Describe the utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
An embodiment of the present utility model provides a kind of device for ink of scraping, it is installed in the clean and maintenance device of ink-jet printing apparatus, be used to strike off the ink on the nozzle of ink-jet printing apparatus, comprise: scraper, tool rest and knife rest, wherein, scraper is to fixedly connected with tool rest, and tool rest and knife rest are to removably connect.
In the prior art, scraper directly is fixedly mounted on the knife rest by tens screws, so remove pretty troublesome.And in the present embodiment, increased tool rest, dismounting between tool rest and the knife rest is more convenient, scraper can be disassembled from knife rest together with tool rest and clean, this scraper that has solved in the existing ink-jet printing apparatus is not allowed easily detachable problem, greatly improve the dismounting convenience of scraper, shortened the manual maintenance time of blow head maintenance device.
Preferably, scraper is connected to tool rest by screw.
Fig. 3 shows the transverse cross sectional figure according to the scraper of the utility model preferred embodiment, and Fig. 4 shows the transverse cross sectional figure according to the doctor blade device of the utility model preferred embodiment.Scraper has two the orthogonal installed surface A faces and the B face of longitudinal extension, form right angle groove; Tool rest has the installed surface that matches with the installed surface of scraper, form right angle portion; The right angle portion of tool rest is embedded in the trough with straight angle of scraper, and is fixedly connected by screw.Among Fig. 3, A face B face is the mating surface of scraper, is used for fixing the datum level of scraper, and the right side is the blade insert that is used for the nozzle clearing face.
Fig. 5 shows the perspective cut away view according to the doctor blade device of the utility model preferred embodiment; Fig. 6 shows the front view of the doctor blade device of Fig. 5; Fig. 7 shows the cut away view of the AA line of Fig. 6; Fig. 8 shows the top view of the doctor blade device of Fig. 5; Fig. 9 shows the cut away view of the BB line of Fig. 8; Figure 10 shows the partial enlarged drawing of Fig. 9.Preferred embodiment among the figure adopts guide groove and double-wedge to compress combination, the operation that the mode of single-ended fixed doctor, this way have greatly been simplified dismounting and scraper is installed.Below by this group view, describe preferred embodiment of the present utility model in detail.
The right angle portion that the vertical installed surface A of scraper 6 faces down and extends beyond tool rest 7; Tool rest 7 also has two orthogonal installed surfaces of longitudinal extension, and the installed surface that extends beyond with scraper 6 constitutes first groove that Open Side Down; Knife rest 8 comprises first one of fixedly connected clean and maintenance device, and second one of going out from first longitudinal extension, and second one upper surface has second groove that the opening of longitudinal extension makes progress; A side of second groove closely is embedded in first groove.First two ends that can be positioned at knife rest is convenient to be installed on the clean and maintenance device, and second groove is positioned at the centre of knife rest.The space of first groove that the B face of scraper 6 and tool rest 7 forms must be a bit larger tham the width of the side (being flange) that second groove of knife rest 8 embeds, and can increase the convenience of installation in the B of scraper 6 face and tool rest 7 corresponding inboard chamferings.
Preferably, tool rest 7 is fixedly attached to knife rest 8 by screw, and the screw that is used for fixing connection tool rest 7 and knife rest 8 is less than and is used for fixing the screw that is connected scraper 6 and tool rest 7.Therefore by tool rest 7, can fixed doctor 6, can dismantle easily again.
Preferably, tool rest 7 is fixedly attached to by screw on the top of side of embedding first groove of knife rest 8.
Preferably, doctor blade device also comprises compact heap 9, first side of its knife rest 8 that is connected towards second groove, the side towards second groove of compact heap 9 constitutes downward chamfering, the end of tool rest 7 is a wedge shape, insert in the chamfering of compact heap 9, compact heap 9 is fixedly attached to the bottom of second groove by screw, small-sized elbow folder, fixed handle or Spring Card etc., and compresses the tapered end of tool rest 7.
Tool rest 7 terminal top edges are made smooth cambered surface, cooperate with knife rest 8 with the lower end mating surface, the chamfering of compact heap 9 is monolateral wedge shape, be pressed on the smooth cambered surface of tool rest 7 with lozenges during installation, when applying downward power for compact heap 9, by contacting of lozenges and smooth cambered surface, power is decomposed into the power of level and vertical direction, the power of horizontal direction guarantees that the combination of tool rest 7 and scraper 6 does not have displacement along the guide groove direction, the power of vertical direction with tool rest 7 by being pressed on the knife rest 8, thus, the relative knife rest 8 with the combination of tool rest 7 of scraper 6 is completely fixed.
Compact heap 9 is fixed on the knife rest 8, adopts downward lozenges to compress the arc surface of 7 liang of ends of tool rest, and the free degree of restriction tool rest on paper feed vertical direction (both direction) when the dismounting scraper, only needs the tool rest that the dismounting compact heap can will be equipped with scraper to pull down.Specifically, be provided with after the compact heap, scraper remove and install the operation as follows:
The disassembling section of scraper 6: when scraper 6 needs dismounting, only need unclamp the pressure of compact heap 9, take off compact heap 9, scraper 6 only needs to break away out a little along the guide groove on the knife rest 8 to one of compact heap 9 with the combination of tool rest 7, can upwards mention and lift down.
The fitting operation of scraper 6: when scraper 6 needs to install, with the sub-assembly of scraper 6 and tool rest 7 aim at guide groove to slip into away from a section of compact heap 9 top to the end after, put down this end of the outside, groove fully and the flange on the knife rest 8 combine, compact heap 9 is fixing, and scraper 6 promptly is completely fixed.
Preferably, tool rest 7 adopts the material with the ink compatibility, promptly adopts ink-repellant material.
Embodiment of the present utility model also provides a kind of ink-jet printing apparatus, and it comprises the clean and maintenance device, and the clean and maintenance device comprises the above-mentioned device for ink of scraping.
As can be seen from the above description, the utility model the above embodiments scrape the dismounting convenience that device for ink and ink-jet printing apparatus have greatly improved the cleaning attending device, shortened the manual maintenance time of blow head maintenance device.
The above is a preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
