Unit type flexo printing machine driving system

Abstract

The invention relates to a unit type flexo printing machine driving system, which is applied to printing machine driving system in which an edition roller and an impressing roller of a flexo printing machine are in light pressure contact, and belongs to the fields of light industrial machinery and automatic control. The unit type flexo printing machine comprises guide rollers, a main driving shaft, an impressing roller, a motor, a speed changing box, an edition roller, a driving synchronous belt or a gear and an overlapping curve roller. The unit type flexo printing machine driving system is characterized in that the impressing roller is coaxially driven through the main driving shaft, the edition roller is driven by the motor separately, and line speeds on the surfaces of the edition roller and the impressing roller are synchronous and consistent. The driving power of the overlapping curve roller 4 is provided by an edition roller motor or the main driving shaft through the gear or the synchronous belt.

Description

technical field [0001] The invention relates to a transmission system of a unit type flexo printing machine, which is applied to the transmission system of a printing machine such as a flexo printing machine and other plate rollers and embossing rollers in light pressure contact, and belongs to the field of light industrial machinery and automatic control. Background technique [0002] For traditional unit type flexographic printing machines, especially web flexographic printing machines, the transmission reduction mechanism has a mechanical shaft for transmitting power on the transmission side of the flexographic printing machine. The printing unit is driven by a common mechanical long shaft, through gear reduction and transmission, it drives the embossing roller, version roller and anilox roller to rotate according to the inherent speed change ratio. The printing repetition length of the gear drive flexo printing machine increases with the number of teeth of the plate cyli...

AI Technical Summary

Problems solved by technology

Because the traditional flexo printing machine is printed by a pair of gears on the plate cylinder and the impression roller, when the thickness of the substrate is too thin (12μm) or too thick (0.6mm), the mutual meshing of the two gears is not in place. On the pitch circle of the gear, the gear is easy to shake or wear during transmission, and it is difficult to ensure high-precision and high-quality printing effects

[0003] The transmission system of the electronic shaft group type flexo printing machine, each color group is independently driven by a servo motor, and drives the embossing roller, plate roller and anilox roller to rotate according to the inherent variable speed ratio, which cannot overcome the above-mentioned weaknesses and increases the cost. cost increase

[0004] Each color group is independently driven by 4 servo motors to drive the embossing roller, plate roller, anilox roller and horizontal register respectively. It is a relatively complete solution, but the cost and cost are greatly increased, and the control complexity is increased. The debugging and installation time of the system is increased, and it is only limited to the use of high-end machines and cannot be popularized
