Description

Technical Field

[0001] This invention relates to the field of polyester staple fiber processing, and particularly to a false twisting device for polyester staple fibers and its method of use. Background Technology

[0002] Polyester staple fiber is a type of chemical fiber. In order to increase the elasticity of the fiber during processing, polyester staple fiber usually needs to be false twisted, so a false twisting machine is required.

[0003] Existing false twisting machines, when processing short fibers, encounter fiber lint on the polyester short fibers. This lint falls into the machine during processing, easily causing internal contamination and increasing the probability of damage. It also increases the difficulty of cleaning the lint, requiring the machine to be stopped, thus reducing the efficiency of polyester short fiber false twisting. Therefore, to solve these problems, a false twisting device for polyester short fibers and its usage method are proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a false twisting device for polyester staple fibers and a method for using it, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a false twisting device for polyester staple fibers, comprising a worktable and a false twisting machine body fixedly disposed at the top of the worktable, wherein a winding structure is symmetrically disposed at the top of the worktable, and a cleaning structure is disposed outside the winding structure, the cleaning structure comprising:

[0006] The mounting shell is movably disposed on the front side of the winding structure. The end face of the mounting shell opposite to the winding structure is provided with a through groove.

[0008] The mounting assembly is fixedly disposed at the end of the mounting shell and the cleaning roller, and the mounting assembly is used to limit the position of the cleaning roller in the inner cavity of the mounting shell.

[0009] Preferably, the mounting assembly includes a movable rod and a third spring. The third spring is fixedly sleeved on the outer wall of the movable rod and fixedly disposed on the inner wall of the mounting housing. The movable rod is movably inserted into the end of the cleaning roller.

[0010] Preferably, the winding structure includes:

[0011] A winding rod, used for winding and unwinding polyester staple fibers;

[0012] Two limiting plates are respectively movably interposed at both ends of the winding rod; both limiting plates are used to limit the winding and unwinding range of polyester staple fibers on the winding rod;

[0013] Two support rods are fixedly installed on opposite end faces of two limiting plates, and the support rods are used to support the position of the limiting plates.

[0014] Preferably, the winding structure further includes two movable blocks, a movable groove, and a drive rod. The movable groove is located at the top of the worktable, the drive rod is movably disposed within the inner cavity of the movable groove, and both movable blocks are sleeved on the outer wall of the drive rod.

[0015] Preferably, a fixing structure for limiting the winding rod is provided between the winding rod and the limiting plate, the fixing structure including:

[0016] A fixing rod is movably interlocked with the side of the limiting plate and the support rod, and an extrusion groove is provided on the front of the fixing rod;

[0017] A fixing groove is provided at the end of the winding rod;

[0018] The first extrusion rod is movably disposed within the inner cavity of the limiting plate and located on the front side of the fixed rod.

[0019] Preferably, the fixing structure further includes a support ring, a mounting ring, a second compression rod, and a limiting component. The support ring is movably sleeved on the outer wall of the mounting ring, and a plurality of first springs are fixedly arranged between the support ring and the mounting ring. The second compression rod is movably arranged on one side of the support ring through the limiting component.

[0020] Preferably, the limiting component includes a sleeve and a second spring, the second spring being fixedly disposed in the inner cavity of the sleeve, and the sleeve being fixedly disposed in the inner cavity of the movable groove.

[0021] Preferably, the support assembly includes a connecting cylinder and a rod, the rod being movably interlocked with the outer wall of the connecting cylinder, the bottom end of the rod being fixedly disposed with the top end of the workbench, and the connecting cylinder having a hollow structure.

[0022] Preferably, a connecting structure is provided between the connecting cylinder and the limiting plate, the connecting structure including:

[0023] A connecting rod is fixedly mounted on the outer wall of the limiting plate, and an insert rod is fixedly mounted on the outer wall of the connecting rod.

[0024] A spiral groove is formed on the inner wall of the connecting cylinder, and the inserting rod is movably inserted into the inner cavity of the spiral groove.

[0025] This invention also provides a method for using a false twisting device for polyester staple fibers, including the following specific steps:

[0026] Step 1: Wrap the polyester staple fiber to be false twisted onto the winding rod. Then place the winding rod between the two limiting plates. By starting the drive rod, the drive rod rotates and drives the movable blocks to move relative to each other. The movable blocks are fixed to the two support rods respectively. Therefore, the movement of the support rods can drive the limiting plates to move in opposite directions, so that they can move and interlock with the two ends of the winding rod. Stop the rotation of the drive rod so that the winding rod is on one side of the false twisting machine body. After passing through the false twisting machine body, one end of the polyester staple fiber wound on the winding rod is wound and fixed to the winding rod on the other side of the false twisting machine body.

[0027] Step 2: As the limiting plate moves relative to the connecting rod, the connecting rod will move synchronously. When the connecting rod moves to the position of the connecting cylinder, as the connecting rod continues to move, the inserting rod will move and intersect with the inner cavity of the spiral groove, and will move along the inner cavity of the spiral groove. However, the position of the inserting rod is relatively limited and can only move laterally. Therefore, the spiral groove will rotate under the insertion connection of the inserting rod, which will cause the connecting cylinder to rotate counterclockwise. As a result, the cleaning roller will rotate to the front of the winding rod. When the polyester short fibers on the winding rod are unwound, due to the friction with the cleaning roller, the lint on the short fibers will adhere to the outer wall of the cleaning roller, avoiding lint contamination of the false twisting machine body.

[0028] Step 3: When the polyester staple fibers on the outer wall of the winding rod are false-twisted in segments, the position of the winding rod can be restricted during the initial limiting twisting to prevent the winding rod from rotating and affecting the twisting effect. By continuing to rotate the drive rod, the movable block continues to move relative to the second extrusion rod. As the movable block continues to move, it will squeeze the second extrusion rod, causing the second extrusion rod to move towards the outer wall of the support ring and squeeze the outer wall of the support ring. This causes the support ring to move towards the end face away from the second extrusion rod. At the same time, it drives the first extrusion rod to move towards the extrusion groove. As the first extrusion rod and the extrusion groove intersect, a lateral driving force is generated on the fixed rod, so that the fixed rod intersects and squeezes the inner cavity of the fixed groove, thereby restricting the position of the winding rod.

[0029] The technical effects and advantages of this invention are as follows:

[0030] (1) The present invention utilizes a combination of winding structure and cleaning structure to enable polyester staple fiber to be wound and unwound on the winding structure, thereby avoiding the loading and unloading of short fiber false twisting process segment by segment, effectively improving the effect of short fiber false twisting. Furthermore, when the short fiber is unwound through the false twisting machine body, the cleaning structure can remove the lint on the short fiber, thereby preventing lint from entering the false twisting machine body and causing pollution, reducing the difficulty of lint cleaning, and effectively improving the effect and quality of short fiber processing.

[0031] (2) The present invention utilizes a combination of fixed structure and winding structure to enable the winding rod to be rotatable or fixed as needed, thereby adapting to the segmented false twisting of short fibers. It can be in a fixed state during the segmented false twisting process, thus maintaining the false twisting operation. After the segmented false twisting is completed, the winding rod can be rotated to perform false twisting of the next fiber, thus making the winding rod more flexible and improving the efficiency of polyester short fiber false twisting.

[0032] (3) The present invention utilizes the connection structure to enable the cleaning structure to adjust its orientation as the limiting plate restricts the position of the winding rod, so as to quickly position it on the front of the winding rod, which provides convenience for the use of the cleaning roller and enhances the cleaning efficiency of the cleaning roller for polyester short fibers.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] This invention provides, for example Figure 1-7 The illustrated false twisting device for polyester staple fibers includes a worktable 1 and a false twisting machine body 2 fixedly mounted on the top of the worktable 1. An external winding mechanism is used in conjunction with the worktable 1. The winding mechanism is a commonly used existing structure, which drives a winding rod to wind the staple fibers, allowing them to be wound onto the winding rod for processing by the false twisting machine body 2. (Further details will not be provided.) The top of the worktable 1 is symmetrically equipped with winding structures 3. A cleaning structure 5 is provided outside the winding structures 3. The cleaning structure 5 includes a mounting shell 501, a cleaning roller 502, and mounting components. The mounting shell 501 is movably mounted on the front of the winding structures 3, and the mounting shell 501 faces away from the front. The end face of the winding structure 3 is provided with a through groove. The front of the mounting shell 501 is symmetrically provided with support components for limiting the position of the mounting shell 501. The support components include a connecting cylinder 503 and a rod 504. The rod 504 is movably inserted into the outer wall of the connecting cylinder 503. The bottom end of the rod 504 is fixedly set to the top end of the worktable 1. The connecting cylinder 503 is a hollow structure. The cleaning roller 502 is movably set in the inner cavity of the mounting shell 501. The cleaning roller 502 is used to clean the polyester short fibers on the winding structure 3. The mounting components are fixedly set at the ends of the mounting shell 501 and the cleaning roller 502. The mounting components are used to limit the position of the cleaning roller 502 in the inner cavity of the mounting shell 501.

[0043] like Figure 1 and Figure 2As shown, the mounting shell 501 and the connecting cylinder 503 are fixedly installed. With the rod body 504 fixed to the worktable 1 and the rod body 504 being movably interlocked with the connecting cylinder 503, the mounting shell 501 can be indirectly installed above the worktable 1. The through groove on the front of the mounting shell 501 facilitates real-time observation of the adhesion of the cleaning roller 502, thereby preventing the cleaning roller 502 from continuing to be used after excessive lint has adhered to it. This effectively improves the cleaning effect of the cleaning roller 502. The cleaning roller 502 can squeeze and contact the polyester short fibers on the winding rod 301. As the winding rod 301 rotates, it can cause the cleaning roller 502 to adhere and clean the lint on the fibers, preventing the lint from entering the false twisting machine body 2 with the fibers and causing internal contamination of the false twisting machine. It also provides convenience and efficiency for cleaning the lint generated during fiber processing.

[0044] The mounting assembly includes a movable rod 505 and a third spring 506. The third spring 506 is fixedly sleeved on the outer wall of the movable rod 505 and fixedly disposed on the inner wall of the mounting housing 501. The movable rod 505 is movably inserted into the end of the cleaning roller 502.

[0045] like Figure 4 As shown, one end of the movable rod 505 passes through the outer wall of the mounting shell 501 and is movably inserted into the end of the cleaning roller 502. The other end of the movable rod 505 is round, which is convenient for the operator to pull. The third spring 506 allows the movable rod 505 to return to its original position after being pulled out of the end of the cleaning roller 502 by external force and the external force is released. This provides a connection between the cleaning roller 502 and the mounting shell 501, and also facilitates the disassembly and assembly of the cleaning roller 502 and the mounting shell 501. This allows the cleaning roller 502 to be quickly and individually removed for cleaning, and provides effective support for the reuse of the cleaning roller 502.

[0046] The winding structure 3 includes a winding rod 301, two limiting plates 302, and two support rods 303. The winding rod 301 is used for winding and unwinding polyester staple fibers. The two limiting plates 302 are respectively movably inserted at both ends of the winding rod 301. Both limiting plates 302 are used to limit the winding and unwinding range of polyester staple fibers on the winding rod 301. The two support rods 303 are respectively fixedly installed on the opposite end faces of the two limiting plates 302. The support rods 303 are used to support the position of the limiting plates 302.

[0047] like Figure 1 and Figure 2As shown, the winding rod 301 is positioned by interlocking with the limiting plate 302. The winding rod 301 winds the polyester staple fiber, allowing the polyester staple fiber to be continuously false-twisted in segments during the false-twisting process. This avoids the need for multiple loading and unloading operations of the polyester staple fiber, facilitating the false-twisting process and effectively improving the efficiency of the false-twisting. The limiting plate 302 has a convex cross-section, which facilitates the movable interlocking connection with the end of the winding rod 301. Furthermore, the shape of the limiting plate 302 can limit the usage of the winding rod 301 by varying the interlocking range with it, effectively improving the flexibility of the winding rod 301. The support rod 303 provides effective support for the limiting plate 302 by being fixedly set with it.

[0048] The winding structure 3 also includes two movable blocks 304, a movable groove 305, and a drive rod 306. The movable groove 305 is opened at the top of the worktable 1, and the drive rod 306 is movably disposed in the inner cavity of the movable groove 305. Both movable blocks 304 are sleeved on the outer wall of the drive rod 306.

[0049] like Figure 1 and Figure 6 As shown, two movable blocks 304 are fixedly installed at the bottom ends of two support rods 303 respectively. Both movable blocks 304 are threadedly connected to drive rods 306. Drive rods 306 can be either double-acting screws or double-acting lead screws. One end of drive rod 306 is equipped with a drive component, which can be either a drive motor or a manual throttle. The manual or electric drive method can be selected according to actual usage requirements. By rotating drive rod 306, movable blocks 304 can be moved synchronously, thereby enabling support rods 303 to move the position of limit plate 302. This improves the convenience of adjusting the position of limit plate 302 and enhances the flexibility and efficiency of assembling and disassembling the winding rod 301.

[0050] A fixing structure 4 for limiting the winding rod 301 is provided between the winding rod 301 and the limiting plate 302. The fixing structure 4 includes a fixing rod 401, a fixing groove 402 and a first pressing rod 404. The fixing rod 401 is movably inserted into the side of the limiting plate 302 and the support rod 303. The front of the fixing rod 401 is provided with a pressing groove 403. The fixing groove 402 is opened at the end of the winding rod 301. The first pressing rod 404 is movably disposed in the inner cavity of the limiting plate 302 and is located on the front of the fixing rod 401.

[0051] like Figure 5As shown, one end of the fixing rod 401 passes through one side of the limiting plate 302, and the other end of the fixing rod 401 passes through the end face of the support rod 303 away from the limiting plate 302 and extends to the outside. A spring is fixedly sleeved on the outer wall of the fixing rod 401, and the spring is fixedly set with the inner wall of the support rod 303. The fixing rod 401 moves along with the limiting plate 302. The front of the fixing rod 401 has an extrusion groove 403, one side of the inner cavity of the extrusion groove 403 is arc-shaped, the end of the first extrusion rod 404 facing the extrusion groove 403 is arc-shaped, and the first extrusion rod 404 is an inverted L-shape. The bottom end of the first extrusion rod 404 is connected to the movable The top of block 304 is fixedly installed. When the winding rod 301 is in a rotatable state, the fixing rod 401 is separated from the fixing groove 402. When it is necessary to position the winding rod 301, the first extrusion rod 404 can be moved toward the extrusion groove 403, so that the first extrusion rod 404 can be inserted into the inner cavity of the extrusion groove 403. At the same time, the arc-shaped setting of the opposite end of the first extrusion rod 404 and the extrusion groove 403 can make the fixing rod 401 move toward the fixing groove 402. Thus, while the fixing rod 401 is inserted into the fixing groove 402, the position of the winding rod 301 can be restricted.

[0052] The fixing structure 4 also includes a support ring 405, a mounting ring 406, a second pressing rod 408, and a limiting component. The support ring 405 is movably sleeved on the outer wall of the mounting ring 406. A plurality of first springs 407 are fixedly arranged between the support ring 405 and the mounting ring 406. The second pressing rod 408 is movably arranged on one side of the support ring 405 through the limiting component.

[0053] like Figure 6 As shown, the support ring 405 is movably sleeved on the outer wall of the mounting ring 406 via the first spring 407. The mounting ring 406 is made of either elastic rubber or elastic silicone. The mounting ring 406 is stably sleeved on the outer wall of the drive rod 306. Due to the fixed setting of the support ring 405 and the first extrusion rod 404, the position of the support ring 405 can drive the position of the first extrusion rod 404 to move simultaneously. The end of the second extrusion rod 408 facing the support ring 405 is arc-shaped. The second extrusion rod 408 is pushed by the movable block 304, thereby moving towards the support ring 405. With the arc-shaped end of the second extrusion rod 408 and the arc-shaped outer wall of the support ring 405, the support ring 405 will move vertically towards the second extrusion rod 408 under the extrusion of the second extrusion rod 408, thereby driving the first extrusion rod 404 to move towards the extrusion groove 403. This ensures the effectiveness of the insertion of the fixed rod 401 and the fixed groove 402, thereby strengthening the stability of the position restriction of the winding rod 301.

[0054] The limiting component includes a sleeve 409 and a second spring 410, the second spring 410 being fixedly disposed in the inner cavity of the sleeve 409, and the sleeve 409 being fixedly disposed in the inner cavity of the movable groove 305.

[0055] like Figure 7 As described above, the sleeve 409 is fixedly disposed in the inner cavity of the movable groove 305 and located between the support ring 405 and the movable block 304, providing positional support for the second extrusion rod 408. The second spring 410 is fixedly sleeved on the outer wall of the second extrusion rod 408, and the arrangement of the second spring 410 provides elastic support for the repositioning of the second extrusion rod 408.

[0056] A connecting structure 6 is provided between the connecting cylinder 503 and the limiting plate 302. The connecting structure 6 includes a connecting rod 601 and a spiral groove 603. The connecting rod 601 is fixedly installed on the outer wall of the limiting plate 302. An inserting rod 602 is fixedly installed on the outer wall of the connecting rod 601. The spiral groove 603 is opened on the inner wall of the connecting cylinder 503. The inserting rod 602 and the inner cavity of the spiral groove 603 are movably interlocked.

[0057] like Figure 2 As shown, the connecting rod 601 is L-shaped and fixedly mounted to the outer wall of the limiting plate 302. The connecting rod 601 moves with the movement of the limiting plate 302. The inserting rod 602 is fixedly mounted to the outer wall of the connecting rod 601 and will also move with the movement of the connecting rod 601. When the inserting rod 602 moves to the position of the spiral groove 603, as the connecting rod 601 continues to move, the inserting rod 602 will be inserted into the spiral groove 603. As the inserting rod 602 continues to move, it will cause the spiral groove 603 to rotate, thereby rotating the cleaning roller 502 toward the winding rod 301. This effectively improves the flexibility of the cleaning roller 502's position movement, allowing the position of the cleaning roller 502 to be adjusted while the winding rod 301 is installed, effectively improving the cleaning effectiveness of polyester staple fibers.

[0058] How to use this invention:

[0059] Step 1: Wrap the polyester staple fiber to be false twisted onto the winding rod 301. Then place the winding rod 301 between the two limiting plates 302. By starting the drive rod 306, the drive rod 306 rotates and drives the movable block 304 to move relative to each other. The movable block 304 is fixedly set with the two support rods 303 respectively. Therefore, the movement of the support rods 303 can drive the limiting plates 302 to move in opposite directions, so that they can move and interlock with the two ends of the winding rod 301. Stop the rotation of the drive rod 306 so that the winding rod 301 is on one side of the false twisting machine body 2. After passing through the false twisting machine body 2, one end of the polyester staple fiber wound on the winding rod 301 is wound and fixed with the winding rod 301 on the other side of the false twisting machine body 2.

[0060] Step 2: As the limiting plate 302 moves relative to the connecting rod 601, the connecting rod 601 will move synchronously. When the connecting rod 601 moves to the position of the connecting cylinder 503, as the connecting rod 601 continues to move, the inserting rod 602 will move through the inner cavity of the spiral groove 603 and move along the inner cavity of the spiral groove 603. However, the position of the inserting rod 602 is relatively limited and can only move laterally. Therefore, the spiral groove 603 will rotate under the insertion of the inserting rod 602, which will cause the connecting cylinder 503 to rotate counterclockwise. As a result, the cleaning roller 502 will rotate to the front of the winding rod 301. When the polyester short fibers on the winding rod 301 are unwound, due to the friction with the cleaning roller 502, the lint on the short fibers will adhere to the outer wall of the cleaning roller 502, thus avoiding lint contamination of the false twisting machine body 2.

[0061] Step 3: When the polyester short fibers on the outer wall of the winding rod 301 are false-twisted in segments, the position of the winding rod 301 can be restricted during the initial twisting to prevent the winding rod 301 from rotating and affecting the twisting effect. By continuing to rotate the drive rod 306, the movable block 304 continues to move relative to the second extrusion rod 408. As the movable block 304 continues to move, it will squeeze the second extrusion rod 408, causing the second extrusion rod 408 to move towards the outer wall of the support ring 405 and squeeze the outer wall of the support ring 405, causing the support ring 405 to move towards the end face away from the second extrusion rod 408. At the same time, it drives the first extrusion rod 404 to move towards the extrusion groove 403. As the first extrusion rod 404 and the extrusion groove 403 intersect, a lateral driving force is generated on the fixed rod 401, so that the fixed rod 401 intersects and squeezes the inner cavity of the fixed groove 402, thereby restricting the position of the winding rod 301.
