The moving devices are two, the leaf stalks and the fragments respectively enter the movable workbin 10 from the positions, corresponding to the two side working areas, on the top bearing platform 2, and the middle working area is used for pre-pressing the leaf stalks or the fragments in the paper boxes 10.

And the lifting oil cylinder 13 is arranged in the middle working area and fixed on the rack 1, when the mobile device moves to the middle working area, the lifting oil cylinder 13 is matched with the extension part 12 to vertically lift the movable material box 11, and the bottom outlet of the movable material box 11 is ensured to be separated from the paper box 10 positioned at the bottom of the weighing frame 8. A bearing platform is arranged on the ground of the middle working area and at the position corresponding to the weighing frame 8, and a positioning device 17 is arranged on the bearing platform. When carrying out the pre-compaction process, weighing cylinder 1000 falls weighing frame 8 on load-bearing platform, is fixed a position by positioner 17 weighing frame on the load-bearing platform, and the carton conveyer of 8 installations of weighing frame is supported to the load-bearing platform to carry out the pre-compaction. The middle working area can be provided with a carton conveying track which is butted with the carton conveyor of the weighing frame 8.

When the device is used, one of the two moving devices is in a blanking process, and the other moving device is in a pre-pressing process. The working process of the moving device in the blanking process is as follows: the moving device is located in a side working area on one side of the side, the weighing cylinder 1000 slightly lifts the weighing frame 8 to enable the weighing frame 8 to be in a suspended state, a carton 10 is already placed at the bottom of the weighing frame 8 (an empty carton is placed in a pre-pressing process, an outlet of the movable bin 11 is located in the carton), the weighing device 9 can weigh the carton according to the weight difference, then a feeding mechanism located on the top bearing platform 2 conveys and drops materials (one of leaf stems or fragments) into the carton at the bottom from the top of the movable bin 11 and accumulates the materials in the movable bin 11, when the amount of the materials in the movable bin 11 reaches 97-98.5% of the set weight, the feeding mechanism changes to slow feeding, when the slow feeding reaches 99% -99.5% of the set weight, the feeding mechanism stops storing (the value of the set weight can be set according to the specific situation of the actual materials coming), at the time, the blanking process is completed, after the moving device located in the middle working area moves to one side, the moving device of the carton 10 loaded with the materials moves to the middle working area, and moves to the top of the movable bin 11 relatively to the top of the movable bin 6.

The working process of the prepressing procedure comprises the following steps: after the moving device moves to the middle working area, the weighing cylinder 1000 adjusts the height of the weighing frame 8, adjusts the weighing frame 8 from a suspended state to be placed on the bearing platform, and is positioned by the positioning device 17. Although the weighing frame 8 is lowered to a certain height as a whole and the movable bin 11 is relatively unchanged in height, a large part of the material still remains in the movable bin 11, because if the material is fully in the carton 10, it is obvious that the compression of the material will damage the box. After the process is finished, the assembly hydraulic cylinder 5 controls the pressure head 6 to descend. The ram 6 can be divided into four stages in the pressing process, namely a free fall stage, a rapid pressing stage, a slow pressing stage and a pressure maintaining stage. A free fall stage: at the initial stage of descending of the pressure head 6 and the stage of relatively small tobacco density, the pressure head does not have material resistance when descending, because the weight of the pressure head, the piston rod, the guide rod and the like is relatively large, the pressure head 6 does approximate free-fall motion after overcoming the friction resistance of the sealing ring of the oil cylinder when descending, the oil supply of a pump station and the oil return of a lower cavity cannot meet the requirement of the upper cavity of the oil cylinder, the upper cavity of the oil cylinder has negative pressure, and at the moment, the top oil supplementing tank supplies oil to the upper cavity of the oil cylinder quickly. Therefore, the oil cylinder has high running speed at this stage, the packing period is greatly shortened, and the production efficiency of the whole machine can be effectively improved. And (3) a quick pressing stage: because the material is compressed, the descending resistance of the pressure head is continuously increased, when the resistance is equal to and is further greater than the weight of the pressure head and the piston rod, the pressure of the upper cavity of the oil cylinder is converted into positive pressure, namely the pressure head can push the piston by depending on pressure oil if going down continuously. At this point, the make-up tank is no longer providing oil and the ram is moving down at a relatively fast rate, so this phase is referred to as the rapid pressure phase. And (3) a slow pressure stage: when the material is compressed to a certain degree, the resistance of the pressure head to be pressed down becomes large, and at the moment, the pump station unloads the oil pump B2 and the oil pump B1 provides pressure oil, so that the pressure head is continuously pressed down at a slow speed. And (3) pressure maintaining stage: when the pressure head 6 is pressed to a specified size, the pressure head 6 stays for a period of time to prevent the rebound quantity of the materials from being too large, and the period is called a pressure maintaining period. The length of the pressure maintaining time depends on the type of the material, the moisture content and the weight of the material, and can be set according to the actual situation.

After the pressure maintaining is finished, the movable material box 11 is lifted by the box lifting oil cylinder 13, when the movable material box 11 is lifted to a height that is about 200mm higher than the lower plane of the pressure head 6 (about 800mm, the height is adjustable), the lifting is stopped, and the pressure head 6 starts to lift. The pressure head 6 is ascended in three stages, the pressure head is ascended slowly, the ascending distance is about 200mm to 350mm, then the pressure head stays for 2 to 3 seconds, and the blowing is carried out by the nozzle 15. The second stage, the fast-up stage, can be achieved after the pressure head 6 is separated from the tobacco leaves. When the pressure head 6 rises to about 150mm before the upper end point, the speed is changed to the third stage, and the process is stopped until the upper end point. When the press head 6 is changed from slow to fast, the movable material box 11 starts to be lifted continuously until the upper end point stops, and the movable material box 11 is ensured to be completely separated from the paper box 10. The prepressed paper box can be conveyed to the next station through the conveying belt, and meanwhile, the empty paper box is conveyed into the next station through the paper box conveying mechanism. When the empty carton is conveyed in place, the movable material box 11 begins to descend (if the carton is packaged, the carton positioning mechanism descends first, and the movable material box 11 descends after the carton is in place), the weighing cylinder 1000 lifts the weighing frame 8, the weighing frame 8 is suspended, the gross weight of the carton can be weighed, a signal with feeding conditions is sent out, the moving mechanism located in the middle working area is moved to the lateral working area through the reciprocating trolley 7 to perform a blanking process, and the process is circulated. Blanking and prepressing can be carried out simultaneously, feeding can also be two, and work efficiency is higher.

The positioning device 17 mainly comprises a stop cylinder 20, wherein a chuck 21 is arranged on the stop cylinder 20, and the chuck 21 inclines inwards through a pin shaft. The four stopping cylinders 20 are arranged, and correspond to the four corners of the weighing frame 8 respectively. When the weighing frame 8 is located above the chuck 21 and continuously falls, the weighing frame 8 is in contact with the chuck 21 to be guided, and two channel steel side plates of the carton conveyor below the weighing frame 8 are in contact with the stop cylinder 20 to be in contact with the bearing platform and transfer the weight to the bearing platform.
