[0030] Reference Figure 1-3The utility model provides an embodiment: a dampening liquid cooling device for an offset printing press, comprising a shell 1 and a shell 3 8, wherein the upper and lower sides of the shell 3 8 are fixedly connected with heat dissipation fins 14, the top of the shell 3 8 is fixedly connected with a water storage tank 11, the bottom of the water storage tank 11 is fixedly connected with a plurality of water spray heads 22, the top of the water storage tank 11 is fixedly connected with a water pump 13, the input end of the water pump 13 is fixedly connected with a pipe 29, the bottom end of the pipe 29 is connected with the inside of the shell 3 8, the output end of the water pump 13 is fixedly connected with a pipe 4 12, a circulating water pipe 21 is arranged inside the shell 3 8, and one end of the circulating water pipe 21 is fixedly connected with Pipe three 10, the other end of the circulating water pipe 21 is fixedly connected to pipe five 15, the front part of the shell 1 is fixedly connected to pipe 3, the rear part of the shell 1 is fixedly connected to water pump two 16, the output end of water pump two 16 and the front end of pipe five 15 are connected, the inside of the shell 1 is slidably connected to the filter screen 20, the top of the filter screen 20 is fixedly connected to the sealing seat 6, the left and right sides of the shell 1 are provided with fixed components, the pipe four 12 is connected to the water tank 11, the pipe two 9 and the shell three 8 are internally connected, the bottom of the sprinkler head 22 is located above the circulating water pipe 21, and the inside of the sprinkler head 22 and the inside of the water tank 11 are connected.

[0031] Specifically, when it is necessary to replace the filter 20 that has been used for a long time, the handle 15 is pulled outward to drive the latch rod 17, and the latch rod 17 moves outward to drive the baffle 19 to squeeze the spring 18. At this time, the latch rod 17 is disengaged from the groove inside the sealing seat 6 (not shown in the figure). At this time, the handle 27 is pulled outward to drive the sealing seat 6 upward to replace the filter 20. After replacement, the handle 15 is released to allow the spring 18 to reset and drive the baffle 19 and the latch rod 17 to move inward and insert into the groove in the sealing seat 6. At this point, after the filter 20 has been used for a long time, the filter 20 can be replaced alone without replacing the entire device to reduce costs.

[0032] Reference Figure 2 and 4 The fixing component includes a shell 24, the bottom of the shell 24 is fixedly connected to the outside of the shell 1, the inside of the shell 24 is slidably connected with a latch rod 17, the outside of the latch rod 17 is sleeved with a spring 18, the side of the latch rod 17 close to the shell 1 is fixedly connected with a baffle 19, the bottom of the shell 1 is fixedly connected with a plurality of support columns 2, the top of the sealing seat 6 is fixedly connected with a handle 27, the outside of the sealing seat 6 is slidably connected to the top of the shell 1, one end of the spring 18 is fixedly connected to the inner wall of the shell 24, the other end of the spring 18 is fixedly connected to the end of the baffle 19 away from the shell 1, the outside of the baffle 19 is slidably connected to the inside of the shell 24, and the end of the latch rod 17 away from the shell 1 is fixedly connected with a handle 5.

[0033] Specifically, the fountain solution enters the shell 1 through the pipe 13, and the valve on the pipe 13 can control the inflow and outflow of the fountain solution. After filtering, the fountain solution is passed from the pipe 5 15 to the shell 3 8 and then into the circulating water pipe 21 by the water pump 2. The cold water in the water tank 11 is sprayed to the shell 3 8 by the sprinkler head 22. The cold water passes through the circulating water pipe 21 to cool the fountain solution in the circulating water pipe 21. The cooled fountain solution can be returned to the offset printing machine through the pipe 3 10 for reuse. The valve on the pipe 3 10 can control the inflow and outflow of the fountain solution. The heat absorbed by the cold water is dissipated by the cooling fins 14 at both ends and becomes cold again. At this time, the water pump 13 is started, and the water is sucked into the water pump 13 again through the pipe 2 9, and then the cold water is discharged from the output end into the pipe 4 12 and returned to the water tank 11. This solves the problem that the cooling effect is poor when cooling the fountain solution, and the long-term circulation still causes the temperature of the fountain solution to be too high.

[0034] Working principle: Pulling handle 15 outward drives latch rod 17, latch rod 17 moves outward and drives baffle 19 to squeeze spring 18, at this time latch rod 17 is out of the groove inside sealing seat 6 (not shown in the figure), at this time pull handle 27 outward and drive sealing seat 6 upward, at this time replace filter screen 20, after replacement, release handle 15, spring 18 resets and drives baffle 19 and latch rod 17 to move inward and insert into the groove in sealing seat 6, so that the replacement of filter screen 20 is completed. Cold water in water storage tank 11 is sprayed into the inside of housing 3 8 by water spray head 22, cold water passes through circulating water pipe 21, cools the fountain solution in circulating water pipe 21, and the heat absorbed by cold water is dissipated by heat dissipation fins 14 at both ends and becomes cold again, at this time start water pump 13, water is sucked into water pump 13 again through pipe 29, and then the cold water is discharged into pipe 4 12 from the output end and returns to water storage tank 11 to complete the cycle.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
