Description
TECHNICAL FIELD
[0001] The present application relates to the field of silicon steel strip coil feeding, in particular to a silicon steel strip adjustable feeding device. BACKGROUND
[0002] The silicon steel strip is the core raw material of the electromagnetic element core of the motor, transformer, reactor and the like, which is produced, stored and transported in a roll shape. The silicon steel strip coil feeding device, as the connecting equipment of raw material storage and processing, is the key to solving the efficient, safe and lossless transfer and positioning of the roll-shaped raw material, and is the key component of the related production line. However, the traditional feeding rack adopts the suspension mode of the crane, and the silicon steel strip coil is usually heavy. When aligning, the silicon steel strip coil often swings on the lifting rope due to inertia when moving, and then the edge of the silicon steel strip coil is easily collided with the rack, so that the edge of the silicon steel strip coil is damaged after impact. The large weight of the large coil silicon steel strip coil also causes the insertion rod used to insert it to deform slightly when placed on the rack. The silicon steel strip coil deforms due to gravity at its own lower end because the bottom is suspended. When the silicon steel strip coil is fed, the lower end of the silicon steel strip coil rotates to the upper end, and the upper end rotates to the lower end, so that the silicon steel strip coil periodically deforms. This will cause the deformation to become larger and larger, and finally even cause the silicon steel strip coil to collapse or fall off, which is dangerous to the on-site personnel.

[0036] Working principle: As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, this adjustable feeding device for silicon steel strip first places the silicon steel strip roll onto the support platform 306 using a crane. The buffer pad 309 at the upper end of the side plate 308 cushions the roll and prevents damage from collisions. The hydraulic rod 304 is activated to move the support platform 305 upwards until it slides to the top of the slide groove 307. Then, the first motor 302 is activated to rotate the first lead screw 303, causing the slide platform 301 to move the silicon steel strip roll to the target position. The hydraulic rod 304 lifts the roll to a height where its center coincides with the center of the second lead screw 403. The roll then moves and nests on the outside of the support plate 408. At this point, the second motor 402 is activated. 2. The second lead screw 403 rotates on the surface of the material rack 401. When the second lead screw 403 rotates, it can drive the moving sleeve 405 to move. When the moving sleeve 405 moves, it is constrained by the second guide rod 4012 and the rotating arm 407, so that the support steel plate 408 is spread out in all directions, thereby fixing the silicon steel strip coil and finally achieving a stable feeding operation. This avoids damage to the silicon steel strip coil caused by direct feeding by the crane. At the same time, when the silicon steel strip coil is unloaded, it is supported by the support platform 306 and the side plate 308 to prevent the silicon steel strip coil from being suspended at the bottom, which would cause uneven stress and localized large gravity, resulting in periodic deformation. This plays a crucial role in ensuring product quality and the safety of operators. When the hydraulic rod 304 is activated, the movable support rod 603 moves upward, thereby driving the first rotating roller 605 to rotate along the first central axis 606, which in turn causes the second rotating roller 607 to rotate along the second central axis 608. While the second rotating roller 607 is rotating, it drives the rotating rod 601 to rotate along the contact point with the support platform 306 through the push groove 609. This ultimately achieves the protective effect on both sides of the silicon steel strip coil, preventing the silicon steel strip coil from sliding significantly during movement and causing it to fall off the support platform 306.
