1Measurement and conveying system with closed-loop control

The equipment system digitally monitors the glue pressure of the feeding pump and the remaining glue in the A and B raw material buckets, and introduces the function of the control system. The control process is as follows: every about 0.01 seconds (i.e. one PLC scanning cycle), the flow rate of A and B glue is compared, and the error between the two is calculated. The difference is then used for PID calculation, and the calculation results are used to adjust the various parameters of the feeding system, thereby achieving closed-loop control of the output ratio. This dynamic adjustment process ensures more accurate proportioning, and this control mode enables the proportioning accuracy of the feeding system to reach within ± 1%, providing favorable conditions for product quality assurance.

2Hydraulic continuous synchronous metering system

In terms of measurement, we have developed and designed a hydraulic continuous synchronous measurement system based on the measurement characteristics of the feeding system in the power industry. It breaks the traditional hydraulic control method and adopts a motor plunger pump structure. The synchronous structure adopts a compensation design to ensure the durability of the equipment. This system has the advantages of no maintenance, cleanliness, low oil temperature, and low energy consumption

3Digitization of equipment parameters

Many parameters of traditional feeders are not displayed. E523 digitally monitors the condition of raw materials and digitizes pressure and output speed. The pneumatic system of the feeding system is digitally regulated using an electrical proportional valve.

The above important parameters can be monitored and adjusted through the touch screen.

4Closed loop control of flow rate

E523 liquid silicone gelfeederWhen considering the injection of products by power product users, it is necessary to directly output the feeding machine in a quantitative manner according to the cavity volume, and to consider the adaptability of the injection process during the injection process, it is necessary to be able to adjust the injection speed. Therefore, E523 not only has the ability of quantitative injection and segmented injection in its design, but also utilizes a new flow closed-loop control concept to monitor the output flow in a closed-loop manner, greatly improving injection accuracy.

This not only meets customer needs but also further reduces waste of raw materials for users.
