[0040] In order to ensure that the topmost paperboard can be smoothly moved to the right by the suction head 21, and the second topmost paperboard is blocked and cannot be moved synchronously, the height of the baffle 42 is adjustable, so that the upper edge of the baffle 42 is located between the topmost paperboard and the second topmost paperboard, and the baffle 42 can adapt to corrugated paperboards or solid paperboards of different thicknesses, and single-layer conveying is more flexible.

[0041] In further embodiments, the pressing plate 4 is laterally installed in a square frame, and the slide frame 41 is inserted and installed in the square frame, and the spacing between the front and rear slide frames 41 is installed;

[0042] In order to adapt to paperboards of different widths, the baffle 5 can be lifted to disengage, and the position is adjusted front and back, at this time, the slide frame 41 can also slide in the square frame, and the position of the two baffles 42 is adjusted, and the adaptability is strong.

When the roughness level of the surface of the paperboard is high, the negative pressure adsorption force is insufficient, so the lifting height is reduced to ensure that the paperboard can be smoothly lifted. When the roughness level of the surface of the paperboard is low, the negative pressure adsorption force is large, and the lifting height is increased to offset the mutual attraction between the surfaces of adjacent paperboards (based on the existing physical principle that the smoother the surface, the greater the mutual attraction when the surfaces are in contact).

[0053] In a further embodiment, the exhaust pipe 6 is provided with a goose neck pipe 61 at the gas outlet end, the goose neck pipe 61 is provided with a spray pipe 62 at the gas outlet end, and the spray pipe 62 is provided with a spray hole close to the baffle 5.

[0054] In order to further improve the separation effect of the top layer paperboard and the second layer paperboard, the tail flow of the vacuumization is sprayed from the position of the spray pipe 62 to the paperboard. When the right side of the top layer paperboard is lifted, the gas can enter the space between the top layer paperboard and the second layer paperboard more quickly, and the gas is blown on the top of the top layer paperboard and the top of the second layer paperboard, so that the force can further separate the top layer paperboard and the second layer paperboard.

[0055] In a further embodiment, the goose neck pipe 61 and the spray pipe 62 are rotationally connected, a motor for driving the rotation of the spray pipe 62 is arranged at the rotation position, and a height sensor facing the paperboard is arranged below the spray pipe 62.

[0056] In order to adapt to the height change of the paperboard stack, the height sensor adopts a laser sensor, the height change of the paperboard stack can be detected, and the motor can drive the nozzle 62 to rotate according to the height signal, so that the airflow can be stably blown between the top layer of paperboard and the second top layer of paperboard, and the utilization stability of the wake flow is ensured. Of course, in actual use, if the paperboard thickness is large, the precision requirement of the jet direction is not high, then the function can be closed, and the energy consumption is reduced.

[0057] The power supply module, the control circuit, the processing and the electronic components and the control module involved in the application are all prior art, and the skilled person in the art can realize them without further description. The content protected by the application does not involve improvement of internal structure and method.

[0058] The above is only a preferred specific embodiment of the application, but the protection scope of the application is not limited to this. Any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the application within the technical range disclosed by the application, which should be covered by the protection scope of the application.
