Abstract

This utility model relates to the field of fabric processing auxiliary devices, specifically to a yarn separating device for processing high-twist jacquard fabrics with different warp widths. It includes a vertical plate, a pitch-changing mechanism, and a positioning mechanism. The pitch-changing mechanism includes an adjusting plate, a driving component, a traction component, and several sliding plates.

Description

Technical Field

[0001] This utility model relates to the field of fabric processing auxiliary devices, specifically to a yarn separating device for processing high-twist jacquard fabrics. Background Technology

[0002] High-twist jacquard fabric refers to fabric woven from multiple high-twist yarns. High-twist fabrics are extremely durable, with a lifespan far exceeding that of other traditional fabrics. This means we don't need to replace clothes as frequently, thus reducing resource waste. Its versatility is also a significant advantage. Whether making sportswear, casual wear, or high-end suits, high-twist fabrics can handle it all with ease. Especially in summer, garments made from high-twist fabrics are breathable, effectively absorbing sweat and keeping the wearer dry. Even in hot weather, they provide a cool and comfortable feel. In contrast, other ordinary fabrics can easily cause discomfort in such high temperatures, while the comfort of high-twist fabrics is reflected in these details, like a gentle breeze – a true savior for summer wardrobes.

[0003] The existing technology has the following shortcomings:

[0004] 1. In the processing of existing jacquard fabrics with different warp twists, the warp shrinkage rate differs due to the different thicknesses of the two types of twisted yarns. In addition, the tension of the two types of warp yarns differs, which can easily lead to an increase in warp breakage at the twist ends and difficulties in weft insertion.

[0005] 2. During the forward conveying process of fabric production, yarn is prone to adhering to the surface of the yarn, such as thread ends. When a large amount of impurities accumulate, manual cleaning is time-consuming and laborious. If not cleaned in time, it will affect the conveying efficiency of the yarn, thereby reducing the yarn's twist quality and efficiency, and further reducing the fabric production quality. Utility Model Content

[0006] The purpose of this invention is to provide a yarn separating device for processing jacquard fabrics with different warp twists.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] A yarn separating device for processing high-twist jacquard fabrics with different warp widths is provided, including a vertical plate;

[0009] It also includes pitch control mechanisms and positioning mechanisms;

[0010] The pitch-changing mechanism is located on the outer wall of the upright plate. The pitch-changing mechanism includes an adjusting plate, a driving assembly, a traction assembly, and several sliding plates. Two guide rods are fixedly installed on the outer wall of the upright plate, and several sliding plates are slidably installed on the outer wall of the two guide rods. The driving assembly is located on the outer wall of the upright plate, the adjusting plate is located between the driving assembly and one of the sliding plates, and the traction assembly is located between the several sliding plates.

[0011] The positioning mechanism is located on the pitch-changing mechanism. The positioning mechanism includes several mounting plates, several locking plates, and several adjusting components. Each mounting plate is detachably mounted on the bottom of a sliding plate. Each locking plate is fixedly mounted on a mounting plate. Several adjusting components are located between the mounting plates and the locking plates.

[0012] Preferably, the drive assembly includes a stepper motor, a synchronous belt, a lead screw, a slider, and two synchronous pulleys. A U-shaped plate is fixedly mounted on the outer wall of the upright plate. The lead screw is rotatably mounted on the U-shaped plate. The stepper motor is fixedly mounted on the upright plate. The two synchronous pulleys are respectively fixedly mounted on the output ends of the lead screw and the stepper motor. The synchronous belt is sleeved on the outer wall of the two synchronous pulleys. The slider is slidably mounted on the outer wall of the U-shaped plate. The slider is threadedly connected to the lead screw, and one end of the slider is fixedly connected to the adjustment plate.

[0013] Preferably, the traction assembly includes four first links and six second links. The four first links are respectively hinged to the outer walls of two mutually distant slides, and every two links on the same side are hinged together. The six second links are hinged between the four first links, and the centers of every two second links are hinged together. One end of each first link is hinged to one end of one of the second links.

[0014] Preferably, each adjusting component includes a locking tooth, a slide rod, a telescopic spring, a slide bar, a mounting plate, and a combing plate. A slide rail is fixedly provided on the outer wall of each mounting plate. The slide bar is slidably disposed on the slide rail. The slide rod is slidably disposed on the outer wall of the slide bar. The mounting plate is fixedly disposed at the bottom of the slide rod. The combing plate is fixedly disposed at the bottom of the mounting plate. The locking tooth is fixedly disposed at the top of the slide rod. The telescopic spring is sleeved on the outer wall of the slide rod. A flange is fixedly provided on the outer wall of the slide rod. The bottom of the flange and the top of the slide bar respectively abut against the two ends of the telescopic spring.

[0015] Preferably, each locking plate has several locking grooves at equal intervals on its outer wall for locking teeth to engage.

[0016] Preferably, a limiting strip is fixedly provided on the outer wall of the slide bar, and a guide groove is provided on the outer wall of the slide bar for the limiting strip to pass through.

[0017] Preferably, each mounting plate is fixedly connected to the bottom of a slide plate by two bolts.

[0018] Preferably, each slide is slidably connected to two guide rods via two sliding bearings.

[0019] The beneficial effects of this utility model are:

[0020] 1. This utility model, through the design of a positioning mechanism, namely several mounting plates, several locking plates and several adjusting components, can flexibly adjust the spacing between every two adjacent carding plates to meet the diameter dimensions of the two types of high-twist yarns used to process the fabric. In other words, by having several carding plates tightly adhere the two types of high-twist yarns, the warp yarns are separated and positioned, thereby preventing warp misalignment and ensuring that the two types of high-twist yarns of different thicknesses are evenly arranged. At the same time, it can prevent warp breakage and increased weft insertion difficulties caused by differences in the tightness of the multiple warp yarns, which is beneficial to improving the processing quality of jacquard fabrics.

[0021] 2. This utility model designs a variable-pitch mechanism, namely an adjusting plate, a driving assembly, a traction assembly, and several sliding plates. The adjusting plate, in conjunction with four first connecting rods and six second connecting rods, drives the sliding plates to move closer or further apart, causing several yarns to split apart from the center. This allows impurities such as thread ends that adhere to the carding plates and yarns to be shaken off through the split gaps. The lead screw, in conjunction with a stepper motor, can precisely control the sliding distance of the adjusting plate, thereby adjusting the degree of yarn splitting. This achieves the goal of shaking off impurities without affecting the yarn feeding and carding. It should be noted that when the carding plates are not split apart, they work in conjunction with the multiple warp yarns being fed forward to card the yarns, removing thread ends and other impurities from the yarn surface, thus improving the purity of the yarns. This ensures that the woven jacquard fabric is beautiful and neat, while also minimizing the shrinkage rate of the multiple warp yarns.

[0022] 3. This utility model uses a bolt design to connect the mounting plate and the slide plate. When the mounting plate is damaged, it can be quickly removed from the outer wall of the slide plate, making it easy to replace with a new mounting plate quickly. This eliminates the need to discard the entire positioning mechanism, avoids waste, and helps improve the maintenance efficiency of the device and reduce maintenance costs.

[0030] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] 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.

[0032] Reference Figures 1 to 5 As shown, a yarn separating device for processing high-twist jacquard fabrics includes a vertical plate 1;

[0033] It also includes pitch control mechanisms and positioning mechanisms;

[0034] The pitch-changing mechanism is located on the outer wall of the upright plate 1. The pitch-changing mechanism includes an adjusting plate 2, a driving assembly, a traction assembly, and several sliding plates 3. Two guide rods 4 are fixedly installed on the outer wall of the upright plate 1. Several sliding plates 3 are slidably installed on the outer wall of the two guide rods 4. The driving assembly is located on the outer wall of the upright plate 1. The adjusting plate 2 is located between the driving assembly and one of the sliding plates 3. The traction assembly is located between several sliding plates 3.

[0035] The positioning mechanism is located on the pitch-changing mechanism. The positioning mechanism includes several mounting plates 5, several locking plates 6, and several adjusting components. Each mounting plate 5 is detachably mounted on the bottom of a sliding plate 3. Each locking plate 6 is fixedly mounted on a mounting plate 5. Several adjusting components are located between the mounting plates 5 and the locking plates 6.

[0036] Reference Figures 1 to 5As shown, the drive assembly includes a stepper motor 7, a synchronous belt 8, a lead screw 9, a slider 10, and two synchronous pulleys 11. A U-shaped plate is fixedly mounted on the outer wall of the upright plate 1. The lead screw 9 is rotatably mounted on the U-shaped plate. The stepper motor 7 is fixedly mounted on the upright plate 1. The two synchronous pulleys 11 are respectively fixedly mounted on the output ends of the lead screw 9 and the stepper motor 7. The synchronous belt 8 is sleeved on the outer wall of the two synchronous pulleys 11. The slider 10 is slidably mounted on the outer wall of the U-shaped plate. The slider 10 is threadedly connected to the lead screw 9, and one end of the slider 10 is fixedly connected to the adjusting plate 2. This device is equipped with a controller, and all electrical devices on the device are electrically connected to the controller. This device is designed for use with existing high-twist jacquard fabric processing machinery, and can be arranged along the warp direction of the processing machinery. In the yarn conveying path, when multiple high-twist yarns are processed into jacquard fabrics, impurities such as thread ends will adhere to the outer wall of the warp yarns. When a large amount of impurities accumulate, manual cleaning is time-consuming and laborious. If not cleaned in time, it will affect the conveying efficiency of the yarn, thereby reducing the high-twist quality and efficiency of the yarn. When this situation occurs, the stepper motor 7 is started by the controller, which drives one of the synchronous pulleys 11 to rotate through the output end of the stepper motor 7. Since the other synchronous pulley 11 is fixedly connected to the lead screw 9, the two synchronous pulleys 11 are connected by the synchronous belt 8. The slider 10 is threadedly connected to the lead screw 9 and slidably connected to the U-shaped plate. One of the sliding plates 3 is fixedly connected to the slider 10 through the adjusting plate 2, thereby driving the adjusting plate 2 to slide horizontally.

[0037] Reference Figures 1 to 5As shown, the traction assembly includes four first links 12 and six second links 13. The four first links 12 are respectively hinged to the outer walls of two mutually distant sliding plates 3, with each pair of links on the same side being hinged together. The six second links 13 are hinged between the four first links 12, with the centers of each pair of second links 13 being hinged together. One end of each first link 12 is hinged to one end of one of the second links 13. When the adjusting plate 2 slides horizontally, because the four first links 12 are respectively hinged to the outer walls of two mutually distant sliding plates 3, with each pair of links on the same side being hinged together, and the six second links 13 are hinged between the four first links 12, with the centers of each pair of second links 13 being hinged together, and one end of each first link 12 is hinged to one end of one of the second links 13, when the adjusting plate 2 slides horizontally, the traction assembly is assisted by the hinged design. One end of the two connecting rods 13 is hinged, and through the adjustment plate 2, in conjunction with the four first connecting rods 12 and the six second connecting rods 13, several sliding plates 3 are driven to move closer or further apart, so that several yarns can be separated from the middle to both sides. This allows the scraped-off impurities such as thread ends adhering between the carding plate 19 and the yarns to be shaken off through the gaps. The lead screw 9, in conjunction with the stepper motor 7, can precisely control the sliding distance of the adjustment plate 2, thereby adjusting the degree of yarn separation. This achieves the goal of shaking off impurities without affecting the yarn feeding and carding. It should be noted that when the several carding plates 19 are not driven to separate, the several carding plates 19 cooperate with the multiple warp yarns being fed forward to card the yarns and scrape off impurities such as thread ends from the yarn surface. At the same time, it can also minimize the shrinkage rate of the multiple warp yarns.

[0038] Reference Figures 1 to 5As shown, each adjusting component includes a locking tooth 14, a slide rod 15, a telescopic spring 16, a slide bar 17, a mounting plate 18, and a combing plate 19. A slide rail 20 is fixedly provided on the outer wall of each mounting plate 5. The slide bar 17 slides on the slide rail 20, the slide rod 15 slides on the outer wall of the slide bar 17, the mounting plate 18 is fixedly provided at the bottom of the slide rod 15, the combing plate 19 is fixedly provided at the bottom of the mounting plate 18, the locking tooth 14 is fixedly provided at the top of the slide rod 15, and the telescopic spring 16... A flange 21 is fixedly provided on the outer wall of the slide bar 15, and the bottom of the flange 21 and the top of the slide bar 17 respectively abut against the two ends of the extension spring 16. Because the thickness of the multiple high-twist yarns used to process the fabric varies when processing heterogeneous high-twist jacquard fabric, the spacing between each pair of carding plates 19 also varies. To meet the yarn separation requirements of multiple high-twist yarns of different thicknesses, the carding plates 19 are manually grasped and pulled downwards, thereby... The carding plate 19 drives the mounting plate 18 and the slide bar 15 to slide vertically down the outer wall of the slide bar 17. The extension spring 16 changes from the initial state to the taut state under the action of the flange 21. At the same time, the locking tooth 14, which is fixedly connected to the top of the slide bar 15, slides out from the inside of the initial locking groove 22. Then, the carding plate 19 is dragged horizontally to another adjacent carding plate 19. When it slides to the side of another carding plate 19 and the distance between the two carding plates 19 meets the diameter of the high-twist yarn that needs to be separated, the worker releases the carding plate 19. As a result, the slide bar 15 pushes the locking tooth 14 into the corresponding locking groove 22 under the reset action of the extension spring 16, thereby achieving the locking effect on the adjusted carding plate 19. This prevents warp misalignment and ensures that the high-twist yarns of different thicknesses are evenly arranged. At the same time, it can prevent the warp head from breaking due to the difference in tension of multiple yarns in the warp direction and increase the difficulty of weft insertion, which is beneficial to improving the processing quality of jacquard fabrics.

[0039] Reference Figures 1 to 5 As shown, each locking plate 6 has several locking grooves 22 evenly spaced on its outer wall for locking teeth 14 to engage with. The evenly spaced locking grooves 22 ensure that the carding plate 19 can be precisely engaged after each lateral sliding adjustment, ensuring the locking effect of the locking plate 6 on the carding plate 19 after adjustment. At the same time, it can meet the yarn separation requirements of high-twist yarns of different thicknesses, improving the practicality and flexibility of the device.

[0040] Reference Figures 1 to 5 As shown, a limiting strip 23 is fixedly provided on the outer wall of the slide bar 15, and a guide groove is provided on the outer wall of the slide bar 17 for the limiting strip 23 to pass through. The limiting strip 23 and the guide groove slide in a sliding fit to ensure that the slide bar 15 will not rotate when it slides down, thereby ensuring that the locking tooth 14 slides out of the locking groove 22 along with the slide bar 15 as it slides down vertically, which is beneficial to improving the adjustment rate of the combing plate 19.

[0041] Reference Figures 1 to 5 As shown, each mounting plate 5 is fixedly connected to the bottom of a sliding plate 3 by two bolts 24. The design of connecting the mounting plate 5 and the sliding plate 3 by bolts 24 allows the mounting plate 5 to be quickly removed from the outer wall of the sliding plate 3 when it is damaged, facilitating the quick replacement of a new mounting plate 5. This avoids the need to discard the entire positioning mechanism, thus preventing waste and improving the maintenance efficiency of the device and reducing maintenance costs.

[0042] Reference Figures 1 to 5 As shown, each slide plate 3 is slidably connected to two guide rods 4 via two sliding bearings 25. The sliding bearings 25 are designed to ensure that the slide plate 3 slides smoothly between the two guide rods 4, thereby driving several carding plates 19 to slide smoothly and improving the carding effect of the yarn.
