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 uses ps plate inherent characteristic, ink is refused in gutter water suction, areas blotting is refused The principle of water, so printing is first to go up water conservation blank parts, then, is carried out in areas under the effect of the pressure by ink Indirect branch printing is led on stock.Fountain solution mainly protects to blank parts it is ensured that blank parts can not have ink to occur, institute Printing effect is directly affected with the quality of fountain solution.If fountain solution contains impurity, bubble, control will produce substantial amounts of scumming, Dirty version, the printing phenomenon such as unreal.Original printing equipment fountain solution mainly in damping water tank inner loop, above arrives printing water again Groove, because the pressure of fountain solution circulating pump is larger, fountain solution returns to damping water tank by return duct and produces substantial amounts of bubble；Circulation Pump will carry alveolate fountain solution to be drawn into printing equipment again, so leads to printed matter to have shortcoming or phenomenon of biting to cause in a large number Waste product, so needing daily replacing fountain solution water, changing fountain solution every time needs substantial amounts of working time and cost.

Content of the invention

For the deficiencies in the prior art, the present invention is intended to provide a kind of flat paper printer fountain solution back-flow scrubbing device, Main purpose removes impurity in fountain solution and bubble it is ensured that fountain solution quality in print couple, improves printing quality.

For solving above-mentioned technical problem, the technical solution used in the present invention, a kind of flat paper printer fountain solution backflow is net Gasifying device, including a casing, arranges a ring pipe in casing internal upper part, is provided with through hole, ring pipe on annular tube wall Side is coupled with water inlet pipe one end, and the water inlet pipe other end stretches out outside casing, arranges sieve plate a in the lower section of ring pipe, on sieve plate a It is provided with screen cloth a, the surrounding of sieve plate a is fixed on the side wall of casing, and sieve plate a is the level of state, sieve is set in the lower section of sieve plate a Plate b, is provided with screen cloth b on sieve plate b, and sieve plate b is inclined, and the lower body of sieve plate b is uniformly arranged through hole, equally, The surrounding of sieve plate b is fixed on the side wall of casing, and the lower section of sieve plate b is stillpot, the side of stillpot is provided with overflow and goes out Mouthful.

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

Sieve plate b is 30 ° 60 ° with the slanted angle of horizontal direction.

Using technique scheme, fountain solution enters ring pipe from water inlet pipe, and fountain solution flows into sieve from the through hole of ring pipe On plate a, the flowing pressure that fountain solution produces is eased in ring pipe, and fountain solution filters on the screen cloth a on sieve plate a, with When fountain solution in bubble be reduced, fountain solution flows on sieve plate b again from sieve plate a, and fountain solution is enterprising in the screen cloth b of sieve plate b One step unhurried current filters, and fountain solution is precipitated by the stillpot that the through hole of sieve plate b bottom flows into bottom half again, such damping The impurity containing in liquid is all filtered and is precipitated, and fountain solution has better quality, through filtration and precipitate fountain solution from overflow Outlet is flowed out, and is recycled to forme, so can obtain higher printing quality.

The present invention is stable and reliable in work, and maintenance is convenient, and the fountain solution of filtration reaches printing standard.

Specific embodiment

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

As shown in figure 1, casing 1 is overall being made up of metallic plate or plastic plate in cuboid, in the setting of the upper end of casing 1 There are end cap 9, end cap 9 and casing 1 side hinge-coupled, the handle 10 for opening end cap 9 is provided with end cap 9, in casing 1 Internal upper part arranges a ring pipe 2, is provided with through hole, ring pipe 2 side is coupled with water inlet pipe one end, enters on ring pipe 2 wall The water pipe other end is stretched out and is coupled with fountain solution return duct outside casing 1, and such fountain solution enters in ring pipe 2, under ring pipe 2 Side's setting sieve plate a3, is provided with screen cloth a4, the surrounding of sieve plate a3 is fixed on the side wall of casing 1, and sieve plate a3 is on sieve plate a3 Horizontality, sieve plate a3 is evenly arranged with through hole, arranges sieve plate b5 in the lower section of sieve plate a3, is provided with screen cloth on sieve plate b5 The mesh number of b6, screen cloth b6 is more than screen cloth a4 mesh number, and sieve plate b5 is inclined, and sieve plate b5 with the slanted angle of horizontal direction is 45 °, the lower body of sieve plate b5 is uniformly arranged through hole, the upper body of sieve plate b5 is entity, and the surrounding of sieve plate b5 is fixed on On the side wall of casing 1, the lower section of sieve plate b5 is stillpot 7, and the bottom of so-called stillpot 7 namely casing 1, in stillpot 7 Side is provided with overflow outlet 8, through filtering and eliminating the fountain solution of bubble from overflow outlet 8 outflow, is then sent to forme.
