OPEN-MOUTH BAGGER
Product Description
An open-mouth bagger is a type of packaging machine that automatically fills and seals pre-made, open-mouth bags. The bags can be made of various materials such as paper, plastic, or woven polypropylene, and are suitable for a range of products including powders, granules, and pellets. In an open-mouth bagging system, a device holds each bag open, and the product is dispensed into the bag. Once the bag filling is complete, it is sealed, typically by heat sealing, stitching, or gluing to prevent any spillage or contamination. Open-mouth bagging systems are widely used in industries such as agriculture, food processing, chemicals, and construction to streamline packaging processes and increase efficiency.
Operation Principle
1. Pre-place Empty Bags: Place 2~3 stacks of empty bags at the same time to provide bags for the packer.
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 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 heat sealing (Sewing) station for automatic heat sealing (Sewing).
