Description

Technical Field

[0001] This application relates to the field of cigarette pack conveying technology, and in particular to an automatic cigarette pack replenishment and conveying device for high-speed packaging equipment. Background Technology

[0002] In cigarette production, to reduce costs, some rejected or traceable cigarette packs need to be screened and repackaged. However, because high-speed packaging equipment such as ZB416, GDX6, and GDH1000 have elevated cigarette pack channels, often exceeding 2 meters in height, adding these packs is difficult. Furthermore, in related technologies, cigarette packs are primarily placed manually in the channel, a cumbersome process that consumes significant manpower and time, resulting in low efficiency. Summary of the Invention

[0003] The purpose of this application is to provide an automatic cigarette pack replenishment and conveying device for high-speed packaging equipment, which solves the problem of difficulty in manually replenishing cigarette packs in high-speed packaging equipment in related technologies.

[0004] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0005] This application provides a high-speed packaging equipment automatic cigarette pack replenishment and conveying device, comprising:

[0006] frame;

[0007] A cigarette delivery mechanism, disposed within the frame, is used to place and deliver cigarette packs;

[0008] A conveying mechanism is disposed on the frame and located on the output side of the cigarette delivery mechanism, and is adapted to receive the cigarette packs conveyed by the cigarette delivery mechanism;

[0009] A lifting mechanism is provided on the frame and located on the output side of the conveying mechanism. The lifting mechanism is used to receive the cigarette pack transferred by the conveying mechanism and lift the cigarette pack to the target height position.

[0010] A toggle mechanism, disposed in the frame, is used to transfer the cigarette pack located at the target height position in the lifting mechanism to the conveyor belt of the high-speed packaging equipment.

[0011] This solution utilizes a combination of a feeding mechanism and a conveying mechanism to transport cigarette packs at a lower position. The conveying and lifting mechanisms work together to elevate the cigarette packs to the target height, meeting the height requirements of the cigarette pack passageway in high-speed packaging equipment. A shifting mechanism then transfers the cigarette packs at the target height from the lifting mechanism to the conveyor belt of the high-speed packaging equipment, achieving automated pack replenishment. This effectively reduces labor costs, avoids errors caused by manual operation, and ensures that the cigarette packs do not shift, collide, or get damaged during conveying, lifting, and shifting, thus guaranteeing the appearance quality of the cigarette packs. This solution, through the coordinated operation of various mechanisms, achieves continuous cigarette pack transport and is suitable for large-scale tobacco production scenarios.

[0012] Optionally, the conveying mechanism includes:

[0013] Multiple placement plates are arranged parallel to each other at equal intervals on the frame;

[0014] A first transmission assembly is disposed between each pair of adjacent placement plates. The first transmission assembly includes: two first transmission wheels rotatably disposed on the frame, a first transmission belt wound around the two first transmission wheels, and a first driving member for driving the first transmission belt to rotate around the first transmission wheels. The top surface of the first transmission belt is lower than the top surface of the placement plate, and a toggle block is disposed on the first transmission belt for toggle the cigarette packs on the two adjacent placement plates located on both sides thereon.

[0015] In this design, the conveying mechanism includes multiple placement plates and a first transmission assembly disposed between each pair of adjacent placement plates. In use, the cigarette feeding assembly transports cigarette packs to the two adjacent placement plates, and a moving block located between the two placement plates pushes the cigarette packs to move on the two placement plates. It should be noted that each moving block can push multiple cigarette packs in the same column to move simultaneously, and multiple moving blocks synchronously push the same number of cigarette packs to move.

[0016] Optionally, the lifting mechanism includes: a plurality of second transmission components arranged in parallel at equal intervals, each of the plurality of second transmission components corresponding one-to-one with a plurality of placement plates; each of the second transmission components includes: two second transmission wheels rotatably disposed on the frame, a second transmission belt wound around the two second transmission wheels, and a second driving member for driving the second transmission belt to rotate around the second transmission wheels; wherein, a lifting plate is disposed on the second transmission belt, and the lifting plates on two adjacent second transmission belts are correspondingly disposed, and the lifting plate is used to receive the cigarette pack located at the end of the placement plate moved by the actuating block.

[0017] In this design, the lifting mechanism includes multiple equidistant parallel second transmission components, each corresponding one-to-one with a plurality of placement plates. This means that the lifting plate can receive cigarette packs on the placement plates. By rotating the second transmission belt, the top surface of the lifting plate can be rotated to be on the same plane as the top surface of the placement plate. This allows the cigarette packs to move from the end of the placement plate in the cigarette pack movement direction to the lifting plate. Furthermore, to ensure smooth movement of the cigarette packs to the lifting plate, in some embodiments, the end of the placement plate protrudes between two adjacent lifting plates, thereby achieving a smooth transition of the cigarette packs.

[0018] During operation, when the lifting plate rotates to be parallel with the placement plate, the second drive component stops operating. Simultaneously, the first transmission component activates, and the actuating block pushes the tobacco packs, causing at least one layer of tobacco packs perpendicular to the pushing direction to be pushed onto the lifting plate. At this point, the first transmission component stops operating, and the second drive component restarts to lift the tobacco packs. This process is repeated until all tobacco packs in the actuating block's operating direction have been pushed. The actuating block can then disengage from the gap between two adjacent second transmission components and rotate back to its initial position for the next round of tobacco pack pushing. In some embodiments, multiple actuating blocks can be provided on each first transmission belt. After one actuating block completes its pushing operation, the next actuating block can immediately begin pushing tobacco packs.

[0019] Optionally, the actuating mechanism includes:

[0020] The third transmission assembly is disposed above the target height position. The third transmission assembly includes: two third transmission wheels rotatably disposed on the frame, a third transmission belt wound around the two third transmission wheels, and a third driving member for driving the third transmission belt to rotate around the third transmission wheels.

[0021] The actuating component includes a base plate disposed on the third transmission belt. A first clamping piece and a second clamping piece are respectively disposed on both sides of the base plate. The first clamping piece and the second clamping piece together define a clamping groove to be suitable for clamping the cigarette pack located at the target height position. A guiding wing is provided on the side of the first clamping piece away from the base plate, and the end of the guiding wing gradually deflects toward the side away from the second clamping piece.

[0022] When the actuating member actuates the cigarette pack located at the target height, the first clamping piece is adapted to move the cigarette pack toward the conveyor belt, and the actuating wing is adapted to be the first to contact the cigarette pack.

[0023] This solution uses a third transmission assembly to drive a cyclical movement of an actuating component, thereby moving cigarette packs at the target height onto the conveyor belt. The actuating component has a U-shaped structure, with first and second clamping plates on either side to hold the cigarette pack. To ensure the actuating component smoothly guides the cigarette pack into the clamping slot as the third transmission belt rotates, a guiding wing is provided on the side of the first clamping plate facing away from the base plate. The end of the guiding wing gradually deflects away from the second clamping plate. During the movement of the actuating component, the guiding wing contacts the cigarette pack first, facilitating its movement into the clamping slot. The cigarette pack in the clamping slot is then conveyed onto the transmission belt as the actuating component moves. Once the cigarette pack is on the conveyor belt, the third drive unit stops operating; after the conveyor belt has completely removed the cigarette packs from the clamping slot, the third drive unit restarts, repeating the actuation process for the next target height. It should be noted that in this design, the length of the actuating component corresponds to the number of cigarette packs, thus enabling it to clamp and actuate all the cigarette packs located on the lifting plate.

[0024] Optionally, the smoke delivery mechanism includes:

[0025] A cigarette pack rack includes a back plate and a protective plate. The protective plate is disposed on one side of the back plate relative to the conveying mechanism. The back plate and the protective plate together define a cigarette storage compartment to facilitate stacking of cigarette packs. The back plate is vertically provided with several layers of cigarette pushers, and the several layers of cigarette pushers correspond one-to-one with the stacked layers of cigarette packs.

[0026] A lifting assembly is disposed on the frame and located on the bottom side of the cigarette pack rack, for driving the cigarette pack rack to move up and down;

[0027] A cigarette pusher assembly is disposed on the frame and located on the side of the cigarette pack rack opposite to the conveying mechanism, and is used to push cigarette packs in the cigarette pack rack to the conveying mechanism through the cigarette pusher port.

[0028] Optionally, the lifting assembly includes:

[0029] A fixing frame, wherein the fixing frame is disposed on the frame;

[0030] A support frame is slidably connected to the fixed frame, and a transmission wheel is rotatably mounted on the support frame;

[0031] A lifting frame, which is slidably connected to the support frame on the side opposite to the fixed frame, and has an abutment plate on its top;

[0032] The first cylinder is disposed on the frame, and the output end of the first cylinder is connected to the support frame;

[0033] A lifting belt is fitted onto the two drive wheels and located between the fixing clamp and the lifting frame. The fixing frame and the lifting frame are respectively connected to the two sides of the lifting belt located on the drive wheels.

[0034] During operation, the first cylinder is activated, causing the support frame to move upward. Since the lifting belt is connected to the fixed frame, as the support frame moves upward, the lifting belt rotates around the drive wheel, thereby causing the lifting frame connected to the other side of the lifting belt to move upward. In this structure, the upward movement distance of the lifting frame includes the distance the support frame moves relative to the fixed frame, and the distance it moves relative to the support frame through the rotation of the lifting belt. This structure shortens the stroke of the first cylinder, which helps to reduce the longitudinal dimension of the entire device.

[0035] Optionally, the smoke-pushing assembly includes:

[0036] A linear module, wherein the linear module is disposed on the frame;

[0037] The bracket is connected to the slide of the linear module.

[0038] The cigarette pusher includes a push rod, one end of which is connected to the bracket and the other end is connected to a push plate. The push plate slides through the cigarette pusher opening and is used to push out the cigarette pack in the cigarette storage chamber.

[0039] In this design, tobacco packs are stacked in layers within the tobacco storage chamber, with each layer having a corresponding pusher. The pusher assembly propells the entire layer of tobacco packs to the conveyor mechanism via these pushers. A coordinated lifting assembly drives the tobacco pack rack to move up and down, enabling the pusher assembly to push the tobacco packs layer by layer.

[0040] Specifically, after the tobacco packs are stacked in layers in the tobacco storage bin, a lifting assembly raises them to the position corresponding to the topmost tobacco pusher and the pusher plate. At this point, the lifting operation stops; simultaneously, a linear module drives a push rod to move, and the pusher plate passes through the topmost tobacco pusher to push the topmost tobacco pack to the conveying mechanism. After the topmost tobacco pack is pushed, the linear module drives the push rod to reset, and the lifting assembly operates again to raise the next layer's tobacco pusher to the position corresponding to the pusher plate, repeating the above pushing steps to achieve the layer-by-layer pushing of tobacco packs.

[0041] Optionally, the cigarette delivery mechanism further includes: two fourth transmission components disposed on the frame and symmetrically disposed on both sides of the lifting assembly. Each fourth transmission component includes: two fourth transmission wheels rotatably disposed on the frame, a fourth transmission belt wound around the two fourth transmission wheels, and a fourth driving member for driving the fourth transmission belt to rotate around the fourth transmission wheels. The fourth transmission component is used to move the cigarette pack rack to directly above the lifting assembly.

[0042] When there are many cigarette packs, and the storage compartment of a single cigarette pack rack cannot hold them all, the operator needs to place the next stack of cigarette pack racks onto the lifting assembly after pushing all the cigarette packs in one rack. This process is quite cumbersome. In this solution, the cigarette feeding mechanism also includes a fourth transmission assembly, which is used to store the cigarette pack racks and push them to the lifting assembly. In use, the operator can place multiple full cigarette pack racks onto the fourth transmission belt. After pushing all the cigarette packs in the current rack, the rack can be removed, and the lifting assembly can be reset. At this time, the fourth drive unit is activated to move the next cigarette pack rack to the top of the lifting assembly, thus changing the cigarette pack rack.

[0043] Optionally, the smoke delivery mechanism further includes a recovery component, which includes a pull-out component and a conveying component;

[0044] The pull-out component includes: a second cylinder, which is disposed on the frame and has the same output direction as the linear module; a support rod is provided at the output end of the second cylinder, and pull plates are respectively provided at both ends of the support rod, with a hook head at the end of the pull plate away from the support rod;

[0045] The conveying component includes: two fifth transmission wheels rotatably mounted on the frame, a fifth transmission belt wound around the fifth transmission wheels, and a fifth driving component for driving the fifth transmission belt to rotate around the fifth transmission wheels, wherein the top surface of the fifth transmission belt is flush with the top surface of the pull plate.

[0046] This solution utilizes a recycling component to unload the cigarette pack racks after they have been pushed out of the lifting assembly. Specifically, a pull-out component is used to pull the cigarette pack racks out from the top of the lifting assembly. After the pushing assembly pushes the last layer of cigarette packs out of the rack, the second cylinder drives the support rod to move the pull plate towards the cigarette pack rack, until it is below the rack; at this time, the lifting assembly is positioned between the pull plates. As the lifting assembly descends, the cigarette pack racks fall onto the pull plates; then, the second cylinder drives the pull plate to reset, and under the action of the hook head, the cigarette pack racks move with the pull plate to above the conveyor. Multiple cigarette pack racks can be stored sequentially via the conveyor, enabling the recycling of the cigarette pack racks.

[0047] Optionally, a controller may also be included, which is used to control the operating status of the smoke delivery mechanism, the conveying mechanism, the lifting mechanism, and the actuating mechanism.

[0048] Optionally, the frame is provided with two parallel guide rails, which are arranged parallel to the fourth transmission belt, and the sides of the cigarette pack frame are respectively provided with guide rail grooves that fit with the two guide rails.

[0049] The guide rail groove and guide rail are used to prevent the cigarette pack rack from shifting during transportation.

[0050] Optionally, the frame is provided with a baffle, which is located above the fourth transmission component and parallel to the cigarette pack frame. When the cigarette pack frame moves to contact the baffle, the lifting component is located directly below the cigarette pack frame.

[0051] The baffle plate allows the cigarette pack rack to be moved precisely above the lifting assembly, thus ensuring the stability of the cigarette pack rack during the lifting process.

[0052] Optionally, the top surface of the baffle is aligned with the bottom surface of the placement plate.

[0053] During the lifting process, the space formed by the baffle and the cigarette pack rack can prevent the cigarette packs from scattering.

[0054] Compared with existing technologies, the beneficial effects achieved by this application are as follows: This application, through the cooperation of a cigarette feeding mechanism and a conveying mechanism, enables the transport of cigarette packs at a lower position. The cooperation of the conveying mechanism and the lifting mechanism allows the cigarette packs to be lifted to the target height, thereby meeting the height requirements of the cigarette pack channel in high-speed packaging equipment. The shifting mechanism transfers the cigarette packs at the target height from the lifting mechanism to the conveyor belt of the high-speed packaging equipment, achieving automated pack replenishment, effectively reducing labor costs, avoiding errors caused by manual operation, and ensuring that the cigarette packs do not shift, collide, or get damaged during conveying, lifting, and shifting, thus guaranteeing the appearance quality of the cigarette packs. This application, through the coordinated operation of various mechanisms, achieves continuous transport of cigarette packs and is suitable for large-scale tobacco production scenarios.

Detailed Implementation

[0070] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure / application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

[0071] Example 1

[0072] This embodiment describes an automatic cigarette pack replenishment and conveying device for high-speed packaging equipment, referencing... Figure 1 and Figure 2 This embodiment of an automatic cigarette pack replenishment and conveying device for high-speed packaging equipment includes a frame 6. A cigarette feeding mechanism 1, a conveying mechanism 2, a lifting mechanism 3, and a shifting mechanism 5 are arranged on the frame 6. The cigarette feeding mechanism 1 is used to convey cigarette packs. The conveying mechanism 2 is located on the output side of the cigarette feeding mechanism 1 and can receive the cigarette packs conveyed by the cigarette feeding mechanism 1 and further convey them to the lifting mechanism 3. The lifting mechanism 3 is located on the output side of the conveying mechanism 2 and can receive the cigarette packs conveyed by the conveying mechanism 2 and lift the received cigarette packs to a target height position. The target height position is not lower than the height of the conveyor belt 4 of the high-speed packaging equipment. The shifting mechanism 5 can move the cigarette packs located at the target height position onto the conveyor belt 4.

[0073] In operation, cigarette packs are conveyed from the cigarette feeding mechanism 1 to the conveying mechanism 2; then, the conveying mechanism 2 conveys the cigarette packs to the lifting mechanism 3; the lifting mechanism 3 lifts the cigarette packs to the target height, and then the actuating mechanism 5 moves the cigarette packs onto the conveyor belt 4; finally, the conveyor belt 4 transports the cigarette packs to the cigarette pack channel of the high-speed packaging equipment. This embodiment, through the cooperation of the cigarette feeding mechanism 1 and the conveying mechanism 2, enables the conveying of cigarette packs at a lower position. The cooperation of the conveying mechanism 2 and the lifting mechanism 3 lifts the cigarette packs to the target height, thus meeting the height requirements of the cigarette pack channel of the high-speed packaging equipment. The actuating mechanism 5 moves the cigarette packs at the target height from the lifting mechanism 3 onto the conveyor belt 4, and the conveyor belt 4 transports the cigarette packs to the elevated cigarette pack channel, achieving automated pack replenishment, effectively reducing labor costs, avoiding errors caused by manual operation, and ensuring that the cigarette packs do not shift, collide, or get damaged during conveying, lifting, and actuating, thus guaranteeing the appearance quality of the cigarette packs. This application, through the coordinated operation of various mechanisms, achieves continuous conveying of cigarette packs and is suitable for large-scale tobacco production scenarios.

[0074] Example 2

[0075] Based on the same inventive concept as Embodiment 1, refer to Figure 3In this embodiment, the conveying mechanism 2 includes a plurality of placement plates 21, which are equidistantly and parallelly arranged on the frame 6. A first transmission assembly 22 is provided between each pair of adjacent placement plates 21. The first transmission assembly 22 includes two first transmission wheels 221 rotatably disposed on the frame 6, a first transmission belt 222 wound around the two first transmission wheels 221, and a first driving member 224 for driving the first transmission belt 222 to rotate around the first transmission wheels 221. The top surface of the first transmission belt 222 is lower than the top surface of the placement plate 21, and a toggle block 223 is provided on the first transmission belt 222 for toggle the cigarette packs on the two adjacent placement plates 21 located on both sides of it.

[0076] In use, the cigarette delivery assembly conveys cigarette packs to two adjacent placement plates 21. A moving block 223 located between the two placement plates 21 then moves the cigarette packs between them. It is important to note that each moving block 223 can move multiple cigarette packs in the same column simultaneously, and multiple moving blocks 223 synchronously move the same number of cigarette packs. Here, "same column" refers to cigarette packs placed side-by-side in the direction of movement.

[0077] Further, refer to Figure 4 and Figure 5 In this embodiment, the lifting mechanism 3 includes a plurality of second transmission components 31 arranged equidistantly and parallel to each other, with each of the second transmission components 31 corresponding to a plurality of placement plates 21. This means that the lifting plate 313 can receive cigarette packs on the placement plate 21. Each second transmission component 31 includes two second transmission wheels 311 rotatably mounted on the frame 6, a second transmission belt 312 wound around the two second transmission wheels 311, and a second driving member 314 for driving the second transmission belt 312 to rotate around the second transmission wheels 311. The second transmission belt 312 is provided with a lifting plate 313, and the lifting plates 313 on adjacent second transmission belts 312 are correspondingly arranged, thereby ensuring that multiple cigarette packs in the same row can simultaneously enter the same row of lifting plates 313. The same row of cigarette packs refers to cigarette packs placed side-by-side perpendicular to the conveying direction of the second transmission belt. The lifting plate 313 is used to receive cigarette packs located at the end of the placement plate 21 that have been moved by the actuating block 223. Rotating the second transmission belt 312 allows the top surface of the lifting plate 313 to be rotated to the same plane as the top surface of the placement plate 21. This allows the cigarette pack to move from the end of the placement plate 21 in the cigarette pack moving direction to the lifting plate 313. Furthermore, to ensure smooth movement of the cigarette pack to the lifting plate 313, in some embodiments, the end of the placement plate 21 protrudes between two adjacent lifting plates 313, thereby achieving a smooth transition of the cigarette pack.

[0078] Further, refer to Figure 5 and Figure 6In this embodiment, the actuating mechanism 5 includes a third transmission assembly 51 and an actuating member 52. The third transmission assembly 51 is positioned above the target height. The third transmission assembly 51 includes two third transmission wheels 511 rotatably mounted on the frame 6, a third transmission belt 512 wound around the two third transmission wheels 511, and a third driving member 513 for driving the third transmission belt 512 to rotate around the third transmission wheels 511. The actuating member 52 has a U-shaped structure and includes a base plate 521 fixedly mounted on the third transmission belt 512. A first clamping piece 522 and a second clamping piece 523 are respectively provided on both sides of the base plate 521. The first clamping piece 522 and the second clamping piece 523 together define a clamping groove suitable for clamping a cigarette pack located at the target height. A guiding wing 524 is provided on the side of the first clamping piece 522 facing away from the base plate 521, and the end of the guiding wing 524 gradually deflects towards the side facing away from the second clamping piece 523. The third transmission assembly 51 drives the actuating member 52 to move cyclically, thereby moving the cigarette pack at the target height position to the conveyor belt 4. When the actuating member 52 actuates the cigarette pack at the target height position, the first clamping piece 522 is adapted to move the cigarette pack toward the conveyor belt 4.

[0079] To ensure that the actuating element 52 can smoothly guide the cigarette pack into the clamping slot as the third transmission belt 512 rotates, a guiding wing 524 is provided on the side of the first clamping plate 522 opposite to the base plate 521. The end of the guiding wing 524 gradually deflects towards the side opposite to the second clamping plate 523. During the movement of the actuating element 52, the guiding wing 524 can contact the cigarette pack first, guiding the cigarette pack into the clamping slot. The cigarette pack in the clamping slot is conveyed onto the transmission belt as the actuating element 52 moves. When the cigarette pack is conveyed onto the conveyor belt 4, the third driving element 513 stops operating; after the conveyor belt 4 has conveyed all the cigarette packs out of the clamping slot, the third driving element 513 restarts and repeats the actuation operation of the cigarette pack at the next target height position.

[0080] In addition, it should be noted that the length of the actuating member 52 should correspond to the number of cigarette packs so as to be able to clamp and actuate all the cigarette packs located on the lifting plate 313.

[0081] In this embodiment, the first driving component 224, the second driving component 314, and the third driving component 513 are motors or transmission mechanisms.

[0082] This embodiment also includes a controller, which is used to control the operating status of the smoke delivery mechanism 1, the conveying mechanism 2, the lifting mechanism 3 and the actuating mechanism 5, thereby realizing the interconnection between the above-mentioned mechanisms.

[0083] Example 3

[0084] Based on the same inventive concept as Embodiment 1, refer to Figure 7 and Figure 8In this embodiment, the cigarette feeding mechanism 1 includes a cigarette pack rack 11, a lifting assembly 12, and a cigarette pushing assembly 13. The cigarette pack rack 11 includes a back plate 111 and a protective plate 112. The protective plate 112 is disposed on one side of the back plate 111 opposite to the conveying mechanism 2. The back plate 111 and the protective plate 112 together define a cigarette storage chamber suitable for stacking cigarette packs. A plurality of cigarette pushing openings 113 are vertically arranged on the back plate 111, each layer corresponding to a stacked layer of cigarette packs.

[0085] refer to Figures 8 to 11 A lifting assembly 12 is mounted on the frame 6 and located on the bottom side of the cigarette pack rack 11, used to drive the cigarette pack rack 11 to move up and down. The lifting assembly 12 includes: a fixed frame 121, a support frame 122, a lifting frame 123, a first cylinder 124, and a lifting belt 125. The fixed frame 121 is fixedly mounted on the frame 6. The support frame 122 is slidably connected to the fixed frame 121, and a transmission wheel is rotatably mounted on the support frame 122. In this embodiment, the transmission wheels have multiple sets arranged in parallel, each set including two vertically arranged transmission wheels. The lifting frame 123 is slidably connected to the side of the support frame 122 opposite to the fixed frame 121, and its top is provided with an abutment plate 1231. The top surface of the abutment plate 1231 is higher than the top surface of the support frame 122, used to abut the cigarette pack rack 11. The bottom of the first cylinder 124 is fixedly mounted on the frame 6. The output end of the first cylinder 124 is connected to the support frame 122. The lifting belt 125 is fitted onto two drive wheels and located between the fixed clamp and the lifting frame 123. The length direction of the lifting belt 125 is the same as the output direction of the first cylinder 124. The fixed frame 121 and the lifting frame 123 are respectively connected to the two sides of the lifting belt 125 located on the drive wheels.

[0086] During operation, the first cylinder 124 is activated, driving the support frame 122 to move upward. Since the lifting belt 125 is connected to the fixed frame 121, as the support frame 122 moves upward, the lifting belt 125 rotates around the transmission wheel, thereby driving the lifting frame 123 connected to the other side of the lifting belt 125 to move upward. In the above structure, the upward movement distance of the lifting frame 123 includes the distance the support frame 122 moves relative to the fixed frame 121, and the distance it moves relative to the support frame 122 through the rotation of the lifting belt 125. This structure shortens the stroke of the first cylinder 124, which helps to reduce the longitudinal dimension of the entire device.

[0087] refer to Figure 12The cigarette pushing assembly 13 is mounted on the frame 6 and located on the side of the cigarette pack rack 11 facing away from the conveying mechanism 2. It is used to push cigarette packs from the cigarette pack rack 11 to the conveying mechanism 2 through the cigarette pushing port 113. The cigarette pushing assembly 13 includes a linear module 131, a support 132, and a cigarette pushing component 133. The linear module 131 is mounted on the frame 6; in this embodiment, the linear module 131 uses a KENIX K45A precision slide module. The support 132 is connected to the slide of the linear module 131. The cigarette pushing component 133 includes a push rod 1331, one end of which is connected to the support 132, and the other end is connected to a push plate 1332. The push plate 1332 slides through the cigarette pushing port 113 to push out cigarette packs from the cigarette storage chamber. The cigarette packs are stacked in layers in the cigarette storage chamber, with each layer corresponding to a cigarette pushing port 113. The cigarette pushing assembly 13 can push the entire layer of cigarette packs to the conveying mechanism 2 through the cigarette pushing port 113. The coordinated lifting component 12 can drive the cigarette pack rack 11 to move up and down, and the cigarette pushing component 13 can push the cigarette packs layer by layer.

[0088] Specifically, after the cigarette packs are stacked in layers in the cigarette storage bin, they are lifted by the lifting assembly 12 to the position corresponding to the topmost cigarette push port 113 and the push plate 1332. At this point, the lifting operation stops; simultaneously, the slide of the linear module 131 moves, causing the push plate 1332 to pass through the topmost cigarette push port 113 and push the topmost cigarette pack to the conveying mechanism 2. After the topmost cigarette pack is pushed, the slide drives the push rod 1331 to reset, and the lifting assembly 12 operates again to lift the next layer's cigarette push port 113 to the position corresponding to the push plate 1332, and repeats the above pushing steps to realize the layer-by-layer pushing of cigarette packs.

[0089] Example 4

[0090] Based on the same inventive concept as Embodiment 3, refer to Figure 8 and Figure 13 In this embodiment, when the number of cigarette packs is large and the storage compartment of one cigarette pack rack 11 cannot hold them all, the operator needs to place the next stack of cigarette packs on the lifting assembly 12 after pushing the cigarette packs in one cigarette pack rack 11. This process is rather cumbersome. In this embodiment, the cigarette feeding assembly also includes a fourth transmission assembly 14 and a recovery assembly 15, which enable automatic loading and unloading of the cigarette pack rack 11.

[0091] The fourth transmission assembly 14 is used to store the cigarette pack rack 11 and can move the stored cigarette pack rack 11 directly above the lifting assembly 12. Specifically, there are two fourth transmission assemblies 14, which are disposed on the frame 6 and symmetrically arranged on both sides of the lifting assembly 12. Each fourth transmission assembly 14 includes: two fourth transmission wheels 141 rotatably disposed on the frame 6, a fourth transmission belt 142 wound around the two fourth transmission wheels 141, and a fourth driving member for driving the fourth transmission belt 142 to rotate around the fourth transmission wheels 141.

[0092] In use, the operator can place multiple cigarette pack racks 11 filled with cigarette packs onto the fourth transmission belt 142. After the cigarette packs in the previous cigarette pack rack 11 have been pushed out, the cigarette pack rack 11 can be removed and the lifting assembly 12 can be reset. At this time, the fourth drive unit is activated to move the next cigarette pack rack 11 to the top surface of the lifting assembly 12, thereby changing the cigarette pack rack 11.

[0093] In some embodiments, to prevent the cigarette pack rack 11 from shifting during transport, two parallel guide rails 61 are provided on the frame 6. The guide rails 61 are arranged parallel to the fourth transmission belt 142. Guide rail grooves 61 are provided on both sides of the cigarette pack rack 11, respectively, to mate with the two guide rails 61. The engagement of the guide rail grooves with the guide rails 61 prevents the cigarette pack rack 11 from shifting during transport.

[0094] Furthermore, to ensure the cigarette pack rack 11 can move precisely above the lifting assembly 12 and thus guarantee the stability of the lifting process, in some embodiments, a baffle 62 is provided on the frame 6. The baffle 62 is positioned above the fourth transmission assembly 14 and parallel to the cigarette pack rack 11. When the cigarette pack rack 11 moves to contact the baffle 62, the lifting assembly 12 is located directly below the cigarette pack rack 11. Further, the top surface of the baffle 62 is in contact with the bottom surface of the placement plate 21. During the lifting process, the space formed by the baffle 62 and the cigarette pack rack 11 prevents cigarette packs from scattering.

[0095] Further, refer to Figure 13 The recycling component 15 is used to unload the cigarette pack rack 11 after the cigarette packs have been pushed out of the lifting component 12. Specifically, the recycling component 15 includes a pull-out component 151 and a conveyor component 152.

[0096] The pull-out component 151 is used to pull the cigarette pack rack 11, after the cigarette pack has been pushed, away from the top of the lifting assembly 12. Specifically, the pull-out component 151 includes a second cylinder 1511, which is disposed on the frame 6 and has the same output direction as the linear module 131. The output end of the second cylinder 1511 is provided with a support rod 1512 whose length direction is perpendicular to the output direction of the second cylinder 1511. Pull plates 1513 are respectively provided at both ends of the support rod 1512. The length direction of the pull plate 1513 is the same as the output direction of the second cylinder 1511. In some embodiments, a slide rail is provided on the frame 6, and a slide groove is provided on the pull plate to slide in connection with the slide rail, thereby ensuring the stability of the movement of the pull plate. The end of the pull plate 1513 opposite to the support rod 1512 has a hook head, which is located on the top surface of the pull plate 1513. When the lifting assembly 12 raises the cigarette pack rack 11 to the top, the hook head is lower than the bottom surface of the cigarette pack rack 11 in the horizontal direction; and at this time, the lifting assembly 12 is located between the output direction of the second cylinder 1511 and the pull plate 1513.

[0097] In use, after the cigarette pusher pushes the last layer of cigarette packs out of the cigarette pack rack 11, the second cylinder 1511 drives the support rod 1512 to move the pull plate 1513 towards the cigarette pack rack 11, until it is below the cigarette pack rack 11; at this time, the lifting assembly 12 is located between the pull plates 1513. As the lifting assembly 12 descends, the cigarette pack rack 11 falls onto the pull plate 1513; at this time, the second cylinder 1511 drives the pull plate 1513 to reset, and under the action of the hook head, the cigarette pack rack 11 will move away from the top of the lifting assembly 12 along with the pull plate 1513.

[0098] Furthermore, the conveyor 152 is used to receive the cigarette pack rack 11 pulled out by the pull-out member 151 and to transport and store the cigarette pack rack 11. Specifically, the conveyor 152 includes: two fifth drive wheels rotatably mounted on the frame 6, a fifth drive belt wound around the fifth drive wheels, and a fifth drive member for driving the fifth drive belt to rotate around the fifth drive wheels. The top surface of the fifth drive belt is flush with the top surface of the pull plate, and the pull plate can pull the cigarette pack rack 11 onto the fifth drive belt. Under the action of the hook head, the cigarette pack rack 11 will move with the pull plate 1513 to above the fifth drive belt. Multiple cigarette pack racks 11 can be stored sequentially via the conveyor 152, realizing the recycling of the cigarette pack racks 11.

[0099] In this embodiment, the fourth and fifth driving components are motors or transmission mechanisms.
