Problems solved by technology

[0003] After the multi-color offset printing machine finishes printing the magazine, it is transported and dried before being collected. The magazine is printed on both sides. The magazine that has just been printed will be attached to the conveyor belt during transportation, and the conveyor belt will rub off the magazine. Freshly printed ink, resulting in defective products

Embodiment Construction

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] see Figure 1-6 , the present invention provides a technical solution: a multi-color offset printing machine, including an external control mechanism 1 for starting an external control device, a cyclic suction mechanism 2 for cyclic suction, and a back and forth for squeezing the airbag. The airbag blowing mechanism 3 for blowing air, the air flow changing mechanism 4 for squeezing and changing the air flow through, the circula...

Abstract

The invention discloses a multicolor offset press. Comprising an external control mechanism used for starting an external control device, a circulating suction mechanism used for circulating suction, an air bag blowing mechanism used for extruding an air bag to blow air back and forth, and an airflow changing mechanism used for extruding to change airflow passing. The circulating air blowing mechanism is used for blowing air circularly, the elastic jacking mechanism is used for extruding elastic jacking, a shell is arranged in the external control mechanism, and the external control mechanism is provided with a circulating suction mechanism through the arranged shell. The magazines jolt and move through blocking of different wind forces of second fan blades, third fan blades and first fan blades, it is ensured that the magazines are comprehensively blown and dried, arc-shaped rods are elastic rods and can automatically and elastically return to the original position after extrusion is completed, when supporting rods are extruded, rubber pads move downwards, the magnitude of airflow passing through the rubber pads is different, and therefore the effect that the magazines are dried is achieved. And jolting and shaking of magazines are improved.

Description

technical field [0001] The invention belongs to the technical field of offset printing machines, in particular to a multi-color offset printing machine. Background technique [0002] Offset printing press is a type of lithographic printing press. During printing, the printing graphics are first printed from the printing plate to the blanket cylinder, and then transferred from the blanket cylinder to the paper; the offset printing press can be divided into Single-color, two-color, four-color and multi-color printing presses. [0003] The multi-color offset printing machine collects the magazines after they are transported and dried. The magazines are printed on both sides. The newly printed magazines will be attached to the conveyor belt during transportation, and the conveyor belt will rub off the magazines. The ink just printed, which leads to the appearance of defective products. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a mul...
