[0040] like Figures 1 to 7As shown, a wire extrusion device 100 for a 3D printer includes a main unit 1 and an extrusion mechanism 3, wherein the extrusion mechanism 3 includes a first movable member 32, a second movable member 33, a first clamping wheel 34, and a second clamping wheel 36, wherein the first movable member 32 or the second movable member 33 is movably arranged in the main unit 1; the first clamping wheel 34 is rotatably mounted on the first movable member 32, and the second clamping wheel 36 is rotatably mounted on the second movable member 33, and a processing position 38 is formed between the first clamping wheel 34 and the second clamping wheel 36; the first movable member 32 or the second movable member 33 has a first moving position and a second moving position, wherein in the first moving position, the first clamping wheel 34 and the second clamping wheel 36 are close to each other; and in the second moving position, the first clamping wheel 34 and the second clamping wheel 36 are far away from each other. A processing position 38 is formed between the first clamping wheel 34 and the second clamping wheel 36, and the wire passes through the processing position 38, and the first clamping wheel 34 and the second clamping wheel 36 cooperate with each other to achieve processing of the wire. Since the first clamping wheel 34 is installed on the first moving member 32, and the second clamping wheel 36 is installed on the second moving member 33, the first moving member 32 or the second moving member 33 has a first moving position and a second moving position. In the first moving position, the distance between the first clamping wheel 34 and the second clamping wheel 36 is closer, and the processing position 38 becomes smaller. In the second moving position, the distance between the first clamping wheel 34 and the second clamping wheel 36 is farther, and the processing position 38 becomes larger, so that the extrusion device 100 can process wires of different sizes at the processing position 38, thereby improving the problem that the existing extrusion device cannot integrate wires of different sizes.

[0041] like Figure 2 , Figure 3 , Figure 5 , Figure 6As shown, the extrusion mechanism 3 has a first driving component 31, which includes a first driving member 311, a screw rod 315, a first sliding block 316, a guide block 318, and a guide column 319. The first driving member 311 is installed on the main machine 1, and the screw rod 315 is installed on the output end of the first driving member 311. The first sliding block 316 is sleeved on the outside of the screw rod 315 and threadedly cooperates with the screw rod 315; the first end of the first moving member 32 or the second moving member 33 is installed on the first sliding block 316, and the second end of the first moving member 32 or the second moving member 33 is installed on the guide block 318. The guide column 319 is installed in the main machine 1 and is arranged parallel to the screw rod 315. The guide block 318 is sleeved on the outside of the guide column 319 and slidably cooperates with the guide column 319. In this embodiment, the first driving member 311 is used to drive the screw rod 315 to rotate. Since the first sliding block 316 is sleeved on the outside of the screw rod 315 and threadedly cooperates with the screw rod 315, and the two ends of the first movable member 32 are respectively fixed to the first sliding block 316 and the guide block 318, the guide block 318 is slidably cooperated with the guide column 319, and the guide block 318 is used to limit the rotation of the first movable member 32. Therefore, when the screw rod 315 rotates, a force is generated between it and the first sliding block 316. This force is used to drive the first sliding block 316 to move on the screw rod 315, thereby driving the first movable member 32 to move, and then driving the first clamping wheel 34 so that it has a first moving position and a second moving position, so that the first clamping wheel 34 adjusts the size of the processing position 38 when moving, and further realizes the processing of wires of different sizes on the processing position 38.

[0042] like Figure 2 , Figure 3 , Figure 5 As shown, the extrusion mechanism 3 also has a second sliding block 317, the first sliding block 316 and the second sliding block 317 are respectively sleeved on the two ends of the screw rod 315, and the screw rod 315 has a first external thread 3151 and a second external thread 3152, the thread directions of the first external thread 3151 and the second external thread 3152 are opposite, and the first sliding block 316 and the second sliding block 317 are both configured with internal threads that are threadedly matched with the first external thread 3151 and the second external thread 3152; the second sliding block 317 is installed on the second moving member 33, and the second moving member 33 is slidably matched with the guide column 319 through the guide block 318. In this embodiment, the first external thread 3151 is used to be threadedly connected with the internal thread of the first sliding block 316, and the second external thread 3152 is used to be threadedly connected with the internal thread of the second sliding block 317, and the thread directions of the first external thread 3151 and the second external thread 3152 are opposite. It can be seen that when the screw rod 315 rotates clockwise or counterclockwise, it will drive the first sliding block 316 and the second sliding block 317 to move closer to or away from each other, thereby further flexibly adjusting the size of the processing position 38.

[0043] like Figure 2 , Figure 3 , Figure 5 As shown, the extrusion mechanism 3 also has a first driving shaft 312, a first driving wheel 313, and a first driven wheel 314. The first driving shaft 312 is installed on the output end of the first driving member 311. The first driving wheel 313 is sleeved outside the first driving shaft 312. The first driven wheel 314 is sleeved outside the screw rod 315, and the first driving wheel 313 is meshed with the first driven wheel 314. In this embodiment, the first driving wheel 313 is meshed with the first driven wheel 314 to change the output torque and transmission ratio of the first driving shaft 312. The first driving wheel 313 and the first driven wheel 314 are equivalent to a speed reducer, which reduces the rotation speed of the screw rod 315, so that when the screw rod 315 rotates, it slowly drives the first clamping wheel 34 or the second clamping wheel 36 to move, so that the adjustment of the processing position 38 is more accurate.

[0044] like Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown, the extrusion mechanism 3 also has a first guide roller 37 and a heating plate 35.

After the extrusion is completed, the heat dissipation mechanism 4 is used to dissipate the heat of the extruded wire, and the wire is quickly cooled and cooled. The wire can then enter the water tank for water cooling, thereby improving the cooling efficiency of the wire and improving the cooling effect.

[0048] In addition, the first shell 13 also has a heat dissipation hole 131, and the heat dissipation hole 131 is used for air circulation inside and outside the first shell 13 to improve the heat dissipation efficiency in the first shell 13.

In this embodiment, the first shell 13, the second shell 14, and the third shell are all installed on the base 5, and the base 5 improves the stability of the first shell 13, the second shell 14, and the third shell.
