Description

Technical Field

[0001] This application relates to the field of industrial yarn production technology, and in particular to a production process for colored polyester industrial yarn. Background Technology

[0002] Polyester industrial yarn refers to high-strength, coarse-denier polyester filaments used in industry. Based on their properties, they can be classified into high-strength, low-elongation (standard type), high-modulus, low-shrinkage, high-strength, low-shrinkage, and reactive types. Polyester industrial yarn possesses excellent properties such as high breaking strength, high elastic modulus, low elongation, and good impact resistance.

[0003] In the production process of polyester industrial yarn, polyester chips and masterbatch are usually fed together to a large screw for melt blending. Then, after being calculated by a metering pump, the yarn is ejected from the spinneret. After cooling, it is oiled, stretched, and finally wound into shape by a winding machine to obtain the desired colored polyester industrial yarn.

[0004] Currently, during the winding process, because the industrial filament is tightly wound on the take-up roller of the winding machine, the friction between the industrial filament and the take-up roller is relatively large, making it quite difficult to remove the industrial filament directly. Summary of the Invention

[0005] To facilitate the removal of industrial yarn from the winding machine, this application provides a production process for colored polyester industrial yarn.

[0006] The production process for colored polyester industrial yarn provided in this application adopts the following technical solution:

[0007] A production process for colored polyester industrial yarn includes the following steps:

[0008] S1: Melt blending, where polyester chips and masterbatch are fed to a large screw for melt blending;

[0009] S2: Extrusion, the mixed melt is extruded through a metering pump, filtered, and then ejected from a spinneret;

[0010] S3, cooled into filaments, solidified into filaments after being cooled by side blowing air;

[0011] S4, oiling, oiling industrial yarn bundles;

[0012] S5, stretching and shaping, using traction rollers to stretch and shape the filament bundle;

[0013] S6, winding, using a winding device to wind industrial filaments;

[0014] In step S6, the winding device includes a base plate, on which a winding disc is rotatably mounted. Multiple winding rods are mounted on the winding disc, all of which are circumferentially distributed on the winding disc and slide along the radial direction of the winding disc. A drive assembly is mounted on the base plate to drive all the winding rods to slide synchronously.

[0015] By adopting the above technical solution, the rotation of the winding disc allows the filament to be wound around all the winding rods. At this time, the winding rods keep the filament in a taut state. After winding is completed, the filament is cut off, and the drive assembly drives all the winding rods to slide. All the windings slide towards the center of the winding disc, which reduces the outer diameter of the circle formed by all the winding rods. This makes the filament loose on the winding rods, thereby greatly reducing the friction between the filament and the winding rods, making it easier for workers to remove the industrial filament.

[0016] Preferably, the winding reel has multiple sliding grooves, the number of which is the same as the number of winding rods and corresponds one-to-one. The length direction of the sliding grooves is distributed radially along the winding reel. The winding reel is slidably connected to a sliding block in the sliding groove, and the winding rod is mounted on the sliding block. The driving assembly includes a linkage reel, connecting rods, and a drive motor for rotating the linkage reel. The linkage reel is coaxially fixed to the output shaft of the drive motor. The linkage reel is hinged to multiple connecting rods, the number of which is the same as the number of sliding blocks and corresponds one-to-one. The end of the connecting rod away from the linkage reel is hinged to the corresponding sliding block. A compression spring is also provided in the sliding groove of the winding reel. The sliding block is located on the side away from the center of the winding disc. The length direction of the compression spring is consistent with the length direction of the sliding groove. One end of the compression spring is connected to the sliding block, and the other end of the compression spring is connected to the inner wall of the sliding groove. A drive disk is also coaxially fixed on the output shaft of the drive motor. An arc-shaped groove is formed on the drive disk, and the center of curvature of the arc-shaped groove is located at the center of the drive disk. A drive rod is eccentrically arranged on the winding disc. The drive rod extends into the arc-shaped groove and slides in cooperation with the arc-shaped groove. The drive motor drives the linkage disk to rotate. The linkage disk drives the sliding block to slide away from the center of the winding disc through the connecting rod. At the same time, the drive disk slides, and the drive rod slides to the other end of the arc-shaped groove.

[0017] By adopting the above technical solution, in the initial state, under the action of the compression spring, the sliding block will be located near the center of the winding disc. At this time, the circumference formed by all the winding rods is small. When the drive motor runs, it drives the linkage disc to rotate first. At this time, the winding disc does not rotate. When the linkage disc rotates, it drives the sliding block to slide away from the center of the winding disc through the connecting rod, so that the winding rods slide away from the center of the winding disc. Finally, the circumference formed by all the winding rods increases, and at the same time, the drive disc slides, and the drive rod slides along the arc groove and abuts against the other end of the arc groove. Then, the drive disc drives the winding disc to rotate through the drive rod, so as to realize the winding operation of the industrial filament. After the winding is completed, under the action of the compression spring, the sliding block will return to its original position. The sliding block drives the linkage disc to rotate through the connecting rod, and the linkage disc will rotate synchronously with the drive disc, so that the positions of the drive disc and the drive rod are reset. After the sliding block drives the winding rod to reset, the industrial filament is loosened on the winding rod, making it easy for the workers to take it out.

[0018] Preferably, a rotating sleeve is fixedly connected to the side of the winding disc near the linkage disc. The rotating sleeve is sleeved on the output shaft of the drive motor, and the rotating sleeve slides and rotates with the output shaft of the drive motor. A limiting member is provided on the base plate to restrict the rotation of the winding disc. The bottom wall of the arc-shaped groove is wedge-shaped. In the initial state, the end of the drive rod is located at the lower end of the arc-shaped groove. When the drive disc rotates, the drive rod slides along the lower end of the arc-shaped groove to the higher end. At this time, the winding disc slides away from the linkage disc on the output shaft of the drive motor and is released from the restriction of the limiting member. A reset assembly is also provided on the base plate, which causes the winding disc to slide and reset towards the linkage disc.

[0019] By adopting the above technical solution, the drive motor operates, the linkage disk rotates, and the linkage disk drives the winding rod to slide through the connecting rod. The rotation of the winding disk is restricted by the limiting component, which helps the linkage disk to stably drive the sliding block to slide when rotating, preventing the winding disk from rotating along with it and affecting the sliding block. At the same time, the drive disk rotates, and the drive rod slides along the arc groove from the lower end to the higher end. Because there is a certain displacement difference in the arc groove, the drive rod will be displaced in the horizontal direction, that is, it drives the winding disk to slide on the output shaft of the drive motor and slide away from the linkage disk. At this time, the limitation between the winding disk and the limiting component is released, and the winding disk can rotate with the drive disk through the drive rod. When the winding operation is completed, the drive motor stops. At this time, the reset component causes the winding disk to slide and form a restriction with the limiting component. When the reset component drives the winding disk to slide, the compression spring will also synchronously drive the sliding block to slide, so that the linkage disk and the drive disk can rotate and reset.

[0020] Preferably, the limiting member is an internal gear ring, which is fixedly installed on the base plate and located on the periphery of the winding disc. An external gear ring is fixedly connected to the outer periphery of the winding disc. The external gear ring and the internal gear ring are engaged and locked, and the external gear ring and the internal gear ring slide and cooperate in the horizontal direction.

[0021] By adopting the above technical solution, the rotation of the winding disc can be restricted by the meshing between the outer gear ring and the inner gear ring. However, since the outer gear ring and the inner gear ring can slide in the horizontal direction, when the drive rod slides along the arc groove, it causes the winding disc to slide, thus disengaging the outer gear ring and the inner gear ring and releasing the lock.

[0022] Preferably, an mounting plate is fixedly installed on the base plate, the mounting plate being located on the side of the winding reel away from the linkage reel. The mounting plate is provided with a sliding sleeve, and the sliding sleeve has an insertion groove. The reset assembly includes a sliding rod, an abutment wheel, and a first reset spring. The sliding rod is inserted into and slides in the insertion groove of the sliding sleeve. The sliding direction of the sliding rod is consistent with the sliding direction of the winding reel. The sliding sleeve forms a limiting port at the opening of the insertion groove. A limiting plate is formed on one end of the sliding rod inside the sliding sleeve. The abutment wheel is rotatably connected to the other end of the sliding rod, and the rotation axis of the abutment wheel is parallel to the rotation axis of the winding reel. The first reset spring is located inside the sliding sleeve, and the length direction of the first reset spring is consistent with the sliding direction of the sliding rod. One end of the first reset spring is connected to the bottom wall of the sliding sleeve, and the other end of the first reset spring is connected to the limiting plate. A rolling ring groove is provided on the side of the winding reel near the abutment wheel, and the abutment wheel rolls in engagement with the rolling ring groove.

[0023] By adopting the above technical solution, the abutting wheel is always located in the rolling ring groove, that is, a rotational engagement is formed between the abutting wheel and the winding disc. When the winding disc slides away from the linkage disc, it will drive the sliding rod to slide and compress the first return spring. When the subsequent winding disc rotates, the abutting wheel and the winding disc form a rolling engagement. After winding is completed, under the action of the first return spring, the sliding rod slides and pushes the winding disc towards the linkage disc through the abutting wheel. When the drive disc rotates, the drive rod is always in contact with the bottom wall of the abutting groove, ensuring that the end of the drive rod is reset to the lower end of the abutting groove, and that the outer gear ring and the inner gear ring mesh, thus locking the rotation of the winding disc.

[0024] Preferably, the winding disc has multiple mounting slots, the number of which is the same as the number of sliding slots and corresponds one-to-one. A limit rod is slidably installed in the mounting slot, a limit groove is opened on the side wall of the sliding block, and a limit component is provided on the winding disc to drive the limit rod to slide and engage with the limit groove.

[0025] By adopting the above technical solution, when the winding operation is being performed, the sliding block is located on the side away from the center, and the winding disc slides to the side away from the linkage disc. During the rotation of the winding disc, under the action of centrifugal force and inertia, the compression spring may float, causing the winding rod to be unable to tension the yarn bundle, thus affecting the winding effect of the yarn bundle. When the sliding block drives the winding rod box to the side away from the center, the position of the sliding block is limited by the insertion of the limiting rod into the upper limit groove of the sliding block, which helps to prevent the sliding block from sliding in the sliding groove and helps to ensure the winding effect of the yarn bundle.

[0026] Preferably, the limiting assembly includes a linkage gear, a first sprocket, a second sprocket, a chain, and a limiting gear. The linkage gear is rotatably connected to the side of the winding disc near the linkage disc, and the linkage gear is located at the edge of the winding disc. When the winding disc slides away from the winding disc, the linkage gear meshes with the internal gear ring. The first sprocket is located in the mounting groove and rotates coaxially with the linkage gear. The second sprocket is rotatably connected to the mounting groove. The chain is wound around the first sprocket and the second sprocket. The limiting gear rotates coaxially with the second sprocket. A limiting rack is slidably connected in the mounting groove. The limiting rod is fixedly connected to the limiting rack. The length direction of the limiting rack is perpendicular to the length direction of the limiting rod. A first helical tooth is formed on the limiting rack, and a second helical tooth is formed on the limiting gear. When the limiting gear rotates, the inclined surface of the second helical tooth abuts against the inclined surface of the first helical tooth, thereby driving the limiting rack to slide away from the limiting gear. A reset element is also provided in the winding disc to reset the limiting rack.

[0027] By adopting the above technical solution, when the winding disc slides away from the linkage disc, the linkage gear and the internal gear ring mesh. When the winding disc rotates, the linkage gear will travel on the internal gear ring, i.e., it will rotate. The linkage gear drives the first sprocket to rotate, and the first sprocket drives the second sprocket to rotate through the chain. The second sprocket drives the limiting gear to rotate. The rotation of the limiting gear abuts against the inclined surface of the second helical tooth and the inclined surface of the first helical tooth, thereby driving the limiting rack to slide a certain distance. The limiting rod slides accordingly and inserts into the limiting groove, realizing the limiting of the sliding block. When the winding operation is completed, the linkage gear stops rotating, and the reset component resets the limiting rack, so that the limiting rod is disengaged from the limiting groove. At this time, the sliding block can slide in the sliding groove under the action of the compression spring.

[0028] Preferably, the reset component is configured as a second reset spring, a connecting groove is provided in the winding disc, the mounting groove is connected to the sliding groove through the connecting groove, the limiting rod is inserted into the connecting groove and slides in cooperation, the second reset spring is sleeved on the periphery of the limiting rod, one end of the second reset spring is connected to the limiting rack, and the other end of the second reset spring is connected to the opening of the connecting groove.

[0029] By adopting the above technical solution, after the winding operation is completed, under the action of the second return spring, the limiting rack slides towards the limiting gear and meshes with the limiting gear, thus realizing that the limiting rod will disengage from the limiting groove.

[0030] Preferably, the limiting rod has a sliding groove, the length direction of which is perpendicular to the sliding direction of the limiting rod. The limiting rod slides within the sliding groove and engages with a limiting pin. A retaining spring is provided within the sliding groove on the limiting rod. One end of the retaining spring is connected to the bottom wall of the sliding groove, and the other end is connected to the limiting pin. A wedge-shaped surface is formed on the upper side of the limiting pin. The sliding block also has a pre-tightening groove on the side wall of the limiting groove that engages with the limiting pin.

[0031] By adopting the above technical solution, when the limiting rod is engaged with the limiting groove, and when the slide groove and the pre-tightening groove are connected, the limiting pin will engage with the pre-tightening groove under the action of the abutment spring, further locking the limiting rod and the sliding block; preventing the limiting rack from sliding towards the limiting gear during the interval of the second helical gear rotation during the rotation of the limiting gear, thus preventing the limiting rod from sliding back and forth. By utilizing the engagement of the limiting pin and the pre-tightening groove, the limiting rod will not easily slide, which helps to ensure that the limiting rod will not easily slide and reset during the rotation of the limiting gear; after the winding operation is completed, the limiting rod slides outward under the action of the second reset spring. At this time, under the action of the wedge surface, the limiting pin will slide into the slide groove until it disengages from the pre-tightening groove.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] 1. By utilizing the sliding of the winding rods, the outer diameter of the circumference formed by all the winding rods can be adjusted. When the outer diameter is large, the filament bundle can be wound. After winding, the outer diameter is reduced by the sliding of the winding rods, so that the filament bundle is in a relaxed state on the winding rods, making it easy for workers to remove the industrial filament.

[0034] 2. Under the action of the compression spring, the sliding block will be located near the center of the winding disc. At this time, the radius of the circle formed by all the winding rods is small. When the drive motor runs, it drives the linkage disc to rotate first. At this time, the winding disc does not rotate. When the linkage disc rotates, it drives the sliding block to slide away from the center of the winding disc through the connecting rod. This causes the winding rods to slide away from the center of the winding disc, ultimately increasing the radius of the circle formed by all the winding rods. At the same time, the drive disc slides, and the drive rod slides along the arc groove and abuts against the other end of the arc groove. Then, the drive disc drives the winding disc to rotate through the drive rod, thus realizing the winding operation of industrial filament. After the winding is completed, under the action of the compression spring, the sliding block will return to its original position. The sliding block drives the linkage disc to rotate through the connecting rod, and the linkage disc will rotate synchronously with the drive disc, so that the positions of the drive disc and the drive rod are reset.

[0035] 3. When the winding disc slides away from the linkage disc, the linkage gear and the internal gear ring mesh. When the winding disc rotates, the linkage gear will travel on the internal gear ring, thus rotating. The linkage gear drives the first sprocket to rotate, and the first sprocket drives the second sprocket to rotate through the chain. The second sprocket drives the limiting gear to rotate. The rotation of the limiting gear abuts against the inclined surface of the second helical tooth and the inclined surface of the first helical tooth, thereby causing the limiting rack to slide a certain distance. The limiting rod slides along with it and inserts into the limiting groove, thus limiting the sliding block. Attached Figure Description

Detailed Implementation

[0045] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0046] This application discloses a production process for colored polyester industrial yarn.

[0047] Reference Figure 1 The production process of colored polyester industrial yarn includes the following steps:

[0048] S1: Melt blending, where polyester chips and masterbatch are fed to a large screw for melt blending;

[0049] S2: Extrusion, the mixed melt is extruded through a metering pump, filtered, and then ejected from a spinneret;

[0050] S3, cooled into filaments, solidified into filaments after being cooled by side blowing air;

[0051] S4, oiling, oiling industrial yarn bundles;

[0052] S5, stretching and shaping, using traction rollers to stretch and shape the filament bundle;

[0053] S6, winding, using a winding device to wind industrial filaments.

[0054] In step S6, the winding device includes a base plate 1, a winding disk 2 is rotatably mounted on the base plate 1, and a plurality of winding rods 3 are mounted on the winding disk 2. In this application, three winding rods 3 are used as an example for explanation. The circumferential parts of the three winding rods 3 are on the winding disk 2, and the winding rods 3 are arranged to slide radially along the winding disk 2. A drive assembly 4 is provided on the base plate 1 to drive all the winding rods 3 to slide synchronously.

[0055] By rotating the winding disc 2, the industrial filament can be wound. After winding is completed, the drive assembly 4 drives all the winding rods 3 to slide. All the winding rods 3 slide in the circular direction of the winding disc 2, so that the filament bundle is relaxed on the winding rods 3, reducing the friction between the filament bundle and the winding rods 3, making it easy for workers to remove the industrial filament.

[0056] Multiple sliding grooves 21 are provided on the winding disc 2. The number of sliding grooves 21 is the same as the number of winding rods 3, and there are three of them. The three sliding grooves 21 correspond one-to-one with the three winding rods 3. The length direction of the sliding grooves 21 is distributed along the radial direction of the winding disc 2. The winding disc 2 is slidably connected to the sliding block 22 in the sliding groove 21. The sliding block 22 is in the shape of an I-beam. The winding rod 3 is fixedly connected to the corresponding sliding block 22.

[0057] Reference Figure 1 , Figure 2 and Figure 3 The drive assembly 4 includes a linkage disk 41, connecting rods 42, and a drive motor 43 that drives the linkage disk 41 to rotate. A support plate 11 is fixedly connected to the base plate 1. The drive motor 43 is fixedly mounted on the support plate 11. The rotation axis of the output shaft of the drive motor 43 is horizontal. The linkage disk 41 is coaxially fixed on the output shaft of the drive motor 43. A rotating sleeve 23 is integrally formed on the side of the winding disk 2 near the linkage disk 41. The rotating sleeve 23 is sleeved on the output shaft of the drive motor 43 and forms a rotational fit. Three connecting rods 42 are hinged on the linkage disk 41. The three connecting rods 42 correspond one-to-one with the three sliding blocks 22. A connecting rod 221 is fixedly connected to the sliding block 22. The end of the connecting rod 42 away from the linkage disk 41 is sleeved with the connecting rod 221, that is, the connecting rod 42 and the connecting rod 221 form a rotational engagement and a sliding engagement in the horizontal direction. A compression spring 211 is provided in the sliding groove 21 of the winding disk 2. The compression spring 211 is located on the side of the sliding block 22 away from the center of the winding disk 2. The length direction of the compression spring 211 is consistent with the length direction of the sliding groove 21. One end of the compression spring 211 is connected to the sliding block 22, and the other end of the compression spring 211 is connected to the inner wall of the sliding groove 21.

[0058] In the initial state, under the action of the compression spring 211, the sliding block 22 will drive the winding rod 3 to move towards the center of the winding disk 2. When the winding operation is performed, the drive motor 43 drives the linkage disk 41 to rotate, and the linkage disk 41 drives the sliding block 22 to slide away from the center of the winding disk 2 through the connecting rod 42.

[0059] Reference Figure 2 , Figure 3 and Figure 4A drive disk 5 is coaxially fixed to the output shaft of the drive motor 43. An arc-shaped groove 51 is formed on the drive disk 5, with the center of curvature of the groove located at the center of the drive disk 5. A drive rod 24 is fixedly connected to the winding disk 2, eccentrically positioned with respect to the winding disk 2. The drive rod 24 extends into the arc-shaped groove 51 and slides into it. Initially, the drive rod 24 is located at one end of the arc-shaped groove 51. When the drive motor 43 operates, the drive disk 5 rotates, and the drive rod 24 gradually moves to the other end of the arc-shaped groove 51.

[0060] During the winding operation, the drive motor 43 is activated, and the linkage disk 41 and drive disk 5 rotate synchronously. The linkage disk 41 drives the sliding block 22 to slide away from the center of the winding disk 2, and the drive disk 5 slides relative to the drive rod 24. The drive rod 24 moves from one end of the arc groove 51 to the other end. Then, when the drive disk 5 rotates, it drives the winding disk 2 to rotate synchronously, thereby winding the filament. After winding is completed, the sliding block 22 will reset under the action of the compression spring 211. The sliding block 22 drives the linkage disk 41 to rotate through the connecting rod 42, and the linkage disk 41 will rotate synchronously with the drive disk 5, so that the positions of the drive disk 5 and the drive rod 24 are reset. After the sliding block 22 drives the winding rod 3 to reset, the industrial filament is loosened on the winding rod 3, making it easy for the staff to take it out.

[0061] The rotating sleeve 23 not only forms a rotational engagement with the output shaft of the drive motor 43, but also a sliding engagement between them. That is, the rotating sleeve 23 can slide along the length direction of the output shaft of the drive motor 43. The base plate 1 is provided with a limiting member to restrict the rotation of the winding disc 2. When the drive disc 5 rotates and drives the sliding block 22 to slide, it can prevent the linkage disc 41 from rotating along with it, thereby affecting the sliding effect of the sliding block 22. The bottom wall of the arc groove 51 is wedge-shaped, meaning there is a certain displacement difference between the two ends of the arc groove 51 in the horizontal direction. In the initial state, the drive rod 24 is located at the lower end of the arc groove 51. When the drive disk 5 rotates, the drive rod 24 gradually slides along the lower end of the arc groove 51 to the higher end. At this time, the winding disk 2 will slide away from the linkage disk 41 on the output shaft of the drive motor 43 and release the restriction of the limiting member, thus not affecting the synchronous rotation of the winding disk 2 and the drive disk 5. The base plate 1 is also provided with a reset component 6 that makes the winding disk 2 slide and reset towards the linkage disk 41.

[0062] Reference Figure 1 and Figure 2 The limiting component is an internal gear ring 7, which is fixedly installed on the base plate 1 and located on the periphery of the winding disc 2. An external gear ring 25 is fixedly connected to the outer periphery of the winding disc 2. In the initial state, the internal gear ring 7 and the external gear ring 25 are engaged and locked, and the external gear ring 25 and the internal gear ring 7 form a sliding fit in the horizontal direction.

[0063] Reference Figure 1 , Figure 2 and Figure 5 A mounting plate 12 is fixedly installed on the base plate 1. The mounting plate 12 is located on the side of the winding disc 2 away from the linkage disc 41. A sliding sleeve 8 is fixedly installed on the mounting plate 12. The sliding sleeve 8 has an insertion groove 81. The reset assembly 6 includes a sliding rod 61, an abutment wheel 62, and a first reset spring 63. The sliding rod 61 is inserted into and slides with the insertion groove 81 of the sliding sleeve 8. The sliding direction of the sliding rod 61 is consistent with the sliding direction of the winding disc 2. A limiting port 82 is formed at the opening of the insertion groove 81 of the sliding sleeve 8. One end of the sliding rod 61 inside the sliding sleeve 8 is integrally formed with a limiting plate 611. The first reset spring 63 is located inside the sliding sleeve 8. The length direction of the first reset spring 63 is consistent with the sliding direction of the sliding rod 61. One end of the first reset spring 63 is connected to the bottom wall of the sliding sleeve 8, and the other end of the first reset spring 63 is connected to the limiting plate 611. One end of the sliding rod 61 extends out of the sliding sleeve 8, and the abutting wheel 62 is rotatably connected to the end of the sliding rod 61 located outside the sliding sleeve 8. The winding disc 2 has a rolling ring groove 26 on the side near the abutting wheel 62, and the abutting wheel 62 rolls in the rolling ring groove 26.

[0064] Initially, the first return spring 63 is in an extended state, and the limiting plate 611 abuts against the limiting opening 82. When the winding disc 2 slides and disengages from the inner gear ring 7, the first return spring 63 is compressed. When the winding disc 2 rotates, the abutting wheel 62 rolls in the rolling ring groove 26. After the winding operation is completed, the compression spring 211 drives the sliding block 22 to slide, thereby causing the linkage disc 41 and the drive disc 5 to rotate. At the same time, under the action of the first return spring 63, the winding disc 2 slides, so that the drive rod 24 always abuts against the bottom wall of the arc groove 51, thereby resetting all structures and waiting for the next winding operation. In practice, the number of rotations of the winding disc 2 is fixed to ensure that the length of the wound wire harness is approximately uniform. At the same time, it also ensures that the outer gear ring 25 and the inner gear ring 7 on the winding disc 2 can slide and fit together without misalignment, which would prevent insertion.

[0065] Reference Figure 1 , Figure 6 and Figure 7 The winding disc 2 has three mounting slots 27, which correspond one-to-one with three sliding slots 21. A limit rod 9 is slidably installed in the mounting slot 27. A limit slot 222 is opened on the side wall of the sliding block 22. A limit component 10 is provided on the winding disc 2 to drive the limit rod 9 to slide. The limit component 10 drives the limit rod 9 to slide and is inserted into the limit slot 222.

[0066] During the winding operation, the winding disc 2 rotates. During the rotation, the compression spring 211 may float, causing the winding rod 3 to float, resulting in poor winding effect. By using the insertion of the limiting rod 9 and the limiting groove 222, the sliding block 22 is limited, which helps to prevent the sliding block 22 from sliding in the sliding groove 21, thereby helping to ensure the winding effect of the filament bundle.

[0067] Reference Figure 2 , Figure 6 and Figure 7 The limiting component 10 corresponds to three sliding blocks 22. Taking one of them as an example, the limiting component 10 includes a linkage gear 101, a first sprocket 102, a second sprocket 103, a chain 104, and a limiting gear 105. The linkage gear 101 is rotatably connected to the edge of the winding disc 2, and is located on the side of the winding disc 2 closer to the linkage disc 41. When the winding disc 2 slides away from the linkage disc 41, the outer gear ring 25 disengages from the inner gear ring 7, and the linkage gear 101 meshes with the inner gear ring 7. The first sprocket 102 is rotatably connected in the mounting groove 27, and the first sprocket 102 and the linkage gear 101 rotate coaxially. The second sprocket 103 is rotatably connected in the mounting groove 27. Within 7, chain 104 is wound around first sprocket 102 and second sprocket 103, and limiting gear 105 rotates coaxially with second sprocket 103; winding disc 2 is located in mounting groove 27 and is also slidably connected to limiting rack 28, limiting rod 9 is fixedly connected to limiting rack 28, and the length direction of limiting rack 28 is perpendicular to the length direction of limiting rod 9; first helical tooth 281 is formed on limiting rack 28, and second helical tooth 1051 is formed on limiting gear 105. When limiting gear 105 rotates, under the action of the inclined surface of second helical tooth 1051 and the inclined surface of first helical tooth 281, limiting rack 28 slides away from limiting gear 105, that is, drives limiting rod 9 to insert into limiting groove 222.

[0068] When the winding disc 2 slides, the linkage gear 101 meshes with the internal gear ring 7. When the winding disc 2 rotates, the linkage gear 101 moves on the internal gear ring 7, that is, the linkage gear 101 rotates, which in turn drives the limit rod 9 to slide.

[0069] Reference Figure 7 and Figure 8The winding disc 2 is located within the mounting groove 27 and is equipped with a reset component. The reset component includes a second reset spring 20. A connecting groove 30 is formed within the winding disc 2, connecting the mounting groove 27 to the sliding groove 21. The limiting rod 9 is inserted into and slides into the connecting groove 30. The second reset spring 20 is sleeved around the periphery of the limiting rod 9. One end of the second reset spring 20 is connected to the limiting rack 28, and the other end is connected to the opening of the connecting groove 30. After the winding operation is completed, under the action of the second reset spring 20, the limiting rack 28 slides towards the limiting gear 105 and engages with it, thus disengaging the limiting rod 9 from the limiting groove 222. At this time, the sliding block 22 can slide under the action of the compression spring 211.

[0070] The limiting rod 9 has a sliding groove 91, the length direction of the sliding groove 91 is perpendicular to the length direction of the limiting rod 9. The limiting rod 9 slides in the sliding groove 91 and is engaged with the limiting pin 92. The limiting rod 9 is provided with an abutment spring 93 in the sliding groove 91. One end of the abutment spring 93 is connected to the bottom wall of the sliding groove 91, and the other end of the abutment spring 93 is connected to the limiting pin 92. A wedge-shaped surface is formed on the upper side of the limiting pin 92. The sliding block 22 is provided with a pre-tightening groove 223 on the side wall of the limiting groove 222. After the limiting rod 9 is engaged with the limiting groove 222, the sliding groove 21 and the pre-tightening groove 223 are connected. Under the action of the abutment spring 93, the limiting pin 92 enters the pre-tightening groove 223, further locking the limiting rod 9 and the sliding block 22. Because there is a gap between the second helical teeth 1051 when the limiting gear 105 rotates, the limiting rack 28 will have a reciprocating slippage phenomenon. Therefore, the limiting pin 92 is used to lock the limiting rod 9. In this way, the speed at which the limiting rack 28 slides towards the limiting gear 105 can be slowed down. Since the limiting gear 105 rotates relatively fast, it ensures that the limiting rack 28 will not have a large-scale reciprocating slippage, which helps to prevent the limiting rod 9 from disengaging from the limiting groove 222. After the winding is completed, the limiting gear 105 stops rotating. Under the action of the second return spring 20, the limiting rod 9 slides outward. At this time, the limiting pin 92 will also slide into the sliding groove 91 under the action of the wedge surface.

[0071] The implementation principle of a production process for colored polyester industrial yarn according to an embodiment of this application is as follows: During the winding operation, the drive motor 43 is operated, and the number of rotations of the drive motor 43 is fixed each time. The linkage disk 41 and the drive disk 5 rotate synchronously first. The linkage disk 41 drives the sliding block 22 to slide away from the center of the winding disk 2 through the connecting rod 42. The drive disk 5 and the drive rod 24 slide relative to each other. The drive rod 24 moves to the other end of the arc groove 51, and the drive rod 24 will drive the winding disk 2 to slide, releasing the lock with the internal gear ring 7. Then the drive disk 5 drives the winding disk 2 to rotate synchronously, realizing the winding action of the yarn bundle; after the winding disk 2 slides, The linkage gear 101 meshes with the internal gear ring 7, causing the linkage gear 101 to rotate. This rotation, through the first sprocket 102, the second sprocket 103, and the chain 104, drives the limiting gear 105 to rotate, thereby causing the limiting rod 9 to slide and engage with the limiting groove 222, thus locking the sliding block 22. After winding is completed, the limiting rod 9 returns to its original position and disengages from the limiting groove 222. Under the action of the first return spring 63 and the compression spring 211, both the winding disc 2 and the winding rod 3 return to their original positions. After the winding rod 3 returns to its original position, the circumference diameter formed by the three winding rods 3 becomes smaller, making the wire bundle looser on the winding rod 3, which makes it easier for workers to remove the wire bundle.

[0072] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
