The processing flow of molecular sieve filling

1. Molecular sieve filling machine aluminum bar positioning and compression

The aluminum bar positioning and pressing device consist of a pressing and positioning component, a square tube bracket, and a rear panel; the pressing and positioning component consists of a transverse pressing device and a longitudinal pressing device and is connected to the hollow glass molecular sieve filling device through the square tube bracket and the rear panel. Installed on the machine.

When the foot switch is turned on, the transverse compression cylinder works to push the transverse compression block and push the aluminum bar to the transverse positioning plate. After reaching the designated molecular sieve filling position, the transverse positioning is completed; the longitudinal compression cylinder pushes the V-shaped compression block to the horizontal positioning plate. The aluminum strip is pressed longitudinally, and the longitudinal pressing is stopped after the aluminum strip spacer is pushed to the position of the pressing block.

2. Molecular sieve filling machine aluminum strip drilling

The aluminum strip drilling device consists of a fixed connecting block, a connecting plate, a guide mechanism, a pneumatic drilling device, and a pneumatic drilling device positioning mechanism.

The PLC receives signals to control the solenoid valve to turn on and off the air in the cylinder. The cylinder pushes the screw movement to drive the drilling device forward and backward. At the same time, the pneumatic motor drives the drill bit to rotate, and the two drill bits feed to complete the drilling work.

3. Molecular sieve filling machine desiccant filling

The feeding device of the molecular sieve filling machine consists of a material box, a material box cover, a vacuum pump, a sensor, a cover plate, a feeder, a feeding pipe, a heater, etc.

The molecular sieve filling machine uses dual-control discharging to fill the molecular sieve. There is a connected blowing hole at the discharging port. During filling, the PLC controls the solenoid valve to blow air into the two discharging ports to speed up the filling speed of the molecular sieve.

At the same time, a sensor is installed in the upper, middle, and lower parts of the molecular sieve material box. The sensor detects the amount of molecular sieve in the material box, and uses a vacuum pump to evacuate the material box to generate negative pressure inside the charging box to realize the automatic replenishment function.

4. Molecular sieve filling machine butyl extruder sealing 

The butyl extruder sealing device consists of a hot mold, a hot mold bracket, a baffle, a connecting lever, a rubber bucket, a tie rod, a cylinder, a cylinder bracket, a resistance wire, and a thermocouple sensor.

The resistance wire and thermocouple sensor are heated in the hot mold and PLC is used to control the butyl extruder blocking temperature; the glue-pushing device uses a cylinder to push glue, and PLC is used to control the butyl extruder pushing pressure, which is conducive to controlling the size of the glue pushing pressure and avoids The butyl extruder pushing pressure is too high or too low.

By adjusting the filling time to adjust the filling volume, the two filling heads could set the filling time separately.
It can be filled with large-particle molecular sieves, which need to be customized with LIJIANG Glass; it can be filled with large-particle molecular sieves with a diameter of 1.0mm-1.5mm. Generally speaking, the particle range of molecular sieves is generally 0.5mm-0.9mm in diameter; the particles of small-particle molecular sieves, which the range is generally 1.0mm-1.5mm, 2.0mm-2.5mm, 2.5mm-3.0mm in diameter.
Start-up operation process

Check whether there is no debris in the filling barrel of the molecular sieve filling machine, the parameters meet the processing requirements, and the emergency stop switch is normal, then turn on the air source and power supply; open the compressed air main valve (the pressure is set to 6Bar), and press Control On to open Control the power supply, and the control power prompts to confirm and cancel the alarm; the operator holds the aluminum bar frame spacer frame, puts the aluminum bar frame on the receiving hook of the filling machine, steps on the switch pedal, the aluminum bar frame is tightened and fixed in position, and then in the aluminum bar frame Drill holes on both sides and fill with molecular sieve.


1. It is strictly prohibited to approach the screening area during the production process;
2. Push the butyl glue to seal, and the butyl glue should be heated to about 60°C (about 15 minutes);
3. Adjust the filling mode according to the size of the aluminum frame;
4. Working operator should wear protective eyewear when operating to prevent molecular sieves from falling into their eyes.
