Corrugated board printing machine and automatic stop control system for paper feeding failure thereof

Abstract

The invention relates to a corrugated board printing machine and an automatic stop control system for a paper feeding failure thereof, wherein the corrugated board printing machine is provided with a paper feeding machine set, a multi-color printing machine set and at least one work and postprocessing machine set connected in other sequence; the corrugated board printing machine is characterized in that a paper feeding counting sensor is arranged at the paper outlet of the paper feeding machine set; a paper outlet counting sensor is arranged at the paper inlet or paper outlet of the tail end machine set of the corrugated board printing machine; the data obtained by the paper feeding counting sensor and the paper outlet counting sensor are analyzed and processed by a PLC (Programmable logic Controller), and is displayed through a human-machine operation interface. The invention aims to provide an automatic stop control system for a paper feeding failure of the corrugated board printing machine, which can realize automatic stop function of paper feeding failures in printing machines, so that the self-diagnostic protection processing ability of failures in the printing machines is improved, the safety of device and human is ensured, the waste of paper boards is greatly reduced, the operation is convenient, and the work efficiency is improved.

Description

technical field [0001] The invention relates to a corrugated cardboard printing machine and its automatic control system, in particular to an automatic stop control system for a unit-type corrugated printing machine for paper feed failure. Background technique [0002] With the development of printing machinery technology, there are higher requirements for the safety protection measures of printing machinery. The production of fully automatic high-precision printing machines has always been the development trend of the printing machinery industry. All printing and packaging industries are also constantly putting forward the guarantee requirements for strengthening the safety of printing press equipment, reducing the loss of paper and other substrates, and improving work efficiency. [0003] Existing corrugated cardboard printing machines usually have a paper feeding unit and a subsequent processing unit, which usually include four major units: a dust removal unit, a multi-co...

Problems solved by technology

[0006] However, this alarm device only sets a paper jam fault alarm for the paper feeding part, and does not set the paper feeding part to automatically stop the paper feeding system, and cannot detect paper jams in other parts of the equipment such as the printing unit part, drying part and die-cutting part. Timely and effective alarm for faults, but there are still potential safety hazards that the paper jam alarm is not timely and cannot automatically shut down
