Core Equipment of Slitting Line: Belt Bridle Tension Unit for Metal Processing
Aug 03, 2026
The belt bridle tension unit is a specialized core equipment designed for precise tension control during the winding process in metal sheet and plate processing production lines. It is widely applied in longitudinal slitting lines for metal coils including stainless steel, galvanized steel, color-coated steel, and aluminum plates. Its core function is to provide stable and controllable reverse tension for the winding process, effectively preventing quality issues such as coil loosening and surface scratches.
Core Working Principle
Relying on a specially customized belt (with differentiated friction coefficients between the inner and outer layers) and working in coordination with steel sliders, the unit generates stable reverse tension through friction resistance. Meanwhile, it is equipped with a hydraulic cylinder pressure regulation system to achieve precise and dynamic control of tension, ensuring that the tension output fully aligns with production requirements.
Key Structural Advantages
Dual-station Intelligent Switching Design
Integrating two stations for belt tensioning and felt tensioning, it supports quick rotary switching. This design flexibly adapts to the processing of plates with different surface precision requirements, significantly enhancing equipment compatibility and production efficiency.
Efficient Circulating Cooling System
The annular belt runs on idlers equipped with a circulating cooling device. Continuous heat dissipation prevents overheating caused by long-term continuous operation, ensuring production stability and extending the service life of the equipment.
Non-destructive Surface Protection Mechanism
Adopting a synchronous operation design between the belt and the plate without relative sliding, it completely eliminates friction between components. This perfectly protects materials with high surface quality requirements, such as aluminum plates and color-coated steel, avoiding scratches during processing.
Typical Application Scenarios
Focused on precision metal strip longitudinal slitting production lines, the unit is precisely compatible with the front-end process of winders. It covers the processing needs of various metal coils, including stainless steel, silicon steel sheets, and high-end automotive plates, serving as a critical core device to guarantee winding quality.
Breakthrough in Core Value
Previously, this equipment was exclusively imported from Japan, characterized by high procurement costs and lengthy delivery cycles, which severely constrained the production rhythm of downstream enterprises. Shanghai Hoyo Industries Co., Ltd, drawing on years of R&D, manufacturing, and on-site application experience in Slitting Line machines, has successfully independently developed a high-performance equivalent product. This achievement enables the domestic substitution of core equipment, providing the industry with a reliable, self-controllable solution featuring better cost-effectiveness and shorter delivery cycles.
