Easy-to-use press take-up roll assembly

Abstract

The invention discloses a paper winding roller assembly convenient to use and applicable to a printing machine. The assembly comprises a rotating shaft (1), wherein one end of the rotating shaft (1) is connected with a fixed drum (2); one end of the fixed drum (2) is connected with a moving drum (3); two arc-shaped fixed fastening tiles (4) and two arc-shaped moving fastening tiles (5) are symmetrically arranged on the outer surface of the fixed drum (2) and the outer surface of the moving drum (3) respectively; a first spring (6) is connected between the two fixed fastening tiles (4); and a second spring (7) is connected between the two moving fastening tiles (5). The assembly can improve the clamping stability and the paper winding stability, can prevent a paper core from deviating and has the advantages of being convenient to use and large in application range.

Description

technical field [0001] The invention relates to a paper winding roller assembly of a printing machine, in particular to a conveniently used paper winding roller assembly of a printing machine. 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. Therefore, the existing paper roll has the problems...

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.

Therefore, the existing paper rolls have the problems of poor clamping stability, easy displacement of the paper core, inconvenient use and small application range.
