Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1 to 4, the present invention comprises a roll stand 1; a driven roller 11 and a driving roller 12 are arranged on the frame 1; the driven roll 11 and the driving roll 12 are both horizontally arranged, the central axes of the driven roll 11 and the driving roll 12 are in the same vertical plane, the driven roll 11 and the driving roll 12 are both rotatably arranged on the rack 1, and a gap is reserved between the driven roll 11 and the driving roll 12 and used for allowing a raw material to be rolled to pass through; the shaft of the driving roller 12 is provided with an adjusting wheel 2; the adjusting wheel 2 is provided with an inner ring and an outer ring, the inner ring is fixedly connected with the driving roll 12, and the inner ring is fixedly connected with the outer ring through a plurality of groups of adjusting components which are uniformly distributed along the circumferential direction; the adjusting components comprise a limiting rod 22, a spring 21, a sliding block 23 and connecting plates 26, each group of adjusting components comprises two connecting plates 26, and two ends of each connecting plate 26 are respectively fixedly connected with an inner ring and an outer ring of the adjusting wheel 2 and symmetrically arranged along the radius direction of the adjusting wheel 2; the limiting rod 22 is arranged along the radius direction of the adjusting wheel, and two ends of the limiting rod are respectively fixedly connected with the inner ring and the outer ring of the adjusting wheel 2 and are positioned between two connecting plates 26 in each group of adjusting components; the spring 21 is sleeved on the limiting rod 22, one end of the spring 21 is fixedly connected with the outer ring, the other end of the spring 21 is fixedly connected with a wedge-shaped or cylindrical sliding block 23, and the sliding block 23 is extruded on the inner ring; the spring 21 with suitable strength is selected to normally drive the adjusting wheel 2 to rotate when the proper compression occurs, i.e. when the force application surface 25 of the sliding block 23 is completely contacted with the driving rod 31, so that the rolling mill normally works. The length of the sliding block 23 is larger than the width of the adjusting wheel 2; the driving roller 12 shaft is also sleeved with a driving wheel 3, the driving wheel 3 and the driving roller 12 shaft can rotate relatively, a driving rod 31 is arranged on the driving wheel 3, and the driving rod 31 and the sliding block 23 are matched to drive the adjusting wheel 2 to rotate; the corners of the slide block 23 contacting the driving rod 31 are rounded, so that the driving rod 31 pushes the slide block 23 to move. In the normal working state, the driving rod 31 and the sliding block 23 are in surface contact through the force application surface 25, and when the rolling mill clamps steel and the adjusting wheel 2 is adjusted, the driving rod 31 and the sliding block 23 are in surface contact. The other end of the driving wheel 3 is fixedly connected with a driving device.

The utility model discloses a theory of operation: in the shutdown state of the rolling mill, the motor does not apply force to the driving wheel 3, the driving rod 31 on the driving wheel 3 and the sliding block 23 on the adjusting wheel 2 are not extruded, the length of the spring 21 in the adjusting component on the adjusting wheel 2 is the largest, and the sliding block 23 is extruded on the inner ring of the adjusting wheel 2.

In the normal working state of the rolling mill, the motor drives the driving wheel 3 to rotate, the driving wheel 3 extrudes the sliding block 23 on the adjusting wheel 2 through the driving rod 31, when the force application surface 25 extruded to the sliding block 23 is completely contacted with the driving rod 31 on the driving wheel 3, at the moment, the spring 21 deforms, the force extruded on the sliding block 23 is the same as the force driven by the motor to rotate the driving rod 31 in the component force direction, the moving state of the sliding block 23 is kept stable, and the rolling mill normally works.

When the rolling mill is blocked by steel, the driving roll 12 is blocked by the steel, the force of the motor on the driving rod 31 is not enough to drive the adjusting wheel 2 to rotate, but the motor still works normally, at the moment, the motor continues to drive the driving wheel 3 to rotate, the driving rod 31 continues to rotate, and the adjusting wheel 2 cannot rotate, so that the driving rod 31 starts to push the sliding block 23 to move towards the outer ring direction, namely, the force application point of the driving rod 31 acting on the adjusting wheel 2 moves towards the outer ring direction of the adjusting wheel 2, under the condition that the output force of the motor is not changed, the force arm of the acting force of the motor driving the adjusting wheel 2 is lengthened, namely, the force applied on the adjusting wheel 2 by the motor is increased, so that the force applied on the driving roll 12 is increased, the driving roll 12 overcomes the steel blocking point, continues to rotate, the steel blocked is discharged, and the problem of steel blocking is solved.

After the rolling of the steel plate of the steel card is finished and the rolling mill is unloaded, the spring 21 starts to be released, so that the driving roll 12 rotates faster than the driving wheel 3 until the spring 21 is released to a normal working state.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
