Detailed description of the invention
As it is shown in figure 1, the present embodiment slitting line afterbody galvanized steel plain sheet tensioner includes lifting pressure roller 1, fixing roller 2 and movable roll 3, also include the hydraulic locking apparatus for described movable roll 3 being locked in operating position；The diameter of described lifting pressure roller 1 is 200 millimeters, and the diameter of described fixing roller 2 and described movable roll 3 is 500 millimeters.Described fixing roller 2 is between described lifting pressure roller 1 and described movable roll 3；Galvanized steel plain sheet 4 is successively between described lifting pressure roller 1 and described fixing roller 2, and enters coiling machine 5 between described fixing roller 2 and described movable roll 3；The work surface that described lifting pressure roller 1, described fixing roller 2 contact with described galvanized steel plain sheet 4 with described movable roll 3 is provided with flexible material (adopting polyurethane in the present embodiment, described lifting pressure roller 1, described fixing roller 2 and described movable roll 3 are polyurethane roller).
The axis of the axis of described lifting pressure roller 1, the axis of described fixing roller 2 and described movable roll 3 is all in same numerical value plane and be parallel to each other；Described lifting pressure roller 1 is positioned at the top of described fixing roller 2, and described lifting pressure roller 1 can be risen or fallen by relatively described fixing roller 2 by Driven by Hydraulic Cylinder；Described movable roll 3 passes through Driven by Hydraulic Cylinder, it is possible to the axis of described fixing roller 2 is that axle rotates.
The transmission side of described movable roll 3 and the transmission side of described fixing roller 2 are respectively arranged with magnetic powder brake, in order to described movable roll 3 and described fixing roller 2 are braked.
Utilize the galvanized steel plain sheet tensioning method for coiling of above-mentioned slitting line afterbody galvanized steel plain sheet tensioner, comprise the steps:
A () regulates threading gap: lifting pressure roller 1 makes to be formed therebetween the gap for galvanized steel plain sheet 4 traverse away from fixing roller 2；Movable roll 3 is rotary moveable roller, and rotary moveable roller moves to the galvanized steel plain sheet 4 outlet top between described lifting pressure roller 1 and described fixing roller 2 so that form the gap for galvanized steel plain sheet 4 traverse between described rotary moveable roller and described fixing roller 2；
(b) threading: described galvanized steel plain sheet 4 first from right side from traverse between described lifting pressure roller 1 and described fixing roller 2, to the left side of described lifting pressure roller 1 and described fixing roller 2；Then enter between described fixing roller 2 and described movable roll 3 around described fixing roller 2 on the left of described fixing roller 2, to the right side of described fixing roller 2 and described movable roll 3；Finally enter into, around described movable roll 3, the coiling machine 5 being positioned on the left of described movable roll 3 on the right side of described movable roll 3；
C () tensioning: described galvanized steel plain sheet 4 is nipped after described coiling machine 5, described lifting pressure roller 1 is near described fixing roller 2 so that described galvanized steel plain sheet 4 is pressed between described lifting pressure roller 1 and described fixing roller 2；Described rotary moveable roller moves to below described fixing roller 2 so that described galvanized steel plain sheet 4 forms S type parcel district between described lifting pressure roller 1 and described fixing roller 2 between below described rotary moveable roller.In the galvanized steel plain sheet tensioning method for coiling of the present embodiment, for the ease of threading and realize quick threading, by described movable roll 3 with the axis of described fixing roller 2 for axle, rotate (counterclockwise) 155 degree in the left side of described fixing roller 2 to described lifting pressure roller 1；So when threading, described galvanized steel plain sheet 4 is positioned at below described movable roll 3 between described lifting pressure roller 1 and described fixing roller 2 after traverse, then described galvanized steel plain sheet 4 is directly entered described coiling machine 5 described coiling machine 5 of being nipped, then pass through and lift pressure roller 1 described in Driven by Hydraulic Cylinder and drop to described galvanized steel plain sheet 4 is pressed between described lifting pressure roller 1 and described fixing roller 2, and reversely rotated immediately below described fixing roller 2 by movable roll 3 described in Driven by Hydraulic Cylinder and by hydraulic locking apparatus, described movable roll 3 locked, prevent from described coiling machine 5 from batching movable roll 3 described in the process of described galvanized steel plain sheet 4 be moved or rock.Described hydraulic locking apparatus can adopt structure well known in the prior art, for instance: the hook on hydraulic cylinder piston rod can be utilized to hook the axle of described movable roll 3；It is of course also possible to take in prior art other that described movable roll 3 can be locked in the device of this position.
It is polyurethane roller due to described lifting pressure roller 1, described fixing roller 2 and described movable roll 3 and described lifting pressure roller 1, described fixing roller 2 and described movable roll 3, with described galvanized steel plain sheet 4, relative sliding all will not occur, it is thus advantageous to completely retain described galvanized steel plain sheet 4 surface zinc flower and plate face fineness, it is advantageously implemented threading automatization and reduces labor strength, raising labour productivity and product quality.Impurity will not be produced, from without manually described galvanized steel plain sheet 4 surface being cleared up on described galvanized steel plain sheet 4 surface.
Above-described embodiment is only for clearly demonstrating the invention example, and is not the restriction to the invention detailed description of the invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here without also cannot all of embodiment be given exhaustive.And the apparent change thus amplified out or variation are still among the invention scope of the claims.
