048] The feeding mechanism 4 is located on the top of the processing table 3. The feeding mechanism 4 includes a lifting rod 40, an adjusting component 41, two swing components 42, several first limit blocks 43 and several second limit blocks 44. A U-shaped frame is fixedly provided on the top of the processing table 3. The adjusting component 41 is located on the U-shaped frame. Several second limit blocks 44 are evenly spaced on the adjusting component 41. Several first limit blocks 43 are evenly spaced at one end of the top of the processing table 3. Each first limit block 43 and each second limit block 44 has a through hole 430 on its outer wall. Several first stop rods 31 are evenly spaced on the top of the processing table 3. The lifting rod 40 is slidably located on the inner wall of the processing table 3 through two sliders 400. The two swing components 42 are located between the adjusting component 41 and the two sliders 400.

[0049] The drafting mechanism 5 is located on the top of the base 1. The drafting mechanism 5 includes a pushing assembly 50, a transmission assembly 51, a rotating assembly 52, an adaptive pitch adjustment assembly 53, three pressure rollers 54, three abutment rollers 55, four slide plates 56, and eight slide rails 57. A drawing box 32 is fixedly mounted on the outer wall of the processing table 3. The eight slide rails 57 are respectively fixed on the outer walls at both ends of the drawing box 32. Each slide plate 56 is slidably disposed between two slide rails 57. The two pressure rollers 54 and two abutment rollers 55 are rotatably mounted on two first rotating shafts and two second rotating shafts, respectively. The top and bottom of the slide plate 56, another pressure roller 54 and another abutment roller 55 are rotatably mounted inside the drawing frame 32 via the third rotating shaft and the fourth rotating shaft, respectively. The transmission assembly 51 is mounted on the processing table 3. The pushing assembly 50 is mounted between the adjusting assembly 41 and the transmission assembly 51. The rotating assembly 52 is mounted between the transmission assembly 51 and two of the slide plates 56. The drawing frame 322 is also rotatably mounted inside the drawing frame 32. The adaptive pitch adjustment assembly 53 is mounted between the drawing frame 32, the third rotating shaft and the two first rotating shafts. The adjusting assembly 41 is electrically connected to the controller.

[0050] Reference Figures 1 to 9As shown, the adjustment assembly 41 includes an electric push rod 410, a push plate 411, and two L-shaped rods 412. The electric push rod 410 is fixedly mounted on the outer wall of the U-shaped rod. Two guide rods are fixedly mounted at both ends of the top of the processing table 3. Each L-shaped rod 412 is slidably mounted on one guide rod. The push plate 411 is fixedly mounted between the two L-shaped rods 412, and the top of the push plate 411 is fixedly connected to the output end of the electric push rod 410. The electric push rod 410 is electrically connected to the controller. When it is necessary to increase the number of rods to be combined, the electric push rod is activated by the controller. Rod 410 extends downwards, and its output end is fixedly connected to push plate 411. Two L-shaped rods 412 are fixedly connected to both ends of push plate 411 respectively. Each L-shaped rod 412 is slidably connected to a guide rod. Several second limiting blocks 44 are fixedly connected to push plate 411, thereby driving several second limiting blocks 44 to descend vertically until they are flush with several first limiting blocks 43, that is, the through holes 430 on several second limiting blocks 44 are horizontal with the through holes 430 on several first limiting blocks 43.

[0051] Reference Figures 1 to 9 As shown, each swing assembly 42 includes a swing rod 420, a first insert rod 421, and a second insert rod 422. The swing rod 420 is hinged to the outer wall of the processing table 3. The first insert rod 421 is fixedly mounted on one end of an L-shaped rod 412 away from the push plate 411. The second insert rod 422 is fixedly mounted on one end of a slider 400 away from the lifting rod 40. The two ends of the swing rod 420 have slots for the first insert rod 421 and the second insert rod 422 to slide. The top of the lifting rod 40 has several second stop rods 423 spaced evenly. When the through holes 430 on several second limit blocks 44 and the through holes 430 on several first limit blocks 43 are horizontal, due to… The swing arm 420 is hinged to the processing table 3. The first insertion rod 421 is fixedly connected to one end of an L-shaped rod 412 away from the push plate 411. The second insertion rod 422 is fixedly connected to one end of a slider 400 away from the lifting rod 40. The two ends of the swing arm 420 are provided with slots for the first insertion rod 421 and the second insertion rod 422 to slide. The top of the lifting rod 40 is fixedly connected to several second stop rods 423. Thus, the lifting rod 40 drives several second stop rods 423 to slide upward from the inside of the processing table 3 until they are level with several first stop rods 31. This ensures that the added cotton strips can be limited by several second stop rods 423, which is beneficial to improving the effect of cotton strip merging and conveying.

[0052] Reference Figures 1 to 9As shown, the pushing assembly 50 includes a first rack 500, a lifting plate 501, a wedge-shaped top block 502, a wedge-shaped push block 503, a return spring 504, and a slide rod 505. The lifting plate 501 is fixedly mounted on the top of one of the L-shaped rods 412. The wedge-shaped top block 502 is fixedly mounted on the bottom end of the lifting plate 501 away from the L-shaped rod 412 by two connecting rods. An mounting plate is fixedly mounted on the outer wall of the processing table 3. The slide rod 505 is slidably mounted on the mounting plate by a limiting plate. At the top, a wedge-shaped push block 503 is fixedly mounted on one end of the slide rod 505 near the wedge-shaped top block 502. The wedge-shaped push block 503 and the wedge-shaped top block 502 are slidably connected. A return spring 504 is sleeved on the outer wall of the slide rod 505. The wedge-shaped push block 503 and the limiting plate respectively abut against the two ends of the return spring 504. A first rack 500 is fixedly mounted on one end of the slide rod 505 away from the wedge-shaped push block 503. A guide rail is fixedly mounted on the top of the mounting plate. The first rack 500 is connected to the guide rail. In a sliding connection, as several second stop bars 423 slide upward from the inside of the processing table 3 until they are level with several first stop bars 31, the lifting plate 501 and the push plate 411 are fixedly connected through one of the L-shaped rods 412. The wedge-shaped top block 502 is fixedly connected to the bottom end of the lifting plate 501 away from the L-shaped rod 412 through two connecting rods. One end of the wedge-shaped push block 503 is fixedly connected to the slide rod 505, and the other end of the slide rod 505 is fixedly connected to the first rack 500. The other end of the wedge-shaped push block 503 slides and remains in contact with the wedge-shaped top block 502. Thus, when the push plate 411 drives the wedge-shaped top block 502 to descend, the resistance force generated on the wedge-shaped push block 503 is converted into the pushing force of the wedge-shaped push block 503 on the first rack 500. This causes the first rack 500 to slide away from the top of the guide rail towards the end away from the wedge-shaped top block 502. During this process, the return spring 504 changes from the initial state to the contracted state.

[0053] Reference Figures 1 to 9 As shown, two rotating rods are rotatably mounted on the outer wall of the processing table 3. The transmission assembly 51 includes a first gear 510, a driving wheel 511, a driven wheel 512, and a belt 513. The first gear 510 and the driving wheel 511 are respectively fixed at both ends of one of the rotating rods. The first gear 510 is meshed with the first rack 500. The driven wheel 512 is fixed at one end of the other rotating rod. The belt 513 is sleeved between the driving wheel 511 and the driven wheel 512. When the first rack 500 slides away from the wedge-shaped top block 502 at the top of the guide rail, the first gear 510 and the first rack 500 are meshed. The first gear 510 and the driving wheel 511 are respectively fixedly connected to both ends of one of the rotating rods. The driven wheel 512 is fixedly connected to the other rotating rod. The driving wheel 511 and the driven wheel 512 are sleeved through the belt 513, thereby driving the other rotating rod to rotate clockwise.

[0054] Reference Figures 1 to 9As shown, the rotating assembly 52 includes a turntable 520 and two connecting rods 521. The turntable 520 is fixedly mounted on the other end of another rotating rod. Each connecting rod 521 is hinged between the outer wall of the turntable 520 and the outer wall of one of the sliding plates 56. When the other rotating rod rotates clockwise, since the end of the other rotating rod away from the driven wheel 512 is fixedly connected to the turntable 520, the outer wall of the turntable 520 and the outer wall of one of the sliding plates 56 are respectively hinged to the two ends of each connecting rod 521. Each sliding plate 56 is slidably connected to two of the slide rails 57. The two pressure rollers 54 and the two abutment rollers 55 are rotatably connected to the top and bottom of the two sliding plates 56 through two first rotating shafts and two second rotating shafts, respectively, thereby driving the four sliding plates 56 located on both sides and the two pressure rollers 54 and two abutment rollers 55 on their outer walls to move closer to each other.

[0055] Reference Figures 1 to 9As shown, the adaptive pitch adjustment assembly 53 includes a motor 530, a slide rail 531, a telescopic spring 532, a slide bar 533, a synchronous belt 534, two tension rollers 535, and four synchronous pulleys 536. The motor 530 is fixed to the outer wall of one of the slide plates 56 via an L-shaped plate. Both tension rollers 535 are rotatably mounted on the outer wall of the drawing box 32. Three synchronous pulleys 536 are respectively fixed to one end of the third rotating shaft and one end of the two first rotating shafts. The slide rail 531 is fixed to the top of the drawing box 32, and the slide bar 533 slides inside the slide rail 531. A synchronous pulley 536 is rotatably mounted on the outer wall of the slide bar 533. A synchronous belt 534 is sleeved between the four synchronous pulleys 536. A telescopic spring 532 is fixedly mounted between the top inner wall of the slide rail 531 and the top of the slide bar 533. A second gear 537 is fixedly mounted at one end of the third shaft and each of the first shafts, and a third gear 538 is fixedly mounted at one end of the third shaft and each of the second shafts. Each second gear 537 meshes with a third gear 538, and the diameter of each second gear 537 is smaller than the diameter of a third gear 538. The two ends of 32 are symmetrically provided with clearance grooves 321 for sliding of two first rotating shafts and two second rotating shafts. The motor 530 is electrically connected to the controller. When the four slide plates 56 on both sides and the two pressure rollers 54 and two abutment rollers 55 on their outer walls approach each other, the telescopic spring 532 is initially in a stretched state. As the four slide plates 56 approach each other, the telescopic spring 532 changes from stretched to contracted state, thereby pulling the slide bar 533 so that the synchronous pulley 536 on its outer wall moves along the slide rail 531. While the roller spacing is adjusted to be smaller, it ensures that the synchronous belt 534 is always... The yarn is in a taut state and will not slack off. Then, the controller starts the motor 530. With the cooperation of the synchronous belt 534, two tensioning rollers 535 and four synchronous pulleys 536, the three pressure rollers 54 are driven to rotate clockwise. In cooperation with the transmission roller 320 and three abutment rollers 55, the speed difference between the three pressure rollers 54 and the three abutment rollers 55 is used to stretch multiple cotton slivers of different materials. By reducing the roller spacing, the movement of the fibers can be better controlled, thereby improving the drafting efficiency and the parallel straightness of the fibers, and further improving the yarn quality.

[0056] Reference Figures 1 to 9As shown, the two ends of the drawing box 32 are respectively provided with a feed inlet 322 and a discharge outlet 323. Guide rollers 324 are provided on the sides of both the feed inlet 322 and the discharge outlet 323. When drawing is required, cotton slivers of three materials, namely cotton fiber 60, honeycomb polyester 61 and tansil fiber 62, are passed through the first limiting blocks 43 between several first stop bars 31 in the corresponding proportions, and then pass through the splitting box 30, the self-adjusting and leveling detection mechanism 2, the transmission roller 320, the three pressure rollers 54 and the three abutment rollers 55 in sequence. The yarn passes through the outlet 323 and then the motor 530 is started, driving the three pressure rollers 54 to rotate counterclockwise. In cooperation with the transmission roller 320 and the three abutment rollers 55, the yarn body 6 is stretched by the rotational speed difference between the three pressure rollers 54 and the three abutment rollers 55 to achieve the required fineness and uniformity. The two guide rollers 324 play a guiding role, which helps to improve the drawing effect. The stretched sliver is then sent into the bundler for preliminary gathering of the fiber web, preparing for subsequent forming and winding.

[0057] A high-count blended yarn includes a yarn body 6, the spiral structure of which is the same as that of existing blended fiber spirals. It also includes cotton fiber 60, honeycomb polyester 61, and tansil fiber 62. The yarn body 6 is a blend of cotton fiber 60, honeycomb polyester 61, and tansil fiber 62. The outer surfaces of the honeycomb polyester 61 and tansil fiber 62 are coated with an oil film 63 for pre-spinning preparation. Since honeycomb polyester 61 and tansil fiber 62 are prone to static electricity, pre-treatment is necessary to overcome this static. An appropriate amount of oil is sprayed on the fibers, and the yarn is left to stand for 24 hours before winding. Because the oil contains a certain amount of moisture and antistatic agent, the fibers achieve a certain moisture regain, reducing static electricity generated by friction and improving the spinnability of the two fibers to ensure smooth production. After the yarn body 6 is cleaned and carded, it enters the drawing process.

[0058] Reference Figure 9 As shown, the ratio of honeycomb polyester 61, tansil fiber 62 and cotton fiber 60 is 2:1:1. This ratio can improve the mixing effect of the three materials, making it easier to draw the yarn later.

[0059] The working principle of this invention is as follows: Before spinning, the honeycomb polyester 61 and tansil fiber 62 are prone to static electricity, so they must be pretreated to overcome the static electricity. An appropriate amount of oil is sprayed on them and left for 24 hours before rolling them up for use. Since the oil contains a certain amount of water and antistatic agent, the fibers reach a certain moisture regain rate, which can reduce the static electricity generated by friction and improve the spinnability of the two fibers to ensure smooth production. After the yarn body 6 is cleaned and carded, it enters the drawing process.

[0060] The ratio of honeycomb polyester 61, tansil fiber 62 and cotton fiber 60 is designed to be 2:1:1. This ratio can improve the mixing effect of the three materials and facilitate subsequent drawing.

[0061] When drawing is required, cotton slivers of three materials—cotton fiber 60, honeycomb polyester 61, and tansil fiber 62—are passed through the first limiting blocks 43 between several first stop bars 31 in corresponding proportions. They then pass through the splitting box 30, the self-adjusting leveling detection mechanism 2, the drive roller 320, three pressure rollers 54, and three abutment rollers 55 in sequence until they exit from the discharge port 323. Then, the motor 530 is started, driving the three pressure rollers 54 to rotate counterclockwise. In conjunction with the drive roller 320 and the three abutment rollers 55, the rotational speed difference between the three pressure rollers 54 and the three abutment rollers 55 is used to stretch the yarn body 6 to achieve the required fineness and uniformity. The two guide rollers 324 play a guiding role, which helps to improve the drawing effect. The stretched cotton slivers are then sent into the bundler for preliminary fiber web gathering, preparing for subsequent forming and winding.

[0062] When it is necessary to improve the uniformity of the sliver or the quality of the yarn, or when it is necessary to increase the number of slivers to be combined, the electric push rod 410 is activated by the controller, so that its output end extends downward. Since its output end is fixedly connected to the push plate 411, the two L-shaped rods 412 are fixedly connected to the two ends of the push plate 411 respectively. Each L-shaped rod 412 is slidably connected to a guide rod. Several second limit blocks 44 are fixedly connected to the push plate 411, thereby driving several second limit blocks 44 to descend vertically until they are flush with several first limit blocks 43, that is, the through holes 430 on several second limit blocks 44 are horizontal with the through holes 430 on several first limit blocks 43.

[0063] While the through holes 430 on several second limiting blocks 44 and the through holes 430 on several first limiting blocks 43 are horizontal, the swing rod 420 is hinged to the processing table 3, the first insert rod 421 is fixedly connected to one of the L-shaped rods 412 away from the push plate 411, and the second insert rod 422 is fixedly connected to one of the sliders 400 away from the lifting rod 40. The two ends of the swing rod 420 are provided with slots for the first insert rod 421 and the second insert rod 422 to slide. The top of the lifting rod 40 is fixedly connected to several second stop rods 423. Thus, the lifting rod 40 drives several second stop rods 423 to slide upward from the inside of the processing table 3 until they are level with several first stop rods 31. This ensures that the added cotton strips can be limited by several second stop rods 423, which is beneficial to improving the effect of cotton strip merging and conveying.

[0064] As several second stop levers 423 slide upward from inside the processing table 3 until they are level with several first stop levers 31, the lifting plate 501 and the push plate 411 are fixedly connected through one of the L-shaped rods 412. The wedge-shaped top block 502 is fixedly connected to the bottom end of the lifting plate 501 away from the L-shaped rod 412 through two connecting rods. One end of the wedge-shaped push block 503 is fixedly connected to the slide rod 505. The other end of the slide rod 505 is fixedly connected to the first rack 500. The other end of the wedge-shaped push block 503 slides and remains in contact with the wedge-shaped top block 502. Thus, when the push plate 411 drives the wedge-shaped top block 502 to descend, the resistance force generated on the wedge-shaped push block 503 is converted into the pushing force of the wedge-shaped push block 503 on the first rack 500. This causes the first rack 500 to slide away from the top of the guide rail towards the end away from the wedge-shaped top block 502. During this process, the return spring 504 changes from the initial state to the contracted state.

[0065] When the first rack 500 slides away from the wedge-shaped block 502 at the top of the guide rail, the first gear 510 and the first rack 500 are meshed together. The first gear 510 and the driving wheel 511 are fixedly connected to the two ends of one of the rotating rods respectively, and the driven wheel 512 is fixedly connected to the other rotating rod. The driving wheel 511 and the driven wheel 512 are connected by a belt 513, which in turn drives the other rotating rod to rotate clockwise.

[0066] When another rotating rod rotates clockwise, since the end of the other rotating rod away from the driven wheel 512 is fixedly connected to the turntable 520, the outer wall of the turntable 520 and the outer wall of one of the slide plates 56 are respectively hinged to the two ends of each connecting rod 521. Each slide plate 56 is slidably connected to two of the slide rails 57. The two pressure rollers 54 and the two abutting rollers 55 are rotatably connected to the top and bottom of the two slide plates 56 through two first rotating shafts and two second rotating shafts, respectively, thereby driving the four slide plates 56 located on both sides and the two pressure rollers 54 and two abutting rollers 55 on their outer walls to move closer to each other.

[0067] When the four sliding plates 56 on both sides and the two pressure rollers 54 and two abutment rollers 55 on their outer walls approach each other, the tension spring 532, initially in a stretched state, changes from stretched to contracted as the four sliding plates 56 approach each other. This pulls the slide bar 533 so that the synchronous wheel 536 on its outer wall moves along the slide rail 531. While the roller spacing is reduced, the synchronous belt 534 is kept taut and will not slack. Then, the motor 530 is started by the controller. With the cooperation of the synchronous belt 534, the two tension rollers 535 and the four synchronous wheels 536, the three pressure rollers 54 are driven to rotate clockwise. In cooperation with the transmission roller 320 and the three abutment rollers 55, the speed difference between the three pressure rollers 54 and the three abutment rollers 55 is used to stretch multiple cotton slivers of different materials. By reducing the roller spacing, the movement of the fibers can be better controlled, thereby improving the drafting efficiency and the parallel straightness of the fibers, and further improving the yarn quality.
