[0030] Structure description

[0031] Base 1:

[0032] The whole winding device is made of strong metal material (such as steel) with enough strength and stability to support the weight of the whole winding device and various forces generated during operation. The shape is usually rectangular, and the flat design ensures smooth installation of each part. The winding shaft mounting bracket 2 on both sides of the top is firmly fixed by welding or bolt connection to ensure that the winding shaft 4 does not shake or deviate during high-speed rotation. The teeth 10 on one side of the base 1 are precisely machined, with uniform tooth shape and spacing, and can accurately transmit power when meshing with the gear 9, making the lateral movement of the loading platform 7 stable and accurate with minimal error. The inner wall of the rectangular slide 5 is smooth and treated with anti-rust to reduce friction when the sliding block 6 slides and prevent rust from affecting the sliding performance. The depth and width are designed reasonably to ensure that the sliding block 6 does not fall out and provide enough space and freedom for the movement of the loading platform 7.

[0033] Winding shaft mounting bracket 2:

[0034] Made of high-strength alloy material with good bending and torsional resistance. Its structure is designed as a column or frame with moderate height, which is convenient for the installation and disassembly of the winding shaft 4. The inner side of the mounting bracket is provided with a bearing seat, which uses high-precision ball bearings to effectively reduce the friction resistance when the winding shaft 4 rotates, reduce energy loss and prolong the service life of the bearing. The cooperation tolerance between the bearing seat and the winding shaft 4 is strictly controlled to ensure that the winding shaft 4 can stably rotate between the mounting brackets with minimal radial runout and axial movement, thereby ensuring the uniformity and stability of the polyester filament during winding.

[0035] Winding shaft drive motor 3:

[0036] Generally, a three-phase asynchronous motor is selected, which has high power and torque output to meet the requirements of different specifications of polyester filament winding for speed and tension. The motor housing is made of aluminum alloy material with good heat dissipation performance, and the surface is designed with heat dissipation fins to effectively dissipate the heat generated during motor operation and prevent overheating damage. The connection between the output shaft of the motor and the rotating connection block 13 adopts key connection to ensure the reliability and stability of power transmission. The motor is equipped with a speed regulator and an overload protection device. The speed regulator can accurately adjust the speed of the winding shaft 4 according to the production process requirements, so that the winding speed of the polyester filament can be flexibly controlled; the overload protection device automatically cuts off the power supply when the motor load is too large to protect the motor and the whole winding device from damage.

[0037] Winding shaft 4:

[0038] Most are hollow cylindrical structures, usually made of lightweight and high-strength aluminum alloy or carbon fiber composite materials to reduce their own weight and reduce the moment of inertia, facilitating rapid start and stop. Its surface is finely polished and polished to allow the polyester yarn to be tightly fitted and not to slip when winding. The length of the winding shaft 4 is determined according to the actual production needs, and can adapt to the winding of polyester yarn of different widths. The rectangular clamping protrusion 17 at the end is made of precision casting or machining, with high dimensional accuracy, and is tightly matched with the rectangular slot 16 on the fixed block 15, ensuring firm connection while facilitating quick installation and removal of the winding shaft 4. During the winding process, the balance performance of the winding shaft 4 is crucial, and balance blocks may be installed inside or dynamically balanced to reduce vibration during high-speed rotation and ensure the quality of polyester yarn winding.

[0039] Rectangular slide 5:

[0040] It is a long groove structure on the base 1 by machining (such as milling, planing, etc.). Its length matches the lateral movement stroke of the bearing table 7, and is generally slightly longer than the maximum movement distance of the bearing table 7 to ensure stable support of the bearing table 7 throughout the movement range. The width and depth tolerance of the rectangular slide 5 is controlled within a very small range, forming a tight sliding fit with the slider 6. The bottom and sides may be equipped with wear-resistant guide rail materials (such as polytetrafluoroethylene slider or bronze guide rail) to further reduce the friction coefficient between the slider 6 and the rectangular slide 5, improve the smoothness and accuracy of the bearing table 7 movement, reduce heat and wear caused by friction, and prolong the service life of the device.

[0041] Slider 6:

[0042] Made of wear-resistant engineering plastics (such as nylon) or metal materials (such as aluminum alloy), the shape is adapted to the rectangular slide 5, and is in the shape of a cuboid. The surface of the slider 6 is smooth, and the contact area with the rectangular slide 5 is large to evenly distribute the weight of the bearing table 7 and reduce the pressure per unit area. Seals (such as rubber seals) may be installed on both sides of the slider 6 to prevent dust, debris, etc. from entering the rectangular slide 5, affecting the sliding performance and service life of the slider 6. The connection between the slider 6 and the bearing table 7 is firm and reliable, which can be achieved by welding, bolt connection or one-piece forming, etc. to ensure that the slider 6 can always maintain good contact and stable cooperation with the rectangular slide 5 during the movement of the bearing table 7.

[0043] Bearing table 7:

[0044] The base 1 is made of metal plate welding or casting, with sufficient rigidity and strength to support the weight of the walking motor 8, guide shaft support 11 and other components and the force generated during operation. Its shape is usually rectangular flat, and the sliders 6 on the bottom are evenly distributed in appropriate positions to ensure that the bearing table 7 moves smoothly and evenly in the transverse direction. The top of the bearing table 7 is provided with a mounting seat for fixing the walking motor 8, and the structure design of the mounting seat can ensure the installation accuracy and stability of the motor, reducing the vibration transmission to the bearing table 7 during operation. The side or bottom of the bearing table 7 may be designed with reinforcing ribs to further improve its structural strength and prevent deformation or damage during long-term use.

[0045] Walking motor 8:

[0046] Mostly DC speed reducer motor or stepper motor, with good speed regulation performance and precise position control ability. DC speed reducer motor can realize stepless speed regulation by changing input voltage, and stepper motor can accurately control the angle and step number of rotation, so as to realize the precise transverse movement of the bearing table 7. The motor body adopts sealed design to prevent dust, fibers and other impurities from entering the motor interior and affecting its performance. The connection between the output shaft of the motor and the gear 9 adopts shaft coupling or key connection to ensure the efficiency and accuracy of power transmission. The walking motor 8 is equipped with a controller, which can control the start-stop, speed and direction of the motor according to the preset program or external signals (such as sensor feedback), realizing the automatic uniform winding control in the polyester filament winding process.

[0047] Gear 9:

[0048] The material is generally high-strength alloy steel, which is treated by quenching and tempering and other heat treatment processes to improve its surface hardness and wear resistance. The tooth shape of the gear 9 adopts involute tooth shape, with good transmission performance and stability. Its modulus and tooth number are designed and calculated according to the moving speed of the bearing table 7 and the required torque, and are accurately matched with the teeth 10 on the base 1. The gear 9 is closely connected with the output shaft of the walking motor 8, with high concentricity, and can rotate smoothly under the drive of the motor, and accurately transmit power to the bearing table 7, so that the bearing table 7 moves transversely on the base 1 according to the predetermined speed and trajectory. In order to reduce the noise and vibration during gear transmission, the gear 9 may be subjected to tooth surface modification or adopt special lubrication method (such as oil injection lubrication or grease lubrication).

[0049] Teeth 10:

[0050] The teeth 10 that match the gear 9 are evenly distributed on the base 1, and the tooth surface is precisely machined and heat treated, with high hardness and wear resistance. The tooth shape, module and pitch of the teeth 10 are completely consistent with the gear 9, ensuring that the two can be closely matched during meshing without gap or interference. The length and height of the teeth 10 are designed reasonably, which can ensure sufficient meshing length to transmit stable power, and also will not affect the stability of the moving of the bearing table 7 due to being too high. Protective devices (such as protective covers) can be provided around the teeth 10 to prevent debris from entering the meshing area of the teeth, damaging the gear and teeth, and also protecting the safety of the operators.

[0051] The guide shaft support 11:

[0052] It is made of metal material (such as stainless steel) and has good rigidity and corrosion resistance. Its structure is columnar or L-shaped, and the height and position can be adjusted according to the diameter of the guide shaft 12 and the winding height of the polyester yarn. The top of the guide shaft support 11 is provided with a bearing seat, which adopts high-precision deep groove ball bearing or cylindrical roller bearing, for installing the guide shaft 12, so that the guide shaft 12 can rotate flexibly, reducing the friction resistance and wear of the polyester yarn during guiding. The matching precision between the bearing seat and the guide shaft 12 is high, and sealing devices are installed to prevent dust, fibers and other impurities from entering the bearing interior, affecting the service life of the bearing and the rotating performance of the guide shaft 12. The distance between the two guide shaft supports 11 is adjusted according to the width of the polyester yarn and the winding requirements, to ensure that the polyester yarn can pass smoothly on the guide shaft 12 without deviation.

[0053] The guide shaft 12:

[0054] It is usually made of stainless steel or ceramic material, with good wear resistance, corrosion resistance and smooth surface. The diameter of the guide shaft 12 is selected according to the thickness and strength of the polyester yarn, and is generally several times larger than the diameter of the polyester yarn, to ensure the stability and smoothness of the polyester yarn during guiding. Its surface is finely polished, with very low roughness, which can effectively reduce the friction coefficient between the polyester yarn and the guide shaft 12. The two ends of the guide shaft 12 are installed on the guide shaft supports 11 through bearings, which can rotate freely and flexibly. When the bearing table 7 moves laterally, the guide shaft 12 moves with it and guides the polyester yarn to be evenly wound on the winding shaft 4, avoiding the phenomenon of crossing, overlapping or uneven winding of the polyester yarn.

[0055] The rotating connecting block 13:

[0056] Made of high-strength alloy steel, the block is fixedly connected to the output shaft of the take-up shaft drive motor 3 on one side, with a robust and reliable connection method, such as a key connection and tightening with a nut at the shaft end. A circular groove on the other side is used to install the spring 14 and the fixing block 15. The depth and diameter of the groove require high precision to ensure accurate installation of the spring 14 and the fixing block 15 without loosening or shifting during operation. The surface of the rotating connecting block 13 is ground, resulting in low roughness and good contact with the end of the take-up shaft 4, reducing energy loss and vibration during power transmission. Its internal structure is rationally designed, taking into account the compression and rebound space of the spring 14 and the movement trajectory of the fixing block 15, ensuring smooth and coordinated operation of all components during the installation and disassembly of the take-up shaft 4.

[0057] Spring 14:

[0058] Made of high-quality spring steel wire, it possesses suitable elastic modulus and fatigue life. The specifications of spring 14 (such as wire diameter, outer diameter, length, and number of coils) are designed and calculated based on the connection requirements and required preload of the winding shaft 4. Under normal conditions, spring 14 is in a certain pre-compression state, providing sufficient elasticity to the fixing block 15, ensuring a tight engagement between the rectangular groove 16 and the rectangular locking protrusion 17, guaranteeing the connection stability of the winding shaft 4 during operation. The surface of spring 14 is treated with rust prevention to prevent rust from affecting its elastic properties and service life. During long-term use, the performance of spring 14 may change, therefore regular inspection and replacement are necessary to ensure the connection reliability of the winding shaft 4.

[0059] Fixed block 15:

[0060] Made of metal (such as carbon steel), the fixed block 15 is block-shaped. One end is inserted into the circular groove of the rotating connecting block 13 and fixedly connected to the spring 14. The connection can be made by welding or riveting to ensure a firm connection. The rectangular groove 16 on the side of the fixed block 15 opposite to the rotating connecting block 13 has high dimensional accuracy and fits tightly with the rectangular snap-fit ​​protrusion 17 at the end of the take-up shaft 4. The tolerance is controlled within a very small range to ensure the reliability and stability of the connection. The surface of the fixed block 15 is polished to reduce the roughness and friction between it and the rectangular snap-fit ​​protrusion 17. When disassembling the take-up shaft 4, pressing the fixed block 15 overcomes the elastic force of the spring 14, causing the rectangular groove 16 to disengage from the rectangular snap-fit ​​protrusion 17, making the operation convenient and quick.

[0061] Rectangular slot 16:

[0062] The rectangular slot 16, formed on the fixing block 15, has a depth and width that matches the rectangular snap-fit ​​protrusion 17 at the end of the take-up shaft 4. Its inner surface is smooth, without burrs or sharp edges, allowing it to fit tightly against the rectangular snap-fit ​​protrusion 17 during engagement, ensuring that the take-up shaft 4 does not experience axial movement or radial wobble. The rectangular slot 16 requires high machining precision and is manufactured using processes such as precision milling or wire cutting to ensure that its dimensional and shape tolerances meet design requirements. Chamfers or rounded corners may be designed at the edges of the rectangular slot 16 to facilitate the smooth entry and exit of the rectangular snap-fit ​​protrusion 17, reducing wear and damage to components during installation and disassembly.

[0063] Rectangular snap-fit ​​protrusion 17:

[0064] The rectangular snap-fit ​​protrusion 17 located at the end of the take-up shaft 4 is precision cast or machined, and its material is the same as or compatible with that of the take-up shaft 4. It is rectangular in shape, with high dimensional accuracy and strict tolerance control in length, width, and height, forming a tight snap-fit ​​with the rectangular groove 16 on the fixing block 15. The surface of the rectangular snap-fit ​​protrusion 17 is polished, resulting in low roughness and reducing frictional resistance with the rectangular groove 16. During the installation of the take-up shaft 4, the rectangular snap-fit ​​protrusion 17 is aligned with the rectangular groove 16. After releasing the fixing block 15, the rectangular snap-fit ​​protrusion 17 smoothly snaps into the rectangular groove 16 under the action of the spring 14, completing the installation connection of the take-up shaft 4. During disassembly, pressing the fixing block 15 disengages the rectangular groove 16 from the rectangular snap-fit ​​protrusion 17, allowing the take-up shaft 4 to be removed. The operation is simple and convenient, and the connection is reliable.

[0065] Working principle: When winding polyester yarn, the polyester yarn is guided through the polyester yarn winding guide structure and finally wound onto the winding shaft 4. As the winding shaft drive motor 3 starts, it drives the winding shaft 4 to rotate, and then winds the polyester yarn. During the winding process, the polyester yarn winding guide structure moves laterally, which drives the guided yarn to move laterally, so that the polyester yarn can be evenly wound onto the winding shaft 4, achieving uniform winding.
