Description

The cutter of the shredder

This creation is related to a shredder, especially a cutter of a shredder.

The demolition machine disclosed in the Republic of China Announcement No. M539985 patent uses multiple demolition cutter discs to rotate the material relative to the material, and during the rotary cutting, further utilizes the drawing section of the multiple demolition cutters to cut into the rotary cutting groove in a continuous longitudinal manner Inside, the material is rotated and cut into coarse and evenly distributed pieces.

Please refer to Figure 4 of the aforementioned patent case again, the conventional demolition cutter is a rectangular block in appearance, and the surface of the drawing section is presented in a planar manner, so that when the material is rotated, it is applied in a face-to-face manner Pressing on materials, if you want the cutter to produce a force that can tear the material, it must inevitably provide greater power to the cutter. In addition to the lack of processing efficiency, it will also cause more energy consumption. With the rise of energy saving awareness, There is still room for improvement in the structure of conventional tools.

The main purpose of this creation is to provide a cutter for a shredder, which can improve the processing efficiency and effectively save energy.

In order to achieve the above-mentioned main purpose, the cutting tool of this creation includes a drawing surface, a bearing surface facing away from the drawing surface, and a screw hole penetrating the drawing surface and the bearing surface, so that the tool uses a The bolt of the screw hole is installed on a knife seat of the demolition machine, wherein the drawing surface has a narrow upper and lower wide shape.

It can be seen from the above that the cutting tool of this creation uses the special shape of the cut surface, so that the cutting tool can reduce the load when crushing materials, so as to improve the processing efficiency of the cutting tool and save the energy consumption of the operation of the crusher.

Preferably, the drawing surface has a straight section and an oblique extension section, the straight section is penetrated by the screw hole, and the oblique extension section extends obliquely from the top of the straight section away from the bearing surface Moreover, this can further improve the processing efficiency of the cut surface.

Preferably, the cutter further has a positioning hole, the positioning hole penetrating the oblique extension section of the drawing surface and the bearing surface. Thereby, the cutter utilizes a positioning bolt provided in the positioning hole to increase the stability after being installed in the cutter base.

Preferably, the bearing surface further has a countersunk slot coaxially communicating with the positioning hole, the countersunk slot is used to receive the head of the positioning bolt.

Preferably, the cutter further has a top surface and two oppositely disposed shearing inclined surfaces, and a boundary between the top surface and the two shearing inclined surfaces forms a chamfer respectively.

The detailed structure, characteristics, assembly or use of the cutter of the demolition machine provided by this creation will be described in the detailed description of the subsequent embodiments. However, those with ordinary knowledge in this creative field should be able to understand that these detailed descriptions and the specific examples listed for implementing this creative are only used to illustrate this creative, not to limit the scope of patent applications for this creative.

The applicant first states here that throughout the specification, including the embodiments described below and the claims in the scope of patent application, the directional terms are based on the directions in the drawings. Secondly, in the embodiments and drawings to be described below, the same element numbers represent the same or similar elements or their structural features.

Please refer to FIG. 1. The demolition machine 10 shown in FIG. 1 includes a machine table 12, a knife shaft 14 and a plurality of knife holders 16, wherein the knife shaft 14 is rotatably provided on the machine table 12. A plurality of blade holders 16 are arranged side by side on the blade shaft 14 and can rotate together with the blade shaft 14. Since the structure of the demolition machine 10 is not the focus of this case, in order to save space, it will not be repeated here.

Please refer to FIG. 4 to FIG. 7 again, the cutter 18 of this creation has a top surface 20, a bottom surface 22, a broaching surface 24, a bearing surface 28, and two shearing surfaces 30, among which: the top surface 20 Opposite to the bottom surface 22, the cut surface 24 and the bearing surface 28 are front-to-back and both are narrow and wide, and the two shear surfaces 30 are opposite to each other. Further, as shown in FIGS. 4 and 5, The drawing surface 24 has a first straight extending section 242 and a first oblique extending section 244. The first oblique extending section 244 extends diagonally from the top of the first straight extending section 242 away from the bearing surface 28, so that the cutter 18 A convex portion 26 (as shown in FIG. 3) is formed at the portion corresponding to the first oblique extension section 244, and the bearing surface 28 is parallel to the first straight extension section 242 of the cut surface 24, as shown in FIGS. 4 and 5 The top and bottom ends of each shearing surface 30 are connected to the top surface 20 and the bottom surface 22 and have a second straight extending section 302 and a second inclined extending section 304, the second inclined extending section 304 is from the top of the second straight extending section 302 It extends diagonally toward the top surface 20 and forms a chamfer 32 with the top surface 20.

Please refer to FIGS. 4 and 5 again. The cutter 18 of the present invention further has a screw hole 34, a positioning hole 36 and a countersunk slot 38. The screw hole 34 penetrates the first straight extension 242 of the drawing surface 24 and the bearing surface 28. The positioning hole 36 is located above the screw hole 34 and penetrates the first oblique extension 244 of the drawing surface 24 and the bearing surface 28. The countersunk groove 38 is located on the bearing surface 28 and coaxially communicates with the positioning hole 36.

Please refer to FIGS. 2 and 3 again. When the cutter 18 of the present invention is used in conjunction with the tool holder 16, a positioning bolt 40 is first used to screw the positioning hole 36 of the cutter 18 to make the head 42 of the positioning bolt 40 Part of it is accommodated in the countersink 38, and then the exposed part of the head 42 is fitted into a positioning groove 162 of the knife holder 16, and finally a fixing bolt 44 is passed through a perforation 164 of the knife holder 16 and Locked in the screw hole 34 of the cutter 18 by screwing, so as to complete the assembly and fixation of the cutter 18. After the assembly is completed, the tool 18 abuts the tool holder 16 with the bearing surface 28 and spins the material into coarse pieces with the drawing surface 24 during the rotation with the tool holder 16.

It can be seen from the above that the cutter 18 of this creation uses the special shape of the drawing surface 24 to tear the material through the first oblique extension section 244 of the drawing surface 24 and then cut the material through the cutting surface 30 to avoid surface contact Pressure materials. In addition, the narrow and wide width above the drawing surface 24 can also produce the effect of less power applied to the tool in the case of the same tearing pressure, which will cause the tool shaft 14 to pass the tool seat 16 The driving cutter 18 can reduce the load when crushing the material, so as to improve the processing efficiency of the cutter 18 and save the energy consumption of the operation of the demolition machine 10, so as to achieve the purpose of this creation.
