Correspondingly, the core function of the guide mechanism is as follows: separating two adjacent packing boxes 817 in a stacked state, specifically, peeling the packing box 817 closest to the card slot out of the adjusting cylinder 810, while ensuring that another packing box 817 continues to be placed in the adjusting cylinder 810, according to the following working principle: on the same follow-up plate, two adjacent shifting forks 813 are in a group and are correspondingly matched with an adjusting cylinder 810, wherein the shifting forks 813 comprise an L-shaped body 821, in an initial state, the horizontal end of the body 821 is used for supporting the outer edge of the unsealing end of the packing box 817 at the lowermost end, and the vertical height between the upper surface of the horizontal end of the body 821 and the upper surface of the vertical end of the body 821 is greater than the thickness of the outer edge of the unsealing end of the packing box 817, namely when the follow-up plate approaches towards the direction of the packing box 817, sliding friction is generated between the lower surface of the unsealing end outer edge of the packing box 817 and the upper surface of the horizontal end of the body 821 until the outer edge of the unsealing end of the packing box 817 is contacted with the vertical end side wall of the body 821, at the moment, the follow-up plate continues to move, the outer edge of the unsealing end of the packing box 817 is limited by the inner wall of the limiting plate 811, and is limited by the vertical end side wall of the body 821, the outer edge of the unsealing end of the packing box 817 above is guided by the upper surface of the first wedge surface 818 and then is supported by the guide block 819;

when the shifting fork 813 and the follow-up plate move to the extreme positions, the outer edge of the unsealing end of the upper packing box 817 is completely supported by the upper surface of the guide block 819, while the outer edge of the unsealing end of the lower packing box 817 is completely moved out along the channel and finally falls into the clamping groove, namely the lower part of a plurality of packing boxes 817 in the first batch is completed; after the packing boxes 817 are determined to be completely butted with the clamping grooves, the adjusting mechanism reversely drives the follower plate and the shifting fork 813, the follower plate and the shifting fork 813 start to reset, so that the outer edge of the opening end of the packing box 817 located above is limited by the other limiting plate 811, the upper surface of the guide block 819 falls onto the horizontal end of the body 821 through the first wedge-shaped surface 818, namely the upper surface of the horizontal end of the body 821 is the supporting surface of the outer edge of the opening end of the packing box 817, and the adjusting mechanism is repeatedly adjusted, so that the next batch of packing boxes 817 can be placed downwards.

The adjusting mechanisms mainly have two functions, one is that the two follow-up plates are simultaneously pushed to do linear reciprocating motion in the horizontal direction; and secondly, the packing boxes 817 with foreign matters are recycled, so that the next batch of packing boxes 817 are ensured not to be lowered to be affected. When the first function is realized, the push-pull cylinder 805 is started, and the linkage rod 815 drives the two follow-up plates and the plurality of shifting forks 813 positioned on the side walls of the two follow-up plates to perform synchronous linear motion under the guiding and limiting action of the fixed block 816; when the second function is realized, the second function is required to correspond to the detection result of the secondary CCD camera 825 on the side plate 820, that is, when a foreign object is detected in the packing box 817, the telescopic cylinder 828 drives the second suction cup 829 to move in the direction close to the packing box 817 until the outer wall of the packing box 817 is sucked, when the output end of the telescopic cylinder 828 retracts, the stepping motor located at the bottom of the supporting plate 804 drives the rotating shaft 832 to rotate, so that the telescopic cylinder 828 and the second suction cup 829 rotate to the upper side of the accommodating slot 812 after passing through the notch 830 along the circumferential direction of the rotating shaft 832, at this time, the suction of the packing box 817 by the second suction cup 829 is released, that is, the packing box 817 with the foreign object is moved to the conveyor belt 833 in the accommodating slot 812 and finally conveyed to the centralized accommodating place, and the rotating shaft 832, the telescopic cylinder 828 and the second suction cup 829 are reset under the driving of the stepping motor; and the link belongs to a link in the process of putting down the same batch of packing boxes 817.

Preferably, the blanking hole 802 is closed after the packing boxes 817 are filled in the blanking pipe 807, so that an operator cannot timely know the usage amount of the packing boxes 817 in the blanking pipe 807, and therefore, in the embodiment, a plurality of rectangular grooves 803 are vertically formed in two side walls of the blanking box 801 opposite to each other, and the rectangular grooves 803 are communicated with the arc-shaped cuts 808 formed in the outer wall of the blanking pipe 807, so that the operator can observe the same or different consumption conditions of the packing boxes 817 in each blanking pipe 807 in real time, so as to supplement the feeding in time; moreover, due to the specific shape of the packing box 817, a tearing section handle protruding out of the outer edge of the unsealing end exists, when the packing box 817 is placed downwards, the tearing section handle can also penetrate through the arc-shaped notch 808 and then is placed in the rectangular groove 803, and then the limiting and guiding effects are achieved, the packing box 817 is prevented from being rotated in a non-directional mode in the downward placing process, and effective action engagement between the packing box 817 and the adjusting cylinder 810 and the shifting fork 813 is guaranteed.

when the sealing film 515 is placed downwards, the jacking cylinder 517 lifts the connecting rod 519 to the position below the sealing film 515 from the bottom of the bottom plate 506, the first sucking disc 518 at the upper end of the connecting rod 519 is in surface contact with the folded tearing section and adsorbs the tearing section, meanwhile, the jacking cylinder 517 drives the rotating motor 516 and the connecting rod 519 to move downwards again, namely, the sealing film 515 is pulled out of the discharge hole 508, the first sucking disc 518 adsorbs the tearing section after being turned over, and then the tearing section is driven by the rotation of the rotating motor 516, so that when the sealing film 515 covers the packaging box 817, the tearing section is still horizontally placed, the upper surface of the tearing section is kept attached to the first sucking disc 518, when the sealing film 515 is completely aligned with the packaging box 817, the first sucking disc 518 releases the adsorption effect, and the rotating motor 516 drives the connecting rod 519 and the first sucking disc 518 to reset, and film covering operation of the next batch is facilitated.
