Summary of the invention:
Technical problem to be solved in the utility model is: solve existing dynamic measurement belted electronic balance and bunker scale scale the body excessive and alleged material of deadweight or flow and hour cause measuring inaccurate problem, and provide a kind of simple in structure, cost is low, easy installation, reduce static bunker scale and belted electronic balance tare weight, overcome the external force influence, the magnetic suspension mechanism of the electronic measuring scale of damped vibration, raising measuring accuracy and stability.
The technical solution adopted in the utility model is: this magnetic suspension mechanism has one group or two or more sets permanent-magnet steels, every group of magnet steel is two permanent-magnet steels, be installed in respectively on the electronic measuring scale scale body and the conveyor frame on, perhaps two permanent-magnet steels are installed in respectively in two support bracket fastened magnetic steel sleeves, and two fixed supports are separately fixed on the electronic measuring scale scale body and the conveyor frame on.
The adjusting plug screw also is installed in the magnetic steel sleeve of above-mentioned installation permanent-magnet steel, regulates plug screw and magnetic steel sleeve screwed connection, regulate plug screw one end and hold out against magnet steel, magnetic steel sleeve also is equipped with fastening screw nut outward.
Two corresponding installations of magnet steel of above-mentioned every group of permanent-magnet steel, the abutting end polarity of two magnet steel is identical or opposite respectively.
Above-mentioned permanent-magnet steel can adopt neodymium iron boron to make.
Magnetic suspension mechanism of the present utility model is made of one or more groups neodymium iron boron permanent-magnet steel, every group of magnet steel is two, utilize the difference of its mounting means, be that polarity is identical or opposite, the power that its generation is repelled each other or inhale mutually, act on respectively on the weigher scale body and the conveyor frame on, to alleviate the deadweight of scale body, the range that makes force transducer not reason scale body tare weight is excessive and have to its range is selected too much, and influences measuring accuracy, and when the scale body is influenced by external force and produces impact shock, this magnetic suspension mechanism can effectively play damping action, thereby the utility model is skillfully constructed, and is reasonable in design, can improve the measuring accuracy and the quantification stability of electronic measuring scale, and it is simple in structure, cost is low, easily installs, and is particularly suitable for the dynamic measurement scale and the bunker scale of low discharge.
