2.5m Vertical Insulating Glass Washing Machine

Key Features

1. High-Efficiency Washing Section

3 pairs of soft nylon brushes (optional: 4 pairs) gently remove dust, grease, and particulate from both glass surfaces.

Brush pressure is adjustable to accommodate glass thickness from 3 mm to 19 mm.

Stainless steel washing chamber resists corrosion and ensures long service life.

2. High-Pressure Air Knife Drying

Multi-stage air knife system with adjustable wind speed delivers complete moisture removal.

Heating system optional for cold-climate operations, ensuring spot-free drying even at low ambient temperatures.

Blower motor with noise-reduction housing for quieter operation.

3. Water Circulation System

Multi-stage water filtration with recycling tank reduces water consumption and operating costs.

Automatic water level control and sediment drainage keep the system clean with minimal manual intervention.

4. PLC Touchscreen Control

7" / 10" color touchscreen with intuitive interface.

Digital display of conveyor speed, water temperature, air pressure, and brush status.

Fault alarm and self-diagnosis for quick troubleshooting.

5. Pneumatic Conveyor System

Wear-resistant rubber rollers driven by pneumatic cylinders provide stable, scratch-free glass transport.

Conveyor speed is inverter-controlled and adjustable from 0–12 m/min to match production line pace.

6. Safety & Protection

Emergency stop buttons at both entry and exit ends.

Photoelectric sensors detect glass position and automatically adjust conveyor speed.

Overload protection on all motors.

Technical Parameters

Line Configuration & Workflow

The Automatic Washing Drying Press Line for Insulated Glass is arranged as a straight-flow production line consisting of four interconnected stations. Glass sheets enter at the loading end and pass sequentially through each section:

• Loading and inspection section: Glass panes are placed manually or by loader onto the input conveyor. Optical sensors detect glass presence, dimensions, and coated surfaces before feeding into the washing zone.
• Washing and rinsing section: Rotating nylon brushes with adjustable pressure scrub both glass surfaces. Fresh water or recirculated water is sprayed through flat-jet nozzles, followed by a demineralized water rinse to prevent mineral residue.
• Drying section: Heated air is blown through air knives positioned above and below the glass path. The air knife gap adjusts to glass thickness automatically. A closed-loop heating system recirculates and reheats the air to maintain drying efficiency while managing energy consumption.
• Assembly and press section: The aluminum spacer frame, pre-filled with desiccant and coated with primary seal, is positioned on the glass pane. The second glass pane is aligned pneumatically. The servo-driven press brings the panes together at a controlled rate. Argon filling can be performed in this section through a probe inserted between the panes before final pressing.

Each line undergoes a full test run with actual glass before shipment, and a pre-delivery inspection report is provided. The standard warranty is one year on the main structure and components. Remote technical support, online program updates, and operation training are included. Spare parts are stocked and can be dispatched with regular freight shipments. On-site installation and commissioning can be arranged at additional cost.

FAQ

Q1: What kinds of insulated glass can this line produce?

A: It processes double glazed, triple glazed, Low-E coated, and laminated insulating glass units. The finished IGU thickness range is 10 to 48 mm, covering standard window, door, and curtain wall specifications.

Q2: Can the machine automatically identify coated glass?

A: Yes. Optical detection sensors at the washing section entry identify Low-E and other coated surfaces. The system can be set to alert the operator or pause the line if a pane is loaded with the coated side incorrectly oriented.

Q3: Is the drying effect completely water-free?

A: The closed-loop hot air circulation system combined with self-adapting air knives is designed to dry the glass surface and edges completely. The air knife gap adjusts to the glass thickness, and the recirculated air is continuously reheated to maintain consistent evaporation conditions.

Q4: Is daily maintenance complicated?

A: Key inspection points such as filters, brush rollers, and air knife nozzles are accessible through side panels and widened access doors. Routine tasks like filter cleaning and brush inspection can be performed without disassembling major sections. A maintenance schedule is provided in the operation manual.

Q5: Does it support long-term continuous operation?

A: The electrical and pneumatic components are selected for continuous industrial duty. The PLC, drives, motors, and sensors are sourced from major international suppliers. Under recommended maintenance intervals, the line is designed for 24-hour operation in high-volume insulating glass production.
