Technical Field
[0001] This invention relates to the field of cigarette manufacturing technology, specifically to a cigarette empty tube smoke generator and a cigarette manufacturing method. Background Technology
[0002] In the cigarette production process, while ensuring the safety of tobacco products, it is necessary to consider the satisfaction and comfort of smokers. Studies have shown that the intrinsic qualities of cigarettes, such as the composition ratio of tobacco products, the density of tobacco filling, and the uniformity of filling, all affect the aroma quality and the release of harmful components in the smoke.
[0003] Laboratory researchers are attempting to improve the intrinsic quality of cigarettes by altering the ingredient ratios of tobacco products. When developing new formulated tobacco products, it's necessary to prepare cigarettes from pre-mixed formulated tobacco and conduct aroma tests. However, due to the limited quantity of experimental samples, it's impossible to manufacture formulated cigarettes on a production line. Currently, the primary method used in laboratories to produce formulated cigarettes from formulated tobacco is by manually filling empty cigarette tubes. This process is entirely manual, resulting in uncontrollable filling density and extremely low efficiency.
[0004] To facilitate the production of formulated cigarettes, some researchers have implemented semi-automated tobacco filling using mechanical mechanisms. Examples include patent applications CN202321318956.7 ("An Automatic Filling Mechanism for a Tobacco Filling Machine") and CN202410267298.6 ("An Automatic Filling Equipment for Multi-Specification Tobacco Shreds"). These devices address the need for automated cigarette production to varying degrees and can achieve quantitative weighing. However, the state of the tobacco shreds during feeding, transfer, compaction, and filling is dynamic. Tobacco shreds are not morphologically stable materials and are prone to uneven density distribution in the final compacted rods due to uneven morphology. Furthermore, since this solution is used in the experimental stage before cigarette production, the quality requirements for cigarette preparation are higher. Therefore, the degree of automation optimization for the entire process of tobacco shreds from feeding, weighing, transfer, compaction, and filling still needs to be improved to enhance the quality of each step and ultimately ensure the quality of the final product.
[0005] In summary, it is urgent to address the challenges of achieving uniform tobacco spreading, the uncontrollable density and uniformity of tobacco shavings, which affect the aroma quality of blended tobacco and the release of harmful substances in the smoke, as well as to optimize the specific processing steps of each stage to improve the quality of the finished product.
[0006] In order to solve the above problems, people have been seeking an ideal technological solution. Summary of the Invention

[0037] Based on the above, the weighing transfer module includes a weighing component, a weighing tray, a rotating bracket, a lifting drive component, and a translation drive component;
[0038] The top of the weighing component is a weighing platform, and the weighing tray is gantry-shaped and is movably placed on the weighing platform.

[0041] At least two positioning pins are provided, and the two positioning pins are set on the rear support arm of the bracket. When the bracket rotates to unload, the rear support arm rotates higher than the front support arm. The bottom end of the positioning pin is the end head, the middle part is the column, and the top end is the screw.

A high-pressure air circuit interface connecting the arc groove is provided at the rear end of the arc groove.
[0045] A method for preparing cigarettes, comprising the following steps:
[0046] A certain amount of prepared tobacco shreds is placed into the inlet of the tobacco shreds feeding module, a certain amount of empty cigarette tubes are placed into the hopper of the empty cigarette tube feeding module, and then the device is started.
[0047] The tobacco shreds are conveyed in a coordinated manner through the feeding channel, tobacco loosening roller and guide plate to complete the loosening of the tobacco shreds. After entering the vibrating trough, they are sent into the weighing tray along with the vibrating trough and the rotating return baffle mechanism to complete the first vibration of the tobacco shreds.
[0048] After the tobacco shreds are briefly weighed on the weighing component and reach the specified weight, they are lifted, translated, and flipped at a specific angle by the lifting drive component, translation drive component, and rotating bracket in the weighing transfer module, and the metered amount of tobacco shreds are poured into the tobacco shred guide trough.
[0049] The tobacco entering the tobacco guide groove is shaken twice by the shaking drive component. At the same time, the movable semi-circular arc groove pusher and the tobacco pressing plate cooperate to keep the tobacco in a closed space for compressing into rods and gradually compressing it into rods.
[0050] The empty cigarette tubes are fed from the hopper into the arc groove by the cooperation of the empty tube lifting mechanism and the empty tube transfer mechanism, and are then pushed by the empty tube transfer mechanism to the receiving interface on the other side of the tobacco guide groove.
[0051] During the docking of empty cigarette tubes, the shaking drive assembly drives the tobacco guide groove to move horizontally, aligning the pointed tip of the receiving interface with the axis of the empty cigarette tube. Then, the empty tube transfer mechanism is controlled to move forward a short distance, allowing the pointed tip of the receiving interface to enter the empty cigarette tube. Then, the shaking drive assembly drives the tobacco guide groove to move horizontally, aligning the axis of the receiving interface with the axis of the empty cigarette tube. After the empty tube transfer mechanism moves forward to the bottom, it is controlled to return to its original position.
[0052] When the control module is working, the push rod pushes the compacted tobacco out of the tobacco guide groove. At the same time, the empty cigarette tube is pushed out simultaneously, and the tobacco fully enters the empty cigarette tube to form a cigarette, which then falls naturally after moving away from the tobacco guide groove.
[0053] This invention has outstanding substantive features and significant progress compared to the prior art. Specifically, this invention has the following advantages:
[0054] 1. During the feeding process, the tobacco shreds are loosened and vibrated to achieve uniformity in the first stage. During the compaction process, the tobacco shreds are shaken a second time by the shaking drive component to ensure that the tobacco shreds are fully and evenly distributed in the tobacco guide groove. Ultimately, the distribution of the tobacco shreds is uniform and stable, and the density distribution after compaction is uniform, resulting in higher quality cigarettes and better experimental results.
[0055] 2. In the weighing process, the weighing tray is placed on top of the weighing component, and the two can be separated, which is consistent with the normal weighing process and ensures the accuracy of weighing. The operation of the weighing transfer module does not interfere with the weighing process, which can maximize the accuracy of weighing.
[0056] 3. In the compaction process, the height space is limited at the top and bottom, and the tobacco is compacted horizontally by a combination of movable and fixed semi-circular grooves to prevent tobacco from overflowing and to ensure more stable quality of the tobacco sticks.
[0057] 4. In the cigarette empty tube feeding process, only one cigarette empty tube is fed at a time, and it is connected to the receiving interface of the tobacco guide groove through dynamic centering to ensure the connection accuracy to the maximum extent, avoid damage to the paper wall of the cigarette empty tube, and ultimately ensure that the quality of cigarette production remains at a high level.

[0081] The technical solution of the present invention will be further described in detail below through specific embodiments.
[0082] like Figures 1-15 As shown, a cigarette empty tube smoke generator includes a support 7, a tobacco feeding module 1, a weighing and transferring module 2, a shaking and compacting module 3, an ejection module 4, an empty tube feeding module 5, and a main control module 6.
[0083] Each functional module will be explained and described one by one.
[0084] The tobacco feeding module 1 is installed in the upper part of the bracket 7 and is used to loosen, vibrate, and transport the tobacco to the weighing and transfer module 2.
[0085] Specifically, in this embodiment, as Figure 3 and Figure 4As shown, the tobacco feeding module 1 includes a feeding channel 11, a guide plate 12, a tobacco loosening roller 13, a vibration groove 14, a rotating return baffle mechanism 15, and a weighing component 21;
[0086] The material feeding channel 11 is located above the vibration groove 14. The tobacco loosening roller 13 is installed in the middle of the material feeding channel 11. The guide plate 12 is located inside the material feeding channel 11 and above the tobacco loosening roller 13. The guide plate 12 includes a left guide plate 121 and a right guide plate 122. The upper ends of the left guide plate 121 and the right guide plate 122 are respectively fixed to the two side walls of the material feeding channel 11, and the lower ends converge towards the middle to the tobacco loosening roller 13. The bottom end of the left guide plate 121 and / or the right guide plate 122 is provided with a comb-like structure. The tobacco loosening roller 13 is provided with conical loosening teeth that are adapted to the comb-like structure. The guide plate 12 is used to guide the tobacco to the working area of the tobacco loosening roller 13.
[0087] In detail, the tobacco shreds of the batch are taken and fed into the feeding channel 11. Under the combined action of the tobacco loosening roller 13 and the guide plate 12, the tobacco shreds are loosened and transferred to the vibration trough 14 below the feeding channel 11. The vibration power of the vibration trough 14 serves as the driving force, causing the tobacco shreds to move forward to the discharge port along the inclined area at the front and lower. The rotating return baffle mechanism 15 is used to control the amount of tobacco shreds passing through, thereby achieving the purpose of quantitative conveying.
[0088] The tobacco loosening roller 13 is driven to rotate by an independent motor through a hollow rotating platform. Of course, the rotation can also be achieved by direct motor drive.
[0089] The front half of the vibration groove 14 is inclined forward and downward, and the lower end outlet of the material discharge channel 11 is located in the rear area of the front lower part of the vibration groove 14. The vibration groove 14 is driven by a straight vibrator, and the tobacco shreds are gradually transferred to the front outlet along the inclined vibration groove through vibration.
[0090] The rotating return material baffle mechanism 15 is installed in the central area of the front half of the vibration trough 14. The rotating return material baffle mechanism 15 includes a stepper motor 151, a mounting bracket 152, a rotating shaft 153, and at least one baffle 154. The stepper motor 151 is fixed by the mounting bracket 152. The output shaft of the stepper motor 151 is coaxially fixed with the rotating shaft 153. The side wall of the vibration trough 14 is provided with a through hole for the rotating shaft 153 to work. The baffle 154 is fixed on the rotating shaft 153 and rotates with the rotating shaft. The lowest point of the rotation of the baffle 154 is close to the bottom of the vibration trough 14, and both ends of the baffle 154 are close to the wall of the vibration trough 14. It pushes the material forward by flipping.
[0091] In this embodiment, the number of baffles 154 is controlled to be 2, distributed at 180°. By controlling the working state of the stepper motor 151, the rotation frequency of the baffles 154 can be controlled, thereby controlling the amount of tobacco passing through each time. The comb structure can be used to separate the tobacco, prevent the tobacco from tangling together, and improve the subsequent weighing accuracy.
[0092] The weighing component 21 is located below the front outlet of the vibration groove 14. In actual operation, the weighing component 21 is associated with the tobacco loosening roller 13 and the rotating return baffle mechanism 15 through the main control module 6. The amount and speed of the conveyed tobacco are adjusted in real time according to the weighing data, so that the weighing component 21 can accurately meet the standard for the amount of tobacco weighed.
[0093] The weighing and transfer module 2 is installed in the central area of the bracket 7 and is used to weigh the tobacco and transfer it to the shaking and compaction module 3.
[0094] In this embodiment, as Figure 5 and Figure 6 As shown, the weighing transfer module 2 includes a weighing component 21, a weighing tray 22, a rotating bracket 23, a lifting drive component 24, and a translation drive component 25.
[0095] The top of the weighing component 21 is a weighing platform, and the weighing tray 22 is gantry-shaped. In this embodiment, a bucket-shaped wire-holding groove 221 extending downward is provided in the central area of the weighing tray 22, so that the cross-section of the weighing tray 22 is similar to "M". The weighing tray 22 is movably placed on the weighing platform.
[0096] The rotating bracket 23 includes a bracket 231, a positioning pin 232, and a rotating drive mechanism 233. The bracket 231 is inserted into the lower inner side of the weighing tray 22 to support the weighing tray 22. The positioning pin 232 is fixed to one side of the bracket 231. The weighing tray 22 is provided with a pin hole 234 corresponding to the positioning pin 232. The middle section of the positioning pin 232 passes through the pin hole 234 and its diameter is smaller than the diameter of the pin hole 234. The two ends of the positioning pin 232 are provided with stop structures to prevent it from coming off the pin hole. The bracket 231 is correspondingly U-shaped to form two support arms. The two support arms of the bracket support the lower sides of the bucket-shaped wire-holding groove of the weighing tray. In this embodiment, the rotating drive mechanism 33 is a swing cylinder. In other embodiments, a rotating drive motor can also be used.
[0097] In this embodiment, at least two positioning pins 232 are provided, and the two positioning pins 232 are provided on the rear support arm of the bracket 231. When the bracket 231 rotates to unload, the rear support arm rotates higher than the front support arm. The bottom end of the positioning pin 232 is a head, the middle part is a column, and the top end is a screw. The top screw is connected to the column through a washer to form a structure with the smallest diameter at the column and the larger diameter at both ends. The head is welded and fixed to the bracket.
[0098] In a preferred embodiment, to prevent the bottom end of the positioning pin 232 from being too large and too high after being lifted, which would cause the weighing tray 22 to tilt too much when it is lifted in a non-rotating state, a pad 235 to compensate for the height difference can be provided on the other side of the support arm, so that the weighing tray 22 has no tilt angle when it is lifted in a non-rotating state, or the tilt angle is controlled within a small range to prevent tobacco from leaking out.
[0099] The lifting drive assembly 24 is disposed on one side of the weighing assembly 21, and the rotary drive mechanism 233 is installed on the moving end of the lifting drive assembly 24. In this embodiment, the lifting drive assembly 24 includes a vertically arranged slide cylinder, and the rotary drive mechanism 233 is installed on the moving end of the slide cylinder through a right-angle bracket.
[0100] In other embodiments, the lifting drive assembly 24 may also employ common linear motion mechanisms such as linear motors and lead screw mechanisms.
[0101] The translation drive assembly 25 is disposed below the lifting drive assembly 24, and the main body of the lifting drive assembly 24 is mounted on the moving end of the translation drive assembly 25. In this embodiment, the translation drive assembly 25 includes a horizontally sliding linear slide device; in other embodiments, conventional linear motion mechanisms such as electric lead screws may also be used.
[0102] The translation drive assembly 25, the lifting drive assembly 24, and the rotating bracket 23 are perpendicular to each other in different planes. The translation drive assembly 25 is used for material position transfer, the lifting drive assembly is used to lift the weighing tray 22 and lift the weighing platform, and the rotating bracket 3 is used to rotate the weighing tray 22 to pour out the tobacco.
[0103] At the end of the stroke of the translation drive component 25, a feeding guide hopper 26 is provided at the height of the rotating bracket 23. The feeding guide hopper 26 is a vertical channel with a wide opening at the top and a gradually narrowing opening at the bottom, used to guide the received tobacco into the tobacco guide groove below.
[0104] In the weighing state, the lifting drive component 24 is controlled to lower the rotating bracket 23 to a certain height. The overall thickness of the rotating bracket 23 is less than the height of the weighing tray 22. At this time, the weighing tray 22 does not contact the rotating bracket 23 and the positioning pin 232. The overall weight of the weighing tray 22 can act on the upper end of the weighing component 21, thereby achieving high-precision weighing.
[0105] After weighing is completed, the lifting drive component 24 is raised to increase the height. As the bracket 231 is raised, the entire weighing tray 22 is lifted horizontally and separated from the weighing component 21.
[0106] Then, control the translation drive component 25 to translate to the feeding guide hopper 26. After translating into place, drive the rotary drive mechanism 233 to rotate at a set angle, generally close to 90°, to pour the tobacco into the feeding guide hopper 26. Drive the rotary drive mechanism 233 to rotate back to the horizontal state. Control the translation drive component 25 and the lifting drive component 24 in sequence to finally return the weighing tray 22 to its original position.
[0107] During the process of flipping and tilting the tobacco, the positioning pin 232 prevents the weighing tray 22 from separating from the rotating bracket 23. The upper diameter of the positioning pin 232 is larger than the diameter of the pin hole, so that the weighing tray 22 will not fall off naturally. During the process of rotating to return to the horizontal position, due to the design of the M-shaped structure, the lower support part of the weighing tray 22 and the U-shaped bracket 231 can adaptively return to their original positions.
[0108] like Figures 7-12 As shown, the shaking and compaction module 3 is installed in the bottom area of the bracket 7, including a tobacco shred guide channel 31, a shaking drive component 32, and a tobacco shred compaction component 33. The tobacco shred guide channel 31 is used to receive tobacco shreds from the weighing and transfer module. That is, in the initial state, the opening of the tobacco shred guide channel 31 is located directly below the feed hopper 26.

The shaking motor 321 drives the movable base plate 35 to perform periodic reciprocating linear motion along the slide rail 36 through the drive disk 322, the rocker arm 323, and the connecting seat 324. The other end of the shaking motor 321 is equipped with a disc-shaped photoelectric switch cam 326 that rotates coaxially with the output shaft. A corresponding groove-shaped photoelectric switch trigger 325 is provided on the base 34. The outer edge of the disc-shaped photoelectric switch cam 326 is provided with a notch for triggering the photoelectric switch trigger 325, which is used to record the shaking frequency of the shaking motor 321.
[0112] The bottom front side of the tobacco shred guide channel 31 is provided with a fixed semi-circular arc groove 315 with the groove opening facing horizontally backward and the lower edge of the groove aligned with the bottom of the tobacco shred guide channel. Specifically, the tobacco shred guide channel 31 includes a lower pressing plate 311, an upper pressing plate 312, a guide guard plate 313, and an upper enclosing upright plate 314.

The guide guard plate 313 is provided with positioning protrusions for the notch to achieve high-precision locking and fixing of the three. The inner side of the guide guard plate 313 is provided with the fixing semi-circular arc groove 315. The width of the guide guard plate 313 is smaller than the width of the upper pressure plate 312 so that a guide groove 316 is formed at the junction of the upper pressure plate 312, the lower pressure plate 311 and the guide guard plate 313.
[0113] The tobacco compaction assembly 33 includes a movable semi-circular groove pusher plate 331 and a tobacco pressing plate 332.
[0114] The movable semi-circular arc groove push plate 331 includes a first linear slide 3311, a push plate 3312, and a slider 3313. The first linear slide 3311 is mounted on a movable base plate 35. The push plate 3312 is L-shaped and fixed to the moving end of the first linear slide 3311. The front end of the push plate 3312 is connected to the slider 3313. The slider 3313 slides in cooperation with the bottom of the tobacco guide groove 31. The width of the slider 3313 is the same as the width of the tobacco guide groove 31. The front end of the slider 3313 is provided with the semi-circular arc groove structure.
[0115] The tobacco pressing plate 332 is a pressing plate that can be raised and lowered and can move in the front and back direction. The bottom surface of the pressing plate is a plane, and the outer contour of the pressing plate matches the inner contour of the guide groove.
[0116] Specifically, the tobacco pressing plate 332 includes a second linear slide 3321, a third linear slide 3322, and a pressing plate 3323. The second linear slide 3321 is vertically mounted on the movable base plate 35. The third linear slide 3322 is mounted on the moving end of the second linear slide 3321 and is set horizontally. The pressing plate 3323 is mounted on the moving end of the third linear slide 3322. The moving direction of the third linear slide 3322 is the same as the moving direction of the first linear slide 3311. The width of the pressing plate 3323 is consistent with the inner width of the upper pressing plate 312 and the upper enclosing upright plate 314. The front end face of the pressing plate 3323 is a pushing vertical plane, and the bottom surface of the pressing plate 3323 is a plane.
[0117] The movable semi-circular arc groove pusher plate 331 slides in conjunction with the bottom of the tobacco shred guide groove 31. The front end of the movable semi-circular arc groove pusher plate 331 is provided with a semi-circular arc groove structure that can form a circle with the fixed semi-circular arc groove 317. The top surface of the movable semi-circular arc groove pusher plate 331 is a plane. The guiding direction of the slide rail 36 is the same as or perpendicular to the moving direction of the movable semi-circular arc groove pusher plate 331.
[0118] The thickness of the guide groove 316 is the same as the thickness of the slider 3313; the upper enclosing plate 314 is U-shaped and fixed to the upper end of the upper pressure plate 312, and the inner boundary of the upper enclosing plate 314 is aligned with the inner boundary of the upper pressure plate 312.
[0119] The pressure plate 3323, the fixed semi-circular groove 315, the movable semi-circular groove push plate 331, and the bottom of the tobacco shred guide groove 31 together form the space for compressing tobacco shreds into rods.
[0120] Brief description of the work process:
[0121] After a certain amount of tobacco is received in the tobacco guide groove 31, in the initial state, a certain gap is left between the movable semi-circular arc groove pusher plate 331 and the fixed semi-circular arc groove 315, and the lower end face of the pressure plate 3323 is aligned with the upper end face of the slider 3313. The tobacco that is fed in falls into the space left between the movable semi-circular arc groove pusher plate 331 and the fixed semi-circular arc groove 315.
[0122] First, start the shaking motor 321 to shake the entire movable base plate 35 evenly, so that the tobacco in the tobacco guide channel 31 shakes evenly, loosens some temporarily piled tobacco, and stops the shaking once the tobacco is evenly distributed in the entire tobacco guide channel 31.
[0123] Then, the pressure plate 3323 is raised to a certain height and moved forward so that it can cover the space between the movable semi-circular groove push plate 331 and the fixed semi-circular groove 315. Then, the pressure plate 3323 is moved down to the point of contacting the upper surface of the slider 3313, pressing the fluffy tobacco into the enclosed space.
[0124] Next, the movable semi-circular groove pusher plate 331 is moved forward until it forms a circle with the fixed semi-circular groove 315, which can then compress the fluffy tobacco into a rod.
[0125] The ejection module 4 is installed on the bracket 1 on one side of the tobacco guide groove 31 and is used to eject the compacted tobacco horizontally from the tobacco guide groove.
[0126] In this embodiment, the ejection module 4 includes a linear motor assembly 41, a linear slider 42, and a push rod 43 mounted on a movable base plate. The guide guard plate 313 of the tobacco guide channel 31 has through holes on both sides that are coaxial with the fixed semi-circular arc groove. The push rod 43 is coaxial with the through holes. A receiving interface 317 is provided on one side of the guide guard plate 313 corresponding to the outlet of the through hole. The opening of the receiving interface 317 is set into a pointed shape.
[0127] like Figures 13-15 As shown, the empty tube feeding module 5 is installed on the bracket 1 on the other side of the tobacco guide groove 31, and is used to receive the compacted tobacco into the empty tube to make cigarettes;
[0128] In this embodiment, the empty cylinder feeding module 5 includes a hopper 51, an empty cylinder lifting mechanism 52, and an empty cylinder transfer mechanism 53;
[0129] The hopper 51 includes an inclined bottom wall 511 and two side walls 512 on both sides. The front end of the hopper is empty. The width of the bottom wall 511 of the hopper is greater than the length of the empty cigarette tube 8.
[0130] The empty tube lifting mechanism 52 includes an empty tube feeding top plate 521 that can be raised and lowered and stopped at the front end of the hopper, and a lifting drive mechanism 522 for driving the empty tube feeding top plate to move up and down. The top of the empty tube feeding top plate is provided with a guide surface 523 that is inclined forward and downward. The width of the guide surface 523 is equal to or slightly larger than the diameter of the cigarette empty tube 8 so that only one cigarette empty tube can be lifted at a time.
[0131] The empty cylinder transfer mechanism 53 includes an empty cylinder translation placement plate 531 that is closely attached to the outer side of the empty cylinder feeding top plate and a translation drive mechanism 532 that drives the empty cylinder translation placement plate to move horizontally. The top of the empty cylinder translation placement plate is provided with an arc groove 533 for accommodating cigarette empty cylinders. The rear end of the arc groove 533 is provided with a stop surface 534 and the front end is empty.
[0132] When the empty cylinder feeding top plate 521 is in the high position of its stroke, the extension line of the guide surface can extend to the top of the arc groove 533.
[0133] The axis of the arc groove 533 is dynamically adapted to the axis of the bearing interface 317 in the tobacco guide groove 31.
[0134] Specifically, a certain amount of empty cigarette tubes 8 are manually placed into the hopper 51. The empty cigarette tubes 8 can be stacked in multiple layers, or only one layer can be stacked to ensure accuracy. The following description, with reference to the attached diagram, illustrates the case of stacking one layer of empty cigarette tubes 8.
[0135] First, the empty cigarette tube lifting mechanism 52 is lowered so that the guide surface 523 at the top of the empty cigarette tube feeding plate 521 is lowered to be aligned with the bottom wall 511. The frontmost empty cigarette tube 8 moves forward a distance under its own weight and the pressure of the empty cigarette tube 8 behind it. The overall width of the empty cigarette tube feeding plate 521 is equal to or slightly larger than the diameter of a single empty cigarette tube 8, so that when the empty cigarette tube feeding plate 521 moves upward, only one empty cigarette tube can be lifted by the guide surface 523. At the same time, the rear side of the front empty cigarette tube translation placement plate 531 serves as a stop surface to prevent the empty cigarette tube 8 from moving further.
[0136] When the empty cylinder feeding top plate 521 moves to the highest position, the lowest position on the front side of the guide surface 523 exceeds the height of the arc groove 533 of the empty cylinder translation placement plate 531, and the cigarette empty cylinder 8 loses the stop constraint and enters the arc groove 533 of the empty cylinder translation placement plate 531 under its own gravity.
[0137] Driven by the translation drive mechanism 532, the empty cigarette tube transfer mechanism 53 transfers the empty cigarette tube 8 to the receiving interface.
[0138] The transfer direction can be along the axial direction of the empty cigarette tube or in other directions; in this embodiment, it is along the axial direction.
[0139] In another embodiment, the empty cigarette tubes do not need to be prepared in advance and can be prepared on an ad hoc basis.
[0140] Specifically, such as Figure 16As shown, it also includes a cigarette blowing empty tube module 9, which includes a lifting slide 91, a flexible air passage plate 92, and a guide tube 93. The lifting slide 91 is located near the empty tube transfer mechanism 53. The flexible air passage plate 92 is installed on the moving end of the lifting slide 91. The flexible air passage plate 92 itself is a solid plate, and the material can be rubber. One end of the flexible air passage plate 92 has a pressure head 94 with a corresponding arc groove at its lower part. The pressure head 94 is designed as a flexible structure, and its function is to lift and lower the cigarette. The cigarette filter tip in the arc groove 533 is pressed tightly, and the cigarette filter tip is sealed relative to the arc groove 533. The guide tube 93 is installed at the lower part of the other end of the flexible air circuit plate 92. The distance between the guide tube 93 and the pressure head 94 is adapted according to the length of the cigarette and the length of the arc groove, for example, slightly larger than the length of the cigarette, so that the tobacco blown out of the cigarette can enter the guide tube 93. The inlet end of the guide tube 93 is horizontal and the outlet end is vertically downward. A high-pressure air circuit interface 95 connecting the arc groove is provided at the rear end of the arc groove.
[0141] In use, the object placed in the original empty tube feeding module 5 is a cigarette 10 with tobacco. After the cigarette is fed into the arc groove 533 by the empty tube feeding module 5, the cigarette blowing empty tube module 9 starts to work. First, the lifting slide 91 descends, and the flexible structure of the pressure head 94 seals the rear space of the arc groove 533 together with the cigarette filter. At the same time, the front guide tube 93 is directly facing the front of the cigarette, and the high-pressure gas connected to the high-pressure gas circuit interface 95 blows out the tobacco in the cigarette. The blown tobacco is discharged from the front guide tube 93, and the cigarette empty tube is prepared. Then the cigarette blowing empty tube module 9 is removed, and the subsequent cigarette empty tube docking process continues.
[0142] The main control module 6 is connected to the tobacco feeding module 1, the weighing and transfer module 2, the shaking and compaction module 3, the ejection module 4, and the empty cylinder feeding module 5 to control the working status of each module.
[0143] The cigarette manufacturing method is carried out through the following steps:
[0144] A certain amount of prepared tobacco shreds is placed into the inlet of the tobacco shreds feeding module, a certain amount of empty cigarette tubes are placed into the hopper of the empty cigarette tube feeding module, and then the device is started.
[0145] The tobacco shreds are conveyed in a coordinated manner through the feeding channel, tobacco loosening roller and guide plate to complete the loosening of the tobacco shreds. After entering the vibrating trough, they are sent into the weighing tray along with the vibrating trough and the rotating return baffle mechanism to complete the first vibration of the tobacco shreds.
[0146] After the tobacco shreds are briefly weighed on the weighing component and reach the specified weight, they are lifted, translated, and flipped at a specific angle by the lifting drive component, translation drive component, and rotating bracket in the weighing transfer module, and the metered amount of tobacco shreds are poured into the tobacco shred guide trough.
[0147] The tobacco entering the tobacco guide groove is shaken twice by the shaking drive component. At the same time, the movable semi-circular arc groove pusher and the tobacco pressing plate cooperate to keep the tobacco in a closed space for compressing into rods and gradually compressing it into rods.
[0148] The empty cigarette tubes are fed from the hopper into the arc groove by the cooperation of the empty tube lifting mechanism and the empty tube transfer mechanism, and are then pushed by the empty tube transfer mechanism to the receiving interface on the other side of the tobacco guide groove.
[0149] During the docking of empty cigarette tubes, the shaking drive assembly drives the tobacco guide groove to move horizontally, aligning the pointed tip of the receiving interface with the axis of the empty cigarette tube. Then, the empty tube transfer mechanism is controlled to move forward a short distance, allowing the pointed tip of the receiving interface to enter the empty cigarette tube. Then, the shaking drive assembly drives the tobacco guide groove to move horizontally, aligning the axis of the receiving interface with the axis of the empty cigarette tube. After the empty tube transfer mechanism moves forward to the bottom, it is controlled to return to its original position.
[0150] The advantage of doing this is that it first aligns the pointed tip with the center of the empty cigarette tube 8, avoiding the problem of not being able to fit it directly due to the curled edge of the empty cigarette tube 8. This ensures that there is no damage during the docking process. After entering a certain distance, the receiving interface is controlled to return to its original position, so that the two axes are coaxial. The empty cigarette tube 8 is accurately fitted outside the receiving interface and moves to the bottom, so as to facilitate the next step of filling the tobacco.
[0151] When the control module is working, the push rod pushes the compacted tobacco out of the tobacco guide groove. At the same time, the empty cigarette tube is pushed out simultaneously, and the tobacco fully enters the empty cigarette tube to form a cigarette, which then falls naturally after moving away from the tobacco guide groove.
[0152] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of the present invention or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of the present invention, and all such modifications and substitutions should be covered within the scope of the technical solutions claimed in the present invention.

The two ends of the positioning pin are provided with stop structures to prevent it from coming off the pin hole. The weighing tray has a downward-extending bucket-shaped wire-holding groove in its central area, making the cross-section of the weighing tray resemble an "M" shape. The bracket is correspondingly U-shaped to form two support arms, which are supported on both sides below the bucket-shaped wire-holding groove of the weighing tray. At least two positioning pins are provided, and the two positioning pins are set on the rear support arm of the bracket. When the bracket rotates to unload, the rear support arm rotates higher than the front support arm. The bottom end of the positioning pin is the end head, the middle part is the column, and the top end is the screw. The top screw is connected to the column through a washer to form a structure with the smallest diameter at the column and the larger diameter at both ends. The end head is welded and fixed to the bracket. The lifting drive assembly is located on one side of the weighing assembly, and the rotary drive mechanism is installed on the moving end of the lifting drive assembly. The translation drive component is located below the lifting drive component, and the main body of the lifting drive component is mounted on the moving end of the translation drive component.
9. The cigarette empty tube smoke generator according to claim 8, characterized in that: It also includes a cigarette blowing empty tube module, which includes a lifting slide, a flexible air circuit plate, and a guide tube. The lifting slide is located near the empty tube transfer mechanism. The flexible air circuit plate is installed on the moving end of the lifting slide. A pressure head corresponding to the arc groove is provided at the lower part of one end of the flexible air circuit plate. The guide tube is installed at the lower part of the other end of the flexible air circuit plate. The inlet end of the guide tube is horizontal and the outlet end is vertically downward. A high-pressure air circuit interface connecting the arc groove is provided at the rear end of the arc groove.
10. A method for preparing cigarettes, characterized in that: Based on the cigarette empty tube extinguisher according to any one of claims 1-9, the following steps are performed: A certain amount of prepared tobacco shreds is placed into the inlet of the tobacco shreds feeding module, a certain amount of empty cigarette tubes are placed into the hopper of the empty cigarette tube feeding module, and then the device is started. The tobacco shreds are conveyed in coordination by the feeding channel, loosening roller and guide plate of the tobacco feeding module to loosen the tobacco shreds. After entering the vibration trough of the tobacco feeding module, they are sent to the weighing tray of the weighing transfer module along with the vibration trough and the rotating return baffle mechanism of the tobacco feeding module to complete one vibration and uniformization of the tobacco shreds. After the tobacco shreds are briefly weighed and reach the target weight in the weighing and transfer module, they are lifted, translated, and flipped at a specific angle by the lifting drive component, translation drive component, and rotating bracket in the weighing and transfer module, and the metered amount of tobacco shreds are poured into the tobacco shred guide trough. The tobacco entering the tobacco guide groove is shaken twice by the shaking drive component. At the same time, the movable semi-circular arc groove pusher and the tobacco pressing plate cooperate to keep the tobacco in a closed space for compressing into rods and gradually compressing it into rods. The empty cigarette tubes are fed from the hopper of the empty cigarette feeding module into the arc groove of the empty cigarette feeding module by the cooperation of the empty tube lifting mechanism and the empty tube transfer mechanism, and are then pushed by the empty tube transfer mechanism to the receiving interface on the other side of the tobacco guide groove. During the docking of empty cigarette tubes, the shaking drive assembly drives the tobacco guide groove to move horizontally, aligning the pointed tip of the receiving interface with the axis of the empty cigarette tube. Then, the empty tube transfer mechanism is controlled to move forward a short distance, allowing the pointed tip of the receiving interface to enter the empty cigarette tube. Then, the shaking drive assembly drives the tobacco guide groove to move horizontally, aligning the axis of the receiving interface with the axis of the empty cigarette tube. After the empty tube transfer mechanism moves forward to the bottom, it is controlled to return to its original position. The pusher of the pusher module pushes the compacted tobacco out of the tobacco guide groove. At the same time, the empty cigarette tube is pushed out simultaneously, and the tobacco fully enters the empty cigarette tube to form a cigarette, which falls naturally after moving away from the tobacco guide groove.
