Technical Field

[0001] This utility model belongs to the field of alloy powder recycling technology, specifically an alloy powder recycling separator for additive manufacturing. Background Technology

[0002] Additive manufacturing, commonly known as 3D printing, is a technology that creates objects by layering materials based on three-dimensional model data. It can create objects with complex shapes and structures, breaking through the limitations of traditional manufacturing processes; it enables customized production to meet individual needs; the production process does not require molds, shortening the production cycle and reducing mold manufacturing costs; and it has high material utilization and reduces waste.

[0003] Alloy powder recycling separators are important components used in additive manufacturing processes to recycle and separate alloy powders. During use, alloy powders may exhibit uneven particle size distribution. Through specific structures and designs, recycling separators can separate powders of different particle sizes, allowing the qualified powders to continue to be used in additive manufacturing, while separating the unqualified coarse or fine powders for further processing or reprocessing.

[0004] In the existing technology, if there is too much alloy powder during the use of alloy powder recovery baffles, the thickness of the flowing alloy powder is large, resulting in a weak screening effect and making it difficult to separate the alloy powder.

[0005] Therefore, an alloy powder recycling baffle for additive manufacturing is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides an alloy powder recycling baffle for additive manufacturing, which has the advantages of allowing alloy powder to flow evenly on the uppermost screen to ensure screening effect, and the screen tilt angle is controllable, making it suitable for alloy powders of different particle sizes.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an alloy powder recycling partition for additive manufacturing, comprising a frame and a multi-layer screen disposed inside the frame, a material blocking component installed on the frame, and a tilt angle adjustment component connected to the frame;

[0008] The material blocking assembly includes a gantry, a screw threadedly connected to the gantry, and a material blocking plate connected to the bottom end of the screw via a bearing. The position of the material blocking plate corresponds to the uppermost screen. A positioning rod is fixedly connected to the material blocking plate, and the positioning rod passes through the gantry.

[0009] Preferably, the inner walls on both sides of the frame are provided with positioning grooves that match the screen, and the upper part of the frame is provided with a through groove corresponding to the screen. A handle is fixedly connected to one end of the screen near the through groove.

[0010] Preferably, the pore size of the filter holes on the multi-layered screen arranged from top to bottom decreases sequentially.

[0011] Preferably, the tilt angle adjustment assembly includes connecting bearings on both sides of the lower end of the frame, the connecting bearings are connected to a fixed vertical plate, the bottom of the fixed vertical plate is fixedly connected to a base frame, the upper end of the frame is equipped with a first rotating shaft, the first rotating shaft is connected to an electric telescopic rod, and the electric telescopic rod is connected to the base frame through a second rotating shaft.

[0012] Preferably, the lower end of the frame is fixedly connected to a plurality of extended guide plates corresponding to the screen, and the lengths of the plurality of extended guide plates decrease sequentially from top to bottom.

[0013] Preferably, a threaded hole is provided on the gantry at a position corresponding to the screw, the threaded hole is threaded to the screw, and a knob is fixedly connected to the top end of the screw.

[0014] Preferably, a positioning hole is provided on the gantry at a position corresponding to the positioning rod, and the positioning rod is disposed in the positioning hole.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model sets up a material blocking component to control the distance between the material blocking plate and the uppermost screen. If the flowing alloy powder is thick, it can be blocked, avoiding a large amount of alloy powder flowing on the uppermost screen, which would result in poor screening effect and facilitate the recovery of alloy powder.

[0017] 2. This utility model, by setting an inclination angle adjustment component, adjusts the inclination angle of the screen to control the flow speed of alloy powder, thereby making it suitable for screening alloy powders of different particle sizes and expanding the application range of alloy powder recycling baffles.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0029] like Figures 1 to 5 As shown, this utility model provides an alloy powder recycling partition for additive manufacturing, including a frame 1 and a multi-layer screen 2 disposed inside the frame 1. A material blocking component 3 is installed on the frame 1, and an tilt angle adjustment component 4 is connected to the frame 1.

[0030] The material blocking assembly 3 includes a gantry 301, with a screw 302 threadedly connected to the gantry 301. The bottom end of the screw 302 is connected to a material blocking plate 304 via a bearing 303. The position of the material blocking plate 304 corresponds to the uppermost screen 2. The material blocking plate 304 is fixedly connected to a positioning rod 305, which passes through the gantry 301 and controls the distance between the material blocking plate 304 and the uppermost screen 2. If the flowing alloy powder is thick, it can be blocked, preventing a large amount of alloy powder from flowing on the uppermost screen 2 and causing poor screening effect, which is beneficial to the recovery of alloy powder.

[0031] Specifically, the inner walls on both sides of the frame 1 are provided with positioning grooves 101 that match the screen 2, and the upper part of the frame 1 is provided with a through groove 102 that corresponds to the screen 2. A handle 5 is fixedly connected to one end of the screen 2 near the through groove 102.

[0032] Furthermore, the pore size of the filter holes on the multi-layered screen 2 arranged from top to bottom decreases sequentially.

[0033] Furthermore, the tilt angle adjustment component 4 includes connecting bearings 401 on both sides of the lower end of the frame 1. The connecting bearings 401 are connected to a fixed vertical plate 402. The bottom of the fixed vertical plate 402 is fixedly connected to a base frame 403. A first rotating shaft 404 is installed at the upper end of the frame 1. The first rotating shaft 404 is connected to an electric telescopic rod 405. The electric telescopic rod 405 is connected to the base frame 403 through a second rotating shaft 406. The tilt angle of the screen 2 is adjusted to control the flow speed of the alloy powder, thereby making it suitable for screening alloy powders of different particle sizes and expanding the application range of the alloy powder recovery partition.

[0034] It is worth noting that multiple extended guide plates 6 corresponding to the screen 2 are fixedly connected to the lower end of the frame 1. The length of the multiple extended guide plates 6 decreases sequentially from top to bottom, which facilitates the export of alloy powder from different screens 2.

[0035] It is worth noting that a threaded hole 306 is provided on the gantry 301 at the position corresponding to the screw 302. The threaded hole 306 is threadedly connected to the screw 302, and a knob 307 is fixedly connected to the top of the screw 302.

[0036] It is worth mentioning that a positioning hole 308 is provided on the gantry 301 at the position corresponding to the positioning rod 305, and the positioning rod 305 is located in the positioning hole 308.

[0037] The electric telescopic pole 405 is existing technology and will not be described in detail here. In addition, this utility model also includes a power supply, a controller and a switch, which are not the main technical points of this patent and will not be described in detail here.

[0038] Working principle and process: Activating the electric telescopic rod 405 of the tilt angle adjustment component 4 causes the electric telescopic rod 405 to extend or shorten, thereby causing the frame 1 to rotate around the connecting bearing 401 to adjust the tilt angle of the frame 1 and the screen 2. Different tilt angles can be adjusted according to the particle size range of the alloy powder to be screened, thereby controlling the flow rate. The alloy powder to be screened is placed at the upper end of the screen 2. Under the action of gravity, the alloy powder will flow. Rotating the knob 307 of the material blocking component 3 causes the screw 302 to rotate. Under the action of the screw and the positioning rod 305, the material blocking plate 304 moves up or down, controlling the distance between the material blocking plate 304 and the uppermost screen 2. If the flowing alloy powder is thick, it can be blocked, preventing a large amount of alloy powder from flowing on the uppermost screen 2, which would result in poor screening effect and facilitate the recovery of alloy powder. The screened alloy powder will be discharged along the extended guide plate 6 for collection.
