[0002] Chinese patent document CN212098006U discloses an ink supply device for a digital printing machine, which includes a mounting frame. A storage tank and an ink supply tank are welded to the top of the mounting frame. A micro pump is fixed to the inner top wall of the mounting frame by bolts. The input end of the micro pump is communicated with a first conduit, and the other end of the first conduit is communicated with the storage tank. A driving motor can drive a stirring frame to rotate in the storage tank through a stirring rod to stir the ink, which can prevent the ink from accumulating and causing blockage. A heater can heat the heating liquid in the inner cavity through a heating rod, so that the ink in the ink supply tank is heated and kept warm, realizing that the ink can be suitable for dyes of different properties and ensuring the transfer effect. At the same time, a protective cover is provided to play a protective role and extend the service life of the device.

[0003] However, in the above device, the micro pump is located below the device, and the stirring before ink supply cannot act on the ink remaining near the micro pump, and the extracted ink is not heated. After the machine has not been used for a long time and stops supplying ink, the initially extracted ink contains more solid particles due to precipitation. Over time, it will block the micro pump. Therefore, we propose an ink supply device for a digital printing machine. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an ink supply device for a digital printing machine, which can solve the problem that the ink extracted by some existing devices still causes precipitation and blockage.

The ink extraction tube is fixedly installed on the inner top of the ink supply tank, the micro pump is fixedly installed on the top of the ink supply tank, the electric heating rod is wound around the ink extraction tube, and one end of the ink extraction tube penetrates through the top of the ink supply tank and is communicated with the input end of the micro pump.

[0009] Preferably, the ink supply mechanism further includes a power cord, an ink inlet pipe, and a connecting piece. A power cord is fixedly installed on the outer surface of one side of the ink supply tank. The power cord is electrically connected to the heating rod. An ink inlet pipe is fixedly installed on the outer surface of one side of the micro pump. One end of the ink inlet pipe communicates with the output end of the micro pump, and the other end of the ink inlet pipe is fixedly installed with a connecting piece.

[0010] Preferably, the stirring mechanism includes a servo motor, a rotating shaft, and stirring rods. A servo motor is fixedly installed on the top of the ink supply tank. The rotating shaft is rotatably installed on the inner top of the ink supply tank. The rotating shaft of the servo motor is drivingly connected to the rotating shaft. At least two groups of stirring rods are fixedly installed on the outer surface of the rotating shaft.

[0011] Preferably, a refilling pipe communicating with the inside is fixedly installed on the front outer surface of the ink supply tank. A sealing cap is threadedly installed at one end of the refilling pipe.

[0012] Preferably, a liquid level sensor is fixedly installed on the inner bottom of the ink supply tank. Through the liquid level sensor, the remaining amount of ink can be monitored, and by connecting with the digital printing machine, the user can obtain the remaining amount data on the digital printing machine.

[0013] Preferably, an installation hole is formed through the front side of the ink supply tank, and a liquid level window is inlaid in the installation hole.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] (1). For the ink supply device for the digital printing machine, through the ink supply mechanism, first, the micro pump is arranged on the top of the ink supply tank, so that there is no deposition of ink that cannot be acted on near the micro pump, and the ink to be pumped by the micro pump is heated by the heating rod before being pumped. After each ink supply, the ink in the ink supply path in front of the micro pump, that is, inside the ink supply tank, will be stirred, and the ink in the ink extraction pipe will be heated, so that the ink can be fully processed and blockage can be avoided. This solves the problem that in some existing devices, the micro pump is located below the device, and the stirring before ink supply cannot act on the ink remaining near the micro pump, and the extracted ink is not heated. As a result, after the machine has not been used for a long time and stops supplying ink, the initially extracted ink contains more solid particles due to precipitation, and over time, it will block the micro pump, improving the practicability of the device.
