The electric quantitative packaging scale is a new type of quantitative packaging scale that has emerged only in recent years. Its major innovation lies in the use of a mechanical actuator driven by a stepping motor to replace the pneumatic actuator of traditional packaging scales. This innovation holds significant practical significance in actual production. Since the electric quantitative packaging scale emerged, it has caused a huge response in the market. Currently, the electric quantitative packaging scale has replaced traditional pneumatic models in many industries and has become a suitable choice at present.
The main differences between electric packaging scales and pneumatic packaging scales are reflected in the following aspects:
The initial emergence of the electric quantitative packaging scale was to solve the problem that pneumatic packaging scales could not be used normally in the winter in the north due to the extremely low temperature. Because compressed air contains moisture and oil, once the temperature is too low, these substances in the air path are very likely to freeze, causing the air path to freeze and become blocked. This results in the pneumatic actuator being sluggish and weak in action, leading to the packaging scale being unable to work normally. The action execution mechanism of the electric packaging scale is driven by a computer-digitally controlled stepping motor to complete the mechanical mechanism, which has good adaptability to low temperatures. The stepper motor is equipped with control signals such as pulse signals and direction signals sent by the computer to precisely control the rotation position and Angle. The flexible position and multi-speed control can easily achieve stepless speed regulation and multi-speed feeding. The control of precision and speed is more flexible, enabling the packaging scale to adapt to the precision and speed requirements of more different materials. These are impossible to achieve for cylinders with a certain stroke.
Electric packaging scales are applied in the industry of corrosive materials and also have inherent and unique advantages in anti-corrosion. The electric mechanism itself has better corrosion resistance than the pneumatic one. In the corrosion-resistant industry, due to the structural advantages of the electric packaging scale, it is easier to better seal the actuator structure, which will greatly enhance the corrosion resistance of key components.
