Technical Field

The utility model relates to a solve inhomogeneous device of gravure printing UV glazing.

Background

With the improvement of the requirements of people on the appearance, the style and the quality of commodity packaging, from design paper to production printing, the process technology is more and more complex, especially the printing is more complex than before, the original single color printing is printed to the subsequent multicolor printing, then the current multicolor superposition printing is printed, or the printing is embodied on the same packaging, and the last color of the printing needs to be glazed with oil to protect the previous printing. The gloss oil also changes from the original oily gloss oil to the subsequent aqueous gloss oil and then to the existing UV gloss oil. The UV glazing oil contains almost no solvent, the emission of organic volatile matters is very little, and the adhesion is firm; the surface of the printed product after UV glazing and curing has the characteristics of more wear resistance, fine film forming, good hand feeling and the like, and the surface looks bright, can almost achieve the mirror effect, is beautiful and has mellow texture, so more and more products are subjected to UV glazing.

The UV gloss of gravure printing also has disadvantages, ink can generate bubbles after being rubbed by a printing plate in a high-speed rotating way, the bubbles cover the surface of the printing plate, so that the UV gloss oil on a printed matter is not uniform, the printed matter is scratched if the bubbles slightly generate fine stripes, and the UV gloss oil on the surface of the printed matter is not coated and blooms seriously, thereby bringing hidden troubles to the product quality.

Detailed Description

The following describes the technical solutions as examples with reference to the accompanying drawings.

1 is a semicircular opening at two ends of an ink groove and is used for installing and fixing a bearing seat of a printing plate; 2 is a newly manufactured ink tank; 3 is an ink returning hole at the bottom of the ink tank 1 and is used for returning the ink to the ink barrel for circulation; 4, a stainless steel ball valve is connected with the ink return hole 3 and used for adjusting the size of the ink return amount; 5 is a stainless steel cylinder which is welded at the bottom of the ink tank 2 and used for installing and fixing a spring 7 and a stainless steel block 6; 6 is a stainless steel block with the thickness of 5mm, which is used for installing and fixing the ink transfer roller 9; 7 are equidistant compression springs for jacking the stainless steel block 6 and simultaneously jacking the ink transfer roller 9 to press tightly on the printing plate 16; 8 is an adjusting nut used for adjusting the up-and-down position of the stainless steel block 6; 9 is an ink transfer roller, a 96-pin water percolation sleeve is sleeved on the roller surface and is used for transferring the ink 15 in the ink tank 2 to a printing plate 16; 10 are bearings at two ends of the ink transfer roller 9, and are used for rotationally connecting the ink transfer roller with the stainless steel block 6 to ensure that the ink transfer roller effectively rotates during working; 11 is a snap ring groove used for fixing the bearing 10 on the shaft at the two ends of the ink transfer roller to ensure that the ink transfer roller does not move axially; 12 is a bearing groove on the stainless steel block 6 and is used for installing and fixing bearings 10 at two ends of the ink transfer roller 9; 13 is a screw hole on the stainless steel block 6, which is used for installing and fixing the stainless steel block 6 on the stainless steel cylinder 5; 14 is a screw thread of the upper end of the stainless steel cylinder 5 for adjusting the up-and-down position of the nut 8.

The method of use is described below:

as shown in fig. 1: newly make an ink groove 2, it is 6mm to weld the diameter at two ends in ink groove bottom, length is four the same stainless steel cylinder 5 of 18mm, will select the same four same equal length compression spring 7 of good cover respectively on same four stainless steel cylinder 5, every compression spring diameter is 8mm, install the stainless steel piece 6 made on stainless steel cylinder 5 according to the position of screw hole again, adjust its upper and lower position through adjusting nut 8, guarantee that ink transfer roller 9 sticiss on galley 16.

As shown in fig. 3: and manufacturing a rubber roller with the diameter of 60mm and the hardness of HS82, installing bearings at two ends of the rubber roller, sleeving the selected 96-pin water percolation sleeve on the rubber roller, sewing the opening of the water percolation sleeve tightly by using a needle thread at the two ends to enable the water percolation sleeve to be tightly attached to the end faces of the two ends of the rubber roller so as to prevent the water percolation sleeve from moving on the rubber roller, and thus, manufacturing the ink transfer roller 9. The prepared ink transfer roller 9 is then mounted on the stainless steel block 6 of the ink tank 2. Thus, a newly manufactured ink tank is well installed and adjusted.

As shown in fig. 4: and adding a proper amount of ink into the ink tank 2 according to the printing technical requirements, wherein the amount of the ink 15 is only required to reach the middle position of the ink transfer roller 9, and the ink return amount of the stainless steel ball valve 4 is adjusted to keep the ink surface of the ink 15 to be always flush with the middle position of the ink transfer roller 9. The fit degree of the ink transfer roller 9 and the printing plate 16 is adjusted by adjusting the screw cap 8, the pressure of the ink transfer roller 9 pressing on the printing plate 16 is moderate, the pressure is too large or too small to affect the printing effect, and the pressure at two ends is consistent, and the pressure at one end cannot be large, but the pressure at the other end cannot be too small. When the printing machine is started to work, the starting gear 19 and the printing plate roller bearing 18 are driven to rotate, the ink 15 is transferred to the printing plate 16 through the ink transfer roller 9, and the image 17 on the printing plate is printed on the paper. Therefore, the phenomenon that the UV glazing is uneven because the printing plate is soaked in the ink and the bubble ink is attached to the printing plate is avoided, and the problem that the printing quality is influenced by the ink bubbles is thoroughly solved.
