Embodiment Construction
[0059] In the current technical field of the ink tube heating system, in order to heat the ink in the ink tube and make it easy to work, the method of winding the heating wire on the ink tube is often used. However, this method cannot guarantee The ink in the ink tube is always kept at a constant temperature. The temperature of the ink in the ink tube where the heating wire is wound will change instantaneously due to the instantaneous heating and cooling of the heating wire. As a result, the best performance of the ink cannot be guaranteed; the heating wire outside the ink tube is a metal wire. If the inkjet printer causes ink leakage in the ink tube due to external impact, the ink inside the ink tube will leak, and the heating wire will be easily corroded. Compromising the safety of the ink supply system in inkjet printers. In addition, in order to monitor the temperature of the ink in the ink tube in real time, it is necessary to install a temperature sensor in the ink tube ...

The invention provides an ink tube heating system and an ink tube heating method. The ink tube heating system comprises a constant-temperature liquid tank, a control device, a heating tube and at least one ink tube, wherein the heating tube is positioned outside the ink tube and is used for heating ink in the ink tube; an inner cavity of the heating tube communicates with the constant-temperatureliquid tank; liquid in the constant-temperature liquid tank flows into the inner cavity of the heating tube; a heating piece and a temperature measuring piece are arranged in the constant-temperatureliquid tank; and the heating piece and the temperature measuring piece are electrically connected with the control device. The ink tube heating method comprises the following steps of firstly, duringheating, injecting liquid into the constant-temperature liquid tank; secondly, controlling the actual liquid level in the constant-temperature liquid tank according to a preset liquid level; thirdly,controlling the actual liquid temperature in the constant-temperature liquid tank according to the preset temperature; controlling a driving device to drive the liquid in the constant-temperature liquid tank and the liquid in the heating tube to flow circularly; and finally, heating the ink tube by the heating tube. According to the ink tube heating system and the ink tube heating method, the inkcan be effectively heated, constant-temperature control of the ink is realized, the ink supply stability of an ink supply system is improved, and the working performance of an ink-jet printer is improved.
Description
technical field [0001] The invention relates to the technical field of inkjet printing machines, in particular to an ink tube heating system and an ink tube heating method. Background technique [0002] Printers have become one of the indispensable office equipment for work and study in modern society. Inkjet printers occupy a pivotal position in the printer market. Ink is the substance used to form pictures, characters and information in inkjet printing. In order to ensure the printing quality of the inkjet printer, it should be ensured that the ink maintains a certain viscosity in the ink tube, that is, maintains a certain fluidity. Ink viscosity control depends on controlling the temperature of the ink in the ink tube. [0003] At this stage, in order to keep the temperature of the ink within a certain range, a heating wire is wound on each ink tube, and a temperature control board is installed for the heating wire, and several temperature sensors are installed inside ea...
