DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0034] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0035] In one embodiment of the present invention, see Figure 1 , Figure 2 and Figure 3 The 3D printing wire winding device comprises a workbench 1, a support frame 2 is symmetrically arranged at the bottom of the workbench 1, a rotating column 7 is rotatably arranged on the workbench 1, a rotating component connected to the rotating column 7 is arranged at the bottom of the workbench 1, a winding roller 8 is slidably sleeved on the outer side of the rotating column 7, a positioning component movably abutted with the winding roller 8 is arranged on the top of the rotating column 7, and the rotating column 7 on the workbench 1 is symmetrically provided with an installation frame 9, an opening is arranged on the side of the installation frame 9 close to each other, and an abutment component movably abutted with the outer wall of the winding roller 8 is movably arranged on the installation frame 9.

[0036] In this embodiment, the rotating component drives the winding roller 8 to rotate synchronously by driving the rotating column 7 to rotate and the rotating column 7 and the winding roller 8 to slide together, thereby realizing the winding operation of the 3D printing wire. The relative position of the winding roller 8 and the rotating column 7 can be fixed by the positioning component to avoid the winding roller 8 from moving up during the winding process of the 3D printing wire, thereby improving the stability of the winding of the 3D printing wire. The abutment component can ensure that the wire always remains in a fitted state during the winding process to avoid the wire stretching and affecting the winding effect. The wire has the effects of stable winding, effective positioning, reliable fitting, simple structure, convenient operation, and simple and practical use.

[0037] In one embodiment of the present invention, see Figure 1 and Figure 2 The rotating assembly includes a bevel gear 3 connected to a rotating column 7, a bevel gear 2 4 meshing with the bevel gear 3 is movably provided at the bottom of the workbench 1, the bevel gear 2 4 is connected to a rotating motor 5, and the bottom of the workbench 1 is connected to the rotating motor 5 through a mounting frame 6.

[0038] In this embodiment, the rotating motor 5 drives the bevel gear 2 4 to rotate, and the bevel gear 2 4 drives the rotating column 7 to rotate by meshing with the bevel gear 1 3. The rotating column 7 drives the winding roller 8 to rotate synchronously by slidingly sleeved with the winding roller 8, so as to realize the winding processing of the wire.

[0039] In one embodiment of the present invention, see Figure 1 and Figure 4 The positioning assembly includes side plates 11 symmetrically arranged on the top of the rotating column 7, and rotating rods 12 are symmetrically and rotatably connected between the side plates 11. Abutment rollers 14 that are symmetrically and movably abut against the top of the winding roller 8 are movably arranged on the outer side of the rotating column 7. A connecting plate 13 is connected between the rotating rod 12 and the corresponding abutment roller 14, and a push plate 15 is provided on the connecting plate 13. A spring 16 is connected between the symmetrically arranged connecting plates 13.

[0040] In this embodiment, in the initial state, the spring 16 is at its original length and the abutment roller 14 is at the lowest point. When the winding roller 8 needs to be placed, the symmetrically arranged push plates 15 are pushed close to each other, the spring 16 is stressed and contracts, the push plates 15 drive the connecting plates 13 to rotate upward around the rotating rod 12, and the connecting plates 13 drive the abutment rollers 14 to rotate upward synchronously, which can reduce the spacing between the symmetrically arranged abutment rollers 14, make the bottom opening of the winding roller 8 correspond to the abutment roller 14 and make the abutment roller 14 contact with the inner wall of the winding roller 8, release the push plate 15, and push the winding roller 8 downward, the abutment roller 14 is in active contact with the inner wall of the winding roller 8, and when the abutment roller 14 passes through the top of the winding roller 8 When the wire is unthreaded, the spring 16 stretches and pushes the symmetrically arranged push plates 15 away from each other, and the push plates 15 drive the connecting plates 13 to rotate downward around the rotating rod 12. The connecting plates 13 drive the abutment rollers 14 to rotate synchronously downward to position the top of the winding roller 8, which can effectively prevent the winding roller 8 from separating from the rotating column 7 during the rotation process. When the wire winding is completed, the winding roller 8 is pulled upward, and the winding roller 8 drives the connecting plates 13 to rotate upward around the rotating rod 12 by actively abutting with the abutment rollers 14. The spring 16 is stressed and contracts. At the same time, the spacing between the symmetrically arranged abutment rollers 14 is reduced, which is convenient for the extraction of the winding roller 8, wherein the connecting plates 13 are configured as L-shaped plates.

[0041] In one embodiment of the present invention, see Figure 1 , Figure 2 and Figure 3 The abutment assembly includes an abutment frame 10 symmetrically arranged about the center of the rotating column 7, one end of the abutment frame 10 is rotatably connected to the mounting frame 9, and the other end of the abutment frame 10 is movably abutted with the outer wall of the winding roller 8, a gear portion 17 is provided on the outer side of one end of the abutment frame 10 close to the mounting frame 9, a sliding tooth plate 18 meshing with the gear portion 17 is slidably provided inside the mounting frame 9, a guide rod 19 and a guide rod 20 slidably matched with the sliding tooth plate 18 are provided inside the mounting frame 9, and a spring 21 sleeved on the outer side of the guide rod 20 is connected between the mounting frame 9 and the sliding tooth plate 18.

[0042] In this embodiment, in the initial state, spring two 21 is at its original length, and one end of the abutment frame 10 abuts against the outer wall of the winding roller 8. When the wire on the winding roller 8 begins to be wound, the winding of the wire gradually increases the inner diameter of the wire winding. During the winding process, the wire will push the end of the abutment frame 10 close to the winding roller 8 to rotate outward, and the abutment frame 10 drives the gear part 17 to rotate. The gear part 17 drives the sliding tooth plate 18 to move by meshing with the sliding tooth plate 18 and the sliding tooth plate 18 slidingly cooperates with the guide rod one 19 and the guide rod two 20. The spring two 21 is stressed and contracts, which can make the end of the abutment frame 10 close to the winding roller 8 apply pressure to the surface of the wound wire, which can effectively ensure that the outer ring wire is always in contact with the inner ring wire during the winding process, thereby improving the wire winding effect, wherein the sliding tooth plate 18 is set to a C-shaped tooth plate.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
