Description

Technical Field

[0001] This application relates to the technical field of cigarette packaging equipment, and in particular to a side-opening cigarette packaging machine. Background Art

[0002] With the continuous improvement of the market's requirements for the quality of cigarette products, it is particularly important to maintain the quality parameters such as the taste, aroma, and moisture of cigarette products during storage, transportation, and use.

[0003] In related technologies, cigarette packaging mainly uses aluminum foil as the inner lining material and achieves sealing through heat sealing or mechanical folding.

[0004] In view of the above related technologies, although aluminum foil can block part of the oxygen and moisture, its heat-sealing layer is prone to tiny gaps due to friction or high-temperature environments during long-term storage and transportation, resulting in the overflow of cigarette aroma or moisture absorption. When aluminum foil is combined with a supporting sealing process (such as heat-shrinkable film), high-temperature treatment (such as a 145°C heat shrinker) is required, which not only consumes a large amount of energy but also may damage the breathable filter rod structure of the cigarette filter tip and affect the taste stability. Therefore, it is necessary to provide a cigarette packaging device with high sealing performance, aroma preservation, and moisture retention to improve the technical limitations such as insufficient sealing performance and poor material compatibility in the traditional aluminum foil packaging method. Summary of the Invention

[0005] In order to improve the problems of insufficient sealing performance and poor material compatibility in the traditional aluminum foil packaging method, this application provides a side-opening cigarette packaging machine.

[0006] The side-opening cigarette packaging machine provided by this application adopts the following technical solutions: A side-opening cigarette packaging machine includes a cigarette supply mechanism for inputting and arranging cigarettes, a frame paper conveying and folding mechanism for inputting frame paper and folding a single sheet of frame paper outside the cigarettes, a heat-sealing film fixed-length cutting and conveying mechanism for performing fixed-length cutting on the heat-sealing film and conveying a single sheet of heat-sealing film, a heat-sealing film folding and heat-sealing mechanism for folding a single sheet of heat-sealing film outside the frame cigarette pack and heat-sealing it, and a main frame and a sub-frame for arranging each mechanism in sequence.

[0007] By adopting the above technical solutions, the cigarette supply mechanism is responsible for inputting and precisely arranging cigarettes, providing a neat and orderly cigarette group for subsequent packaging processes. The frame paper conveying and folding mechanism can accurately fold a single sheet of frame paper outside the cigarette group to form a relatively enclosed basic packaging structure, which plays a role in initially fixing and protecting the cigarette group and provides a basis for subsequent sealing processes. The heat-sealing film fixed-length cutting and conveying mechanism can perform fixed-length cutting and conveying on the heat-sealing film, ensuring that the length of the heat-sealing film is accurate and consistent, enabling the heat-sealing film to match the frame paper and providing guarantee for subsequent heat-sealing processes. The heat-sealing film folding and heat-sealing mechanism folds a single sheet of heat-sealing film outside the frame cigarette package and performs heat-sealing, which is a key step to achieve packaging tightness. Through the folding and heat-sealing processes, it is ensured that there is a tight fit between the heat-sealing film and the frame paper, forming a completely sealed packaging body to prevent the leakage of cigarette aroma and the intrusion of external moisture. The side-opening cigarette packaging machine uses a new film for heat-sealing, replacing the aluminum foil paper in the original cigarette packaging, thereby completing the inner lining paper packaging of cigarette cigarettes. At the notch for extracting cigarettes, an adhesive seal head is pasted to achieve complete sealing of the cigarette packaging during storage, transportation, and use, so as to achieve the purpose of preserving the fragrance and moisture of cigarette cigarettes.

[0008] Further, the cigarette supply mechanism includes a cigarette magazine provided on the main frame and used for arranging the cigarette group, a cigarette group conveyor belt provided on the main frame and located below the cigarette magazine, and a flipping and pushing assembly used for pushing the cigarette group into the frame paper conveying and folding mechanism. The main frame is provided with a first pushing table and a first supporting plate installed on the first pushing table. The pushing direction of the first pushing table is perpendicular to the conveying direction of the cigarette group conveyor belt. The first supporting plate is driven by the first pushing table to approach / leave the position below the outlet of the cigarette magazine to receive the cigarettes falling from the cigarette magazine. A number of cigarette group receiving hoppers are arranged at equal intervals on the cigarette group conveyor belt. The width of the cigarette group receiving hopper matches the width of the supporting plate. The inner wall of the cigarette group receiving hopper is provided with limit blocks for cooperating with the number of cigarettes in each row of the cigarette group.

[0009] By adopting the above technical solution, the cigarette magazine arranges the cigarettes neatly, the cigarette group conveyor belt accurately conveys the cigarettes to the designated position, and the flipping and pushing assembly then pushes the cigarette group into the subsequent mechanism, improving the stability and accuracy of cigarette conveyance and laying a foundation for the subsequent packaging process. The setting of the first pushing table and the first supporting plate on the main frame enables the supporting plate to approach or move away from the cigarette magazine outlet as needed, flexibly adjust the position, and better receive the cigarettes falling from the cigarette magazine. The cigarette group receiving hoppers arranged at equal intervals on the cigarette group conveyor belt and the design matching the width of the supporting plate ensure the stability and consistency of the cigarettes during conveyance. The design of the cigarette limiting blocks on the inner wall of the receiving hopper can effectively limit the number of cigarettes in each row, ensure the regularity of the cigarette group, and improve the packaging quality. The overall mechanism improves the efficiency and precision of cigarette conveyance, reduces the damage and displacement of cigarettes during conveyance, ensures the smooth progress of the subsequent packaging process, and thus enhances the performance and reliability of the entire packaging equipment.

[0010] Further, the flipping and pushing assembly is arranged on the main frame and adjacent to the frame paper conveying and folding mechanism. The main frame is provided with a second pushing table for pushing the cigarette group in the cigarette group receiving hopper into the flipping and pushing assembly and a second pushing plate installed on the second pushing table. The flipping and pushing assembly is arranged on the main frame and adjacent to the frame paper conveying and folding mechanism. The main frame is provided with a second pushing table for pushing the cigarette group in the cigarette group receiving hopper into the flipping and pushing assembly and a second pushing plate installed on the second pushing table.

[0011] By adopting the above technical solution, the flipping and pushing assembly is adjacent to the frame paper conveying and folding mechanism, enabling the cigarette group to be quickly and accurately pushed from the cigarette group receiving hopper into the flipping and pushing assembly, reducing the moving distance and time of the cigarette group during conveyance, and improving the packaging efficiency. The setting of the second pushing table and the second pushing plate makes the pushing and receiving of the cigarette group more stable and reliable. The flipping and pushing assembly flips the cigarette group, and the coordinated actions with the cigarette group conveyor belt and the frame paper conveying and folding mechanism are more smooth and efficient. The cooperation between components is closer, reducing the pausing and adjustment time of the cigarette group during conveyance and packaging. The flipping and pushing assembly pushes the cigarette group into the frame paper conveying and folding mechanism, providing accurate positioning and support for the folding of the frame paper, enabling the frame paper to tightly wrap around the outside of the cigarette group and form a regular frame cigarette pack.

[0012] Further, the flipping and pushing assembly includes a flipping wheel shaft rod arranged on the main frame, at least two cigarette group placement plates symmetrically arranged up and down on the flipping wheel shaft rod, a plurality of flipping claws arranged outside the two cigarette group placement plates and used for clamping the cigarette group, and a third pushing table for pushing the cigarette group on the cigarette group placement plate into the frame paper conveying and folding mechanism. A cigarette group gap for placing the cigarette group is formed between the two cigarette group placement plates.

[0013] By adopting the above technical solution, the flipping and pushing component realizes the stable pushing and accurate transfer of the cigarette group through the coordinated work of the flipping axle rod, the symmetrically arranged upper and lower cigarette group placement plates, the flipping grippers, and the third pushing table. The flipping axle rod, as the core component, drives the flipping of the cigarette group placement plates and the flipping grippers. The symmetrically arranged upper and lower cigarette group placement plates provide a stable support platform for the cigarette group, ensuring that the cigarette group remains horizontal during the pushing process without displacement or tilt. The flipping grippers are installed outside the cigarette group placement plates and firmly fix the cigarette group on the placement plates through clamping actions, preventing loosening or scattering during the pushing process and ensuring the integrity of the cigarette group. When the cigarette group is pushed to the frame paper conveying and folding mechanism, the third pushing table accurately pushes the cigarette group from the cigarette group placement plate into the frame paper conveying and folding mechanism, ensuring the precise docking of the cigarette group and the frame paper, providing a good start for the subsequent folding process, improving the continuity and stability of the pushing, reducing the pausing and adjustment time of the cigarette group during the pushing process, and thus improving the overall packaging efficiency.

[0014] Furthermore, the frame paper conveying and folding mechanism includes a frame paper storage bin provided on the main frame for storing frame paper, a suction wheel rotatably connected to the main frame and located below the frame paper storage bin for picking up a single sheet of frame paper, a frame paper conveyor provided on the main frame and arranged in the vertical direction, and a packaging wheel assembly provided on the side of the frame paper conveyor away from the flipping and pushing component. The packaging wheel assembly has a plurality of circumferentially arranged conveying slots for inserting cigarette packs. A cigarette group through slot for the cigarette group to pass through is formed on the frame paper conveyor, and the cigarette group through slot is respectively aligned with the conveying slots and the cigarette group gap.

[0015] By adopting the above technical solution, the frame paper conveying and folding mechanism realizes the precise conveying and folding of the frame paper through the coordinated work of the frame paper storage bin, the suction wheel, the frame paper conveyor, and the packaging wheel assembly. The frame paper storage bin stores the frame paper, the suction wheel picks up a single sheet of frame paper, the frame paper conveyor conveys the frame paper in the vertical direction, and the conveying slots of the packaging wheel assembly are precisely docked with the cigarette group through slots on the frame paper conveyor, ensuring the precise cooperation of the cigarette group and the frame paper, improving the stability and accuracy of the frame paper conveying, and enabling the cigarette group to be smoothly inserted into the frame paper. The plurality of circumferentially arranged conveying slots of the packaging wheel assembly and the precise alignment of the cigarette group through slots on the frame paper conveyor with the conveying slots and the cigarette group gap ensure the stability and accuracy of the cigarette group during the conveying process, avoid the offset or jamming of the cigarette group during the conveying process, and improve the packaging quality.

[0016] Furthermore, a frame cigarette pack conveyor belt for cooperating with the packaging wheel assembly is provided on the main frame in the horizontal direction. The packaging wheel assembly further includes a fourth pushing table and a fourth pushing rod provided on the fourth pushing table. The fourth pushing rod is located inside the conveying slot and its end is aligned with the frame cigarette pack conveyor belt.

[0017] By adopting the above technical solution, the packaging wheel assembly improves the efficiency and quality of cigarette pack conveying and subsequent processes through the frame cigarette pack conveyor belt, the fourth pushing table and the fourth pushing rod. The frame cigarette pack conveyor belt is responsible for smoothly conveying the packaged cigarette packs to the next process, ensuring the continuity of the production process. The setting of the fourth pushing table and the fourth pushing rod ensures that the cigarette groups can be accurately pushed into the conveying slots of the packaging wheel assembly. The fourth pushing rod is located in the conveying slot and its end is aligned with the frame cigarette pack conveyor belt. The precise pushing mechanism ensures the stability of the cigarette groups during the transfer process, avoiding deformation or scattering of the cigarette groups caused by improper pushing and further improving the packaging quality.

[0018] Furthermore, the auxiliary frame is arranged adjacent to and perpendicular to the main frame, and the heat-sealed film fixed-length cutting and conveying mechanism is arranged on the auxiliary frame; The heat-sealed film fixed-length cutting and conveying mechanism includes a heat-sealed film paper library arranged on the side wall of the auxiliary frame for placing and feeding out the heat-sealed film reel, a plurality of conveying rollers dispersed on the auxiliary frame for the heat-sealed film to pass through in a wound state, a first heat-sealed film conveying rack for the heat-sealed film to pass through in a flat state, a cutting assembly arranged on the auxiliary frame and below the first heat-sealed film conveying rack for fixed-length cutting of the heat-sealed film, and a second heat-sealed film conveying rack arranged below the cutting assembly for conveying single sheets of heat-sealed film. The second heat-sealed film conveying rack is provided with a cigarette pack through slot for the frame cigarette pack to pass through and aligned with the heat-sealed film folding and heat-sealing mechanism. On the main frame, there is a fifth pushing table and a fifth pushing rod for pushing the cigarette packs on the frame cigarette pack conveyor belt into the cigarette pack through slot. The pushing direction of the fifth pushing rod is perpendicular to the conveying direction of the frame cigarette pack conveyor belt.

[0019] By adopting the above technical solution, the heat-sealed film paper library provides a stable placement and film feeding environment for the heat-sealed film reel, ensuring the stable supply of the heat-sealed film. The plurality of conveying rollers are dispersed, enabling the heat-sealed film to pass through smoothly in a wound state, avoiding slack or wrinkles of the film during conveying. The first heat-sealed film conveying rack ensures that the heat-sealed film passes through in a flat state, providing a basis for subsequent cutting and heat-sealing processes. The cutting assembly can accurately perform fixed-length cutting on the heat-sealed film, ensuring that the length of each sheet of heat-sealed film is consistent and meeting the requirements of the packaging process. The second heat-sealed film conveying rack is responsible for conveying single sheets of heat-sealed film and is also aligned with the heat-sealed film folding and heat-sealing mechanism by opening the cigarette pack through slot, ensuring that the frame cigarette pack can pass through smoothly and be accurately docked with the heat-sealed film. The fifth pushing table and the fifth pushing rod on the main frame accurately push the cigarette packs on the frame cigarette pack conveyor belt into the cigarette pack through slot, and their pushing direction is perpendicular to the conveying direction of the frame cigarette pack conveyor belt, ensuring the stability of the cigarette packs during the transfer process.

[0020] Furthermore, the heat-sealing film folding and heat-sealing mechanism includes a heat-sealing wheel assembly for heat-sealing the heat-sealing film to the outside of the frame cigarette pack and a sixth pushing assembly for pushing the heat-sealed film cigarette pack out of the heat-sealed wheel assembly, the heat-sealing wheel assembly includes a heat-sealing forming wheel rotatably connected to the sub-frame, a bottom heat-sealing plate provided on the heat-sealing forming wheel and used for heat-sealing the heat-sealing film at the bottom of the frame cigarette pack, a side heat-sealing plate provided on the heat-sealing forming wheel and used for heat-sealing the heat-sealing film on the side of the frame cigarette pack, and a plurality of electric heating blocks for cooperating with the bottom heat-sealing plate and the side heat-sealing plates, a plurality of cigarette pack fixing grooves for inserting and placing the frame cigarette packs are circumferentially arranged on the heat-sealing forming wheel, and the cigarette pack fixing groove on the side of the heat-sealing film conveying rack close to the heat-sealing film conveying rack is aligned with the cigarette pack through groove.

[0021] By adopting the above technical solution, the heat-sealing wheel assembly heat-seals the bottom and side heat-sealing films of the frame cigarette pack through the bottom heat-sealing plate and the side heat-sealing plate. The electric heating block provides stable heat to ensure uniform heat-sealing temperature, plasticize the heat-sealing film and form a firm sealing structure to prevent the aroma of the cigarette from leaking out and getting damp, thereby improving the packaging quality. Multiple cigarette pack fixing grooves are arranged circumferentially on the heat-sealing forming wheel, and multiple frame cigarette packs can be heat-sealed at the same time. The sixth pushing component pushes the heat-sealed cigarette pack out of the heat-sealing wheel assembly to prevent the cigarette pack from staying in the heat-sealing wheel for too long.

[0022] Furthermore, it also includes a heat-sealed film cigarette pack output mechanism for transferring the heat-sealed film cigarette pack of the heat-sealed forming wheel to the subsequent station, the heat-sealed film cigarette pack output mechanism includes a first conveying trough, a second conveying trough, a cigarette pack moving belt assembly and a seventh pushing assembly, the first conveying trough is arranged on the side wall of the main frame and is located between the main frame and the heat-sealed forming wheel for receiving the heat-sealed film cigarette pack, and the first conveying trough is provided with a pack passing gap for the heat-sealed film cigarette pack to pass through on the side wall away from the main frame.

[0023] By adopting the above technical solution, the first conveyor trough is arranged on the side wall of the main frame and between the main frame and the heat-sealing forming wheel, and is used to receive the heat-sealed film cigarette packs, ensuring that the heat-sealed cigarette packs can smoothly enter the first conveyor trough. The second conveyor trough transfers the cigarette packs from the first conveyor trough to the subsequent station, and the cooperation of the two conveyor troughs ensures the smooth transition of the cigarette packs between different stations. The seventh push component works in conjunction with the cigarette pack shifting belt component to ensure that the cigarette packs can be accurately pushed to the designated position during the conveying process.

[0024] Furthermore, the second conveying trough is perpendicular to the first conveying trough, the first conveying trough is provided with a cigarette pack outlet for communicating with the interior of the second conveying trough on a side wall near the end of the second conveying trough, and the first conveying trough is provided with a cigarette pack pushing port for cooperating with the seventh pushing assembly on a side opposite to the cigarette pack outlet; The cigarette pack moving belt assembly is arranged on the main frame and located above the first conveying groove to move the heat-sealed film cigarette packs in the first conveying groove.

[0025] By adopting the above technical solution, the second conveying trough is perpendicular to the first conveying trough, and the side wall of the first conveying trough near the end of the second conveying trough is provided with a cigarette pack outlet, which is connected to the inside of the second conveying trough to ensure that the cigarette pack can smoothly enter the second conveying trough. The first conveying trough is provided with a cigarette pack push port on the opposite side of the cigarette pack outlet, and the seventh push component pushes the cigarette pack in the first conveying trough through the cigarette pack push port, and the cigarette pack moving belt component moves the cigarette pack above the first conveying trough to assist its movement. Ensure that the cigarette pack can be accurately pushed to the designated position in the first conveying trough and smoothly enter the second conveying trough, avoid the deviation or jamming of the cigarette pack during the transfer process, and improve the continuity and stability of the packaging process.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The cigarette supply mechanism arranges the cigarettes accurately and conveys them to the frame paper conveying and folding mechanism. The frame paper conveying and folding mechanism uses a suction wheel to pick up a single frame paper from the frame paper library and conveys it to the packaging wheel assembly through the frame paper conveyor rack. The conveying slot of the packaging wheel assembly is precisely docked with the cigarette group slot on the frame paper conveyor rack to ensure the precise fit of the cigarette group and the frame paper, forming a relatively closed basic packaging structure. The heat-sealing film fixed-length cutting and conveying mechanism cuts the heat-sealing film to a fixed length and conveys it to the heat-sealing film folding and heat-sealing mechanism, which heat-seals the bottom and side heat-sealing films of the frame cigarette pack through the bottom heat-sealing plate and the side heat-sealing plate. The electric heating block provides stable heat to ensure uniform heat sealing temperature, so that the heat-sealing film and the frame paper fit tightly together to form a completely sealed packaging body, effectively preventing the leakage of cigarette aroma and the intrusion of external moisture, thereby improving packaging quality; 2. Use new films instead of traditional aluminum foil as packaging materials to avoid the problem of tiny gaps in aluminum foil caused by friction or high temperature environment during long-term storage and transportation, so as not to damage the breathable filter rod structure of the cigarette filter and affect the stability of the taste. The heat-sealing film paper warehouse in the heat-sealing film fixed-length cutting and conveying mechanism provides a stable placement and film-discharging environment for the heat-sealing film roll. Multiple conveying rollers are arranged in a dispersed manner so that the heat-sealing film can pass smoothly in a winding posture, avoiding the film from loosening or wrinkling during the conveying process. The first heat-sealing film conveying rack ensures that the heat-sealing film passes in a flat posture, providing a guarantee for the subsequent cutting and heat-sealing processes. The cutting assembly can accurately cut the heat-sealing film to a fixed length, ensuring that the length of each heat-sealing film is consistent and meets the requirements of the packaging process. The second heat-sealing film conveying rack is responsible for conveying a single heat-sealing film, and by opening a cigarette pack through slot and aligning it with the heat-sealing film folding and heat-sealing mechanism, it ensures that the frame cigarette pack can pass smoothly and accurately dock with the heat-sealing film, thereby improving the compatibility between materials and the stability of packaging; 3. The heat-sealed film cigarette pack output mechanism realizes the efficient transfer and accurate pushing of the heat-sealed film cigarette pack through the coordinated work of the first conveyor trough, the second conveyor trough, the cigarette pack shifting belt assembly and the seventh pushing assembly, ensuring the continuity and stability of the production process. The various mechanisms of the side-opening cigarette packaging machine have a high degree of automation, which improves packaging efficiency and production speed, reduces labor costs, and makes the entire packaging process smoother and more efficient.

In this embodiment, the number of the first support plates 112 is three, and the directions of the three support plates are perpendicular to the side wall of the main frame 6. The three support plates are arranged on the first push platform 111 at intervals and in a stepped arrangement. The pushing direction of the first push platform 111 is perpendicular to the conveying direction of the cigarette group conveyor belt 12. The three first support plates 112 are driven by the first push platform 111 to approach / move away from the lower position of the cigarette storage 11 outlet, thereby receiving the cigarettes dropped from the cigarette storage 11 and pushing the cigarettes onto the cigarette group conveyor belt 12.
