The working principle of the multi-head combination scale

1. The hoist feeds through the feeding plate, so that the material is concentrated on the main vibration plate, and then through the vibration of the main vibration plate, the material is evenly distributed on the main vibration plate to the line vibration plate.

2. When the material in the feeding tray is not or not enough to be detected by the material level photoelectric detector, it will send a signal to the main board, and then send a feeding signal to the elevator through the main board to feed the material.

3. The linear vibration machine vibrates, and the material is sent to each buffer hopper through the amplitude and the feeding time of the linear vibration.

4. The stepper motor works, open the buffer bucket and send the material in the bucket to the weighing bucket. When the weighing bucket participating in the combination is discharged or when the material in the weighing bucket is not enough, the material in the buffer bucket will automatically flow into weighing bucket

5. In the weighing bucket, the weight signal is generated by the sensor, processed by the AD module and turned into a digital signal and transmitted to the main board of the Haichuan intelligent control device through the data bus

6. The CPU on the main board reads and records the weight of each weighing bucket, and then selects the combination weighing bucket closest to the target weight through calculation, analysis, combination, and screening, and sends out that the combination scale has weighed the material and is ready to put it. ready signal for the feed.

7. When the CPU receives the allowable discharge signal from the packaging machine, the CPU sends a command to start the driver to drive the stepper motor to open the selected weighing bucket and unload the material into the chute into the collection hopper. If there is no collection hopper, directly Enter the packaging machine, and send a discharge signal to the packaging machine that the material has been discharged.

8. After the weighing hopper is discharged, the buffer hopper will replenish, weigh and combine the weighing hopper in time to prepare for the next feeding.

Main Features of Multi-Head Weigher Packaging Machine

1. Fast weighing speed---10 head scales can reach 70 bags/minute, 14 head scales can reach 120 bags/minute

2. The dynamic weighing accuracy is accurate----±0.1~2.0g

3. High degree of automation----integrate with elevator and packaging machine to automatically complete quantitative packaging system.
