Abstract

An inkjet printing device comprises a maintenance module, an inkjet unit, a pump, a sliding block and a rocker gear; wherein, the rocker gear is connected with a motor of the pump and can be coupled with the sliding block in a separable way; when the motor rotates in the first direction to drive the rocker gear to rotate to a first angle and to be meshed with the sliding block, the sliding block is further driven to move from a initial position to a first position and simultaneously a valve tappet on the maintenance module is used for turning on a valve of the inkjet unit. When the motor rotates in a second direction and drives the rocker gear to rotate to a second angle to be meshed with the sliding block, the sliding block is further driven to be separated from the first position so as to turn off the valve.

Description

Inkjet-printing device

Technical field

The present invention relates to a kind of printing equipment, particularly relate to a kind of inkjet-printing device.

Background technology

The ink cartridge of general ink-jet printer normally is combined as a whole ink cartridge and ink gun, owing to the ink cartridge of this kind form can't be reused after ink gun fault or ink use up again, so cost of manufacture is higher and cause waste easily.In addition, ink cartridge is separated with ink gun, when the ink in ink gun fault or the ink cartridge uses up, only need indivedual ink gun or ink cartridges changed.Because the ink cartridge/ink cartridge in the ink-jet printer still must often change, therefore how going out a kind of dynamical ink supply system beginning in the ink-jet printer indoor design becomes an important topic.

The specific embodiment

At first see also Fig. 1, inkjet-printing device in the present embodiment comprises safeguards module 10, a pump 20, an ink jet unit 30, a rocker gear 40 and a slide block 50, the motor that above-mentioned rocker gear 40 connects in the pump 20, maintenance module 10 comprises a bearing part 11 and a pedestal 12, and wherein bearing part 11 can slide on pedestal 12.Aforementioned ink jet unit 30 inside have an ink accumulator tank (not shown), its ink inside accumulator tank (ink reservoir) has four compartments, in order to holding green grass or young crops, red, yellow, black four chromatic inks respectively, and can be connected with an ink cartridge (not shown) by the

conduit

31,32,33,34 of four correspondences.In addition, then have an ink gun (not shown) in ink jet unit 30 bottoms, connect above-mentioned ink accumulator tank, ink jet unit 30 can break away from maintenance module 10 during printing, and by ink gun ink is sprayed onto (a for example paper) on the recording medium; In the process of printing when if any ink (blue or green, red, yellow, black) needs are additional, ink jet unit 30 can move to maintenance module 10 tops and combine (as shown in Figure 1) with bearing part 11, is beneficial to carry out the action of ink filling (priming).

As shown in Figure 1, be provided with four valves 31 ', 32 ', 33 ', 34 ' in ink jet unit 30 bottoms, the tappet P1～P4 by four activities on the maintenance module 10 can control aforementioned valve 31 '～34 ' respectively.When valve 31 ', 32 ', 33 ', 34 ' is opened, pump 20 can be by passage 35 places of bearing part 11 bottoms bleed (shown in arrow A 1), and in ink jet unit 1, form negative pressure, be used for respectively the green grass or young crops of ink cartridge, red, yellow, black four chromatic inks being imported in the ink accumulator tank.In the present embodiment, aforementioned tappet P1～P4 is arranged on the bearing part 11 and four valves 31 ', 32 ', 33 ', 34 ' of connecting ink jet unit 30 bottoms when opening versatilely, and pump 20 can be by passage 35 places of bearing part 11 bottoms bleed (shown in arrow A 1).

Please continue to consult Fig. 1, before the action of carrying out the ink filling; rocker gear 40 is positioned at one first angle; 50 of slide blocks are positioned at an initial position and do not contact with tappet P1～P4, this moment valve 31 ', 32 ', 33 ', 34 ' because of be in closed condition can't ink importing ink accumulator tank with ink cartridge in.Then please join quarrel Fig. 2, when desire imports the ink accumulator tank with the particular ink in the ink cartridge, motor in the pump 20 at first is that (first direction) rotation along clockwise direction rotates to one second angle to drive rocker gear 40 by aforementioned first angle, and makes a driven gear 41 of rocker gear 40 ends and the tooth-strip part 53 on the slide block 50 mesh.

In particular, rotate in the process of second angle by first angle at rocker gear 40, bearing part 11 on the maintenance module 10 moves to coordinate Z2 (as Fig. 3 B shown in) by coordinate Z1 (as shown in Figure 3A) along Z-direction with respect to pedestal 12 simultaneously, and bearing part 11 was positioned at a filling position and made the stop section S that protrude on bearing part 11 right sides be positioned on the Plane of rotation of rocker gear 40 this moment.Next, along with the motor in the pump 20 is to continue to be rotated in a clockwise direction, driven gear 41 can drive slide block 50 and move to a primary importance (as shown in Figure 4) towards left, and 51 of first projections on the slide block 50 can upwards push against tappet P1 and Open valve 31 ' at this moment.

Please join quarrel Fig. 5, after valve 31 ' was unlocked, the motor in the pump 20 is (second direction) rotation in the counterclockwise direction then, was used for ink jet unit 30 is implemented the ink filling.In particular, though this moment, rocker gear 40 can be driven by motor and rotation in the counterclockwise direction, yet because the abutting part 42 on the rocker gear 40 can stop by stop section S, be unlikely so rocker gear 40 can stop at a third angle degree (as shown in Figure 5) with slide block 50 on tooth-strip part 53 mesh; That is slide block 50 can rocker gear 40 drive and was still in primary importance this moment, made valve 31 ' to be held open, and was beneficial to continue to carry out the ink filling.

After the ink filling was finished, bearing part 11 was to return back to coordinate Z1 (state shown in 3A figure) along Z-direction, and made stop section S break away from the Plane of rotation of rocker gear 40; Next, 40 of rocker gears can rotate in the counterclockwise direction along with the motor of pump 20 and return back to first angle, so with slide block 50 on tooth-strip part 53 engagements (as shown in Figure 6).At last, driven gear 41 drives by rocker gear 40 ends make slide block 50 return back to the initial position shown in the 1st figure.In particular, when slide block 50 was returned to initial position, driven gear 41 broke away from tooth-strip part 53 terminal disengagings with it because of marching to, so can make slide block 50 be still in initial position.

In the present embodiment, aforementioned slide block 50 can be by the drive of rocker gear 40 along the X-direction translation, wherein, can open different valve 31 ', 32 ', 33 ', 34 ' respectively, be used for optionally implementing the filling of monochrome (blue or green, red, yellow, black) ink along with the difference of shift position.Yet, also can utilize rocker gear 40 to drive slide block 50 and move to a second place, make second projection 52 on the slide block 50 upwards push against tappet P1～P4 simultaneously, be used for Open valve 31 '～34 ' (as shown in Figure 7) simultaneously, and then can implement the filling of four looks (blue or green, red, yellow, black) ink simultaneously.

Though disclosed the present invention in conjunction with above preferred embodiment; yet it is not in order to limiting the present invention, anyly is familiar with this operator, without departing from the spirit and scope of the present invention; can do some change and retouching, so protection scope of the present invention should be with being as the criterion that claim was defined.
