[0016] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0017] like Figures 1 to 4 As shown, the utility model can be implemented through the following embodiments: a novel extrusion granulator structure, including an auger 1 and a discharge head 2, a conical head 11 is arranged at the upper end of the auger 1, the conical head 11 extends into the discharge head 2, the conical head 11 extends into the discharge head 2, the discharge head 2 is conical, and the discharge head 2 is composed of a large end flange 21, a conical cover 22 and a small end flange 23, a conical cover 22 is installed between the large end flange 21 and the small end flange 23, and a cover plate 3 is installed on the small end flange 23.

[0018] The conical head 11 arranged at the upper end of the auger 1 is used to cooperate with the conical discharge head 2, so that the conical head 11 can be inserted into the discharge head 2 for installation. When the auger 1 is started, the auger 1 relies on centrifugal force to throw the material onto the discharge head 2 and extrude the material into shape. Since the distance between the auger 1 and the discharge head 2 is short and the force attenuation is small, the material can be evenly thrown onto the discharge head 2 and formed. The arrangement of the cover plate 3 facilitates the cleaning of the inside of the discharge head 2 after removing the lower cover plate 3.

[0019] like Figure 1 and Figure 4As shown, a shredder 111 is provided on the conical head 11, and the shredder 111 rotates in the opposite direction to the auger 1. The shredder 111 is provided to facilitate the material to be fully mixed at the discharge head 2, and at the same time provide another channel for throwing the material, so that the thrown material passes through the discharge head 2 more evenly.

[0020] like Figure 1 and Figure 2 As shown, a discharge hole 1 (221) is provided on the outer surface of the conical cover 22. The discharge holes 1 (221) are distributed all over the conical cover 22, thereby increasing the discharge area of ​​the discharge head 2 and improving production efficiency.

[0021] like Figures 1 to 3 As shown, the cover plate 3 is provided with a second discharge hole 31. The second discharge hole 31 is a supplement to the first discharge hole, and provides a passage for the material to pass when the auger 1 throws the material onto the cover plate 3, thereby reducing the accumulation of the material in the discharge head 2, ensuring uniform material discharge, and reducing waste.

[0022] like Figure 2 and Figure 3 As shown, an annular boss 231 is provided on the small end flange 23, and a matching annular groove 32 is provided on the cover plate 3. The annular groove 32 cooperates with the annular boss 231 to strengthen the seal between the small end flange 23 and the cover plate 3, preventing the material from being thrown onto the cover plate 3 and not flowing out through the discharge hole 1 and the discharge hole 2 31.

[0023] The working principle of the utility model is as follows: after the auger 1 is started, the auger 1 transports the material to the discharge head 2 and throws the material onto the discharge head 2 through centrifugal force. Since the rotation direction of the auger 111 is opposite to that of the auger 1, it is convenient to intercept the material thrown by the auger 1, and after sufficient mixing, it is thrown a second time, so that the material transported by the auger 1 is spread more evenly on the discharge head 2 and the cover plate 3.

[0024] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0025] Although various terms are used more frequently in this article, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
