[0027] 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.

[0028] like Figure 1-11 As shown, a main unit area feeding and discharging system is characterized in that it includes several overflow powder tanks 8 and powder suction modules 9, several printers 4, powder feeding modules, and powder discharge tanks 51. The overflow powder tanks 8 are connected in series with powder discharge pipes 6 via air supply pipes 7. The printers 4 are connected in series and are respectively connected to the overflow powder tanks 8. The air supply pipes 7 are connected to the powder suction modules 9, and the powder discharge pipes 6 are connected to the powder suction modules 9. The powder discharge tanks 51 are installed on each printer 4. A powder feeding pipe 3 and an air supply pipe 2 are provided between the powder feeding module and the powder discharge tanks 51 of the printers 4. The powder feeding module includes a chassis 1 and a powder feeding bin 12. The powder feeding pipe 3 is connected to the powder feeding bin 12, and the air supply pipe 2 is connected to the powder feeding bin 12.

[0029] Furthermore, the casing 1 is equipped with an exhaust filter element 11, and a sealing pump 13 is installed inside the casing 1. The exhaust pipe 2 passes through the casing 1 and is connected to the sealing pump 13 inside. The exhaust pipe 2 is a vacuum pumping line.

[0030] Furthermore, the powder suction module 9 includes a frame 93, a filter element 92, a powder discharge bin 94, and a powder hopper assembly 91. The filter element 92 is disposed within the powder hopper assembly 91. A connecting pipe is provided between the powder hopper assembly 91 and the powder discharge bin 94 and is fixed to the frame 93. The frame 93, the housing 1, and the upper part are all equipped with cooling fans 95. The cooling fans 95 are used for heat dissipation.

[0031] Furthermore, the overflow tank 8 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 outlet pipe 6.

[0032] Furthermore, a high level sensor 53 and a bottom level sensor 52 are installed on the powder discharge tank 51 and the powder overflow tank 8.

[0033] Furthermore, the powder discharge tank 51 is also provided with an air outlet 56 and a first powder inlet 55. The air outlet 56 is connected to the air outlet pipe 2, and the first powder inlet 55 is connected to the powder delivery pipe 3.

[0034] Furthermore, the powder discharge tank 51 is equipped with an oxygen sensor 54 and a pressure sensor 57 to continuously monitor pressure and oxygen content.

[0035] Furthermore, the powder discharge tank 51 and the overflow tank 8 are also equipped with an exhaust solenoid valve 58, and the powder discharge tank 51 is also equipped with an air inlet 59. The exhaust solenoid valve 58 of the powder discharge tank 51 has two air pipe interfaces 581, and each air pipe interface 581 is connected to a rubber tube 591 that is connected to the exhaust filter element 11 at both ends. Inert gas is injected into the interior through the air inlet 59, and the exhaust solenoid valve 58 and the exhaust filter element 11 are cleaned by air.

[0036] Furthermore, the powder hopper assembly 91 is provided with a second powder inlet 911 that is connected to the powder outlet pipe 6.

[0037] This application involves separate air circulation and washing between the printer 4, the toner delivery module, and the overflow toner tank 8, with real-time monitoring of pressure and oxygen content. The air washing process ends once the target is met.

[0038] Based on the number of alarms from the high-level sensor 53 in the powder discharge hopper, the equipment is in standby mode when there are no alarms; a single alarm triggers the powder discharge hopper to begin sucking powder from the powder delivery hopper 12, controlling powder suction and discharge in conjunction with the powder discharge hopper's level control; multiple alarms trigger a priority-based powder suction mechanism. During powder suction, the levels in the powder discharge hopper and the powder delivery hopper 12 are continuously monitored to control powder suction, discharge, and program shutdown.

[0039] After the printer 4 finishes its work, a small amount of waste material remains and is sucked into each overflow toner can 8. When the high level sensor 53 of the overflow toner can 8 alarms, the toner suction module 9 sucks in the waste powder from the overflow toner can 8, filters and collects it, and then sends it to an external screening device for screening so that it can be used by the powder feeding device.

[0040] Meanwhile, after the equipment is powered on, it monitors the pressure and oxygen content globally and controls the opening and closing of the solenoid valve based on the data to ensure the safety of powder suction. It achieves orderly, safe and efficient control of powder suction operation, and realizes the technical effects of rationally planning the powder suction sequence, accurately controlling the 12 material levels of the powder dropping bucket and the powder feeding bucket, and real-time adjustment of pressure and oxygen content. This effectively improves the powder suction efficiency, avoids powder overflow and ensures the safety and stability of the powder suction process.

[0041] 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.
