The implementation principle of the negative pressure dust-free feeding and conveying device is as follows: the pumping fan 11 pumps graphite powder through the input pipe 13 in a negative pressure mode, and the graphite powder is conveyed into the cylinder body 311 through the pumping pipe 12 and the conveying pipe 14, most of the graphite powder can be settled in the cylinder body 311, and a certain amount of graphite powder can be temporarily stored in the cylinder body 311;
when the conveyor belt 7 transports the charging basket 8 to the lower part of the hopper 21, the driving source 41 is started to enable the sliding block 42 to move downwards, and meanwhile, the cleaning brush 51 can be driven to brush off graphite dust adsorbed on the inner wall of the barrel 311. The sliding block 42 opens the opening and closing plate 32 through the connecting rope 46, and the sliding block 42 moves the feeding barrel 23 downwards into the charging barrel 8 through the connecting piece 45, so that graphite powder is fed into the charging barrel 8;
the exhaust fan 62 is started to re-suck and convey the graphite dust generated in the charging basket 8 into the input pipe 13, so that the condition of the graphite dust in the charging basket 8 can be reduced. Then the driving source 41 drives the sliding block 42 to move upwards, and synchronously drives the material conveying cylinder 23 to move upwards until the graphite powder is filled in the material barrel 8.
The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
