Description

Plastic particle grinding machine Technical Field The utility model belongs to the technical field of abrasive machines, and particularly relates to a plastic particle abrasive machine. Background The plastic particle grinding machine is a special device for plastic particle refinement treatment, and is mainly used for processing plastic raw materials through grinding or polishing processes so as to realize precise control of particle size or surface modification. After finishing plastics crocus, current plastic particle abrasive material machine, plastics powder stop and pile up at the discharge gate, and bridging phenomenon appears in plastics powder easily, and then causes the phenomenon of feed opening jam, and plastics powder is difficult to high-efficient abundant discharge. Therefore, a plastic particle grinding machine is proposed. Disclosure of Invention The utility model provides a plastic particle grinding machine, which aims to solve the problems. The embodiment of the utility model provides a plastic particle grinding machine, which comprises a grinding machine body, a discharging hopper arranged at the bottom of the grinding machine body, a plastic particle arch breaking assembly and a driving assembly which are arranged on the discharging hopper, wherein the plastic particle arch breaking assembly comprises an inner sliding ring which slides on the inner side wall of the discharging hopper, a supporting frame arranged at the top of the inner sliding ring, an arch breaking rod which rotates on the inner side wall of the supporting frame, a torsion spring arranged between the outer side wall of the arch breaking rod and the inner side wall of the supporting frame, a limiting block arranged at the position of the inner side wall of the supporting frame close to the lower side of the arch breaking rod, a movable guide table arranged at the position of the top of the arch breaking rod close to one end, and a fixed guide table axially and equidistantly arranged on the inner side wall of the discharging hopper. The driving assembly comprises an outer rotating ring sliding on the outer side wall of the discharging hopper, a strong magnetic block embedded in the inner side wall of the outer rotating ring, an iron block arranged on the outer side wall of the inner rotating ring, a plurality of gear teeth axially and equidistantly arranged on the outer side wall of the outer rotating ring, a motor arranged on the outer side wall of the discharging hopper, and a gear arranged at the output end of the motor. Further, the cross section of the movable guide table is right trapezoid, and the top of the movable guide table is an inclined plane; By adopting the technical scheme, the follow-up guiding force can be utilized to push the movable guide table to move by utilizing the guiding capability formed by the inclined surface on the movable guide table, so that the arch breaking rod can move.
