Description

Technical Field

[0001] This application relates to the field of waste cigarette processing technology, and in particular to an online recycling system for waste cigarette tobacco from high-speed cigarette making machines. Background Technology

[0002] Cigarette production is a highly automated industrial process. Currently, high-speed cigarette rolling machines can reach speeds of over 12,000 cigarettes per minute. During the operation of these machines, a certain proportion of waste cigarettes is inevitably generated. These waste cigarettes, which fall from the machine, are usually collected in waste cigarette baskets or boxes or transported by conveyor belts. These waste cigarettes are typically rejected by the system during the rolling and filter tipping stages due to physical deformation, appearance defects, excessive or substandard weight caused by machine or operational reasons. These defective products include double-strength cigarettes, cigarettes with interlocking tipping paper, empty cigarettes, bamboo-joint cigarettes, cigarettes with curled tipping paper edges, and cigarettes with broken packs, among others. In the existing cigarette production process, substandard waste cigarettes are usually collected and recycled in a centralized manner. Some workshops use physical crushing and screening to recover tobacco from the substandard waste cigarettes. However, due to the low strength of the tobacco, physical crushing easily breaks the tobacco into pieces, resulting in a very low rate of whole tobacco pieces being recovered. This affects reuse and can only be used at a lower grade or discarded. The tobacco dust formed by the crushing can only be discarded, and the efficiency is low. Summary of the Invention

[0003] The purpose of this application is to provide an online recycling system for waste cigarettes and tobacco shreds from high-speed cigarette making machines. This system can efficiently and completely extract tobacco shreds from waste cigarettes online and directly add them to the original brand for continued use. The tobacco shred breakage is extremely low, which greatly improves the recycling rate of tobacco shreds.

[0004] The online recycling system for waste cigarettes and tobacco shreds from a high-speed cigarette making machine provided in this application adopts the following technical solution: The online recycling system for waste cigarettes and tobacco shreds from high-speed cigarette making machines includes: The vibrating screen, visual screening device, sorting and conveying device and tobacco shred separation device are arranged in sequence. The vibrating screen is used to receive waste cigarettes and separate waste cigarettes from impurities. The visual screening device is used to receive the waste cigarettes transmitted by the vibrating screen and remove non-standard cigarettes from the waste cigarettes. The sorting and conveying device is used to receive the dried waste cigarettes, arrange them in an orderly manner, and convey them to the tobacco shred separation device. The tobacco shred separation device is used to separate tobacco shreds from waste cigarettes.

[0005] Optionally, the tobacco separation device includes a nozzle, a collection chamber, a drive component, and a first conveyor belt. The first conveyor belt is used to receive waste cigarettes conveyed by the sorting and conveying device. The nozzle and the collection chamber are distributed on both sides of the first conveyor belt and are arranged opposite to each other. The drive component is used to drive the nozzle to fit tightly against the filter of the waste cigarette.

[0006] Optionally, it also includes a visual recognition device, which is disposed on one side of the conveyor belt and is used to detect the orientation of the waste cigarettes. The tobacco shred separation device is provided in at least two sets, and the at least two sets of tobacco shred separation devices are disposed in opposite directions and are electrically connected to the visual recognition device.

[0007] Optionally, it also includes a cigarette storage room, which is located above the first conveyor belt and has an open lower end. The cigarette storage room is used to receive the waste cigarettes sorted by the sorting and conveying device and transfer them onto the first conveyor belt. The tobacco storage room is equipped with several partitions, which divide the space inside the tobacco storage room into several flues for accommodating waste cigarettes. Each flue corresponds to a conveyor belt, and waste cigarettes can fall from the flues onto the conveyor belt.

[0008] Optionally, each of the partitions is provided with a guide post at one top end. The cross-section of the guide post has a vertically upward apex angle, which extends axially to form a diversion ridge. Inclined guide surfaces are formed on both sides of the diversion ridge to guide the falling cigarette into the flue.

[0009] Optionally, the conveyor belt is provided with several arc-shaped grooves for accommodating cigarettes.

[0010] Optionally, the sorting and conveying device includes a vibrating conveyor and a second conveyor belt. The vibrating conveyor is used to receive the waste cigarettes after being screened by the visual screening device, and the second conveyor belt is located at the tail end of the vibrating conveyor and is used to convey the vibrated and sorted waste cigarettes to the tobacco separation device.

[0011] Optionally, the sorting and conveying device further includes a third conveyor belt, a fourth conveyor belt, and an arc-shaped guide rail. The third conveyor belt is located at the tail end of the second conveyor belt and is used to receive the waste cigarettes conveyed by the second conveyor belt. The fourth conveyor belt is located below the third conveyor belt and is used to receive the waste cigarettes conveyed by the third conveyor belt and convey the waste cigarettes to the tobacco separation device. Several partitions are fixed on the conveyor belt three, and there is a gap between adjacent partitions two for loading waste cigarettes. The arc-shaped guide rail is located at the end of the conveyor belt three and is used to prevent the cigarettes from leaving the conveyor belt three.

[0012] Optionally, a secondary screening station is also included, where a vibrating screen is also provided. The vibrating screen is positioned corresponding to the tobacco shred separation device and is used to receive the tobacco shreds separated by the tobacco shred separation device. A visual screening device is also provided at the discharge point of the vibrating screen, and the visual screening device is used to screen out impurities mixed in the tobacco shreds.

[0013] Optionally, the vibrating screen is provided with a perforated plate, which divides the internal space of the vibrating screen into upper and lower layers.

[0014] This application has the following technical advantages over the prior art: First, this application has the advantage of high-quality and complete tobacco shred recycling. By setting up a sorting and conveying device to arrange the messy waste cigarettes in an orderly manner, and the tobacco shred separation device uses an air nozzle to blow air tightly against the filter to blow the tobacco shreds out of the waste cigarettes completely. Compared with the traditional physical crushing method, it avoids mechanical damage to the tobacco shreds, greatly reduces the degree of tobacco shreds fragmentation, and ensures the long shred rate and quality of the recycled tobacco shreds.

[0015] Secondly, this application has the advantages of high automation and strong adaptability. By setting up a visual recognition device in conjunction with two sets of tobacco separation devices facing opposite directions, it can detect the orientation of the filter tip of the waste cigarette on the conveyor belt in real time and intelligently adjust the corresponding nozzle to work. There is no need to perform a complicated unified turning process for the cigarette in the early stage, which significantly improves the processing efficiency and the fault tolerance of the equipment.

[0016] Third, this application has the advantage of smooth material transport and is not prone to blockage. By setting a guide column with a diversion ridge at the top of the partition of the tobacco storage, the accumulated tobacco sticks can be effectively diverted to the flues on both sides, avoiding the accumulation and blockage of tobacco sticks at the entrance of the tobacco storage, and ensuring that the tobacco sticks can fall continuously and stably into the arc-shaped groove of the conveyor belt.

[0017] Fourth, this application has the advantage of high recycling purity. By setting up a secondary screening station after tobacco separation, the recycled tobacco is processed again using a vibrating screen and a visual screening device, effectively removing any small impurities or residual paper scraps that may be mixed in, further improving the cleanliness and usability of the final recycled tobacco.

[0018] Fifth, this application promptly recovers and adds the tobacco from the waste cigarettes generated by the high-speed cigarette machine to the production of the brand on the same shift, solving the problems of increased costs and reduced value of tobacco due to centralized processing of waste cigarettes and subsequent reprocessing, and greatly improving the economic benefits of the high-speed cigarette machine.

[0025] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0026] It should be noted that the appendix Figure 1 To be continued Figure 5 The suspended components or equipment shown are all supported by frames during actual installation and use. To simplify the illustrations and highlight the main structure, the frame portion is omitted in the attached drawings.

[0027] Online recycling system for waste cigarettes and tobacco shreds from high-speed cigarette making machines, referring to Figure 1The system includes a vibrating screen 1, a visual screening device 2, a sorting and conveying device 3, and a tobacco separation device 4, which are sequentially arranged next to the high-speed cigarette machine unit and connected to the waste cigarette system of the high-speed cigarette machine unit. The vibrating screen 1 is used to receive the waste cigarettes generated by the high-speed cigarette machine unit 10. The waste cigarettes and impurities are initially separated at the vibrating screen 1. The visual screening device 2 is used to receive the waste cigarettes conveyed by the vibrating screen 1 and remove non-standard cigarettes and impurities from the waste cigarettes. It should be noted that in this embodiment, non-standard cigarettes refer to all non-standard cigarettes in appearance and size, such as cigarettes with continuous exhaust, double cigarettes, residual cigarettes, pure filter tips, broken cigarettes, and cigarettes with severely curled tipping paper. Correspondingly, standard cigarettes refer to standard-sized cigarettes, such as 84mm cigarettes with a filter tip and a regular shape. These waste cigarettes may have fallen due to accidental circumstances, such as insufficient suction caused by blockage of the drum negative pressure hole, foreign objects attached to the drum tobacco groove, or cigarettes falling due to accidental misalignment of the drum position, etc. The sorting and conveying device 3 is used to receive the screened waste cigarettes and arrange them in an orderly manner, and finally convey them to the tobacco separation device 4. The tobacco separation device 4 is used to separate the tobacco from the cigarette paper and filter in the waste cigarettes.

[0028] Regarding vibrating screen 1: Reference Figure 4 The vibrating screen 1 is equipped with a perforated plate 11, which divides the internal space of the vibrating screen 1 into upper and lower layers. The upper layer is used to receive waste cigarettes and relatively intact materials, while the lower layer is used to receive tobacco dust or small debris that falls off the screen. The lower layer has a separate outlet for conveying and carrying away tobacco dust and small debris. In some embodiments, the perforated plate 11 is also equipped with an inverted V-shaped plate 12, which is located directly below the material drop point. The inverted V-shaped plate 12 uses its symmetrical inclined surface to separate and divert the concentrated flow of falling material to both sides, preventing material from accumulating at one point and improving screening efficiency. An elevator 8 is provided between the vibrating screen 1 and the discharge port of the high-speed cigarette machine unit to transport waste cigarettes to the feed port of the vibrating screen 1.

[0029] Regarding visual screening device 2: Reference Figure 2 The visual screening device 2 includes a conveyor belt 21, a camera module 22, and nozzles 23. Material screened by the vibrating screen 1 is conveyed to the visual screening device 2. The camera module 22 is positioned above the conveyor belt 21, visually identifying debris or severely deformed non-standard smoke on the conveyor belt 21 and sending signals to control the nozzles 23 to open. The nozzles 23 blow away the identified non-standard smoke and debris. The visual screening device 2 is also equipped with a guide plate 24, through which the blown-away non-standard smoke and debris are transported to a waste collection point. In this embodiment, the camera module 22 can employ multiple cameras arranged side-by-side, transmitting the collected image information to a terminal device (such as a computer, mobile phone, or other smart device) for image analysis and processing. The analysis results are then used to control the operation of the nozzles 23, blowing away the identified non-standard smoke and debris.

[0030] Regarding the sorting and transmission device 3: Reference Figure 3 The sorting and conveying device 3 includes a vibrating conveyor 31, a second conveyor belt 32, a third conveyor belt 33, a fourth conveyor belt 34, and an arc-shaped guide rail 35. The vibrating conveyor 31 receives the waste cigarettes after being screened by the visual screening device 2, and uses vibration to initially flatten the accumulated cigarettes. Specifically, a hoist transfers the waste cigarettes screened by the visual screening device 2 onto the vibrating conveyor 31. The second conveyor belt 32 is located at the tail end of the vibrating conveyor 31, continuing to convey the vibrated and sorted waste cigarettes forward. In some embodiments, a plurality of partitions 321 are provided above the conveyor belt 32. These partitions 321 are spaced apart and have a certain gap relative to the conveyor belt 32. This gap is greater than the outer diameter of a waste cigarette and less than the length of the waste cigarette. Preferably, the gap is less than one-third of the length of the waste cigarette. The gap is less than the outer diameter of the waste cigarette, preferably less than half the outer diameter, to prevent the waste cigarette from passing under the partitions 321. By providing the partitions 321, the waste cigarette is initially limited to facilitate orderly transport onto the conveyor belt 33. The partitions 321 can be suspended above the conveyor belt 32 via a frame. Figure 1 and attached Figure 3 The middle frame is not shown.

[0031] Conveyor belt 33 is located at the end of conveyor belt 2 32 and is lower than conveyor belt 2. It is used to receive waste cigarettes conveyed by conveyor belt 2. Several partitions 2 36 are fixed on conveyor belt 33. The distance between adjacent partitions 2 36 is greater than the interval between adjacent partitions 3 3. They are used to load waste cigarettes, which are in a horizontally lying position. Conveyor belt 4 34 is located below conveyor belt 33. When waste cigarettes are conveyed to the end of conveyor belt 33, they fall onto conveyor belt 4 34 under the action of gravity. Arc-shaped guide rail 35 is located at the end of conveyor belt 33 and is fixed by a frame (not shown in the figure). There is a gap between arc-shaped guide rail 35 and conveyor belt 33. This gap is smaller than the outer diameter of the waste cigarette to prevent the waste cigarette from leaking out of the gap. The gap also prevents arc-shaped guide rail 35 from affecting conveyor belt 33. Arc-shaped guide rail 35 is used to prevent cigarettes from detaching from conveyor belt 33 during the flipping process, ensuring that they fall accurately into conveyor belt 4 34. Conveyor belt 4 (34) transports waste cigarettes to tobacco separation device 4. Of course, baffles can be installed on the side of conveyor belt 3 (33) to prevent waste cigarettes from falling outside conveyor belt 3 (33) due to inertia when they are transported from conveyor belt 2 (32).

[0032] Regarding tobacco separation device 4 and tobacco storage 6: Reference Figure 4 and Figure 5A tobacco storage chamber 6 is installed above the tobacco separation device 4. The tobacco storage chamber 6 is located above the conveyor belt 44 and its lower end is open. The side walls of the tobacco storage chamber 6 are equipped with side plates to prevent waste cigarettes from falling from the side. Figure 1 , Figure 4 and Figure 5 The side panels of the tobacco storage 6 are omitted to show the internal structure of the tobacco storage 6. The tobacco storage 6 receives the waste cigarettes after they have been sorted by the sorting and conveying device 3. The tobacco storage 6 is equipped with several partitions 61, which divide the space inside the tobacco storage 6 into several flues 62 for accommodating waste cigarettes. After the waste cigarettes fall into the tobacco storage 6, they accumulate inside the tobacco storage 6.

[0033] Each partition 61 has a guide post 63 arranged horizontally at its top. The cross-section of the guide post 63 has an upward-pointing apex angle, which forms a diversion ridge. Inclined guide surfaces are formed on both sides of the diversion ridge. When the waste cigarette falls, the diversion ridge and guide surfaces guide the falling cigarette into the flue 62 on both sides, preventing the cigarette from getting caught on the top of the partition 61 and causing blockage. In some embodiments, the guide post can also be configured to be rotatable, for example, by having a reciprocating rotation device within a 60° range at one end of the guide post.

[0034] The tobacco separation device 4 includes a nozzle 41, a collection chamber 42, a drive component (not shown in the figure), and a conveyor belt 44. The conveyor belt 44 carries and moves the waste cigarettes. The nozzle 41 and the collection chamber 42 are distributed on both sides of the conveyor belt 44 and are arranged opposite each other. In one specific embodiment, the nozzle 41 is connected to an air compressor station, which provides high-pressure gas to the nozzle 41 to achieve gas ejection. The drive component is used to drive the nozzle 41 to move along the axial direction of the cigarette, so that it is in close contact with the filter end of the waste cigarette. The nozzle 41 ejects high-pressure gas, blowing out the tobacco from the cigarette paper of the waste cigarette, and the tobacco enters the collection chamber 42 on the opposite side for collection. In this embodiment, the drive component can be a telescopic motor, a telescopic cylinder, or other components.

[0035] In some embodiments, the conveyor belt 44 is provided with a plurality of arc-shaped grooves 45 for accommodating cigarettes, and a plurality of flues 62 are positioned corresponding to the arc-shaped grooves 45 on the conveyor belt 44, allowing waste cigarettes to fall from the flues 62 into the arc-shaped grooves 45 of the conveyor belt 44. By providing the arc-shaped grooves 45, the occurrence of waste cigarettes moving randomly on the conveyor belt 44 is reduced.

[0036] In some embodiments, a pressure plate 43 is provided above the conveyor belt 44, and the pressure plate 43 corresponds to the position of the air nozzle 41. When the waste cigarette is transported to the position of the air nozzle 41, it is located between the pressure plate 43 and the inner wall of the arc-shaped groove 45. The pressure plate 43 provides secondary positioning and fixation for the waste cigarette to ensure that the air nozzle 41 can stably and tightly adhere to the filter. In some specific embodiments, the distance between the pressure plate 43 and the arc-shaped groove 45 is slightly smaller than the outer diameter of the waste cigarette, so that the waste cigarette will deform when it enters this space, and the waste cigarette will be fixed by friction. In another embodiment, the pressure plate 43 can also be driven by a telescopic cylinder or other driving component to press down on the waste cigarette and fix it.

[0037] In some embodiments, a visual recognition device 5 is provided on one side of the conveyor belt 44. The visual recognition device 5 is used to detect the orientation of the waste cigarettes on the conveyor belt 44 (i.e., whether the filter is on the left or right). At least two sets of tobacco separation devices 4 are provided, with the two sets facing opposite directions (one set of nozzles 41 on the left and one set on the right) and both electrically connected to the visual recognition device 5. When the visual recognition device 5 detects that the cigarette filter is facing left, the set of devices controlling the left nozzle is activated; when it detects that the filter is facing right, the set of devices controlling the right nozzle is activated, thereby achieving automated processing of cigarettes with different orientations. In this embodiment, the visual recognition device 5 can be a camera. The camera transmits the recognized image information to a terminal device (e.g., a computer, mobile phone, or other smart device), and the terminal device analyzes and processes the image, controlling different nozzles 41 to expel air based on the analysis results. The conveyor belt 44 adopts a step-by-step transmission. The conveyor belt 44 moves forward one step and then stops. The pressure plate presses the waste cigarette sticks tightly onto the conveyor belt 44. The air nozzle moves to the filter of the waste cigarette stick and presses it tightly against the filter. The air passage is opened and air is blown into the filter, and the tobacco is blown out.

[0038] Regarding screening station 7: Reference Figure 1 The waste cigarette tobacco shred online recycling system of this embodiment also includes a secondary screening station 7, where a vibrating screen 1 is also installed. This vibrating screen 1 corresponds to the collection bin 42 of the tobacco shred separation device 4 (i.e., it is located below the two collection bins 42) and is used to receive the separated tobacco shreds. The vibrating screen 1 also has a perforated plate structure for screening out fine fragments from the tobacco shreds. Fine fragments fall into the lower layer through the holes and are output through the outlet of the lower layer, while intact tobacco shreds are vibrated and conveyed to the discharge port of the upper layer of the vibrating screen 1.

[0039] The aforementioned visual screening device 2 is also installed at the discharge point of the vibrating screen 1. It further removes any small paper scraps or other impurities that may be mixed in with the tobacco through a camera module and nozzles, ensuring the purity of the recycled tobacco. The purified tobacco is then transported to the next processing station through the suction pipe 9 or directly added to the tobacco hopper of the machine.

[0040] The implementation principle of this application embodiment is as follows: Waste cigarettes generated by the high-speed cigarette making unit first enter the vibrating screen 1 through the elevator 8. The inverted V-shaped plate 12 in the vibrating screen 1 diverts the material, and the perforated plate 11 initially removes small impurities. Subsequently, the waste cigarettes enter the visual screening device 2, where non-standard cigarettes and obvious impurities are removed, and qualified waste cigarettes enter the sorting and conveying device 3. After being flattened by the vibrating conveyor 31 and sorted by the partition 36 of the conveyor belt 33, they enter the cigarette storage 6 in an orderly state. In the cigarette storage 6, the guide column 63 guides the cigarettes... The tobacco flows to each flue 62 and falls into the arc-shaped groove 45 of the conveyor belt 44. The conveyor belt 44 transports the cigarettes through the vision recognition device 5, which identifies the orientation of the cigarette filter. Based on the orientation information, the corresponding drive component pushes the nozzle 41 to press against the filter. High-pressure gas blows the tobacco into the collection chamber 42, and the remaining filter is discharged with the conveyor belt. The collected tobacco enters the re-screening station 7, where it undergoes secondary vibration screening and visual impurity removal to finally obtain high-quality recycled tobacco, which is then promptly recycled and added to the production of cigarettes of the same brand on the machine.

[0041] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
