[0002] Steel coils, also known as rolled steel, are formed into a rolled shape through hot pressing and cold pressing for convenient storage and transportation. During the production and processing of steel coils, as raw materials, steel coils are usually placed at the end of the production line, and the unwinding device drives the steel coils to rotate to realize the feeding of the steel coils, facilitating subsequent processing of the steel coils.

[0003] According to the patent with the patent number CN218193688U, an automatic feeding system for slitting steel coils is disclosed, including a material trolley, a pressure head mechanism, a material taking mechanism, a front swing bridge and a rear swing bridge. The loading trolley is arranged in front of the uncoiler and is used to transport the steel coil to the uncoiler; the pressure head mechanism is arranged between the uncoiler and the pinch roller device and is above the uncoiler; the material taking mechanism is arranged at the discharging end of the uncoiler.

[0004] The above solution can shorten the threading time and improve work efficiency during implementation. However, during the implementation of the above solution, it is difficult to adjust the diameter of the unwinding roller. When feeding steel coils with different diameters, it is often necessary to replace the unwinding roller with a model adapted to it, and the operation is relatively troublesome, greatly reducing the applicability of the device. Therefore, we provide an automatic high-speed feeding system for steel coils with PLC control to solve the above problems. Content of the Utility Model

[0026] The embodiment of the present utility model provides a steel coil automatic high-speed feeding system with PLC control.

[0027] Please refer to Figure 1 , which includes a feeding platform 1. A fixed frame 6 is fixedly connected to the top surface of the feeding platform 1. A universal wheel with a brake pad is installed on the bottom surface of the feeding platform 1, which is convenient for the staff to move and fix the device. The fixed frame 6 provides stable support for the feeding operation of the feeding conveyor belt 7, enabling the device to maintain stability during the feeding process.

[0028] Inside the fixing bracket 6, a feeding conveyor belt 7 is fixedly installed. Outside the fixing bracket 6, a PLC main control box 8 is fixedly installed. The feeding conveyor belt 7 and the PLC main control box 8 are both prior arts and will not be elaborated too much in this application. The feeding conveyor belt 7 can drive the steel coil to move through rotational friction, facilitating subsequent processing operations on the steel coil. Inside the PLC main control box 8, a PLC circuit board is installed, facilitating the staff to control the operation of the device through the PLC main control box 8.

[0029] Please refer to Figure 1 , Figure 2 and Figure 3 , on the top surface of the feeding platform 1, a support protection plate 2 is fixedly connected. Inside the wall of the support protection plate 2, a support sleeve 4 is rotatably connected. The support sleeve 4 is fixedly connected to the main unwinding plate 301. Outside the feeding platform 1, a servo motor is installed. The rotation speed of the servo motor and the winding speed of the feeding conveyor belt 7 are in a relatively stable state. Starting the servo motor can drive the support sleeve 4 to rotate, and the rotation of the support sleeve 4 can drive the main unwinding plate 301 to rotate, so that the steel coil roller 5 rotates and releases the steel coil inside, facilitating the feeding operation of the feeding conveyor belt 7 on the steel coil.

[0030] Please refer to again Figure 1 , inside the support protection plate 2, a steel coil roller 5 is provided. The steel coil roller 5 is sleeved outside the unwinding mechanism 3. The steel coil roller 5 is convenient for winding the steel coil, avoiding the random placement of the steel coil during production and affecting the use of the production site. Different calibers of the steel coil roller 5 will be selected according to the use of the steel coil. The unwinding mechanism 3 can be adjusted according to the caliber of the steel coil roller 5, enabling the unwinding mechanism 3 to maintain stable unwinding of the steel coil roller 5.

[0031] Please refer to Figure 3 , outside the support protection plate 2, an unwinding mechanism 3 with an adjustable caliber is provided. The unwinding mechanism 3 includes a main unwinding plate 301. Inside the main unwinding plate 301, a transmission rod 308 is rotatably connected. The end of the transmission rod 308 is fixedly connected to the rotation adjustment plate 302. When the transmission rod 308 rotates to drive the rotation adjustment plate 302 to rotate, it will not affect the stability of the main unwinding plate 301. At this time, the rotation adjustment plate 302 will rotate on the surface of the main unwinding plate 301, providing power for subsequent adjustment of the position of the unwinding support plate 305.

[0032] A micro-motor 309 is installed inside the support sleeve 4. The transmission rod 308 is located inside the support sleeve 4 and is fixedly connected to the output rotating shaft of the micro-motor 309. Both the micro-motor 309 and the servo motor are prior arts, and will not be elaborated in this application. Ventilation nets can be opened on the outside of the support sleeve 4 according to actual needs to prevent the micro-motor 309 from generating a high temperature during operation and affecting its own performance. When the micro-motor 309 starts, it can drive the transmission rod 308 to rotate, and when the transmission rod 308 rotates, it can drive the rotation adjustment plate 302 to rotate.

[0033] Please refer to Figure 3 and Figure 4 , the rotation adjustment plate 302 is rotatably connected to the outer surface of the main unwinding plate 301. A group of circumferentially arrayed adjustment sliding grooves 303 are opened inside the main unwinding plate 301. The radius of the main unwinding plate 301 is the same as that of the rotation adjustment plate 302. When the rotation adjustment plate 302 rotates, the position of the arc-shaped sliding groove 307 will change, forcing the limit sliding rod 306 to slide inside the arc-shaped sliding groove 307. When the limit sliding rod 306 slides, it can drive the adjustment slider 304 to slide inside the adjustment sliding groove 303, thereby changing the position of the unwinding support plate 305 and achieving the purpose of adjusting the diameter of the unwinding mechanism 3.

[0034] An adjustment slider 304 is slidably connected inside each adjustment sliding groove 303. When the adjustment slider 304 slides inside the adjustment sliding groove 303, the position of the unwinding support plate 305 can be changed, thereby adjusting the diameter of the unwinding mechanism 3 and enabling the unwinding mechanism 3 to stably support the steel coil roll 5 according to the actual diameter of the steel coil roll 5, avoiding the problem that the staff needs to replace the unwinding mechanism 3 every time different steel coil rolls 5 are used for feeding operations.

[0035] An unwinding support plate 305 is fixedly connected to the end of each adjustment slider 304. A layer of rubber pad is installed on the top surface of the unwinding support plate 305, which can not only increase the friction between the unwinding support plate 305 and the steel coil roll 5, enabling the unwinding support plate 305 to stably support the steel coil roll 5, but also play a certain buffering effect to prevent the unwinding support plate 305 from damaging the inner wall of the steel coil roll 5 during the process of supporting the steel coil roll 5.

[0036] A limiting slide bar 306 is fixedly connected to the outer surface of each adjusting slider 304. An arc-shaped chute 307 is provided on the outer surface of the rotating adjusting plate 302. Each limiting slide bar 306 is slidably connected to the corresponding arc-shaped chute 307. The arc-shaped chute 307 has a certain curvature. When the rotating adjusting plate 302 does not rotate, the arc-shaped chute 307 supports and limits the limiting slide bar 306, enabling the limiting slide bar 306 to be stably positioned in the arc-shaped chute 307, thereby keeping the unwinding support plate 305 stably supporting the steel coil roller 5. A limiting piece is installed at one end of the limiting slide bar 306 located outside the arc-shaped chute 307. By providing the adjusting slider 304 and the limiting piece, the limiting slide bar 306 can stably slide inside the arc-shaped chute 307, preventing the limiting slide bar 306 from shifting.

[0037] Working principle: When the staff wants to feed the steel coil, first adjust the diameter of the unwinding mechanism 3 according to the diameter of the steel coil roller 5, that is, first start the micro motor 309. The start of the micro motor 309 drives the transmission rod 308 to rotate. The transmission rod 308 drives the rotating adjusting plate 302 to rotate on the surface of the main unwinding plate 301. The rotation of the rotating adjusting plate 302 forces the limiting slide bar 306 to slide inside the arc-shaped chute 307. The sliding of the limiting slide bar 306 drives the adjusting slider 304 to slide inside the adjusting chute 303, thereby changing the relative position of the unwinding support plate 305, enabling the unwinding mechanism 3 to be adapted to the diameter of the steel coil roller 5. Then, hang the steel coil roller 5 on the unwinding support plate 305, pull the steel coil into the feeding conveyor belt 7, and finally control the feeding conveyor belt 7 to feed the steel coil through the PLC main control box 8.
