Description

Technical Field

[0002] 3D printing, also known as additive manufacturing technology, is a technology that manufactures solid parts by adding materials layer by layer based on three-dimensional CAD data. It is now not only used in industrial design, model making and prototyping, but also beginning to penetrate into fields such as medical, aerospace, automotive and construction. The raw materials for 3D printing include various resin composite materials, and 3D printers generate waste materials during operation.

[0003] Traditional 3D printer waste is typically placed directly into a recycling bin. Because the waste is fluffy, direct placement takes up considerable space, increasing the frequency of bin cleaning. To overcome these drawbacks, existing technology (Chinese patent application number 202223004445.6, application date 2022-11-11) describes a 3D printer waste recycling device. This device, through a crushing mechanism, drive motor, and collection bin, can crush and collect the waste, effectively reducing space requirements and cleaning frequency. The elastic sealing mechanism automatically seals the feed hole after waste is placed in, reducing waste debris escaping during crushing and minimizing environmental pollution. However, this device only achieves preliminary waste recycling. If reuse is required, additional processing steps are needed, leading to cumbersome operation, hindering waste recycling, and resulting in low efficiency.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on existing equipment. Therefore, we have proposed a material recycling device for 3D printing equipment that can effectively solve these problems. Utility Model Content

[0015] (3) By setting up a wire drawing assembly, the wire drawing motor drives the active rotating shaft to rotate.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figures 1-6 This utility model provides the following technical solution: a material recycling device for 3D printing equipment, comprising a collection box 3 fixedly installed on the top of the operating table 1 via a fixing frame 2, and the collection box 3 receiving the waste inlet of the 3D printing equipment; a reshaping assembly is provided at the bottom of the collection box 3, the reshaping assembly including a hot melt channel 4, a curing channel 5, and an extrusion head 6 sequentially fixedly connected to the bottom of the collection box 3, and the hot melt channel 4, the curing channel 5, and the extrusion head 6 successively narrowing downwards, and heating pipes and condensing pipes are respectively laid inside the hot melt channel 4 and the curing channel 5. The inside of the collection box 3 is equipped with a feeding motor 7. The bottom output shaft of the feeding motor 7 is fixedly connected to a conveying shaft 8, and the outer wall of the conveying shaft 8 is fixedly connected to a conveying blade 9. The conveying shaft 8 and the conveying blade 9 are located inside the hot melt channel 4. The bottom inner sides of the collection box 3 and the hot melt channel 4 are both fixedly connected to support frames, and the feeding motor 7 and the conveying shaft 8 are securely installed inside the hot melt channel 4 through these two support frames. A wire drawing assembly is also provided below the extrusion head 6, which is used to draw and rewind the waste material extruded from the extrusion head 6.

[0026] By using the reshaping component and the wire drawing component together, during use, the collection box 3 receives the waste material falling from the waste port of the 3D printing equipment. At the same time, the feeding motor 7 starts and drives the conveyor shaft 8 and the conveyor blades 9 to rotate. The conveyor blades 9 will continue to convey the waste material downwards. The waste material passes through the hot melting channel 4 and is melted into a flowing liquid by the heating tube. The waste liquid continues to flow downwards and is solidified by the condenser tube through the solidification channel 5. Finally, it is extruded into filaments through the narrow extrusion head 6 and discharged. Then, the wire drawing component will further draw and rewind the filaments for reuse. The above structure is compact and reasonable, which can effectively convert waste material into filaments for recycling without the need for additional processing steps. The operation is fast and convenient, improving the recycling efficiency.

[0027] Furthermore, a condenser 11 is installed on the top of the operating table 1 via a heightening bracket. Water pipes 10 are fixedly connected to the input and output ends of the condenser 11, and the two water pipes 10 are respectively inserted into the bottom and top ports of the curing channel 5. Through the coordinated use of the curing channel 5, water pipes 10, and condenser 11, the condenser 11 is used to condense the water and output it to the top port of the curing channel 5 through the water pipes 10. The water continues to spiral down around the curing channel 5 to condense and fix the waste liquid flowing through the inside of the curing channel 5. Then the water is transported back to the condenser 11 from the bottom port through the water pipes 10 for re-condensation to achieve a highly efficient condensation and fixing effect.

[0028] Example 2: Based on Example 1, the wire drawing assembly includes a wire drawing motor 12 fixedly installed on the top of the operating table 1. A drive shaft 13 is fixedly connected to the output end of the wire drawing motor 12, and a wire drawing shaft 14 is sleeved on the outer side of the drive shaft 13. The outer wall of the drive shaft 13 has a protruding strip, and the inner wall of the wire drawing shaft 14 has a groove. The protruding strip slides within the groove to achieve axial positioning of the drive shaft 13 and the wire drawing shaft 14, allowing the drive shaft 13 to be driven by the wire drawing motor 12 to synchronously rotate the wire drawing shaft 14. Located directly below the extrusion head 6, the top of the operating table 1 is movably equipped with a mounting base 17, and the end of the drawing shaft 14 is rotatably mounted on the inner side of the mounting base 17. By setting up the drawing assembly, the drawing motor 12 drives the active shaft 13 to rotate, and the drawing shaft 14 rotates synchronously, which can receive the filamentous consumables extruded from the extrusion head 6 and wind them up on the outside. When it is needed, the mounting base 17 is moved away from the drawing motor 12 to drive the drawing shaft 14 to come off from one side of the active shaft 13 for recycling.

A protruding plate is formed on the top of the mounting base 17, and the limiting plate 18 is fixedly connected to the protruding plate by bolt fasteners 19. The bolt fasteners 19 further secure the limiting plate 18 to the mounting base. By fixing the convex plate on 17, the wire drawing shaft 14 can be stably installed inside the mounting base 17. When the wire drawing shaft 14 needs to be removed, the electric slide table 16 is started to move along the slide rail 15 away from the wire drawing motor 12. The mounting base 17 can then drive the wire drawing shaft 14 to disengage from the active shaft 13. Then, simply unscrew the bolt fastener 19 and pull the limiting plate 18 outward to expose the opening of the mounting base 17. The wire drawing shaft 14 can then be taken out from the opening for use.
