Problems solved by technology

[0003] Existing thermal printers cannot directly print double pages, and the printed documents can only be single sheets, which cannot meet the needs of double pages or multiple pages
Moreover, thermal paper must be used to print, which is costly. When printing with thermal paper, it is easy to cause problems such as different printing shades, single color, and printed documents cannot be stored permanently.

Embodiment 1

[0060] When it is necessary to use ordinary paper for single-sided printing, the first sorter selects the paper storage tank containing ordinary paper, and sends the paper to the conveying device, and the paper feeder of the conveying device sends it to the printing platform. The paper feeder and the output device work together to stretch and lay the paper flat; at this time, the printing core starts to work, and the printing data is converted into bitmap data through the control board, and then the vibration focuser on the printing core is controlled according to the points of the bitmap data Through the current, through the accelerometer sensor, the natural frequency of the molecule can be detected for different papers passing through the sorter, and the detected structure is fed back to the control board of the printer head, and the same frequency as the molecular natural frequency of ordinary paper is selected to work , the distance sensor cooperates with the horizontal adj...

Embodiment 2

[0062] When it is necessary to use double-sided printing, through the first sorter, select the paper storage tank containing ordinary paper or select suitable paper, and send the paper to the conveying device, and the paper feeder of the conveying device is sent to the printing table. When the paper feeder and paper output device work together, the paper is stretched and paved; at this time, the printing core starts to work, and the printing data is converted into bitmap data through the control board, and then the vibration on the printing core is controlled according to the points of the bitmap data The focuser can detect the molecular natural frequency of different papers passing through the sorter through the current and the accelerometer sensor. The detected structure is fed back to the control board of the printer head, and the appropriate frequency is selected for work. The distance sensor cooperates with the level The adjuster and the vertical adjustment motor adjust th...

Embodiment 3

[0064] When it is necessary to use color thermal paper for printing, the first sorter selects the color thermal paper in the paper storage tank and sends it to the conveying device, and the paper feeder of the conveying device is sent to the printing table. Work with the paper output device to stretch and lay the paper; at this time, the printing core starts to work, converts the printing data into bitmap data through the control board, and then controls the vibration focuser on the printing core to pass current according to the points of the bitmap data , through the accelerometer sensor, it is possible to detect the molecular natural frequency of different papers passing through the sorter, and the detected structure is fed back to the control board of the printer head to select the content of the thermal sensitive material on the surface of the color thermal paper. The three molecular natural frequencies of the RGB pigment microcapsules are switched at the same frequency; th...

Abstract

The invention relates to a thermal printer. The thermal printer comprises a shell, a printer core, a plurality of paper containing troughs, a conveying device and a printing table, wherein the printing core, the paper containing troughs, the conveying device and the printing table are arranged inside the shell. The printer core comprises a horizontal regulator, a base plate, a controller, an adjusting plate, a heat dissipation plate, a plurality of vibrating focalizers, a distance inductor and two vertical regulating motors, wherein the horizontal regulator, the base plate, the controller, theadjusting plate, the heat dissipation plate and the vibrating focalizers are arranged from top to bottom in sequence. The distance inductor is arranged on the lateral side of the base plate. The twovertical regulating motors are arranged on the two sides of the horizontal regulator correspondingly. The key idea of the thermal printer is that by using the vibrating focalizers, vibration waves ofdifferent frequencies are generated by the vibrating focalizers, vibration printing can be conducted according to the specific vibration frequency of an object, simultaneous printing of a plurality oflayers of paper can be achieved, and thus, dual-connected and multi-connected printing of the thermal printer can be achieved.

Description

technical field [0001] The invention relates to the technical field of printers, in particular to a thermal printer. Background technique [0002] The working principle of a thermal printer is that a semiconductor heating element is installed on the print head. After the print head is heated and contacts the thermal printing paper, the required pattern can be printed out. Its principle is similar to that of a thermal fax machine. The image is created by applying heat, which creates a chemical reaction in the film. This thermal printer chemical reaction is carried out at a certain temperature. High temperatures accelerate this chemical reaction. When the temperature is lower than 60°C, it takes quite a long time, even several years, for the paper to become dark; and when the temperature is 200°C, this reaction will be completed within a few microseconds. [0003] Existing thermal printers cannot directly print double pages, and the printed documents can only be single shee...
