on the basis of the structures of the above embodiments, the mold removing actuator included in the mold removing assembly may include a second lifting mechanism 23 and a second suction cup mechanism 24 that are connected to each other, as shown in fig. 1 and fig. 8, when the blank subjected to the cover opening process by the cover opening assembly is conveyed to the mold removing assembly along the second conveyor belt 2, the second lifting mechanism 23 (the second lifting mechanism 23 here is a slide rail structure, but other common linear motion mechanisms disposed along the vertical direction may also be used) drives the second suction cup mechanism 24 to descend to a position where the upper cover of the blank can be adsorbed, the second suction cup mechanism 24 immediately vacuumizes and tightly adsorbs the mold in the blank with the opened upper cover, and the second lifting mechanism 23 drives the second suction cup mechanism 24 to move upward, thereby completing the operation of removing the mold in the blank.

Here, can design the box base and do the short time and stay when conveying to the drawing module subassembly to wait for the drawing module executive component to carry out the drawing operation to it, here can realize the short time stay of box base through the conveying step pitch of computer timing control second conveyer belt 2, also can set up the inductor and carry out the response detection to the position of box base, when the inductor detects that the box base conveys to the drawing module subassembly, the inductor feedback signal makes its pause drive to the power unit that drives second conveyer belt 2, when the inductor detects that the box base leaves the drawing module subassembly, the inductor feedback signal makes its continuation drive to the power unit that drives second conveyer belt 2.

The mould taking executive component has a simple and economical structure, and can ensure that the mould taking processing of the box blank is accurate and reliable. Of course, a robot-like structure may be chosen here, which grips and removes the mold in the blank.

Example eleven:

based on the structure of the tenth embodiment, it can be designed that the above mold-taking actuator further includes a first translation mechanism 25 connected to the second suction cup mechanism 24, and the first translation mechanism 25 can drive the second suction cup mechanism 24 to horizontally translate between the position above the mold in the opened blank and the position where the mold is blanked.

In the embodiment shown in fig. 1 and 8, the first translation mechanism 25 (the first translation mechanism 25 here is a slide rail structure, but other common linear motion mechanisms disposed along a horizontal direction may also be selected) and the second lifting mechanism 23 form a bidirectional linkage mechanism, a mold blanking channel 26 is disposed at a mold blanking position, when the second lifting mechanism 23 drives the second suction cup mechanism 24 to move upward, and when an operation of taking out a mold from a blank is completed, the first translation mechanism 25 drives the second suction cup mechanism 24 to move to a feed port of the mold blanking channel 26, and the second suction cup mechanism 24 releases the taken out mold to drop into the mold blanking channel 26 for ordered blanking, so that the mold can be recycled in a production and processing process of a packaging box.

Of course, the first translation mechanism 25 and the second lifting mechanism 23 can also be designed to form a three-axis linkage mechanism, and when processing blanks of different sizes, the first translation mechanism 25 can adjust the second suction cup mechanism 24 to be right above the mold in the blank, so as to ensure the stability of the second suction cup mechanism 24 in mold removal processing of the molds in the blanks of different sizes.

Example twelve:

Similarly, the second limiting structure is used for limiting the blank when the mold taking executing part takes the mold in the blank, so that the problem that the blank is difficult to take out the mold from the blank due to the fact that the blank follows the mold when the mold taking executing part drives the mold in the blank to move is avoided.
