Since the two side surfaces of the through groove pass through the lifting block 14, the connecting block 15 can slide in the through groove of the inner cavity of the lifting block 14, which is convenient for taking the connecting block 15 out of the inner cavity of the lifting block 14. The bottom surface of 15 is fixedly connected with a die 18 for folding the carton. The specifications of the die 18 are the same as those of the slot on the top surface of the forming mold 3. After the cardboard is placed on the top surface of the forming mold 3, the hydraulic cylinder 13 is turned on, so that the hydraulic cylinder 13 drives the lifting block 14 to move downward, and the lifting block 14 drives the die 18 to move downward through the connecting block 15, so that the die 18 can press against the cardboard and enter the inner cavity of the forming mold 3, and the cardboard can be folded. Since the two sides of the through groove pass through the lifting block 14, when the lifting block 14 is taken out from the inner cavity of the connecting block 15, it will also drive the die 18 to move, thereby replacing the die 18 that is compatible with the forming mold 3.

[0029] The bottom surfaces of the lifting block 14 and the connecting block 15 are both provided with a plurality of threaded holes 16. The threaded holes 16 aligned with the bottom surfaces of the lifting block 14 and the connecting block 15 are threadedly connected with bolts 17. After the connecting block 15 is placed in the inner cavity of the lifting block 14 and the positions of the two threaded holes 16 are aligned, the bolts 17 are inserted into the two aligned threaded holes 16 and the threaded self-locking is used to fix the connecting block 15 in the inner cavity of the lifting block 14, thereby fixing the position of the die 18.

[0030] The inner walls on both sides of the groove 2 are provided with transverse grooves 4, and the inner walls on both sides of the two transverse grooves 4 are rotatably connected with rotating shafts 5. The circumference of the two rotating shafts 5 and the inner cavity of the transverse grooves 4 are fixedly sleeved with gears 6. One end of the two rotating shafts 5 passes through the workbench 1 and is fixedly connected with a turning handle 9. The two turning handles 9 are both arranged on one side of the workbench 1.

The inner cavities of the two transverse grooves 4 are both provided with There is a stopper 7 for limiting the forming mold 3. The opposite ends of the two stoppers 7 can pass through the transverse groove 4 and be set in the inner cavity of the groove 2, and one side of the stopper 7 is against one side of the forming mold 3, and the distance between one side of the stopper 7 and the inner wall of one side of the groove 2 is the same as the length of the forming mold 3, so that after one side of the forming mold 3 is against the inner wall of one side of the groove 2, the stopper 7 will be against the other side of the forming mold 3, so that the forming mold 3 is fixed in the inner cavity of the groove 2, and the upper halves of the opposite sides of the two stoppers 7 are fixed. The gear 6 is fixedly connected with a rack 8 engaged with the gear 6. The two racks 8 are respectively arranged above the two gears 6. The top surface of the rack 8 is in the same horizontal plane as the top surface of the stopper 7, and the rack 8 is engaged with the gear 6. When the gear 6 is driven to rotate by the turning handle 9, the gear 6 will drive the engaged rack 8 to move laterally, and the lateral movement of the rack 8 will drive the stopper 7 to move laterally, that is, the stopper 7 can pass through the transverse groove 4 into the inner cavity of the groove 2, and the stopper 7 can be pressed against the forming mold 3, so that the position of the forming mold 3 can be fixed. When the forming mold 3 needs to be replaced, the turning handle 9 is rotated in the opposite direction, and the gear 6 can be driven to rotate in the opposite direction through the rotating shaft 5, so that the rack 8 moves in the opposite direction, and then drives the stopper 7 to enter the inner cavity of the transverse groove 4. At this time, the forming mold 3 is taken out from the groove 2, and the forming mold 3 adapted to the specifications of the cardboard folding is replaced and placed in the groove 2 for fixing, so as to facilitate the folding of cartons of different specifications, avoid the folding device can only fold cartons of one specification, improve the efficiency of carton folding.
