Abstract
Description
Technical Field
[0001] This application relates to the field of tobacco processing equipment technology, and in particular to a vertical leaf spinning device. Background Technology
[0002] In the processing of slim tobacco cigarettes, the looseness and uniformity of the tobacco leaves directly affect the product quality of subsequent rolling processes. Therefore, the length grading of tobacco leaves directly impacts the quality of subsequent cigarette rolling, with medium-short tobacco leaves meeting the requirements. However, due to the sheet structure of existing tobacco cutting machines, a large amount of long tobacco leaves are produced after cutting, and some of these long leaves may even clump together, failing to meet actual needs. Currently, most commonly used tobacco leaf shredding equipment in the industry has a horizontal structure, with the blades arranged in a single direction, enabling only simple striking and failing to perform fine combing of the tobacco leaves, easily resulting in excessive breakage of the leaves. Summary of the Invention To address the limitation of traditional horizontal rotary beaters that can only simply beat long tobacco shreds, this invention provides a vertical leaf-beater, comprising: Rotary striking housing, vertical rotating housing, striking blade, and drive motor; The rotary shell has a hollow structure with a tobacco inlet hole at the top and a tobacco outlet hole at the bottom. The vertical rotating housing is disposed inside the rotary housing, and the vertical rotating housing is a hollow columnar structure with an opening at the bottom; The blade is a sheet-like structure, with one end connected to the outer wall of the vertical rotating housing and the other end extending toward the inner wall of the rotating housing. There are multiple blades, which are spaced apart along the circumferential and axial directions of the vertical rotating housing. The output end of the drive motor is connected to the vertical rotating housing, driving the vertical rotating housing to rotate around the axial direction.
[0003] One possible implementation also includes: a speed reducer and a rotary shaft; One end of the rotary shaft is connected to the inner top flange of the vertical rotary housing; The reducer is connected to the other end of the rotary shaft via a coupling; The drive motor is connected to the other end of the rotary shaft via a drive belt.
[0004] One possible implementation also includes: a deflector plate; The guide plate is a ring structure and is disposed inside the rotary shell. The outer ring of the guide plate is fixedly connected to the side wall of the rotary shell. Multiple guide plates are disposed at intervals on the inner side wall of the rotary shell along the height direction of the rotary shell. The guide plate has an inverted frustum structure with openings at both ends, and the surface of the guide plate is inclined toward the bottom of the rotary housing.
[0005] In one possible implementation, the cutting blade and the guide plate are arranged alternately at intervals, with a preset distance between them.
[0006] In one possible implementation, two or more blades are provided between any two adjacent guide vanes.
[0007] One possible implementation also includes: an allocator; The distributor is located at the top of the vertical rotating shaft; The distributor includes multiple distribution plates, which are spaced apart along the circumferential direction of the vertical rotation axis. The distribution plate is a plate-shaped structure with a preset length. One side of the width direction is fixedly connected to the top position of the vertical rotating shaft. The plate surface is parallel to the axial direction of the vertical distributor. One end of the distribution plate in the length direction faces the top edge of the vertical rotating shaft, and the other end faces the top center of the vertical rotating shaft.
[0008] In one possible implementation, the surface of the distribution plate has a preset curvature; The bending direction of the distribution plate is the same as the bending direction of the cutting tool; The end of the distribution plate that is close to the edge of the vertical rotating shaft is the free end, and the ends of any two distribution plates that are away from the free end are spaced apart by a preset distance; The free end of the distribution plate is flush with the top edge of the vertical rotating shaft.
[0009] In one possible implementation, the cross-sectional diameter of the vertical rotating housing gradually increases from the top to the bottom of the vertical rotating housing; The length direction of the cutting blade is perpendicular to the side wall of the vertical rotating housing; The sidewalls of the rotary shell are inclined, the cross-sectional area gradually increases from the top to the bottom, and the outer sidewalls of the rotary shell are provided with reinforcing ribs.
[0010] In one possible implementation, the cutting tool body includes: a tool holder and a blade; The blade holder is a plate-shaped structure with a preset thickness, suitable for being embedded in a groove on the outer side wall of the vertical rotating housing. The blade is a sheet-shaped structure with a preset length, the end of which is fixedly connected to the plate surface of the blade holder, and the plate surface of the blade is perpendicular to the side wall of the vertical rotating shaft. The blade plate is circumferentially twisted around its length, and the twisting direction of the blade is the same as the rotation direction of the vertical rotating housing.
[0011] One possible implementation also includes: a dust collection hood; The dust collection hood is positioned directly above the feed inlet.
[0012] The beneficial effects of the vertical tobacco shredding device in this application embodiment are as follows: The vertical rotating shell drives the multi-dimensionally distributed cutting blades to rotate, forming a three-dimensional cutting and shredding structure in both circumferential and axial directions. This allows for all-around cutting of tobacco shreds, avoiding the unevenness caused by cutting in a single direction. The annular structure with an inclined guide plate guides the tobacco shreds to move along a preset path to the bottom, preventing the tobacco shreds from accumulating in the shredding shell. Each layer functions to guide the tobacco shreds towards the central axis in a graded manner, avoiding uneven cutting caused by dispersion. The tobacco shreds fall into the cutting area of the next layer of cutting blades, which has multiple layers of cutting blades. During the cutting process of the next layer of cutting blades, the tobacco shreds fly onto the cylinder wall of the shredding shell under the centrifugal force of the shredding rotor. The cutting blades cannot reciprocate below the wall gap of the shredding shell. The guide plate located between the first layer of cutting blades and the next layer of cutting blades is arranged sequentially, allowing the long tobacco shreds or tobacco clumps to return to the cutting blades for further cutting, thus improving the cutting efficiency of long tobacco shreds or tobacco clumps. In addition, the vertical layout compresses the processing space along the height direction, which is suitable for the compact layout requirements of cigarette factory workshops.

Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.
[0021] like Figure 1As shown, the vertical tobacco shredding device of this application embodiment includes: a shredding housing 10, a vertical rotating housing 20, a cutting blade 30, and a drive motor 60. The shredding housing 10 is a hollow structure with a tobacco shredding inlet at the top and a tobacco shredding outlet at the bottom. The vertical rotating housing 20 is disposed inside the shredding housing 10 and is a hollow cylindrical structure with an opening at the bottom. The cutting blade 30 is a sheet-like structure with its edge connected to the outer wall of the vertical rotating housing 20. There are multiple cutting blades 30, which are spaced apart along the circumferential and axial directions of the vertical rotating housing 20. The discharge component 110 is a rod-like structure with its end connected to the outer wall of the vertical rotating housing 20. The output end of the drive motor 60 is connected to the vertical rotating housing 20, driving the vertical rotating housing 20 to rotate around the axial direction.
[0022] In this specific embodiment, the vertical rotating housing 20 drives the multi-dimensionally distributed cutting blades 30 to rotate, forming a three-dimensional cutting and swirling structure in both the circumferential and axial directions. This allows for all-around cutting of the tobacco, avoiding the unevenness caused by cutting in one direction. The annular structure with an inclined surface of the guide plate 40 guides the tobacco along a preset path to the bottom, preventing the tobacco from accumulating inside the swirling housing 10. Each layer functions to guide the tobacco towards the central axis in a graded manner, avoiding dispersion that could lead to uneven cutting. The tobacco falls into the layer above. The cutting blade 30 working area is equipped with multiple layers of cutting blades 30. During the operation of the previous layer of cutting blades 30, the tobacco shreds are propelled onto the cylinder wall of the rotating shell 10 by the centrifugal force of the rotating rotor. The cutting blades 30 cannot reciprocate within the gap between themselves and the wall of the rotating shell 10. A guide plate 40, located between the upper first layer of cutting blades 30 and the lower layer of cutting blades 30, is arranged sequentially to allow the long tobacco shreds or clumps to return to the cutting blades 30 for further cutting, thus improving the cutting efficiency of long tobacco shreds or clumps. Furthermore, the vertical layout compresses the processing space along the height, suitable for the compact layout requirements of cigarette factory workshops.
[0023] Specifically, the rotary housing 10 is a closed cavity with openings at the top and bottom, and is a hollow structure. The interior forms a space for rotating tobacco leaves. The top has a tobacco inlet hole, serving as the initial entry point for long tobacco leaves into the equipment, while the bottom has a tobacco outlet hole, acting as the discharge channel for the rotated tobacco leaves. The rotary housing 10 acts as the outer frame of the equipment, constraining the movement of the tobacco leaves within the internal space and preventing leaf splashing. The vertical rotating housing 20 is located at the very center of the rotary housing 10. It is a hollow columnar structure, similar to a vertically placed hollow cylinder, with an opening at the bottom for mounting the rotating shaft 90. The vertical rotating housing 20 serves as the moving carrier, housing the cutting blade 30 and the discharge component 110. Its own rotation drives the cutting blade 30 to rotate synchronously. The striking blade 30 is a sheet-like metal structure, with its edge bolted to the outer wall of the vertical rotating housing 20. There are multiple striking blades 30, which are distributed at intervals around the vertical rotating housing 20 in both the circumferential and vertical directions. The striking blades 30 directly contact the long tobacco shreds and strike the long tobacco shreds and tobacco clumps with the impact force generated by high-speed rotation, breaking up and loosening the clumps of tobacco leaves. The circumferential and axial spacing can cover the entire space around the vertical rotating housing 20, preventing the tobacco leaves from being missed.
[0024] like Figure 1 As shown, the discharge component 110 is a horizontally extending rod-shaped structure, with one end connected to the outer wall of the vertical rotating housing 20 and able to rotate synchronously with the vertical rotating housing 20, while the other end is suspended in the air. The bottom of the discharge component 110 is flush with the surface, forming a planar structure, and is attached to the bottom wall of the rotating housing 10. After the tobacco is shredded and cut, it falls onto the bottom wall of the rotating housing 10 or is discharged directly from the discharge hole. However, when short tobacco shreds fall onto the bottom wall of the rotating housing 10, the rotating discharge component 10 can sweep the tobacco shreds into the discharge hole.
[0025] In one specific embodiment, such as Figure 1 As shown, it also includes: a reducer 80 and a rotary shaft. One end of the rotary shaft is connected to the inner top flange of the vertical rotary housing 10. The reducer 80 is connected to the other end of the rotary shaft through a coupling. The drive motor 60 is connected to the other end of the rotary shaft through a drive belt 70.
[0026] In this specific embodiment, the reducer 80 and the drive motor 60 cooperate with each other to drive the cutting blade 30 on the vertical rotating housing 20 to rotate around the axis of the rotating shaft, thereby completing the rotary cutting of long tobacco shreds and tobacco shred patterns.
[0027] In one specific embodiment, such as Figure 3 and Figure 4As shown, it also includes: a guide plate 40, which is a ring structure and is disposed inside the rotary housing 10. The outer ring of the guide plate 40 is fixedly connected to the side wall of the rotary housing 10. Multiple guide plates 40 are disposed at intervals on the inner side wall of the rotary housing 10 along the height direction of the rotary housing 10. The guide plate 40 is an inverted frustum structure with openings at both ends, and the plate surface of the guide plate 40 is inclined towards the bottom of the rotary housing 10.
[0028] In this specific embodiment, the inclined surface of the inverted frustum-shaped guide plate 40 uses gravity to guide the tobacco filaments to gather towards the center of the shell and then flow downwards, avoiding the tobacco filaments from adhering to the inner wall of the rotary shell 10, ensuring that the tobacco filaments are in full contact with the cutting blade 30 for rotary cutting. The multi-layered guide plates 40 divide the interior of the rotary shell 10 into multiple independent processing zones. Long tobacco filaments and tobacco clumps enter the next level of cutting blade 30 for processing after passing through each layer of guide plates 40.
[0029] Specifically, such as Figure 3 As shown, the guide plate 40 is an annular plate structure. The outer ring edge is fixedly connected to the inner wall of the rotary housing 10, and they are spaced apart along the height direction of the rotary housing 10. The guide plate 40 has an inverted frustum structure, that is, the upper port diameter is small and the lower port diameter is large. The two ends are open for leaving a central hole for the vertical rotating housing 20 to pass through. The plate surface is inclined towards the bottom of the rotary housing 10, that is, it is inclined downward from the outer ring to the inner ring. It guides the tobacco filaments to move downward. When the tobacco filaments are impacted by the blasting blade 30, they will splash in all directions. After contacting the inclined guide plate 40, they will slide downward along the plate surface, preventing the tobacco filaments from accumulating at a certain height. At the same time, the annular structure can constrain the long tobacco filaments in the area between the guide plate 40 and the blasting blade 30, increasing the number of blows.
[0030] Furthermore, the cross-section of the guide plate 40 is circular, and the diameter of the cross-section gradually increases along the axial direction. This gradual increase in diameter also accommodates the expanded distribution range of the tobacco shreds due to diffusion during their descent, preventing the tobacco shreds from forming dead zones between the guide plate 40 and the sidewall of the rotating housing 10. The gradually changing flow channel slows down the falling speed of the tobacco shreds, prolonging the contact time between the tobacco shreds and the cutting blade 30, thus improving the cutting adequacy. In this way, the cross-section of the annular guide plate 40 is circular, gradually decreasing downwards, and the inner ring of the guide plate 40 is located above the cutting blade 30, allowing some of the rotated tobacco shreds to be returned to the cutting blade 30 for further rotation.
[0031] In one specific embodiment, such as Figure 3As shown, the cutting blade 30 and the guide plate 40 are staggered and spaced at a preset distance. The safe distance between the cutting blade 30 and the guide plate 40 prevents them from colliding during high-speed rotation. The reasonable preset distance provides sufficient cutting space for the tobacco, avoiding excessive compression that could cause the tobacco to break. This allows the tobacco to slide directly from the gap between the two blades after being spun and enter the cutting blade 30 below for further spun processing. The cutting blades 30 and guide plates 40 are arranged alternately along the axial direction, dividing the interior of the rotary casing 10 into multiple independent processing zones. This allows for multiple rotary cuts of long tobacco shreds and tobacco clumps, ensuring that the tobacco shreds are cut into suitable medium and short lengths. The staggered distribution of the cutting blades 30 and guide plates 40 causes the tobacco shreds to undergo a cycle of cutting, guiding, cutting, and re-guiding during their descent, achieving multiple cuts and improving the uniformity of the tobacco particle size. Furthermore, the staggered structure breaks the disordered descent path of the tobacco shreds, preventing them from sliding rapidly along a single channel and ensuring that each segment of tobacco shreds contacts the cutting blades 30. The sidewalls of the rotary casing 10 are inclined from the bottom to the top of the rotary casing 10.
[0032] Furthermore, the end of the guide plate 40 furthest from the rotating housing 10 is located above the end of the cutting blade 30 furthest from the vertical rotating housing 20. The inner ring end of the guide plate 40 is located above the outer end of the cutting blade 30, which can accurately guide the tobacco into the cutting area of the cutting blade 30, preventing the tobacco from bypassing the cutting blade 30 and falling directly, thus improving the cutting coverage. The height difference setting can prevent the tobacco from accumulating between the guide plate 40 and the cutting blade 30, ensuring a continuous and stable cutting process.
[0033] In one specific embodiment, two or more blades 30 are provided between any two adjacent guide plates 40.
[0034] In one specific embodiment, such as Figure 1 As shown, it also includes: a tobacco collection hood 50, which has an internal hollow structure and is open at both ends. The cross-section of the tobacco collection hood 50 is circular, and the cross-sectional area of the tobacco collection hood 50 gradually increases along the opening direction. The smaller end of the opening of the tobacco collection hood 50 is embedded in the first tobacco inlet hole. The flared structure of the tobacco collection hood 50 can expand the feeding range, adapt to the discharge end of the external feeding equipment, avoid tobacco scattering, and reduce material waste. The design of embedding the inlet hole at the smaller end of the opening can ensure that all tobacco enters the rotary housing 10, while preventing external impurities from entering and ensuring the purity of tobacco processing.
[0035] In one specific embodiment, such as Figure 1As shown, the feed hole has a circular cross-section, and its diameter is smaller than the diameter of the larger end of the tobacco collection hood 50. The larger end of the tobacco collection hood 50 faces outward and has a bent abutment. The feed hole diameter is smaller than the diameter of the larger end of the collection hood 50. With the abutment, the collection hood 50 can be stably fixed on the top of the rotary housing 10, preventing the collection hood 50 from shifting or falling off during feeding. The abutment increases the contact area between the collection hood 50 and the rotary housing 10, reducing local pressure, reducing component wear, and extending the service life of the equipment. At the same time, the abutment can cover the connection gap between the collection hood 50 and the feed hole, further preventing tobacco from scattering.
[0036] In one specific embodiment, such as Figure 3 and Figure 4 As shown, it also includes: a distributor, which is disposed at the top of the vertical rotating shaft. The distributor includes multiple distribution plates 100, which are spaced apart along the circumferential direction of the vertical rotating shaft. Each distribution plate 100 is a plate-shaped structure with a preset length. One side of the distribution plate 100 in the width direction is fixedly connected to the top of the vertical rotating shaft. The plate surface of the distribution plate 100 is parallel to the axial direction of the vertical distributor. One end of the distribution plate 100 in the length direction faces the top edge of the vertical rotating shaft, and the other end faces the top center of the vertical rotating shaft.
[0037] The distribution plates 100 are arranged at intervals along the circumferential direction of the vertical rotating housing 20. This circumferential arrangement of multiple distribution plates 100 allows for material distribution from multiple directions, further improving the uniformity of material distribution and ensuring more comprehensive contact between the material and the cutting blade 30, thus enhancing overall processing efficiency. Specifically, the multiple radial plate-like structures at the top of the vertical rotating housing 20 constitute the distribution plates 100, arranged at intervals along the circumference. The plates have a pre-set curvature, with the bending direction consistent with the cutting blade 30. The free ends of the distribution plates 100 are flush with the edge of the vertical rotating housing 20, and a pre-set spacing is maintained between the plates away from the free ends. When rotating synchronously with the vertical rotating housing 20, the distribution plates 100 evenly distribute the concentrated tobacco shreds to the circumferential area, preventing material accumulation in the center. The curvature and bending direction design ensures smoother tobacco flow.
[0038] In this specific embodiment, the distributor can distribute and guide the material when it enters the top of the cutter structure, so that the material is more evenly distributed around the vertical rotating housing 20, which facilitates the subsequent processing of long tobacco shreds and tobacco clumps by the cutting blade 30, and avoids the material from being concentrated in a certain area, which would affect the processing effect.
[0039] In one specific embodiment, such as Figure 3As shown, the surface of the distribution plate 100 has a preset curvature. Setting the preset curvature on the surface of the distribution plate 100 can better guide the flow of materials, make the materials flow more smoothly during the distribution process, reduce the accumulation of materials at the distribution plate 100, and improve the efficiency and effect of material distribution.
[0040] Furthermore, the bending direction of the distribution plate 100 is the same as that of the cutting knife 30. The fact that the distribution plate 100 and the cutting knife 30 have the same bending direction allows the long tobacco shreds to enter the working area of the cutting knife 30 more smoothly after being distributed by the distribution plate 100, which is compatible with the movement trajectory of the cutting knife 30 and improves the continuity and efficiency of the long tobacco shred processing.
[0041] Furthermore, the end of the distribution plate 100 that is close to the edge of the vertical rotating shaft is the free end, and the ends of any two distribution plates 100 that are far from the free end are spaced by a preset distance. This provides a channel for the flow of long tobacco from the center to the edge, so that the long tobacco can smoothly reach the working range of the cutting knife 30 after distribution, while also avoiding excessive crowding between the distribution plates 100, which would affect the flow of the long tobacco.
[0042] In one specific embodiment, the free end of the distribution plate 100 is flush with the top edge of the vertical rotating shaft, ensuring that when the long tobacco shreds reach the edge of the vertical rotating housing 20, they can come into more effective contact with the cutting blade 30, thereby improving the material processing effect of the cutting blade 30 and allowing the long tobacco shreds to be fully utilized by the cutting blade 30 at the edge.
[0043] In one specific embodiment, the cross-sectional diameter of the vertical rotating housing 20 gradually increases from the top to the bottom of the vertical rotating housing 20. The length direction of the cutting blade 30 is perpendicular to the side wall of the vertical rotating housing 20. The barrel-shaped structure of the vertical rotating housing 20, which is wider at the bottom and narrower at the top, allows the radial length of the bottom cutting blade 30 to be greater than that of the top cutting blade 30. This is suitable for the characteristics of the large quantity and high density of tobacco shreds at the bottom due to their aggregation, thereby improving the cutting efficiency of the tobacco shreds at the bottom.
[0044] Furthermore, such as Figure 1 As shown, the sidewalls of the rotary housing 10 are inclined, and the cross-sectional area gradually increases from the top to the bottom. The outer sidewalls of the rotary housing 10 are also equipped with reinforcing ribs. The inclination of the sidewalls of the rotary housing 10 matches the inclination of the sidewalls of the vertical rotary housing 20, thus improving space utilization.
[0045] Specifically, the rotary drum housing 10 has a columnar structure that is thinner at the top and thicker at the bottom, with the cross-sectional diameter gradually increasing from top to bottom. This design is adapted to the downward diffusion of tobacco shreds, and the larger space at the bottom can accommodate more dispersed tobacco shreds. Reinforcing ribs enhance the strength of the rotary drum housing 10, preventing deformation caused by impact from long tobacco shreds or equipment vibration.
[0046] In one specific embodiment, such as Figure 5 and Figure 6 As shown, the main body of the cutting knife 30 includes a knife holder 32 and a blade 31. The knife holder 32 is a plate-shaped structure with a preset thickness, suitable for being embedded in a groove on the outer side wall of the vertical rotating housing 20. The blade 31 is a sheet-shaped structure with a preset length, the end of which is fixedly connected to the plate surface of the knife holder 32. The plate surface of the blade 31 is perpendicular to the side wall of the vertical rotating shaft. The plate surface of the blade 31 is circumferentially twisted around its length, and the twisting direction of the blade 31 is the same as the rotation direction of the vertical rotating housing 20.
[0047] In this specific embodiment, the arrayed cutting blades 30 form a continuous cutting area. Combined with the circular motion of the vertical rotating housing 20, this increases the cutting contact area per unit time. Specifically, the blade 31's surface rotates circumferentially along its length, and the rotation direction of the blade 31 is the same as the rotation direction of the vertical rotating housing 20. This allows the tobacco shreds to naturally unfold during the rotating process, avoiding the agglomeration of tobacco shreds caused by the squeezing cutting of traditional straight blades 31. Long tobacco shreds or tobacco shreds are then flung onto the sidewalls of the overall structure, separating clumps of tobacco shreds and long tobacco shreds. Specifically, when the blade 31 cuts and rotates long tobacco shreds or tobacco shreds, the side of the blade 31 that is not rotated along its length is used to cut the long tobacco shreds or tobacco shreds, while the side of the blade 31 that is rotated along its length is used to flung the long tobacco shreds or tobacco shreds onto the sidewalls of the overall structure, further improving the efficiency of cutting and rotating long tobacco shreds and tobacco shreds.
[0048] Among them, such as Figure 5 and Figure 6 As shown, the blade holder 32 is a plate-shaped structure with a preset thickness, which fits into the groove on the outer wall of the vertical rotating housing 20 and can be stably embedded therein, providing a mounting base for the blade 31. The blade 31 is a sheet-shaped structure with a preset length, and its end is fixedly connected to the plate surface of the blade holder 32. The plate surface of the blade 31 is perpendicular to the axial length direction of the vertical rotating housing 20 to ensure effective transmission of cutting force. The plate surface of the blade 31 is circumferentially twisted along the length direction, and the twisting direction is the same as the rotation direction of the vertical rotating housing 20. This allows for simultaneous twisting and turning of long tobacco shreds and tobacco clumps while cutting, improving the efficiency of cutting long tobacco shreds and tobacco clumps into medium and short tobacco shreds.
[0049] The blade 31 is a thick plate-like structure. Compared with the traditional thin blade 31, the thick plate-like blade 31 has improved bending strength and avoids deformation under the high-speed rotation of the vertical rotating housing 20. Moreover, the thick structure disperses the force on the blade edge, reduces the pressure per unit area, ensures cutting force while reducing excessive breakage of tobacco.
[0050] The blade 31 has a fixed end at one end along its length and a cutting end at the other end. The fixed end of the blade 31 is fixedly connected to the blade holder 32. The cutting end of the blade 31 extends away from the fixed end. The cutting end is a contact end at one end along the width direction of the blade 31 and a turning end at the other end. The turning end of the blade 31 is bent at a preset angle toward the fixed end of the blade 31. The preset angle is in the range of 30-60 degrees.
[0051] The rotating end of the blade 31, bent at 30-60 degrees, forms a progressive cutting angle. First, the rotating end of the blade 31 combs the tobacco shreds, then the abutting end of the blade 31 cuts them to a fixed length, solving the problem of uneven lengths caused by the single cut of traditional blades 31. The bending structure causes the cut tobacco shreds to fall off along the beveled edge of the blade, and combined with the centrifugal force of rotation, the tobacco tangling rate is reduced. In one specific embodiment, the rotating end of the blade 31 is located above the abutting end of the blade 31.
[0052] Among them, such as Figure 5 and Figure 6 As shown, the cross-section of the tool holder 32 is square. The square cross-section of the tool holder 32 forms a surface contact with the groove for positioning, reducing installation errors. Specifically, the outer wall of the vertical rotating housing 20 has a groove that matches the tool holder 32, used to fix and install the tool holder 32 of the cutter body 30. The groove has a square cross-section that matches the cross-section of the tool holder 32, allowing the tool holder 32 of the cutter body 30 to be embedded inside the groove.
[0053] The rotating end is located above the abutting end. When the blade 30 is installed on the vertical rotating housing 20, the rotating end of the blade 31 is located above the abutting end of the blade 31. This allows the blade 31 to have a concave structure, which can wrap a certain amount of long tobacco shreds and tobacco clumps and throw them onto the outer side wall for loosening.
[0054] The tool holder 32 has mounting holes on its surface. Two blades 30 are bolted to the vertical rotating housing 20 through these holes, one on each side of the blade 31. The symmetrical arrangement of the two mounting holes on both sides of the blade 31 ensures even bolt stress, eliminating the risk of loosening under high-frequency vibration. Furthermore, the bolt connection method reduces the replacement time of the blade 31.
[0055] The end of the blade 31 is located in the middle of the plate surface of the tool holder 32. The blade 31 is fixed in the center so that the torque difference between the two ends of the tool holder 32 is close to zero, avoiding deformation of the tool holder 32 caused by unilateral force, extending the service life of the tool holder 32. The central layout ensures the concentricity of the rotation trajectory of the blade 31, and the overlapping area of multiple blades 31 is controlled within a very small range.
[0056] The blade 31 has a recessed guide groove on its surface. The blade 31 is bent towards the fixed end of the blade 31 to form a guide groove with a recessed structure. This guide groove can wrap a certain amount of long tobacco shreds or tobacco clumps and throw them onto the outer side wall, thus loosening the long tobacco shreds and tobacco clumps.
[0057] In one specific embodiment, both the blade 31 and the blade holder 32 are made of stainless steel. The length direction of the cutting blade 30 is adapted to be perpendicular to the outer wall of the vertical rotating housing 20. This arrangement of the cutting blade 30 perpendicular to the vertical rotating housing 20 increases the effective cutting radius of the blade 31 compared to a traditional inclined arrangement.
[0058] In one specific embodiment, it further includes a dust collection hood, which is positioned directly above the feed inlet to prevent dust from spreading when the tobacco is fed in.
[0059] In one specific embodiment, such as Figure 2 As shown, the feed hole of the vertical tobacco leaf rotary cutting device 1 is connected to the loosening vibration device 2. The loosening vibration device 2 is used to separate long tobacco leaves, medium and short tobacco leaves and tobacco residue, and to feed the long tobacco leaves into the vertical tobacco leaf rotary cutting device for rotary cutting.

Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
