[0001] This utility model belongs to the technical field of 3D printing, specifically relating to a titanium alloy 3D printing device with automatic powder recycling function. Background Technology

[0002] Titanium alloy 3D printing equipment is an additive manufacturing device that uses high-energy beams such as lasers or electron beams as heat sources to achieve near-net-shape forming of complex components by melting titanium alloy powder layer by layer. Its core components include a precision powder placement system, an inert gas protective chamber, a high-power laser / electron beam generator, and a numerical control module. During operation, the energy beam is controlled by CAD model slicing data to selectively melt powder layers, which are then cyclically deposited until a three-dimensional solid is completed.

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0018] Example Reference Figures 1-5 This embodiment of the present invention provides a titanium alloy 3D printing device with automatic powder recycling function, comprising: The supporting structure 100 includes the isolation box 110; The recycling mechanism 200 includes a support base 210 fixedly installed in the inner cavity of the isolation box 110 near the bottom, a gravity collection component 220 disposed in the inner cavity of the support base 210, and a manual extraction component 230 disposed in the inner cavity of the isolation box 110 for use with the gravity collection component 220.

[0019] The isolation box 110 creates a closed working environment, effectively isolating external pollution and ensuring operational safety. The collaborative design of the support base 210 and the gravity collection component 220 enables the primary automated recycling of unmelted powder, reducing manual intervention. The manual extraction component 230 serves as an auxiliary recycling unit, providing redundancy in case of gravity recycling failure, thus ensuring powder recovery rate.

[0020] Specifically, the recycling mechanism 200 also includes an inclined base plate 240 fixedly installed on the top of the support base 210, a filter grid 250 fixedly installed on the top of the inclined base plate 240, a guide slope 260 fixedly installed on the top of the inclined base plate 240, a storage tank 270 fixedly installed on the outside of the isolation box 110, and a connecting pipe 280 fixedly installed at the bottom of the storage tank 270.

[0021] The inclined bottom plate 240, together with the guide slope 260, forms a directional powder flow path, which improves the recovery efficiency by utilizing gravity. The filter grid 250 pre-screens the powder to intercept large-sized impurities. The storage tank 270 achieves centralized storage of the recovered powder through the connecting pipe 280, avoiding secondary pollution and reducing the powder residue rate, without relying on power components.

[0022] Furthermore, the gravity collection assembly 220 includes a collection chamber 221 that is movably mounted in the inner cavity of the support base 210, and a communication slot 222 opened on the top of the collection chamber 221. The gravity collection assembly 220 also includes a pull-out plate 223 fixedly installed on the outside of the collection chamber 221, and a sealing strip 224 fixedly installed on the top of the collection chamber 221.

[0023] The collection chamber 221 features a detachable structure for easy maintenance and cleaning. The connecting slot 222 ensures that the powder falls efficiently into the collection area, preventing accumulation and blockage. The modular design enables quick assembly and disassembly. The addition of a sealing strip 224 further prevents powder from escaping, meeting the damage prevention requirements of high-value titanium powder. The pull-out plate 223 extends to the outside of the isolation box 110, allowing the operator to remove and place the collection chamber 221 without opening the box, reducing the risk of damage from the inert gas environment. The sealing strip 224 fits tightly against the inner wall of the box, forming a dynamic sealing barrier that effectively inhibits the oxidation of titanium powder caused by oxygen infiltration.

[0024] Preferably, the manual extraction assembly 230 includes a cylinder 231 fixedly installed inside the cavity of the isolation box 110, a piston rod 232 movably sleeved inside the cavity of the cylinder 231, and a valve plate 233 fixedly installed at one end of the piston rod 232. The manual extraction assembly 230 also includes a pull rod 234 fixedly installed at the other end of the piston rod 232, and a delivery hose 235 fixedly installed at the bottom of the cylinder 231. One end of the delivery hose 235 is fixedly connected to the end of the connecting pipe 280 and they are interconnected.

[0025] The cylinder 231 and piston rod 232 form a negative pressure extraction mechanism, which can perform directional recovery of residual powder in dead corners. The valve plate 233 realizes unidirectional airflow control to prevent powder backflow. The purely mechanical structure can still maintain basic recovery function under abnormal working conditions such as power failure. The pull rod 234 provides a labor-saving operation fulcrum to reduce the intensity of manual extraction. The flexible connection design of the conveying hose 235 adapts to different installation angles to ensure smooth delivery of powder to the storage tank 270.

[0026] Furthermore, the support mechanism 100 also includes a sealed door 120 hinged to the outside of the isolation box 110, and an adjustable printer 130 disposed inside the isolation box 110 for 3D printing.

[0027] The sealed door 120 adopts a hinged structure to facilitate equipment maintenance. When closed, it forms a complete seal with the isolation box 110. The independent layout of the adjustable printer 130 avoids motion interference with the recycling mechanism 200.

[0028] During use, after printing, the unmelted titanium alloy powder first slides down from the inclined base plate 240 under gravity, and is guided by the guide slope 260 to the filter grid 250 for primary screening. The qualified powder after screening enters the chamber through the connecting slot 222 of the collection chamber 221 for automatic collection. The residual powder is manually extracted by the operator through the pull rod 234 using the manual extraction component 230. The negative pressure generated by the piston rod 232 is used to draw it into the storage tank 270 through the conveying hose 235. The entire recycling process is carried out in the sealed environment of the isolation box 110. The operator can easily remove the collection chamber 221 for cleaning through the pull plate 223. The design of the sealed door 120 and the sealing strip 224 effectively maintains the inert gas environment inside the box, ensuring that the titanium powder is not oxidized and contaminated during the recycling process. The printer 130 operates independently during printing and recycling without interference.

[0029] In summary, the closed structure formed by the isolation chamber 110 and the sealed door 120 effectively prevents titanium powder oxidation pollution and dust diffusion, ensuring operational safety. The gravity collection component 220, combined with the inclined bottom plate 240 and the filter grid 250, realizes automatic powder screening and recovery, improving recovery efficiency and reducing manual intervention. The manual extraction component 230 provides reliable redundancy for the system, ensuring the integrity of powder recovery. The collection chamber 221 is designed with a sealing strip 224 to ensure a stable inert gas environment while facilitating maintenance.
