Automatic Potato Weighing Bag Packing Machine are designed for dosing of agricultural products (potatoes, onion, garlic, apply etc) into knitted sleeves, box pallets, bags or cases. The material shall be cleaned and sorted out for the operation to be smooth and trouble free. The minimum size of fruits is 20mm.the maximum size of fruits is 120mm.the average effective volume of the hopper in which a dose is weighed is 70 dm3 (this corresponds to 50 kg of potatoes of size of ca.70 to 90 mm). The weight of a dose can be adjusted by 0.01kg in the range of 5 to 50kg.
The device can work as a last stage of an after-harvest assorting line, or it can work alone. One person is sufficient for its operation.
Working Process of Automatic Potato Weighing Bag Packing Machine
The pressure sensor sends the signal to the hopper to indicate the product weight. The electrical control unit receives data from the pressure sensor, then it will automatically calculate and output the information, so as to control the weighing process. The belt operates based on the target weight, coarse filling, medium filling and fine filling.
The sequence is coarse filling–medium filling–fine filling, so that the target weight is reached. When in the coarse filling, the wider belt is in a high speed, while in the medium filling, it will in a medium speed. Then coming to the target weight, the wider belt will stop. On the process of coarse filling and medium filling, the narrow belt keeps running slowly, while on fine filling, it will fill the products one by one to stop until reaching the target weight.
Feature of Automatic Potato Weighing Bag Packing Machine
- Two conveyor belt is installed on the machine frame. Each conveyor belt is driven separately, and the data can be adjusted individually. The 0.3m belt is controlled by a double operation speed electric reducer so that the belt can convey the products into the hopper. The 0.1m belt is by low-speed electric reducer. After the 0.3M belt is stopped, it will get an accurate measurement of the target weight.
- The hopper is installed in the bottom frame by a pressure sensor. There is a discharging door in the hopper, which is controlled by two cylinders for discharging and closure.
