[0003] However, the inner and outer discs of the current winding aids on the market lack positioning structures, resulting in poor synchronization and easy slippage during winding, which leads to chip displacement and requires manual correction, affecting production efficiency. Furthermore, the chips lack protective structures, making them susceptible to physical damage from pressure on the wire. In addition, the winding aids are made of metal, which can easily scratch the wire. The thickness of the tools differs from that of the reel winding fixture, requiring adjustment of equipment parameters during mode switching, making operation complex and affecting production continuity.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0018] like Figures 1 to 4 As shown, an auxiliary tool for winding discless 3D printing filament products includes a disc A 1 and a disc B 2. Disc A 1 has a cross groove 11, and disc B 2 has a cross protrusion 21, which is adapted to the cross groove 11. Both disc A 1 and disc B 2 have coaxially arranged mounting holes 6, chip clearance positions 5, and steps 4. Discs A 1 and B 2 are made of 3D printing filament. In this configuration, the cross groove 11 and the cross protrusion 21 are adapted to achieve the positioning of discs A 1 and B 2. The mounting holes 6 provide a foundation for the installation of both discs with the winding machine mold position. The chip clearance positions 5 are used to accommodate chips. The steps 4 can protect the inner shaft of the paper. The material of the 3D printing filament can reduce the risk of filament scratches. All components work together to meet the auxiliary needs of winding discless products.

[0019] like Figures 1 to 4 As shown, in a specific embodiment, the cross groove 11 is formed in the center area of ​​the end face of disk A 1, and the cross groove 11 extends radially along disk A 1. In this configuration, placing the cross groove 11 at the center of the end face of disk A 1 and extending radially enables more uniform force distribution and precise positioning when subsequently docking with the cross protrusion 21 of disk B 2, ensuring that disk A 1 and disk B 2 remain coaxial and synchronized during rotation.

[0020] like Figures 1 to 4 As shown, a cross-shaped protrusion 21 is further provided in the center area of ​​the end face of disk B 2. The cross-shaped protrusion 21 extends radially along disk B 2, and the height of the cross-shaped protrusion 21 is adapted to the depth of the cross-shaped groove 11. In this configuration, the cross-shaped protrusion 21 and the cross-shaped groove 11 are correspondingly opened in the center area of ​​the two disks and extend radially. With the matching height and depth, disk A 1 and disk B 2 can be tightly fitted together, avoiding relative slippage during winding and ensuring synchronous operation of the inner and outer disks.

[0021] like Figures 1 to 4 As shown, furthermore, the end face of disk A1 with the cross groove 11 has a circular groove 3. The circular groove 3 is coaxially arranged with the mounting hole 6, and the diameter of the circular groove 3 is larger than the diameter of the mounting hole 6. In this arrangement, the circular groove 3 is coaxial with the mounting hole 6 and has a larger diameter, which can accommodate the head of the fastener. When disk A1 is connected to the winding machine mold position through the mounting hole 6, the fastener can fit against the bottom of the circular groove 3, improving the flatness and stability of disk A1 after installation.

[0022] like Figures 1 to 4 As shown, furthermore, the end face of disk B 2 with the cross protrusion 21 has a circular groove 3. The circular groove 3 is coaxially arranged with the mounting hole 6, and the diameter of the circular groove 3 is larger than the diameter of the mounting hole 6. In this arrangement, corresponding to the circular groove 3 structure of disk A 1, the circular groove 3 on disk B 2 cooperates with the mounting hole 6, which can not only provide installation space for fasteners, but also ensure the firmness of the connection between disk B 2 and the winding machine mold position, while maintaining the structural consistency of the two disks after assembly.

[0023] like Figures 1 to 4 As shown, furthermore, four chip clearance positions 5 are provided on both disks A1 and B2. These four chip clearance positions 5 are evenly distributed along the circumference of disks A1 and B2, and are cross-shaped grooves. In this configuration, the four cross-shaped groove chip clearance positions 5 are evenly distributed along the circumference of the disk body, corresponding to the chip mounting positions on the inner shaft of the paper. The cross-shaped grooves effectively limit the movement of the chips, preventing them from shifting during the winding process.

[0024] like Figures 1 to 4 As shown, furthermore, four steps 4 are integrally connected to the side walls of both disk A1 and disk B2. The four steps 4 are evenly distributed along the circumference of disk A1 and disk B2, and are vertically protruding around the corresponding disk body. In this configuration, the four steps 4 are evenly distributed along the circumference of the disk body's side wall and are vertically protruding, which can support the inner shaft of the paper during the winding process, preventing the inner shaft of the paper from being damaged due to concentrated force. At the same time, the integrally connected structure ensures the load-bearing stability of the steps 4.

[0025] like Figures 1 to 4 As shown, the thickness of disks A1 and B2 is consistent with the thickness of the 3D printing filament material disk. The mounting holes 6 penetrate the thickness direction of disks A1 and B2 respectively, and the diameter of the mounting holes 6 matches the mounting shaft diameter of the winding machine mold position. In this setup, the disk thickness is consistent with the material disk, eliminating the need to adjust equipment parameters when switching between disk-based and diskless winding. The mounting holes 6 penetrating the disks, with their matching diameter to the mounting shaft diameter, ensure that disks A1 and B2 can be stably mounted on the winding machine mold position.

[0026] The implementation principle of the auxiliary tool for winding 3D printing filament discless products in this embodiment is as follows: When the auxiliary tool for winding 3D printing filament discless products is working, disk A1 and disk B2 are first installed on the mold position of the winding machine through their respective coaxially opened assembly holes 6. The diameter of the assembly hole 6 is adapted to the mounting shaft diameter of the winding machine mold position, ensuring that disk A1 and disk B2 are stably assembled and rotate coaxially with the mounting shaft of the winding machine.

[0027] During installation, the radially extending cross groove 11 on the center area of ​​the end face of disk A1 matches the radially extending cross protrusion 21 on the center area of ​​the end face of disk B2, thus positioning disks A1 and B2 and preventing relative sliding during winding, ensuring synchronous operation of the inner and outer disks. Both the end face of disk A1 with the cross groove 11 and the end face of disk B2 with the cross protrusion 21 have circular grooves 3 coaxial with the mounting holes 6, and the diameter of the circular grooves 3 is larger than the diameter of the mounting holes 6. This, combined with fasteners, further enhances the stability of the connection between disks A1 and B2 and the winding machine mold.

[0028] Both disks A1 and B2 have four cross-shaped slots 5 evenly spaced along the circumference. Before winding, the chips are placed in the corresponding chip clearance slots 5. The cross-shaped slots can limit the chips and prevent the winding line from directly pressing on the chips during the winding process.

[0029] Both disk A1 and disk B2 have four steps 4 evenly distributed along the circumference on their side walls. These steps 4 are vertically protruding around the corresponding disk body and can support the inner shaft of the paper during winding, preventing the inner shaft of the paper from being damaged.

[0030] Furthermore, the thickness of disks A1 and B2 is consistent with the thickness of the 3D printing filament material disk, so that there is no need to adjust the winding machine cable clamp parameters when switching between disked and diskless winding. Combined with the fact that disks A1 and B2 are made of 3D printing filament, the risk of the filament being scratched during the winding process is reduced, ultimately achieving stable winding of diskless products.
