9. An extrusion method of a twin-screw extruder for producing nylon plastic raw materials, characterized in that the twin-screw extruder for producing nylon plastic raw materials as claimed in claim 8 is used, comprising the steps of:
s1, when air bubbles in materials are required to be discharged, a second motor (13) arranged on a mounting plate drives a rotary stirring frame (14) to rotate, so that the materials in a feeding box (6) are stirred, when the materials are stirred, a third motor (16) arranged on the rotary stirring frame (14) drives a power rod (17) to rotate, when the power rod (17) rotates, a connecting rod (18) which is rotationally connected with the power rod (17) is driven to rotate, and then a driving rod (15) which is rotationally connected with the connecting rod (18) is driven to lift, so that a kneading plate (7) which is rotationally connected with the rotary stirring frame (14) is driven to swing, the materials are kneaded during stirring, and then air bubbles in the materials are kneaded, so that the air bubbles in the materials are effectively reduced;
the first electric cylinder (10) arranged on the fixing frame (9) drives the fixing plate (11) to stretch and retract, and the exhaust fork (12) fixedly connected with the fixing plate (11) is driven to penetrate in the extrusion box (4) through the stretch and retract of the fixing plate (11), so that air bubbles in materials to be extruded are punctured, and then air in the punctured air bubbles is discharged through the force of extruding the materials, so that the materials are extruded into a material strip through a discharge hole formed in the extrusion plate (5);
s2, when the materials remained in the extrusion sleeves (1) need to be cleaned, a fourth motor (22) arranged on the underframe (21) drives a bidirectional screw rod (23) to rotate, so that driving blocks (8) fixedly connected with the two extrusion sleeves (1) are driven to move, the two extrusion sleeves (1) are driven to open and close, and therefore operators can conveniently clean the materials remained in the extrusion sleeves (1);
after cleaning, a third electric cylinder (27) arranged on the electric cylinder frame drives the locking frame (28) to stretch out and draw back, so that two adjacent locking plates (26) are inserted into the locking frame (28), and the two extrusion sleeves (1) are locked when closed.
