Roller clamping and positioning device for multifunctional web press

Abstract

The invention relates to the technical field of printing, in particular to a roller clamping and positioning device for a multifunctional web press, which comprises a frame body, an inflating and deflating mechanism is arranged in the middle of the front side of the frame body, a transfer mechanism is arranged in the front part of the frame body, a roll loading and unloading mechanism and a clamping mechanism are respectively arranged on the left and right sides in the rear part of the frame body, the bottom side of the rear part of the frame body is provided with a roll unloading groove body, and the bottom side of the front part of the frame body is provided with a driving mechanism. The inflating and deflating mechanism comprises a fixed frame erected in the middle of the front side of the frame body, adjusting air cylinders erected in the fixed frame in a bilateral symmetry mode, and a movable frame fixedly connected between the output ends of the two adjusting air cylinders. By adjusting and controlling a rotating disc to rotate by 90 degrees, a new paper roller is pushed to a roll feeding station and moves to the working station, and automatic replacement of the paper roller is achieved. Meanwhile, the unwound paper roller is moved down from a roll unloading station and collected in a centralized mode, so that the labor intensity of workers is effectively reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a cylinder clamping and positioning device for a multifunctional web printing machine. Background technique [0002] Common printing methods include offset printing and flexographic printing. Offset printing can restore the color, contrast and level of the original with high precision and clarity. It is currently the most common paper printing method. For high-end printed products, it is necessary to perform flexographic printing on a flexographic printing machine first. After printing, transfer to an offset printing machine for offset printing, or first perform offset printing on an offset printing machine and then transfer to a flexographic printing machine for flexographic printing, thus forming a multi-mode intelligent printing unit based on an offset printing platform. Usually, a multi-mode intelligent printing unit includes an unwinding unit, an offset printing platform, a...
