Problems solved by technology

[0004] Traditional curing uses high-pressure mercury lamps or metal halide lamps, which can cure the ink well and give full play to the ink's best adhesion, hard blocking and other properties, but it has the disadvantages of high heat generation, inability to switch frequently, and large volume
But in some cases, these disadvantages make it impossible to place it behind the spray head to control the spread
[0005] Ultraviolet LED lamps are suitable for controlling spreading. It makes up for the shortcomings of the above-mentioned traditional light sources, but under the existing technical conditions, its narrow spectral distribution and low light intensity do not match well for some inks. At this time not fully cured

Embodiment Construction

[0017] The gist of the present invention is to overcome the deficiencies of the prior art, and provide an inkjet printing curing device and its operation method, which combines pre-curing and final curing, first curing with LED to control its spreading, and only curing the surface layer of the spray film to ensure printing accuracy ; Then the high-pressure mercury lamp or metal halide lamp will fully cure it to ensure the performance of the ink.

[0018] The following will describe in detail with reference to the accompanying drawings in conjunction with the embodiments, so as to further explain the technical features and advantages of the present invention.

[0019] The structural principle of the present invention is as figure 1 As shown, an ink jet printing curing device includes a conveyor belt 4, a printing substrate 3 is placed above the conveyor belt 4, and a nozzle 1, a pre-curing device 2 and Final curing device 5. The pre-curing device 2 is an ultraviolet LED curin...

Abstract

The invention discloses an ink jet-printing curing device, which comprises a conveyor belt. A print base material is arranged on the conveyor belt; a nozzle, a pre-curing device and a final curing device are arranged above the print base material from left to right in turn; the pre-curing device is an ultraviolet light-emitting diode (LED) curing lamp with the wavelength ranging from 280 to 410 nanometers; a distance between the ultraviolet LED curing lamp and the nozzle is adjustable in a range of 2-30 centimeters; LED chips are arranged in the ultraviolet LED curing lamp; the power of a single LED chip is 2-12 watts; the LED chips are densely arranged to form a line source or a surface source; and the final curing device is a high pressure mercury lamp or a metal halid lamp. By combining the operating method for the curing device, the surface of ink can be effectively cured, the ink is prevented from penetrating the base material and flowing on the base material, positions of ink spots are fixed, the morphology is controlled, the compatibility with ink types is improved, and defects that heat productivity is high, switch-on and switch-off cannot be frequently carried out, and a volume is large are overcome.

Description

technical field [0001] The invention relates to an LED curing device, which is mainly used for ink jet printing curing in the PCB industry and inkjet industry, in particular to an ink jet printing curing device and an operation method thereof. Background technique [0002] In recent years, UV-curable inks for inkjet printing have been continuously developed, and have been widely used in inkjet printers and photo printers. At the same time, they have also developed in the field of PCB character printing. After the ink is cured, in order to obtain good printing quality by printing UV-curable ink, it is necessary to control the flow of ink droplets sprayed onto the substrate, and a light-curing device is used after the nozzle. [0003] Photocuring has two points: control spreading, ink flow and impregnation on the substrate, proper curing can shape its position and shape, which is necessary in occasions where high printing precision is required; curing effect makes the ink dry,...
