Paper conveying device

Abstract

A paper conveying device comprises a framework, a paper conveying platform, a paper deviation correcting and limiting mechanism, a paper detecting mechanism, a paper absorbing and positioning mechanism and a batch type paper feeding mechanism. The paper deviation correcting and limiting mechanism, the paper detecting mechanism, the paper absorbing and positioning mechanism and the batch type paper feeding mechanism are arranged on the paper conveying platform, the paper deviation correcting and limiting mechanism forms a paper limiting area on the paper conveying platform, the paper detecting mechanism, the paper absorbing and positioning mechanism and the batch type paper feeding mechanism are respectively arranged in the paper limiting area, and the paper detecting mechanism is electrically connected with the paper absorbing and positioning mechanism. The paper conveying device is capable of preventing slanting or deviating of paper by deviation correcting and position limiting of the paper deviation correcting and limiting mechanism and absorbing and positioning of the paper absorbing and positioning mechanism, so that paper can be stably reliably conveyed, accuracy of printing and processing of paper printing and processing equipment and accuracy of printed matter quality detection and code spraying equipment detection are guaranteed.

Description

technical field [0001] The present invention relates to a paper conveying device, more specifically, the present invention relates to a paper conveying device in paper printing and processing equipment or printing quality testing and coding equipment. Background technique [0002] In paper printing processing equipment or printed matter quality inspection and inkjet equipment, it is often necessary to use a paper conveying device to continuously convey paper or printed matter (that is, paper printed with patterns and / or characters, hereinafter referred to as paper) continuously, so that Paper printing processing equipment can accurately print paper, so that printed matter quality inspection and inkjet equipment can accurately detect printed matter. [0003] However, in the process of conveying paper by the existing paper conveying device, the paper tends to be skewed and shifted, and sometimes even wrinkled, which affects the accuracy of the printing process of the paper pri...
