Description

Technical Field

[0001] The utility model relates to the technical field of cigarette manufacturing, in particular to a tobacco leaf kneading device. Background Art

[0002] To facilitate the storage and transportation of tobacco leaves, they are often compacted to reduce their volume, thereby maximizing the storage capacity of tobacco leaves in a limited space. In addition, compaction helps to adjust the moisture content of tobacco leaves. Compacted tobacco leaves are less susceptible to moisture, mold or insects, thereby improving the stability of tobacco leaves during long-term storage, which has a beneficial effect on the subsequent silk making and cigarette production processes.

[0003] In view of the low efficiency of the traditional manual rolling method and the difficulty in ensuring the uniformity and ideal moisture control level of manually rolled tobacco leaves, some patents have disclosed highly mechanized and highly automated tobacco pressing devices to meet the high-standard storage and transportation requirements of tobacco leaves. Such equipment can compact a large amount of tobacco leaves efficiently and evenly, greatly improving the quality and efficiency of the compaction operation.

[0004] For example, the invention patent with the announcement number CN101785575A discloses a method for compacting tobacco leaves and a tobacco leaf compactor, which include: a tobacco leaf conveyor belt, a bracket, a tobacco leaf compacting box, a bottom plate, a tobacco leaf compacting plate, a tobacco leaf compacting plate hydraulic lifting piston, and a tobacco leaf compacting box hydraulic lifting piston, wherein when the tobacco leaf compacting box is filled with tobacco leaves of a pre-weighed standard weight, the tobacco leaf compacting plate hydraulic lifting piston pushes the tobacco leaf compacting plate to move downward along the inner wall of the tobacco leaf compacting box to compact the tobacco leaves, and when the pre-set compacting force is reached, the compacting force is maintained; after the tobacco leaf compacting box hydraulic lifting piston lifts the tobacco leaf compacting box, the tobacco leaf compacting plate hydraulic lifting piston drives the tobacco leaf compacting plate to move upward to separate from the compacted tobacco leaves; the tobacco leaf compacting box hydraulic lifting piston is used to drive the tobacco leaf compacting box to move upward to separate from the tobacco leaf compacting plate after the tobacco leaf compacting plate hydraulic lifting piston pushes the tobacco leaf compacting plate to be pressed down and is in a holding state.

[0005] However, such a device still has its limitations. The above tobacco pressing device realizes the tobacco leaf compacting operation by moving the tobacco leaf compacting plate downward and the tobacco leaf compacting box upward at the same time. However, such one-time over-compacting not only fails to ensure the compactness of the compression, but also easily leads to uneven pressure inside the tobacco leaf, thus affecting the quality of the tobacco leaf.

[0029] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] The utility model provides a tobacco leaf kneading device, such as Figure 1 and Figure 2 As shown, it includes a kneading part 1, a power part 2 and a receiving part 3 for receiving tobacco leaves; the power part 2 drives the kneading part 1 to reciprocate in the vertical direction to repeatedly knead the tobacco leaves in the receiving part 3. The power part 2 is preferably a servo motor. When in use, the power part 2 drives the kneading part 1 to knead the tobacco leaves in the receiving part 3 for multiple times, which helps to apply pressure on the tobacco leaves more evenly, avoids the problem of uneven internal pressure caused by one-time excessive compaction, ensures that the tobacco leaves can be subjected to consistent pressure in the entire receiving part 3, thereby improving the compactness and uniformity of the tobacco leaf compression.

[0031] In some embodiments, in order to realize the continuous automatic operation of tobacco leaf kneading and improve the work efficiency, the tobacco leaf kneading device also includes a conveying part 4 for conveying the accommodating part 3, and the conveying part 4 includes a conveying member 41, and the kneading part 1 is arranged at the end of the conveying member 41; the accommodating part 3 moves toward the kneading part 1 along the conveying member 41. In a specific embodiment, the conveying member 41 is preferably a screw, and the accommodating part 3 is provided with a screw nut, and the screw nut is threadedly connected with the screw. When in use, Figure 1 and Figure 2 As shown, the screw rotates, driving the screw nut threadably matched therewith to perform linear motion along the axis direction of the screw, thereby driving the accommodating portion 3 to move along the length direction of the screw to below the kneading portion 1 to perform tobacco leaf kneading operations.

[0032] As a further improvement of the above embodiment, the conveying part 4 further includes a guide member 42, which is parallel to the conveying member 41 and is slidably connected to the receiving part 3. The guide member 42 can provide precise guidance for the receiving part 3, so that it always maintains a linear motion trajectory when moving along the conveying member 41, avoiding deviation or swinging during the transmission process, thereby ensuring that the tobacco leaves are accurately positioned when being sent to the kneading part 1. In a specific embodiment, the guide member 42 includes two parallel guide rails, and the two ends of the receiving part 3 are respectively slidably connected to the two guide rails.

[0033] In some embodiments, the tobacco leaf kneading device further includes a support portion 5, which includes a support member 51 for supporting the accommodating portion 3 during kneading, and the support member 51 corresponds to the position of the kneading portion 1. The support portion 5 can provide strong and stable support for the accommodating portion 3 so that it does not shake during the compaction process. In addition, the corresponding arrangement of the support member 51 and the kneading portion 1 helps to form a synchronous clamping effect up and down during the kneading process, improve the compaction density and uniformity of the tobacco leaves, and make the tobacco leaves reach an ideal compact state after kneading.

[0034] As a further improvement of the above embodiment, the support part 5 also includes a lifting member 52 for driving the support member 51 to reciprocate in the vertical direction.

In a specific embodiment, the lifting member 52 is a screw elevator, which includes a screw 53 and a driving block 54 for driving the screw 53 to rise and fall. When in use, the driving block 54 drives the screw 53 to rise and fall to drive the lifting and movement of the support member 51. Compared with a hydraulic lift or a pneumatic lift, the screw lift has a relatively simple structure and is easy to maintain. Moreover, when the screw 53 stops rising and falling, no additional energy consumption is required to maintain the position, and the long-term use cost is low.

[0035] In some embodiments, the kneading part 1 includes a circular tobacco kneading disk, whose arc-shaped edge can transition pressure more smoothly than a square one, which helps to reduce stress concentration points, thereby providing a more uniform compaction effect. As a further improvement of this embodiment, the accommodating part 3 is a cylindrical accommodating cavity with an unclosed top surface, and the tobacco kneading disk and the accommodating part 3 have the same diameter.
