Abstract
Description
Technical Field
[0001] This utility model belongs to the field of printing press technology, specifically relating to an ink temperature control device for digital printing presses. Background Technology
[0002] Digital printing presses, as key equipment in the modern printing industry, are widely used due to their high efficiency and flexibility. Their working principle involves precisely spraying ink from the printhead onto the substrate to reproduce images and text. The fluidity and stability of the ink play a decisive role in print quality. In cold regions, the ambient temperature is often significantly lower than the optimal operating temperature range of digital printing presses. When the ink temperature is too low, its viscosity increases dramatically, leading to poor ink fluidity. This causes uneven ink droplet size and shape, severely affecting print clarity and color reproduction, resulting in blurry images, color deviations, and other problems. This reduces print quality and can even lead to printing failures, wasting materials and time. Furthermore, excessively low ink temperature can cause ink to solidify or clog in the pipes and printheads, increasing equipment maintenance costs and downtime, and impacting production efficiency.
[0003] Therefore, developing an ink temperature control device that can effectively control the temperature of ink in cold regions and prevent the ink temperature from being too low and affecting the use of printing presses is of great practical significance and market demand. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figures 1-3 This utility model provides the following technical solution: an ink temperature control device for a digital printing machine, comprising multiple ink cartridges 1, a heating device 2, a print head 3, multiple ink sacs 4, and a fixing device 5 for fixing the multiple ink sacs 4. The heating device 2 is installed on the surface of each ink cartridge 1. A first ink tube 6 is installed at the bottom of each ink cartridge 1, and a second ink tube 7 is installed at the top of each ink sac 4. The first ink tube 6 and the second ink tube 7 correspond to each other in pairs. A filter 8 is installed between the corresponding first ink tube 6 and the second ink tube 7. The fixing device 5 is installed at the top of the print head 3. The ink sacs 4 are installed inside the fixing device 5. A first temperature sensor is installed inside the ink cartridge 1, and a second temperature sensor is installed inside the ink sac 4. The ink cartridge 1 is located at the top of the print head 3.
[0018] In this embodiment, the fixing device 5 includes a square fixing frame 51 installed on the top of the print head 3. The square fixing frame 51 has several partitions 52 installed inside. The partitions 52 divide the square fixing frame 51 into multiple mounting cavities 53 for limiting and fixing the ink sac 4. Heating plates 54 are installed on both sides of the partitions 52. Heating plates 54 are also installed on the inner walls of the square fixing frame 51 corresponding to the partitions 52.
[0019] Specifically, the mounting cavity 53, separated by the partition 52, facilitates the positioning and fixing of the ink sac 4, thereby improving the stability of the ink sac 4 during use. After the ink sac 4 is installed in the mounting cavity 53, heating plates 54 are provided on both sides of the partition 52 and on both sides of the corresponding square fixing frame 51. The heating plates 54 can keep the ink in the ink sac 4 warm, effectively improving the ink fluidity and preventing the ink temperature from dropping and causing poor fluidity, which would affect the printing effect.
[0020] In this embodiment, the heating device 2 is a flexible heating film, which is strip-shaped and covers the outer surface of the ink cartridge 1.
[0021] Specifically, the flexible heating film has high heating efficiency and is lightweight. After being wrapped and installed on the outer surface of the ink cartridge 1, it can efficiently and quickly heat the ink inside the ink cartridge 1, thereby effectively avoiding the impact of low ink temperature on printing effect.
[0022] In this embodiment, the filter 8 includes a filter body 81, with a first connecting pipe 82 and a second connecting pipe 83 respectively provided at both ends of the filter body 81. The first ink tube 6 is inserted into the first connecting pipe 82, and the second ink tube 7 is inserted into the second connecting pipe 83.
[0023] Specifically, the ink in the ink cartridge 1 may contain some impurities. The filter 8 can filter the ink, and the filtered ink can effectively improve the printing effect when it enters the ink sac 4 for use by the print head 3.
[0024] In this embodiment, the first temperature sensor is electrically connected to the heating device 2 via an external first temperature controller, and the second temperature sensor is electrically connected to the heating element 54 via an external second temperature controller.
[0025] Specifically, by setting a first temperature controller and a second temperature controller in conjunction with corresponding first temperature sensors and second temperature sensors, the heating temperature of the ink in ink cartridge 1 and ink sac 4 can be controlled, which can prevent the printing pattern effect from being affected by the ink heating temperature being too high.
[0026] It should be noted that neither the first temperature sensor nor the second temperature sensor is shown in the figure. The heating temperature control of the heating device 2 and the heating element 54 by the first and second temperature controllers in conjunction with the first and second temperature sensors is a conventional technology in this field. The specific circuit control relationship will not be described in detail in this application. The specific ink heating temperature in the ink cartridge 1 and the ink insulation temperature in the ink sac 4 need to be adjusted by the operator according to the actual situation.
[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
