[0029] 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.

[0030] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0031] In one embodiment of the present invention, see Figure 1The consumable material guiding mechanism of a 3D printing device comprises a mounting plate 1, on which a winding roller 2 for placing a material wire 4 is rotatably provided, and on which a traction roller group 1 5, a traction roller group 2 6 and a traction roller group 3 11 are provided from left to right in sequence, and on which a guide cylinder 12 installed on the mounting plate 1 is provided at one end of the traction roller group 3 11 away from the winding roller 2, and one end of the material wire 4 is connected to the winding roller 2, and the other end of the material wire 4 passes through the traction roller group 1 5, the traction roller group 2 6, the traction roller group 3 11 and the guide cylinder 12 in sequence and extends out, and on the mounting plate 1 a positioning component is provided between the traction roller group 1 5 and the traction roller group 2 6, and on the mounting plate 1 a traction component is provided between the traction roller group 2 6 and the traction roller group 3 11.

[0032] In this embodiment, the filament 4 can be stably guided through the cooperation of the traction roller group 1 5, the traction roller group 2 6, the traction roller group 3 11 and the guide cylinder 12, and the filament 4 can be stably positioned through the positioning component. The excess filament 4 can be tightened through the traction component to prevent the filament 4 from being entangled in the 3D printer and causing damage to related structures, thereby improving the safety and service life of the device, and having the effects of effective guidance, stable positioning, reliable traction, flexible adjustment, convenient operation, and simple and practical use. Positioning plates 3 are provided on both sides of the mounting plate 1 to facilitate the installation of the device.

[0033] In one embodiment of the present invention, see Figure 1 The positioning assembly includes a support plate 7 arranged on the mounting plate 1, the support plate 7 is located between the traction roller group 1 5 and the traction roller group 2 6 and is in contact with the wire 4, and an electric telescopic rod 9 is provided on the mounting plate 1 and is located between the traction roller group 1 5 and the traction roller group 2 6. The electric telescopic rod 9 is located on the side of the wire 4 away from the support plate 7, and the end of the electric telescopic rod 9 close to the wire 4 is connected to a clamping plate 8 that is in active contact with the wire 4.

[0034] In this embodiment, in the initial state, the clamping plate 8 is away from the supporting plate 7, and the wire 4 is in contact with the supporting plate 7. When too much wire 4 is pulled out, the excess wire 4 needs to be tightened and pulled, and the operator controls the electric telescopic rod 9 to extend and push the clamping plate 8 close to the wire 4. The clamping plate 8 clamps the wire 4 locally by cooperating with the supporting plate 7, which is convenient for the tightening operation of the outer wire 4. At this time, the wire 4 is wavy. When the wire 4 returns to the horizontal state, the operator controls the electric telescopic rod 9 to contract and drive the clamping plate 8 to move upward, releases the positioning of the wire 4, and facilitates the continuous guidance of the wire 4.

[0035] In one embodiment of the present invention, see Figure 1 , Figure 2 , Figure 3 and Figure 4The traction assembly includes a transmission gear 22 rotatably arranged on the mounting plate 1, the transmission gear 22 is located between the clamping plate 8 and the traction roller group 3 11, the mounting plate 1 is symmetrically provided with a slide groove 10 about the center of the transmission gear 22, the slide groove 10 is movably provided with a movable plate 13, a guide plate 20 slidably matched with the slide groove 10 is installed on one side of the movable plate 13, a side rack 21 meshing with the transmission gear 22 is provided on the side of the movable plate 13 close to the transmission gear 22, a fixed roller 14 is rotatably provided at one end of the movable plate 13, and the movable plate A second slide groove 16 is provided on 13, and a guide rod 17 is connected to the second slide groove 16. A sliding seat 18 that slides and cooperates with the second slide groove 16 is slidably provided on the guide rod 17. A movable roller 15 corresponding to the fixed roller 14 is rotatably provided on the sliding seat 18. The movable roller 15 clamps the wire 4 by cooperating with the fixed roller 14. A spring 19 that is sleeved on the outside of the guide rod 17 is connected between the second slide groove 16 and the sliding seat 18. A rotating gear 23 that meshes with a transmission gear 22 is rotatably provided on the mounting plate 1, and the rotating gear 23 is connected to a rotating motor 24.

[0036] In this embodiment, in the initial state, the line between the two movable plates 13 is in a horizontal state. When there is too much external wire 4, the positioning component clamps and fixes one end of the wire 4, and the rotating motor 24 drives the rotating gear 23 to rotate counterclockwise. The rotating gear 23 drives the transmission gear 22 to rotate clockwise through gear meshing. The transmission gear 22 drives the corresponding movable plate 13 to move along the slide groove 10 by meshing with the side rack 21. The movable plate 13 drives the fixed roller 14 and the movable roller 15 to move synchronously, extending the traction length of the wire 4 between the clamping plate 8 and the traction roller group 3 11, and the wire 4 can be tightened. When the 3D printer continues to use the wire 4, the rotating motor 24 drives the rotating gear 23 to rotate counterclockwise. The rotating gear 23 drives the transmission gear 22 to rotate clockwise through gear meshing. The transmission gear 22 drives the corresponding movable plate 13 to move along the slide groove 10 by meshing with the side rack 21. The movable plate 13 drives the fixed roller 14 and the movable roller 15 to move synchronously, which extends the traction length of the wire 4 between the clamping plate 8 and the traction roller group 3 11, and the wire 4 can be tightened. When the 3D printer continues to use the wire 4, the rotating motor 24 drives the rotating gear 23 to rotate counterclockwise. The rotating gear 23 rotates clockwise, and the rotating gear 23 drives the transmission gear 22 to rotate counterclockwise through gear meshing. The transmission gear 22 drives the corresponding movable plate 13 to move along the slide groove 10 by meshing with the side rack 21. The movable plate 13 drives the fixed roller 14 and the movable roller 15 to move synchronously, shortening the traction length of the wire 4 between the clamping plate 8 and the traction roller group three 11, which is convenient for the traction and use of the external wire 4. When the connecting line between the two movable plates 13 is in a horizontal state again, the positioning assembly releases the positioning of the wire 4, which is convenient for the continuous guiding of the wire 4. The position of the movable roller 15 can be flexibly adjusted through the guide rod 17, the sliding seat 18 and the spring 19, which is convenient for the clamping of the wire 4.
