Description

Technical Field

[0001] This utility model relates to the technical field of ink scraping and moisturizing mechanisms, and in particular to a distributed ink scraping and moisturizing mechanism with flipping function. Background Technology

[0002] An inkjet printer is a printing device that sprays liquid ink into tiny droplets through nozzles and attaches them to paper. Its core technologies are divided into thermal and piezoelectric. Random inkjet printers have become the mainstream due to their simple structure and low cost, which has led to the development of thermal bubble and micro-piezoelectric technologies. The latter improves color accuracy by using room temperature inkjet printing.

[0003] After searching, it was found that most existing ink cartridge printhead scraping devices adopt a separate scraping and protection structure, and only use one scraper. All printheads are scraped by one scraper, which easily leads to dust on the printhead base plate being scraped onto the printhead, increasing the probability of printhead damage. In addition, the scraping effect is generally poor and the efficiency is low. Therefore, a distributed scraping and moisturizing mechanism with flipping is needed to meet people's needs. Utility Model Content

[0004] The purpose of this invention is to provide a distributed, rotating ink-scraping and moisturizing mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a distributed, rotating, ink-scraping and moisturizing mechanism, comprising a housing, a motor disposed on one side of the housing, a transmission link disposed on the output end of the motor, a driven link rotatably connected to one end of the transmission link, and a long link rotatably connected to one end of the driven link, the long link being arranged parallel to the longitudinal direction of the housing, and several rotating shafts rotatably connected inside the housing, each rotating shaft being arranged parallel to the short direction of the housing, the several rotating shafts being evenly distributed along the longitudinal direction of the housing, and each rotating shaft being provided with an ink scraper seat. The two adjacent doctor blade holders are staggered, and the positions of every two doctor blade holders are corresponding. Each doctor blade holder has a pin slidably connected to both sides. A doctor blade is slidably connected from top to bottom inside the doctor blade holder. The two pins are inserted into the two sides of the doctor blade at one end inside the doctor blade holder. A spring plate is connected to the outside side of the pin. A spring is connected between the spring plate and the outer wall of the doctor blade holder. A handle is provided on the outside of the spring plate. A short connecting rod is connected to the outside end of each rotating shaft. Several short connecting rods are arranged in parallel and are rotatably connected to a long connecting rod.

[0006] Preferably, a sealing strip is provided at the top opening of the box body, and the sealing strip is in the form of a closed loop.

[0007] Preferably, bearings are provided in the inner walls of both sides of the box, and the two ends of the same rotating shaft are fitted into two bearings in the same axial direction.

[0008] Preferably, the inner wall of the box is provided with a plurality of oil seals, each of which is sleeved on the end of the rotating shaft.

[0012] The beneficial effects of this utility model are:

[0013] In this invention, a motor drives a transmission linkage to perform circular motion. Through the rotational connection of the driven linkage, the long linkage drives the short linkage to rotate, thereby achieving the rotation effect of the rotating shaft. This enables the adjustment of the angle of the doctor blade and doctor plate on each rotating shaft, allowing the doctor blade to perform the doctor blade operation on the ink cartridge printhead. Furthermore, by setting multiple doctor blades and distributing them in different positions, each printhead can achieve an individual doctor blade effect, improving doctor blade efficiency. After the doctor blade finishes doctoring, the printhead module descends into the cartridge, and the seal between the cartridge and the printhead module can be used to keep the printhead module moisturized.

[0014] In this invention, the cooperation between the pin, spring plate, spring and handle ensures the installation stability of the doctor blade on the doctor blade holder, while making the installation and removal of the doctor blade on the doctor blade holder more convenient and facilitating the cleaning of the doctor blade later.

[0024] Specifically, in this embodiment, bearings 15 are provided in the inner walls of both sides of the box 1 along the longitudinal direction, and the two ends of the same rotating shaft 6 are fitted into two bearings 15 in the same axial direction to ensure that the rotating shaft 6 rotates smoothly.

[0025] Specifically, in this embodiment, a number of oil seals 16 are provided on the inner wall of the box body 1. Each oil seal 16 is sleeved on the end of the rotating shaft 6 to improve the internal sealing of the box body 1 and ensure the moisturizing effect.

[0026] Specifically, in this embodiment, the pin 8 has a rectangular cross-section, and the top edge of the side near the scraper plate 9 is beveled to prevent the scraper plate 9 from shaking after installation, while also making the scraper plate 9 easier to operate during the pressing and installation process.

[0027] Specifically, in this embodiment, a sleeve 17 is provided on the outer wall of the ink scraper 7, and the spring 11 and spring plate 10 are both arranged inside the sleeve 17 to provide protection for the spring 11 and prevent corrosion.

[0028] Specifically, in this embodiment, the outer diameter of one end of the handle 12 connected to the spring plate 10 is smaller than the inner diameter of the sleeve 17 and is arranged inside the sleeve 17, while the outer diameter of the other end is larger than the outer diameter of the sleeve 17 and is arranged outside the sleeve 17, which helps to pull the handle 12.

[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
