Description

Technical Field

It is only necessary to manually put the PET bottle into the feeding channel 2, and the label separation process does not need to occupy other labor costs. In the label removal process, a certain amount of labor cost and time cost can be saved.

[0028] Specifically, a connecting block 11 is installed at the lower end of the first telescopic rod 4, and a first driving structure 12 is installed at the front end of the connecting block 11.

When the PET bottle in the label removal box 1 is separated from the label, the intercepting net 25 will descend. At this time, the above steps can be repeated and a new PET bottle can be placed in the label removal box 1.

[0037] The method of use of this embodiment is as follows: the PET bottle is vertically fed into the interior of the label removal box 1 through the feeding channel 2, and the PET bottle is clamped by the clamping structure 6, the clamping structure 6 is first driven to rise by the first telescopic rod 4, so that the rotating cover 23 contacts the bottle cap of the PET bottle, the rotating cover 23 is driven to rotate by the second driving structure 22, and the bottle cap of the PET bottle is removed, and the first telescopic rod 4 drives the clamping structure 6 to descend, and the first driving structure 12 drives the connecting rod 5 and the clamping structure 6 to rotate toward the water outlet 9, so that the waste water inside the PET bottle is discharged through the water outlet 9, and finally the first telescopic rod 4 drives the connecting rod 5 and the clamping structure 6 to descend to the rotating Above the turntable 7, release the clamping structure 6, and the PET bottle falls to the surface of the second mounting groove 26 at the upper end of the rotating disk 7.
