Description

Double-sided device of printer

Technical Field

The utility model belongs to an important component of a printer, and particularly relates to a double-sided device of the printer.

Background

Printers are document output devices that are used more frequently by everyday offices. Some small-sized office scenes or household individuals use the printer, because of the considered machine cost, a few lower-end printers are usually used, and because of cost control of manufacturers, the printer is usually designed to be simpler in some structures, such as a paper feeding structure, a double-sided mechanism, a paper discharging structure and the like. Therefore, a paper jam is easily generated at the time of use, and particularly, a paper jam phenomenon is more easily generated at the time of use of double-sided printing. If the paper used is of poor quality, the paper is thin, or the paper is wet, which can cause paper jams especially when passing through a printer duplex printing apparatus.

As is common, the double-sided printing turnover device of the laser printer of the running chart P3010-3060 series, P3300 series and M700-M6800-M7100-M7200A4 conveys the paper by the guiding conveying function of the double-sided conveying roller and the double-sided conveying guide wheel. When the paper passes through the double-sided device, only the unilateral roller that receives is carried, and the another side does not have any auxiliary device, therefore the reliability greatly reduced of carrying, when the relatively poor paper of use quality or paper have the condition of weing, after having printed the photographic fixing heating of first face through the printer, can produce the bending, crooked paper gets into double-sided device or when the double-sided device gets into to print the counterpoint roller, because the paper front end is crooked, leads to the card paper very easily.

SUMMERY OF THE UTILITY MODEL

An object of the present invention is to provide a duplex apparatus of a printer capable of solving at least one of the above-described problems.

According to one aspect of the utility model, the double-sided device of the printer comprises a base, a double-sided conveying roller wheel assembly, a double-sided conveying guide wheel assembly and a polyester sheet, wherein the double-sided conveying roller wheel assembly and the double-sided conveying guide wheel assembly are arranged on the base, the double-sided conveying roller wheel assembly comprises a double-sided conveying roller wheel, the double-sided conveying guide wheel assembly comprises a double-sided conveying guide wheel, the double-sided conveying roller wheel, the double-sided conveying guide wheel and the polyester sheet are sequentially arranged along the length direction, the polyester sheet is arranged on the base, and the bottom end surface of the polyester sheet is arranged in an arc shape.

The utility model has the beneficial effects that: by providing the polyester sheet, when the paper is conveyed by the double-sided conveying roller and the double-sided conveying guide wheel in the double-sided conveying roller assembly and the double-sided conveying guide wheel assembly, the paper moves to the front side of the double-sided conveying guide wheel; because, the arc is personally submitted to the bottom of polyester chip for the paper is led and is flattened by the bottom face of polyester chip, has reduced the crookedness of paper front end greatly, makes the paper can enter into the counterpoint roller of printer smoothly and prints, avoids appearing the card paper phenomenon.
