Embodiment Construction

[0021] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0022] see Figure 1 to Figure 5 , the present invention provides a technical solution: a small character nozzle frequency conversion separation algorithm, the specific steps are as follows:

[0023] Step 1: Look up the table and send the input point map; the network sinWout (that is, the detection point MP7) is the waveform generated by the host. Specifically, the fixed point map data is transmitted to the host, and the host generates different frequencies according to the data in the point map. Rectangular wave (the general processor can only output rectangular wave), such as image 3 ;

[0024] Step 2: Sine wave generation and correction; after the entire signal passes through the capacitor C191, the DC signal is filtered out to generate a si...

Abstract

The invention provides a small-character nozzle variable-frequency separation algorithm. The small-character nozzle variable-frequency separation algorithm comprises the following specific steps thatan input point diagram is sent through table look-up operation; sine waves are generated and corrected; frequency selection and wave filtering operation are conducted; complementation and amplification are conducted; and pressurization and signal output are conducted. The small-character nozzle variable-frequency separation algorithm is reasonable in design, the purpose that the crystal oscillation frequency of a nozzle is adjustable can be achieved, then the small-character nozzle variable-frequency separation algorithm adapts to different nozzles, different crystal materials, different temperatures and the like, the requirement of a nozzle part device for the material is reduced, and the small-character nozzle variable-frequency separation algorithm can also adapt to different temperatures and is high in environmental adaptation.

Description

technical field [0001] The invention belongs to the technical field of small-character inkjet printers, and in particular relates to a small-character inkjet head frequency conversion separation algorithm. Background technique [0002] The nozzles of the small character inkjet printers currently on the market have the function of amplitude modulation. Through this function, you can adjust the crystal oscillator of the nozzle, and then make the ink line into ink droplets. However, the small character inkjet printers currently on the market have the same crystal oscillator frequency. Due to the difference in material, temperature and humidity, environment, and force characteristics, different crystals and spray guns require different oscillation frequencies, so they are different in manufacturing. The material, temperature, etc., will affect the typing. The small character inkjet printers on the market are all "fixed frequency and amplitude modulation", that is, the oscillati...
