The setting and use of the mounting holes 718 provide a guarantee for the stable installation of the Z-shaped duct 714; a servo motor 76 is fixedly installed on the lower end of the other side of the lifting bracket 73, and the output end of the servo motor 76 rotates and passes through the lifting bracket 73 and is fixedly sleeved with a connecting ring 77 at its end, and a symmetrically distributed multi-stage electric push rod 78 is fixedly inserted on the connecting ring 77, and the end of the output end of the multi-stage electric push rod 78 is fixedly sleeved with a connecting sleeve block 79, and a symmetrically arranged mounting countersunk hole 719 is provided on the connecting ring 77, and the multi-stage electric push rod 78 is fixedly sleeved with a connecting sleeve block 79. The rod 78 is fixedly inserted in the mounting countersunk hole 719. The setting and use of the mounting countersunk hole 719 provide a guarantee for the stable insertion of the multi-stage electric push rod 78. The label removal scraper 710 is fixedly installed on the connecting sleeve 79. The upper end of the lifting bracket 73 is provided with a plug-in slot 711, and a removable industrial socket 712 is inserted in the plug-in slot 711.

[0030] By adopting the above technical scheme, the electric telescopic rod 72 will drive the lifting support 73 to move downward, and then the hot air blower 74 and the label removing scraper 710 will move downward, and the electric telescopic rod 72 will be paused when the label removing scraper 710 moves to the appropriate height. At this time, the hot air blower 74 will be started to blow hot air to the label of the packaging box through the air guide flat nozzle 75, so as to soften and reduce the viscosity of the corresponding label glue. Then, the multi-stage electric push rod 78 close to the side of the corresponding packaging box will be started, and then the corresponding connecting sleeve block 79 and the label removing scraper 710 will move to the side close to the first conveying belt mechanism 2, and the label with softened and reduced viscosity will be scraped on one side. Then, the electric telescopic rod 72 will drive the hot air blower 74 and the label removing scraper 710 to move upward and reset, so as to completely remove the label of the packaging box. Then, the multi-stage electric push rod 78 will drive the label removing scraper 710 to reset, and then the servo motor 76 will drive the connecting sleeve ring 77 to rotate one hundred and eighty degrees, so as to drive the two label removing scrapers 710 to rotate one hundred and eighty degrees. During this period, the removed label will rotate with the label removing scraper 710 and be attached to the label collecting board 713 when passing through the label collecting board 713. When the removed label is attached to the label collecting board 713, the electromagnetic valve 716 will be started to guide part of the hot air to the Z-shaped pipe 714 through the side connecting pipe 717, and then the corresponding hot air will be guided into the air guide horizontal pipe 715 and be guided to the connection between the removed label and the label removing scraper 710 by the air guide horizontal pipe 715.

[0031] The disengaging mechanism 9 comprises a disengaging support 91, which is fixedly connected with the outer end frame 1. A servo motor 92 is fixedly installed on one side upper end of the disengaging support 91.

A disengaging push plate 94 is threadedly sleeved on the disengaging lead screw 93 and slidably connected with the disengaging support 91. Symmetrically distributed limiting guide rods 95 are fixedly inserted into the disengaging support 91. Symmetrically arranged limiting guide holes 96 are formed in the upper end of the disengaging push plate 94 and the limiting guide rods 95 slidably penetrate through the limiting guide holes 96. The limiting guide rods 95 and the limiting guide holes 96 cooperatively limit and guide the movement of the disengaging push plate 94.

[0032] By adopting the above technical solution, if the label is qualified, the package box after labeling will be moved to the other end of the first conveyor belt mechanism 2 and unloaded; if the label is unqualified, when the package box after labeling moves to the bottom of the disengagement bracket 91, the first conveyor belt mechanism 2 will be paused and the servo motor 2 92 and the second conveyor belt mechanism 3 will be started. At this time, the servo motor 2 92 will drive the disengagement screw rod 93 to rotate alternately in forward and reverse directions, thereby driving the disengagement push plate 94 to do a reciprocating motion, and then the package box with unqualified labeling can be pushed to the first conveyor belt mechanism 2 and pushed to the second conveyor belt mechanism 3 for transportation.

[0033] The storage mechanism 10 includes a servo motor 3 101, which is fixedly mounted on the side of the outer end frame 1 close to the second conveyor belt mechanism 3, and the end of the output end of the servo motor 3 101 is fixedly connected to a storage rotating rod 103, which is rotatably inserted on the outer end frame 1, and the storage rotating rod 103 is fixedly sleeved with symmetrically distributed storage gears 104, and a storage cross plate 102 is slidably mounted on the outer end frame 1, and the two sides of the bottom end of the storage cross plate 102 are fixedly mounted on the outer end frame 1. A storage rack 105 is fixedly installed on each of them, and the storage rack 105 is meshed with the storage gear 104. A T-shaped guide block 106 is fixedly installed on the bottom end of the storage cross plate 102 away from the storage gear 104. A limiting guide groove 11 is provided through the lower end of the outer end frame 1, and the upper end of the T-shaped guide block 106 is slidably inserted in the limiting guide groove 11. The coordinated use of the T-shaped guide block 106 and the limiting guide groove 11 plays a limiting and guiding role in the movement and adjustment of the storage cross plate 102.

[0034] By adopting the above technical solution, the servo motor 3 101 will intermittently drive the two storage gears 104 to rotate forward and reverse, thereby being able to drive the storage cross plate 102 to move horizontally through the storage rack 105, and then being able to make the storage cross plate 102 intermittently move away from or close to the side of the first conveyor belt mechanism 2, and further being able to receive and temporarily store the packaging boxes after the labels are removed and move them back when the packaging boxes after the labels are removed are reworked.

[0035] Working principle: When in use, the packaging boxes to be processed will be gradually moved by the first conveyor belt mechanism 2. During the transfer, the packaging mechanism 4, the labeling mechanism 5 and the camera detection mechanism 6 can automatically pack and label the packaging boxes. The labeled packaging boxes can also be visually recognized by the 3D camera to determine whether the labels are properly attached.

[0036] If the label is attached, the packaging box will be moved to the other end of the first conveying belt mechanism 2 and discharged. If the label is not attached, the first conveying belt mechanism 2 will be stopped and the second conveying belt mechanism 3 will be started when the packaging box moves to the position directly below the disengaging support 91. At this time, the servo motor 92 will drive the disengaging screw 93 to rotate in the opposite direction, so that the disengaging push plate 94 can move back and forth, and the packaging box with an unattached label can be pushed to the second conveying belt mechanism 3 for conveying.

[0037] At the same time, the electric telescopic rod 72 will drive the lifting support 73 to move down, and then the hot air blower 74 and the label removing shovel 710 will move down. When the electric telescopic rod 72 moves to the appropriate height, it will be stopped. At this time, the hot air blower 74 will be started, so that the hot air can be blown to the label of the packaging box through the air guide flat nozzle 75, so that the glue of the corresponding label can be softened and the adhesion can be reduced. Then, the multi-stage electric push rod 78 close to the side of the corresponding packaging box will be started, so that the corresponding connecting sleeve block 79 and the label removing shovel 710 can move to the side close to the first conveying belt mechanism 2, and the corresponding label with softened glue and reduced adhesion can be scooped up. Then, the electric telescopic rod 72 will drive the hot air blower 74 and the label removing shovel 710 to move up and reset, so that the label with an unattached label can be completely scooped up. Then, the multi-stage electric push rod 78 will drive the label removing shovel 710 to reset. Then, the servo motor 76 will drive the connecting sleeve ring 77 to rotate 180 degrees, so that the two label removing shovels 710 can rotate 180 degrees. During this period, the removed label will rotate with the label removing shovel 710 and will be attached to the label collecting plate 713 when passing through the label collecting plate 713. When the removed label is attached to the label collecting plate 713, the electromagnetic valve 716 will be started, so that part of the hot air can be introduced into the Z-shaped conduit 714 through the side connecting pipe 717. Then, the corresponding hot air will be introduced into the air guide horizontal pipe 715 and will be guided to the connection between the removed label and the label removing shovel 710 by the air guide horizontal pipe 715.

[0038] During this period, the servo motor 101 will intermittently drive the two storage gear wheels 104 to rotate in the opposite direction, so that the storage rack 105 can drive the storage horizontal plate 102 to move horizontally, so that the storage horizontal plate 102 can move away from or close to the first conveying belt mechanism 2 intermittently. Further, the packaging box after label removal can be taken and temporarily stored, and can be moved back and placed when the packaging box after label removal is reworked.

Thus, if these modifications and variations of the present application belong to the scope of the claims of the present application and their equivalent technologies, the present application also intends to include these modifications and variations.
