The check valve assembly comprises a first bracket connected with the conveying assembly, a mounting connected with the first bracket, a check valve plate rotationally connected with the mounting, and a reset connected with the first bracket and the check valve plate at both ends. The mounting is provided with a limiting part for limiting the rotation angle of the check valve plate. The check valve plate is inclined relative to the conveying direction of the conveying assembly and rotates to retract when subjected to external force, and rotates to extend under the action of the reset when not subjected to external force. The check valve plate extends to one-way block the articles conveyed by the conveying assembly. The pasting code machine is located behind the check valve plate.

[0005] The transportation assembly is used for conveying the packaged tobacco case, when conveying to the position of the code sticking machine, the code sticking machine sticks the code on the tobacco case, and then the transportation assembly sends away the tobacco case.
