The cutting knife structure 20 comprises a driving motor 51, a driving shaft 52, a knife holder 50 and a cutting knife 53, wherein the driving motor 51 is fixedly connected with the bracket, one end of the driving shaft 52 is connected with the power output end of the driving motor 51, the other end of the driving shaft 52 is connected with the knife holder 50, and the cutting knife 53 is correspondingly arranged below the knife holder 50; the upper surface of the cutting base 54 is provided with a cutting abdicating groove 57 for inserting the cutting knife 53. In actual operation, the driving motor 51 drives the driving shaft 52 to drive the tool post 50 to move towards the cutting base 54, and after the adhesive tape 46 placed on the cutting base 54 is cut by the cutting knife 53, the driving motor 51 drives the driving shaft 52 to drive the tool post 50 to reset, so as to prepare for the next cutting operation. The cutting abdicating groove 57 is arranged to correspond to the cutting knife 53, so that the cutting quality is improved.

The bottom of the cutting seat 54 is connected with a lifting motor B56 through a lifting shaft B55; and an anti-wrinkling auxiliary pressure roller 49 connected with the support in a rolling manner is arranged above the adhesive roll mounting roller 48, and when the adhesive roll 41 is mounted on the adhesive roll mounting roller 48, the outer surface of the anti-wrinkling auxiliary pressure roller 49 is kept in contact with the outer surface of the adhesive roll 41 in an attaching manner.

The upper surface of the cutting seat 54 is provided with a plurality of air blowing holes 19, an air storage cavity 47 is arranged in the cutting seat 54, and the air storage cavity 47 is connected with an external air source through a pipeline. In practical operation, in order to clamp the adhesive tape 46 by the finger clamping cylinder 61, the cutting knife structure 20 cuts off the adhesive tape 46 and then resets, the lifting motor B56 drives the cutting base 54 to move a next predetermined distance through the lifting shaft B55, then the external air source is started to blow air out from the air blowing holes 19, so that the adhesive tape 46 is blown to a corresponding height, and the finger clamping cylinder 61 moves to a position corresponding to the cutting base 54 to clamp the adhesive tape 46 and then pull out.

The upper surface of the cutting seat 54 is coated with an anti-sticking coating. By providing the anti-sticking coating, the adhesive tape 46 is prevented from sticking to the upper surface of the cutting base 54 and affecting the smoothness of the pulling-out operation.
