CN2452974Y - Rocking arm type high speed paper unwinding frame - Google Patents

Abstract

The utility model relates to a rocking arm type high speed paper unwinding frame which belongs to the field of a paper making machine. The utility model is composed of a first paper unwinding mechanism and a second paper unwinding mechanism. The first paper unwinding mechanism comprises a hydraulic oil cylinder, a machine frame, a shifting fork, a tilting guide rail, a horizontal guide rail and a clamping jaw. The second paper unwinding mechanism comprises one hydraulic oil cylinder, a flying connecting rod, one clamping jaw, a rocking arm and a supporting base. The utility model solves the problems that when the existing paper unwinding mechanism works, the mechanism needs to stop after the paper is placed, and then a rotary arm is rotated, one additional roll is used for guiding paper, the efficiency is lower, and the existing paper unwinding mechanism can not fit the modern high vehicle speed. The utility model can cause the paper page automatically link to another paper roll from one paper roll under the condition that the machine is not stopped and the speed is not reduced, and the adaptive maximum vehicle speed can reach 1500 meters per minute.
