Rotating barrel assembly for printing machine paper winding and application method thereof

Abstract

The invention relates to the technical field of printing mechanical equipment, in particular to a rotating barrel assembly for printing machine paper winding. The rotating barrel assembly comprises arack, a driving device, a first inner barrel, a second inner barrel, a first outer barrel and a second outer barrel. The first inner barrel is connected to the surface of the rack in a rotary manner,and the end of the first inner barrel is connected with the driving device. The second inner barrel is concentrically arranged above the first inner barrel in an inserted and sleeved manner through akey groove. The second outer barrel is concentrically arranged above the first outer barrel in an inserted and sleeved manner through a key groove. The first outer barrel is coaxial with the first inner barrel. A gear ring is fixedly connected to the lower end of the first outer barrel. According to the rotating barrel assembly, by means of a tensioning mechanism, the clamping force borne by papercores in the winding and rolling process is increased; the problem that the paper cores are off position is avoided; stability, achieved in the working process, of the paper cores is improved; meanwhile, the rotating barrel assembly can meet working demands of the paper cores of different diameters can be met; the rotating barrel assembly is easy to operate, reasonable in design and convenient touse; the application scope of the paper cores is widened; and the automation degree of the rotating barrel assembly is effectively raised, and production efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of printing machinery and equipment, in particular to a rotary cylinder assembly for roll paper of a printing machine and a use method thereof. Background technique [0002] At present, the structure used for rolling paper in printing machines is generally a paper roll, which connects the paper core through the paper roll and drives the paper core to rotate, so as to carry out paper feeding and rolling; Both sides of the paper roll are clamped. However, when the existing paper roll rolls, the clamping stability is poor, which causes the paper core to be easily displaced. Moreover, only paper cores with specified diameters can be installed when rolling paper. When winding paper cores with different diameters, it is necessary to replace the winding roll or add auxiliary sleeves of corresponding specifications, which is inconvenient to use and has a small scope of application. The low degree of human particip...

However, when the existing paper roll rolls, the clamping stability is poor, which leads to the easy deviation of the paper core

Moreover, only a paper core with a specified diameter can be installed when rolling paper. When winding paper cores with different diameters, it is necessary to replace the paper roll or add an auxiliary sleeve of the corresponding specification, which is inconvenient to use and has a small scope of application.
