Description

Technical Field

[0001] The invention relates to the technical field of gravure printing, in particular to a processing technology and processing equipment for gravure printing paper of ink. Background Art

[0002] Ink gravure printing refers to a printing roller with set patterned concave dots on its surface that absorbs ink in the ink grooves, and then cooperates with an extrusion roller to squeeze the printing paper between the printing roller and the extrusion roller, thereby printing the ink in the concave dots onto the paper.

[0003] At present, the existing ink needs to absorb the ink in the ink tank, so the conventional design is that the printing roller is at the bottom and the extrusion roller is at the top, which causes the pattern to be printed at the bottom when the paper is transmitted between the two rollers. Due to the quality of the ink or the thickness of the printed pattern, some printed patterns are not completely dry after printing, which makes the pattern prone to defects such as adhesion when it is subsequently rolled up. For this reason, we propose a processing technology and processing equipment for gravure printing paper with ink. Summary of the invention

[0029] Example 1

[0030] See also Figure 1-Figure 4 , a processing device for gravure printing paper of an ink shown in the figure, comprises an ink tank 1, a printing roller 2 and an extrusion roller 3, the printing roller 2 is rotatably installed in the ink tank 1, and also comprises a steering roller 4 installed on one side of the ink tank 1, two driving rods 5 are installed between the steering roller 4 and the ink tank 1, and one end of the steering roller 4 is connected to the driving device, the outer ends of the two driving rods 5 are fixed with driving gears 6, and the outer ends of the two driving rods 5 are sleeved with toothed belts 7 meshing with the driving gears 6, the outer end of the steering roller 4 is installed with a linkage 8 connected with one of the driving rods 5, a plurality of mounting seats 9 are equidistantly installed on the toothed belt 7, and a blowing component 10 is installed between the adjacent mounting seats 9 of the two toothed belts 7;

[0031] It should be noted that by designing a toothed belt 7 and a plurality of air blowing components 10 on the outside of the ink tank 1, the ink just printed can be directly blown to make the ink dry quickly.

[0032] Among them, see Figure 3 and Figure 4 The blowing assembly 10 shown in the figure includes a straight tube 11, a bidirectional threaded rod 12 is rotatably installed in the straight tube 11, and the two ends of the bidirectional threaded rod 12 are respectively inserted into two mounting seats 9, a limit strip 13 is fixed in the straight tube 11, and a piston plate 14 plugged into the limit strip 13 is threadedly sleeved on the outer side of the bidirectional threaded rod 12, and docking pieces 15 plugged into the mounting seats 9 are installed at both ends of the straight tube 11, and a blowing pipe 16 is fixed at both ends of the straight tube 11, and a plurality of air outlet pipes 17 are equidistantly installed on the outer side of the blowing pipe 16, a transmission gear 18 is fixed to the outer end of the bidirectional threaded rod 12, and a driving assembly 19 for rotating the transmission gear 18 is installed on the inner side of the two toothed belts 7;

[0033] It should be noted that: the driving assembly 19 drives the transmission gear 18 to rotate, so that the bidirectional threaded rod 12 can rotate, thereby realizing the movement of the piston plate 14 in the straight tube 11, so that the blowing tubes 16 at both ends of the straight tube 11 can correspondingly inhale and blow air, so that the air flow outside the ink is disturbed to improve its quick-drying efficiency.

[0034] Among them, see Figure 7 The mounting seat 9 shown in the figure includes a mounting platform 20 fixed to the outer side of the toothed belt 7, the inner side wall of the mounting platform 20 is slidably connected to the outer end of the bidirectional threaded rod 12, and both ends of the mounting platform 20 are installed with limit members 21;

[0035] It should be noted that: a plurality of mounting seats 9 are designed, and blowing components 10 with different spacings can be installed correspondingly between different spacing patterns, so that the blowing efficiency is higher;

[0036] Also, see Figure 7 The limiting member 21 shown in the figure includes an L-shaped plate 22 fixed on the outer side of the toothed belt 7, a C-shaped seat 23 is fixed on the outer side of the toothed belt 7 at a position corresponding to the L-shaped plate 22, and a connecting rod 24 is slidably inserted in the L-shaped plate 22, a C-shaped plate 25 is fixed to the bottom of the connecting rod 24, and a pull cap is fixed to the top of the connecting rod 24, and a tension spring 26 fixed to the pull cap and the outer wall of the L-shaped plate 22 is sleeved on the outer side of the connecting rod 24;

[0037] It should be noted that: through the designed C-shaped seat 23 and the C-shaped plate 25, the bidirectional threaded rod 12 can be pressed together to make its installation stable. At the same time, personnel only need to pinch the pull cap to pull out the connecting rod 24, so that the C-shaped plate 25 is separated from the bidirectional threaded rod 12, making it convenient for personnel to disassemble the bidirectional threaded rod 12.

[0038] It is worth noting that both ends of the bidirectional threaded rod 12 are smooth planes, and only the portion inside the straight tube 11 is provided with a bidirectional thread groove.

[0039] Also, see Figure 7 The docking member 15 shown in the figure includes an L-shaped seat 27 fixed to the outer end of the straight tube 11, two docking rods 28 are slidably inserted in the L-shaped seat 27, and a docking block 29 is fixed to the outer side of the C-shaped plate 25 close to the straight tube 11, the docking rod 28 abuts against the docking block 29, and a docking column 30 fixed to the outer wall of the straight tube 11 is slidably inserted at one end of the docking rod 28, and an extrusion spring 31 for pushing the docking rod 28 outward is sleeved on the outer side of the docking column 30;

[0040] It should be noted that: the designed docking rod 28 and the docking block 29 are abutted against each other, so that when the bidirectional threaded rod 12 rotates, the straight tube 11 can be in a non-rotating state;

[0041] It is worth noting that: a connecting plate 32 is fixed to the outer ends of the two docking rods 28. When disassembling the straight pipe 11, the personnel only need to pinch the connecting plate 32 and move it backward to separate the docking rod 28 from the docking block 29, which is convenient for disassembly.

[0042] The principle of quick drying of paper after ink printing: First, the personnel insert the paper between the printing roller 2 and the squeezing roller 3 according to the operation, and print the ink on the printing paper through the rotation of the printing roller 2 and the squeezing roller 3. As the paper moves, the paper after ink printing passes above the toothed belt 7, and the driving component 19 drives the multiple blowing components 10 to operate. Then, through the rotation of the toothed belt 7, the multiple blowing components 10 can blow and inhale the ink pattern at the bottom of the printing paper, thereby improving the flow of gas and thus improving its quick drying efficiency;

[0043] The rotation of the bidirectional threaded rod 12 causes the piston plate 14 to move back and forth, so that the two ends of the straight tube 11 suck and blow air in turn, thereby achieving blowing and suction processing on the ink pattern, thereby improving the efficiency of ink drying.

[0044] In this scheme, a processing technology for gravure printing paper of ink comprises the following steps:

[0045] S1. The paper passes through the printing roller 2 and the squeezing roller 3, bypasses the steering roller 4, and finally docks with the winding drum, and the ink is printed on the printing paper through the rotation of the printing roller 2 and the squeezing roller 3;

[0046] S2. The blowing assembly 10 is designed to blow the printed paper just printed with ink to make the ink dry quickly;

[0047] S3. Roll up the dried printing paper.

[0048] It should be noted that: in the present solution, the movement of the piston plate 14 in the straight tube 11 enables the blowing tubes 16 at both ends of the straight tube 11 to correspondingly inhale and blow air, wherein the blowing speed is related to the moving speed of the piston plate 14, that is, the faster the toothed belt 7 rotates, the faster the speed of the extruded gas, and at the same time, the circulation of the air flow is accelerated, which mainly dries the ink pattern and improves the drying efficiency. Among them, the straight tube 11 can be installed with existing equipment such as a heating plate, so that the blowing temperature is between 100°C and 150°C, and the blowing wind speed is controlled at 10-20m / S.

[0049] Example 2

[0050] See also Figure 5 and Figure 6 , this embodiment further explains the embodiment 1, the driving assembly 19 shown in the figure includes two driving shafts 36, the outer ends of the two driving shafts 36 are rotatably connected through the support frame, and the two ends of the two driving shafts 36 are fixed with steering gears 37 meshing with the driving gear 6, the outer ends of the two steering gears 37 on one side are meshed with external toothed belts 38, and the external toothed belts 38 are meshed with the plurality of transmission gears 18;

[0051] It should be noted that: when the steering gear 37 rotates with the driving gear 6, it reverses synchronously, thereby driving the external toothed belt 38 to rotate, and the external toothed belt 38 meshes with the transmission gear 18, thereby driving the transmission gear 18 to rotate, and controlling the reciprocating movement of the piston plate 14 on the bidirectional threaded rod 12.

[0052] Example 3

[0053] See also Figure 4 This embodiment further explains other embodiments. The linkage member 8 shown in the figure includes a linkage gear 1 33 fixed to the outer end of the steering roller 4, a linkage gear 2 34 is fixed to the outer end of one of the driving rods 5, and a linkage belt 35 is meshed between the linkage gear 1 33 and the linkage gear 2 34.

[0054] It should be noted that one end of the steering roller 4 is connected to the driving device to achieve rotation, and then through the action of the linkage gear 1 33 and the linkage belt 35, the linkage gear 2 34 and the driving rod 5 are rotated synchronously. Under the action of the toothed belt 7, the two driving rods 5 are driven to rotate synchronously, thereby providing power to the steering gear 37 in the driving assembly 19.
