Description

Technical Field

[0001] This application relates to the field of tobacco processing equipment technology, and in particular to a blade for cutting long tobacco shreds. Background Technology

[0002] In tobacco processing, cutting long tobacco shreds is a crucial step that determines the quality of the tobacco. Traditional tobacco cutting blades suffer from the problem of tobacco shreds easily tangling, making it difficult to meet production demands in terms of cutting efficiency and tobacco quality. Utility Model Content

[0003] To solve the problem of traditional cutting blades easily getting tangled with tobacco, this utility model provides a long tobacco cutting blade, including: a cutting blade body; Multiple blade bodies are suitable for being arranged in an array on the outer wall of a vertical rotating shaft; The main body of the cutting tool includes a tool holder and a blade. The tool holder is a plate-shaped structure with a preset thickness, suitable for being embedded in a groove on the outer wall of the vertical rotating shaft. The blade is a sheet-shaped structure with a preset length, the end of which is fixedly connected to the plate surface of the tool holder, and the plate surface of the blade is perpendicular to the axial length direction 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 shaft.

[0004] In one possible implementation, the blade is a plate-like structure with thickness.

[0005] In one possible implementation, one end of the blade is a fixed end along its length, and the other end is a cutting end; The fixed end of the blade is fixedly connected to the blade holder; The cutting end of the blade extends away from the fixed end, and one end of the cutting end along the width direction of the blade is an abutting end, while the other end is a turning end. The turning end of the blade is bent at a preset angle toward the fixed end of the blade, and the preset angle is in the range of 30-60 degrees.

[0006] In one possible implementation, the turning end of the blade is located above the abutting end of the blade.

[0007] In one possible implementation, the cross-section of the tool holder is square.

[0008] In one possible implementation, the plate surface of the tool holder is provided with a fixing hole, and the tool body is bolted to the vertical rotating shaft through the fixing hole; There are two fixing holes, which are respectively located on both sides of the blade plate.

[0009] In one possible implementation, the end of the blade is located at the center of the plate surface of the blade holder.

[0010] In one possible implementation, the blade's surface is recessed with a flow channel.

[0011] In one possible implementation, both the blade and the blade holder are made of stainless steel.

[0012] In one possible implementation, the length direction of the cutting tool body is adapted to be perpendicular to the outer wall of the vertical rotating shaft.

[0013] The beneficial effects of the long tobacco cutting blades in this embodiment are as follows: The arrayed blade body forms a continuous cutting area, which, combined with the circular motion of the vertical rotating shaft, increases the cutting contact area per unit time. Specifically, the blade surface rotates circumferentially around its length, and the rotation direction of the blade is the same as the rotation direction of the vertical rotating shaft. This allows the tobacco to naturally unfold during the spinning process, avoiding the tobacco clumps caused by the squeezing cutting of traditional straight blades, and cutting long tobacco or tobacco clumps into medium and short shreds through multiple spinning cuts. Specifically, when the blade is cutting and spinning long tobacco or tobacco clumps, the side of the blade that is not twisted along its length is used to cut the long tobacco or tobacco clumps, while the side that is twisted along its length is used to throw the long tobacco or tobacco clumps onto the sidewall of the overall structure, further improving the efficiency of cutting and spinning long tobacco and tobacco clumps.

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.

[0022] like Figures 1-5 As shown, the long tobacco cutting blade of this application embodiment includes: a cutting blade body 1, and multiple cutting blade bodies 1 are suitable for being arranged in an array on the outer side wall of the vertical rotating shaft 2. The cutting blade body 1 includes a blade holder 11 and a blade 10. The blade holder 11 is a plate-shaped structure with a preset thickness, which is suitable for being embedded in a groove on the outer side wall of the vertical rotating shaft 2. The blade 10 is a sheet-shaped structure with a preset length, and its end is fixedly connected to the plate surface of the blade holder 11. The plate surface of the blade 10 is perpendicular to the axial length direction of the vertical rotating shaft. The plate surface of the blade 10 is circumferentially twisted around the length direction, and the twisting direction of the blade 10 is the same as the rotation direction of the vertical rotating shaft 2.

[0023] In this specific embodiment, the arrayed blade bodies 1 form a continuous cutting area. Combined with the circular motion of the vertical rotating shaft 2, this increases the cutting contact area per unit time. Specifically, the blade surface rotates circumferentially along its length, and the rotation direction of the blade 10 is the same as the rotation direction of the vertical rotating shaft 2. This allows the tobacco shreds to naturally unfold during the rotating process, avoiding the tobacco shreds clumping caused by the squeezing cutting of traditional straight blades 10. Long tobacco shreds or tobacco clumps are then repeatedly rotated and cut into medium-short shreds. Specifically, when the blade 10 cuts and rotates long tobacco shreds or tobacco clumps, the side of the blade 10 that is not rotated along its length is used to cut the long tobacco shreds or tobacco clumps, while the side of the blade 10 that is rotated along its length is used to throw the long tobacco shreds or tobacco clumps onto the sidewall of the overall structure, further improving the efficiency of rotating and cutting long tobacco shreds and tobacco clumps.

[0024] The blade holder 11 is a plate-shaped structure with a preset thickness, which fits into the groove on the outer wall of the vertical rotating shaft 2 and can be stably embedded therein, providing a mounting base for the blade 10. The blade 10 is a sheet-shaped structure with a preset length, and its end is fixedly connected to the plate surface of the blade holder 11. The plate surface of the blade 10 is perpendicular to the axial length direction of the vertical rotating shaft 2 to ensure effective transmission of cutting force. The plate surface of the blade 10 is circumferentially twisted along the length direction, and the twisting direction is the same as the rotation direction of the vertical rotating shaft 2. This allows for the simultaneous twisting of long tobacco shreds and tobacco clumps while cutting, improving the efficiency of cutting long tobacco shreds and tobacco clumps into short tobacco shreds.

[0025] In one specific embodiment, the blade 10 is a plate-like structure with thickness. Compared with a traditional thin blade 10, the thick plate-like blade 10 has improved bending strength and avoids deformation under high-speed rotation of the vertical rotating shaft 2. Moreover, the thickness structure disperses the force on the blade edge, reduces the pressure per unit area, ensures cutting force while reducing excessive breakage of tobacco shreds.

[0026] In one specific embodiment, multiple blade bodies 1 are suitable for being disposed on the outer side wall of the vertical rotating shaft 2, and the cutting edge direction of the blades 10 of two adjacent blade bodies 1 is alternately arranged towards the next layer of blade bodies 1.

[0027] In one specific embodiment, one end of the blade 10 along its length is a fixed end 102, and the other end is a cutting end 102. The fixed end 102 of the blade 10 is fixedly connected to the blade holder 11. The cutting end 102 of the blade 10 extends away from the fixed end 102. The cutting end 102 along the width direction of the blade 10 is an abutting end 104, and the other end is a turning end 103. The turning end 103 of the blade 10 is bent at a preset angle toward the fixed end 102 of the blade 10. The preset angle is in the range of 30-60 degrees.

[0028] In this specific embodiment, the rotating end 103, which is bent at 30-60 degrees, forms a progressive cutting angle. First, the tobacco shreds are combed by the rotating end 103 of the blade 10, and then the fixed-length cutting is completed by the contact end 104 of the blade 10, which solves the problem of uneven length caused by the traditional blade 10 cutting in one stroke.

[0029] Moreover, the bending structure causes the cut tobacco shreds to fall off along the bevel of the blade edge, and combined with the centrifugal force of rotation, the tobacco shred entanglement rate is reduced. In a specific embodiment, the rotating end 103 of the blade 10 is located above the abutting end 104 of the blade 10.

[0030] In one specific embodiment, the cross-section of the tool holder 11 is square. The square cross-section of the tool holder 11 forms a surface contact with the groove for positioning, reducing installation errors. Specifically, the outer wall of the vertical rotating shaft 2 has a groove that matches the tool holder 11, used to fix and install the tool holder 11 of the cutting tool body. The groove has a square cross-section that matches the cross-section of the tool holder 11, allowing the tool holder 11 of the cutting tool body to be embedded inside the groove.

[0031] In one specific embodiment, the rotating end 103 is located above the abutting end 104. When the main body 1 of the breaker is mounted on the vertical rotating shaft 2, the rotating end 103 of the blade 10 is located above the abutting end 104 of the blade 10. This allows the surface of the blade 10 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.

[0032] In one specific embodiment, the blade holder 11 has fixing holes 111 on its plate surface. The blade body 1 is bolted to the vertical rotating shaft 2 through the fixing holes 111. There are two fixing holes 111, respectively located on both sides of the blade 10 plate surface. The symmetrical arrangement of the two fixing holes 111 on both sides of the blade 10 ensures that the bolts are subjected to uniform force, eliminating the risk of loosening under high-frequency vibration. In addition, the bolt connection method reduces the replacement time of the blade 10.

[0033] In one specific embodiment, the end of the blade 10 is located in the middle of the plate surface of the blade holder 11. The blade 10 is fixed in the center so that the torque difference between the two ends of the blade holder 11 is close to zero, avoiding deformation of the blade holder 11 caused by unilateral force, extending the service life of the blade holder 11. Moreover, the central layout ensures the concentricity of the rotation trajectory of the blade 10, and the overlapping area of ​​multiple blades 10 is controlled within a very small range.

[0034] In one specific embodiment, the blade 10 has a recessed guide groove on its plate surface. By bending the rotating end 103 of the blade 10 toward the fixed end 102 of the blade 10, a guide groove with a recessed structure is formed, which can wrap a certain amount of long tobacco shreds or tobacco clumps and throw them onto the outer sidewall, thereby loosening the long tobacco shreds and tobacco clumps.

[0035] In one specific embodiment, both the blade 10 and the blade holder 11 are made of stainless steel.

[0036] In one specific embodiment, the length direction of the blade body 1 is adapted to be perpendicular to the outer wall of the vertical rotating shaft 2, and the blade body 1 is perpendicular to the rotating shaft 2, so that the effective cutting radius of the blade 10 is increased compared with the traditional inclined layout.

[0037] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. 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.
