[0002] Packaging refers to the general name of containers, materials and auxiliary materials used according to certain technical methods to protect products during circulation, facilitate storage and transportation, and promote sales. During the production process of paper packaging boxes, due to the need to cut fixed shapes and holes, etc., small pieces of waste will be left on the entire cardboard. Factories usually collect this part of the waste, and after crushing and pulping, they are re-manufactured to achieve the reuse of waste.

[0003] In the patent document with publication number CN111282677A, a packaging carton shredder is disclosed, which utilizes the active roller and the driven roller of the shredding mechanism to cooperate with each other to achieve shredding of the carton. However, the relative movement of the active roller and the driven roller makes it easy for the carton to be bent and deflected during the shredding process, thereby failing to achieve the shredding effect. After shredding, the carton still has a large block structure and needs to be shredded again, and its shredding efficiency is poor. Therefore, in order to solve the above problems, the present application provides a packaging waste shredding device.
