Description

Technical Field

[0001] This utility model relates to the field of tobacco processing technology, and in particular to a tobacco shred dispersing device. Background Technology

[0002] Dispersing tobacco shreds to prevent clumping is a crucial step in tobacco processing. It plays an important role in improving the uniformity of tobacco shreds, optimizing blending effects, enhancing combustion performance, and adapting to the process requirements of high-speed continuous production.

[0003] In existing technologies, the main methods for dispersing tobacco shreds include mechanical dispersing and airflow loosening. The former mainly uses mechanical vibrating screens or drum loosening equipment with internal rakes to disperse tobacco shreds through physical contact, i.e., contact mechanical action. This method has drawbacks such as mechanical damage to the tobacco shreds and wear and tear on components due to long-term friction. The latter is mainly based on pneumatic action for loosening, usually using unidirectional airflow. This method is prone to problems such as localized tobacco shred aggregation caused by unidirectional airflow movement, poor dispersion effect due to excessively strong or weak airflow, and excessive energy consumption. Utility Model Content

[0004] In view of this, the purpose of this utility model is to overcome the shortcomings in related technologies, and this utility model provides a tobacco shred separation device.

[0005] This utility model provides the following technical solution: A tobacco shred dispersing device includes a dispersing cylinder and a mixing component.

[0006] The upper end of the discrete cylinder is provided with a feed inlet, and the lower end of the discrete cylinder is provided with a discharge outlet. An air conveying section is provided on the side wall of the discrete cylinder, which is connected to an air pump to generate an airflow that rotates relative to the axis of the discrete cylinder within the cylinder. A mixing assembly is disposed on the discrete cylinder, comprising a first discrete disk, a second discrete disk, and a rotating shaft. The rotating shaft is vertically inserted into the discrete cylinder. The first and second discrete disks are sequentially fixedly sleeved on the rotating shaft along the direction from the feed inlet to the discharge outlet. The rotating shaft is connected to a driving device. The driving device drives the rotating shaft to rotate in the opposite direction to the rotation direction of the rotating airflow generated within the discrete cylinder.

[0007] As a further improvement to the above technical solution, the rotating airflow generated by the gas delivery section in the discrete cylinder is located between the first discrete disk and the second discrete disk.

[0008] As a further improvement to the above technical solution, the sidewall of the discrete cylinder is provided with a plurality of air supply holes evenly distributed along its circumference. The opening direction of the air supply holes is set at an angle to the radial direction of the discrete cylinder, and the plurality of air supply holes together form the air supply section. The setting height of the air supply holes is located between the first discrete disk and the second discrete disk.

[0009] As a further improvement to the above technical solution, the first discrete disk is recessed in the direction away from the feed inlet, and the lowest point of the first discrete disk is assembled and connected to the rotating shaft; the second discrete disk is protruded in the direction close to the feed inlet, and the highest point of the second discrete disk is assembled and connected to the rotating shaft.

[0010] As a further improvement to the above technical solution, a guide groove is provided extending from the highest point of the second discrete disk to the edge of the second discrete disk, and the guide grooves are evenly distributed circumferentially relative to the axis of the rotating shaft.

[0011] As a further improvement to the above technical solution, the guide groove is arc-shaped and offset along the circumferential direction of the rotating shaft.

[0012] As a further improvement to the above technical solution, the offset direction of the guide groove is the same as the rotation direction of the rotating shaft.

[0013] As a further improvement to the above technical solution, the tobacco shred dispersing device also includes a base frame, the dispersing cylinder is mounted on the base frame, and a vibrator is mounted on the base frame.

[0014] As a further improvement to the above technical solution, the base frame is provided with a spiral guide trough, the center of which is located below the discharge port.

[0015] As a further improvement to the above technical solution, the bottom of the guide trough gradually rises from the center position towards the outlet direction.

[0016] Compared with related technologies, the beneficial effects of this utility model are: The tobacco shred discrepancies device provided by this utility model operates as follows when processing tobacco shreds to be discrepancies: First, the operator starts the drive device, thereby causing the rotating shaft to start rotating. The rotation of the rotating shaft drives the first and second discrepancies disks connected to it to rotate synchronously.

[0017] At the same time, the air pump is activated. The air pump delivers airflow into the discretization cylinder through the air delivery section, creating a rotating airflow inside the discretization cylinder that runs in the opposite direction to the rotation of the shaft. This reverse airflow design adds extra power and effect to the discretization process of the tobacco.

[0018] After the above preparations are completed, the operator puts the tobacco shreds to be dispersed into the feed port above the dispersion cylinder. After entering the dispersion cylinder, the tobacco shreds will first fall onto the high-speed rotating first dispersion disc. Under the centrifugal force of the first dispersion disc, the tobacco shreds are quickly loosened and gradually slide off the edge of the first dispersion disc.

[0019] The loosened tobacco then continues to fall onto the second disc. Similar to the first disc, the second disc also uses the centrifugal force generated by its rotation to further loosen the tobacco. The tobacco undergoes another centrifugal loosening process on the second disc and eventually slides off its edge.

[0020] It is worth noting that as the tobacco falls from the first disc to the second disc, it is significantly affected by the previously input rotating airflow. Because the tobacco rotates as it falls from the first disc, and its rotation direction is opposite to that of the airflow, a pulling effect is created between them. This pulling effect not only enhances the looseness of the tobacco but also prevents damage to it.

[0021] Compared to existing mechanical loosening methods, the tobacco shred dispersion device of this invention effectively avoids potential damage to the tobacco shreds caused by mechanical force. Furthermore, compared to unidirectional airflow conveying, this device, through its reverse-rotating airflow design, successfully solves the problems of localized tobacco shred aggregation caused by unidirectional airflow movement, as well as poor dispersion effects due to excessively strong or weak airflow. In addition, this device significantly reduces energy consumption and improves energy utilization efficiency.

[0022] In summary, this utility model's tobacco shred dispersing device, through its unique working principle and design, achieves efficient and non-destructive loosening of tobacco shreds. This innovation not only greatly improves the quality of tobacco shred dispersing but also significantly increases the dispersing speed.

[0032] Combination Figure 1 , Figure 2 As shown, an embodiment of this utility model provides a tobacco shred dispersing device, including a dispersing cylinder 100 and a mixing assembly 200.

[0033] The upper end of the discrete cylinder 100 is provided with a feed inlet 110, and the lower end of the discrete cylinder 100 is provided with a discharge outlet 120; the side wall of the discrete cylinder 100 is provided with a gas conveying section 130, such as... Figure 3 As shown, the gas delivery unit 130 is connected to a gas pump device to generate an airflow that rotates relative to the axis of the discrete cylinder 100 within the discrete cylinder 100; the mixing assembly 200 is disposed on the discrete cylinder 100, and the mixing assembly 200 includes a first discrete disk 210, a second discrete disk 220, and a rotating shaft 230. The rotating shaft 230 is vertically inserted into the discrete cylinder 100. The first discrete disk 210 and the second discrete disk 220 are sequentially fixedly sleeved on the rotating shaft 230 along the direction from the feed inlet 110 to the discharge outlet 120. The rotating shaft 230 is connected to a driving device for transmission; the driving device drives the rotating shaft 230 to rotate in the opposite direction to the rotation direction of the rotating airflow generated within the discrete cylinder 100.

[0034] The tobacco shred discretization device provided in this embodiment operates as follows when processing tobacco shreds to be discretized: First, the operator starts the drive device, thereby causing the rotating shaft 230 to start rotating. The rotation of the rotating shaft 230 drives the first discretization disk 210 and the second discretization disk 220 connected to it to rotate synchronously.

[0035] At the same time, the air pump is started. The air pump inputs airflow into the discretization cylinder 100 through the air delivery section 130, forming a rotating airflow in the discretization cylinder 100 that is opposite to the rotation direction of the rotating shaft 230. This reverse airflow design adds extra power and effect to the discretization process of tobacco.

[0036] After the above preparations are completed, the operator puts the tobacco to be dispersed into the feed port 110 above the dispersion cylinder 100. After entering the dispersion cylinder 100, the tobacco will first fall onto the high-speed rotating first dispersion disk 210. Under the centrifugal force of the first dispersion disk 210, the tobacco is quickly loosened and gradually slides off the edge of the first dispersion disk 210.

[0037] Subsequently, the loosened tobacco continues to fall onto the second disc 220. Similar to the first disc 210, the second disc 220 also uses the centrifugal force generated by its rotation to further loosen the tobacco. The tobacco undergoes another centrifugal loosening process on the second disc 220 and eventually slides off the edge of the second disc 220.

[0038] It is worth noting that as the tobacco falls from the first discrete disk 210 onto the second discrete disk 220, it is significantly affected by the previously input rotating airflow. Because the tobacco rotates as it falls from the first discrete disk 210, and its rotation direction is opposite to that of the rotating airflow, a pulling effect is generated between them. This pulling effect not only enhances the loosening effect of the tobacco but also prevents damage to it.

[0039] In some specific embodiments, the rotating airflow generated by the gas delivery section 130 in the discrete cylinder 100 is located between the first discrete disk 210 and the second discrete disk 220; this arrangement places the rotating airflow in this specific space, which can achieve layered processing of the first discrete disk 210, the second discrete disk 220 and the rotating effect of the rotating airflow on the tobacco.

[0040] Specifically, the first discrete disk 210 and the second discrete disk 220 apply centrifugal force to the tobacco shreds in their respective rotational modes, causing them to rotate; while the rotating airflow applies force to the tobacco shreds from another dimension, causing the tobacco shreds to rotate under the influence of the airflow. By confining the rotating airflow between the two discrete disks, the mutual influence and cancellation between the centrifugal force generated by the rotation of the first discrete disk 210 and the second discrete disk 220 and the force exerted by the rotating airflow on the tobacco shreds can be effectively reduced.

[0041] In this way, the discrete effects of the first discrete disk 210, the second discrete disk 220, and the rotating airflow on the tobacco can be exerted more independently and fully, avoiding the problem of poor discrete effect caused by the mutual interference of different forces. This facilitates further improvement in the discrete processing effect of the tobacco, enabling the tobacco to be discrete more uniformly and efficiently.

[0042] In some specific embodiments, the sidewall of the discretization cylinder 100 is provided with a plurality of air inlets 131 evenly distributed along its circumference. The opening direction of the air inlets 131 is set at an angle to the radial direction of the discretization cylinder 100, and the plurality of air inlets 131 together form the air supply section 130. The height of the air inlets 131 is located between the first discretization disk 210 and the second discretization disk 220. When the airflow enters from the air inlets 131, it will form a regular rotating airflow in the space between the first discretization disk 210 and the second discretization disk 220. This stable and reliable rotating airflow is crucial for the discretization of tobacco shreds. It can cooperate with the centrifugal force of the first discretization disk 210 and the second discretization disk 220 to apply force to the tobacco shreds from different directions, so that the tobacco shreds are fully and uniformly discretized in the discretization cylinder 100, thereby ensuring that the discretization effect of the tobacco shreds reaches the optimal state.

[0043] In some specific embodiments, the first disc 210 is recessed in the direction away from the feed inlet 110, and the lowest point of the first disc 210 is assembled and connected to the rotating shaft 230; the second disc 220 is protruded in the direction close to the feed inlet 110, and the highest point of the second disc 220 is assembled and connected to the rotating shaft 230. This is mainly to prevent the tobacco from falling into the central area of ​​the second disc 220 under the action of the rotating airflow, thus avoiding material accumulation. Because once the material accumulates in the center, it will not only affect the dispersion effect of the tobacco, but may also cause problems such as equipment malfunction.

[0044] Specifically, during the tobacco processing, when the tobacco enters the discrepancies cylinder 100 through the feed inlet 110, it first falls onto the first discrepancies disk 210. Because the clumps of tobacco are relatively heavy, they will preferentially fall to the center of the first discrepancies disk 210 under the influence of gravity. After the first discrepancies disk 210 begins to rotate, these clumps of tobacco will gradually be dispersed into filaments under the combined influence of the rotation of the first discrepancies disk 210 and their own gravity, and will gradually move away from the central area as the first discrepancies disk 210 rotates.

[0045] Meanwhile, tobacco shreds that are not clumped together or have small clumps are directly thrown out of the first disc 210 by the strong centrifugal force generated by its high-speed rotation. These thrown-out tobacco shreds, in a rotating state, will encounter the rotating airflow in the opposite direction within the disc 100. The rotating airflow will pull on the rotating tobacco shreds, further dispersing them and making them more loose and uniform. The tobacco shreds that have undergone this process will eventually fall onto the second disc 220.

[0046] The tobacco shreds falling onto the second disc 220 are centrifugally dispersed as the disc rotates. The raised structure of the second disc 220 and the centrifugal force generated by its rotation further disperse and refine the tobacco shreds. Finally, the fully dispersed tobacco shreds fall from the edge of the second disc 220 and are eventually discharged from the disc cassette 100.

[0047] By performing such layered and meticulous discrete processing on tobacco shreds, the tobacco shreds can be processed from multiple stages and different angles, effectively avoiding problems such as uneven dispersion and local accumulation that may occur in traditional processing methods. This facilitates further improvement in the discrete processing effect of tobacco shreds, resulting in a significant improvement in the quality of tobacco shreds.

[0048] like Figure 4 As shown, in some specific embodiments, a guide groove 221 extends from the highest point of the second discrete disk 220 to its edge. The guide grooves 221 are evenly distributed circumferentially relative to the axis of the rotating shaft 230. This arrangement of the guide grooves 221 is significant because during the tobacco discrepancies processing, when the tobacco falls onto the second discrete disk 220, the guide grooves 221 can significantly increase the friction between the upper surface of the second discrete disk 220 and the tobacco. Since the tobacco's state is complex after entering the discrepancies cylinder 100, it may clump or become entangled. If the friction is insufficient when it contacts the second discrete disk 220, the tobacco may slide on the disk surface and not be fully subjected to the centrifugal force generated by the rotation of the disc, resulting in poor discrepancies.

[0049] The presence of the guide groove 221 alters the upper surface structure of the second discrete disk 220, increasing the roughness of the contact between the tobacco and the disk surface, thereby increasing friction. When the second discrete disk 220 begins to rotate, the greater friction allows the tobacco to rotate better with the disk, rather than slipping on the surface. This results in a stronger centrifugal force acting on the tobacco during rotation, enabling it to disperse more quickly.

[0050] Meanwhile, the guide groove 221 can also guide the movement of the tobacco to a certain extent, making the movement of the tobacco on the second discriminating disk 220 more orderly and avoiding local accumulation or chaos. Through these functions, when the second discriminating disk 220 comes into contact with the tobacco, it can accelerate the discriminating speed of the tobacco.

[0051] In some specific embodiments, the guide groove 221 is arc-shaped and offset along the circumferential direction of the rotating shaft 230, which facilitates further improvement of the resistance of the second discrete disk 220 to the centrifugal motion of the tobacco, and further improves the dispersion effect of the tobacco after it falls on the second discrete disk 220.

[0052] In some specific embodiments, the offset direction of the guide groove 221 is the same as the rotation direction of the rotating shaft 230, so that the tobacco falling on the second discrete disk 220 is uniformly and quickly thrown out in the circumferential direction in an arc parabolic path under the guidance of the guide groove 221, reducing the probability of clogging during the discharge of tobacco from the discrete cylinder 100 and ensuring the reliability of this embodiment.

[0053] In some specific embodiments, the tobacco shred dispersing device further includes a base frame 300, on which the dispersing cylinder 100 is mounted. A vibrator is installed on the base frame 300. When the vibrator is activated, it vibrates regularly according to a preset frequency and amplitude. This vibrational energy is rapidly transmitted to the dispersing cylinder 100 through the base frame 300, causing the dispersing cylinder 100 to vibrate accordingly. Furthermore, the first dispersing disk 210 and the second dispersing disk 220 in the mixing assembly 200, which are closely related to the tobacco shred dispersing process, also vibrate synchronously under the influence of the dispersing cylinder 100 due to their assembly relationship with it.

[0054] The vibration of the first discretizing disk 210 and the second discretizing disk 220 plays a crucial role in the loosening of tobacco shreds. In traditional discretizing processes, relying solely on the centrifugal force generated by the rotation of the discretizing disks to disperse the tobacco shreds may not be ideal for some severely clumped or densely textured tobacco shreds. However, when the first discretizing disk 210 and the second discretizing disk 220 begin to vibrate, the energy generated by the vibration acts on the tobacco shreds in multiple ways. On the one hand, the vibration disrupts the binding force between the tobacco shreds, causing the clumped tobacco shreds to gradually loosen; on the other hand, the vibration also makes the movement of the tobacco shreds on the discretizing disks more intense and complex, increasing the opportunities for collision and friction between the tobacco shreds and the discretizing disks, as well as other tobacco shreds, thereby further dispersing the tobacco shreds into finer filaments.

[0055] By activating a vibrator to drive the first discrete disk 210 and the second discrete disk 220 of the dispersion cylinder 100 and the mixing assembly 200 to vibrate, a multi-dimensional dispersion processing mode is formed by combining this with a simple rotational dispersion method. This mode can act on the tobacco shreds entering the dispersion cylinder 100 from different angles and in different ways, thereby significantly improving the loosening effect of the tobacco shreds, making the processed tobacco shreds more uniform and loose, and meeting the quality requirements of subsequent production processes.

[0056] In some specific embodiments, the base frame 300 is provided with a spiral guide trough 310, the center of which is located below the discharge port 120. When the discretization cylinder 100 completes the discretization of the tobacco shreds, the tobacco shreds material can fall directly into the guide trough 310 when discharged from the discharge port 120, avoiding the material from scattering to other parts of the equipment or the surrounding ground, and ensuring the accuracy and integrity of material collection.

[0057] The spiral-shaped feed chute 310 has unique design advantages. Its spiral shape gives the feed chute 310 a certain length and continuity, providing a stable path for material movement. When the tobacco material falls into the feed chute 310, the vibration generated by the vibrator installed on the base frame 300 is transmitted to the feed chute 310 and the material inside. Under the influence of vibration, the material will not accumulate in one place in the feed chute 310, but will be automatically spread out. The localized material accumulation that might have occurred due to uneven discharge is improved by the vibration, and the material is evenly distributed across the cross-section of the feed chute 310.

[0058] Simultaneously, the vibration also causes the material to move automatically along the spiral guide chute 310. Driven by the energy generated by the vibration, the material gradually moves towards the outlet along the spiral trajectory of the guide chute 310, and is finally discharged from the end of the guide chute 310. This process eliminates the need for operators to manually level or push the material, greatly reducing the workload of the operators.

[0059] For operators, this design makes receiving and transferring tobacco materials extremely convenient. They simply need to place a suitable receiving container at the end of the feed chute 310 to easily collect the processed and automatically discharged tobacco materials. Compared to traditional material receiving methods, there is no need to frequently clean up scattered materials or manually adjust their position, saving a significant amount of time and effort.

[0060] In some specific embodiments, the bottom of the feed trough 310 gradually rises from the center towards the outlet. After the tobacco material falls into the feed trough 310, it will move within the trough due to factors such as vibration from the vibrator. As the bottom of the trough gradually rises from the center towards the outlet, the tobacco needs to overcome the gravitational component generated by the rise in the bottom of the trough during its movement, which is equivalent to increasing the resistance to movement of the tobacco within the feed trough 310.

[0061] If the bottom of the feed trough 310 is horizontal, the tobacco shreds may move towards the outlet relatively quickly and disorderly under the action of vibration. This may result in some tobacco shreds reaching the outlet first, while others have not moved sufficiently, leading to uneven distribution of tobacco material from the outlet. There may be a period of time when more tobacco shreds are discharged, and another period of time when less tobacco shreds are discharged.

[0062] By adopting a design with a gradually rising bottom, the increased resistance to movement results in a more stable and uniform movement speed of the tobacco shreds within the feed trough 310. The tobacco shreds will not rush towards the outlet due to vibration, but will move forward at a more consistent rhythm under the constraint of the gradually rising bottom. This ensures that when the tobacco material is discharged from the outlet of the feed trough 310, the quantity and distribution of the discharged tobacco shreds are more uniform, preventing material accumulation or flow interruptions.
