Precision printing machine

Abstract

The invention relates to the field of a printing machine, in particular to a precision printing machine. The precision printing machine comprises a machine shell, an annular card absorbing belt, a paper inlet channel dust-removing roller and a printing head; the dust-removing roller is arranged in front of the annular card absorbing belt and comprises a dust-removing active rotary roller and a dust-removing passive rotary roller; a card dust-removing sensor is arranged in front of the dust-removing roller; the printing head is hinged in front of the card dust-removing sensor; a printing rollerdriven by a printing motor to rotate is arranged below the printing head; transmission gears which are mutually engaged are arranged between a motor shaft of the printing motor and a roller shaft ofthe dust-removing active rotary roller; the control end of the card dust-removing sensor is connected with a card absorbing motor through a cable; a front positioning roller, a back positioning rollerand a positioning sensor are arranged in front of and at back of the printing roller; and the control end of the positioning end is connected with the printing motor through a cable. The precision printing machine provided by the invention is simple in structure, high in printing precision and good in printing effect and can prevent the printing roller or card paper from being worn.

Description

technical field [0001] The invention relates to the field of printers, in particular to a precision printer. Background technique [0002] Printers have been widely used in various fields such as office, industry or commerce to print required documents or other content. Traditional printers have low precision and do not have the function of dust removal, so they cannot be used in applications that require high printing precision. In some industrial fields, if there is a lot of dust on the printing paper, it will affect the printing effect, easily cause wear to the printing roller and other devices, reduce the service life of the equipment, and easily cause paper jams. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a precision printer with simple structure, high printing precision, good printing effect, and preventing abrasion of printing rollers or paper jams. [0004] The present invention is achieved through ...
