Abstract
The utility model provides an offset press dampening device, which is an improvement for the existing single and dual-color offset presses dampening device to adapt the requirement of the alcohol dampening. The dampening device of the utility model comprises a dampening liquid supply box with a pump and a cooling system, and an opening trough arranged below an offset press water roller for containing the dampening liquid; the opening trough is provided with a water inlet, and a water inlet in the same level with the dampening liquid surface; the water inlet and the water outlet are respectively connected with an output terminal and an input terminal of the dampening liquid supply box. The dampening device of the utility model can implement the automatic circulation of the dampening liquid, permanent dampening liquid surface and the stability of the alcohol content, thus ensuring the exactness of the offset and overprint and improving the quality and grade of the printing products.
Description
Technical field
The utility model relates to a kind of offset printing equipment, relates in particular to a kind of dampening device of offset press.
Background technology
Hectographic printing is to utilize the PS version through the trace after the sensitization fountain solution, the different tack of printing ink to be reached printing ink is transferred on the blanket, is transferred on the paper from blanket again.Fountain solution in the past mostly is water or water adds wetting powder, because the volatility of water is relatively poor, and paper needs through repeatedly chromatography, easily produces because of the problem of harmomegathus takes place in suction, thereby influences the degree of accuracy of chromatography.External four colour offset press has adopted alcohol edition-0 moistening at present, promptly adopts and contains certain density alcohol water blend as fountain solution.Because the volatility of alcohol is good, use the alcohol water blend damping, the moisture on the PS version is reduced greatly, improve the percent reduction of site, thereby improved the definition of inking part.In addition,, the suction of paper is reduced, avoided paper to produce the harmomegathus problem that absorbs water, guaranteed the degree of accuracy of chromatography because of chromatography repeatedly because space of a whole page water content reduces.Single, double look offset press on the market still adopts water or water to add wetting powder as fountain solution at present, its dampening device mostly is a rectangle tank that places water rod below, fountain solution adopts artificial addition manner, promptly when liquid level drops to certain limit in the tank, manually it is filled it up with.Because liquid level is from manually filling it up with to dropping to certain limit in the tank, space of a whole page water content is also descending, and the content of fountain solution in printing process can not keep stable, causes the quality of offset product instability, and the error of chromatography is big.So the dampening device of existing single, double look offset press can not adapt to the needs of alcohol edition-0 moistening.And adopt the dampening device complex structure of the four colour offset press of alcohol edition-0 moistening abroad, involve great expense.
Summary of the invention
The purpose of this utility model is the improvement to existing single, double look offset dampening device, provides a kind of simple in structure, fountain solution circulation automatically, temperature stabilization, damping liquid level can keep constant dampening device, makes it can adapt to the needs of alcohol edition-0 moistening.
For achieving the above object, dampening device of the present utility model comprises the fountain solution service tank that has pump and cooling system, places offset press water rod below to be used for the open trough of splendid attire fountain solution; This open trough have water inlet, with the delivery port that the damping liquid level maintains an equal level, this water inlet, delivery port are connected with output, the input of above-mentioned fountain solution service tank.
When making fountain solution enter open trough, can keep the temperature unanimity from an end of open trough to the other end, the top of above-mentioned water inlet is connected with a small-bore pipe that is parallel to liquid level, and some apertures are arranged at this pipe top, and other end sealing.
For making fountain solution can flow into the damping liquid level equably, in the water inlet and the delivery port centre of open trough one dividing plate is arranged, this dividing plate is a little more than delivery port.
For the ease of the cleaning of open trough, above-mentioned open trough bottom is cleaned discharge outlet in addition.
In order to increase back-flow velocity, when guaranteeing that the fountain solution admission velocity is big, can in time discharge, also for convenience of the deposition of impurity in the fountain solution, above-mentioned delivery port and cleaning discharge outlet are infundibulate.
In order to guarantee that the fountain solution temperature is not because of ectocine changes in the whole open trough, above-mentioned open trough outer wall is lined with a heat-insulation layer.
Use dampening device of the present utility model, can realize that fountain solution circulates automatically, the constant and fountain solution temperature of damping liquid level stable, thus make the content of alcohol in the fountain solution can remain unanimity, guarantee the accuracy of offset printing chromatography, improved the quality and the class of printing.In addition,, make printing process reach ink-water balance very soon, thereby reduce of the waste of school machine, help reducing cost with paper because the turnover of fountain solution is even.

Fig. 1 is single, double look offset press ink route schematic diagram.
Fig. 2 is the vertical view of the utility model dampening device open trough.
Fig. 3 is the profile of Fig. 1 along the A-A line.
Specific embodiment
As shown in Figure 1, 2, 3, establish a rectangular open trough 5 below the damping roller 6 of offset press, water inlet 1 is offered in open trough 5 bottoms, delivery port 2, cleaning discharge outlet 3, water inlet is connected with the output of fountain solution service tank, and delivery port is connected with the input of fountain solution service tank.Water inlet 1 is to be formed by connecting by two sections mutually perpendicular water pipes, and long that section water pipe is parallel with liquid level, and its other end sealing, and the top of this water pipe has row's aperture 7; Delivery port 2 height maintain an equal level with the damping liquid level, are the maintenance mouths of a river of circulation liquid level, and are even for making water outlet, respectively establish one at the open trough two ends, are infundibulate; Cleaning discharge outlet 3 maintains an equal level with the open trough bottom surface, also is infundibulate, and during operate as normal, this discharge outlet is closed.In the middle of water inlet and delivery port a dividing plate 8 is set, this dividing plate height is a little more than the height of delivery port, and purpose is to make fountain solution can enter the damping liquid level uniformly.In order to make fountain solution in the open trough, also be lined with a heat-insulation layer of making by asbestos at the outer wall of open trough not because of the ectocine temperature changes.
During offset press work, the fountain solution that the fountain solution service tank will contain alcohol by pump is sent into the heat exchanger in the cooling system, after heat exchanger cools off fountain solution, import fountain solutions through water inlet 1 to open trough 5 by output, fountain solution overflows from the aperture 7 of water pipe end face, when liquid level reaches the height of dividing plate 8, fountain solution covers this dividing plate gradually, enter the damping part, when the liquid level of damping part reaches the height of delivery port 2, fountain solution enters the fountain solution service tank by delivery port 2 through the input of fountain solution service tank, by being pumped into the cooling system cooling, forms whole circulation again.
