At this time, the part of the first sealing label 710 that is not pasted to the upper surface 610 will be suspended to the outside of the packaging box 600. Similarly, the second suction cup 320 of the label removing component 300 is used to suck the second sealing label 720, and the part of the second sealing label 720 that is not pasted to the upper surface 610 is also suspended to the outside of the packaging box 600. The state of the packaging box 600 at this moment is as follows. Figure 5 As shown; then, the first brush 410 of the first labeling component 400 rotates to fold the first sealing label 710 at the edge where the upper surface 610 and the first end surface 620 intersect, so as to stick the overhanging portion of the first sealing label 710 to the first end surface 620. Similarly, the second brush 510 of the second labeling component 500 rotates to fold the second sealing label 720 at the edge where the upper surface 610 and the second end surface 630 intersect, so as to stick the overhanging portion of the second sealing label 720 to the second end surface 630. At this point, the pasting operation of the first sealing label 710 and the second sealing label 720 at both ends of the packaging box 600 is completed; finally, the conveying function of the conveying component 200 can be continued to be used to transfer the packaging box 600 with the sealing labels pasted to the next station.

[0053] The packaging box sealing label sticking device can realize automatic sticking of the sealing label of the packaging box 600 through the above-mentioned configuration. The whole process basically does not require human intervention, thereby effectively reducing labor intensity and well solving the problems existing in the prior art.

[0054] It should be noted that, in this embodiment, the “first direction” can be Figure 3 and Figure 4 The direction indicated by the arrows ab in the middle indicates that the “second direction” can be Figure 3 and Figure 4 The direction indicated by the arrow cd in the middle indicates.

[0055] Please continue to refer to Figure 1In this embodiment, the labeling equipment may further include a feeding feeder 020 and a four-axis robot 010, wherein the feeding feeder 020 and the four-axis robot 010 are both installed on the frame 100, and the feeding feeder 020 is used to supply the first sealing label 710 and the second sealing label 720 to the label picking component 300; the label picking component 300 is installed on the free end of the four-axis robot 010, and the four-axis robot 010 drives the label picking component 300 to rotate, translate and lift, so as to realize the position change of the label picking component 300 in the horizontal and vertical directions, thereby meeting the requirements of label picking and pasting.

[0056] Please continue to refer to Figure 3 and Figure 4 In this embodiment, the conveying component 200 may include a first conveying belt 210 and a second conveying belt 220 that are arranged in parallel and at intervals; the packaging box sealing label pasting device may also include a limiting component 800, wherein the limiting component 800 includes a blocking block 810 that is lifted and disposed between the first conveying belt 210 and the second conveying belt 220, and the blocking block 810 is used to prevent the packaging box 600 from continuing to move forward when the packaging box 600 flows to the pasting station.

[0057] When the packaging box 600 is transferred to the pasting station via the first conveyor belt 210 and the second conveyor belt 220, the blocking block 810 of the limiting assembly 800 will extend upward to prevent the packaging box 600 from continuing to move forward, so that the label removal assembly 300 can smoothly paste the first sealing label 710 and the second sealing label 720 to the two ends of the packaging box 600 at the pasting station.

[0058] By setting the conveying assembly 200 as a belt transmission mechanism mainly composed of the first conveying belt 210 and the second conveying belt 220, not only the structure is simple, but also reliable transportation of the packaging box 600 can be achieved. By setting the limiting assembly 800, the packaging box 600 in the pasting station can be mechanically limited, so that the conveying assembly 200 can achieve the pasting of the first sealing label 710 and the second sealing label 720 without stopping; after the pasting of the first sealing label 710 and the second sealing label 720 is completed, the blocking block 810 descends to release the limiting effect on the packaging box 600, so that the packaging box 600 can continue to flow forward.

[0059] Please continue to refer to Figure 3 and Figure 4 In this embodiment, the design of the power mechanism of the first conveyor belt 210 and the second conveyor belt 220 can refer to the prior art. This embodiment does not make any improvements to this, so it will not be repeated.

[0065] When the packaging box 600 is transferred to the pasting station, when the support plate 910 rises to support the packaging box 600, the vacuum suction cup 930 arranged on the support plate 910 can be turned on to adsorb the packaging box 600 to prevent the packaging box 600 from shifting during the pasting operation of the sealing label, thereby ensuring the stable position of the packaging box 600.

[0066] Please continue to refer to Figure 7 In this embodiment, the number of the vacuum suction cups 930 can be multiple, and the multiple vacuum suction cups 930 are dispersedly arranged on the bearing surface.

[0067] This arrangement can increase the suction area and suction points of the vacuum suction cup 930 on the packaging box 600, thereby improving suction reliability.

The piston rod of the lifting cylinder 920 extends upward from the fixing plate 940 and is fixedly connected to the support plate 910. The cylinder body of the limiting cylinder 820 is installed on the fixing plate 940.

[0069] This arrangement can not only realize modular installation of the lifting assembly 900, but also improve the integration of the limiting assembly 800 and the lifting assembly 900, so that they can be installed together on the rack 100 as a whole.
