Construction Principle

1. Feeding part: Adopt two kinds(big one and small one)valves to control the three kinds feeding: fast, slow and exact mess.
2. Weighing shelf:The weighing shelf connected with sensor,and convey the weight signal to the electric box which controlling the operation of the machinery.
3. The electromotion car operated by the motor and run in the track to convey the products.The car’s position controlled by the worker and the final position is determined by the limit switch.
4. Electric box:Exterior signal and the sensor signal are conveyed to the electric box,which could control the feeding ON and OFF, cylinder lifting and the car running through finished program.
