[0021] In an embodiment, as shown in Figure 1 , in order to realize feeding of the packaging box 4, the gantry 1 is further provided with a de-stacking and stacking device 8, and the de-stacking and stacking device 8 is located at the feeding end of the feeding conveying line 2. Through the de-stacking and stacking device 8, the packaging boxes 4 stacked into a pile can be placed on the feeding conveying line 2, and the empty packaging boxes 4 can be stacked into a pile.

[0022] As shown in Figure 1 , Figure 2 , the de-stacking and stacking device 8 comprises a de-stacking and stacking movement mechanism 81 and a de-stacking and stacking mechanism 82. The de-stacking and stacking movement mechanism 81 comprises a de-stacking horizontal movement assembly 811, a de-stacking longitudinal movement assembly 812 and a de-stacking lifting assembly 813.

[0024] When the depalletizing and stacking device 8 is working, the depalletizing and stacking moving mechanism 81 first moves the carton suction cup 821 to above the stacked packaging boxes 4, then the carton suction cup 821 adsorbs the packaging boxes 4, and then the depalletizing and stacking moving mechanism 81 moves the packaging boxes 4 to the feeding end of the feeding conveyor line 2 and puts them down. The feeding conveyor line 2 in this embodiment can be an existing material conveyor line that can transport the packaging boxes 4.

[0025] The packaging box 4 is first conveyed to the unpacking device 5 on the feeding conveyor line 2, and the unpacking device 5 opens the packaging box 4. However, before opening the packaging box 4, it needs to be straightened to ensure that the packaging box 4 is conveyed to the predetermined unpacking position.

[0026] like Figures 3 to 5 As shown, in order to achieve the straightening of the packaging box 4, the box opening device 5 also includes a box straightening mechanism 54. The box straightening mechanism 54 includes two straightening components 541 and two straightening baffle assemblies 542, which are arranged sequentially along the conveying direction of the packaging box 4. The two straightening components 541 and the two straightening baffle assemblies 542 are located on opposite sides of the feeding conveyor line 2.

[0027] Furthermore, the straightening baffle assembly 542 includes a straightening baffle drive cylinder 5421 and a straightening baffle 5422. The straightening baffle drive cylinder 5421 is fixed to the gantry frame 1 by screws, and the output end of the straightening baffle drive cylinder 5421 is connected to the straightening baffle 5422 by screws. When the packaging box 4 is conveyed to the bottom of the unpacking device 5, the straightening baffle drive cylinder 5421 first drives the straightening baffle 5422 to move closer to the packaging box 4, and makes the straightening baffle 5422 contact the packaging box 4.

[0028] The corrective baffle assembly 542 also includes a detection sensor, which comprises a transmitter 5423 and a receiver 5424. The transmitter 5423 is fixed to the corrective baffle drive cylinder 5421 by screws, and the receiver 5424 is fixed to the corrective baffle 5422 by screws.

Then, the light beam emitted by the emitter 5423 is reflected by the packaging box 4 and received by the receiver 5424 to trigger a signal, and the homing driving member 5411 is started to drive the homing plate 5413 to move, thereby homing the packaging box 4.

[0033] Then, the cutter 52 is driven by the two robots 51 to move, and the two end portions of the packaging box 4 are cut by the cutter 52, and the adhesive tape for pasting the two long covers of the packaging box 4 is cut along the length direction of the packaging box 4. Then, the box cover suction disc 53 is driven by the robot 51 to move, and the two long covers are first lifted by the box cover suction disc 53, and then the two short covers are lifted. Finally, the cutter 52 is driven by the robot 51 to move along the four peripheral edges of the plastic film bag, and the plastic film bag is cut.

[0034] After the plastic film bag is cut, the homing assembly 541 returns to the original position, and the feeding conveying line 2 conveys the packaging box 4 to the waste removing device 6. As shown in FIG. 6, the waste removing device 6 comprises a waste removing driving member 61, a waste removing plate 62 and a waste removing connecting plate 63.

[0037] The puncture component 612 is an existing product, which can be the W-type needle suction cup disclosed in the patent with authorization announcement number CN214003296U, which punctures plastic film and sponge plate with stainless steel needle.

[0038] After the packaging box 4 moves below the opening device 5, the longitudinal removal component 641 first moves the piercing component 612 above the plastic film and sponge board. Then, the removal lifting component 642 moves the piercing component 612 downward, causing the stainless steel needles on the piercing component 612 to pierce the plastic film and sponge board. Next, the removal lifting component 642 moves the piercing component 612 above the packaging box 4, and the longitudinal removal component 641 moves the piercing component 612 above the waste bin 63. Then, the pressing drive component 621 moves the pressing plate 622 downward. During the downward movement of the pressing plate 622, the pressing plate 622 presses down the plastic film and sponge board on the piercing component 612 until the plastic film and sponge board fall into the waste bin 63.

[0039] After the cut plastic film and sponge board are removed from the packaging box 4, the packaging box 4 is then transported to the packaging box handling device 7 by the feeding conveyor line 2.

Preferably, the short cover closing driving member 9312 is a pneumatic cylinder.

[0053] In the process of moving the packaging box 4 to the left by the transverse conveying assembly 912, the short cover closing driving element 9312 on the left side drives the first closing pressing plate 9311 to move to the middle part of the transverse conveying assembly 912, and the left short cover is pressed down and closed by the first closing pressing plate 9311.

[0054] In the process of moving the packaging box 4 to the left, the short cover closing driving element 9312 on the right side can drive the first closing pressing plate 9311 to move to the middle part of the transverse conveying assembly 912, and the right short cover is supported by the right first closing pressing plate 9311, so as to avoid the right short cover from being folded outwardly of the packaging box 4, and make the right short cover be vertical or be folded inwardly of the packaging box 4 by a certain angle. The length of the transverse conveying assembly 912 can be slightly longer than the length of the packaging box 4, and in the process of moving the packaging box 4 to the left, the right first closing pressing plate 9311 can also be in contact with the right short cover. At this time, the right short cover can be folded outwardly of the packaging box 4 by a certain angle.

[0055] As shown in Figure 12 , in order to avoid the long cover on the packaging box 4 from being folded outwardly, the box cover closing mechanism 93 further comprises a supporting assembly 933, and the supporting assembly 933 is located between the two first short cover closing assemblies 931.

The transverse closing moving element 9341 and the longitudinal closing moving element 9342 can be cylinders. The longitudinal closing moving element 9342 is connected with the output end of the transverse closing moving element 9341, the transverse closing moving element 9341 is fixed on the recycling bottom plate 94, and the recycling bottom plate 94 is fixed on the gantry 1 by screws. The output end of the longitudinal closing moving element 9342 is fixed with a closing adjusting fixed plate 9343, and the two first short cover closing assemblies 931 and one supporting assembly 933 are fixed on the closing adjusting fixed plate 9343 by screws.

[0057] In one embodiment, there may be two cover adjustment components 934, with one cover adjustment component 934 connected to another support component 933, thereby adjusting the position of the other support component 933.

[0058] By setting the lid adjustment component 934, the position of the first short lid lid assembly 931 and the stop assembly 933 can be adjusted, so that the lid lid closing mechanism 93 can be used for packaging boxes 4 of different sizes.

[0059] In one embodiment, the height of the first closing pressure plate 9311 is higher than the height of the baffle plate 9331. Therefore, after the packaging box 4 is conveyed to the transverse conveying assembly 912, the lifting assembly 911 first moves the short cover of the packaging box 4 to a height corresponding to the first closing pressure plate 9311, and then closes the short cover on the left side. After the short cover on the left side is pressed down, the lifting assembly 911 moves the packaging box 4 downward. At this time, the first closing pressure plate 9311 is located above the lid of the packaging box 4, and the baffle plate 9331 can contact the long cover.

[0062] An adjustment groove is provided along the height direction of the cover height adjustment plate 9323. An adjustment bolt passes through the adjustment groove and is threadedly connected to the cover support rod 9322. Tightening the adjustment bolt fixes the cover height adjustment plate 9323 to the cover support rod 9322. Loosening the bolt allows the cover height adjustment plate 9323 to move up and down, thereby adjusting its height and consequently adjusting the height of the second cover pressure plate 9321. The end of the second cover pressure plate 9321 closest to the first cover pressure plate 9311 has an arc-shaped cross-section.

[0063] In the process of conveying the packaging box 4 to the recycling conveying mechanism 92, one end of the second cover pressing plate 9321 in the arc structure first contacts the short cover on the right side of the packaging box 4, and the short cover on the right side is pressed down by the second cover pressing plate 9321 as the packaging box 4 is conveyed. Then the packaging box 4 continues to convey to the right to realize the covering of the long cover.

[0064] In the embodiment, before the packaging box 4 is conveyed to the right, the long cover can be pressed down to a certain angle into the packaging box 4 by the blocking plate 9331 driven by the blocking plate driving cylinder 9332, so as to facilitate the pressing down of the long cover by the second cover pressing plate 9321.
