The air guide pipe 11 and the valve 13 are connected to each other. The air suction pump used at door 13 is connected to the frequency converter, and the power of the air suction pump is controlled by the frequency converter. The power of the air suction pump is adjusted according to the indication displayed on the flow meter 12, so that the air suction pump generates different air pressures at the manifold 10, and the gas flow transmitted to the inside of the manifold 10 through the air duct 11 is detected by the flow meter 12, which is beneficial to control the air pressure inside the manifold 10, and by opening and closing different valves 29 and valves 13, different air ducts 28 and air ducts 11 are used to transmit gas, so that the inside of the manifold 10 is adapted to generate different negative pressures, which is beneficial to use air pressures of different powers to adsorb the transmitted cartons, improve the adsorption effect, and facilitate the adjustment of the adsorption pressure suitable for a larger range, thereby improving the transmission efficiency.

[0029] Reference Figure 1 and 4 The bellows also includes a filter assembly for filtering the gas inside the air duct 11.

[0031] Reference Figure 1 There are multiple air ducts 8, and the inner wall of the confluence pipe 10 is contracted from top to bottom. The air duct 8 is connected to the contraction of the side wall of the confluence pipe 10. The contraction of the inner wall of the confluence pipe 10 facilitates the transmission of the transmitted gas to a smaller space, which is beneficial to connecting multiple air ducts 8, so that the transmission hole of the air duct 8 can face the end of the confluence pipe 10 toward the transported carton, which is beneficial to the transmission of gas inside the confluence pipe 10.
