Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, and in particular to a 3D printing waste recycling device. Background Technology

[0002] With the rapid development and popularization of 3D printing technology, its applications in many fields are becoming increasingly widespread. However, this has also led to the generation of a large amount of 3D printing waste. This waste is mostly composed of polymer materials. Directly discarding it would not only result in a serious waste of valuable raw materials and increase the raw material costs of 3D printing production, but also, these polymer materials are difficult to degrade naturally, and long-term accumulation would pollute the environment, which is inconsistent with the industry trend of green production and sustainable development. Therefore, the recycling and reuse of 3D printing waste has become a critical issue that urgently needs to be addressed in the industry.

[0003] Currently, existing 3D printing waste recycling methods and related equipment in the industry still have many defects and shortcomings: First, most recycling devices are single-function, only possessing basic crushing capabilities and lacking a screening process synchronized with crushing. This results in uneven particle size of the crushed waste, which easily leads to uneven mixing of raw materials during subsequent remelting and granulation, directly affecting the quality of recycled products. Second, traditional crushing devices mostly adopt a single-crushing structure, with limited crushing force and efficiency, making it difficult to achieve sufficient crushing of waste. Often, multiple repeated crushing operations are required, which not only increases labor costs but also significantly reduces overall recycling efficiency. Third, the waste collection process lacks an effective monitoring and early warning mechanism. When waste accumulates to overflowing levels in the collection box, operators cannot be alerted in time to handle the situation, which can easily cause waste blockage, leading to equipment failure and interruption of the recycling process. Utility Model Content

[0004] To address some of the problems existing in the prior art, this utility model provides a 3D printing waste recycling device. This device is simple to operate and easy to maintain. It not only significantly improves the recycling efficiency and quality of 3D printing waste, but also reduces the waste of polymer raw materials and lowers the risk of environmental pollution. It has high practical value and promising prospects for industry promotion.

[0005] To achieve the above objectives, this utility model provides a 3D printing waste recycling device, comprising a device body, the device body including a box, a feeding crushing mechanism detachably mounted on the upper end of the box and its lower end connected to the interior of the box; a screening and rotary crushing mechanism fixedly disposed inside the box, the screening and rotary crushing mechanism corresponding to the feeding crushing mechanism; a first waste collection box disposed inside the feeding crushing mechanism, the first waste collection box being located directly above the screening and rotary crushing mechanism; a waste collection and discharge mechanism also disposed inside the box, one end of the waste collection and discharge mechanism being connected to the lower end of the screening and rotary crushing mechanism; a second waste collection box is disposed on one side of the box, the second waste collection box corresponding to the other end of the waste collection and discharge mechanism.

[0006] In operation, this invention first moves the cover plate of the feeding and crushing mechanism horizontally to open the upper opening of the crushing chamber, allowing 3D printing waste to be fed into the crushing chamber. Then, the drive motor on the connecting plate at the outer end of the crushing chamber is activated. The drive motor, through the drive gear assembly at the output end, drives multiple sets of crushing rollers inside the crushing chamber to rotate inwards and in opposite directions, performing preliminary crushing of the fed waste. Next, the pre-crushed waste falls through the crushing material discharge cylinder at the bottom of the crushing chamber into the first waste collection box. A filter screen in the annular groove on the inner side wall of the box performs preliminary filtration of the falling waste. Simultaneously, large particles of waste that do not pass through the filter screen remain in the first waste collection box. A first sensor monitors the waste accumulation height inside the box. The first waste collection box can be pulled out using a handle to remove the waste, and the filter screen can be cleaned or replaced. Then, the filtered waste that meets the preliminary requirements continues to fall into the first waste collection box. Inside the connecting hopper of the rotary crushing and screening mechanism, the fan blade drive motor on the outer mounting plate of the connecting hopper is started. The fan blade drive motor drives the rotating fan blades inside the connecting hopper to rotate via the transmission rod, further crushing the waste material and cooperating with the screening screen below the rotating fan blade assembly inside the connecting hopper to complete the screening. Unqualified waste material is further crushed by the rotating fan blade assembly, while qualified waste material enters the waste inlet of the waste collection and discharge mechanism through the connector at the lower end of the connecting hopper. Then, the drive assembly at one end of the waste conveying pipe is started. The drive assembly drives the spiral conveying rod inside the waste conveying pipe to rotate, conveying the waste material along the waste conveying pipe to the discharge port at the other end. Finally, the waste material is discharged from the discharge port and falls into the second waste collection box correspondingly set on one side of the box. The second sensor on the upper part of the inner side wall of the second waste collection box monitors the amount of waste material collected in the box in real time. At the same time, the operator can observe the working status inside the device through the transparent window on the side of the box.

[0007] The beneficial effects of this utility model are as follows: Firstly, the 3D printing waste is initially crushed using a feeding crushing mechanism. Then, a screening and rotary crushing mechanism is used to further crush and simultaneously screen the waste. This dual crushing design ensures thorough crushing of the waste, while the simultaneous screening function guarantees uniform particle size, providing high-quality raw materials for subsequent remelting and granulation processes. The removable filter screen inside the first waste collection box greatly facilitates subsequent cleaning and replacement, reducing maintenance difficulty. Simultaneously, the first and second sensors, respectively installed on the inner walls of the first and second waste collection boxes, enable real-time monitoring. The device measures the height of waste accumulation inside the box to issue timely warnings and prevent waste overflow, thus avoiding equipment blockage or malfunction. The waste collection and discharge mechanism uses a screw conveyor for waste transportation. Compared with traditional conveying methods, screw conveying ensures smooth movement of waste during transportation, significantly reducing material jamming and blockage, and ensuring the continuous and stable recycling process. In addition, the transparent window on the side of the box allows operators to observe the internal workings of the device in real time, promptly identify and handle abnormal problems. The feeding and crushing mechanism can easily open and close the opening at the top of the crushing chamber by the horizontal movement of the cover plate in the chute. The detachable design of each component and the convenient operation feature further enhance the practicality of the device.

A sliding groove is also provided on the top of the crushing chamber, and a cover plate is fitted inside the sliding groove. The cover plate can move horizontally within the sliding groove to open and close the upper opening of the crushing chamber.
