[0029] like Figure 1-10 As shown, during transportation, the cardboard is installed in the upper conveyor 3 at the front, the back side of the cardboard is inserted into the edge clamp 308 first, and the edge of the cardboard is aligned between each group of outer sliding frames 306 to keep it in close contact; Since different cardboards may have errors in size, the top screw 307 can be loosened to move the outer sliding frame 306 for adaptive adjustment and compensation; the driving motor 104 is controlled by a programmed program to drive the pulley 102 to rotate and continuously drive the toothed synchronous belt 2, and the toothed synchronous belt 2 continuously rotates to drive each group of conveyors 3 to move cyclically for cyclic conveying, and the start and stop of the conveying process and the conveying position are controlled by the program; during the movement of the conveyor 3, the trigger block 310 is used to trigger the proximity sensor 701 to assist in verifying the travel amplitude and ensure the stability of the feeding; The carrier frame 7 provides support for the auxiliary pulleys 302 on both sides of the top conveyor 3, and the rotating wheel support plate 105 provides support for the auxiliary pulleys 302 on both sides of the bottom conveyor 3, thereby reducing the load of the toothed synchronous belt 2; When the conveyor 3 moves to the front or rear, the auxiliary pulley 302 is separated from the rotating wheel support plate 105 or the carrier frame 7 and loses support. However, a counterweight frame 309 is provided at the bottom of the conveyor 3 to keep the conveyor 3 balanced.

[0030] Embodiment 2: On the basis of Example 1, after the conveyor 3 moves to the bottom of the creasing frame 4, the trimming groove 303 is vertically aligned with the trimmer 5, and then the first electric cylinder 401 is started to descend, driving the pressing plate 402 to descend, and the bottom surface of the pressing plate 402 is used to fit the paperboard, and the creasing strip 403 is embedded in the paperboard to produce the creasing; the size of the creasing strip 403 can be adjusted as needed; The edge trimmer 5 moves downward and penetrates into the edge trimming groove 303 to trim the edges of the paperboard; The first electric cylinder 401 is reset to complete the creasing and cutting steps; When the pressing plate 402 is raised, the demoulding pressing sheet 406 is automatically ejected by the spring to provide thrust for the paperboard to prevent the edge trimmer 5 from lifting the paperboard when it rises; The paper scraps and strips generated by the edge trimmer 5 when cutting the cardboard may be stuck in the edge trimmer 5. Therefore, when the first electric cylinder 401 contracts, the trigger plate 4022 contacts the trigger rod 407, squeezing the exhaust piston 4021, and discharging the air in the exhaust piston 4021 to the middle of the bottom of the edge trimmer 5, blowing out the stuck paper scraps and strips; accordingly, placing a tray below the cutting position can collect the paper scraps and strips that naturally fall when the edge trimmer 5 is cutting.

After all folding, the components are reset, and the paperboard is pulled out for manual assembly; The hem bend 802 will pass through the side push-through die 304 when working, while the center bend 804 will pass through the middle push-through die 304 when working; Since the middle of the carton needs to extend beyond one circle, there are convex strips on the cardboard for pasting, and this part can also be folded automatically.

[0032] Specific usage and function of this embodiment: In the present invention, when in use, the upper conveyor 3 moves from front to back to circulate; Install the cardboard in the upper conveyor 3 at the front, insert the back side of the cardboard into the edge clamp 308 first, and align the edge of the cardboard between each group of outer sliding frames 306 to keep it in close contact; The driving motor 104 is controlled by a programmed program to drive the pulley 102 to rotate and continuously drive the toothed synchronous belt 2. The toothed synchronous belt 2 continuously rotates, driving each group of conveyors 3 to move cyclically for cyclic conveying. The start and stop of the conveying process and the conveying position are controlled by the program. The carrier 7 provides support for the auxiliary pulleys 302 on both sides of the top conveyor 3, and the wheel support plate 105 provides support for the auxiliary pulleys 302 on both sides of the bottom conveyor 3, thereby reducing the load on the toothed synchronous belt 2; the conveyor 3 loses support when it moves to the front or rear side, but a counterweight frame 309 is provided at the bottom of the conveyor 3 to maintain the balance of the conveyor 3; during the movement of the conveyor 3, the trigger block 310 is used to trigger the proximity sensor 701 to assist in verifying the travel amplitude and ensure the stability of the feeding; The conveyor 3 is controlled to move to the bottom of the creasing frame 4, so that the trimming groove 303 is vertically aligned with the trimmer 5, and then the first electric cylinder 401 is started to descend, driving the pressing plate 402 to descend, and the bottom surface of the pressing plate 402 is used to fit the cardboard, and the creasing strip 403 is embedded in the cardboard to produce a creasing, and at the same time, the trimmer 5 penetrates the trimming groove 303 to cut the corners of the cardboard, and then the first electric cylinder 401 is reset to complete the creasing and cutting steps; when the pressing plate 402 rises, the demoulding sheet 406 is automatically ejected by the spring to provide thrust for the cardboard to prevent the cardboard from being lifted up when the trimmer 5 rises; repeat this step for processing; At the same time, the cardboard that has been indented is moved to the bottom of the folding frame 6, the second electric cylinder 601 is extended to press the positioning pressure plate 602 on the top of the cardboard, and then the third electric cylinder 801 is extended to use the folding corner 802 to fold the cardboard, and the fourth electric cylinder 803 is extended to push the folding corner 804 to fold the folded surface according to the indentation. After all folded, the components are reset, the cardboard is pulled out and manually assembled.
