Working Process

1. Pre-place Empty Bags
Place 2~3 stacks of empty bags at the same time to provide bags for the packaging machine.

2.Take an Empty bag
The bag sucking mechanism sucks the bottom of the bag with negative pressure, while the roller-up type bag transmission structure flattens the bag mouth and transmits it to the bag opening station.

3.Open Empty bag
The bag opening mechanism simultaneously sucks the positive and negative sides of the bag mouth with negative pressure. The negative pressure sucks the bag mouth and lifts it, and then the “insert knives” structure located on both sides of the material discharge port is inserted into the bag mouth by shaft rotation and spread to both sides.

4.Supply Empty bag

Transfer the empty bag to the bag clamping mechanism by lifting up the knife arm to complete the bag supplying operation. The bag clamping mechanism clamps both sides of the bag to prevent dust from overflowing.

5.Material Filling
The bag clamping detection device ensures the reliability of the bag supplying. After the detection is completed, the PLC will give a signal to the automatic weighing unit, then the material in the weighing unit will be discharged into the packaging bag. During the filling process, perform bottom vibration operation. At the same time, through the external dust removal interface, the dust formed by the material is pumped away in the discharge process.

6.Holding bag and Stitching Sewing & Heat Sealing
After the material filling is completed, the bag mouth is clamped horizontally through the bag-holding conveying mechanism, then the bag is horizontally conveyed to the guide entry mechanism, and the bag is conveyed to the stitching sewing & heat sealing station for automatic stitching sewing or heat sealing.
