Continuous printing production line of steel plate
Technical field
The invention belongs to printing technology, particularly a kind of continuous printing production line of steel plate, can realize printing and steel plate move continue carry out.
Background technology
At present, on steel plate printing production line, production Coil Coating Products is all to realize by roller coat, utilizes roller coat can realize continuous production.No matter be that several bakings of several paintings are all to complete, also on steel-plate continuous production line, do not implement the technology of plain net printing both at home and abroad under steel plate running status.Because must being static state, the traditional handicraft of plain net printing gets off to complete, but on steel-plate continuous production line, meet if the static print request of plain net typography, just need the equipment of whole production line in start-stop, the such non-steady state of start-stop, not only operating efficiency is very low, and it is complicated that its control system also can become.The invention solves the technical barrier that carries out plain net printing on steel-plate continuous production line, belong to pioneering both at home and abroad.
Summary of the invention
For problems of the prior art, the invention provides a kind of plain net printing and steel-plate continuous production line, can realize printing and steel plate move continue carry out.
Technical scheme of the present invention is achieved in that a kind of continuous printing production line of steel plate, comprise uncoiler, plate shearing machine, splicing machine, entry loop, plain net printing machine, outlet looping and winder, above-mentioned each equipment is arranged successively by the transport path of steel strip printing, steel band is supported by steel band roller, the steel band each equipment of pile warp successively that leads, be provided with tensioner at described outlet looping and entry loop two ends, between wherein said plain net printing machine and entry loop and outlet looping, be respectively provided with a material pit, steel plate between described entry loop and outlet looping can temporarily be stored in material pit and form and cushion, between plain net print zone and two material pits, be provided with PLC and control shear gauge, for control two steel bands between material pit when with plain net press printing, halt and be completed for printing after the printing position of advancing.
Control between shear gauge and be also provided with slewing rollers at described material pit and PLC, so that steel band is from material pit steering horizontal or turn to material pit from level.
Before described winder, be also provided with plate shearing machine, to require shear rolling according to product length.
Plate shearing machine after described uncoiler and uncoiler is two groups, does not shut down so that be used alternatingly production line while ensureing to change stock roll.
After described outlet looping and before being positioned at rolling, be also disposed with painting machine, curing oven, cooler.
The invention has the beneficial effects as follows: in the present invention by install plain net printing machine additional on steel-plate continuous production line, with be provided with material pit and PLC before and after the plain net printing machine and control shear gauge, can realize the production technology of steel band continuous printing, thereby improve production efficiency, made plain net printing technology can be applied to steel-plate continuous production line to produce multicolour pattern color steel.
Brief description of the drawings
The structural representation that Fig. 1 (a) is second half section production line of the present invention;
The structural representation that Fig. 1 (b) is first half section production line of the present invention;
In figure: 1 uncoiler, 2 pinch rolls, 3 plate shearing machines, 4 splicing machines, 5 first tensioners, 6 entry loops, 7 second tensioners, 8 slewing rollers, 9 the one PLC control shear gauge, 10 plain net print zone, and 11 the 2nd PLC control shear gauge, 12 the 3rd tensioners, 13 outlet loopings, 14 the 4th tensioners, 15 chemical painting machines, 16 curing ovens, 17 coolers, 18 the 5th tensioners, 19 winders, 20 material pits.
Detailed description of the invention
The present invention is described further by reference to the accompanying drawings:
As shown in the figure, Fig. 1 (a) connects and forms steel band continuous printing production line with the tail prime minister of Fig. 1 (b), comprise uncoiler 1, plate shearing machine 3, splicing machine 4, entry loop 6, plain net printing machine, outlet looping 13, chemistry painting machine 15, curing oven 16, cooler 17 and winder 19, above-mentioned each equipment is arranged successively by the transport path of steel strip printing, steel band is supported by steel band roller, the steel band each printing equipment of pile warp successively that leads, between plain net printing machine and entry loop 6 and outlet looping 13, be respectively provided with a material pit 20, between plain net print zone 10 and material pit 20, be respectively arranged with a PLC and control shear gauge 9, the 2nd PLC controls shear gauge 11 and slewing rollers 8, wherein uncoiler 1 and plate shearing machine 3 are two groups, on every processing uncoiler 1 and plate shearing machine 3, there is respectively steel band pile warp.
Two groups of steel bands are after uncoiler 1 and plate shearing machine 3, the taking the lead of steel band merges in splicing machine 4 places with connection end to end, by the first tensioner 5, the second tensioner 7, the 3rd tensioner 12, the 4th tensioner 14 and more than 18 tensioner of the 5th tensioner are set up dynamical system completely moves steel band continuously, gateway kink plays the temporary transient effect that stores steel band in the time of change of lap in continuous production, entry loop 6 always keeps certain reserves of steel band in the time of normal operation, steel band in the time of splicing machine 4 tape splicing before entry loop 6 need to stop, at this moment entry loop 6 is opened a steel band of putting the storage of cover handle is released, the steel band that utilizes in addition material pit 20 to store ensures the continuous operation of print zone, enter printing machine through slewing rollers 8 again and carry out stamp, PLC controls scale function and guarantees accurately carrying out of printing, after completing, steel band stamp enters another material pit 20, steel band can be stored equally, ensure the continuous operation of winder 19 print zone in the time of bundling below, enter again outlet looping 13, at this moment outlet looping 13 start to fill cover print zone continuously the steel band of operation here store, then be coated with one deck immersion coating through chemical painting machine in steel strip surface and increase the adhesion of printing coating, make coated and dried through curing oven 16 again, after printing machine, be provided with curing oven 16 and carry out solidifying of coating, cooler 17 adopts water-cooling groove, water-cooling groove carries out the cooling of coating, finally complete the pattern of steel band, enter plate shearing machine 3 sub-cut steel bands, after sub-cut, thereby steel band enters winder 19 and realizes the tinuous production of steel band through pinch roll 2 feedings.
While controlling steel plate printing between the kinks of shear gauge control gateway by two PLC, stop realizing plain net printing temporarily; after being completed for printing, can realize Fast Marching and carry out next section of printing; storing and the buffering of material pit 20 in the time of flat stamping in addition; can realize miscellaneous equipment in printing process and not shut down, realize continuous production and printing on steel-plate continuous production line with plain net printing machine.
