The conveying mechanism is provided with a lifting mechanism and a moving mechanism. The lifting mechanism drives the gripper mechanism to lift and lower, and the moving mechanism drives the gripper mechanism to deliver the bag to the bag cutting mechanism for cutting and then to the bag shaking mechanism. The bag cutting mechanism is provided with multiple spaced cutters to cut the bag. The bag shaking mechanism is provided with a fixed frame and a moving frame. The moving frame moves relative to the fixed frame to open the cut of the bag multiple times to achieve bag shaking. A discharge hopper is provided below the bag shaking mechanism.

[0013] The beneficial effects of this utility model are as follows: multiple bags are picked up by the gripper mechanism and cut while being conveyed. After the bags are cut, they are sent to the bag shaking mechanism for shaking. The bag shaking mechanism achieves multiple opening and closing of the cut through the cooperation of the moving frame and the fixed frame, quickly completing the bag shaking and shaking out the plastic particles inside the bag. This realizes automatic feeding, bag cutting and plastic particle shaking, realizing the transformation from manual to automated production and improving production efficiency.
