Paper unfolding and loading machine for product detector

Abstract

The invention discloses a paper unfolding and loading machine for a product detector. The machine comprises a stack piling and paper loading mechanism used for piling up a plurality of thick printing products stacks and conveying the thick printing product stacks, wherein the output end of the stack piling and paper loading mechanism is corresponding to the input end of a lifting and stack dividing mechanism; the output end of the lifting and stack dividing mechanism is corresponding to the input end of a small stack conveying mechanism, wherein the lifting and stack dividing mechanism is used for dividing each thick printing product stack into a plurality of thin printing product stacks as well as conveying out the thin printing product stacks; the output end of the small stack conveying mechanism is corresponding to the input end of a paper unfolding mechanism, wherein the small stack conveying mechanism is used for continuously sequentially conveying each thin printing product stack; the output end of the paper unfolding mechanism is corresponding to the input end of a paper loading and conveying mechanism, wherein the paper unfolding mechanism is used for sequentially performing a paper unfolding work at least twice and a paper releasing work once for each thin printing product stack and then conveying out the thin printing product stacks; the output end of the paper loading and conveying mechanism is corresponding to the input end of a paper feeding mechanism of the product detector, wherein the paper loading and conveying mechanism is used for finishing the paper loading work in a telescopic paper conveying manner. According to the machine, the paper can be continuously fed to the paper feeding mechanism of the product detector after the printing products are subjected to paper unfolding, so that the labor intensity of workers can be greatly reduced, the production efficiency can be improved, and the rate of graded products can be ensured.

Description

technical field [0001] The invention relates to a paper breaking machine for a product inspection machine, and belongs to the technical field of paper loading for a product inspection machine. Background technique [0002] Currently, if figure 1 As shown, the existing inspection machine (also known as small-sheet inspection machine) generally includes a paper feeding mechanism 10, a deviation correction mechanism 20, and a surface quality inspection mechanism 30, wherein: the paper feeding mechanism 10 includes a paper feeding conveying device 11 and its upper Corresponding to the paper feeding knife 13 and the paper supporting board 12, the deviation correction mechanism 20 includes a pair of deviation correction transmission devices 21 correspondingly arranged on the upper and lower sides, and the surface quality detection mechanism 30 includes a suction detection transmission device 31 and a detection device 32 correspondingly arranged above it . Such as figure 1 , in ...

AI Technical Summary

Problems solved by technology

[0003] At present, the product inspection machine is mainly used for small hard cigarette labels (also known as hard cigarette boxes), and the detection speed can reach 130,000 pieces per hour. The height of the paper is limited. It can be seen from this that the labor intensity of manual paper loading is very high. Workers need to continuously feed the paper feeding mechanism 10 and cannot leave. But even so, a worker can only satisfy a maximum of one. The paper loading requirements of the inspection machine

In addition, in order to prevent poorly cut printed matter 41 from entering the market as a genuine product, before putting the printed matter 41 on the paper feeding mechanism 10, workers need to perform paper breaking operations on the printed matter 41, that is, the four "ears" on the hard small cigarette label. ", that is, the folded ears, which need to be broken off (ie pressed out) before loading the paper, otherwise, when the paper feeding mechanism 10 is discharging the paper, the ears of the two overlapping printed matter 41 are easy to scrape together, thereby causing damage to the printed matter 41, And greatly affect the accuracy of subsequent surface quality detection

However, it can be seen from the actual implementation that the manual method of paper breaking has the disadvantages of low production efficiency, high labor intensity, and the inability to ensure the effect of paper breaking, which greatly affects the authenticity rate.
