Description

Technical Field

[0001] This utility model relates to the field of yarn rewinding machine technology, specifically to an adaptive guiding structure for yarn rewinding machines suitable for polyester yarns of different diameters. Background Technology

[0002] In the ongoing innovation of the textile industry, consumers' demands for the quality, functionality, and diversity of textiles are increasing daily. This prompts textile companies to continuously enrich their product lines and develop various new fabrics. Polyester yarn, with its excellent physical properties, is widely used in many new fabrics. Different textile product designs range from extremely fine polyester yarns with low denier numbers used in high-end silk-textured fabrics to coarse polyester yarns used in industrial canvas and other products, with a wide range of yarn diameters. Rewinding, as a key link in the polyester yarn processing flow that connects raw materials with subsequent textile processes, directly affects the quality and production efficiency of the final textiles. This urgently requires rewinding equipment that can flexibly adapt to polyester yarns of various diameters.

[0003] Traditional polyester rewinding machines are equipped with guide structures that are mostly of fixed specifications or only support limited adjustments. While they can barely maintain production when dealing with polyester filament rewinding tasks of a single or a few diameters, their drawbacks become glaringly apparent when multiple diameters of polyester filament are used alternately. When switching to different diameter polyester filaments, operators need to manually replace guide components, such as guide sleeves with different apertures or guide plates of specific widths. The operation is complicated and time-consuming. Moreover, manual adjustment is prone to insufficient accuracy due to differences in operator experience and fatigue. This can cause the polyester filament to lose its stable and consistent path during rewinding, resulting in tangled and uneven tension, increasing the risk of filament breakage, and affecting production efficiency and product quality.

[0004] In conclusion, given the trend of product diversification in the textile industry, it is imperative to develop an adaptive guiding structure for spinning machines suitable for polyester yarns of different diameters. This will provide strong support for textile enterprises to quickly respond to market demands and launch more innovative products, and is of great significance to promoting the technological upgrading and sustainable development of the entire textile industry.

[0023] Furthermore, one end of the screw 7 is connected to the output end of the rotary motor 4 through the interior of the guide seat 2, and a single-phase rotating shaft 9 is installed on one side of the outer end of the screw 7.

[0024] Furthermore, the adaptive component 5 includes an arc plate 11, a limiting spring 12, auxiliary balls 13, and a fixed frame 14. The lower surface of the fixed frame 14 is connected to the upper surface of the slider. Arc plates 11 are respectively arranged around the inside of the fixed frame 14. Several auxiliary balls 13 are arranged and installed on the inner surface of the arc plate 11. A limiting spring 12 is connected to the center of the outer surface of the arc plate 11. The other end of the limiting spring 12 is fixedly connected to the inner surface of the fixed frame 14.

[0025] Furthermore, a limiting groove is formed in the center of the front surface of the limiting seat 3. A screw 15 is set in the center of the limiting groove. A single-phase rotating shaft 17 is installed on one side of the outer end of the screw 15. A track 10 is movably sleeved in the center of the single-phase rotating shaft 17. The other end of the track 10 is correspondingly sleeved on the outer end of the single-phase rotating shaft 9. A slider 16 is threaded on the outer end of the screw 15. The front end of the slider 16 extends through the inside of the limiting groove to the outer end of the front end of the limiting seat 3 and is correspondingly connected to the lower end surface of the adjusting frame 6.

[0026] Furthermore, the adjustment frame 6 is configured as a U-shaped body, with a sliding groove respectively opened in the center of the opposite surface on the inner side of the adjustment frame 6. A screw rod 18 is respectively installed inside the sliding groove. The upper end of the screw rod 18 extends through the upper end of the inner wall of the sliding groove to the upper outer end of the adjustment frame 6, and a rotating knob 19 is installed thereon. A mounting frame 20 is provided in the center of the inner side of the adjustment frame 6.

[0027] Furthermore, movable blocks are connected to the outer two sides of the mounting frame 20 respectively. The outer ends of the movable blocks are slidably sleeved inside the slide groove. Threaded holes are opened in the center of the movable blocks respectively. The screw rod 18 is threadedly sleeved inside the threaded holes. Guide roller shafts 21 are installed on the upper and lower sides inside the mounting frame 20.

[0028] Base Plate 1: As the basic support component of the entire self-adaptive guide structure of the wire rewinding machine, Base Plate 1 plays a crucial role in stabilizing the installation of the equipment. The mounting holes around its outer perimeter allow the entire guide structure to be firmly fixed to the worktable using bolts or other connectors, ensuring that the equipment will not shift due to vibration or other factors during operation, and providing a solid guarantee for the stable operation of other components.

[0029] Guide seat 2: Installed on the upper surface of the base plate 1, guide seat 2 serves the dual important functions of providing a mounting base and guidance for other components. A guide groove is provided in the center of its upper surface, and a screw 7 is placed in the center of this groove, with guide rods 8 symmetrically installed on both sides. Guide seat 2 provides a stable spatial structure for the operation of screw 7 and guide rods 8, ensuring the linearity and stability of their movement.

[0030] Limiting seat 3: Connected to the front end surface of guide seat 2, with a dedicated limiting groove in the center of its front end surface. Screw 15 is installed in the center of the groove, and a single-phase rotating shaft 17 is equipped on one side of its outer end. Limiting seat 3 effectively constrains the movement range of screw 15 and its associated slider 16 through internal means, ensuring that the entire guide structure operates within a safe and controllable range.

[0031] Rotary motor 4: Installed on one side of the outer end of guide seat 2, rotary motor 4 is one of the power sources of the entire guide structure. Its output end is tightly connected to one end of screw 7. When rotary motor 4 is powered on and started, the rotational motion of the motor can be transmitted to screw 7, driving screw 7 to rotate, thereby providing power support for subsequent components that rely on the rotation of screw 7 to achieve linear motion.

[0032] Adaptive component 5: Located at the upper end of guide seat 2, the lower end of fixed frame 14 and slider are located in the guide groove of guide seat, and are stably connected at the upper end by screw drive. Arc-shaped plates 11 are evenly distributed around the inside of fixed frame 14. Several auxiliary balls 13 are arranged and installed on the inner side of the arc-shaped plates 11, and the outer center is connected to the inner side of fixed frame 14 by a limiting spring 12. Adaptive component 5 can adjust the internal space according to the diameter of the polyester yarn passing through, using the adaptive opening and closing of the arc-shaped plates 11 under the action of the limiting spring 12, to adapt to polyester yarns of different diameters, while the auxiliary balls 13 reduce friction when the polyester yarn passes through.

[0033] Adjusting frame 6: Located at the front end of the limiting seat 3, the adjusting frame 6 has a U-shaped structure. Slide grooves are respectively formed in the center of opposite inner surfaces, and screw 18 is installed in each groove. The upper end of screw 18 extends to the outer end of the upper part of the adjusting frame 6 and is fitted with a rotating knob 19. The front end of the adjusting frame 6 is connected to the slider 16 by screw 2. Rotation of screw 2 15 drives the adjusting frame 6 to move back and forth. Simultaneously, rotating the rotating knob 19 allows screw 18 to drive the mounting frame 20 to move up and down within the slide groove, thereby flexibly adjusting the position of the guide roller shaft 21 to meet the requirements of rewinding polyester filaments of different diameters.

[0034] Screw 7: Located in the center of the guide groove of guide seat 2, one end is connected to the output end of rotary motor 4, and a single-phase rotating shaft 9 is installed on one side of the outer end. When rotary motor 4 drives screw 7 to rotate, the slider threadedly connected to it is restricted to linear movement by guide rod 8. Therefore, the rotational motion of screw 7 is converted into linear movement of slider in guide groove, which in turn drives the adaptive component 5 connected to it to move, thereby adjusting the guide position of polyester filament.

[0035] Guide rod 8: Symmetrically installed on both sides of the outer end of screw 7 within the guide groove of guide seat 2. Guide rod 8 mainly serves to stabilize the movement direction of the slider. When the slider moves in a straight line along screw 7, guide rod 8 constrains the slider to move only in the straight direction defined by the guide groove, preventing the slider from deviating or wobbling due to the rotation of screw 7, ensuring smooth movement of the adaptive component 5, and guiding the polyester filament.

[0036] Single-phase rotating shaft 9: Installed on one side of the outer end of screw 7, single-phase rotating shaft 9 is used for power transmission with other components. By cooperating with track 10, it transmits the rotational power of screw 7 to screw 15, realizing the synchronous rotation of the two screws, thereby coordinating the movement of related components of guide seat 2 and limit seat 3.

[0037] Track 10: One end of track 10 is sleeved on the outer end of single-phase rotating shaft 9, and the other end is correspondingly sleeved on the center of single-phase rotating shaft 17. Track 10 serves as a power transmission component, establishing a connection between single-phase rotating shaft 9 and single-phase rotating shaft 17, transmitting the power generated by the rotation of screw 7 to screw 15, ensuring that the two screws can rotate synchronously, so that the movement of the guide seat 2 and the limiting seat 3 and related components cooperate to complete the guiding work of the polyester filament.

[0038] Arc-shaped plates 11 are distributed around the inside of the self-adaptive component 5 fixing frame 14. When polyester filaments of different diameters pass through the self-adaptive component 5, the polyester filaments will exert radial pressure on the arc-shaped plates 11. If the polyester filament diameter is thicker, the pressure causes the arc-shaped plates 11 to expand outward against the elastic force of the limiting spring 12; if the filament diameter is thinner, the limiting spring 12 causes the arc-shaped plates 11 to contract inward. Multiple arc-shaped plates 11 work together to adaptively adjust the space suitable for polyester filaments of different diameters to pass through.

[0039] Limiting spring 12: Connected between the center of the outer end surface of the arc-shaped plate 11 and the perimeter of the inner surface of the fixed frame 14, the limiting spring 12 provides restoring force to the arc-shaped plate 11. Under the action of polyester yarns of different diameters, the arc-shaped plate 11 can flexibly expand or contract under the elastic force of the limiting spring 12, realizing adaptive adjustment for polyester yarns of different diameters, and ensuring that the arc-shaped plate 11 returns to its initial position when no external force is applied, preparing for the next adaptive adjustment.

[0040] Auxiliary ball bearings 13: Installed on the inner surface of the arc-shaped plate 11, the main function of the auxiliary ball bearings 13 is to reduce the friction between the polyester filament and the arc-shaped plate 11 when passing through the adaptive component 5. This not only allows the polyester filament to pass through more smoothly and improves the yarn rewinding efficiency, but also effectively reduces damage to the surface of the polyester filament, ensuring the stability and efficiency of the yarn rewinding process and ensuring that the quality of the polyester filament is not affected.

[0041] Fixed frame 14: The lower surface of the fixed frame 14 is located in the guide groove of the guide seat and the upper surface is stably connected by the screw. It provides an installation frame for other components of the adaptive assembly 5, such as the arc plate 11, the limit spring 12, and the auxiliary ball 13. Under the drive of the slider, the adaptive assembly 5 can move on the upper end of the guide seat 2, ensuring that the entire adaptive assembly 5 can accurately guide the polyester yarn.

[0042] Screw 2 15: Located in the center of the limiting groove on the front surface of the limiting seat 3, screw 2 15 rotates synchronously with screw 1 7 via track 10. When screw 2 15 rotates, the slider 16, which is threadedly connected to it, moves linearly within the limiting groove, thereby driving the adjusting frame 6 connected to the front end of slider 16 to move back and forth at the front end of the limiting seat 3, thus adjusting the position of the adjusting frame 6 to accommodate the rewinding requirements of polyester filaments of different diameters.

[0043] Slider 16: Slider 16 is threaded onto the outer end of screw 15, and its front end extends through a limiting groove to the outer end of the front end of the limiting seat 3, connecting with the lower surface of the adjusting frame 6. When screw 15 rotates, slider 16 converts the rotational motion of screw 15 into its own linear motion within the limiting groove, thereby driving the adjusting frame 6 to move. It is a key transmission component for realizing the position adjustment of the adjusting frame 6.

[0044] Single-phase rotating shaft 2 17: Installed on one side of the front end of the limit seat 3, single-phase rotating shaft 2 17 is connected to single-phase rotating shaft 1 9 through track 10, receives rotational power from screw 1 7 and transmits it to screw 2 15, ensuring that screw 2 15 rotates synchronously with screw 1 7, coordinating the movement of guide seat 2 and related components of limit seat 3, and ensuring the coordinated operation of the entire guide structure.

[0045] Screw 3 18: Installed in a groove in the center of the inner surface of the adjusting frame 6. The upper end of screw 3 18 extends to the outer end of the upper end of the adjusting frame 6 and is fitted with a rotary knob 19. Rotating the rotary knob 19 causes screw 3 18 to rotate. Since the mounting frame 20 is threadedly connected to screw 3 18 via a moving block and is restricted by the groove, the rotation of screw 3 18 drives the mounting frame 20 to move up and down within the adjusting frame 6, achieving precise adjustment of the position of the mounting frame 20, thereby adjusting the height of the guide roller shaft 21 to accommodate different diameter polyester yarns.

[0046] Rotary knob 19: Installed on the upper end of screw 3 18 extending to the outer end of the upper part of the adjusting frame 6, the operator can manually rotate the rotary knob 19 to easily control the rotation of screw 3 18. By rotating the rotary knob 19, the vertical position of the mounting frame 20 within the adjusting frame 6 can be adjusted, thereby flexibly changing the height of the guide roller shaft 21 to meet the guiding requirements of polyester filaments of different diameters during the rewinding process. The operation is simple and intuitive.

[0047] Mounting frame 20: The outer ends of the mounting frame 20 are connected to the sliding groove of the adjusting frame 6 via movable blocks on both sides. The movable blocks have a threaded hole in the center that is threaded to the screw 18. Inside the mounting frame 20, guide rollers 21 are installed vertically. Driven by the rotation of the screw 18, the mounting frame 20 can move up and down within the adjusting frame 6, thereby adjusting the position of the guide rollers 21 and guiding polyester filaments of different diameters to ensure that the polyester filaments maintain the correct path during the rewinding process.

[0048] Guide roller 21: Installed inside the mounting frame 20 at the upper and lower positions. The guide roller 21 is in direct contact with the polyester yarn. With the coordinated action of the adjusting frame 6 moving back and forth and the mounting frame 20 moving up and down, the guide roller 21 can flexibly adjust its position to provide guidance for polyester yarns of different diameters during the winding process, ensuring that the polyester yarn can be accurately and stably wound on the corresponding spool and guaranteeing the winding quality.

[0049] Instructions for use

[0050] The base plate 1 is used for the installation and fixing of the equipment. It can be firmly installed on the workbench through the mounting holes around the perimeter. The guide seat 2 is installed on the upper end of the base plate 1 to provide the installation foundation and guidance function for other components. The limit seat 3 is connected to the front end of the guide seat 2 to limit the movement of related components. The rotary motor 4 is installed on one side of the outer end of the guide seat 2 to provide power for the rotation of the screw 7. The adaptive component 5 is located on the upper end of the guide seat 2 and can be adaptively adjusted according to the diameter of the polyester yarn. The adjustment frame 6 is set at the front end of the limit seat 3 to further adjust the guide structure to adapt to different working requirements. The fixed frame 14 is connected to the upper end of the slider, and the slider can move in the guide groove of the guide seat 2 as the screw 7 rotates. When polyester yarns of different diameters pass through the adaptive component 5, the polyester yarns will generate radial pressure on the arc plate 11. If the polyester yarn diameter is thicker, the pressure will cause the arc plate 11 to overcome the elastic force of the limit spring 12 and expand outward. Multiple arc plates 11 work together to adaptively adjust the space suitable for the passage of thicker polyester yarns.If the wire diameter is thin, the limiting spring 12 will cause the arc plate 11 to contract inward, reducing the internal space. The auxiliary ball bearing 13 is installed on the inner surface of the arc plate 11, which can reduce the friction between the polyester filament and the arc plate 11 when passing through, allowing the polyester filament to pass through more smoothly. At the same time, it can also reduce damage to the surface of the polyester filament, ensuring the stability and efficiency of the rewinding process. A guide groove is opened in the center of the upper surface of the guide seat 2, and a screw 7 is set in the center of the groove. Guide rods 8 are installed on both sides. One end of the screw 7 is connected to the output end of the rotary motor 4. When the rotary motor 4 is started, it drives the screw 7 to rotate. Since the slider is threaded on the screw 7 and is also subjected to The guide rod 8 restricts its movement to a straight line along the guide groove. Therefore, the rotation of the screw 7 is converted into the linear movement of the slider within the guide groove. The movement of the slider then drives the adaptive component 5 connected to its upper end to move on the upper end of the guide seat 2. During this process, the guide rod 8 stabilizes the direction of the slider's movement, ensuring the smooth movement of the adaptive component 5 and enabling it to effectively guide the polyester filament. In addition, a single-phase rotating shaft 9 is installed on one side of the outer end of the screw 7 for power transmission or collaborative work with other components. A limit groove is formed in the center of the front surface of the limit seat 3, and a screw 15 is set in the center of the groove. A single-phase rotating shaft is installed on one side of the outer end. Single-phase rotating shaft 17 is connected to single-phase rotating shaft 9 via track 10. When the rotary motor 4 drives screw 7 to rotate, screw 15 can rotate synchronously through the transmission between single-phase rotating shaft 9 and track 10. Slider 16 is threaded onto the outer end of screw 15. The rotation of screw 15 causes slider 16 to move linearly within the limiting groove. The front end of slider 16 is connected to adjusting frame 6, thereby enabling the adjusting frame 6 to move back and forth at the front end of limiting seat 3. Adjusting frame 6 is U-shaped, with grooves opened in the center of opposite inner surfaces. Screw 18 is installed in the grooves, with the upper end of screw 18 extending to the outer end of the upper part of adjusting frame 6 and mounted thereon. The device includes a rotating knob 19 and a mounting frame 20 connected to a slide groove via a movable block. A threaded hole in the center of the movable block is threadedly connected to a screw rod 18. When the rotating knob 19 is rotated, the screw rod 18 rotates. Because the movable block is restricted to linear movement by the slide groove, the rotation of the screw rod 18 drives the mounting frame 20 to move up and down within the adjusting frame 6. A guide roller shaft 21 is installed inside the mounting frame 20. By moving the adjusting frame 6 back and forth and the mounting frame 20 up and down, the position of the guide roller shaft 21 can be flexibly adjusted to meet the guiding requirements of polyester yarns of different diameters during the winding process, ensuring that the polyester yarns can be accurately and stably wound onto the corresponding spools.
