Description
Technical Field
The invention belongs to the technical field of printing machinery, and particularly relates to a roller structure of a sleeve flexographic printing machine.
Background
The plate roller part of the flexographic printing machine is one of the core components of the printing machine, and the quality of the mechanism and the cost of equipment are influenced. The common structure of the plate roller of the flexographic printing machine is that a triangular support is externally hung outside a wallboard of the printing machine, and a double-layer guide rail and a bearing seat are arranged on the triangular support so as to realize the longitudinal and transverse movement of the plate roller. The mechanism has the advantages of large structure, poor strength, inconvenient installation, larger central roller and high cost due to the large structure.
Disclosure of Invention
The invention aims to provide a roller structure of a sleeve flexible printing machine, which solves the problems of large roller structure, poor strength and inconvenient installation of the flexible printing machine in the prior art.
The technical scheme adopted by the invention is that the printing roller structure of the sleeve flexible printing machine comprises a pair of linear guide rails horizontally fixed on a wallboard, the two linear guide rails are sequentially arranged from top to bottom and are mutually parallel, moving seats are respectively arranged on the two linear guide rails, a fulcrum shaft is horizontally connected on each moving seat, a printing roller seat is arranged between the two fulcrum shafts, the printing roller seat can horizontally and transversely slide along the two fulcrum shafts, a printing roller core shaft is further arranged at the central position of the printing roller seat, and a color register lead screw is further arranged at the upper part of the printing roller seat; the driving part of the end head of the chromatography lead screw is connected with a transverse motor through a coupler, a pressure regulating lead screw is further installed on the movable seat, a belt wheel is installed on the pressure regulating lead screw, the pressure regulating lead screw is driven by the pressure regulating motor to rotate through the belt wheel, and the original driving of the whole structure is a printing roller driving motor.
The present invention is also characterized in that,
the plate roller seat is arranged on the fulcrum shaft through a shaft sleeve.
The printing roller mandrel is arranged on the printing roller seat through a bearing.
The fixed end of the color register screw rod is arranged on the plate roller seat, and the nut end of the color register screw rod is arranged on the movable seat.
The invention has the advantages that when the transverse color register is needed, the transverse motor drives the screw rod to drive the plate roller seat to move on the shaft of the movable seat, so that the transverse color register is realized; when pressure is required to be adjusted, the pressure adjusting motor drives the pressure adjusting screw rod to rotate through the belt wheel, and the pressure adjusting screw rod drives the printing roller seat to longitudinally move through the moving seat, so that printing pressure adjustment is realized. In this way, the linear guide rail is directly installed on the wall plate, and one layer of linear guide rail is omitted, so that the structure is small, the wall plate and the central roller can be small, the cost is saved, and the assembly and installation are convenient; the linear guide rails are distributed on the upper side and the lower side of the plate roller seat, the distance is large, the stress is good, and the structure is stable and reliable. .
