Description

Technical Field

[0001] The invention relates to the technical field of printing machines, in particular to a double-sided graphic printing machine with adjustable printing specifications. Background Art

[0002] A double-sided graphic printing press is a highly efficient device upgraded from traditional single-sided printing technology. Its core goal is to simultaneously print graphics on both sides of a substrate (such as paper, film, packaging material) through a one-time or rapid continuous process. Early single-sided printing presses required manual flipping or secondary paper feeding to achieve double-sided printing, which resulted in low efficiency and poor registration accuracy. With the development of digital technology and automated control, modern double-sided printing presses have solved the above bottlenecks through synchronous double-sided printing systems or flip printing architectures.

[0003] For papers of different thicknesses, existing offset printing machines mainly use two methods for adjustment: 1. By adjusting the pad thickness (applicable to smaller size changes); 2. By changing the center distance between the rollers (applicable to larger size changes): By rotating the eccentric sleeve, the position of the roller shaft is changed, thereby changing the center distance between the rollers.

[0004] When adjusting the center distance, it is necessary to gradually adjust the pressure between the upper plate cylinder, the upper rubber cylinder, the lower plate cylinder, and the lower rubber cylinder, and then change the pressure of the water roller and the ink roller. The adjustment steps are cumbersome. After each adjustment, the pressure between the next group of rollers needs to be readjusted according to the adjustment distance, resulting in low adjustment efficiency; and the eccentric sleeve is difficult to adjust and has low accuracy.

[0023] like Figure 2As shown, the upper plate cylinder 13 and the lower plate cylinder 14 are symmetrically arranged, the upper rubber cylinder 11 and the lower rubber cylinder 12 are located between the upper plate cylinder 13 and the lower plate cylinder 14 and are symmetrically arranged, and the total height of the upper rubber cylinder 11 and the lower rubber cylinder 12 is greater than the distance between the upper plate cylinder 13 and the lower plate cylinder 14.

[0024] like Figure 3 As shown, the axes of the upper plate cylinder 13 and the lower plate cylinder 14 are respectively provided with a rotating shaft three 19 and a rotating shaft four 110, the rotating shaft three 19 and the rotating shaft four 110 are rotatably connected to the control box 2, and the control box 2 is equipped with a driving motor 111 for controlling the rotation of the rotating shaft three 19, the rotating shaft three 19 and the rotating shaft four 110 are respectively equipped with a gear one 112 and a gear two 113, the rotating shaft one 17 and the rotating shaft two 18 are respectively equipped with a gear three 114 and a gear four 115, the gear one 112 is meshed with the gear three 114, the gear three 114 is meshed with the gear four 115, and the gear two 113 is meshed with the gear four 115.

[0025] like Figure 1-Figure 4 As shown, the driving motor 111 drives the shaft 17 to rotate, so that the gear 112 on the shaft 17 drives the gear 3 114, the gear 4 115, and the gear 2 113 to rotate in sequence, and then the shaft 17, the shaft 2 18, the shaft 3 19, and the shaft 4 110 rotate synchronously, that is, the upper rubber roller 11, the lower rubber roller 12, the upper printing plate roller 13, and the lower printing plate roller 14 rotate synchronously, and the adjacent two rollers rotate in opposite directions, so that the ink on the upper printing plate roller 13 is printed on the upper rubber roller 11 and then printed on the paper, and the ink on the lower printing plate roller 14 is printed on the lower rubber roller 12 and then printed on the paper.

[0026] The upper plate cylinder 13 and the lower plate cylinder 14 are rotatably mounted on the control box 2 and are fixed in position. When adjusting the center distance, it is only necessary to adjust the pressure between the upper rubber cylinder 11 and the lower rubber cylinder 12, the pressure between the upper rubber cylinder 11 and the upper plate cylinder 13, and the pressure between the lower plate cylinder 14 and the lower rubber cylinder 12. There is no need to move the upper plate cylinder 13 and the lower plate cylinder 14, and the pressure of the water roller 15 and the ink roller 16 can be adjusted, which reduces the complexity of the adjustment and improves the adjustment efficiency.

[0027] Because the upper rubber roller 11 and the lower rubber roller 12 are located between the upper plate roller 13 and the lower plate roller 14 and are symmetrically arranged, the center distance between the upper rubber roller 11 and the lower rubber roller 12 can be changed by moving the upper rubber roller 11 longitudinally. Since the total height of the upper rubber roller 11 and the lower rubber roller 12 is greater than the distance between the upper plate roller 13 and the lower plate roller 14, the center distance between the upper rubber roller 11, the lower rubber roller 12 and the upper plate roller 13, the lower plate roller 14 can be changed by moving the upper rubber roller 11 and the lower rubber roller 12 horizontally.

[0028] During adjustment, firstly, the longitudinal movement of the mounting sleeve 1 25 is controlled by adjusting the second component 4, so as to adjust the center distance between the shaft sleeve 1 27, the rotating shaft 17, the upper rubber roller 11 and the shaft sleeve 28, the rotating shaft 18, and the lower rubber roller 12. Because the mounting sleeve 26 is fixed in the second slider 23, the pressure between the upper rubber roller 11 and the lower rubber roller 12 can be controlled by adjusting the second component 4. The adjustment process is as follows: like Figure 6 , Figure 7 As shown, there are two adjusting components 24, which include a fixed cylinder 21 fixedly connected in the slide groove 21 and a connecting frame 42 arranged on the slider 22, a threaded rod 23 rotatably connected in the connecting frame 42, the threaded rod 23 extends into the fixed cylinder 41 and is threadedly connected to a push rod 24 on the outer side, a bevel gear 3 45 is fixedly installed on the threaded rod 23, a bevel gear 46 is rotatably installed on the connecting frame 42, the bevel gear 3 45 is meshed with the bevel gear 46, and a hexagonal bolt 247 coaxially connected to the bevel gear 46 is installed on the connecting frame 42.

[0029] A push block 48 is slidably connected to the outer side of the push rod 44 , and a spring 49 is sleeved between the push block 48 and the fixed tube 41 on the outer side of the push rod 44 . The push block 48 is located on one side of the mounting sleeve 25 .

[0030] By turning the hexagonal bolts 247 in the two adjusting components 24 with a wrench, the hexagonal bolts 247 drive the bevel gear 46 to rotate, thereby driving the bevel gear 3 45 meshing with the bevel gear 46 to rotate, and then driving the threaded rod 243 to rotate. Because the threaded rod 243 is threadedly connected with the push rod 244, and the push rod 244 is slidably connected in the fixed cylinder 241, the rotation of the threaded rod 243 drives the push rod 244 to move, so that the push block 48 on the push rod 24 is away from the installation sleeve 1 25, thereby releasing the two push blocks. 48 fixes the mounting sleeve 25, and keeps the mounting sleeve 25 stable through the spring 49 between the push block 48 and the fixing cylinder 241, and then the hexagonal bolt 247 in the upper or lower adjusting component 24 is rotated by a wrench, so that the push block 48 on the lower or upper push rod 244 pushes the mounting sleeve 25, so that the mounting sleeve 25 moves longitudinally under the thrust, and then the rotating shaft 17 on the mounting sleeve 25 moves, thereby changing the center distance and pressure between the upper rubber roller 11 and the lower rubber roller 12.

[0031] By rotating the hexagonal bolt 47, the bevel gear 3 45 and the bevel gear 4 46 are driven to rotate, and then the threaded rod 43 is driven to rotate, thereby reducing the displacement of the push rod 44 caused by the rotation of the hexagonal bolt 47, thereby reducing the center distance changed each time the hexagonal bolt 47 is rotated, thereby improving the accuracy of the center distance and pressure adjustment.

[0032] like Figure 5 As shown, a slide rod 29 is fixedly connected to the shaft sleeve 1 27, a slide sleeve 210 is fixedly connected to the shaft sleeve 28, one end of the slide rod 29 passes through the top of the slide sleeve 210 and is slidably connected in the slide sleeve 210, a bottom plate 211 is fixedly connected in the slide sleeve 210, and the side of the bottom plate 211 close to the slide rod 29 is rotatably connected to two clamping plates 212 through a torsion spring, an electric push rod 213 is installed at the bottom of the slide sleeve 210, and a push plate 214 is fixedly connected to the output end of the electric push rod 213, and the push plate 214 is located on the outside of the two clamping plates 212.

[0033] After the adjustment is completed, the electric push rod 213 is started to push the push plate 214 to move upward, so that the push plate 214 pushes the clamping plate 212 along the outer side of the clamping plate 212, so that the two clamping plates 212 rotate close to each other and fit with the sliding rod 29. The inner side of the clamping plate 212 is provided with a latching tooth, and the sliding rod 29 is fixed by the latching tooth, thereby limiting the movement of the sliding rod 29 in the sliding sleeve 210, so that the distance between the shaft sleeve 1 27 and the shaft sleeve 2 28 is fixed, thereby making the center distance and pressure between the upper rubber roller 11 and the lower rubber roller 12 unchanged.

[0034] Then, the hexagonal bolts 2 47 in the two adjusting components 2 4 are rotated by a wrench to move the two push blocks 48 further away from the mounting sleeve 1 25 , thereby releasing the restriction on the mounting sleeve 1 25 . At this time, the distance between the mounting sleeve 1 25 and the mounting sleeve 2 26 remains unchanged.

[0035] like Figure 6 , Figure 7 As shown, the adjustment component 3 includes an empty slot 31 opened on one side of the slide slot 21 of the control box 2 and a fixed cylinder 32 fixedly connected in the slide slot 21, a threaded rod 33 is rotatably connected in the empty slot 31, the threaded rod 33 extends into the fixed cylinder 32 and is threadedly connected to a push rod 34 on the outer side, the push rod 34 is slidably connected in the fixed cylinder 32, and one end of the push rod 34 extends out of the fixed cylinder 32, a bevel gear 35 is fixedly installed on the threaded rod 33, a bevel gear 2 36 is rotatably installed in the empty slot 31, the bevel gear 1 35 is meshed with the bevel gear 2 36, and a hexagonal bolt 37 coaxially connected to the bevel gear 2 36 is installed on the control box 2.

[0036] The two push rods 1 34 in the two adjustment components 1 3 are fixedly connected to the slider 1 22 and the slider 2 23 respectively.

[0037] Then, the slider 1 22 or the slider 2 23 is controlled to move horizontally by adjusting the adjustment component 1 3, so as to adjust the center distance and pressure between the upper rubber cylinder 11 and the upper plate cylinder 13. The adjustment process of the slider 1 22 is as follows: By turning the hexagonal bolt 37 in the adjusting assembly 3 with a wrench, the hexagonal bolt 37 drives the bevel gear 2 36 to rotate, thereby driving the bevel gear 35 meshing with the bevel gear 2 36 to rotate, and then driving the threaded rod 33 to rotate. Because the threaded rod 33 is threadedly connected with the push rod 34, and the push rod 34 is slidably connected in the fixed cylinder 32, the rotation of the threaded rod 33 drives the push rod 34 to move, thereby driving the slider 22 to move, and then driving the rotating shaft 17 on the slider 22 to move, thereby changing the center distance and pressure between the upper rubber roller 11 and the upper printing plate roller 13.

[0038] Similar to the above process, the center distance and pressure between the lower rubber cylinder 12 and the lower plate cylinder 14 are adjusted by the adjustment component 13 at the slider 2 23, thereby completing the adjustment.

[0039] By rotating the hexagonal bolt 37, bevel gear 2 36 and bevel gear 1 35 are driven to rotate, and then the threaded rod 1 33 is driven to rotate, so as to reduce the displacement of the push rod 1 34 caused by the rotation of the hexagonal bolt 1 37, thereby reducing the center distance changed each time the hexagonal bolt 1 37 is rotated, thereby improving the accuracy of the center distance and pressure adjustment.

[0040] like Figure 8 As shown, a protruding rod 38 is provided on the other side of the two slide grooves 21, and a stabilizing block 39 is slidably connected to the outer side of the protruding rod 38. The two stabilizing blocks 39 are respectively located on one side of the slider 1 22 and the slider 2 23. A spring 2 310 is sleeved between the stabilizing block 39 and the slide groove 1 21 on the outer side of the protruding rod 38.

[0041] The spring 2 310 on the protruding rod 38 ensures that the stabilizing block 39 is always in contact with the slider 1 22 or the slider 2 23 , and keeps the slider 1 22 or the slider 2 23 stable when the slider 1 22 or the slider 2 23 is moved or the upper rubber roller 11 or the lower rubber roller 12 is rotated, so as to avoid affecting the printing accuracy.

[0042] It should be noted that, in the process of moving slider 1 22 and slider 2 23, mounting sleeve 1 25 and mounting sleeve 2 26 also move with slider 1 22 and slider 2 23, because the distance between slider 1 22 and slider 2 23 changes, and the distance between mounting sleeve 1 25 and mounting sleeve 26 is limited by sliding rod 29 and sliding sleeve 210, and mounting sleeve 26 is fixed in slider 2 23, so in the process of moving slider 1 22 and slider 2 23, mounting sleeve 26 slides in slider 1 22 as the distance between slider 1 22 and slider 2 23 changes, so as to keep the distance between mounting sleeve 26 and mounting sleeve 2 26 unchanged, thereby keeping the pressure and center distance between the upper rubber roller 11 and the lower rubber roller 12 unchanged.

[0043] It should be noted that, during the movement of the installation sleeve 25, the spring 49 is used to maintain the stability of the installation sleeve 25, and at the same time, the spring 49 is compressed to provide a moving distance for the installation sleeve 25 to move.

[0044] Finally, the hexagonal bolts 47 in the two adjustment components 4 are rotated by a wrench, so that the two push blocks 48 clamp the installation sleeve 25 and completely compress the spring 49 to fix the installation sleeve 25, thereby completing the adjustment.

[0045] Changing the center distance between the rollers by lateral and longitudinal displacement makes pressure regulation more specific and precise.
