A stirring method, based on a polyester resin that is easy to clean up according to claim 8, is realized by a stirring device, characterized in that, comprising the steps: Step 1, adding the polyester resin raw material to the interior of the mixing drum (2) according to the proportioning; Step 2: Turn on the first motor (13), so that the rotating shaft (8) equipped with the helical lifting blade (9) inside the lifting cylinder (7) rotates, and the raw material of the polyester resin enters through the first port (23), Under the rotation of the helical lifting blade (9), it is lifted upwards, thereby forming a vertical circulation of the polyester resin raw material inside the mixing drum (2). the top end of ; Step 3: Drive the first rotary table (11) equipped with the driven gear (25) to rotate under the transmission of the first transmission gear (27) and the second transmission gear (28), thereby realizing the rotation of the mesh cylinder (5). At this time, the mesh cylinder (5) moves in the opposite direction to the lifting cylinder (7) equipped with the spiral downward pressing blade (10), and continuously squeezes and descends the upper raw material. Under the action of the filter screen, the granular raw material is blocked on the inside. , and gradually move to between the edge of the spiral downward pressing blade (10) and the mesh cylinder (5), and the grinding grain structure on the edge of the spiral downward pressing blade (10) can quickly pulverize the granular raw materials; Step 4: Reciprocating in turn, the polyester resin raw material participates in stirring and friction in the continuous vertical circulation.
