Technical field

The invention relates to the field of plastic molding devices, and in particular to a plastic particle stirring device.

Background technique

Plastic products are products produced with plastic as the basic raw material. In the process of producing plastic products, plastic raw materials and auxiliary materials need to be mixed, and then the plastic products are produced through injection molding machines and other equipment, so a mixing device is required. . For example, patent application number: CN201810861736.6 discloses a raw material stirring device for plastic product processing. When the user uses the device, the servo motor is started to drive the threaded rod to rotate, and the limit block is used under the action of the limit groove, thereby The threaded sleeve moves upward, causing the filter screen to move upward, filtering out the lumps in the raw materials. When the threaded sleeve moves upward, under the action of the slider and the chute, the moving sleeve follows the threaded rod. It can also move upward when rotating to increase the mixing effect.
