Description

Technical Field

[0001] This invention relates to a strip steel, specifically, to a device for automatically opening the top and bottom of thin silicon steel strips. Background Technology

[0002] Currently, silicon steel thin strip recoiling production lines all rely on manual operation to open the coil heads. Manual opening requires precise ambient lighting and a clear field of vision, necessitates operators being present at the machine, and the equipment is prone to hitting the coil. Furthermore, manual assistance is sometimes required to pull the coil head, especially when uncoiling thin strips, which can easily cause stacking and wrinkling, increasing operator workload, scrap volume, and reducing yield. This manual opening method is labor-intensive, inefficient, poses safety hazards, and can easily cause secondary damage to the product. Therefore, adding automated upper and lower opening equipment is essential. This paper proposes developing an automated upper and lower opening device for new silicon steel thin strip recoiling production lines to completely replace manual operation. Previously, automatic uncoiling technology was also used in silicon steel annealing production lines, but it could only achieve automatic upper uncoiling operation and had no application performance that combined automatic upper and lower uncoiling functions. Recoiling production lines all require upper and lower uncoiling functions to meet the needs of turning incoming materials. As the thickness of silicon steel products becomes thinner and thinner, with the thinnest thickness being <0.2mm, and the output proportion is becoming higher and higher, the demand for automatic upper and lower uncoiling functions is becoming more urgent.

[0025] Example 2

[0026] This invention relates to the working process of an automatic top and bottom opening device for silicon steel thin strip:

[0027] In operation, the automatic strip-opening guide roller device 1 of the present invention opens the anti-wrinkle roller 11 from the offline position to the working position, and then swings to contact the steel coil 8, flattening the strip head during the strip-opening process.

The swing and extension positions of the magnetic belt are automatically calculated and controlled according to the diameter of the steel coil, so that a smooth threading angle is formed between the magnetic belt and the steel coil. The unit controls the steel coil to reverse. When the strip head detection element detects the strip head of the steel coil, the unit automatically calculates the distance between the current position of the strip head and the position that is attracted to the magnetic belt, and automatically controls the steel coil to stop rotating. The strip head detection element on the belt conveyor feeds back the strip head attraction signal, the unit controls the steel coil to rotate forward, and the belt conveyor runs in the same direction, so that the strip head is transported along the belt conveyor to the subsequent equipment, completing the automatic strip-opening operation.
