[0050] like Figure 1-Figure 3 As shown, in this embodiment, the cigarette box labeling device includes a conveying mechanism 1, a frame 2, a supply assembly 3, a transmission mechanism 4, and a detection assembly 5. The conveying mechanism 1 is used to convey cigarette boxes 100, and the frame 2 is located next to the conveying mechanism 1. The supply assembly 3 includes a label 31, a printer 32, and a winding roller 33. The winding roller 33 and the printer 32 are both mounted on the frame 2. One end of the label 31 is connected to the winding roller 33, and the other end of the label 31 is connected to the printer 32. The printer 32 is used to print the label 31. The transmission mechanism 4 includes a telescopic cylinder assembly 41, a rotary cylinder 42, and a labeling member 43. One end of the telescopic cylinder assembly 41 is mounted on the frame 2, and the other end is connected to the rotary cylinder 42. The labeling member 43 is mounted on the rotary cylinder 42 and is used to attract the label 31 and apply it to the cigarette box 100. The detection assembly 5 is electrically connected to the conveying mechanism 1 and is used to detect the position of the cigarette box 100 and to open or close the conveying mechanism 1.

[0051] The conveying mechanism 1 is driven by a drive motor, a transmission belt or roller is connected to the drive end of the drive motor, and the cigarette box 100 is placed on the roller or transmission belt for conveyance. A frame 2 is placed next to the conveying mechanism 1, and the frame 2 is fixed to the ground with anchor bolts. The frame 2 is mounted with a supply assembly 3 and a transmission mechanism 4. The frame 2 has an outlet on the side close to the conveying mechanism 1, and a printer 32 is located at the outlet of the frame 2. A winding roller 33 is rotatably connected to the side wall of the frame 2, and an unused label 31 is wound around the winding roller 33. The label 31 is connected to the rotating shaft inside the printer 32. The printer 32 is used to print text, symbols, icons, etc. on the label 31. The telescopic cylinder assembly 41 is configured as a pneumatic slide cylinder and is fixedly mounted on the frame 2. The telescopic end of the telescopic cylinder assembly 41 is fixed to the bottom of the rotary cylinder 42 by screws. A labeling component 43 is fixed to the rotating table on top of the rotary cylinder 42. The labeling component 43 magnetically attracts the label 31 printed by the printer 32 and affixes the label 31 to the outer periphery of the cigarette box 100. The detection component 5 is used to detect whether the cigarette box 100 is in the first position and the second position on the conveying mechanism 1. When the cigarette box 100 is detected to be in the first position, the conveying mechanism 1 is controlled to close and the front of the cigarette box 100 is labeled. When the cigarette box 100 is in the second position, the conveying mechanism 1 is controlled to close again and the side of the cigarette box 100 is labeled.

[0052] The cigarette box labeling device operates as follows: First, the winding roller 33 feeds the label 31 into the printer 32, which prints the label 31. Then, the labeling component 43 absorbs the printed label 31. The cigarette box 100 is conveyed by the drive roller 12. When the detection assembly 5 detects that the cigarette box 100 is in the first position, it controls the conveying mechanism 1 to close, causing the cigarette box 100 to stop at the first position. The telescopic cylinder assembly 41 propels the rotating cylinder 42 and the labeling component 43 toward the conveying mechanism 1, gradually moving them toward the front of the cigarette box 100. Once they reach the front of the cigarette box 100, they remain stationary. Simultaneously, the rotating cylinder 42 activates and rotates, causing the labeling component 43 to rotate until the label 31 is parallel to the front of the cigarette box 100. The labeling component 43 then applies the absorbed label 31 to the front of the cigarette box 100. After labeling is complete, the conveying mechanism 1 activates again, and the cigarette box 100 continues to be conveyed. The telescopic cylinder assembly 41 retracts to its initial position. When the position sensor 51 detects that the cigarette box 100 is in the second position, the detection assembly 5 controls the conveying mechanism 1 to close again, causing the cigarette box 100 to stop in the second position. Next, the rotary cylinder 42 starts and rotates, causing the labeling member 43 to rotate until the label 31 and the conveying direction of the cigarette box 100 by the conveying mechanism 1 are parallel to each other. In other words, the labeling member 43 is parallel to the side of the cigarette box 100. Under the action of the telescopic cylinder assembly 41, the rotary cylinder 42 and the labeling member 43 are pushed in a direction gradually approaching the conveying mechanism 1 until the cigarette box 100 contacts the labeling member 43. The labeling member 43 then adheres the adsorbed label 31 to the side of the cigarette box 100, completing the side labeling. The labeled cigarette box 100 is then conveyed to the next process. Replacing the traditional connecting rod and spring labeling swing arm combination, a single labeling device is required to automatically label both the front and side of the cigarette box 100, taking up little space and reducing costs. Under the action of the detection assembly 5, the cigarette box 100 is labeled in two steps, front and side, respectively. Labeling is stable and orderly, ensuring labeling quality and efficiency. The cylinder, as the motion element, moves smoothly and with high positioning accuracy. This minimizes impact on the cigarette box 100 during labeling, preventing wrinkles. Its excellent stability ensures smooth movement during label removal, pressing, and return, effectively improving labeling quality.

[0053] Continue to refer to Figure 1-Figure 3The detection assembly 5 includes a position sensor 51 and a controller 52 electrically connected to the position sensor 51. The position sensor 51 is mounted on one side of the conveyor mechanism 1 and is used to detect whether the cigarette box 100 is in the first position or the second position on the drive roller 12. The controller 52 is used to control the drive motor to turn on or off. When the cigarette box 100 is in the first position, the front of the cigarette box 100 is labeled. When the cigarette box 100 is in the second position, the side of the cigarette box 100 is labeled. When the position sensor 51 detects that the cigarette box 100 is in the first position, the position sensor 51 sends a high level to the controller 52, which controls the drive motor to stop, thereby stopping the cigarette box 100 in the first position. When the position sensor 51 detects that the cigarette box 100 is in the second position, the position sensor 51 sends a high level to the controller 52, which controls the drive motor to stop, thereby stopping the cigarette box 100 in the second position.

[0054] Continue to refer to Figure 1-Figure 3 The telescopic cylinder assembly 41 includes a first telescopic drive member and a second telescopic drive member. The fixed end and telescopic end of the first telescopic drive member are connected to the frame 2 and the fixed end of the second telescopic drive member, respectively. The telescopic end of the second telescopic drive member is connected to the rotary cylinder 42. The first and second telescopic drive members are configured as pneumatic slide cylinders. The first telescopic drive member is fixed to the frame 2 via a swing arm bracket. The telescopic push end at the top of the first telescopic drive member is screwed to the fixed end of the second telescopic drive member. The telescopic push end at the top of the second telescopic drive member is screwed to the bottom of the rotary cylinder 42. The first telescopic drive member drives the second telescopic drive member, thereby moving the rotary cylinder 42 and the labeling member 43 toward or away from the conveying mechanism 1 relative to the frame 2. When the second telescopic drive member is activated, the rotary cylinder 42 and the labeling member 43 are moved closer to the conveying mechanism 1 relative to the first telescopic drive member to accommodate cigarette cases 100 of varying sizes, ensuring that the labeling member 43 can apply the labels 31 to the cigarette cases 100. Optionally, there are multiple telescopic cylinder groups 41, which are connected in sequence to increase the movement range of the labeling member 43, so that labels 31 can be applied to cigarette boxes 100 at different positions along the width direction of the conveying mechanism 1.

[0055] Continue to refer to Figure 1-Figure 3The transmission mechanism 4 also includes a third telescopic drive member 44, one end of which is connected to the rotary cylinder 42, and the other end of which is connected to the labeling member 43. Under the action of the telescopic cylinder assembly 41 and the rotary cylinder 42, the labeling member 43 can be driven to move to the front or side of the cigarette box 100 to apply the label 31. At the same time, under the action of the third telescopic drive member 44, the labeling member 43 is driven to compact the label 31 to prevent it from falling off. Then, under the action of the third telescopic drive member 44, the labeling member 43 is moved away from the cigarette box 100, facilitating the subsequent compaction of the label 31 in the cigarette box 100.

[0056] Continue to refer to Figure 1-Figure 3 The supply assembly 3 also includes a first conveyor roller 34, which is rotatably mounted on the frame 2 and connected to the label 31. One end of the label 31 is wound around the winding roller 33, and the other end is connected to the rotating shaft inside the printer 32. The middle of the label 31 abuts the first conveyor roller 34. The printer 32 prints on each label 31 one by one. The rotating shaft inside the printer 32 rotates to pull the label 31 off the winding roller 33. At the same time, the first conveyor roller 34 guides and tightens the label 31, ensuring that the label 31 does not wrinkle during entry into the printer 32, affecting the printing effect.

[0057] Continue to refer to Figure 1-Figure 3 The supply assembly 3 further includes a recycling roller 35, which is rotatably mounted on the frame 2 and connected to the release paper of the label 31. As the labeling component 43 successively absorbs the printed labels 31, the rotating shaft inside the printer 32 rotates, allowing the release paper of the label 31 to be ejected from the printer 32 and wound around the recycling roller 35, facilitating the recycling of the release paper, avoiding environmental pollution, and ensuring a clean environment and a clean floor.

[0058] Continue to refer to Figure 1-Figure 3 The supply assembly 3 also includes a second conveyor roller 36, which is rotatably mounted on the frame 2 and connected to the release paper. One end of the release paper is wrapped around the recovery roller 35, and the other end is connected to the rotating shaft of the printer 32. The middle of the release paper abuts the second conveyor roller 36. The second conveyor roller 36 guides and tightens the release paper, ensuring that it is smoothly and tightly wound around the recovery roller 35 for recycling, preventing the release paper from getting stuck on the recovery roller 35 and affecting recycling.

[0059] Continue to refer to Figure 1-Figure 3The conveying mechanism 1 includes a base 11, a drive roller 12, and a drive motor. The drive roller 12 is disposed on the base 11. The drive motor is mounted on the base 11, and the output end of the drive motor is connected to the drive roller 12. The drive roller 12 is used to convey the cigarette box 100. The drive motor is mounted on the base 11. The drive roller 12 includes a driving roller and multiple driven rollers. The driving roller and the multiple driven rollers are connected via a belt or chain drive. The output end of the drive motor is connected to the driving roller. Under the action of the drive motor, the driving roller rotates, and the driving roller drives the driven rollers to rotate, thereby conveying the cigarette box 100.

[0060] This embodiment also provides a cigarette box labeling method, such as Figure 4 As shown, through the implementation of the above-mentioned cigarette box labeling device, the cigarette box labeling method includes:

[0061] S100 : The labeling component 43 absorbs the label 31 .

[0062] The winding roller 33 feeds the label 31 into the printer 32 , and the printer 32 prints the label 31 . Then, the labeling member 43 absorbs the printed label 31 .

[0063] S200 : The conveying mechanism 1 conveys the cigarette box 100 .

[0064] S300: When the detection component 5 detects that the cigarette box 100 is in the first position, the conveying mechanism 1 is closed, and the front of the cigarette box 100 is labeled under the action of the transmission mechanism 4; when the detection component 5 detects that the cigarette box 100 is in the second position, the conveying mechanism 1 is closed again, and the side of the cigarette box 100 is labeled under the action of the transmission mechanism 4.

[0065] S300 is specifically:

[0066] S301: When the position sensor 51 detects that the cigarette box 100 is located at the first position, the controller 52 may control the conveying mechanism 1 to be closed.

[0067] The conveying mechanism 1 includes a base 11, a drive roller 12, and a drive motor. The drive roller 12 is mounted on the base 11, and the drive motor is installed on the base 11. The output end of the drive motor is connected to the drive roller 12. The drive roller 12 is used to convey the cigarette box 100. When the position sensor 51 detects that the cigarette box 100 is in the first position, the position sensor 51 sends a high level to the controller 52. The controller 52 controls the drive motor to stop, and the drive roller 12 stops rotating, thereby stopping the cigarette box 100 in the first position.

[0068] S302 : Under the action of the telescopic cylinder group 41 , the rotating cylinder 42 and the labeling component 43 move to the front of the cigarette box 100 . At the same time, the rotating cylinder 42 starts and rotates, so that the labeling component 43 attaches the adsorbed label 31 to the front of the cigarette box 100 .

[0069] The telescopic cylinder assembly 41 pushes the rotary cylinder 42 and labeling member 43 toward the conveyor mechanism 1, and they remain stationary when they reach the front of the cigarette case 100. Simultaneously, the rotary cylinder 42 activates and rotates, causing the labeling member 43 to rotate until the label 31 is parallel to the front of the cigarette case 100. The labeling member 43 then attaches the adsorbed label 31 to the front of the cigarette case 100, completing the front labeling.

[0070] S303: The telescopic cylinder assembly 41 retracts to the initial position.

[0071] S304 : The conveying mechanism 1 opens and continues to convey the cigarette box 100 .

[0072] S305: When the position sensor 51 detects that the cigarette box 100 is located at the second position, the controller 52 may control the conveying mechanism 1 to close again.

[0073] When the position sensor 51 detects that the cigarette box 100 is at the second position, the position sensor 51 sends a high level to the controller 52. The controller 52 can control the drive motor to stop again and the transmission roller 12 to stop rotating, so that the cigarette box 100 stops at the second position.

[0074] S306 : The rotating cylinder 42 is started and rotates. Under the action of the telescopic cylinder assembly 41 , the labeling member 43 sticks the adsorbed label 31 to the side of the cigarette box 100 .

[0075] The rotating cylinder 42 starts and rotates, causing the labeling member 43 to rotate until the label 31 and the conveying direction of the cigarette box 100 of the conveyor mechanism 1 are parallel to each other. In other words, the labeling member 43 is parallel to the side of the cigarette box 100. Under the action of the telescopic cylinder assembly 41, the rotating cylinder 42 and the labeling member 43 are pushed in a direction gradually approaching the conveyor mechanism 1 until the cigarette box 100 contacts the labeling member 43. The labeling member 43 then adheres the adsorbed label 31 to the side of the cigarette box 100, completing the side labeling. The labeled cigarette box 100 is then conveyed to the next process.

[0076] The cigarette box labeling method provided in this embodiment utilizes a cigarette box labeling device. Labeling components 43 absorb labels 31, and conveyor mechanism 1 conveys cigarette box 100. When detection component 5 detects that cigarette box 100 is in a first position, conveyor mechanism 1 is closed, and the front of cigarette box 100 is labeled under the action of transmission mechanism 4. When detection component 5 detects that cigarette box 100 is in a second position, conveyor mechanism 1 is closed again, and the side of cigarette box 100 is labeled under the action of transmission mechanism 4. Only a single labeling device is required to automatically label both the front and side of cigarette box 100, minimizing space and reducing costs. Under the action of detection component 5, cigarette box 100 is labeled on both the front and side in two steps, ensuring stable and orderly labeling, and ensuring both quality and efficiency.
