In the production process of plastic particles, a screening machine is needed to screen plastic particles of different sizes. China's authorized utility model patent (Announcement No.: CN219883011U) discloses a vibrating screening machine for the production of modified PC plastic particles. By setting a pulley in the device, the device can be portable and movable.

[0003] However, the above device still has some shortcomings during use: the plastic particles after screening in the above device fall into the storage box. As the plastic particles stored in the storage box increase, workers are required to take them out from the content bin. Since the storage box filled with plastic particles is heavy, when the workers pull out the storage box, the sliding friction between the storage box and the bottom of the content bin is large, which makes it more laborious for the workers to take out the storage box. Therefore, a plastic particle screening machine for plastic production is proposed to address the above situation. Utility Model Content
