The working principle of multihead weigher

The work of a multihead weigher is mainly composed of the following eight parts:

1. The hoist feeds the material through the feeding pan to concentrate the materials on the main vibrating pan, and then through the vibration of the main vibrating pan, the materials are evenly distributed on the main vibrating pan to the linear vibrating pan

2. When the material in the feeding tray is not or not enough to be detected by the material level photodetector, it sends a signal to the main board, and then sends a feeding signal to the hoist through the main board to feed material

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

4. The stepping motor works, open the buffer hopper and send the material in the hopper to the weighing hopper. When the weighing hopper participating in the combination discharges or when the material in the weighing hopper is insufficient, the material in the buffer hopper will automatically flow into the weighing hopper. Weighing bucket

5. In the weighing hopper, the material generates a weight signal through the sensor, which is processed by the AD module to become a digital signal and transmitted to the main board of the intelligent control device through the data bus

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

7. When the CPU receives the discharging permission signal from the packaging machine, the CPU sends a command to start the driver to drive the stepper motor to open the selected weighing hopper and unload the material into the chute into the collecting hopper. If there is no collecting hopper, it will directly Enter the packaging machine, and send a discharge signal to the packaging machine that it 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 discharge.

Main features of multihead weigher

*** Fast weighing speed----10 bucket multi-head weigher can reach 70 bags/minute, 14-bucket multi-head weigher can reach 120 bags/minute

*** The accuracy of dynamic weighing is accurate----±0.1~2.0g

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