Description

Technical Field

[0001] This utility model relates to the field of drawing equipment technology, specifically a stable polyester colored yarn conveying and drawing equipment. Background Technology

[0002] In the textile and related industries, polyester colored yarn is widely used in the production of many products, such as clothing fabrics, home textiles, and industrial fabrics, due to its excellent properties, such as high strength, abrasion resistance, chemical resistance, and good dyeability. In the production process of polyester colored yarn, the yarn drawing process is a crucial step, directly determining the quality and performance of the final product.

[0003] Traditional polyester filament drawing processes face numerous challenges. During the transformation of raw materials into filamentous polyester, precise control of multiple parameters is crucial to ensure product quality stability. Polyester raw materials generated in the polymerization reactor are extruded into filaments and then enter the drawing stage. At this stage, ensuring the uniformity and stability of the filaments during stretching becomes critical for producing high-quality polyester filaments. Tension plays a decisive role in the polyester filament drawing process. When the tension is too high, the tensile force on the filaments exceeds their tolerance, leading to a smaller filament diameter or even breakage. Fiber breakage not only interrupts production and increases costs but also affects overall product quality and production efficiency. Conversely, if the tension is too low, the filaments cannot fully extend during stretching, resulting in a thicker filament diameter that fails to meet product specifications and reduces market competitiveness. Therefore, precisely controlling the tension within a suitable range is essential for producing polyester filaments with uniform thickness and stable quality.

[0004] In existing production processes, as the amount of material wound by the take-up roller increases, the diameter of the take-up roller gradually increases. According to physical principles, this changes the tension value of the fiber filaments during the winding process. In actual production, because the diameter of the take-up roller is dynamically changing and is affected by a combination of factors such as production speed and raw material characteristics, it is difficult to effectively control the drawing tension value to remain stable at a fixed value. This fluctuation in tension value leads to inconsistent quality of the produced polyester colored yarn, making it difficult to meet the market's growing demand for high-quality products.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Please see Figure 1-4 The present invention provides the following technical solution:

[0026] A stable polyester filament conveying and drawing equipment includes an extrusion unit and a winding unit. A tension adjusting device 1 and a guiding device 2 are installed between the extrusion unit and the winding unit. Below the guiding device 2 is a guiding device motion assembly 3 that drives the guiding device 2 to reciprocate. During production, raw materials are formed into polyester raw materials in a high-temperature, high-pressure polymerization reactor. The polyester raw materials are output to the extrusion unit, heated, melted, and extruded, and then extruded into filaments from the extrusion nozzle below the extrusion unit. The polyester filaments are wound onto the winding roller via the tension adjusting device 1 and the guiding device 2. The rotation of the winding roller provides tension, further thinning the polyester filaments. The tension adjusting device 1 applies lateral pressure to the polyester filaments and detects the pressure value, adjusting the tension by increasing the depth of feed. The guiding device 2 changes the output position of the polyester filaments to facilitate their even winding onto the winding roller.

[0027] Furthermore, the tension adjustment device 1 includes a pressure application component 4, a pressure detection component 5, and an electric servo telescopic rod 6. A vertically downward-pointing electric servo telescopic rod 6 is provided on one side of the extrusion device. The pressure application component 4 is located at the output end of the electric servo telescopic rod 6, and the pressure detection component 5 is located near the pressure application component 4 and the electric servo telescopic rod 6. When the pressure application component 4 applies pressure to the polyester fiber filament, the electric servo telescopic rod 6 can control the depth of the pressure application component 4, thereby changing the pressure and thus altering the tension of the polyester filament.

[0028] Furthermore, the pressure application component 4 includes a pressure roller 7, a pressure roller frame 8, and a connecting rod 9. The pressure roller frame 8 is fixedly connected to the lower part of the connecting rod 9, and the pressure roller 7 is connected to the bearing inside the pressure roller frame 8. The lower end of the pressure roller 7 abuts against the polyester fiber filament. When the polyester filament is subjected to lateral pressure from the pressure roller 7, its tension along its original motion trajectory will be decomposed into a force perpendicular to the tangential direction of the pressure roller 7 and a force parallel to the tangential direction of the pressure roller 7. The new tension is a force parallel to the tangential direction of the pressure roller 7. Changing the motion trajectory of the polyester fiber filament can change the included angle value, thereby changing the tension value.

[0029] Furthermore, the pressure detection assembly 5 includes a structural sleeve 10, a top plate 12, a stop plate 13, a spring 14, and a pressure sensor 15. The structural sleeve 10 is fitted onto the side of the connecting rod 9 away from the pressure roller 7. A movable cavity 11 is provided inside the structural sleeve 10. A top plate 12 is provided at the end of the connecting rod 9 extending into the movable cavity 11. A stop plate 13, corresponding to the top plate 12, is provided inside the movable cavity 11. A spring 14 is provided between the stop plates 13. A pressure sensor 15 is provided on the side of the stop plate 13 away from the spring 14. The forces are mutual; the polyester fiber filaments are subjected to pressure from the pressure roller 7, and the pressure roller 7 is simultaneously subjected to a reverse thrust. The pressure sensor 15 detects the magnitude of this force, and by converting it using trigonometric functions, the tension value of the polyester fiber filaments can be obtained, thus providing a basis for controlling the extension amount of the electric servo telescopic rod 6.

[0030] Furthermore, the guiding device 2 includes a guide wheel frame 16, a first guide wheel 17, and a second guide wheel 18. The first guide wheel 17 is connected to the guide wheel frame 16 by a bearing. The second guide wheel 18 is located on the side of the first guide wheel 17 away from the pressure wheel 7. The second guide wheel 18 is connected to the guide wheel frame 16 by a bearing. The first guide wheel 17 is at a higher horizontal height than the second guide wheel 18. Both the first guide wheel 17 and the second guide wheel 18 are at a higher horizontal height than the pressure wheel 7. The upper end of the first guide wheel 17 abuts against the polyester fiber filaments, and the lower end of the second guide wheel 18 abuts against the polyester fiber filaments.

[0031] Furthermore, the guide device motion component 3 includes a slide rail 19, a slider 20, a lead screw 21, two sets of lead screw fixing blocks 22, and a servo motor 23. The slider 20 is slidably engaged on the slide rail 19, and the guide wheel frame 16 is fixedly connected to the slider 20. Lead screw fixing blocks 22 are provided on both sides of the slide rail 19, and the lead screw 21 is provided between the two sets of lead screw fixing blocks 22. The slider 20 is provided with an internal threaded hole corresponding to the lead screw 21, and the slider 20 is threadedly connected to the lead screw 21. The servo motor 23 is fixedly installed on the side of the lead screw fixing block 22 away from the lead screw 21, and the servo motor 23 is coaxially connected to the lead screw 21. Servo motor 23 provides power to lead screw 21. The rotation of lead screw 21 enables slider 20 to move along slide rail 19. Slider 20 drives guide device 2 on it to reciprocate, which can make polyester fiber filaments on take-up roller evenly wound. Compared with the traditional method, this method can make take-up roller longer, can wind more polyester fiber filaments, and can reduce take-up roller replacement work.

[0056] Working Principle: The stable polyester filament conveying and drawing equipment is a key piece of equipment in the production of polyester filaments. Its operation is closely integrated, with each component working in concert to ensure efficient and stable production of high-quality polyester fiber filaments. At the beginning of production, raw materials are fed into a high-temperature, high-pressure polymerization reactor. Under specific process conditions, a series of complex chemical reactions form polyester raw materials. The polyester raw materials are then output to the extrusion unit. Inside the extrusion unit, heating elements heat the polyester raw materials to a molten state, giving them good fluidity so they can be smoothly extruded from the extrusion nozzles below the extrusion unit, thus forming filamentous polyester. After being extruded, the filamentous polyester immediately enters the key adjustment stage of the equipment. First, the polyester filaments pass through the tension adjustment device 1. The electric servo telescopic rod 6 in this device is installed on one side of the extrusion unit, and its output end is connected to the pressure application component 4. The pressure roller 7 in the pressure application component 4 is connected to the electric servo telescopic rod 6 through the pressure roller frame 8 and the connecting rod 9. When the polyester filaments pass under the pressure roller 7, the pressure roller 7 applies lateral pressure. During this process, the pressure detection component 5 plays a crucial role. The structural sleeve 10 in the pressure detection assembly 5 is fitted onto the side of the connecting rod 9 facing away from the pressure roller 7, and has a movable cavity 11 inside. A top plate 12 is installed at the end of the connecting rod 9 extending into the movable cavity, and a corresponding abutment plate 13 is disposed within the movable cavity. The two are connected by a spring 14. A pressure sensor 15 is installed on the side of the abutment plate 13 facing away from the spring 14. Since forces are reciprocal, when the pressure roller 7 applies pressure to the polyester fiber filament, the pressure roller 7 also experiences a reverse thrust, which is transmitted to the pressure sensor 15. After detecting the force value, the pressure sensor 15 converts the detected force value into the tension value of the polyester fiber filament according to trigonometric relationships. The system automatically adjusts the extension of the electric servo telescopic rod 6 based on this tension value, thereby changing the pressure of the pressure roller 7 on the polyester filament and achieving precise control of the tension on the polyester filament. By maintaining constant tension, the produced polyester fiber filament is ensured to be of uniform thickness, and the filament is prevented from breaking due to excessive tension. After passing through the tension adjusting device 1, the polyester filament continues to the guiding device 2. The guiding device 2 consists of a guide wheel frame 16, a first guide wheel 17, and a second guide wheel 18. The first guide wheel 17 and the second guide wheel 18 are respectively mounted on the guide wheel frame 16 via bearings, and the horizontal height of the first guide wheel 17 is higher than that of the second guide wheel 18. Both of their horizontal heights are higher than that of the pressure roller 7. The upper end of the first guide wheel 17 abuts against the polyester fiber filament, and the lower end of the second guide wheel 18 abuts against the polyester fiber filament. In this way, the output position of the polyester filament is changed, preparing it for even winding onto the take-up roller. The guiding device motion assembly 3 below the guiding device 2 further ensures the uniformity of the polyester filament winding. The guiding device motion assembly 3 includes a slide rail 19, a slider 20, a lead screw 21, two sets of lead screw fixing blocks 22, and a servo motor 23.A slider 20 is slidably connected to the slide rail 19, and the guide wheel frame 16 is fixedly connected to the slider 20. A lead screw 21 is installed between the lead screw fixing blocks 22 on both sides of the slide rail 19. The slider 20 has an internal threaded hole corresponding to the lead screw 21, and the two are threadedly connected. A servo motor 23 is fixedly installed on the side of the lead screw fixing block 22 away from the lead screw 21, and the servo motor 23 is coaxially connected to the lead screw 21. When the servo motor 23 starts, it provides power to the lead screw 21, causing the lead screw 21 to rotate, which in turn drives the slider 20 to reciprocate along the slide rail 19. Since the guide device 2 is fixedly connected to the slider 20, the guide device 2 also reciprocates accordingly. In this way, the polyester fiber yarn can be evenly distributed when winding on the take-up roller. Compared with the traditional method, this method allows the take-up roller to be set longer, thereby winding more polyester fiber yarn, reducing the take-up roller replacement operation, and improving production efficiency. Throughout the production process, the take-up rollers rotate continuously, providing tension to the polyester filaments and further thinning them until the production of colored polyester filaments is complete. The stable polyester colored filament conveying and drawing equipment, through the coordinated work of its components, achieves precise control of the polyester fiber tension and uniform guidance during the winding process, ensuring stable equipment operation and high-quality product output.
