Description

Technical Field

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

[0002] Printing is the process of transferring ink from photos, anti-counterfeiting manuscripts, etc. to the surface of paper, fabrics, plastics, leather and other materials through plate making, inking, pressurization and other processes. The widespread use of printing technology has greatly facilitated people's lives. During the printing process, the printing roller will generate a lot of heat after working for a long time. Continuous high-temperature printing of the printing roller will affect the printing effect.

[0003] The existing patent CN220923529U discloses a cooling device for a printing machine, including a top frame, a vertical plate and a printing roller, two groups of the vertical plates are distributed and installed on both sides of the top frame, and the printing roller is rotatably installed on the opposite inner sides of the two groups of vertical plates. The top frame and the vertical plates are provided with a moving mechanism, and the moving mechanism is provided with a steering mechanism. The utility model drives the steering mechanism and the cooling fan to circulate and reciprocate linear motion through the motor in the moving mechanism to blow air evenly to the printing roller and increase the heat exchange efficiency of the heat on the surface of the printing roller. When the cooling fan is working, the user can use the first motor in the steering mechanism to drive the top of the main machine to rotate along the curve, cooperate with the connection and rotation of the connecting frame and the connecting shaft, and ensure that the bottom of the cooling fan can be turned to different angles, thereby adjusting the angle of the cooling fan so that the cooling fan can keep blowing directly on the printing roller, ensuring a good blowing and heat dissipation effect of the printing roller.

[0004] Based on the search of the above patents and in combination with the cooling devices in the prior art, it is found that when the above cold zone device is in private use, the motor drives the spiral screw to rotate, the cooling fan is moved back and forth, and the first motor cooperates with the top of the main machine to rotate in a curve to adjust the angle of the cooling fan. However, in actual use, the fan only dissipates heat from the surface of the printing roller, and the continuous operation of the printing roller will cause the entire printing roller to generate a large amount of heat. The wind blown by the cooling fan cannot meet the overall heat dissipation of the printing roller, resulting in poor heat dissipation effect. In addition, the operation of the cooling fan and components such as the first motor will generate heat, which will be blown to the printing roller by the fan blades, affecting the heat dissipation effect, thereby reducing practicality.
