Description

Technical Field

[0001] This invention relates to the field of 3D printing technology, and more specifically to a convenient 3D printing consumable recycling device. Background Technology

[0002] 3D printing, also known as additive manufacturing, is a rapid prototyping technology. It is a technique that uses digital model files as a basis and employs powdered metal or plastic and other bondable materials to construct objects layer by layer. During the 3D printing process, defective or waste products may be generated for various reasons. These defective products cannot meet the requirements and must be recycled. They are then restored to the consumables used in 3D printing through specified methods, thereby reducing the waste of consumables.

[0003] Current methods for recycling defective 3D printed products generally involve crushing them before uniform processing. This improves processing efficiency and standardizes the shape of the defective products, preventing oddly shaped defective products from taking up too much space and causing transportation difficulties.

[0004] When existing crushing machines crush or grind defective products, some large fragments are produced. These fragments also occupy a lot of space. Workers usually throw them back into the crushing equipment for further crushing. However, this requires workers to continuously monitor the operation of the crushing machine, which increases the consumption of manpower. In view of this, the present invention proposes a convenient 3D printing consumable recycling device. Summary of the Invention

[0021] Beneficial effects

[0022] The technical solution provided by this invention has the following advantages compared with known public technologies:

[0023] 1. This invention is equipped with a lifting seat. By driving the lifting seat through a driving mechanism, this device can intermittently transport 3D printing consumable fragments larger than the standard size accumulated on the filter plate back to the upper part of the cavity, where they can then be re-crushed. This not only helps to crush the 3D printing consumable fragments into the same size, facilitating their transportation and subsequent processing by staff, but also greatly improves the ease of operation of this device. It is an ingenious design.

[0024] 2. The present invention is provided with an extrusion block, on which a triangular groove is formed. The triangular groove can destroy the integrity of the surface of the 3D printing material, thereby making it easier and faster for the extrusion block to crush the 3D printing material into small pieces through extrusion.

[0025] 3. The present invention is equipped with a filter plate, a connecting rod and a fixing block. The filter plate can swing by rotating the connecting rod through the rotating column. This not only transports large pieces of 3D printing consumables to the through port, making it easy for the lifting seat to transport them back to the feed port, but also prevents the pieces of 3D printing consumables from getting stuck in the holes of the filter plate and causing blockage.

Multiple tension springs 38 are fixed between the rear top surface of the movable door 36 and the top surface of the door groove 37.

[0042] A drive mechanism 11 is provided on one side of the outer casing 2. The drive mechanism 11 drives the lifting seat 8 to move up and down. The drive mechanism 11 includes a motor 23, which is fixed to one side of the outer casing 2. The output end of the motor 23 extends through the side wall of the outer casing 2 into the cavity 3 and is coaxially fixedly connected to the rear rotating column 14. The two rotating columns 14 are coaxially fixedly connected to the ends near the motor 23 with first gears 24, and the two first gears 24 are meshed. A side groove 25 is provided in the interlayer of the outer wall on the side of the outer casing 2 away from the motor 23. Two symmetrically arranged side grooves are provided inside the side groove 25. The second gear 26 is connected to the outer wall of the second gear 26 by a transmission belt 27. The inner wall of the transmission belt 27 has a toothed groove 28 that meshes with the second gear 26. The lower end of the outer wall of the transmission belt 27 is fixedly provided with a transition seat 29. A slide rod 30 is rotatably connected inside the transition seat 29. The rear wall of the side groove 25 has a through groove 31 that slides with the slide rod 30. The through groove 31 connects the side groove 25 and the vertical groove 6. The side wall of the lifting seat 8 has a sliding groove 32 at the position opposite to the slide rod 30. Both the slide rod 30 and the sliding groove 32 are T-shaped structures and slide with each other.

[0043] Working principle: The staff can collect the defective products generated by 3D printing or the scraps generated during the processing of 3D printed products, and then put them into this device through the feed port 5. At this time, the staff can start the motor 23 to drive the crushing mechanism 4 to operate. When the rotating column 14 located at the rear rotates, it will drive the rotating column 14 to rotate together through the two first gears 24, thereby causing the two rotating columns 14 to rotate in opposite directions. The multiple extrusion blocks 16 on the two columns will crush the 3D printing consumables. The triangular grooves 17 on the extrusion blocks 16 can also pierce the outer wall of the 3D printing consumables, so that the surface of the 3D printing consumables is no longer a whole, and thus it is easier to be crushed by the extrusion blocks 16.

[0044] The broken 3D printing filament falls onto the top surface of the filter plate 20 in the outlet 13. Fragments that meet specifications pass through the filter plate 20 and fall into the storage box 12 below, while those that do not meet the requirements are intercepted by the filter plate 20. Simultaneously, as the front rotating column 14 rotates, the upper end of the connecting rod 18, which is eccentrically connected to it, rotates. Because its lower end is rotatably connected to the fixed block 21, the lower end of the connecting rod 18 drives the filter plate 20 through the fixed block 21. Since the rear end of the filter plate 20 is rotatably connected to the outlet 13, the filter plate 20 only moves along the rotating connection under the influence of the rotating column 14. The position swings, and the rear wall of the limiting block 22 on the rear side of the filter plate 20 is an arc surface structure. This arc surface is also centered on the rotational connection position between the filter plate 20 and the discharge port 13. Therefore, during the swing, the limiting block 22 can always seal the rear of the filter plate 20, so that the 3D printing consumable fragments with unqualified dimensions on the filter plate 20 will not fall out from the rear of the filter plate 20. During the swing, the 3D printing consumable fragments will move forward continuously and be put into the lower through port 7. Then, the lifting seat 8 can transport these unqualified 3D printing consumable fragments back into the feed port 5. In addition, such swing can also prevent the filter plate 20 from clogging, achieving two goals at once.

[0045] On the other hand, when the lifting seat 8 has not moved to the lower end of the vertical groove 6, the movable door 36 will block the bottommost through-hole 7 under the action of the tension spring 38. Oversized 3D printing filament fragments will concentrate in front of the movable door 36. When the lifting seat 8 moves to the lower part, its bottom surface will push the movable door 36 downwards and open the bottommost through-hole 7. Then, the 3D printing filament fragments will fall onto the rotating plate 9 from the bottommost through-hole 7. During the subsequent retraction of the lifting seat 8, the rotating plate 9, due to the constraint of the coil spring 35, will remain in a tilted state with the front higher than the back. The fragments accumulate at the angle between the inner wall of the rotating plate 9 and the lifting seat 8. When the rotating plate 9 moves above the vertical groove 6 with the lifting seat 8, the extrusion rod 10 will cause the front end of the rotating plate 9 to deflect downward by extruding the front part of the rotating plate 9, eventually forming an inclined state with the front lower and the back higher. When the rotating plate 9 starts to tilt, its end is already aligned with the bottom surface of the upper through-hole 7. Therefore, 3D printing material fragments larger than the specified particle size will return to the feed port 5 from the upper through-hole 7 and be crushed a second time through the device. This can effectively improve the crushing effect and avoid the time and effort of manually supervising the operation of the device.

[0046] The lifting seat 8 is raised by the drive mechanism 11. The upper second gear 26 in the drive mechanism 11 rotates together with the rear rotating column 14. Then, in cooperation with the lower second gear 26, it drives the transmission belt 27 to rotate. In this way, the adapter seat 29 rotates. The slide rod 30 rotatably connected to it is slidably connected to the lifting seat 8 at its end. Therefore, the length of the slide rod 30 in front of the lifting seat 8 is variable. This allows the rotation of the adapter seat 29 to drive the lifting seat 8 to move up and down reciprocally. In this way, non-compliant 3D printing material fragments in the cavity 3 can be collected and transported intermittently.

[0047] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
