[0022] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the embodiments and features of the embodiments of the present invention may be combined unless they conflict. For ease of description, the words "upper," "lower," "left," and "right" appear below merely to indicate the directions of upper, lower, left, and right in the accompanying drawings and do not limit the structure.

[0023] Example 1

[0024] like Figure 1 As shown, a battery coating printing ink supply system provided in this embodiment includes a first ink barrel 1, a first ink barrel cover 4, a first liquid level gauge 5, a first ink suction tube 14, a stirring device 100 and a lifting mechanism 101.

[0025] The first ink barrel 1 is a standard barrel, and the barrel cover is removed before use. The stirring device 100 includes a first ink barrel cover 4 that is lifted relative to the first ink barrel 1 by a lifting mechanism 101 and a first stirring mechanism 102 that is lifted together with the first ink barrel cover 4.

[0026] The lifting mechanism 101 includes a frame 31 , a slide rail 2 , a proximity switch 3 , a counterweight 7 , a chain 8 , a seat bearing 9 , a sprocket 10 , a first coupling 11 , a lifting motor 12 and a mounting frame 30 .

[0027] The bottom of the frame 31 is provided with a mounting base 311 for securing the first ink barrel 1. The mounting base 311 is U-shaped when viewed from above. The U-shaped opening allows for the entry and exit of the first ink barrel 1, and the U-shaped sidewalls are used to retain the first ink barrel 1. The frame 31 extends vertically and has slide rails 2 provided on its outer surface. The mounting bracket 30 is slidably connected to the slide rails 2. The stirring device 100 and the first ink barrel cover 4 are connected to the mounting bracket 30.

[0028] The lifting motor 12 is mounted on the top of the frame 31, and a sprocket 10 is mounted on its motor shaft via a first coupling 11. The central axis of the sprocket 10, at the end away from the motor shaft, is mounted on the top of the frame 31 via a seated bearing 9. The seated bearing 9 provides rotational support for the sprocket 10.

[0029] The chain 8 is engaged with the sprocket 10, and one end of the chain 8 is connected to the mounting frame 30, and the other end is connected to the counterweight 7. Both ends of the counterweight 7 are adapted to the slide grooves provided on the frame 31. The counterweight 7 provides counterweight for the first ink barrel 1 to rise and fall.

[0030] The lifting motor 12 rotates to drive the chain 8, thereby raising and lowering the mounting frame 30, the first stirring mechanism 102 thereon, and the first ink barrel cover 4. The proximity switch 3, mounted on the frame 31, is used to determine the lowering limit of the mounting frame 30. When the mounting frame 30 descends and triggers the proximity switch 3, the first ink barrel cover 4 is closed on the first ink barrel 1, and the first dispersion disc 15 of the stirring device 100 is placed in the first ink barrel 1.

[0031] The first stirring mechanism 102 includes a first stirring motor 6, a second coupling 13, a first dispersion disc 15, and a first connecting shaft 16. The first stirring motor 6 is mounted on the first ink barrel cover 4. Its motor shaft passes through the first ink barrel cover 4 and is connected to the first connecting shaft 16 via the second coupling 13. The first dispersion disc 15 is fixed to the first connecting shaft 16 via a key. The rotation of the first stirring motor 6 drives the first dispersion disc 15 to stir the ink in the first ink barrel 1. To ensure sufficient stirring, the first dispersion disc 15 is equipped with multiple stirring teeth 151 arranged in an upper and lower staggered pattern along its circumference.

[0032] The first liquid level gauge 5, an ultrasonic liquid level gauge, is mounted on the first ink barrel cover 4 and is used to measure the ink volume within the barrel. A first ink suction tube 14 is provided on the first ink barrel cover 4 and extends into the first ink barrel 1. This first ink suction tube 14 is used to draw ink from the first ink barrel cover 4. In this embodiment, only the stirring device 100 and the first ink barrel 1 can be used, and the first ink suction tube 14 is directly connected to the printer. The first ink suction tube 14 is connected to a diaphragm pump 17, which draws ink from the ink barrel.

[0033] During use, a forklift is used to transport the first ink barrel 1 filled with ink, removing the barrel lid before delivery. The lifting mechanism 101 is activated to lower the first ink barrel lid 4 and the first stirring mechanism 102 until the proximity switch 3 is triggered to stop the lifting motor 12. The first stirring motor 6 is activated, driving the first dispersion plate 15 to rotate and stir the ink. Once completed, the first ink suction pipe 14 is activated to aspirate the ink, and the liquid level in the barrel is monitored using the first liquid level gauge 5.

[0034] Example 2

[0035] The first embodiment is repeated, except that the ink supply system for printing on a battery coating in this embodiment further includes a sub-packaging device 200.

[0036] The capacity of the second ink barrel 21 is smaller than that of the first ink barrel 1 . The small-capacity subpackaging is more suitable for monitoring the ink status, is more conducive to heating, and makes the heating efficiency more obvious.

[0037] The second stirring mechanism 201 includes a second stirring motor 26 installed on the second ink barrel cover 19, a second connecting shaft 27 connected to the motor shaft of the second stirring motor 26, and a second dispersing disk 29 fixed on the second connecting shaft 27, and the second dispersing disk 29 extends into the second ink barrel 21.

[0038] The second ink barrel 21 has an opening at its bottom, where a first pipe 202 and a second pipe 203 are located. The first pipe 202 is connected to the first ink suction pipe 14 via a diaphragm pump 17. An electrically controlled valve 24 is provided on the first pipe 202 to control the opening and closing of the first ink suction pipe 14. A ball valve 25 is provided on the second pipe 203 to drain the rinse water from the second ink barrel 21.

[0039] The inner surface of the second ink barrel 21 is equipped with a heating belt 23 (purchased and electrically heated). A thermocouple 20 for monitoring ink temperature is connected to the lower end of the second ink barrel cover 19. This plug-in thermocouple 20 is used to monitor the ink temperature and control the start and stop of the heating belt 23. A second level gauge 18 is also provided on the second ink barrel cover 19 to measure the ink volume within the second ink barrel 21.

[0040] The second ink barrel cover 19 is provided with a second ink suction tube 28 extending toward the second ink barrel 21 , and the second ink suction tube 28 is connected to the printer.

[0041] The second ink barrel 21 is provided with a buckle 22 for fixing the second ink barrel cover 19 to lock and seal the ink barrel.

[0042] The packaging device 200 not only stirs the ink but also heats the ink.

[0043] In this embodiment, ink in the first ink barrel 1 is transferred from the first ink suction tube 14 and the first pipeline 202 to the second ink barrel 21 via the diaphragm pump 17. Normally, the dispensing device 200 has the second ink barrel cover 19 closed within the second ink barrel 21. The ink is stirred and heated within the second ink barrel 21, and its temperature is monitored by the thermocouple 20. Once the ink reaches the desired temperature, it is delivered to the printer via the second ink suction tube 28.
