Description

Technical Field

[0001] The utility model relates to the technical field of dampening solution for printing presses, and particularly relates to a device for recycling dampening solution for printing presses. Background Art

[0002] The dampening solution is also called wetting solution, water tank solution, and fountain solution. The dampening solution contains wetting agents to change the surface tension of the printing plate surface. In offset printing, the printing plate forms images and blank parts with ink and dampening solution, and the principle of oil-water incompatibility is used to achieve graphic reproduction. As the saying goes, mastering water is equivalent to mastering offset printing. This fully demonstrates the importance of water in offset printing. The pH value of the dampening solution is a necessary condition for the formation of hydrophilic inorganic salts on the blank part of the printing plate and to keep it clean, and it has a great influence on the ink transfer effect. If the pH value of the dampening solution is too acidic or too alkaline, it is not conducive to the normal operation of offset printing. The existing dampening solution for printing presses is not convenient for recycling, the efficiency of filtering the dampening solution is low, and the recycling efficiency is low.

[0003] The existing patent (Publication No.: CN210121377U) discloses a filtering and circulating device for dampening solution of a printing press, which greatly improves the efficiency of filtering the dampening solution and the recycling efficiency of the dampening solution. In the process of implementing this solution, it is found that the following problems in the prior art have not been well solved:

[0030] A toggle block 11 is connected to the top of the guide block 10, and the toggle block 11 is used to clean the dampening solution above the guide block 10 to prevent it from accumulating. An elastic belt 15 is connected to the outside of the toggle block 11, and sliding rods 12 are connected to both sides of the toggle block 11. The sliding rods 12 drive the toggle block 11 to move to ensure its use. A connecting rope 14 is connected to the bottom of the sliding rod 12, and a sliding groove 13 is connected to the outside of the sliding rod 12.

[0031] See the attached drawings in the specification Figures 1-4 A trapezoidal protrusion is provided at the center of the first filter screen 4. The first filter screen 4 is connected to the device body 1 by sliding connection. The first filter screen 4 and the pull ring 5 are installed in an integrated manner. The fountain solution is preliminarily filtered through the first filter screen 4, and the fountain solution is spread out to improve the filtering effect.

[0032] See the attached drawings in the specification Figures 1-4 The connection between the fixed block 6 and the device body 1 is a hot-melt connection. The fixed block 6 and the insertion rod 7 are installed in an integrated manner. The connection between the insertion rod 7 and the first filter screen 4 is a sliding connection. The fixed block 6 cooperates with the insertion rod 7 to quickly disassemble and fix the first filter screen 4, which is convenient for subsequent maintenance.

[0033] See the attached drawings in the specification Figures 1-4 , connecting rods 8 are evenly and equidistantly distributed above the second filter screen 9, and the second filter screen 9 forms an integrated installation structure with the first filter screen 4 through the connecting rods 8. The aperture of the second filter screen 9 is smaller than the aperture of the first filter screen 4. The second filter screen 9 performs secondary filtration, and through the connecting rods 8, it can be disassembled as an integrated whole with the first filter screen 4 to ensure use.

[0034] See the attached drawings in the specification Figures 1-4The guide blocks 10 are symmetrically distributed on both sides of the device body 1.

[0036] Working principle: When in use, first, place the fountain solution from the top cover 2 into the interior of the device body 1, and contact it with the first filter 4. As the fountain solution enters, it moves along the first filter 4 toward the surroundings, and quickly moves to both sides of the first filter 4 along the slope to achieve the purpose of spreading. After being filtered by the first filter 4, it falls on the top of the second filter 9. After double filtration, it accumulates at the bottom. After long-term use, open the top cover 2, grab the pull ring 5 and lift it, so that it drives the first filter 4 to rise, and at the same time pulls the second filter 9 up through the connecting rod 8, and finally clean it.

[0037] As mentioned above, when it is needed, the dampening liquid is discharged through the liquid outlet 16, and at the same time, the pull block is pulled so that it drives the connecting rope 14 to move outward. The connecting rope 14 pulls the sliding rod 12, so that the toggle block 11 moves above the guide block 10 to discharge all the accumulated dampening liquid. When it is pulled to the limit, the pull block is released, and the elastic band 15 drives the toggle block 11 to reset, and the above steps are repeated.
