Leather is printed as cover system
Technical field
The present invention relates to the technical field that the leather air brushing is printed, particularly relate to a kind of leather and be printed as cover system.
Background technology
When the leather air brushing is printed in the prior art, the main dependence that unreels of leather is manually controlled and is unreeled, its complicated operation, take manually more, and unreeling quality can not guarantee, because leather itself has elasticity, therefore require to go up the preceding end leather of chopping machine and can not be in tensioning state, necessary no tension force has so just more improved the difficulty that manually unreels, simultaneously because the inside of the leather of PU material has powder and dust, before last chopping machine, should carry out dedusting, existing dedusting operation is to rely on the artificial adhesive tape binding dust that passes through, and whole dust removal process is slow, fatigue, and dust removing effects is poor; Its wrapup procedure also is so in addition, haves much room for improvement.

The specific embodiment
Embodiment: referring to Fig. 1-14, a kind of leather is printed as cover system among the figure, comprise chopping machine, no tension force, dedusting unwinding device, no tension rolling device, described no tension force, dedusting unwinding device and do not have the both sides that the tension rolling device lays respectively at chopping machine, leather is emitted from no tension force, dedusting unwinding device, after printing, packed up by no tension rolling device chopping machine
Described no tension force, dedusting leather unwinding device comprise the frame first, load bearing roller first, live roll, the Roller for sticking dust on frame first top are set, the surperficial tangent installation of described live roll and Roller for sticking dust, be provided with leather detection probe and following leather detection probe in the live roll lower framework first outside, the axle head of described live roll and load bearing roller first is connected with driver train respectively; Also be provided with adjusting mechanism in frame first bottom, this adjusting mechanism comprises rocker, stationary roll, dancer rools, stationary roll is installed on the frame, rocker is sleeved on the stationary roll, the other end of rocker is equipped with dancer rools, dancer rools can be axis swing with the stationary roll with rocker, is positioned at dancer rools path of motion in the frame first and is provided with adjusted roller detection probe and following dancer rools detection probe; One end of frame first is provided with automatically controlled part first, last leather detection probe, following leather detection probe, adjusted roller detection probe, following dancer rools detection probe connect automatically controlled part first by lead, automatically controlled part first connects driver train by lead, leather is installed on the load bearing roller first, after walking around dancer rools downwards, be folded to the slit of passing between live roll and the Roller for sticking dust;
Described no tension force leather wrap-up comprises frame second, rack-mounted load bearing roller second and two idler rollers third and fourth, described load bearing roller second is installed in top one side of frame second, described two idler rollers third and fourth are installed in the opposite side on frame second top, the frame second bottom of described two idler rollers third and fourth one side is provided with leather detection probe third, leather passes the back on load bearing roller second from the slit between two idler rollers third and the fourth, load bearing roller second is connected with driver train, also be provided with automatically controlled part second on the frame first, this automatically controlled part second respectively with driver train, leather detection probe third connects; Described automatically controlled part second is arranged on an end of frame second.
The bottom of the live roll of described no tension force, dedusting leather unwinding device is provided with the idler roller first, and leather is folded to the back earlier through the tensioning of idler roller first by dancer rools, and then passes the slit between live roll and the Roller for sticking dust.
The part at side frame edge is provided with idler roller second outside the bottom of the live roll of described no tension force, dedusting leather unwinding device, and the slit leather that passes between live roll and the Roller for sticking dust rides over above the idler roller second.
The Roller for sticking dust outer felt of described no tension force, dedusting leather unwinding device around multilayer glue towards outer adhesive tape.
The working process of this system:
Leather volume to be printed is installed on the load bearing roller first, the leather stub bar drawn be folded to after walking around dancer rools downwards, walk around idler roller second, pass slit between driven roller and the Roller for sticking dust again, ride over above the idler roller first, the stub bar of leather passes chopping machine, will pass between two idler rollers third and fourth from the leather that chopping machine gets off, and the leather stub bar is fixed on the load bearing roller second
At first start no tension force, dedusting unwinding device, driver train drives the load bearing roller first and unreels, and when dancer rools was positioned at nadir, namely dancer rools and following dancer rools detection probe were at once, and driver train drives the load bearing roller first to be stopped to unreel; When dancer rools was positioned at vertex, namely dancer rools and adjusted roller detection probe were at once, and driver train rotates, and the load bearing roller first begins to unreel; In addition when the leather between idler roller first and the chopping machine is sagging when being higher than the leather detection probe, driver train drives the driven roller first and rotates, and the leather of dancer rools one side is transported to chopping machine one side, in the process of carrying, passed through Roller for sticking dust owing to leather, the dust of leather surface is adsorbed, and has finished dust removal process; When the leather between idler roller first and the chopping machine is sagging when being lower than down the leather detection probe, driver train stops operating, when treating that leather between idler roller first and the chopping machine is sagging and being higher than the leather detection probe again, driver train moves again, and motion realizes that no tension force unreels so repeatedly; The rotation of driven roller can make the leather length of dancer rools one side change, and the position of dancer rools is changed, thereby realizes the driving to the load bearing roller first.
Before no tension rolling device starts, to between two idler rollers third and fourth, pass from the leather that chopping machine gets off earlier, and the leather end is fixed on the load bearing roller second, after starting no tension rolling device, chopping machine is printed on one side, on one side the leather on top is carried downwards, leather is owing to conduct oneself with dignity and can progressively fall, when treating that leather drops to the position of leather detection probe third (as Figure 13), leather detection probe third detects leather, produces signal and passes to automatically controlled part second, and automatically controlled part second control load bearing roller second is rotated a period of time, leather is wrapped in (as Figure 14) on the load bearing roller second, and the rotation time of load bearing roller second can freely be set.
