SL-300 Universal Dynamic Checkweigher


It is mainly used for product quality detection and classification on automatic assembly line, and also for the detection of many or missing parts after product packaging. It can also replace manual weighing, so as to improve the production efficiency and the consistency and reliability of weighing. Widely used in electronics, pharmaceutical, food, beverage, health care products, daily chemical, light industry, agricultural and sideline products and other industries. Such as food industry conditioning products, cakes, ham sausage, instant noodles, frozen food, food additives, pigments, modifiers, preservatives and so on.    

Product features:

Strong commonality:The machine standardized structure and standardized man-machine interface can complete the weighing of various materials;

The operation is simple:Using Weilun color human-machine interface, fully intelligent, humanized design; Conveyor belt is easy to disassemble, easy to install and maintain, easy to clean;

Speed is adjustable:Frequency conversion control motor, speed can be adjusted according to need;

High speed, high precision:High precision digital sensor, fast sampling speed, high precision;

Zero tracking:Manual or automatic zero clearing, and dynamic zero tracking;

Interface function:Reserved standard interface, convenient data management, can communicate with PC and other intelligent devices;

Self-learning:After creating the product formula information, there is no need to set the parameters. The self-learning function is used to automatically set the parameters suitable for the device, and the storage is convenient to call the next time when switching products. (Parameter storage items 2000, can be increased).

Operating mode:Three operating modes

A.The dynamic model:Normal pipeline mode;

B.static model:After the material enters the weighing platform, the weighing platform stops operation and is weighed to improve the accuracy. It is suitable for products with less than 20 passes per minute;

c.Energy saving mode:(optional) On the basis of A and B modes, energy saving mode can be opened. Set the downtime period when no material passes. When the equipment idles for a long time, it will automatically stop.

Automatic fault detection:Self-detection: motor, inverter, AD, sensor and photoelectric normal and fault causes and cylinder, solid state relay, solenoid valve guidance detection. Convenient for non-professional inspection and maintenance.

Peripheral communication:Standard RS-485 and RS-232 double communication port output.

a.The RS-485 interface is MODBUS, RTU standard protocol, but can modify the write address (57600bps, 8, N, 1, slave station number is 3) cannot be modified.

b.(optional)  The RS-232 interface is a user-defined protocol, and you can set the content of sending commands by yourself. (57600bps, 8, N, 1) can be modified.

Communicated devices such as external printers or coding machines can also be connected to front and rear packaging machines and production equipment to feedback weighing results so that formula parameters can be automatically modified.
