the method comprises the following steps: two sealing covers at the top of a feeding box (12) are opened, raw materials are put in from two feeding ports at the top of the feeding box (12), the two sealing covers cover the two feeding ports, the raw materials fall into a conveying box (8) through four filter screens (17) on a rectangular frame (15) and enter an extrusion pipe (1) through a conveying port (9), a first motor (10) drives an extrusion screw rod (11), the extrusion screw rod (11) extrudes the raw materials from the extrusion pipe (1), a cast aluminum heater (18) heats the extrusion pipe (1) in a sectional mode in the extrusion process, waste heat generated by the cast aluminum heater (18) is discharged into the feeding box (12) through a heat exchange pipe (19), the raw materials which do not penetrate through the filter screens (17) in the feeding box (12) are heated and melted and fall into the extrusion pipe (1), meanwhile, a second motor (13) drives a screw rod to rotate forward and backward, the screw rod is matched with a connecting block to drive the rectangular frame (15) to lift through a connecting arm (14), scrapers (16) on the periphery of the rectangular frame (15) scrape the molten raw material retained on the inner wall of the feeding box (12) into the extrusion pipe (1);

step two: the third motor (21) drives the cutting knife (22) to rotate, the cutting knife (22) cuts an extruded material extruded from the extrusion pipe (1) to obtain plastic master batches, the circulating cooling water tank (28) is matched with the first connecting pipe (29) and the second connecting pipe (30) to circulate cooling water for the cooling water pipe (32), meanwhile, the fifth motor (31) is matched with two gears in meshed connection to drive the cooling water pipe (32) to rotate, and the cooling water pipe (32) is used for stirring and cooling the plastic master batches descending in the discharge box (20);

step three: fourth motor (26) drive gear rotates, the gear cooperatees with the rack, two translation board (24) reverse slip on bottom plate (25), and then drive transport case (8) and play workbin (20) reverse migration, the both ends of extrusion pipe (1) are exposed, pull down the bolt between location strip (6) and lower location strip (7), will go up box and lower box separation, extrusion pipe (1) exposes in the outside, and then pull down the bolt between snap ring (3) and lower snap ring (4), separate two arc pipe (2), can clear up arc pipe (2) inner wall.
