Non-stop winding and unwinding reel soft package material offset press

Abstract

The invention discloses a non-stop winding and unwinding reel soft package material offset press. The non-stop winding and unwinding reel soft package material offset press comprises an unwinding assembly, an offset printing unit set and a winding assembly which are sequentially arranged, wherein the unwinding assembly comprises a first unwinding base and a second unwinding base which are arranged left and right; a cut-off tool is arranged between the first unwinding base and the second unwinding base; extrusion wheels are arranged on the two sides of the cut-off tool; the extrusion wheels are arranged on corresponding moving seats; the moving seats are connected with corresponding horizontal driving assemblies; a storage assembly is arranged between the unwinding assembly and the offset printing unit set; the winding assembly comprises a rotating frame; the rotating frame is in transmission connection with a rotating motor; a first winding seat and a second winding seat are arranged on the rotating frame left and right; a swing frame is arranged close to the rotating frame and is hinged onto a rack and connected with a first swing driving assembly; a rubber roller and a swing block are arranged on the swing frame; a cutter is connected onto the swing block; and the swing block is connected with a second swing driving assembly. According to the non-stop winding and unwinding reel soft package material offset press provided by the invention, the non-stop winding and unwinding operation of the offset press can be realized.

Description

technical field [0001] The invention relates to a printing machine, in particular to an offset printing machine for rewinding and unwinding rolls of soft packaging materials without stopping the machine. Background technique [0002] The offset printing machine is a kind of lithographic printing machine. When printing, the printed image and text are printed from the printing plate to the rubber cylinder, and then transferred to the paper by the rubber cylinder. The traditional offset printing machine is equipped with a single unwinding and rewinding seat. After unwinding or rewinding is completed, it needs to be stopped and replaced with a new unwinding roller and rewinding roller, which leads to unsmooth processing of the whole equipment. , affecting the efficiency of offset printing processing. Contents of the invention [0003] In view of the deficiency of the background technology, the technical problem to be solved by the present invention is to provide a non-stop re...
