The two-stage hopper in the raw material metering mechanism of rotary automatic packaging machine

摘要

PROBLEM TO BE SOLVED: To provide a two-stage hopper in a raw material-measuring/supplying mechanism of an automatic rotary packer which maintains a stable law material supply operation by inhibiting a variation in volume of a law material when the law material is supplied out of the hopper to a measuring rotary disk.;SOLUTION: The hopper in the raw material-measuring/supplying mechanism of the automatic rotary packer has a two-stage hopper structure, in which a support disk 38 having partition holes 42 narrowing a drop path is placed between two hoppers. The top of a second hopper has air adjusting holes 43 leading outside and blocking plates 41. These air adjusting holes 43 and blocking plates 41 adjust the volume of air discharged out of the second hopper 12, to adjust the reserving rate of the raw material that is dropped from a first hopper 11 into the second hopper 12.;COPYRIGHT: (C)2007,JPO&INPIT
