Abstract
Description
Technical Field
[0001] This utility model relates to the field of particle mixing technology, specifically to a plastic particle mixing device equipped with a threaded lifting mechanism. Background Technology
[0002] Plastics have a wide range of uses in daily life and production. In the production of plastic products, sometimes in order to give plastic products specific performance characteristics, different types of plastic granules are mixed in different proportions during the processing of plastic products. After mixing, they are processed to obtain the desired plastic products. At present, the common method for processing different types of plastic granules is to pour different types of plastic granules together and then stir them. This mixing method sometimes results in the plastic granules not being mixed evenly. Utility Model Content

[0010] The above technical solution involves placing different plastic granules into separate material bins, using a threaded lifting mechanism to guide the material into the mixing bin, where it falls into the mixing tank. The stirring motor and rotary motor are then activated. The rotary motor drives the mixing tank to rotate via gears. During rotation, the granules are mixed and pass through the sieve holes in the bottom wall of the mixing tank into the lower part of the mixing bin. Simultaneously, the stirring motor drives the stirring rod to rotate, which in turn drives the stirring blades to rotate, further mixing the granules.
