Description

Technical Field

[0001] This invention relates to the field of tobacco equipment technology, and in particular to a tobacco shred recycling device and recycling method. Background Technology

[0002] Currently, tobacco production sites primarily use vibration screening to recover tobacco shreds from residual cigarettes. However, during the recovery process, vibration cannot effectively remove the tobacco shreds from the innermost part of the cigarette, especially for slim cigarettes. This results in a low tobacco shred recovery rate. Furthermore, using vibration to recover tobacco shreds from residual cigarettes significantly increases the rate of broken tobacco shreds, leading to persistently high tobacco shred consumption per carton. Moreover, current methods cannot directly recover cigarettes with flavor capsules; the filter must be manually removed before tobacco shred recovery can begin. This process is labor-intensive and inefficient.

[0003] Therefore, there is an urgent need to propose a solution to this problem. Summary of the Invention

[0004] The first objective of this invention is to provide a tobacco shred recycling device to solve the problems of low tobacco shred recycling rate and high rate of recycled broken shreds in the prior art.

[0005] The second objective of this invention is to provide a recycling method for improving the tobacco shred recycling rate and reducing the rate of recycled broken shreds.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A tobacco recycling device includes a cigarette conveying wheel and a first driving component. The first driving component is kinetically connected to the cigarette conveying wheel. The cigarette conveying wheel has multiple grooves spaced apart along its circumference to accommodate cigarettes to be recycled provided by an upstream process. The tobacco recycling device also includes a color difference detection sensor capable of detecting the orientation of the filter tip of the cigarette to be recycled in the groove. The tobacco recycling device further includes a first blowing mechanism and a second blowing mechanism. The first blowing mechanism and the second blowing mechanism are spaced apart along the circumference of the cigarette conveying wheel. Both the first blowing mechanism and the second blowing mechanism can fix the filter tip of the corresponding cigarette to be recycled in the groove and blow out the tobacco from the cigarette to be recycled. The tobacco recycling device also includes a central controller. The first driving component, the color difference detection sensor, the first blowing mechanism, and the second blowing mechanism are all coupled to the central controller. The central controller can control the first driving component to rotate intermittently and can control the first blowing mechanism or the second blowing mechanism to operate according to the orientation of the filter tip of the cigarette to be recycled.

[0008] In some embodiments, the first blowing mechanism includes a first ejector pin, a second drive member, and a first air nozzle. The first ejector pin is mounted on the movable end of the second drive member. The second drive member can drive the first ejector pin to press against the radial side of the filter of the cigarette to be recycled. The first air nozzle can be connected to a positive pressure air source and can abut against one axial end of the filter of the cigarette to be recycled. The first air nozzle can blow out the tobacco from the cigarette to be recycled.

[0009] In some embodiments, the second blowing mechanism includes a second ejector pin, a third driving member, and a second air nozzle. The second ejector pin is mounted on the movable end of the third driving member. The third driving member can drive the second ejector pin to press against the radial side of the filter of the cigarette to be recycled. The second air nozzle can be connected to a positive pressure air source and can abut against one axial end of the filter of the cigarette to be recycled. The second air nozzle can blow out the tobacco from the cigarette to be recycled.

[0010] In some embodiments, the tobacco recycling device further includes a tobacco storage component having a tobacco storage chamber for storing the cigarettes to be recycled. The lower end of the tobacco storage component has an opening, and the cigarette conveying wheel is located below the opening, allowing the cigarettes to be recycled in the tobacco storage chamber to fall into the wheel groove through the opening.

[0011] In some embodiments, the first blowing mechanism is located at one end of the cigarette conveying wheel along its own axial direction, and the second blowing mechanism is located at the other end of the cigarette conveying wheel along its own axial direction.

[0012] In some embodiments, the tobacco recycling device further includes a numbering mechanism, which includes a metal marker and an origin sensor. The metal marker is disposed on the tobacco conveying wheel and corresponds to one of the wheel grooves. The origin sensor is spaced apart on the side of the tobacco conveying wheel and is coupled to the central controller. The origin sensor can sense the metal marker. After the origin sensor senses the metal marker, the central controller can set the number of the wheel groove corresponding to the metal marker to 1. After the tobacco conveying wheel rotates by a preset angle W, the central controller can increment the number of the wheel groove behind the wheel groove corresponding to the metal marker by 1, where W = 360° / N, and N is the number of wheel grooves.

[0013] In some embodiments, the tobacco recycling device further includes a feeding detection sensor, which can detect whether the cigarette to be recycled exists in the wheel groove.

[0014] A recycling method, using the aforementioned tobacco recycling device, includes the following steps:

[0015] S1. Control the cigarette conveying wheel to rotate by a preset angle, and number the wheel grooves sequentially;

[0016] S2. Determine whether the target wheel groove is located at the inspection station;

[0017] S3. If the target wheel groove is located at the detection station, read the detection result of the color difference detection sensor to obtain the orientation of the filter of the cigarette to be recycled, and match the orientation of the filter of the cigarette to be recycled with the number of the target wheel groove, and return to step S1. If the target wheel groove is not located at the detection station, determine whether the target wheel groove is located at the first blowing station.

[0018] S4. If the target wheel groove is located at the first blowing station, determine whether the filter of the cigarette to be recycled in the target wheel groove is facing the first direction. If yes, the first blowing mechanism is activated. After the activation is completed, the number of the target wheel groove is cleared and the process returns to step S1. If no, the process returns directly to step S1. If the target wheel groove is not located at the first blowing station, determine whether the target wheel groove is located at the second blowing station. If yes, determine whether the filter of the cigarette to be recycled in the target wheel groove is facing the second direction. If the filter of the cigarette to be recycled in the target wheel groove is facing the second direction, the second blowing mechanism is activated. After the activation is completed, the process returns to step S1. If the filter of the cigarette to be recycled in the target wheel groove is not facing the second direction, the process returns to step S1. The second direction is the opposite direction of the first direction.

[0019] In some embodiments, before numbering the wheel grooves sequentially in step S1, the method further includes: calibrating the cigarette delivery wheel to zero.

[0020] In some embodiments, in step S4, determining whether the filter of the cigarette to be recycled in the target wheel groove is facing the first direction specifically includes: obtaining the detection result of the color difference detection sensor corresponding to the number of the target wheel groove;

[0021] Determining whether the filter of the cigarette to be recycled in the target wheel groove is facing the second direction specifically includes: obtaining the detection result of the color difference detection sensor corresponding to the number of the target wheel groove.

[0022] The beneficial effects of this invention are:

[0023] This invention proposes a tobacco shred recycling device, comprising a tobacco conveying wheel and a first driving component. The first driving component is kinetically connected to the tobacco conveying wheel. The tobacco conveying wheel has multiple grooves spaced apart along its circumference, which are used to accommodate tobacco shreds to be recycled provided by the previous process. The tobacco shred recycling device also includes a color difference detection sensor, which can detect the orientation of the filter tip of the tobacco shred to be recycled in the groove. The tobacco shred recycling device also includes a first blowing mechanism and a second blowing mechanism, which are spaced apart along the circumference of the tobacco conveying wheel. Both the first blowing mechanism and the second blowing mechanism can fix the filter tip of the tobacco shred to be recycled in the corresponding groove and blow out the tobacco shreds from the tobacco shred to be recycled. The tobacco shred recycling device also includes a central controller. The first driving component, the color difference detection sensor, the first blowing mechanism, and the second blowing mechanism are all coupled to the central controller. The central controller can control the first driving component to rotate intermittently and can control the operation of the first blowing mechanism or the second blowing mechanism according to the orientation of the filter tip of the tobacco shred to be recycled. Understandably, when it is necessary to recycle tobacco from the cigarettes to be recycled in the wheel groove, the central controller controls the first drive unit to rotate intermittently. Each rotation allows the color difference detection sensor to detect the filter orientation of a cigarette to be recycled in one wheel groove. After obtaining the filter orientation of the cigarette to be recycled, the color difference detection sensor uploads the filter orientation information to the central controller. The central controller sends instructions to the first blowing mechanism and the second blowing mechanism, causing the first blowing mechanism to blow tobacco from the cigarettes to be recycled with the filter facing one end of the cigarette conveying wheel axis, and causing the second blowing mechanism to blow tobacco from the cigarettes to be recycled with the filter facing the other end of the cigarette conveying wheel axis. This is the tobacco recycling device proposed in this embodiment. The first blowing mechanism and the second blowing mechanism blow out the tobacco from their respective cigarettes to be recycled. Compared with the prior art's method of removing tobacco by vibration, the tobacco deep in the cigarettes to be recycled can also be thoroughly blown out, improving the tobacco recycling rate. Moreover, the method of blowing tobacco has a low breakage rate, avoiding tobacco waste. In addition, after detecting the filter orientation of the cigarettes to be recycled in the wheel groove, the first blowing mechanism and the second blowing mechanism are used to fix the filter and blow the tobacco for the two different filter orientations. There is no need to make the filter orientation of the cigarettes to be recycled in the wheel groove consistent, nor is it necessary to remove the filter, which greatly improves the tobacco recycling efficiency and reduces the labor intensity of personnel.

[0024] The present invention proposes a recycling method that uses a tobacco shred recycling device, which improves the tobacco shred recycling rate and reduces the recycling breakage rate. Attached Figure Description

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0032] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0033] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0034] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0035] On the one hand, this embodiment proposes a tobacco shred recycling device to solve the problems of low tobacco shred recycling rate and high rate of recycled broken shreds in the prior art.

[0036] like Figures 1-2 As shown, this embodiment proposes a tobacco shred recycling device, including a tobacco conveying wheel 1 and a first driving member 2. The first driving member 2 is connected to the tobacco conveying wheel 1. The tobacco conveying wheel 1 has multiple grooves 11 spaced apart along its circumference. The grooves 11 are used to accommodate the tobacco shreds to be recycled provided by the previous process. The tobacco shred recycling device also includes a color difference detection sensor 3, which can detect the filter orientation of the tobacco shreds to be recycled in the grooves 11. The tobacco shred recycling device also includes a first blowing mechanism 4 and a second blowing mechanism 5. Along the circumference of the tobacco conveying wheel 1, the first blowing mechanism 4 and the second blowing mechanism 5... Two blowing mechanisms 5 are arranged at intervals. The first blowing mechanism 4 and the second blowing mechanism 5 can fix the filter of the cigarette to be recycled in the corresponding wheel groove 11 and blow out the tobacco in the cigarette to be recycled. The tobacco recycling device also includes a central controller. The first drive unit 2, the color difference detection sensor 3, the first blowing mechanism 4 and the second blowing mechanism 5 are all coupled to the central controller (coupling includes electrical connection and signal connection). The central controller can control the first drive unit 2 to rotate intermittently and can control the first blowing mechanism 4 or the second blowing mechanism 5 to operate according to the orientation of the filter of the cigarette to be recycled.

[0037] Understandably, when it is necessary to recycle tobacco from the cigarettes to be recycled in the groove 11, the central controller controls the first drive unit 2 to rotate intermittently. Each time it rotates, the color difference detection sensor 3 can detect the filter orientation of a cigarette to be recycled in the groove 11. After obtaining the filter orientation of the cigarette to be recycled, the color difference detection sensor 3 uploads the filter orientation information to the central controller. The central controller sends instructions to the first blowing mechanism 4 and the second blowing mechanism 5, so that the first blowing mechanism 4 blows tobacco from the cigarettes to be recycled with the filter facing one end of the cigarette conveying wheel 1, and the second blowing mechanism 5 blows tobacco from the cigarettes to be recycled with the filter facing the other end of the cigarette conveying wheel 1. That is, the tobacco recycling device proposed in this embodiment blows the tobacco out of the corresponding cigarettes to be recycled. Compared with the prior art of removing tobacco by vibration, the tobacco deep in the cigarettes to be recycled can also be thoroughly blown out, improving the tobacco recycling rate. Moreover, the method of blowing tobacco has a low breakage rate, avoiding tobacco waste. In addition, after detecting the filter orientation of the cigarettes to be recycled in the wheel groove 11, the first blowing mechanism 4 and the second blowing mechanism 5 are used to fix the filter and blow the tobacco for the two different filter orientations. There is no need to make the filter orientation of the cigarettes to be recycled in the wheel groove 11 consistent, nor is it necessary to remove the filter. This greatly improves the tobacco recycling efficiency and reduces the labor intensity of personnel.

[0038] It is worth noting that the color difference detection sensor 3 is existing technology. For example, the color difference detection sensor 3 can preset the characteristic color of the filter tip through a teaching method. When the cigarette arrives at the detection station, the color difference detection sensor 3 determines the orientation of the cigarette based on the reflected light spectrum. If it is the filter tip end, it outputs a high level; otherwise, it outputs a low level. This is used to calibrate the filter tip orientation of the cigarettes to be recycled in different grooves 11. The specific operating principle of the color difference detection sensor 3 will not be elaborated in this embodiment.

[0039] For example, the first driving element 2 is a servo motor to improve driving flexibility.

[0040] In some optional embodiments, the first blowing mechanism 4 includes a first ejector pin 41, a second drive member 42, and a first air nozzle 43. The first ejector pin 41 is mounted on the movable end of the second drive member 42. The second drive member 42 can drive the first ejector pin 41 to press against the radial side of the filter of the cigarette to be recycled. The first air nozzle 43 can be connected to a positive pressure air source and can abut against one axial end of the filter of the cigarette to be recycled. The first air nozzle 43 can blow out the tobacco from the cigarette to be recycled.

[0041] Understandably, when it is necessary to blow tobacco out of the cigarette to be recycled, the movable end of the second drive member 42 drives the first pin 41 to press against the filter of the cigarette to be recycled from the radial direction. The positive pressure gas source supplies positive pressure gas to the first air nozzle 43, and the first air nozzle 43 blows air into the cigarette to be recycled through the axial end of the filter of the cigarette to be recycled, thereby blowing out the tobacco in the cigarette to be recycled. The structure is simple and the principle is reliable, which improves the structural rationality of the tobacco recycling device.

[0042] For example, the first blowing mechanism 4 further includes a first mounting member 44, on which a second mounting member 45 is detachably mounted. The second mounting member 45 can be repositioned along the axial direction of the cigarette conveying wheel 1 on the first mounting member 44, and the first air nozzle 43 is mounted on the second mounting member 45. This arrangement allows for adjustment of the distance between the first air nozzle 43 and the filter of the cigarette to be recycled, thereby accommodating cigarettes of different sizes to be recycled and improving the structural rationality of the tobacco recycling device.

[0043] In some optional embodiments, the second blowing mechanism 5 includes a second ejector pin, a third drive member 51, and a second air nozzle 52. The second ejector pin is mounted on the movable end of the third drive member 51. The third drive member 51 can drive the second ejector pin to press against the radial side of the filter of the cigarette to be recycled. The second air nozzle 52 can be connected to a positive pressure air source and can abut against one axial end of the filter of the cigarette to be recycled. The second air nozzle 52 can blow out the tobacco from the cigarette to be recycled.

[0044] Understandably, when it is necessary to blow tobacco out of the cigarette to be recycled, the movable end of the third drive member 51 drives the second pin to press against the filter of the cigarette to be recycled from the radial direction. The positive pressure gas source supplies positive pressure gas to the second air nozzle 52, and the second air nozzle 52 blows air into the cigarette to be recycled through the axial end of the filter of the cigarette to be recycled, thereby blowing out the tobacco in the cigarette to be recycled. The structure is simple and the principle is reliable, which improves the structural rationality of the tobacco recycling device.

[0045] For example, the second blowing mechanism 5 further includes a first positioning member 53, on which a second positioning member 54 is detachably mounted. The second positioning member 54 can be repositioned on the first positioning member 53 along the axial direction of the cigarette conveying wheel 1. The second air nozzle 52 is mounted on the second positioning member 54. This arrangement allows for adjustment of the distance between the second air nozzle 52 and the filter of the cigarette to be recycled, thereby accommodating cigarettes of different sizes and improving the structural rationality of the tobacco recycling device.

[0046] As another example, both the second drive component 42 and the third drive component 51 are cylinders or hydraulic cylinders to improve the reliability and economy of the second drive component 42 and the third drive component 51.

[0047] In some optional embodiments, the tobacco recycling device further includes a tobacco storage component 6, which has a tobacco storage chamber for storing cigarettes to be recycled. The lower end of the tobacco storage component 6 has an opening, and the cigarette conveying wheel 1 is located below the opening. The cigarettes to be recycled in the tobacco storage chamber can fall into the wheel groove 11 through the opening, thereby supplying the cigarette conveying wheel 1 with cigarettes to be recycled and improving the structural rationality of the tobacco recycling device.

[0048] In some optional embodiments, the first blowing mechanism 4 is located at one end of the cigarette conveying wheel 1 along its own axial direction, and the second blowing mechanism 5 is located at the other end of the cigarette conveying wheel 1 along its own axial direction, so that the first blowing mechanism 4 and the second blowing mechanism 5 are closer to the corresponding filter tip, which facilitates fixing and blowing operations and improves the structural rationality of the tobacco recycling device.

[0049] For example, an arc plate 7 is also installed at the lower end of the cigarette storage unit 6. The arc plate 7 is located on one side of the cigarette conveying wheel 1 and is spaced apart from the cigarette conveying wheel 1. The extension direction of the arc plate 7 is circumferential to the cigarette conveying wheel 1. A detection hole is opened on the arc plate 7, and the detection end of the color difference detection sensor 3 is directly opposite the detection hole. A first fixing hole and a second fixing hole are also installed on the arc plate 7. A first pin 41 can pass through the first fixing hole, and a second pin can pass through the second fixing hole. The arc plate 7 can prevent the cigarette from falling, and the arc plate 7 can block the cigarette when the first pin 41 and the second pin retract, so that the cigarette can fall off smoothly, improving the structural rationality of the tobacco recycling device.

[0050] In some optional embodiments, the tobacco recycling device further includes a numbering mechanism, which includes a metal marker and an origin sensor. The metal marker is disposed on the tobacco conveying wheel 1 and corresponds to a groove 11. The origin sensor is spaced apart on the side of the tobacco conveying wheel 1 and is coupled to the central controller. The origin sensor can sense the metal marker. After the origin sensor senses the metal marker, the central controller can set the number of the groove 11 corresponding to the metal marker to 1. After the tobacco conveying wheel 1 rotates by a preset angle W, the central controller can increment the number of the groove 11 behind the groove 11 corresponding to the metal marker by 1, where W = 360° / N, and N is the number of grooves 11.

[0051] Understandably, the numbering mechanism can perform mechanical zero-point marking. The cigarette conveying wheel 1 rotates until the origin sensor detects the metal marker. At this moment, the origin sensor outputs a rising edge signal. The central controller captures this instant, forcibly sets the current position to 0°, and simultaneously sets the current groove number to 1, completing the mechanical zero-point calibration. As the cigarette conveying wheel 1 rotates, the number of the groove 11 behind the metal marker is incremented by 1, thus numbering all the grooves 11. This facilitates the correspondence between the numbering and the filter orientation information, allowing the central controller to perform differentiated operations (controlling the first blowing mechanism 4 or the second blowing mechanism 5) on the cigarettes to be recycled in different numbered grooves 11 according to the filter orientation. In addition, the central controller can increment the number of the groove 11 behind the metal marker by 1 after each preset angle W rotation of the cigarette conveying wheel 1, where W = 360° / N, and N is the number of grooves 11, thus ensuring that adjacent grooves 11 are numbered every time the cigarette conveying wheel 1 rotates.

[0052] It is worth noting that, taking N=26 as an example, the cigarette conveying wheel 1 has 26 grooves 11 evenly distributed around its circumference. The angle between adjacent grooves 11 is fixed at 360° / 26≈13.846°. After calibrating the zero point through the origin sensor, the groove 11 corresponding to the zero point is defined as groove number 1. After the cigarette conveying wheel 1 rotates 13.846°, the number of the subsequent grooves 11 is incremented by 1. The groove number adopts a cyclic counting method: 1→2→3→……→26→1. Automatic reset to 1 is achieved through the remainder operation to ensure that the groove number always cycles within the range of 1 to 26.

[0053] It should also be noted that the metal marker has a certain width, and the origin sensor will remain conductive within a short arc length. However, the central controller only latches the position at the instant of the signal rising edge. The repeatability of the inductive proximity switch is about 0.01~0.2mm, which translates to an angular deviation of no more than 0.12°. The distance between adjacent wheel grooves 11 is 13.846°. This deviation is less than 1% of the groove distance and will not cause misjudgment of wheel groove 11. Moreover, this deviation is a fixed value and will not accumulate with operation.

[0054] For example, both the second drive unit 42 and the third drive unit 51 are equipped with two-position five-way solenoid valves. When energized, the movable end extends out of the fixed filter tip, and when de-energized, the spring returns to its original position, thus improving the structural rationality of the tobacco recycling device.

[0055] For example, the positive pressure air source is an air compressor, which is equipped with a two-position normally closed solenoid valve. When energized, it opens to blow out compressed air and when de-energized, it closes.

[0056] In some optional embodiments, the tobacco recycling device also includes a feeding detection sensor, which can detect whether there are tobacco sticks to be recycled in the wheel groove 11, thereby facilitating the monitoring of the situation in the wheel groove 11 and improving the structural rationality of the tobacco recycling device.

[0057] It is worth noting that the central controller, color difference detection sensor 3, origin sensor, material feeding detection sensor and solenoid valve are all powered by a unified 24V DC switching power supply, while the main power supply of the first drive unit 2 is directly supplied by the AC power grid.

[0058] On the other hand, this embodiment also proposes a recycling method, which uses the tobacco recycling device described above to improve the tobacco recycling rate and reduce the recycling breakage rate.

[0059] like Figure 3 As shown, the recycling method includes the following steps:

[0060] S1. Control the cigarette conveying wheel 1 to rotate by a preset angle, and number the wheel grooves 11 sequentially;

[0061] S2. Determine whether the target wheel groove 11 is located at the inspection station;

[0062] S3. If the target wheel groove 11 is located at the detection station, read the detection result of the color difference detection sensor 3 to obtain the filter orientation of the cigarette to be recycled, and match the filter orientation of the cigarette to be recycled with the number of the target wheel groove 11, and return to step S1. If the target wheel groove 11 is not located at the detection station, determine whether the target wheel groove 11 is located at the first blowing station.

[0063] S4. If the target groove 11 is located at the first blowing station, determine whether the filter of the cigarette to be recycled in the target groove 11 is facing the first direction. If yes, the first blowing mechanism 4 is activated. After the activation is completed, the number of the target groove 11 is cleared and the process returns to step S1. If no, the process returns directly to step S1. If the target groove 11 is not located at the first blowing station, determine whether the target groove 11 is located at the second blowing station. If yes, determine whether the filter of the cigarette to be recycled in the target groove 11 is facing the second direction. If the filter of the cigarette to be recycled in the target groove 11 is facing the second direction, the second blowing mechanism 5 is activated. After the activation is completed, the process returns to step S1. If the filter of the cigarette to be recycled in the target groove 11 is not facing the second direction, the process returns to step S1. The second direction is the opposite direction of the first direction.

[0064] Understandably, each time the cigarette conveying wheel 1 rotates by a preset angle W, the central controller numbers the wheel groove 11, ensuring that each wheel groove 11 is numbered. If any wheel groove 11 is selected as the target wheel groove 11, and the target wheel groove 11 is in the detection station, the color difference detection sensor 3 detects the filter orientation of the cigarette to be recycled in the target wheel groove 11 and associates this filter orientation information with the number of the target wheel groove 11. This facilitates quick lookup of the filter orientation information based on the number when the target wheel groove 1 is in the first or second blowing station. After detection, the system returns to step S1, causing the cigarette conveying wheel 1 to rotate again by the preset angle W to continue numbering and to detect the filter orientation of the cigarette to be recycled in the next wheel groove 11. If the target groove 11 is not located at the detection station, it is determined whether the target groove 11 is located at the first blowing station or the second blowing station. Then, the filter orientation of the cigarette to be recycled in the target groove 11 is determined. If it is in the first direction (one end of the cigarette conveying wheel 1 along the axis) and located at the first blowing station, the first blowing mechanism 4 is activated. If it is in the second direction (the other end of the cigarette conveying wheel 1 along the axis) and located at the second blowing station, the second blowing mechanism 5 is activated. In other cases, the cigarette conveying wheel 1 needs to continue rotating by a preset angle W to perform cyclic detection and blowing operations, thereby improving the tobacco recycling rate and reducing the recycling breakage rate. That is, the tobacco recycling method proposed in this embodiment can correspond the number of the groove 11 with the filter orientation information. When the target groove 11 is located at different stations, the filter orientation information can be quickly queried according to the number. Then, according to the filter orientation information and whether it is located at the first blowing station or the second blowing station, the first blowing mechanism 4 or the second blowing mechanism 5 is activated. The determination is relatively simple and smooth, ensuring the accuracy of blowing.

[0065] In some optional embodiments, before numbering the wheel grooves 11 sequentially in step S1, the method further includes: calibrating the cigarette conveying wheel 1 to zero to ensure the accuracy of the numbering.

[0066] It is worth mentioning that the zero-point calibration specifically includes: the cigarette conveyor wheel 1 rotates until the origin sensor senses the metal marker. At this time, the origin sensor outputs a rising edge signal.
