Printing machine intelligent unwinding device

Abstract

Disclosed is a printing machine intelligent unwinding device. A first guide roller, a second guide roller and a third guide roller are connected between two wallboards. A cylinder is fixed to each wallboard. Each cylinder is connected to a chain. Each chain is connected to a level hook. An inflation shaft is connected to a small idle gear. A magnetic powder brake is connected to one of the wallboards. The magnetic powder brake is connected to a driving wheel. The driving wheel is engaged with the small idle gear. The inflation shaft passes through a paper roll. The inflation shaft passes through the paper roll and is fixed. When a power supply and an air source are turned on and the roll is winded up, the cylinders shrink and drives the chains to run, the chains drive the lever hooks to move up so as to push the paper roll on the inflation shaft closer, the level hooks hook the inflation shaft, the paper roll goes up and falls into a positioning hole for fixation, and the small idle gear is close to the driving wheel. During the unwinding operation, the magnetic powder brake drives the small idle gear to brake through the driving wheel. During winding down, the cylinder extends andthe chains drive the level hooks to move down so as to lower the paper roll on the inflation shaft. The beneficial effects of the printing machine intelligent unwinding device are that the problem ofmanual winding is solved and the production efficiency of unwinding paper is improved.

Description

technical field [0001] The invention belongs to the field of printing machine manufacturing, and in particular relates to an intelligent unwinding device for printing machines. Background technique [0002] In the unwinding process of the known printing machine, the paper rolls are completely loaded and unloaded manually, and the production efficiency is low. There has been no good technical solution for this drawback. Contents of the invention [0003] The intelligent unwinding device of the printing machine of the present invention adopts the cylinder to drive the chain as a lever, which not only can roll paper up and down easily and reliably, but also can roll up large rolls without manual unwinding, which solves the above problems well. [0004] In order to achieve the above object, the intelligent unwinding device of the printing machine of the present invention is realized in the following manner: the first guide roller, the second guide roller and the third guide ro...
