Abstract

The utility model relates to a piston type vacuum storage container for offset ink, which comprises a thin-wall cylinder body and a piston positioned in the cylinder body, wherein the front end of the cylinder body is provided with an ink discharging opening and a sealing cover covering on the ink discharging opening. The container has convenient transportation, and the ink can not leak due to the fact that the container is horizontally arranged or tilted or reversed in the transportation process and the loading and unloading process. The sealing performance is good, the ink preservation time is long, therefore the ink can not be wasted. The use is convenient, and the mechanical ink extruding method or the pneumatic ink extruding method can be utilized. Moreover, the utility model has the advantages of simple structure, low cost and convenient operation.

Description

The piston type vacuum stores offset ink container

Technical field

The utility model relates to the packing and storing ink supply apparatus of offset ink, specifically, relates to a kind of piston type vacuum and stores offset ink container.

Background technology

In the offset printing industry, traditional offset ink container, the circular iron flask of black sheet iron compacting is generally adopted in its packing and storage, and it is made up of tank body and loam cake two parts, after filling out printing ink, hides with plastic film on the surface of printing ink, and lid again closes.This packing, storing mode have following four defectives:

1, transportation is inconvenient.In transportation and handling procedure, can only keep flat, otherwise can spill printing ink because of tilting or being inverted;

2, because of skinning even the dry ink quality that influences.Printing ink and plastic film sealing periphery be because of sealing bad air and the printing ink Long contact time chemically reactive of making in the black sheet iron jar, the easy skinning in printing ink top layer, and long even printing ink of time one dries up, and can reduce ink quality, and cause great waste;

3 when using, and printing ink scraped with scraper by manual, therefore be difficult to printing ink in the jar is got totally, always some ink adhesion plastic film sealing cover with tank skin in, the general loss that causes because of adhesion is about 8%;

4 get, ink supply labour intensity is big, especially winter, temperature is low, ink viscosity increases, operation is difficulty especially.

Occur at present a kind of and the matching used offset ink plastic containers of the full-automatic ink-feeding device of pulse induction on the international market, back down the elasticity cover printing ink mouthful gap of conforming to the principle of simplicity is flowed out thereby this container promotes the printing ink reach by piston under pressure.This device has following defective:

1, this container and the supporting use of pulse induction automatic ink-supply equipment, and this apparatus structure complexity costs an arm and a leg, the user is difficult to bear, and can't promote;

2, this container cartridge mouth structure complexity, the cost height has increased product cost;

3, required air pressure height, consumption gas is big, backs down container cover because of moving forward by printing ink, and air pressure needs more than 5kg, consumes so high air pressure for a long time, and printing machine self is caused deficiency with gas;

4, bottleneck ink outlet port footpath is little, and resistance is big, and it is little to go out the China ink amount, and it is long to add the China ink time, inefficiency;

5, nozzle complex structure, it is unclean to go out China ink, and residual ink amount hinge is many, and tube port position can lose 2% printing ink.

The utility model content

The purpose of this utility model is to overcome above-mentioned defective, provides a kind of oil-collecting China ink packing, vacuum to store one, gets China ink piston type vacuum storage easily offset ink container.

Piston type vacuum described in the utility model stores the container of offset ink, and convenient transportation can not spill printing ink because of keeping flat in the transportation and handling procedure, tilt or being inverted; Good seal performance, vacuum stores, and printing ink is skinning not, and the holding time is long, and it is clean to get China ink, can not cause the waste of printing ink; Easy to use, can adopt and use machinery or the pneumatic printing ink of extruding, and simple in structure, cost is low, and is easy to use, the efficient height.

Description of drawings

Fig. 1 is the structural representation that piston type vacuum described in the utility model stores offset ink container;

Fig. 2 is an A-A profile among Fig. 1.

The specific embodiment

Referring to Fig. 1, piston type vacuum described in the utility model stores the container of offset ink, comprises thin-walled simplified 2 and is positioned at simplified piston 1, and the front end of cylindrical shell 2 is provided with printing ink discharging mouth 3 and lid seal cover 4 thereon.When in the ink tank of offset press, adding printing ink, piston to be exerted pressure, piston is moved by the rear end forward end of tube, is about to printing ink and extrudes in cylindrical shell through the discharging mouth.

An embodiment of described piston is that its front end has the intermediate projections 5 that matches with the discharging mouth 3 of cylindrical shell 2, so that printing ink is all extruded from cylindrical shell 2.Piston shown in dotted lines in Figure 1 is represented printing ink is extruded substantially fully.

Another embodiment of described piston is that the longitudinal axis section of piston 1 is the not convex shape of back cover of lower end, and the shape of its upper end projection 5 matches with simplified discharging mouth.

The outer surface of described intermediate projections has 2-4 groove 6, the printing ink between the upper surface of piston end surface and cylindrical shell all can be extruded.

Claims

1, the piston type vacuum stores the container of offset ink, it is characterized in that the piston (1) that comprises thin-wall barrel (2) and be positioned at cylindrical shell, the front end of cylindrical shell (2) are provided with printing ink discharging mouth (3) and cover thereon seal cover (4).

2, container according to claim 1 is characterized in that the front end of described piston (1) has the intermediate projections (5) that matches with the discharging mouth (3) of cylindrical shell (2).

3, device according to claim 1, the longitudinal axis section that it is characterized in that described piston (1) are the not convex shape of back cover of lower end, and the shape of its upper end projection (5) matches with the discharging mouth of cylindrical shell.

4,, it is characterized in that the outer surface of described intermediate projections has 2-4 groove (6) according to claim 1,2 or 3 described devices.
