Embodiment
Below in conjunction with Figure of description the utility model is described in detail:
See Fig. 1, Fig. 2, Fig. 3, top roll car 3 arranged beneath cross moving tracks, top roll car 3 is traversing by Driven by Hydraulic Cylinder, and two positions in new roller received bit and top roll position are set.The cylinder body of work roll changing hydro-cylinder 1 is fixed with pressing plate, and work roll changing hydro-cylinder 1 bar head is connected with locking latches 2.Top roll car 3 and work roll changing hydro-cylinder 1 are arranged in the back side 16 of polishing machine, and compact construction is convenient to the maintenance of equipment.Working roll connects the fore side 15 that roller car 8 is arranged in polishing machine, receives the old roller that the new roller of quilt ejects, and the interior orbital docking of track and polishing machine is arranged on the top roll car 3, realizes the steady, accurately quick smoothly of top roll.The working roll of fore side 15 connects roller car 8 and is provided with orbital docking in track and the polishing machine, realize receiving old roller smoothly steadily, accurately fast.
Support roller of polishing machine roll change hydro-cylinder 7 is arranged in the fore side 15 of polishing machine, and the machine outside track 5 that roll change is used docks with machine inner orbit 4, and the roll change of support roller of polishing machine connects the inboard of the automobile-used track of roller with orbital arrangement at the polishing machine working roll, and is rationally distributed.Support roller of polishing machine roll change hydro-cylinder 7 is horizontally disposed, and cylinder body is fixed with pressing plate, and the hydraulic cylinder rod head connects with lower backing roll 14 usefulness bearing pins, makes it simple in structure, and is not fragile, safe and reliable to operation.
The locking latches that work roll changing is used mainly is comprised of the support 9 of cutting somebody's hair, locking cylinder 10, roller 11, claw 12.The support 9 of cutting somebody's hair adopts bearing pin to connect with work roll changing hydro-cylinder 1 bar head, and is simple and practical.Be provided with four pair rollers 11 in the bottom of the support 9 of cutting somebody's hair, roller is gripper rail about in the of 11, has played guide effect, makes work roll changing hydro-cylinder 1 push more steady and smooth of working roll.Locking cylinder 10 drives the draw-in groove of claw 12 locking working roll roller ends, makes working roll in the process of roll change, and safer, the position of roll change is more accurate.
The supporting roll roll change has been carried out special C shape groove design with C shape frame 6, under the prerequisite of proof strength, when making the band steel online, also can realize the replacing of support roller of polishing machine.The supporting roll roll change is that after changing supporting roll, supporting roll does not need to carry out the secondary adjustment in polishing machine again, has reduced the time like this by the physical dimension design of working roll with the profile of C shape frame 6, and the position is accurate.
When changing working roll, at first after the top roll car 3 top roll aligned position, the new roller of lock roller arrangement 2 lockings promotes new roller by work roll changing hydro-cylinder 1, and new roller ejects the old roller in the polishing machine, and the polishing machine opposite side connects roller car 8, receives old roller.Roll change mechanism utilization lock roller arrangement 2 aligns the position of new roller by Driven by Hydraulic Cylinder, and locking bail lifts and resets afterwards, and roll change work is finished.This system has realized that roll change is steady, has improved polishing machine roll change speed, has shortened roll changing time, has improved production operational availability.When changing supporting roll, first C shape frame 6 is encased inside between the upper and lower supporting roll 13,14, then utilize supporting roll roll change hydro-cylinder 7 to push new supporting roll in polishing machine, after upper backup roll 13 fixes, release C type frame by work roll changing hydro-cylinder 1 again, hang away with overhead traveling crane, finish the online replacing of supporting roll.
The utility model guarantees roll change safe and reliable of polishing machine, and the position is accurate, and roll changing time is short, has improved production efficiency, and is simple in structure, easy to maintenance, easy-to-operate.
Above embodiment limits the utility model never in any form, and every other improving and applying that above embodiment is made in the equivalent transformation mode all belongs to protection domain of the present utility model.
