Referring to Figures 2 to 8 look at the operation of the taping device for an ink cartridge according to a preferred embodiment of the present invention. The operation process of the taping machine for an ink cartridge of the present invention largely consists of a tape supply process, a tape sealing process, and a tape cutting process.

The tape feeding process is to move the tape sandwiched between the tape guides under the rib of the rotator. That is, when the user presses the pedal in the initial state shown in FIGS. 2 and 3, the cylinder rod 342 of the supporter cylinder 340 is inserted in the solid arrow direction as shown in FIGS. 4 and 5, and the cylinder The nozzle supporter 320 hinged to the rod 342 rotates in the dashed-dotted arrow direction. Then, the crimping nozzle 330 coupled to the nozzle supporter 320 is also rotated in the direction of a dashed-dotted arrow, and a negative pressure is generated at the crimping nozzle 330 and the end protrudes to tape 430. The bottom surface of the rotator 310 is in close contact with the bottom of the rib 314. 6 and 7, the nozzle supporter 320 and the pressing nozzle 330 are returned to their original positions, and thus the tape adhered to the bottom surface of the rib 314 by the pressing nozzle 330. 430 is unfolded in a horizontal state below the rib 314 of the rotator 310.

The tape sealing process is a process of sealing the tape on the head surface by mounting the ink cartridge to the cartridge frame. That is, as shown in FIG. 7, when the ink cartridge 800 is mounted on the cartridge frame 510, the contact switch 520 outputs a cartridge mounting signal. Subsequently, the control circuit of the control box 710 supplies air to the piston cylinder 230 in response to the cartridge mounting signal. Accordingly, as the piston 220 descends, the pressing rubber 226 at the lower end of the piston 220 presses the tape 430 downward so as to closely adhere to the head 810 surface of the ink cartridge 800.

The tape cutting process is a process of cutting the tape 430 in the ink cartridge 800 where the tape is sealed. After the tape sealing is completed as shown in FIG. 8, the piston 220 moves upward. Then, one end of the tape 430 in close contact with the ink cartridge 800 is cut, and the ink cartridge 800 is removed from the cartridge frame 510. The tape cutting process may be performed manually by a user, but may be automatically performed by attaching a separate cutting means according to the application of the present invention.

As described above, the taping device for an ink cartridge according to the embodiment of the present invention presses a tape continuously supplied by a piston to closely contact the head surface of the ink cartridge, thereby preventing foreign substances from entering the nozzle of the ink cartridge when sealing the tape. In addition, the sealing process of the tape is automatically performed at a high speed, thereby increasing the regeneration efficiency and productivity of the ink cartridge.
