Description

Technical Field

[0001] This invention relates to the field of cigarette manufacturing technology, and in particular to a grooved belt cigarette lifting method and a grooved belt cigarette lifting device. Background Technology

[0002] Cigarette storage and conveying equipment is used to transport cigarettes produced by cigarette rolling machines to packaging machines, and has storage and buffering adjustment functions. Currently, this type of equipment (including YF17A, YF12, Various160, S90 / 140, COMFLEX-ML, COMFLEX-SL, etc.) mostly uses chain plate belts, mesh belts, flat belts, etc., with clamping (clamping) lifting on both sides, relying on the friction generated by the squeezing and relative movement of the cigarettes in the channel by the clamping belt to lift the cigarettes.

[0003] However, this type of cigarette lifting device has problems such as cigarettes falling and tilting, shrinking and deforming, empty ends, disordered cigarettes, and defective cigarettes during operation, which affect product quality. In addition, since the device needs to have enough cigarettes to be piled up and compressed in order to work properly, the cigarettes in the lifting channel cannot be automatically emptied, resulting in a lot of cigarette waste during the start-up, operation and closing of the equipment.

[0004] Therefore, there is an urgent need for a grooved belt cigarette lifting method and a grooved belt cigarette lifting device to solve the above-mentioned technical problems. Summary of the Invention

[0005] One object of the present invention is to provide a grooved belt cigarette lifting method that can lift cigarettes without negatively affecting the quality of the cigarettes or causing cigarette waste.

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

[0007] The grooved belt cigarette lifting method includes:

[0008] S1. The cigarette sticks are adsorbed one by one onto the groove synchronous belt at a low position, and multiple receiving grooves are formed along the length direction of the groove synchronous belt, and each receiving groove can accommodate one cigarette stick in a horizontal position.

[0009] S2. Rotate the grooved synchronous belt to transport the cigarette towards a higher position;

[0010] S3. When the cigarette reaches the high position, stop adsorbing the cigarette so that the cigarette can be detached from the receiving tank.

[0011] In some embodiments, in step S2, the cigarettes are conveyed one by one and continuously toward the high position, and in step S3, at least three cigarettes are grouped together, and when a group of cigarettes reaches the high position, the adsorption of the group of cigarettes is stopped.

[0012] Another objective of this invention is to provide a grooved belt cigarette lifting device that can lift cigarettes without negatively impacting their quality or causing any waste.

[0013] To achieve this objective, the present invention adopts the following technical solution:

[0014] A grooved belt cigarette lifting device is used to implement the above-described grooved belt cigarette lifting method, wherein the grooved belt cigarette lifting device includes:

[0015] A grooved synchronous belt, wherein multiple receiving grooves are arranged on the outer surface of the grooved synchronous belt, each receiving groove can accommodate a cigarette in a horizontal position, and each receiving groove is provided with an adsorption hole, the adsorption hole can adsorb and fix the cigarette in the receiving groove.

[0016] A drive wheel, wherein the drive wheel is rotatably positioned at a low position;

[0017] The driven wheel is rotatably positioned at a high position, and the grooved synchronous belt is wound around the driving wheel and the driven wheel and can circulate between the low and high positions;

[0018] A gas distribution component is fixedly disposed and extends between a low position and a high position, and a negative pressure cavity is formed between the gas distribution component and the inner surface of the groove synchronous belt. The adsorption hole can communicate with the negative pressure cavity to adsorb the cigarette during the movement from the low position to the high position, and is separated from the negative pressure cavity to release the cigarette during the movement from the high position to the low position.

[0019] In some embodiments, the air distribution component has a groove structure on the side facing the grooved synchronous belt, the length direction of the groove structure is arranged from the low position to the high position, the air distribution component and the inner surface of the grooved synchronous belt are slidably attached, and the air distribution component is connected to a negative pressure air interface, the negative pressure air interface and the groove structure are connected in communication.

[0020] In some embodiments, each of the receiving grooves is provided with at least two adsorption holes, and the at least two adsorption holes in each of the receiving grooves are arranged in a horizontal direction.

[0021] In some embodiments, the adsorption holes in at least three adjacent receiving grooves form a group, and each group of adsorption holes is arranged along a preset shape, and the contour of the high end of the groove structure corresponds to the preset shape, so that each group of adsorption holes is simultaneously separated from the negative pressure cavity.

[0022] In some embodiments, the preset shape includes any one of the following: a "V" shape, an "eight" shape, a "U" shape, and a "C" shape.

[0023] In some embodiments, the air distribution element has ridges for supporting the grooved timing belt. Each ridge includes two edge ridges and a central ridge located between the two edge ridges. The groove structure includes two venting slots, with one venting slot formed between the central ridge and each of the two edge ridges.

[0024] Each of the receiving slots is provided with two adsorption holes, one of which is located on one side of the central ridge and can communicate with a ventilation slot, and the other adsorption hole is located on the other side of the central ridge and can communicate with another ventilation slot.

[0025] In some embodiments, the central ridge is provided with at least three balancing air holes, and the two ventilation slots are connected through the balancing air holes.

[0026] In some embodiments, the drive wheel is connected to the cigarette machine via a transmission, and the drive wheel and the cigarette conveying drum of the cigarette machine are arranged to rotate synchronously and at the same speed.

[0027] The above technical solution has the following advantages or beneficial effects:

[0028] This grooved belt cigarette lifting device can transport cigarettes one by one from a low position to a high position. During the transport process, the cigarettes are adsorbed and fixed in the receiving groove, maintaining a stable horizontal posture and avoiding mutual compression and friction between cigarettes. This prevents problems such as cigarette sag, shrinkage, deformation, empty ends, disordered cigarettes, and defective cigarettes, ensuring product quality. It also allows for emptying of cigarettes, avoiding waste during equipment start-up, operation, and shutdown. The device can adjust parameters such as conveying distance and lifting height according to actual production needs, effectively improving the automation and flexibility of cigarette conveying and storage equipment. This technology can be widely applied to cigarette storage and conveying equipment such as YF12, Various160, COMFLEX-ML, and COMFLEX-SL. By simply changing the specifications and dimensions of the grooved synchronous belt, it can be used to lift and convey cigarettes of various specifications with diameters of 5.0–10.0 mm and lengths of 30–120 mm, demonstrating high potential for widespread application.

[0029] The grooved belt cigarette lifting method described above utilizes a grooved synchronous belt and negative pressure adsorption to transport cigarettes, ensuring that the cigarettes are positioned in a fixed and orderly manner during the lifting and transport process, without slippage or rolling. This guarantees no contact, friction, or squeezing between cigarettes, and no relative movement, rubbing, or squeezing between cigarettes and the synchronous belt. It eliminates damage such as squeezing and wear during cigarette lifting and solves problems such as cigarette skewing, wrinkles, deformation, empty ends, disordered cigarettes, and defective cigarettes. Furthermore, the cigarettes can be automatically emptied, eliminating the need to wait for a certain number of cigarettes to accumulate before starting the equipment. This also prevents significant cigarette waste during operation and shutdown, improving not only the stability and efficiency of cigarette transport but also the automation and flexibility of cigarette transport and storage equipment.

[0044] 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.

[0045] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," "fixed," and "abutting" 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.

[0046] 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.

[0047] In the description of this embodiment, the terms "upper," "lower," "right," and "left," 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.

[0048] like Figures 1 to 2 As shown, in related technologies, multiple cigarettes 100 are lifted by clamping them on both sides (clamping type). For example, taking the YF17A type cigarette storage and conveying equipment as an example, this equipment includes a lifting device, an overhead conveyor 109, a cigarette storage tank, and a cigarette output device 111. Upstream of this equipment, the cigarette machine unloads the cigarettes 100 into the lifting device via a cigarette conveying drum 101 and a cigarette unloading drum 102. The lifting device includes a cigarette conveying flat clamp 103 and a cigarette conveying chain belt 105. The cigarettes 100 can enter the cigarette conveying flat clamp 103 and then enter the channel defined by the cigarette conveying chain belt 105. The cigarette conveying chain belt 105 has an approximately "Z" shape, thus forming a connected low-level horizontal channel and a vertical channel 107. One end of the low-level horizontal channel is connected to the cigarette conveying flat clamp 103, and the other end is connected to the bottom end of the vertical channel 107 via an inlet bend 106. One end of the overhead conveyor 109 is connected to the top of the vertical channel 107 via the outlet bend 108, and the other end is connected to the cigarette storage tank and the cigarette output device 111. Cigarettes 100 are first piled and compressed to a certain density at the cigarette conveyor chain 105, then lifted and clamped by the vertical channel 107 into the overhead conveyor 109 and the cigarette output device 111, and subsequently into the packaging machine. If the packaging machine stops, excess cigarettes 100 will be temporarily stored in the cigarette storage tank 110. Optionally, the device also includes a sampling drum 104, which can pick up cigarettes 100 at the cigarette conveyor drum for convenient quality sampling and inspection.

[0049] like Figure 2As shown, the lifting device mainly includes a horizontal chain plate 1051, inlet upper and lower chain plates 1052, left and right chain plates 1053, and outlet upper and lower chain plates 1054. Under the action of the horizontal chain plate 1051, inlet upper and lower chain plates 1052, left and right chain plates 1053, and outlet upper and lower chain plates 1054, the cigarette 100 can move from a low position to a high position. When the cigarette 100 is between the left and right chain plates 1053, the cigarette 100 will be squeezed and move relative to the chain plates 1053. Specifically, a frictional force F is generated between the left and right chain plates 1053 and the outer layer of the cigarette 100, causing the outer layer of the cigarette 100 to roll upward with the chain plates. At the same time, a frictional force is also generated between the outer layer of the cigarette 100 and the inner layer of the cigarette 100, thereby driving the inner layer of the cigarette 100 to roll upward. When the resultant force of the upward friction is less than the weight G of the cigarette 100 itself in the channel, the cigarette 100 will sag or intermittently slide down, increasing the density of the cigarette 100 in the channel and thus increasing the friction between the cigarette 100 and the chain plate. When the resultant force of the friction is greater than the weight G of the cigarette 100 itself in the channel, the cigarette 100 will be lifted... This process repeats until the cigarette 100 reaches the exit bend 108 and enters the overhead conveyor 109. During this repeated process, the cigarette 100 is constantly rolled and squeezed. When the lit end of the cigarette 100 undergoes plastic deformation due to rolling and squeezing, a speed difference occurs between the lit end and the filter end, resulting in horizontal smoke and disordered smoke, causing dead angles and blockages at the inlet bend 106.

[0050] Furthermore, the continuous rolling and squeezing of cigarettes 100 can also result in a large number of wrinkled cigarettes, empty cigarettes, and other defective cigarettes 100. When the equipment starts up, it must wait for the cigarettes 100 to accumulate and reach a certain density at the conveyor chain 105 before it can be lifted. During the final stages of production, the cigarette machine stops supplying cigarettes 100, reducing the density of cigarettes 100 in the channel. This reduces the frictional force generated by squeezing, preventing the cigarettes 100 from being conveyed to the packaging machine. To clear the cigarettes 100, in actual production, manual lifting or stuffing elastic blocks between the chain plates is often used to remove them, resulting in waste and compromising safety.

[0051] To address the aforementioned problems, embodiments of the present invention provide a grooved belt cigarette lifting method and a grooved belt cigarette lifting device, which can fundamentally prevent the rolling and squeezing of the cigarette 100. The following is based on... Figures 3 to 9 This invention introduces the grooved belt cigarette lifting device and the grooved belt cigarette lifting method provided by the present invention.

[0052] like Figure 3As shown, in this embodiment, the grooved belt cigarette lifting device (hereinafter referred to as the device) can replace the above-mentioned lifting device and be installed in the cigarette storage and conveying equipment. The bottom end of the device can be connected to the cigarette conveying drum 101, and the top end can be connected to the overhead conveyor 109, thereby completing the lifting operation of the cigarette 100 from a low position to a high position.

[0053] Specifically, such as Figure 4 , Figure 5 As shown, the lifting device mainly includes a grooved synchronous belt 201, a driving wheel 202, a driven wheel 203, and a gas distribution component 204. The gas distribution component 204 is fixedly installed, the driving wheel 202 is positioned at a lower position, and the driven wheel 203 is positioned at a higher position, with both the driving wheel 202 and the driven wheel 203 connected to the gas distribution component 204. The grooved synchronous belt 201 is wound around the driving wheel 202 and the driven wheel 203 and can circulate between the lower and higher positions. Multiple receiving grooves are provided on the outer surface of the grooved synchronous belt 201, arranged along the length of the belt, and each groove can accommodate one cigarette 100 in a horizontally confined position. Each groove also has an adsorption hole 2011, which adsorbs and fixes the cigarette 100 within the groove. The pitch of the receiving groove is p, which is equal to the groove pitch of the cigarette conveying drum 101. Preferably, the length of the receiving groove and the width of the groove synchronous belt 201 are set according to the length of the cigarette 100, so that both ends of the cigarette 100 can be received and fixed to avoid collision damage.

[0054] The air distribution component 204 extends between the low and high positions and is located inside the grooved synchronous belt 201. The air distribution component 204 and the inner surface of the grooved synchronous belt 201 are in contact, defining a negative pressure cavity 2040. During the rotation of the grooved synchronous belt 201, when the adsorption hole 2011 reaches the low position and moves from the low position to the high position, the adsorption hole 2011 can communicate with the negative pressure cavity 2040, thereby adsorbing the cigarette 100 located in the receiving groove. When the adsorption hole 2011 reaches the high position and moves from the high position to the low position, the adsorption hole 2011 can separate from the negative pressure cavity 2040, thereby releasing the cigarette 100 and conserving negative pressure resources.

[0055] This device can transport cigarettes 100 one by one from a low position to a high position. During the transport process, each cigarette 100 is adsorbed and fixed in the receiving tank, maintaining a stable horizontal posture and avoiding mutual squeezing and friction between cigarettes 100. This prevents problems such as cigarettes 100 falling, tilting, shrinking, deformation, empty ends, disordered cigarettes, and defective cigarettes, ensuring product quality. It also allows for the emptying of cigarettes 100, avoiding waste during equipment start-up, operation, and shutdown. The device can adjust parameters such as conveying distance and lifting height according to actual production needs, effectively improving the automation and flexibility of cigarette 100 conveying and storage equipment. This technology can be widely applied to cigarette storage and conveying equipment such as YF12, Various160, COMFLEX-ML, and COMFLEX-SL. By simply changing the specifications and dimensions of the grooved synchronous belt 201, it can be used for lifting and conveying cigarettes of various specifications with diameters of 5.0 to 10.0 mm and lengths of 30 to 120 mm, and has high value for promotion and application.

[0056] Specifically, such as Figure 5 As shown, in this embodiment, the gas distribution component 204 includes a low-position portion 2041, a high-position portion 2042, and a middle portion 2043. The low-position portion 2041 is located at a low position, and the driving wheel 202 is rotatably connected to the low-position portion 2041. The high-position portion 2042 is located at a high position, and the driven wheel 203 is limited and connected to the high-position portion 2042. The middle portion 2043 is connected between the low-position portion 2041 and the high-position portion 2042. It should be noted that in this invention, the low-position and high-position are not limited to the bottom and top ends of the gas distribution component 204, but can also be positions close to the bottom and top ends, as long as the height of the cigarette 100 can be increased.

[0057] Continue to refer to Figure 5 As shown, each receiving groove is provided with at least two adsorption holes 2011, which are arranged horizontally to achieve multi-point adsorption of the cigarette 100, resulting in better adsorption and fixation and improving the stability of the cigarette 100 during the lifting process. The gas distribution component 204 has a groove structure on the side facing the grooved synchronous belt 201, and the length direction of the groove structure is arranged from the low position to the high position. The gas distribution component 204 and the inner surface of the grooved synchronous belt 201 slide against each other, so that the groove structure and the inner surface of the grooved synchronous belt 201 can define and form the aforementioned negative pressure cavity 2040. The gas distribution component 204 is connected to a negative pressure gas interface 205, which is connected to the groove structure. The negative pressure gas inlet 205 can communicate with the inside of the groove structure. The gas inside the groove structure can be extracted through the negative pressure gas inlet 205, thereby forming a negative pressure in the negative pressure cavity 2040, and then adsorbing and fixing the cigarette 100 through the adsorption hole 2011.

[0058] Furthermore, such as Figure 6 , Figure 7 As shown, the device also includes a frame 301, a rotating shaft 303, and a support shaft 306. The frame 301 is fixedly mounted, the rotating shaft 303 is rotatably connected to the frame 301 at a lower position, and the support shaft 306 is fixedly connected to the frame 301 at a higher position. Both the lower position 2041 and the higher position 2042 have through holes. The rotating shaft 303 passes through the through hole in the lower position 2041, and the support shaft 306 passes through the through hole in the higher position 2042. Bearings are connected between the rotating shaft 303 and the lower position 2041, and between the support shaft 306 and the driven wheel 203, so that the rotating shaft 303 and the support shaft 306 can fix the air distribution component 204 and prevent the air distribution component 204 from rotating.

[0059] One end of the rotating shaft 303 is connected to a drive gear 304, which in turn connects to a servo motor and other driving components to provide power for the rotation of the grooved synchronous belt 201. The drive pulley 202 includes a first drive pulley 2021 and a second drive pulley 2022. The first drive pulley 2021 is located on one side of the air distribution component 204, and the second drive pulley 2022 is located on the other side. The first drive pulley 2021 and the second drive pulley 2022 are fixedly connected to the rotating shaft 303 via keys and nuts, and can respectively connect to one edge of the grooved synchronous belt 201 for transmission. This ensures that the grooved synchronous belt 201 is subjected to balanced forces, resulting in superior conveying effect and stability, and ensuring stable transmission of cigarettes 100 between the cigarette conveying drum 101 and the grooved synchronous belt 201. Preferably, a bracket 302 is connected to the end of the rotating shaft 303 away from the gear. The bracket 302, in conjunction with the frame 301, supports and fixes the rotating shaft 303 and the air distribution component 204. The bracket 302 and the rotating shaft 303 are rotatably connected by bearings. A first round nut 305 is provided between the bearing connected to the frame 301 and the first drive pulley 2021, and between the bearing connected to the bracket 302 and the second drive pulley 2022, along the axial direction of the rotating shaft 303, thereby limiting the drive pulley 202 and the air distribution component 204 along the axial direction of the rotating shaft 303.

[0060] Preferably, the drive gear 304 is connected to the cigarette machine drive (e.g., the cigarette conveying drum 101) to introduce power from the cigarette machine and achieve synchronous operation. Of course, when using a servo motor to drive the drive gear 304, in order to ensure that the grooved synchronous belt 201 rotates synchronously with the cigarette conveying drum 101 when it is in a low position and has the same linear speed, the drive wheel 202 and the cigarette conveying drum 101 can be ensured to operate synchronously and at the same speed through speed regulation or the control system of the servo motor.

[0061] Similarly, one end of the support shaft 306 is fixedly connected to the frame 301 to support structures such as the air distribution component 204 and the grooved synchronous belt 201. The driven pulley 203 includes a first driven pulley 2031 and a second driven pulley 2032. The first driven pulley 2031 is located on one side of the air distribution component 204, and the second driven pulley 2032 is located on the other side of the air distribution component 204. The support shaft 306 passes directly through the through hole of the high position 2042, and bearings are connected between the support shaft 306 and the first driven pulley 2031 and the second driven pulley 2032, thereby decoupling the rotation of the first driven pulley 2031 and the second driven pulley 2032 from the support shaft 306. The rotating shaft 303 and the support shaft 306 are rotatably connected to the air distribution component 204 and the driven pulley 203 via bearings, respectively. This simple structure not only secures the air distribution component 204 and the grooved synchronous belt 201 but also drives the grooved synchronous belt 201 to rotate without transmitting the rotational motion to the air distribution component 204, ensuring stable operation and improving the device's efficiency. Optionally, a second round nut 307 is fitted onto the support shaft 306, which can axially limit the movement of the second driven pulley 2032 and the first driven pulley 2031 along the support shaft 306.

[0062] like Figures 5 to 7 As shown, in this embodiment, the air distribution component 204 has ridges for supporting the grooved synchronous belt 201. The ridges include two edge ridges 2044 and a central ridge 2045 located between the two edge ridges 2044. The aforementioned groove structure includes two venting grooves 20401, with a venting groove 20401 formed between the central ridge 2045 and each of the two edge ridges 2044. The aforementioned negative pressure air inlet 205 communicates with the two venting grooves 20401, thereby creating negative pressure within the venting grooves 20401.

[0063] Of the two adsorption holes 2011 in each receiving tank, one adsorption hole 2011 is located on one side of the central ridge 2045 and can communicate with a ventilation slot 20401, while the other adsorption hole 2011 is located on the other side of the central ridge 2045 and can communicate with another ventilation slot 20401, so that both adsorption holes 2011 in each receiving tank can communicate with a corresponding ventilation slot 20401.

[0064] Optionally, the central ridge 2045 is provided with at least three balancing air holes 20451, and the two ventilation slots 20401 are connected through the balancing air holes 20451. This avoids excessive difference in negative pressure within the two ventilation slots 20401, thus helping the cigarette 100 maintain a horizontal posture during high-speed movement and preventing one end of the cigarette 100 from detaching from the receiving slot when the grooved synchronous belt 201 rotates at high speed. The central ridge 2045 and the edge ridges 2044 provide better support, preventing the grooved synchronous belt 201 from concave and deforming under strong negative pressure. This allows for the use of strong negative pressure to adsorb and fix the cigarette 100 in the lifting device, thereby increasing the rotational speed of the grooved synchronous belt 201 and ensuring the lifting efficiency of the cigarette 100. Preferably, the air distribution component 204, the central ridge 2045, and the edge ridge 2044 are all made of materials such as polytetrafluoroethylene, bakelite, or metal with a surface anti-friction treatment, in order to reduce the wear of the grooved synchronous belt 201 and extend its service life.

[0065] Furthermore, such as Figure 8 , Figure 9 As shown, the adsorption holes 2011 in each of at least three adjacent receiving slots form a group. Each group of adsorption holes 2011 is arranged along a preset shape, and the contour of the higher end of the groove structure corresponds to the preset shape, so that each group of adsorption holes 2011 is simultaneously separated from the negative pressure chamber 2040. Exemplarily, in this embodiment, five adjacent receiving slots form a group, allowing five cigarettes 100 to be released simultaneously each time, achieving rapid stacking and reducing the likelihood of disordered cigarettes. Simultaneous release also reduces the impact and damage to the cigarettes 100, minimizing the occurrence of cigarette tip burn, thereby further improving efficiency.

[0066] Optionally, in this embodiment, the preset shape is a "V" shape, and the outer contours of the two ventilation slots 20401 are also set along the shape of a "V", so that the adsorption holes 2011 of the five receiving slots can be simultaneously isolated from the negative pressure chamber 2040. In some other embodiments, the preset shape can also be an "eight" shape, a "U" shape, a "C" shape, etc. Therefore, the preset shape is not specifically limited in this invention, as long as it can achieve the group release of cigarettes 100.

[0067] It is understandable that, in addition to its shape, the position of the groove structure at the lower part 2041 and the higher part 2042 also affects the adsorption and release of the cigarette 100. Therefore, according to the preset adsorption and release positions, the two ends of the groove structure need to be extended to the corresponding preset positions at the lower part 2041 and the higher part 2042, so that the cigarette 100 is adsorbed when it enters the receiving groove at the adsorption position and is released when it reaches the release position.

[0068] This invention also discloses a method for lifting a grooved belt cigarette, implemented using the aforementioned grooved belt cigarette lifting device. The method specifically includes:

[0069] S1. The cigarette sticks 100 are adsorbed one by one onto the groove synchronous belt 201 at a low position. Multiple receiving grooves are formed along the length direction on the groove synchronous belt 201, and each receiving groove can accommodate one cigarette stick 100 in a horizontal position.

[0070] Specifically, in step S1, by connecting the negative pressure supply device to the gas distribution component 204, negative pressure is provided to the adsorption holes 2011 in the groove synchronous belt 201, thereby achieving the adsorption of the cigarette 100 and stably and correspondingly accommodating the cigarette 100 in the accommodating groove.

[0071] S2. Rotate the grooved synchronous belt 201 to transport the cigarette stick 100 towards the high position.

[0072] Specifically, in step S2, the drive gear 304 is connected to the cigarette machine via a drive shaft 303, a drive wheel 202, and a grooved synchronous belt 201. This allows the grooved synchronous belt 201 to rotate synchronously with the cigarette conveying drum 101 of the cigarette machine. This enables the transfer of the cigarette 100 from the cigarette conveying drum 101 to the grooved synchronous belt 201, and also allows the cigarette 100 to be conveyed towards a higher position. Of course, in some other embodiments, other conveying components besides the drum can be used to convey the cigarette 100. Therefore, as long as the cigarettes 100 can be fed into the receiving slot one-to-one, they fall within the scope of protection of this invention.

[0073] S3. When the cigarette 100 reaches the high position, stop adsorbing the cigarette 100 so that the cigarette 100 can be removed from the receiving tank.

[0074] Specifically, in step S3, by rationally designing the shape and position of the groove structure on the gas distribution component 204 according to the preset release position, it is possible to ensure that when the cigarette 100 moves to the release position, the adsorption hole 2011 loses its negative pressure suction, thereby releasing the cigarette 100 under the action of inertia. Of course, in some other embodiments, a blowing chamber can also be provided on the gas distribution component 204 so that the adsorption hole 2011 has blowing pressure after losing its negative pressure suction, thereby blowing the cigarette 100 out for release. This also falls within the scope of protection of this invention.

[0075] The grooved belt cigarette lifting method described above utilizes a grooved synchronous belt 201 and negative pressure adsorption to transport cigarettes 100. This ensures that the cigarettes 100 are positioned in a fixed and orderly manner during the lifting and transport process, without slippage or rolling. This guarantees no contact, friction, or compression between cigarettes 100, and no relative movement, rubbing, or compression between the cigarettes 100 and the synchronous belt. It eliminates damage such as compression and wear during the lifting process and solves problems such as cigarette 100 skewing, wrinkles, deformation, empty ends, disordered cigarettes, and defective cigarettes. Furthermore, the cigarettes 100 can be automatically emptied. The equipment does not require waiting for cigarettes to accumulate to a certain quantity before starting; it can operate synchronously with the cigarette rolling machine. During operation and termination, it does not cause significant waste of cigarettes 100. This not only improves the stability and efficiency of cigarette 100 transport but also effectively enhances the automation and flexibility of the cigarette 100 transport and storage equipment.

[0076] Preferably, in step S2, the cigarettes 100 are conveyed one by one and continuously toward the high position, and in step S3, at least three cigarettes 100 are grouped together, and when a group of cigarettes 100 reaches the high position, the adsorption of the group of cigarettes 100 is stopped.

[0077] Specifically, "one by one and continuously" means placing each cigarette 100 into its corresponding receiving slot and continuously conveying them by rotating the grooved synchronous belt 201, thereby achieving efficient lifting. Simultaneously, the design of the groove structure and the arrangement of the adsorption holes 2011 ensures that their outlines or arrangements conform to a preset shape, allowing a group of cigarettes 100 to be released simultaneously when reaching a high position, achieving rapid stacking and minimizing the risk of misplaced cigarettes. Furthermore, simultaneous release reduces the impact and damage to the cigarettes 100, minimizing the occurrence of cigarette tip burn, thus further improving efficiency.
