Technical Field

[0002] The current production of silicon steel thin strip rewinding production lines all adopts the method of manually opening the steel coil lead. Manually opening the lead has high requirements for ambient light and surrounding vision conditions. Operators need to operate beside the machine on site. The equipment is easy to hit the steel coil during operation, and manual assistance is required to pull the lead when necessary. Especially when the thin strip is unrolled, it is easy to cause the strip to stack and wrinkle, which increases the operator's troubleshooting, increases the amount of waste cutting, and reduces the yield rate. This manual lead opening method has high labor load, low production efficiency, safety hazards, and is easy to cause secondary damage to the product. It is imperative to add functional equipment for automatic upper and lower opening of the lead. Therefore, a set of automatic upper and lower lead opening equipment is developed for the new silicon steel thin strip rewinding production line to completely replace manual operations. Previously, automatic unwinding technology was also applied in silicon steel annealing production lines, but it could only realize automatic upper unwinding operation, and there was no application performance that took into account the automatic upper and lower unwinding functions. The rewinding production lines all require upper and lower unwinding functions to meet the production needs of turning over incoming materials. As the thickness of silicon steel products becomes thinner and thinner, the thinnest thickness is less than 0.2mm, and the output accounts for an increasingly higher proportion, the demand for automatic upper and lower unwinding functions has become more urgent.
