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.

D523 has achieved the most important technical indicator for the feeding system - proportioning accuracy, realizing closed-loop control and improving the proportioning accuracy of the LSR feeder by an order of magnitude.

The following is the A and B adhesive balance data tested by D523 at the customer's site:

According to our testing over the past two years, the best record for A and B glue balance is an error rate of only0.07%I believe these data are exciting good news for users pursuing high-quality LSR injection molding.

Due to A and BDuring the design and experimentation of the rubber material, a 1:1 specification is followed, and the material properties that can be achieved are also given under the condition of a 1:1 ratio of two component materials. However, in actual use, traditional feeding systems do not truly guarantee this, resulting in the material properties of the product after molding not fully meeting the design requirements. For situations with high requirements, such as bonding, high transparency, and human implantation, quality issues may arise or the service life may be greatly shortened.

The D523 feeding system has completely solved this problem, giving customers confidence in their products.

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, and has been well received in the industry

3Digitization of equipment parameters

Many parameters of traditional feeders are not displayed. D523 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.

As shown in the picture:

Power on screen, distinguishing users of different levels by password

main menu

Automatic screen, from which technical data such as pressure, flow rate, and output can be monitored during injection in the feeding machine

Manual screen, which can also monitor the pressure changes of pumps A and B, as well as the output status of PLC output points during manual operation, making it convenient for inspection.

Manual screen two can monitor some raw values. After manual operation is completed, it is convenient to load the initial height of the raw materials and enter the working state of the A and B ratio calibration system.

Parameter screen one allows setting the basic data for the device's operation.

Parameter Screen 2, Basic Data of the Equipment

Parameter screen three, user injection data.

Users can set the injection volume, as well as the pressure and flow rate during injection, and can also divide it into four injection stages for easy adjustment of the injection process.
