[0024] The embodiment is basically as shown in the attached Figures 1-8 Shown: An extruder, such as Figures 1-4 As shown, it includes a frame 1 and a barrel 5 and an extrusion drive device mounted on the frame 1. The bottom of the frame 1 is provided with a base plate 14, which is fixed to the ground. The barrel 5 is connected to a consistency measuring instrument, such as Figure 5 As shown, a feed port 16 is provided on the upper side of the barrel 5, and a hopper 6 is connected to the feed port 16. The hopper 6 has a structure that is larger at the top and smaller at the bottom. An extrusion drive device and a discharge port 15 are respectively provided on both sides of the barrel 5 in the horizontal direction, and the discharge port 15 is connected to the forming die. The extrusion drive device includes a rotating assembly, a forward-rotating feeding screw 7 and a reverse-rotating feeding screw 8. The forward-rotating feeding screw 7 and the reverse-rotating feeding screw 8 are arranged side by side and are rotatably connected in the barrel 5. The length direction of the forward-rotating feeding screw 7 and the reverse-rotating feeding screw 8 is the feeding direction of the barrel 5. The structure of the forward-rotating feeding screw 7 and the reverse-rotating feeding screw 8 is shown in FIG. Figures 6-8 shown.
[0025] The rotating assembly is used to drive the forward-rotating feed screw 7 and the reverse-rotating feed screw 8 to rotate in opposite directions. The rotating assembly includes a driving member 3, a first gear 12, a second gear 13, and a support assembly. The support assembly is mounted on the frame 1 and is used to support the forward-rotating feed screw 7 and the reverse-rotating feed screw 8 on one side extending out of the barrel 5. The support assembly includes a support base 10, which is provided with two mounting holes. Bearings 9 are fixed in both mounting holes.
