Description

Thermal vaporization carbon ribbon, preparation method and printer

Technical Field

The invention relates to the field of printers, in particular to a thermal vaporization carbon ribbon, a preparation method and a printer.

Background

The types of printers commonly found in production and life include mainly inkjet type, laser type, and thermal type. In daily use, inkjet printers are widely used.

The current ink jet printer market is mainly occupied by epressen, hewlett packard and canon. In each large brand of ink-jet printer in the prior art, the specific ink-jet technologies applied are mainly two types: micro-piezo technology represented by epressen, and thermal inkjet technology represented by bubble and hewlett packard thermal technologies.

The main principle of the micro-piezoelectric printer is that the piezoelectric sheet is used for generating mechanical vibration, the whole process of controlling ink jet by the piezoelectric element is completed through pressure, and a nozzle is not required to be heated, so that the printing mode has the advantages of saving energy and prolonging the service life of a printing head; meanwhile, the printer can also accurately control the size and the jetting position of the ink drop, so that the problem of image blurring is avoided; in addition, the requirement for ink selection can be reduced by using the micro-piezoelectric technology, and an ink that chemically reacts at a high temperature can also be used.

However, the greatest disadvantage of piezoelectric ink jet printing is that it is difficult to concentrate a greater number of nozzles on a single printhead, and thus the printing speed is slower. Ink jet print heads made using piezoelectric technology can also be relatively expensive and can be repaired at a relatively high cost in the event of damage. Another disadvantage is that piezoelectric inkjet printing technology wastes a relatively large amount of ink during printing, when a printer nozzle is blocked, a large amount of ink needs to be wasted to clean the nozzle, 30% of ink needs to be wasted to clean the ink head each time the nozzle is replaced, 2-3 minutes of cleaning is needed to start the printer each time, some ink is wasted, and when the air volume sensing device requires a user to replace an ink cartridge, about 20% of ink remains in the ink cartridge.

Thermal inkjet technology, also known as thermal bubble jet technology, relies primarily on electrical resistance to convert electrical energy into thermal energy and provide sufficient heat; the heat of the resistor vaporizes ink near the printer nozzle, and the ink is ejected to print a target image or characters on a printing paper.

However, the ink head using the thermal bubble jet ink jet technology operates in a high-temperature and high-pressure environment for a long time, and the nozzle is easily corroded seriously, and the ink solution is also easy to cause problems such as ink droplet splashing and nozzle clogging.

At present, although the above-mentioned drawbacks can be theoretically optimized to some extent by structural changes or ink improvements, the above-mentioned problems cannot be completely eliminated due to the principle of inkjet printing.

In the prior art, a printer applying thermal printing or transfer printing is provided, which has no ink-jet nozzle structure and ink-jet process, and avoids the problem of ink drying and blocking of the ink-jet printer nozzle, but because the principle of the thermal printer is that a printing head heats and contacts thermal printing paper to realize the printing process, the thermal printing paper is sublimated and attached to a printing stock after chemical reaction through high temperature in the printing process, the printing effect is poor easily caused by the process, and the color is easy to fade and fall off, so that the printing quality is reduced.

Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.

The thermal vaporization carbon ribbon comprises a base material 2, wherein a gas production layer 3, a dye layer 4 and a fusible protective film 5 are sequentially arranged on one side of the base material 2; the gas producing layer 3 can be heated to produce gas; the dye layer 4 can be rapidly melted into a liquid with low viscosity and high fluidity when heated; the fusible protective film 5 can be fused out of the spray holes for spraying the dye of the dye layer 4; when printing, the heat is transmitted by substrate 2, gas production layer 3, dye layer 4 and fusible protection film 5 in proper order, and the gas that gas production layer 3 was heated and is produced provides power for the liquid that dye layer 4 melts, and fusible protection film 5 melts out the orifice, supplies the liquid blowout on dye layer to realize printing.

The thermal vaporization carbon ribbon can comprehensively replace the printing form of the ink-jet printer, thereby avoiding the waste caused by the blockage of a printing nozzle and the cleaning of ink after the blockage of the ink-jet printer.

The thermal vaporization carbon ribbon is a disposable carbon ribbon, and specifically, after a certain point is heated, gas is generated, and the dye layer 4 is melted and sprayed out of the dye, the point can not be printed any more.

The working principle of the thermal vaporization carbon ribbon is that the thermal vaporization carbon ribbon is in non-contact with a printing stock in the printing process, and the dye component of the dye layer 4 is melted into liquid from solid. The difference between the process and the thermal transfer printer in the prior art is that the thermal transfer printer adopts a thermal sublimation thermal transfer ribbon, the thermal sublimation thermal transfer ribbon is in point-to-point contact with a printing stock in the using process, and the dye component of the dye layer is sublimated from solid to gas; the printing process based on point-to-point contact limits the application range of the thermal sublimation carbon ribbon, so that the thermal sublimation carbon ribbon cannot be applied to a wider printing stock, and the thermal transfer printer is not substituted. The thermal vaporization carbon ribbon of the invention not only avoids the problems of ink solidification and waste of the nozzle of the ink-jet printer, but also avoids the problem of limited application range of the thermal transfer printer.

According to the thermal vaporization carbon ribbon, the thickness range of the base material 2 is 4-10 mu m, the thickness range of the gas production layer 3 is 0.2-0.7 mu m, the thickness of the dye layer 4 is 0.7-1.5 mu m, and the thickness range of the fusible protective film 5 is 1.0-2.0 mu m; the thickness range of each layer can ensure the rapid heat transfer and prevent the damage caused by local overheating.

Specifically, if the thickness of the gas generating layer 3 is less than 0.2 μm, the gas generating amount is insufficient, sufficient power cannot be generated to enable the dye layer 4 to be ejected, and if the thickness is more than 0.7 μm, sufficient gas is generated, the dye layer 4 and the fusible protective film 5 cannot obtain sufficient heat, so that sufficient dye cannot be melted out for printing, or the dye cannot be melted out of the nozzle hole in time, and the printing effect is affected; if the thickness of the dye layer 4 is less than 0.7 μm, the printing effect is not clear due to too little dye contained in the dye layer, and if the thickness is more than 1.5 μm, the melting process is too slow, and the gas generated by the gas generation layer 3 cannot effectively form power to the dye layer, so that the printing obstacle is caused; if the thickness of the fusible protection film 5 is less than 1.0 μm, the diameter of the nozzle hole formed by melting is easily larger than the range of fixed point heating, so that the nozzle hole is too large, the printing effect is affected, and if the thickness is more than 2.0 μm, the nozzle hole cannot be formed or too small in time, and the printing process is also adversely affected.

In addition, because the thermal vaporization carbon ribbon is disposable, if printing is not carried out successfully at a certain point, the thermal vaporization carbon ribbon cannot be reused, therefore, the thickness range of each layer can ensure the effective use of the thermal vaporization carbon ribbon, and waste is prevented.

Preferably, the thickness of the gas generating layer 3 is 0.2-0.5 μm, the thickness of the dye layer 4 is 0.7-1.2 μm, and the thickness of the fusible protective film 5 is 1.0-1.5 μm; in practical use, the thickness range of the further preferable layers can ensure that the thermal vaporization carbon tape has good printing effect.
