Description

Technical Field

[0001] This utility model relates to the field of printing technology and belongs to a printing ink curing mechanism. Background Technology

[0002] In traditional printing equipment, ink is typically supplied stably through ink tanks. However, during the printing process, the ink in the ink tank may be left stagnant for extended periods or subjected to improper storage conditions, both of which can lead to ink curing. Once the ink cures, it can clog printheads, pipes, and other components, causing printing interruptions, and can also result in quality problems such as blurry or missing colors in the printed image, severely impacting production efficiency and product quality. For example, in decorative paper printing, where printing jobs may last for a long time, ink curing occurs frequently, resulting in significant material waste and increased equipment maintenance costs. Furthermore, the heat generated by the printing equipment during operation can raise the temperature of the ink, further exacerbating the curing process. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution:

The top of the ink supply box has an ink inlet, and the bottom of the ink supply box has a discharge channel. The discharge outlet of the discharge channel extends to the outside of the ink supply box. A partition is horizontally disposed inside the ink supply box, dividing the ink supply box into an ink chamber and a heat insulation chamber. An anti-curing mechanism is disposed inside the ink chamber, and a vacuum heat insulation layer is disposed inside the heat insulation chamber.

[0006] Preferably, the ink inlet is provided with a sealing cap connected to the top, and the ink inlet is funnel-shaped.

[0007] Preferably, the anti-curing mechanism includes a mounting plate connected to both sides of the ink cavity. A transmission screw is connected to the middle of the mounting plate via a bearing seat. An agitator is movably connected to the transmission screw. Guide columns are movably connected to both sides of the agitator. The two ends of the guide columns are connected to the mounting plate.

[0010] Compared with the prior art, this utility model provides a printing ink-resistant curing mechanism, which has the following advantages:

[0011] This utility model's ink supply box is equipped with an ink chamber and a heat insulation chamber. The ink chamber contains an anti-curing mechanism that continuously agitates the ink, ensuring its fluidity and preventing partial curing due to prolonged stillness. The heat insulation chamber contains a vacuum insulation layer that blocks heat generated during operation, preventing heat from entering the ink chamber through the bottom of the ink supply box. This ensures stable ink temperature and prevents curing due to overheating. The combination of these two features effectively prevents ink curing, reduces ink waste, and improves production efficiency and product quality.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily obscuring the concepts of this utility model.

[0019] See Figures 1-4 This application provides a printing ink anti-curing mechanism, including a main body 1. The main body 1 has an assembly groove 11, and an ink supply box 2 is disposed in the assembly groove 11. The top of the ink supply box 2 has an ink inlet 21, and the bottom of the ink supply box 2 has a discharge channel 22. The discharge port of the discharge channel 22 extends to the outside of the ink supply box 2. A partition 3 is horizontally disposed inside the ink supply box 2, and the partition 3 divides the ink supply box 2 into an ink chamber 4 and a heat insulation chamber 5. An anti-curing mechanism 6 is disposed in the ink chamber 4, and a vacuum heat insulation layer 7 is disposed in the heat insulation chamber 5. The vacuum heat insulation layer 7, based on the high heat insulation performance of the vacuum space interlayer, reduces the diffusion of heat in the vacuum space, blocks the heat generated by the main body 1 during operation, prevents heat from entering the ink chamber 4 through the bottom of the ink supply box 2, ensures the stability of the ink temperature, and avoids the ink curing due to the increase in temperature.

[0020] The anti-curing mechanism 6 includes mounting plates 61 connected to both sides of the ink chamber 4. A transmission screw 62 is connected to the middle of the mounting plate 61 via a bearing seat. An agitator 63 is movably connected to the transmission screw 62. Guide posts 64 are movably connected to both sides of the agitator 63. Both ends of the guide posts 64 are connected to the mounting plate 61. A servo motor 65 is connected to one end of the transmission screw 62 via a coupling. A transmission nut 66 is threadedly connected to the transmission screw 62. A connecting block 67 is provided on the top of the mounting plate 61. The transmission nut 66 and the connecting block 67 are fixedly connected. The mounting plate 61 has several fluid gaps 611. The lower part of the mounting plate 61 is grid-like. The servo motor 65 can drive the transmission screw 62 to perform intermittent forward and reverse rotation. During the rotation of the transmission screw 62, the transmission nut 66 is driven by the thread to perform reciprocating linear motion along the axis of the transmission screw 62. The mounting plate 61, which is connected to the transmission nut 66, performs reciprocating linear motion synchronously, and the ink is reciprocated and agitated by the mounting plate 61. During the agitation, the fluid gaps 611 allow the ink to pass through, increasing the shear surface of the mounting plate 61 on the ink, improving the shearing effect on the ink, preventing the ink from standing still, ensuring the fluidity of the ink, and avoiding partial solidification of the ink due to prolonged standing.

[0021] The working principle of this utility model:

[0022] When the ink chamber 4 of the ink supply box 2 is filled with ink, in order to prevent the ink from solidifying due to prolonged standing, the servo motor 65 is started. The servo motor 65 drives the transmission screw 62 to perform intermittent forward and reverse rotation. During the rotation, the transmission screw 62 drives the transmission nut 66 to perform reciprocating linear motion along the axis of the transmission screw 62 through thread transmission. The mounting plate 61 connected to the transmission nut 66 performs reciprocating linear motion synchronously. The ink is reciprocated and agitated by the mounting plate 61 to ensure the fluidity of the ink and prevent the ink from partially solidifying due to prolonged standing.

[0023] During the operation of the main body 1, the heat generated by the main body 1 is blocked by the vacuum insulation layer 7, preventing heat from entering the ink chamber 4 through the bottom of the ink supply box 2, ensuring the stability of the ink temperature, and preventing the ink from curing due to the increase in temperature.

[0024] The above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
