[0034] A plurality of folding plates 6 are fixedly mounted on the lower mounting frame 203 for folding the folded edge 101 of the carton blank 1 so as to fold the carton blank 1 into a carton shape;

[0035] The control box 202 is provided with a punching mechanism for pressing the paper box blank 1 on the guide plate 205 into the forming space surrounded by a plurality of folding plates 6;

[0036] The lower mounting frame 203 is provided with a bonding mechanism 7 for bonding and fixing the four folded corners of the paper box blank 1 folded into a paper box shape.

[0037] The carton blank 1 is conveyed to the guide plate 205 by the provided blank conveyor belt 1001, and then the carton blank 1 on the guide plate 205 is punched into a forming space surrounded by a plurality of folding plates 6 by a punching mechanism, so that the four folded edges 101 of the carton blank 1 are folded upward, and the carton blank 1 is folded into the shape of a carton, and then the four corners of the formed carton are bonded and fixed by the bonding mechanism 7.

[0038] In this embodiment, in order to allow the paper box blank 1 to be folded smoothly, the upper end of the folding plate 6 is arranged in an arc shape. In order to prevent the formed paper box from falling directly from the forming space, the forming space surrounded by a plurality of folding plates 6 and the paper box blank 1 folded into a paper box shape are interference fit.

[0039] In this embodiment, the stamping mechanism includes a first electric push rod 4, which is fixedly installed on one side of the control box 202. A pressure block 5 is fixedly installed at the bottom of the piston rod of the first electric push rod 4. By controlling the extension of the piston rod of the first electric push rod 4, the pressure block 5 can be driven to move downward, and the pressure block 5 drives the paper box blank 1 to move into the molding space.

[0040] Specifically, in this embodiment, four groups of bonding mechanisms 7 are provided, and the four groups of bonding mechanisms 7 correspond to the four corner positions of the paper box blank 1 respectively. The four bonding mechanisms 7 all include a mounting plate 701, and the mounting plate 701 is fixedly mounted on the lower mounting frame 203. A support frame 702 and an assembly seat 709 are fixedly mounted on the top of the mounting plate 701. A discharge tray 703 for releasing the adhesive tape 704 is rotatably mounted on the upper end of the support frame 702. A slide rail is fixedly mounted on the top of the assembly seat 709, and a slider 710 is slidably mounted on the slide rail. A tensioning frame 705 is fixedly mounted on one end of the slider 710. The tensioning frame 705 A tensioning roller 706 is rotatably installed on the top, a motor 708 is fixedly installed on the bottom of the lower mounting frame 203, a waste tape collecting roller 707 is fixedly installed on the rotating shaft of the motor 708, and the end of the tape 704 away from the discharge tray 703 passes through the tensioning frame 705 and is wound around the waste tape collecting roller 707, a third electric push rod 712 is fixedly installed on the slider 710, an angle iron pressing cutter head 713 is fixedly installed on the piston rod end of the third electric push rod 712, a second electric push rod 711 is fixedly installed on the assembly seat 709, and the piston rod of the second electric push rod 711 is fixedly connected to one side of the slider 710.

[0041] When the bonding mechanism 7 is in use, after the paper box blank 1 is folded into the paper box state, the piston rod of the second electric push rod 711 is extended, so that the tape 704 is attached to the folded corner of the formed paper box, and then the piston rod of the third electric push rod 712 is controlled to extend, thereby shearing the tape 704. The sheared tape 704 is tightly pressed against the folded corner of the formed paper box by the angle iron pressing knife head 713, thereby completing the bonding and fixing of the folded corner of the paper box. At this time, the piston rod of the third electric push rod 712 is retracted, and then the piston rod of the second electric push rod 711 is controlled to retract, thereby driving the tape 704 to reset, and then the motor 708 drives the waste tape collection roller 707 to rotate, and the cut tape 704 is reeled up to facilitate the next bonding operation.

[0042] Specifically, in order to ensure that the carton blank 1 can be accurately located above the molding space after entering the material guide plate 205 , a stopper 206 for positioning the conveying position of the carton blank 1 is fixedly mounted on the material guide plate 205 .

[0043] In this embodiment, a controller 3 is fixedly installed on the control box 202, and the first electric push rod 4, the second electric push rod 711, the third electric push rod 712, the motor 708 and the drive motor are all controlled by the controller 3. A proximity sensor 8 for detecting the paper box blank 1 on the guide plate 205 is fixedly installed at the bottom of the control box 202. The proximity sensor 8 is electrically connected to the signal input end of the controller 3. In this embodiment, the proximity sensor 8 adopts an Omron proximity sensor with model E2B-M12KN08-M1-B1, and the controller 3 adopts a Siemens s7-400 series PLC controller to achieve automatic operation.

[0044] In this embodiment, a finished product conveyor belt 9 is also included. The finished product conveyor belt 9 is arranged directly below the forming space surrounded by a plurality of folding plates 6. The finished product conveyor belt 9 can collect and convey the assembled paper boxes in a centralized manner.

[0045] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0046] Working principle: when in use, put the carton blank 1 on the blank conveyor belt 1001, and then start the driving motor to convey the carton blank 1 on the blank conveyor belt 1001 to the guide plate 205. When the proximity sensor 8 detects the carton blank 1, the proximity sensor 8 transmits a signal to the controller 3. The controller 3 controls the piston rod of the first electric push rod 4 to extend, thereby driving the pressure block 5 to move downward, so that the pressure block 5 drives the carton blank 1 to move into the forming space. After moving into the forming space, the four folding edges 101 of the carton blank 1 are folded upward by the folding plate 6 to fold the carton blank 1 into a carton shape. When the carton moves to the bonding mechanism 7, the controller 3 controls the first electric push rod 4 to stop running, and then the controller 3 controls the piston rod of the second electric push rod 711 to extend, so that the tape 704 is attached to the corner of the formed carton, and then controls the piston rod of the third electric push rod 712 to extend. The tape 704 is long, and then the tape 704 is cut. The cut tape 704 is tightly pressed against the folding corner of the formed paper box by the angle iron pressing knife head 713, thereby completing the bonding and fixing of the paper box folding corner. At this time, the piston rod of the third electric push rod 712 is retracted, and then the piston rod of the second electric push rod 711 is controlled to retract, thereby driving the tape 704 to reset. Then the motor 708 drives the waste tape collection roller 707 to rotate to rewind the cut tape 704 for the next bonding operation. Then the controller 3 controls the piston rod of the first electric push rod 4 to continue to move downward to move the paper box out of the forming space. At this time, the paper box is separated from the squeezing of the folding plate 6, and then the controller 3 controls the piston rod of the first electric push rod 4 to retract. At this time, because the volume of the paper box after being released is greater than the volume of the forming space, the pressing block 5 is separated from the inside of the paper box, and then the paper box falls onto the finished product conveyor belt 9, and the pressing block 5 is reset upward.
