[0019] In the following, only certain exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the following description is considered to be exemplary in nature rather than limiting.

[0020] Reference is made to Figures 1-3 In an embodiment of the degradable tableware edge material crushing device, the degradable tableware edge material crushing device comprises a shell 1, a rotating shaft 2 and a plurality of blades 3:

[0021] The shell 1 has a feed inlet 11 on one side of the top thereof, a discharge outlet 12 at the bottom thereof, and a screen 4 near the discharge outlet 12 in the shell 1, the outer periphery of the screen 4 being connected to the inner side wall of the shell 1; the lower end of the rotating shaft 2 is rotatably connected to the center of the screen 4 through a bearing with a seat, and the upper end of the rotating shaft 2 is connected to a driving motor 5, which is installed on the upper surface of the top of the shell 1 and coaxially connected to the rotating shaft 2 through a shaft coupling to drive the rotating shaft 2 to rotate at high speed; the plurality of blades 3 are fixedly connected to the rotating shaft 2 in a radial distribution with the rotating shaft 2 as the center, and are arranged in a spiral along the axial direction of the rotating shaft 2, and the side edge of each blade 3 opposite to the rotating direction of the rotating shaft 2 is serrated.

[0022] In use, the degradable tableware edge material to be crushed enters the shell 1 from the feed inlet 11 and is crushed into edge material particles by the blades 3, and the edge material particles fall from the discharge outlet 12 through the screen 4. The spiral arrangement of the plurality of blades 3 and the serrated design of each blade 3 can make the tableware edge material be crushed more uniformly.

[0023] As a preferred embodiment, the degradable tableware edge material crushing device further comprises a vibrating screen 6, a collection box 61 and a fan 62; the vibrating screen 6 is arranged directly below the shell 1, the input end of the vibrating screen 6 is aligned with the discharge outlet 12 to receive the edge material particles falling from the discharge outlet 12, and the aperture of the vibrating screen 6 is smaller than that of the screen 4 to further screen the edge material particles; the collection box 61 is arranged below the vibrating screen 6 to receive the edge material particles of the required particle size; and the fan 62 is connected to one side of the vibrating screen 6 and the other side of the top of the shell 1 through a pipeline to blow the edge material particles of the non-required particle size into the shell 1 for re-crushing.

[0024] As a preferred embodiment, the rotating direction of the plurality of blades 3 arranged in a spiral can be set opposite to the rotating direction of the rotating shaft 2, so that during the rotation of the blades 3, an axial force is generated on the edge material, which can push the edge material to move downward along the rotating shaft 2, so that the edge material is fully crushed.

[0025] As a preferred embodiment, the blades 3 are arc-shaped and curved towards the rotating direction of the rotating shaft 2, and the end of the blades 3 away from the rotating shaft 2 is close to the inner side wall of the shell 1. The arc-shaped design makes the contact between the cutting edge of the blade 3 and the edge material during the rotation of the blade 3 gradual; when the blade 3 starts to contact the edge material, it gradually cuts in from one end of the cutting edge, and as the blade 3 rotates, the entire cutting edge gradually contacts the material and completes the cutting. This gradual cutting method can cut the edge material more carefully, so that the particle size of the crushed edge material is relatively more uniform.

[0026] The use method or working principle of the utility model is as follows:

[0027] First, the biodegradable tableware edge material to be crushed is put into the shell 1 from the feeding port 11, the driving motor 5 is turned on to drive the rotating shaft 2 to rotate, the rotating shaft 2 drives the plurality of blades 3 to rotate, and the biodegradable tableware edge material is cut into edge material particles; the serrated blades 3 can increase the contact area and cutting force with the edge material during cutting, so that the edge material can be more easily broken into small pieces; the plurality of blades 3 are arranged in a spiral, so that the edge material can be more uniformly cut in the shell 1; after the edge material enters the shell 1, it will pass through the blades 3 at different positions in turn as the rotating shaft 2 rotates, so as to avoid the situation of excessive crushing or insufficient crushing in some parts, thereby further improving the uniformity of the edge material crushing.

[0028] The edge material particles crushed by the blades 3 fall through the screen 4 from the discharge port 12, are further screened by the vibrating screen 6, the edge material particles meeting the required particle size fall from the bottom of the vibrating screen 6 and are finally collected in the collection box 61, and the edge material particles not meeting the required particle size are blown by the fan 62 into the shell 1 for re-crushing.

[0029] The above is only a preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical scheme and utility model concept of the utility model within the technical range disclosed by the utility model, which should be covered within the protection scope of the utility model.
