With the development of electronic technology and computer technology, multihead weigher is widely used in all walks of life, and through the simultaneous measurement by means of a microcomputer system. But how a multi head weigher calculate combinations?
The material falls through the hoist into the bucket of the combination weigher and vibrates through the main feeder, so that the material is evenly distributed on the conical funnel to the linear feeder pan. When there is no material or material in the bucket, it will be detected by the horizontal photodetector, send a signal to the main board, and then send the feed signal to the conveyor through the main board. The material is vibrated by a linear feeder, and the product is sent to each buffer hopper by amplitude and vibrator time. The drive device is then activated to open the buffer hopper and transfer the material to the weighing hopper.

In the weighing hopper, the material generates weight signal through the sensor, and then transmits it to the motherboard of the control equipment through the lead wire. The CPU on the motherboard reads and records the weight of each weighing bucket, and then selects the combination weighing bucket closest to the target weight through calculation, analysis and combination. Upon receiving the allowed release signal from the packaging machine, the CPU will issue a command to start the driver to open the hopper to unload the product to the packaging machine and send a packaging signal to the packaging machine.

The general single-head scale is about to reach the target weight. In order to ensure the accuracy, the feeding speed cannot be too fast. The amount of material in each hopper is usually set at 1/3 to 1/5 of the target weight. Only partial combination is used in combination calculation of combination scale. According to the number of heads participating in combination, the combination number can be calculated by the following formula: n=Cim=m! / I! (m - I)!
Where: m is the total number of weighing hoppers, and I is the number of buckets participating in the combination. Usually m, I increase, and the number of possible combinations increases, so the possibility of obtaining a good product is greater.
