The two ends of described guide rail 1 are provided with the striker 6 for answering back to slide block 3.7.
Described band-like film 4 is transparent membrane.
As shown in Figure 1, during utility model works, first laterally being clipped in by band-like film 4 is equipped with between the slip resin storage tank 2 of liquid printed material and film pressing device 3, end, two ends and the end, slip resin storage tank 2 two ends of film pressing device 3 are fastened, and are then fixed at band-like film 4 two ends on the stretch-draw spool 5 being positioned at guide rail 1 two; Stretch-draw spool 5 is regulated to make band-like film 4 be in tight horizontal operation state; Because the lower surface of band-like film 4 contacts with the 3rd roller bearing 2.3 with the first roller bearing 2.1, elastic scraper 2.2, upper surface contacts with two second roller bearings 3.9 with left scraper plate 3.1, right scraper plate 3.2; Therefore slip resin storage tank 2 can horizontally slip along band-like film 4 together with film pressing device 3.
When on the right side of slip resin storage tank 2 slides to guide rail 1; The right striker 6 can collide with slide block 3.7 and be moved to left by slide block 3.7, the nose bar of pull bar 3.6 upper end is in bottom gradient hole 3.8, the lifter plate 3.4 be connected with pull bar 3.6 lower end is in the state do not raised, therefore the elasticity push jack 3.5 of lifter plate 3.4 two ends sidewall does not contact with band-like film 4, elastic scraper 2.2, left scraper plate 3.1, right scraper plate 3.2 all with band-like film 4 close contact, thus band-like film 4 upper and lower surface can not take liquid printed material out of.
When on the left of slip resin storage tank 2 slides to guide rail 1; Left side striker 6 can collide with slide block 3.7 and be moved to right by slide block 3.7, the nose bar of pull bar 3.6 upper end is in top, gradient hole 3.8, the lifter plate 3.4 be connected with pull bar 3.6 lower end rises and raises, thus drive the elasticity push jack 3.5 of lifter plate 3.4 two ends sidewall to rise between embedding band-like film 4 and left scraper plate 3.1, thus make to occur gap between left scraper plate 3.1 and band-like film 4 upper surface; When slip resin storage tank 2 moves to right along guide rail 1, band-like film 4 upper surface can take a layer thickness printed material identical with described gap thickness out of from slip resin storage tank 2; Now the print platform controlled in the middle of guide rail 1 drops to lower surface and contacts with band-like film 4 and printed material by being positioned at laser below band-like film 4 or ultraviolet light polymerization band-like film 4 upper surface; The print job of one deck can be completed; Because elastic scraper 2.2, right scraper plate 3.2 all keep close contact with band-like film 4, thus band-like film 4 lower surface and band-like film 4 upper surface be positioned on the right side of right scraper plate 3.2 can not take liquid printed material out of.After having printed one deck due to slip resin storage tank 2 slide on the right side of guide rail 1 time, the right striker 6 can again collide with slide block 3.7 and be moved to left by slide block 3.7, elasticity push jack 3.5 is made to depart from the contact with band-like film 4, recover band-like film 4 and left scraper plate 3.1 close contact and the gap of eliminating between them, therefore when the resin storage tank 2 that slides after having printed one deck moves to left along guide rail 1, left scraper plate 3.1 can scrape the unnecessary printed material of band-like film 4 upper surface and be recycled in slip resin storage tank 2 by the printed material recovery holes on left scraper plate 3.1, repeat the periodic cycle that said process can realize feed-printing-reclaimed materials.
