Description

Technical Field

[0001] This utility model relates to the field of tobacco packaging technology, and in particular to a cigarette packaging anti-bubbling device. Background Technology

[0002] In the tobacco industry, customers' cigarettes are often packaged and then stacked according to the required packaging quantity using specialized equipment. Different quantities of cigarette stacks are then packaged by packaging equipment before being sold to various regions.

[0003] Existing cigarette packaging equipment typically involves conveying the cigarette stack via a conveyor belt to a pushing structure, which then propels it forward. The stack is covered with a wrapping film, and a pressure plate above the other side of the conveyor belt presses down on the cigarette stack to secure it. A cutter then cuts along the edge of the cigarette stack to sever the wrapping film. The cigarette stack, along with the wrapping film, then moves forward to a thermoforming device for wrapping and thermoforming, completing the packaging process.

[0004] However, the current equipment has certain problems. When business volume is high, in order to ensure sufficient supply, the speed parameters of the equipment are often adjusted to be faster. Once the speed is increased, the rapid pressing of the pressure plate can easily cause bubbling in front of the cigarette pile due to air pressure, thus wasting excessive wrapping material and increasing the packaging cost of cigarettes. At the same time, because the current equipment lacks baffles or other devices between the cigarettes and the heating chamber, shorter irregularly shaped cigarettes on the upper layer of the cigarette pile cannot be pressed down by the pressure plate due to their length. They will move forward in the wrapping due to inertia, further leading to excessive use of wrapping material. Summary of the Invention

[0005] The purpose of this invention is to overcome the defects of the existing technology and provide a cigarette packaging anti-bubbling device.

[0006] The objective of this utility model can be achieved through the following technical solutions: A cigarette packing anti-bubbling device includes a first conveyor platform and a second conveyor platform vertically arranged. A pushing cylinder is mounted on the first conveyor platform. A pushing plate is mounted on the pushing cylinder to push the cigarette pile onto the second conveyor platform. From right to left, a coating mechanism, a pressing cylinder, and a limiting plate are arranged sequentially on the second conveyor platform. The coating mechanism includes a cutting cylinder mounted on the left side, with a cutting blade connected to its lower end for cutting the coating. The cutting blade cuts close to the edge of the cigarette pile. A pressing plate is connected to the lower end of the pressing cylinder for pressing down on the cigarette pile. The limiting plate is fixed to a round rod. A bracket is also mounted on the second conveyor platform. A limiting cylinder is mounted on the top of the bracket, with its telescopic end passing through the top of the bracket. The round rod is connected to the telescopic end of the limiting cylinder. A first sensor is mounted on the side of the limiting plate, and a second sensor is mounted on its bottom. A controller is mounted on the bracket. The controller is electrically connected to the limiting cylinder, the first sensor, and the second sensor.

[0007] Furthermore, the film coating mechanism also includes a film wrapping frame on the right side; the film wrapping frame is equipped with a film wrapping roller, a first guide roller and a second guide roller; the film wrapping roller is wound with a wrapping film; the wrapping film passes sequentially through the lower surface of the first guide roller and the upper surface of the second guide roller, passes through the top of the film coating mechanism and covers the lower outlet of the film coating mechanism.

[0008] Furthermore, a notch is provided on the second conveyor platform; the cutter cuts into the notch after it cuts down.

[0009] Furthermore, the end of the first conveyor is provided with a baffle to prevent smoke from escaping.

[0010] Furthermore, symmetrical extrusion cylinders are provided on both sides of the second conveyor platform; each of the extrusion cylinders is provided with an extrusion side plate for extruding the smoke pile to the side.

[0011] Compared with the prior art, the present invention has the following advantages: This invention features a limiting plate, controlled by a limiting cylinder, positioned in front of the fixed location of the tobacco pile. After the tobacco pile is pushed to its position by the push plate, the plate blocks the movement in front of it. This eliminates the space for the wrapping film to bubble forward due to air pressure and prevents the top cigarettes (especially irregularly shaped cigarettes) from shifting and sliding off the edge of the tobacco pile. This prevents bubbling and waste of wrapping film caused by the sliding of the upper cigarettes, thus saving wrapping film resources and reducing production costs. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0016] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0017] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this utility model and simplifying the description, 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 this utility model.

[0018] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0019] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted. Example

[0020] like Figure 1 and 2As shown, a cigarette packaging anti-bubbling device includes a vertically arranged first conveyor platform 1 and a second conveyor platform 2. Both the first and second conveyor platforms 1 and 2 are equipped with conveyor belts for conveying cigarette stacks. One end of the first conveyor platform 1 is connected to a cigarette dispensing device, and one end of the second conveyor platform 2 is connected to a thermoforming device. The cigarette dispensing device conveys the stacked cigarette stacks to the first conveyor platform 1, and the second conveyor platform 2 conveys the cigarette stacks covered with film to the thermoforming device for thermoforming packaging. A pushing cylinder 3 is installed on the first conveyor platform 1. The pushing cylinder 3 is equipped with a pushing plate 4 for pushing the cigarette stacks onto the second conveyor platform 2. The second conveyor platform 2 has a conveyor belt from right to left... The system is sequentially equipped with a film-coating mechanism, a pressing cylinder 5, and a limiting plate 6. The film-coating mechanism includes a cutting cylinder 7 located on the left side, with a cutting blade 8 connected to its lower end for cutting the film. The cutting blade 8 cuts close to the edge of the tobacco pile. A notch 17 is provided on the second conveyor table 2. After cutting, the cutting blade 8 cuts into the notch 17, pulling the film down with it until it is cut within the notch 17. This ensures that the cut film still covers the lower outlet of the film-coating mechanism, without affecting the film-coating of the next tobacco pile. A pressing plate 9 is connected to the lower end of the pressing cylinder 5 for pressing down on the tobacco pile when it reaches the bottom. The second conveyor platform 2 is equipped with symmetrical compression cylinders 19 on both sides to prevent movement of the smoke pile. Each compression cylinder 19 has a compression side plate 20 at its end for pressing against the side of the smoke pile. The compression cylinders 19 and the pressing cylinder 5 operate synchronously, with the compression side plates 20 pressing against the side of the smoke pile to facilitate cutting by the cutter. A limiting plate 6 is fixed to a round rod 10. A support 11 is also provided on the second conveyor platform 2. A limiting cylinder 12 is installed at the top of the support 11, with its telescopic end passing through the top of the support 11. The round rod 10 is connected to the telescopic end of the limiting cylinder 12. A first sensor is installed on the side of the limiting plate 6. 21. A second sensor 22 is provided at the bottom; a controller 23 is provided on the bracket 11 to receive signals from the first sensor 21 and the second sensor 22 and control the lifting and lowering of the limit cylinder 12; the controller 23 is electrically connected to the limit cylinder 12, the first sensor 21 and the second sensor 22 respectively. When the tobacco pile is pressed on the conveyor belt, the limit plate 6 is pressed against the front of the tobacco pile. This can eliminate the space for the wrapping film to bubble forward due to air pressure, and also prevent the top cigarettes (especially irregular cigarettes) from sliding out of the edge of the tobacco pile, thereby preventing the generation of bubbles and the waste of wrapping film caused by the sliding of the upper cigarettes, saving wrapping film resources and reducing production costs.

[0021] The coating mechanism also includes a wrapping frame 13 on the right side; the wrapping frame 13 is equipped with a wrapping roller 14, a first guide roller 15, and a second guide roller 16; the wrapping roller 13 is wound with packaging film (not shown in the figure); the packaging film passes sequentially through the lower surface of the first guide roller 15 and the upper surface of the second guide roller 16, passes through the top of the coating mechanism and covers the lower outlet of the coating mechanism. A wrapping channel (not shown in the figure) is provided above the coating mechanism. The wrapping film passes through this channel and is pulled and extended when the cutter 8 cuts down, thereby ensuring that there is always wrapping film at the lower outlet of the coating mechanism. When the tobacco pile is pushed over next time, it will move forward and cover the tobacco pile, thus completing the coating and packaging.

[0022] To prevent workers from accidentally putting their hands into the device, a protective baffle 18 is provided at the end of the first conveyor 1.

[0023] The device of this utility model is equipped with a control terminal, which is used to adjust the operating parameters of each component, thereby controlling the operating speed and ensuring that the operating process is executed smoothly in sequence.

[0024] The working principle of this utility model is as follows: First, the tobacco pile is conveyed from the smoke outlet to the conveyor belt on the first conveyor platform 1 at certain intervals according to the set speed parameters. It is then carried forward by the conveyor belt to the end of the first conveyor platform 1. Then, the push cylinder 3 drives the push plate 4 to push the tobacco pile towards the second conveyor belt 2. When the tobacco pile passes the outlet below the coating mechanism, its bottom edge presses against the coating film, thus covering the surface with a layer of film. When the tobacco pile and coating film are pushed together to the area below the pressing cylinder 5, the pressing cylinder 5 quickly controls the pressure plate 9 to press down on the tobacco pile on the second conveyor platform 2, preventing the tobacco pile from being conveyed away. At this time, the two extrusion cylinders 19 also control the extrusion side plates 20 to press down on the sides of the tobacco pile. When the tobacco pile is pressed down, one side is exactly against the limiting plate 6. Thus, when the pressure plate 9 presses down, the limiting plate 6 prevents the coating film from blowing and bubbling. The other side of the pile is right at the edge of the notch 17. Then, the cutting cylinder 7 controls the cutting blade 8 to cut down. The cutting blade 8 cuts down along the edge of the tobacco pile into the notch 17, thus cutting off the wrapping film. Then, the cutting cylinder 7, the pushing cylinder 3, the pressing cylinder 5, and the squeezing cylinder 19 all reset. When the first sensor 21 on the front side of the limiting plate 6 touches the tobacco pile, it sends a signal to the controller 23. The controller 23 controls the limiting cylinder 12 to start and drive the limiting plate 6 to rise, so that the tobacco pile passes through the bottom. The tobacco pile continues to be carried forward by the conveyor belt to the final thermoplastic equipment for thermoplastic molding. During this process, the second sensor 22 at the bottom of the limiting plate 6 senses the passage of the tobacco pile and sends a signal to the controller 23. At this time, the controller 23 will control the limiting cylinder 12 to start and drive the limiting plate 6 to press down, and the cycle will continue for the next packaging operation.

[0025] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
