Embodiment Construction

[0012] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further elaborated below in conjunction with illustrations and specific embodiments.

[0013] The nozzle striker structure of the large character inkjet printer proposed by the present invention is as follows: figure 1 , figure 2 As shown, the head of the striker 32 is located in the cavity between the upper ink tank 1 and the lower ink tank 2, the tail of the striker 32 extends into the inductance coil 31 and is connected with the moving iron core, the inductance coil 31 drives the striker 32 to move, There is a group of nozzle holes 11 in the ink tank 1, and the ink 6 can be accommodated in the cavity. The movement of the striker 32 makes the ink 6 eject from the nozzle holes 11. The striker 32 includes a needle bar 321, and the head of the needle bar 321 A bumper 322 is provided. The bumper 322 is molded by ...

Abstract

The invention provides an impact needle of a spray head of a large character code spraying machine. The head of the impact needle is positioned in a cavity between an upper ink fountain and a lower ink fountain; the tail of the impact needle stretches into an inductance coil and is connected with a movable core; the inductance coil drives the impact needle to move; a group of spray holes are formed in the upper ink fountain; ink can be accommodated in the cavity; and the impact needle moves to ensure that the ink is sprayed from the spray holes. The impact needle comprises a needle rod, wherein an impact block is arranged on the head of the needle rod and manufactured by forming a polytetrafluoroethylene material; a spring is arranged on the needle rod; the fixed end of the spring is connected to the needle rod; and the movable end of the spring is connected with the impact block. The impact block at the tail end of the impact needle is manufactured by forming polytetrafluoroethylene with an extremely low friction coefficient, and high mechanical property can be kept in a wide temperature range, so that the code spraying machine normally works in various environments, the maintenance cost of equipment can be reduced, and the service life is prolonged.

Description

technical field [0001] The invention relates to a large-character inkjet printer, in particular to a striker used in the nozzle of the large-character inkjet printer. Background technique [0002] Before printing products using inkjet printers, most manufacturers used stamps and stickers to distinguish the production time, batch number, etc. Moreover, stamping, pad printing or roller printing requires a typeface for each letter or number. The intuitive effect is poor, the ink distribution is uneven, and it is not timely. The operation is cumbersome and requires manual online processing, so the work efficiency is low. . The inkjet printer equipment enters the printing information through the manual keyboard, and through the ink supply system, it automatically detects the passing of the object to realize the automatic printing of ink. There are 7 high-performance solenoid valves in the nozzle, and the height of the printing font is 20mm, and each font is composed of 7×5 dot ...
