Description

Film attachment device of printer cartridge

The present invention relates to a cartridge film applying apparatus that is used to seal an ink inlet with a film after injecting ink into a cartridge for an ink jet printer.

The present invention relates to a cartridge film attaching device including a vacuum container and a vacuum pump to prevent air from flowing into a cartridge during a cartridge film attaching operation, and a heat fusion device for fast and reliable bonding of the film. .

Recently used printers include ink jet printing by spraying liquid ink and laser jet printing by spraying powder toner. The ink jet printing method uses liquid ink to produce various colors. It is mainly used in color printers because of its advantages.

Meanwhile, in the ink jet printer, the liquid ink is contained in a small container called a cartridge, and the cartridge is formed with an ink inlet 41 and an air inlet 42 formed thereon, as shown in FIG. While the ink is injected into the cartridge 40 through the air inlet 42 to maintain a constant internal pressure of the cartridge to allow a sufficient amount of ink to be injected into the cartridge 40, After the ink is sufficiently injected as described above, the film 90 is bonded to the upper portion of the ink so that the injected ink does not leak to the outside through the ink inlet 41 or the air inlet 42.

However, in the related art, since ink is injected into the cartridge 40 and then the film 90 is adhered to the upper portion thereof under atmospheric pressure, a considerable amount of air is mixed with the ink in the cartridge 40. Therefore, when the cartridge in such a state is applied to the printer, the ink is injected with the air at the time of printing, the concentration of the printing ink is uneven, there is a problem that the print state is poor.

In addition, the air contained in the cartridge oxidizes or hardens the ink early, so there is a problem that the life of the ink is shortened, and when using the cartridge in this state, there is also a problem that the printer nozzle is easy to be clogged.

In order to solve the above problems, the present invention is completed by injecting ink into the cartridge and then attaching a film to the upper portion to seal the ink inlet. By preventing air from flowing into the cartridge at all, the ink state can be used for a long time without deterioration, and the printer nozzle is prevented from occurring while maintaining a good printing state.

In addition, the film is attached to the adhesive tape by a heat fusion method so that the film does not fall with a moderate force, thereby improving durability.

As a solution according to the present invention, when the film is placed on the top of the cartridge in which the ink is injected by the film clamp cylinder and the film guide cylinder, the fusion unit operation cylinder is lowered so that the film is heat-sealed on the upper surface of the cartridge by the fusion unit. So that the film can be firmly attached,

As the film attaching process is performed inside the vacuum container, a small amount of air is not mixed in the completed cartridge.

Hereinafter, with reference to the accompanying drawings, the configuration and operation and the like will be described in detail.
