As shown in fig. 3 and 4, the invention also discloses a method for fully automatically uncoiling a steel coil, which adopts the steel coil fully-automatic uncoiler 100, wherein an uncoiling scraper knife and a clamping roller of the steel coil fully-automatic uncoiler are arranged at an inlet of a pinch roller channel line 200 of the uncoiler, and the uncoiling process comprises the following steps:
step 1: the steel coil 300 with accurate positioning of the strip head is transported to the area of the uncoiler through the steel coil transportation trolley, the uncoiler winding drum 400 is sleeved, then the pressing roller 500 is placed in the steel coil outer ring, and the uncoiling in the uncoiling process is prevented. The steel coil head is positioned at the fixed position of the steel coil trolley in the previous process, and the diameter of the steel coil is measured in a laser ranging mode in the transportation process.
Step 2: and positioning the uncoiling initial position of the steel coil head according to the diameter D of the steel coil. When the steel coil strip head is coiled, the steel coil strip head is positioned in the direction of about 4 o' clock and half, and the uncoiling is inconvenient at the moment. Thus, before unwinding, the tape head needs to be adjusted to the unwinding position. The method comprises the following steps: when the outer diameter of the steel coil is larger than 1350mm, the winding drum of the uncoiler rotates reversely (namely clockwise in the figure) by 180 degrees, so that the tape head rotates clockwise from the position of about four and a half points to the position of about 11 and a half points during the coiling, namely the uncoiling initial position of the tape head. When the outer diameter of the steel coil is smaller than or equal to 1350mm, the winding drum of the uncoiler needs to be inverted by 200 degrees to reach the uncoiling initial position.
The initial position of opening a book of coil of strip head is located the below of deep bending roller 600 position, and deep bending roller 600 keeps its initial position throughout in the whole process of opening a book, does not participate in opening a book.
And step 3: starting uncoiling, wherein in an initial state, the scraper knife swinging oil cylinder 6 drives the uncoiling scraper knife to rotate 90 degrees anticlockwise, then the support frame driving oil cylinder 8 drives the swinging support frame 10 to swing towards the direction of the steel coil, namely the uncoiling assembly and the clamping assembly swing in along with swinging, so that the knife tip of the uncoiling scraper knife faces the strip head; the uncoiler drum rotates forward (clockwise in the figure), so that the belt head is pressed against the upper uncoiling shovel blade, and the belt head penetrates through a gap between the uncoiling shovel blade and the clamping drum and extends forwards for a certain distance, and the uncoiler drum stops rotating.
In step 3, the angle from the start to the stop of the uncoiler drum is n, wherein n is 136000/D, and D is the diameter of the steel coil. In the actual production process, setting is carried out according to the actual situation. If D is 2000mm, n is 68 °; when D is 1500mm, n is 91 °.
And 4, step 4: the support frame drives the piston rod of the oil cylinder 8 to retract, so that the swing support frame 10 swings back to reset. Then the scraper knife swinging oil cylinder 6 drives the uncoiling scraper knife to rotate clockwise by 90 degrees, after the strip head is lifted, the clamping lifting oil cylinder 9 drives the clamping roller 2 to press down to press against the strip steel; then the scraper knife lifting oil cylinder 7 and the clamping lifting oil cylinder 9 synchronously act to drive the uncoiling scraper knife and the clamping roller to integrally ascend.
And 5: and the uncoiler starts forward rotation again to enable the strip head to move towards the inlet of the pinch roll channel line and enter the pinch roll channel, the pinch roll clamps the strip head, the uncoiling assembly resets, the clamping assembly resets, and the automatic uncoiling is completed.
