[0022] By turning the hand wheel 35, the screw rod 34 is rotated, which makes the internal thread block 33 drive the limit plate 32 to translate along the axial direction of the screw rod 34, so that the movable plate 31 can slide inside the feed hopper 2. If the movable plate 31 slides outward, the amount of PP material raw materials introduced by the feed hopper 2 into the lower material box 1 will be increased. If the movable plate 31 slides inwardly into the feed hopper 2, the amount of PP material raw materials introduced by the feed hopper 2 into the lower material box 1 can be reduced, thereby realizing the adjustment of the discharge amount of the feed hopper 2, and effectively avoiding the problem of excessive accumulation of PP material raw materials in the stirring mechanism 4 affecting the stirring work.

[0023] Among them, a stirring mechanism 4 is arranged on the inner side of the material box 1, and the stirring mechanism 4 includes a rotating shaft 41, and the rotating shaft 41 is rotatably mounted on the top of the inner side of the material box 1, and a motor 42 is fixedly mounted on the top of the outer side of the material box 1, and the output shaft of the motor 42 is fixedly connected to the rotating shaft 41, and a plurality of stirring rods 43 are fixedly mounted on the rotating shaft 41, and the plurality of stirring rods 43 are evenly distributed along the axial direction of the rotating shaft 41, and an inclined material guide seat 44 is fixedly mounted on the bottom end of the inner side of the material box 1, and a material blocking member 45 for intermittently preventing the material from being discharged is arranged at the bottom end of the material guide seat 44;

[0024] Among them, the material blocking member 45 includes a partition 451, which is fixedly installed on the top of the inner side of the material discharge box 1, a cam 452 is fixedly installed at one end of the rotating shaft 41, and the cam 452 is located on one side of the partition 451.
