Special feeding device for dry suspension

Abstract

The invention relates to a feeding device special for dry suspensions. The feeding device special for the dry suspensions is characterized in that a box body is composed of a metering plate with a metering tank, a left vertical plate, a right vertical plate, a rear vertical plate and a transparent front baffle, wherein supports with track idler wheels are installed at the left end and the right end of the upper surface of the metering plate respectively, an upper movable plate is supported on the top of the box body through the track idler wheels, a plurality of rotary shifting forks and a plurality of material blocking blocks are installed on the upper movable plate, and are inserted into the box body, the rotary shifting forks are connected with a micromotor through a chain drive mechanism, one end of the upper movable plate is connected with an output shaft of a servo motor through a left-and-right transmission mechanism, sliding unit bases are installed at the left end and the right end of the lower surface of the metering plate respectively, sliding rods are arranged in the sliding unit bases respectively, a lower movable plate is fixedly connected between the two sliding rods, feeding valves are arranged above the lower movable plate, and are connected with the lower movable plate through feeding hoppers, the upper surfaces of the feeding valves are closely attached to the lower surface of the metering plate, feeding ports are formed in the feeding valves, the feeding hoppers are communicated with the metering tank through the feeding ports, and the other ends of the sliding rods are connected with air cylinders. The feeding device special for the dry suspensions has the advantages of being accurate in feeding metering and free of powder leakage.

Description

technical field [0001] The invention relates to an automatic material filling device for a multi-row bag four-side sealing packaging machine, in particular to a special feeding device for dry suspension. Background technique [0002] At present, the problem of dry suspension feeding in multi-row four-sides-sealed packaging bags has always been a difficult problem in the packaging industry. Since the dry suspension material has the characteristics of a mixture of powder and granules, there will be leakage when filling with an ordinary granule feeder. Powder phenomenon, and feeding with powder will squeeze the material to crush the particles in the dry suspension, thereby changing the density of the material, which will lead to inaccurate loading. Therefore, there is an urgent need for a special feeding device for dry suspensions with accurate measurement and no powder leakage on the market. Contents of the invention [0003] The technical problem to be solved by the presen...
