Printing ink blocking mechanism for preventing ink splashing

Abstract

The utility model discloses a printing ink blocking mechanism for preventing ink splashing, and relates to the technical field of gravure printing machines, including a base, an ink tank fixedly installed on the top of the base, a wedge-shaped mounting block fixedly installed on one side of the ink tank, and a sliding plate slidably installed in the wedge-shaped mounting block. The utility model inserts a spring steel sheet into the sliding plate, and then fixes it by bolts, and then inserts the sliding plate as a whole into the wedge-shaped mounting block, and limits the position by the block, because the spring steel sheet has elasticity, at this time, the upper end of the spring steel sheet contacts the scraper, and when the scraper needs to be adjusted, the spring steel sheet can always contact the lower end of the scraper, and the ink splashed from the ink transfer roller will be blocked by the guide slope of the spring steel sheet, and then flow back into the ink tank through the guide slope, and because the sliding plate is slidably installed on the wedge-shaped mounting block, when the gravure printing machine is stopped, the sliding plate can be slid out as a whole, and then the spring steel sheet can be wiped, and cleaning is also more convenient.

Description

Technical Field

[0001] The utility model relates to the technical field of gravure printing machines, in particular to a printing ink blocking mechanism for preventing ink from splashing. Background Art

[0002] Gravure printing machines are widely used in the field of packaging printing. Gravure printing can truly reproduce the original effect, and has the advantages of rich layers, clarity, thick ink layer, high ink saturation and bright color.

[0003] The gravure ink tanks of existing large gravure printing machines are mostly open structures, so that when the gravure printing equipment is printing at high speed, the ink on the ink transfer roller will be thrown out under the action of centrifugal force, which not only contaminates the surrounding protective gear of the equipment, but also contaminates the printing material, which is not conducive to high-quality production. Utility Model Content

[0004] In order to overcome the above-mentioned defects existing in the prior art, the utility model provides a printing ink blocking mechanism for preventing ink from splashing.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a printing ink blocking mechanism for preventing ink from splashing, comprising a base, an ink tank fixedly installed on the top of the base, a wedge-shaped mounting block fixedly installed on one side of the ink tank, a sliding plate slidably installed in the wedge-shaped mounting block, and a spring steel sheet detachably installed on the top of the sliding plate, and the spring steel sheet is elastic.

[0006] Furthermore, an ink transfer roller is arranged at the upper end of the ink tank, a scraper is arranged at the outer side of the ink transfer roller, and the lower end of the scraper is in contact with the spring steel sheet.

[0007] Furthermore, a guide slope is provided on the right side of the spring steel sheet, and the guide slope is located between the scraper and the ink tank.

[0008] Furthermore, a T-shaped slot is provided inside the wedge-shaped mounting block, a T-shaped block is provided on the right side of the sliding plate, and the T-shaped block is installed in cooperation with the T-shaped slot.

[0009] Furthermore, a stopper is fixedly installed at the rear end of the T-slot, and the stopper is used to limit the installation of the sliding plate.

[0010] Furthermore, the sliding plate is fixed to the lower end of the spring steel sheet by bolts.

[0011] The beneficial effects of the utility model are as follows: the spring steel sheet is inserted into the sliding plate and then fixed by bolts, and then the sliding plate is inserted as a whole into the wedge-shaped mounting block and is limited by the stopper; since the spring steel sheet is elastic, the upper end of the spring steel sheet is in contact with the scraper at this time, and the spring steel sheet can always contact the lower end of the scraper when the scraper needs to be adjusted; the ink splashed out from the ink transfer roller will be blocked by the guide slope of the spring steel sheet and then flow back into the ink tank through the guide slope; and since the sliding plate is slidably mounted on the wedge-shaped mounting block, the sliding plate can be slid out as a whole when the gravure printing machine is stopped, and then the spring steel sheet can be wiped, so cleaning is also relatively convenient.

[0018] In order to more clearly illustrate the technical solution of the utility model, the utility model is further described below in conjunction with the accompanying drawings. Obviously, the accompanying drawings described below are only one embodiment of the utility model. For ordinary technicians in this field, without paying any creative work, other embodiments can be obtained based on this drawing and embodiment, which all belong to the protection scope of the utility model.

[0019] like Figure 1 As shown, the utility model comprises a base 1 , an ink tank 2 is fixedly installed above the base 1 , an ink transfer roller 3 is arranged at the upper end of the ink tank 2 , and a scraper 4 is arranged at the outer side of the ink transfer roller 3 .

[0020] like Figures 1 to 4As shown, a wedge-shaped mounting block 5 is welded and installed on one side of the ink tank 2, and a sliding plate 6 is slidably installed in the wedge-shaped mounting block 5. A T-shaped slot 51 is arranged inside the wedge-shaped mounting block 5, and a T-shaped block 61 is arranged on the right side of the sliding plate 6. The T-shaped block 61 is installed in cooperation with the T-shaped slot 51, and a stop block 52 is fixedly installed at the rear end of the T-shaped slot 51. The stop block 52 is used to limit the installation of the sliding plate 6.

[0021] like Figure 1 and Figure 2 As shown, the sliding plate 6 and the lower end of the spring steel sheet 7 are detachably mounted by bolts 8, the spring steel sheet 7 is elastic, the lower end of the scraper 4 is in contact with the spring steel sheet 7, a guide slope 71 is provided on the right side of the spring steel sheet 7, the guide slope 71 is located between the scraper 4 and the ink tank 2, when the scraper 4 needs to adjust the angle, the spring steel sheet 7 can always contact the lower end of the scraper 4, the ink splashed from the ink transfer roller 3 will be blocked by the guide slope 71 of the spring steel sheet 7, and then flow back into the ink tank 2 through the guide slope 71.

[0022] When the utility model is in use, the spring steel sheet 7 is inserted into the sliding plate 6 and then fixed by the bolt 8, and then the sliding plate 6 is inserted into the wedge-shaped mounting block 5 as a whole, and is limited by the stopper 52.
