Description

Technical Field

[0001] This utility model relates to the field of covered yarn processing technology, specifically a covered yarn twisting and positioning structure. Background Technology

[0002] Covered yarn is a new type of yarn with a core of filament or staple fiber, wrapped with another type of filament or staple fiber yarn. Its characteristics include evenness, fullness, smoothness, low fuzziness, high strength, and low breakage. Covered yarn has wide applications in the textile industry, especially suitable for knitted fabrics requiring high elasticity, such as sportswear, swimwear, and skiwear.

[0003] Twisting is the process of twisting fibers or yarns together through rotational motion, causing them to interlock and form yarn or ply. During twisting, one complete rotation of the fiber around its own axis is called one "twist." The number of twists per unit length is called the twist degree. The direction of the twist can be represented by the English letters Z or S, referred to as Z-twist or S-twist respectively, also known as right-hand twist or left-hand twist.

[0004] Conventional twisting and positioning of covered yarn involves feeding the yarn using a roller structure while utilizing its structural characteristics to assist in positioning and guiding multiple strands of yarn. However, considering the situation of some roller structures, unnecessary interference may occur between multiple strands of yarn during the yarn feeding process, thus affecting subsequent twisting operations.

[0005] Therefore, in view of this, we studied and improved the existing structure and its shortcomings, and proposed a twisted positioning structure for the covered yarn. Summary of the Invention

[0006] The purpose of this invention is to provide a twisting and positioning structure for covered yarns to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a twisting and positioning structure for covered yarn, comprising a roller assembly and a first positioning assembly. The first positioning assembly is mounted on one side of the roller assembly, and a second positioning assembly is mounted on the side of the roller assembly away from the first positioning assembly. A stabilizing frame is connected to the bottom of the side of the roller assembly near the second positioning assembly, and a twisting assembly is installed in the middle of the stabilizing frame. The first positioning assembly includes a fixed frame, a first stabilizing rod, a first movable member, and a first positioning ring. The first stabilizing rod is horizontally mounted on the side of the fixed frame away from the roller assembly, and a first movable member is mounted on the surface of the first stabilizing rod. A first positioning ring is mounted on the upper end of the first movable member.

[0008] Furthermore, the roller assembly includes an upper roller, an upper drive bearing housing, a lower roller, a lower drive bearing housing, and a bidirectional lead screw. The upper roller is connected to the upper drive bearing housing at both its left and right ends, and the lower roller is mounted directly below the upper roller. The lower roller is connected to the lower drive bearing housing at both its left and right ends, and the bidirectional lead screw is vertically threaded onto both ends of the lower drive bearing housing and the upper drive bearing housing.

[0009] Furthermore, the lower roller and the upper roller have the same structure, and the upper roller and the lower roller are arranged in a parallel structure. Moreover, three sets of the upper roller and the lower roller are installed at equal intervals along the sides of the upper drive bearing seat and the lower drive bearing seat, respectively.

[0010] Furthermore, the first stabilizer bar and the fixed frame are movably connected, and the first movable member is slidably mounted on the surface of the first stabilizer bar, while the first movable member and the first positioning ring are fixedly connected.

[0011] Furthermore, the second positioning component includes a second stabilizer bar, a telescopic frame, a second movable member, and a second positioning ring. The telescopic frame is movably mounted on both the left and right ends of the second stabilizer bar, and the second movable member is mounted on the surface of the second stabilizer bar. The second positioning ring is provided at the end of the second movable member away from the second stabilizer bar.

[0012] Furthermore, the second positioning ring and the first positioning ring have the same structure, and the second positioning ring and the second movable member are integrally formed. The second movable member is slidably connected to the middle section surface of the second stabilizer rod, and one end of the telescopic frame is horizontally installed on one end of the lower drive bearing seat.

[0013] Furthermore, the twisting assembly includes a first servo motor, a rotary frame, a second servo motor, a winding roller, and a guide ring. The top power output end of the first servo motor is mounted on the rotary frame via a coupling, and the second servo motor is horizontally mounted on one side of the rotary frame. The power output end of the second servo motor is mounted on the winding roller via a coupling, and a guide ring is mounted directly above the winding roller.

[0014] Furthermore, the guide ring is fixedly connected to the rotary frame, and the winding roller is horizontally mounted in the middle of the inner side of the rotary frame.

[0015] This utility model provides a twisting and positioning structure for coated yarns, which has the following beneficial effects:

[0016] 1. This utility model, by mounting a first positioning component and a second positioning component at the front and rear ends of a roller assembly respectively, includes a first movable component and a second movable component slidably connected to the surfaces of a first stabilizing rod and a second stabilizing rod respectively. Multiple sets of the first and second movable components can be installed within a certain range on the surfaces of the first and second stabilizing rods according to processing needs. Simultaneously, the structural mobility between the first and second movable components and the first and second stabilizing rods allows for horizontal adjustment or rotation adjustment at a certain angle around the first and second stabilizing rods, thereby appropriately adjusting the structure of the first and second positioning rings. This ensures that each strand of yarn passing through a set of first and second positioning rings maintains an effective distance from each other, preventing unnecessary entanglement and interference between yarns during transport. This assists the roller assembly in stably transporting the yarn while also allowing for appropriate adjustment based on the number of yarn strands, thus ensuring the flexibility and practicality of the device structure.

[0017] 2. This utility model features a bidirectional lead screw symmetrically and vertically installed on the sides of the upper and lower drive bearing seats, respectively, away from the upper and lower rollers. This bidirectional lead screw structure provides structural connection between the upper and lower drive bearing seats. When the bidirectional lead screw is vertically rotated, both the upper and lower drive bearing seats simultaneously move vertically along the surface of the lead screw within a certain distance, thereby driving the upper and lower rollers to move vertically. This structure allows for appropriate adjustment of the relative distance between the upper and lower rollers according to the yarn's structural dimensions, further ensuring the flexibility of the device structure. Furthermore, since the second positioning component is connected to the roller assembly via a telescopic frame, the entire second positioning component can be adjusted horizontally by extending and retracting the telescopic frame, maintaining an appropriate positional distance between the second positioning ring and the lower second positioning ring to ensure the effectiveness of subsequent yarn processing.

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0025] like Figures 1 to 5As shown, a twisting and positioning structure for covered yarn includes a roller assembly 1 and a first positioning assembly 2. The first positioning assembly 2 is mounted on one side of the roller assembly 1, and a second positioning assembly 3 is mounted on the side of the roller assembly 1 away from the first positioning assembly 2. A stabilizing frame 4 is connected to the bottom of the roller assembly 1 near the second positioning assembly 3, and a twisting assembly 5 is installed in the middle of the stabilizing frame 4. The first positioning assembly 2 includes a fixed frame 201, a first stabilizing rod 202, a first movable part 203, and a first positioning ring 204. The fixed frame 201 is located away from the roller assembly 1. A first stabilizing rod 202 is horizontally mounted on one side of the frame, and a first movable member 203 is mounted on the surface of the first stabilizing rod 202. A first positioning ring 204 is mounted on the upper end of the first movable member 203. The first stabilizing rod 202 and the fixed frame 201 are movably connected, and the first movable member 203 is slidably mounted on the surface of the first stabilizing rod 202. The first movable member 203 and the first positioning ring 204 are fixedly connected. The second positioning assembly 3 includes a second stabilizing rod 301, a telescopic frame 302, a second movable member 303, and a second positioning ring 304. 4. Telescopic frames 302 are movably mounted on both the left and right ends of the second stabilizer bar 301, and a second movable member 303 is mounted on the surface of the second stabilizer bar 301. A second positioning ring 304 is provided at the end of the second movable member 303 away from the second stabilizer bar 301. The second positioning ring 304 and the first positioning ring 204 have the same structure, and the second positioning ring 304 and the second movable member 303 are integrally formed. The second movable member 303 is slidably connected to the middle section surface of the second stabilizer bar 301, and one end of the telescopic frame 302 is horizontally mounted on the lower drive. One end of the movable bearing housing 104 can be adjusted horizontally by utilizing the structural mobility between the first movable member 203, the second movable member 303 and the first stabilizing rod 202 and the second stabilizing rod 301, or rotated at a certain angle with the first stabilizing rod 202 and the second stabilizing rod 301 as the center. This allows for appropriate structural adjustment of the first positioning ring 204 and the second positioning ring 304, so that each yarn passing through a set of first positioning rings 204 and second positioning rings 304 can maintain an effective distance between them.

[0026] like Figures 1 to 5As shown, the roller assembly 1 includes an upper roller 101, an upper drive bearing housing 102, a lower roller 103, a lower drive bearing housing 104, and a bidirectional lead screw 105. The upper roller 101 is connected to the upper drive bearing housing 102 at both its left and right ends, and the lower roller 103 is mounted directly below the upper roller 101. The lower roller 103 is also connected to the lower drive bearing housing 104 at both its left and right ends. Furthermore, both ends of the lower drive bearing housing 104 and the upper drive bearing housing 102 are... A bidirectional lead screw 105 is installed vertically. The lower roller 103 and the upper roller 101 have the same structure and are arranged in parallel with each other. Three sets of the upper roller 101 and lower roller 103 are equidistantly arranged along the sides of the upper drive bearing housing 102 and the lower drive bearing housing 104, respectively. The twisting assembly 5 includes a first servo motor 501, a rotary frame 502, a second servo motor 503, and a winding roller 504. The top power output end of the first servo motor 501 is mounted on a rotating frame 502 via a coupling, and a second servo motor 503 is horizontally mounted on one side of the rotating frame 502. The power output end of the second servo motor 503 is mounted on a winding roller 504 via a coupling, and a guide ring 505 is mounted directly above the winding roller 504. The guide ring 505 is fixedly connected to the rotating frame 502, and the winding roller 504 is horizontally mounted in the middle of the inner side of the rotating frame 502. With the structure of the bidirectional screw 105, the upper drive bearing seat 102 and the lower drive bearing seat 104 are structurally connected to each other. When the bidirectional screw 105 is vertically screwed, the upper drive bearing seat 102 and the lower drive bearing seat 104 will simultaneously move up and down within a certain distance along the surface of the bidirectional screw 105 in the vertical direction, thereby driving the upper roller 101 and the lower roller 103 to move up and down in the vertical direction.

[0027] In summary, as Figures 1 to 5 As shown, in use, this yarn twisting and positioning structure firstly, according to the processing needs of the yarn and the number of yarn strands to be processed, install a corresponding number of first movable parts 203 and second movable parts 303 connected to the first positioning ring 204 and the second positioning ring 304 on the surfaces of the first stabilizing rod 202 and the second stabilizing rod 301, respectively. Then, move and rotate the first movable parts 203 and the second movable parts 303 along the surfaces of the first stabilizing rod 202 and the second stabilizing rod 301 to adjust them to an appropriate spacing and angle to ensure the positioning guidance of the subsequent yarn.

[0028] Then, by using the horizontal extension and retraction of the telescopic frame 302, the distance between the second positioning component 3 and the twisting component 5 below is adjusted to an appropriate position. Then, the bidirectional lead screw 105 is rotated in the vertical direction to drive and adjust the upper drive bearing seat 102 and the lower drive bearing seat 104 connected thereto, thereby adjusting the vertical distance between the upper roller 101 and the lower roller 103 and keeping it within the range that is suitable for the diameter of the yarn being processed.

[0029] Then, the yarns to be processed are passed through the first positioning ring 204 and the second positioning ring 304 one by one, so that each yarn is independently spaced. After the yarns pass through the entire first positioning assembly 2, roller assembly 1 and second positioning assembly 3 in sequence, the multiple yarns are gathered above the top guide ring 505 of the rotary frame 502 and passed through it, and finally fixed to the surface of the winding roller 504.

[0030] Then, the twisting component 5 will work in conjunction with the upstream feeding equipment. Under the operation of the first servo motor 501, the rotary frame 502 connected to its power output end will rotate axially in the vertical direction to twist the multi-strand yarn. At the same time, the second servo motor 503 on one side of the rotary frame 502 will operate synchronously and drive the winding roller 504 connected to its power output end to rotate axially in the horizontal direction to synchronously wind up the twisted yarn. Under the rolling and pressing of the roller component 1 and the operation of the twisting component 5, the multi-strand yarn will be gradually twisted and wound up for subsequent processing.

[0031] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
