Description

Technical Field

[0001] The invention belongs to the technical field of paperless printers, and in particular relates to a high-speed and stable paperless printer. Background Art

[0002] A printer is one of the output devices of a computer. It is used to print the results of computer processing on related media. There are three indicators to measure the quality of a printer: print resolution, print speed and noise. There are many types of printers. According to whether the printing element hits the paper, they are divided into impact printers and non-impact printers. According to the structure of printed characters, they are divided into full-width character printers and dot matrix character printers. According to the way a line of characters is formed on paper, they are divided into serial printers and line printers. According to the technology used, they are divided into cylindrical, spherical, inkjet, thermal, laser, electrostatic, magnetic, light-emitting diode and other printers.

[0003] When in use, common paperless printers are directly connected to the external paper storage area through the paper feed channel, omitting the traditional large-capacity paper bin structure. The paper is introduced from the external paper pile into the internal printing area of ​​the printer one by one by relying on friction and the rotation of the paper feed roller for printing. During this process, the paper is prone to deviation when moving, and the common paper stop mechanism easily causes resistance to the paper, resulting in the paper not being smooth enough when moving and not being able to adapt to different sizes of paper. In view of this, we propose a high-speed and stable paperless printer. Summary of the invention

[0006] In the present technical solution, when in use, personnel can first drive the two paper stoppers to approach each other through the driving assembly according to the width of the label paper. The approach of the two paper stoppers to each other will drive the two support plates to approach each other until the opposite sides of the two paper stoppers are against the two sides of the label paper. At this time, the two paper stoppers can limit the label paper, ensuring that the two paper stoppers can limit the label paper of different widths and ensure that the paper stoppers will not deviate. At the same time, the paper stoppers cancel the upper and lower paper stops and only use the left and right method to stop the paper, so that the label paper will not get stuck during the movement. At the same time, the power component will drive the label paper to move stably. With the cooperation of several first gap sensors, several second gap sensors and paper output sensors, the detection accuracy and sensitivity of the label paper can be improved, so that it can more accurately detect the existence, position and status of the label paper, and timely feedback the label paper information to the printer control system, so as to accurately control the paper feeding process, realize all-round detection of the machine body, and prevent paper feeding problems caused by sensor failure or detection blind spots.
