Detailed Description

In order to further describe the technical means and effects adopted by the present utility model for achieving the intended purpose, the following detailed description will refer to the specific implementation, structure, characteristics and effects according to the present utility model with reference to the accompanying drawings and preferred embodiments.

Example 1:

As shown in fig. 1, the utility model discloses a silicon steel tensioning and conveying device, which comprises a first supporting roller 3, a second supporting roller 4, a tensioning roller 5, a base 1, a fixing frame 9, a vertical downward hydraulic cylinder 10 and a sliding block 6, wherein the first supporting roller 3 and the second supporting roller 4 are arranged on the base 1 through two end brackets 2, the tensioning roller 5 is arranged on the base 1 between the first supporting roller 3 and the second supporting roller 4 through a mounting frame 18, the sliding groove 7 is arranged on the mounting frame 18, the sliding block 6 is arranged in the sliding groove 7, the end part of the tensioning roller 5 is rotationally connected with the sliding block 6, the fixing frames 9 are arranged on the bases 1 at the two ends of the tensioning roller 5, and the end parts of the hydraulic cylinders 10 are connected with the sliding block 6; the base 11 is arranged at the bottom of the base 1, at least three screws 19 are arranged on the base 11, screw holes are formed in the base 1 and correspond to the screws 19, the screws 19 penetrate through the base 1 through the screw holes, the motor 14 is arranged on the base 11, belt wheels 12 are arranged on the output shaft of the motor 14 and the end parts of the screws 19, and all the belt wheels 12 are in transmission connection through the belt 13.

Wherein the heights of the first supporting roller 3 and the second supporting roller 4 at the two ends of the base 1 are kept basically consistent, and the normal height of the tensioning roller 5 can be slightly lower than the horizontal height of the first supporting roller 3 and the second supporting roller 4. The silicon steel coiled material is conveyed forward from above the first supporting roller 3, below the tensioning roller 5 and above the second supporting roller 4 once. Normally, the tensioning roller 5 moves downwards under the action of the hydraulic cylinder 10, so that the position of the tensioning roller 5 is lower than that of the first supporting roller 3 and the second supporting roller 4, and the distance is increased, so that the tensioning force on the silicon steel coiled material is increased. When the silicon steel coiled material looseness degree is large, the tension roller 5 needs excessive displacement to keep the tension force requirement of the silicon steel coiled material, and the excessive displacement can cause the bending degree of the silicon steel coiled material at the tension roller 5 to be too large, so that the product quality is affected. At this time, the motor 14 is required to rotate, and all the screws 19 are rotated synchronously by the belt wheel 12 and the belt 13, so that the base 1 can be lowered, and the silicon steel coiled materials except the first support roller 3 and the second support roller 4 can be lowered in the process of lowering the base 1, so that the tension of the whole silicon steel coiled material can be improved under the condition that the bending degree of the silicon steel coiled material at the tension roller 5 is not changed. Normally, the number of the screws 19 is preferably four, and the screws 19 are respectively located at four corners of the base 11, so that the four screws 19 enclose a rectangular structure, and the base 1 can be stably supported. The four belt wheels 12 at the bottom of the screw 19 are driven by an annular belt 13, and the motor 14 is used as a power source to drive all the screws 19 to synchronously move. The belt 13 may be a synchronous belt, and the pulley 12 may be a synchronous pulley, so as to ensure that all screws 19 rotate more stably and reliably.

A pressure spring 8 is arranged in the sliding chute 7 below the sliding block 6, the lower end of the pressure spring 8 is fixedly connected with a mounting frame 18 at the bottom of the sliding chute 7, and the upper end of the pressure spring 8 is fixedly connected with the sliding block 6. The pressure spring 8 is arranged below the sliding block 6, no matter where the sliding block 6 is located in the sliding groove 7, the sliding block 6 is always subjected to pressure from the hydraulic cylinder 10 and upward elastic force given by the pressure spring 8, so that the tensioning roller 5 can be always kept in a stable state at any position, and the tensioning effect on the silicon steel coiled material is stable and reliable.

The hydraulic cylinder 10 is provided with a pressure sensor 15, the base 1 and the sliding block 6 are provided with a distance sensor 16 matched with each other, the hydraulic cylinder further comprises a controller 17, the pressure sensor 15 and the distance sensor 16 are both connected with the controller 17, and the controller 17 is electrically connected with the motor 14. The pressure sensor 15 on the hydraulic cylinder 10 is used to determine the pressure exerted by the hydraulic cylinder 10 on the silicon steel coil, so that the tension can be determined. The cooperation between the distance sensor 16 can effectively detect the distance between the sliding block 6 and the base 1, so that the descending distance of the tensioning roller 5 can be determined, the maximum descending distance of the tensioning roller 5 can be set in the controller 17, when the position of the tensioning roller 5 descends to the maximum, the hydraulic cylinder 10 stops descending, the controller 17 drives the motor 14 to start, all screws 19 are driven by the motor 14 to rotate, the screws 19 can drive the whole base 1 to descend, and when the whole base 1 descends, silicon steel coiled materials on two sides of the base 1 are tensioned downwards, so that tensioning force is further improved.

The double tensioning control can be realized by the scheme, under the condition that the tensioning stability and the tensioning force are controllable, the overlarge bending degree of the silicon steel coiled material at the tensioning roller 5 caused by overlarge tensioning force can be effectively avoided, and therefore the performance of the silicon steel coiled material in the tensioning conveying process can be improved, and the product quality is improved.
