The following explains the working principle of an embodiment of the tobacco shred boxing system of the utility model:

as shown in fig. 1, the cut tobacco packing system includes a first production line 10 (indicated by line 1) and a second production line 20 (indicated by line 2), which alternately perform the cut tobacco packing operation.

For example, in the related art, the flow of the tobacco shred boxing system is as follows: in the process of filling the cut tobacco with the No. 1 line, the No. 2 line completes cut tobacco compaction → pressure head recovery → material head recovery → solid box capping → full box moving out → next empty box in place → cap taking → hopper 31 moving downwards → filling, and the steps are repeated in this way to complete batch cut tobacco filling. In the process, cap taking and capping are carried out at the same station, and before the next empty box enters, the next empty box can enter only after the processes of cap removing, wire loading, compacting and capping of the last box body 50 are completed.

Specifically, in the related art, the time consumed by each link in the tobacco shred boxing process is as follows:

1. the moving-out of the previous solid box needs 6s, the moving-in-place of the next empty box needs 6s, and the total time is 12 s;

2. taking down the box cover 60 on the empty box for 8 s;

3. it takes 3s for the hopper 31 to move down to the position;

4. tobacco shreds are boxed, calculated according to the boxing flow of 11000kg/h, 180kg of tobacco shreds can be loaded in each box body 50, and the total time consumed when an empty box is filled is 58.9 s;

5. the time for compacting the tobacco shreds is 15s, the pressure maintaining time is 10s, and the total time is 25 s;

6. the total recovery time of the pressure head is 15 s; meanwhile, the recovery time of the hopper 31 is 3 s; the capping and uncapping device 40 returns to the original station with the cap and caps, and takes 8 seconds.

The three operations of recovering the ram, recovering the hopper 31 and capping can be performed simultaneously, that is, the hopper 31 can be lifted simultaneously in the process of lifting the ram, the ram is lifted for 9s, the capping can be started by the capping and decapping device 40 when the ram is lifted away from the box top, and the time is 8s (including the process that the capping and decapping device 40 returns to the boxing station 1s, the capping is performed for 6s, and the capping returns to the initial position 1s), so that the total time of the three operations of recovering the ram, recovering the hopper 31 and capping is 9s +8s which is 17 s.

Thus, the time consumed to assist in binning each flow can be calculated as:

firstly, moving out the full box, and taking 12s when the empty box is in place;

② the time consumed for taking the cover is 8s (including the step of adding the cover removing device 40 to enter the boxing station for 1s, the step of taking the cover for 6s,

covering back to the initial station 1 s);

thirdly, the hopper 31 moves downwards to the position for 3 s;

fourthly, the compacting time is 25s (including 15s of pressing head and 10s of pressure maintaining time);

fifthly, recovering the pressure head, recovering the hopper 31 and covering the original station for 17 s.

Therefore, the total time for auxiliary boxing is as follows: 12s +8s +3s +25s +17s ═ 65s

According to the specification of the tobacco shred boxes, 180kg of tobacco shreds are packed in each box, 61.1 boxes can be packed per hour according to the flow requirement of 11000kg/h (11000kg/h divided by 180 kg/box is 61.1 boxes/h), and the time consumed for packing each box is 58.9s (3600 seconds divided by 61.1 boxes is 58.9 seconds/box). If the total time of the auxiliary packing is 65s, the machine is stopped for waiting about 6s (the auxiliary packing time is 65s minus the tobacco shred filling time is 58.9s) before the next packing can be carried out.

In order to ensure the continuity of the boxing, the boxing time and the auxiliary boxing time should be equal, so that the feeding device 30 is prevented from stopping and waiting. If the tobacco shred filling time and the auxiliary boxing time are 65s and the boxing speed is reduced to 3600/65 x 180 kg/box-9969 kg/h according to the specification of 180 kg/box, the boxing speed is reduced to ensure the continuity of boxing.

The reduction of the packing speed will inevitably affect the reduction of the production efficiency. The inventor finds that in order to ensure that the boxing speed can meet the requirement and ensure the boxing continuity, the boxing mode can be improved, and the auxiliary boxing time is reduced, so that the auxiliary boxing time is not more than 58.9s of the tobacco shred filling time.

To achieve the above object, the inventors propose an improved tobacco shred packaging system. The improved core of the system is as follows: after the empty box is filled with the cut tobacco, the compaction device leaves the box top, the capping and uncapping device 40 does not need to take the box cover 60 to return to the original boxing station for capping, but the empty box is filled with the cut tobacco and then leaves the original boxing station for capping to another station, so that the capping time of 8s can be reduced.

The specific process of the embodiment of the application is as follows:

after the empty box is filled with the cut tobacco at the first station 11, the empty box is moved out of the first station 11 to the second station 12, and the capping is finished at the second station 12; meanwhile, after the cigarette box moves out of the first station 11, the next empty box can enter the first station 11. That is, the empty box can be removed from the first station 11 after it is filled, without waiting for capping to be completed, and therefore the auxiliary packing time is equivalent to 8 seconds required for capping operation.

The embodiment of the utility model provides an in, supplementary vanning each procedure consuming time do:

covering back to the initial station 1 s);

thirdly, the hopper 31 moves downwards to the position for 3 s;

and fifthly, recovering the pressure head for 9s, enabling the hopper 31 to simultaneously ascend in the ascending process of the pressure head, enabling the solid box to leave the first station 11 when the pressure head ascends for 9s and leaves the box top, and continuously ascending the pressure head. After the solid box leaves the first station 11, the next empty box enters, i.e. the flow of the first step.

It can be seen that the total time for auxiliary packing is 12s +8s +3s +25s +9 s-57 s

In summary, the auxiliary packing time is 57s according to the requirement of filling 180kg of cut tobacco in each box, and if the full time of each box can also be increased to 57 s/box, the single-box packing period is 57s +57 s-114 s, so that the packing capacity can be increased to 3600/57, 180 kg-11368 kg/h. And in the correlation technique, if supplementary vanning time is 65s, the vanning ability is 9969kg/h, and is visible, adopts the embodiment of the utility model provides a vanning system can effectively improve reinforced flow, improves vanning efficiency.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention and not to limit it; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the utility model discloses a do not deviate from under the prerequisite of the principle, still can be right the utility model discloses a specific embodiment modifies or carries out the equivalent replacement to some technical features, and these are modified and should be covered with the equivalent replacement in the middle of the technical scheme scope of the utility model.
