Printing consumable composite exhaust device

Abstract

The invention discloses a printing consumable composite exhaust device. The device comprises an exhaust cutter shaft, a plurality of groups of exhaust cutter sets which are located on the exhaust cutter shaft, and a driving transmission set which is installed at the end part of the exhaust cutter shaft and used for driving the exhaust cutter shaft to rotate; the exhaust cutter shaft is located onone side of the consumable, and the arrangement direction is perpendicular to the advancing direction of the consumable; the plurality of groups of exhaust cutter sets are attached to the surface of the consumable; and the exhaust cutter shaft is driven by the driving transmission set to rotate, the exhaust cutter sets are used for cutting the consumable, and the cutting direction is consistent with the advancing direction of the consumable. According to the device, the exhaust device is arranged between a gluing drying station and a composite station, a plurality of exhaust ports are cut in the consumable through the exhaust cutter sets of the exhaust device, so that when the consumable and printing paper are compounded, air can be effectively discharged, the situation of unsmooth exhaustduring compounding is avoided, the generation of bubbles is prevented, and the printing quality of the consumable is ensured.

Description

technical field [0001] The invention relates to the composite field of printing consumables, in particular to an exhaust roller of composite equipment. Background technique [0002] In advanced printed matter, it is usually necessary to mount a transparent plastic film on the printing consumable product, that is, the film. The lamination is divided into "light film" and "dumb film". The surface effect of the glossy film is crystal clear and bright, while the matte film is a foggy surface, and the printed matter after lamination has a matte matte surface. [0003] This application focuses on the coating of printing consumables. The compounding of printing consumables is divided into hot compounding and cold compounding. The thermal compounding of consumables will cause adverse effects on the surface of the consumables after high temperature, which will affect the printing quality. The cold lamination is just laminating the two consumables at room temperature, but in the su...

Problems solved by technology

The compounding of printing consumables is divided into thermal compounding and cold compounding. The thermal compounding of consumables will cause adverse effects on the surface of consumables after high temperature, which will affect the printing quality.

And cold lamination is just laminating two kinds of consumables at room temperature, but in the subsequent process or subsequent use, air bubbles will be generated, especially in high temperature environments.
