What is Full-Auto Hdaf Wire Mesh Rolling Machine?

Full-Auto Hdaf Wire Mesh Rolling Machine is an automatic machine designed for spiral rolling and forming of metal outer mesh for large air filters. The pulling mechanism drives the steel strip continuously forward. After flattening and mesh rolling forming, the machine automatically cuts the material according to the preset length.
The machine adopts touchscreen + PLC control and is equipped with 15 sets of molds (diameter specifications 13~35 corresponding to 130~500mm). Different specifications can be switched by replacing molds. The angle and cutter parameters can be adjusted according to the specification table. It is suitable for efficient mass production of large air filter outer mesh.

Equipment Application and Structure

Application

Spiral rolling and forming of large air filter outer mesh (steel strip).
Steel strip width: 54mm
Steel strip thickness: 0.4~0.6mm

Main Components:

Loading rack: Fixes the steel strip coil and adjusts the parallelism of the feeding inlet
Pulling mechanism: Feeding shaft (jog feeding / automatic feeding)
Flattening mechanism: Levels the steel strip
Mesh rolling mechanism: Main shaft, molds (15 specifications from 13-35), seam rollers, edge folding rollers
Cutting mechanism: Cutter (cylinder driven), measuring ruler frame (length adjustment)
Control system: Touchscreen (manual/automatic mode, automatic zero positioning, current speed display, cutter adjustment)
Auxiliary: Mold support rod, template groove, cutter rod stopper

Working Principle and Production Process

Basic Principle:

The steel strip is continuously fed by the pulling shaft and flattened by leveling rollers before entering the mesh rolling main shaft. The main shaft rotates and drives the steel strip to spiral around the mold. When the preset length is reached, the cutter automatically cuts the material to complete one mesh cylinder.

Production Process:

Loading: The steel strip coil is fixed on the loading rack. Adjust the feeding inlet parallel position and cut the steel strip end into an approximately 30° tapered angle.
Mold Installation: Select the corresponding mold according to the required diameter, fix it with countersunk bolts, and reinforce it through the mold support rod.
Parameter Setting: Select manual mode on the touchscreen, press "automatic zero positioning" to return the cutter to the original position; adjust the machine angle and cutter parameters according to the specification table.
Manual Feeding: Use jog feeding to slowly feed the steel strip into the mold and manually guide the strip to complete one winding cycle.
Automatic Operation: Switch to automatic mode and adjust the speed control knob (current speed approximately 10 rpm). The steel strip continuously rolls into mesh form.
Cutting: After the steel strip joint rotates one circle, manually stop the machine and press "manual cutting" to remove excess material. Then, in automatic mode, the steel strip will be automatically cut when it reaches the length set by the ruler frame.
Output: Remove the finished mesh cylinder.

Product Features

1. Pull-Type Continuous Feeding, High Efficiency
The pulling mechanism continuously feeds the steel strip and completes flattening, mesh rolling, and cutting in one process. The production capacity reaches 15~30m/min.
2. Wide Diameter Range (130~500mm), Fast Mold Change
Full-Auto Hdaf Wire Mesh Rolling Machine is equipped with 15 sets of molds (13~35 specifications). Different diameters can be switched by replacing molds. After installation, molds are reinforced by support rods, enabling quick changeover.
3. Adjustable Length and Accurate Cutting
The measuring ruler frame adjusts the cutting length (the length from the main shaft cutter to the mesh outlet is the required length). Cutter parameters can be fine-tuned according to the specification table to ensure smooth cutting edges.
4. Touchscreen + PLC Control, Easy Operation
Supports manual/automatic mode switching, one-button automatic zero positioning, real-time speed display, manual cutter control, and convenient parameter setting.
5. Specification Table Assistance, Reducing Trial Adjustment
The machine is supplied with a steel strip spiral mesh rolling specification table, listing the corresponding angle adjustment values and cutter adjustment values for different diameters, allowing quick parameter setup.
6. Smooth Outer Mesh Surface, No Secondary Processing Required
After mesh rolling, the outer mesh surface is flat and smooth, requiring no additional grinding or finishing, reducing production procedures.
7. Less Waste, Lower Cost
The spiral mesh rolling process provides high material utilization. The steel strip end only needs to be cut into a 30° tapered angle, reducing production waste.
8. Compact Structure and Easy Maintenance
Overall dimensions: 1650×1100×1600mm
Weight: 900kg
Regular maintenance only requires lubrication of the main shaft, gears, and chains, and cleaning iron chips from the cutter.

Technical Parameters

Installation Precautions

Install on a flat, clean, and well-ventilated site.
Keep a distance of ≥1 meter from surrounding walls (according to general standards).
Use a forklift for transportation, fix the machine, and adjust the level.
Power supply: 380V/50Hz, must be independently grounded.
Air supply pressure: 0.6MPa.
Check cables, emergency stop button, and protective cover before operation.
Before first operation, manually rotate the machine to confirm there is no jamming.

Frequently Asked Questions

Q1: What should I do if the mesh cylinder diameter is too large or too small?
A: If the diameter is too large, the gap between the two feeding shafts is usually too small. If the diameter is too small, the gap is usually too large. Adjust the feeding shaft gap first; if the problem remains, adjust the tightness of the seam roller.

Q2: What causes separation at the mesh cylinder seam?
A: The edge folding roller may be too loose, causing insufficient edge locking. Adjust the pressure of the outer edge folding roller to ensure the seam is firmly connected.

Q3: How to handle incorrect feeding or material jamming?
A: First check whether the steel strip end is cut into a 30° tapered angle and whether the feeding inlet is parallel with the steel strip. If jamming occurs, remove the inlet convex plate to clear the material, reinstall the plate, and resume operation.

Q4: What is the difference between mold installation for diameters below and above Φ200?
A: When producing mesh cylinders below Φ200 diameter, the stopper on the cutter rod needs to be removed. When producing diameters above Φ200, reinstall the stopper. Otherwise, it may affect cutting or mesh rolling performance.
