Feeding machine

The invention discloses a feeding machine. The feeding machine comprises a base (1), a guide rail (2), an adjusting sliding block (3) and a rack (4), wherein the upper surface of the base (1) is parallel to the horizontal plane, the end, close to an extruder, of the base is the first end, and the end, away from the extruder, of the base is the second end; the guide rail (2) is fixedly arranged on the upper surface of the base (1), and the first end of the base (1) extends to the second end; the adjusting sliding block (3) is arranged on the guide rail and moves along the guide rail (2); and the bottom end of the rack (4) is fixedly arranged on the adjusting sliding block (3), and a feeding mechanism (5) is arranged at the top end of the rack (4). The feeding machine achieves the purpose that mounting and debugging are just needed once during the butt-joint assembly of the feeding machine and the extruder, and the trouble that during multiple times of assembly and adjustment, positioning is difficult due to th
