The automatic Filling machine is made of PLC programmable controller, the filling head and pipeline adopt quick joint, easy to disassemble and wash, and adopt two-stage automatic filling mode. When the filling head is not inserted into the barrel, it automatically picks up. Reach the filling target value, the filling head automatically rises, the net weight/gross weight two filling methods can be freely selected, 30 groups of formula can be set and stored for calling, the filling target quantity can be freely set, convenient for various weight packaging. Weighing table no barrel to prohibit filling, differential pressure zero time difference drum protection, automatic peeling, intelligent anti-stay, fault detection, can achieve a single person at the same time filling and locking operations.

The weighing and filling machine uses PLC and industrial microcomputer to build a high-performance control platform, and adopts a three-stage speed feeding mode. PLC controls the frequency converter by different combinations of output switching quantity to achieve fast feeding, slow feeding and fine feeding. Fast feeding at the beginning of weighing and slow feeding when the given value of fast feeding prediction is reached; When the given value of slow feed prediction is reached, the fine feed starts; Stop filling when the total feed weight reaches "target weight - pipe weight - allowable error", where pipe weight is the material weight remaining in the pipe that will continue to flow into the filling barrel after the motor stops rotating, and the optimal value is taken from the actual filling, and the target weight and allowable error are set by the touch screen.
