detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Figure 1-2, the utility model provides a technical solution: a high-efficiency plastic extruder, including a base 1, a crushing box 10 and a water tank 18, an extrusion box 2 is installed above the base 1, and an extrusion box 2 Extrusion screw 3 is installed in the interior of the extrusion box 2, and the inner wall side of the extrusion box 2 is provided with a heating wall 4. There are two heating walls 4, and the heating walls 4 are symmetrical about the horizontal centerline of the extrusion box 2. The heating wall 4 The colloid can be heated and melted. The first motor 5 is installed on the left side of the extrusion box 2, and the first motor 5 is rotationally connected with the extrusion screw 3 through the first rotating shaft 6. The upper right side of the extrusion box 2 is provided with a heating Electric furnace 7, and control panel 8 is installed on the top of heating electric furnace 7, and heating electric furnace 7 can provide heat source for heating wall 4 and preheating wall 16, and the right side of extruding case 2 is equipped with extruding die 9, and extruding die 9 The surface is a uniformly distributed pore-like structure, which can make the colloid extrude from the holes. A crushing shaft 11 is installed inside the crushing box 10, and the crushing box 10 is located above the extrusion box 2.
