[0026] With the rapid development of 3D printing technology, its applications in many fields such as industrial design, education, and medical treatment are becoming increasingly widespread. However, during the 3D printing process, especially when using meltable materials such as plastics and resins, a large amount of unutilized or wasted materials (i.e., waste materials) will be generated. Currently, these waste materials are often regarded as useless waste and are sent to landfills or incinerators for treatment, which not only wastes resources but also burdens the environment.

[0027] Therefore, the design concept of this application is to reprocess and mold recyclable molten waste, and through steps such as hot melting and plastic shaping, the waste materials are recycled for the second time to produce 3D printer recycled consumables, which not only saves resources, reduces the use cost, but also effectively avoids environmental pollution.

[0028] As Figure 1 shown, this application provides a 3D printer waste recycling device, including a workbench, on which a bracket is provided, a stirring mechanism is provided on the bracket, the stirring mechanism is connected to a hot melting and shaping mechanism, the hot melting and shaping mechanism is connected to an extrusion mechanism, and a winding mechanism is provided below the extrusion mechanism.

[0029] Among them, the bracket includes a vertical frame 1, a lower left horizontal frame 2 and an upper right horizontal frame 3. During use, the vertical frame 1, the lower left horizontal frame 2 and the upper right horizontal frame 3 are used to install other components.

[0030] Among them, the stirring mechanism includes a hopper 4 located above the vertical frame 1. An inverted U-shaped frame is provided at the edge of the hopper 4. The inverted U-shaped frame is connected to an upper stepping motor 5. The upper stepping motor 5 is connected to an upper speed reducer 6. The upper speed reducer 6 is connected to a stirring paddle 7. The inverted U-shaped frame is welded across the upper part of the hopper 4 at the edge of the hopper 4. When the upper stepping motor 5 and the upper speed reducer 6 are started, they drive the stirring paddle 7 to rotate, stirring the materials in the hopper 4.

[0031] Among them, the hot melting and shaping mechanism includes a hot melting cylinder 8 provided on the vertical frame 1, a screw rod located inside the hot melting cylinder 8, and a shaping tube 9 communicated with the bottom of the hot melting cylinder 8. A heating plate or heating wire is provided on the inner wall of the hot melting cylinder 8. The screw rod is connected to the bottom of the stirring paddle 7. The shaping tube 9 is communicated with the extrusion mechanism.

[0032] The heating plate or heating wire heats the materials. After the materials are melted, they flow downward. The screw rod rotates driven by the rotating stirring paddle 7, mixing the uniformly melted materials and driving the materials to move downward until they flow into the shaping tube 9. The shaping tube 9 is made of copper and graphene tubes with excellent heat dissipation effects. The melted materials slowly solidify into linear consumables (consumable wires) in the shaping tube 9.

[0033] Among them, the extrusion mechanism includes a double gear extruder 10 provided on the upper right horizontal frame 3. The double gear extruder 10 is communicated with a guiding tube 11. The guiding tube 11 is connected to a square frame 12. The square frame 12 is provided on the lower left horizontal frame 2.

[0034] The double-gear extruder 10 provides continuous moving power for the linear consumables. The guiding tube 11 is also made of copper and graphene tubes with excellent heat dissipation effect. The linear consumables with remaining heat are cooled again to strengthen the shaping. A connecting tube is arranged at the bottom of the square frame 12. The guiding tube 11 is communicated with the connecting tube. The linear consumables led out from the guiding tube 11 pass through the connecting tube and are wound around the reel 13.

[0035] Among them, the winding mechanism includes a reel 13, and the reel 13 is connected with a lower stepping motor 14; during use, the lower stepping motor 14 provides rotational power for the reel 13.

[0036] Among them, a cooling fan 15 is arranged below the hot melt forming mechanism; the cooling fan 15 accelerates the air flow around the device and cools the linear consumables better.

[0037] When using this application, when unnecessary support materials or wastes are generated during 3D printing, these wastes will first be crushed by a small crusher. The fine particles after crushing are poured into the hopper 4 of the recycling device. The upper stepping motor 5 and the upper speed reducer 6 are started to drive the stirring paddle 7 to rotate and stir the materials in the mixing hopper 4. The mixed materials enter the hot melt cylinder 8 and are heated to a molten state in the hot melt cylinder 8. The molten materials slowly solidify into linear consumables (consumable wires) in the forming tube 9, and then are conveyed to the double-gear extruder 10. The double-gear extruder 10 provides continuous moving power for the linear consumables. The linear consumables led out from the guiding tube 11 pass through the connecting tube and are wound around the reel 13 waiting to be used. The cooling fan 15 is always started to accelerate the air flow around the device. In this way, the entire recycling cycle is completed, realizing the recycling of resources and effectively reducing the consumption of raw materials.
