Abstract
Description
Technical Field
[0001] This utility model relates to the field of polyester staple fiber technology, and in particular to a stretching device for producing high-gloss polyester staple fiber. Background Technology
[0002] The stretching equipment used in the production of high-gloss polyester staple fiber is one of the key pieces of equipment in the polyester staple fiber production process. Polyester staple fiber is an important type of synthetic fiber. It is a fiber-forming polymer—polyethylene terephthalate (PET)—obtained from purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) through esterification or transesterification and polycondensation reactions. Fibers are then produced through spinning and post-processing. Stretching is a crucial step in the production of polyester staple fiber. The purpose of stretching is to improve the fiber's orientation and crystallinity, thereby increasing its strength, modulus, and dimensional stability, while also improving its gloss and hand feel. The performance of the stretching equipment directly affects the quality and production efficiency of the polyester staple fiber.
[0003] Some production lines can only produce a single type of polyester staple fiber, lacking flexibility and unable to quickly adapt to changes in market demand. Furthermore, they cannot dissipate heat from the stretched polyester staple fiber, leading to changes in its quality. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a stretching device for producing high-gloss polyester staple fibers.
[0005] This utility model is achieved by the following technical solution: a stretching device for producing high-gloss polyester staple fiber, including a working box, the right end of which is fixedly connected to the left end of a support plate, the bottom end of which is fixedly connected to the top end of a cooling fan, and four cooling fans are provided, which are positioned directly above the discharge port.
[0006] Through the above technical solution, the working box provides a closed working environment, protecting the internal parts from external interference and preventing the fibers from being contaminated during the stretching process. The support plate supports the cooling fan to ensure its stable operation and help improve the heat dissipation effect. The cooling fan dissipates heat from the stretched polyester staple fibers to prevent the fibers from being affected by overheating.
[0007] As a further improvement to the above solution, the front end of the work box is fixedly connected to the rear end of the protective baffle, the front end of the protective baffle is fixedly connected to the rear end of the connecting plate, and the front end of the connecting plate is fixedly connected to the rear end of the control panel.
[0008] Through the above technical solutions, the protective baffle protects operators from injury by the internal moving parts of the equipment, thereby improving operational safety.
[0009] As a further improvement to the above solution, an observation window is provided at the front end of the protective baffle, and a feed inlet is provided at the left end of the working box.
[0010] The above technical solution allows operators to easily observe the internal working conditions of the equipment, such as the stretching state of the fibers and the operation of the equipment components. The feed port is the entry point for polyester staple fibers to enter the equipment, ensuring that the fibers can smoothly enter the working box for subsequent processing.
[0011] As a further improvement to the above solution, a fixing block is fixedly connected to the inner wall of the work box. Four fixing blocks are provided. Guide rollers are drivenly connected to one end of the four fixing blocks that are close to each other. Two guide rollers are provided. The front ends of the two guide rollers are drivenly connected to the rear end of the servo motor through the inside of the four fixing blocks.
[0012] The above technical solution uses a fixed block to fix the guide roller, ensuring the stability of the guide roller during operation, which helps to stretch the fiber smoothly. The guide roller guides the polyester staple fiber in the equipment, ensuring that the fiber is stretched along the predetermined path, reducing fiber deviation and breakage.
[0013] As a further improvement to the above solution, the bottom end of the inner wall of the work box is fixedly connected to the bottom end of the support block, and two support blocks are provided. A drive motor is fixedly connected to the front end of the two support blocks, and two drive motors are provided.
[0014] The above technical solution enables the support block to support the drive motor, ensuring the stability of the drive motor during operation and contributing to the normal operation of the pressure roller.
[0015] As a further improvement to the above solution, the two support blocks are connected to a rotating shaft at their close ends, and four rotating shafts are provided. The four rotating shafts are connected to the rear ends of two drive motors through the interior of the two support blocks. The four rotating shafts are connected to a pressure roller at their close ends, and two pressure rollers are provided. Several guide grooves are opened on the surface of the two pressure rollers, and several heating plates are opened on the inner wall of the several guide grooves. A discharge port is opened at the right end of the working box.
[0016] Through the above technical solution, the rotating shaft connects the drive motor and the pressure roller, transmitting the power of the drive motor to the pressure roller so that the pressure roller can work normally. The pressure roller stretches the polyester staple fiber, and the guide groove and heating plate on the surface improve the gloss and stretching quality of the fiber. After stretching, the polyester staple fiber leaves the outlet of the equipment, ensuring that the fiber can be discharged smoothly.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] This invention features a heating plate installed on the inner wall of the guide groove on the surface of the pressure roller. During the stretching process, the heating plate heats the polyester staple fiber, which helps to improve the molecular arrangement of the fiber, making the fiber surface smoother and flatter, thereby improving the fiber's gloss and meeting the production requirements of high-gloss polyester staple fiber.
[0019] The guide roller is driven by a servo motor through a fixed block. The precise control capability of the servo motor ensures the stability and accuracy of the guide roller rotation, which allows the polyester staple fiber to maintain uniform tension and speed during the stretching process, reducing unevenness in fiber stretching, avoiding fiber breakage or insufficient stretching, and effectively improving the stretching quality of the fiber.
[0020] This invention utilizes four cooling fans positioned directly above the discharge port to specifically dissipate heat from the stretched polyester staple fibers. The stretched fibers may contain heat from previous processing; the cooling fans promptly dissipate this heat, preventing performance changes due to overheating, such as damage to the fiber structure or reduced gloss, thus helping to ensure product quality.
[0021] The protective baffle separates the moving parts inside the work chamber from the operator, improving operational safety. The observation window on the baffle allows the operator to monitor the internal workings of the equipment at any time, such as the fiber tension and the operation of equipment components. The control panel, located at the front of the protective baffle and connected via a connecting plate, allows the operator to easily control the equipment, such as adjusting the parameters of the servo motor and drive motor, further enhancing operational convenience.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0030] Example:
[0031] Please combine Figure 1-5 This embodiment of a stretching device for producing high-gloss polyester staple fiber includes a working box 1. The right end of the working box 1 is fixedly connected to the left end of the support plate 6. The bottom end of the support plate 6 is fixedly connected to the top end of the cooling fan 7. Four cooling fans 7 are provided and are located directly above the discharge port 17.
[0032] The front end of the work box 1 is fixedly connected to the rear end of the protective baffle 2, the front end of the protective baffle 2 is fixedly connected to the rear end of the connecting plate 4, and the front end of the connecting plate 4 is fixedly connected to the rear end of the control panel 5.
[0033] The protective baffle 2 has an observation window 3 at its front end, and the work box 1 has a feed inlet 8 at its left end.
[0034] The inner wall of the working box 1 is fixedly connected with a fixing block 9. There are four fixing blocks 9. The ends of the four fixing blocks 9 that are close to each other are connected to a guide roller 11.
[0035] There are two guide rollers 11, and the front ends of the two guide rollers 11 are connected to the rear end of the servo motor 10 through four fixing blocks 9.
[0036] The bottom of the inner wall of the working box 1 is fixedly connected to the bottom of the support block 12. There are two support blocks 12, and the front ends of the two support blocks 12 are fixedly connected to the drive motors 13. There are two drive motors 13.
[0037] Two support blocks 12 are connected to a rotating shaft 14 at their close ends. There are four rotating shafts 14. The ends of the four rotating shafts 14 that are far apart from each other are connected to the rear ends of two drive motors 13 through the inside of the two support blocks 12. Two pressure rollers 15 are connected to the ends of the four rotating shafts 14 that are close together. Several guide grooves 16 are opened on the surface of the two pressure rollers 15. Several heating plates are opened on the inner wall of the several guide grooves 16. A discharge port 17 is opened at the right end of the working box 1.
[0038] The implementation principle of a high-gloss polyester staple fiber stretching device in this embodiment is as follows: After the polyester staple fiber enters the working box 1 through the feed inlet 8, it first passes through the guide roller 11. The servo motor 10 drives the guide roller 11 to rotate. Due to the cooperation of the guide rollers 11, the incoming fiber can be initially guided and pulled, so that the fiber enters the subsequent stretching process in a predetermined direction. Then, two drive motors 13 drive four rotating shafts 14 to rotate respectively. The rotating shafts 14 drive the pressure rollers 15 to rotate. The fiber passes between the two pressure rollers 15. Due to the difference in the rotation direction and speed of the pressure rollers 15, the fiber is stretched. The surface of the pressure roller 15... The guide groove 16 and the heating plate play a role in this process. The heating plate heats the fiber, making it easier to stretch. The guide groove 16 helps to maintain the position of the fiber during the stretching process and prevents the fiber from shifting. After the polyester staple fiber has passed through the stretching process, it is output from the discharge port 17. Since the fiber may absorb heat during the stretching process, four cooling fans 7 set directly above the discharge port 17 start to work. The cooling fans 7 generate airflow by rotating, which carries away the hot air near the discharge port 17, thereby dissipating heat from the stretched polyester staple fiber, reducing the fiber temperature, and preventing the accumulation of heat from adversely affecting the fiber quality.
[0039] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
