Abstract
The invention relates to equipment for pasting films on a windowing paper box, in particular to a film cutting device of a window pasting machine. The device comprises an air suction roller which is rotatably arranged on a rack, a film cutter opening is arranged on one side of the air suction roller, an upper cutter seat is arranged on the cutter opening, an upper cutter is arranged on the upper cutter seat, and at least one lower cutter device which can automatically stretch and return is arranged on the air suction roller. When a film roll enters a cutting-off position, firstly, a thin hole in the surface of the upper roller can carry out vacuum adsorption on the film to enable the film to be attached to the surface of the upper roller, the film is positioned and then is conveyed to a cutter opening, the lower cutter device completely extends out under the combined action of the circular inner track guide rail and the spring to be in contact with the upper cutter to realize cutting, so that the cutting accuracy of the lower cutter device is higher, and the lower cutter device can be automatically retracted into the air suction roller after being cut off to effectively protect the cutter from being abraded.
Description
Technical Field
The invention relates to equipment for pasting films on a windowing paper box, in particular to a film cutting device of a window pasting machine.
Background
The window patching machine is mainly used for window-opening paper boxes such as various window-opening gift boxes, cosmetic boxes, tissue boxes, window-opening corrugated paper boxes and films of envelope bags. The film cutting device of the window patching machine is used for cutting a film roll material into a film sheet material suitable for being pasted on a windowing part of a paper box, and in order to improve the speed, the film cutting device of the window patching machine in the prior art mostly adopts a rolling cutting mode, but the defects are obvious: 1. the film can not be reliably cut off, and the cut film can not be accurately conveyed before leaving the lower roller; 2. the upper and lower cutters are in flat-to-flat contact to cut off the film, the cutting force is large, the abrasion of the cutters is large, and the service life of the cutters is short.
Disclosure of Invention
The invention aims to solve the defects in the prior art and provides a film cutting device of a window patching machine.
In order to achieve the purpose, the invention adopts the following technical scheme:
a film cutting device of a window patching machine comprises an air suction roller which is rotatably arranged on a rack, a film cutter opening is arranged on one side of the air suction roller, an upper cutter seat is arranged on the film cutter opening, an upper cutter is arranged on the upper cutter seat, and at least one lower cutter device which can automatically stretch and return is arranged on the air suction roller.
The lower cutter device comprises an air suction roller inner cutter seat which is arranged on an air suction roller and can be moved, a lower cutter is arranged on the air suction roller inner cutter seat, two ends of the air suction roller inner cutter seat partially protrude out of the air suction roller respectively, the protruding portion is arranged on a U-shaped sliding seat, a return spring is arranged between the bottom of the protruding portion and the U-shaped sliding seat, the U-shaped sliding seat is fixedly arranged on the side wall of the air suction roller, a rolling bearing is arranged on the outer side of the protruding portion, the rolling bearing is arranged on a circular inner track guide rail, the circle center point of the circular inner track guide rail is higher than the circle center axis of the air suction roller, and the lower cutter completely protrudes out of the air suction roller to abut against an upper cutter when reaching a cutter edge so as to cut off a film.
As a further improvement, the central point of the circular inner track guide rail is positioned on the connecting plane of the central axis of the air suction roller and the film cutting edge, so that the lower cutter of the circular inner track guide rail completely protrudes out of the air suction roller to be abutted against the upper cutter when reaching the cutting edge to cut off the film.
The beneficial technical effects of the invention are as follows: when a film roll enters a cutting-off position, firstly, a thin hole in the surface of the upper roller can carry out vacuum adsorption on the film to enable the film to be attached to the surface of the upper roller, the film is positioned and then is conveyed to a cutter opening, the lower cutter device completely extends out under the combined action of the circular inner track guide rail and the spring to be in contact with the upper cutter to realize cutting, so that the cutting accuracy of the lower cutter device is higher, and the lower cutter device can be automatically retracted into the air suction roller after being cut off to effectively protect the cutter from being abraded.
