200mm Inner Diameter CNC Automatic Spiral Paper Tube Core Winding Making Machine: A Technical Overview

This advanced equipment is specifically engineered for high-precision production of paper tube cores with a 200mm inner diameter, catering to industrial demands for consistency, efficiency, and automation. It integrates CNC (Computer Numerical Control) technology with spiral winding mechanics, making it a core asset in sectors like packaging, textiles, printing, and cable manufacturing.

Core Specifications & Technical Configuration

At its heart, the machine features a CNC control system that enables real-time parameter adjustment—including winding speed (15-30 tubes per hour), paper layer count (3-12 layers), and glue application volume—with an accuracy of ±0.1mm for inner diameter tolerance. It accommodates raw materials such as kraft paper, recycled paper, and specialty composite paper (width: 50-200mm, thickness: 0.1-0.3mm). Key components include an automatic paper feeding unit (with tension control to prevent paper creasing), a spiral winding head (equipped with wear-resistant alloy rollers), a precision cutting module (for tube length customization: 300-2000mm), and a PLC-based safety system (with emergency stop and fault alarm functions).

Automated Workflow: From Raw Material to Finished Core

The production process is fully automated, minimizing human intervention. First, the CNC system receives pre-set parameters (e.g., inner diameter, tube length, layer count). The automatic feeder then unwinds and tensions the paper, which is coated with eco-friendly hot-melt glue via a metered application system. Next, the spiral winding head rotates the paper around a 200mm diameter mandrel, overlapping layers to form a dense, rigid tube core. During winding, a laser diameter sensor monitors the inner diameter in real time, sending feedback to the CNC system for instant adjustments. Once the tube reaches the target length, the automatic cutter trims it smoothly, and the finished core is conveyed to a collection bin—completing a continuous, error-free cycle.

Performance Advantages

1. High Precision: CNC control ensures uniform wall thickness (1.5-8mm adjustable) and consistent inner diameter, reducing product rejection rates to below 1%.

2. Efficiency: Automated feeding, winding, and cutting cut labor costs by 60% compared to semi-automatic machines, while 24/7 continuous operation boosts throughput.

3. Flexibility: Quick parameter modification allows switching between tube core specifications (e.g., different lengths or layer counts) in 5-10 minutes, adapting to small-batch or mass production needs.

4. Sustainability: It uses recyclable paper materials and low-VOC glue, aligning with global environmental standards, and its energy-efficient motor reduces power consumption by 15% vs. traditional models.

Application Scenarios

This machine produces 200mm inner diameter tube cores that serve as essential components:

• Packaging: For winding plastic films, aluminum foils, or adhesive tapes;

• Textiles: As yarn or fabric winding cores;

• Printing: For rolls of printing paper or labels;

• Cables: As protective cores for electrical cables during storage and transportation.

Industry Value

In an era of smart manufacturing, this machine bridges the gap between manual inefficiency and high-precision demand. Its automation and reliability help manufacturers scale production, improve product quality, and reduce operational costs—making it a pivotal tool for businesses aiming to enhance competitiveness in the global paper tube core market.
