The glued facial paper is adsorbed on the conveyor belt 20, and is transported to the bottom of the forming machine 30 where the paper and the inner box are bonded, where the facial paper is spliced ​​and formed in the jigsaw machine 40 through [u1] The inner box is glued together. For the structure and principle of the positioning device, please refer to the applicant's another invention patent application 2015106693376 "A precise positioning device and method for the tissue and inner box of a packaging box".

[0045] The inner box is spliced ​​and formed in the splicing machine 40. For the mechanism and principle of the jigsaw machine 40, please refer to the applicant’s another invention patent application 2015106875016 "a device and method for forming an inner box with automatic feeding". The inner box is composed of a long gray board and two short gray boards. There are two creases in the middle of the long gray board to divide the gray board into three parts, corresponding to the bottom surface and two longer sides of the inner box. Two short gray boards The plate corresponds to the two shorter sides of the inner box. When splicing, the splicing machine 40 applies glue on the joint between the long gray board and the small gray board, and the two short gray boards are moved by the splicing machine 40 to the two shorter sides of the suction inner mold and are adsorbed on the inner mold. After the inner mold is lowered, the long gray board is folded along the crease, and the inner mold is positioned by suction. The long gray board wraps the bottom surface and the two longer sides of the inner mold, and completes the splicing of the inner box by short-term extrusion .

[0049] Such as Figure 5 , The small turntable device includes a flexible clamping device 321 (four), a small turntable 322, and a small reduction motor 323. The flexible clamping device 321 flexibly positions the inner box, and the small reduction motor 323 provides power for the rotation of the small turntable 322, so that the small turntable 322 rotates 90 degrees each time. The initial working position of the small turntable device is at the hand-changing mechanism, where the inner box is changed to the small turntable device and fixed, and then the small turntable 322 rotates 90 degrees to transport the inner box to the shovel edge folding mechanism.

[0050] Such as Image 6 The shovel edge folding mechanism includes two box-holding aluminum plates 351, two shovel blades 352, and a die spindle device 353. Two box-holding aluminum plates 351 embrace the long side of the inner box, and then two shovel blades 352 are extended to fold the long side of the facial paper, the die spindle device 353 is lowered, and the folded facial paper is attached to the inner side of the long side of the inner box. After that, the die spindle device 353 rises and separates from the inner box, the small turntable 322 rotates, and the inner box is transported to another shovel-folding mechanism to complete the bonding of the short side of the tissue paper and the inner side of the short side of the inner box. At this time, the entire box-making operation is completed, the small turntable 322 continues to rotate, and the formed carton is transported to the box ejection mechanism.

[0051] Such as Figure 7 , The box ejecting mechanism includes a box pushing mechanism 361 and a box ejecting conveyor belt 362. After the small turntable 322 rotates, the formed carton is located at the front end of the box pushing mechanism 361, and the box pushing mechanism 361 pushes the carton onto the box delivery conveyor belt 362, and the carton is finally transported out of the device by the box delivery conveyor belt 362.
