Heavy-Duty 25KG & 50KG Powder Filling Machines Bag Loading & Sealing System

• The single-station independent weighing system adopts servo motor arc gate control, which enables fast weighing and high precision.

The material is added to the weighing hopper by the feeding mechanism (pneumatic gate). After the controller receives the weight signal from the sensor, it controls according to the preset program value. At the beginning, rapid feeding (fast, medium and slow feeding at the same time) is performed. When the weight ≥ (target value - coarse measurement value), stop the fast acceleration signal output and enter the medium speed (medium acceleration and slow acceleration at the same time) feeding; when the weight ≥ (target value - fine measurement value), stop the medium speed Add signal output and enter slow speed (slow adding) feeding; when the weight ≥ (target value - overshoot value), stop slow adding signal output, the feeding door is completely closed, and fixed value weighing is completed. After the bag clamping signal is input, the weighing hopper discharge door automatically opens. When
the weight ≤ zero setting value, the weighing hopper discharge door automatically closes, and the material bag automatically releases and falls onto the conveyor belt, and is sent to the sewing machine. After sewing the bag, it enters the next process, and at the same time, the controller enters the next control cycle.

Touch screen, PLC, C3 level load cell, dual 6-bit high-precision weighing controller (sampling speed up to 128 times/second), and
frequency converter to ensure filling quality and accuracy

It is mainly composed of material inlet, feeding mechanism (gate), weighing hopper, bag clamping mechanism, frame, air suction
port, pneumatic system, sensor, control box, etc.
