The present invention is arranged precompressed station and compacting station branch, adopt a precompressed to add the two stages of compression packaging method of a compacting, and employing casing and pressure plate structure, hopper and precompressed mechanism are integrated, after material is filled it up with hopper by setting weight, only need to shrink casing and can once finish precompressed work by pressing plate, and do not need additionally to be provided with the precompressed pressure heads mechanism, simplified device structure, reduced the complete machine height of equipment, make that the installation and maintenance of equipment are convenient, also more be tending towards hommization on the operating characteristics, also can effectively reduce tobacco leaf and make broken.
Further illustrate content of the present invention below in conjunction with the Figure of description and the specific embodiment.
Description of drawings
Fig. 1 is the structural representation of system of the present invention.
The specific embodiment
As shown in the figure, system of the present invention comprises precompressed mechanism 2 that is installed on the frame 1 and the system for compacting 3 that is positioned at precompressed mechanism 2 sides, above precompressed mechanism, be provided with feeding device 4, precompressed mechanism below is provided with carton positioner 7, described precompressed mechanism 2 is that whole liftable and outer container 2a can be along the flexible casing mechanisms of interior case 2b, but be provided with the pressing plate 2c of folding at the outer container 2a top of this casing, moving conveyor 5 below setting below the carton positioner 7 is movable to system for compacting 3, precompressed mechanism 2 and moving conveyor 5 are placed on the weighing device 6.Below precompressed mechanism 2, be positioned at moving conveyor 5 both sides and be provided with the conveying device of sending into the sky carton and sending tobacco bale.On the casing outer container 2a of precompressed mechanism 2, be connected with hydraulic pressure or pneumatic actuating device 2d.Be provided with jacking system in weighing device 6 bottoms.Shown in Figure 1 is to be provided with two precompressed mechanisms in the system for compacting bilateral symmetry, can realize the double precompressed, increases work efficiency.When adopting the double precompressed, the feeding device that is positioned at precompressed mechanism top also can adopt two-way distribution device, alternately is that two precompressed mechanisms are reinforced, increases work efficiency.
The course of work is as follows: start-up system, and system carries out initialization, and jacking system is in weighing device 6 jack-up upper, conveying device 8 is sent into empty carton on the moving conveyor 5, the back carton positioner 7 that puts in place descends, live carton surely after, under the driving of hydraulic pressure or pneumatic actuating device, chamber type precompressed mechanism 2 descends and inserts carton, subsequently, outer container 2a protrudes upward along interior case 2b, and it is upper that outer container 2a is in, interior case 2b is in the insertion cartons position, possesses the feeding state this moment.Pressing plate 2c in the precompressed mechanism 2 is opened, and feeding device 4 actions are reinforced in casing, and when being added to the weight of setting, feeding device stops to feed in raw material, and weighing device 6 falls, and pressing plate 2c closes, and outer container 2a moves downward, case 2b outside in being enclosed within.Along with moving down of outer container 2a, under the effect of pressing plate 2c, the smoked sheet of filling outer container 2a height and interior case 2b height originally is compressed to the height that has only interior case, thereby realizes the precompressed to smoked sheet.After precompressed put in place, moving conveyor 5 actions moved to system for compacting 3 times with the precompressed casing that smoked sheet is housed, and 2c opens with rear fender, and the pressure head of system for compacting presses down, with tobacco leaf compacting.After the compacting operation was finished, moving conveyor 5 actions were moved back into the precompressed position with the precompressed casing, subsequently, the precompressed casing is mentioned, and throws off carton, and the pressure head of system for compacting rises, and carton positioner 7 rises, conveying device 8 starts, and the tobacco bale of accomplishing fluently is sent, and empty carton is sent into.After new empty carton puts in place, repeat aforementioned activities, begin new carton vanning packing.Two precompressed mechanisms shown in Figure 1 can work simultaneously, alternately will finish precompressed casing after the precompressed and move to and carry out compacting under the system for compacting.
