[0036] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0037] As shown in the figure, a cigarette cartridge tube product code anti-counterfeiting marking production line includes a flow channel 9, which is composed of parallel guide strips, and the flow channel 9 guides the carrier 8. The guide strips are fixed by adjustable positioning pins 11, and the width of the flow channel 9 can be adjusted by adjusting the positioning pins 11.

[0038] The flow channel 9 is divided into a feeding section, a marking section and a discharging section in sequence. A buffer conveyor belt 2 is arranged below the flow channel of the feeding section and the flow channel of the discharging section. A group of laser marking machines are symmetrically arranged on both sides of the flow channel 4 of the marking section. The flow channel 4 of the marking section is suspended by a cushion seat 16.

[0039] A material distribution mechanism 3 is provided at the outlet of the feed section flow channel, and the material distribution mechanism 3 is used to determine whether the current carrier 8 enters the marking section. The material distribution mechanism 3 includes a blocking cylinder 10 and a material shortage detection probe 12, and the material shortage detection probe 12 is closer to the outlet of the feed section flow channel than the blocking cylinder 10. The blocking cylinder 10 is used to press the carrier 8 against the feed section flow channel, and the material shortage detection probe 12 is used to determine whether a carrier 8 stays at the outlet of the feed section flow channel. The distance between the blocking cylinder 10 and the material shortage detection probe 12 is greater than one times the length of the carrier 8, and less than two times the length of the carrier 8, so as to facilitate the judgment of the carrier 8 and prevent repeated detection.

[0040] A feeding roller 13 is provided at the feed port of the marking section flow channel 4, and the feeding roller 13 is driven by a stepper motor. The stepper motor controls the feeding and material distribution by rotating the angle. The stepper motor rotates a specified number of times to feed the current carrier 8 into the marking section flow channel 4, and then stays for a period of time. During the stepper motor's stay, the next section of the carrier 8 is stuck at the entrance of the marking section flow channel 4, thereby blocking all subsequent carriers 8.

[0041] A positioning mechanism is provided in the middle of the marking section flow channel 4, and the positioning mechanism is used to precisely position the carrier 8. The positioning mechanism includes a clamping cylinder 14 and a positioning cylinder 15, and the positioning cylinder 15 is closer to the discharge port of the marking section flow channel 4 than the clamping cylinder 14. The clamping cylinder 14 is used to press the carrier 8 against the marking section flow channel 4, and the positioning cylinder 15 is used to intercept and precisely position the carrier 8 of the marking section flow channel 4.

[0042] A conveying mechanism is provided below the flow channel 4 of the marking section, and the conveying mechanism is used to transport the carrier 8 to the positioning mechanism. The conveying mechanism includes a linear module 21 and a lifting mechanism, and the lifting mechanism reciprocates along the length direction of the linear module 21. The linear module 21 includes a servo motor 19 and a threaded rod, and the threaded rod is fixed on the output shaft of the servo motor 19, and a slide is threadedly connected to the threaded rod. The lifting mechanism includes a lifting cylinder 17 and a U-shaped clamp 18, and the bottom of the lifting cylinder 17 is fixed on the slide. The middle part of the bottom end of the clamp 18 is fixed on the lifting cylinder 17, and the clamp 18 after lifting is clamped at both ends of the carrier 8. After the clamp 18 clamps the carrier 8, the slide moves forward to send the carrier 8 to the positioning mechanism, and the positioning cylinder 15 of the positioning mechanism intercepts the carrier 8.

[0043] A visual inspection mechanism 5 is also provided at the end of the marking section flow channel 4, and the visual inspection mechanism 5 is used to detect whether the cigarette bomb tube 20 has completed marking.

[0044] In order to prevent the carrier 8 in the flow channel of the discharge section from falling out of the flow channel 9, an intercepting cross bar is provided at the end of the flow channel of the discharge section.

[0045] A return conveyor belt 1 is provided below the flow channel 9. The return conveyor belt 1 is located below the buffer conveyor belt. Both ends of the return conveyor belt 1 exceed the buffer conveyor belt 2. The return conveyor belt 1 and the buffer conveyor belt 2 run in opposite directions. After the marking is completed, the carrier 8 is unloaded from the cigarette cartridge tube 20 and placed in the return conveyor belt 1, and is guided to the starting position to wait for the next filling. The buffer conveyor belt 2 and the return conveyor belt 1 are driven by the drive motor 6 respectively.

[0046] In order to facilitate the operation of the above device, the present application also proposes a method for anti-counterfeiting marking of a product code of a cigarette cartridge tube, comprising the following steps:

[0047] S1: The carrier 8 is filled and then placed on the buffer conveyor belt 2 of the feed section flow channel;

[0048] S2: The carrier 8 enters the dividing mechanism 3 of the feed section flow channel 9, and the material shortage detection probe 12 of the dividing mechanism 3 detects whether there is a carrier 8 staying at the end of the feed section flow channel. When there is no carrier 8 staying, the current carrier 8 smoothly enters the marking section flow channel 4; when there is a carrier 8 staying, the blocking cylinder 10 of the dividing mechanism 3 is started, and the next section of the carrier 8 is pressed against the flow channel 9;

[0049] S3: After the carrier 8 enters the marking section flow channel 4, the feeding roller 13 at the entrance end of the marking section flow channel 4 is started to feed the carrier 8 into the marking section flow channel 4; at the same time, the next section of the carrier 8 is stuck at the entrance of the marking section flow channel 4, that is, the next section of the carrier 8 stays in the flow channel 9 between the lack of material detection probe 12 and the feeding roller 13.

[0050] S4: After the carrier 8 passes through the feeding roller 13, the conveying mechanism under the marking section flow channel 94 is started; the lifting mechanism of the conveying mechanism lifts up the clamp 18, and the two ends of the clamp 18 are clamped on the two ends of the carrier 8; the linear module 21 of the conveying mechanism transports the current carrier 8 to the positioning mechanism, and then the conveying mechanism returns to the origin and waits for the next conveying instruction;

[0051] S5: The positioning cylinder 15 of the positioning mechanism intercepts the carrier 8, and then the clamping cylinder 14 presses the carrier 8 against the flow channel 9, thereby completing the precise positioning operation of the carrier 8, and then waiting for the marking to be completed;

[0052] S6: After the carrier 8 is pressed against the carrier 8, multiple laser marking heads of the laser marking machine simultaneously mark the outer wall and inner wall of the cigarette cartridge tube 20 on the carrier 8; the outer wall of the cigarette cartridge tube 20 is engraved with an anti-counterfeiting code, and the inner wall of the cigarette cartridge tube 20 is engraved with an anti-counterfeiting digital code;

[0053] S7: After marking is completed, the positioning mechanism releases the carrier 8 and waits for the next carrier 8 to enter; when the next carrier 8 enters, the current carrier 8 is squeezed out of the positioning mechanism;

[0054] S8: The carrier 8 of the extrusion positioning mechanism continues to move forward and gradually enters the discharge section flow channel 9, waiting for the cigarette cartridge tube 20 to be sorted;

[0055] S9: The sorted carrier 8 is put back into the return conveyor belt 1, and is transferred by the return conveyor belt 1 to the bottom of the feed section flow channel 9, waiting for the next round of cigarette cartridge tubes 20 to be filled.

[0056] In summary, the present invention adopts the cigarette cartridge tube product code anti-counterfeiting marking production line and processing method of the above structure, which has high marking efficiency and good marking effect.

[0057] The above are specific embodiments of the present invention, but the protection scope of the present invention should not be limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention, so the protection scope of the present invention should be based on the protection scope defined in the claims.
