The ton bag packaging scale is very popular in the market, but many people are not very familiar with the components of the packaging scale. Next, we will briefly introduce the main components of the packaging scale and the main functions of each component.
The main components of the packaging scale are solenoid valve, material level meter, electric valve, bag clamp limit switch, weighing indicator and its weight sensor, etc.
1. Weight sensor, which mainly outputs the weighed net weight value to the weighing indicator as a working voltage signal
2. The solenoid valve mainly includes feeding butterfly valve, exhaust butterfly valve, slow discharge valve, air supply valve, back blow valve, fast discharge valve, bag clamping valve and bag turning valve, which mainly play the role of regulating butterfly valve and valve. Efficacy of cylinder operation.
2. The electric valve in the ton bag packaging scale system is also a key component. In the electric valve, it can also be divided into a fluidization valve and an exhaust valve, which are mainly used to control the connection and interruption of the fluidization gas source. For the material level meter, it is a type of normally open contact. When the material in the fluidized silo reaches a certain height, the corresponding relay is energized and outputs a response to the PLC. In addition, the bag clamping schedule is arranged. The button is a passive contact, which usually sends out a pulse signal to the PLC after being touched.
3. In the packaging scale, an indispensable component is the weighing aspect. At present, you mainly use the weighing display, which contains 8 input points and 12 output points to complete logical control. Generally speaking, The sensor interface is connected to the weight sensor to complete the solution to the net weight parameter.
4. The key component is PLC, which mainly solves and controls various data information of the ton bag packaging scale.
