A paper feeding system for a printing machine

Abstract

The invention belongs to the technical field of printing equipment, and particularly relates to a paper feeding system of a printing press. The paper feeding system comprises a paper separation assembly, a first guide roller (4), a second guide roller (5), an ultrasonic double sheet detection component (10) and a conveying assembly (6). The paper separation assembly, the first guide roller (4), the second guide roller (5) and the conveying assembly (6) are arranged in the conveying direction of paper sheets (1) in sequence. The paper separation assembly enables the paper sheets (1) to be separated and conveys the paper sheets (1) to the first guide roller (4), the first guide roller (4) conveys the paper sheets (1) to the second guide roller (5), the second guide roller (5) conveys the paper sheets (1) to the conveying assembly (6), the conveying assembly (6) conveys the paper sheets (1) to the printing press (8), and the ultrasonic double sheet detection component (10) is arranged between the second guide roller (5) and the conveying assembly (6). The paper feeding system can effectively avoid the phenomenon that a plurality of paper sheets are conveyed together, and avoid paper sheet waste and printing faults.

Description

technical field [0001] The invention belongs to the technical field of printing equipment, and in particular relates to a paper feeding system of a printing machine. Background technique [0002] A printing press is a machine for printing text and images. A modern printing press generally consists of mechanisms such as plate loading, ink application, embossing, and paper feeding. At present, the printing environment of most printing companies is far from the standard of the printing environment. After the printing machine has been used for a long time, it often happens that several sheets of paper are fed together, which wastes a lot of paper and increases the cost of use. Manual maintenance is often performed, which wastes a lot of labor, and manual maintenance is likely to cause errors. [0003] The Chinese invention patent with the application number 201410403190.1 discloses a fully automatic paper feeding and unloading dual-purpose machine, including a body, a worktable...

Problems solved by technology

But at present, the printing environment of most printing factories cannot meet the requirements of constant temperature and humidity. There is a lot of static electricity between the printed papers, and the stacked papers are easy to stick, and the papers are arched and sometimes jammed. Usually, the way to eliminate static electricity needs to be in the standard Under the temperature and humidity environment, put the paper statically for 3-4 hours and wait for the static electricity to disappear naturally. The paper will be jammed due to static electricity or several sheets of paper are fed together, which will affect the work efficiency, and even cause the printing machine to malfunction in severe cases.
