The dust collecting system of the environmental protection polishing machine is composed of the interlayer of the protective cover of the working roll and the dust collecting ventilation pipe in the whole machine body to form a dust collecting cavity, and the induced draft fan discharges the dust from the pipe through the ventilation pipe. At the outlet of the inner pipe, the exhaust air volume is regulated by the valve, and the dust is discharged into the dust filter. The safety baffle is installed on the roll protection cover during the work. When the hand collides, the feeding roll returns to the non working position, and the main machine stops working. After the restart, the normal work can be resumed.

    The control panel and computer motherboard are controlled by single chip microcomputer respectively, which has the function of automatic frequency searching and locking; Five spark pulses and ninety-nine segments of lines and enhancement pulses are formed accurately by microcomputer. In the working state of lines, the lines from sub light to thick can be simulated realistically; Strengthening the working state can transfer tungsten carbide and other raw materials with high wear resistance to the working surface layer of the product workpiece, thus greatly extending the service life of the product workpiece; Due to the improvement of the acoustic output circuit, the machine is very suitable for vibration grinding of rough surface with fiber oilstone and diamond file; The voice prompt function of human voice with artificial intelligence is added, which provides a strong guarantee for the correct and safe use of the machine.
