Description

Technical Field

[0001] This utility model relates to a tobacco recycling device, and more particularly to a mechanism for recycling defective cigarettes and tobacco shreds. Background Technology

[0002] When cigarette factories produce cigarettes, due to defects in raw materials, malfunctions in cigarette rolling equipment, or malfunctions in auxiliary material supply equipment, a certain amount of defective cigarettes will be generated, which have problems such as appearance defects, insufficient fullness and tightness of tobacco, unqualified splicing, and inconsistent draw resistance. In order to improve the utilization rate of raw materials, it is necessary to extract the tobacco from these defective cigarettes without damage and send them to the production line of cigarettes of the same grade for recycling.

[0003] Currently, various methods exist for extracting tobacco from cigarettes, primarily employing either slicing or beating to break down the cigarette. The slicing method uses a straight-line cutting technique, cutting the cigarette paper along its axis. However, if the blade cuts into the adhesive area, small strips of paper are created that cannot be removed, affecting the purity of the tobacco. Furthermore, the paper cannot fully unroll after straight-line cutting, making subsequent tobacco extraction difficult and hindering complete recycling. The beating method uses impacts between cigarettes to detach the tobacco, but the tobacco remains stretched within the cigarette paper packaging and cannot detach completely. Therefore, neither method achieves optimal results. Utility Model Content

[0004] This utility model provides a mechanism for recycling tobacco shreds from defective cigarettes, solving the problem of recycling tobacco shreds without damage by spirally cutting the outer surface of cigarettes. The technical solution is as follows:

[0005] A defective cigarette tobacco recycling facility includes:

[0006] The structure of the tobacco processing equipment is as follows: the upper part is equipped with a tobacco feeding and conveying module, a tobacco cutting module, and a tobacco paper unfolding module, from front to back. The lower part is equipped with a tobacco separation module. The tobacco feeding and conveying module is located directly below the defective tobacco output port.

[0007] Cigarette feeding, sorting and conveying module: Receives defective cigarettes from the defective cigarette output port, adjusts the orientation of both ends of the defective cigarettes through the linear vibration mode of the straight vibrator and the special curve of the cigarette sorting plate, the adjustment direction is the forward direction driven by the straight vibrator, and then sends the adjusted defective cigarettes into the cigarette cutting module through the cigarette conveying plate.

[0008] Cigarette cutting module: The conveyed cigarettes rotate via a rotating component, and then the cutting component, which is placed obliquely on the rotating component, rotates to spirally cut the cigarette paper of the defective cigarettes.

[0009] Cigarette paper unfolding module: The tobacco shreds and cigarette paper are separated by a flexible roller with meshing motion;

[0010] Tobacco shred separation module: Taking advantage of the small size and dispersed nature of tobacco shreds, the separated tobacco shreds are collected into the tobacco shred collection material frame using the screening principle, and the remaining tobacco paper waste is collected into the waste collection bin.

[0011] The cigarette feeding, sorting, and conveying module includes a vibrator placement plate, a vibrator, a cigarette sorting plate, and a cigarette conveying plate. The vibrator placement plate is fixedly installed on the tobacco equipment frame, and the vibrator is fixed on the vibrator placement plate. Two sets of vibrators are provided, which are respectively installed on the cigarette sorting plate and the cigarette conveying plate. The upper surface of the cigarette sorting plate and the cigarette conveying plate is sinusoidal wave-shaped, and the cigarette sorting plate is provided with multiple cigarette sorting pins.

[0012] The cigarette feeding and conveying module is equipped with a cigarette conveying module baffle plate. On both sides of the cigarette conveying plate, there are cigarette blockage cleaning modules installed on the cigarette conveying module baffle plates. When the cigarette conveying plate is blocked, the cigarette blockage cleaning modules drive the cigarette blockage cleaning brush to clean all the cigarettes on the cigarette conveying plate.

[0013] The cigarette cutting module includes a cutting module placement plate, a meshing shaft assembly, a rotation assembly, and a cutting assembly. The cutting module placement plate is fixed on the tobacco equipment structure. The meshing shaft assembly, the rotation assembly, and the cutting assembly are fixedly installed on the top of the cutting module placement plate. The cutting assembly is located above the rotation assembly. The meshing shaft assembly is located between the cutting assembly and the cigarette conveying plate of the cigarette feeding, sorting, and conveying module.

[0014] The meshing shaft assembly includes an upper feed meshing shaft, a lower feed meshing shaft, and a feed power output motor. The upper feed meshing shaft and the lower feed meshing shaft are fixed on the cutting module placement plate. The upper feed meshing shaft is driven by the feed power output motor, which in turn drives the lower feed meshing shaft to perform meshing motion. The upper feed meshing shaft is located above the lower feed meshing shaft. The lower feed meshing shaft is provided with multiple evenly arranged notches, which correspond to the sinusoidal wave-shaped valley bottom of the cigarette conveying plate.

[0015] The self-rotating assembly includes a self-rotating roller, a self-rotating roller gearbox, and a self-rotating power output motor. There are multiple self-rotating rollers, and the two ends of each self-rotating roller are connected to the self-rotating roller gearbox. The self-rotating roller gearbox is driven by the self-rotating power output motor to realize the same-direction rotation of multiple self-rotating rollers.

[0016] The cutting assembly includes a cutting mounting base, a cutting feed shaft, a cutting shaft, a cutting blade, and a cutting power motor. The cutting feed shaft and the cutting shaft are both fixed above the rotating roller by the cutting mounting base and are arranged obliquely. The cutting feed shaft is located between the cutting shaft and the meshing shaft assembly and is used to drive the axial cigarette on the rotating roller to move towards the cutting shaft. The cutting shaft is equipped with a cutting blade, which cuts the cigarette paper of the cigarette.

[0017] The tobacco paper unfolding module includes an unfolding module placement plate, a cutting tobacco stick baffle, a flexible roller shaft, and a tobacco paper unfolding motor. The cutting tobacco stick baffle is fixed to the tobacco equipment structure through the unfolding module placement plate, and wraps around and fixes the meshing flexible roller shaft, which is driven by the tobacco paper unfolding motor.

[0018] The tobacco separation module includes a tobacco separation guide cylinder, a tobacco inlet baffle, a guide cylinder motor, a tobacco collection material frame, a waste paper chute, a waste paper conveyor belt, a waste collection bin, and an unfolding cigarette chute. The inlet of the unfolding cigarette chute is located below the cigarette unfolding module, and the outlet extends into the tobacco separation guide cylinder. The tobacco separation guide cylinder is rotatably fixed to the tobacco equipment frame, with one end passing through the outlet of the unfolding cigarette chute and the other end connected to the waste paper chute. It is driven by the guide cylinder motor, and a tobacco inlet baffle is located on the outside of the tobacco separation guide cylinder. The tobacco inlet baffle covers the tobacco separation guide cylinder, leaving only one outlet directly below it. A tobacco collection material frame is placed directly below the outlet to collect the separated tobacco. A waste paper conveyor belt is located below the waste paper chute, and a waste collection bin is located at the other end of the waste paper conveyor belt.

[0019] The cross-section of the tobacco shred separation guide tube is a hexagonal prism, and each face of the hexagonal prism has a large number of waist-shaped holes. The inside of the tobacco shred separation guide tube is equipped with a guide plate. The tobacco shreds can be separated through the waist-shaped holes, while the remaining tobacco paper waste cannot pass through the waist-shaped holes and can only be conveyed forward through the guide plate in the tobacco shred separation guide tube to reach the waste paper chute.

[0020] The defective cigarette and tobacco recycling mechanism uses a cigarette feeding and conveying module to vibrate and align horizontally placed cigarettes axially. A cigarette cutting module then spirally cuts the cigarette surface, followed by flexible rollers from a cigarette paper unfolding module to extract the tobacco from the inside of the cigarette. Finally, a tobacco separation module separates the tobacco from waste through different outlets, achieving tobacco recycling. Because of the spiral cutting and controllable cutting distance, the recycled tobacco has high purity, a high rate of whole tobacco strands, and is virtually free of waste and impurities. This mechanism does not involve heating or ventilation equipment during operation, and the moisture content and other indicators of the recycled tobacco remain essentially unchanged, allowing for direct use without downgrading.

[0025] Figure 5 This is a schematic diagram of the structure of the tobacco separation module. Detailed Implementation

[0026] like Figure 1 As shown, the defective cigarette and tobacco recycling mechanism includes a defective cigarette output port 1, a tobacco equipment structure 2, a cigarette feeding and conveying module 3, a cigarette cutting module 4, a tobacco paper unfolding module 5, and a tobacco separation module 6. The cigarette feeding and conveying module 3, the cigarette cutting module 4, and the tobacco paper unfolding module 5 are sequentially installed above the tobacco equipment structure 2 from front to back, while the tobacco separation module 6 is installed below it. The defective cigarette output port 1 is located above the cigarette feeding and conveying module 3, and the inlet of the tobacco separation module 6 is located below the tobacco paper unfolding module 5, while the outlet is located below the cigarette feeding and conveying module 3. The defective cigarette output port 1 serves as the outlet for defective cigarettes on the cigarette production line, allowing the defective cigarette and tobacco recycling mechanism to directly connect to the cigarette production line without secondary transportation. The cigarette feeding and conveying module 3, the cigarette cutting module 4, the tobacco paper unfolding module 5, and the tobacco separation module 6 are respectively connected and fixed to the tobacco equipment structure 2 to form the main body of the equipment.

[0027] like Figure 2 As shown, the cigarette feeding, sorting and conveying module 3 includes a vibrator placement plate 301, a cigarette conveying module barrier plate 302, a vibrator 303, a cigarette sorting plate 304, a cigarette sorting pin 305, an axial cigarette 306, a cigarette conveying plate 307, a clogged cigarette cleaning module 308, a clogged cigarette cleaning brush 309, and a vibrator damping pad 310.

[0028] The straight vibrator placement plate 301 has two groups, a front group and a rear group, which are fixedly installed on the tobacco processing equipment frame 2. A straight vibrator 303 is installed on top of the straight vibrator placement plate 301, and a straight vibrator damping pad 310 is provided between the straight vibrator 303 and the straight vibrator placement plate 301. The straight vibrator 303 also has two groups, a front group and a rear group. A tobacco stick sorting plate 304 is also installed on top of the straight vibrator placement plate 301 of the front group, and the straight vibrator 303 of the front group is fixed below the tobacco stick sorting plate 304. A tobacco stick conveying plate 307 is also installed on top of the straight vibrator placement plate 301 of the rear group, and the straight vibrator 303 of the rear group is fixed below the tobacco stick conveying plate 307. The upper surfaces of the cigarette sorting plate 304 and the cigarette conveying plate 307 are sinusoidal wave-shaped and at the same height. The defective cigarettes that fall onto the cigarette sorting plate 304 from the defective cigarette output port 1 are turned on the cigarette sorting plate 304 by the cigarette sorting pin 305 to form axial cigarettes 306. The axial cigarettes 306 can be conveyed forward by a straight vibrator at the bottom of the two plates (cigarette sorting plate 304 and cigarette conveying plate 307).

[0029] Furthermore, the cigarette sorting plate 304 is provided with multiple cigarette sorting pins 305. In this embodiment, there are multiple cigarette sorting pins 305, divided into several groups, with multiple pins evenly distributed in each group, arranged evenly from left to right on the cigarette sorting plate 304. When a defective cigarette falls from the defective cigarette output port 1 and lands on the cigarette sorting plate 304, if there are cigarettes lying horizontally on it, they will be blocked by the cigarette sorting pins 305. Then, through the vibration of the straight vibrator, the horizontal cigarettes are converted into axial cigarettes 306 for conveying, and they are then conveyed to the cigarette conveying plate 307.

[0030] Furthermore, the cigarette feeding and conveying module 3 is equipped with cigarette conveying module baffles 302, which are divided into a first cigarette conveying module baffle and a second cigarette conveying module baffle. The first cigarette conveying module baffle is installed on the left and right sides and the front end of the cigarette feeding plate 304, and the lower part of the first cigarette conveying module baffle is fixedly installed on the front group's vibrator 303; the second cigarette conveying module baffle is installed on the left and right sides of the cigarette conveying plate 307, and the lower part of the second cigarette conveying module baffle is fixedly installed on the rear group's vibrator 303. The cigarette conveying module baffles 302 are used to block cigarettes and prevent them from seeping out from the sides of the cigarette feeding plate 304 and the cigarette conveying plate 307 during movement. The cigarette conveying plate 307 is equipped with a blocked cigarette cleaning module 308, which is installed on the barrier plate of the second cigarette conveying module. When the cigarette conveying plate 307 is blocked, the blocked cigarette cleaning module 308 drives the blocked cigarette cleaning brush 309 to clean all the cigarettes on the cigarette conveying plate 307 and relieve the blockage.

[0031] The clogged cigarette cleaning module 308 includes a linear module, an auxiliary guide rail, a connecting rod, and a cleaning drive motor. The linear module and the auxiliary guide rail are respectively installed on the left and right sides of the second cigarette conveying module baffles of the cigarette conveying plate 307. A cleaning drive motor is installed at one end of the linear guide rail, which is equipped with a first slider that can move back and forth along the linear guide rail under the drive of the cleaning drive motor. A second slider is installed on the auxiliary guide rail, which can move back and forth along the auxiliary guide rail. The first and second sliders are fixedly connected by a connecting rod, on which a clogged cigarette cleaning brush 309 is installed.

[0032] The lower edge of the blocked cigarette cleaning brush 309 does not affect the axial movement of the cigarette 306 along the sinusoidal wave valley of the cigarette sorting plate 304 and the cigarette conveying plate 307. When the cigarette is blocked, causing it to be located at the top of the sinusoidal wave valley, it will be pushed back to the cigarette sorting plate 304 by the blocked cigarette cleaning brush 309.

[0033] like Figure 3 As shown, the cigarette cutting module 4 includes a cutting module placement plate 401, a meshing shaft assembly, a rotation assembly, and a cutting assembly. The cutting module placement plate 401 is fixed on the tobacco equipment structure 2. The meshing shaft assembly, the rotation assembly, and the cutting assembly are fixedly installed on top of the cutting module placement plate 401. The cutting assembly is located above the rotation assembly, and the meshing shaft assembly is located between the cutting assembly and the cigarette conveying plate 307.

[0034] The meshing shaft assembly includes an upper feed meshing shaft 402, a lower feed meshing shaft 403, and a feed power output motor 404. The upper feed meshing shaft 402 and the lower feed meshing shaft 403 are fixed on the cutting module placement plate 401. The feed power output motor 404 drives the upper feed meshing shaft 402, which in turn drives the lower feed meshing shaft 403 to perform meshing motion. When the axial cigarette 306 is brought along by the cigarette conveying plate 307, the motion is transmitted to the rotation component through the meshing motion of the two shafts. The upper feed meshing shaft 402 is located above the lower feed meshing shaft 403. The lower feed meshing shaft 403 has multiple evenly arranged notches, which correspond to the sinusoidal wave-shaped valley bottom of the cigarette conveying plate 307.

[0035] The rotation assembly includes rotating rollers 405, rotating roller gearboxes 406, and a rotation power output motor 407. Multiple rotating rollers 405 are provided, with both ends of each roller connected to the rotating roller gearboxes 406. The rotating roller gearboxes 406 are driven by the rotation power output motors 407, enabling the multiple rotating rollers 405 to rotate in the same direction. A meshing shaft assembly feeds the axial cigarette stick 306 to the rotating rollers 405. As the rotating rollers 405 rotate, the axial cigarette stick 306 rotates in the same direction as the rollers 405. Furthermore, the rotating roller gearboxes 406 include multiple sets of sequentially arranged rotating gears of the same size and shape. Auxiliary gears are provided between adjacent rotating gears, enabling the rotating gears at both ends to rotate in the same direction. The center of each rotating gear is fixed with the shaft of a rotating roller. One of the rotating gears is driven by a self-rotation power output motor 407, which in turn enables the other rotating gears to rotate in the same direction, thereby enabling the rotating gears to drive the rotating roller to rotate.

[0036] The cutting assembly includes a cutting mounting base 408, a cutting feed shaft 409, a cutting shaft 410, a cutting blade 411, and a cutting power motor 412. Both the cutting feed shaft 409 and the cutting shaft 410 are fixed above the rotating roller 405 by the cutting mounting base 408 and are arranged obliquely. The cutting feed shaft 409 is located between the cutting shaft 410 and the meshing shaft assembly, and is used to drive the axial cigarette stick 306 on the rotating roller 405 to move towards the cutting shaft 410. The cutting blade 411 is mounted on the cutting shaft 410, and cuts the cigarette paper of the cigarette stick by the cutting blade 411.

[0037] The cutting feed shaft 409 and the cutting shaft 410 are driven by a cutting power motor 412, achieving co-directional movement. Furthermore, both ends of the cutting feed shaft 409 are mounted on the cutting fixture 408 via bearings, with one end extending and equipped with a first gear; both ends of the cutting shaft 410 are mounted on the cutting fixture 408 via bearings, with one end extending and equipped with a second gear, and the other end is driven by the cutting power motor 412. The first gear and the second gear are connected by a chain. When the cutting power motor 412 drives the cutting shaft 410 to rotate, the cutting shaft 410 drives the first gear to rotate in the same direction via the second gear and the chain, thereby driving the cutting feed shaft 409 to rotate in the same direction.

[0038] In use, the cigarette rotates on two rotating rollers 405 through friction. The cigarette on the two rotating rollers 405 is then pushed to the cutting assembly by a subsequent axial cigarette 306, which travels by the meshing motion of the two shafts. After the cigarette reaches directly below the cutting feed shaft 409 and the cutting shaft 410, its co-directional motion causes the rotating cigarette to be helically cut.

[0039] like Figure 4As shown, the tobacco paper unfolding module 5 includes an unfolding module placement plate 501, a cutting tobacco stick baffle 502, a flexible roller shaft 503, and a tobacco paper unfolding motor 504. The unfolding module placement plate 501 is fixed on the tobacco equipment frame 2. The cutting tobacco stick baffle 502 is connected to the unfolding module placement plate 501 and wraps around and fixes the flexible roller shaft 503. Both ends of the flexible roller shaft 503 are mounted on the cutting tobacco stick baffle 502 through bearings. There are two flexible roller shafts 503 that mesh with each other. One flexible roller shaft 503 is driven by the tobacco paper unfolding motor 504 and has a third gear at one end. The other flexible roller shaft 503 has a fourth gear at the same end. The third gear drives the fourth gear to rotate, realizing the meshing motion of the two flexible roller shafts 503.

[0040] In use, the axial cigarette stick 306 is spirally cut into cut cigarette sticks 505 by the cigarette stick cutting module 4. After the cut cigarette sticks 505 are cut, they fall onto the flexible roller shafts 503. The two pairs of flexible roller shafts 503 beat the cut cigarette sticks 505 at different speeds, so that the tobacco shreds and cigarette paper waste are separated. The cigarette paper unfolding motor 504 drives the flexible roller shafts 503 to achieve their meshing motion.

[0041] like Figure 5 As shown, the tobacco separation module 6 includes a tobacco separation guide tube 601, a tobacco inlet baffle 602, a guide tube motor 603, a tobacco collection material frame 604, a waste paper chute 605, a waste paper conveyor belt 606, a waste collection bin 607, and an unfolding cigarette chute 608.

[0042] The cigarette unfolding chute 608 is connected to the cigarette paper unfolding module 5, with its inlet located below the cigarette paper unfolding module 5 and its outlet extending into the tobacco shred separation guide tube 601. One end of the tobacco shred separation guide tube 601 passes through the outlet of the cigarette unfolding chute 608, while the other end is rotatably fixed to the tobacco shred equipment frame 2 and driven by the guide tube motor 603. A tobacco shred inlet baffle 602 is provided on the outer side of the tobacco shred separation guide tube 601. The tobacco shred inlet baffle 602 covers the tobacco shred separation guide tube 601, leaving only one outlet directly below it. A tobacco shred collection material frame 604 is placed directly below the outlet to collect the separated tobacco shreds.

[0043] In use, the cut cigarette stick 505, after passing through the cigarette paper unfolding module 5, basically achieves the separation of tobacco shreds and waste. The tobacco shreds are then transferred by the unfolding cigarette chute 608 into the tobacco shred separation guide cylinder 601, which is rotated by the guide cylinder motor 603. The cross-section of the tobacco shred separation guide cylinder 601 is a hexagonal prism, and each face of the hexagon has a large number of waist-shaped holes. The tobacco shreds can be separated through these waist-shaped holes, while the remaining cigarette paper waste cannot pass through the waist-shaped holes and can only be transferred forward through the guide plate in the tobacco shred separation guide cylinder 601. Finally, the waste paper waste exits the tobacco shred separation guide cylinder 601, enters the waste paper conveyor belt 606 via the waste paper chute 605, continues to transfer the waste paper forward, and is finally collected in the waste collection bin 607 for centralized processing.

[0044] This invention has the following advantages: it uses a novel spiral cutting technology for cigarettes, and the cutting blade size is controllable during the cutting process, so the tobacco is basically not broken and the tobacco will not be contaminated by cigarette waste, so the purity of the tobacco is extremely high; the equipment does not contain wind or heat equipment during operation, so the moisture content of the recycled tobacco remains basically unchanged.

[0045] This device occupies a small area and has a low working height, allowing it to be directly connected to the defective cigarette outlet on the cigarette production line for real-time processing. This avoids waste caused by mixing high-end and low-end cigarettes. The device operates fully automatically, freeing up manual labor, and is therefore highly practical.

[0046] In summary, the tobacco shreds recovered by this equipment have normal moisture content, high whole shred rate, and high purity. They can be used directly without downgrading and have a high degree of automation, which is of great significance for tobacco factories to reduce waste and lower costs.

[0047] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
