Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a wiping roller cleaning device in an intaglio printing machine, which cleans a dirty wiping roller surface by wiping off excess ink transferred to the intaglio plate surface.

[0002]

[Prior art]

 The conventional wiping roller cleaning device has a cleaning mechanism in which multiple rows of brush units are covered with synthetic fiber non-woven fabric, and a plurality of coil springs mounted inside the frame have an arbitrary cross-sectional shape with elasticity added to the coil springs. It is known that a shaped aggregate is attached, a synthetic fiber non-woven fabric is laid on it, and a synthetic fiber mesh file is further laid on it.

[0003]

[Problems to be solved by the device]

 In the case of a cleaning mechanism in which multiple rows of brush units are covered with synthetic fiber non-woven fabric, the ink wiped off with the wiping roller accumulates on the brush unit, causing clogging of the synthetic fiber non-woven fabric, leading to a decrease in cleaning effect. And the brush unit deteriorates over time due to contact pressure with the wiping roller, which causes serious wear problems, and it is necessary to make the brush shape conform to the surface shape of the wiping roller when replacing the brush unit. There was a drawback that this adjustment took time.

Further, a plurality of coil springs mounted inside the frame are mounted with an aggregate having an arbitrary cross-sectional shape having elasticity, a synthetic fiber non-woven fabric is laid on the aggregate, and a synthetic fiber nonwoven fabric is further synthesized thereon. In the case of a cleaning mechanism formed by stacking fiber mesh files, when the aluminum honeycomb structure was used as a cylindrical aggregate with an arbitrary cross-sectional shape, there was a problem with durability such as corrosion by an alkaline cleaning liquid. .

[0007] Furthermore, the wiping roller surface has a phenomenon in which it is polished by the ink in the process of continuing the wiping, and unevenness is generated in the wiping roller surface shape. Since it does not have the function of following unevenness, it has the drawback that it cannot respond to changes in the surface shape of the wiping roller with time, and that the cleaning effect cannot be maintained stably.

[0006]

[Means for Solving the Problems]

 In order to solve these problems, the present invention provides a base frame in which a cleaning mechanism of a wiping roller cleaning device is installed on a holder having a function of arbitrarily adjusting the tension of the net according to the surface shape of the wiping roller. It is made of a material that has high durability against alkaline aqueous solvents, has openings that do not prevent ink from escaping, and has a moderately flexible net that can withstand any tension. It was mounted with a synthetic fiber mesh file on top of it.

[0007]

[Action]

 With such a configuration, the net can obtain an arbitrary tension, so that it is possible to follow the unevenness of the surface shape of the wiping roller, and it is possible to exhibit the action of appropriately contacting the surface shape of the wiping roller. .

[0008] Furthermore, since the net is very good at removing ink, the ink scraped from the wiping roller is less likely to deposit on the synthetic fiber non-woven fabric, etc., and effectively disperses in the cleaning liquid, resulting in high cleaning. It is possible to exert the function of stably sustaining the effect.

【Example】

 Next, a specific embodiment of the present invention will be described with reference to the drawings, but the present invention is not limited to this. FIG. 1 shows a method of using the wiping roller cleaning device of the present invention. 1 is a wiping roller, 2 is a holder, 3 is a base frame, 4 is a stainless net, 5 is a synthetic fiber non-woven fabric, and 6 is Synthetic fiber mesh file, 7 is a cleaning liquid tank.

To operate this, a holder position adjusting mechanism (not shown) supports the base frame (3) supported by the holder (2), the net (4) made of stainless steel, the nonwoven fabric (5) made of synthetic fiber, and the synthetic fiber made of synthetic fiber. The mesh file (6) is brought into contact with the wiping roller (1) dipped in the cleaning liquid, and the ink adhering to the wiping roller (1) is scraped and dispersed in the cleaning liquid for cleaning.

FIG. 2 shows a structure of a main part (a part for supporting a synthetic fiber non-woven fabric or the like), 4 is a stainless net, 8 is a tension adjusting bolt fixed to the stainless net (3), Reference numeral 3 is a base frame, 2 is a holder, and 9 is a tension adjusting metal fitting fixed to the holder (2).

[0012] Fig. 3 shows a completed figure, in which the base frame (3) is set on the holder (2) and the stainless net (4) is not provided with the tension adjusting bolts (8). After fixing one side of the side to the base frame (3), the tension adjusting bolt (8) is passed through the hole of the tension adjusting metal fitting (9) of the holder (2) and fixed with a nut (not shown).

To operate this, rotate a nut (not shown) meshing with the tension adjusting bolt (8) with a spanner or the like, and use the tension adjusting metal fitting (9) as a fulcrum to move the tension adjusting bolt (8). The tension of the stainless steel net (4) fixed to the tension and tension adjusting bolts (8) is adjusted.

The number of the tension adjusting bolts (8) and the tension adjusting metal fittings (9) is not particularly limited, but in the present invention, it is 13 and the total tension adjusting is partial. It was made possible.

[0015]

【effect】

 As described above, the wiping roller cleaning device of the present invention has a structure that makes it easy to remove ink, has very little clogging, and has the function of easily following irregularities of the wiping roller. There is an advantage that a high cleaning effect can be stably maintained, and there is an advantage that roller wiping does not occur because the wiping roller comes into contact with the wiping roller on its surface while ensuring appropriate flexibility.

[0016] Furthermore, since the ink is removed very well and the synthetic fiber non-woven fabric is less likely to be clogged, the frequency of exchanging the synthetic fiber non-woven fabric is reduced and the net forming the wiping roller cleaning device is Since it has high durability, it is possible to provide a wiping roller cleaning device that can be used semipermanently.
