As a technical team deeply engaged in the field of packaging machines, we think about a question every day: how to make the equipment's fluid control system more accurate and reliable? Especially in key links such as filling and sealing, the stability of packaging machine fluid control directly determines the product yield and production efficiency. Today, let's take you to understand our factory's exploration and practice in pneumatic and electric fluid control technology.
Pneumatic system: a "veteran" of stability and efficiency
Pneumatic systems have always been the traditional main force of packaging machine fluid control. Most of the equipment designed by our factory in the early days adopted pneumatic valve control technology, which drives the actuators through compressed air to achieve directional delivery of liquids or semi-fluids. The advantages of this solution are obvious-simple structure, low maintenance cost, and especially suitable for high-frequency start-stop conditions.
But the pneumatic system also has shortcomings. For example, air pressure fluctuations in the workshop may affect the accuracy of fluid control, and aging of the pipeline after long-term use can easily lead to increased energy consumption. In order to solve these problems, our engineers have carried out modular upgrades on the pneumatic unit. By adding a buffer and pressure stabilizing device, the fluid pressure fluctuation is controlled within 70% of the industry average. At the same time, the seal material is optimized to extend the replacement cycle of the key valve body.
Electric system: a "newcomer" of precision and intelligence
As customers have higher and higher requirements for packaging accuracy, our factory has started to develop electric fluid control systems three years ago. This system uses a servo motor to drive the pump body, and with high-precision sensors, it can adjust the flow rate and flow rate in real time. It is particularly suitable for fields with strict requirements on filling volume such as medicine and high-end food.
"The biggest advantage of the electric system is 'programmable'." Xiao Li from the project team introduced while debugging the equipment, "For example, when the same packaging machine switches fluids of different viscosities, you only need to enter the parameters on the control panel, and the system can automatically match the best delivery mode, which is difficult to achieve with traditional pneumatic systems." At present, our factory's electric fluid control module has been successfully applied to the production lines of multiple customers, and the measured filling error is stable and lower than the industry standard.
Pneumatic + electric: hybrid solution creates an all-round player
In actual applications, we found that it is difficult for a single system to meet all needs. Therefore, our factory innovatively launched a hybrid fluid control solution that combines pneumatic and electric systems - retaining the high efficiency of pneumatics in high-speed and low-precision links, and introducing precise control of electric systems in scenarios such as quantitative filling and viscosity adaptation.
Last year, a daily chemical enterprise customer tasted the sweetness of the hybrid solution. Their production line needs to handle two products, detergent (high viscosity) and alcohol spray (low viscosity), at the same time. The traditional equipment has a high leakage rate due to unstable fluid control. The "pneumatic and electric dual-control" packaging machine we customized for it not only reduced the leakage rate by 40% by intelligently switching between two modes, but also reduced energy consumption by 30%. The customer exclaimed: "This is the solution that truly understands production!"
Future direction: Make fluid control more "smart"
Whether it is pneumatic, electric or hybrid system, our factory's goal has always been to make the fluid control of packaging machines more in line with customer needs. Next, we are exploring the implantation of AI algorithms into the control system to automatically optimize the conveying parameters by learning fluid characteristics and equipment status in real time. At the same time, we are also developing a universal adapter interface to help old customers upgrade the fluid control module of existing equipment at a low cost.
