It should be noted that the examples and features in the examples of the present application can be combined with each other without conflict.

[0018] In the following description, many specific details are set forth in order to provide a thorough understanding of the utility model, however, the utility model can also be implemented in other ways different from the description herein, therefore, the utility model is not limited to the specific examples disclosed in the following description.

[0019] Example 1: As Figures 1-4 As shown, this utility model provides a technical solution: a constant temperature base plate for installing piezoelectric printheads of digital printing machines, including a constant temperature base plate assembly 1. The constant temperature base plate assembly 1 includes a base plate 101 and a mounting plate 102. The base plate 101 is disposed on the top of the mounting plate 102. The top of the mounting plate 102 is provided with a mounting slot 103. A constant temperature copper tube 104 is installed inside the mounting slot 103. One end of the constant temperature copper tube 104 is connected to a constant temperature fluid inlet 105, and the other end of the constant temperature copper tube 104 is connected to a constant temperature fluid outlet 106. The width of the mounting slot 103 is 8mm, and the shape of the mounting slot 103 is S-shaped. Copper pagoda nozzles are provided on the constant temperature fluid inlet 105 and the constant temperature fluid outlet 106. The base plate 101 and the mounting plate 102 are provided with multiple mounting holes.

[0020] In this embodiment, an 8mm wide mounting slot 103 is milled into the top of the mounting plate 102. A thermostatic copper tube 104 is laid inside the mounting slot 103. To ensure uniform heat dissipation, the mounting slot 103 is designed in an S-shape. After the thermostatic copper tube 104 is laid, the gaps are filled with thermally conductive silicone. After the thermally conductive silicone is completely dry, the surface is polished smooth. The thermostatic fluid inlet 105 and thermostatic fluid outlet 106 facilitate the delivery of thermostatic fluid to the thermostatic copper tube 104, providing a suitable temperature for the piezoelectric printhead. This ensures that the temperature fluctuation of the printhead is minimal during long-term printing, allowing parameters such as ink ejection speed and droplet size to remain stable. This, in turn, ensures uniform color and clear lines in the printed pattern, greatly improving the consistency of printing quality, increasing printing efficiency and quality. At the same time, it reduces physical changes such as thermal expansion and contraction of the printhead due to temperature factors, reduces the wear and tear of internal parts of the printhead, and reduces the risk of malfunctions such as blockage caused by abnormal temperature, thereby extending the service life of the piezoelectric printhead.

[0021] The working principle of this embodiment is as follows: In use, the top of the mounting plate 102 is first milled with an 8mm wide mounting slot 103. A thermostatic copper tube 104 is laid inside the mounting slot 103. To ensure uniform heat dissipation, the mounting slot 103 is designed in an S-shape. After the thermostatic copper tube 104 is laid, the gaps are filled with thermally conductive silicone. After the thermally conductive silicone is completely dry, the surface is polished smooth. The thermostatic fluid inlet 105 and thermostatic fluid outlet 106 facilitate the delivery of thermostatic fluid to the inside of the thermostatic copper tube 104, providing a suitable temperature for the piezoelectric printhead. This allows parameters such as the ink ejection speed and droplet size of the printhead to remain stable, thereby ensuring uniform color and clear lines in the printed pattern, greatly improving the consistency of printing quality and increasing printing efficiency.
