The utility model is implemented through the following technical solutions:

The improved structure of the rubber block crusher tool mainly includes the body, the main shaft, the moving knife body, the moving knife, and the fixed knife. The fixed knife with adjustable position is installed on the body, and the moving knife is installed on the moving knife body. The keyway is fixedly connected to the main shaft through a flat key, and it is characterized in that there are multiple movable cutter bodies fixedly connected on the same main shaft, and the positions of the keyways on the movable cutter bodies are different.

The number of movable cutter bodies fixed on the main shaft is generally an odd number, and the position of the keyway of the first and last movable cutter body is usually set to 0°, and the position of the keyway of the second and penultimate movable cutter body is β °, the position of the keyway of the third and penultimate moving knife body is 2β°...and so on; the distance between any point on the same position of the cutting edge of the moving knife installed on the moving knife body The smooth connection forms a helix with a helix angle of β, and a special spiral triangular blade shearing structure is formed between the moving knife and the fixed knife.

The moving knife body is divided into multiple grooves equally along the circumferential direction, wherein a side wall on one side of the groove extends out a knife mounting surface.

The side wall on the other side of the groove is provided with a moving knife holding down bolt.

The blade portion of the movable knife is an angled blade.

The edge portion of the fixed knife is a toothed edge matched with the angular edge of the movable knife.

There are six grooves and six knife mounting surfaces on the moving knife body, and each knife mounting surface has a positioning screw hole for the moving knife.

The utility model has the following effects:

(1) The special structure of the moving knife body makes it possible to connect a piece of moving knife with an angular edge with the fixed bolt of the moving knife and the pressing bolt of the moving knife on each knife mounting surface. The combination of knives improves the cutting efficiency and saves energy consumption.

(2) The moving knife body installed with the moving knife is fixedly connected to the main shaft through the connection law of the flat key, so that the moving knife forms a special spiral triangular blade shearing structure; the motor drives the main shaft to run at high speed, so that the moving knife and the fixed knife The continuous cutting with spiral straight blade greatly improves the work efficiency, and this cutting method can effectively protect the tool and avoid major damage, thus prolonging the service life of the tool.

Detailed ways

Example

As shown in Figures 1, 2, and 4, the improved structure of the cutter of the rubber block crusher mainly includes a body 1, a main shaft 2, a movable cutter body 3, a movable cutter 4, and a fixed cutter 5. The movable cutter body 3 is divided into six parts along the circumferential direction. Each groove 8, wherein the side wall on one side of the groove 8 extends a knife-mounting surface 9, and each knife-mounting surface has a moving knife positioning screw hole 16; the side wall on the other side of the groove has a The screw hole 10 is used to install the moving knife pressing bolt 13, the positions of the key grooves 6 are different, and the key grooves 6 of each moving knife body are fixedly connected on the main shaft 2 through the flat key 7.

As shown in FIG. 5 , the blade portion of the movable knife 4 is an angular blade, and a movable knife positioning hole 11 is opened on it, and the movable knife 4 is fixed on the movable knife body 3 through a movable knife positioning bolt 12 .

As shown in Figure 3, the blade portion of the fixed knife 5 is a toothed edge cooperating with the angular edge of the movable knife 4, on which there are fixed knife positioning holes 14 and fixed knife positioning screw holes 15, and the fixed knife 5 with adjustable position Installed on the body 1 by bolts.

As shown in Figure 6, there are multiple moving cutter bodies 3 fixedly connected to the same main shaft 2, the number of moving cutter bodies 3 is generally an odd number, and key grooves 6 are formed on the moving cutter bodies 3, usually the first and last moving cutter bodies The position of the keyway of the cutter body is set to 0°, the position of the key 6 of the second and penultimate moving knife body is β°, and the position of the keyway of the third and third last moving knife body is 2β°... ...and so on for the rest; a special spiral triangular blade shearing structure is formed between the moving knife and the fixed knife; the motor drives the main shaft 2 to run at high speed, so that the moving knife 4 and the fixed knife 5 perform spiral straight-blade continuous shearing Cutting greatly improves the work efficiency, and this cutting method can effectively protect the tool and avoid major damage, thereby prolonging the service life of the tool.
