The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
An ink splashing prevention device as shown in fig. 1 to 4 comprises a first clamping plate 11, a separation plate 12, a second clamping plate 13, a connecting plate 15 and a mounting plate 16, wherein the separation plate 12 is mounted between the first clamping plate 11 and the second clamping plate 13, one end of the connecting plate 15 is connected with the first clamping plate 11, and the other end of the connecting plate 15 is connected with the mounting plate 16. The first clamping plate 11 and the second clamping plate 13 are both arc-shaped plates. The radian of the first clamping plate 11 is matched with that of the second clamping plate 13. Round holes 14 are formed in the first clamping plate 11, the isolation plate 12 and the second clamping plate 13, and bolts 6 are installed in the round holes 14. The mounting plate 16 is a plate material with a groove-shaped cross section, and the mounting plate 16 is provided with an adjusting groove 161. The width of the isolation plate 12 is greater than that of the first clamping plate 11, and the width of the isolation plate 12 is greater than that of the second clamping plate 13. The connecting plate 15 is vertically arranged, and one end of the first clamping plate 11 is connected with the connecting plate 15 through welding or gluing, and one end of the mounting plate 16 is connected with the connecting plate 15 through welding or gluing. First splint 11, division board 12 and second press from both sides the round hole 14 of seting up and all be in same position, and division board 12 passes through 6 clamps of bolt between first splint 11 and second splint 13, and division board 12 chooses for use soft PVC transparent soft plastics, and division board 12 assembly back warp into with the cambered surface of the camber of first splint 11 and second splint 13 looks adaptation. The mounting plate 16 is mounted at the edge of the ink tank 2 so that the spacer 12 is closely above the plate cylinder 3, and ink thrown off by the plate cylinder 3 is well blocked by the spacer 12 to prevent the ink from splashing on the paper 4. The mounting portion is provided with an adjustment groove 161, and the horizontal distance between the partition plate 12 and the plate cylinder 3 can be adjusted by the adjustment groove 161, thereby adjusting the amount of shading.
The main components of the ink are a polymerizable prepolymer, a photosensitive monomer and a photoinitiator, and the auxiliary components are a coloring pigment, a filler, an additive (a leveling agent, a polymerization inhibitor) and the like. Because printing ink has certain corrosivity, the aluminium alloy material corrodes through the printing ink of throwing away and produces impurity such as aluminium oxide, and these impurity fall into printing ink tank 2 in will pollute printing ink, influence printing effect, and the iron material corrodes through the printing ink of throwing away and produces the iron rust, and the same reason also can influence printing effect, and stainless steel material has corrosion resistance, consequently stainless steel material is chooseed for use to first splint 11 and second splint 13. The division board 12 is made of PVC transparent soft plastic, the PVC transparent soft plastic is good in bending property, and is deformed to an ideal bending degree after being locked by the bolts 6, and the printing plate is convenient to observe.
An intaglio printing press as shown in fig. 5 to 7 is mainly composed of a paper feeding unit, an inking unit, a printing unit, and a drying unit. The paper conveying device consists of a paper separating mechanism, a conveying device, a positioning device and a paper transferring device. The paper 4 is separated by the paper separating head, conveyed to the front gauge position through the paper conveying plate, and conveyed to the paper nipping toothed belt of the impression cylinder 5 by the paper transferring teeth after the side gauge position, so as to finish printing. The inking unit consists of an ink tank 2 and a doctor blade. During printing, the plate cylinder 3 is immersed in the ink tank 2, and then the ink on the blank part of the plate is scraped by the doctor blade, so that the ink on the image and text part is transferred to the paper 4 to finish printing. The printing device consists of a plate cylinder 3, an impression cylinder 5, a clutch pressure mechanism and a pressure regulating mechanism. The impression cylinder 5 is brought into contact with the plate cylinder 3 to complete printing, and the printed sheet 4 is delivered to a drying device for drying.
The intaglio printing press further comprises the ink throwing prevention device, and the ink throwing prevention devices 1 are respectively arranged on two sides of the ink tank 2. The ink throwing prevention device 1 is fixed on the ink tank 2 through a claw screw 7, and a separation plate 12 of the ink throwing prevention device 1 is positioned above the plate cylinder 3 and is 5-15mm away from the plate cylinder 3. The claw screw 7 has the advantage of being free from tool mounting and dismounting, and the claw screw 7 is adopted to fasten the adjusting groove 161 of the ink throwing prevention device 1, so that the position of the ink throwing prevention device 1 can be quickly adjusted. To ensure the effectiveness of the barrier against ink and to avoid wear of the plate cylinder 3, the distance of the spacer 12 from the plate cylinder 3 should be controlled between 5 and 15 mm.
The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
