Description

Technical Field

[0001] The invention relates to the technical field of tobacco leaf threshing equipment, in particular to a high-efficiency multi-roller threshing machine. Background Art

[0002] During the primary processing of cigarettes, the main function of the leaf threshing process is to thresh small-sized tobacco leaves with stems, which plays a certain auxiliary role in the subsequent separation of tobacco leaves and stems. Among them, the leaf threshing efficiency in the leaf threshing process is not only related to the leaf tearing rate, but also to the tobacco leaf breakage rate. Therefore, the leaf threshing process is an indispensable and important process in the leaf threshing and re-roasting link.

[0003] The structure of the existing leaf thresher is generally as follows: the main body of the machine is a rectangular cavity with both the bottom and the top open, and the side wall near the bottom of the rectangular cavity is connected to an arc-shaped cavity with a circular arc transition, and a fixed leaf thresher roller with a fixed knife and a dynamic leaf thresher roller with a driving knife are arranged side by side inside the rectangular cavity on one side above the arc-shaped cavity with the circular arc transition, and a screen is arranged in the rectangular cavity near the arc-shaped cavity with the circular arc transition, and the fixed leaf thresher roller with a fixed knife and the dynamic leaf thresher roller with a driving knife are located above the screen, so as to form the most basic structure of the leaf thresher. Although the leaf thresher of this structure can also thresh tobacco leaves, it still has the following defects during use:

[0004] (1) The length of the existing threshing machine not only limits the length of the threshing roller, but also indirectly limits the number of threshing knives. In order to ensure the threshing efficiency and the cleaning rate, multiple threshing machines can only be set up or the leaves can be threshed again after repeated air separation, and the matching material separation equipment needs to be added. In this way, multiple threshing machines not only occupy most of the factory space, but also because of repeated air separation and threshing, the deviation between the physical indicators of tobacco leaves and the optimal moisture content and temperature becomes larger, which increases the crushing rate or the obtained stems cannot meet the physical indicators of the stems for subsequent processing, thereby reducing the actual yield.

[0005] (2) The existing leaf thresher has relatively simple processing and adjustment methods for various leaf shape requirements. Without adjusting the internal structure of the equipment such as the distance between the leaf thresher blades and the density of the blades and the size of the frame opening, there is only one way to control the rotation speed of the leaf thresher roller. Under the working condition that small tobacco leaves are required, the leaf thresher can increase the number of cuts to a certain extent after increasing the rotation speed of the leaf thresher roller. However, at the same time, the tendency of the roller to throw the material downward also increases. The increase in the number of cuts still has certain limitations, so the leaf thresher efficiency cannot be significantly improved.

[0006] (3) When adjusting the leaf tearing efficiency of the leaf thresher, if the leaf tearing efficiency of the leaf thresher is improved by adjusting technical parameters such as the distance between the leaf thresher blades, the density of the blades, and the size of the frame opening, it will not only increase the manufacturing cost but also reduce the practicality of the existing leaf thresher, because these adjustments are based on the need to change the structure of the leaf thresher, and real-time adjustment cannot be achieved, and the machine must be shut down for adjustment.

[0007] (4) At present, it has entered a bottleneck area. After achieving a balance between the crushing rate and the leaf tearing rate, the leaf tearing rate of the existing leaf thresher can no longer be improved. This is because the leaves inside the leaf thresher are mainly threshed by the moving knife on the leaf thresher roller. The moving knife on the leaf thresher roller can only tear the leaves once with the corresponding fixed knife on the leaf thresher roller every time it rotates one circle. In addition, there are many invalid rotation intervals between the fixed knife and the moving knife, resulting in low leaf threshing efficiency of the existing leaf thresher.

[0008] Therefore, it is necessary to improve and design the existing tobacco leaf thresher structure to solve the problems of low leaf threshing rate and single processing adjustment means when processing different required tobacco leaves. Summary of the invention

[0009] The purpose of the present invention is to provide a high-efficiency multi-roller beating machine to solve the problems of low beating and tearing rate of tobacco leaves in existing tobacco beating machines and single processing and adjustment means when processing different required tobacco leaves.

[0010] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0011] A high-efficiency multi-roller leaf beating machine, comprising a leaf beating box shell, a first leaf beating roller, a second leaf beating roller, a first drive assembly and a second drive assembly; the three-dimensional leaf beating box shell has a tobacco leaf feeding port, a leaf beating cavity and a tobacco leaf discharging port, and the tobacco leaf feeding port, the leaf beating cavity and the tobacco leaf discharging port are interconnected from top to bottom; the first leaf beating roller and the second leaf beating roller are both located in the leaf beating cavity, the first leaf beating roller and the second leaf beating roller are staggered on the same horizontal line, the blades on the adjacent first leaf beating rollers and the blades on the second leaf beating rollers are staggered, the first leaf beating roller shaft and the second leaf beating roller shaft are respectively rotatably connected to the leaf beating box shell; the first drive assembly is connected to multiple first leaf beating rollers to drive multiple first leaf beating rollers to rotate in the leaf beating cavity, the second drive assembly is connected to multiple second leaf beating rollers to drive multiple second leaf beating rollers to rotate in the leaf beating cavity, and the multiple first leaf beating rollers and the multiple second leaf beating rollers are located directly above the tobacco leaf discharging port.

[0013] Furthermore, the first transmission member 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 rotating shaft of the first frequency-modulated motor, the first driving pulley is transmission-connected to the first driven pulley sleeved on one of the first beating roller rotating shafts through the first driving conveyor belt, the first driven pulleys sleeved on each first beating roller rotating shaft are transmission-connected to each other through the first driven conveyor belt, and the rotating shafts of multiple first beating rollers are respectively rotationally connected to the beating box shell.

[0014] Furthermore, the second driving assembly includes a second driving source and a second transmission member; the second driving source is a second frequency-modulated motor, and the second frequency-modulated motor is respectively connected to the plurality of second beating rollers through the second transmission member.

[0015] Furthermore, the second transmission member 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 rotating shaft of the second frequency-modulated motor, and the second driving pulley is transmission-connected to the second driven pulley sleeved on one of the second beating roller rotating shafts through the second driving conveyor belt, and the second driven pulleys sleeved on each second beating roller rotating shaft are transmission-connected to each other through the second driven conveyor belt, and the rotating shafts of multiple second beating rollers are respectively rotationally connected to the beating box shell.

[0016] Furthermore, rectangular openings are respectively provided on the two side walls of the leaf beating box shell near the leaf beating cavity, and the rectangular openings are movably connected to the inspection door through an automatic opening and closing mechanism.

[0017] Furthermore, the automatic opening and closing mechanism includes a connecting web, a cylinder and a driving seat; the connecting webs are respectively connected to the outer wall of the leaf beating box shell near the rectangular opening, the two connecting web ends are hinged to the arc-shaped rotating strips connected to the outer wall of the inspection door, the driving seat connected to the top side wall outside the inspection door is hinged to the cylinder driving end, and the two cylinder fixed ends are respectively rotatably connected to the connecting seats connected to the outer wall of the leaf beating box shell.

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

[0019] Furthermore, a first semicircular through groove is provided at the bottom of the inspection door, and the first semicircular through groove and the second semicircular through groove provided on the rectangular open side wall are pieced together to form a circular through groove for rotationally connecting the first beating roller shaft or the second beating roller shaft, and the 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 push buckle, and the buckle hook in the first push buckle passes through the rectangular groove at the top of the inspection door and is buckled with the first U-shaped buckle groove, and the first U-shaped buckle groove is arranged on the outer wall of the leaf beating box shell near the rectangular opening.

[0021] Furthermore, a frame with arc-shaped transitions at both ends is arranged in the beating box shell near the tobacco leaf discharge port, the frame is located directly below the first beating roller and the first beating roller, and the frame is located directly above the tobacco leaf discharge port.

[0022] Furthermore, one end of the end wall of part of the leaf beating box shell near the frame is hinged to the leaf beating box shell, and a second U-shaped buckle groove at the other end of the end wall of the part of the leaf beating box shell is buckled with a hook in the second press buckle on the outer wall of the leaf beating box shell near the tobacco leaf discharge port, and the two side walls of the frame can be connected to the inner wall of the leaf beating box shell where the second press buckle is set.

[0023] During the working process, when the tobacco leaves are beaten by the leaf beating machine, the first driving component and the second driving component can be started, so that the first driving component drives multiple first leaf beating rollers to rotate clockwise or counterclockwise in the leaf beating chamber and the second driving component drives multiple second leaf beating rollers to rotate clockwise or counterclockwise at a suitable speed in the leaf beating cavity. When the multiple first leaf beating rollers rotate clockwise or counterclockwise in the leaf beating cavity and the second driving component drives the multiple second leaf beating rollers to rotate clockwise or counterclockwise at a suitable speed in the leaf beating cavity, a cutting area for the tobacco leaves is formed between the adjacent first leaf beating rollers and the second leaf beating rollers. Under the influence of the speed difference between the adjacent first leaf beating rollers and the second leaf beating rollers, the tobacco leaves entering the cutting area can tear the leaves multiple times for each rotation of the first leaf beating roller and the second leaf beating roller, thereby indirectly improving the leaf beating efficiency. Then, the cut and beaten tobacco leaves fall through the tobacco leaf discharge port into the subsequent tobacco leaf processing process for further processing.

[0024] During the tobacco leaf threshing process, if it is necessary to ensure that the cut tobacco leaves have a certain size, the first driving component drives the first leaf threshing roller to rotate clockwise at a suitable speed in the leaf threshing cavity and the second driving component drives the second leaf threshing roller to rotate counterclockwise at a suitable speed in the leaf threshing cavity, or the first driving component drives the first leaf threshing roller to rotate counterclockwise at a suitable speed in the leaf threshing cavity and the second driving component drives the second leaf threshing roller to rotate clockwise at a suitable speed in the leaf threshing cavity. In this way, the adjacent first leaf threshing roller and the second leaf threshing roller rotate in opposite directions, and the tobacco leaves fall. In the cutting area between the first beating roller and the second beating roller rotating in opposite directions, on the one hand, due to the speed difference between the first beating roller and the second beating roller in up and down motion, and on the other hand, due to the synchronous upward throwing of the first beating roller and the second beating roller, the cutting of tobacco leaves formed between the first beating roller and the second beating roller is not obvious, and the tobacco leaf cutting surface formed between the first beating roller and the second beating roller is not only reduced by half, but also the first beating roller and the second beating roller rotating in opposite directions also improve the effect of throwing tobacco leaves downward, avoiding the situation of excessive beating times of tobacco leaves, so that the tobacco leaves beaten out have a certain size;

[0025] During the tobacco leaf threshing process, if the material entering the threshing machine is less or the leaves are too large after threshing, the first driving component drives the first beating roller to rotate clockwise at an appropriate speed in the beating chamber and the second driving component drives the second beating roller to rotate clockwise at an appropriate speed in the beating chamber, or the first driving component drives the first beating roller to rotate counterclockwise at an appropriate speed in the beating chamber and the second driving component drives the second beating roller to rotate counterclockwise at an appropriate speed in the beating chamber. In this way, the adjacent first beating rollers and the second beating rollers rotate in the same direction. When the tobacco leaves fall into the cutting area between the first beating roller and the second beating roller rotating in the same direction, there is a certain amount of material thrown upward and downward between the first beating roller and the second beating roller rotating in the same direction. Under the influence of the mutual offset between the thrown material and the downward thrown material, and under the movement trend of the first beating roller and the second beating roller and the gravity factor, the tobacco leaves passing through the cutting area between the first beating roller and the second beating roller are cut multiple times per unit time, so that the specifications of the beaten leaves are reduced; in this beating process, if the first beating roller and the second beating roller rotating in the same direction have the largest speed and the largest number of cutting times, the speed of the first drive component is reduced or the speed of the second drive component is reduced, so that the speed of the first beating roller connected to the first drive component or the second beating roller connected to the second drive component is reduced, so that the tobacco leaves passing between the first beating roller and the second beating roller rotating in the same direction can reach a moderate number of cutting times, so as to beat out processing requirements that meet different process requirements.

[0026] During the tobacco leaf threshing process, if the amount of tobacco leaves near the two inner walls of the threshing machine is small and the amount of tobacco leaves in the middle of the threshing machine is large, the belt pulleys sleeved by the first beating roller shaft and the second beating roller shaft near the two inner walls of the threshing machine will be replaced with larger ones, and the belt pulleys sleeved by the first beating roller shaft and the second beating roller shaft near the middle of the threshing machine will be replaced with smaller ones. In this way, the rotation speed of the beating rollers in different parts can be appropriately adjusted by changing the size of the belt pulleys, which not only reasonably configures the rotation speeds of the first beating roller and the second beating roller, but also further improves the overall uniformity of the threshing.

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

[0028] 1. The present invention provides a first leaf beating roller driven by a first driving component and a second leaf beating roller driven by the first driving component in a leaf beating cavity of a leaf beating box shell, the first leaf beating roller and the second leaf beating roller are staggered on the same horizontal line, the blades on adjacent first leaf beating rollers and the blades on the second leaf beating rollers are staggered, so that when beating tobacco leaves, the adjacent first leaf beating rollers and the second leaf beating rollers can rotate relative to each other, and a cutting area for cutting tobacco leaves is formed between the adjacent first leaf beating rollers and the second leaf beating rollers. Under the influence of the speed difference between the adjacent first leaf beating rollers and the second leaf beating rollers, the tobacco leaves entering the cutting area can be torn multiple times for each rotation of the first leaf beating roller and the second leaf beating roller, thereby greatly improving the cutting efficiency of tobacco leaves, so as to solve the problem of low leaf beating and tearing rate of existing tobacco leaf beating machines when beating tobacco leaves.

[0029] 2. The present invention provides a first beating roller driven by a first drive assembly and a second beating roller driven by the first drive assembly in the beating cavity of the beating box shell. The first beating roller and the second beating roller are staggered on the same horizontal line, and the blades on the adjacent first beating rollers and the blades on the second beating rollers are staggered. That is, the method of beating tobacco leaves by cooperating with a moving knife in a traditional beating machine is changed to the method in which the blades on the first beating roller and the blades on the second beating roller move relative to each other to cut and beat the tobacco leaves in the present application, thereby indirectly reducing the probability of the first beating roller and the second beating roller getting stuck.

[0030] 3. The present invention provides a first leaf beating roller driven by a first driving component and a second leaf beating roller driven by the first driving component in the leaf beating cavity of the leaf beating box shell. The first leaf beating roller and the second leaf beating roller are staggered on the same horizontal line, and the blades on the adjacent first leaf beating rollers and the blades on the second leaf beating rollers are staggered. When different required tobacco leaf blades need to be processed or different processing conditions are faced, different specifications of leaf blades or different processing conditions can be processed according to the actual required processing. The first driving component is used to regulate the first leaf beating roller to rotate clockwise or counterclockwise at a certain speed and the second driving component is used to regulate the second leaf beating roller to rotate clockwise or counterclockwise at an appropriate speed. In this way, a cutting area for tobacco leaves is formed between the first leaf beating roller rotating at an appropriate speed and the second leaf beating roller rotating at an appropriate speed. The tobacco leaves entering the cutting area are beaten into leaves of different specifications to meet the processing requirements of different processes, so that the processing adjustment means are no longer single when processing different required tobacco leaf blades.

[0031] 4. The present invention configures the thresher body of the leaf thresher as a three-dimensional box structure, which not only reduces the space occupied by the three-dimensional box structure in the redrying workshop, but also makes the regular three-dimensional box structure easy to transport.

[0032] 5. The present invention provides rectangular openings on both side walls of the leaf box shell close to the leaf beating cavity. The rectangular opening 2 is movably connected to the inspection door through an automatic opening and closing mechanism. When the first leaf beating roller and the second leaf beating roller in the leaf beating cavity need to be maintained or overhauled, the inspection door covering the rectangular opening can be automatically opened through the automatic opening and closing mechanism, so that the inspection or maintenance personnel can inspect or maintain the first leaf beating roller and the second leaf beating roller in the leaf beating cavity.

[0033] 6. In the present invention, one end of the end wall of a part of the leaf beating box shell near the frame is hinged to the leaf beating box shell, and the second U-shaped buckle groove at the other end of the end wall of the part of the leaf beating box shell is buckled with the hook in the second push 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 push buckle is separated from the second U-shaped buckle groove, and then the end wall of the part of the leaf beating box shell is opened, and the frame appears in the operator's field of vision, and the operator can observe the material falling on the frame.

DETAILED DESCRIPTION

[0053] like Figure 1-18 In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0054] Example

[0055] The structure of the existing leaf beater is generally as follows: the main body of the machine is a rectangular cavity which is open at the bottom and the top, an arc-shaped cavity with a circular arc transition is connected to the side wall near the bottom of the rectangular cavity, a fixed leaf beater roller with a fixed knife and a dynamic leaf beater roller with a driving knife are arranged side by side inside the rectangular cavity on one side above the arc-shaped cavity with the circular arc transition, a screen is arranged in the rectangular cavity near the arc-shaped cavity with the circular arc transition, the fixed leaf beater roller with a fixed knife and the dynamic leaf beater roller with a driving knife are located above the screen, so as to constitute the most basic structure of the leaf beater. Although the leaf beater of this structure can also beat tobacco leaves, it still has the defects of low leaf beating and tearing rate and single processing and adjustment means when processing different required tobacco leaves.

[0056] Therefore, the present application proposes a high-efficiency multi-roller beating machine to solve the problems of low beating and tearing rate of tobacco leaves in existing tobacco beating machines and single processing and adjustment means when processing different required tobacco leaves.

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

[0058] In actual use, when the tobacco leaves are threshed by the threshing machine, the first driving assembly 7 and the second driving assembly 8 can be started, so that the first driving assembly 7 drives the plurality of first threshing rollers 5 to rotate clockwise or counterclockwise at a suitable speed in the threshing cavity 3 and the second driving assembly 8 drives the plurality of second threshing rollers 6 to rotate clockwise or counterclockwise at a suitable speed in the threshing cavity 3. When 6 rotates clockwise or counterclockwise at a suitable speed in the beating cavity 3, a cutting area for tobacco leaves is formed between the adjacent first beating rollers 5 and the second beating rollers 6. Under the influence of the speed difference between the adjacent first beating rollers 5 and the second beating rollers 6, the tobacco leaves entering the cutting area can be torn multiple times for each rotation of the first beating rollers 5 and the second beating rollers 6, thereby indirectly improving the beating efficiency. Then, the cut and beaten tobacco leaves fall through the tobacco leaf discharge port into the subsequent tobacco leaf processing process for further processing.

[0059] During the tobacco leaf beating process, if it is necessary to ensure that the cut tobacco leaves have a certain size, the first driving component 7 drives the first beating roller 5 to rotate clockwise at a suitable speed in the beating cavity 3 and the second driving component 8 drives the second beating roller 6 to rotate counterclockwise at a suitable speed in the beating cavity 3. Alternatively, the first driving component 7 drives the first beating roller 5 to rotate counterclockwise at a suitable speed in the beating cavity 3 and the second driving component 8 drives the second beating roller 6 to rotate clockwise at a suitable speed in the beating cavity 3. In this way, the adjacent first beating roller 5 and the second beating roller 6 rotate in opposite directions, and the tobacco leaves are cut into small pieces. When the leaves fall into the cutting area between the first beating roller 5 and the second beating roller 6 which rotate in opposite directions, on the one hand, due to the speed difference between the first beating roller 5 and the second beating roller 6 in up and down motion, on the other hand, due to the fact that the first beating roller 5 and the second beating roller 6 simultaneously throw the material upward, the cutting is not obvious. The cutting surface of the tobacco leaves formed between the first beating roller 5 and the second beating roller 6 is not only reduced by half, but also the first beating roller 5 and the second beating roller 6 which rotate in opposite directions also improve the effect of throwing the tobacco leaves downward, thus avoiding the situation that the tobacco leaves are beaten too many times, so that the beaten tobacco leaves have a certain size.

[0060] During the tobacco leaf threshing process, if the material entering the threshing machine is less or the leaves are too large after threshing, the first driving component 7 drives the first threshing roller 5 to rotate clockwise at an appropriate speed in the threshing cavity 3 and the second driving component 8 drives the second threshing roller 6 to rotate clockwise at an appropriate speed in the threshing cavity 3, or the first driving component 7 drives the first threshing roller 5 to rotate counterclockwise at an appropriate speed in the threshing cavity and the second driving component 8 drives the second threshing roller 6 to rotate counterclockwise at an appropriate speed in the threshing cavity 3. In this way, the adjacent first threshing rollers 5 and the second threshing rollers 6 rotate in the same direction. When the tobacco leaves fall into the cutting area between the first threshing rollers 5 and the second threshing rollers 6 rotating in the same direction, there is a certain amount of upward and downward throwing between the first threshing rollers 5 and the second threshing rollers 6 rotating in the same direction. Under the influence of mutual offset, coupled with the movement trend of the first beating roller 5 and the second beating roller 6 and the gravity factor, the tobacco leaves passing through the cutting area between the first beating roller 5 and the second beating roller 6 are cut multiple times per unit time, so that the specifications of the beaten leaves are reduced; in this beating process, if the first beating roller 5 and the second beating roller 6 rotating in the same direction have the maximum speed and the maximum number of cutting times, the speed of the first drive component 7 is reduced or the speed of the second drive component 8 is reduced, so that the speed of the first beating roller 5 connected to the first drive component 7 or the speed of the second beating roller 6 connected to the second drive component 8 is reduced, so that the tobacco leaves passing between the first beating roller 5 and the second beating roller 6 rotating in the same direction can reach an appropriate number of cutting times, so as to beat out the tobacco leaves that meet the processing requirements of different processes, so that when processing different required tobacco leaves, the processing adjustment means are no longer single.

[0061] See also Figure 6 and Figure 2 The first driving component 7, which is used to drive the multiple first beating rollers 5 to rotate clockwise or counterclockwise at a suitable speed in the beating cavity 3, includes a first driving source and a first transmission member 9; wherein the first driving source is used to drive the first transmission member 9 to transmit; the first transmission member 9 is used to drive the multiple first beating rollers 5 in the 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 , and the first frequency-modulated motor 10 is respectively connected to the plurality of first beating rollers 5 through the first transmission member 9 .

[0063] In actual use, when the first driving component 7 drives the multiple first leaf beating rollers 5 to rotate clockwise or counterclockwise at a certain speed, the first speed-regulating motor 10 rotates forward, and the output shaft of the forward-rotating first frequency-regulating motor 10 drives the multiple first leaf beating rollers 5 connected to the first transmission member 9 to rotate clockwise at a suitable speed through the first transmission member 9.

[0064] When the first driving component 7 drives the multiple first beating rollers 5 to rotate counterclockwise at a suitable speed, the first speed-regulating motor 10 rotates in the opposite direction.
