Abstract

The invention relates to a follow-up press roll device controlled by air cylinders. The follow-up press roll device is composed of a wall plate I, a roller device, a press roll device body, an air cylinder assembly and a wall plate II. The roller device is supported on the wall plate I and the wall plate II through supporting parts. The press roll device body is arranged on the wall plate I and the wall plate II and is in contact with the roller device through the air cylinder assembly. The press roll device body is a tightly-pressing mechanism for tightly pressing paper through a press roll,wherein the spiral direction of the left part of the press roll is opposite to that of the right part of the press roll. Due to the fact that the lifting time and the falling time of the press roll are adjusted in a manner that actions of the air cylinder assembly are controlled through an electric system, precise positioning of the paper is guaranteed. Due to the fact that different control programs are set for the electric system according to different paper sizes, direct calling is conducted when the paper sizes change, thus the labor intensity is lowered, and time is saved. Due to the factthat the press roll is a rubber roll body with the spiral direction of the left part being opposite to that of the right part, the paper is flattened, and precision of printed product detection conducted through a laser detection head is guaranteed.

Description

technical field [0001] The invention relates to a sheet-fed inspection machine for inspecting the quality of printed matter in the printing industry, in particular to a cylinder-controlled follow-up roller device. Background technique [0002] After retrieving relevant patent documents, a cylinder-controlled follow-up roller device with the same structure as the present invention has not yet been retrieved. Existing sheet-fed inspection machines generally use conveying rollers and conveyor belts to carry the paper forward for quality inspection of printed matter, but the friction between the paper and the conveying rollers and conveyor belts is not easy to control, which may easily cause the paper to move out of control and wrinkle Uneven, thus affecting the detection performance. In addition, the change of the paper format also puts forward higher requirements on the time of lifting and falling of the pressure roller. As the printing accuracy requirements of sheet-fed off...
