For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0024] The present embodiment provides a stem and shred separation device to solve the problem that tobacco stems and shreds are easily formed into a group during the conveying process in the related art, resulting in low separation efficiency and poor separation effect in the subsequent process.

[0025] Please refer to Figure 1 , Figure 2 The present embodiment provides a stem and shred separation device for separating tobacco stems and shreds in the tobacco processing process. The stem and shred separation device comprises a dispersion assembly 100 and a conveying assembly 200. The dispersion assembly 100 comprises a shell 110, the shell 110 is provided with a feeding port 111 and a discharging port 112 which are in communication with the outside; a dispersion cavity is formed in the shell 110, a dispersion piece is installed in the dispersion cavity, the feeding port 111 and the discharging port 112 are both in communication with the dispersion cavity and are respectively arranged on the two sides of the dispersion piece. The conveying assembly 200 comprises at least two conveying belts 210, one end of one of the conveying belts 210 is arranged at the discharging port 112; the two conveying belts 210 are in material communication, and a winnowing piece 230 is arranged between the two conveying belts 210; a vibrating piece 220 is arranged on the conveying belt 210.

[0026] Specifically, when the tobacco stem and shreds separation device is used, the pretreated tobacco stems and shreds are sent to the dispersing assembly 100 and are sent to the dispersing cavity inside the shell 110 through the feeding port 111 of the shell 110. The tobacco stems and shreds are scattered by the dispersing member in the dispersing cavity, and the tobacco stems and shreds are rolled and loosened. Then, the tobacco stems and shreds fall from the discharge port 112 to the conveying belt 210.

[0027] The conveying belt 210 conveys the tobacco stems and shreds falling from the discharge port 112 to the direction of the winnowing member 230. During the conveying process, the vibration member 220 continuously vibrates the conveying belt 210 to vibrate the loosened tobacco stems and shreds on the conveying belt 210, so that the tobacco stems and shreds are separated from each other and no longer clump and entangle. After the conveying belt 210 sends the separated tobacco stems and shreds to the winnowing member 230, the winnowing member 230 separates the lighter shreds from above and the heavier stems fall from below to the next conveying belt 210. The conveying belt 210 sends the tobacco stems to the next process.

[0028] A small amount of shreds may still be mixed in the winnowed tobacco stems. During the conveying process of the conveying belt 210, the vibration member 220 still continuously vibrates the conveying belt 210 to further separate the small amount of shreds mixed in the winnowed tobacco stems.

[0029] The tobacco stem and shreds separation device of the embodiment loosens and vibrates the tobacco stems and shreds during the conveying process before separation, so that the tobacco stems and shreds are separated from each other and no longer clump and entangle, thereby improving the efficiency of the subsequent separation operation and improving the separation effect.

[0030] In one embodiment, as shown in Figure 1 , Figure 2 The inner wall of the dispersing cavity is arranged in an inverted conical shape, and the inner wall of the dispersing cavity is provided with the loosening teeth 114. The dispersing member is arranged as the roller 120, and the roller 120 is rotationally installed in the dispersing cavity to guide the tobacco stems and shreds to slide along the inner wall of the dispersing cavity. If the cavity is a straight cylinder or large at the top and small at the bottom, the tobacco stem and shreds mixture is easy to accumulate and block at the outlet, and the material arches above the outlet and cannot fall. The inverted conical inner wall actively guides the scattered material to converge to the discharge port 112 at the center bottom by using gravity and geometric shape. The slope design has no horizontal or reverse steps, and the material is not easy to accumulate on the wall, ensuring that the material continuously and stably flows out. The slope also increases the component force of the material sliding down, and accelerates the flow speed.

[0031] The dispersing member is the core of active dispersion, and the sparse teeth 114 on the inner wall provide passive dispersion assistance. When the roller 120 extrudes or pushes the material towards the inner wall, the material will scratch and collide with the sparse teeth 114 on the inner wall. The sparse teeth 114 can be inserted into the material group, tear the wrapped tobacco, and separate the adhered cut tobacco. At the same time, the roller pressing of the dispersing member and the combing of the sparse teeth 114 combine to form a composite dispersion mechanism, which is better than single roller pressing or combing. In addition, the sparse teeth 114 cover the entire inner wall of the dispersion cavity, so that the dispersion effect is throughout the cavity, not just limited to the vicinity of the roller 120, and the dispersion is more uniform and thorough.

[0032] In addition, the material enters the dispersion cavity from the feed inlet 111; the rotating dispersing member applies pressure and shear force to the material for preliminary dispersion and roller pressing; the material affected by the dispersing member is pushed towards the inverted conical inner wall and collides and scratches with the sparse teeth 114 for secondary dispersion and combing; the dispersed material smoothly slides between the sparse teeth 114 under the guidance of gravity and the inverted conical slope; during the sliding process, there is still friction and collision between the materials and between the materials and the sparse teeth 114, achieving continuous loosening; the loose and fluffy material is uniformly discharged from the bottom discharge port 112. In this embodiment, the dispersion process and the conveying and sliding process are integrated in space, and the process is compact and efficient. The movement of the material in the cavity is all used for dispersion purposes, and the energy utilization rate is high.

[0033] In one embodiment, as shown in Figure 1 , Figure 2 The roller 120 is provided with comb-shaped protrusions, and the roller 120 can engage with the sparse teeth 114 on the inner wall of the dispersion cavity. When the roller 120 rotates, the comb-shaped protrusions thereon and the sparse teeth 114 fixed on the inner wall of the cavity form two interlaced combs to generate shear force instead of extrusion force. Traditional roller pressing mainly relies on pressure to deform and break the material, and has limited effect on tough and tightly wound tobacco groups or adhered cut tobacco. The tooth engagement generates strong shear force, which can directly cut the fiber connection like scissors. For mutually curled and entangled tobacco, the separation efficiency of shear action is much higher than that of simple roller pressing or combing. For groups of cut tobacco adhered together due to moisture or processing, shear force can also forcibly tear the adhered interface to achieve effective separation.

[0034] The roller 120 and the combs on the inner wall cover the entire contact surface, forming a dense shear network. When the material passes through this area, it will be subjected to multi-point and continuous shear action, thereby rapidly and uniformly breaking the large material into smaller units, ensuring that the discharged material is extremely loose and fluffy, with almost no large groups or entanglements. Even a small amount of material that is not directly roller-pressed by the roller 120 will be sheared in the gap between the sparse teeth 114 and the protrusions during the sliding process.

[0035] Furthermore, the rotation and raised structure of roller 120, like a screw or auger, actively pushes material toward the center and bottom of the dispersion chamber, accelerating its flow. The powerful shearing and pushing action instantly processes incoming material, preventing it from accumulating near feed inlet 111 or in front of roller 120 and causing blockage. In conjunction with the aforementioned embodiment, the pushing action of roller 120 interacts with the gravity-guided sliding of the inverted conical inner wall, forming a highly efficient cycle for material conveying, dispersion, and discharge.

[0036] In this embodiment, a drive member 113 is provided on the exterior of the housing 110 to drive the roller 120 to rotate. The drive member 113 can be configured arbitrarily based on practical circumstances and is not limited herein. For example, the drive member 113 includes a motor and a belt. A driving pulley is provided on the output shaft of the motor. A driven pulley is provided at the end of the rotating shaft of the roller 120 extending outside the housing 110. The belt is disposed between the driving pulley and the driven pulley. The motor drives the roller 120 to rotate via the belt.

[0037] In one embodiment, for example, Figure 1 、 Figure 2 As shown, the cut-stem separation device includes a frame 400, on which a conveyor belt 210 is mounted. One of the conveyor belts 210 is located between the dispersion chamber and the air separation element 230 to transport the tobacco stems and cut tobacco from the dispersion chamber into the air separation element 230. The frame 400 is the skeleton of the entire cut-stem separation device, providing support for the dispersion assembly 100, the conveyor assembly 200, the air separation element 230, and the like. The vibrating element 220 on the conveyor belt 210 generates continuous vibration during operation. Reliable support can effectively absorb and disperse this vibration energy, preventing vibration transmission from causing other components to loosen, shift, or generate noise, thereby ensuring the smooth and accurate operation of the equipment. Furthermore, the frame 400 ensures that the discharge port 112 of the dispersion chamber, the conveyor belt 210, and the feed port 111 of the air separation element 230 remain precisely aligned during installation and operation, preventing material spillage or poor conveying.

[0038] The dispersion assembly 100, conveying assembly 200, and air filter 230 can be installed and debugged separately as independent modules on the frame 400, simplifying the overall equipment assembly process. When a component requires repair or replacement, it can be conveniently removed and replaced on the frame 400 without disassembling the entire equipment, reducing downtime and lowering maintenance costs. Furthermore, the frame 400 can be mass-produced as a standard component, allowing for flexible combination of different functional modules, facilitating serialized and standardized manufacturing of the equipment.

[0039] The conveyor belt 210, located between the dispersion chamber and the air separation element 230, continuously and evenly receives the loosened mixture of tobacco stems and shredded tobacco from the dispersion chamber outlet 112 and smoothly conveys it to the feed area of ​​the air separation element 230. During the conveying process, the vibrating element 220 on the conveyor belt 210 continuously operates to further prevent the material from re-aggregating or compacting during movement, ensuring that the material enters the air separation area in an optimally loose state, maximizing air separation efficiency.

[0040] In one embodiment, for example, Figure 1 、 Figure 2 As shown, a conveyor belt 210 is positioned on the side of the air separation element 230 away from the dispersion chamber. One end of the conveyor belt 210 is positioned at the discharge point of the air separation element 230, and the end of the conveyor belt 210 away from the air separation element 230 extends to the storage area. After the air separation element 230 completes separation, the heavier tobacco stems fall through the discharge port 112 below it. The conveyor belt 210 directly receives these tobacco stems, eliminating the tedious manual steps of receiving and transporting the stems. This automates the entire process from separation to collection, eliminating the need for operators to be on duty near the discharge port 112, reducing labor intensity and improving production efficiency.

[0041] Without the conveyor belt 210 beneath the air separation element 230 to promptly remove the tobacco stems, they would accumulate at the discharge port 112. This could block the discharge port 112 and cause pressure imbalance within the air separation element 230, severely impacting the air separation process and potentially even forcing the entire production line to shut down. The conveyor belt 210 continuously removes product, ensuring that the discharge port 112 of the air separation element 230 remains unobstructed, ensuring the continuous and stable operation of the entire separation process.

[0042] In one embodiment, for example, Figure 1 、 Figure 2 As shown, the vibrating member 220 is disposed between the conveyor belt 210 and the frame 400. The vibrating member 220 includes a fixed portion and a vibrating portion. The fixed portion is mounted on the frame 400, and the vibrating portion is mounted on the fixed portion and abuts against the conveyor belt 210, thereby driving the conveyor belt 210 to vibrate in a direction perpendicular to the conveying direction. The vibrating portion directly abuts the supporting surface, rollers, or support plate of the conveyor belt 210, transmitting the vibration energy directly to the conveyor belt 210, thereby reducing vibration transmission losses. This direct contact transmission method also ensures that the conveyor belt 210 can vibrate at a preset amplitude and frequency, ensuring the vibration separation effect.

[0043] The fixed part of the vibrating member 220 is firmly mounted on the frame 400 which is the overall support, providing a very stable support for the vibration source. The vibrating member 220 generates reaction forces when it is in operation. Being fixed on the firm frame 400, these forces can be effectively resisted, preventing the vibrating member 220 from loosening, shifting or being damaged by itself. In addition, in this embodiment, such arrangement also helps to concentrate the vibration in the area of the conveying belt 210, avoiding unnecessary vibration from being transmitted to other parts of the frame 400 or the connected dispersion chamber, the air separation member 230, and protecting other components.

[0044] As for the vibration direction, the vibration is in the direction perpendicular to the conveying direction, which can effectively shake and shake the material on the conveying belt 210, separate the tobacco strands that are intertwined with each other, and break the clumps, and also help the material to automatically spread in the width direction of the conveying belt 210, preventing uneven load.

[0045] In one embodiment, as shown in Figure 1 , Figure 2 The frame 400 is provided with steps, and the conveying belt 210, the housing 110 and the air separation member 230 are arranged on different steps, so that the housing 110, the conveying belt 210, the air separation member 230 and the other conveying belt 210 are arranged in the vertical direction from high to low. The material has mass and will naturally move from high to low under the action of gravity. Arranged in the vertical direction, the material falling from the discharge port 112 of the dispersion chamber can directly rely on gravity to fall into the first section of the conveying belt 210 below. Similarly, the tobacco stems falling from the discharge port 112 of the air separation member 230 can also rely on gravity to fall into the second section of the conveying belt 210 below. This reduces the need for mechanical lifting or forced pushing, reduces the energy consumption of the conveying system, and achieves energy-saving operation. It also avoids setting up complex lifting devices or pressurized conveying mechanisms at these links, making the equipment structure simpler and more reliable.

[0046] In this embodiment, the stepped layout makes the transfer path of the material from one process to the next natural and smooth. The action of gravity can actively pull the material to move downward, effectively preventing the material from being retained, accumulated or blocked at the connection of the equipment.

[0047] In one embodiment, as shown in Figure 1 , Figure 2As shown, the cut stem separation device includes a visual detection assembly 300, which includes a processor 310 and a detection head 320 in data connection with the processor 310. The detection head 320 is arranged above the conveying belt 210 in the vertical direction and is used to detect the separation of the tobacco stems and tobacco shreds on the conveying belt 210. The detection head 320 performs non-destructive and continuous visual scanning on the materials on the conveying belt 210 from above without interfering with the normal material flow and separation process. The detection head 320 is directly in data connection with the processor 310 and can obtain the separation state of the tobacco stems and tobacco shreds after the winnowing or during the conveying process in real time, such as the shred content in the tobacco stems and the stem content in the tobacco shreds. In addition, through image detection, it can also be determined whether the materials are evenly spread on the conveying belt 210. The visual detection assembly 300 of the embodiment can replace the conventional manual sampling and naked-eye observation mode and detect more objectively, comprehensively, and timely.

[0048] The processor 310 can analyze the detected images and accurately calculate key quality indicators such as the impurity content. When the separation effect is detected to be out of the preset qualified range, such as the tobacco stem shred content being too high, the processor 310 can connect other alarm-related components and issue an audible and visual alarm to remind the operator to intervene in time. It is ensured that the tobacco stems and tobacco shreds entering the next process meet the quality standards and that the cigarette quality problems caused by poor separation are eliminated from the source.

[0049] In one embodiment, as shown in Figure 1 , Figure 2 As shown, at least one detection head 320 is arranged above each conveying belt 210, and each detection head 320 is in data connection with the processor 310. Through the cooperation of multiple detection heads 320, the materials on the conveying belt 210 can be detected in more detail. For example, the detection head 320 located behind the dispersion cavity and in front of the winnowing element 230 can monitor the material state after being preprocessed by being dispersed and vibrated in real time and detect whether the material is sufficiently loose and whether there are large groups or entanglements. If the preprocessing effect is not good, the processor 310 can immediately issue a warning, and the processor 310 can also be in electrical connection with the control part of the conveying belt 210 and the vibration element 220 to adjust the roller 120 rotation speed or vibration intensity in advance to prevent the problem from worsening and to avoid unqualified materials entering the winnowing link.

[0050] The detection head 320 located behind the winnowing element 230 is responsible for the final quality control. It accurately detects the amount of tobacco shreds mixed in the tobacco stems and confirms whether the separation result meets the standards, forming a closed loop with the source monitoring.

[0051] The embodiment also provides a tobacco leaf processing equipment, which includes a tobacco leaf preprocessing device and the cut stem separation device in any one of the above embodiments. The tobacco leaf preprocessing device processes the tobacco leaves and then conveys the processed tobacco leaves to the cut stem separation device for separation of the tobacco stems and tobacco shreds.

[0052] The tobacco leaf processing equipment of the embodiment includes the stem and shred separating device in any one of the above-mentioned embodiments, and has all the beneficial effects of the stem and shred separating device, which will not be described here again.

[0053] It should be noted that the features in the embodiments of the present application can be combined with each other without conflict.

[0054] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Various modifications and changes can be made by those skilled in the art based on the spirit and principles of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
