[0002] The stainless steel pipe uncoiler is a device used to unwind and flatten the coiled stainless steel strip. It is mainly composed of a coiling device, a flattening device, a transmission device and a control system. The coiling device of the stainless steel pipe uncoiler is driven by a clutch and a motor to feed the coiled stainless steel strip into the flattening device. The flattening device adopts a roller structure, and the strip is gradually flattened through the rotation and pressure of multiple sets of rollers. The transmission device connects the coiling device and the flattening device through a transmission shaft and a chain to coordinate their operation. At the same time, the transmission device can also adjust the conveying speed of the stainless steel strip to meet different production needs. The control system is the core part of the stainless steel pipe uncoiler. It realizes automatic control of the uncoiler through electrical control and PLC programming.
