Problems solved by technology

[0002] The printer is an indispensable tool in the home or work. The paper feeding device of the printers on the market now lays the paper flat, and the paper is introduced by the paper transfer wheel inside the printer for work. However, due to the static electricity between the papers, the paper is too thin , unevenness and other problems, printers often enter two or more sheets of paper at a time, and paper jams will occur, causing great inconvenience and wasting paper. Existing printers are generally set to single-roller printing, and printers often Paper jams can greatly reduce the life of the printer and are expensive to repair

Embodiment 1

[0015] Example 1, see figure 1 , Fig. 3, a kind of double-roller printer, described printer comprises machine box body body 1, paper input device 6, paper output device 2, paper output tray 5, and described paper input device 6 is positioned at described machine box body 1 bottom , the opening of the paper feeding device 6 is rectangular, the paper feeding device 6 communicates with the inside of the machine box body 1, and the paper output device 2 is located at the top of the machine box body 1 and communicates with the inside of the machine box body 1, so The paper output tray 5 is located below the paper input device 6 , and the printer also includes a double-roller locking device, and the double-roller locking device is arranged outside the machine box body 1 .

[0016] The double-stick locking device mainly completes the process of transferring paper. In the process of transferring paper, the double-stick locking device ensures the smooth process of paper, thereby avoidi...

Embodiment 2

[0017] Example 2, see figure 1 , figure 2 , as an improvement of the present invention, the double-roller locking device includes a paper feeding roller 4 and a paper receiving roller 10 , and a conveying belt 11 is provided outside the paper feeding roller 4 and the paper receiving roller 10 .

[0018] The paper feeding roller transfers the paper to the paper receiving roller. Since the transmission is through the conveyor belt, the transmission in the middle is relatively stable, and the paper is not easy to be tilted, distorted, etc. during the transmission process.

[0019] The rest of the structures and advantages are exactly the same as in Embodiment 1.

Embodiment 3

[0020] Example 3, see figure 1 , figure 2 , as an improvement of the present invention, the printer also includes a paper support board, the paper support board is composed of a vertical board 3 and a horizontal board 7, and the vertical board 3 and the horizontal board 7 are connected in an "L" shape, close to the vertical board The paper feed roller is installed at the position, and a motor is housed in the paper feed roller, and the motor drives the paper feed roller and then drives the paper receiving roller to move.

[0021] The rest of the structures and advantages are exactly the same as in Embodiment 1.

Abstract

The invention relates to a double-roller printer. The double-roller printer is characterized by comprising a machine box main body, a paper feeding device, a paper discharging device and a paper discharging support, wherein the paper feeding device is positioned at the lower part of the machine box main body; an opening of the paper feeding device is rectangular in shape; the paper feeding device is communicated with the interior of the machine box main body; the paper discharging device is positioned at the upper part of the machine box main body, and is communicated with the interior of the machine box main body; the paper discharging support is positioned below the paper discharging device; the printer further comprises a double-roller locking device; and the double-roller locking device is arranged outside the machine box main body. Compared with the prior art, the double-roller printer has the following advantages: (1) the whole structural design is skilful and reasonable; and the double-roller locking device is arranged to solve the problem of frequent paper jam in the prior art; (2) the service life of the printer is greatly prolonged; and the maintenance cost is reduced; (3) the printer has high working efficiency, saves the paper resource, and is in favor of the environmental protection; and (4) the double-roller printer is lower in cost, and is convenient for large-scale promotion and application.

Description

technical field [0001] The invention relates to a printer, especially a double-roller printer. Background technique [0002] The printer is an indispensable tool in the home or work. The paper feeding device of the printers on the market now lays the paper flat, and the paper is introduced by the paper transfer wheel inside the printer for work. However, due to the static electricity between the papers, the paper is too thin , unevenness and other problems, printers often enter two or more sheets of paper at a time, and paper jams will occur, causing great inconvenience and wasting paper. Existing printers are generally set to single-roller printing, and printers often Paper jams can greatly reduce the life of the printer and be expensive to repair. Therefore, there is an urgent need for a new technical solution to solve the above problems. Contents of the invention [0003] The present invention provides a double-roller printer aimed at the technical problems existing ...
