[0050] The paper is transmitted to the conveyor belt 52 through the front transmission rack 61. Due to the inertia of the conveyor belt 52 and the paper itself, the paper stops on the rack body 51. The controller drives the push rod assembly 21 to extend. The extended push rod assembly 21 pushes against the paper to reach the electronic weighing mechanism, and the weight is measured by the electronic weighing mechanism. The electronic weighing mechanism sends a signal to the controller. When the paper is qualified, the controller sends information to the push rod assembly 21. The push rod assembly 21 continues to extend forward to push the paper onto the conveyor belt 2 53. The paper is transmitted to the rear transmission rack 62 through the conveyor belt 2 53 and enters the next process. When the paper is unqualified, the controller sends information to the push rod assembly 22. The push rod assembly 22 pushes the paper out of the rack body 51 to eliminate unqualified products. The movements of the push rod assembly 1 21 and the push rod assembly 2 22 do not interfere with each other.
