[0017] The core number detection subsystem 2 includes a detection switch 28, which is installed at the output end of the transmission differential subsystem 1. The detection switches 28 are set to 3 groups, and each group of detection switches 28 is installed symmetrically up and down to form a facing relationship. The support frame 4 can be installed with a switch bracket 1 25, a switch bracket 26 and a switch bracket 3 27 for installing the detection switch 28.

[0018] The air circuit frequency conversion subsystem 3 includes an air suction cavity 29, an air pipe joint 30, an air pipe 31, a filter valve 34, a switch valve 35 and an air pump 36. The air suction cavity 29 is respectively placed inside the side plate 1 8, the side plate 2 9 and the conveyor belt 18 and connected to the side plate 1 8 and the side plate 2 9; the air suction cavity 29 is connected to the air pipe 31 through the air pipe joint 30, and the air pipe 31 is connected in series with the filter valve 34 and the switch valve 35 to the air pump 36. The air suction port of the air pipe 31 is installed in parallel, and the air pipe 31 can be connected with a hose or a hard pipe. The air pipes 31 of the two air suction cavities 29 are connected by a 90-degree elbow 32 and a three-way joint 33, and can adopt a "two-in-one" air suction method or an independently installed air suction method.

[0019] The upper surface of the suction cavity 29 is provided with suction holes and is closely attached to the bottom of the conveyor belt 18, and the interior of the suction cavity 29 is sealed. The conveyor belt 18 is also provided with through holes as adsorption holes for airflow to pass through.

[0020] The support frame 4 is provided with a safety cover plate 1 6 and a safety cover plate 2 11 on both sides.

[0021] The power transmission wheel of the driving shaft assembly 16 is larger than the power transmission wheel of the driven shaft assembly 13, so that the exit speed V1 and the entry speed V2 of the transmission belt 18 form a speed difference, V1>V2.

[0022] A cigarette sorting device 5 is provided in the middle of the outlet and inlet conveyor belts 18 , and the cigarette sorting device 5 is used to keep the cigarettes in a proper position when the cigarettes pass through the gap between the outlet and inlet conveyor belts 18 .

[0024] The centering device 7 is arranged on both sides of the conveyor belt 18 to ensure that the cigarette strips are in the middle.

[0025] Working principle of the present invention: First, the transmission surface of the present invention can be adjusted up and down to adapt to the access equipment at both ends. The length and width of the transmission differential subsystem 1 can be set according to the actual use situation, wherein the outlet length L1 can make the cigarettes reliably separated, and the inlet length L2 can make the subsequent cigarettes densely cached in the suction state. The width B1 of the left and right guide devices is adjustable to adapt to cigarettes of various lengths.

[0026] Secondly, the conveyor belt 18 has densely and evenly distributed adsorption holes, and the linear speed V1>V2 of the conveyor belts at the outlet and inlet forms a speed difference, ensuring that the cigarettes of each order are pulled apart for separation and counting. The linear speeds V1 and V2 can be adjusted by the frequency converter. When the cigarettes maintain normal operation to the length section L2 at the inlet of the transmission differential subsystem 1, the cigarettes are adsorbed on the conveyor belt 18 with holes at the inlet through the negative pressure state of the suction cavity 29 with adsorption holes on the surface. After the cigarettes pass through the transition wheel assembly 15 and the cigarette sorting device 5 in the middle of the transmission differential subsystem 1, they enter the conveyor belt 18 at the outlet. The outlet L1 pulls the cigarettes apart by a certain distance according to the speed difference for separation, and adsorbs the cigarettes on the conveyor belt with holes at the outlet through the negative pressure state of the suction cavity 29 with adsorption holes on the surface. At this time, the inlet cigarettes are reliably adsorbed on the inlet conveyor belt 18 to wait, realizing dense caching of subsequent cigarettes. After entering the transmission differential subsystem 1, the cigarettes are affected by their own gravity and the suction of the suction chamber 29. Even if the speed of the conveyor belt 18 is fast, the cigarettes can be stably on the conveyor belt 18 without deviation, which affects the cigarette posture and ensures the accuracy of the core count. The cigarettes of the order run to the detection switch at the outlet and are counted by the detection switch. After the core count of the cigarettes of the order is correct, the separation and core count of the cigarettes of the next order are carried out at the same time, and the same operation steps are performed. The front-end sorting equipment can perform normal sorting according to the information provided by the host computer and is not affected by this equipment. If there are multiple layers of sub-line sorting and confluence, the cigarettes at the outlet and inlet are adsorbed on the conveyor belt for parking and waiting. After the task of the previous order is completed, the separation and core count of the next order are continued by issuing instructions. Repeat the above operations by analogy, so that the separation and core count of the cigarettes of the order are realized, and the purpose of high-speed core count separation of the cigarettes of the order is achieved.
