Non-scratch feeding structure of sheet-fed quality inspection machine

Abstract

The non-scratch discharge structure of the single-sheet printed product quality inspection machine provided by the present invention includes a base, a conveyor belt (3) and a cardboard storage rack, and the base includes at least two side plates (11) and a top plate connecting the two side plates (11) (12), the top plate (12) is partially hollowed out, and the conveyor belt (3) is laid in a part of the hollow track groove of the top plate (12); the cardboard storage rack consists of two fixed horizontal plates (41) and two fixed horizontal plates (41 ) between the two paper support brackets (42), wherein: the two paper support brackets (42) are set oppositely, and the bottom ends of the paper support brackets (42) are equipped with a paper support mechanism, and the two sides of the fixed horizontal plate (41) The ends are correspondingly connected to the tops of the two side plates (11) of the base; below the area between the two fixed horizontal plates (41) there is the hollow track groove, where a part of the track groove is covered with a transmission belt (3 ), and the other part is equipped with a suction cup (5). The invention improves the production efficiency and the quality of cardboard separation.

Description

technical field [0001] The invention belongs to the technical field of printing paper product separation equipment, and in particular relates to a non-scratch discharging structure of a single-sheet printed product quality inspection machine. Background technique [0002] As is well known, most of the paper packaging boxes currently on the market are made of cardboard and bonded by spraying glue. Among them, in order to ensure that the thickness and size of the cardboard and the patterns printed on it meet the standards, it is necessary to test each cardboard in advance. Therefore, installing an automatic paper separation device at the front end of the printed cardboard inspection machine to automatically separate the stacked cardboard is an inevitable requirement to improve production efficiency, and it is also a process method commonly used in the industry at present. [0003] In the prior art, paper separating devices of hook type or knife type structure are often used. ...

AI Technical Summary

Problems solved by technology

[0004] Although the existing paper separation equipment can improve the automation level of printing paper separation, there are many design deficiencies in this equipment

For example, when the cardboard passes through the gap between the limit mechanism and the conveyor belt, it is easily scratched by the hook-shaped or knife-shaped limit mechanism due to contact with it, causing the cardboard to be scrapped

Furthermore, when the cardboard is thin, the practicability of this paper separating device is reduced due to the difficulty in controlling the gap precision, and the cardboard often passes through the paper separation area in an overlapping manner, failing to achieve the purpose of paper separation

In addition, when the cardboard is thicker, there will be abnormal material jams, which not only reduces production efficiency, but also increases costs due to cardboard scrapping
