AI Technical Summary
The existing polyester filament tow post-drawing production line suffers from uneven fiber tension during the collection process, leading to fiber breakage, decreased orientation and mechanical properties, and difficulty in collection control, which affects product quality and production efficiency.
The system employs a winding mechanism and an auxiliary mechanism. A cylinder drives the active and driven gears to rotate the upright frame. In conjunction with a motor-driven disc and protrusions to move the grooved strips, the position of the winding drum and the cyclic movement of the carriage are achieved. This ensures that the polyester filament bundle maintains uniform and stable tension during collection. Furthermore, a combing mechanism prevents tangling and improves the uniformity of winding.
It achieves uniform tension control of polyester filament bundles during the collection process, avoiding loosening, knotting or tangling, improving product quality and appearance, reducing defect rate and increasing production efficiency.

Description
Technical Field
[0001] This invention relates to the field of textile machinery technology, specifically to a polyester filament tow post-drawing production line. Background Technology
[0002] The polyester tow post-drawing production line is a specialized production line for post-drawing polyester tows. Post-drawing is a process of further stretching the fibers to improve their orientation and mechanical properties. The main components of this production line include a post-drawing unit, a crimping unit, a drying chamber, a traction platform, and a take-up hopper. A review of the public announcement (CN215051003U) reveals a polyester filament tow post-drawing production line. This technology discloses "a polyester filament tow post-drawing production line, including a work platform and a pre-dust removal box. The pre-dust removal box is fixedly connected to the upper left side of the work platform. The pre-dust removal box includes an outer casing, guide rollers, a negative pressure fan, an inner casing, a clamping block, a dust baffle, a handle, a top cover, a guide tube, a dust collection hopper, an air inlet pipe, and dust removal filament balls. The guide rollers and the inner casing are installed on the inner side wall of the outer casing." The device features a negative pressure fan installed on the left side of the inner casing, and a duct connected to the right side of the inner casing. The end of the duct is fixedly connected to a dust collection bucket. This design achieves the following technical benefits: "By pressing the negative pressure fan switch, the negative pressure fan operates inside the inner casing to create a negative pressure environment. The dust adhering to the polyester filaments is adsorbed through the connected duct and the dust collection bucket. The dust filter screen filters the dust in the air, and the staff can periodically open the top cover handle to clean the dust filter screen for convenient subsequent use." While direct collection of processed polyester filaments into the take-up bin simplifies the production process thanks to the precise guidance and control of the traction platform, it also introduces several potential problems. The tension differences between fibers caused by friction and stretching can lead to breakage of some fibers due to excessive tension, or insufficient tension affecting the orientation and mechanical properties of other fibers. Furthermore, direct collection makes fiber quantity control difficult, potentially resulting in inappropriate bin capacity – either overfilling, affecting fiber quality, or underfilling, impacting production efficiency and causing inconvenience for production and management.

[0012] This invention provides a polyester filament tow post-drawing production line. Compared with the prior art, it has the following advantages: (1) The extension frame is driven by the output end of the cylinder to drive the drive gear to rotate. The drive gear drives the upright frame to rotate through the driven gear, so that the upright frame can drive the position of the take-up drum to adjust slightly. This allows the take-up drum to adjust the tension during the winding of the polyester filament bundle, ensuring that the polyester filament bundle maintains uniform and stable tension during the collection process, thereby avoiding problems such as loosening, knotting or tangling. This helps to improve the overall quality and appearance of the product and reduce the defect rate.
[0013] (2) The output end of the second motor drives the disc to rotate. The disc moves the slide along the inside of the guide rail by pushing the first groove strip through the protrusion. When the protrusion disengages from the first groove strip, it pushes the second groove strip to move the slide along the inside of the guide rail. The output end of the second motor rotates continuously, which can drive the slide to move back and forth in a cycle. This allows the polyester filament bundle to be evenly wound on the winding drum, avoiding wrinkles, overlaps or loosening during the winding process, and improving the quality of the finished product.
[0014] (3) Before entering the winding mechanism on the workbench, the treated polyester filament bundle is combed by the sliver sliver rack, which effectively prevents the polyester filament bundle from being easily twisted in the previous step of the stretching process.

[0017] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0018] Please see Figure 1-6 This invention provides a technical solution for a polyester filament tow post-drawing production line: a polyester filament tow post-drawing production line, including a workbench 1, characterized in that: a winding mechanism 2 is provided on the workbench 1 for tensioning the polyester filament tow during winding; an auxiliary mechanism 3 is provided on the workbench 1 for cooperating with the winding mechanism 2 to uniformly wind the polyester filament tow; the winding mechanism 2 includes: The winding assembly 21 includes a bracket 211 mounted on the workbench 1. Both sides of the rear end of the bracket 211 are pivotally connected to uprights 212. A winding drum 213 is installed between the uprights 212 on both sides. A driven gear 214 is fixed to the lower end of the outer surface of one of the uprights 212. The tensioning assembly 22 includes an extension frame 221 rotatably mounted on the rear end of one side of the bracket 211. A drive gear 222 is fixed on the upper outer surface of the extension frame 221, and the drive gear 222 meshes with the driven gear 214 for transmission. A shaft frame 223 is fixed on the front end of one side of the bracket 211, and a cylinder 224 is pivotally connected to the shaft frame 223. The output end of the cylinder 224 is pivotally connected to the lower end of the extension frame 221.
[0019] In this embodiment, the output end of the cylinder 224 drives the extension frame 221 to rotate the drive gear 222. The drive gear 222 drives the upright frame 212 to rotate through the driven gear 214, so that the upright frame 212 can drive the position of the take-up drum 213 to be adjusted slightly. This allows for tension adjustment of the take-up drum 213 during the winding of the polyester filament bundle, ensuring that the polyester filament bundle maintains uniform and stable tension during collection, thereby avoiding problems such as loosening, knotting, or tangling. This helps to improve the overall quality and appearance of the product and reduce the defect rate.
[0020] Specifically, auxiliary mechanism 3 includes: The moving component 31 includes a guide rail frame 311 fixed to the bottom of the workbench 1, a slide 312 slidably installed inside the guide rail frame 311, and a first groove strip 313 and a second groove strip 314 respectively fixed to the inner walls of the left and right ends of the slide 312. The drive assembly 32 includes a disk 321 disposed on the moving assembly 31. Four equally spaced protrusions 322 are fixed on one side of the top outer edge of the disk 321. A mounting bracket 323 is fixed in the middle of the bottom of the guide rail frame 311. A second motor 324 is mounted in the middle of the bottom of the mounting bracket 323, and the output end of the second motor 324 is connected to the axis of the disk 321.
[0021] In this embodiment, the output end of the second motor 324 drives the disk 321 to rotate. The disk 321 moves the first groove strip 313 through the protrusion 322, causing the slide 312 to move along the inside of the guide rail frame 311. When the protrusion 322 disengages from the first groove strip 313, it moves the second groove strip 314 to move the slide 312 along the inside of the guide rail frame 311. This allows the output end of the second motor 324 to rotate continuously, driving the slide 312 to move back and forth in a cycle, so that the polyester filament bundle can be evenly wound onto the take-up drum 213.
[0022] Specifically, the auxiliary mechanism 3 also includes two rollers 33 that are rotatably mounted at both ends of the slide 312, and the rollers 33 are located inside the guide rail frame 311.
[0023] In this embodiment, the carriage 312 moves along the interior of the guide rail 311 via the rollers 33, thereby improving the smoothness of the movement process.
[0024] Specifically, the winding mechanism 2 also includes a first motor 23 mounted on the upper part of the outer surface of one of the uprights 212 and used to drive the winding drum 213 to rotate.
[0025] In this embodiment, the polyester filament bundle is wound up and collected by the winding drum 213 driven by the output end of the first motor 23.
[0026] Specifically, the winding mechanism 2 also includes a mounting base 24 fixed to the bottom of the bracket 211, and the bottom of the mounting base 24 is fixed to the top of the slide 312. The worktable 1 has a sliding groove 9 inside, and the slide 312 is slidably installed with the worktable 1 through the sliding groove 9.
[0027] In this embodiment, the auxiliary mechanism 3 drives the winding mechanism 2 on the worktable 1 to move as a whole through the mounting base 24.
[0028] Specifically, a combing mechanism 4 is provided on the workbench 1. The combing mechanism 4 includes a base frame 41 fixed to the front end of the top of the workbench 1, and a sliver slattering frame 42 is fixed to the upper end of the base frame 41.
[0029] In this embodiment, the processed polyester filament bundle is combed by the sliver sliver 42 before entering the winding mechanism 2 on the workbench 1, which effectively avoids the polyester filaments that are pulled in the previous step of the stretching process from easily becoming tangled.
[0030] Specifically, a traction mechanism 5 is provided on the front side of the workbench 1, and a drying mechanism 6 is installed on the upper end of the traction mechanism 5. A curling mechanism 7 is provided on the front side of the traction mechanism 5, and a stretching mechanism 8 is provided in front of the curling mechanism 7.
[0031] In this embodiment, the polyester filament bundle is stretched by the stretching mechanism 8, which stretches the fiber by external force, increasing its length and decreasing its diameter, which helps to improve the fiber orientation and mechanical properties. Then, the stretched polyester filament bundle is crimped by the crimping mechanism 7, which increases the fiber's bulkiness and cohesion, helping to improve the fiber's covering ability and warmth retention. The crimped polyester filament bundle enters the drying mechanism 6 for drying, where the moisture in the fiber is evaporated by heating and ventilation to achieve the required degree of dryness. Then, it enters the traction platform, which is equipped with traction rollers to guide and control the fiber's direction. Finally, the processed polyester filament bundle enters the winding mechanism 2 on the worktable 1 for collection.
[0032] The working principle and usage process of this invention are as follows: First, the polyester filament bundle is stretched by the stretching mechanism 8, which stretches the fiber by external force to increase its length and decrease its diameter. Then, the stretched polyester filament bundle is crimped by the crimping mechanism 7. The crimped polyester filament bundle will enter the drying mechanism 6 for drying, and then enter the traction platform to guide and control the fiber direction. Finally, the processed polyester filament bundle will enter the winding mechanism 2 on the worktable 1 for collection. In addition, before entering the winding mechanism 2 on the worktable 1, the processed polyester filament bundle is combed by the sliver sliver 42, which effectively avoids the polyester filaments pulled in the previous step of stretching the polyester filament bundle from becoming tangled. After the processed polyester filament bundle enters the winding mechanism 2, the winding drum 213 is driven by the output end of the first motor 23 to wind and collect the polyester filament bundle. The extension frame 221 is driven by the output end of the cylinder 224 to drive the drive gear 222 to rotate. The drive gear 222 drives the upright frame 212 to rotate through the driven gear 214, so that the upright frame 212 can drive the position of the winding drum 213 to be adjusted slightly, thereby adjusting the tension of the winding drum 213 during the winding of the polyester filament bundle. Meanwhile, the output end of the second motor 324 drives the disc 321 to rotate. The disc 321 moves the first groove strip 313 through the protrusion 322, causing the slide 312 to move along the inside of the guide rail frame 311. When the protrusion 322 disengages from the first groove strip 313, it moves the second groove strip 314 to move the slide 312 along the inside of the guide rail frame 311. This allows the output end of the second motor 324 to rotate continuously, driving the slide 312 to move back and forth in a cycle, so that the polyester filament bundle can be evenly wound onto the take-up drum 213.
