Description

Impact Silencer for Inkjet Printers with Flat Inks

The present invention relates to an impact noise preventing device of an ink jet printer, and more particularly, to an impact noise device of an ink jet printer using a flat ink for reducing impact noise generated when driving a home position using a flat ink.

Commonly used inkjet printers heat the ink stored in the head to increase the pressure in the ink cartridge and generate bubbles like soap bubbles. The bubbles generated in this way are sprayed through the nozzles to form letters and attached to the printing paper to print.

The printing method shows a font or a picture on a printing paper, and is also called an ink bubble jet method in the sense of using bubbles.

The number of nozzles used in such an inkjet printer is generally about tens (56 to 108). In addition, the font type can be downloaded by a program (Down Load), it is also possible to print a picture or a picture. The resolution of fonts and pictures of such an inkjet printer is generally about 300 to 1200 DPI (Dot Per Inch), and color printing is also possible depending on the type of head to be installed.

The printing process of a general inkjet printer is composed of a paper feeder unit for feeding paper, and a transfer device unit for transporting the paper fed from the paper feeder unit for printing.

In addition, the paper conveyed from the conveying device unit is a series of processes through a printing device unit for printing through a head with a nozzle for ejecting ink, and a discharge device unit for discharging the paper printed by the printing device unit It consists of a terminating structure.

Since inkjet printers print by ejecting ink through nozzles mounted on the heads, the nozzles of the heads are cleaned, and nozzles attached to the heads when the power is turned off during standby or without printing. The ink must always be sealed before and after printing to prevent the ink from drying out.

A device that performs this function is called a home position device. The home position device is configured according to the characteristics of each head for each company that produces the printer. The method of driving the home position device is to use an independent motor and a carrier. There is a method using sliding.

Here, the method using the sliding method of the carrier, as shown in Figs. 1 and 2, in order to wipe the nozzle 23 surface of the head 22, the wiper is started after wiping the lever wiper 43 is locked After the 33 wipes the surface of the nozzle 23 attached to the head 22 and the right rib of the carriage 20 touches the lever wiper 43, the lever wiper 43 rotates counterclockwise while the locking device It is released.

At this time, the tension force of the resilient member and the force that the head 22 presses the wiper 23 act at the same time, so that the cap assembly 30 is instantaneously lowered along the guide rail 41 installed in the groove frame 30. Will fall.

That is, the cap assembly 30 has a problem that the noise is generated by a large impact due to the force falling along the guide rail 41.

In addition, the method using a rotation of the gear by driving a separate motor has a problem that the impact noise is reduced but the noise generated by the driving of the motor, the cost is up (Up) due to the increase in the material cost.

The present invention aims to minimize the impact noise generated when the cap assembly is driven by using a flat-ink for absorbing ink generated during wiping and stepping.

In order to achieve the above object, the flat-ink which is laid on the bottom of the apparatus set is installed inside the groove frame 40 composed of the hinger 42, the lever wiper 43, which is a locking device, and the guide rail 41. There is one characteristic.

1 and 2 illustrate the operation of the home position unit according to the prior art.

State diagram,

3 is a perspective view showing an internal configuration of an inkjet printer according to the present invention,

4 is a block diagram of the component shown in FIG. 3.

The construction and operation of the present invention will be described in detail with reference to the accompanying drawings.

Figure 3 shows a perspective view according to the embodiment of the present invention, the head 22 is equipped with a nozzle 23 for ejecting the ink is mounted and moved left and right along the guide shaft 11 by the printing command A cap assembly provided with a carriage unit 20 for spraying the wiper, a wiper 33 for wiping, a cap 32 for capping, and a stopper 34 for locking the lever wiper 43; 30, an assembly hinger 42, which is a means for mounting the cap assembly 30 to the groove frame 40, a lever wiper 43, which is a locking device, a guide rail 41, and the cap. The assembly portion 30 is composed of a home frame 40 portion composed of a flat-ink 44 for absorbing a shock during driving and reducing noise, and a main frame 10 constituting the apparatus.

That is, the configuration of the home position device unit according to the present invention is composed of the components shown in FIG.

Looking at the operation of the home position portion according to this configuration in detail, in general, the power supply is turned off in the power off state, the carriage 21 in the home position portion to wipe the nozzle 23 surface of the head 22 during printing Move to the print section.

That is, when the carriage 21 equipped with the head 22 moves to the printing section for printing, the carriage 21 collides with the protrusion 34 formed in the cap assembly 30 after the carriage 21 is grooved. It is out of the position part.

In this case, the cap assembly unit 30 is moved while the hinge assembly 42 of the cap assembly unit moves along the guide rail 41 of the groove frame unit 40.

At this time, a flat plate attached to the bottom surface of the cap assembly 30 and the groove frame 40 before the hinger 42 and the groove frame 40 of the cap assembly 30 collide with the ends of the guide rails 41. Impact noise is minimized as the top surface of the ink 44 strikes.

As described above, by attaching the flat ink mounted in the device set into the home position device, the noise generated when the plastic and the plastic collide with the plastic paper and the soft paper collides to minimize the noise generated during the impact. It is effective to maximize the satisfaction of the device.
