When the photoelectric detectors 29 detect that the cigarette pack 76 is being conveyed to the second cigarette pack conveying area 5, the photoelectric detectors 29 send a signal to the control module 1, so that the control module 1 controls the first servo motor 8 of the first cigarette pack conveying area 4 to stop moving, thereby ensuring that the cigarette packs in the first cigarette pack conveying area 4 stop being conveyed. Figure 19 The third servo motor 32 is mounted on the side of the third support rod 27 of the second lower belt 69 by eight sets of M5 hexagon socket screws.

[0064] like Figure 7 As shown, the bearing seat 31 and the third servo motor 32 of the steel stamp replenishing module 6 are installed and positioned on the side of the third support rod 27 of the second lower belt 69.

[0066] Specifically, if Figure 18 As shown, the working principle of the V-belt power mechanism 7 that provides power for the first cigarette pack conveying area 4 is that the first servo motor 8 rotates to drive the second V-belt pulley 9 and drives the upper pulley to rotate through the second V-belt 10, and the rotation of the second V-belt pulley 9 drives the fifth transmission shaft 11 corresponding to the first lower belt 19 to rotate, thereby driving the third flat belt 12 of the first lower belt 19 to move, and driving the sixth transmission shaft 13 of the first lower belt 19 to rotate, and then driving the first V-belt pulley 14 below the V-belt transmission mechanism 23 to rotate, and driving the first V-belt pulley 14 on the upper layer of the V-belt transmission mechanism 23 to rotate through the first V-belt 15, and transferring kinetic energy to the third transmission shaft 16 of the first upper belt 18, thereby driving the second flat belt 59 of the first upper belt 18 to move, and achieving speed matching between the first lower belt 19 and the first upper belt 18 of the first cigarette pack conveying area 4 during movement through two sets of V-belt transmission mechanisms 23.

[0067] Furthermore, if Figure 18As shown, the working principle of the V-belt power mechanism 7 that provides power for the second cigarette pack conveying area 5 is as follows: the first servo motor 8 rotates to drive the second V-belt pulley 9 and drives the upper pulley to rotate through the second V-belt 10, and the rotation of the second V-belt pulley 9 drives the eighth transmission shaft 20 corresponding to the second lower belt 69 to rotate, thereby driving the fourth flat belt 21 corresponding to the second lower belt 69 to move, and drives the seventh transmission shaft 22 corresponding to the second lower belt 69 to rotate, and then drives Figure 15 The first V-belt pulley 14 shown rotates, and the upper first V-belt pulley 14 is driven to rotate through the first V-belt 15, and the kinetic energy is transferred to the first transmission shaft 25 corresponding to the second upper belt 26, thereby driving the first flat belt 77 of the second upper belt 26 to move, and the speed matching of the second lower belt 69 corresponding to the second cigarette pack conveying area 5 and the second upper belt 26 during movement is achieved through two sets of V-belt transmission mechanisms 23.

[0069] Furthermore, the automatic replenishment device for the steel stamp of the hard-box cigarette package also includes a control processing center (not shown), which is communicatively connected with the control module 1, the first servo motor 8, the second servo motor 40, the third servo motor 32, the photoelectric detector 29, the high-definition motion camera 44 and other components to process the photoelectric signals and images through the control processing center, and control the opening / closing and forward / reverse rotation of each servo motor, and perform image graying, enhancement, pooling, sharpening and other processing on the image signal collected by the high-definition motion camera 44 to obtain the processed image, and then compare the steel stamp position to control the telescopic cylinder 42 to extend and retract so that the steel stamp 43 is pressed onto the cigarette package 76. After the control module 1 is electrically connected to the control processing center, the operator can adjust the device to automatic operation and manual operation, wherein the manual mode can only be started when the host is stopped to prevent the operator from making a mistake in adjusting the device when the host is running and causing damage to the device; Figure 3 As shown, in manual mode, the operator can rotate the module to select either the stamping module or the conveying module. Selecting the stamping module allows the operator to choose between the vertical, vertical, and telescopic modes below. Selecting the conveying module allows the operator to choose between 1 and 2, with 1 representing the movement of the first cigarette pack conveying area 4 and 2 representing the movement of the second cigarette pack conveying area 5. After selecting a module, the operator can select the movement rate: x1, x2, x3, x4, or x5. After selecting, rotate the fine-tuning dial to adjust the movement of the device. Using the control panel, the operator can control the rotation and movement of the device, making operation more convenient.

[0070] During operation, after starting the power supply, the operator places the cigarette packs 76 with the supplementary stamps in the cigarette pack warehouse 60 in turn, and conveys the cigarette packs 76 to the second cigarette pack conveying area 5 through the belt of the first cigarette pack conveying area 4. After the cigarette packs 76 arrive at the second cigarette pack conveying area 5, the photoelectric detector 29 detects the cigarette packs 76, and controls the belt of the first cigarette pack conveying area 4 to stop running. The cigarette packs 76 continue to be conveyed from the second cigarette pack conveying area 5 to the stamp replenishment module 6. After the high-definition motion camera 44 captures the arrival of the cigarette packs 76 at the designated position, the belt of the second cigarette pack conveying area 5 stops running, and the stamp replenishment module 6 starts running. The stamp replenishment position is captured by the camera of the high-definition motion camera 44, and the telescopic cylinder 42 is controlled to reach the appropriate position to press the stamp. After the cigarette packs 76 are replenished with the stamps, a signal is given to control the belts of the second cigarette pack conveying area 5 and the belt of the first cigarette pack conveying area 4 to restart running, and the cigarette packs 76 with the replenished stamps are discharged from the equipment in turn.

[0071] The automatic steel stamp replenishing device for hard-box cigarette packs provided by the embodiment of the present invention transports cigarette packs through the first cigarette pack conveying area and the second cigarette pack conveying area, and automatically replenishes steel stamps through the steel stamp replenishing module. The operator only needs to install the cigarette packs to be stamped into the cigarette pack warehouse, and there is no need to scrap the defective cigarette packs lacking steel stamps or manually press the steel stamps, which improves the operator's work efficiency and avoids waste. It has a simple structure, low cost, and does not require cumbersome design; the operation panel of the control module can be turned to automatic mode, and the operation is simple; the cigarette pack conveying module uses upper and lower belts for transportation to ensure the stability of the cigarette pack conveying; the steel stamp pressing module uses a high-definition camera to capture the missing position of the steel stamp and automatically presses it, which improves the operating stability of the device.
