Novel cutting tool for tyre crusher

Abstract

The invention relates to a novel tool of a tire crusher, which is mainly used for cutting waste tires into blocks. The tool comprises two shaft levers (1) which are arranged in parallel; a plurality of blades (2) are tightly sleeved on each shaft lever (1); each blade (2) comprises a blade body (2.1) and blade teeth (2.2) arranged on the outer edge of the blade body (2.1). The tool is characterized in that the blade teeth (2.2) of the plurality of blades (2) are in helical arrangement on the shaft levers (1), and the blades (2) on the two shaft levers (2) are in bilateral symmetry arrangement. The tool has the advantages of small contact area of blade edge when the tire is cut, high cutting efficiency, replaceable blade teeth of the blades, and long service life of the blades.

Description

technical field The invention relates to a tire shredder, in particular to a novel tire shredder cutter. It is mainly used to crush waste tires into lumps. It belongs to the technical field of tire crushing machinery. Background technique The tire shredder cutter is the main part of the whole tire shredder. It is mainly composed of two parallel shafts and several blades tightly fitted on the two parallel shafts, as shown in Figure 1. The two shafts rotate inwardly in opposite directions to bring the rubber block fed on the upper part between the two shafts into the corresponding two blades on the two shafts for cutting. The disadvantages of this installation method are: 1. Several blades are arranged in a straight line on the shaft, and several blades cut at multiple points at the same time, resulting in a large blade edge contact surface when the entire tool is broken. Damaged motors, electrical appliances and other original components, so the safety and reliability a...

AI Technical Summary

Problems solved by technology

1. Several blades are arranged in a straight line on the shaft, and several blades cut at multiple points at the same time, resulting in a large blade edge contact surface when the entire tool is broken. Damaged motors, electrical appliances and other original components, so the safety and reliability are poor

2. The two cutting surfaces at the cutting edge of each blade are beveled, and the cutting is only one-way cutting, and the cutting efficiency is low

Time-consuming and affect production

4. The tooth part and the blade body part of each blade are made of ordinary steel surfacing alloy, and its surface hardness does not exceed HRC62, while the tooth part is the easiest to wear, and the blade needs to be replaced as a whole after wear, and the service life of the blade is short
