Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a fast printing device for accounting sheets and invoices for financial use, which has smooth feeding of voucher paper, is not easy to be stuck and broken, and can quickly adjust the position of the entire stack of voucher paper when replacing the voucher paper , so that the paper entering the printer is not easy to tilt and other advantages, it solves the problem that the voucher paper is prone to tilt when it enters the printer, which makes the printed content deviate, and the tear line on the voucher paper has weak structural strength and is easy to be damaged. Jamming and tearing occurred when the paper was fed, causing the printer to break the paper, which in turn affected the printing speed of the chart of accounts and invoices

Abstract

The invention relates to the technical field of printers, and discloses a fast printing device for financial account sheets and invoices, which includes a base and a printer body fixed on the upper end of the base. The upper end of the base is fixedly connected with two support rods, and the upper ends of the two support rods A horizontal plate is fixedly connected together, one end of the horizontal plate is in contact with the printer body, the other end of the horizontal plate is provided with a gap, the opposite sides of the gap are rotatably connected to the transmission shaft through the first rolling bearing, and the upper end of the horizontal plate is rotatably connected to the printer through the rotating shaft. There are two mounting rods, and the opposite sides of the two mounting rods are rotatably connected to the supporting shaft through the second rolling bearing, and the transmission shaft and the shaft wall of the supporting shaft are connected with a transmission mechanism. The financial account sheet and invoice rapid printing device can make the voucher paper feed smoothly without being stuck and broken, and can also quickly adjust the position of the voucher paper when changing the voucher paper, so that the voucher paper entering the printer is not easy to tilt.

Description

technical field [0001] The invention relates to the technical field of printers, in particular to a fast printing device for financial account sheets and invoices. Background technique [0002] The printer is one of the output devices of the computer. It is used to print the computer processing results on the relevant media. There are many types of printers. According to whether the printing element has an impact on the paper, it can be divided into impact printers and non-impact printers. The printing character structure is divided into full-size character printers and dot-matrix character printers. According to the way a line of characters is formed on paper, it is divided into serial printers and line printers. According to the technology used, it is divided into cylindrical, spherical, inkjet, Thermal, laser, electrostatic, magnetic, light-emitting diode and other printers. Financial printers are printing devices specially used to print publications or account sheets. Th...
