Fulling Automatic Insulating Glass Molecular Sieve Filling Machine

Key Features

The Fulling Automatic Insulating Glass Molecular Sieve Filling Machine provides controlled filling of molecular sieve into aluminum spacer profiles for insulated glass fabrication.

• Control system: A touchscreen combined with a PLC allows the operator to set and adjust filling parameters, including drilling depth, fill time, and seal cycle. Program storage supports recall for different spacer profiles.
• Spacer compatibility: The machine processes aluminum spacers from 6 mm to 30 mm in width. Molecular sieve granules with a diameter between 0.5 and 0.8 mm are gravity-fed through the filling head.
• Frame capacity: Maximum frame dimensions are 2000 × 2000 mm, covering the common range required in architectural insulating glass lines.
• Power and air supply: The unit runs on a 220V / 50Hz single-phase supply and draws 1.0 kW. A stable working air pressure of 0.6 MPa is required for the pneumatic drill and sealing mechanisms.
• Automatic material replenishment: A level sensor in the desiccant hopper monitors the remaining sieve material. When the level drops below a preset point, the system either alerts the operator or triggers an external refill unit, depending on the configuration.

Working Principle

The Fulling Automatic Insulating Glass Molecular Sieve Filling Machine operates by first drilling a small hole into the aluminum spacer bar at the programmed position. A filling nozzle then injects a measured amount of molecular sieve desiccant into the spacer cavity. After filling, the same station or a dedicated sealing unit applies a seal to the hole, preventing moisture ingress and keeping the desiccant contained. The sequence is controlled by the PLC, which coordinates the drilling head, fill timer, and sealing action based on the spacer width and frame size entered on the touchscreen. An optical or capacitive sensor in the hopper monitors the desiccant level, and the machine can be connected to an external replenishment system to maintain supply during extended runs.

Key Components

• Desiccant hopper and feeder: A sealed stainless steel hopper holds the molecular sieve material. An agitator inside prevents bridging, and a metering screw or gate controls the amount delivered to the filling nozzle.
• Drilling unit: A pneumatic or electric drill motor drives a carbide drill bit sized to match the required hole diameter for the spacer profile. Drill depth is adjustable and set through the PLC.
• Filling head: Interchangeable nozzles match different spacer widths. A quick-release mechanism allows nozzle changes between production batches without tools.
• Sealing mechanism: The sealing station applies a pre-cut adhesive plug or a hot-melt seal over the drilled hole. The sealing time and pressure are programmable.
• Control panel: A color touchscreen with multi-language support displays real-time production data, alarm conditions, and maintenance reminders. The PLC stores up to 100 parameter sets for different spacer profiles.
• Frame transport system: Powered rollers move the assembled spacer frame into position. Adjustable guides center frames up to 2000×2000 mm, and pneumatic clamps hold the frame steady during drilling and filling.

Technical Specifications

FAQ

Q1: What is the main function of the Fulling Automatic Insulating Glass Molecular Sieve Filling Machine?

A: It drills holes into aluminum spacer bars, fills them with molecular sieve desiccant, and seals the holes automatically. This process removes residual moisture from the air cavity inside the insulating glass unit, which helps prevent internal fogging over time.

Q2: What size of glass frames can this machine handle?

A: The machine processes frames up to 2000 mm × 2000 mm. Aluminum spacer widths between 6 mm and 30 mm are accepted by the adjustable guides and quick-change filling nozzles.

Q3: Does the machine require manual intervention for refilling the desiccant?

A: The hopper is monitored automatically. When the desiccant level falls below a set point, the system can activate an alarm or trigger an automatic refill cycle if connected to an external supply system, minimizing interruptions.

Q4: What are the power and air pressure requirements for installation?

A: It requires a 220V / 50Hz single-phase supply (1.0 kW total power) and a stable compressed air supply at 0.6 MPa for the pneumatic components.

Q5: How does the machine ensure the desiccant stays inside the spacer?

A: After the filling nozzle retracts, a sealing mechanism immediately applies a seal over the drilled hole. This prevents the desiccant from leaking out and blocks ambient moisture from entering the spacer before assembly into the IGU.

Q6: Is the operation interface user-friendly?

A: The touchscreen provides access to all cycle parameters, production counters, and alarm logs. Parameter sets for different spacer profiles can be saved and recalled, reducing setup time when switching between orders.
