Description

Technical Field

[0001] This utility model relates to the field of winding replacement technology, specifically a quick winding replacement component for a knitting fabric winding machine. Background Technology

[0002] In the knitting industry's production process, the winding machine plays an indispensable role as a key piece of equipment for forming yarn. Its core responsibility is to transform the bobbins produced by the spinning department into packages that meet the requirements of subsequent weaving processes. The performance of the winding machine directly affects the production efficiency of subsequent knitting processes and the quality of the final product. With the increasing diversification of market demand for knitted fabrics, flexible fabrics are widely favored due to their unique texture and applicability. This places higher demands on the winding process, requiring it to be compatible with various elastic yarns, such as spandex blends, and also to meet the needs of variable package sizes to address the production requirements of different flexible fabrics. Against this backdrop, rapid winding changeover has become one of the core elements for improving the overall rhythm of the knitting production line and ensuring production continuity and efficiency.

[0003] However, existing winding replacement technologies have significant drawbacks and are ill-suited to the high-efficiency production demands of modern knitting industries. Traditional winding machine replacement procedures are cumbersome, relying excessively on manual multi-step operations, including disassembling fixing bolts and adjusting tension mechanisms. These operations are not only time-consuming and labor-intensive, significantly increasing the time cost of the replacement process and reducing production efficiency, but also prone to problems such as unstable yarn tension and inconsistent package formation due to improper operation or errors during manual processing, thus affecting the product quality of subsequent weaving processes. Utility Model Content

[0004] The purpose of this invention is to provide a quick-change component for a knitting fabric winding machine. The winding body is placed directly onto a receiving tray, and the receiving tray has a positioning post in the center that can be inserted into the center of the winding body. The winding body can be quickly separated from the winding body by moving the moving block, thus solving the problem of long replacement time in traditional devices.

[0005] To address the problems of existing technologies, this utility model provides a quick-change component for a knitting fabric winding machine, comprising: a support plate, which can be installed on the knitting fabric winding machine to store the winding body; a limiting sleeve, which is disposed on the support plate and is evenly distributed thereon; and a winding fixing component, which has multiple sets and is respectively installed in each limiting sleeve to fix the winding body, wherein the winding body has a through hole at its center; the winding fixing component includes a receiving plate that can rotate within the limiting sleeve, and a positioning post that can be inserted into the through hole in the winding body is also provided at the center of the top of the receiving plate; the receiving plate is also evenly provided with a plurality of sliding grooves; and the winding fixing component further includes a movable locking block that can be slidably disposed in the sliding grooves and can fix the winding body on the top of the receiving plate.

[0006] Preferably, the clamping part of the movable card block is L-shaped and is used to press against the edge of the winding cylinder body.

[0007] Preferably, the winding fixing assembly further includes a rotating column vertically connected to the center of the bottom of the receiving plate, and the rotating column extends downward and passes through the bottom of the support plate, and an end cap is fixed to the bottom of the rotating column.

[0008] Preferably, a movable sleeve is also fitted around the rotating column, and the movable sleeve can move up and down the rotating column. The movable sleeve is also provided with connecting blocks that correspond one-to-one with the movable locking blocks. A connecting rod is hinged to the connecting block via a shaft, and one end of the connecting rod is hinged to the bottom end of the movable locking block.

[0009] Preferably, a limiting groove is vertically formed around the rotating column, and the movable sleeve slides into the limiting groove and extends into the interior of the rotating column. A movable rod is also provided at the center of the bottom of the movable sleeve, and the movable rod extends to the bottom of the rotating column.

[0010] Preferably, a spring is also fitted on the upper part of the rotating column, with the bottom end of the spring connected to the movable sleeve and the top end of the spring connected to the bottom of the receiving plate.

[0011] Preferably, the winding fixing assembly further includes a limiting cover fixed to the bottom end of the support plate, and a bearing is embedded inside the limiting cover, and the inner ring of the bearing cooperates with the rotating column.

[0012] Preferably, the winding cylinder fixing assembly further includes a pulley fitted around the bottom of the rotating column for driving the rotating column to rotate.

[0013] The advantages of this utility model compared to the prior art are as follows: This application achieves a quick-fixing structural foundation for the winding body by setting a receiving plate inside the limiting sleeve and opening a sliding groove on the receiving plate, with a movable locking block slidably arranged in the sliding groove. The movable locking block is hinged to the connecting block on the movable sleeve through a connecting rod, forming a linkage transmission mechanism, providing a mechanical transmission path for the winding body replacement operation. When it is necessary to replace the winding body, simply push the moving rod upward, and the moving rod transmits the driving force to the movable sleeve, causing the movable sleeve to move upward axially. During this process, the movable sleeve drives the connecting rod to deflect at an angle through the connecting block, thereby driving the movable locking block to slide along the sliding groove away from the winding body, so that the movable locking block is completely separated from the winding body, thereby quickly releasing the fixing constraint on the winding body and realizing convenient disassembly and replacement of the winding body.

[0014] Furthermore, by installing a spring between the receiving plate and the movable sleeve, and utilizing the spring's elastic reset characteristic, after the winding body is replaced, the external force on the movable rod is removed. The spring will push the movable sleeve to move axially downwards, and through the reverse transmission of the connecting rod, it will drive the movable locking block to reset along the slide groove, so that the movable locking block automatically clamps the winding body, completing the rapid fixing of the winding body. This structural design not only simplifies the winding replacement operation steps and reduces the complexity of manual intervention, but also ensures the consistency and stability of the winding body installation through the automatic mechanical reset mechanism, effectively improving the winding replacement efficiency and installation reliability.

[0022] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0023] Reference Figures 1-6 As shown, this utility model provides a quick-change component for a knitting fabric winding machine, comprising: a support plate 1, which can be installed on the knitting fabric winding machine to store the winding body 3; a limiting sleeve 11, which is set on the support plate 1 and is evenly distributed on the support plate 1; a winding fixing component 2, which has multiple sets and is respectively installed in each limiting sleeve 11 to fix the winding body 3, the winding body 3 having a through hole in the center; the winding fixing component 2 includes a receiving plate 21 that can rotate in the limiting sleeve 11, the receiving plate 21 can rotate freely in the limiting sleeve 11, thereby causing the winding body 3 to rotate, thereby causing the yarn to wind on the winding body 3, the center position of the top of the receiving plate 21 is also provided with a positioning post 212 that can be inserted into the through hole in the winding body 3, the receiving plate 21 is also evenly provided with a plurality of sliding grooves 211, the winding fixing component 2 also includes a movable locking block 22 that can be slidably set in the sliding grooves 211 and can fix the winding body 3 on the top of the receiving plate 21. The grooves 211 are evenly opened along the radial direction of the receiving plate 21 (usually 3-4 grooves) to provide a precise sliding track for the moving block 22, ensuring that the moving block 22 can only move in the direction "closer to or away from the center", so as to adapt to winding cylinders of different diameters. The clamping part of the moving block 22 is L-shaped to press against the edge of the winding cylinder body 3.

[0024] The support plate 1 is fixed on the winding machine, and the receiving plate 21 is embedded into the limiting sleeve 11 to ensure that the receiving plate 21 can rotate flexibly. The operator aligns the through hole of the winding body 3 with the positioning post 212 of the receiving plate 21, inserts it to complete the center positioning, and slides the moving block 22 along the slide groove 211 so that the horizontal section of the "L" shaped clamping part presses against the top edge of the winding body 3 and the vertical section fits against the outer wall of the winding body 3, thereby fixing the winding body 3.

[0025] The winding fixing assembly 2 also includes a rotating column 25 vertically connected to the center of the bottom of the receiving plate 21, and the rotating column 25 extends downward and passes through the bottom of the support plate 1, and an end cap 252 is fixed to the bottom of the rotating column 25. A movable sleeve 24 is also sleeved on the outside of the rotating column 25, and the movable sleeve 24 can move up and down on the rotating column 25. A connecting block 241 corresponding to the movable locking block 22 is also provided on the outside of the movable sleeve 24. A connecting rod 23 is hinged to the connecting block 241 through a shaft, and one end of the connecting rod 23 is hinged to the bottom end of the movable locking block 22.

[0026] The moving sleeve 24 moves upward, causing the connecting block 241 to rise synchronously. The bottom end of the connecting rod 23 rises with the connecting block 241, and the top end pushes the moving block 22 to slide away from the center along the slide groove 211 through the hinge shaft. The "L"-shaped clamping part of the moving block 22 gradually moves away from the winding body 3, and the moving block 22 releases the winding body 3.

[0027] A limiting groove 251 is vertically formed around the rotating column 25, and the movable sleeve 24 slides in engagement with the limiting groove 251 and extends into the interior of the rotating column 25. A movable rod 29 is also provided at the center of the bottom of the movable sleeve 24, extending into the bottom of the rotating column 25. The limiting groove 251 is vertically formed along the axial direction of the rotating column 25, and the portion of the movable sleeve 24 extending into the interior of the rotating column 25 slides in engagement with the limiting groove 251. When the rotating column 25 drives the receiving plate 21 and the winding cylinder body 3 to rotate, the movable sleeve 24 will rotate synchronously with the rotating column 25.

[0028] A spring 26 is also fitted on the upper part of the rotating column 25. The bottom end of the spring 26 is connected to the movable sleeve 24, and the top end of the spring 26 is connected to the bottom of the receiving plate 21.

[0029] Spring 26 releases its elastic potential energy, pushing the movable sleeve 24 to return to its original position. During this process, the movable sleeve 24 drives the movable locking block 22 to automatically retract towards the center via the connecting rod 23, thereby automatically clamping the winding cylinder body 3.

[0030] The winding fixing assembly 2 also includes a limiting cover 27 fixed to the bottom end of the support plate 1, and a bearing 271 is embedded inside the limiting cover 27, and the inner ring of the bearing 271 cooperates with the rotating column 25. The winding fixing assembly 2 also includes a pulley 28 fitted on the bottom of the rotating column 25 for driving the rotating column 25 to rotate.

[0031] The pulley 28 is fixed to the rotating column 25 by a key connection or expansion sleeve. It can be connected to the drive motor (such as a servo motor) of the winding machine by a synchronous belt or V-belt to transmit the rotational power of the motor to the rotating column 25, thereby driving the receiving plate 21 and the winding body 3 to rotate, so that the yarn is wound on the winding body 3.

[0032] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
