A sliding groove is arranged between the clamping plate 504 and the clamping bracket 503, and the clamping bracket 503 is an L-shaped structure. The clamping plate 504 can be lifted and lowered on the clamping bracket 503 through the clamping cylinder 502, and the coil mounting plate 2 can be moved left and right on the workbench 9 through the electric guide rail 7, and a coil motor is arranged on the other side of the coil mounting plate 2, and the output end of the coil motor is fixedly connected to the coil mounting shaft 4.
[0028] By adopting the above technical solution, the coil can be unfolded after being installed on the coil installation shaft 4. When unfolding, since the coil is an arc-shaped structure, the coil moves along the workbench 9 toward the side close to the uncoiler body 1 and reaches the position of the coil traction mechanism 5. When the end of the coil is located between the traction plate 501 and the clamping plate 504, the clamping cylinder 502 on the clamping plate 504 is started, and the clamping cylinder 502 pushes the clamping plate 504 to move downward. After clamping the coil, the traction motor 507 is started, and the traction motor 507 drives the traction screw 506 to rotate. At this time, the traction screw 506 can drive the sliding block 505 to move, so that the traction plate 501 moves toward the side close to the uncoiler body 1, and the coil is pulled backward to the feed bin position. There is no need to manually pull the coil until the coil enters the feed bin.
[0029] Specifically, Figure 2As shown, the coil clamping mechanism 3 includes a servo motor 301 arranged inside the coil mounting shaft 4, and the power output end of the servo motor 301 is connected to the transmission shaft 302, and two groups of first bevel gears 303 are fixedly connected to the outside of the transmission shaft 302, and second bevel gears 304 are arranged around the two groups of first bevel gears 303, and a transmission screw 305 is fixedly connected to the middle of the second bevel gear 304, and a screw sleeve 306 is installed on the outside of the transmission screw 305 through a screw nut, and a clamping plate 307 with an arc structure is arranged at the end of the screw sleeve 306, the screw sleeve 306 passes through the coil mounting shaft 4 and is fixedly connected to the clamping plate 307, and two groups of screw sleeves 306 are arranged on the surface of a group of clamping plates 307.
[0030] By adopting the above technical solution, after the coil is sleeved on the outside of the coil clamping mechanism 3, the servo motor 301 is started, and the servo motor 301 drives the transmission shaft 302 to rotate. The transmission shaft 302 simultaneously drives the two sets of first bevel gears 303 to rotate, and the first bevel gear 303 drives the second bevel gear 304 to rotate. At this time, the second bevel gear 304 drives the transmission screw 305 to rotate. Under the action of the screw nut, the screw sleeve 306 moves on the transmission screw 305, thereby adjusting the position of the clamping plate 307, so that the clamping plate 307 is against the inside of the coil, and the coil is clamped by the inside of the coil, and the coil motor can drive the coil installation shaft 4 to rotate, thereby realizing the unfolding of the coil.
[0031] Working principle: The position of the coil mounting plate 2 is adjusted according to the width of the coil. The coil mounting plate 2 moves on the workbench 9 through the electric guide rail 7, so that when the coil is unfolded, any end of the coil can enter between the traction plate 501 and the clamping plate 504. The coil is sleeved on the coil mounting shaft 4, and the servo motor 301 is started. The servo motor 301 drives the transmission shaft 302 to rotate, and at the same time drives the two sets of first bevel gears 303 to rotate, and drives the transmission screw 305 to rotate through the second bevel gear 304. Under the action of the screw nut, the position of the clamping plate 307 is adjusted so that the clamping plate 307 is against the inside of the coil, and the coil is clamped by the inside of the coil, and the coil motor can drive the coil mounting shaft 4 to rotate, thereby realizing the coil. The material unfolding work, when unfolding, due to the arc-shaped structure of the coil, the coil moves along the direction of the workbench 9 to the side close to the uncoiler body 1, and reaches the position of the coil traction mechanism 5. After the end of the coil is located at the traction plate 501 and the clamping plate 504, the clamping cylinder 502 on the clamping plate 504 is started, and the clamping cylinder 502 pushes the clamping plate 504 to move downward. After clamping the coil, the traction motor 507 drives the traction screw 506 to rotate. At this time, the traction plate 501 moves to the side close to the uncoiler body 1, and the coil is pulled backward to the feed bin position. There is no need to manually pull the coil until the coil enters the feed bin. The coil enters the feed roller 8 and the leveling roller to process the coil.
