Problems solved by technology

However, if the newly added wetting device is listed separately, it will lead to too many instruments required for the printing-erasing cycle, which will lead to the problems that the device occupies a large space and is not suitable for carrying.

Embodiment 1

[0028] The wetting device and the printing device are the same part, and a commercial foaming inkjet printer is used as the printing device, and pure water is injected into the matching empty ink cartridge as the liquid used for printing and wetting, so as to base on the printed pattern And / or text water-induced color dye water writing paper is the substrate that needs to be erased. Input and / or draw the area that needs to be wetted in the computer for printing, and the substrate that is wetted in the corresponding area can be obtained. Then, through the resistance heating of the printer itself, the blank can be printed again to realize the rapid volatilization of the liquid, so that the patterns and / or characters on the water writing paper disappear, and the water writing paper can be reused.

Embodiment 2

[0030] The wetting-heating device is two independent devices for wetting and heating, and the wetting device in the two independent devices for wetting and heating refers to a process that is carried out by the same numerical control method as the printing device and the heating device. Controlled, including a container containing a developer and a device connected with it to inject the developer into a device capable of liquid coating on a substrate; the container containing the developer and the The connection refers to the connection with a catheter.

[0031] A commercial piezoelectric inkjet printer 1 is used as a printing device, a plastic box filled with pure water is used as a container 3, and a conduit 4 is connected to a wetting brush 8, and water is continuously injected into the wetting brush 8 through digital control through pressure. On the brush 8, use the water-writing paper based on the hydrochromic dye that has been printed with patterns and / or characters as t...

Embodiment 3

[0033]The wetting-heating device is two independent devices of wetting and heating, and the wetting device in the two independent devices of wetting and heating refers to that one and the printing device and the heating device are carried out by the same numerical control method. Controlled, including the container containing the color developer and the device connected with it to inject the color developer into the liquid coating on the substrate by the action of force.

[0034] A commercial piezoelectric inkjet printer 1 is used as a printing device, and weakly acidic water is injected into the matching empty ink cartridge as a liquid for printing, and a plastic box filled with weakly acidic water is used as a container 3, and the wetting belt is directly connected to the plastic box The solution in it is connected, and the water is continuously poured onto the wetting belt 5 by gravity, and the water writing paper based on the hydrochromic dye that has been printed with patt...

Abstract

The invention relates to an inkless printer for reusing water-written paper, including a commercial inkjet printing device, and a device installed in the inkjet printing device for quickly erasing the text displayed on the rewritable substrate and / or patterned wetting and heating devices. The invention has the functions of wetting and heating for quickly erasing the characters and / or patterns displayed on the rewritable and rewritable substrate, thereby achieving the purposes of cost saving and convenient use.

Description

technical field [0001] The invention belongs to the technical field of printing, and in particular relates to an inkless printer for reusing water writing paper. Background technique [0002] The dwindling of the earth's resources and the increasingly severe ecological problems have prompted the vigorous development of reusable paper, especially the reusable water writing paper that changes color when exposed to water, because it uses clean, green, and convenient water as a stimulus, and only It needs to be filled with water instead of ink in the ink cartridge to achieve the display of patterns and / or characters comparable to traditional printing. Once published, it has attracted widespread attention (Nature Communications, 2014, 5, 3044), among which the supporting The inkless printer has applied for a related invention patent (CN 103434270B). For reusable paper with short-term retention of writing and / or patterns after water writing or water jet printing, the printed writ...
