ink scraping device for a printer

Abstract

The invention discloses an ink scraping unit for printers. The ink scraping unit comprises a support fixedly connected with a frame of a printer. A scraper holder capable of sliding back and forth on the support is disposed on the support. A scraper is disposed inside the scraper holder. A drive mechanism driving the scraper holder to slide back and forth on the support is also disposed on the support. The drive mechanism comprises a steering device arranged on one side of the support and a crank fixedly connected with an output shaft of the steering device. A link is hinged to the other end of the crank. The other end of the link is hinged to the scraper holder. The position of the scraper can be located accurately with no error, the control principle is simple and reliable, and the scraper can thoroughly scrape residual ink on a nozzle of the printer.

Description

【Technical field】 [0001] The invention relates to a printer, more specifically to an ink scraping device of the printer. 【Background technique】 [0002] When the printer starts to print, it needs to clean the nozzle of the printer. Before cleaning, it is necessary to scrape off the residual ink on the nozzle of the printer. The ink scraping method of the traditional printer is: the motor drives the scraper seat to slide back and forth on the bracket, when the scraper seat and the scraper in it slide to the bottom of the printer nozzle, start the inkjet trolley equipped with the printer nozzle on the printer. During the horizontal movement, the nozzle of the printer touches the scraper in the scraper seat, and the scraper scrapes off the residual ink on the nozzle. However, this traditional way of wiping ink has the following disadvantages: the motor that drives the scraper seat to slide back and forth controls the stop position of the scraper seat after sliding through two ...

Problems solved by technology

However, this traditional way of wiping ink has the following disadvantages: the motor that drives the scraper seat to slide back and forth controls the stop position of the scraper seat after sliding through two grating nodes. Such a scraping device is applied to motors, screw rods, Structural components such as gratings make the structure of the ink scraping device complex, the control system is cumbersome, and unfortunately, the positioning accuracy of the scraper seat and the scraper stop position is low, and it is easy to cause position deviation and the ink scraping cannot be completed well. Moreover, the scraping Once the printer is powered off when the film seat is sliding, when the printer is powered on again, the scraper seat cannot automatically return to the initial position. When scraping ink, it is necessary to manually adjust the position of the scraper seat and the scraper, which reduces efficiency and increases If you forget to adjust the position of the scraper seat manually, it may even cause an accident that the scraper seat collides with the inkjet trolley, thus damaging the machine
