The steel plate to be rolled is sent to the rotating wheel 543 by the placing plate 51, at the same time, the second motor 541 is started, so that the second motor 541 drives the rotating wheel 543 to rotate, the steel plate is sent to the first reel 41 while the rotating wheel 543 rotates, because the initial state of the rotating wheel 543 is attached to the placing plate 51, the rotating wheel 543 pushes the rotating wheel 543 to move upwards according to the thickness of the steel plate while transmitting the steel plate, so that the rotating wheel 543 drives the second toggle block 551 to slide upwards on the second slide rheostat 553 through the third slide block 542, and further the resistance value inside the second slide rheostat 553 is changed, the moving block 535 is driven to move upwards synchronously by the second motor 541 while the rotating wheel moves upwards, because the moving block 535 is provided with the groove corresponding to the magnetic force limiting block 534, the moving block 535 is clamped with the magnetic force limiting block 534 through the groove after moving upwards, the second toggle block 551 is fixed, so that the resistance of the second slide resistor 553 is stabilized.
Further, the magnetic field force limiting device further comprises a control switch 6, the control switch 6 is fixedly mounted on one side, away from the rack 1, of the connecting plate 21 and on the front side of the rectangular shell 31, the control switch 6 is electrically connected with the third coil 531, and the third coil 531 generates a magnetic field force attracted with the magnetic force limiting block 534 after current is introduced.
When the steel plate rolling operation is completed and the next steel plate is replaced, the worker presses the control switch 6, the control switch 6 is electrically connected with the third coil 531, so that current flows into the third coil 531, magnetic field force for attracting the magnetic force limiting block 534 is generated, and then the rotating wheel 543 is reset under the action of gravity.
The specific use mode and function of the embodiment are as follows:
when in use, firstly, the steel plate to be rolled is sent to the rotating wheel 543 from the placing plate 51, and at the same time, the second motor 541 is started, so that the second motor 541 drives the rotating wheel 543 to rotate, and the steel plate is sent to the first reel 41 while the rotating wheel 543 rotates, because the initial state of the rotating wheel 543 is attached to the placing plate 51, the rotating wheel 543 pushes the rotating wheel 543 to move upwards according to the thickness of the steel plate while transmitting the steel plate, so that the rotating wheel 543 drives the second poking block 551 to slide upwards on the second slide rheostat 553 through the third sliding block 542, and further the resistance value inside the second slide rheostat 553 is changed, and the moving block 535 is driven to move upwards synchronously through the second motor 541 while moving upwards through the rotating wheel 543, because the moving block 535 is provided with a groove corresponding to the magnetic force limiting block 534, so that the moving block 535 is blocked with the magnetic force limiting block 534 through the groove after moving upwards, the second toggle block 551 is fixed, so that the resistance of the second slide resistor 553 is stabilized.
Further, when the steel plate is fed to the first reel 41, the first motor 22 is started, so that the first motor 22 drives the first gear rod 23 to rotate, the first gear rod 23 is engaged with and drives the second gear rod 24 at the upper side to synchronously rotate while rotating, then the second gear rod 24 drives the first reel 41 fixedly connected with the second gear rod to rotate, then the steel plate is coiled under the cooperation of the second reel 42, when the second gear rod 24 rotates clockwise, the second gear rod 24 is engaged with and drives the rack rod 25 to move towards the rear side, so that the rack rod 25 drives the pressing block 264 to synchronously move backwards under the action of the first sliding block 261 and the connecting rod 263, when the steel plate reaches a specified distance in a single-pass coiling manner, the pressing block 264 is contacted with the pressing switch 265 at the rear side, and the pressing switch 265 is electrically connected with the first motor 22, so as to control the first motor 22 to reversely rotate, after the pressing block 264 on the front side is contacted with the pressing switch 265 on the front side, the first motor 22 is controlled to rotate forwards again, and the operation is repeated, so that the purpose of accurately controlling the distance of the one-way rolling plate is achieved, and the effects of automatically stopping to switch forward and backward rotation and simultaneously cutting off manual control are achieved.
Further, in the process of rolling the steel plate by the first reel 41 and the second reel 42, since the second toggle block 551 can adjust the upward sliding distance on the second slide rheostat 553 according to the thickness of the steel plate, the farther the upward sliding distance of the second toggle block 551 is, the larger the resistance value inside the second slide rheostat 553 is, since the second slide rheostat 553 is electrically connected with the first coil 342, the magnitude of the current flowing into the first coil 342 is in a reverse relation with the thickness of the steel plate, the first coil 342 generates a magnetic field force repulsive to the first magnetic block 341 after the current is flowing into the first coil 342, and further pushes the first magnetic block 341 to drive the first toggle block 33 to slide downwards on the first slide rheostat 32, so as to change the internal resistance value of the first slide rheostat 32, and since the first slide rheostat 32 is electrically connected with the second coil 444, the farther the first slide rheostat 32 slides downwards, the larger the current introduced into the second coil 444 is, after the current in the direction of the current introduced into the second coil 444 is changed continuously, the second coil 444 generates a magnetic field force which drives the second magnetic block 445 to rotate circumferentially around the iron core 443, so that the second magnetic block 445 drives the threaded block 446 to rotate synchronously under the action of the rotating sleeve 442, then the threaded block 446 drives the threaded rod 441 to move upwards through the matching of the internal threads and the upper threads of the threaded rod 441, and further drives the second scroll 42 to move downwards synchronously, and the speed of the downward movement of the second scroll 42 is in a reverse relation with the thickness of the steel plate.
Further, when the steel plate rolling operation is completed and the next steel plate is replaced, the worker presses the control switch 6, and the control switch 6 is electrically connected with the third coil 531, so that current is introduced into the third coil 531, magnetic field force attracting the magnetic force limiting block 534 is generated, and then the rotating wheel 543 is reset under the action of gravity.
