The DZFJ-M Single Shaft Automatic Roll Change Rewinding Machine is designed for automatic rewinding and roll change for flexible web materials. It combines automatic roll change, single-shaft rewinding, edge trimming, and online defect inspection to improve rewinding consistency while reducing material waste and operator workload. Compatible with woodfree paper, kraft paper, coated paper, PE-coated paper, silicone paper, aluminum foil, PVC, plastic film, adhesive tape, nonwoven, and insulation rolls. Widely used in paper product processing, printing and packaging, and flexible packaging production industries.

Core Functions and Features

Automatic Roll Change

The single-shaft automatic roll change mechanism automatically switches finished rolls during the rewinding process. This reduces downtime between rolls, minimizes manual intervention, and supports continuous converting production without stopping the line. Operators can focus on quality monitoring rather than manual roll handling.

Single-Shaft Rewinding

The single-shaft design provides straightforward and reliable rewinding operation for a wide range of flexible web materials. Consistent tension control ensures uniform roll tightness from core to outer layer, eliminating common problems such as telescoping, loose cores, and uneven winding.

Edge Trimming

Built-in edge trimming function produces clean, consistent finished roll edges. This ensures that downstream processes such as printing, laminating, and slitting receive properly trimmed rolls, reducing material waste and improving overall production quality.

Online Defect Inspection

The integrated online defect inspection system monitors the web during the rewinding process in real time. It detects web breaks, material defects, and other quality issues early, allowing operators to take corrective action before significant material waste occurs. This feature is particularly valuable for high-value materials such as aluminum foil and coated paper.

Continuous Production Support

The combination of automatic roll change and single-shaft rewinding enables continuous production with minimal interruptions. The machine supports 24-hour operation schedules, making it suitable for high-volume converting facilities that require maximum uptime and throughput.

Technical Overview

Applicable Materials

Paper Products

Woodfree paper, straw paper, coated paper, kraft paper, PE-coated paper, and silicone paper. The automatic roll change and edge trimming ensure consistent roll quality for downstream printing and packaging processes.

Films and Foils

Aluminum foil, PVC, and plastic film rolls. The online defect inspection system is particularly valuable for detecting tears and pinholes in thin film and foil materials during high-speed rewinding.

Tape and Nonwoven

Adhesive tape and nonwoven fabric rolls. The single-shaft rewinding with consistent tension control handles these materials without stretching, wrinkling, or telescoping, delivering uniform finished rolls.

Insulation and Composite Materials

Insulation materials and composite rolls used in specialized industrial applications. The machine's versatility and customizable configuration accommodate various material thicknesses and roll diameters.

Application Industries

Paper Product Processing

Rewinding and trimming of paper rolls for paper mills and paper processing facilities. The automatic roll change reduces labor costs and increases throughput for high-volume paper converting operations.

Printing and Packaging

Preparing rolls for printing presses and packaging lines. Clean edge trimming and consistent roll tightness ensure smooth feeding in downstream printing and converting equipment, reducing press downtime.

Flexible Packaging Production

Rewinding of composite films, aluminum foil, and plastic films for flexible packaging manufacturing. The defect inspection system catches material defects before they reach the packaging production line.

Nonwoven Converting

Rewinding and trimming of nonwoven fabric rolls for hygiene products, medical supplies, and industrial applications. The automatic roll change supports continuous nonwoven production lines.

Why Choose the DZFJ-M

Reduced Downtime

The automatic roll change mechanism eliminates manual roll handling between cycles, significantly reducing non-production downtime and increasing overall equipment effectiveness (OEE).

Versatile Material Compatibility

From paper and cardboard to films, foils, tapes, and nonwovens, the DZFJ-M handles a broad spectrum of flexible web materials without requiring extensive changeover or reconfiguration.

Quality Assurance

The combination of edge trimming, consistent tension control, and online defect inspection ensures that every finished roll meets quality standards before it moves to the next production stage.

Customizable Configuration

Working width, roll diameter, production speed, and optional control functions can be tailored to specific production requirements. Send your material sample and specifications to Sanhui Machinery for a customized solution and quotation.
