The medium in the inner cavity formed by the fixed rod (6035) and the abutting rod (6034) can be transmitted to the inner cavity formed by the other set of fixed rod (6035) and the abutting rod (6034) through the connecting pipe (6036), so that the abutting rods (6034) at the adjacent positions of the two roller components (603) expand and contract, realizing the further extrusion of the material located between the two roller components (603); Step S4: The two ends of the tension spring (6033) are respectively fixedly assembled with the inner wall of the end of the chute (6032) and the end of the abutting rod (6034), so that the tension spring (6033) pulls the abutting rod (6034). After the abutting rod (6034) is squeezed, the tension spring (6033) pulls the abutting rod (6034) to shrink the abutting rod (6034). The shrinkage and expansion process of the abutting rod (6034) is utilized to remove the material adhered to the outer wall of the abutting rod (6034) through scraping between the abutting rod (6034) and the inner wall of the chute (6032); Step S5: overlapping the outer wall of the first abutting shaft (6064) and the outer wall of the roller body (6031), so that the force in the middle of the roller assembly (603) can be transmitted to the first abutting shaft (6064), thereby increasing the service life of the roller assembly (603); Step S6: After being squeezed by the roller assembly (603), the material is discharged through the bottom of the protection cabin (604).
