Description

Technical Field

[0001] This utility model relates to the field of polyester filament production technology, and in particular to a device for preparing flame-retardant polyester filament. Background Technology

[0002] Polyester is an important type of synthetic fiber, and is the commercial name for polyester fiber. It is a fiber-forming polymer produced by esterification or transesterification and polycondensation of purified terephthalic acid or dimethyl terephthalate and ethylene glycol, followed by spinning and post-treatment. Polyester yarn is characterized by its resistance to chemicals and frequent washing, reducing fading and discoloration in clothing. Therefore, it is used in hotel uniforms, stonewashed denim, sportswear, and children's clothing. Relatively speaking, polyester yarn is more durable than rayon. When embroidering, the high-speed operation of the machine allows the high-tenacity polyester yarn to withstand significant tensile force; moreover, it has extremely high fire resistance; even when the garment is near a flame, it is not easily ignited.

[0003] The preparation of flame-retardant polyester yarn requires the assistance of various equipment, including a splitting device and an antistatic device. The splitting device primarily divides large rolls of polyester yarn into smaller rolls; however, existing polyester yarn splitting devices have certain shortcomings.

[0004] First, existing cutting devices cannot adjust the tension of the polyester filaments during use. If the polyester filaments are too loose, the wound polyester filaments will become tangled and difficult to process.

[0005] Secondly, existing polyester filaments cannot be fixed during cutting, and the cut edge will spring back, making it difficult to find the break. Utility Model Content

The fixing teeth and the fixing grooves are adapted to each other, and both the fixing teeth and the fixing grooves are isosceles trapezoids.

[0009] Preferably, the top outer wall of the support plate is provided with an anti-slip pad, which is adapted to the support plate and the fixing groove respectively, and both the anti-slip pad and the fixing teeth are anti-slip rubber structures.

[0010] Preferably, both ends of the outer wall of the back plate are provided with adjustment grooves, the adjustment block is slidably connected to the inner wall of the adjustment groove, a threaded rod is rotatably installed on the inner wall of the adjustment groove, the threaded rod is adapted to the adjustment groove, and the threaded rod and the adjustment block are rotatably connected by a thread.

[0011] Preferably, the outer wall of the back plate is provided with a drive groove, and a first servo motor is installed on the inner wall of the drive groove. The output shaft of the first servo motor is connected to a threaded rod.

[0012] Preferably, the mounting assembly includes mounting rods slidably mounted on both ends of the top outer wall of the base plate. Rotating grooves are formed at both ends of the outer walls of the mounting rods and the outer walls of the back plate. A rotating disk is rotatably mounted on the inner wall of each rotating groove. An mounting roller is inserted into the rotating disk. Mounting grooves are formed on both sides of the outer walls of the mounting rollers. A mounting block is provided on the outer wall of the rotating disk. Both the mounting block and the mounting groove are square structures. A second servo motor is bolted to the outer wall of the mounting rod on the side away from the rotating disk. The output shaft of the second servo motor is connected to the rotating disk.

[0013] Preferably, the bottom plate has movable grooves at both ends of its top outer wall, and the mounting rod is slidably connected to the inner wall of the movable groove.

[0015] In summary, the technical effects and advantages of this utility model are as follows:

[0016] 1. In this utility model, during the polyester filament splitting process, the adjusting block slides up and down along the back plate, driving the adjusting roller to rise or fall, thereby adjusting the tension of the polyester filament. The polyester filament is more tightly wound and less prone to loosening. When the polyester filament needs to be cut, the first electric telescopic rod drives the fixing plate to descend and merge with the support plate to fix the polyester filament.

[0017] 2. In this utility model, when the polyester filament is fixed, the fixing teeth descend and embed into the fixing groove to press the polyester filament in place. At the same time, the anti-slip pad increases friction with the fixing teeth, making the polyester filament less likely to fall off and more stable.

[0018] 3. In this utility model, after installation, the first end of the polyester filament is located and passed through the adjustment component and the fixing component in sequence. Finally, it is fixed on the installation roller that is not wrapped with polyester filament. Then, the second servo motor drives the rotating disk to rotate, which in turn drives the installation roller to rotate. At this time, polyester filament is gradually wrapped on the installation roller that is not wrapped with polyester filament, and the number of installation rollers with polyester filament wrapped on the other end gradually decreases, thereby dividing the polyester filament and making the operation more convenient. The second electric telescopic rod drives the installation rod to slide along the moving groove, thereby adjusting the distance between the installation rod 15 and the back plate, which facilitates the installation and disassembly of the installation roller.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example: Reference Figure 1-4 The apparatus shown is for preparing flame-retardant polyester filament, comprising a base plate 1, a back plate 2 welded to one end of the top outer wall of the base plate 1, the back plate 2 being adapted to the base plate 1, mounting components being provided at both ends of the outer walls of the base plate 1 and the back plate 2, and adjusting components being provided at both ends of the outer wall of the back plate 2, the adjusting components being located between the mounting components and adapted to the mounting components, a fixing component being provided in the middle of the back plate 2, the fixing component being adapted to the adjusting components, the adjusting component including an adjusting block 3 slidably mounted on the outer wall of the back plate 2, an adjusting roller 4 rotatably mounted on the outer wall of the adjusting block 3, the adjusting roller 4 being adapted to the adjusting block 3, the fixing component including a support plate 5 welded to the outer wall of the back plate 2, a mounting plate 6 welded to the middle position of the top outer wall of the back plate 2, a mounting hole being opened on the outer wall of the mounting plate 6, a first electric telescopic rod 7 being installed on the inner wall of the mounting hole, and a fixing plate 8 being installed at the end of the first electric telescopic rod 7 by bolts, the fixing plate 8 being adapted to the support plate 5.

[0027] With the above structure: During operation, the polyester filaments to be split are fixed on the mounting component on one side. Then, the polyester filaments are passed sequentially through the top of the adjusting component on one side, between the fixing components, and below the adjusting component on the other side, and finally fixed on the mounting component at the other end. As the mounting component rotates, the mounting component on the other side winds the polyester filaments. When the wound polyester filaments meet certain conditions, the mounting component stops rotating. Then, the fixing component fixes the polyester filaments, and then the polyester filaments are cut near the mounting component on the winding side, completing the splitting of the polyester filaments. During the splitting process, the adjusting block 3 slides up and down along the back plate 2, driving the adjusting roller 4 to rise or fall, adjusting the tension of the polyester filaments. The polyester filaments are wound more tightly and are less likely to loosen. When the polyester filaments need to be cut, the first electric telescopic rod 7 drives the fixing plate 8 to descend and merge with the support plate 5 to fix the polyester filaments. After the polyester filaments are cut, the cut polyester filaments can be retained without having to find the break point again, saving time for reconnecting the polyester filaments and making it more convenient to use.

[0028] like Figure 3 As shown, the bottom outer wall of the fixing plate 8 is provided with fixing teeth 9 distributed at equal intervals, and the top outer wall of the support plate 5 is provided with fixing grooves 10 distributed at equal intervals. The fixing teeth 9 and the fixing grooves 10 are adapted to each other. Both the fixing teeth 9 and the fixing grooves 10 are isosceles trapezoids. The top outer wall of the support plate 5 is provided with anti-slip pads 11, which are adapted to the support plate 5 and the fixing grooves 10 respectively. Both the anti-slip pads 11 and the fixing teeth 9 are anti-slip rubber structures. When the polyester filament is fixed, the fixing teeth 9 descend and embed into the fixing grooves 10 to press the polyester filament. At the same time, the anti-slip pads 11 and the fixing teeth 9 increase the friction, making it less likely for the polyester filament to fall off and more stable.

[0029] like Figure 2 As shown, both ends of the outer wall of the back plate 2 are provided with adjustment grooves 12. The adjustment block 3 is slidably connected to the inner wall of the adjustment groove 12. A threaded rod 13 is rotatably installed on the inner wall of the adjustment groove 12. The threaded rod 13 is adapted to the adjustment groove 12. The threaded rod 13 and the adjustment block 3 are connected by a threaded rotation. The outer wall of the back plate 2 is provided with a drive groove. A first servo motor 14 is installed on the inner wall of the drive groove. The output shaft of the first servo motor 14 is connected to the threaded rod 13. When the adjustment roller 4 moves, the first servo motor 14 drives the threaded rod 13 to rotate, thereby moving the adjustment block 3 up and down to adjust the tension length of the polyester yarn, making the operation more convenient.

[0030] like Figure 4As shown, the mounting assembly includes mounting rods 15 slidably mounted on both ends of the top outer wall of the base plate 1. Rotating grooves are provided at both ends of the outer wall of the mounting rods 15 and the outer wall of the back plate 2. A rotating disk 16 is rotatably mounted on the inner wall of the rotating groove. An mounting roller 17 is inserted into the rotating disk 16. Mounting grooves are provided on both sides of the outer wall of the mounting roller 17. Mounting blocks are provided on the outer wall of the rotating disk 16. Both the mounting blocks and the mounting grooves are square structures. A second servo motor 18 is bolted to the outer wall of the mounting rod 15 on the side away from the rotating disk 16. The output shaft of the second servo motor 18 is connected to the rotating disk 16. (The last sentence appears to be incomplete and possibly refers to a separate process: "When polyester filaments are being cut...") Install one of the mounting rollers 17 with polyester filaments wound on it, and then install the other mounting roller 17 without polyester filaments wound on it. After installation, locate the beginning of the polyester filament and pass it through the adjustment component and the fixing component in sequence. Finally, fix it on the mounting roller 17 without polyester filaments wound on it. Then, the second servo motor 18 drives the rotating disk 16 to rotate, which in turn drives the mounting roller 17 to rotate. At this time, polyester filaments are gradually wound on the mounting roller 17 without polyester filaments wound on it, while the number of mounting rollers 17 with polyester filaments wound on the other end gradually decreases, thereby dividing the polyester filaments and making the operation more convenient.

[0031] like Figure 4 As shown, both ends of the top outer wall of the base plate 1 are provided with movable grooves 19. The mounting rod 15 is slidably connected to the inner wall of the movable groove 19. Both ends of the top outer wall of the base plate 1 are provided with control grooves 20. The control grooves 20 are adapted to the movable grooves 19. The length of the control grooves 20 is greater than the length of the movable grooves 19. A second electric telescopic rod 21 is installed on the inner wall of the control grooves 20. The end of the second electric telescopic rod 21 is connected to the mounting rod 15. The second electric telescopic rod 21 drives the mounting rod 15 to slide along the movable grooves 19, thereby adjusting the distance between the mounting rod 15 and the back plate 2, which facilitates the installation and disassembly of the mounting roller 17.

[0032] The working principle of this practical application is as follows:

[0033] During operation, the polyester filaments to be split are fixed on the mounting component on one side. Then, the polyester filaments are passed sequentially through the top of the adjusting component on one side, between the fixing components, and below the adjusting component on the other side. Finally, they are fixed on the mounting component at the other end. As the mounting component rotates, the mounting component on the other side winds the polyester filaments. When the wound polyester filaments meet certain conditions, the mounting component stops rotating. Then, the fixing component fixes the polyester filaments. Finally, the polyester filaments are cut near the mounting component on the winding side, completing the splitting of the polyester filaments. During the splitting process, the adjusting block 3 slides up and down along the back plate 2, driving the adjusting roller 4 to rise or fall, adjusting the tension of the polyester filaments. The polyester filaments are wound more tightly and are less likely to loosen. When the polyester filaments need to be cut, the first electric telescopic rod 7 drives the fixing plate 8 to descend and merge with the support plate 5 to fix the polyester filaments. After the polyester filaments are cut, the cut polyester filaments can be retained without having to find the cut end of the polyester filaments again, saving time for reconnecting the polyester filaments and making it more convenient to use.

[0034] When the polyester filament is fixed, the fixing teeth 9 descend and embed into the fixing groove 10 to press the polyester filament in place. At the same time, the anti-slip pad 11 increases the friction with the fixing teeth 9, making the polyester filament less likely to fall off and more stable. When the adjusting roller 4 moves, the first servo motor 14 drives the threaded rod 13 to rotate, which in turn moves the adjusting block 3 up and down to adjust the tension length of the polyester filament, making the operation more convenient.

[0035] After installation, locate the first end of the polyester filament and pass it through the adjustment component and the fixing component in sequence. Finally, fix it on the installation roller 17 without polyester filament. Then, the second servo motor 18 drives the rotating disk 16 to rotate, which in turn drives the installation roller 17 to rotate. At this time, polyester filament is gradually wrapped around the installation roller 17 without polyester filament, and the installation roller 17 with polyester filament wrapped at the other end gradually decreases, thereby dividing the polyester filament and making the operation more convenient. The second electric telescopic rod 21 drives the installation rod 15 to slide along the moving groove 19, thereby adjusting the distance between the installation rod 15 and the back plate 2, which facilitates the installation and disassembly of the installation roller 17.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
