The utility model discloses a working process and principle do: the hopper is filled with materials to be filled, when the conversion valve core is in a metering state, the first channel of the conversion valve core is communicated with the hopper and the metering cylinder, the metering piston descends to a preset position under the action of a power source through the metering pull rod, the materials in the hopper are sucked into the metering cylinder to finish quantitative suction of the materials, and at the moment, the lower end of the switch valve core is in a sealed closed state (as shown in figure 3) with the lower end of the inner wall of the filling head in a joint mode, so that the materials in the switch valve core and the second channel cannot be sucked backwards; after the ration suction material finishes, the conversion pull rod is down under the drive of power supply, through connecting rod pulling conversion case rotation, make first passageway rotate to horizontal position, first passageway and charging duct intercommunication this moment, second passageway and measurement jar intercommunication, the measurement piston goes upward under the drive of power supply, and simultaneously, switch valve core goes upward under the switch drive, switch valve core lower extreme and filling head inner wall lower extreme are kept away from, the filling passageway is opened (as shown in fig. 5), the material that the measurement was accomplished flows out through second passageway and first passageway and fills the container the inside through the filling head. When the material is inhaled for the second time, the conversion pull rod rises, the conversion valve core is rotated to a metering state through the rocker arm so as to start the next quantitative material suction, the cylinder pushes the valve core of the switch valve body to move downwards so as to close the filling head, and the processes of quantitative material suction and extrusion feeding are completed in a circulating reciprocating mode.

The utility model provides a filling tail-sealing machine quantitative filling mechanism, its conversion case simple structure, and the measurement degree of accuracy is high, and the supporting of sliding leads to the conversion pull rod through the guide pin bushing that sets up, makes reciprocating of conversion pull rod smoothly stable, and the rotational position uniformity that makes the conversion case in coordination with the connecting rod is good, through the switch valve body that sets up, effectively prevents to inhale the material of material in-process switch case and second passageway can not by the suck-back, is favorable to promoting the precision of measurement filling.
