[0002] Firecrackers, also known as firecrackers, explosive firecrackers, etc., refer to products that explode when ignited and can produce effects such as popping sounds and flashes, and are mainly auditory effects. The original purpose of firecrackers was to drive away ghosts or welcome gods. Later, they developed into a symbol of the New Year with their strong festive color.

[0003] After firecrackers are produced, they need to be packaged. Common packaging is plastic sealing, box sealing or carton sealing. After packaging, labels with various specifications and parameters of the firecrackers need to be affixed to the surface of the packaging. The traditional method is that staff manually cut the labels and then stick them one by one. When labeling, it is necessary to frequently take and put the firecracker boxes, and it is inconvenient to automatically push the labels after labeling, so the labeling efficiency is low.

[0023] The labeling mechanism includes an electric slider 9, and the upper part of the base frame 1 is slidably connected to the electric slider 9, and a lower pressure rod 10 is fixedly connected to one side of the electric slider 9. The electric slider 9 is used to drive the lower pressure rod 10 to move up and down. A cutter 11 is slidably connected to the base frame 1, and the cutter 11 is located above the edge of the supporting plate 6. One side of the cutter 11 contacts the bottom of the lower pressure rod 10. The electric slider 9 drives the lower pressure rod 10 to move downward, thereby driving the cutter 11 to move downward. A reset spring 12 is provided between the cutter 11 and the base frame 1, and the reset spring 12 is used to drive the cutter 11 to reset. A pressing assembly is provided on the base frame 1.

[0024] The pressing assembly includes a clamping frame 13, which is slidably connected to the base frame 1, and is located above the conveyor belt 4. One side of the clamping frame 13 contacts the bottom of the lower pressure rod 10. The electric slider 9 drives the lower pressure rod 10 to move downward, thereby driving the clamping frame 13 to move downward. A reset spring 2 14 is provided between the clamping frame 13 and the base frame 1, and the reset spring 2 14 is used to drive the clamping frame 13 to reset.

[0025] The conveying mechanism includes a rack 15, and the rack 15 is fixedly connected to one side of the electric slider 9. An overrunning clutch 16 is fixedly connected to the active roller 2. The overrunning clutch 16 is used to drive the active roller 2 to rotate. A gear 17 is fixedly connected to the overrunning clutch 16, and the gear 17 is meshed with the rack 15. The rack 15 drives the overrunning clutch 16 to rotate through the gear 17, thereby driving the active roller 2 to rotate.

[0026] At the beginning, the staff inserts the label roll 8 on the label roller 5, passes one end of the label roll 8 between the two guide rollers 51, and places one end of the label roll 8 on the supporting plate 6, so that the side of the label roll 8 coated with adhesive faces downward, and then the staff places the firecracker boxes 7 on the conveyor belt 4 at even intervals, so that the rightmost firecracker box 7 is located below the cutter 11, and then a staff member starts the electric slider 9 to move downward, and the electric slider 9 moves downward to drive the lower pressure rod 10 to move downward, and the lower pressure rod 10 moves downward to drive the cutter 11 and the pressing frame 13 to move downward, and the reset spring 12 and the reset spring 2 14 are compressed. The downward movement of the cutter 11 will cut off a section of one end of the label roll 8. Under the action of gravity, the severed label will fall down onto the firecracker box 7, and the side of the label coated with adhesive will contact the top of the firecracker box 7. During the initial operation, the downward movement of the pressing frame 13 will not have any effect. During subsequent operation, the downward movement of the pressing frame 13 will contact the label on the firecracker box 7. The label on the firecracker box 7 is pressed tightly. Through the above operation, the firecracker box 7 can be labeled quickly, and the electric slider 9 moves downward to drive the rack 15 to move downward, and the rack 15 moves downward to drive the gear 17 to rotate. Under the action of the overrunning clutch 16, the active roller 2 will not rotate. After the label is affixed, the staff adjusts the electric slider 9 to move upward, and the electric slider 9 moves upward to drive the lower pressure rod 10 and the rack 15 to move upward. The lower pressure rod 10 moves upward and no longer squeezes the cutter 11 and the clamping frame 13. The reset spring 12 will rebound and drive the cutter 11 to move upward, the reset spring 2 14 will rebound and drive the clamping frame 13 to move upward, and the rack 15 moves upward to drive the gear 17 to rotate in the opposite direction. Under the action of the overrunning clutch 16, the active roller 2 will rotate, and the rotation of the active roller 2 drives the transmission belt 4 and the driven roller 3 to rotate. The rotation of the transmission belt 4 will drive the firecracker box 7 to move horizontally for a distance. Through the above operation, the firecracker box 7 can be transported after the label is affixed, thereby improving the labeling efficiency.

[0027] Embodiment 2: Based on embodiment 1, Figure 1-Figure 6As shown, it also includes a push roller 18, and two of the push rollers 18 are rotatably connected to the base frame 1. The two push rollers 18 are symmetrically arranged, and both of the two push rollers 18 are in contact with one end of the label roll 8. The push roller 18 is used to push the label roll 8, and a transmission component 19 is connected between one of the push rollers 18 and the active roller 2, and the active roller 2 drives one of the push rollers 18 to rotate through the transmission component 19. Gears 2 20 are fixed to the two push rollers 18, and the two gears 20 are meshed with each other. One of the push rollers 18 drives the other gear 2 20 to rotate through one of the gears 20, thereby driving the other push roller 18 to rotate.

[0028] The conveyor belt 4 is engraved with friction lines, and the friction lines on the conveyor belt 4 are used to increase the friction between the firecracker box 7 and the conveyor belt 4.

[0029] The active roller 2 rotates through the transmission assembly 19 to drive one of the push rollers 18 to rotate, the rotation of one of the push rollers 18 drives one of the gears 20 to rotate, the rotation of one of the gears 20 drives another gear 20 to rotate, and the rotation of the other gear 20 drives the other push roller 18 to rotate. Through the above operation, the label roll 8 can be automatically pushed after labeling is completed, thereby further improving the labeling efficiency.

[0030] The friction pattern on the conveyor belt 4 can increase the friction between the firecracker box 7 and the conveyor belt 4, thereby improving the stability of the firecracker box 7 when labeling.
