[0003] A deburring device for plastic processing disclosed in the Chinese patent application publication specification CN217728206U makes the cylinder and the internal grinding balls shake synchronously to grind the burrs of the plastic parts. After the grinding is completed, the cover plate is removed, and the collection frame is lifted up and taken out by the cylinder. The plastic parts are quickly polished, the damage to the plastic parts is reduced, the integrity of the plastic parts is protected, time-saving and labor-saving grinding is more uniform, and the deburring effect is better.
