Abstract

The invention discloses a fountain solution returning and purifying device of a flat paper printer. The fountain solution returning and purifying device of the flat paper printer comprises a box body, wherein an annular pipe is arranged at the upper part of the interior of the box body; through holes are formed in the wall of the annular pipe; one side of the annular pipe is linked with one end of a water inlet pipe; the other end of the water inlet pipe extends out of the box body; a screen plate A and a screen plate B are arranged under the annular pipe in sequence; a screen is arranged on each of the screen plate A and the screen plate B; the screen plate A is horizontally arranged; the screen plate B is obliquely arranged; a precipitation tank is arranged below the screen plate B; an overflow outlet is formed in one side of the precipitation tank; an end cover is arranged at the upper end of the box body and is in hinged connection with one side of the box body; a handle used for opening the end cover is arranged on the end cover. According to the fountain solution returning and purifying device, the fountain solution is buffered by the annular pipe, filtered by the screens and precipitated by the precipitation tank, so that the impurities are filtered and precipitated and the bubbles are also eliminated; the printing quality is ensured.

Description

A kind of flat paper printer fountain solution back-flow scrubbing device

Technical field

The present invention relates to a kind of flat paper printer fountain solution back-flow scrubbing device.

Background technology

Flat paper has printing stock machine; mainly utilize ps plate inherent characteristic, the principle that ink is refused in the water suction of blank portion, areas blotting refuses water, so water conservation blank parts is first gone up in printing; again by ink at areas, carry out indirect branch printing under the effect of the pressure and lead on stock.Fountain solution, mainly to blank parts protection, ensures that blank parts can not have ink to occur, so the quality of fountain solution directly affects printing effect.If fountain solution contains impurity, bubble, control will produce a large amount of scummings, dirty version, print the phenomenons such as unreal.Original printing equipment fountain solution is mainly in damping water tank inner loop, again upper to printing tank, and because the pressure of fountain solution circulating pump is comparatively large, fountain solution is got back to damping water tank by return duct and produced a large amount of bubbles; Alveolate for band fountain solution is drawn into printing equipment by circulating pump again, causes printed matter to have shortcoming like this or phenomenon of biting causes a large amount of waste product, changes fountain solution water so need every day, and each fountain solution of changing needs a large amount of working times and cost.

Summary of the invention

For the deficiencies in the prior art, the present invention aims to provide a kind of flat paper printer fountain solution back-flow scrubbing device, and the impurity in main purpose removing fountain solution and bubble, ensure that the fountain solution quality in print couple, improve printing quality.

For solving the problems of the technologies described above, the technical solution used in the present invention, a kind of flat paper printer fountain solution back-flow scrubbing device, comprise a casing, at casing internal upper part, a ring pipe is set, annular tube wall is provided with through hole, ring pipe side connects with water inlet pipe one end, the water inlet pipe other end stretches out outside casing, in the below of ring pipe, sieve plate A is set, sieve plate A is provided with screen cloth A, the surrounding of sieve plate A is fixed on the sidewall of casing, sieve plate A is the level of state, in the below of sieve plate A, sieve plate B is set, sieve plate B is provided with screen cloth B, sieve plate B is inclined, the lower body of sieve plate B evenly arranges through hole, equally, the surrounding of sieve plate B is fixed on the sidewall of casing, the below of sieve plate B is stillpot, overflow outlet is provided with in the side of stillpot.

The upper end of casing is provided with end cap, and end cap and casing side hinge-coupled, end cap is provided with the handle for opening end cap.

The slanted angle of sieve plate B and horizontal direction is 30 °-60 °.

Adopt technique scheme, fountain solution enters ring pipe from water inlet pipe, fountain solution flows into sieve plate A from the through hole of ring pipe, the flowing pressure that fountain solution produces is eased in ring pipe, the screen cloth A of fountain solution on sieve plate A filters, bubble simultaneously in fountain solution is reduced, fountain solution flows on sieve plate B from sieve plate A again, fountain solution flows slowly further filtration on the screen cloth B of sieve plate B, the stillpot that fountain solution flows into bottom half by the through hole of sieve plate B bottom precipitates again, the impurity contained in such fountain solution is all filtered and precipitates, fountain solution has better quality, fountain solution through filtering and precipitate flows out from overflow outlet, be recycled to forme, higher printing quality can be obtained like this.

Working stability of the present invention is reliable, and maintenance is convenient, and the fountain solution of filtration reaches printing standard.

Detailed description of the invention

Below in conjunction with accompanying drawing, the present invention is further described.

As shown in Figure 1, casing 1 entirety is in cuboid, be made up of metallic plate or plastic plate, the upper end of casing 1 is provided with end cap 9, end cap 9 and casing 1 side hinge-coupled, end cap 9 is provided with the handle 10 for opening end cap 9, at casing 1 internal upper part, a ring pipe 2 is set, ring pipe 2 wall is provided with through hole, ring pipe 2 side connects with water inlet pipe one end, the water inlet pipe other end stretches out outside casing 1 and connects with fountain solution return duct, such fountain solution enters in ring pipe 2, in the below of ring pipe 2, sieve plate A3 is set, sieve plate A3 is provided with screen cloth A4, the surrounding of sieve plate A3 is fixed on the sidewall of casing 1, sieve plate A3 is the level of state, sieve plate A3 is evenly provided with through hole, in the below of sieve plate A3, sieve plate B5 is set, sieve plate B5 is provided with screen cloth B6, the order number of screen cloth B6 is greater than screen cloth A4 order number, sieve plate B5 is inclined, the slanted angle of sieve plate B5 and horizontal direction is 45 °, the lower body of sieve plate B5 evenly arranges through hole, the upper body of sieve plate B5 is entity, the surrounding of sieve plate B5 is fixed on the sidewall of casing 1, the below of sieve plate B5 is stillpot 7, the bottom of so-called stillpot 7 namely casing 1, overflow outlet 8 is provided with in the side of stillpot 7, fountain solution through filtering and eliminate bubble flows out from overflow outlet 8, then forme is delivered to.
