The support fan blade 303 is fixedly provided on the output shaft of a driving motor.

[0027] As Figures 1 to 7As shown, the voltage stabilizing unit 1 includes a voltage stabilizing adjustment knob 101, a voltage stabilizing slide rod 102, a voltage stabilizing spring 103, a voltage stabilizing outer shell 104, and a voltage stabilizing connecting pipe 105. The voltage stabilizing outer shell 104 is detachably arranged on the support outer shell 302, and the support outer shell 302 is connected to the voltage stabilizing outer shell 104 through a flange. A voltage stabilizing slide rod 102 is slidably arranged in the voltage stabilizing outer shell 104, and a voltage stabilizing spring 103 is arranged between the voltage stabilizing slide rod 102 and the voltage stabilizing outer shell 104. When the voltage stabilizing slide rod 102 slides, it controls the gas flow rate of the bottom channel of the voltage stabilizing outer shell 104; a voltage stabilizing connecting pipe 105 is arranged on one side of the voltage stabilizing outer shell 104 close to the support outer shell 302, and the other end of the voltage stabilizing connecting pipe 105 is connected to the top of the voltage stabilizing outer shell 104; a voltage stabilizing adjustment knob 101 is arranged on the top of the voltage stabilizing outer shell 104, and the voltage stabilizing adjustment knob 101 is threadedly connected to the voltage stabilizing outer shell 104.

[0028] As Figures 1 to 10 As shown, a plurality of connecting parts 2 are arranged on the support vacuum buffer tank 301. The connecting part 2 includes a connecting fixed joint 201, a connecting sleeve 202, a first connecting return spring 203, a first connecting closing ball 204, a connecting ejector rod 205, a second connecting closing ball 206, a second connecting return spring 207, and a connecting rotating joint 208. The connecting fixed joint 201 is fixedly arranged on the support vacuum buffer tank 301. A first connecting closing ball 204 is slidably arranged in the connecting fixed joint 201. The first connecting closing ball 204 is connected to the connecting fixed joint 201 through the first connecting return spring 203. A connecting ejector rod 205 is fixedly arranged on the first connecting closing ball 204. A connecting sleeve 202 is rotatably sleeved outside the connecting fixed joint 201. The connecting sleeve 202 is threadedly engaged with the connecting rotating joint 208. A second connecting closing ball 206 is slidably arranged in the connecting rotating joint 208. The second connecting closing ball 206 is connected to the connecting rotating joint 208 through the second connecting return spring 207.

[0029] As Figures 1 to 10As shown in the figure, the working principle of a centralized vacuum pumping device disclosed by the present utility model is as follows: Place the device at an appropriate position, connect the ventilation pipe connected to the rotating joint 208 to the vacuum pumping port of the inner packaging machine, and then install the rotating joint 208 on the connecting sleeve 202. At this time, the connecting push rod 205 pushes the connecting closing ball one 204 and the connecting closing ball two 206, causing the connecting closing ball one 204 and the connecting closing ball two 206 to slide and compress the connecting return spring one 203 and the connecting return spring two 207, opening the channel formed by the connecting closing ball one 204 and the connecting fixed joint 201, and at the same time opening the channel formed by the connecting closing ball two 206 and the rotating joint 208; At this time, the ventilation pipe on the rotating joint 208 connects the vacuum pumping port of the inner packaging machine to the chamber in the support vacuum buffer tank 301; Start the drive motor, and the drive motor drives the support fan blade 303 to rotate. The rotation of the support fan blade 303 pumps the air in the vacuum pumping port of the inner packaging machine from the ventilation pipe on the rotating joint 208 into the support vacuum buffer tank 301, and then into the support housing 302 through the support vacuum buffer tank 301, and finally discharges from the channel at the bottom of the voltage stabilizing housing 104, completing the work of vacuum pumping for the inner packaging machine.

[0030] During the exhaust process, when the exhaust pressure at the bottom channel of the voltage stabilizing housing 104 exceeds the predetermined pressure value, the excess gas enters the cavity at the top of the voltage stabilizing housing 104 through the voltage stabilizing connecting pipe 105, pushing the voltage stabilizing slide rod 102 to move downward, reducing the channel formed by the voltage stabilizing slide rod 102 and the bottom of the voltage stabilizing housing 104, achieving the balanced discharge of gas pressure. Furthermore, the vacuum system can adapt to changes in internal and external conditions in real time, ensuring stable vacuum degree, effectively reducing the instability of the vacuum degree caused by exhaust pressure fluctuations, and improving the system stability.

[0031] The operator can also manually turn the voltage stabilizing adjustment knob 101 according to the actual usage requirements, so that the voltage stabilizing adjustment knob 101 pushes the voltage stabilizing slide rod 102, changing the size of the channel formed by the voltage stabilizing slide rod 102 and the bottom of the voltage stabilizing housing 104, and then adjusting the corresponding pressure value.

[0032] After the vacuum extraction is completed, the operator can rotate the rotating joint 208 to quickly remove the rotating joint 208, the connecting closing ball two 206, and the connecting return spring two 207. At this time, since the connecting closing ball two 206 is separated from the connecting closing ball one 204, under the action of the connecting return spring one 203, the connecting closing ball one 204 closes the channel formed by the connecting fixed joint 201 and the connecting closing ball one 204, creating an open circuit here, and air cannot enter the device; It does not affect the vacuum extraction work of the remaining devices connected to the connecting part 2, facilitating the installation and disassembly of the vacuum pumping device and the device to be vacuum pumped.
