Full-Auto Steel Clipping Machine

The durable Full-Auto Steel Clipping Machine is manufactured by Pulan, a professional manufacturer in China. Its clamping blades are designed with concave and convex points to enhance gripping force, ensuring a more secure connection that is less likely to loosen. The machine is suitable for filter elements with a height of 30–250mm and pleat height of 10–38mm, achieving a production capacity of 12 pieces per minute. Compared with traditional hot melt adhesive bonding methods, steel strip clipping provides a stronger sealing effect and effectively reduces the risk of filter joint leakage.

Equipment Introduction

The Full-Auto Steel Clipping Machine is an automated production machine that uses V-shaped steel strips to clamp and seal the joints at both ends of filter elements. The system consists of a material rack, forming roller assembly, steel strip feeding unit, steel strip clipping unit, cutting unit, filter element conveying mechanism, and filter joint sealing mechanism.

During operation, flat steel strips are gradually formed into a V-shape through multiple forming rollers. The formed steel strip is then automatically fed to the filter element joint, where the clamping blades with special surface patterns firmly press the steel strip onto the filter element and cut it simultaneously. This process creates a reliable mechanical seal and replaces conventional adhesive bonding methods.

Operating Principle & Production Workflow

The machine first converts flat steel strip into a V-shaped profile through multiple forming rollers. The formed strip is then transported to the filter element joint position. The clamping blades press the V-shaped steel strip tightly onto the filter element while cutting the strip at the same time, creating a strong and durable sealed connection.

Production Process

1. Steel Strip Loading: Install the steel strip coil onto the material tray and guide the strip through the flattening rollers and blocks for leveling.
2. V-Shape Forming: The leveled steel strip passes through forming rollers and is shaped into a V profile.
3. Strip Feeding: The formed steel strip moves through the feeding mechanism into the clipping position.
4. Filter Element Loading: Insert the filter element into the upper and lower guide slots, then transfer it to the pushing station through feeding rollers.
5. Positioning: The pushing cylinder moves the filter element into the correct clipping position.
6. Clipping & Cutting: The clamping cylinder presses the V-shaped strip onto the filter joint and completes cutting simultaneously.
7. Unloading: The rotating door mechanism opens downward, allowing the finished filter element to drop smoothly.
8. Automatic Cycling: The next filter element enters automatically for continuous production.

Key Benefits

1. V-Shaped Steel Strip Clipping Instead of Adhesive Bonding: The mechanical clipping method provides stronger fastening than traditional hot melt glue bonding and effectively prevents joint leakage.
2. Special Clamping Blade Design: The concave and convex blade surface increases gripping force, preventing the steel strip from loosening after clipping.
3. Fully Automatic Operation: Steel strip forming, feeding, clipping, cutting, returning, filter feeding, positioning, and unloading are completed automatically, achieving 12 pieces/minute production.
4. PLC-Controlled Stable Performance: The PLC control system ensures consistent operation, accurate movements, and reliable product quality.
5. Integrated Forming, Feeding, Clipping, and Cutting: Multiple forming rollers, pneumatic feeding, and synchronized clipping/cutting complete the entire process efficiently.
6. Wide Application Range with Easy Adjustment: Suitable for filter heights of 30–250mm, pleat heights of 10–38mm, and steel strip thicknesses of 0.25–0.3mm. Product specifications can be changed quickly through adjustment handwheels and scales.
7. Gear-Rack Rotating Discharge Mechanism: The rack-and-pinion structure provides accurate rotation control and ensures smooth filter element release.
8. CE Certified Safety Design: Equipped with emergency stop, safety guard interlock, and grounding protection systems.

Technical Specifications

Installation Requirements

1. Install the Full-Auto Steel Clipping Machine on a flat, clean, and well-ventilated floor away from high temperature and dust.
2. Maintain at least 1 meter clearance on both sides and rear, and 1.5 meters at the front.
3. Use a forklift with a capacity of more than 1 ton for transportation.
4. Secure the machine and adjust the level before operation.
5. Connect to a dedicated 380V/50Hz power supply with proper grounding.
6. Provide compressed air at 0.6MPa.
7. Check cables, emergency stop switch, and safety door before operation. The machine cannot start when the safety door is open.

Frequently Asked Questions

Q1: What should I do if the steel strip length after clipping is too long or too short?

A: Adjust the steel feeding length through the strip length adjustment handwheel. Turn clockwise to increase the feeding length and counterclockwise to reduce it. Adjust according to the feeding scale and pointer position.

Q2: Why is the steel strip clipped too high or too low on the filter element?

A: The distance between the feeding rollers, guide plates, door panel, and clipping blades may not match the filter pleat height. Loosen the locking nut, rotate the adjustment handle to change the clearance, and lock it after adjustment.

Q3: What should I check if the steel strip cannot be fed properly?

A: Check whether the air supply is connected correctly (0.6MPa), whether the feeding cylinder and pressing cylinder are operating normally, and whether the corresponding solenoid valves are functioning properly.

Q4: Why does the filter element fail to unload smoothly?

A: The rotation angle of the feeding door panel may be insufficient.

Adjust the gear-rack stroke to increase the opening angle and ensure smooth filter element discharge.
