Heat transfer printing printer

Abstract

A heat transfer printing printer comprises a machine base, a printing rubber roller, a printing head bracket, a printing head, a thermal transfer ribbon mechanism, a paper supplying trough, a paper dividing mechanism and a paper feeding mechanism. A lifting mechanism is additionally arranged, first fastening pieces are directly mounted on the power output end of the lifting mechanism, and the lifting mechanism drives the first fastening pieces to lift and drop, so that the printing head and the printing rubber roller are in a closed state or a separation state; meanwhile, a take-up gear and a drive gear are in a meshing state or a separation state; and in the separation state, winding of a thermal transfer ribbon is suspended, so that thermal transfer ribbon waste caused by thermal transfer ribbon empty winding at the time of printing blank data is avoided, the thermal transfer ribbon is saved by a large margin, and printing cost is reduced. Limit partition boards and limit adjustment mechanisms are arranged on the two sides of a paper feeding belt and paper feeding pinch rollers, when the printing head is locally damaged and needs to change the printing position, the positions of the limit partition boards are changed by adjusting the limit adjustment mechanisms of the corresponding limit partition boards, so that the printing head can still print normally under the condition of local damage, and the printing cost is reduced.

Description

technical field [0001] The invention relates to a printer, in particular to a thermal transfer printer. Background technique [0002] In general printers, especially thermal transfer printers, the print head presses the carbon ribbon tightly on the paper for printing. When printing, the carbon ribbon is wound synchronously. When printing blank data, the print head does not heat up, but the carbon The ribbon is wound as usual, but the carbon ribbon is a one-time consumable, which causes a serious waste of the ribbon and increases the printing cost. [0003] In addition, in order to ensure the printing effect, the printing mechanism must accurately align the printing position of the paper. Therefore, during the paper conveying process, the paper must be limited in the left and right directions to ensure that the paper does not move in the left and right direction during the conveying process. The offset on the screen ensures that the printing mechanism can print in the correc...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a thermal transfer printer, which can avoid the waste of carbon ribbon caused by empty winding of the carbon ribbon when printing blank data, greatly save the carbon ribbon, and the print head is partially damaged It can still print normally even under the condition of low printing cost
