The specific embodiment

In the embodiment shown in fig. 1, the utility model props up shaft device (5), rocking arm by unwinding device (1), adjustable roller arrangement (2), guide roller (3), draw-gear (4), rocking arm and crosses roller (6), slitting knife system (7), closes back and lead materials device (8), rocking arm (9), rocking arm support shelves (10), a hydraulic cylinder (11), wrap-up (12), main wall plate (13), wallboard support shelves (14) and a main power system 15) constitute.

Manual operation is drawn stub bar and is drawn material by process route from stock roll (16) volume face, props up shaft device (5), rocking arm by way of adjustable roller arrangement (2), guide roller (3), draw-gear (4) (this moment, described pressure roller was in a disengaged position), rocking arm and crosses roller (6), slitting knife system (7) (this moment, described upper and lower cutting knife was in the position of engagement), closes back and lead materials device (8) (lead material roller and be in a disengaged position this moment), rocking arm and cross on the described Scroll that roller (6) finally arrives described wrap-up (12) and overlap stub bar.In whole technical process, unwinding device (1) is used to install stock roll (16), and it is applied braking moment in that strip is in service, so that strip has and keeps required uncoiling tension.Adjustable roller arrangement (2) is used for operating strip both sides degree of tightness differed and carries out manual adjustments.Guide roller (3) is used for guiding and the support to strip.The described pressure roller of draw-gear (4) is finished at strip and is in the pressing position after connecting, and strip is applied certain pressure, and the traction strip moves ahead under the driving of active force.Rocking arm props up shaft device (5) divided by outside the swing gyroaxis of its described fulcrum as rocking arm (9), and the described roll body on it also is used as the guiding and the support of strip.Rocking arm is crossed roller (6) and is used for strip and enters guiding and support before the slitting.Slitting knife system (7) rolls in opposite directions under the situation that its cutting edge connects by its upper and lower cutting knife and finishes longitudinal shear to the process strip.Close back and lead the principle that materials device (8) utilizes before, during and after it three roller diameters of closing back to increase progressively in right amount successively and drags down and do under the interlock of identical gear separately the linear speed incremental motion with rotating speed in described active force, increase progressively the trace stretching of realization by strip successively in the frictional force on each roll surface, thereby avoid the ginseng dish phenomenon in the wrapup procedure the band in a narrow margin after shearing.Lead material roller under hydraulic oil cylinder driving by with described after close back roller to pressing, play initiatively draw when wearing material again, rolling is finished after, during the cutting material tail, depress this roller and play control material tail, so that new volume overlaps.Rocking arm on the rolling volume face is crossed roller (6) and is played guiding and card finishing function.Rocking arm (9), rocking arm support shelves (10), main wall plate (13) and wallboard support shelves (14) are structural member.Hydraulic cylinder device (11) is only given the cavity of resorption fuel feeding, and low pressure is used to control the pressure to the volume face, and high pressure is used for the rise that finished product volume (17) unloads rocking arm when rolling up.Wrap-up (12) carries out the rolling of finished product band under independent power drives.Main power system (15) is to be given draw-gear (4) simultaneously and close back and lead materials device (8) by belt transmission by a motor power is provided.

Embodiment shown in Figure 2 is the unwinding device (1) of absolute construction, whole unwinding device by a pair of unwinding rack (23) support and also is fastenedly connected by some foundation bolts (24) and ground.When stock roll is installed, big band opinion (28) synchronously, unreeling shaft (18), the radial bearing at two ends (21), the vertex of a cone of belt wheel end (19) and locknut (20) are normally as one, penetrate the centre bore of stock roll from no belt wheel end, refill the vertex of a cone (19) of the other end and locknut (20) and sidespin is moving inwards, after making the vertex of a cone (19) and stock roll clamping at two ends, the whole again radial bearing (21) by its two ends installs in the spindle socket that unreels (22) on the unwinding rack (23), refill band (27) synchronously, it is connected with small synchronous pulley (26) on the motor (25).When motor (25) is switched on, can make its rotation to applying torque on the stock roll by belt transmission.

Embodiment shown in Figure 3 is adjustable roller arrangement (2), and it is fastenedly connected by screw (29) and main wall plate (13).Slide (30) has two, installs in opposite directions in pairs, and big of one is gone up vertical direction and had one " U " shape chute.Slide block (32) has two, on big of the one spindle socket is arranged, and it matches with two sides and slide (30) " U " shape groove, and can slide up and down, and roll body (35) matches by radial bearing (31) and slide block (32) spindle socket with its bearings at both ends step.Manually rotation hand wheel (34) can pass through the flexible movable slider of stage clip (33) (32) to lower slider when moving downward, thereby realizes that height adjustable use in roll body (35) two ends needs.

Embodiment shown in Figure 4 is draw-gear (4), its afterbody of oil cylinder (37) by oil cylinder fulcrum (36) and main wall plate (13) for being articulated and connected, head is articulated and connected with pivoted arm (41) afterbody by joint (38) and bearing pin (39), pivoted arm (41) has a pair of, it is articulated and connected by pivoted arm fulcrum (40) and main wall plate (13) with mider hole, assemble with the shaft extension at pressure roller (42) two ends with head shaft pod and radial bearing (43), carry-over pinch rolls (47) by radial bearing (46) and main wall plate (13) assembling, stretch out main wall plate outer shaft extension by flat key (44) and traction belt wheel (45) assembling with it with its bearings at both ends step.When oil cylinder (37) front/back cavity difference fuel feeding, just drive pivoted arm (41) around pivoted arm fulcrum (40) swing, thereby realize pressure roller (42) the radially clutch action of carry-over pinch rolls (47) relatively, the adjusting charge oil pressure can be regulated radially pressure force therebetween, to satisfy the needs of different tractive force.
