It has become a development trend in the papermaking machinery industry to use AC drive instead of DC drive for high-speed detection rewinders. The paper roll rolled by the reeling machine is relatively soft, the inside may be damaged or broken, the edges on both sides are not neat, and the width of the paper cannot be directly used in paper processing or printing machines. The finished paper rolls with certain specifications and certain tightness requirements can only be shipped from the roll machine after trimming, slitting, splicing, and rerolling on the paper roll core.

The rewinding process mainly completes three tasks: firstly, cutting off the raw edges of the base paper; secondly, cutting the whole base paper into several widths that meet the user's specifications; thirdly, controlling the roll diameter of the finished paper roll to make it meet the factory specifications .
The high-speed inspection and rewinder is a new generation of rewinding inspection machine developed on the basis of digesting and absorbing advanced models from Europe and Japan, combining the characteristics of domestic raw materials, the operator's human body curve and habits, and using advanced three-dimensional design technology. The whole machine is optimized Coordinating the configuration of machine, electricity, light and gas, and adopting the latest foreign drive and control technology, it realizes the perfect unity of ease of operation, stability and high efficiency, and is widely used in post-printing product inspection and rewinding in the flexible packaging industry.
