A kind of driving device of printing head and thermal printer thereof

Abstract

The invention provides a driving device for a printing head. The driving device comprises a first driving piece, a connecting support and a second driving piece, wherein the first driving piece is arranged on a printer base, and provided with a first output shaft; the connecting support is connected with the first output shaft in a driven mode, and can conduct reciprocating motion relative to a to-be-printed position; the second driving piece is provided with a second output shaft and a second cylinder body, the second output shaft is fixedly connected with the connecting support, and the second output shaft stretches out and draws back to enable the second cylinder body to conduct reciprocating motion between the to-be-printed position and a printing position; and the printing head has a motion state that the printing head can move along the second cylinder body. According to the driving device for the printing head and a thermal printer, the driving piece drives first stage press of the printing head to the to-be-printed position, and the second driving piece drives second stage press of the printing head to the printing position, so that the two-stage press of the printing head are driven through the two driving pieces, and the printing head can accurately stay at three different positions of the highest position, the to-be-printed position and the printing position.

Description

technical field [0001] The invention relates to the field of printers, in particular to a drive device for a print head and a thermal printer thereof. Background technique [0002] At present, the thermal transfer technology uses a special carbon ribbon to transfer the toner coating on the carbon ribbon to paper or other types of materials by using the print head after heating. Choose according to your needs to produce strong adhesion, coupled with the choice of printing media, can ensure that the printed handwriting will not be affected by the outside world. For thermal transfer coding equipment, at different times, the print head needs to stay at three positions with different heights and directions, namely the highest position when the ribbon is installed, the waiting position after the power-on self-test is completed, and the printing position during printing. When the printer is turned off, the print head is at the highest position, so that the ribbon can pass under th...
