Problems solved by technology
[0008] 1. High requirements on the secondary injection molding process: Since the thickness of the rubber body part of the secondary injection molding is very small (about 0.5mm), this requires that the fluidity of the rubber after melting is very high, which limits the choice of raw materials for the rubber body;
[0009] 2. The precision of the mold needs to be very high during secondary injection molding
It is very difficult to assemble the mold and control the parameters of the injection molding machine (injection temperature, pressure, etc.) during the secondary injection molding process, which makes the production cost of the ink stack relatively high;
[0010] 3. If this secondary injection molding process is used to design a smaller-sized ink stack to match the sealing of small-sized nozzles, it will increase the difficulty of processing and production.
On the contrary, if a large-sized ink stack is designed, the amount of deformation after the second injection will become more difficult to control, and it is likely to exceed the allowable deviation

The invention discloses an inkstack structure of a novel inkjet printer which aims at solving the deficiencies of high requirement of plastic injection technique, short service life of the inkstack, etc. of the inkstack structure of the existing inkjet printer and comprises a sponge body, a netting, a plastic supporting body and a rubber body; wherein, the rubber body is fixed on the plastic supporting body in the manner of non-plastic injection. The invention has the advantages of breaking through the binding of the existing processing manufacturing technique and the limitation of the material use; reducing the difficulty and the cost of the process production; adopting the loose fit among the components, and improving the utilization efficiency and the service life of the product.
Description
technical field [0001] The invention relates to an ink stack structure on a nozzle cleaning assembly of an inkjet printer. Background technique [0002] At present, a main method of known cleaning, maintenance and maintenance of inkjet printer nozzles is to use cleaning components. Its working principle is: before the inkjet printer starts to work and during the working process, when the nozzle hole on the nozzle is blocked, the cleaning component starts to work, and the mechanism movement on the cleaning component seals the ink stack and the nozzle to form a cavity body, the external pump body starts to suck ink, so that the cavity forms a negative pressure, and the ink in the nozzle hole is sucked out, thus dredging the flow channel in the nozzle hole on the nozzle. When the inkjet printer is finished, if it does not work for a long time, in order to keep the nozzle moist, to prevent the ink from drying up, to isolate the dust in the outside air, so that the nozzle hole i...
