[0002] Anti-winding equipment for sewing thread drafting is a specialized device used in the sewing thread production process to ensure smooth drafting of the thread and prevent problems such as winding and tangling. By controlling tension and path, it maintains thread stability, avoids winding caused by uneven tension and shaking, ensures uniform thread thickness and stable physical properties, and improves quality. This equipment reduces downtime and cleaning time, prevents thread breakage and tangling, increases output, reduces raw material waste, and allows for more efficient use of sewing thread, reducing production costs, minimizing equipment wear, extending service life, lowering maintenance costs, ensuring thread quality, and improving product consistency and pass rate.
[0003] Currently, when changing the thread spool in sewing thread tensioning anti-winding equipment on the market, the operator needs to stop the machine first, and then manually remove the original thread spool. This involves multiple steps and complicated operations, such as loosening the screws or clips that fix the thread spool. After disassembly, a new thread spool is installed, and its position and tension are readjusted to ensure that the thread spool can rotate stably and supply sewing thread. Frequent thread spool replacement may also increase the machine's downtime and reduce overall production efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a sewing thread anti-winding device that can automatically replace the thread spool without the need for cumbersome manual disassembly and installation, thereby reducing the time and labor costs required to replace the thread spool and improving production efficiency.
[0005] The specific technical solution adopted by this utility model is as follows:
[0006] A sewing thread anti-winding device includes a support frame, a control panel fixedly mounted on one side of the support frame, a spool rotatably connected to one side of the support frame, a thread guiding device fixedly mounted on the side of the support frame near the spool, a guide mechanism fixedly mounted on the side of the support frame near the bottom of the thread guiding device, a thread-carrying drum sleeved on the surface of the spool, a circular hole on one side of the thread-carrying drum, and a telescopic component and a replacement component provided on the support frame.
[0007] Preferably, the telescopic assembly includes an electric telescopic rod fixedly connected to one side of the support frame. The piston rod of the electric telescopic rod is rotatably connected to an insert rod. One end of the insert rod is inserted into a round hole. A guide plate is fixedly connected to the bottom of the support frame near the insert rod. A storage groove is installed on the bottom of the guide plate at the end away from the support frame.
[0008] Preferably, the replacement component includes a support platform fixedly connected to one side of the bottom of the guide plate. A U-shaped groove is fixedly connected to the support platform. Multiple wireless rollers are installed on the top of the support platform and inside the U-shaped groove. Each wireless roller has a slot at one end. A square hole is opened at the end of the U-shaped groove away from the guide plate. An electric push rod is fixedly connected to the top of the support platform near the square hole and outside the U-shaped groove. The piston rod of the electric push rod is fixedly connected to a push plate, and one side of the push plate is attached to the wireless roller.
[0009] Preferably, a limiting rod is fixedly connected to the inner side of the U-shaped groove, and the surface of the limiting rod is inserted into each slot.

[0012] The technical effects achieved by this utility model are as follows:
[0013] This utility model discloses an anti-winding device for sewing thread pulling. By incorporating a telescopic component and a replacement component, an electric telescopic rod is driven via a control panel. This pushes an insert rod, moving the thread roll forward to initially separate the thread roll from the spool. Then, when the thread roll is completely detached from the spool, the electric telescopic rod continues to push the insert rod, moving the thread roll to the top of the storage tank. When the thread roll is completely away from the support platform, gravity causes the insert rod to rotate to a certain angle, allowing the thread roll to fall into the storage tank. Subsequently, the device is driven... The electric telescopic rod drives the insertion rod backward. When the insertion rod slides on the top of the support platform, it engages with the limit rod, stopping the electric telescopic rod from moving backward. The control panel drives the electric push rod to move the push plate towards the insertion rod, so that the slot can be inserted into the surface of the insertion rod. Then the electric telescopic rod moves again, so that the wireless reel can be securely inserted into the surface of the reel. This device can automatically change the reel with wire, eliminating the need for cumbersome manual disassembly and installation, thereby reducing the time and labor costs required to change the reel and improving production efficiency.

Detailed Implementation
[0020] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0021] like Figures 1-4 As shown, a sewing thread anti-winding device includes a support frame 1, a control panel fixedly installed on one side of the support frame 1, a roller 2 rotatably connected to one side of the support frame 1, a thread guiding device 3 fixedly installed on the side of the support frame 1 near the roller 2, a guide mechanism 4 fixedly installed on the side of the support frame 1 near the bottom of the thread guiding device 3, a thread-carrying drum 5 sleeved on the surface of the roller 2, a round hole 6 opened on one side of the thread-carrying drum 5, and a telescopic component and a replacement component provided on the support frame 1.
[0022] The control panel controls the operation of the entire device. The support frame 1 supports the spool 2, the thread-laying device 3, and the guide mechanism 4. The thread spool 5 stores the sewing thread. The thread spool 5 is placed on the spool 2 and rotated to wind the sewing thread at a constant speed. By controlling the rotation speed and winding direction of the spool 2, the sewing thread can be evenly wound onto the thread spool 5. The design of the thread-laying device 3 prevents the sewing thread from being too tight or too loose in certain areas, thus preventing tangling and ensuring that the sewing thread is neatly arranged on the thread spool 5. Further improve winding quality and reduce tangling; the guide mechanism 4 can guide the sewing thread to move along a predetermined path, restrict its lateral movement and swaying, keep the thread moving in a straight line, and reduce the possibility of tangling. The telescopic component makes it easy for users to replace the thread roll 5 without disassembly, which greatly improves work efficiency; when the thread roll needs to be replaced, the control panel activates the electric telescopic rod 7, which drives the thread roll 5 to move axially along the shaft 2, so that the thread roll 5 is separated from the shaft 2. The replacement component makes it easy for users to replace the thread roll 5.
[0023] like Figure 1 and Figure 2 As shown, the telescopic assembly includes an electric telescopic rod 7 fixedly connected to one side of the support frame 1. The piston rod of the electric telescopic rod 7 is rotatably connected to an insertion rod 8. One end of the insertion rod 8 is inserted into a round hole 6. A guide plate 9 is fixedly connected to the bottom of the support frame 1 near the insertion rod 8. A storage slot 10 is installed at the bottom of the guide plate 9 away from the support frame 1.
[0024] Specifically, the electric telescopic rod 7 is driven by the control panel, which in turn pushes the insertion rod 8 to move the wire reel 5 forward, so that the wire reel 5 can be separated from the reel 2. Then, when the wire reel 5 is completely separated from the reel 2, the electric telescopic rod 7 continues to push the insertion rod 8 to move the wire reel 5 to the top of the storage tank 10. When the wire reel 5 is completely away from the support platform 11, the wire reel 5 will be affected by gravity, causing the insertion rod 8 to rotate to a certain angle. Finally, the wire reel 5 falls into the storage tank 10, so that the wire reel 5 can be quickly and conveniently replaced without tedious manual disassembly and installation.
[0025] like Figure 2 and Figure 3 As shown, the replacement component includes a support platform 11 fixedly connected to one side of the bottom of the guide plate 9. A U-shaped groove 12 is fixedly connected to the support platform 11. Multiple wireless rollers 13 are installed on the top of the support platform 11 and inside the U-shaped groove 12. Each wireless roller 13 has a slot 14 at one end. A square hole 15 is opened at the end of the U-shaped groove 12 away from the guide plate 9. An electric push rod 16 is fixedly connected to the top of the support platform 11 near the square hole 15 and outside the U-shaped groove 12. The piston rod of the electric push rod 16 is fixedly connected to a push plate 17, and one side of the push plate 17 is attached to the wireless roller 13.
[0026] When the wire reel 5 falls into the storage slot 10, the electric telescopic rod 7 drives the insertion rod 8 to push backward. When the insertion rod 8 slides on the top of the support platform 11, it engages with the limit rod 18, stopping the electric telescopic rod 7 from moving backward. The electric push rod 16 is driven by the control panel, which in turn drives the push plate 17 to push the wireless reel 13 toward the insertion rod 8, so that the slot 14 is inserted into the surface of the insertion rod 8. Then the electric telescopic rod 7 moves again, so that the wireless reel 13 can be inserted into the surface of the reel 2, so that the wireless reel 13 can be securely installed on the reel 2.
[0027] like Figure 2 As shown, a limiting rod 18 is fixedly connected to the inner side of the U-shaped groove 12, and the surface of the limiting rod 18 is inserted into each slot 14.
[0028] Specifically, the design of the limiting rod 18 prevents the wireless reel 13 from rolling. Under the action of the limiting rod 18, the stability of the wireless reel 13 during movement is ensured, avoiding inaccurate insertion caused by shaking. The limiting rod 18 also serves as a guide, enabling the wireless reel 13 to move smoothly along the predetermined trajectory until the slot 14 is fully inserted into the surface of the insertion rod 8, thereby achieving a stable connection between the wire reel 5 and the reel 2.
[0029] like Figure 2 As shown, the guide plate 9 has an L-shaped structure and is inclined near the top of the storage tank 10.
[0030] The L-shaped structure design not only facilitates the docking of the guide plate 9 with the top of the storage tank 10, but also effectively guides the wire reel 5 to fall smoothly into the storage tank 10, improving the smoothness and efficiency of the operation.
[0031] like Figure 4 As shown, a sliding groove 19 is provided on the inner wall of the U-shaped groove 12 near the insertion rod 8. A triangular block 20 is slidably connected in the sliding groove 19. A spring 21 is fixedly connected to the side of the sliding groove 19 and the triangular block 20 that are close to each other.
[0032] Specifically, the design of the slide groove 19 and the triangular block 20, under the action of the push plate 17, when the wireless reel 13 needs to be pushed, the cooperation of the slide groove 19 and the triangular block 20 can effectively limit other wireless reels 13, ensuring that only the target wireless reel 13 can move to the outside of the U-shaped groove 12. The elastic design of the spring 21 allows the triangular block 20 to limit the wireless reel 13 again, thereby avoiding chaotic movement caused by misoperation or shaking.
[0033] The working principle of this utility model is as follows: First, the electric telescopic rod 7 is driven by the control panel, which in turn pushes the insertion rod 8 to move the wire reel 5 forward, causing the wire reel 5 to separate from the reel 2. Then, when the wire reel 5 is completely detached from the reel 2, the electric telescopic rod 7 continues to push the insertion rod 8 to move the wire reel 5 to the top of the storage tank 10. When the wire reel 5 is completely away from the support platform 11, the wire reel 5 will be affected by gravity, causing the insertion rod 8 to rotate to a certain angle, and finally the wire reel 5 falls into the storage tank 10; then the drive... The electric telescopic rod 7 drives the insertion rod 8 to push backward. When the insertion rod 8 slides on the top of the support platform 11, it engages with the limit rod 18, stopping the electric telescopic rod 7 from moving backward. The electric push rod 16 is driven by the control panel to drive the push plate 17 to push the wireless drum 13 towards the insertion rod 8, so that the slot 14 is inserted into the surface of the insertion rod 8. Then the electric telescopic rod 7 moves again, so that the wireless drum 13 can be inserted into the surface of the reel 2. Finally, the wireless drum 13 is securely installed on the reel 2, thus completing the replacement of the wire drum 5.
[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
