1Passive continuous quantitative pumping system

This machine has continuous pumping and quantitative metering functions. The characteristics of this system are: A. It adopts a two in one secondary metering structure of pumping and metering. Compared with traditional split pumping and metering systems, the equipment volume is greatly reduced, and the pressure of the feeding system and the output ratio accuracy of the two-component system are improved; B、 The secondary metering section draws on the approach of synchronous systems, using the output of the primary feed pump as power. No power source is required in the secondary metering section, resulting in relatively reduced energy consumption. Due to its continuous measuring function, customers can form liquid silicone products weighing 0-400KG at once.

2Measurement and conveying system with closed-loop control

The equipment system has the function of digitally monitoring and introducing control system for parameters such as pressure plate pressure and feeding pump glue pressure. The control process is as follows: every about 0.01 seconds (i.e. one PLC scanning cycle), the flow rates of A and B glue are compared, and then the error between the two is calculated. The difference is used for PID calculation, and the hydraulic or pneumatic parameters are adjusted based on the calculation results to fine tune the flow rate. This dynamic adjustment process ensures more accurate proportioning. This control mode enables the proportioning accuracy of the feeding system to reach less than 1%, providing favorable conditions for product quality assurance.

3High pressure and high flow output

The system adopts a feeding pump with a maximum output (dual pump) of 10L/Min, and the injection pressure of the feeding system can be increased to a maximum of 25-40MPa. The injection flow rate can be adjusted arbitrarily between 0-10L/Min, which can achieve rapid injection molding of large products without reducing mold temperature, greatly shortening the production cycle and reducing energy consumption, and doubling production efficiency. This feeding system is different from previous domestic and foreign equipment in that it has a unique advantage in the ability to directly inject the mold cavity through the feeding machine without relying on other equipment, and has a unique advantage in rapid injection molding.

4Precise injection and segmented injection

The operator can directly input the required injection amount for different product molds on the human-machine interface. The feeding system calculates the output amount while feeding, and stops the injection automatically when the output reaches the set amount. The accuracy of injection volume can reach± 25g/20kgWithin.

According to the different designs of products and molds, the system can adopt different injection speeds in different injection stages to achieve optional segmented injection modes. The injection process can be divided into four stages, each with different injection speeds (flow rates) and injection pressures, to adapt to the optimization needs of different product molds and improve production efficiency and product quality.

5Formula function

According to the requirements of different injection parameters for different molds, the system can provide the formula storage function and the formula call function. After using the new mold, the optimized parameters can be saved as the formula. When using this mold next time, the formula can be called from the controller's memory according to the mold number, thus reducing unnecessary waste and workload caused by debugging.

6Pressure monitoring function

The system adopts a Siemens 10 inch 365 true color touch screen from Germany to directly display dynamic parameters such as system pressure, remaining rubber, flow rate, etc. In order to more intuitively understand the pressure changes during the injection process, a real-time pressure curve monitoring chart with time as the axis is designed to provide a more intuitive judgment and analysis of the rationality of the injection process.
