The output end of the color mark sensor 22 is electrically connected to the input end of the electric control box 2, and the output end of the electric control box 2 is electrically connected to the input end of the drive assembly, the label collecting roller 13 and the top support assembly respectively.

[0028] As an optional embodiment, the driving assembly includes a telescopic cylinder 9, one end of the telescopic cylinder 9 is rotatably connected to the side panel of the equipment frame 1, and the other end is rotatably connected to the lower fork of the three-pronged connecting plate 7.

[0032] With the above structure, the labeling roll is installed on the material tray 10, and the label is pulled to abut against the two guide rollers 12, and then to abut against one of the label separation rollers 14 and pulled horizontally. It is pulled to the right from under the label stripping plate 15 and then to the left from above it. After passing the other label separation roller 14, it is fixed to the label receiving roller 13 through the plug-in fixing part 4. When the stacked paper cup tubes slide down along the inclined guide plate 5, they abut against the barrier 8 and stop. At this time, the label suction square tube 19 and the two top label arc frames 18 are located under the stacked paper cup tubes. As the label receiving roller 13 is controlled to rotate, the label paper tape is driven to be reeled. When the label paper moves to the right side of the label stripping plate 15, the label paper is separated from the paper tape due to the left shift (see Figure 4 ), and the label-absorbing square tube 19 is adsorbed on its surface, and then the top support assembly is controlled to drive the label-absorbing square tube 19 and the two top label arc-surface frames 18 to perform a first displacement upward. At this time, the label-absorbing square tube 19 initially adheres the label paper to the surface of the stacked paper cup tubes, and then the two top label arc-surface frames 18 are controlled to rise at the same time for a second displacement. The two sides of the label paper are bent into an arc shape through the arc surface of their surfaces and fit with the arc surfaces of both sides of the stacked paper cup tubes. After the fitting is completed, the driving assembly is controlled to drive the three-pronged connecting plate 7 to flip upward, and drive the label-absorbing square tube 19 and the two top label arc-surface frames 18 to retract. At this time, the stacked paper cup tubes with the labels completed can fall along the inclined guide plate 5.
