The mixing head adopts a rotary valve type three-position cylinder, which controls the air flushing and liquid washing as the upper cylinder, controls the backflow as the middle cylinder, and controls the pouring as the lower cylinder. This special structure can ensure that the injection hole and the cleaning hole are not blocked, and is equipped with a discharge regulator for stepwise adjustment and a return valve for stepless adjustment, so that the entire pouring and mixing process is always synchronized and consistent, thus ensuring the product quality.
Using high-precision metering pump and variable frequency motor to adjust the speed, the adjustment is accurate, the operation is stable, and the operation is convenient.
The working procedures of pouring, cleaning and air flushing are automatically controlled by PLC program control. The temperature, speed and injection parameters are displayed on the 10-inch touch screen.
Using acid-resistant stainless steel to heat (or cool) the interlayer material tank, the interlayer is equipped with a tubular electric heater, the outer layer is insulated with polyurethane, and is equipped with cooling water inlet and outlet and moisture-proof drying cup interface in the material tank to ensure raw materials. The quality and temperature are stable.
