AI Technical Summary
In the existing packaging equipment, materials are prone to falling out of the bag opening during the bagging process, especially when there is a lot of material, and the condition of the material inside the bag cannot be guaranteed.
The system employs a racetrack-shaped conveyor line and a feeding and bagging mechanism, including a material feeding mechanism and a bag opening buffer mechanism. The cooperation between the material feeding rod and the bag opening plate ensures the consistency of bag opening, and the aluminum foil bag clamping fixture and the top-supporting mechanism prevent materials from falling during the bagging process.
It achieves uniform opening of the packaging bag, ensuring stable filling of materials inside the bag, preventing materials from falling out, and improving the reliability and efficiency of bagging.
