The group number of described blanking shop foliar spray mouth and material level photoelectric tube is determined by hopper height and sheet plume amount.
The concrete quantity of described charging homocline nozzle is determined by hopper width and sheet plume amount.
The concrete quantity of every group of blanking shop foliar spray mouth is determined by hopper width and sheet plume amount.
The compressed-air actuated pressure limit that charging homocline nozzle and blanking shop foliar spray mouth use is 0.4MPa-0.6MPa.
Advantage of the present utility model is:
1. adopt prepressing device of the present utility model to carry out Tobacco slice packing, can exempt the mutual interference that mechanical system may exist between mechanical type cloth impeller and the pressure head when pressure head presses down, avoid the control lag of mechanical type cloth impeller simultaneously and the secondary material distributing that causes is inhomogeneous or cause the Density Distribution of sheet cigarette in case to form bigger deviation.
2. adopt this prepressing device can make material more uniform uniform and material dropping process is controlled in hopper, it is even to help in the guard box density.
3. the pneumatic material homogenizing method of utilizing this device to carry out can reduce sheet cigarette temperature of charge, reduces that Tobacco slice packing is laggard goes into drying in the air the bag time of storehouse.
