[0002] When assembling cartons, it is necessary to apply glue to the edges of the cartons before pasting and splicing them to achieve bonding and reinforcement of the cartons. In the prior art, there is a special machine for gluing cartons. The carton gluing machine is provided with a lifting glue dispensing mechanism and a glue supply mechanism. When in use, it is necessary to adjust the gluing frequency, stack the cartons, and make the gluing position located below the glue dispensing mechanism. Through each gluing action, a carton is pulled out and glued and folded.

[0003] When the automatic carton gluing device in the prior art is used, the speed of extracting the carton needs to be consistent with the gluing frequency of the gluing mechanism. If there is a large deviation, it will lead to missed gluing or repeated gluing. For cartons of different volumes and types, the folding and splicing speeds of the cartons are different. In order to make the gluing frequency consistent with the extraction and folding speed of the carton, the frequency of the gluing mechanism needs to be adjusted, which is cumbersome and inconvenient.

The front surface of the side column 3 is fixedly connected with a column guide rod 301 by screws, and the front surface of the side column 3 located on the right is connected with a linkage static rack 302 by welding; the rear ends of the follow-up lifting platform 4 are fixedly connected with a balancing slider 401, and the balancing slider 401 is slidably connected to the column guide rod 301, which plays a guiding role and supports the straight lifting movement of the follow-up lifting platform 4.

[0031] In the disclosed embodiment, the right end of the linkage shaft 6 is fixedly connected with a linkage gear column 601, which is meshed with the linkage static rack 302 to form a gear rack transmission. The outer surface of the left half of the linkage shaft 6 is milled with a glue pushing screw 602, and the outer surface of the glue injection piston 8 is tightly fitted with the inner wall of the automatic glue discharge cylinder 7. A piston spiral push hole 801 is opened through the center of the glue injection piston 8, and the piston spiral push hole 801 is spirally connected to the glue pushing screw 602; when the follow-up lifting platform 4 moves up and down, the linkage gear column 601 is driven to roll on the linkage static rack 302, driving the linkage shaft 6 to rotate, and the glue injection piston 8 is controlled to slide inside the automatic glue discharge cylinder 7 through the spiral transmission of the glue pushing screw 602 and the piston spiral push hole 801, so as to push the glue liquid inside the automatic glue discharge cylinder 7.

[0032] In the disclosed embodiment, a glue injection tube 701 is fixedly connected to the left end face of the automatic glue discharging cylinder 7. The glue injection tube 701 is a tube body of a "T"-shaped structure. The front section of the glue injection tube 701 is located directly behind the glue coating roller 5. A glue injection check valve 702 is installed on the glue injection tube 701. The inlet of the glue injection check valve 702 faces the automatic glue discharging cylinder 7.

[0033] Embodiment 2, on the basis of embodiment 1, a glue inlet pipe 704 is fixedly connected to the left end face of the automatic glue discharging cylinder 7, and the glue inlet pipe 704 is a hose. A glue inlet check valve 705 is fixedly connected to the glue inlet pipe 704, and the outlet of the glue inlet check valve 705 faces the automatic glue discharging cylinder 7, and the outer end of the glue inlet pipe 704 is located inside the glue storage container 2; when a single use is completed, when the cartons are stacked again, the follow-up lifting platform 4 is lifted until it is flush with the upper surface of the cartons.

[0034] The working principle of this embodiment is as follows: first, the cartons that have not been glued and folded are stacked and moved to the front of the gluing device so that the gluing area is directly below the gluing roller 5. The gluing roller 5 is pressed against the gluing area of ​​the carton by the gravity of the follow-up lifting platform 4, the gluing roller 5, the linkage swivel 6, and the automatic glue outlet roller 7. Then the staff takes the carton for folding and pulls the top carton forward to roll the gluing roller 5 in the gluing area so that the glue on the outer surface of the gluing roller 5 is smeared on the gluing area. After the top carton is pulled out, the follow-up lifting platform 4, the gluing roller 5, the linkage swivel 6, and the automatic glue outlet roller 7 move downward under the action of gravity, so that the gluing roller 5 contacts the gluing area of ​​the carton on the top layer again. At the same time, as the follow-up lifting platform 4 moves downward, the linkage gear column 601 rolls downward on the linkage static rack 302, driving the linkage swivel 6 and the glue pushing wire The lever 602 rotates, and the glue pushing screw 602 and the piston spiral pushing hole 801 form a spiral transmission, pushing the glue injection piston 8 to move in the direction away from the opening of the automatic glue discharging cylinder 7, squeezing the glue inside the automatic glue discharging cylinder 7, allowing the glue to enter the glue injection tube 701 and adhere to the glue coating roller 5 through the glue injection hole 703, continuously supplying glue to the glue coating roller 5. When a single use is completed, when the cartons are stacked again, the follow-up lifting platform 4 is lifted until it is flush with the upper surface of the carton. In this process, the linkage rotating shaft 6 rotates under the gear rack transmission of the linkage gear column 601 and the linkage static rack 302, driving the glue injection piston 8 to move in the direction of the opening of the automatic glue discharging cylinder 7, the glue injection check valve 702 is automatically closed, and the glue inlet check valve 705 is automatically opened, and the glue inside the glue storage container 2 is sucked into the automatic glue discharging cylinder 7 for storage, thereby realizing automatic gluing.
