Grinding rotor with improved structure

Abstract

The invention relates to a rotor of a grinding machine, and in particular relates to a grinding rotor with an improved structure. The grinding rotor comprises a rotor body which is driven by a main shaft of the grinding machine and is provided with a plurality of rod pins; each rod pin comprises a grinding part and a connecting part which is arranged on the body in a detachable way; each connecting part is connected with the corresponding grinding part in a detachable way. The rotor body is connected with the rod pins in a detachable way, and each rod pin consists of the connecting part and the grinding part which are connected in a detachable way. After the rod pins are worn, screws are loosened, the grinding rotor can continue to work normally after the grinding parts are replaced, the grinding parts are convenient to replace, and the whole rod pins do not need to be replaced, so that the cost is saved; the grinding parts of the rod pins are made from silicon nitride, so that the rod pins are light in weight and better in wear resistance. One part of the rotor body is made from aviation aluminum, so that the mass of the whole rotor is further lightened on the basis that material pollution is not caused, the load of the rotor is reduced, and energy is saved.

Description

technical field [0001] The invention relates to a grinding rotor which is a core part of a nano grinding machine. Background technique [0002] The nano grinder has a wide range of applications and can meet GMP, food, pharmaceuticals, life sciences, microorganisms, ceramic glazes, oxides, inorganic pigments, ceramic inkjet, high-performance marine paints and anti-corrosion paints, lithium iron phosphate batteries, carbon Requirements for the use of nanometer materials such as nanotubes, electronic optical fibers, LCDs, and MLCCs. The grinding rotor of the nano grinding machine is generally driven by the main shaft, and the material in the grinding chamber is ground by the rotation of the rotor to drive the medium. Some of the existing grinding rotors are of disc type, some of them are of turbine type, and some are of pin-pin type. Most of the pin-type grinding rotors are equipped with pins on the hollow grinding rotor body. One end of the body is fixed on the main shaft, a...

AI Technical Summary

Problems solved by technology

This form has the following defects: 1. When the pin is worn out, the rotor formed by stacking ceramic rings must replace the entire ring; the rotor formed by the integrated rotor body needs to replace the entire pin or the main rotor. It is cumbersome to replace, wastes materials, and costs high; 2. The pin and the body are made of metal, PU and other materials. On the one hand, the weight of the entire rotor is heavier, the load on the main shaft is larger, and more power is consumed; On the one hand, the wear-resistant type of the rod pin is poor, and the service life is short. If it is not replaced in time, it is not ruled out that the product will be polluted after the metal is worn out, and the quality of the grinding product will be affected.
