Description

Technical Field

[0001] This utility model relates to the field of offset printing machine technology, and in particular to an intelligent inking device for a five-color offset printing machine. Background Technology

[0002] Offset printing presses are a common type of planographic printing equipment, specifically designed for large-format printing tasks. It is a widely used printing technology in commercial printing today. Offset printing presses transfer images and text from the printing plate to a blanket cylinder through indirect printing, and the blanket cylinder then transfers the image to paper or other printing media. The working principle of offset printing presses is based on the immiscibility of oil and water. Its working steps include paperboard preparation, water application, inking, transfer, and printing. In the inking process, ink is transferred to the printing plate via an ink roller system. The image areas on the printing plate absorb ink, while the hydrophilic areas repel it, thus the ink adheres only to the image and text areas. The inking system of an offset printing press is a crucial part of the entire printing process; it is responsible for evenly transferring ink to the printing plate to ensure the quality and consistency of the printed image. The inking system typically consists of a series of rollers and control devices that can precisely control the supply and distribution of ink to meet the needs of different printing tasks. The inking system generally consists of an ink fountain, ink fountain roller, ink fountain blade, inking transfer roller, inking distribution roller, and ink application roller.

[0003] However, in existing offset printing presses, the ink transfer roller, ink distribution roller, and ink application roller are all fixedly and rotatably mounted on the frame. The gaps between the ink transfer roller, ink distribution roller, and ink application roller generally need to be manually disassembled and adjusted, which makes the equipment setup inconvenient and time-consuming, thus affecting production efficiency. Utility Model Content

[0004] Therefore, it is necessary to provide an intelligent inking device for a five-color offset printing press to address the technical problems of inconvenient manual adjustment and low efficiency of existing offset printing press inking devices.

[0005] An intelligent inking device for a five-color offset printing press includes a frame, an inking supply component, an inking distribution component, and an inking component. The inking supply component, the inking distribution component, and the inking component are all mounted on the frame, and the side surfaces of the inking supply component, the inking distribution component, and the inking component are sequentially engaged and abutted against each other.

[0006] The frame includes a first adjustment mechanism and a second adjustment mechanism. The first adjustment mechanism is disposed at both ends of the ink distribution component to adjust the relative position between the ink distribution component and the frame. The second adjustment mechanism is disposed at both ends of the ink application component to adjust the relative position between the ink application component and the frame.

[0007] In one embodiment, the ink supply assembly includes an ink supply roller and a height adjustment assembly. The height adjustment assembly is disposed on opposite side wall surfaces inside the frame, and both ends of the ink supply roller are connected to the height adjustment assembly.

[0008] In one embodiment, the height adjustment assembly includes two mounting seats with grooves and two limiting members. The two mounting seats are disposed opposite to each other on the side wall surface inside the frame. The rotating shafts at both ends of the ink supply roller are connected to the grooves of the two mounting seats. The two limiting members are engaged with the grooves of the mounting seats and abut against the rotating shaft side surface of the corresponding ink supply roller.

[0009] In one embodiment, the above-mentioned ink distribution assembly includes an ink transfer roller and two ink distribution rollers, all of which are rotatably mounted on the frame. The ink transfer roller is correspondingly disposed and abuts against the side surface of the ink supply roller; the two ink distribution rollers abut against the ink transfer roller in sequence.

[0010] In one embodiment, the first adjustment mechanism includes a first ink distribution adjustment seat and a second ink distribution adjustment seat. The first ink distribution adjustment seat and the second ink distribution adjustment seat are respectively disposed on the frame corresponding to the two ink distribution rollers. The first ink distribution adjustment seat is disposed on the side closer to the ink transfer roller, and the second ink distribution adjustment seat is disposed on the side farther away from the ink transfer roller.

[0011] In one embodiment, both the first ink distribution adjustment seat and the second ink distribution adjustment seat are movable and fitted onto the frame.

[0012] In one embodiment, the first ink distribution adjustment seat includes a first mounting seat, a fixed seat, and an adjustment component. The fixed seat is fixedly mounted on the frame, the first mounting seat is engaged with the rotating shafts at both ends of the corresponding ink distribution roller, and the first mounting seat is movably connected to the fixed seat through the adjustment component.

[0013] In one embodiment, the second ink distribution adjustment seat includes a second mounting base and a drive cylinder. The drive cylinder is fixedly mounted on the frame, the second mounting base is engaged with the rotating shafts at both ends of the corresponding ink distribution roller, and the output end of the drive cylinder drives and connects to the second mounting base.

[0014] In one embodiment, the first ink-equalizing adjustment seat further includes a connector, one end of which is connected to the first mounting base, and the other end of which abuts against the second mounting base.

[0015] In one embodiment, the inking assembly includes two inking rollers, which sequentially abut against the ink transfer roller.

[0016] In one embodiment, the second adjustment mechanism includes a first ink adjustment seat and a second ink adjustment seat, which are respectively disposed on the frame corresponding to the two ink rollers. The first ink adjustment seat is disposed on the side closer to the ink transfer roller, and the second ink adjustment seat is disposed on the side farther away from the ink transfer roller.

[0017] In one embodiment, the first ink-adjusting seat and the first ink-uniforming adjusting seat are configured as a mirror image.

[0018] In one embodiment, the second ink adjustment seat and the second ink distribution adjustment seat are configured as a mirror image.

[0019] The aforementioned intelligent inking device for a five-color offset printing press uses an inking supply component to quantitatively transfer ink from the ink fountain to the inking distribution component. The inking distribution component then uses rolling, pressing, and axial sliding actions to form a uniform ink layer of a preset thickness, which is then transferred to the inking component and printed onto the blanket, thus completing the inking process. The frame includes a first adjustment mechanism and a second adjustment mechanism. The first adjustment mechanism is located at both ends of the inking distribution component to adjust the relative position between the component and the frame, thereby achieving adaptive adjustment of the ink distribution gap. The second adjustment mechanism is located at both ends of the inking component to adjust the relative position between the component and the frame, thereby achieving adaptive adjustment of the inking gap. In practical applications, the first and second adjustment mechanisms work together to effectively control the ink delivery gap between the inking distribution component and the inking component, enabling the inking device to intelligently adjust the output ink thickness. This significantly improves the precision control of the ink layer thickness and uniformity, thereby improving the printing effect. Attached Figure Description

[0027] Please see Figures 1 to 3 This utility model discloses an intelligent inking device for a five-color offset printing press. The intelligent inking device for the five-color offset printing press includes a frame 100, an inking supply component 200, an inking distribution component 300, and an inking assembly 400. The inking supply component 200, the inking distribution component 300, and the inking assembly 400 are all mounted on the frame 100. The side surfaces of the inking supply component 200, the inking distribution component 300, and the inking assembly 400 are sequentially engaged and abutted against each other. Thus, the inking supply component 200 is used to quantitatively transfer ink from the ink fountain to the inking distribution component 300. Then, the inking distribution component 300 forms a uniform ink layer of a preset thickness through rolling, pressing, and axial sliding of the ink, and then transfers it to the inking assembly 400 for printing onto the blanket, thereby completing the inking work of the offset printing press. Specifically, the frame 100 includes a first adjustment mechanism and a second adjustment mechanism. The first adjustment mechanism is correspondingly disposed at both ends of the ink distribution component 300 to adjust the relative position between the ink distribution component 300 and the frame 100, thereby achieving adaptive adjustment of the ink distribution gap of the ink distribution component 300. The second adjustment mechanism is correspondingly disposed at both ends of the inking component 400 to adjust the relative position between the inking component 400 and the frame 100, thereby achieving adaptive adjustment of the inking gap of the inking component 400. In practical applications, the first adjustment mechanism, in conjunction with the second adjustment mechanism, can effectively control the ink delivery gap between the ink distribution component 300 and the inking component 400, thereby enabling the inking device of this invention to intelligently adjust the thickness of the output ink, thus greatly improving the precise control of the ink layer thickness and uniformity of the inking device, thereby improving the printing effect of the product.

[0028] Furthermore, the ink supply assembly 200 includes an ink supply roller 210 and a height adjustment assembly 220. The height adjustment assembly 220 is disposed on opposite side wall surfaces inside the frame 100. Both ends of the ink supply roller 210 are connected to the height adjustment assembly 220, thereby enabling the height adjustment assembly 220 to adaptively adjust the setting height of the ink supply roller 210 relative to the frame 100. Specifically, the height adjustment assembly 220 includes two lifting seats 221 with sliding grooves and two limiting members 222. The two lifting seats 221 are disposed opposite each other on the side wall surfaces inside the frame 100. The rotating shafts at both ends of the ink supply roller 210 are connected to the sliding grooves of the two lifting seats 221. The two limiting members 222 are engaged with the sliding grooves of the lifting seats 221 and abut against the rotating shaft side surfaces of the corresponding ink supply roller 210, thereby achieving adaptive adjustment of the setting height of the ink supply roller 210 relative to the frame 100.

[0029] Furthermore, the ink distribution assembly 300 includes an ink transfer roller 310 and two ink distribution rollers 320. The ink transfer roller 310 and the two ink distribution rollers 320 are rotatably mounted on the frame 100. The ink transfer roller 310 is correspondingly arranged and abuts against the side surface of the ink supply roller 210. The two ink distribution rollers 320 abut against the ink transfer roller 310 in sequence. Thus, the ink supply roller 210 can transfer ink to the side surface of the ink transfer roller 310. The two ink distribution rollers 320 can adjust and control the thickness and uniformity of the ink layer on the surface of the ink transfer roller 310 by abutting against each other in sequence.

[0030] Furthermore, the first adjustment mechanism includes a first ink distribution adjustment seat 110 and a second ink distribution adjustment seat 120. The first ink distribution adjustment seat 110 and the second ink distribution adjustment seat 120 are respectively disposed on the frame 100 corresponding to the two ink distribution rollers 320. The first ink distribution adjustment seat 110 is disposed on the side closer to the ink transfer roller 310, and the second ink distribution adjustment seat 120 is disposed on the side farther from the ink transfer roller 310. Specifically, both the first ink distribution adjustment seat 110 and the second ink distribution adjustment seat 120 are movably fitted to the frame 100, thereby allowing the two ink distribution rollers 320 to adjust their position relative to the frame 100 through the corresponding first ink distribution adjustment seat 110 and second ink distribution adjustment seat 120, thus achieving adjustment of the gap between the ink distribution roller 320 and the ink transfer roller 310.

[0031] Furthermore, the first ink distribution adjustment seat 110 includes a first mounting seat 111, a fixed seat 112, and an adjustment component 113. The fixed seat 112 is fixedly mounted on the frame 100. The first mounting seat 111 is engaged with the rotating shafts at both ends of the corresponding ink distribution roller 320. The first mounting seat 111 is movably connected to the fixed seat 112 through the adjustment component 113, so that the corresponding ink distribution roller 320 can be moved and adjusted relative to the fixed seat 112 within a preset range through the first mounting seat 111 and the adjustment component 113.

[0032] Furthermore, the second ink distribution adjustment seat 120 includes a second mounting seat 121 and a drive cylinder 112. The drive cylinder 112 is fixedly mounted on the frame 100. The second mounting seat 121 is engaged with the rotating shafts at both ends of the corresponding ink distribution roller 320. The output end of the drive cylinder 112 is connected to the second mounting seat 121, so that the drive cylinder 112 can drive the corresponding ink distribution roller 320 to move and adjust relative to the frame 100 within a preset range through the second mounting seat 121.

[0033] Furthermore, the first ink distribution adjustment seat 110 also includes a connector 114. One end of the connector 114 is connected to the first mounting seat 111, and the other end of the connector 114 abuts against the second mounting seat 121. Thus, when the drive cylinder 112 drives the second mounting seat 121 to move, the connector 114 can drive the first mounting seat 111 to move and adjust relative to the fixed seat 112 within a preset range, thereby realizing the linkage adjustment between the two ink distribution rollers 320 and the ink transfer roller 310.

[0034] Furthermore, the inking assembly 400 includes two inking rollers 410, which sequentially abut against the ink transfer roller 310. Thus, when the ink distribution roller 320 adjusts the ink layer on the surface of the ink transfer roller 310 to a preset thickness and uniformity, the two inking rollers 410 sequentially obtain a preset amount of ink from the surface of the ink transfer roller 310, thereby completing the inking process on the corresponding blanket.

[0035] Furthermore, the second adjustment mechanism includes a first inking adjustment seat 130 and a second inking adjustment seat 140. The first inking adjustment seat 130 and the second inking adjustment seat 140 are respectively disposed on the frame 100 corresponding to the two inking rollers 410. The first inking adjustment seat 130 is disposed on the side closer to the inking roller 310, and the second inking adjustment seat 140 is disposed on the side farther from the inking roller 310. Specifically, the first inking adjustment seat 130 and the first inking evenness adjustment seat 110 are mirror images of each other, and the second inking adjustment seat 140 and the second inking evenness adjustment seat 120 are mirror images of each other; further details will not be elaborated here.

[0036] In summary, the intelligent inking device for a five-color offset printing press disclosed in this utility model quantitatively transfers ink from the ink fountain to the ink distribution component through the ink supply component. The ink distribution component then forms a uniform ink layer of a preset thickness through rolling, pressing, and axial sliding actions, which is then transferred to the inking component for printing onto the blanket, thus completing the inking process of the offset printing press. The frame includes a first adjustment mechanism and a second adjustment mechanism. The first adjustment mechanism is correspondingly disposed at both ends of the ink distribution component to adjust the relative position between the ink distribution component and the frame, thereby achieving adaptive adjustment of the ink distribution gap of the ink distribution component. The second adjustment mechanism is correspondingly disposed at both ends of the inking component to adjust the relative position between the inking component and the frame, thereby achieving adaptive adjustment of the inking gap of the inking component. In practical applications, the first adjustment mechanism, together with the second adjustment mechanism, can effectively control the ink delivery gap between the ink distribution component and the inking component, thereby enabling the inking device of this invention to intelligently adjust the thickness of the output ink, which greatly improves the precise control of the ink layer thickness and uniformity of the inking device, thus improving the printing effect of the product.
