Description

Technical Field

[0001] This utility model relates to a powder suction system. Background Technology

[0002] 3D printing metal powder materials typically involve a single sieving and mixing process. This involves coarsely sieving the metal powder using a powder sieve before filling it into a powder mixer for further mixing. This ensures that the metal powder materials from the same batch are thoroughly and uniformly mixed, guaranteeing the stability of the performance of 3D printed products from that batch.

[0003] Metal powder that is not used after printing needs to be collected for reuse. This collection requires a centralized powder suction device. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a toner suction system. The toner overflow device collects waste toner from the printer, which is then collected by the toner suction module, making it highly practical.

[0006] Furthermore, the powder overflow device has 6 units.

[0007] Furthermore, the powder overflow device includes a powder overflow tank, which has a return air port and a powder outlet. The return air port is connected to an air supply pipe, and the powder outlet is connected to a powder supply pipe.

[0008] Furthermore, the overflow tank is equipped with a high level sensor and a low level sensor.

[0009] Furthermore, the overflow tank is also equipped with an exhaust solenoid valve, which is connected to the filter above the powder suction module using a rubber tube with an inner diameter of 19mm and an outer diameter of 26mm.

[0010] Furthermore, the exhaust solenoid valve is equipped with an oxygen sensor.

[0011] Furthermore, the powder suction module includes a frame, a filter element, a powder discharge bin, and a powder hopper assembly. The filter element is disposed inside the powder hopper assembly, and a connecting pipe is provided between the powder hopper assembly and the powder discharge bin and fixed on the frame.

[0012] Furthermore, the powder hopper assembly is provided with a powder inlet connected to the powder feeding pipe, and the frame is also provided with a cooling fan.

[0013] Compared with the prior art, the advantages of this application are: the overflow device collects the waste toner from the printer and then collects it through the toner suction module, which is practical. Attached Figure Description

Detailed Implementation

[0021] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0022] like Figure 1-6 As shown, a powder suction system is characterized in that it includes a plurality of powder overflow devices 8 and a powder suction module 5. The powder overflow devices 8 are connected in series with a powder delivery pipe 6 via an air delivery pipe 7. The air delivery pipe 7 is connected to the powder suction module 5, and the powder delivery pipe 6 is connected to the powder suction module 5.

[0023] Furthermore, the powder overflow device 8 has 6 units.

[0024] Furthermore, the powder overflow device 8 includes a powder overflow tank, which has a return air port 81 and a powder outlet 82. The return air port 81 is connected to the air supply pipe 7, and the powder outlet 82 is connected to the powder supply pipe 6.

[0025] Furthermore, a high-level sensor 83 and a low-level sensor 86 are installed on the overflow tank. The high-level sensor 83 and the low-level sensor 86 are used to detect the material level inside the overflow tank.

[0026] Furthermore, the overflow tank is also equipped with an exhaust solenoid valve 84, which is connected to the filter 501 above the powder suction module 5 using a rubber tube with an inner diameter of 19mm and an outer diameter of 26mm.

[0027] Furthermore, the exhaust solenoid valve 84 is equipped with an oxygen sensor 85. The oxygen sensor 85 detects the oxygen content.

[0028] Furthermore, the powder suction module 5 includes a frame 53, a filter element 52, a powder discharge bin 54, and a powder hopper assembly 51. The filter element 52 is disposed inside the powder hopper assembly 51, and a connecting pipe is provided between the powder hopper assembly 51 and the powder discharge bin 54 and fixed on the frame 53.

[0029] Furthermore, the powder hopper assembly 51 is provided with a powder inlet 511 connected to the powder feeding pipe 6, and the frame 53 is also provided with a cooling fan 55. The cooling fan 55 serves to dissipate heat.

[0030] First, this application connects to each printer and performs individual air washing. After the air washing is completed, the oxygen content drops to 2%, and the waste toner in the printer is sucked into the overflow toner tank. After the high level sensor 83 of each overflow toner tank alarms, the toner suction module 5 sucks in the waste toner from the overflow toner tank, filters and collects it, and monitors the oxygen content in real time, which effectively improves the toner suction efficiency.

[0031] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application's technical solution are the same as or can be implemented using existing technologies, and will not be described in detail here.
