Description
Technical field
Present invention relates particularly to a kind of printing machine damping fluid circulations equipped with transfer water tank.
Background technology
The fountain solution used in offset machine plays the role of cooling, ink-water balance, cleaning version and protection version, makes at present
The damping fluid circulation fouling of offset machine is fairly simple, including water tank, charging pump, sink and siphon device, water inlet
Fountain solution in water tank is delivered in the sink of printing machine by pump, is then back to water tank using siphon device, and whole process is kept
Recurrent state.It has been observed that the offset machine used at present is after a period of use, it may appear that the phenomenon that water dumping (winged water), production
It will appear the region that color is shallower or shows money or valuables one carries unintentionally on product, the checking machine used at present is difficult identification, is not easy to reject, extremely easily be mixed into
Certified products causes serious hidden danger of quality.By technical staff the study found that this is not caused freely by damping fluid circulation return water
, the main reason for damping fluid circulation return water is not smooth is that the subtle ink particle 1) in return water enters water tank, causes water tank
Interior foam is excessive；2) siphon device is easily stifled.It is not smooth in order to solve return water, it needs frequently to clear up water tank and siphon device, seriously affect
Production efficiency.
Invention content
Damping fluid circulation present invention aim to address prior art offset machine is not smooth there are return water, easily
There is the defects of water dumping, a kind of printing machine damping fluid circulation equipped with transfer water tank is provided, set with filter device
Transfer water tank reduces the foam in water tank, easily stifled siphon device is replaced using back water pump, return water is smooth, greatly reduces water dumping.
The present invention is achieved by the following technical solution：
I.e. a kind of printing machine damping fluid circulation equipped with transfer water tank, water tank, sink including composition circulation loop,
Upper hose and return pipe, upper hose are equipped with charging pump, it is characterised in that transfer water tank is additionally provided between return pipe and water tank, in
Turn water tank upper end equipped with case lid, transfer water tank is connected by transfer water pipe and water tank, and return pipe is equipped with back water pump, transfer water pipe
Equipped with transfer water pump, two chambers are divided by filter plate or filter screen inside the transfer water tank, are connect with return pipe
The liquid level detection device being mounted on inner wall is equipped in first chamber, defoaming cover, defoaming are equipped with outside the liquid level detection device
It covers for frame structure, surface is defoaming silk screen.
The present invention substitutes original siphon device using back water pump, solves the defects of siphon device is easily stifled.
Present invention setting transfer water tank, internal setting filter plate or filter screen, can filter the subtle ink in return water
Particle prevents it from entering water tank, causes foam in water tank excessive, while filter plate or filter screen can also play filtering, eliminate
The effect of foam in return water, the foam in anti-non-return water enter water tank.
The liquid level detection device of the present invention is prior art maturation commercial product, is preferably but not limited to sense for photoelectric level
Device, capacitive liquid level sensor.
The liquid level detection device of the present invention is arranged on the top of first chamber inner wall, when the liquid level in first chamber to arrival
When at liquid level detection device, liquid level detection device sends out signal, transfer starting mode of pump, by the fountain solution after being filtered in second chamber
It is transported in water tank, the above process is the good filtration effect of the work of an interval running, filter plate or filter screen.
Foam causes liquid level detection device detection inaccurate in order to prevent, and setting defoaming cover, makes outside liquid level detection device
It obtains foam to cannot be introduced into cover, ensures that level sensing is accurate.
The upper hose of the present invention is inserted into bottom in water tank, and transfer water pipe is inserted into the bottom of first chamber.Upper hose and transfer
Water pipe is inserted into the bottom of corresponding water tank, will not foam be pumped into tubular body easily.
Since damping roller is in rotation status, foam is inevitably will appear in sink, the present invention is equipped with above sink
Scraper plate is defoamed, zigzag is in the scraper plate lower end that defoams, and both ends are equipped with leading screw stent on the outside of sink, and leading screw is mounted on two leading screws
Between stent, leading screw is equipped with screw slider, and defoaming scraper plate is connect by stent with screw slider, one end and the leading screw electricity of leading screw
Machine connects, and slider stroke limit switch is equipped on the inside of two leading screw stents.
The slider stroke limit switch of the present invention is prior art products, when screw slider reaches one of limit switch
When, signal can be sent out, inverts spindle motor, screw slider is made to run back, two limit switch interactions, leading screw
Sliding block drives defoaming scraper plate to do linear reciprocating motion above sink.
The present invention has the advantages that rational in infrastructure, foam is few, return water is smooth.The present invention uses back water pump, in filtering
Turn water tank and the defoaming measure again of scraper plate 3, reduce the foam in the circulatory system, greatly reduce water dumping rate, improve the matter of product
Amount.
