The device also comprises a backward bending roller which is positioned in front of the upper traction roller and the lower traction roller and can lift.
The anti-bending roll passes through the bearing and installs on the anti-bending axle, the both ends of anti-bending axle are fixed on the slider, the slider is located the fretwork hole of an end plate, be equipped with the spring between the upper end in slider and fretwork hole, the slider lower extreme is the inclined plane, the supporting wedge on inclined plane, the lead screw threaded connection that wedge and one can only the axle rotate, the one end of lead screw is equipped with first rocking wheel, and when rotating first rocking wheel, two wedges remove to opposite direction.
The utility model has the beneficial effects that:
the upper traction roller and the lower traction roller are arranged in a staggered mode, a steel coil is inclined when going down from the uncoiler and has a certain radian (particularly the end portion), the steel coil enters the horizontal conveying belt portion after passing through the upper traction pipe and the lower traction roller, the upper traction roller in the staggered mode presses the radian of the steel coil (the lower traction roller and the conveying belt portion are respectively used as two supporting points, the upper traction roller presses downwards), the radian is corrected, if the radian is not enough, the upper traction roller can be used for pushing upwards, and the radian can be basically corrected through the cooperation of the pressing and the pushing of the upper traction roller and the counter-bending roller.
Drawings
The utility model is further described with reference to the accompanying drawings in which:
FIG. 1 is a schematic front view of the present invention;
FIG. 2 is a left side view of the present invention;
FIG. 3 is a schematic sectional view of the reverse roll.
In the figure, 201 is an upper traction roller, 202 is a lower traction roller, 203 is a reverse bending roller, 204 is a reverse bending shaft, 205 is a sliding block, 206 is an end plate, 207 is a spring, 208 is an inclined surface, 209 is a wedge block, 210 is a lead screw, 211 is a first hand-operated wheel, and 212 is a cross arm.
Detailed Description
The drawings illustrate specific embodiments of the utility model. As shown in fig. 1 to 3, the drawing mechanism for unwinding, slitting and winding includes an upper drawing roller 201 and a lower drawing roller 202, which have the same diameter but have axes not on a vertical plane: the upper pulling roll 201 is arranged at the front and the rear of the lower pulling roll 202 (the travelling direction of the steel coil is used as the front), and specifically comprises the following steps: the ratio of the distance between the axis of the upper pull roll 201 and the axis of the lower pull roll 202 to the diameter of the upper pull roll 201 is 1: 36-60, for example, if the diameter of the upper pull roll 201 is 180 centimeters, the distance between the axis of the upper pull roll 201 and the axis of the lower pull roll 202 may be 30-50 millimeters.
A reverse bending roller 203 is arranged immediately in front of the traction mechanism 2, the reverse bending roller 203 can be lifted manually, and the structure is as follows: the two ends of the anti-bending roll 203 are respectively arranged on an anti-bending shaft 204 through bearings, the two ends of the anti-bending shaft 204 are respectively fixed on a sliding block 205, the sliding block 205 is positioned in a hollow hole of an end plate 206, a spring 207 is arranged between the sliding block 205 and the upper end of the hollow hole, and the upper end and the lower end of the spring 207 are respectively fixed on the sliding block 205 and the hollow hole; the lower end of the sliding block 205 is an inclined plane 208, the end of the inclined plane 208 close to the anti-bending roller 203 is lower, and the end far away from the anti-bending roller 203 is higher; the inclined surface 208 is matched with a wedge block 209, the wedge block 209 is in threaded connection with a lead screw 210, a first hand-operated wheel 211 is fixed at one end of the lead screw 210, the lead screw 210 can only rotate in a shaft mode and cannot move along the axial direction, the thread directions of the two wedge blocks 209 are opposite, that is, when the first hand-operated wheel 211 is rotated, the two wedge blocks 209 move in opposite directions, and are either closer to each other or farther from each other; the upper ends of the two end plates are fixedly connected through a cross arm 212.
The working process is as follows: the end of the steel coil enters the traction mechanism along the platform in front of the uncoiler, the steel plate at the front end is low in front and high in back at the moment, and is slightly bent, so that the bent part can be corrected by the staggered arrangement of the upper traction roller 201 and the lower traction roller 202, if the steel coil is not bent, the backward bending roller 203 in front is pushed upwards by shaking the first hand shaking wheel 211, the backward bending roller 203 is only used when needed, otherwise (generally after normal operation) the backward bending roller 203 is in a low-position state and cannot be pushed to the steel plate.
Other technical features than those described in the specification are known to those skilled in the art.
