Description

Technical Field

[0001] This utility model relates to the technical field of tobacco leaf-beating equipment, and in particular to a high-efficiency multi-roller leaf-beating machine. Background Technology

[0002] In the initial processing of cigarettes, the leaf-beating process mainly involves beating small-sized tobacco leaves with stems to facilitate the subsequent separation of tobacco leaves from stems. The leaf-beating efficiency is related not only to the leaf tearing rate but also to the tobacco leaf breakage rate. Therefore, the leaf-beating process is an essential and important step in the re-drying process.

[0003] The existing leaf threshing machine structure is generally as follows: the main body is a rectangular cavity with open bottom and top. A curved cavity with a rounded transition is connected to the side wall near the bottom of the rectangular cavity. Inside the rectangular cavity above the curved cavity, a fixed leaf threshing roller with a fixed blade and a movable leaf threshing roller that drives the blade are arranged side-by-side. A screen is placed inside the rectangular cavity near the curved cavity. The fixed leaf threshing roller with the fixed blade and the movable leaf threshing roller that drives the blade are located above the screen, forming the most basic structure of the leaf threshing machine. Although this structure can thresh tobacco leaves, it still has the following drawbacks during use:

[0004] (1) The length of the existing leaf-beating machine not only limits the length of the beating roller, but also indirectly limits the number of beating blades. In order to ensure the leaf-beating efficiency and the cleanliness rate, multiple sets of leaf-beating machines can only be set up or the leaves can be beaten again after repeated air separation. In addition, the material distribution equipment needs to be added. As a result, multiple leaf-beating machines not only occupy most of the factory space, but also, due to repeated air separation and leaf beating, the physical properties of tobacco leaves deviate from the optimal moisture content and temperature, which increases the breakage rate or the obtained stems cannot meet the physical properties of the stems for subsequent processing, thus leading to a decrease in the yield of actual products.

[0005] (2) Existing leaf-beating machines have relatively simple processing and adjustment methods for various leaf types. Without adjusting the internal structure of the equipment such as the blade frame distance, blade density, and frame opening size, the only way to control the speed of the leaf-beating roller is to adjust the speed of the leaf-beating roller. When small tobacco leaf pieces are required, increasing the speed of the leaf-beating roller can increase the number of cuts to a certain extent. However, at the same time, the tendency of the roller to throw the material downwards also increases, so the increase in the number of cuts is still limited. Therefore, the leaf-beating efficiency cannot be significantly improved.

[0006] (3) When adjusting the leaf tearing efficiency of the leaf tearing machine, if the leaf tearing efficiency is improved by adjusting the blade frame distance, blade density and frame opening size, it will not only increase the manufacturing cost, but also reduce the practicality of the existing leaf tearing machine, because these adjustments are based on the need to change the structure of the leaf tearing machine, and cannot be adjusted in real time. The machine must be stopped for adjustment.

[0007] (4) It has now entered a bottleneck area. After achieving a balance between the breakage rate and the leaf tearing rate, the leaf tearing rate of the existing leaf-breaking machine can no longer be improved. This is because the leaf-breaking inside the leaf-breaking machine mainly relies on the moving blades on the leaf-breaking roller. Only when the moving blades on the leaf-breaking roller rotate once can they be misaligned with the corresponding fixed blades on the leaf-breaking fixed roller to tear the leaf once. In addition, there are many ineffective rotation intervals between the fixed blades and the moving blades, resulting in the low leaf-breaking efficiency of the existing leaf-breaking machine.

[0008] Therefore, it is necessary to improve and redesign the existing leaf threshing machine structure to solve the problems of low leaf tearing rate and limited processing adjustment methods when processing different types of tobacco leaves. Utility Model Content

[0009] The purpose of this invention is to propose a high-efficiency multi-roller leaf threshing machine to solve the problems of low leaf tearing rate and limited processing adjustment methods when processing different types of tobacco leaves in existing tobacco leaf threshing machines.

[0010] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0011] A high-efficiency multi-roller leaf threshing machine includes a leaf threshing box shell, a first leaf threshing roller, a second leaf threshing roller, a first drive assembly, and a second drive assembly. The three-dimensional leaf threshing box shell has a tobacco leaf inlet, a leaf threshing cavity, and a tobacco leaf outlet, which are interconnected from top to bottom. The first leaf threshing roller and the second leaf threshing roller are both located in the leaf threshing cavity and are staggered on the same horizontal line. The blades on adjacent first leaf threshing rollers are staggered with the blades on adjacent second leaf threshing rollers. The rotating shafts of the first leaf threshing rollers and the second leaf threshing rollers are rotatably connected to the leaf threshing box shell. The first drive assembly is connected to multiple first leaf threshing rollers to drive multiple first leaf threshing rollers to rotate in the leaf threshing cavity. The second drive assembly is connected to multiple second leaf threshing rollers to drive multiple second leaf threshing rollers to rotate in the leaf threshing cavity. The multiple first leaf threshing rollers and the multiple second leaf threshing rollers are located directly above the tobacco leaf outlet.

[0012] Furthermore, the first drive assembly includes a first drive source and a first transmission component; the first drive source is a first frequency-modulated motor, which is connected to a plurality of first leaf-beating rollers via the first transmission component.

[0013] Furthermore, the first transmission component includes a first driving pulley, a first driving conveyor belt, a first driven pulley, and a first driven conveyor belt; a first driving pulley is sleeved on the shaft of the first frequency-modulated motor, and the first driving pulley is connected to the first driven pulley sleeved on one of the first leaf-beating roller shafts via the first driving conveyor belt. The first driven pulleys sleeved on each of the first leaf-beating roller shafts are connected to each other via the first driven conveyor belts. The multiple first leaf-beating roller shafts are rotatably connected to the leaf-beating box shell respectively.

[0014] Furthermore, the second drive assembly includes a second drive source and a second transmission component; the second drive source is a second frequency-modulated motor, which is connected to multiple second leaf-beating rollers via the second transmission component.

[0015] Furthermore, the second transmission component includes a second driving pulley, a second driving conveyor belt, a second driven pulley, and a second driven conveyor belt; a second driving pulley is sleeved on the shaft of the second frequency-modulated motor, and the second driving pulley is connected to the second driven pulley sleeved on one of the shafts of the second leaf-beating rollers via the second driving conveyor belt. The second driven pulleys sleeved on each shaft of the second leaf-beating rollers are connected to each other via the second driven conveyor belt. The multiple shafts of the second leaf-beating rollers are rotatably connected to the leaf-beating box shell respectively.

[0016] Furthermore, rectangular openings are provided on both sides of the blade-beating box shell near the blade-beating cavity, and the rectangular openings are movably connected to the maintenance door through an automatic opening and closing mechanism.

[0017] Furthermore, the automatic opening and closing mechanism includes a connecting web, a cylinder, and a drive seat; the connecting web is connected to the outer wall of the leaf-blowing box shell near the rectangular opening, the ends of the two connecting webs are hinged to the arc-shaped rotating strip connected to the outer wall of the maintenance door, the drive seat connected to the top side wall of the maintenance door is hinged to the drive end of the cylinder, and the fixed ends of the two cylinders are rotatably connected to the connecting seat connected to the outer wall of the leaf-blowing box shell.

[0018] Furthermore, the outer wall of the blade-beating box shell near the rectangular opening has extended wing edges, and multiple bearing seats are respectively provided on the two extended wing edges. The two ends of the first blade-beating roller shaft are rotatably connected to the symmetrically arranged bearing seats, and the two ends of the second blade-beating roller shaft are rotatably connected to another symmetrically arranged bearing seat.

[0019] Furthermore, a first clearance semicircular through groove is provided at the bottom of the inspection door. The first clearance semicircular through groove and the second clearance semicircular through groove provided on the rectangular open side wall are combined to form a clearance circular through groove for the rotational connection of the first leaf roller shaft or the second leaf roller shaft. The clearance circular through groove is on the same horizontal line as the axis of the bearing seat.

[0020] Furthermore, the outer wall of the inspection door is also provided with a first pressing buckle. The snap hook in the first pressing buckle passes through the rectangular groove at the top of the inspection door and snaps into the first U-shaped snap groove. The first U-shaped snap groove is provided on the outer wall of the blade box shell near the rectangular opening.

[0021] Furthermore, a frame with arc-shaped transitions at both ends is provided inside the threshing box shell near the tobacco leaf discharge port. The frame is located directly below the first and second threshing rollers and directly above the tobacco leaf discharge port.

[0022] Furthermore, one end of the end wall of the leaf-beating box shell near the frame is hinged to the leaf-beating box shell, and the second U-shaped fastening groove at the other end of the end wall of the leaf-beating box shell is fastened to the hook in the second pressing buckle on the outer wall of the leaf-beating box shell near the tobacco leaf outlet. The two side walls of the frame can be connected to the inner wall of the leaf-beating box shell where the second pressing buckle is set.

[0023] During operation, when the tobacco leaves are threshed by the leaf threshing machine, the first drive assembly and the second drive assembly can be activated. The first drive assembly drives multiple first leaf threshing rollers to rotate clockwise or counterclockwise within the leaf threshing cavity, and the second drive assembly drives multiple second leaf threshing rollers to rotate clockwise or counterclockwise within the leaf threshing cavity at a suitable speed. When the multiple first leaf threshing rollers rotate clockwise or counterclockwise within the leaf threshing cavity, and when the second drive assembly drives multiple second leaf threshing rollers to rotate clockwise or counterclockwise within the leaf threshing cavity at a suitable speed, a cutting zone for the tobacco leaves is formed between adjacent first and second leaf threshing rollers. Under the influence of the speed difference between adjacent first and second leaf threshing rollers, the tobacco leaves entering this cutting zone can be torn multiple times with each rotation of the first and second leaf threshing rollers, indirectly improving the leaf threshing efficiency. Then, the cut and threshed tobacco leaves fall through the tobacco leaf discharge port into the subsequent tobacco processing steps for further processing.

[0024] During the threshing process of tobacco leaves, if it is necessary to ensure that the cut tobacco leaves have a certain size, the first drive assembly drives the first threshing roller to rotate clockwise at a suitable speed within the threshing cavity, and the second drive assembly drives the second threshing roller to rotate counterclockwise at a suitable speed within the threshing cavity; or, the first drive assembly drives the first threshing roller to rotate counterclockwise at a suitable speed within the threshing cavity, and the second drive assembly drives the second threshing roller to rotate clockwise at a suitable speed within the threshing cavity. In this way, adjacent first and second threshing rollers rotate in opposite directions, and the tobacco leaves fall... When cutting in the cutting zone between the first and second leaf-beating rollers that rotate in opposite directions, on the one hand, there is a speed difference between the first and second leaf-beating rollers moving up and down, and on the other hand, the upward cutting of the first and second leaf-beating rollers is not obvious. The tobacco leaf cutting surface formed between the first and second leaf-beating rollers is not only reduced by half, but the reverse rotation of the first and second leaf-beating rollers also improves the downward throwing effect of the tobacco leaf, avoiding the situation of excessive leaf beating. In this way, the tobacco leaves produced have a certain degree of largeness.

[0025] During the tobacco threshing process, if there is insufficient material entering the threshing machine or the threshed leaves are too large, the first drive assembly drives the first threshing roller to rotate clockwise at a suitable speed within the threshing cavity, and the second drive assembly drives the second threshing roller to rotate clockwise at a suitable speed within the threshing cavity; or, the first drive assembly drives the first threshing roller to rotate counterclockwise at a suitable speed within the threshing cavity, and the second drive assembly drives the second threshing roller to rotate counterclockwise at a suitable speed within the threshing cavity. In this way, adjacent first and second threshing rollers rotate in the same direction. When the tobacco leaves fall into the cutting area between the co-rotating first and second threshing rollers, there is a certain amount of upward and downward material throwing between them simultaneously. With the mutual cancellation of the effects of the throwing and downward throwing, coupled with the movement trends of the first and second beating rollers and the factor of gravity, the tobacco leaves passing through the cutting zone between the first and second beating rollers are cut multiple times per unit time, thus reducing the size of the beating leaves. During this beating process, if the first and second beating rollers rotating in the same direction have the maximum speed and the most cuts, the speed of the first drive component or the second drive component is reduced. This reduces the speed of the first beating roller connected to the first drive component or the second beating roller connected to the second drive component, so that the tobacco leaves passing between the first and second beating rollers rotating in the same direction reach a moderate number of cuts to meet the processing requirements of different processes.

[0026] During the tobacco threshing process, if the amount of tobacco leaves distributed near the two inner walls of the threshing machine is less and the amount of tobacco leaves distributed in the middle of the threshing machine is more, the pulleys fitted to the first and second threshing roller shafts near the two inner walls of the threshing machine should be enlarged, while the pulleys fitted to the first and second threshing roller shafts near the middle of the threshing machine should be enlarged. In this way, by changing the size of the pulleys, the rotation speed of the threshing rollers in different parts can be appropriately adjusted. This not only rationally configures the rotation speed of the first and second threshing rollers, but also further improves the overall uniformity of threshing.

[0027] Compared with the prior art, the present invention has at least one of the following beneficial effects:

[0028] 1. This utility model provides a first leaf-beating roller and a second leaf-beating roller, both driven by a first driving component, within the leaf-beating cavity of the leaf-beating box shell. The first and second leaf-beating rollers are staggered on the same horizontal line, and the blades on adjacent first and second leaf-beating rollers are also staggered. This allows adjacent first and second leaf-beating rollers to rotate relative to each other during leaf-beating, forming a cutting zone between them. The tobacco leaves entering this cutting zone are torn multiple times per rotation of the first and second leaf-beating rollers due to the speed difference between them, significantly improving the cutting efficiency and solving the problem of low leaf-beating and tearing rates in existing tobacco leaf-beating machines.

[0029] 2. This utility model provides a first leaf-beating roller and a second leaf-beating roller, both driven by a first driving component, within the leaf-beating cavity of the leaf-beating box shell. The first and second leaf-beating rollers are staggered on the same horizontal line, and the blades on adjacent first and second leaf-beating rollers are staggered. In other words, the traditional leaf-beating machine method of moving blades cooperating with fixed blades to beat tobacco leaves is replaced by the method in this application where the blades on the first and second leaf-beating rollers move relative to each other to cut and beat the tobacco leaves, indirectly reducing the probability of jamming of the first and second leaf-beating rollers.

[0030] 3. This utility model, by providing a first leaf-beating roller and a second leaf-beating roller driven by a first driving component in the leaf-beating cavity of the leaf-beating box shell, with the first and second leaf-beating rollers staggered on the same horizontal line and the blades on adjacent first and second leaf-beating rollers staggered, can adapt to different processing requirements or different processing conditions. The first driving component controls the first leaf-beating roller to rotate clockwise or counterclockwise at a certain speed, and the second driving component controls the second leaf-beating roller to rotate clockwise or counterclockwise at a suitable speed. This creates a cutting zone for the tobacco leaves between the first and second leaf-beating rollers rotating at suitable speeds. The tobacco leaves entering this cutting zone are then broken into blades of different specifications to meet the processing requirements of different processes, thus making the processing adjustment methods more flexible when processing different tobacco leaves.

[0031] 4. By setting the body of the leaf-beating machine as a three-dimensional box structure, the space occupied by the three-dimensional box structure in the re-drying workshop is not only reduced, but the regular three-dimensional box structure is also easy to transport.

[0032] 5. This utility model provides rectangular openings on both sides of the blade box shell near the blade-beating cavity. The rectangular openings are movably connected to the maintenance door through an automatic opening and closing mechanism. When it is necessary to maintain or repair the first and second blade-beating rollers in the blade-beating cavity, the maintenance door covering the rectangular openings can be automatically opened through the automatic opening and closing mechanism, so that maintenance personnel can perform maintenance or repair on the first and second blade-beating rollers in the blade-beating cavity.

[0033] 6. This utility model features a partial leaf-beating box shell with one end hinged to the leaf-beating box shell near the frame, and a second U-shaped fastening groove at the other end of the partial leaf-beating box shell engaging with a hook in the second pressing buckle on the outer wall of the leaf-beating box shell near the tobacco leaf discharge port. When the operator needs to observe the material falling on the frame, the hook in the second pressing buckle can be separated from the second U-shaped fastening groove, and then the end wall of the partial leaf-beating box shell can be pulled open, making the frame visible to the operator, who can then observe the material falling on the frame.

Detailed Implementation

[0053] like Figure 1-18 As shown, to make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0054] Example

[0055] The existing leaf threshing machine structure is generally as follows: the main body of the machine is a rectangular cavity with open bottom and top. A curved cavity with a rounded transition is connected to the side wall near the bottom of the rectangular cavity. Inside the rectangular cavity above the curved cavity, a fixed leaf threshing roller with a fixed blade and a moving leaf threshing roller that drives the blade are arranged side by side. A screen is set in the rectangular cavity near the curved cavity. The fixed leaf threshing roller with the fixed blade and the moving leaf threshing roller that drives the blade are located above the screen, which constitutes the most basic structure of the leaf threshing machine. Although the leaf threshing machine with this structure can thresh tobacco leaves, it still has the defects of low leaf tearing rate and limited processing adjustment methods when processing different types of tobacco leaves.

[0056] Therefore, this application proposes a high-efficiency multi-roller leaf threshing machine to solve the problems of low leaf tearing rate and limited processing adjustment methods when processing different types of tobacco leaves in existing tobacco leaf threshing machines.

[0057] For details, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A high-efficiency multi-roller leaf threshing machine includes a leaf threshing box shell 1, a first leaf threshing roller 5, a second leaf threshing roller 6, a first drive assembly 7, and a second drive assembly 8. The three-dimensional leaf threshing box shell 1 has a tobacco leaf inlet 2, a leaf threshing cavity 3, and a tobacco leaf outlet 4, which are interconnected from top to bottom. The first leaf threshing roller 5 and the second leaf threshing roller 6 are both located in the leaf threshing cavity 3, and are staggered on the same horizontal line. The blades on the first leaf-beating roller 5 and the blades on the second leaf-beating roller 6 are arranged alternately. The rotating shafts of the first leaf-beating roller 5 and the second leaf-beating roller 6 are rotatably connected to the leaf-beating box shell 1, respectively. The first drive assembly 7 is connected to multiple first leaf-beating rollers 5 to drive multiple first leaf-beating rollers 5 to rotate in the leaf-beating cavity 3. The second drive assembly 8 is connected to multiple second leaf-beating rollers 6 to drive multiple second leaf-beating rollers 6 to rotate in the leaf-beating cavity 3. The multiple first leaf-beating rollers 5 and multiple second leaf-beating rollers 6 are located directly above the tobacco leaf discharge port 4.

[0058] In practical applications, when using a leaf threshing machine to thresh tobacco leaves, the first drive assembly 7 and the second drive assembly 8 can be activated. The first drive assembly 7 drives multiple first threshing rollers 5 to rotate clockwise or counterclockwise at a suitable speed within the threshing cavity 3, and the second drive assembly 8 drives multiple second threshing rollers 6 to rotate clockwise or counterclockwise at a suitable speed within the threshing cavity 3. When the tobacco leaves are rotated clockwise or counterclockwise at a suitable speed in the leaf-beating cavity 3, a cutting zone for the tobacco leaves is formed between the adjacent first leaf-beating roller 5 and second leaf-beating roller 6. Under the influence of the speed difference between the adjacent first leaf-beating roller 5 and second leaf-beating roller 6, the tobacco leaves entering the cutting zone can be torn multiple times for each rotation of the first leaf-beating roller 5 and second leaf-beating roller 6, which indirectly improves the leaf-beating efficiency. Then, the cut and beaten tobacco leaves fall through the tobacco leaf outlet into the subsequent tobacco leaf processing process for further processing.

[0059] During the tobacco threshing process, if it is necessary to ensure that the cut tobacco leaves have a certain size, the first drive assembly 7 drives the first threshing roller 5 to rotate clockwise at a suitable speed within the threshing cavity 3, and the second drive assembly 8 drives the second threshing roller 6 to rotate counterclockwise at a suitable speed within the threshing cavity 3; or, the first drive assembly 7 drives the first threshing roller 5 to rotate counterclockwise at a suitable speed within the threshing cavity 3, and the second drive assembly 8 drives the second threshing roller 6 to rotate clockwise at a suitable speed within the threshing cavity 3. In this way, adjacent first threshing rollers 5 and second threshing rollers 6 rotate in opposite directions. When the tobacco leaves fall into the cutting zone between the first and second leaf-beating rollers 5 and 6, which rotate in opposite directions, the cutting surface of the tobacco leaves formed between them is reduced by half. Furthermore, the opposite rotation of the first and second leaf-beating rollers 5 and 6 improves the downward throwing effect of the tobacco leaves, thus avoiding excessive leaf beating. In this way, the tobacco leaves produced have a certain degree of largeness.

[0060] During the tobacco threshing process, if there is insufficient material entering the threshing machine or the threshed leaves are too large, the first drive assembly 7 drives the first threshing roller 5 to rotate clockwise at a suitable speed within the threshing cavity 3, and the second drive assembly 8 drives the second threshing roller 6 to rotate clockwise at a suitable speed within the threshing cavity 3. Alternatively, the first drive assembly 7 drives the first threshing roller 5 to rotate counterclockwise at a suitable speed within the threshing cavity, and the second drive assembly 8 drives the second threshing roller 6 to rotate counterclockwise at a suitable speed within the threshing cavity 3. In this way, adjacent first threshing rollers 5 and second threshing rollers 6 rotate in the same direction. When the tobacco leaves fall into the cutting area between the co-rotating first threshing rollers 5 and second threshing rollers 6, there is a certain amount of upward and downward material throwing between them simultaneously. With some of the effects offset by each other, and considering the movement trends of the first and second beating rollers 5 and 6, as well as gravity, the tobacco leaves passing through the cutting zone between the first and second beating rollers 5 and 6 are cut multiple times per unit time. This results in a smaller size of the finished leaves. During this beating process, if the first and second beating rollers 5 and 6, rotating in the same direction, reach their maximum speed and make the most cuts, the speed of the first drive assembly 7 or the second drive assembly 8 is reduced. This reduces the speed of the first beating roller 5 connected to the first drive assembly 7 or the second beating roller 6 connected to the second drive assembly 8, ensuring that the tobacco leaves passing between the first and second beating rollers 5 and 6, rotating in the same direction, achieve a suitable number of cuts. This allows for the production of tobacco leaves that meet the processing requirements of different processes, making the processing adjustment methods less singular when processing different types of tobacco leaves.

[0061] Please see Figure 6 and Figure 2 The first drive assembly 7, which is used to drive multiple first leaf-beating rollers 5 to rotate clockwise or counterclockwise at a suitable speed in the leaf-beating cavity 3, includes a first drive source and a first transmission component 9; wherein, the first drive source is used to drive the first transmission component 9 to perform transmission; the first transmission component 9 is used to drive multiple first leaf-beating rollers 5 in the leaf-beating cavity 3 to rotate clockwise or counterclockwise at a certain speed.

[0062] Specifically, the first driving source is a first frequency-modulated motor 10, which is connected to multiple first leaf-beating rollers 5 via a first transmission component 9.

[0063] In practical applications, when the first drive assembly 7 drives multiple first leaf-beating rollers 5 to rotate clockwise or counterclockwise at a certain speed, the first speed-regulating motor 10 rotates in the forward direction. The output shaft of the first frequency-regulating motor 10, which rotates in the forward direction, drives multiple first leaf-beating rollers 5, which are connected to the first transmission component 9, to rotate clockwise at a suitable speed through the first transmission component 9.

[0064] When the first drive assembly 7 drives multiple first leaf-beating rollers 5 to rotate counterclockwise at a suitable speed, it causes the first speed-regulating motor 10 to rotate in the opposite direction. The output shaft of the first frequency-regulating motor 10, which rotates in the opposite direction, drives multiple first leaf-beating rollers 5, which are connected to the first transmission component 9, to rotate counterclockwise at a suitable speed through the first transmission component 9.

[0065] It should be noted that the first frequency-modulated motor 10 is a speed-adjustable motor. Frequency-modulated motors are existing technology, and no improvements or explanations have been made to them. Therefore, their structure will not be described in detail. The second frequency-modulated motor 10 is located outside the blade box housing 1.

[0066] Please see Figure 6 and Figure 8 The first transmission component 9, used to realize the transmission connection between multiple first leaf-beating rollers 5, includes a first driving pulley 11, a first driving conveyor belt 12, a first driven pulley 13, and a first driven conveyor belt 28. The first driving pulley 11 is used to transmit the rotation of the first speed-regulating motor 10 to the first driven pulley 13 sleeved on the shaft of one of the first leaf-beating rollers 5 through the first driving conveyor belt 12. The first driven conveyor belt 28 is used to transmit the rotation of the first driven pulley 13 sleeved on the shaft of one of the first leaf-beating rollers 5 to another first driven pulley 13 sleeved on the shaft of another first leaf-beating roller 5 through other first driven conveyor belts 28, so as to realize the rotation process of multiple first leaf-beating rollers 5 rotating clockwise or counterclockwise at a suitable speed.

[0067] Specifically, a first drive pulley 11 is sleeved on the shaft of the first frequency-modulated motor 10. The first drive pulley 11 is connected to the first driven pulley 13 sleeved on the shaft of one of the first leaf-beating rollers 5 via the first drive conveyor belt 12. The first driven pulleys 13 sleeved on the shaft of each first leaf-beating roller 5 are connected to each other via the first driven conveyor belt 28. The shafts of multiple first leaf-beating rollers 5 are rotatably connected to the leaf-beating box shell 1 respectively.

[0068] In practical application, when the first transmission component 9 drives multiple first leaf-beating rollers 5 to rotate clockwise at a suitable speed, the first speed-regulating motor 10 first drives the first drive pulley 11 to rotate clockwise. The clockwise rotating first drive pulley 11 then drives the first driven pulley 13 sleeved on the shaft of one of the first leaf-beating rollers 5 to rotate through the first drive conveyor belt 12. Then, the first driven pulley 13 on the shaft of one of the first leaf-beating rollers 5 transmits the rotation to the first driven pulleys 13 on the shafts of other first driven conveyor belts 28 in sequence. In this way, multiple first leaf-beating rollers 5 rotate clockwise at a suitable speed in the leaf-beating cavity 3 under the transmission drive of the first transmission component 9.

[0069] When the first transmission component 9 drives multiple first leaf-beating rollers 5 to rotate counterclockwise at a suitable speed, the first speed-regulating motor 10 first drives the first drive pulley 11 to rotate counterclockwise. The counterclockwise rotating first drive pulley 11 then drives the first driven pulley 13 sleeved on the shaft of one of the first leaf-beating rollers 5 to rotate through the first drive conveyor belt 12. Then, the first driven pulley 13 on the shaft of one of the first leaf-beating rollers 5 transmits the rotation to the first driven pulleys 13 on the shafts of other first driven conveyor belts 28 in sequence. In this way, multiple first leaf-beating rollers 5 rotate counterclockwise at a suitable speed in the leaf-beating cavity 3 under the transmission drive of the first transmission component 9.

[0070] It should be noted that the specifications of the first driving pulley 11 and the multiple first driven pulleys 13 can be arranged appropriately according to the actual speed regulation conditions.

[0071] Please see Figure 7 and Figure 2 The second drive assembly 8, which is used to drive multiple second leaf-beating rollers to rotate clockwise or counterclockwise at a suitable speed in the leaf-beating cavity 3, includes a second drive source and a second transmission component 14; wherein, the second drive source is used to drive the second transmission component 14 to perform transmission; the second transmission component 14 is used to drive multiple second leaf-beating rollers 6 in the leaf-beating cavity 3 to rotate clockwise or counterclockwise at a suitable speed.

[0072] Specifically, the second drive source is a second frequency-modulated motor 15, which is connected to multiple second leaf-beating rollers 6 via a second transmission component 14.

[0073] In practical applications, when the second drive assembly 8 drives multiple second leaf-beating rollers 6 to rotate clockwise at a suitable speed, the second speed-regulating motor 15 rotates in the forward direction. The output shaft of the clockwise rotating second frequency-regulating motor 15 then drives multiple second leaf-beating rollers 6, which are connected to the second transmission component 14, to rotate clockwise at a suitable speed through the second transmission component 14.

[0074] When the first drive assembly 7 drives multiple first leaf-beating rollers 5 to rotate counterclockwise at a suitable speed, it causes the first speed-regulating motor 10 to rotate in the opposite direction. The output shaft of the first frequency-regulating motor 10, which rotates in the opposite direction, drives multiple first leaf-beating rollers 5, which are connected to the first transmission component 9, to rotate counterclockwise at a suitable speed through the first transmission component 9.

[0075] It should be noted that the second frequency-modulated motor 15 is a speed-adjustable motor. Frequency-modulated motors are existing technology, and no improvements or designs have been made to them. Therefore, their structure will not be described in detail. The second frequency-modulated motor 15 is located outside the blade box housing 1.

[0076] Please see Figure 7 and Figure 8The second transmission component 14, used to realize the transmission connection between multiple second leaf-beating rollers 6, includes a second driving pulley 16, a second driving conveyor belt 17, a second driven pulley 18, and a second driven conveyor belt 19. The second driving pulley 16 is used to transmit the rotation of the second speed-regulating motor 15 to the second driven pulley 18 sleeved on the shaft of one of the second leaf-beating rollers 6 through the second driving conveyor belt 17. The second driven conveyor belt 19 is used to transmit the rotation of the second driven pulley 18 sleeved on the shaft of one of the second leaf-beating rollers 6 to another second driven pulley 18 sleeved on the shaft of another second leaf-beating roller 6 through other second driven conveyor belts 9, so as to realize the rotation process of multiple first leaf-beating rollers 5 rotating in the same or opposite directions at different speeds.

[0077] Specifically, a second drive pulley 16 is sleeved on the shaft of the second frequency-modulated motor 15. The second drive pulley 16 is connected to the second driven pulley 18 sleeved on the shaft of one of the second leaf-beating rollers 6 via the second drive conveyor belt 17. The second driven pulleys 18 sleeved on the shaft of each second leaf-beating roller 6 are connected to each other via the second driven conveyor belt 19. The shafts of multiple second leaf-beating rollers 6 are rotatably connected to the leaf-beating box shell 1 respectively.

[0078] In practical application, when the second transmission component 14 drives multiple second leaf-beating rollers 6 to rotate clockwise at a suitable speed, the second speed-regulating motor 15 first drives the second drive pulley 16 to rotate in the forward direction. The forward-rotating second drive pulley 16 then drives the second driven pulley 18 sleeved on the shaft of one of the second leaf-beating rollers 6 to rotate through the first drive conveyor belt 12. Then, the second driven pulley 18 on the shaft of one of the second leaf-beating rollers 6 transmits the rotation to the second driven pulleys 19 on the shafts of other second driven rollers 6 in sequence through other second driven conveyor belts 17. In this way, multiple second leaf-beating rollers 6 rotate clockwise at a suitable speed in the leaf-beating cavity 3 under the transmission drive of the second transmission component 14.

[0079] When the second transmission component 14 drives multiple second leaf-beating rollers 6 to rotate counterclockwise at a suitable speed, the second speed-regulating motor 15 first drives the second drive pulley 16 to rotate in the opposite direction. The second drive pulley 16 rotating in the opposite direction then drives the second driven pulley 18 sleeved on the shaft of one of the second leaf-beating rollers 6 to rotate through the first drive conveyor belt 12. Then, the second driven pulley 18 on the shaft of one of the second leaf-beating rollers 6 transmits the rotation to the second driven pulleys 19 on the shafts of other second driven conveyor belts 17 in sequence. In this way, multiple second leaf-beating rollers 6 rotate counterclockwise at a suitable speed in the leaf-beating cavity 3 under the transmission drive of the second transmission component 14.

[0080] It should be noted that the specifications of the second driving pulley 16 and the multiple second driven pulleys 18 can be arranged appropriately according to the actual speed regulation conditions.

[0081] Please see Figure 9 and 16 To facilitate maintenance and repair of the first leaf-beating roller 5 and the second leaf-beating roller 6 inside the leaf-beating cavity 3, rectangular openings 20 are provided on the two side walls of the leaf-beating box shell 1 near the leaf-beating cavity 3. The rectangular openings 20 are movably connected to the maintenance door 22 through the automatic opening and closing mechanism 21.

[0082] In practical applications, when maintenance or repair is required on the first leaf-beating roller 5 and the second leaf-beating roller 6 inside the leaf-beating cavity 3, the maintenance door 22 covering the rectangular opening 20 can be automatically opened by the automatic opening and closing mechanism 21, exposing the first leaf-beating roller 5 and the second leaf-beating roller 6 inside the leaf-beating cavity 3 to the field of vision of the maintenance personnel. The maintenance personnel can then perform maintenance or repair on the first leaf-beating roller 5 and the second leaf-beating roller 6 through the rectangular opening 20, which facilitates the maintenance personnel to perform maintenance or repair on the first leaf-beating roller and the second leaf-beating roller inside the leaf-beating cavity, thereby extending the service life of the first leaf-beating roller 5 and the second leaf-beating roller 6.

[0083] Please see Figure 9 and Figure 10 An automatic opening and closing mechanism 21 for automatically opening and closing the inspection door 22 that covers the rectangular opening 20 includes a connecting web 23, a cylinder 24, and a drive seat 25; wherein, the connecting web 23 serves as a medium for connecting the inspection door 22 to the leaf spring housing 1; the cylinder 24 drives the drive seat 25 connected to the top side of the inspection door 22 to realize the process of automatically opening and closing the inspection door.

[0084] Specifically, the connecting webs 23 are respectively connected to the outer wall of the blade box shell 1 near the rectangular opening 20. The ends of the two connecting webs 23 are hinged to the arc-shaped rotating strips 38 connected to the outer wall of the inspection door 22. The drive seat 25 connected to the outer top side wall of the inspection door 22 is hinged to the drive end of the cylinder 24. The fixed ends of the two cylinders 24 are respectively rotatably connected to the connecting seats connected to the outer wall of the blade box shell 1.

[0085] In practical application, when the automatic opening and closing mechanism 21 drives the maintenance door 22 to open automatically, the cylinder 24 extends to drive the drive seat on the maintenance door 22, and the maintenance door 22, which is closed at the rectangular opening 20, separates from the rectangular opening 20. The rectangular opening 20 is then exposed to the view of the maintenance personnel, thus completing the process of the automatic opening and closing mechanism 21 automatically opening the maintenance door 22.

[0086] When the automatic opening and closing mechanism 21 drives the maintenance door 22 to close automatically, the cylinder 24 drives the drive seat on the maintenance door 22 through the retraction action. The maintenance door 22, which is not covered by the rectangular opening 20, flips to the rectangular opening 20 to form a cover. The rectangular opening 20 then disappears from the view of the maintenance personnel, thus completing the process of the automatic opening and closing mechanism 21 closing and opening the maintenance door 22.

[0087] Please see Figure 1 and Figure 3 To facilitate stable support and smoother rotation of the first leaf-beating roller shaft 5 and the second leaf-beating roller 6 shafts, an extended wing 26 is provided on the outer wall of the leaf-beating box shell 1 near the rectangular opening 20. Multiple bearing seats 27 are respectively provided on the two extended wing 26, that is, multiple bearing seats 27 on one side of the extended wing 26 and multiple bearing seats 27 on the other side of the extended wing 26 are arranged symmetrically in sequence. The two ends of the first leaf-beating roller 5 shaft are rotatably connected to the symmetrically arranged bearing seats 27, and the two ends of the second leaf-beating roller 6 shaft are rotatably connected to another symmetrically arranged bearing seat 27.

[0088] In practical applications, during the rotation of the first leaf-beating roller shaft 5 and the second leaf-beating roller 6 shafts within the leaf-beating cavity 3, multiple bearing seats 27 are symmetrically arranged on the extended wing edges 26 on both sides. The two ends of the first leaf-beating roller 5 shaft are rotatably connected to the symmetrically arranged bearing seats 27, and the two ends of the second leaf-beating roller 6 shaft are rotatably connected to another symmetrically arranged bearing seat 27. Therefore, the first leaf-beating roller shaft 5 and the second leaf-beating roller 6 shafts rotate more smoothly.

[0089] It should be noted that the extended wing 26 is a rectangular frame. In order to avoid interference between the extended wing 26 of the rectangular frame and the connecting web, some of the extended wing 26 protrude from the connecting web 23.

[0090] Please see Figure 10 , Figure 11 and Figure 16 To prevent the rotating shafts of the first leaf-beating roller 5 and the second leaf-beating roller 6 from interfering with the inspection door 22 and the side wall of the rectangular opening 20, a first clearance semi-circular through groove 29 is provided at the bottom of the inspection door 22. The first clearance semi-circular through groove 29 and the second clearance semi-circular through groove 30 provided on the side wall of the rectangular opening 20 are combined to form a clearance circular through groove 31 through which the shaft of the first leaf-beating roller 5 or the shaft of the second leaf-beating roller 6 can pass. The clearance circular through groove 31 is on the same horizontal line as the axis of the bearing seat 27.

[0091] In practical application, during the rotation of the first leaf-beating roller shaft 5 and the second leaf-beating roller 6 shaft, since the first clearance semi-circular through groove 29 opened at the bottom of the inspection door 22 and the second clearance semi-circular through groove 30 opened on the side wall of the rectangular opening 20 are combined to form a clearance circular through groove 31 for the rotation connection of the first leaf-beating roller 5 shaft or the second leaf-beating roller 6 shaft, the rotating first leaf-beating roller shaft 5 and the second leaf-beating roller 6 shaft will not interfere with the inspection door 22 and the rectangular opening 20.

[0092] Please see Figure 11 , Figure 12 and Figure 18To improve the sealing between the inspection door 22 and the blade box housing 1, a first pressing buckle 32 is also provided on the outer wall of the inspection door 22. The snap hook in the first pressing buckle 32 passes through the rectangular groove at the top of the inspection door 22 and is movably snapped with the first U-shaped snap groove 33. The first U-shaped snap groove 33 is provided on the outer wall of the blade box housing 1 near the rectangular opening 22.

[0093] In practical application, after the inspection door 22 is closed to the rectangular opening 20 by the cylinder 24, the first pressing buckle 32 on the outer wall of the inspection door 22 can be pressed to make the hook in the first pressing buckle 32 engage with the first U-shaped fastening groove 33 on the outer wall of the blade box shell 1 near the rectangular opening 22, thereby indirectly improving the sealing between the inspection door 22 and the rectangular opening 20 and preventing the blades after being opened from getting stuck between the inspection door 22 and the rectangular opening 20.

[0094] It should be noted that the snap-fit ​​between the first snap buckle 32 and the first U-shaped snap-fit ​​groove 33 is existing technology. No improvements or designs have been made to the first snap buckle 32 and the first U-shaped snap-fit ​​groove 33, so their structure will not be described in detail.

[0095] Please see Figure 13 , Figure 4 and Figure 17 In order to screen the tobacco leaves after they have been beaten by the first beating roller 5 and the second beating roller 6, or to beat some of the larger tobacco leaves again, a frame 34 with arc-shaped transitions at both ends is provided in the beating box shell 1 near the tobacco leaf discharge port 4. The frame 34 is located directly below the first beating roller 5 and the second beating roller 6 and directly above the tobacco leaf discharge port 4.

[0096] In practical application, after the first beating roller 5 and the second beating roller 6 beat the tobacco leaves, some tobacco leaves smaller than the mesh of the frame 34 will fall through the mesh of the frame 34, while other tobacco leaves larger than the mesh of the frame 34 will be picked up again by the rotation of the first beating roller 5 and the second beating roller 6. The blades on the adjacent first beating roller 5 and the second beating roller 6 will continue to cut the large tobacco leaves into qualified tobacco leaves.

[0097] It should be noted that the two ends of the frame 34 are set as arc transitions so that the tobacco leaves after threshing can slide down the two arc transition areas of the frame 34 to the middle of the frame 34.

[0098] Please see Figure 14 , Figure 15 , Figure 17 and Figure 18To facilitate operators' observation or understanding of the material falling on the frame, one end of the end wall 35 of the leaf-beating box shell 1 near the frame 34 is hinged to the leaf-beating box shell 1. The other end of the end wall 35 of the leaf-beating box shell 1 has a second U-shaped fastening groove 36 that is movably fastened to the hook in the second pressing buckle 37 on the outer wall of the leaf-beating box shell 1 near the tobacco leaf discharge port 4. The two side walls of the frame 34 can be connected to the inner wall of the leaf-beating box shell 1 where the second pressing buckle 37 is set. The arc transition sections at both ends of the frame 34 are in contact with the inner wall of the leaf-beating box shell 1 above the end wall 35, that is, the frame 34 is not connected to the end wall 35.

[0099] In practical applications, when it is necessary to observe or understand the situation of the material (large tobacco leaves after beating) falling on the frame 34, first press the second pressing buckle 37 to separate the second pressing buckle 37 on the outer wall of the beating box shell 1 from the second U-shaped fastening groove 36 at the other end of the end wall 35 of part of the beating box shell 1. Then pull open the end wall 35 of part of the beating box shell 1, and the frame 34 will appear in the operator's field of vision, allowing the operator to observe the material falling on the frame 34.

[0100] It should be noted that the snap-fit ​​between the second snap buckle 37 and the second U-shaped snap-fit ​​groove 36 is existing technology. The second snap buckle 37 and the second U-shaped snap-fit ​​groove 36 have not been improved or designed, so their structure will not be described in detail.
