Drying device of inkjet printer

Abstract

The invention discloses a drying device of an inkjet printer. The drying device comprises a drying base, a drying shell, a support rod, a drying lamp, a cabinet door and a rubber mat, the drying shell is arranged on the upper side of the drying base, a drying chamber is arranged inside the drying shell, a drying platform is arranged inside the drying chamber, a corona wire and an anode plate are installed on two sides of an inner wall of the drying chamber, the support rod is arranged on one side of the upper end of the drying base, a cross rod is arranged on the upper end of the support rod, the drying lamp is arranged on the lower side of the cross rod through a lampshade, supporting feet are arranged on the four corners of the lower side of the drying base, the cabinet door is connected with one side of the drying base in a hinged mode, and the support rod is composed of a first telescopic rod and a second telescopic rod. According to the drying device of the inkjet printer, the corona wire and the anode plate are arranged on the two sides of the inner wall of the drying chamber, electrostatic dust removal can be carried out while drying, dust is prevented from sticking on a printed paper, and the printing effect is affected.

Description

technical field [0001] The invention belongs to the technical field of inkjet drying equipment, in particular to a dryer for inkjet printers. Background technique [0002] Inkjet printers can be divided into solid inkjet and liquid inkjet according to the working principle (now the latter is more common), and the liquid inkjet method can be divided into bubble type and liquid piezoelectric type. Bubble technology is to heat the nozzle to make the ink generate bubbles and spray it onto the printing medium. Thermal induction inkjet technology uses a thin film resistor to heat less than 0.5% of the ink in the ink ejection area to form a bubble. This bubble expands extremely fast (less than 10 microseconds), forcing the ink droplet out of the nozzle. The bubble continues to grow for a few microseconds before disappearing back onto the resistor. When the bubbles disappear, the ink in the nozzle is retracted. Surface tension then creates a suction force that pulls new ink to r...

Problems solved by technology

Under the situation of fierce competition in the photo and inkjet industry, the research and development of domestic and foreign photo machine and inkjet machine manufacturers focus on the high speed, high precision and stability of the machine, but greatly neglect the problem of how to dry the high-speed output screen, making The scrap rate in printing is getting lower and lower, but the scrap rate of the output screen is extremely high, and the problem of sticking ink, mucous film, and sticking dust caused by the screen is prominent

[0003] The drying technology of the existing inkjet printer has the following problems: the drying technology of the existing inkjet printer cannot remove dust when drying, and the dust is easy to stick to the printing paper, which easily affects the printing effect and is inconvenient to carry out. Adjust the degree of drying, the use of flexibility is low
