The support plate 14 is configured to cooperate with the core shaft 3. The column 13 and the second hydraulic arm 10 provide stable support for one end of the core shaft 3, making the force on the core shaft 3 more reasonable.
[0016] Based on the above scheme, a limiting groove 15 is opened at the bottom of one end of the arc-shaped groove 12. A spring 16 is installed in the limiting groove 15. The top of the spring 16 is fixed to the base 17. The base 17 is slidably connected to the limiting groove 15, and the base 17 is matched with the column 13.

[0021] Working principle: The cold-rolled steel coil to be uncoiled is inserted into the mandrel 3, usually by forklift. Then, the second hydraulic arm 903 is activated, extending to provide temporary support for the end of the mandrel 3 using the pallet 11. The column 13 is then slid down to the base 17. The second hydraulic arm 903 is then slowly retracted, disengaging the pallet 11 from the end of the mandrel 3 and bringing the pallet 2 14 into contact with the end of the mandrel 3, pressing the column 13 downwards. The base 17 slides downwards, compressing the spring 16. When the second hydraulic arm 903 is fully retracted, the external safety pin is inserted into the safety through hole 18 and the safety groove 19, activating the first hydraulic rod 7. The first hydraulic rod 7 extends, causing the guide block 6 and support block 5 to slide. The support block 5 continuously presses against the inner wall of the cold-rolled steel coil. During this process, relative sliding occurs, and then the first hydraulic arm 802 is activated, extending it. The electric drive roller 803 presses against the outer side of the cold-rolled coil, and the electric drive roller 803 is activated. Simultaneously, the first hydraulic rod 7 retracts, and the support block 5 is stored in the trapezoidal groove 4. Then, the second hydraulic rod 903 is activated, adjusting the position of the guide plate 902 so that the bottom of the guide plate 902 is in contact with the end of the cold-rolled coil. Under the elastic force of the cold-rolled coil, the end slightly tilts up and contacts the guide plate 902. During the operation of the electric drive roller 803, the cold-rolled coil rotates continuously, and the cold-rolled sheet moves continuously along the guide plate 902 to the next process. During the uncoiling process, there is no manual close-range guidance of the cold-rolled sheet end. Compared with manual assistance in uncoiling and guiding the end of the cold-rolled coil, this device is safer and more reliable, reduces the safety risk to personnel, and improves the safety factor.
