Double-cylinder extruder capable of controlling extrusion length of rice noodles

The invention discloses a rice noodle extrusion length controllable double-cylinder extruder, and relates to the technical field of extruders, the rice noodle extrusion length controllable double-cylinder extruder comprises an extruder body, extrusion heads are symmetrically arranged on the right side of the extruder body, a plurality of discharge ports are formed in the bottom ends of the extrusion heads, a mounting plate is fixedly connected to the right side of the extruder body, and a sliding rod is slidably connected to the right side of the mounting plate; the right side of the sliding rod is fixedly connected with two pushing blocks, the sliding rod slides left and right to drive the two pushing blocks to push the U-shaped sliding rod to slide left and right, and due to the fact that the distance between the two pushing blocks is larger than the length of the U-shaped sliding rod, the U-shaped sliding rod can only slide leftwards or rightwards for a period of time, and then the pushing blocks can drive
