In order to ensure the accuracy of the measurement results, the ink needs to be stirred by a special stirring device. The existing stirring device includes a tank body and a stirring assembly. The stirring assembly includes a driving member, a rotating shaft and a stirring rod arranged on the rotating shaft. The driving member is installed at the bottom of the tank body to drive the rotating shaft to rotate axially to stir the ink in the tank body evenly.

[0038] The embodiments of the present invention are written in a progressive manner.

[0039] like Figure 1 As shown, an embodiment of the present invention provides a stirring device for ink viscosity testing, comprising: an outer shell 1 with a built-in accommodating chamber, a heating element 21 is provided on the inner wall of the accommodating chamber; a magnetic stirring seat 3 is arranged at the bottom of the accommodating chamber; an inner shell 4 is detachably mounted in the accommodating chamber, and a chamber for accommodating ink is provided in the inner shell 4; a magnetic rotor 5 is arranged in the chamber, and the magnetic rotor 5 can be triggered by the magnetic stirring seat 3 to rotate to stir the ink.

[0040] The existing stirring device includes a tank body and a stirring assembly. The stirring assembly includes a drive member, a rotating shaft, and a stirring rod mounted on the rotating shaft. The drive member is mounted on the bottom of the tank body and drives the rotating shaft to rotate axially to stir the ink in the tank body. However, this stirring device has a complex structure, and the stirring assembly is fixed to the tank body. After testing one ink, the entire stirring device needs to be cleaned before testing the next ink. This complex cleaning process reduces testing efficiency.

[0041] To address the aforementioned technical problems, the present invention provides a stirring device for ink viscosity testing. The device comprises an outer shell 1, a heating element 21, and an inner shell 4. The outer shell 1 defines a chamber, the bottom of which is provided with a magnetic stirring base 3. The inner shell 4 is fitted within the outer shell 1 and rests on the magnetic stirring base 3. The inner shell 4 defines a chamber for accommodating ink. A heating element 21 is disposed on the inner wall of the chamber, which heats the inner shell 4 and the ink within it. A magnetic rotor 5 is disposed within the chamber, which is triggered by the magnetic stirring base 3 to rotate and thereby stir the ink. While the heating element 21 heats the ink, the magnetic rotor 5 stirs the ink within the chamber, thereby achieving a more uniform ink temperature. Furthermore, since the magnetic rotor 5 is not in direct contact with the magnetic stirring base 3, after testing one ink, the inner shell 4 can be replaced with a new one to test another, or the inner shell 4 can be cleaned, making cleaning more convenient and efficient. It can be seen that, compared with the prior art, the stirring device for ink viscosity testing in the embodiment of the present invention has a simple structure and can greatly improve the efficiency of ink viscosity testing.

[0042] The magnetic stirrer 3 is driven by a micromotor to rotate a magnet. The rotating magnetic field generated by the magnet drives the magnetic rotor 5, thereby stirring the ink in the chamber. The magnetic stirrer 3 and the magnetic rotor 5 are driven by the magnetic field. After testing an ink, the inner housing 4 can be replaced directly without replacing the entire testing device, making it more convenient.

[0043] In the above structure, as one embodiment, the rotation speed of the magnetic rotor 5 in the embodiment of the present invention is specifically 100 rpm-1000 rpm, which can quickly stir the ink evenly.

[0044] In the above structure, as one embodiment, the heating element 21 in the embodiment of the present invention is used to heat the inner shell 4. The ink temperature is affected by factors such as temperature, pressure, and shear rate. Since the viscosity of the ink is greatly affected by temperature, the temperature needs to be kept stable during the measurement process. According to national standards, during the measurement process, the temperature of the ink needs to be adjusted to 25±0.2°C. As one embodiment, the stirring device for ink viscosity testing in the embodiment of the present invention also includes: a temperature detector 22 and a temperature controller, wherein the temperature detector 22 is used to detect the temperature inside the inner shell 4, and the temperature controller is connected to the temperature detector 22. The temperature controller is used to receive the temperature value detected by the temperature detector 22, and the temperature controller is connected to the heating element 21. When the temperature value detected by the temperature detector 22 is less than the preset temperature range, the heating element 21 continues to heat. When the temperature value detected by the temperature detector 22 meets the preset temperature range, the heating element 21 is controlled to stop heating. This is more intelligent and easier to operate manually. The preset temperature range here is specifically 25±0.2°C.

[0045] In the above structure, as one specific implementation method, the heating element 21 in the embodiment of the present invention is specifically a heating wire.

[0046] Furthermore, in order to avoid uneven temperature, as one preferred embodiment, a heating medium is provided between the outer shell 1 and the inner shell 4 in the embodiment of the present invention. The inner shell 4 is heated by the heating medium to avoid local overheating.

[0047] Furthermore, in the above structure, in order to facilitate the operator to know whether the conditions for testing viscosity are met, as one of the preferred implementations, the stirring device for ink viscosity testing in the embodiment of the utility model also includes a display panel 6, wherein the display panel 6 is arranged on the outer surface of the outer shell 1, and the display panel 6 is connected to the temperature detector 22, and the real-time temperature detected by the temperature detector 22 is displayed through the display panel 6.

[0048] Furthermore, the temperature detector 22 in the embodiment of the present invention is specifically a temperature sensor.

[0049] Furthermore, as one of the implementation methods, the stirring device for ink viscosity testing in the embodiment of the present invention also includes a power cord, which is used for external power supply and is also connected to the magnetic stirring seat 3 and the heating element 21.

[0050] Furthermore, as another embodiment, the stirring device for ink viscosity testing in the embodiment of the present invention further includes a battery 7, which is disposed within the housing 1 and is used to connect to the display panel 6, and the electromagnetic stirrer and the heating element 21. The battery 7 makes the device more convenient to carry and use.

[0051] Furthermore, as one of the embodiments, the stirring device for ink viscosity testing in the embodiment of the utility model also includes a charging interface 71, which is arranged on the housing 1. The charging interface 71 is connected to an external power source through a charging cable to charge the battery 7.

[0052] Furthermore, as one of the embodiments, the stirring device for ink viscosity testing in the embodiment of the present invention also includes an upper cover 41 and a pressure-maintaining valve 42, wherein the upper cover 41 is arranged on the top of the inner shell 4, and the pressure-maintaining valve 42 is arranged on the upper cover 41. When the ink is heated, the air pressure in the chamber increases, and the pressure-maintaining valve 42 is arranged on the upper cover 41 to keep the air pressure in the chamber within a certain range, thereby avoiding the influence of the air pressure in the chamber on the ink viscosity test results.

[0053] The temperature detector 22 can be used to directly or indirectly detect the temperature of the ink. As one embodiment, the temperature detector 22 in the embodiment of the present invention is disposed on the inner wall of the outer shell 1, and indirectly detects the temperature of the ink by detecting the temperature of the inner shell. Preferably, the temperature detector 22 is disposed on the bottom surface of the accommodating cavity. In this way, the temperature detector 22 does not need to be cleaned when cleaning the inner shell 4.

[0054] Furthermore, as another implementation, the temperature detector 22 in this embodiment is fixedly disposed below the upper cover 41 , and a testing end of the temperature detector 22 is inserted into the ink to detect the temperature of the ink.

[0055] Furthermore, the temperature detector 22 in this practical embodiment is specifically a thermocouple.

[0056] Furthermore, as one of the implementation modes, the stirring device for ink viscosity testing in the embodiment of the present invention further includes a handle 8, which is arranged on the outer surface of the housing 1, making it easier to operate and carry.

[0057] Furthermore, as one specific implementation method, the handle 8 in the embodiment of the present invention has an open state and a folded state, and the handle 8 is rotatably connected to the housing 1 to switch between the open state and the folded state.

[0058] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
