Technical Field

The invention relates to the technical field of ink-jet printing equipment, in particular to an ink absorption device of a printing nozzle.

Background

When a printing nozzle of an ink jet printer performs printing, due to different shapes and colors of patterns, the use frequency of each spray hole is different, so that part of the spray holes are dried to cause spray hole blockage, or the spray holes are wet and often stained with dust in the air to cause the spray hole blockage in the printing process. When the jam of orifice appears in the printing process, need press the china ink in order to dredge the orifice to the shower nozzle at the printing in-process, the shower nozzle surface can persist ink or the dry particulate matter that ties after pressing the china ink, for avoiding remaining the ink influence to print the quality, need can reprint after the ink clean up on shower nozzle surface.

A nozzle cleaning device in the prior art is generally a contact type cleaning device, and for example, a wiping maintenance device for an inkjet printer disclosed in chinese patent CN203543368U includes a bracket, a wiping device, a maintenance device, and a control system, and is characterized in that the wiping device is disposed on one side of a printing area, and a motor is directly connected to drive a wiping blade to rotate, and the wiping blade is rotationally immersed in a cleaning solution to be cleaned after wiping a nozzle. Although the nozzle cleaning device in the prior art can achieve the functions of scraping ink and moisturizing, the nozzle cleaning device in the prior art has the following problems: by adopting a contact type cleaning mode of scraping the nozzle by the ink scraping sheet, particles at other parts are easily scraped into other spray holes, so that the normal spray holes are blocked, and the service life of the nozzle is influenced; when patterns with various colors are printed, the adjacent two longitudinal rows of nozzles usually print ink with different colors, when the nozzles are scraped by a doctor blade, color mixing at the spray holes of the two longitudinal rows of nozzles is easily generated, although the ink scraping blade scrapes the nozzles and then rotates and immerses the nozzles into cleaning liquid for cleaning, the cleaning liquid is polluted by the ink along with too many cleaning times, and the ink mixing at the spray holes is also caused when the ink is scraped again, so that the next printing task is influenced; the ink scraping sheet rotates to enter cleaning liquid for cleaning after scraping the nozzle, then rotates out for next ink scraping, and the interval time between two adjacent ink scraping is long, so that the printing efficiency is influenced.

In order to solve the above problems, the prior art discloses a non-contact type nozzle cleaning device, such as a water spraying vacuum adsorption device disclosed in chinese patent CN205705760, which comprises a main body, wherein a vacuum adsorption groove and a residual ink channel are arranged on the main body, the main body is further provided with a water spraying channel and a recovery channel, the water spraying channel is a rectangular groove parallel to the vacuum adsorption grass, a water spraying pore channel is arranged in the middle of the water spraying channel, a recovery water pore channel is arranged in the recovery channel, the recovery water pore channel is arranged on an end extension line of the water spraying channel, the residual ink channel is communicated with the water pore channel, the device sprays water to clean the nozzle, and simultaneously performs vacuum adsorption on the ink at the lower end of the nozzle, so as to enhance the cleaning effect; another example of the nozzle maintenance device disclosed in chinese patent CN213649136U is a device including an ink removing mechanism; the ink removing mechanism comprises a support, an ink absorbing assembly and an ink scraping sheet, the ink absorbing assembly is mounted on the support, the ink removing mechanism is provided with an ink guide channel, one end of the ink guide channel penetrates through the top of the ink absorbing assembly to form an ink absorbing port, and the other end of the ink guide channel penetrates through the ink absorbing assembly and the support in sequence to form an ink outlet; the ink scraping sheet is arranged close to the ink absorption port, at least part of the ink scraping sheet protrudes out of the top of the ink absorption assembly, and the spray head sequentially passes through the ink absorption port and the ink scraping sheet in the cleaning process of the spray head; in the process, the ink absorbing port is in a negative pressure state under the action of an air suction device outside the ink removing mechanism, so that ink on the surface of the spray head is absorbed and gathered into an ink drop shape, most of the ink in the ink drop state is absorbed, and then a small amount of ink is left by scraping the part of the ink scraping piece protruding out of the ink absorbing component.

Although the problem of normal orifice blockage or color cross in contact cleaning is avoided in the prior art, a certain vacuum degree can be generated only by a very small distance between the adsorption device and the spray head in a vacuum adsorption mode, so that the adsorption effect is good. The height of a spray head of an actual printer can be finely adjusted along with the difference of the thickness of a printing medium, in the prior art disclosed by the Chinese patent CN205705760, the height of a main body is not adjustable, in the prior art disclosed by the Chinese patent CN213649136U, the overall height of an ink absorption assembly is adjusted through a driving assembly, and when the height of the spray head is finely adjusted due to the difference of the thickness of the printing medium such as paper, the driving device cannot adjust the height by the order of magnitude of the minute, so that a good vacuum degree cannot be formed between the spray heads by an adsorption device, and the cleaning effect of the spray head is influenced; because machining error and assembly error lead to the different shower nozzle height on the same bottom plate to have little difference, each shower nozzle also can have little inclination for the printing medium face to the horizontal position of the shower nozzle of same vertical row also can have little deviation, above-mentioned prior art can't the height, inclination and the horizontal position of each shower nozzle of self-adaptation, lead to the clearance effect poor.

In summary, the prior art has the following problems:

1) the contact cleaning mode is easy to scrape the particles at other parts into the normal spray holes, so that the normal spray holes are blocked, and the service life of the spray head is influenced; cross color can occur when printing ink with various colors; the time interval between two adjacent ink scraping is long, so that the printing efficiency is influenced;

2) the height, the inclination angle and the transverse position of the non-contact cleaning mode, which cannot be self-adaptive to the spray head, cause poor cleaning effect and influence on subsequent printing quality.
