Description

AUTOMATIC PRINTING SYSTEM FOR SILICON AND PRINTING METHOD THEREOF}

The present invention relates to an apparatus for automatically printing silicon on a predetermined width of a textile tape and a method of printing the same, and to enable continuous printing and drying of three or more colors automatically.

In general, silicone printing does not spread on textiles, and prints various trademarks, trade names, or unique symbols and characters so as to protrude clearly, preventing erasing or discoloration by washing, and obtaining a unique advertising effect through three-dimensional expression. Also

In the conventional silicone printing, the screen printing plate of the silk screen is fixed to the printing machine like silk printing, and the fabric tape is disposed below the screen printing plate, and the silicon having a predetermined viscosity spreading the predetermined viscosity with the single color desired by the user is spread on the upper surface of the screen printing plate. When the pressure is slid to the upper surface of the screen printing plate by pressure, the silicon is passed through the screen printing plate to be printed on the upper surface of the fabric tape in the letter or shape engraved on the screen printing plate. In addition, since the printed fabric tape is not dried in the silicon state to move to a separate dryer to dry the silicon to complete the printing.

However, since the printing of silicon is performed by applying silicon on one screen printing plate and pressing the pressing machine, it is impossible to print more than two colors at once, and before the silicon printed on the top of the fabric tape is dried, Because of maintaining fluidity and viscosity, it was not easy to print on the upper surface of the fabric tape once printed.

As a result, conventional silicon printing has conventionally been used to print in a single color, and therefore, its use effect is limited.

The present invention, in order to solve the above problems, a plurality of printing machines and dryers that the screen printing plate is attached and detached is installed in conjunction with the conveyor conveying device for the textile tape is automatically transferred to the printing machine and the dryer to the automatic control By printing and drying it is possible to print a variety of colors of silicon.
