Method and device for manufacturing and locating window patching packaging material

Abstract

The invention relates to a method and a device for manufacturing and locating a window patching packaging material. A photoelectric sensor is used to detect a locating mark signal on a thin film, the rotation speed signal of a cutting-off roll is obtained by encoder detection, the photoelectric sensor is adopted to detect a cutter position signal, the signals are subjected to signal comparison and error calculation by an operation processor so as to control a servo motor, the servo motor controls a feed roll to deliver the thin film to the cutting-off roll, and the thin film is cut by a cutter on the cutting-off roll. The device comprises a guide roll, the photoelectric sensor, the feed roll, the servo motor, the operation processor, a touch screen, the cutting-off roll, the cutter and the encoder. Compared with prior arts, the invention realizes automatic bonding between a windowed film and a single-sheet windowed paper box, achieves accurate alignment, automatically corrects cutting-off position deviation without influencing the original production speed of the window patching machine, accurately locates and bonds the windowed film and the single-sheet windowed box, and keeps accurate locating of image / text positions on the windowed film.

Description

technical field [0001] The invention relates to a method and a device for packaging materials, in particular to a method and a device for making a positioning window-attached packaging material. Background technique [0002] In the existing newly designed tissue box, the film is pasted on the window of the carton after the window is opened. After the window of the carton is opened, the window of the film is smaller than the window of the carton. To achieve the purpose of safety and sanitation. [0003] Since the window of the film and the window of the single-sheet carton have to correspond, the existing window sticking machine cannot be connected to open the window of the film. It can only be bonded to the single-sheet carton after the window is opened, so that the alignment cannot be guaranteed. Accurate, can only be fitted by hand, and the production efficiency is low. Contents of the invention [0004] The object of the present invention is to provide a method and de...
