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: Input the dot map by look-up table method; 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 dot 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 sine wave...

Abstract

The invention provides a small-character nozzle frequency conversion separation algorithm, the specific steps are as follows: look up the table and send the input point map, sine wave generation and correction, frequency selection filter, complementary amplification, boost and signal output, the small character nozzle frequency conversion separation algorithm design Reasonable, it can adjust the crystal oscillation frequency of the nozzle, and then adapt to different nozzles, crystal materials and temperatures, etc., reduce the demand for materials for some components of the nozzle, and can also adapt to different temperatures, and has strong adaptability to the environment.

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, the nozzle crystal oscillator can be adjusted, and then the ink line can be made 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 oscillat...
