Background
The laminating machine forms a paper-plastic integrated product by coating adhesive on the plastic film, pressurizing the plastic film and a printing stock by a blanket cylinder and a heating cylinder, and then combining the plastic film and the printing stock. In the use process of the laminating machine, the film is unreeled by the film roll, after the old film roll is about to be unreeled, the new film roll is connected with the old film roll, and then the old film roll is cut off, so that the roll replacement can be completed without stopping, and the unreeling is continuously carried out. Because the joint is formed by stacking and pasting two films, the joint needs to be skipped during the subsequent compounding; in winding, it is also necessary to control the position of the cut-off at the joint. Currently, for the joint identification mode, a color adhesive tape is usually stuck at the joint, the corresponding position is detected by a color sensor, and when the color sensor detects the adhesive tape, the cutting operation can be performed at the corresponding position. However, in this way, when the printing material is pressed on the film, the color sensor is likely to detect a false detection due to the numerous colors on the printing material, thereby causing a cutting position error.
