Description

Technical Field

[0001] This invention relates to the field of 3D printer technology, specifically to a toner recycling device for 3D printing. Background Technology

[0002] A 3D printer is a device that creates three-dimensional objects by depositing materials layer by layer. It is widely used in fields such as industrial design, medicine, education, architecture, and aerospace.

[0003] Dentures (also known as prostheses) are artificial restorations used to replace missing natural teeth, designed to restore chewing function, speech clarity, and facial aesthetics. Depending on the extent of restoration and design, dentures can be classified into several types.

[0004] Currently, existing metal denture 3D printers suffer from several drawbacks during operation. Metal powder is scattered and blown up during molding, resulting in a significant accumulation at the bottom of the printer's internal cavity. Furthermore, the relatively small internal space of the 3D printer, coupled with the clumping of some incompletely melted metal powder, hinders the removal of remaining powder. Consequently, existing metal denture 3D printers are unable to perform uniform sieving and centralized collection of metal powder during use. Therefore, an improved device is needed to address these issues. Summary of the Invention

[0023] The beneficial effects of this invention are:

[0024] First, this invention uses an alignment cavity located at the bottom of the 3D printer's interior. This allows falling metal powder to slide onto the alignment cavity via a guide partition. The alignment cavity isolates clumps of metal powder, facilitating the recovery of finer metal powder. Simultaneously, a lifting plate can intermittently move up and down at the bottom of the alignment cavity, allowing it to rotate. This enables the metal powder to roll inside the alignment cavity, improving the sieving efficiency and achieving uniform sieving of the metal powder.

[0025] Second, this invention uses the intermittent displacement of the displacement crossbeam inside the transfer cavity to allow the impact head to intermittently strike the bottom of the guide partition, thereby preventing metal powder from accumulating on the surface of the guide partition. At the same time, during displacement, the displacement crossbeam can drive the displacement vertical rod and the actuating crossbeam to move inside the accumulation cavity via the L-shaped connecting rod, allowing the actuating crossbeam to sweep horizontally inside the accumulation cavity, preventing metal powder from accumulating in a localized area at the bottom of the accumulation cavity, thus completing the work of centralized collection of metal powder.

With the setting of the second return spring 38, the displacement vertical rod 36 can be driven to return to its original position when it is not under pressure.

[0053] The alignment cavity 9 is slidably inserted into the interior of the transfer cavity 29. The transmission cavity 33 is fixedly installed at the top of the transfer cavity 29, and the transfer cavity 29 is fixedly installed at the bottom of the 3D printer 4. The L-shaped connecting rod 30 is fixedly installed at the rear end of the displacement crossbeam 16. The accumulation cavity 39 is slidably inserted into the rear end of the transmission cavity 33. The inner sides of the guide cavity 32 are inclined at 45°. Movable grooves are opened at both ends of the top of the transmission cavity 33. A groove is opened at the front end of the top of the accumulation cavity 39. An L-shaped wedge is opened at the front end of the displacement vertical rod 36. The 3D printer 4... The bottom of the base 6 has a through hole, and the bottom of the base 6 and the surface of the support crossbar 5 are provided with matching mounting grooves. The alignment cavity 9 is aligned with the bottom of the 3D printer 4. The impact head 22 is vertically aligned with the bottom of the guide partition 42. The top of the transmission base plate 19 is symmetrically fixed with racks. The L-shaped air cylinder 27 is hollow inside, and a sealed cavity is formed between the second piston rod 28, the L-shaped air cylinder 27 and the first piston rod 17. The bottom of the displacement crossbar 16 is attached to the bottom of the transfer cavity 29. The bottom of the transfer cavity 29 is provided with a discharge hole.

[0054] The working principle of Example 1 is as follows: During use, metal powder is evenly spread on the surface of the base. Then, the high-energy laser inside the 3D printer 4 selectively melts the metal powder according to the slicing path until the metal powder is layered and formed, completing the preparation of the metal denture. At this time, a through hole is opened at the bottom of the 3D printer 4, allowing the metal powder falling from the part to enter the surface of the guide partition 42 and the interior of the alignment cavity 9 through the through hole. The guide partition 42 is set at a 45° angle, allowing the metal powder to slide along the surface of the guide partition 42 and fall into the interior of the alignment cavity 9. A sieve is installed at the bottom of the interior of the alignment cavity 9, allowing the metal powder to be concentrated and sieved inside the alignment cavity 9. At this time, the incompletely melted and clumped metal powder is separated. The powder can be isolated by the alignment cavity 9, while smaller metal powders can fall through the alignment cavity 9 into the accumulation cavity 39 for storage. Simultaneously, the micro motor 14 can be turned on, driving the lead screw 15 to rotate. The displacement crossarm 16 is threaded onto the outer ring of the lead screw 15, allowing the lead screw 15 to drive the displacement crossarm 16 to move rearward. When the displacement crossarm 16 moves rearward, it causes the teeth on the transmission base plate 19 to pass the bottom end of the transmission gear 20. This causes the transmission gear 20 to drive the take-up wheel 18 to pull the impact head 22 downward, creating a gap between the impact head 22 and the bottom end of the guide partition 42. Subsequently, when the teeth on the transmission base plate 19 pass the transmission gear 20, the transmission gear 20 loses its meshing force. At this point, the... The elasticity of the return spring 24 causes the impact head 22 to move upward rapidly, allowing it to quickly impact the guide partition 42. This vibrates and dislodges the metal powder accumulated on the surface of the guide partition 42, preventing its accumulation. Subsequently, when the displacement crossbeam 16 moves to its extreme rear position, it drives the two racks on the transmission base plate 19 to pass through the bottom of the transmission gear 20, thus impacting the guide partition 42 twice and improving the discharge efficiency of the metal powder. Simultaneously, when the displacement crossbeam 16 moves to contact the first piston rod 17, it squeezes the first piston rod 17 into the interior of the L-shaped air cylinder 27, thereby driving the second piston rod 28 and the lifting plate 26 to move upward. This is maintained by the alignment cavity 9. The alignment chamber 9 is tilted downwards at a 20° angle, allowing metal powder to accumulate at the lower end. When the lifting plate 26 moves upwards, it pushes the bottom of the alignment chamber 9 upwards, causing the swing arm 10 to rotate and connect to the support frame 11. This allows the swing arm 10 to rotate upwards with the support frame 11 as the base point, enabling the metal powder inside the alignment chamber 9 to roll back and forth, improving the filtration efficiency of the metal powder. Simultaneously, when the displacement crossbar 16 moves, it also drives the L-shaped connecting rod 30 and the contact rod 31 to move. The bottom rear end of the contact rod 31 contacts the L-shaped wedge inside the front end of the displacement vertical rod 36, causing the L-shaped connecting rod 30 to move backwards, pushing the displacement vertical rod 36 and the toggle crossbar 35 to move within the accumulation chamber 39.When the lever 35 moves past the metal powder accumulated at the bottom of the accumulation cavity 39, the higher-pile metal powder can be pushed down by the lever 35, preventing the metal powder from accumulating too high. Subsequently, when the micro motor 14 is turned on and drives the lead screw 15 to rotate in the opposite direction, the displacement crossbar 16 can move forward, so that the L-shaped connecting rod 30 can drive the contact rod 31 to move forward. Thus, the second reset spring 38 can drive the displacement vertical rod 36 to move forward and reset. The displacement vertical rod 36 is slidably sleeved on the outer ring of the guide rod 37, so that the displacement vertical rod 36 can be supported to move in a straight line. Furthermore, when the displacement crossbar 16 drives the transmission base plate 19 to move forward, it can drive the two racks to pass the bottom of the transmission gear 20 again, so that the impact head 22 can impact the guide partition 42 again, improving the efficiency of the guide partition 42 in conveying metal powder. Furthermore, when the displacement crossbar 16 moves to the first piston rod When the first piston rod 17 disengages, it can tilt downwards from its normal position, allowing the lifting plate 26 to move downwards. This enables the second piston rod 28 to enter the L-shaped air cylinder 27, and the first piston rod 17 to move forward and reset, facilitating the re-engagement of the displacement crossbeam 16 with the first piston rod 17. Furthermore, when the first piston rod 17 rotates downwards to its limit position, it contacts the top of the limiting base plate 12, preventing excessive rotation of the first piston rod 17 and ensuring it is tilted for metal powder sieving. When excessive agglomerated powder accumulates inside the first piston rod 17, the bolts on the push plate 13 and the transfer chamber 29 can be removed, and the push plate 13 can be pulled backwards until the first piston rod 17 is extracted from the transfer chamber 29, allowing for the removal of the accumulated powder and completing the process.

[0055] Example 2

[0056] Based on Example 1, such as Figure 10 As shown, the support crossbar 5 includes a positioning insert 40 and a limiting side plate 41. The limiting side plate 41 is symmetrically fixedly installed at the top of the support crossbar 5, and the positioning insert 40 is slidably inserted into the side end of the limiting side plate 41.

[0057] In implementing this embodiment, when the base 6 is installed at the top of the support crossbar 5, the base 6 has round holes on both sides, and the round holes are horizontally aligned with the positioning rod 40. The positioning rod 40 can be inserted through the limiting side plate 41 into the round hole inside the base 6, which can stably limit the base 6 to the top of the support crossbar 5 and prevent the base 6 from sliding during 3D printing, thus completing the work.
