AI Technical Summary

Technical Problem

Traditional roll rewinding devices for roll materials have problems such as air trapped in the rolls, which cannot be expelled, resulting in loose rolls, core slippage, and end face ripples. In addition, the single correction mechanism is prone to causing roll material deviation, especially when running at high speed or when the winding diameter changes greatly, the pressure roller cannot automatically adapt.

Method used

It adopts a linkage technology of dual correction, dual pressure rollers, slip shaft and active pressure roller, combined with correction probe, tension control system and take-up air expansion shaft to achieve stable exhaust and dynamic correction of the rolled material. The material path is optimized by the middle elliptical flange, rubber-coated pressure roller is used to avoid scratches, and crank structure is used to adjust the pressure roller angle.

Benefits of technology

It achieves efficient and stable rewinding of roll materials, improves rewinding quality and process stability, and is suitable for high-speed operation and scenarios with large changes in winding diameter. It avoids problems such as loose winding, air trapping and misalignment of roll materials, and is suitable for high-requirement roll materials such as tape, aluminum foil and non-woven fabric.

Abstract

This utility model relates to the field of rewinding processing devices, and discloses a device suitable for rewinding roll materials, including a first winding device and a second winding device. The first and second winding devices are respectively disposed at both ends of the equipment base, and are used to receive and rewind the roll material respectively. A main feed roller is disposed in the middle position between the first and second winding devices, and is used to pull the roll material forward along the transmission path. A first correction probe and a second correction probe are located before and after the main feed roller, respectively disposed on the unloading side and the winding side, and are used to detect the edge position of the roll material and provide feedback correction signals. This utility model, through the active bonding function of the winding pressure roller, can effectively eliminate trapped air during the rewinding process, improve winding tightness and product yield, and is particularly suitable for processing materials such as tape, aluminum foil, and non-woven fabrics that require high roll density.
