The specific embodiment
Please refer to Fig. 5, Fig. 5 can vertically clean the schematic diagram of the maintenance mechanism of ink-jet head 10 of ink gun brush sheet for the present invention.Maintenance mechanism of ink-jet head 10 comprises housing 20, first platform 30, second platform 40.Its middle shell 20 is provided with first chute 22 and second chute 24, in the present embodiment, first chute 22 is inclined ladder shape, second chute 24 is horizontal in-line, yet the shape of first chute 22 and second chute 24 is not limited to the structure of present embodiment, the chute of Any shape as long as win platform 30 and second platform 40 can be done and the disclosed identical relative motion of present embodiment, all can be used as the embodiment of first chute 22 and second chute 24.In addition, maintenance mechanism of ink-jet head 10 comprises leverage 60 in addition, being installed on first platform 30 along the mode of axle center rotation.Leverage 60 has trip 66 and flange 64, and trip 66 can interact with the catching groove 26 on the housing 20, and in addition, flexible assembly 28 is connected between housing 20 and the leverage 60 in addition, and elastic parts 28 can be spring.The present invention reaches the purpose that scaler strikes off residual ink on the ink gun brush sheet by the relative motion between first platform 30 and second platform 40.
Please refer to Fig. 6 and Fig. 7.Fig. 6 is the schematic diagram of first platform 30, and Fig. 7 is the schematic diagram of second platform 40.Because in the maintenance mechanism of ink-jet head 10 of the present invention, the top that first platform 30 is arranged on second platform 40 (also can be arranged at the below, only need do corresponding slotted eye design in the below), therefore be close to ink gun brush sheet 35 and be provided with slotted eye 36, be used to provide the space that below second platform, 40 upright scalers 45 extend first platform 30, when scaler 45 extends slotted eye 36, scaler 45 just can be close to ink gun brush sheet 35, when first platform 30 and 40 on second platform have when moving both vertically relatively, scaler 45 on second platform 40 also has relative motion to ink gun brush sheet 35, to strike off the residual China ink on the ink gun brush sheet 35.
Please refer to Fig. 8 to Figure 12 and Figure 15, it is the continuous action schematic diagram of ink gun brush sheet 35 cleaning ink guns 55 in the maintenance mechanism of ink-jet head 10 of the present invention and scaler 45 cleaning ink gun brush sheets 35, Figure 15 is the schematic diagram of three sections 221,222,223 in first groove 22, wherein near ink gun 55, and the 3rd section 223 is between first section 221 and second section 222 than first section 221 for second section 222.In Fig. 8, when print cartridge 50 (having ink gun 55 on it) when not entering maintenance mechanism of ink-jet head 10 as yet, first platform 30 and second platform 40 are in " first state " in the maintenance mechanism of ink-jet head 10, and wherein first sliding pin 32 of first platform 30 is positioned at the bottom (first section 221) of inclined ladder shape first chute 22.In other words, first platform 30 is in extreme lower position.In this first state, scaler 45 ends on second platform 40 exceed its next-door neighbour's ink gun brush sheet 35, and act on ink gun brush sheet 35, so ink gun brush sheet 35 can be pushed and slight deformation by scaler 45.
In Fig. 9, after print cartridge 50 enters maintenance mechanism of ink-jet head 10 to the right, can promote on first platform 30 jag 38 and then drive first platform 30 to move to right-hand, because first sliding pin 32 of first platform 30 is subject to the shape of first chute 22, therefore first platform 30 can have moving of level (to the right) and vertical (making progress) direction simultaneously, and first sliding pin 32 can be positioned at the top (i.e. second section 222) of first chute 22 at last, in other words, first platform 30 is in the extreme higher position.In this simultaneously, because the scaler 45 on second platform 40 extends the slotted eye 36 on first platform 30, when first platform 30 is promoted by print cartridge 50, second platform 40 that first platform, 30 related drive scalers 45 of meeting and scaler 45 are fixed moves, second chute, 24 horizontal shapes limit on the housing 20 owing to second sliding pin 44 on second platform 40 is subjected to, and therefore second platform 40 is moved horizontally to the right by 30 drives of first platform only together.And moving of first platform, 30 vertical direction can not influence second platform 40.Therefore first platform 30 can be considered the relative motion with vertical direction, and does not have the relative motion of horizontal direction with respect to second platform 40.For brush sheet 35 of the ink gun on two platforms and scaler 45, then being equivalent to ink gun brush sheet 35 moves up with respect to scaler 45 so that is higher than scaler 45, this moment, scaler 45 no longer worked to ink gun brush sheet 35, this is " second state " of first platform 30 and second platform 40, shown in the 9th figure.When second state, be installed on leverage 60 on first platform 30 also along with first platform 30 moves, and the elastic parts 28 that is connected in 20 of leverage 60 and housings is elongated simultaneously, and the elastic parts 28 of elongation can cause leverage 60 relative first platforms 30 to produce fine rotation and the trip 66 on the leverage 60 is upwards promoted.
