[0019] This design completely solves the cumbersome problem of needing to replace the screen or step-by-step operation multiple times in the traditional screening method, significantly improving the screening efficiency. In the tobacco processing workshop, the traditional screening equipment often needs manual intervention, frequent shutdown to replace the screen or adjust the equipment, resulting in low production efficiency, while the multi-stage cut stem separator of the present application realizes continuous and automated screening through the cooperative work of multi-stage screens, greatly reducing manual intervention and downtime. In addition, the design of the decreasing aperture of the first screen, the second screen and the third screen enables the cut stem to be separated step by step in the screening process from top to bottom, ensuring that each specification of cut stem can be accurately screened, avoiding cut stem mixing and waste. This efficient and accurate screening method is particularly suitable for scenarios with high requirements for cut stem classification in the tobacco processing workshop, and can significantly improve production efficiency and product quality. At the same time, the structure of the equipment is compact, the floor space is small, the equipment cost and workshop space occupation are reduced, providing higher economic benefits and operational convenience for tobacco processing enterprises.
[0020] 2. As a preferred embodiment of the present application, the installation and removal of the first screen are more convenient through the plug-in cooperation of the first limiting shaft and the first limiting hole, which facilitates maintenance and replacement of the screen. This design is particularly suitable for environments with frequent maintenance of equipment in tobacco processing workshops, can reduce downtime and improve production efficiency. In traditional screening equipment, the replacement of the screen usually requires the disassembly of multiple components, which is complex and time-consuming. However, the design of the present application makes the replacement of the screen simple and fast, and the operator only needs to insert the first limiting shaft into the first limiting hole to complete the installation without the need for additional tools or complex operations. This convenience not only improves the maintenance efficiency of the equipment, but also reduces the labor intensity of the operators, and is particularly suitable for high-intensity and long-time running environments in tobacco processing workshops. In addition, the plug-in cooperation design also enhances the stability of the screen, preventing it from shifting or loosening during vibration, ensuring the continuity and reliability of the screening process. And the multiple first limiting shafts and first limiting holes arranged at intervals improve the installation stability of the first screen.
[0021] 3. As a preferred embodiment of the present application, the design of the first connecting rod makes the vibration of the first screen more stable and efficient, which can ensure the screening effect of the flaky cut stem. In tobacco processing workshops, such stable vibration screening can effectively reduce the blockage of cut stem and improve the screening precision. The design of the present application simplifies the transmission structure through the direct connection of the first connecting rod and the first driving mechanism, improving the stability and reliability of the vibration. In addition, the reciprocating motion design of the first connecting rod makes the vibration of the screen more uniform, which can effectively avoid the accumulation or blockage of cut stem on the screen, ensuring the continuity and efficiency of the screening process.
[0022] 4. As a preferred embodiment of the present application, the design of the limiting convex part further enhances the stability of the first screen, preventing it from shifting or loosening during vibration, ensuring the continuity and reliability of the screening process. In traditional screening equipment, the screen is prone to shift due to component loosening or wear during vibration, affecting the screening effect. However, the design of the present application sets a limiting convex part on the limiting shaft, so that the screen can always remain stable during vibration, avoiding shifting or loosening caused by vibration. This design is particularly suitable for high-intensity and long-time running environments in tobacco processing workshops, which can significantly improve the service life and production efficiency of the equipment.
[0023] 5. As a preferred embodiment of the present application, the rotation design of the first frame body and the cooperation of the first locking member enable the first screen to adjust the inclination angle as needed, facilitating the cleaning of residual stems on the first screen or the replacement of the screen. Through the rotation of the first frame body and the cooperation of the first locking member, the operator can quickly adjust the inclination angle of the first screen, facilitating the cleaning of residual stems or the replacement of the first screen without disassembling the equipment or stopping operation. This design significantly improves the maintenance efficiency and operation convenience of the equipment, and is particularly suitable for high-intensity and long-time running environments in tobacco processing workshops. In addition, the design of the first locking member also enhances the stability of the equipment, preventing accidental inclination of the first screen during vibration, ensuring the continuity and reliability of the screening process.

[0050] The multi-stage cut stem separator of the present application can complete the efficient screening of sheet cut stem, granular cut stem and filamentous cut stem at one time by integrating the first screen 2, the second screen 3 and the third screen 4 in the same device and being equipped with independent first driving mechanism 5, second driving mechanism 6 and third driving mechanism 7. When screening, the cut stem is fed to the first screen 2 by the feeding unit, the first driving mechanism 5 drives the first screen 2 to vibrate, the granular cut stem and filamentous cut stem with smaller size in the cut stem fall through the first screening hole 21 to the second screen 3 below under the action of vibration, the sheet cut stem with larger size cannot pass through the first screening hole 21 and stays on the first screen 2, thus realizing the screening of sheet cut stem; the second driving mechanism 6 drives the second screen 3 to vibrate, the filamentous cut stem with smaller size in the cut stem falls through the second screening hole 31 to the third screen 4 below under the action of vibration, the granular cut stem with relatively larger size cannot pass through the second screening hole 31 and stays on the second screen 3, thus realizing the screening of granular cut stem; the third driving mechanism 7 drives the third screen 4 to vibrate, the debris and the like mixed in the cut stem are screened by the third screen 4 under the action of vibration, the filamentous cut stem with relatively larger size cannot pass through the third screening hole 41 and stays on the third screen 4, thus realizing the screening of filamentous cut stem.
[0051] This design completely solves the cumbersome problem of needing to replace the screen or step-by-step operation multiple times in the traditional screening method, significantly improving the screening efficiency. In the tobacco processing workshop, the traditional screening equipment often needs manual intervention, frequent shutdown to replace the screen or adjust the equipment, resulting in low production efficiency, while the multi-stage cut stem separator of the present application realizes continuous and automated screening through the cooperative work of the multi-stage screens, greatly reducing manual intervention and downtime. In addition, the design of the gradually decreasing aperture of the first screen 2, the second screen 3 and the third screen 4 enables the cut stem to be separated step by step in the screening process from top to bottom, ensuring that each specification of cut stem can be accurately screened, avoiding cut stem mixing and waste. This efficient and accurate screening method is particularly suitable for scenarios with high requirements for cut stem classification in the tobacco processing workshop, which can significantly improve production efficiency and product quality.

[0052] Preferably, 5mm < D1 < 10mm, 2mm < D2 < 5mm, 0.5mm < D1 < 2mm.
[0053] As a preferred embodiment of the present application, the rack 1 comprises two pairs of first frame bodies 1, and the first screen 2 is located between the two first frame bodies 1. The first frame body 1 is provided with a plurality of first limiting insertion holes 111, and the first screen 2 is provided with a plurality of first limiting insertion shafts 22 on the side portions. The first screen 2 is installed on the first frame body 1 through the insertion fit of the first limiting insertion shaft 22 and the first limiting insertion hole 111.
[0054] Through the insertion fit of the first limiting insertion shaft 22 and the first limiting insertion hole 111, the installation and disassembly of the first screen 2 are more convenient, which is convenient for maintenance and replacement of the screen. This design is particularly suitable for the environment of frequent maintenance of equipment in the tobacco processing workshop, which can reduce downtime and improve production efficiency. In traditional screening equipment, the replacement of the screen usually requires the disassembly of multiple components, which is complex and time-consuming. However, the design of the present application makes the replacement of the screen simple and fast. The operator only needs to insert the first limiting insertion shaft 22 into the first limiting insertion hole 111 to complete the installation without the need for additional tools or complex operations. This convenience not only improves the maintenance efficiency of the equipment, but also reduces the labor intensity of the operator, which is particularly suitable for the environment of high-intensity and long-time operation in the tobacco processing workshop. In addition, the design of the insertion fit also enhances the stability of the screen, preventing it from shifting or loosening during vibration, ensuring the continuity and reliability of the screening process. Moreover, the plurality of first limiting insertion shafts 22 and first limiting insertion holes 111 arranged at intervals improve the installation stability of the first screen 2.
[0055] As a preferred embodiment of the present embodiment, one of the plurality of first limiting insertion shafts 22 is a first connecting rod 120, and the output shaft of the first driving mechanism 5 is connected to the first connecting rod 120. The first driving mechanism 5 drives the first connecting rod 120 to reciprocate to drive the first screen 2 to vibrate.
[0056] The design of the first connecting rod 120 makes the vibration of the first screen 2 more stable and efficient, which can ensure the screening effect of the sheet tobacco. In the tobacco processing workshop, such stable vibration screening can effectively reduce the blockage of tobacco and improve the screening accuracy. The design of the present application simplifies the transmission structure through the direct connection of the first connecting rod 120 and the first driving mechanism 5, which improves the stability and reliability of the vibration. In addition, the reciprocating design of the first connecting rod 120 makes the vibration of the screen more uniform, which can effectively avoid the accumulation or blockage of tobacco on the screen, ensuring the continuity and efficiency of the screening process.
[0057] As a preferred example of the present embodiment, the first limiting insertion shaft 22 is provided with a limiting protrusion 110 on both sides of the first limiting insertion hole 111, and the limiting protrusion 110 can abut against the first frame body 1 to limit the displacement of the first limiting insertion shaft 22.
[0058] The design of the limiting protrusions 110 further enhances the stability of the first screen 2, preventing it from shifting or loosening during vibration, ensuring the continuity and reliability of the screening process. In traditional screening equipment, the screen is prone to shift due to component loosening or wear during vibration, affecting the screening effect. The design of the present application sets limiting protrusions 110 on the limiting shaft, so that the screen can always remain stable during vibration, avoiding shifting or loosening caused by vibration. This design is particularly suitable for high-strength, long-running environments in tobacco processing workshops, significantly improving the service life and production efficiency of the equipment.
[0059] Specifically, the distance between the two limiting protrusions 110 is L1, and the length of the first limiting insertion hole 111 is L2, 1.2L1≤L2≤1.5L1. In this way, enough pulling clearance is left for the first limiting shaft 22.
[0060] Preferably, the first limiting shaft 22 is provided with a limiting slot, and the limiting protrusions 110 are detachably connected with the first limiting shaft 22 through the plug-in cooperation with the limiting slot, which facilitates the assembly of the first limiting shaft 22 and avoids interference of the limiting protrusions 110 during the assembly of the first limiting shaft 22 and the first limiting slot.
[0061] As a preferred embodiment of the present application, the rack 1 further comprises a second rack body 12 provided with a second limiting insertion hole 121 and a third rack body 13 provided with a third limiting insertion hole 131, the second screen 3 is provided with a second limiting shaft 32, and the third screen 4 is provided with a third limiting shaft 42, the second screen 3 is installed on the second rack body 12 through the plug-in cooperation of the second limiting shaft 32 and the second limiting insertion hole 121, and the third screen 4 is installed on the third rack body 13 through the plug-in cooperation of the third limiting shaft 42 and the third limiting insertion hole 131.
[0062] The present embodiment does not limit the connection mode of the first screen 2, the second screen 3, and the third screen 4 with the rack 1, which can adopt any of the following embodiments:
[0063] In the first embodiment, the first frame body 1 is rotatably connected to the rack 1. The stem-separation machine further comprises a first locking member movably mounted on the rack 1. The first locking member has a first locking position abutting against the first frame body 1 and a first separation position separating from the first frame body 1. When the first locking member is in the first locking position, the first frame body 1 is restricted from rotating relative to the rack 1. When the first locking member is in the first separation position, the first frame body 1 can rotate relative to the rack 1 to tilt the first screen 2. The rotation of the first frame body 1 and the cooperation of the first locking member allow the first screen 2 to adjust the tilt angle as needed, facilitating the cleaning of residual stems on the first screen 2 or the replacement of the screen. Through the rotation of the first frame body 1 and the cooperation of the first locking member, the operator can quickly adjust the tilt angle of the first screen 2, facilitating the cleaning of residual stems or the replacement of the first screen 2 without the need to disassemble the equipment or stop the operation. This design significantly improves the maintenance efficiency and operational convenience of the equipment, especially suitable for high-intensity and long-time running environments in tobacco processing workshops. In addition, the design of the first locking member also enhances the stability of the equipment, preventing accidental tilting of the first screen 2 during vibration, ensuring the continuity and reliability of the screening process.
[0064] In the second embodiment, the second frame body 12 is rotatably connected to the rack 1. The stem-separation machine further comprises a second locking member movably mounted on the rack 1. The second locking member has a second locking position abutting against the second frame body 12 and a second separation position separating from the second frame body 12. When the second locking member is in the second locking position, the second frame body 12 is restricted from rotating relative to the rack 1. When the second locking member is in the second separation position, the second frame body 12 can rotate relative to the rack 1 to tilt the second screen 3.
[0065] In the third embodiment, the third frame body 13 is rotatably connected to the rack 1. The stem-separation machine further comprises a third locking member movably mounted on the rack 1. The third locking member has a third locking position abutting against the third frame body 13 and a third separation position separating from the third frame body 13. When the third locking member is in the third locking position, the third frame body 13 is restricted from rotating relative to the rack 1. When the third locking member is in the third separation position, the third frame body 13 can rotate relative to the rack 1 to tilt the third screen 4.
[0066] As a preferred embodiment of the present application, the first screen 2, the second screen 3, and the third screen 4 are respectively rotationally connected with the rack 1, and the stem separator further comprises a material collecting module, which comprises a material collecting bin 8 adjacent to the rack 1, the material collecting bin 8 comprising a first material collecting groove, a second material collecting groove, and a third material collecting groove, and further comprising a first material collecting disc 9, a second material collecting disc, and a third material collecting disc, the first material collecting disc 9 having a first material collecting position located below the first screen 2 and a first avoiding position located in the first material collecting groove, the second material collecting disc having a second material collecting position located below the second screen 3 and a second avoiding position located in the second material collecting groove, and the third material collecting disc having a third material collecting position located below the third screen 4 and a third avoiding position located in the third material collecting groove.
[0067] The design of the material collecting module enables the classified collection of the screened stems, avoiding the mixing of the stems. The movable design of the first material collecting disc 9, the second material collecting disc, and the third material collecting disc makes the material collecting process more flexible and facilitates the transfer and processing of the stems. In a tobacco processing workshop, the screened stems need to be classified and collected and then transferred to the next process. Traditional equipment usually requires manual intervention, which is complicated and easy to cause the stems to be spilled or mixed. The design of the present application integrates the material collecting module, enabling the automatic classified collection of the screened stems and the transfer of the stems to the designated position through the movable material collecting disc without manual intervention. This design significantly improves the efficiency and accuracy of stem management and is particularly suitable for large-scale and continuous production scenarios in a tobacco processing workshop. In addition, the compact design of the material collecting module also reduces the floor space occupied by the equipment, reducing the space occupation in the workshop and providing higher economic benefits and operational convenience for tobacco processing enterprises.
[0068] Specifically, in the present embodiment, the rack 1 is provided with a limiting piece, which can limit the rotation of the first screen 2, the second screen 3, and the third screen 4 respectively, while not limiting their reciprocating vibration in the horizontal direction.
