Waste paper treatment device for carton green printing

Abstract

The invention belongs to the technical field of waste paper treatment for carton production lines, and particularly relates to a waste paper treatment device for carton green printing. The waste papertreatment device comprises an air duct. The outer tube wall of an outer half tube of the air duct is fixedly connected with an ash cleaning broom, the broom surface of the ash cleaning broom extendsdownwardly in the extending direction of the air duct to the surface of a carton at a discharging guide rail of a printing machine, the broom surface of the ash cleaning broom is perpendicular to theguiding direction of the discharging guide rail, and an air outlet of the air duct is directed to the intersection of the portion, at the discharging guide rail, of the surface of the carton and the ash cleaning broom. The device comprises a dust whisking motor. A felt tray is fixedly connected to the shaft end of a rotating shaft of the dust whisking motor. The felt tray surface is perpendicularto the guiding direction of the discharging guide rail, and the tray edge of the felt tray abuts against the portion, at the discharging guide rail, of the surface of the carton. The device further comprises a waste paper conveying belt. The waste paper conveying belt is communicated with external waste paper treatment equipment. The waste paper treatment device has the beneficial effects of beingsimple in structure, easy, convenient and quick to operate, low in cost and capable of achieving the automatic waste removal operation while the cleanliness of the surface of a corrugated cardboard is ensured.

Description

technical field [0001] The invention belongs to the technical field of waste paper treatment for carton production lines, and in particular relates to a waste paper treatment device for green printing of cartons. Background technique [0002] Corrugated box is made of corrugated cardboard, after die-cutting, creasing and gluing. It is the most widely used packaging product, and its consumption has always been the first among all kinds of packaging products. At present, the production of corrugated boxes has basically realized the automatic operation of printing, slotting, die-cutting, box gluing, and packaging. In actual production, when gluing boxes, the bonding is often unreliable, which leads to the quality of carton forming not meeting customer needs, causing customer complaints. In addition, after the corrugated carton packaging is completed, it can be clearly seen that there is a large amount of waste paper and waste paper ash on the surface of the carton, which serio...

AI Technical Summary

Problems solved by technology

The above waste paper blocks and waste paper ash are attached to the surface of corrugated cardboard under the action of static electricity, which will lead to the failure of subsequent adhesive coating and the extremely poor cleanliness of the carton surface

In addition, when corrugated cardboard is grooved, there will always be some leftovers after groove cutting that adhere to the grooved part and cannot be discharged normally, which also brings certain troubles to the subsequent gluing and even packaging operations.
