In the steel plate production process, it is a special equipment used to unwind the rolled steel coils from the storage or transportation state and continuously and smoothly feed them into the subsequent processing equipment. When uncoiling the steel coils, the hydraulic system provides power for the uncoiler.

[0016] A method for using a steel plate production uncoiling device, specifically comprising the following steps:

[0017] S1: After the steel coil is positioned on the surface of the winding roller, the one-way bearing in the alarm mechanism is adjusted to contact the surface of the steel coil. When the coil collapses, the one-way bearing is driven in the reverse direction by the return movement of the steel coil and the expansion of its diameter, thereby driving the contact wheel to drive in the reverse direction, causing the ejector rod to flip to a vertical position. Subsequently, the expansion of the steel coil diameter causes the longitudinal displacement, causing the ejector rod to squeeze the first touch switch, thereby generating an alarm.

[0018] S2: After the steel coil is positioned on the surface of the winding roller, the telescopic end of the hydraulic rod is adjusted to make the roller contact with the surface of the steel coil. When the steel coil collapses, the roller is squeezed by extending in the radial direction to move the roller toward the inside of the adjustment groove, thereby driving the touch rod to press the second touch switch, thereby driving the hydraulic rod to make the squeezing plate closely contact with the surface of the steel coil, and cooperate with the locking mechanism to control the continued collapse of the steel coil;

[0019] S3: After the steel coil is positioned on the surface of the winding roller, one end of the steel coil is passed through the locking mechanism. When the coil collapses, one end of the steel coil will produce a return displacement, and the steel plate will be clamped by two upper and lower clamping blocks, thereby generating a stopping force for the continued return of the steel coil.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention provides an alarm mechanism, which can flip the push rod to be vertically upward through the return movement generated when the steel coil collapses, and at the same time, use the radial expansion displacement generated when the steel coil collapses to push the push rod vertically upward, drive the first touch switch, start the alarm, realize the alarm of the coil collapse, and promptly remind the operator to shut down the uncoiler and stay away from the operator, thereby reducing the damage rate of mechanical parts, ensuring the personal safety of the operator, avoiding the occurrence of personal injury accidents, and improving the safety of operation.

[0022] 2. The present invention can monitor the collapse of the steel coil in real time by setting a clamping mechanism, and drive the extrusion plate to squeeze the surface of the steel coil through the hydraulic rod. In conjunction with the locking mechanism, the speed of the collapse can be effectively slowed down, giving the operator enough time to shut down the equipment and stay away from the equipment, thereby reducing the damage rate of mechanical parts, ensuring the personal safety of the operator, avoiding personal injury accidents, and improving the safety of operation.

[0023] 3.

[0036] As a further limitation of the alarm mechanism 2 of the present invention, the alarm mechanism 2 includes a positioning plate 201 fixedly connected to the top of the shell 11, an L-shaped rod 202 is slidably connected to one side of the positioning plate 201, a first receiving groove 203 and a second receiving groove 204 are provided at the bottom end of the L-shaped rod 202, a first light touch switch 205 is fixedly connected to the inner cavity of the first receiving groove 203, an alarm 206 is fixedly connected to the top of the shell 11, the first light touch switch 205 and the alarm 206 are electrically connected, an extension rod 207 is slidably connected to the inner cavity of the second receiving groove 204, a rotating rod 208 is fixedly connected to the bottom of the extension rod 207, a contact wheel 209 is rotatably connected to the surface of the rotating rod 208, a first torsion spring 210 is arranged between the contact wheel 209 and the rotating rod 208, and the two ends of the first torsion spring 210 are respectively fixed to the inner wall of the contact wheel 209 and the surface of the rotating rod 208 The surface of the tactile wheel 209 is fixedly connected, and a one-way bearing 225 is fixedly sleeved on the surface of the tactile wheel 209. A connecting rod 211 is fixedly connected to one end of the connecting rod 211, and a clamping rod 212 is fixedly connected to the surface of the clamping rod 212. A push rod 213 is fixedly connected, and the push rod 213 is used in conjunction with the first light touch switch 205. By setting the alarm mechanism 2, the push rod 213 can be flipped to a vertical position upward through the return movement generated when the steel coil collapses. At the same time, the radial expansion displacement generated when the steel coil collapses is used to push the push rod 213 vertically upward, drive the first light touch switch 205, and start the alarm 206 to realize the alarm of the collapse, and promptly remind the operator to shut down the uncoiler body 1 and keep away from the personnel, thereby reducing the damage rate of mechanical parts, ensuring the personal safety of the operator, avoiding the occurrence of personal injury accidents, and improving the safety of operation.

[0037] One end of the clamping rod 212 is fixedly connected to a first magnet 214, and a clamping slot 215 is provided on one side of the extension rod 207. The inner cavity of the clamping slot 215 is fixedly connected to a second magnet 216. The first magnet 214 and the second magnet 216 are used in conjunction with each other. By arranging the first magnet 214, the second magnet 216 and the clamping slot 215, when the one-way bearing 225 and the contact wheel 209 are driven by the return force of the steel coil, the contact wheel 209 is rotated, and the rotation of the contact wheel 209 drives the clamping rod 212 Flipping synchronously with the first magnet 214, when the first magnet 214 follows the card rod 212 to flip and embed into the inner cavity of the card slot 215, the contact wheel 209 stops rotating. At this time, the first magnet 214 and the second magnet 216 are magnetically attracted to each other. Even if the contact wheel 209 is subjected to excessive force and disconnected from the extension rod 207, the top rod 213 is still in a vertical upward state through the magnetic attraction of the first magnet 214 and the second magnet 216, thereby ensuring the stability of the vertical upward state of the top rod 213.

[0038] Two sliding grooves 217 are provided on the inner wall of the second receiving groove 204, and the two sliding grooves 217 are arranged opposite to each other. The inner cavity of the sliding groove 217 is fixedly connected with a guide rod 218, and the surface of the guide rod 218 is slidably connected with a guide block 219, which contacts the inner cavity of the sliding groove 217. The opposite sides of the two guide blocks 219 are respectively fixedly connected with the two sides of the extension rod 207, and the surface of the guide rod 218 is slidably sleeved with a first spring 220, one end of the first spring 220 is fixedly connected with the inner top wall of the sliding groove 217, and the other end of the first spring 220 is fixedly connected with the top of the guide block 219; through the coordinated use of the sliding groove 217, the guide rod 218, the guide block 219 and the first spring 220, the vertical guidance of the moving trajectory of the extension rod 207 is realized, the first spring 220 can realize the elastic adjustment of the vertical moving distance of the extension rod 207, and the reaction force of the first spring 220 can ensure that the one-way bearing 225 is always in close contact with the surface of the steel coil.

[0039] A moving groove 221 is provided on one side of the positioning plate 201. A threaded rod 222 is rotatably connected to the inner wall of the moving groove 221 through a bearing. One end of the threaded rod 222 is rotatably connected to the top of the housing 11. A moving block 223 is threadedly connected to the surface of the threaded rod 222. The moving block 223 is slidably connected to the inner cavity of the moving groove 221. One side of the moving block 223 is fixedly connected to one side of the L-shaped rod 202. A handle 224 is fixedly connected to the top of the threaded rod 222. Through the moving groove 221 and the threaded rod 2 22. The moving block 223 and the handle 224 are used in coordination. After the operator completes the placement of the steel coil, the operator turns the handle 224. The rotation of the handle 224 drives the threaded rod 222 to rotate. The rotation of the threaded rod 222 drives the moving block 223 to move vertically. The movement of the moving block 223 drives the L-shaped rod 202 to move vertically, thereby being able to adjust the height of the L-shaped rod 202 according to the thickness of the steel coil, so that the one-way bearing 225 on the surface of the contact wheel 209 fits tightly with the surface of the steel coil.

[0040] The specific implementation of this embodiment is as follows: after the operator has positioned the steel coil on the surface of the winding roller 12, the operator rotates the handle 224, and the rotation of the handle 224 drives the threaded rod 222 to rotate, and the rotation of the threaded rod 222 drives the moving block 223 to move vertically, and the movement of the moving block 223 drives the L-shaped rod 202 to move vertically, and the vertical movement of the L-shaped rod 202 drives the extension rod 207 to move, and the vertical movement of the extension rod 207 drives the rotating rod 208 to move vertically, and the vertical movement of the rotating rod 208 drives the contact wheel 209 to move vertically until the one-way bearing 225 on the surface of the contact wheel 209 is in close contact with the surface of the steel coil, so that the L-shaped rod 202 is moved vertically. 202 continues to move downward to compress the first spring 220. During compression, it is necessary to ensure that there is an appropriate distance between the top rod 213 and the first touch switch 205. When the coil collapses, the uncoiling end of the steel coil will produce a return displacement due to the expansion of the steel coil volume during the coil collapse. At this time, the one-way bearing 225 is driven. The one-way bearing 225 rotates forward to a rotatable state and rotates backward to a non-rotatable state. A rubber pad is provided on the fixed sleeve on the surface of the one-way bearing 225 to increase the friction between the one-way bearing 225 and the steel coil. The reversal of the one-way bearing 225 drives the reversal of the touch wheel 209. The reversal of the touch wheel 209 drives the connecting rod 211 and the clamping rod 212 on its surface. The first magnet 214 and the second magnet 216 are magnetically attracted to each other, thereby increasing the vertical stability of the top rod 213. At the same time, the expansion displacement of the steel coil during the collapse of the steel coil pushes the one-way bearing 225, the contact wheel 209, the connecting rod 211, the clamping rod 212, the top rod 213, the rotating rod 208, and the extension rod 207 to generate a vertical upward displacement in the inner cavity of the second receiving groove 204. The extension rod 207 guides the vertical movement trajectory of the extension rod 207 and the vertical movement trajectory of the extension rod 207 through the guide rod 218, the sliding groove 217, the guide block 219 and the first spring 220. The elastic adjustment of the moving distance, when the top rod 213 follows the extension rod 207 to move up to contact the first touch switch 205 in the first storage groove 203, the alarm 206 is driven. The alarm 206 is an audible and visual alarm. The audible and visual alarm is a safety alarm device, which alerts people to danger or emergency situations by emitting sound and light signals. This is a prior art and will not be described in detail. The audible and visual alarm of the alarm 206 reminds the operator of the occurrence of a collapse, so that the operator can shut down the equipment in time and stay away from the equipment. By setting the first torsion spring 210, the reaction force of the first torsion spring 210 can be used to reset the rotation angle of the touch wheel 209.

The present invention makes corresponding improvements to the technical problems mentioned in the background technology. A clamping mechanism 3 is provided on one side of the winding roller 12. The clamping mechanism 3 is used in conjunction with the alarm mechanism 2. The clamping mechanism 3 is used to squeeze the steel coil after it collapses.

[0042] As a further limitation of the clamping mechanism 3 of the present invention, the clamping mechanism 3 includes a support block 301 fixedly connected to the surface of the uncoiler body 1, a hydraulic rod 302 is fixedly connected to the top of the support block 301, and a squeeze plate 303 is fixedly connected to the telescopic end of the hydraulic rod 302, and three adjustment grooves 304 are provided on the surface of the squeeze plate 303, and two receiving grooves 305 are provided on the inner side of each adjustment groove 304, and the inner cavity of each receiving groove 305 is fixedly connected to a guide rod 306, and the surface of each guide rod 306 is slidably connected to a guide block 307, and the opposite sides of every two guide blocks 307 are commonly fixedly connected to a mounting plate 308, and the inner sides of the three mounting plates 308 are rotatably connected to rollers 30 9, wherein one side of the three guide blocks 307 is fixedly connected with a touch rod 310, and the inner sides of the corresponding three receiving grooves 305 are fixedly connected with a second touch switch 311, and the three second touch switches 311 are electrically connected to the hydraulic rod 302; by setting the clamping mechanism 3, the collapse of the steel coil can be monitored in real time, and the hydraulic rod 302 drives the squeezing plate 303 to squeeze the surface of the steel coil, and cooperates with the locking mechanism 4, which can effectively slow down the speed of the collapse, and buy enough time for the operator to shut down the equipment and stay away from the equipment, thereby reducing the damage rate of mechanical parts, ensuring the personal safety of the operator, avoiding the occurrence of personal injury accidents, and improving the safety of operation.

[0044] The specific implementation of this embodiment is as follows: after completing the positioning of the steel coil, the hydraulic rod 302 is started through the external power supply and controller, and the extension of the telescopic end of the hydraulic rod 302 drives the extrusion plate 303 to move toward the surface of the steel coil, and the movement of the extrusion plate 303 drives the roller 309 to move toward the surface of the steel coil until the roller 309 contacts the surface of the steel coil. A pressure sensor is provided on the surface of each mounting plate 308, and the pressure sensor is electrically connected to the hydraulic rod 302. When the roller 309 loses contact with the surface of the steel coil, the hydraulic rod 302 is controlled to continue to extend through the pressure sensor until the pressure sensor reaches a set value. The pressure sensor converts this pressure into a measurable electrical signal, and the converted electrical signal is transmitted to the external controller. The hydraulic rod is controlled by the external controller 302 is driven, thereby ensuring that the roller 309 is always in contact with the surface of the steel coil after the steel coil is unwound and becomes thinner. The roller 309 is rotatably installed through the mounting plate 308. When the steel coil collapses, the displacement caused by the expansion of the steel coil squeezes the roller 309, thereby squeezing the mounting plate 308. The mounting plate 308 is guided by the accommodating groove 305, the guide rod 306 and the guide block 307, which improves the stability of the mounting plate 308 when moving. The guide block 307 moves with the mounting plate 308, thereby driving the touch rod 310 to move until the touch rod 310 squeezes the second touch switch 311 to start the second touch switch 311, thereby driving the hydraulic rod 302 to extend, applying sufficient squeezing force to the surface of the steel coil, and slowing down the speed of the collapse.

[0046] As a further limitation of the locking mechanism 4 of the present invention, the locking mechanism 4 includes a support frame 401 fixedly connected to one side of the shell 11, and two locking blocks 402 are fixedly connected to the top of the support frame 401. The inner side of the locking block 402 is rotatably connected to two clamping blocks 403. The two clamping blocks 403 are arranged opposite to each other up and down. The inner walls of the two clamping blocks 403 are fixedly connected to a rotating rod 404, and the rotating rod 404 is rotatably connected to the inner wall of the locking block 402.

[0047] A fixed block 407 is fixedly connected to the surface of each rotating rod 404, and a limiting groove 408 is provided on the surface of the fixed block 407. A limiting strip 409 is fixedly connected to the inner side of each locking block 402, and the limiting strip 409 is used in conjunction with the limiting groove 408. By setting the fixed block 407, the limiting groove 408 and the limiting strip 409, when the rotating rod 404 follows the reversal of the clamping block 403, the fixed block 407 is driven to flip, and the limiting groove 408 is flipped to be embedded with the limiting strip 409. At this time, the cooperation between the limiting strip 409 and the limiting groove 408 can realize the limitation of the flipping angle of the fixed block 407, thereby realizing the limitation of the rotation angle of the rotating rod 404 and the clamping block 403, thereby increasing the stability of locking the unwinding end of the steel coil.

[0048] The specific implementation of this embodiment is as follows: after the steel coil is positioned on the surface of the winding roller 12, it passes through the inner cavity of the locking block 402 and passes between the two clamping blocks 403 arranged opposite to each other. Before the steel plate passes through, the two clamping blocks 403 are in a vertically opposite state through the cooperation of the second torsion spring 406 and the sleeve rod 405. The opposite surfaces of the two clamping blocks 403 are in close contact. When the unwinding end of the steel coil passes through the contact surfaces of the two clamping blocks 403, the two clamping blocks 403 are pushed so that the two clamping blocks 403 is flipped by the rotating rod 404, so as to ensure that the uncoiling end of the steel coil can smoothly pass through the two clamping blocks 403. The surface of the clamping block 403 is fixedly connected with a rubber anti-skid pad to increase the friction with the surface of the uncoiling end of the steel coil. When the coil collapses, the return force of the steel coil drives the uncoiling end of the steel coil to move back. When the uncoiling end moves back, it drives the two clamping blocks 403 to flip in the return direction. The distance between the two clamping blocks 403 gradually approaches, and the uncoiling end of the steel coil is tightly clamped, thereby slowing down the speed of the return displacement of the steel coil.

[0049] A method for using a steel plate production uncoiling device, specifically comprising the following steps:

[0050] S1: After the steel coil is positioned on the surface of the winding roller 12, the one-way bearing 225 in the alarm mechanism 2 is adjusted to contact the surface of the steel coil. When the coil collapses, the one-way bearing 225 is reversely driven by the return movement of the steel coil and the expansion of its diameter, thereby driving the contact wheel 209 to reversely drive the top rod 213, causing it to flip to a vertical position. Subsequently, the expansion of the diameter of the steel coil causes a longitudinal displacement, causing the top rod 213 to squeeze the first touch switch 205, thereby generating an alarm.

[0051] S2: After the steel coil is positioned on the surface of the winding roller 12, the telescopic end of the hydraulic rod 302 is adjusted to make the roller 309 contact with the surface of the steel coil. When the steel coil collapses, the roller 309 is squeezed by extending in the radial direction to move the roller 309 toward the inside of the adjustment groove 304, thereby driving the touch rod 310 to press the second touch switch 311, thereby driving the hydraulic rod 302 to make the squeezing plate 303 closely contact with the surface of the steel coil, and cooperate with the locking mechanism 4 to control the continuous collapse of the steel coil;

[0052] S3: After the steel coil is positioned on the surface of the winding roller 12, one end of the steel coil is passed through the locking mechanism 4 through an external device. When the coil collapses, one end of the steel coil will produce a return displacement, and the steel plate will be clamped by two upper and lower clamping blocks 403, thereby generating a restraining force on the continued return of the steel coil.
