No-station pole canopy, dedusting leather unwinding device
Technical field
The present invention relates to the technical field of leather inkjet printing, particularly relate to a kind of no-station pole canopy, dedusting leather unwinding device.
Background technology
In prior art during leather inkjet printing, the main dependence that unreels of leather is manually carried out control and is unreeled, its complicated operation, take manually more, and unreel quality can not ensure, because leather itself has elasticity, therefore require that one end leather before upper chopping machine can not be in tensioning state, necessary no-station pole canopy, so just more improve the difficulty manually unreeled, simultaneously because the inside of the leather of PU material is with powder and dust, dedusting should be carried out before upper chopping machine, existing dust-removing process relies on manually by adhesive tape binding dust, whole dust removal process is slow, tired, and dust removing effects is poor.
Summary of the invention
The object of the invention is to solve the problem, a kind of no-station pole canopy, dedusting leather unwinding device are provided.
Technical scheme of the present invention is: a kind of no-station pole canopy, dedusting leather unwinding device, comprise frame, the load bearing roller of upper rack, live roll, Roller for sticking dust are set, it is characterized in that: the plane tangent of described live roll and Roller for sticking dust is installed, outside live roll lower framework, be provided with leather detection probe and lower leather detection probe, described live roll and the axle head of load bearing roller are connected to driver train; Also adjusting mechanism is provided with in frame lower, this adjusting mechanism comprises rocker, stationary roll, dancer rools, stationary roll is arranged in frame, one end of rocker is sleeved on stationary roll, the other end of rocker is provided with dancer rools, dancer rools can be axis swing with stationary roll with rocker, frame is positioned in dancer rools path of motion and is provided with dancer rools 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, upper dancer rools detection probe, lower dancer rools detection probe connect automatically controlled part by wire, automatically controlled part connects driver train by wire, leather is arranged on load bearing roller, after walking around dancer rools downwards, roll over the gap be upward through between live roll and Roller for sticking dust.
The bottom of described live roll is provided with idler roller first, and leather is folded to upper rear elder generation through the tensioning of idler roller first by dancer rools, and then through the gap live roll and Roller for sticking dust.
The part at the lower outside frame edge of described live roll is provided with idler roller second, rides over above idler roller second through the gap leather live roll and Roller for sticking dust.
Described Roller for sticking dust outer felt around multilayer glue towards outer adhesive tape.
Beneficial effect of the present invention
This no-station pole canopy, dedusting leather unwinding device, can realize no-station pole canopy and automatically unreel by leather, and can automatic dust removing while unreeling, good dedusting effect.

Detailed description of the invention
Embodiment: see Fig. 1-7, a kind of no-station pole canopy, dedusting leather unwinding device in figure, comprise frame, the load bearing roller of upper rack, live roll, Roller for sticking dust are set, it is characterized in that: the plane tangent of described live roll and Roller for sticking dust is installed, outside live roll lower framework, be provided with leather detection probe and lower leather detection probe, described live roll and the axle head of load bearing roller are connected to driver train; Also adjusting mechanism is provided with in frame lower, this adjusting mechanism comprises rocker, stationary roll, dancer rools, stationary roll is arranged in frame, one end of rocker is sleeved on stationary roll, the other end of rocker is provided with dancer rools, dancer rools can be axis swing with stationary roll with rocker, frame is positioned in dancer rools path of motion and is provided with dancer rools 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, upper dancer rools detection probe, lower dancer rools detection probe connect automatically controlled part by wire, automatically controlled part connects driver train by wire, leather is arranged on load bearing roller, after walking around dancer rools downwards, roll over the gap be upward through between live roll and Roller for sticking dust.
The bottom of described live roll is provided with idler roller first, and leather is folded to upper rear elder generation through the tensioning of idler roller first by dancer rools, and then through the gap live roll and Roller for sticking dust.
The part at the lower outside frame edge of described live roll is provided with idler roller second, rides over above idler roller second through the gap leather live roll and Roller for sticking dust.
Described Roller for sticking dust outer felt around multilayer glue towards outer adhesive tape.
Working process:
Leather to be printed volume is arranged on load bearing roller, leather stub bar is drawn after walking around dancer rools downwards and be folded to, walk around idler roller second, then through gap driven roller and Roller for sticking dust, ride over above idler roller first, the stub bar of leather is finally installed on a printer, after starting this device, driver train drives load bearing roller to unreel, when dancer rools is positioned at nadir, namely dancer rools drives load bearing roller to stop unreeling with lower dancer rools detection probe to driver train time corresponding; When dancer rools is positioned at vertex, namely dancer rools rotates driver train time corresponding with upper dancer rools detection probe, and load bearing roller starts to unreel; Leather in addition between idler roller first and chopping machine sagging higher than upper leather detection probe time, driver train drives driven roller to rotate, and the leather of dancer rools side is transported to chopping machine side, because leather have passed through Roller for sticking dust in the process of conveying, the dust of leather surface is adsorbed, and completes dust removal process; Leather between idler roller first and chopping machine sagging lower than lower leather detection probe time, driver train stops operating, leather between roller first to be tensioned and chopping machine sagging again higher than upper leather detection probe time, driver train is action again, and motion realizes no-station pole canopy and unreels so repeatedly; The rotation of driven roller can make the leather length of dancer rools side change, and the position of dancer rools is changed, thus realizes the driving to load bearing roller.
