Description
Technical Field
The utility model belongs to the technical field of the inkjet printing, specifically a shower nozzle range structure, shower nozzle mounting panel and printing apparatus.
Background
The existing printing equipment can only print one type of ink in an ink jet mode in the printing process, so that the printed product is not rich enough in color.
Meanwhile, before the surfaces of metal, acrylic, glass and other printing stocks are subjected to ink-jet printing, a layer of pretreatment liquid is firstly coated on the surfaces of the printing stocks in order to increase the adhesive force between the printing ink and the printing stocks, and then ink is jetted. The existing pretreatment liquid has two smearing modes:
1. the pretreatment liquid is manually smeared, and is poured on cotton cloth, and the cotton cloth is held by hands to coat the pretreatment liquid on the surface of a medium to be printed. For example, patent document CN101143983 discloses an ink jet printing ink pretreatment liquid and a manufacturing method thereof, wherein the ink jet printing ink pretreatment liquid has good dispersion stability; low viscosity, uniform coating and strong adhesive force when in use.
However, the pretreatment liquid is a chemical agent, has peculiar smell and is corrosive to a certain extent, so that the smearing mode can affect the health of operators and pollute the working environment of the printer.
2. For example, patent document CN107503197A discloses a white ink pretreatment liquid, a preparation method thereof, and a direct-injection digital printing process, wherein the prepared pretreatment liquid is filled in a sprayer, and the pretreatment liquid is sprayed on a fabric to be treated by the sprayer. For example, patent document CN107236396A discloses a pretreatment liquid for aqueous ink printed artificial leather, which can be sprayed, knife coated, brush coated, and roll coated on the surface of artificial leather, and after coating, can be blown flat by hot air, dried by infrared rays, air dried naturally, or dried by pressing.
However, the spraying method requires more pretreatment liquid than the manual coating method, and the cost is higher.
The prior art can be used for explaining that: the conventional hand segment for coating the pretreatment liquid in the prior art is manually coating the pretreatment liquid or spraying the pretreatment liquid by a spray gun, and the conventional means for curing the pretreatment liquid in the prior art is hot air blowing, infrared drying, natural airing or pressing drying.
In addition, the two methods for applying the pretreatment liquid still have the following defects:
1. generally, an image to be printed is an irregular image, only an approximate printing range can be smeared in a spraying or hand-painting mode, the pretreatment liquid can be smeared on the surface of a printing stock at positions which do not need to be printed, and the surface of the printing stock on which the pretreatment liquid is smeared has marks, so that the printing quality is influenced, and the waste of the pretreatment liquid is also caused;
2. after the pretreatment liquid is smeared on the printing stock in a spraying or hand-painting mode, the pretreatment liquid is required to treat the surface of the printing stock when waiting for a period, so that the adhesive force of the surface of the printing stock is improved, the production efficiency is reduced, meanwhile, the odor pollution is caused to the working environment, and the site cost is increased.
3. The mode of spraying or manually coating the pretreatment liquid needs to be completed manually, and the efficiency is low.
