Printhead rubber roller driving servo device, thermal transfer printing apparatus and control method thereof

Abstract

The application relates to a printing head rubber roller driving servo driving device, a thermal transfer printing equipment and a control method thereof. The printing head rubber roller driving servo driving device comprises a rack, a plurality of printing head rubber roller assemblies and a driving mechanism, the printing head rubber roller assemblies are sequentially and movably installed on the rack along a paper feeding and discharging direction, the printing head rubber roller assembly comprises a printing head rubber roller and a rubber roller frame, both ends of the printing head rubber roller are rotatably installed on the rubber roller frame, the second printing head rubber roller arranged adjacent to a paper inlet is used as a driving printing head rubber roller, the rubber roller frame where the driving printing head rubber roller is arranged is a driving rubber roller frame, the driving mechanism is installed on the driving rubber roller frame, the driving mechanism is connected with and drives the driving printing head rubber roller to rotate on the driving rubber roller frame, and the driving mechanism comprises a driving servo motor. By additionally arranging the driving mechanism, the second printing head rubber roller arranged adjacent to the paper inlet is used as the driving printing head rubber roller, and the driving mechanism is used for driving, so that the printing horizontal line defect can be eliminated from the root of dynamics.
