[0002] During the winding process on traditional textile machines, the winding mechanism often suffers from improper operation or mechanical failure, causing the yarn to loosen during high-speed rotation. Traditional winding devices typically rely on friction to prevent backflow, but these methods are prone to wear and tear over time and cannot completely prevent the problem of loose yarn. Furthermore, these traditional methods lack stability and reliability when operating in high-speed, high-intensity environments, which can easily lead to reduced production efficiency and product quality issues.

[0023] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

They are only for the convenience of describing this application and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on this application.

[0025] Furthermore, it should be understood that for ease of description, the sizes of the various components shown in the drawings are not drawn according to actual proportions. For example, the thickness or width of certain layers may be exaggerated relative to other layers.

[0026] It should be noted that like numbers and letters represent similar items in the following figures, so once an item is defined or described in one figure, it will not need to be further discussed and described in detail in the description of the subsequent figures.

[0027] In order to solve the technical problems in the background technology, such as Figure 1-2 As shown, the present application provides a technical solution: an anti-backward winding device for a textile machine, which has the following characteristics:

[0028] The stepped base 1 is made of durable metal, offering excellent stability and load-bearing capacity. A mounting slot 2 is provided within the base 1 for mounting the U-shaped frame 3 and motor 12. The U-shaped frame 3 is secured within the mounting slot 2 of the base 1. Two opposing side panels 4 are provided at each end of the U-shaped frame 3. A passage is formed between the side panels 4 for accommodating the rotating shaft 5. The rotating shaft 5 passes through the two side panels 4 and fits tightly with them to maintain stability. The rotating shaft 5 is made of high-strength, wear-resistant materials such as stainless steel to ensure reliability during long-term operation. The rotating shaft 5 can rotate relative to the side panels 4. A sleeve 6 is mounted on the rotating shaft 5 and rotates with it. A groove 7 is provided on the sleeve 6 for accommodating the wire used in the winding device. The wire is wound around the sleeve 6. The sleeve 6 is removable from the rotating shaft 5. The sleeve 6 can be removed by removing the rotating shaft 5 from the hole in the side panels 4. The ratchet 8 is provided at one end of the rotating shaft 5, and a plurality of ratchet teeth are provided on the surface of the ratchet 8 for cooperating with the pawl 9. One end of the pawl 9 is hinged to the side plate 4, and the other end is a free end 10. Under the action of gravity, the free end 10 droops downward, so that the pawl 9 cooperates with the ratchet 8 to form a ratchet mechanism 11. When the rotating shaft 5 rotates, the ratchet 8 drives the movement; when encountering a wire jam or other problems that cause the sleeve 6 to rotate in the reverse direction, the ratchet mechanism 11 formed by the pawl 9 and the ratchet 8 realizes the anti-backward function. The motor 12 is installed on the base 1, and the motor 12 is connected to one end of the rotating shaft 5 for driving the rotating shaft 5 to rotate.

[0029] When in use, place the wire in the groove 7 on the sleeve 6; start the motor 12 to drive the shaft 5 to rotate; during the rotation of the shaft 5, the ratchet 8 drives the pawl 9 to move to achieve the anti-backward function; when the wire is wound, turn off the motor 12 and take out the wire.

[0030] In some embodiments, a protrusion 13 is provided at the free end 10 of the pawl 9. The protrusion 13 is cylindrical and made of metal, such as iron, to provide a weighted effect. This allows the pawl 9 to exert a downward force under gravity, thereby engaging with the teeth of the ratchet wheel 8 and preventing the ratchet wheel 8 from rolling back. The weighted effect of the protrusion 13 allows the pawl 9 to engage with the ratchet wheel 8 more stably, improving the reliability of the mechanism.

[0031] Furthermore, the slot 14 is provided on the outer side wall of the sleeve 6, and the specific position is as follows: Figure 1 As shown, slot 14 and groove 7 communicate within sleeve 6. First, insert one end of the wire through slot 14. Due to the design of slot 14, the wire can pass smoothly through slot 14 and into sleeve 6. After the wire is introduced, it enters groove 7 and exits sleeve 6. By rotating sleeve 6, the multiple strands of wire are pressed against sleeve 6, and the wires are initially positioned. Sleeve 6 is further rotated to wrap around it.

[0032] It should be noted that the guide rod 15 is connected to the top of the two side plates 4. The function of the guide rod 15 is to guide the wire into the winding device to ensure that the wire does not deviate from the track during the winding process.

[0033] Furthermore, the guide rod 15 is linear and serves to guide and support the sliding hook 16. Made of stainless steel, it offers excellent wear and corrosion resistance. The sliding hook 16 is S-shaped, with a hook portion at one end that securely hooks onto the guide rod 15. The other end of the hook has a curved portion for threading the wire. The S-shaped design of the hook 16 provides greater stability and adaptability during movement, effectively reducing damage caused by vibration or wire jamming.

[0034] It should be noted that a protrusion 17 is provided on the side wall of the mounting groove 2, and the protrusion 17 is a pointed-angle type. A groove 18 is provided on both sides of the side plate 4, and the shape and size of the groove 18 should match the protrusion 17 so that the two can be embedded in each other, thereby improving the stability of the installation.

[0035] It should be noted that the rotating hole 19 is provided at one end of the rotating shaft 5, and its inner diameter matches the outer diameter of the wrench 20, so that the wrench 20 can be easily inserted into the rotating hole 19. By rotating the wrench 20, the tightness of the coil can be fine-tuned by rotating the rotating shaft 5 until the preset requirement is met and the winding work can be carried out.

[0036] Furthermore, the distance between the sleeve 6 and the base 1 is equal to the distance between the guide rod 15 and the sleeve 6. This distance provides sufficient space for winding and also provides space for the wire after it is coiled. The design of equal distance between the upper and lower parts avoids interference between the wires during the winding process.

[0037] Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
