Description
Technical Field
The invention relates to a tobacco packing method and a tobacco packing device, and belongs to the technical field of tobacco packing.
Background
At present, in threshing and redrying production enterprises, in order to compress loose tobacco flakes after redrying into tobacco stacks with the weight of 200Kg for one time, 200Kg of loose tobacco leaves need to be loaded in a bin for one time, the stacking height of the bin is 6-8 m, so that the volume of the bin is huge, the height of the whole machine is higher, and the height of the whole machine is generally more than 19 m. The current tobacco packing equipment has higher requirements on factory investment, installation, use and maintenance, and the packing efficiency is lower. In addition, the blanking height of the equipment is too high, so that the blanking is uneven easily in the blanking process.
Along with the increasing requirements of equipment on the aspects of environmental protection, energy conservation, consumption reduction, humanized design and the like, and the improvement and the updating of equipment of tobacco leaf threshing and redrying enterprises, the method and the equipment which are easy to install and maintain and convenient to operate, compress and package are urgently needed to be provided. Patent CN107380575A proposes a tobacco leaf compression and blocking case packer, which divides a case of tobacco leaves into a plurality of parts, directly compresses and forms the parts and packs the parts, and the tobacco blocks in the case are divided into a plurality of pieces by the method, thereby destroying the integrity of tobacco stacks and being not beneficial to the storage and alcoholization of tobacco leaves.

(3) pushing into a main material box: pushing the primary-pressure cigarette stack obtained in the step (1) into a main material box by using 500-1500N;
(4) repeating the steps (1) to (3) until the primary pressure cigarette pile of the main material box reaches 200 kg:
(5) repressing, namely repressing the primary-pressure cigarette stack obtained in the step (4) by using 2000-;
(6) conveying: and conveying the tobacco leaves after re-pressing to the next station through a conveying device.
The compression ratio of the step (2) is the volume ratio of the primary pressed tobacco pile to the loose tobacco leaves, and the compression ratio of the step (5) is the volume ratio of the re-pressed tobacco pile to the primary pressed tobacco pile.
A device for the method comprises a main material box 3, primary pressure devices 1 arranged on two sides of the main material box 3, a moving device 5 arranged at the bottom of the main material box 3 and a conveying channel 4, wherein the conveying channel 4 is arranged at the top of the main material box 3, a movable baffle 4-1 is arranged at the bottom of the conveying channel 4, a main pressure head 2 is arranged above the conveying channel 4, a movable sliding door 3-1 is arranged on one side of the main material box 3, a movable material receiving plate 3-2 is arranged in an inner cavity, and the movable sliding door 3-1 and the movable material receiving plate 3-2 are connected with a vertical driving device 3-3.

When the device is used, the weighed tobacco leaves are conveyed to the primary pressing boxes on two sides by the conveying equipment, the pressing plates above the primary pressing boxes move downwards under the driving of the driving device, the tobacco leaf volume is compressed to 1/2-1/5 of the tobacco leaf volume in a loose state, the pressure of the pressing plates is in 1000 + 10000N, after primary pressing is completed, the movable partition plate between the primary pressing box on one side and the main box moves upwards, so that the primary pressing box on one side is communicated with the main box, and the pushing device pushes the primary pressing tobacco stacks to be pushed to the movable partition plate through the connecting channel. The movable sliding door and the movable material receiving plate on the main material box are lifted to the highest position through the vertical driving device, and the height of the movable material receiving plate is slightly lower than that of the movable baffle plate.
After the first stack of initial-pressed tobacco stacks is conveyed to the proper position, the material pushing plate returns to the initial position, the movable partition plate moves downwards, and the channel is closed. At the moment, the movable sliding door and the movable receiving plate on the main material box and the first stack of primary-pressure cigarette stacks descend by the height of the primary-pressure cigarette stacks. The movable baffle between the main material box and the connecting channel is reset, the primary material pressing box on the other side repeats the actions until a plurality of stacks of primary pressed tobacco stacks reach 200kg, the main pressure head presses downwards to complete the forming compression of the tobacco stacks, and the pressure head pressure is 2000 plus 20000N at the moment. The main pressure head is pressed down by using 2000-20000N pressure, so that the volumes of the tobacco stacks after being pressed again and the tobacco stacks after being pressed initially are 1/2-1/10, and the compression is completed.
After compression is completed, the belt surface of the belt conveyor rises to the bottom of the main material box under the action of the lifting driving device, the movable material receiving plate moves transversely to move out of the bottom of the main material box, the tobacco bale falls onto the belt conveyor, and the belt conveyor moves downwards and is conveyed to the next station.
The tobacco flake is pre-pressed for one time, so that the volume of the tobacco flake is greatly reduced through one-time pre-pressing, and the tobacco flake can be packed and molded through one-time compaction, so that the height of the whole machine and the stacking height are reduced, the operation is convenient, and the operability and the maintainability of equipment are improved. Meanwhile, the feeding height of the primary pressing material box is reduced, the problem of uneven blanking at high positions is solved, the density of the tobacco leaves is uniform, the requirement that the industry standard DVR is less than or equal to 8 percent is met, and the storage and alcoholization of the tobacco packets at the later stage are facilitated.
