[0002] Cardboard box packaging is widely used in logistics, e-commerce, and manufacturing. Traditional cardboard box sealing relies mainly on manual folding, pressing, and tape application, which is inefficient, labor-intensive, and produces inconsistent sealing quality. While automatic folding and sealing machines are now available, they still present several problems:

[0003] Some tapes may not adhere completely, which can cause the box to open during transportation. When the surrounding environment is humid, the moisture content on the surface of the box increases, which can easily cause the tape to detach. Utility Model Content

[0026] The detection mechanism 6 includes a first drive cylinder 61, a horizontal plate 62, a humidity sensor 63, a second drive cylinder 64, a baffle 65, and a control box 66.

[0027] The first upright 5 is connected to an extension plate, and the first driving cylinder 61 is located above the extension plate; the connecting rod of the first driving cylinder 61 is connected to the horizontal plate 62; the humidity sensor 63 is located below the horizontal plate 62; the second driving cylinder 64 is located at the bottom of the bracket 1; the connecting rod of the second driving cylinder 64 is connected to the baffle 65; the control box 66 is also located at the bottom of the bracket 1.

[0028] The humidity sensor 63, the second drive cylinder 64, and the control box 66 are electrically connected.

[0029] The sliding assembly 8 includes a slide groove 81, a screw 82, and a second rotating motor 83;

[0030] The second upright 7 has a sliding groove 81 inside; a screw 82 is rotatably installed inside one of the sliding grooves 81; a second rotating motor 83 is provided at the top of the sliding groove 81; the output end of the second rotating motor 83 is connected to the screw 82; a moving block is threadedly connected to the screw 82, and the moving block is fixedly connected to one side of the moving plate 9; another second upright 7 has a matching sliding rod inside, and the other side of the moving plate 9 is slidably connected to the sliding rod.

[0032] Working principle: First, the carton is placed above the conveyor belt 3. Then, the first drive cylinder 61 is opened, causing the connecting rod of the first drive cylinder 61 to drive the horizontal plate 62 to push out. Then, the humidity sensor 63 below the horizontal plate 62 detects the carton conveyed above the conveyor belt 3. When the humidity sensor 63 detects that the moisture content on the surface of the carton is too high, the second drive cylinder 64 drives the baffle 65 to block the carton. Then, the carton is removed manually to dry. The subsequent cartons are then fed onto the feeding roller 4 for conveying.

[0033] During the feeding process of the carton by the feeding roller 4, the third drive cylinder 19 is activated, causing the cylinder's connecting rod to drive the clamping plate 20 to stably fix the side of the carton. At this time, the first rotary motor 13 is activated, causing the rotating plate 12 of the first rotary motor 13 to rotate. Then, the adhesive roller 14 on the rotating plate 12 applies adhesive to the surface of the carton. Finally, the electric push rod 15 is activated, causing the pressure roller 17 to stably press the adhesive tape on the surface of the carton. Content not described in detail in this specification belongs to prior art known to those skilled in the art.
