Description

Ink supply device for large format printers {ink supply a feeder for intelligent printer}

The present invention relates to an ink supply device for a large printer, and more particularly, to supply ink to the head uniformly, continuously, and stably without replacing a cartridge in a large-format printing printer such as large-scale due diligence and wide color. And it relates to an ink supply device for a large printer with improved economics.

Due to the recent development of the industry, due to environmental beautification and the need for advertisement, large-scale due diligence, wide color, and large banners are widely used. The demand for printers is inevitably increasing.

As described above, the conventional ink supply apparatus for large-format printers is provided with respective cartridges injecting a plurality of different colors of ink so as to supply various colors, thereby supplying ink of a required color and amount to a head for ejecting ink.

However, in the conventional ink supply apparatus as described above, when the printed matter is larger, the ink of the cartridge is exhausted during printing, so the output must be paused, the cartridge must be paused, the print job must be resumed, and the print job must be resumed. In addition to environmental pollution and monetary loss due to replacement, it affects the printing state of the printed matter, which is accompanied by a problem of degrading the print quality due to the enormous disruption to the print quality.

In order to compensate for these problems, the ink is continuously supplied by inserting ink into a constant container which is easy to put ink and easy to store, but in order to supply ink in the container to the head to maintain a constant water pressure and injection amount It consists of a sense, a pump, etc. to ensure a smooth supply, and installs power and circuits to drive it. However, it is difficult to install due to the volume and weight of the supply device due to the additional installation of mechanical devices. In addition, although additional financial and spatial problems arise due to additional financial expenses of installation and maintenance costs, related companies are not able to suggest appropriate solutions.

Therefore, the present invention has a fine filter having a wider filter area than the injection tube of the injection hose which injects ink from the ink container for storing the ink to the head for injecting the ink onto the printing paper. It consists of a damper that is supplied at a constant pressure when the ink in the ink bottle is injected into the head, and filters out impurities in the ink and prevents banding due to the lack of ink even in long time output, so it is stable by constant ink injection of the head. It is composed of technical problems with the focus on making it possible to produce high quality large-format prints at low cost by facilitating efficient and easy printing.

A conventional large-scale print supplying ink to a head 20 having a jet nozzle for injecting ink onto an output paper through a connection hose 3 to a plurality of ink containers 2 into which ink of different colors and colors are injected, respectively. An ink supply apparatus for a device;

Inside the injection device 1 composed of a head 20 for injecting ink and a board 30 for adjusting the injection amount and the injection time, a micro filter 11 is installed in the center to maintain an area of a predetermined width. The furnace forms a collecting tank 13 to secure a certain amount of ink, and a damper 10 forming an agglomeration tank 12 in which impurities filtered by the fine filter 11 are agglomerated at the top thereof, and connects hoses to upper and lower end faces. It is a structure in which the ink in the ink container 2 is supplied to the head 20 through the connecting portions 14 and 14 'by protruding the connecting portions 14 and 14' connecting the head 3 and the head 20, respectively. .

The ink supply apparatus for a large printer, which may be configured as described above, may be configured by forming a damper 10 configured in the injection apparatus as shown in FIG.

That is, the water collecting tank 13 which maintains a certain space in the center is formed in the shape of the hopper which the lower part becomes narrow, and the seat hole 11a and the female screw 19 are formed in the upper part, respectively, and the head 20 and the lower part of the water collecting tank 13 are formed. A water collecting pipe 16 protruding the connecting portion 14 'which is easy to connect is formed, and a connecting hose 3 which transfers and supplies ink to the upper center portion, and an easy connecting portion 14 protruding from the lower outer diameter. A cover 15 is formed to form a male screw 18 and a coagulation tank 12 having a lower portion open at the center thereof, and the micro filter 11 and the O-ring 17 are seated in the seating holes 11a, respectively. It is the structure of the damper 10 comprised by fastening the male screw 18 of the cover 15 to the female screw 19 of (16).

As in the conventional large-format printer injector 1, when the ink is sprayed through the injection nozzle of the head 20 in accordance with the color and the injection quantity to be output by the board 30, the amount of ink to be injected is connected in the ink container 2. It is injected through the hose (3).

At this time, impurities present in the ink block the injection nozzle of the head 20 so that the normal amount of ink is not ejected or the pressure required for the ink to come to the head 20 is insufficient. Cases frequently occur.

Accordingly, the dampers 10 configured as in the present invention are seated inside the injection apparatus 1 as shown in FIG. 1, so that the respective inks 2a, 2b, and 2c have different colors in the plurality of ink containers 2. In the state of injecting the respective connecting hoses (3) to each of the damper (10) connected to the connection portion 14 mounted on the injection device (1) consisting of a plurality, the head 20 is connected to the connection portion 14 ' The ink is injected from the head 20 according to the color and the injection amount set by the board 30 so that the ink embedded in the sump 13 of the damper 10 is transferred to the printing paper through the injection nozzle of the head 20. As the ink is injected, the ink is supplied due to the vacuum pressure inside the damper due to the injection pressure of the head 20 because a predetermined amount of ink is always embedded in the damper 10.

As a result, a certain amount of ink sprayed through the spray nozzle of the head 20 is suddenly ejected by the spray nozzle of the head 20 and is collected in the sump 13 located near the head 20 even though a large amount of ink is rapidly consumed. The ink contained in the ink container 2 is transferred to the damper 10 at the injection pressure due to the injection pressure of the head 20 by the injection pressure of the head 20.
