1.High degree of user-friendliness: Various parameters can be set according to user needs, automatic alarm for out-of-tolerance, power failure parameter protection function to meet new control functions, quantitative control instruments with parameter backup and recovery functions, Communication interface, can be connected to the production management system at any time;2.The multi-stage combined feeding method can realize 21 modes of feeding in 6 modes, and the size of the feeding port can be adjusted, which increases the feeding speed of the large package and achieves the accuracy of the large package; at the same time, the electromagnetic vibration straight line is used. The feeding method, so the speed of small packaging is fast and the accuracy is high;3.Dual instrument control: using German B.L weighing technology chip, 360 conversions per second, fast speed, using two instruments, long life, one instrument failure, the other side can also be produced;4.Pneumatic components are 100% German Festo, with more stable quality and longer life;5. The conveyor adopts a custom sewing head, the first domestic optical fiber sensing technology, automatic sewing and automatic thread cutting, the length of the thread head is controllable, and manual sewing can be realized. Frequency conversion speed regulation ensures that the suture is flat and beautiful;6.The load cell is made of "arm-type" alloy steel and has a long service life;7.Wide range of packaging and fast speed: It can achieve the packaging range of 0.1-50 kg / bag, and the weighing speed can achieve 450-1400 bags / hour. It is the widest weighing range, fastest speed and precision in domestic double body scale.8.Contact with the material is made of stainless steel to ensure that the production meets the requirements of sanitary standards;9.The total package weight and number of bags will be accumulated.10.with weighing, unloading and bag clamping process chain control functions.11.with automatic and manual adjustment conversion function.
