Paper feeding mechanism with paper recognition function and working method thereof

Abstract

The invention discloses a paper feeding mechanism with a paper recognition function and a working method thereof. The paper feeding mechanism with the paper recognition function comprises a front-back adjusting power, a sliding shaft, a front fixed beam, a split type or integrated paper feeding head and a linear moving device which are positioned on a paper feeding part, in addition, the paper feeding mechanism with the paper recognition function further comprises a recognition system, a recognition system support, a front-back moving cross beam and a left-right moving cross beam, and the recognition system is arranged on the paper feeding part or a paper conveying part. According to the paper feeding mechanism with the paper recognition function and the working method thereof, the states of the front side and the back side of the paper can be automatically detected in the paper feeding or conveying process, a paper overturning system is automatically controlled to finish overturning of the paper, manual visual paper inspection and manual paper overturning can be completely replaced, the problem that the states of the front side and the back side of the paper cannot be recognized in the paper feeding or conveying process is effectively solved, production efficiency is high, adaptability is good, and use is flexible.

Description

technical field [0001] The invention relates to a paper feeding mechanism and a working method of a printing and packaging machine, in particular to a paper feeding mechanism with a paper identification function and a working method thereof, belonging to the field of printing and packaging machinery. Background technique [0002] Mechanical equipment such as flat die-cutting machines are the most widely used printing and packaging machinery. The paper feeding mechanism is an important working system in the whole machine. The paper is separated by the paper separation nozzle on the paper pile, and then the paper is passed to the paper feeding part by the paper transfer nozzle to adjust the paper conveying speed and time, and then conveyed to the next process. However, due to the high humidity, the paper with front and back sides mounted by all laminating machines in our country must be dried first before die-cutting, because the paper will be bent and deformed to varying degr...

AI Technical Summary

Problems solved by technology

However, due to the high humidity, the paper with front and back sides mounted by all laminating machines in our country must be dried first before die-cutting, because the paper will be bent and deformed to varying degrees during the drying process , so it will seriously affect the work of feeding paper to the die-cutting process, and cause certain difficulties to enter the die-cutting process. Therefore, before die-cutting, the bent and deformed paper should be stacked forward and backward by manual or mechanical means. , to reduce the bending degree during the drying process by offsetting the deformation amount each other. Since the paper is laminated by the backing paper and the face paper and has a front and a back side, the paper sent by the paper system must be required in the die-cutting process. The orientation of the paper is the same, which requires that before the die-cutting, the reverse side of the paper must be turned over manually or using a flipping machine, so that the front and back of all the paper are in the same direction, and then the die-cutting machine enters the paper feeding system , due to the large amount of labor and low efficiency of manual paper turning, and the mechanical paper turning works independently and there is no close online cooperation with the die-cutting machine, it will still affect the working efficiency of die-cutting and increase production costs
