Description

Technical Field

[0001] This utility model belongs to the field of ink temperature regulation, and in particular relates to an ink constant temperature device. Background Technology

[0002] In digital printing equipment, the ambient temperature of the ink environment affects its properties, thus impacting print quality. For example, excessively high temperatures decrease ink viscosity, leading to excessive ink flow. This causes ink to overflow excessively from the printhead, resulting in ink dripping or splattering, blurry edges, uneven line thickness, and reduced printing accuracy. Conversely, excessively low temperatures increase ink viscosity, decreasing flowability and increasing resistance within the printhead. This results in insufficient jet pressure, causing ink breaks or insufficient ink volume, leading to defects such as blank areas and broken lines. Therefore, maintaining a constant ink temperature is crucial for optimal print quality. The existing method of ink temperature adjustment involves cooling or heating the ink near the printhead. Because the adjustment point is close to the printhead, the ink needs to be heated or cooled quickly during adjustment. This can result in the external ink reaching the appropriate temperature while the internal ink remains outside the required temperature, or the internal ink reaching the required temperature while the external ink is too hot or too cold. This leads to uneven ink temperature adjustment and the aforementioned problems persist. Utility Model Content

[0003] The ink temperature control device provided by this utility model aims to solve the problem in the prior art where uneven ink temperature adjustment leads to excessively high or low ink viscosity, thus affecting the printing effect.

[0004] This utility model is implemented as follows: an ink temperature control device, comprising:

[0005] The tank body has an internal chamber. The tank body has an inlet and an outlet that communicate with the chamber. The inlet is used to communicate with the outlet of the cold water tank, and the outlet is used to communicate with the inlet of the cold water tank. The cold water tank is used to circulate a constant-temperature liquid into the chamber.

[0006] The ink tube includes a first end and a second end, with the middle part of the ink tube placed in the chamber. Both the first end and the second end of the ink tube extend out of the tank body. The first end is used to connect to the ink tank, and the second end is used to communicate with the ink inlet of the printing device.

[0007] Furthermore, the water inlet is located at the bottom of the tank, and the water outlet is located at the top of the tank.

[0008] Furthermore, the portion of the ink tube placed within the cavity has a multi-segment curved structure.

[0009] Furthermore, the multi-segment curved structure is a spiral columnar structure, and the number of ink tubes is several. Several spiral columnar ink tubes are vertically arranged in the cavity, and the first end of each ink tube is connected to an ink tank of a certain color ink.

[0010] Furthermore, the outer wall of the tank is provided with heat-insulating material.

[0011] Furthermore, the first and second ends of the ink tube are both located on the same side of the can body.

[0012] Furthermore, a fixing part is provided on the outside of the tank.

[0013] Furthermore, the tank body includes a bottom plate, side plates disposed on the bottom plate, and a top plate connected to the side plates and disposed opposite to the bottom plate, the bottom plate, the side plates, and the top plate forming the chamber.

[0014] The beneficial effects achieved by this utility model are as follows: by setting a chamber inside the tank and connecting it to a cold water tank through an inlet and an outlet, a constant-temperature liquid can be circulated and injected into the chamber. When the ink tank delivers ink to the printing equipment, the ink can first pass through the ink tube placed in the chamber before flowing into the printing equipment. The constant-temperature liquid in the chamber can completely surround the ink tube, thereby quickly regulating the temperature of the ink. This ensures that the ink reaches the required constant temperature when entering the printing equipment for printing operations, thus guaranteeing the printing effect. Attached Figure Description

[0020] 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. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] See Figures 1-2 This utility model provides an ink temperature control device, including a tank 1 and an ink tube 2. The tank 1 has a chamber 11 inside, and an inlet 12 and an outlet 13 communicating with the chamber 11. The inlet 12 is connected to the outlet of a cold water tank (not shown), and the outlet 13 is connected to the inlet of the cold water tank. The cold water tank circulates a temperature-controlled liquid into the chamber 11, filling it with the liquid. The temperature-controlled liquid can be a cold source or a heat source. The ink tube 2 includes a first end 21 and a second end 22, with the middle portion of the ink tube 2 positioned within the chamber. Inside chamber 11, the first end 21 and the second end 22 of ink tube 2 both extend out of the tank 1. The first end 21 is used to connect to the ink tank (not shown in the figure), and the second end 22 is used to connect to the ink inlet of the printing device (not shown in the figure). This allows the ink in the ink tank to first enter the ink tube 2 through the first end 21 when it is delivered to the printing device. The constant temperature liquid in chamber 11 can regulate the temperature of the ink in the ink tube 2 to reach the required constant temperature. Then the ink enters the printing device from the second end 22.

[0022] By setting a chamber 11 inside the tank 1 and connecting it to a cold water tank through an inlet 12 and an outlet 13, a constant-temperature liquid can be circulated into the chamber 11. When the ink tank delivers ink to the printing equipment, the ink can first pass through the ink tube 2 placed in the chamber 11 before flowing into the printing equipment. The constant-temperature liquid in the chamber 11 can completely surround the ink tube 2, thereby quickly regulating the temperature of the ink. This ensures that the ink reaches the required constant temperature when entering the printing equipment for printing, thus guaranteeing the printing effect.

[0023] The ink temperature control device provided in this embodiment can effectively and quickly adjust the ink to the required constant temperature, thereby improving the printing effect.

[0024] Specifically, the temperature of the constant-temperature liquid input into chamber 11 in the cold water tank can be adjusted according to the actual environmental requirements. During actual printing operations, ink temperatures that are too high or too low will affect the ink's characteristics, thereby affecting the printing effect. Therefore, the ink temperature must always be maintained between 25℃ and 26℃ when it is ejected from the printhead. Therefore, when used in a high-temperature environment, the chiller can maintain the constant temperature of the liquid between 25°C and 26°C or slightly below this range. This adjusts the ink temperature passing through ink tube 2 to be slightly below 25°C to 26°C. As the ink flows into the printhead, the surrounding high temperature causes the ink temperature to rise to a certain level, reaching the printhead at 25°C to 26°C, thus meeting the ink printing temperature requirements. When used in a low-temperature environment, the chiller can maintain the constant temperature of the liquid between 25°C and 26°C. This adjusts the ink temperature passing through ink tube 2 to be slightly above 25°C to 26°C. As the ink flows into the printhead, the surrounding low temperature causes the ink temperature to drop to a certain level, reaching the printhead at 25°C to 26°C, thus meeting the ink printing temperature requirements.

[0025] It should be noted that chillers are existing industrial products that can cool constant-temperature liquids to the required temperature before outputting them, or they can heat constant-temperature liquids to the required temperature before outputting them.

[0026] See Figure 1 In this embodiment, both the first end 21 and the second end 22 of the ink tube 2 are equipped with pipe connectors 3 to facilitate communication with the ink tank and the input end of the printing device.

[0027] See Figure 1 Furthermore, the inlet 12 is located at the bottom of the tank 1, and the outlet 13 is located at the top of the tank 1. Thus, when the chiller inputs constant temperature liquid into the chamber 11 of the tank 1 through the inlet 12, the constant temperature liquid can slowly rise from the bottom to the top of the tank 1 until it circulates back into the chiller through the outlet 13 at the top of the tank 1. This ensures that the liquid in the chamber 11 is kept at full capacity, thereby better enveloping the ink tube 2 in the chamber 11 completely in constant temperature liquid, and thus quickly adjusting the temperature of the ink.

[0028] See Figure 2 Furthermore, the portion of the ink tube 2 placed inside the chamber 11 has a multi-segment curved structure. This extends the path of the ink flowing through the ink tube 2 within the limited space of the chamber 11, and increases the time the ink stays in the ink tube 2, thereby further improving the efficiency of the constant temperature liquid in regulating the ink temperature.

[0029] See Figures 2-3Furthermore, the multi-segment curved structure can be a spiral columnar structure, which minimizes the space occupied by a single ink tube 2 in the chamber 11 while meeting the ink temperature control requirements. The number of ink tubes 2 is several, and several spiral columnar ink tubes 2 are arranged vertically in the chamber 11. The first end 21 of each ink tube 2 is connected to the ink tank of a certain color ink, so that an ink temperature control device can simultaneously adjust the temperature of different colors of ink required by the printing equipment, improving the temperature control efficiency, simplifying the structure and saving costs.

[0030] Furthermore, the outer wall of tank 1 is provided with thermal insulation material (not shown in the figure), which can reduce the influence of the external environment on the temperature of the constant-temperature liquid, thereby saving energy.

[0031] Furthermore, the first end 21 and the second end 22 of the ink tube 2 are both located on the same side of the tank body 1, that is, the first end 21 and the second end 22 of the ink tube 2 are close together, so that the ink enters and flows out at the same end of the ink tube 2, which can further increase the path of the ink tube 2 within the chamber 11. In this embodiment, the first end 21 and the second end 22 can both be located at the top of the tank body 1.

[0032] Furthermore, a fixing part 14 is provided on the outside of the tank body 1. The fixing part 14 can facilitate fixing the tank body 1 to the equipment, thereby preventing the tank body 1 from collapsing or shifting. Specifically, the fixing part 14 is located at the bottom of the side wall of the tank body 1, so that the tank body 1 can be fixed to the placement platform, and the fixing part 14 can be prevented from protruding in space to avoid collision.

[0033] See Figure 2 Specifically, the tank body 1 includes a bottom plate 1b, a side plate 1a mounted on the bottom plate 1b, and a top plate 1c connected to the side plate 1a and positioned opposite the bottom plate 1b. The bottom plate 1b, side plate 1a, and top plate 1c form a chamber 11. The first end 21 and the second end 22 of the ink tube 2 extend out of the chamber 11 from the top plate 1c, thus facilitating the installation of the ink tube 2 within the chamber 11. During installation, the side plate 1a can be installed first on the bottom plate 1b, and after the first end 21 and the second end 22 of the ink tube 2 are inserted through the top plate 1c, the top plate 1c is then closed to cover the side plate 1a.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
