[0046] In this embodiment, the front and rear ends of the side conveying frame 43 are respectively rotatably connected with second rotating wheels 431, and the two second rotating wheels 431 are rotatably connected to the side conveyor belt 44, wherein second adjustment grooves 432 are respectively opened on the left and right sides of the front end of the side conveying frame 43, and a third drive motor 433 is provided at the rear end of the side conveying frame 43, and the third drive motor 433 is connected to the second rotating wheel 431 at the rear end; the second adjustment groove 432 extends along the length of the side conveying frame 43, and the two second adjustment grooves 432 are commonly slidably connected with a second adjusting shaft 434, and the second adjusting shaft 434 is slidably connected to the second rotating wheel 431 at the front end, and a second adjusting screw 435 is threadedly connected to the side conveying frame 43, and the second adjusting screw 435 is rotatably connected to the second adjusting shaft 434.

[0047] In this embodiment, the specific sealing process is as follows: when it is necessary to seal a carton of a conventional shape, such as a rectangular structure, the side pressure wheel 254 is swung to a vertical direction in advance, so that the first limiting hole 2221 is aligned with the second limiting hole 2411, and then the latch 2222 passes through the first limiting hole 2221 and the second limiting hole 2411 in sequence to limit the side pressure wheel 254 to a vertical direction, wherein the side of the carton to be sealed has been smeared with glue in advance; At the same time, the positions of the side conveyor belt 44 and the upper conveyor belt 37 are adjusted according to the width and thickness specifications of the carton, and the first servo motor 32, the second servo motor 393, and the third servo motor 42 are started respectively. The second servo motor 393 drives the second screw 394 to rotate, so as to drive the first sliding seat 392 and the crossbeam 31 to translate left and right until they move to the set position, and then the first servo motor 32 drives the first transmission shaft 321 to rotate, so as to drive the two second driving gears 322 to rotate, and the second driving gear 322 drives the second driven gear 311 to rotate through the second chain 323, thereby driving the first lifting frame 331 and the upper conveyor frame 36 to move up and down, until the upper conveyor frame 36 and the upper conveyor belt 37 move to the set position, so as to adapt to different thickness specifications of the carton; the third servo motor 42 drives the third screw 421 to rotate, so as to drive the second sliding seat 411 and the side conveyor frame 43 to translate left and right, until the side conveyor frame 43 and the side conveyor belt 44 translate to the set position, so as to adapt to different width specifications of the carton.

[0048] At this time, the carton to be sealed is placed on the multiple conveying rollers 11, so that the left side of the carton to be sealed is aligned with the side sealing mechanism, and the right side of the carton to be completely sealed is aligned with the side conveyor belt 44, and then the first driving motor 12 is started, the first driving motor 12 drives the first driving gear 121 to rotate, and the first driving gear 121 drives the multiple first driven gears 111 to rotate through the first chain, so as to drive the multiple conveying rollers 111 to rotate synchronously to realize the conveying of the carton. When the end of the carton contacts the upper conveyor belt 37, the first lifting cylinders 3 are respectively started. 5. The second drive motor 363, the third drive motor 433, and the piston rod of the first lifting cylinder 35 are extended to drive the second lifting frame 341 and the upper conveyor belt 37 to move downward until the upper conveyor belt 37 presses down the top of the carton. The second drive motor 363 drives the upper conveyor belt 37 to convey, and the third drive motor 433 drives the side conveyor belt 44 to convey. The side conveyor belt 44 fits the right side of the carton. In this way, the upper conveyor belt 37 rolls and conveys the top of the carton, and the side conveyor belt 44 rolls and conveys the right side of the carton, thereby realizing the compression of the carton for transportation.

[0049] The above structure presses the carton for conveyance, wherein when the carton passes through the side sealing mechanism, the pre-tilted and folded downward cardboard on the carton rolls and contacts the multiple side pressure wheels 254, and then the multiple first translation cylinders 21 are started, and the piston rods of the first translation cylinders 21 are extended to push the first translation seat 211, the first translation frame 221, the mounting seat 24, and the multiple side pressure wheels 254 to translate close to the left side of the carton (the side of the carton has been pre-coated with glue), so that the multiple side pressure wheels 254 push the cardboard to fold downward and close to the left side of the carton until the cardboard is vertically attached to the left side of the carton, thereby realizing automatic side sealing during the carton conveying process.

[0050] When it is necessary to seal a carton with irregular or special-shaped structure, the latch 2222 is pulled out to make the latch 2222 withdraw from the first limiting hole 2221 and the second limiting hole 2411. At this time, under the action of the rotating shaft 241 and the buffer unit, the mounting seat 24 and the plurality of side pressing wheels 254 swing along the axis of the carton conveying direction, so that the plurality of side pressing wheels 254 are closely attached to the side of the carton with special-shaped structure, so that the cardboard can be pressed against the side of the carton to achieve sealing; Among them, when the mounting seat 24 and multiple side pressure wheels 254 swing clockwise, the second spring 233 on the left is stretched and the telescopic rod 232 on the left is extended, while the second spring 233 on the right is compressed and the telescopic rod 232 on the left is contracted; when the mounting seat 24 and multiple side pressure wheels 254 swing counterclockwise, the second spring 233 on the left is compressed and the telescopic rod 232 on the left is contracted, while the second spring 233 on the right is stretched and the telescopic rod 232 on the left is extended; the setting of the counterweight block 255, when the mounting seat 24 and multiple side pressure wheels 254 swing, is affected by the gravity of one side of the side pressure wheel 254, and the counterweight block 255 can ensure gravity balance, thereby preventing the mounting seat 24 and multiple side pressure wheels 254 from tipping toward the side of the side pressure wheel 254 when they are stationary.

[0051] When the side pressure wheel 254 contacts the cardboard, the first slide bar 251 moves the side pressure wheel 254 to the left rear side. At this time, the first spring 252 stretches, pulling the first slide bar 251 and the side pressure wheel 254 to move in the opposite direction, playing a buffering role.
