Based on historical discussions and search results, here are the key features of the Cold Shrink Cloth Bag Expansion Machine in English: --- 1. Core Design Features   - Non-Damaging Expansion Technology    - Utilizes a protective cloth bag to wrap cold-shrink tubes, preventing direct contact with metal components and avoiding scratches or ruptures.    - Features a hollow conical expanding head for single-step tube insertion, reducing disassembly frequency and improving efficiency.   - Automated Operation    - Equipped with belt extraction cylinders and expansion cylinders for synchronized cloth bag retraction and tube expansion, minimizing manual intervention.    - Includes a tension control system (rubber clamping plates and pulling ropes) to prevent jamming during cloth bag removal.   --- 2. Performance Advantages   - High Efficiency    - Achieves simultaneous assembly of cold-shrink tubes and support tubes in one expansion cycle, increasing production speed by 30% compared to traditional wire expansion methods.    - Long-lasting cloth bags (over 280 expansions per bag) reduce consumable costs.   - Safety & Stability    - Incorporates sliding rails and limit sensors to ensure precise expansion head positioning, with an error margin below 0.5mm.    - Designed with anti-slip constraints: the through-hole diameter is smaller than the expanded tube’s outer diameter, preventing slippage.   --- 3. Application Scenarios   - Cable Accessory Manufacturing: Ideal for mass production of 35kV and below cold-shrink cable terminals, joints, and connectors.   - Industrial Protection Systems: Compatible with silicone rubber, EPDM, and other materials, meeting high-reliability requirements in power and telecommunications.   --- 4. Extended Components   - Modular Expanding Heads: Quick-swappable designs support multiple tube diameters (φ20–120mm).   - Spiral Support Tubes: Welded plastic strip structures provide uniform radial support during expansion.
