Description

Technical Field

[0001] This utility model relates to the field of metal 3D printing auxiliary equipment technology, and in particular to a recycling device for improving the utilization rate of metal 3D printing powder. Background Technology

[0002] Metal 3D printing technology, with its advantage in forming complex structures, is widely used in aerospace, medical implants and other fields. This technology requires metal powder as raw material and achieves forming through a cyclic process of powder spreading and melting. However, after each printing, 30% to 40% of unmelted residual powder is generated around the forming platform. Due to the lack of a stable collection structure, the residual powder is easily scattered into the gaps between the equipment or on the ground, with a recovery rate of less than 60%. Furthermore, the scattered powder easily attracts dust and oil, leading to a decrease in powder utilization.

[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: residual powder after metal 3D printing will fall from the main body of the recycling device to the bottom of the equipment, ground gaps or gaps between equipment parts, making it difficult to recycle the residual powder, reducing the recycling rate and causing resource waste. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage of preventing residual powder after metal 3D printing from falling from the main body of the recycling device to the bottom of the equipment, ground gaps or gaps between equipment parts, which makes it difficult to recycle the residual powder and reduces the recycling rate. To this end, we propose a recycling device for improving the utilization rate of metal 3D printing powder.

[0005] To achieve the above objectives, this application adopts the following technical solution: a recycling device for improving the utilization rate of metal 3D printing powder, comprising a recycling device body, a collection device provided on the lower surface of the recycling device body, the collection device including a fixing frame, the fixing frame being fixedly connected to the lower surface of the recycling device body, a circular hole being opened on the surface of the recycling device body, a collection chamber being slidably connected to the inner surface of the fixing frame, a fixing rod being fixedly connected to the surface of the collection chamber, a single-hole plate being rotatably connected to the arc surface of the fixing rod, and two L-shaped plates being fixedly connected to the surface of the fixing frame, with bolts inserted into the internal threads of the L-shaped plates.

[0006] Preferably, a movable frame is slidably connected inside the fixed frame, the movable frame has a square hole on its surface, a filter plate is slidably connected to the surface of the square hole of the movable frame, and a threaded rod is threadedly inserted into one side of the fixed frame.

[0007] Preferably, a torsion spring is fitted onto the arc surface of the fixing rod, and the two ends of the torsion spring are fixedly connected to the fixing rod and the single-hole plate, respectively.

[0008] Preferably, a blocking plate is fixedly connected to the arc surface of the bolt, and the surface of the blocking plate is in contact with the L-shaped plate.

[0009] Preferably, the surface of the movable frame is provided with a disassembly device, which includes four U-shaped frames. All four U-shaped frames are fixedly connected to the surface of the movable frame. A round rod is fixedly connected to the inner surface of the U-shaped frame. An inclined block is slidably connected to the arc surface of the round rod. A round plate is fixedly connected to one end of the round rod. The surface of the inclined block is slidably connected to the filter plate.

[0010] Preferably, a spring is fitted onto the arc surface of the round rod, and the two ends of the spring are fixedly connected to the U-shaped frame and the inclined block, respectively.

[0011] Preferably, a buffer pad is fixedly connected to the surface of the inclined block, and the surface of the buffer pad is in contact with the circular plate.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, by setting up a collection device, the effect of collecting powder waste is achieved, avoiding the residual powder after metal 3D printing from falling from the main body of the recycling device to the bottom of the equipment, ground gaps or gaps between equipment parts, which would make it difficult to recycle the residual powder, reduce the recycling rate, and cause resource waste, thus improving the practicality of the device.

[0014] In this utility model, by setting up a disassembly device, the effect of disassembling and replacing filter plates with different pore sizes is achieved. This avoids the situation where, when the staff uses the main body of the recycling device for collection and filtration, if the size of the filter plate of the recycling device is difficult to meet, the staff will need to prepare multiple devices, which would increase the investment cost. This improves the convenience of the device. Attached Figure Description

[0023] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods without changing the essential spirit of this utility model. Therefore, the following specific embodiments and accompanying drawings are merely exemplary descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction on the technical solution of this utility model.

[0024] Reference Figure 1 As shown, this utility model provides a technical solution: a recycling device for improving the utilization rate of metal 3D printing powder, including a recycling device body 1. A collection device 2 is provided on the lower surface of the recycling device body 1. By setting the collection device 2, the powder waste is collected, preventing residual powder after metal 3D printing from scattering from the recycling device body 1 to the bottom of the equipment, ground gaps, or gaps between equipment parts, which would make it difficult to recycle the residual powder, reduce the recycling rate, and cause resource waste. This improves the practicality of the device. A disassembly device 3 is provided on the surface of the movable frame 208. By setting the disassembly device 3, the filter plates 209 with different pore sizes can be disassembled and replaced. This avoids the situation where the size of the filter plates 209 of the recycling device body 1 is insufficient when the staff uses the recycling device body 1 for collection and filtration, which would require the staff to prepare multiple devices, increasing investment costs. This improves the convenience of the device.

[0025] The following section will describe the specific setup and function of the collection device 2 and the dismantling device 3.

[0026] Reference Figure 2 , Figure 3 and Figure 4As shown in this embodiment: the collection device 2 includes a fixed frame 201, which is fixedly connected to the lower surface of the recycling device body 1. A circular hole is provided on the surface of the recycling device body 1. A collection chamber 202 is slidably connected to the inner surface of the fixed frame 201. A fixed rod 203 is fixedly connected to the surface of the collection chamber 202. A single-hole plate 204 is rotatably connected to the arc surface of the fixed rod 203. Two L-shaped plates 205 are fixedly connected to the surface of the fixed frame 201. Bolts 206 are threaded into the L-shaped plates 205. A movable frame 208 is slidably connected inside the fixed frame 201. A square hole is provided on the surface of the movable frame 208. A filter plate 209 is slidably connected to the surface of the square hole of the movable frame 208. A threaded rod 210 is threaded into one side of the fixed frame 201, achieving the effect of filtering powder waste of different sizes. The filter plate 209 can be adjusted according to the printing process requirements. It supports multiple aperture specifications to meet the powder recycling standards of different materials and equipment. The arc surface of the fixing rod 203 is fitted with a torsion spring 211. The two ends of the torsion spring 211 are fixedly connected to the fixing rod 203 and the single-hole plate 204 respectively, which achieves the effect of automatically opening the single-hole plate 204 and keeping the single-hole plate 204 in the open state. This reduces the number of work steps for the workers and improves their work efficiency. The arc surface of the bolt 206 is fixedly connected with a blocking plate 207. The surface of the blocking plate 207 is in contact with the L-shaped plate 205, which achieves the effect of preventing the bolt 206 from falling off. This avoids the situation where the bolt 206 is rotated too many times when the workers rotate it, so that the arc surface of the bolt 206 separates from the L-shaped plate 205, which would require the workers to reinstall it during use and increase their workload.

[0027] Reference Figure 5 and Figure 6 As shown, specifically, the disassembly device 3 includes four U-shaped frames 31, all of which are fixedly connected to the surface of the movable frame 208. A round rod 32 is fixedly connected to the inner surface of each U-shaped frame 31. An inclined block 33 is slidably connected to the arc surface of the round rod 32. A round plate 34 is fixedly connected to one end of the round rod 32. The surface of the inclined block 33 is slidably connected to the filter plate 209. A spring 36 is fitted onto the arc surface of the round rod 32. Both ends of the spring 36 are fixedly connected to the U-shaped frame 31 and the inclined block 33 respectively, thus stabilizing the inclined block 33. As a result, the filter plate 209 always maintains the correct position and will not be displaced due to vibration, ensuring stable screening accuracy. The surface of the inclined block 33 is fixedly connected to the buffer pad 35, and the surface of the buffer pad 35 is in contact with the circular plate 34. At this time, the effect of absorbing the collision force between the circular plate 34 and the inclined block 33 is achieved. The buffer pad 35 can absorb the collision force between the inclined block 33 and the circular plate 34, reduce the wear and fatigue damage caused by direct contact between metals, improve the durability of components such as the inclined block 33 and the circular rod 32, and reduce maintenance costs.

[0028] Working principle: When waste material flows through the circular hole of the recycling device body 1 and passes through the filter plate 209, it falls into the collection bin 202. When the operator needs to pull out the collection bin 202, the operator first rotates the bolt 206. At this time, the bolt 206 drives the baffle plate 207 to move until the surface of the baffle plate 207 is in contact with the L-shaped plate 205. At this time, the arc surface of the bolt 206 is completely separated from the single-hole plate 204. At this time, the torque of the torsion spring 211 drives the single-hole plate 204 to rotate on the arc surface of the fixed rod 203 until the position of the single-hole plate 204 does not affect the movement of the collection bin 202. At this time, the operator can pull the collection bin 202 to slide in the fixed frame 201 until the collection bin 202 is completely pulled out. At this time, the operator can reuse it. This achieves the effect of collecting powder waste, avoiding the residual powder after metal 3D printing from the recycling device body 1 to the bottom of the equipment, ground gaps or equipment parts gaps, which would make the residual powder difficult to recycle, reduce the recycling rate, and cause resource waste. This improves the practicality of the device.

[0029] When the operator needs to replace the filter plate 209 with a different pore size, the operator first pushes the inclined block 33 to slide on the arc surface of the round rod 32. At this time, the spring 36 is compressed until the surface of the inclined block 33 separates from the filter plate 209. Then the operator can pull the filter plate 209 until the surface of the filter plate 209 separates from the moving frame 208. Then the operator can replace the filter plate 209 with a different pore size. After the replacement is completed, the operator can release the inclined block 33. At this time, the rebound force of the spring 36 drives the inclined block 33 to move, and the inclined block 33 drives the buffer pad 35 to move until the surface of the buffer pad 35 is in contact with the round plate 34. At this time, the effect of disassembling and replacing the filter plate 209 with a different pore size is achieved. This avoids the situation where the operator needs to prepare multiple devices when using the main body of the recycling device 1 for collection and filtration, if the size of the filter plate 209 of the main body of the recycling device 1 is not sufficient, which would increase the investment cost. This improves the convenience of the device.

[0030] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
