Printing device

Abstract

The invention discloses a printing device, comprising a delivery mechanism and a silica gel heater sheet. The delivery mechanism is used to lead a print media into a space between a printing mechanism and a support substrate and lead the print media out of the space between the printing mechanism and the support substrate using rolling of a roller. The silica gel heater sheet is tightly attached on a heating plate, and is used to transmit generated heat to the print media through the heating plate. The support substrate is divided into two parts which are respectively disposed on two sides of the heating plate under the printing mechanism, and the two parts of the support substrate are fixedly connected with two ends of the silica gel heater sheet and two ends of the heating plate. The heating plate and the silica gel heater sheet are disposed under the printing mechanism. The printing device using the silica gel heater sheet can save installation space and is relatively light, thin, short, and small. A size of the printing device can be designed according to a shape of the support substrate. Heating below a print area or heating after printing can reduce drying time of ink, improve printing speed, and solve a problem that paper curls because the paper absorbs the ink and becomes wet.

Description

technical field [0001] The invention relates to a printer, in particular to a printing device heated by a silica gel heating sheet. Background technique [0002] When the user prints a thick pattern and chooses double-sided printing, because the ink is not completely dry after printing, there will be two problems: the image will be polluted by the contact roller; the paper will change its characteristics due to ink absorption, and it is easy to Creates curls. [0003] Such as figure 1 As shown in , a conventional printing device 100 includes a heating lamp 110 , a heating plate 120 , a printing mechanism 130 , a conveying mechanism 140 and a printing medium 150 . Wherein, the heating lamp 110 may be a halogen lamp. The heating plate 120 can be a metal plate with good thermal conductivity. The heating plate 120 is disposed below the printing mechanism 130 and above the heating lamp 110 , and is used for transferring the heat generated by the heating lamp 110 to the printi...

Problems solved by technology

[0002] When the user prints a thick pattern and chooses double-sided printing, because the ink is not completely dry after printing, there will be two problems: the image will be polluted by the contact roller; the paper will change its characteristics due to ink absorption, and it is easy to produce curl

However, the existing printing device 100 is heated by the heating lamp tube 110, the radiation loss is large, and the volume is large, and the printing medium 150 cannot absorb uniform heat.
