The method for using the medium-to-large hot feed extruder rubber filter head according to claim 4, characterized in that: The following steps are involved: S1, the rotating cylinder (401) pushes the rotating shaft (402) to drive the rotating cylinder (406) to rotate, and the rotating cylinder (406) pushes the L-shaped connecting plate (407) to drive the machine head (301) to rotate, so that the end surface of the machine head (301) approaches the end surface of the machine head seat (2) until the end surface of the machine head (301) is parallel to the end surface of the machine head seat (2); S2, using the hydraulic cylinder (502) to push the hinge seat (503) to drive the locking ring (601) to rotate relative to the machine head seat (2), so that the locking teeth (602) of the locking ring are screwed into the inner side of the machine head locking teeth (304), and at the same time, the rotating cylinder (406) is pushed to drive the upper slider (403) and the lower slider (404) to contact the two butterfly springs (408) accordingly, so that the machine head (301) performs linear motion, so that the end face of the machine head (301) contacts the end face of the machine head seat (2); S3. During rubber filtering, the motor (307) drives the large ratchet rotating body (303) to rotate relative to the machine head (301) through the sprocket chain pair (308), and the large ratchet rotating body (303) drives the cutter (306) to rotate synchronously, so as to perform rotary cutting on the rubber material extruded from the rubber filtering plate (302). At the same time, the external temperature control device can control the temperature of the filling liquid in the cooling water channel (201), quickly dissipate heat and cool the filtered rubber material, and improve the quality of the rubber material after filtering; S4, obtaining oil pressure information of the hydraulic cylinder through a second pressure sensor installed in the hydraulic cylinder (502), obtaining temperature information of the filling liquid in the cooling water channel through a second temperature sensor, and comparing the temperature information and the oil pressure information with a preset temperature threshold and a preset pressure threshold. If the oil pressure information is not within the pressure threshold range, the hydraulic cylinder is adjusted until the oil pressure information is within the pressure threshold. If the temperature of the filling liquid is not within the temperature threshold, the external temperature control device is started to adjust the temperature of the filling liquid until the temperature of the filling liquid is within the temperature threshold. S5. Under the condition that the temperature information and the oil pressure information are within the corresponding temperature threshold and pressure threshold, the temperature information and the oil pressure information are dimensionlessly processed and then imported into the evaluation model to output the evaluation coefficient. The obtained evaluation coefficient is compared with the coefficient threshold. If the obtained evaluation coefficient is not within the coefficient threshold, it indicates that the working state of the hot feed extruder rubber filter head is unstable. At this time, the temperature information and the oil pressure information are adjusted until the evaluation coefficient is within the coefficient threshold. The evaluation model is expressed as: in, represents the evaluation coefficient, Indicates oil pressure information. Indicates temperature information. Indicates the oil pressure influence factor, represents the temperature influence factor, , .
