Description

Technical Field

[0001] The present invention is applied to a tobacco leaf redrying workshop in the tobacco industry, and relates to the technical field of tobacco leaf forming and packaging processing equipment. It is mainly used in the production process of pre-pressing qualified tobacco sheets into several tobacco blocks / sheets after redrying, then storing the pressed tobacco blocks / sheets in layers, and finally loading the whole into a cigarette box. Background Art

[0002] In the current tobacco redrying workshop in the tobacco industry, the production process and related equipment (traditional hydraulic pre-pressing machine and re-pressing machine) of pre-pressing qualified tobacco leaves into blocks in the tobacco box after redrying, and then re-weighing, re-pressing, packaging, bundling and storage are imitated from the foreign Feisi Company. This set of process flow and related equipment have been used in domestic redrying plants for more than 30 years. During the more than 30 years of use, various redrying plants have also summarized many problems that need to be improved according to actual needs. For example: due to the density difference, uneven moisture and temperature control during the pre-pressing process, tobacco leaves may have quality problems such as tobacco block hardening, internal burning and blackening of tobacco blocks, and tobacco block mildew during storage and aging in the warehouse. For another example: traditional hydraulic pre-pressing machines and re-pressing machines sometimes have oil seepage or even oil leakage during long-term use, resulting in contamination of tobacco blocks and tobacco leaves.

[0003] To solve these problems, various manufacturers have also made various attempts. For example, in order to solve the quality problems of tobacco leaves such as compaction, burning, blackening and mildew during storage and aging in warehouses, some manufacturers have added a slicing process to the silk production line. However, the process is relatively complicated, and it is difficult to avoid the consequences of the tobacco leaves being broken when the slicer cuts the formed tobacco leaves.

[0004] In general, the current pre-pressing and baling methods at home and abroad are not perfect, regardless of whether the slicing process is used in the production of silk thread. The relevant technical solutions of similar patents are as follows:

[0005] The Chinese invention (CN102642635A) discloses a layered and gridded pre-pressing machine for tobacco leaf packaging, including: The present invention relates to a new type of pre-pressing machine for layered and gridded tobacco leaves, which is mainly used in tobacco leaf threshing and redrying enterprises in the tobacco industry to perform layered and gridded pre-pressing and packing when qualified loose tobacco leaves are loaded into cigarette packs in the tobacco leaf redrying workshop, and then the boxes are sealed and packaged. It mainly consists of: a pre-pressing machine frame (1), a main pre-pressing cylinder (4), a pre-pressing head (5) and a convex tooth pressure block (10), a movable sleeve box (6), a sleeve box lifting cylinder (11), etc. The pre-pressing machine adopts a special sleeve box and a hydraulically driven special pre-pressing head to form a working mechanism for layered and gridded pre-pressing of loose materials (tobacco leaves); the pre-pressing machine adopts a working mode of multiple quantitative feeding and multiple pre-pressing, so that the pre-pressed tobacco leaves form a number of obvious tobacco leaf layer distributions in the cigarette box. This tobacco leaf layering has both vertical and horizontal stratification. However, the tobacco leaf pre-pressing packaging machine mentioned in the invention is an invention patent applied for in 2012. The pre-pressing parts of the patent are all driven by hydraulic cylinders; there is no pushing part, layered box lifting part, box turning and unloading part, unloading push rod part, etc. The characteristic of this patent is that the unloading, pre-pressing and pressure-maintaining steps of tobacco leaves are carried out multiple times in one packaging carton. The advantage of this operation is that it does not change much from traditional equipment and has a simple structure; the disadvantage is that the density of each pre-pressed tobacco block is not uniform. The tobacco blocks at the bottom are pressed more times and have a relatively high density, while the tobacco blocks at the top are pressed less times and have a relatively low density.

[0006] The Chinese utility model (CN202717056U) discloses a layered and gridded pre-pressing machine for tobacco leaf packaging, including: The utility model relates to a layered and gridded pre-pressing machine for tobacco leaf packaging, which is mainly used for tobacco leaf threshing and redrying enterprises in the tobacco industry to carry out layered and gridded pre-pressing and packing when qualified loose tobacco leaves are loaded into cigarette packs in the tobacco leaf redrying workshop, and then the boxes are sealed and packaged. It mainly consists of: a pre-pressing machine frame (1), a main pre-pressing cylinder (4), a pre-pressing head (5) and a convex tooth pressure block (10), a movable sleeve box (6), a sleeve box lifting cylinder (11), etc. The pre-pressing machine adopts a special sleeve box and a hydraulically driven special pre-pressing head to form a working mechanism for layered and gridded pre-pressing of loose materials (tobacco leaves); the pre-pressing machine adopts a working mode of multiple quantitative feeding and multiple pre-pressing, so that the pre-pressed tobacco leaves form a number of obvious tobacco leaf layer distributions in the cigarette box. This tobacco leaf layering has both vertical layering and horizontal layering. The layered distribution of tobacco leaves is beneficial to the aging of tobacco leaves in the storage warehouse, which can not only improve the quality of tobacco leaves, but also shorten the aging cycle. However, this utility model patent has the same disadvantages as the aforementioned patent CN102642635A: the pre-pressing group of this patent is driven by a hydraulic cylinder; there is no pushing group, layered box lifting group, box turning and unloading group, unloading push rod group, etc. This patent also performs the unloading, pre-pressing and pressure-maintaining steps of tobacco leaves multiple times in a packaging carton. Therefore, there is also a problem that the density of each pre-pressed cigarette block is not uniform, the cigarette block located at the bottom is pressed more times and has a relatively high density, while the cigarette block located at the top is pressed less times and has a relatively low density. Moreover, although this operation improves the quality, the efficiency is significantly reduced compared to the traditional pre-pressing packaging technology.

[0007] The Chinese invention (CN105966695A) discloses a tobacco leaf slicing and pre-pressing packaging machine for packaging tobacco leaves after redrying, comprising: The present invention discloses a tobacco leaf slicing and pre-pressing packaging machine for packaging tobacco leaves after redrying, aiming to provide a tobacco leaf slicing and pre-pressing packaging machine for packaging tobacco leaves after redrying with high reliability. It includes a shaping device, and a pre-pressing and forming device, a pressure-holding device and a packing device arranged in sequence; the pre-pressing and forming device includes a pre-pressing and forming frame, a pre-pressing and forming oil cylinder vertically arranged on the pre-pressing and forming frame, a pre-pressing head installed at the end of the piston rod of the pre-pressing and forming oil cylinder, a sleeve box installed on the pre-pressing and forming frame through a two-piece sleeve box lifting cylinder, a workbench fixedly arranged on the pre-pressing and forming frame, and a push-out mechanism fixedly arranged on the pre-pressing and forming frame; the pressure-holding device includes a pressure-holding frame, a rectangular pressure-holding tube rotatably installed on the pressure-holding frame, located on the opposite side of the push-out mechanism and open on the side, a pressure-holding mechanism arranged at the lower end of the rectangular pressure-holding tube, and a pushing mechanism arranged on the rectangular pressure-holding tube opposite to its open end. However, the invention integrates multiple functions to improve the packaging efficiency of tobacco leaves after processing. The goal of this invention is to provide a structurally reliable system that realizes the pre-pressing and packaging of tobacco leaves through a shaping device, a pre-pressing and forming device, a pressure-holding device and a packing device. The pre-pressing part of the invention patent is driven by a hydraulic cylinder; the material pushing part is also a small batch multiple forming and multi-piece combined packaging form. However, the structure of the invention patent is relatively complex and has many process steps, which not only affects the production efficiency but also easily increases the failure rate of the equipment.

[0008] The Chinese invention (CN201620706206.0) discloses a tobacco leaf slicing and pre-pressing packaging machine for packaging tobacco leaves after redrying, comprising: The utility model discloses a tobacco leaf slicing and pre-pressing packaging machine for packaging tobacco leaves after redrying, aiming to provide a tobacco leaf slicing and pre-pressing packaging machine for packaging tobacco leaves after redrying with high reliability. It includes a shaping device, and a pre-pressing and forming device, a pressure-maintaining device and a packing device arranged in sequence; the pre-pressing and forming device includes a pre-pressing and forming frame, a pre-pressing and forming oil cylinder vertically arranged on the pre-pressing and forming frame, a pre-pressing pressure head installed at the end of the piston rod of the pre-pressing and forming oil cylinder, a reciprocating belt conveyor installed on the pre-pressing and forming frame through two reciprocating belt conveyor lifting cylinders, a workbench fixedly arranged on the pre-pressing and forming frame, and a push-out mechanism fixedly arranged on the pre-pressing and forming frame; the pressure-maintaining device includes a pressure-maintaining frame, a rectangular pressure-maintaining tube rotatably installed on the pressure-maintaining frame, located on the opposite side of the push-out mechanism and open on the side, a pressure-maintaining mechanism arranged at the lower end of the rectangular pressure-maintaining tube, and a pushing mechanism arranged on the rectangular pressure-maintaining tube opposite to its open end. This invention is a device designed to solve specific tobacco leaf processing problems, including shaping devices, pre-pressing and forming devices, pressure-maintaining devices and packing devices, and is mainly used for the pre-pressing, pressure-maintaining and packaging processes of tobacco leaves. However, this technology still has some shortcomings when solving some specific problems, mainly including: First, equipment complexity and maintenance requirements. Due to the complex structure of the machine and the involvement of multiple mechanical parts, its maintenance may be difficult and costly. Complex mechanical systems may be prone to failure, increasing downtime and repair costs. Second, operational efficiency. Although the equipment integrates the functions of pre-pressing machine, re-pressing machine and slicer, the operating process steps are relatively cumbersome, which will affect the overall production efficiency.

[0009] The Chinese invention (CN201820919454.2) discloses a layered tobacco finished product baler, including: The utility model relates to a layered tobacco finished product baler, which belongs to the technical field of tobacco processing equipment; the layered tobacco finished product baler includes a primary processing unit, a secondary processing unit, a tertiary processing unit, a pre-pressing machine pressure head, a main pre-pressing cylinder, a cigarette box, and a cigarette box conveyor roller. This invention attempts to improve the efficiency and quality of tobacco leaf processing from another perspective. This machine grades tobacco leaves through multiple processing units before feeding the pre-pressing machine, thereby improving the processing efficiency and the final quality of the tobacco leaves. This is a completely different technical solution from the present invention.

This utility model patent is to add a layered sheet to the traditional pre-pressing machine pressure head, so that the original pre-pressed whole tobacco sheet becomes the current four tobacco sheets, which can realize the process of subtracting the cutting into four tobacco sheets in the silk making, reduce the tobacco leaf crushing, and improve the availability and processing efficiency of the tobacco leaves. Such a solution can indeed eliminate the process of cutting the tobacco into four sheets during the silk making process, but it puts the cutting process in the pre-pressing stage, which will also cause the tobacco leaves to be broken during the pre-pressing process. Summary of the invention

[0038] The working process of the layered pre-pressing and packaging integrated machine for improving the quality of tobacco leaf aging of the present invention is as follows:

[0039] The working process of the integrated baler involves the precise coordination of multiple components to form a continuous operation process to improve the aging quality and packaging efficiency of tobacco leaves. The following are the detailed steps of the working process:

[0040] S1. Unloading: After being roasted in the previous process, the tobacco blocks first enter the tobacco conveyor (7); after being weighed and quantitatively unloaded on the tobacco conveyor (7), the tobacco blocks are evenly dropped onto the reciprocating belt conveyor (9) by the electric roller material distribution unit (8), and the reciprocating belt conveyor (9) then delivers the tobacco blocks to the box of the pre-pressing machine unit (2) for pre-pressing.

[0041] S2. Pre-pressing: After the material is unloaded, the pre-pressing electric cylinder (12) in the pre-pressing machine group (2) pushes the pressing head group (10) downward to compress the tobacco leaves into tobacco blocks of specified specifications and weights; after maintaining the pressure for 3-6 seconds, the pre-pressing electric cylinder (12) drives the pressing head upward to return to its original position, preparing for the next pressing cycle.

[0042] S3. Pushing: While the pressing head of the pre-pressing unit (2) is returning to its original position, the pushing unit (3) pushes the pressed tobacco blocks into the corresponding spaces of the layered inner box (20).

[0043] S4. Layered lifting: The layered box lifting unit (4) operates the lifting unit (19) to drive the layered box sleeve (16) and the layered inner box (20) to move up one layer to prepare for the pre-pressing of the next layer of tobacco blocks.

[0044] S5. Repeat: Repeat steps 1 to 4 until all spaces of the layered inner box (20) are filled.

[0045] S6. Turning over and unloading: The empty packaging carton (24) enters the designated position, and the turning over and pushing cylinder (15) in the turning over and unloading section (5) works to turn over the layered box sleeve (16) and align it with the packaging carton. Then, the baffle plate (17) of the layered box lifting section opens, and the pressing head group (21) of the unloading push rod section (6) moves downward to push the cigarette block into the packaging carton.

[0046] S7. Layered packaging: The pressure head group (21) in the unloading push rod group (6) moves upward, the baffle plate (17) returns to its position, and the loaded packaging carton (24) moves forward to the next station.

[0047] S8. Box turning and returning to position: The box turning and pushing cylinder in the box turning and unloading unit (5) works, pulling the layered box sleeve (16) back to the starting position, preparing for the next round of pushing and packaging.

[0048] In order to improve production efficiency, multiple layered pre-pressing and baling machines can be deployed in parallel, and the effective distribution and continuous input of raw materials can be achieved through conveyors to form an integrated unit production line. The design of the entire process ensures that the processing of tobacco leaves at each stage can meet the established quality standards, while achieving automated and efficient production.

[0049] Compared with the traditional hydraulic pre-pressing machine and re-pressing machine, the layered pre-pressing and baling machine of the present invention has the following advantages:

[0050] 1. By packaging small cigarette blocks / sheets in layers, each small cigarette block in each cigarette stack in a carton (cigarette box) can be naturally and evenly layered, so that each small cigarette block / sheet in the cigarette box can achieve air circulation during storage with the help of the micro-air permeable channels between each cigarette block / sheet layer, thereby more effectively regulating the temperature and moisture of the cigarette block / sheet, avoiding core burning and carbonization, reducing tobacco leaf mildew, promoting tobacco leaf aging, shortening the aging cycle, and improving the quality of tobacco leaf aging.

[0051] 2. A set of equipment was used to replace the functions of the pre-pressing machine, re-pressing machine and slicer in the original workshop, and the production process of the original imported equipment was optimized and adjusted, and the consequences of the slicer cutting the formed tobacco leaves to break the tobacco leaves were avoided.

[0052] 3. The height of the equipment has been effectively reduced, and the height of the pre-pressing machine and baling machine has been reduced from the original 21 meters to about 12 meters. This greatly reduces the design requirements for the factory building and effectively reduces costs.

[0053] 4. After the main compaction mechanism is changed from an oil cylinder to an electric cylinder, the hidden danger of oil leakage in the original traditional pre-pressing baler is avoided.

[0054] 5. After the weight of a single pressed cigarette stack is reduced from the original 200kg / piece to 50kg / piece or even 40kg / piece, it is convenient to produce cigarettes in small batches and meet the customized and personalized cigarette production needs in the current market.

[0055] 6. The weight of a single pressed cigarette stack is reduced from the original 200kg / piece to 50kg / piece or even 40kg / piece, which reduces the pressure on logistics and facilitates the next step of intelligent operation. BRIEF DESCRIPTION OF THE DRAWINGS

Numbers in the figure

[0080] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0081] The inventor has conducted a long period of research and experiment on a layered pre-pressing and packaging machine for improving the quality of tobacco leaf aging, mainly focusing on the following two aspects:

[0082] First, to verify that changing the one-time molding and single-piece packaging form to a small-volume multiple molding and multi-piece combined packaging form can substantially improve the aging quality of tobacco leaves, the inventors used existing equipment to conduct a long period of simulated production testing and comparative testing. The specific test data are shown in Table 1 (test results of the variation range of the content of cedarwood degradation products).

[0083] Table 1 shows the test results of the content variation of ceramidine degradation products

[0084]

[0085] As shown in Table 1, it can be seen from the change range of the content of cypermethrin degradation products that when the aging time is 6 months, except for the horizontal three-layer sample, the change range of the other layered and grid samples is significantly greater than that of the control sample, indicating that during the 0-6 month aging period, the aging reaction of the layered and grid samples is more intense than that of the control sample. When the aging time is 10 months, except for the horizontal four-layer sample, the change range of the other layered and grid samples is significantly greater than that of the control sample, indicating that during the 10-month aging period, the aging reaction of the layered and grid samples is more intense than that of the control sample. It can be seen that the use of layered and grid packaging for tobacco leaves is conducive to improving the aging quality and aging rate of tobacco leaves.

[0086] Second, the problem of maintaining production efficiency and reducing equipment costs. Specifically, if the layered packaging technology only changes the original one-time molding and single-piece packaging form to a small-volume multiple molding and multi-piece combined packaging form, but if the original production method is used with only minor modifications, the production efficiency will easily be greatly reduced. Therefore, it is necessary to improve the layered packaging technology as a whole.

[0087] In order to solve the defects of the prior art and the practical problems of the above-mentioned layered packaging, the present invention provides a layered pre-pressing and packaging integrated machine for improving the aging quality of tobacco leaves.

[0088] The basic concept of the layered pre-pressing and baling machine described in the present invention includes: using a set of equipment to replace the functions of the three equipments of the original workshop, namely the pre-pressing machine, the re-pressing machine and the slicer, to optimize and adjust the production process of the original imported equipment, and to avoid the crushing of the tobacco leaves caused by the slicer when cutting the formed tobacco leaves.

[0089] Example 1 Operation of six main mechanical components in a layered pre-pressing and packaging machine for improving tobacco leaf aging quality

[0090] In a specific embodiment, a layered pre-pressing and packaging integrated machine for improving the quality of tobacco leaf aging is composed of multiple parts, and each part works in a specific order to ensure uniform compaction and packaging of tobacco leaves, thereby improving the aging effect. Figure 1 As shown, a layered pre-pressing and packaging integrated machine for improving the aging quality of tobacco leaves includes a material unloading section group 1, a pre-pressing machine section group 2, a material pushing section group 3, a layered box lifting section group 4, a box turning and unloading section group 5, and a material unloading push rod section group 6.

[0091] The unloading section group 1 is the first station, through which tobacco leaves are fed into the machine and connected to other parts through a horizontal conveying system; the pre-pressing machine section group 2 is located in the central part of the machine, and is arranged after the unloading section group 1, so that the pre-pressing machine section group 2 is vertically aligned with the unloading section group 1, and is directly connected downward to the pushing section group 3, where the pre-pressing section group 2 compresses the tobacco leaves; the pushing section group 3 is immediately below the pre-pressing section group 2, and the pushing section group 3 will push the pre-pressed tobacco leaves into the box turning unloading section group 5; the box turning unloading section group 5 is located at the pushing section group Below or beside the part group 3, the box turning and unloading part group 5 receives the tobacco leaves from the pushing part group 3, and turns and redistributes them so that the tobacco leaves can enter the stratification box evenly; the stratification box lifting part group 4 is arranged below or near the box turning and unloading part group 5, and is used to adjust the layers of the tobacco leaves in the stratification box, and can be moved up and down to adapt to different aging stages; the unloading push rod part group 6 is located on the side of the machine, and is used to push the processed tobacco leaves out of the machine; the unloading cylinder 23 is at the bottom of the machine, which indicates that the carton 24 is used to collect the packaged tobacco leaves.

[0092] In a specific embodiment, a layered pre-pressing and packaging integrated machine for improving the aging quality of tobacco leaves needs to go through seven stages, namely, tobacco leaf entry and transportation, tobacco leaf pre-pressing, pushing of tobacco bricks / tobacco blocks, turning over and unloading of tobacco bricks / tobacco blocks, lifting and adjustment of the layered box, pushing out and packaging of tobacco bricks / tobacco blocks, and collection and packaging of finished tobacco blocks.

[0093] S1. Tobacco leaf entry and transportation: Tobacco blocks first enter the unloading section 1 through the feeding system; here, tobacco leaves enter the system quantitatively through the tobacco leaf conveyor 7; the electric roller material distribution section 8 is responsible for evenly distributing the tobacco leaves on the reciprocating belt conveyor 9 to prevent the tobacco blocks from piling up or unevenly distributed; the reciprocating belt conveyor 9 then evenly transports the tobacco blocks to the pre-pressing part of the machine. This transportation process ensures that the tobacco blocks can be evenly compacted in the subsequent processing process;

[0094] S2. Pre-pressing tobacco leaves: When the tobacco leaves reach the pre-pressing machine group 2, the pre-pressing electric cylinder 12 is activated to push the pressing head group 10 downward; the pressing head group 10 compacts the tobacco leaves to a predetermined specification and weight to form a compact tobacco brick / block. The pre-pressing process ensures the quality and uniformity of the tobacco brick / block in subsequent processing;

[0095] S3. Pushing of tobacco bricks (tobacco leaves): The pre-pressed tobacco bricks / blocks then enter the pushing section group 3; the horizontal pushing cylinder 14 is started to push the pushing seat 13 forward, so that the compacted tobacco bricks / blocks are pushed along the horizontal path to the box turning and unloading section group 5: The key to the pushing section group 3 is to ensure that the tobacco bricks / blocks are accurately pushed to the next processing stage and the integrity and correct positioning of the tobacco blocks are maintained;

[0096] S4. Turning over and unloading of cigarette bricks / cigarette blocks: the box turning and unloading section group 5 receives the cigarette bricks / cigarette blocks from the pushing section group 3; the box turning pushing cylinder 15 is then started to turn over the layered inner box 20 to ensure that the cigarette bricks / cigarette blocks can be evenly distributed in the layered inner box 20; the turning process enables the cigarette bricks / cigarette blocks to be stored vertically in each layer of the layered inner box and then loaded into the paper cigarette box. This vertical storage method has been proven to improve the aging effect of the cigarette bricks / cigarette blocks.

[0097] S5. Lifting and adjustment of the layered box: The layered box lifting unit 4 is located below the box turning and unloading unit 5, and is responsible for adjusting the layers of the cigarette blocks in the layered inner box; the lifting and lowering movement of the layered inner box 20 and the layered box sleeve 16 is controlled by the lifting unit 19; the baffle plate 17 and the baffle plate opening and closing cylinder 18 work together to ensure that the baffle plate can be automatically opened or closed when the cigarette bricks / cigarette blocks reach the specified layer, so that the cigarette bricks / cigarette blocks can be accurately positioned and pushed into each layer;

[0098] S6. Pushing out and packing of cigarette bricks / blocks: After the cigarette bricks / blocks have been layered and turned over, the unloading push rod group 6 is started; the unloading cylinder 23 drives the pressing head group 21 to push out the processed cigarette bricks / blocks from the layered inner box 20 and transfer them to the packing area; the action of the unloading cylinder 23 ensures that each layer of cigarette bricks / blocks can be smoothly pushed from the layered inner box 20 to the designated packing position, ready for final packaging processing;

[0099] S7. Collection and packaging of finished tobacco leaves: The processed tobacco bricks / blocks are finally pushed to the discharge cylinder tobacco box 23 at the bottom of the machine, where they will be collected into the pre-prepared paper tobacco box 23 to complete the final packaging process; the packaged tobacco bricks / blocks can then be sent to the next link for storage or transportation.

[0100] A layered pre-pressing and packaging machine that improves the quality of tobacco leaf aging. Through the close cooperation of six parts, it ensures the precise execution of each link of tobacco leaves from initial material leveling, pre-pressing, pushing, box turning, layering to final pushing out and packaging. The whole process has a high degree of automation, which not only improves the compaction quality of tobacco blocks, but also ensures the stability of aging effect.

[0101] Furthermore, in a layered pre-pressing and packaging machine for improving the quality of tobacco leaf aging, the six mechanical components are usually connected by mechanical connectors such as mechanical arms, shafts, slide rails, and hydraulic or pneumatic systems. The specific connection method depends on the relative position of each component and the predetermined workflow. Figure 1 As shown in the figure, the structural layout of the entire machine is designed to achieve a continuous and automated workflow to improve the efficiency and quality of tobacco leaf aging.

[0102] In a layered pre-pressing and packaging integrated machine for improving the aging quality of tobacco leaves, each of the six main mechanical components, namely, a material unloading group 1, a pre-pressing machine group 2, a material pushing group 3, a layered box lifting group 4, a box turning unloading group 5, and a material unloading push rod group 6, and their specific functions are as follows:

[0103] Cutting group 1: like Figure 2 As shown, a material unloading group 1 of a layered pre-pressing and baling integrated machine for improving the aging quality of tobacco leaves includes a reciprocating belt conveyor group 7, an electric roller material distribution group 8 and a reciprocating belt conveyor group 9. The unloading group 1 is the entrance part of the equipment. Through the coordinated work of components such as conveyor belts, guide plates and vibrating feeders, it ensures that tobacco leaves enter the equipment evenly and stably for pre-pressing and subsequent processing. It is closely connected with other groups and relies on the electrical control system for automatic operation and monitoring to ensure the smoothness of the entire production process and the processing quality of tobacco leaves.

[0104] The unloading section group 1 is located on the left side or front end of the equipment and is the entrance part of the entire equipment; the unloading section group 1 is fixed to the ground or the base of the equipment through a supporting frame to ensure its stability; one end of the conveyor belt is connected to the external raw material supply system, and the other end is connected to the pre-pressing machine section group 2.

[0105] The reciprocating belt conveyor group 9 is the core component of the unloading group, and tobacco leaves are fed into the machine from the outside through the conveyor belt on the reciprocating belt conveyor group 9. The conveyor belt material of the reciprocating belt conveyor group 9 is rubber or plastic, which is wear-resistant; the conveyor belt drive device is driven by an electric motor and connected to the electrical control system, and the continuous automatic operation of the conveyor belt is realized through gear or belt transmission; the conveyor belt bracket is used to fix the conveyor belt and keep the conveyor belt running smoothly. The conveyor belt is a rectangular plane with a moderate width, which can accommodate a sufficient amount of tobacco leaves; the length and width of the conveyor belt can be replaced, which is determined by the overall design of the equipment and the required processing volume. The conveyor belt system is horizontally arranged at the leftmost end or front end of the machine to directly receive external tobacco leaf raw materials.

[0106] The guide plate of the reciprocating belt conveyor unit 9 is used to guide the tobacco leaves into the conveyor belt and prevent the tobacco leaves from scattering; the guide plate material is metal or hard plastic, which can prevent the tobacco leaves from piling up and getting stuck. The reciprocating belt conveyor unit 7 is provided with a chute with adjustable height and angle, and its inclination can be adjusted according to the volume and quantity of the tobacco leaves to ensure smooth transmission. The guide plate and chute are located at the starting point or middle part of the conveyor belt, usually in a curved shape, so that the tobacco leaves can slide smoothly into the conveyor belt; the guide plate or chute is installed above or on the side of the conveyor belt, and is fixed to the support frame of the conveyor belt by bolts or welding.

[0107] Optionally, the unloading section 1 further includes a vibrating feeder to ensure that the tobacco leaves are evenly distributed on the conveyor belt of the reciprocating belt conveyor section 7; the vibrating feeder generates periodic vibrations through a vibrating motor to prevent tobacco leaves from clogging; the vibrating feeder is installed above the guide plate or the conveyor belt to provide an additional uniform distribution function. The vibrating feeder is connected to the guide plate or the chute to form an integral feeding system and is fixed above the conveyor belt by a bracket.

[0108] Optionally, the blanking part group 1 also includes a support frame, which can support the structure of the entire blanking part group 1, usually made of metal material, fixed on the overall frame of the machine to ensure its stability; the support frame is made of steel or aluminum alloy to ensure the firmness and durability of the equipment.

[0109] The connection relationship and coordination principle between the unloading group 1 and other components are as follows: the end of the unloading group 1 is directly connected to the pre-pressing machine group 2, and the conveyor belt will smoothly transport the tobacco leaves to the entrance of the pre-pressing machine group 3; the pre-pressing machine group 2 will detect the arrival of the tobacco leaves and start its compression process. The operating parameters of the unloading group, such as the conveyor belt speed and the frequency of the vibrating feeder, are automatically adjusted by the electrical control system to ensure the flow and uniformity of the tobacco leaves. The unloading group 1 is connected to the external feeding system through a conveyor belt or other conveying device. The external system can be a manual feeding, an automated storage system or a raw material warehouse.

[0110] The working principle of the unloading section group 1 is as follows: First, tobacco leaves are transported. Tobacco leaves enter the unloading section group 1 from the external feeding system and are guided into the conveyor belt system by a conveyor belt or a chute; the conveyor belt is driven by a motor to transport the tobacco leaves horizontally to the pre-pressing machine section group 2. Second, the tobacco leaves are evenly distributed. The vibrating feeder or guide plate ensures that the tobacco leaves are evenly distributed on the conveyor belt to avoid accumulation or deviation. Third, precise transmission control is achieved. The speed of the conveyor belt and the vibration frequency of the vibrating feeder are automatically adjusted according to the overall processing rhythm of the equipment to ensure the continuous transmission and processing efficiency of the tobacco leaves.

[0111] Example 2 Application of the unloading unit 1 in the cigarette block packaging production line

[0112] In a specific embodiment, the specific application and operation steps of the material group 1 in the tobacco block packaging production line focus on utilizing the various components in the material group 1 to achieve efficient and uniform transmission of tobacco leaves, and provide a stable supply of raw materials for the subsequent pre-pressing and packaging processes. Through the material group 1 in this embodiment, the tobacco block packaging production line can achieve efficient and stable tobacco leaf transmission, ensuring that the tobacco leaves are evenly distributed and smoothly enter the pre-pressing process. The application of the electric roller material distribution group 8 and the vibrating feeder further improves the processing quality of tobacco leaves, reduces the risk of blockage and accumulation, enables the tobacco block packaging production line to operate at a higher efficiency, and ensures that the quality of the tobacco leaf blocks after final packaging meets the requirements.

[0113] S1. Receiving and preliminary conveying of tobacco blocks: First, when the tobacco block packaging production line starts, the tobacco leaves enter the unloading section 1 through the external feeding system. The feeding system may include an automated storage system or a raw material warehouse. The feeding system mechanically puts the tobacco blocks into the conveyor belt system; one end of the conveyor belt is connected to the external raw material supply system, and the other end is connected to the pre-pressing machine section 2. Then, after the tobacco leaves enter the conveyor belt, the reciprocating belt conveyor section 9 is responsible for the preliminary conveying; the conveyor belt is made of rubber or plastic, is wear-resistant, and can withstand long-term continuous operation. Driven by the motor, the conveyor belt transfers the tobacco leaves to the next processing position at a set speed; the speed of the conveyor belt is monitored and adjusted in real time by the electrical control system to match the rhythm of the entire tobacco block packaging production line to avoid blockage or accumulation caused by too fast or too slow.

[0114] S2. Uniform distribution of tobacco leaves: During the transmission process, in order to ensure the uniform distribution of tobacco leaves, the vibrating feeder and the guide plate work together; the vibrating feeder disperses the tobacco leaves evenly on the conveyor belt through periodic vibration to prevent the tobacco leaves from piling up or deviating during the transmission process; and the guide plate is set at the starting point or middle part of the conveyor belt. By adjusting its height and angle, it can ensure that tobacco leaves of different volumes and thicknesses slide evenly into the conveyor belt, thereby further improving the uniformity of distribution. Then, after passing through the conveyor belt system, the tobacco leaves enter the electric roller material distribution group 8. The electric roller material distribution group 8 uses multiple groups of electric brush rollers or electric rollers to further disperse and flatten the tobacco leaves. The two rows of electric rollers spread the tobacco leaves evenly through synchronous rotation to ensure that the tobacco leaves will not be blocked or piled up before entering the next link. The speed and angle of the electric roller are also automatically adjusted by the electrical control system to adapt to tobacco leaves of different batches and thicknesses to ensure the uniformity and smoothness of transmission.

[0115] S3. Accurate transmission and processing of tobacco leaves: Through the electrical control system, the conveyor belt speed of the unloading group 1, the vibration frequency of the vibrating feeder and other parameters can be automatically adjusted according to the predetermined process requirements to ensure the flow and uniformity of the tobacco leaves. This ensures that each batch of tobacco blocks can be transmitted to the pre-pressing machine group 2 in a stable state for the next step of processing. If tobacco leaf accumulation or uneven transmission is detected during the production process, the system will automatically adjust the working state of the conveyor belt and the vibrating feeder to ensure the stability of the transmission. At the same time, after the tobacco leaves are evenly distributed, the conveyor belt transfers them to the entrance of the pre-pressing machine group 2, ready for pre-pressing. In this process, the task of the unloading group 1 is to ensure that the tobacco leaves remain uniform and stable during transmission and will not affect the working efficiency of the pre-pressing machine.

[0116] S4. Connection with pre-pressing and packaging in subsequent groups: After the tobacco leaves enter the pre-pressing group 2, they are compacted and block-formed. After the pre-pressing is completed, the tobacco bricks / blocks will be pushed to the pushing group 3, and then enter the box turning and unloading group 5 for the final packaging process.

[0117] The entire unloading group 1 is closely connected with the subsequent pre-pressing group 2 and other groups, and through the coordination of the electrical control system, it ensures the smooth transmission and efficient processing of the tobacco blocks in each processing link.

[0118] Pre-pressing machine group 2: The pre-pressing machine group 2 is one of the key components in the entire equipment, and its main function is to pre-compress the tobacco leaves to reduce their volume and prepare for the subsequent compression and layered packaging steps. The pre-pressing machine group 2 achieves this process by applying a certain pressure, and is usually driven by a hydraulic or pneumatic system. The pre-pressing machine group 2 drives the compression device through a hydraulic or pneumatic system to pre-compress the tobacco blocks. This process not only reduces the volume of the tobacco leaves, but also prepares for the subsequent box turning, layering and packaging operations. The pre-pressing machine group 2 works closely with the unloading group 1, the pushing group 3 and the electrical control system to ensure the continuity and efficiency of the entire tobacco brick / tobacco block processing process.

[0119] like Figure 3 As shown, a pre-pressing and packing unit 2 of a layered pre-pressing and packing integrated machine for improving the quality of tobacco leaf aging includes a pre-pressing electric cylinder 9, a pressing head unit 10, and a frame unit 11. The pre-pressing electric cylinder 9 can perform preliminary compaction on the tobacco block in preparation for packing. The pressing head unit 10 and the frame unit 11 can support and guide the pressing head to perform accurate compression operations.

[0120] The pre-stressing electric cylinder 9 is a cylindrical electric cylinder, which is installed on the top of the equipment, provides compression power through a driving motor, and is directly connected to the pressing head group 10; the pre-stressing electric cylinder 9 provides power for pre-compression of the tobacco block, and is responsible for pushing the pressing head group 10 to compact the tobacco leaves; the pre-stressing electric cylinder 9 is cylindrical, installed on the top of the equipment, and controls the up and down movement of the pressing head group through a driving shaft; the pre-stressing electric cylinder 9 is driven by an electric motor, and contains a reducer and a threaded mechanism to ensure precise control of the compression force and compression stroke; the pre-stressing electric cylinder 9 is installed above the frame group, and is connected to the pressing head group 10 through a connecting piece to ensure that the pressing head can move up and down with the movement of the pre-stressing electric cylinder 9.

[0121] The pressing head group 10 is a large-area flat-plate pressing head, which is installed below the pre-stressing electric cylinder 9 and located above the tobacco leaf stacking area; the pressing head group 10 is a component that directly contacts the tobacco block, and applies pressure to the tobacco leaves through the push of the pre-stressing electric cylinder 9 to achieve the pre-compression function; the pressing head of the pressing head group 10 is a large-area rectangular or square flat plate, made of high-strength metal material, and can withstand the high pressure during the compression process; the pressing head group 10 is located in the middle of the pre-stressing packaging group 2 and is directly suspended below the pre-stressing electric cylinder 9; the pressing head group 10 is connected to the end of the pre-stressing electric cylinder 9 through a connecting piece, and moves up and down with the telescopic movement of the pre-stressing electric cylinder 9.

[0122] The frame group 11 is a multi-column frame structure, which surrounds and supports the entire pre-pressing machine group 2 to ensure the stability of the entire system; the frame group 11 provides support for the pre-pressing electric cylinder 9 and the pressure head group 10, and ensures that the pressure head remains stable and vertical during the compression process; the frame group 11 also provides guidance for the movement of the pressure head to prevent it from shifting; the frame group 11 is a four-column or multi-column structure, made of a sturdy metal frame, and can withstand the huge pressure generated by the pre-pressing machine group 2 during the compression process; a guide rod or slide rail is provided in the frame group 11 to ensure that the movement trajectory of the pressure head is vertical and stable; the frame group 11 surrounds the entire pre-pressing electric cylinder 9 and the pressure head group 10, and is fixed in the central area of ​​the main frame of the equipment to ensure a stable connection between the frame group 11 and other components.

[0123] The guide device 25 is a guide rod or a slide rail installed on the inner side of the frame, and is closely matched with the pressure head group 10 to ensure its stability and accuracy during movement; the guide device 25 is used to ensure that the pressure head of the pressure head group 10 maintains a stable vertical direction during the up and down movement to prevent deviation or tilt, thereby ensuring the uniformity of compression; the guide device 25 is composed of a plurality of guide rods or slide rails, which are fixed to the frame group 11 and pass through the slide groove or slider of the pressure head group 10 to ensure the stable movement of the pressure head group 10; the guide device 25 is installed on the inner side of the frame group 11, connected to the pressure head group 10, and provides movement guidance for the pressure head.

[0124] The connection relationship between the pre-stressing electric cylinder 9 and the pressure head group 10 is that the pre-stressing electric cylinder 9 is fixed to the pressure head group 10 by a connecting rod or a flange, providing a vertical driving force to push the pressure head to move up and down; the connection relationship between the pressure head group 10 and the frame group 11 is that the pressure head group 10 is connected to the guide device 25 in the frame group 11, and is guided by a guide rod or a slide rail to ensure the verticality and stability of the pressure head movement; the connection relationship between the frame group 11 and the equipment body is that the frame group 11 is fixed on the main frame of the equipment, and its stability and durability are ensured by bolts or welding.

[0125] The coordination relationship between the pre-pressing machine group 2 and the unloading group 1 is that the pre-pressing machine group 2 is located directly above the unloading group 1, ensuring that the tobacco leaves transferred from the unloading group 1 can smoothly enter the working area of ​​the pressing head for pre-compression processing. The coordination relationship between the pre-pressing machine group 2 and the pushing group 3 is that the compressed tobacco blocks are pushed into the box turning unloading group 5 by the pushing group 3 through the lower opening of the pre-pressing machine group 2 for subsequent processing; the actions of the pushing group 3 and the pressing head group 10 are coordinated with each other to ensure the continuity of tobacco block processing. The coordination relationship between the pre-pressing machine group 2 and the electrical control system is that the pre-pressing electric cylinder 9, pressure sensor and other components are monitored and operated through the electrical control system; the control system adjusts the action and compression force of the pre-pressing electric cylinder 9 in real time to ensure the stability and accuracy of the pre-pressing process.

[0126] The working principle of the pre-pressing machine group 2 is to transfer and position the tobacco blocks and to compress the tobacco blocks. When the unloading group 1 delivers the tobacco blocks to the bottom of the pressure head of the pre-pressing machine group 2, the control system of the pre-pressing machine group 2 receives the position signal and starts the pre-pressing electric cylinder 9 to perform the compression operation. The pre-pressing electric cylinder 9 drives the pressure head group 10 to move downward and applies pressure to compact the tobacco leaves; the guide device 25 ensures that the movement trajectory of the pressure head is vertically stable to prevent deviation and ensure uniform compression of the tobacco leaves. During the compression process, the pressure sensor monitors the compression force in real time and feeds back to the control system. The system adjusts according to the preset value to ensure the safety and efficiency of the compression process. After the compression process is completed, the pre-pressing electric cylinder 9 lifts the pressure head back to the initial position, and the pushing group 3 starts to work, pushing the compressed tobacco leaves into the box turning and unloading group 5 to enter the next step of processing.

[0127] The pre-pressing machine group 2 realizes the pre-compression processing of tobacco leaves through the close cooperation of the pre-compression electric cylinder 9, the pressing head group 10, the frame group 11 and the guide device 25. This process not only reduces the volume of the tobacco block, but also prepares for the subsequent box turning, layering and packaging operations. The pre-pressing machine group 2 closely cooperates with the unloading group 1, the pushing group 3 and the electrical control system to ensure the continuity and efficiency of the entire tobacco leaf processing process.

[0128] Example 3 Application of the pre-pressing machine group 2 in the cigarette block packaging production line

[0129] In a specific embodiment, the specific operation process of the pre-pressing machine group 2 in the cigarette block packaging production line shows how to achieve pre-compression processing of tobacco leaves through the cooperation of the pre-pressing electric cylinder 12, the pressing head group 10, the frame group 11 and the guide device 25, providing a solid foundation for the subsequent box turning, layering and packaging operations. This embodiment shows the key role of the pre-pressing machine group 2 in the cigarette brick / cigarette block packaging production line. Through the precise cooperation of the pre-pressing electric cylinder 12, the pressing head group 10, the frame group 11 and the guide device 25, the pre-pressing machine group 2 can efficiently compress the tobacco leaves into cigarette bricks / cigarette blocks that meet the requirements, laying a solid foundation for subsequent pushing and packaging operations. In the entire production line, the stable operation of the pre-pressing machine group 2 ensures the continuity and efficiency of the tobacco leaf processing process, and ultimately improves the quality and production efficiency of the finished cigarette bricks / cigarette blocks.

[0130] The pre-pressing machine assembly 2 includes a pre-pressing electric cylinder 9, a pressing head assembly 10, a frame assembly 11 and a guide device 25; the pre-pressing electric cylinder 9 is installed on the top of the equipment, and provides compression power through a driving motor to drive the pressing head assembly 10 to move up and down; the frame assembly 11 serves as the supporting structure of the entire pre-pressing machine assembly 2, ensuring the stability of the pre-pressing machine assembly 2 and the smoothness of the compression process; the guide device 25 is used to ensure the stability and verticality of the pressing head assembly 10 during movement.

[0131] The connection between the pre-pressing machine group 2 and the unloading machine group 1 is that the unloading machine group 1 is responsible for evenly conveying the tobacco leaves to the bottom of the pressing head of the pre-pressing machine group 2; the conveyor belt accurately positions the tobacco leaves in the working area of ​​the pressing head to ensure that the tobacco leaves can be smoothly compressed after entering the pre-pressing machine group 2. The pre-pressing machine group 2 is directly connected to the pushing machine group 3, and the tobacco bricks / blocks compressed by the pre-pressing machine group 2 will enter the pushing machine group 3 through the lower opening of the pre-pressing machine. The pushing machine group 3 is responsible for pushing the compressed tobacco bricks / blocks to the box turning unloading machine group 5 for the next step of processing.

[0132] In the cigarette block packaging production line, the cigarette brick / cigarette block pre-compression process is as follows:

[0133] S1. Conveying and positioning of tobacco leaves: During the operation of the tobacco brick / block packaging production line, tobacco leaves enter the pressing head area of ​​the pre-pressing machine group 2 through the conveyor belt of the unloading group 1; the conveyor belt evenly distributes the tobacco leaves under the pressing head group 10, and the sensor detects the arrival signal of the tobacco leaves and notifies the electrical control system to prepare to start the pre-pressing process;

[0134] S2. Start the pre-pressing electric cylinder 9: After receiving the sensor signal, the control system starts the pre-pressing electric cylinder 9; the pre-pressing electric cylinder 9 pushes the pressing head group 10 downward through the driving shaft, and applies pressure to compress the tobacco leaves; the reducer and threaded mechanism in the pre-pressing electric cylinder 12 ensure the precise control of the pressing head movement, and the compression force and stroke are adjusted according to the preset values ​​to adapt to tobacco leaves of different thicknesses and densities;

[0187] Example 6 Application of the layered box lifting unit group 4 in the cigarette block packaging production line

[0188] In a specific embodiment, the specific operation process of the layered box lifting group 4 in the cigarette block packaging production line shows that through the cooperation of the layered inner box 20, the layered box sleeve 16, the baffle plate 17, the baffle plate opening and closing cylinder 18 and the lifting group 19, the cigarette blocks are accurately distributed and processed in different layers, thereby improving the quality of cigarette block aging.

[0189] The structure of the stratified box lifting unit group 4 is as follows: the stratified box sleeve 16 is a rectangular or square shell, which is used to wrap the stratified inner box 20 and play a supporting and protective role; the stratified box sleeve 16 is installed on the support plate of the lifting unit group 19, and the lifting movement is realized through the lifting unit group 19. The stratified inner box 20 is a container for carrying tobacco bricks / cigarette blocks, and multiple compartments are provided inside for storing tobacco bricks / cigarette blocks of different layers; the stratified inner box 20 is installed inside the stratified box sleeve 16, and is lifted and lowered together with the stratified box sleeve 16 to ensure that the tobacco bricks / cigarette blocks can be evenly distributed in different layers.

[0191] The stratification processing operation process of the stratification box lifting unit group 4 is as follows:

[0192] S1. Receiving and adjusting the height of cigarette blocks: When the box turning and unloading unit 5 delivers the turned cigarette bricks / cigarette blocks to the layered box lifting unit 4, the electrical control system instructs the lifting unit 19 to adjust the height of the layered inner box 20. The lifting unit 19 drives the layered box cover 16 and the layered inner box 20 inside it to move up and down through an electric cylinder or a hydraulic cylinder, so that the top of the layered inner box 20 is aligned with the inlet of the cigarette blocks. The layered box cover 16 protects the layered inner box 20 and ensures the stability of the layered inner box 20 and the smoothness of the lifting movement.

[0193] S2. Opening and closing of the baffle plate 17 and distribution of tobacco blocks: As the layered inner box 20 reaches the specified height, the electrical control system instructs the baffle plate opening and closing cylinder 18 to start and control the opening and closing of the baffle plate 17. The baffle plate 17 opens at an appropriate time to allow tobacco bricks / cigarette blocks to fall into different compartments of the layered inner box 20 in sequence. During the process of dropping tobacco blocks, the opening and closing of the baffle plate 17 is precisely controlled by the electrical control system to ensure that the tobacco bricks / cigarette blocks are evenly distributed in each layer and avoid accumulation or offset in the layered inner box 20.

[0194] S3. Layer-by-layer distribution and storage: Each layer of the layered inner box 20 will receive the cigarette bricks / cigarette blocks in turn, and the electrical control system will adjust the height of the layered inner box 20 layer by layer according to production requirements. When one layer of cigarette bricks / cigarette blocks is full, the lifting unit 19 will lower the layered inner box 20 to the feeding position of the next layer, and the baffle plate 17 will open again to allow the cigarette bricks / cigarette blocks to enter the new layer. Layer-by-layer processing ensures that each layer of cigarette blocks is evenly distributed and optimizes the effect of cigarette bricks / cigarette blocks during the aging process.

[0195] S4. Completion of layering and preparation for the next processing cycle: When all layers of cigarette bricks / cigarette blocks have been stored according to the set requirements, the lifting unit 19 adjusts the layered inner box 20 to the initial position and prepares to receive the next batch of cigarette bricks / cigarette blocks. The baffle plate 17 is closed to ensure that the cigarette bricks / cigarette blocks are stably stored in the layered inner box 20. After the cigarette bricks / cigarette blocks in the layered inner box 20 are evenly distributed, the subsequent alcoholization treatment can be carried out to ensure that the alcoholization effect of each layer of cigarette bricks / cigarette blocks is consistent.

[0196] In the entire tobacco block packaging production line, the layered box lifting group 4 cooperates closely with the box turning and unloading group 5 and other groups, so that the entire tobacco block packaging production line process maintains a smooth transition between each link. Through the precise operation of the layered box lifting group 4, the tobacco block packaging production line can ensure the uniform distribution and stable storage of tobacco blocks, and ultimately improve the aging effect and production efficiency. All operations of the layered box lifting group 4 are uniformly managed by the electrical control system. According to production requirements, the tobacco block packaging production line accurately controls the actions of the lifting group 19 and the baffle plate opening and closing cylinder 18 to ensure 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 leaf blocks can be accurately distributed in the corresponding compartment.

The conveyor belt evenly transports the tobacco leaves to the unloading section 1; under the action of the roller arrangement system, the tobacco leaves are evenly distributed on the conveyor belt to avoid accumulation or deviation. The sensor monitors the flow and speed of the tobacco leaves in real time. When the tobacco flow is too large or accumulated, the sensor feeds back the signal to the control system, and the control system adjusts the running speed of the electric roller to ensure the smoothness of the conveying process. The entire tobacco conveying process is automatically managed by the electrical control system to ensure that the speed of the conveyor belt and the tobacco flow match the processing speed of the subsequent process, ensuring the continuity and efficiency of the production process.

[0228] The tobacco leaf conveyor 7 is connected to the feeding system through a conveyor belt. The feeding system evenly inputs the tobacco blocks onto the conveyor belt according to production requirements, and the tobacco leaf conveyor 7 receives these tobacco leaves and conveys them to the unloading section group 1.

[0229] The tobacco conveying operation process of the tobacco conveyor 7 is as follows:

[0230] S1. Start of receiving and conveying cigarette blocks: When the feeding system feeds the conveyor belt, the electric roller starts, drives the conveyor belt to run at the set speed, and starts to convey the cigarette blocks from the feeding system to the unloading group 1; the roller arrangement system ensures that the cigarette blocks are evenly distributed on the conveyor belt to prevent the cigarette blocks from piling up or shifting during the conveying process.

[0231] S2. Tobacco flow and speed regulation: During the conveying process, the sensor system monitors the flow and speed of tobacco leaves in real time and feeds back the data to the electrical control system; when the sensor detects that the flow of tobacco blocks is too large or accumulated, the electrical control system adjusts the running speed of the electric roller according to the feedback signal, reduces the speed of the conveyor belt or suspends the conveying to avoid blockage or uneven distribution of tobacco blocks; real-time monitoring of the sensor system and automatic adjustment of the electrical control system ensure the smoothness and continuity of the tobacco block conveying process.

[0232] S3. The tobacco blocks enter the unloading group 1: The tobacco blocks are evenly transported to the unloading group 1 through the conveyor belt and enter the subsequent pre-pressing and packaging process; due to the uniform distribution and precise control during the transportation process, the tobacco blocks can enter the unloading group 1 in an ideal state, providing a stable supply of raw materials for subsequent processing.

[0233] In the entire tobacco block packaging production line, the tobacco conveyor 7 works closely with the feeding system and the unloading group 1, so that the entire production process maintains a smooth transition between various links.

The frame support structure provides reliable structural support for the entire conveying process, ensuring the stability of the tobacco conveyor 7 during operation, and avoiding the influence of conveying efficiency due to equipment vibration or deviation.

[0234] All operations of the tobacco conveyor 7 are centrally managed by the electrical control system. The electrical control system accurately controls the start and stop of the motorized roller and the running speed of the conveyor belt according to production requirements, ensuring that the tobacco block conveying process is consistent with the working rhythm of other links of the production line. The electrical control system monitors the flow and speed information fed back by the sensor system in real time, automatically adjusts the conveying speed, and ensures a smooth and efficient conveying process.

[0235] Important components of the material unloading group 1: the electric roller material distribution group 8

[0236] The electric roller material distribution group 8 is a key component in the layered pre-pressing and packaging machine, and is located below the discharge port of the tobacco conveyor 7 and above the reciprocating belt conveyor 9; the main function of the electric roller material distribution group 8 is to evenly distribute the tobacco leaves falling from the tobacco conveyor 7 through multiple groups of electric brush rollers or electric rollers, ensuring that the tobacco leaves will not be piled up or uneven before entering the next stage of processing. The electric roller material distribution group 8 achieves even distribution of the tobacco leaves after they fall from the tobacco conveyor 7 through the coordination of the electric brush rollers, transmission system, adjustment device, support frame and electrical control system; the electric brush roller spreads the tobacco leaves evenly through rotation, the adjustment device ensures that the brush roller can adapt to tobacco leaves of different thicknesses, and the electrical control system accurately controls the entire material distribution process to ensure that the tobacco leaves reach an ideal distribution state before entering the next process.

[0237] The electric brush roller is a long cylindrical structure with a brush or rubber coating on the surface. It is arranged below the discharge port of the tobacco conveyor 7 and is responsible for the uniform distribution of the tobacco leaves.

[0238] The transmission system is composed of a chain or belt transmission system, connected to the drive shaft of the electric brush roller, and installed on one side or the bottom of the electric brush roller. The transmission system drives multiple groups of electric brush rollers through a motor to rotate at a set speed, thereby achieving uniform distribution of tobacco leaves. The transmission system can be a chain or belt transmission, connecting the drive shafts of each electric brush roller to ensure that each electric brush roller rotates synchronously; the transmission system is usually composed of a motor, a transmission chain, a gear or a belt, and has a compact structure, which can transmit the power of the motor to each electric brush roller; the transmission system is installed on one side or the bottom of the electric brush roller, and is connected to the drive shaft of each electric brush roller.

[0239] The adjusting device is a height and angle adjusting device installed on both sides or the bottom of the electric brush roller, and is used to adjust the working position of the electric brush roller. The adjusting device is used to adjust the height and angle of the electric brush roller to adapt to different tobacco leaf thicknesses and processing requirements, thereby achieving the best material evenness effect; the adjusting device is an automatic adjusting mechanism, including a height adjusting bolt or a hydraulic cylinder, which can accurately adjust the working height and angle of the electric brush roller; the adjusting device is installed on both sides or the bottom of the electric brush roller, and the height and angle adjustment of the electric brush roller is achieved through the adjusting device.

[0240] The support frame is a metal frame structure, which is installed inside the box of the pre-pressing machine group 2, above the reciprocating belt conveyor group 7, and supports the electric brush roller and the transmission system; the support frame is used to support and fix the entire electric roller material distribution group 8 to ensure that it remains stable during operation; the support frame also provides a fixing point for the transmission system and adjustment device of the electric brush roller; the support frame is a metal frame structure, made of steel or aluminum alloy, and has sufficient strength and stability; the support frame is installed inside the box of the pre-pressing machine group 2, above the reciprocating belt conveyor group 9, and provides support and fixation for the electric brush roller.

[0241] The electrical control system is installed in the control cabinet, connected to the electric brush roller through a cable, and is responsible for controlling its operating state and speed. The electrical control system is responsible for controlling the rotation speed and operating state of the electric brush roller to ensure the automation of the uniform material distribution process; the electrical control system also cooperates with the control systems of other groups to ensure that the tobacco leaves are evenly distributed without affecting the working rhythm of the entire equipment; the electrical control system includes a control panel, relays, frequency converters and cables, etc., which can accurately control the rotation speed of the electric brush roller; the electrical control system is installed in the control cabinet of the equipment and connected to the electric brush roller through a cable.

[0242] The connection relationship between the electric brush roller and the transmission system is that the electric brush roller is connected to the motor through the transmission system, and the transmission system ensures that each electric brush roller rotates synchronously to achieve uniform distribution of tobacco leaves. The connection relationship between the electric brush roller and the adjustment device is that the adjustment device is connected to the two sides or the bottom of the electric brush roller, and can adjust the height and angle of the electric brush roller to adapt to different tobacco leaf thicknesses and processing requirements. The connection relationship between the electric brush roller and the support frame is that the electric brush roller is fixed to the support frame through a support structure, and the support frame ensures that the entire material distribution group remains stable during operation. The connection relationship between the electrical control system and the electric brush roller is that the electrical control system is connected to the electric brush roller through a cable to control the rotation speed and operating state of the electric brush roller.

[0243] The coordination relationship between the electric roller evenly distributed material distribution group 8 and the tobacco conveyor 7 is that the electric roller evenly distributed material distribution group 8 is located below the discharge port of the tobacco conveyor 7, and is responsible for evenly distributing the tobacco leaves falling from the conveyor to ensure that the flow rate and distribution of tobacco leaves entering the next stage are consistent. The coordination relationship between the electric roller evenly distributed material distribution group 8 and the reciprocating belt conveyor group 9 is that the electric brush roller transfers the evenly distributed tobacco leaves to the reciprocating belt conveyor group 9 to ensure that the tobacco leaves on the reciprocating belt conveyor group 9 are evenly distributed, thereby laying the foundation for subsequent pre-pressing and packaging operations. The coordination relationship between the electric roller evenly distributed material distribution group 8 and the electrical control system is that the electric roller evenly distributed material distribution group 8 is connected to the electrical control system, and the speed and operating state of the electric brush roller are adjusted by the electrical control system to ensure the even distribution of tobacco leaves and the synchronous operation of the system.

[0244] The working principle of the electric roller material distribution group 8 is to perform automated material distribution processing. When the tobacco leaves fall from the discharge port of the tobacco conveyor 7, the electric brush roller or electric roller starts to rotate to evenly disperse and spread the tobacco leaves. By adjusting the speed and height of the electric brush roller, it is ensured that the tobacco leaves will not pile up or be unevenly distributed. The electrical control system monitors the operating status of the electric brush roller in real time, and automatically adjusts the speed of the electric brush roller according to the working rhythm of the tobacco conveyor 7 to ensure that the tobacco leaves are evenly distributed without affecting the overall production rhythm. Finally, after the tobacco leaves are evenly distributed, they enter the reciprocating belt conveyor group 9 and are conveyed to the next process to realize subsequent pre-pressing and packaging operations.

[0245] The electric roller material distribution arrangement group 8 is arranged into two rows of electric rollers in order to enhance the tobacco block material distribution effect and reduce blockage and accumulation.

[0246] First, two rows of electric rollers can more effectively disperse and flatten tobacco leaves or tobacco blocks. The first row of rollers preliminarily disperses the material, and the second row further refines it so that the material can be more evenly distributed before falling. This can prevent the uneven distribution that may be caused by a single row of rollers. Specifically, the cooperative working principle of the two rows of electric rollers is as follows: first, achieve preliminary dispersion (the role of the first row of electric rollers). The first row of electric rollers is located at the initial position of the falling of tobacco leaves or tobacco blocks. When the tobacco block falls from the tobacco conveyor 7, the first row of electric brush rollers immediately starts to rotate, and the tobacco block is preliminarily dispersed through the brush or rubber coating on the surface of the electric brush roller. The main purpose of achieving preliminary dispersion is to break the aggregation of the tobacco block material, disperse the larger pieces of tobacco leaves or tobacco blocks, and make them preliminarily unfold in the conveying direction. Then, further refine the material (the role of the second row of electric rollers). After the tobacco block is preliminarily dispersed by the first row of electric brush rollers, it enters the processing area of ​​the second row of electric brush rollers. The second row of electric brush rollers continues to rotate, further dispersing the tobacco that was not fully spread out by the first row of electric brush rollers by further refining the tobacco. The purpose of further refining the material is to ensure that the tobacco can be spread out more evenly in both the horizontal and vertical directions to avoid any possible aggregation, thereby achieving uniform distribution of the tobacco.

[0247] On the contrary, if only one row of rollers is used, especially when handling larger tobacco blocks, the tobacco blocks will not be dispersed sufficiently due to the limited rotation force or angle of the electric brush rollers, resulting in the tobacco blocks being too concentrated in some areas and too sparse in other areas. The design of two rows of electric brush rollers can effectively eliminate the risk of uneven distribution through a two-step dispersion process.

[0248] Furthermore, the first row of electric brush rollers plays a role of "rough adjustment", that is, to initially disperse large pieces of tobacco blocks, while the second row of rollers plays a role of "fine adjustment" to make the distribution of tobacco blocks more accurate and uniform. The two rows of electric brush rollers work together to ensure that the tobacco block material has been fully homogenized before it finally falls into the next processing stage. In the efficient production environment of tobacco block packaging, processing speed and quality are both key indicators. Two rows of electric brush rollers can complete complex tobacco block dispersion and flattening tasks in a short time, thereby improving production efficiency. In addition, step-by-step processing can also reduce the pressure on a single electric brush roller and extend the service life of the equipment. In actual production lines, especially in the processing of tobacco leaves or tobacco blocks, the uniform distribution of tobacco block materials directly affects the quality and efficiency of subsequent processes (such as pre-pressing and packaging). Through the synergistic effect of the two rows of rollers set in the electric roller material distribution group 8, the production line can more stably maintain a high-quality tobacco block packaging process and reduce quality problems or production interruptions caused by uneven distribution of tobacco blocks. Two rows of motorized rollers effectively control the uniform distribution of the tobacco mass through the two steps of "initial dispersion" and "further refinement".

[0249] Secondly, the two-row motor roller can improve the ability to evenly process different batches of tobacco blocks. In terms of processing larger volumes of tobacco blocks, two rows of motor rollers can process larger volumes of tobacco leaves or tobacco blocks, because the dispersion and even processing of tobacco blocks is carried out in stages when they pass through the two rows of motor rollers. The first row of motor rollers is responsible for the initial expansion and dispersion, which can reduce the density of tobacco blocks so that they have been partially processed before entering the second row of motor rollers. The staged processing method enables the two-row motor rollers to have a stronger "digestion" ability, that is, they can more effectively process large volumes of tobacco blocks, and are not prone to tobacco block accumulation or blockage; thus, they can better cope with large batches or large volumes of tobacco blocks that suddenly appear in production. In terms of adapting to tobacco blocks of different thicknesses, the thickness of tobacco blocks varies depending on the batch, processing stage or humidity and type of tobacco leaves. Double-row motor rollers can better adapt to these changes because the two rows of motor rollers can disperse and flatten the tobacco blocks respectively. Through the joint action of two rows of electric rollers, thicker tobacco blocks can be partially unfolded and dispersed by the first row of electric rollers, and then further refined by the second row of electric rollers, ensuring that even thicker tobacco blocks can be evenly distributed.

[0250] In terms of evenly sharing the load, in a single-row electric roller system, if the volume of the tobacco blocks is large or the thickness is high, a single row of electric rollers will have difficulty effectively handling these tobacco blocks due to excessive load. In this case, the single-row electric roller is prone to overload, causing the single-row electric roller to slow down, the single-row electric roller to increase surface wear, and may even cause system failure. The double-row electric rollers effectively share the load. The first row of electric rollers undertakes the task of initial dispersion, reducing the density of the tobacco blocks; the second row of electric rollers further handles the already dispersed tobacco blocks. This load-sharing mechanism reduces the pressure on each row of electric rollers to handle the entire tobacco block load individually, thereby reducing the risk of overload.

[0251] From the production rhythm of the tobacco block packaging production line, if a single row of electric rollers slows down the processing speed due to overload, the rhythm of the entire tobacco leaf packaging production line will be disrupted, resulting in increased waiting time for subsequent processes, and ultimately affecting overall production efficiency. The coordinated work of the double row of electric rollers can better maintain the rhythm of the production line. By evenly sharing the load of tobacco blocks, the two rows of electric rollers can process tobacco blocks more stably at the set speed, reducing the problem of unstable rhythm caused by overload of electric rollers. Even when processing larger batches or thicker tobacco blocks, the tobacco leaf packaging production line can still maintain a consistent speed and efficiency.

[0252] Comparatively, the two-row motor roller system has more motor rollers that can participate in the dispersion of tobacco blocks at the same time compared to a single-row motor roller system. The first row of motor rollers is responsible for the initial dispersion of tobacco blocks, spreading out larger or thicker tobacco blocks to reduce the pressure of subsequent processing. The second row of motor rollers further spreads and refines the tobacco blocks evenly to ensure that they are evenly distributed before falling to the next stage. Because there are two rows of motor rollers processing at the same time, the accumulation problem of tobacco blocks in the first row of motor rollers can be further processed and alleviated in the second row of motor rollers. The coordinated effect of the two rows of motor rollers ensures that the tobacco blocks will not accumulate due to concentration on a certain roller, but will be evenly spread out through dispersion processing.

[0253] When the amount of tobacco blocks is large or the thickness is high, the two rows of motorized rollers can reduce the pressure on each motorized roller by processing different parts of the tobacco blocks separately. In this way, the risk of overloading the motorized roller is reduced, the system runs more smoothly, and the blockage problem caused by excessive load on the motorized roller is avoided. By effectively reducing the risk of accumulation and blockage of tobacco blocks, the two rows of motorized rollers can significantly improve the reliability of the production line. The tobacco blocks can pass through the rollers more smoothly, and production will not be interrupted due to local accumulation or blockage, thereby ensuring stable production efficiency and output.

[0254] Furthermore, both the electric roller and the electric roller with a brush can be used in the layered pre-pressing and packaging integrated machine described in the present invention. Specifically, the electric roller mainly conveys the tobacco blocks by rolling to ensure that the tobacco blocks move at a set speed and direction; the electric roller is used to process relatively neat and uniform tobacco blocks, or in the case where no further refinement is required during the tobacco block homogenization process; the electric roller mainly plays the role of smooth transmission and preliminary homogenization of tobacco block materials, ensuring that the tobacco blocks can pass through the conveying system evenly and be transferred to the next process. Specifically, in addition to conveying tobacco blocks, the brush roller can also spread and disperse the surface of the tobacco blocks through the bristles to prevent the tobacco blocks from piling up or sticking on the brush roller; the brush roller can better adapt to tobacco blocks with irregular shapes and uneven thicknesses; the electric roller with a brush has a better spreading effect on tobacco block materials, especially when the tobacco blocks are piled up higher or thicker, the electric roller with a brush can help spread the tobacco blocks to prevent uneven accumulation, thereby ensuring the uniformity of the tobacco blocks before entering the next process.

[0255] Example 9 Application of the electric roller material distribution unit group 8 in the cigarette block packaging production line

[0256] In a specific embodiment, the specific operation process of the electric roller material distribution section group 8 in the tobacco block packaging production line shows that the coordinated work of the electric brush roller, the transmission system, the adjustment device, the support frame and the electrical control system can achieve uniform distribution of the tobacco blocks, thereby ensuring the smooth progress of the subsequent pre-pressing and packaging processes. Through the electric roller material distribution section group 8 in this embodiment, the production line can achieve uniform distribution of the tobacco blocks, thereby ensuring the smooth progress of the subsequent pre-pressing and packaging processes. The precise coordination of the electric brush roller, the transmission system, the adjustment device, the support frame and the electrical control system ensures that the tobacco leaves have been fully homogenized before entering the reciprocating belt conveyor section group 9, significantly improving the overall quality and production efficiency of tobacco block packaging. At the same time, the two rows of electric brush rollers effectively reduce the risks of accumulation and blockage by processing the tobacco blocks in steps, ensuring the stable operation of the tobacco block packaging production line.

[0257] The structural configuration of the electric roller material distribution unit group 8 is as follows: the electric brush roller is a long cylindrical structure, the surface of which is covered with brushes or rubber coatings, and is installed below the discharge port of the tobacco conveyor 7; the electric brush roller evenly spreads the tobacco leaves through a rotating action to ensure that the tobacco blocks are evenly distributed before falling into the reciprocating belt conveyor unit group 9. The transmission system is driven by an electric motor, and the power is transmitted to the drive shaft of the electric brush roller through a chain or a belt; the transmission system ensures that each electric brush roller can rotate synchronously to complete the uniform distribution of the tobacco blocks at a set speed. The adjustment device is installed on both sides or the bottom of the electric brush roller to adjust the height and angle of the electric brush roller; the adjustment device can accurately adjust the position of the electric brush roller through mechanisms such as bolts or hydraulic cylinders to adapt to tobacco blocks of different thicknesses and shapes. The support frame is a metal structure, which is installed inside the box of the pre-pressing machine unit group 2 and located above the reciprocating belt conveyor unit group 9; the support frame is used to fix the electric brush roller and its transmission system to ensure the stability of the electric roller material distribution unit group 8 during operation. The electrical control system is installed in the control cabinet and connected to the electric brush roller through a cable; the electrical control system is responsible for controlling the rotation speed and operating state of the electric brush roller to ensure that the tobacco blocks are evenly distributed before entering the reciprocating belt conveyor group 9.

[0258] The electric roller material distribution unit 8 is installed below the discharge port of the tobacco conveyor 7 and is directly connected to the reciprocating belt conveyor unit 9. The electrical control system is connected to the control systems of the tobacco conveyor 7, the reciprocating belt conveyor unit 9 and other related equipment to ensure the synchronous operation of the entire tobacco block packaging production line.

[0259] The operation process of the electric roller material distribution unit 8 is as follows:

[0260] S1. Initial uniform distribution: When the tobacco block falls from the outlet of the tobacco conveyor 7, the first row of electric brush rollers immediately starts to rotate; the tobacco block is initially spread and dispersed by the brushes or rubber coating on the surface of the brush rollers. The initial uniform distribution is mainly to prevent the tobacco block from piling up on the conveyor belt and ensure that the tobacco block can be evenly distributed on the conveying path of the first row of brush rollers;

[0261] S2. Further refinement and uniformity: After the initial dispersion of the tobacco blocks by the first row of electric brush rollers, the tobacco blocks then enter the processing area of ​​the second row of electric brush rollers; the second row of electric brush rollers continue to rotate, and through a more detailed flattening effect, the initially dispersed tobacco blocks are further spread out to ensure that the tobacco blocks are evenly distributed over the entire width before falling into the reciprocating belt conveyor unit 9;

[0262] S3. Real-time monitoring and automatic adjustment: The sensor system monitors the flow and distribution of the tobacco blocks in real time, and feeds back the data to the electrical control system; when the sensor system detects uneven distribution or accumulation of tobacco blocks, the control system will automatically adjust the speed and angle of the electric brush roller to ensure uniform distribution of tobacco blocks; the precise control of the adjustment device ensures that even when the thickness or humidity of the tobacco blocks changes, the electric roller material distribution group 8 can still achieve an ideal material distribution effect.

[0263] S4. The tobacco leaves are evenly transported to the next process: After being processed by two rows of electric brush rollers, the tobacco blocks fall evenly into the reciprocating belt conveyor group 9 and are stably transported to the next process - the pre-pressing machine group 2; through the meticulous processing of the electric brush rollers, the tobacco blocks have been fully homogenized before entering the pre-pressing machine group 2, ensuring the smooth progress of the subsequent compression and packaging processes.

[0264] In the entire tobacco packing production line, the electric roller material distribution group 8 works closely with the tobacco conveyor 7 and the reciprocating belt conveyor group 9, so that the tobacco blocks are evenly distributed during the entire conveying process, avoiding the occurrence of accumulation or blockage. This uniform distribution is crucial for the subsequent pre-pressing and packaging processes. The support frame provides reliable structural support for the electric roller material distribution group 8, ensuring that the entire tobacco packing production line can still maintain stable operation under high load conditions, thereby improving the overall efficiency of the tobacco packing production line.

[0265] All operations of the electric roller material distribution unit 8 are managed by the electrical control system. The electrical control system accurately controls the start, stop and rotation speed of the electric brush roller according to production requirements to ensure that the uniform distribution of the tobacco blocks is consistent with the working rhythm of the entire tobacco block packaging production line. By linking with the control systems of other equipment, the electrical control system can automatically adjust the operating parameters of the electric brush roller to cope with different batches and thicknesses of tobacco blocks, ensuring the smooth operation of the tobacco block packaging production line.

[0273] S3. Switch to independent control mode: When processing different types or batches of tobacco leaves, you can switch to independent control mode; the electric roller material distribution unit group 8 allows the two rows of electric brush rollers to be adjusted independently; the front row of electric brush rollers can be rotated at a higher speed, and the rear row of electric brush rollers can be rotated at a lower speed, so as to achieve different material distribution effects;

[0274] S4. Real-time monitoring and feedback adjustment: The sensor continuously monitors the distribution of tobacco leaves and feeds back the data to the control system; if the electric roller material distribution unit 8 detects that the tobacco leaves are unevenly distributed, the electric roller material distribution unit 8 will automatically adjust the speed and direction of the electric roller to ensure that the tobacco leaves are evenly spread on the reciprocating belt conveyor 9;

[0275] S5. Completion of the tobacco block leveling process: After being leveled by the electric roller leveling arrangement section 8, the tobacco blocks are evenly laid on the reciprocating belt conveyor 9 and transported to the pre-pressing and packaging section 2 for further processing.

[0276] In a specific embodiment, the electric roller material distribution group 8 of the layered pre-pressing packaging machine can quickly and evenly distribute the tobacco leaves on the reciprocating belt conveyor 7 through the synchronous rotation mode, avoiding accumulation. The independent control mode of the electric roller material distribution group 8 allows the rotation of the electric roller to be precisely adjusted according to different working conditions to achieve the best material distribution effect.
