Large-rotary continuous feeding and waste discharging system

Abstract

The invention discloses a large-rotary continuous feeding and waste discharging system. The large-rotary continuous feeding and waste discharging system comprises a feeding conveying system, detectionswitches, a rotary cutter set and a control system, wherein the detection switches comprise a first detection switch and a second detection switch so as to respectively detect the positions of the paper head and the paper tail; the rotary cutter set is arranged between a second clamping and conveying unit and a third clamping and conveying unit and used for cutting long-strip paper materials; andthe control system controls the first clamping and conveying unit to operate in an accelerated mode to shorten the distance between the long-strip paper materials at the two ends according to detection signals of the detection switches, then the control system accelerates the cutting frequency of the rotary cutter set to rapidly cut the paper tails and the paper heads of the long-strip paper materials, and finally, a telescopic mechanism is controlled to stretch out and draw back to discharge the paper tails and paper heads. Compared with a traditional paper cutting machine, the large-rotarycontinuous feeding and waste discharging system has the advantages that the head, the tail and finished products of paper are continuously cut off, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of paper cutting. More specifically, the present invention relates to a continuous feed and waste discharge system with large swirls. Background technique [0002] The large rotary paper cutter is an important machine in the high-speed automatic production line of toilet paper and kitchen paper, which can greatly improve the automation degree and production efficiency of the production line. [0003] At present, the feeding method of the large rotary paper cutter is a single paper material feeding independently. In order to ensure the smoothness of the edges of the two ends of the finished product, it is necessary to cut off the head and tail of the paper material. Due to the lack of two continuous strips of paper material The position detection feedback of the paper head and paper tail, the control system can not know its exact position, must wait for the previous paper material to be cut in the process of...

AI Technical Summary

Problems solved by technology

However, the first paper cutter was in an idle state from the end of the head cutting to the tail cutting, which led to an increase in the operating cost of the paper cutter, and the use of the dual-machine working mode not only occupies a larger area , each machine also needs to be equipped with a separate operator to operate, resulting in increased costs
