Center Tube Rolling Machine

As a professional manufacturer in China, Pulan would like to provide you high quality Center Tube Rolling Machine. Controlled by a PLC program, it features touchscreen operation, digital diameter setting, and automatic scrap collection.

What is a Center Tube Rolling Machine?

A Center Tube Rolling Machine is an automated machine that uses the three-roller rolling principle to roll steel sheets or mesh sheets into cylindrical shapes. The machine consists of a decoiler, feeding rollers, rolling rollers, driving roller, pressing roller, reducer, and motor. With PLC program control, material feeding and rolling operations are synchronized. The product diameter can be set through the touchscreen, making it suitable for mass production of large air filter protective meshes and housings.

Applications and Machine Structure

Applications: Rolling processing of inner and outer protective meshes of air filter elements and air filter assembly housings, with a rolling height of ≤800mm.

Main Components:

· Decoiler: Holds the steel strip coil

· Feeding Rollers: Feed the material into the rolling area

· Rolling Unit: Driving roller and pressing roller (three-roller rolling principle)

· Reducer and Motor: Drive the rolling operation

· Control System: PLC + touchscreen, digital diameter setting

· Scrap Collection Device: Automatically collects waste materials

Working Principle and Production Process

Working Principle: 

Three-roller rolling principle: The material is fed by the feeding rollers and passes between the driving roller and pressing roller, where it is gradually bent into a cylindrical shape with the preset diameter.

Production Process:

1. Material Loading: Place the steel sheet or mesh sheet on the decoiler and adjust the stopper bar for positioning.

2. Parameter Setting: Enter product diameter, speed, and other parameters through the touchscreen.

3. Feeding: The material enters the rolling unit through the feeding rollers.

4. Rolling: The driving roller and pressing roller work together to roll the material into a cylindrical shape.

5. Discharging: Remove the finished rolled product after completion.

6. Scrap Collection: Edge waste is automatically collected by the scrap winding system.

Product Features

1. Wide Adjustable Diameter Range (Φ80-Φ350mm): Digital setting through the touchscreen makes adjustment quick and convenient.

2. Large Rolling Height (≤800mm): Suitable for processing large air filter protective meshes and housings.

3. PLC Program Control for Stable Operation: Feeding and rolling actions are precisely coordinated.

4. Three-Roller Rolling Principle for High Precision: Ensures smooth edges and good roundness of rolled products.

5. Compact Structure and Small Footprint: Overall dimensions are 1075×590×950mm, with a weight of 350kg.

6. Automatic Scrap Winding: Automatically collects edge waste to keep the working area clean.

7. Easy Operation and Maintenance: Touchscreen interface; only regular lubrication of gears and chains is required.

8. CE Certified, Export Quality: Multiple models have obtained CE certification.

Technical Parameters

Installation Precautions

1. Install the machine on a flat, clean, and well-ventilated site away from high temperatures and dust.

2. Keep a distance of ≥1 meter from walls on both sides and ≥1.5 meters at the front and rear.

3. Use a forklift with a capacity of more than 2 tons for transportation.

4. Fix the machine securely and adjust the level.

5. Connect to a 380V/50Hz power supply with independent grounding.

6. Check the cables, emergency stop button, and protective covers before operation.

Frequently Asked Questions

Q1: How is the rolling diameter adjusted?

A: Enter the required diameter value directly through the touchscreen (Φ80-Φ350mm). The PLC automatically controls the rolling rollers without manual adjustment.

Q2: What should I do if the material deviates during operation?

A: Check whether the feeding roller gap is uniform and whether the stopper bar is perpendicular to the feeding rollers. Adjust the stopper bar position to ensure even gaps on both sides of the material.

Q3: How can uneven edges of rolled products be solved?

A: This is usually caused by uneven gaps between the rolling rollers. Adjust the gaps at both ends of the rolling rollers to ensure consistent pressure between the upper and lower rollers.

Q4: What materials are suitable for this machine?

A: It is suitable for steel sheets and mesh sheets with a thickness of 0.3-1.2mm, mainly used for rolling inner/outer air filter protective meshes and assembly housings.
