Automatic grinding machine

Abstract

The invention discloses an automatic grinding machine. The machine comprises a circuit control system for controlling a grinding head of a stone grinding plate to be matched with a belt of a stone delivering plate, wherein the circuit control system comprises a first detection circuit, a second detection circuit, a first counting circuit, a second counting circuit, a first limiting circuit, a programmable controller (PLC), a plurality of first key trigger circuits, a second key trigger circuit, a human-machine operation interface, a first driving circuit, a second driving circuit, a third driving circuit, a fourth driving circuit, a fifth driving circuit, a polishing motor, a cross-bridge swing motor, a conveyor belt motor, a first cylinder electromagnetic valve and a second cylinder electromagnetic valve. The working state of a multi-stage grinding head can be accurately controlled by using the circuit control system, so that components of the entire grinding machine can be matched with one another to finish polishing slab stones. The machine has the characteristics of high automatic degree, high polishing degree of finish and good use effect.

Description

technical field [0001] The invention relates to a stone processing machine, in particular to an automatic stone grinding machine. Background technique [0002] Stone grinding machine is a kind of stone processing machine. In the process of stone processing, the stone is cut into a sheet with a certain shape. Then, the surface of the stone sheet needs to be polished to make the surface of the stone sheet reach the A certain flatness and brightness, and the process of polishing the surface of the stone sheet is processed by a stone grinder. Existing stone grinding machines are usually equipped with a grinding head, on which abrasive materials are installed, and the grinding head is driven by a polishing motor to rotate, and the abrasive on the grinding head rubs against the processed stone surface during rotation, thereby realizing the The surface of the processed stone is polished, because in the process of polishing the stone surface, the surface of the stone slab must be r...

AI Technical Summary

Problems solved by technology

For the hand-held stone grinding machine, it is necessary to constantly replace the grinding head to choose different abrasives to process the surface of the stone, which causes inconvenience in the processing process. At the same time, its quality is closely related to the proficiency of the operator. Ordinary operation Those who are often difficult to achieve better precision requirements; and for mechanical stone grinding machines, abrasives with different thicknesses can be installed on multiple grinding heads, and the abrasives are arranged into an assembly line from coarse to fine, so that the slate moves along the assembly line. Multiple grinding heads polish the stone slabs in sequence, which has the effect of automatic grinding. However, due to the reason of the circuit control system, the existing grinding stone machine cannot accurately control the grinding process, resulting in the polishing process. The slate cannot achieve the required polish
