As shown in Figure 2, the shower nozzle module apparatus for controlling of lifting that the present invention proposes, comprise drive motors 3, shaft coupling 41, ball-screw 43, support 1 and line slideway 2, and be fixedly connected with the module bracket contiguous block 5 of shower nozzle module 6, wherein, drive motors 3 is fixed on support 1, ball-screw 43 is driven to rotate by shaft coupling 41, one end that ball-screw 43 is connected with shaft coupling 41 can be socketed a thrust bearing 42, is used for carrying the weight of module bracket contiguous block 5, shower nozzle module 6 and ball-screw 43 self.The other end of ball-screw 43 can be socketed a deep groove ball bearing 44 be fixed on support 1, for preventing the swing of ball-screw 43 in rotation process.Ball-screw 43 can drive module bracket contiguous block 5 to move along line slideway 2 when rotating.Line slideway 2 is generally one, in order to make module bracket contiguous block 5 held stationary in sliding process, can also arrange the line slideway 2 that two or more is parallel to each other.In addition, be fixedly connected with between shower nozzle module 6 with module bracket contiguous block 5, shower nozzle module 6 can be driven to move together by the motion of module bracket contiguous block 5.And module bracket contiguous block 5 is between line slideway 2 and shower nozzle module 6, and the width of module bracket contiguous block 5 on the arragement direction of several shower nozzle module apparatus for controlling of lifting arranged side by side is less than or equal to the width of shower nozzle module 6 on several shower nozzle module apparatus for controlling of lifting arragement direction.
In shower nozzle module apparatus for controlling of lifting, be arranged on by module bracket contiguous block 5 between line slideway 2 and shower nozzle module 6, object is that line slideway 2, module bracket contiguous block 5 and shower nozzle module 6 are arranged in a linear, and shower nozzle module 6 is positioned at outermost.The width of shower nozzle module 6 on the arragement direction of several shower nozzle module apparatus for controlling of lifting is the widest, or wide with module bracket contiguous block 5.Just can be very close to each other between multiple shower nozzle modules 6 of therefore laid out in parallel bonded to each other, can not be hindered by other structure and produce interval.The advantage of such design is exactly, can according to concrete spray printing needs, and the shower nozzle module 6 of laid out in parallel varying number makes printing device can deal with the printing demand of more wide region.
In the practical work process of equipment, shower nozzle module 6 needs the thickness according to different stock and adjusts height, in the process that module bracket contiguous block 5 moves up and down, to scratch the surface of stock due to shower nozzle module can not be allowed, therefore in shower nozzle module apparatus for controlling of lifting, also need to arrange lower limit optoelectronic switch 12, lower limit optoelectronic switch 12 is fixed on the support 1 and side be positioned at below line slideway 2.The effect of lower limit optoelectronic switch 12 detects module bracket contiguous block 5 whether to reach the limit of position when moving downward.Lower limit optoelectronic switch 12 opens and closes by light sensitivity principles, on module bracket contiguous block 5, therefore need the lower limit jackscrew 54 arranging and lower limit optoelectronic switch 12 cooperation.Lower limit jackscrew 54 is arranged on module bracket contiguous block 5, the structure of module bracket contiguous block 5 sets a roof beam in place 52 under comprising two vertical frame plates and being connected between two vertical frame plates one upper frame plate 51 and two, and ball-screw 43 is set a roof beam in place between 52 and passed under the centre of upper frame plate 51 and two; One of them vertical frame plate is connected with shower nozzle module, and another vertical frame plate is connected on line slideway 2 by connector 53.Module bracket contiguous block 5 is generally integrated overall structure, certainly, also can be each assembly splicing structure fixedly.According to the different structures needing configuration different.Connect a lower limit jackscrew 54 at close connector 53 place of upper frame plate 51, coordinate lower limit optoelectronic switch 12 to realize detecting the position of module bracket contiguous block 5.
When module bracket contiguous block 5 goes downwards to certain position; lower limit jackscrew 54 has stopped the light path of lower limit optoelectronic switch 12; lower limit optoelectronic switch 12 can send signal to control system; it is descending that control system stops module bracket contiguous block 5 to continue at this point; thus make shower nozzle module 6 be unlikely to be attached on stock, serve the protective effect to shower nozzle module 6.
In addition, lower limit jackscrew 54 can also play the adjustable effect of the extreme position that makes module bracket contiguous block 5 descending, lower limit jackscrew 54 can screw in or screw out module bracket contiguous block 5, corresponding lower limit optoelectronic switch 12, instantly when spacing jackscrew 54 screws in module bracket contiguous block 5, the descending extreme position of module bracket contiguous block 5 will change, therefore shower nozzle module apparatus for controlling of lifting just can arrange the position of lower limit jackscrew 54 according to specific needs, thus realizes the adjustment to the different descending extreme position of each shower nozzle module 6.
In order to guarantee that module bracket contiguous block 5 descendingly can not cross position further, a mechanical stop limiter 11 be fixed on support 1 can also be set, be positioned at the side below line slideway 2.When module bracket contiguous block 5 goes downwards to extreme position, mechanical stop limiter 11 can withstand module bracket contiguous block 5, makes it not continue descending again, can play the protective effect to shower nozzle module 6 equally.On support 1, mechanical stop limiter 11 and lower limit optoelectronic switch 12 can be set simultaneously, also can mechanical stop limiter 11 be only set, according to different conditions and demand, different equipment be installed.
Further, except the lower limit position of module bracket contiguous block 5 when descending can arrange lower limit optoelectronic switch 12 and mechanical stop limiter 11, a upper limit optoelectronic switch 13 can also be set at the extreme position that module bracket contiguous block 5 is up, upper limit optoelectronic switch 13 be fixed on the support 1 and side be positioned at above line slideway 2.The effect of upper limit optoelectronic switch 13 detects when module bracket contiguous block 5 is up to extreme position to send signal to system, and Systematical control module bracket contiguous block continues up, acts on the same with lower limit optoelectronic switch 12, does not repeat them here.Meanwhile, module bracket contiguous block set a roof beam in place for 5 times 52 close connector 53 place connect a upper limit jackscrew, coordinate upper limit optoelectronic switch 13 to realize detecting the position of module bracket contiguous block 5.Function is identical with lower limit jackscrew 54, does not repeat them here.
The present invention also provides a kind of printing equipment applying shower nozzle module apparatus for controlling of lifting in above-described embodiment, as shown in Figure 3, this printing equipment can comprise two row's shower nozzle module apparatus for controlling of lifting, each drains into and is made up of two shower nozzle module apparatus for controlling of lifting less, width between spray printing region 61 in each row bottom adjacent two shower nozzle modules 6 equals the width in the spray printing region 61 bottom a shower nozzle module 6, staggers the width in the spray printing region 61 bottom a shower nozzle module 6 mutually in the positions of two row's shower nozzle module apparatus for controlling of lifting.
The concrete set-up mode of spray printing device is, needing installation two to arrange shower nozzle module apparatus for controlling of lifting in spray printing device just can make the image of print area uninterrupted, therefore, certain position of mutually staggering is needed between two row's shower nozzle modules 6 of laid out in parallel, the non-spray printing region 62 of each row's shower nozzle module 6 is filled up by the spray printing region 61 of another row's shower nozzle module 6, therefore the distance that two row's shower nozzle module apparatus for controlling of lifting stagger mutually is exactly the width in the spray printing region 61 bottom a shower nozzle module 6, just can realize the effect of seamless printing in jet printing process.
