Abstract
The utility model relates to a steam fog dampening device for an offset press. One side of a plate roller of an offset press is provided with a dampening cover which is communicated with a liquid storage box, and a steam fog generator is arranged in the liquid storage box. The utility model carries out dampening through the vaporisation of dampening liquid and by the self-rotation of the plate roller. The utility model does not directly contact the plate roller. Thus, the structure of the offset press is simplified, the abrasion of the plate roller is reduced, and the quality of dampening is good so that the water and ink of the plate roller is more balanced. Thereby, the utility model further improves the quality of planographic printing.
Description
The utility model relates to a kind of offset press steam fog dampening device, is the improvement to existing offset press;
Lithographic offset printing has levels are rich, tone is soft, and chromatography is accurate, the characteristics that cost is low.In the lithographic offset printing process, need the version roller of offset press is carried out damping and inking, by damping to the version roller, make the blank parts on the forme maintain layer of even damping liquid film, could guarantee normally carrying out and obtaining superior printing quality of printing.The dampening device of existing offset press is by formations such as water (fountain solution) case, damping roller, biography damping roller, dampening vibrator rollers, its structure is comparatively complicated, in the damping process between the damping roller part, between damping roller and the version roller, be in contact with one another to produce and wear and tear, not only reduce the service life of each roller, also can influence lithographic quality.
The purpose of this utility model be to provide a kind of fountain solution evenly is attached on edition roller and not with the contacted offset press steam fog of version roller dampening device.
The purpose of this utility model is realized by following technical scheme: the side at printing machine version roller 8 is provided with plate moistening cover 3, and plate moistening cover is connected with fluid storage tank 5, is installed on the steam fog generator in fluid storage tank.
According to such scheme, main feature of the present utility model is to have adopted the steam fog generator, fountain solution is vaporized into tiny and uniform gas, enter plate moistening cover, because the outlet of plate moistening cover is facing to the version roller,, make the fountain solution of steam fog shape directly be adsorbed on an edition roller surface equably, thereby reach the purpose of the version roller being carried out damping from the negative pressure that air-flow produces and the eddy current that when work is rotated, form by the version roller.The utility model has following advantage: one, dampening device directly do not contact with the version roller, have reduced the wearing and tearing of version roller, improve its service life; Its two, the fountain solution after the vaporization is attached on edition roller, is easy to form the damping liquid film that is evenly distributed, the damping quality is good, and lithographic quality is further enhanced; Three, the structure of steam fog dampening device is simple relatively, has simplified the structure of whole offset press, and simultaneously, the degree of fountain solution being adhered to edition roller also is easier to control.
Fig. 1 is the structure chart of an embodiment of the utility model.
Fig. 2 is the structure chart of another embodiment of the utility model
First embodiment of the present utility model as shown in Figure 1, has a roller 8, side at the version roller is equipped with some ink rollers 9, ink roller contacts with the version roller and rotates in opposite directions, be used for to printing ink on the version roller 1 and supply printing ink, install the plate moistening cover 3 that has arc opening at the opposite side of version roller, the arc opening of plate moistening cover is facing to the version roller, press close to version roller surface, be connected with a balanced device 4 in the rear end of plate moistening cover, can make fountain solution gas 2 density that spill out more even like this, balanced device is connected with tank, is installed on a supersonic generator 7 in the fluid storage tank, as the steam fog generator, deposited fountain solution in the fluid storage tank, also be installed on an automatic liquid supply device 6 and be connected, be used for fountain solution is in time compensated with fluid storage tank.
Second embodiment of the present utility model as shown in Figure 2, the difference of it and a last embodiment is to install in the fluid storage tank heater 12 and disposes agitating device 11, constitute the steam fog generator, by heating and stirring fountain solution is vaporized rapidly and uniformly, the heating-up temperature of fountain solution is usually above room temperature 40-60 ℃, the higher fountain solution of temperature can condense into liquid film rapidly and be attached on edition roller after running into the lower version roller of temperature, present embodiment also can be provided with balanced device 4, and the structure of other parts is identical with a last embodiment.
