The method for using the sheath-core composite polyethylene fiber production device according to claim 1, characterized in that: The steps include: S1: preparing the prefabricated liquid raw materials for preparing the fiber core layer spinning solution, namely, preparing the ultra-high molecular weight polyethylene, additives and solution; S2: adding ultra-high molecular weight polyethylene and additives into the solvent, starting the second motor (1109) to drive the rotating shaft (1113) to rotate, the first motor (903) to drive the stirring shaft (902) to rotate, the spiral stirrer (904) cooperates with multiple groups of stirring rods to mix the raw materials, and the liquid breaking rack (907) reciprocates to break the mixed raw material liquid; S3: During the mixing process of the ultra-high molecular weight polyethylene, the additive and the solvent, the third motor (1110) is started to make the lifting rod (1103) perform reciprocating lifting motion during the rotation of the rotating column (1105), and the rotating shaft (1103) drives the top frame (1) to rotate, so that the stirring component continuously contacts the raw materials at different heights and positions, so as to achieve the purpose of sufficient mixing; S4: After the above raw materials are fully mixed, a prefabricated liquid for preparing the fiber core layer spinning liquid is obtained, which is discharged through the liquid outlet pipe at the bottom of the lower box (8) for subsequent processing.
