Embodiment Construction
[0040] In order to make the purpose, features and advantages of the present invention more obvious and understandable, the specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings. Several embodiments of the invention are shown in the drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the present invention will be thorough and complete.
[0041] It should be noted that when an element is referred to as being “fixed on” another element, it may be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. As used herein, the terms "vertical," "horizontal," "left," "right," "u...

The invention discloses an automatic correction system and method for the paper feeding time of a paper feeder, the automatic correction system comprises a detection mechanism used for detecting the paper feeding time of the paper feeder, the detection mechanism comprises a first encoder and a position detection module, and when the position detection module is an inductive switch and the inductive switch triggers a signal, the first encoder is started; the first encoder detects the current angle value, and when the position detection module is the second encoder, the angle difference between the positions of the first encoder and the second encoder is detected and calculated in real time; the logic controller is used for acquiring a current angle value, calculating an angle difference of a standard angle value which is correct with the paper feeding time or an angle difference between the positions of the first encoder and the second encoder, and acquiring a paper feeding time result according to the angle difference; the servo controller is used for setting the paper feeding speed of the paper feeder based on the paper feeding time result, so that the paper feeder corrects the paper feeding time according to the newly set paper feeding speed; the technical problem that in the prior art, the production efficiency is reduced due to paper conveying time errors can be solved.
Description
technical field [0001] The invention relates to the technical field of printing, in particular to a system and method for automatically correcting paper feeding time of a paper feeder. Background technique [0002] In today's society, printing has already become an important part of our daily life. The invention and development of printing presses play a vital role in the spread of human civilization and culture. A printing press is a machine that prints text and images. Generally, the printed text and images are made into a printing plate, which is installed on the printing machine, and then the ink is applied manually or by the printing machine to the place where the text and images are on the printing plate, and then Direct or indirect transfer to paper or other printing substrates to reproduce the same print as the printing plate. [0003] At present, the more common printing machines are sheet-fed printing machines. Sheet-fed printing machines need a feeder to supply p...
