It is connected with electromagnetic valve, the conveying roller platform where rites are performed is correspondingly arranged at the lower section of lower hopper, and the transfer passage is connected to lower hopper
Bottom, and with the intimate surface contact of conveying roller platform where rites are performed, the weighing unit includes weigh upper mounting plate, base station of weighing, elasticity
Support element and displacement resistance adjustment device, the upper mounting plate lower part connection elastic supporting member for supporting optical member of weighing, the bottom of elastic supporting member for supporting optical member connects
It is connected to base station of weighing, the displacement resistance adjustment device includes to be fixed on the conductive displaced block for upper mounting plate of weighing and be fixed on title
Variable resistance fixed seat on weight base station, the conduction displaced block is mutually powered with variable resistance fixed seat to be connect, and the variable resistance fixed seat is same
When connect with servo motor and electromagnetic valve circuit.Dust dissipation is had during the conveying of powder, in order to improve safety,
It, can be to upper mounting plate of weighing after powder constantly increases on weighing unit during blanking by the way of weighing automatically
Pressure is generated, after increasing the desired value of setting, displacement resistance adjustment device generates electric signal, servo motor and solenoid valve
Door is after obtaining electric signal, and the controlled operation for stopping servo motor and electromagnetic valve are closed, and powder stops blanking, and conveys
Roller platform stops feeding, and worker is transported through by the material for completing to weigh, in the processing after putting into.
Further, the surface of the variable resistance fixed seat is connected with the resistor disc that resistance gradually becomes larger in turn from top to bottom,
The bottommost of the variable resistance fixed seat is connected with insulator, and the conduction displaced block surface is connected with conductive sheet.It is upper flat weighing
During platform constantly declines, the electric current in variable resistance fixed seat can reduce because resistance during the decline constantly increases,
Therefore the rotating speed of servo motor can be slack-off, while electromagnetic valve is closed after insulator in the contact of conductive displaced block, and lower hopper is most
Stop blanking eventually, send roller platform also out of service.
Further, preventing clogging up device is installed, the preventing clogging up device includes to be transversely mounted in the lower hopper
Rotation axis is connected with stirring sheet in the rotation axis.The continuous rotation of stirring sheet can prevent powder adhesion, stifled in lower hopper
Fill in material mouth.
Further, the side elevation of the transfer passage is flexible material, the opening spacing of the front of the transfer passage
It gradually reduces.Opening gradually collapses, and reduces the dissipation of dust.
Further, the surface of the conveying roller platform where rites are performed is connected with scraper plate, and the inclination is arranged and is tightly attached to transmission
The lower part of roller platform front end.Scraper plate can strike off the powder not fallen on conveying roller platform where rites are performed, prevent powder from leaking.
Compared with prior art, the present invention haing the following advantages and effect：Dust is had during the conveying of powder to dissipate
Ease, in order to improve safety, during blanking by the way of weighing automatically, powder constantly increases on weighing unit it
Afterwards, pressure can be generated to upper mounting plate of weighing, after increasing the desired value of setting, displacement resistance adjustment device generates electric signal,
Servo motor and electromagnetic valve are after obtaining electric signal, and the controlled operation for stopping servo motor and electromagnetic valve are closed, powder
Stop blanking, and conveying roller platform where rites are performed stops feeding, worker is transported through by the material for completing to weigh, the processing after putting into
In.
