Product Overview

The Jingshi Coil Processing Cut-to-Length Line is an advanced metal sheet production system developed for efficient and precise conversion of metal coils into flat sheets of specified lengths. By combining decoiling, straightening, precision feeding, shearing, conveying, and stacking functions into a single production line, the system provides a reliable and cost-effective solution for modern sheet metal processing operations.

In traditional sheet preparation processes, manufacturers often face challenges such as inconsistent flatness, inaccurate cutting dimensions, excessive labor requirements, and low production efficiency. The Jingshi cut-to-length line addresses these issues through automated processing and intelligent control technologies, enabling stable production performance, improved dimensional accuracy, and reduced operating costs.

The production line adopts servo-controlled feeding technology and precision leveling equipment to ensure excellent sheet flatness and cutting consistency. It can process various metal materials, including carbon steel, stainless steel, aluminum, galvanized steel, and copper alloys. Depending on production requirements, the system can be configured with different coil capacities, sheet thickness ranges, cutting lengths, and automation levels.

This equipment is widely used in industries requiring high-volume sheet preparation, including metal service centers, electrical equipment manufacturing, household appliance production, construction materials, transportation equipment, and general sheet metal fabrication industries.

Working Principle

The Jingshi Coil Processing Cut-to-Length Line operates through a coordinated sequence of automated processing stages. First, metal coils are loaded onto the loading station and transferred to the decoiler, where the material is continuously unwound under controlled operating conditions.

The strip material then enters the precision straightening section. Through repeated bending and correction by multiple leveling rollers, internal stresses, coil set effects, and surface irregularities are effectively removed. The processed material subsequently passes into the servo feeding section, where feeding speed and travel distance are precisely controlled according to preset production parameters.

A high-precision measuring system continuously monitors the material position and length during transportation. Once the programmed sheet length is reached, the shearing system automatically performs the cutting operation. The cut sheets are transferred through conveying devices and organized by the automatic stacking system.

The entire production process is managed by an intelligent control platform integrating PLC systems, servo controllers, sensors, and human-machine interfaces. Various safety mechanisms, including emergency stop circuits, overload protection, material monitoring, and fault alarm functions, ensure reliable and safe operation while maintaining high production efficiency and product consistency.
