Steel coil feeding and speed controlling device of full-automatic uncoiler

Abstract

The invention provides a steel coil feeding and speed controlling device of a full-automatic uncoiler, belonging to the technical field of the full-automatic uncoiler. The device overcomes the defect of loose coil or impact coil since the existing full-automatic uncoiler can not accurately control the feeding speed of a steel coil in real time. The steel coil feeding and speed controlling device of the full-automatic uncoiler comprises a rotating shaft provided with an installation section and a suspension arm section, wherein the installation section of the rotating shaft is arranged inside a base and is connected with a power mechanism for driving the rotating shaft to rotate along the positive direction and the opposite direction; and the suspension arm section of the rotating shaft is provided with a steel coil tensioning mechanism, and one side of the suspension arm section along the uncoiling direction of the steel coil is provided with an ultrasonic controller used for detecting the sagging degree of an uncoiled steel plate. Furthermore, the steel coil feeding and speed controlling device also comprises an electrical control system for controlling the power mechanism to drive the rotating shaft to rotate along the positive direction and the opposite direction according to the signals transmitted by the ultrasonic controller. The device can be used for automatically feeding the steel coil and controlling the feeding speed and the stretching force of the steel coil in real time, and can adjust when the steel coil has the phenomenon of loose coil or impact coil.

Description

technical field [0001] The invention belongs to the technical field of automatic uncoilers, and relates to a steel coil feeding and speed control device, in particular to a steel coil feeding and speed control device of an automatic uncoiler. Background technique [0002] In the sheet metal processing industry, large-scale rolling equipment is usually used for continuous pressing and forming of metal sheets. In order to facilitate production, improve efficiency and reduce labor intensity, the raw material sheets used are pre-wound into cylindrical steel coils, which are stored in special on the charging rack in order to keep it in a reasonably controlled state. The uncoiler is a kind of equipment that continuously or intermittently unfolds the cylindrical steel coil. At present, there are many forms of uncoilers. In terms of functions, there are mainly mechanical passive uncoilers, semi-automatic uncoilers, and fully automatic uncoilers. [0003] The fully automatic uncoil...

AI Technical Summary

Problems solved by technology

[0003] The fully automatic uncoiler in the fully automated production line can automatically feed the steel coil into the production line. The steel plate uncoiled from the uncoiler is suspended and sent to the main machine of the production line. Due to the weight of the steel plate itself, the suspended steel plate will sag. However, the existing fully automatic uncoiler cannot accurately control the feeding speed of the steel coil in real time, resulting in the problem of unwinding due to excessive sagging of the steel plate due to excessive uncoiling speed, or the problem of unwinding caused by the steel plate being straightened due to too slow uncoiling speed. In this way, it has a great impact on the uncoiling and leveling quality of the plate and the life of the equipment
