[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 4As shown, an adjustable winding device according to an embodiment of the present invention includes a base plate 1; a first vertical plate 11 is fixedly connected to the top side wall of the base plate 1; a second vertical plate 12 is fixedly connected to the top side wall of the base plate 1; the first vertical plate 11 and the second vertical plate 12 are symmetrically arranged; a drive motor 13 is assembled in the middle of the side wall of the second vertical plate 12; an adjustment component is provided at the output end of the drive motor 13; a take-up roller 14 is provided outside the adjustment component; a material-taking component is provided in the middle of the side wall of the take-up roller 14; a guide component is provided between the first vertical plate 11 and the second vertical plate 12; a cleaning component is provided in the middle of the side wall of the base plate 1; the cleaning component is located between the guide component and the adjustment component; an unwinding roller 15 is rotatably connected between the first vertical plate 11 and the second vertical plate 12; the guide component is located between the unwinding roller 15 and the take-up roller 14; during operation, the operator puts the take-up roller 14 onto the adjustment component. Outside the section component, adjust the size of the adjusting component so that it supports the take-up roller 14 from the inside. Then, wind the polyester-cotton yarn around the side wall of the unwind roller 15, pull one end of the polyester-cotton yarn and wrap it around the bottom of the guide component, and then wind it around the material-taking component on the side wall of the take-up roller 14. At this time, the operator starts the drive motor 13, which drives the adjusting component to rotate, causing the adjusting component to rotate the take-up roller 14, and causing the take-up roller 14 to rotate synchronously with the material-taking component. At this time, the polyester-cotton yarn will be guided by the guide component to wind from the side wall of the unwind roller 15 onto the take-up roller 14. After the winding is completed, the operator uses the material-taking component to remove the polyester-cotton yarn from the take-up roller 14. During the winding process, the cleaning component will suck up the flying dust and other particles to prevent dust from adhering to the polyester-cotton yarn.

[0026] like Figures 1 to 3As shown, the adjustment assembly includes a first electric actuator 2; the first electric actuator 2 is fixed to the output end of the drive motor 13; the first electric actuator 2 rotates on the second upright plate 12; a second electric actuator 21 is rotatably connected to the middle of the side wall of the first upright plate 11; the second electric actuator 21 and the first electric actuator 2 are correspondingly arranged; both the output ends of the second electric actuator 21 and the first electric actuator 2 are equipped with movable rods 22; fixed seats 23 are rotatably connected to the middle of the side walls of the first upright plate 11 and the second upright plate 12; the fixed seats 23 and the first electric actuator 2 are fixedly connected; multiple adjustment plates 24 are slidably connected to the middle of the side walls of the fixed seats 23; the middle of the side walls of the adjustment plates 24 and the movable rods 22 are... Each component is fixed with a fixed plate 25; multiple support rods 26 are rotatably connected between opposing fixed plates 25; the take-up roller 14 is covered by multiple adjusting plates 24; when the operator covers the take-up roller 14 with the multiple adjusting plates 24, the first electric actuator 2 and the second electric actuator 21 are activated. At this time, the first electric actuator 2 and the second electric actuator 21 will drive the movable rod 22 to move, causing the movable rod 22 to pull the multiple support rods 26 on the side wall to rotate. When the support rods 26 rotate, they will pull the multiple adjusting plates 24 to slide along the side wall of the fixed seat 23. At this time, the multiple adjusting plates 24 will change their outward opening as the movable rod 22 moves. Adjust the distance by setting the adjusting plate 24 to a position that precisely supports the take-up roller 14, stop the first electric push rod 2 and the second electric push rod 21, and then start the drive motor 13. At this time, the drive motor 13 will drive the first electric push rod 2 to rotate, so that the first electric push rod 2 drives the second electric push rod 21, the movable rod 22, the fixed seat 23, the adjusting plate 24, the fixed plate 25, the support rod 26, the take-up roller 14, and the polyester-cotton yarn wound on the outside of the take-up roller 14 to rotate synchronously. At this time, the polyester-cotton yarn will be wound from the unwinding roller 15 onto the surface of the take-up roller 14. This step is achieved by setting the first electric push rod 2, the second electric push rod 21, the movable rod 22, the fixed seat 23, the adjusting plate 24, the fixed plate 25, the support rod 26, the take-up roller 14, and the polyester-cotton yarn wound on the outside of the take-up roller 14. The seat 23, adjusting plate 24, fixing plate 25, and support rod 26 can be quickly adjusted to a suitable diameter according to the specifications and winding requirements of the polyester-cotton yarn. This flexibility helps the production line to quickly adapt to the production of different batches or specifications of polyester-cotton yarn, improving overall production efficiency. By setting a support device that adapts to different diameters of the take-up roller 14, the take-up roller 14 can be fixed from the inside, so that the take-up roller 14 can maintain a more stable rotation state when winding the polyester-cotton yarn, reducing shaking or deviation caused by external factors. This helps to maintain uniform tension and arrangement of the yarn during the winding process, thereby improving the winding quality.

[0027] like Figure 1 and Figure 4As shown, the guide assembly includes a reciprocating motor 3; the reciprocating motor 3 is mounted on the side wall of the second vertical plate 12; a threaded rod 31 is fixedly connected to the output end of the reciprocating motor 3; the threaded rod 31 rotates between the first vertical plate 11 and the second vertical plate 12; a movable ring is slidably connected to the middle of the side wall of the threaded rod 31; a pulley 32 is rotatably connected to the middle of the side wall of the movable ring; during the process of the polyester-cotton yarn winding around the bottom of the pulley 32 and onto the side wall of the take-up roller 14, the operator starts the reciprocating motor 3, which drives the threaded rod 31 to rotate. When the threaded rod 31 rotates, the movable ring on its side wall will... Sliding along the threaded rod 31 causes the movable ring to drive the pulley 32 to move synchronously. When the polyester-cotton yarn moves at the bottom of the pulley 32, the pulley 32 will rotate on the movable ring. This step, by setting up the reciprocating motor 3, the threaded rod 31 and the pulley 32, can guide the polyester-cotton yarn to wind onto the take-up roller 14 according to a predetermined path and method, so that the polyester-cotton yarn is evenly distributed on the surface of the take-up roller 14, reducing the accumulation and unevenness of the polyester-cotton yarn on the take-up roller 14, making the yarn tighter and neater during the winding process, and further improving the winding efficiency and product quality.

[0028] like Figure 1 and Figure 4 As shown, the cleaning assembly includes a dust collection box 4; the dust collection box 4 is mounted on the side wall of the base plate 1; an exhaust pipe 41 is fixedly connected to the middle of the side wall of the dust collection box 4; multiple suction holes 42 are opened on the top side wall of the dust collection box 4; the dust collection box 4, the exhaust pipe 41, and the suction holes 42 are all hollow and interconnected; during operation, the operator connects the exhaust pipe 41 to the vacuum pump. Because the dust collection box 4, the exhaust pipe 41, and the suction holes 42 are interconnected, the vacuum pump will drive the dust and other particles generated during the winding process into the dust collection box 4 through airflow. This step, by setting up the dust collection box 4, the exhaust pipe 41, and the suction holes 42, can effectively remove dust, lint, and impurities generated during the winding of polyester-cotton yarn, reduce the impact of these pollutants on yarn quality, help reduce the defect rate and rework rate in subsequent processing, and thus further improve the overall product quality.

[0029] like Figure 1 and Figure 2 As shown, the material handling assembly includes an airbag 5; the airbag 5 is installed on the side wall of the take-up roller 14; a connecting tube 51 is fixed in the middle of the side wall of the airbag 5; both the airbag 5 and the connecting tube 51 are hollow and connected; both the airbag 5 and the connecting tube 51 are made of elastic material; after all the polyester-cotton yarn is wound on the side wall of the airbag 5, the operator opens the connecting tube 51 to release the gas inside the airbag 5, causing the airbag 5 to deflate and no longer press against the polyester-cotton yarn. At this time, the operator can easily remove the polyester-cotton yarn from the airbag 5. This step of setting up the airbag 5 and the connecting tube 51 only requires the air release operation to reduce the volume of the airbag 5, and the polyester-cotton yarn wrapped on the surface of the airbag 5 can be easily removed, greatly simplifying the yarn handling process.

[0030] like Figure 1 and Figure 2 As shown, multiple protruding bladders 6 are fixed in the middle of the side wall of the airbag 5; the multiple protruding bladders 6 and the airbag 5 are hollow and connected; the protruding bladders 6 are made of elastic material; by setting the protruding bladders 6, this step can arrange the polyester-cotton yarn according to a predetermined path during the winding process, which helps to reduce the offset and crossing of the yarn during the winding process, making the yarn arrangement more neat and orderly.

[0031] like Figure 1 and Figure 4 As shown, an anti-wear pad 7 is fixed in the middle of the side wall of the pulley 32; the anti-wear pad 7 is made of elastic material; by setting the anti-wear pad 7 on the outside of the pulley 32, this step can reduce the direct friction between the polyester-cotton yarn and the pulley 32, thereby reducing the wear of the polyester-cotton yarn, helping to extend the service life of the polyester-cotton yarn, and reducing the replacement frequency and cost.

[0032] Working principle: The operator places the take-up roller 14 onto the outside of the adjusting component, then adjusts the size of the adjusting component so that it supports the take-up roller 14 from the inside. Next, the polyester-cotton yarn is wound around the side wall of the unwind roller 15. One end of the polyester-cotton yarn is then pulled and looped around the bottom of the guide component, subsequently winding onto the material-taking component on the side wall of the take-up roller 14. At this point, the operator starts the drive motor 13, which drives the adjusting component to rotate, causing the adjusting component to rotate the take-up roller 14. This causes the take-up roller 14 to rotate synchronously with the material-taking component. Guided by the guide component, the polyester-cotton yarn winds from the side wall of the unwind roller 15 onto the take-up roller 14. After winding is complete, the operator... The operator uses the material handling component to remove the polyester-cotton yarn from the take-up roller 14. During the winding process, the cleaning component sucks up flying dust and other particles to prevent dust from adhering to the polyester-cotton yarn. After the operator fits the take-up roller 14 onto the outside of the multiple adjusting plates 24, the first electric actuator 2 and the second electric actuator 21 are activated. At this time, the first electric actuator 2 and the second electric actuator 21 drive the movable rod 22 to move, causing the movable rod 22 to pull the multiple support rods 26 on the side wall to rotate. When the support rods 26 rotate, they pull the multiple adjusting plates 24 to slide along the side wall of the fixed seat 23. At this time, the multiple adjusting plates 24 will change the outward opening distance as the movable rod 22 moves, adjusting the adjusting plates 24. Once the take-up roller 14 is positioned to be properly supported, stop the first electric push rod 2 and the second electric push rod 21, then start the drive motor 13. The drive motor 13 will then rotate the first electric push rod 2, causing the first electric push rod 2 to synchronously rotate the second electric push rod 21, the movable rod 22, the fixed seat 23, the adjusting plate 24, the fixed plate 25, the support rod 26, the take-up roller 14, and the polyester-cotton yarn wound around the outside of the take-up roller 14. At this time, the polyester-cotton yarn will wrap around the surface of the take-up roller 14 from the unwinding roller 15. As the polyester-cotton yarn winds around the side wall of the take-up roller 14 after passing around the bottom of the pulley 32, the operator starts the reciprocating motor 3. The reciprocating motor 3 will then rotate the threaded rod 31. When rotating, the movable ring on its side wall slides along the threaded rod 31, causing the movable ring to drive the pulley 32 to move synchronously. When the polyester-cotton yarn moves at the bottom of the pulley 32, the pulley 32 will rotate on the movable ring. The operator connects the air extraction pipe 41 to the vacuum pump. Since the dust collection box 4, the air extraction pipe 41 and the dust suction hole 42 are connected, the vacuum pump will drive the dust and other particles generated during the winding process into the dust collection box 4 through the airflow. When all the polyester-cotton yarn is wound on the side wall of the airbag 5, the operator opens the connecting pipe 51 to release the gas inside the airbag 5, causing the airbag 5 to become deflated and no longer press against the polyester-cotton yarn. At this time, the operator can easily remove the polyester-cotton yarn from the airbag 5.
