[0041] Example 1: Application of layered box lifting part group 4 in tobacco block packaging production line

[0042] According to Figure 6 As shown in the figure, the layered box lifting part group 4 is a key component in the layered pre-pressing and packaging all-in-one machine for improving the quality of tobacco aging, and the main function is to realize the uniform distribution and storage of tobacco bricks / tobacco blocks in different box grids by lifting and lowering different levels in the layered box.

[0043] In a specific embodiment, the specific operation process of the layered box lifting part group 4 in the tobacco brick / tobacco block packaging production line demonstrates that through the cooperation of the layered inner box 20, the layered box sleeve 16, the material blocking plate 17, the material blocking plate opening and closing cylinder 18, and the lifting part group 19, the accurate distribution and processing of tobacco bricks / tobacco blocks in different levels are realized, thereby improving the quality of tobacco block aging. Through the layered box lifting part group 4 in this embodiment, the production line can realize the efficient and stable distribution of tobacco bricks / tobacco blocks in the layered inner box 20, ensuring the uniformity of each layer of tobacco bricks / tobacco blocks in the aging process. The accurate cooperation of the layered inner box 20, the layered box sleeve 16, the material blocking plate 17, the material blocking plate opening and closing cylinder 18, and the lifting part group 19 enables the uniform distribution and efficient processing of tobacco bricks / tobacco blocks on the entire production line, further improving the overall quality and production efficiency of tobacco block packaging.

[0044] The structure of the layered box lifting group 4 is configured as follows: the layered box sleeve 16 is a rectangular or square shell that wraps around the layered inner box 20, serving as a support and protection; the layered box sleeve 16 is installed on the lifting group 19's supporting plate and moves up and down through the lifting group 19. The layered inner box 20 is a container that carries tobacco bricks / blocks, with multiple layers inside for storing different levels of tobacco blocks; the layered inner box 20 is installed inside the layered box sleeve 16 and moves up and down with the layered box sleeve 16, ensuring that the tobacco blocks are evenly distributed in different levels. The material blocking plate 17 is a flat plate structure installed on the side or bottom of the layered box sleeve 16 and connected by a hinge, allowing it to open and close to control the distribution of tobacco bricks / blocks. The material blocking plate 17 controls the falling of tobacco bricks / blocks, ensuring that each layer of tobacco blocks is evenly distributed as needed. The material blocking plate opening and closing cylinder 18 is a cylindrical cylinder installed on the side of the layered box sleeve 16 to control the opening and closing of the material blocking plate 17, achieving precise control of the tobacco blocks. The lifting group 19 is an electric cylinder or hydraulic cylinder installed at the bottom or side of the equipment, driving the layered box sleeve 16 and the layered inner box 20 to move up and down, ensuring the even distribution and storage of tobacco blocks in different levels.

[0045] The layered box lifting group 4 closely cooperates with the box flipping and unloading group 4 to receive the flipped tobacco bricks / blocks. The lifting group 19 adjusts the height of the layered inner box 20 to ensure that the tobacco bricks / blocks are evenly distributed in the different layers of the layered inner box 20 in sequence.

[0046] The layered box lifting group 4 operates as follows:

[0047] S1. Tobacco block receiving and height adjustment: When the box flipping and unloading group delivers the flipped tobacco bricks / blocks to the layered box lifting group 4, the electrical control system instructs the lifting group 19 to adjust the height of the layered inner box 20. The lifting group 19 drives the layered box sleeve 16 and the layered inner box 20 inside it to move up and down through the electric cylinder or hydraulic cylinder, aligning the top of the layered inner box 20 with the inlet of the tobacco bricks / blocks. The layered box sleeve 16 protects the layered inner box 20 while ensuring its stability and smooth lifting movement.

[0048] S2. Material blocking plate 17 opening and closing and tobacco block distribution: As the layered inner box 20 reaches the specified height, the electrical control system instructs the material blocking plate opening and closing cylinder 18 to start and control the opening and closing of the material blocking plate 17. The material blocking plate 17 opens at the right time to allow the tobacco bricks / blocks to fall into the different layers of the layered inner box 20 in sequence. During the tobacco brick / block falling process, the opening and closing action of the material blocking plate 17 is precisely controlled by the electrical control system to ensure that the tobacco bricks / blocks are evenly distributed in each level, avoiding accumulation or deviation in the layered inner box 20.

[0049] S3. Layer-by-layer distribution and storage: Each layer of the layered inner box 20 will receive the tobacco bricks / tobacco blocks in turn, and the electrical control system will adjust the height of the layered inner box 20 layer by layer according to the production requirements. When a layer of tobacco blocks is full, the lifting group 19 will lower the layered inner box 20 to the next layer position, and the baffle plate 17 will open again to allow the tobacco bricks / tobacco blocks to enter the new layer. Layer-by-layer processing ensures uniform distribution of each layer of tobacco blocks, optimizing the effect of the tobacco blocks during the aging process.

[0050] S4. Layering completion and preparation for the next processing cycle: When all layers of tobacco bricks / tobacco blocks have been stored according to the set requirements, the lifting group 19 will adjust the layered inner box 20 to the initial position, preparing to receive the next batch of tobacco bricks / tobacco blocks. The baffle plate 17 is closed to ensure stable storage of the tobacco bricks / tobacco blocks in the layered inner box 20. After uniform distribution of the tobacco bricks / tobacco blocks in the layered inner box 20, subsequent aging treatment can be carried out to ensure consistent aging effect of each layer of tobacco bricks / tobacco blocks.

[0051] In the entire tobacco block packaging production line, the close cooperation between the layered box lifting group 4 and the box turning and discharging group 4 and other groups ensures smooth transition between each link of the entire tobacco block packaging production line. Through precise operation of the layered box lifting group 4, the tobacco block packaging production line can ensure uniform distribution and stable storage of the tobacco blocks, ultimately improving the aging effect and production efficiency. All operations of the layered box lifting group 4 are managed by the electrical control system. The tobacco block packaging production line accurately controls the actions of the lifting group 19 and the baffle plate opening and closing cylinder 18 according to production requirements, ensuring that the lifting position of the layered inner box 20 and the opening and closing state of the baffle plate 17 are consistent with the production rhythm. The electrical control system of the tobacco block packaging production line can monitor the progress of the layering process in real time, adjust the lifting speed of the lifting group 19 and the opening and closing time of the baffle plate 17, and ensure that each layer of tobacco bricks / tobacco blocks can be accurately distributed in the corresponding layer.

[0128] The inventor of the present application has conducted a long-term research and test on the layered pre-pressing and packaging all-in-one machine for improving the quality of tobacco aging, mainly in the following two aspects:

[0129] Firstly, the change from one-time forming and single block packaging to small single quantity and multiple forming and multiple block combined packaging substantially improves the quality of tobacco aging. The inventor has conducted a long-term simulation production test and comparative detection using existing equipment. The specific detection data is shown in Table 1 (detection results of content change range of cembrane degradation products).

[0130] Table 1 is the detection results of content change range of cembrane degradation products

[0131]

[0132] As shown in Table 1, from the content variation range of cedrane degradation products, it can be seen that when the alcoholization time is 6 months, the variation range of the rest of the layered and gridded samples is obviously greater than that of the control sample except for the horizontal four-layer sample, which indicates that the alcoholization reaction of the layered and gridded samples is more intense than that of the control sample during the 0-6 month alcoholization period. When the alcoholization time is 10 months, the variation range of the rest of the layered and gridded samples is obviously greater than that of the control sample except for the horizontal four-layer sample, which indicates that the alcoholization reaction of the layered and gridded samples is more intense than that of the control sample during the 10-month alcoholization period. It can be seen that after the tobacco leaves are packaged in layers and grids, the alcoholization quality and alcoholization rate of the tobacco leaves are improved.

[0133] Second, the problem of keeping production efficiency unchanged and reducing equipment cost, specifically, if the layered packaging technology only changes the original one-time forming, single block packaging form into small single quantity multiple forming, multi-block combined packaging form, but if the original production method is followed, only small modifications are made, the production efficiency is easy to be greatly reduced. Therefore, it is necessary to improve the layered packaging technology as a whole.

[0134] The basic concept of the layered pre-pressing packaging all-in-one machine includes: using a set of equipment to replace the functions of the original workshop pre-pressing machine, re-pressing machine and slicing machine, optimizing and adjusting the production process of the original imported equipment, and avoiding the crushing of tobacco leaves caused by the slicing machine when cutting the formed tobacco leaves.
