Description

Technical Field

[0001] The utility model relates to the technical field of printing machines, in particular to a cooling water circulation device for a printing machine. Background Art

[0002] A printing press is generally composed of mechanisms such as plate loading, inking, embossing, and paper feeding. When the printing press is running at full capacity, the temperature may be too high from time to time, and the overload protection will occur, causing the printing press to shut down. During the printing process, excessive temperature will cause ink instability, so a cooling water circulation device is required for cooling.

[0003] However, the existing printing press cooling water circulation device may have problems in actual use, such as the one published on October 13, 2020, with publication number

[0004] Chinese utility model patent CN211662798U discloses a cooling water circulation device for an aluminum foil printing machine.

[0005] The implementation principle of this embodiment is: when the water flows through the printing machine and is discharged to the cooling tank 6 through the water outlet pipe 4, the V-shaped rod 9 is driven to rotate by the motor 1, and the V-shaped rod 9 and the bottom end of the motor 2 are fixed to drive the motor 2 10 to rotate and connect between the circular frame 12 between the two L-shaped rods, so that the fan blades 11 cool the water flowing into the cooling tank 6 through the water outlet pipe 4 of the printing machine under the action of the motor 2 10, and the cooled water is re-input into the printing machine through the water inlet pipe 2 to realize the recycling of cooling water and save water resources. The water flows through the water drop hole 16 into the cooling tank 6 through the water drop hole 16, and is cooled by the water flow at the height of the drop hole and the bottom end of the cooling tank 6. When the water flows into the cooling tank 6 through the water drop hole 16, a force is applied to the stirring paddle 17, so that the stirring paddle 17 rotates and drives the water flow in the cooling tank 6 to rotate and cool.

[0006] This solution only installs a fan structure and a stirring structure in a sealed tank. The simple stirring structure does not have the effect of heat dissipation and cooling. The fan is arranged in the sealed tank body, and the temperature of the air flow blown out by the fan is affected by the temperature inside the tank body, and it is difficult to cool down the cooling water after absorbing heat, resulting in a general cooling effect on the cooling water after absorbing heat. Therefore, a printing press cooling water circulation device is proposed based on the above. Utility Model Content
