The process flow and related equipment have been used in domestic redrying plants for more than thirty years. In the process of use for more than thirty years, each redrying plant has also summarized many problems that need to be improved according to actual needs. For example, due to the density difference in the pre-pressing process, uneven control of moisture and temperature, it may cause quality problems such as hardening of tobacco blocks, internal blackening of tobacco blocks and mold of tobacco blocks during storage and aging of tobacco blocks in the warehouse. For another example, the traditional hydraulic pre-pressing machine and re-pressing machine may sometimes have oil seepage or even oil leakage problems during long-term use, which may cause pollution of tobacco blocks.

[0003] In order to solve the quality problems such as hardening, blackening and mold during storage and aging of tobacco blocks in the warehouse, some manufacturers have added a slicing process on the primary processing line. However, the process is relatively complex, and it is difficult to avoid the consequence of secondary crushing of tobacco caused by slicing machine when slicing the formed tobacco. SUMMARY

DETAILED DESCRIPTION

[0042] Example 1: Application of the box overturning and discharging part group 5 in the tobacco block packaging production line

[0043] According to Figure 5 As shown in the figure, in a specific embodiment, the specific operation process of the box overturning and discharging part group 5 in the tobacco block packaging production line demonstrates that through the cooperation of the box overturning pushing cylinder 15, the box overturning mechanism, the support and hinge device, and the guide device 25, the stable overturning and uniform distribution of the tobacco block are realized, thereby improving the quality of tobacco aging. Through the box overturning and discharging part group 5 in this embodiment, the production line can realize efficient and stable overturning and uniform distribution of the tobacco block, ensuring that the position and distribution of each layer of tobacco block in the layered box are uniform, thereby significantly improving the overall effect of tobacco aging. The precise cooperation of the box overturning pushing cylinder 15, the box overturning mechanism, the guide device 25, and the support and hinge device makes the overturning action stable and efficient on the entire production line, further improving the quality and production efficiency of the tobacco block packaging.

[0044] The structure of the box turning and discharging unit group 5: the box turning and pushing cylinder 15 is the core driving component of the box turning and discharging unit group 5, usually in the shape of a long cylinder, controlled by a hydraulic or pneumatic system; the box turning and pushing cylinder 15 is installed obliquely on one side of the box turning mechanism, connected to the box turning mechanism through the piston rod, providing the turning power. The box turning mechanism is a square or rectangular metal box structure, installed in front of the box turning and pushing cylinder 15; the box turning mechanism is connected to the frame group 11 through hinges or rotating shafts, and can tilt or turn under the action of the pushing cylinder, used to redistribute the tobacco blocks into the layered boxes. The support and hinge device is installed on the side or bottom of the box turning mechanism, providing support and turning fulcrum for the box turning mechanism. The device is made of high-strength metal materials to ensure stability and accuracy during turning. The guide device 25 is installed on both sides or the bottom of the box turning mechanism to ensure smooth movement along the predetermined trajectory during turning, preventing deviation or instability during turning.

[0045] The box turning and discharging unit group 5 is closely connected with the pushing unit group 3, receiving the pre-pressed tobacco blocks pushed by the pushing unit group 3. After the pushing unit group 3 completes the pushing, the tobacco blocks enter the box turning mechanism of the box turning and discharging unit group 5, preparing for turning and redistribution. The box turning and discharging unit group 5 evenly distributes the turned tobacco blocks in the layered boxes, and the layered box lifting group 4 adjusts the position and level of the layered inner box 20 to ensure uniform distribution of tobacco blocks in each layer.

[0046] The turning operation process of the box turning and discharging unit group 5 is as follows:

[0047] S1. Tobacco block receiving and turning start: when the pushing unit group 3 pushes the pre-pressed tobacco blocks into the box turning mechanism of the box turning and discharging unit group 5, the electrical control system sends a signal to start the box turning and pushing cylinder 15; the box turning and pushing cylinder 15 pushes the box turning mechanism through the piston rod, starting the turning operation of the tobacco blocks; the stroke and force of the box turning and pushing cylinder 15 are accurately controlled by the electrical control system according to the process requirements, ensuring the smooth operation of the box turning.

[0048] S2. Turning of the box turning mechanism and distribution of the tobacco blocks: the box turning mechanism turns along the rotating shaft of the support and hinge device under the pushing of the box turning and pushing cylinder 15. At this time, the tobacco blocks in the box body are tilted or turned, gradually distributed to each area of the layered box. During the turning process, the tobacco blocks are evenly distributed at the bottom or corners of the layered box due to the action of gravity and the movement of the box body. This uniform distribution helps to improve the quality of the tobacco blocks during the aging process, ensuring the uniformity of the aging effect.

[0049] S3. Guiding effect of the guiding device 25: During the turning process of the turning mechanism, the guiding device 25 ensures that the movement trajectory of the turning mechanism remains stable. The guiding device is usually composed of sliding rails or guiding rods, installed on both sides or the bottom of the turning mechanism, and fixedly connected with the rack part 11, preventing deviation or tilting during the turning process. The guiding device 25 ensures the smooth operation of the turning action, preventing uneven distribution of tobacco blocks due to unstable movement of the turning mechanism.

[0050] S4. Turning completion and resetting: After the turning action is completed, the tobacco blocks have been evenly distributed in the layered boxes. At this time, the electrical control system sends a stop signal, the piston rod of the turning push cylinder 15 is retracted, and the turning mechanism returns to the initial position, preparing for the next tobacco block turning process. During the resetting process, the turning mechanism still moves smoothly under the guidance of the guiding device 25, ensuring the continuity and stability of the overall operation of the equipment.

[0051] Throughout the tobacco block packaging production line, the precise operation of the turning and discharging part group 5 is crucial for maintaining uniform distribution of tobacco blocks and improving the aging effect. Through the smooth turning of the turning and discharging part group 5, tobacco blocks can be evenly distributed in the layered boxes, providing a stable raw material basis for subsequent aging and packaging operations. The turning and discharging part group 5 closely cooperates with the pushing part group 3 and the layered box lifting part group 4, ensuring smooth transition between each link of the entire production process, and ultimately ensuring the quality and efficiency of tobacco block aging and packaging.

[0052] All actions of the turning and discharging part group 5 are managed by the electrical control system. The electrical control system accurately controls the start and stop of the turning push cylinder 15 according to the working state of the pushing part group 3 and the layered box lifting part group 4, ensuring that the turning action is synchronized with the overall rhythm of the production line. The electrical control system monitors the progress of the turning action in real time, such as the position signal of the turning mechanism, the turning angle, and the distribution of tobacco blocks, to ensure the accuracy and reliability of each action.

[0066] The box turning and pushing cylinder 15 is connected to the layered box turning mechanism through the piston rod, and the support device fixes the cylinder body below the layered box lifting part group 4. The hydraulic control system or pneumatic control system is connected to the box turning and pushing cylinder 15 through hydraulic pipes or gas pipes, and the hydraulic control system or pneumatic control system is adjusted to ensure accurate and smooth box turning during production.

[0067] The operation process of the box turning and pushing cylinder 15 is as follows:

[0068] S1. Start the box turning action: when the tobacco block is formed by the pre-pressing machine group 2, the hydraulic control system or pneumatic control system sends a signal to start the box turning and pushing cylinder 15. The piston of the box turning and pushing cylinder 15 starts to move forward under the action of the hydraulic or pneumatic system, pushing the piston rod to drive the layered box to turn over.

[0069] S2. Turning process: as the piston rod advances, the layered box slowly and smoothly turns from a horizontal position to a vertical position; the tobacco block remains stable during the turning process in the layered box, ensuring that the tobacco block can be vertically inserted into the carton 24, reducing the displacement or damage of the tobacco block during the turning process.

[0070] S3. Reset and preparation after turning over: After the layered box completes the turning over action, the piston rod of the turning box pushing cylinder 15 is gradually withdrawn to the initial position through the control of the hydraulic control system or the pneumatic control system. The layered box is also gradually restored to the horizontal position under the driving of the turning box pushing cylinder 15, preparing to welcome the next batch of tobacco block turning operation.

[0071] In a complete tobacco block packaging production line, the hydraulic control system or the pneumatic control system is connected with the turning box pushing cylinder 15 through hydraulic pipes or air pipes to control the action of the turning box pushing cylinder 15 in real time. The hydraulic control system or the pneumatic control system can flexibly adjust the stroke and speed of the piston rod according to the specifications and turning requirements of the tobacco blocks, ensuring the accuracy of each turning action. The turning box pushing cylinder 15 is connected with the layered box lifting group 4 through the piston rod to push the layered box to turn over. The layered box lifting group 4 provides the necessary structural support to ensure that the layered box does not shift or tilt during the turning process. The turning box pushing cylinder 15 is fixed below the layered box lifting group 4 through the support device, which ensures that the turning box pushing cylinder 15 remains stable during work and does not move or vibrate due to external forces or changes in thrust.

[0072] Example 3: Application of lifting group 19 in tobacco block packaging production line

[0073] In a specific embodiment, the lifting group 19 realizes precise lifting and positioning operation of the layered box sleeve 16 and the layered inner box 20 in the tobacco block packaging production line.

Through automatic lifting and control operation, the lifting group 19 significantly improves the overall efficiency of the production line, ensuring the quality of the tobacco blocks and the continuity of the production.

[0074] The structure of the lifting group 19: the electric cylinder of the lifting group 19 is a cylindrical structure made of high-strength aluminum alloy and installed on the side of the equipment frame; the electric cylinder converts the rotary motion of the motor into linear motion through the internal screw rod and nut mechanism to drive the support plate to move the layered box cover 16 and the layered inner box 20 up and down; the length and thrust of the electric cylinder are designed according to the weight and lifting height of the layered box to ensure stable lifting operation. The support plate is a steel flat plate structure installed at the bottom of the layered box cover 16; the support plate is connected with the screw rod of the electric cylinder to transmit the thrust of the electric cylinder to the layered box cover 16 and the layered inner box 20; the support plate has sufficient rigidity and strength to withstand the weight of the layered box and the tobacco bricks / tobacco blocks and ensure the stability of the lifting process. The guide device 25 is a high-strength metal slide rail installed on both sides of the layered box cover 16 and cooperates with the guide system of the lifting group 19; the guide device 25 ensures that the layered box maintains linear motion during lifting and lowering to avoid jamming or damage caused by deviation or inclination and ensures the accuracy of the lifting action. The motor of the lifting group 19 is a servo motor installed at one end of the electric cylinder and transmits rotary motion to the screw rod through a reducer to control the up and down movement of the layered box.

[0075] The layered lifting and positioning operation of the lifting group 19 runs as follows:

[0076] S1. Pre-pressing operation of tobacco bricks / tobacco blocks: when the layered box cover 16 and the layered inner box 20 are in the initial position, the electric cylinder of the lifting group 19 is in the retracted state, and the layered box cover 16 and the layered inner box 20 are located at the lower end, waiting for the filling and pre-pressing operation of the tobacco blocks; at this time, the guide device ensures that the layered box cover 16 is in a horizontal state to provide a good foundation for the uniform distribution and compaction of the tobacco blocks.

[0077] S2. Layered operation of tobacco bricks / tobacco blocks: as the production proceeds, the tobacco blocks are filled layer by layer into different layer compartments of the layered inner box 20; when a layer compartment is filled, the control system starts the lifting group 19, the electric cylinder begins to extend, and the support plate drives the layered box cover 16 and the layered inner box 20 to gradually rise until reaching the next specified height; at this time, the guide device 25 ensures that the lifting process of the layered box is stable and has no inclination.

[0078] S3. Precise lifting and positioning: According to the set process requirements, the control system precisely controls the extension and retraction of the electric cylinder through sensor feedback, ensuring that the inner box 20 in each lifted layer is at the correct height, ready to receive new tobacco blocks; the control system automatically adjusts the speed and thrust of the electric cylinder to adapt to different batches and weights of tobacco blocks, ensuring uniform distribution of tobacco leaves in each layer.

[0079] S4. Locking and stabilizing: After the layered box sleeve 16 and the inner box 20 reach the set height, the electric cylinder of the lifting group 19 stops moving, and the layered box sleeve 16 remains at that height, waiting for the filling of tobacco blocks; at this time, the fixed support and guide device play a stabilizing and locking role, preventing the layered box from shifting or shaking during the filling process.

[0080] S5. Continue layering: After the filling of each tobacco brick / tobacco block is completed, the lifting group 19 continues to follow the predetermined program to gradually lift the layered box sleeve 16 and the inner box 20 to the next designated height until all layers are filled with tobacco blocks; each lifting and positioning process is automatically controlled by the control system, ensuring the efficiency and accuracy of the entire production process.

[0081] S6. End operation: When all layers of the layered box are filled, the electric cylinder of the lifting group 19 lowers the layered box sleeve 16 and the inner box 20 to the initial position, preparing for the overturning or transfer operation; the fixed support and guide device 25 continue to provide support during the lowering process, ensuring stable operation of the entire equipment.

[0082] In a complete tobacco block packaging production line, the lifting group 19 closely cooperates with the layered box sleeve 16 to accurately lift the layered box sleeve 16 and the inner box 20 to the set height through the drive of the electric cylinder and the supporting plate; the guide device 25 ensures that the layered box does not tilt during lifting, ensuring uniform distribution of tobacco blocks in the inner box 20. The linkage operation of the lifting group 19 and the control system, through real-time monitoring and sensor feedback, precisely controls the stroke and speed of the lifting action, ensuring the accuracy of each lifting and avoiding misoperation or misplacement of tobacco blocks during production. The fixed support and guide device 25 provide strong support and stable guidance for the lifting group 19, ensuring that the electric cylinder remains stable during lifting and lowering, avoiding equipment failure or production delay due to shaking or deviation.

[0097] The operation process of the layered inner box 20 is as follows:

[0098] S1. Tobacco brick / block loading: through the feeding device, the tobacco bricks / blocks enter the layered inner box 20 in sequence, and the layered separation device stacks the tobacco bricks / blocks by layer; after each layer of tobacco bricks / blocks is stacked, the lifting group 19 drives the layered inner box 20 to move downward, preparing for the loading of the next layer.

[0099] S2. Layer adjustment: according to the thickness and size of the tobacco bricks / blocks, the position of the partition plate is adjusted to ensure that the stacking height of each layer of tobacco bricks / blocks is consistent, preventing uneven stacking during subsequent compression and turning.

[0100] S3. Compression operation: after the tobacco bricks / blocks are completely loaded, the layered inner box 20 is fine-tuned under the drive of the lifting group 19 to ensure uniform stress on the tobacco bricks / blocks; if necessary, the layered inner box 20 cooperates with the pressure head group for pre-compression to ensure that each layer of tobacco bricks / blocks is tightly stacked, facilitating subsequent processing.

[0105] The inventors of the present application have conducted extensive research and testing on the layered pre-pressing and packaging all-in-one machine for improving the quality of tobacco aging. The main research and testing is in the following two aspects:

[0106] First, verify that the change from one-time forming and single-block packaging to small single-quantity multiple-forming and multi-block combined packaging substantially improves the quality of tobacco aging. The inventors have conducted extensive simulation production testing and comparative testing using existing equipment. The specific test data is shown in Table 1 (change range of xibasane degradation product content).

[0107] Table 1: Test results of change range of xibasane degradation product content

[0108]

[0109] As shown in Table 1, from the change range of xibasane degradation product content, it can be seen that at 6 months of aging time, the change range of the layered and compartmented samples is significantly greater than that of the control sample except for the horizontal four-layer sample, indicating that the aging reaction of the layered and compartmented samples is more intense than that of the control sample during the 0-6 month aging period. At 10 months of aging time, the change range of the layered and compartmented samples is significantly greater than that of the control sample except for the horizontal four-layer sample, indicating that the aging reaction of the layered and compartmented samples is more intense than that of the control sample during the 10-month aging period. It can be seen that after the tobacco is packaged in layers and compartments, it is beneficial to improve the aging quality and rate of the tobacco.

[0110] Second, the problem of keeping production efficiency unchanged and reducing equipment cost. Specifically, if the layered packaging technology only changes the original one-time molding and single block packaging form to small single quantity and multiple molding and multiple block combined packaging form, but if the original production method is followed and only small modifications are made, the production efficiency will easily decrease significantly. Therefore, it is necessary to improve the layered packaging technology as a whole.

[0111] The basic concept of the layered pre-press packaging all-in-one machine described in the application includes: using a set of equipment to replace the functions of the original pre-press machine, re-press machine and slicing machine in the workshop, optimizing and adjusting the production process of the original imported equipment, and avoiding the crushing consequences caused by the slicing machine when cutting the already molded tobacco leaves.
