Full-automatic FFS Form-Fill-Seal Bag Packaging Machine with High Precision Weighing System

Production flow

Full-automatic FFS bag packaging machine adopts the integrated technology of form-fill-seal and realizes the automatic operation of weighing, bag making, filling and sealing, etc.

Equipment Composition

1. Film coil lifting mechanism is mainly to roll up the film, so as to facilitate the uncoiling for bag applicator.

2. Bag applicator is mainly to stretch the film into the packaging machine and temporarily keep the film.

3. Corner sealer is for splayed-shape sealing of the two sides of M-shaped bag.

4. Bag length adjuster is to adjust the corner sealing to the proper position when the set value of the bag length changes. In case of the need of adjustment, value can be set via the touch screen; then motor works and drives the adjusting wheel to move to realize the adjustment.

5. Bag feeder conveys uncut bag and sends bag length signal to PLC; when it starts to convey bag, the motor drives the roller to rotate at a high speed until the conveyed length reach a certain ratio of the set bag length, then PLC controls the motor to rotate at low speed and while reaching the set bag length, the motor stops and the conveying of one bag is completed.

6. Bottom sealer cuts out an empty bag as per the set bag length and heat-seals the bottom of the next bag. When the bag enters the bottom sealer and reaches the set bag length, air cylinder drives the clamping bar to grasp the bag; in the same time, it heat-seals the bottom and cut the bag. The distance between the seal and bag end is less than 10 mm.

7. Bag opener opens the mouth of the bag mouth to prepare for material filling. When an empty bag is transferred to this station, suction cups open the bag; then vacuum valve opens to partially release the cups; and after the angle bars clamping the bag mouth, the vacuum valve closes to completely release the suction cups.

8. Filling spout is an important functional unit in integrated automatic packaging machine. When the opened empty bag arrives at the filling position, motor drives the filling spout to descend via the driving rod and the flap opens to fill material into the bag. In the same time, dusts are sucked into the de-dusting system. After the completion of filling, the motor drives the filling spout to ascend via the driving rod and closes the flap.

9. Bag clamp is to cooperate with the filling spout at filling station to complete material filling. It clamps the opened bag and moves inboard while the filling spout descends and flap opens.

10. Bag mouth sealer is to seal the mouth of filled bags. When a filled bag is conveyed to the sealing station, the clamping bars match with the bag mouth sealer and the heating elements at the inner side power on and heat seal the bag mouth; when the heating finishes, clamping bars and sealer opens. The distance between the seal and bag end is less than 10 mm.

11. Bag mouth cooler is to cool the sealed bag mouth and improve the reliability. When the heat-sealed bag is transferred to the bag mouth cooler, air cylinder drives the cold air pipe to cool the heat-sealed part of the bag. After the bag mouth is cooled, the bag is released and cooling circle finishes. One bag will be cooled twice successively.

Functional features

1. Compact structure, high integration, floor space saving;

2. Continuous supply of large rolls of film to improve the speed of packaging and reduce the frequency of changing bag types and replenishing bags;

3. Length of bag changeable according to different materials to reduce packaging cost;

4. Thermal sealing technique adopted to improve sealing quality and product appearance.
