Description

Technical Parameters

The Coil Feeding Device for Roll Forming Machine is used as the front-end supporting equipment for cold roll forming lines, including roofing sheet machines, steel section forming machines, and light steel keel machines. It supports and fixes the steel coil, supplies strip material continuously to the main forming machine, and helps keep the strip aligned before it enters the rollers. It is suitable for color steel coils, galvanized steel strips, and other metal coil materials used in roof panel, wall panel, purlin, keel, and building accessory production.

Product Advantages

1. Labor Cost Reduction – The Coil Feeding Device for Roll Forming Machine can support and fix 3–5 ton steel coils for continuous unwinding, reducing repeated manual coil positioning and allowing operators to focus on PLC setting, inspection, and finished profile handling.

2. Increased Productivity – The feeding rack keeps the coil fixed and supplies strip steel continuously to the forming section. For production using 3–5 ton coils, it reduces interruptions caused by loose coils, manual repositioning, or uneven feeding.

3. Material Savings – The feeding unit can be customized according to the raw material thickness and width, so the strip enters the roll forming machine through a matched guide path. With edge correction before forming, it helps reduce off-center feeding, start-up adjustment waste, and profile defects caused by strip deviation.

4.Improved Machine Stability-Automatic edge correction keeps the strip centered before it enters the rollers, reducing side pulling, surface scratching, and profile offset. This helps maintain stable feeding for galvanized steel, color steel, and strip steel used in cold roll forming lines.

Main Applications

Coil Processing: Roll forming production lines designed to handle the material uncoiling function for manufactured products.
Production lines for the manufacturing of purlins and steel structural components.
Auxiliary production lines designed to complement forming machine lines for steel studs and tracks used in partition wall systems (utilizing raw materials for studs and ceiling panels).
Any general-purpose coil processing production lines requiring stable uncoiling and feeding capabilities.

Quality Control

Coil Data Review

Confirm coil width, thickness, inner diameter, outer diameter, weight, material, and spring-back before selecting accessories.

Centerline Check

Align the feeder center height and strip path with the downstream forming machine.

Control Test

Test inverter speed adjustment, forward and reverse movement, sensor signal, and emergency-stop linkage.

Accessory Test

Check brake action, pressure arm movement, feeding trolley travel, and mechanical locking when these parts are supplied.

Maintenance Record

Mark chain, bearing, lubrication, sensor, and electrical inspection points for the 3-month routine check.

FAQ

Q: What is the main difference between using a Coil Feeding Device and manual coil loading?

A: Manual loading is labor‑intensive, slow, and prone to alignment errors. A Coil Feeding Device For Roll Forming Machine automates the entire process: it holds the coil securely, feeds it at a controlled speed, and corrects lateral wandering automatically. This results in higher throughput, consistent product quality, and significant labor savings.

Q: How often does the Coil Feeding Device require maintenance?

A: Routine maintenance is minimal. We recommend inspecting the drive chains, bearings, and sensors every three months, and lubricating moving parts as needed. The device is built for durability, and any worn components can be replaced quickly to avoid prolonged downtime.

Q: What information is needed for the Coil Feeding Device for Roll Forming Machine?

A: Provide coil width, thickness, inner diameter, outer diameter, weight, material, line speed, feed direction, and loading method.

Q: When should the pressure arm or feeding trolley be added?

A: Use these parts when coil spring-back, coil weight, loading height, or workshop crane conditions require controlled loading and release.
