Without tension force, dedusting leather unwinding device
Technical field
The present invention relates to the technical field of leather inkjet printing, particularly relate to a kind of without tension force, dedusting leather unwinding device.
Background technology
In the prior art during leather inkjet printing, 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 the front end leather of upper chopping machine can not be in tensioning state, must be without tension force, so just more improve the difficulty that manually unreels, simultaneously since the inside of the leather of PU material with powder and dust, before upper 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.
Summary of the invention
To the objective of the invention is in order addressing the above problem, to provide a kind of without tension force, dedusting leather unwinding device.
Technical scheme of the present invention is: a kind of without tension force, dedusting leather unwinding device, comprise frame, load bearing roller, live roll, the Roller for sticking dust of upper rack are set, it is characterized in that: the surperficial tangent installation of described live roll and Roller for sticking dust, leather detection probe and lower leather detection probe on the live roll lower framework outside, the axle head of described live roll and load bearing roller is connected with respectively driver train; Also be provided with adjusting mechanism in frame lower, 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 with rocker take stationary roll as axis swing, be positioned at dancer rools path of motion in frame and be provided with adjusted roller detection probe and lower dancer rools detection probe; One end of frame is provided with automatically controlled part, upper leather detection probe, lower leather detection probe, adjusted roller detection probe, lower dancer rools detection probe connect automatically controlled part by wire, automatically controlled part connects driver train by wire, leather is installed on the load bearing roller, after walking around dancer rools downwards, be folded to the slit of passing between live roll and the Roller for sticking dust.
The bottom of described live roll is provided with the idler roller first, and leather is folded to upper rear elder generation 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 the lower outside frame edge of described live roll is provided with idler roller second, and the slit leather that passes between live roll and the Roller for sticking dust rides over above the idler roller second.
Described Roller for sticking dust outer felt around multilayer glue towards outer adhesive tape.
Beneficial effect of the present invention
This is without tension force, dedusting leather unwinding device, can realize automatically unreeling without tension force by leather, and can automatic dust removing when unreeling, good dedusting effect.

The specific embodiment
Embodiment: referring to Fig. 1-7, a kind of without tension force, dedusting leather unwinding device among the figure, comprise frame, load bearing roller, live roll, the Roller for sticking dust of upper rack are set, it is characterized in that: the surperficial tangent installation of described live roll and Roller for sticking dust, leather detection probe and lower leather detection probe on the live roll lower framework outside, the axle head of described live roll and load bearing roller is connected with respectively driver train; Also be provided with adjusting mechanism in frame lower, 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 with rocker take stationary roll as axis swing, be positioned at dancer rools path of motion in frame and be provided with adjusted roller detection probe and lower dancer rools detection probe; One end of frame is provided with automatically controlled part, upper leather detection probe, lower leather detection probe, adjusted roller detection probe, lower dancer rools detection probe connect automatically controlled part by wire, automatically controlled part connects driver train by wire, leather is installed on the load bearing roller, after walking around dancer rools downwards, be folded to the slit of passing between live roll and the Roller for sticking dust.
The bottom of described live roll is provided with the idler roller first, and leather is folded to upper rear elder generation 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 the lower outside frame edge of described live roll is provided with idler roller second, and the slit leather that passes between live roll and the Roller for sticking dust rides over above the idler roller second.
Described Roller for sticking dust outer felt around multilayer glue towards outer adhesive tape.
Working process:
Leather volume to be printed is installed on the load bearing roller, the leather stub bar drawn be folded to after walking around dancer rools downwards, walk around idler roller second, pass again slit between driven roller and the Roller for sticking dust, ride over above the idler roller first, the stub bar of leather is installed on the chopping machine at last, after starting this device, driver train drives load bearing roller and unreels, when dancer rools is positioned at nadir, be dancer rools and lower dancer rools detection probe at once, driver train drives load bearing roller 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 load bearing roller begins to unreel; In addition when the leather between idler roller first and the chopping machine is sagging when being higher than upper leather detection probe, driver train drives driven roller 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 lower leather detection probe, driver train stops operating, when treating that leather between idler roller first and the chopping machine is sagging and again being higher than the leather detection probe, driver train moves again, and motion realizes unreeling without tension force 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 load bearing roller.
