The multi head weigher is a newly emerging mechanical equipment recently. This multi-head weigher uses a high-precision load cell to instantly select a suitable combination from a wealth of weight combinations through computer calculation. Now the multi-head weigher has been sold all over the world and has been well received by users.

This is the picture of multi head weigher:

The working principle of multi-head weigher:

1. In the upper feeding hopper, the material is vibrated through the main vibration plate, so that the material is distributed on the conical funnel to the linear vibration plate.

2. When there is no or not enough material in the line vibration plate, it will be detected by the material re-module. This is to send a feeding signal to the main board, and then send a feeding signal to the material conveyor through the main board to feed until the material is detected.

3. The line vibration machine vibrates, drives the line vibration plate to vibrate, adjusts the appropriate amplitude and vibration time to send a certain range of material weight to each village hopper.

4. The driving device is a stepping motor, and the door of the storage hopper is opened, and the material is sent to the weighing hopper. When there is no material in the weighing hopper below or when there is not enough material in the weighing hopper, the village hopper will automatically open the door to put the material in We are all weighing.

This is the packaging machine with multi head weigher:

 5. In the weighing hopper, the weight signal is generated by the sensor through the sensor, and then transmitted to the main board of the control device through the lead. The CPU on the main board reads and records the weight of each weighing hopper, and then calculates, analyzes, and combines them. Filter out the combination weighing hopper closest to the target weight. When receiving the unloading request signal sent by the packaging machine, the CPU sends a signal to start the weighing hopper motor driver to open the selected weighing hopper and unload the product into the feeding trough. Packing Machine.

6. When the weighing hopper has finished placing the materials, the multi-head scale will send a signal to the packaging machine that it has been discharged, and the packaging machine will start to seal and cut the bag when the packaging machine receives the signal. The multi-head weigher sends a request signal to call the multi-head weigher to unload, and so on.
