Inkpot limiting device and multifunctional printer using the same

Abstract

An inkpot limiting device and a multifunctional printer using the same are provided. The multifunctional printer includes a housing and the inkpot limiting device disposed therein. The inkpot limiting device includes a limiting structure, a shaft, a carrier, and a pair of limiting magnets. The limiting structure is disposed on the housing and located in a diameter direction of the shaft. The carrier has a main body portion and a carrying portion and a limiting portion located at opposite sides of the main body portion. The limiting structure and the limiting portion face each other. The limiting magnets include a permanent magnet disposed on one of the limiting structure and the limiting portion and an electromagnet disposed on the other of the limiting structure and the limiting portion. When electricity is applied to the electromagnet, the electromagnet is magnetically attracted to fix with the permanent magnet.

Description

technical field [0001] The present invention relates to an ink box limiting device and a multifunctional machine, in particular to an ink box limiting device using magnetic suction to limit the position of the ink box and a multifunctional machine using the ink box limiting device. Background technique [0002] figure 1 and figure 2 It is a partial schematic diagram of an all-in-one machine in the prior art. Please also refer to figure 1 and figure 2 , the reciprocating printer in the multifunctional all-in-one machine 100 of the prior art is in order to ensure that the ink droplets will not be deposited around the nozzle and cause the nozzle to be blocked, so a scraper that can move relative to the nozzle will be additionally provided in the all-in-one machine 100 110, to scrape off excess ink on the nozzle. [0003] And by figure 1 and figure 2 It can be seen that the ink cartridge carrier 120 is sleeved on the shaft rod 130, and because the structural design bet...

Problems solved by technology

[0003] And by figure 1 and figure 2 It can be seen that the ink cartridge carrier 120 is sleeved on the shaft rod 130, and because the structural design between the limiting structure 140 of the prior art and the limiting portion 122 of the ink cartridge carrier 120 needs to have a tolerance range, otherwise the ink cartridge will be damaged. The size of the limit portion 122 of the carrier and the limit structure 140 are too tightly matched, resulting in excessive resistance when the ink cartridge carrier 122 moves axially along the shaft 130

Also because of the setting of this tolerance range, when the scraper 110 cleans, the scraper 110 will cause the ink cartridge carrier 120 to rotate and be lifted with the shaft 130 as the center of rotation at the same time, and the amount of interference between the nib and the scraper 110 will also decrease. Just change thereupon and can't keep at original design value, like this just can affect the wiping force when scraper 110 cleans ink-jet head, and then cause nozzle clogging
