[0006] 1. The reciprocating action of adding ink will bring tiny air bubbles into the ink, and the accumulation of these air bubbles and a small amount of air bubbles entering the print
cartridge from the print head will gradually foam the ink, resulting in bubble failures in the printer;
[0007] 2. It is easy to add ink of different colors by mistake;
[0008] 3. When adding ink, it is easy to cause ink splash
pollution. During the ink filling process, if the staff is slightly careless, it is easy to cause ink splashing, dumping, and overflowing, resulting in
pollution of the surrounding environment;
[0009] 4. In the process of adding ink in a non-vacuum environment, microorganisms are easy to
breed, making the ink easy to rot and deteriorate, resulting in shortened
shelf life of the ink, and even causing plugging and color casts;
[0010] 5. There is no prompt alarm system when the ink is used up, and it is very inconvenient to rely on people to watch it at any time
[0013] 2. Ordinary soft bags pack ink to prevent ink overflow. A
silicone plug will be added to the
nozzle of the ink bag. When a
metal needle is inserted into the
nozzle of the ink bag, the
silicone plug needs to be pierced. A small amount of
silicone shavings will be mixed into the ink, and there will be Clogged or not smooth phenomenon;
[0014] 3. When replacing the ink bag, the sharp
metal pins are easy to pierce the ink bag, so that the ink flows everywhere
The defect of this continuous supply system is that it applies the principle of air pressure, that is to say, it provides a non-vacuum ink supply environment, which will bring many problems caused by the non-vacuum environment ink supply we mentioned earlier. question
[0018] The sensors that monitor the change of the liquid level are all immersed in the ink to work. In this way, another hidden danger caused by the long-term immersion of the components appears. Various anions and cations in the ink will corrode the components to varying degrees, and The colorant in the ink is also very easy to deposit on the component. The deposited colorant will grow a deposition layer on the component. These deposits will fall off into the ink and easily block the
nozzle; moreover, the sensitivity of the sensor with the deposition layer is low. will be greatly reduced, which will affect the alarm effect and bring inconvenience to practical application
[0019] At present, in addition to daily small-scale commercial printers, there are also printers for large-format printing and
dyeing. Such printers for large-format printing and
dyeing use a large amount of ink and frequently replace ink, and printers generally used for large-format printing and
dyeing are bulky. The ink
cartridge is placed vertically on the top of the printer. When replacing the ink
cartridge, it is often necessary to operate on the top of the printer. It is necessary to keep the vertical direction aligned with the
insertion port to insert a new ink bag. The operation position is high, and the operation is time-consuming and laborious.
[0020] In addition, in the existing continuous ink supply device, when it is necessary to replace the liquid in the ink bag, only the entire ink bag can be replaced. At the same time, when the ink bag is in use, the ink in the ink bag often remains. On the one hand, it causes waste of materials; on the other hand, it is quite troublesome to deal with the remaining ink. If it is not handled well, it will cause environmental
pollution and cause a lot of waste.
