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 the module support contiguous block 5 of fixedly connected shower nozzle module 6, wherein, drive motors 3 is fixed on the support 1, driving ball-screw 43 by shaft coupling 41 rotates, the end that ball-screw 43 is connected with shaft coupling 41 can thrust bearing 42 of socket, is used for carrying the weight of module support contiguous block 5, shower nozzle module 6 and ball-screw 43 self.The other end of ball-screw 43 can one of socket be fixed on the deep groove ball bearing 44 on the support 1, is used for preventing that ball-screw 43 is in the swing of rotation process.Ball-screw 43 can drive module support contiguous block 5 and move along line slideway 2 when rotating.Line slideway 2 is generally one, in order to make module support contiguous block 5 held stationary in sliding process, two or more line slideway that is parallel to each other 2 can also be set.In addition, be to fixedly connected between shower nozzle module 6 and the module support contiguous block 5, the motion by module support contiguous block 5 can drive shower nozzle module 6 and move together.And module support contiguous block 5 is between line slide rail 2 and shower nozzle module 6, and the width of module support 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 directions.
In shower nozzle module apparatus for controlling of lifting, module support contiguous block 5 is arranged between line slideway 2 and the shower nozzle module 6, purpose is that line slideway 2, module support 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 wideest, and be perhaps wide with module support contiguous block 5.Mutual applying that just can be very close to each other between a plurality of shower nozzle modules 6 of therefore arranging side by side can not hindered by other structure and produces the interval.She Ji advantage is exactly like this, can be according to concrete spray printing needs, and the shower nozzle module 6 of the varying number of arranging side by side makes PRN device can deal with the more printing demand of wide region.
In the practical work process of equipment, shower nozzle module 6 need be adjusted height according to the thickness of different stocks, in the process that module support contiguous block 5 moves up and down, owing to can not allow the scratch surface of stock of shower nozzle module, 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 is positioned at a side of close line slide rail 2 belows.The effect of lower limit optoelectronic switch 12 is to detect module support contiguous block 5 whether to reach the limit of the position when moving downward.Lower limit optoelectronic switch 12 is to come opening and closing by light sensitivity principles, therefore needs to arrange a lower limit jackscrew 54 that cooperates with lower limit optoelectronic switch 12 at module support contiguous block 5.Lower limit jackscrew 54 is installed on the module support contiguous block 5, the structure of module support contiguous block 5 comprises two vertical frame plates and is connected between two vertical frame plates one and go up under frame plate 51 and two and set a roof beam in place 52, and ball-screw 43 is set a roof beam in place under the centre of last frame plate 51 and two and passed between 52; One of them vertical frame plate is connected with the shower nozzle module, and another vertical frame plate is connected on the line slideway 2 by connector 53.Module support contiguous block 5 is generally integrated overall structure, certainly, also can be the structure that each assembly splicing fixedly forms.According to the different different structures of needs configuration.Close connector 53 places at last frame plate 51 connect a lower limit jackscrew 54, the position probing that cooperates lower limit optoelectronic switch 12 to realize module support contiguous block 5.
When module support 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; control system stops module support contiguous block 5 at this point and continues descending; thereby make shower nozzle module 6 be unlikely to be attached on the stock, played the protective effect to shower nozzle module 6.
In addition, lower limit jackscrew 54 can also play the adjustable effect of extreme position that makes module support contiguous block 5 descending, lower limit jackscrew 54 can screw in or screw out module support contiguous block 5, corresponding lower limit optoelectronic switch 12, when lower limit jackscrew 54 screws in module support contiguous block 5, the descending extreme position of module support 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 concrete needs, thereby realizes the adjusting to each shower nozzle module 6 different descending extreme position.
In order to guarantee that further module support contiguous block 5 can be descending crosses the position, a mechanical stop limiter 11 that is fixed on the support 1 can also be set, be positioned at the side near line slide rail 2 belows.When module support contiguous block 5 went downwards to extreme position, mechanical stop limiter 11 can withstand module support contiguous block 5, and it is descending that it can not be continued 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 mechanical stop limiter 11 can only be set, according to different conditions and demand different equipment is installed.
Further, except the limit inferior position of module support contiguous block 5 when descending can arrange lower limit optoelectronic switch 12 and mechanical stop limiter 11, can also a upper limit optoelectronic switch 13 be set at module support contiguous block 5 up extreme positions, be fixed on upper limit optoelectronic switch 13 on the support 1 and be positioned at a side near line slide rail 2 tops.The effect of upper limit optoelectronic switch 13 is to send signal to system when detecting module support contiguous block 5 and being up to extreme position, and system's control module support contiguous block continues up, acts on equally with lower limit optoelectronic switch 12, does not repeat them here.Simultaneously, connect a upper limit jackscrew, the position probing that cooperates upper limit optoelectronic switch 13 to realize module support contiguous block 5 at set a roof beam in place 52 close connector 53 places of module support contiguous block 5 following.Function is identical with lower limit jackscrew 54, does not repeat them here.
The present invention also provides a kind of printing equipment of using 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 to lack is made up of two shower nozzle module apparatus for controlling of lifting, width among each row between the spray printing zone 61 of adjacent two shower nozzle module 6 bottoms equals the width in the spray printing zone 61 of shower nozzle module 6 bottoms, the positions of the two row's shower nozzle module apparatus for controlling of lifting width in spray printing zone 61 of shower nozzle module 6 bottoms that staggers mutually.
The concrete set-up mode of spray printing equipment is, needing to install two row's shower nozzle module apparatus for controlling of lifting in the spray printing equipment just can make the image of print area uninterrupted, therefore, need certain position of staggering mutually between two row's shower nozzle modules 6 of arranging side by side, the non-spray printing zone 62 of each row's shower nozzle module 6 is filled up by the spray printing zone 61 of another row's shower nozzle module 6, therefore the distance that staggers mutually of two row's shower nozzle module apparatus for controlling of lifting is exactly the width in the spray printing zone 61 of shower nozzle module 6 bottoms, just can realize the effect of seamless printing in the spray printing process.
