This model is suitable for the production of polyurethane noise-proof earplugs, earplugs, sleep earplugs, multi-functional acoustic earplugs, aviation earplugs and other products.

Space earplugs automatic production line is the liquid polyols and isocyanates two components of the raw materials are stored in two material storage tank, with two rotary precision gear metering pump to the mixed system, the pressure under the action of mixing head open, two components were injected into the small in the mixing chamber, a mixing blade high speed stirring and mixing effect, make the material liquid evenly, to form the required product.

Technical parameters of automatic aerospace earplug production line：

Head: high performance mixing device, material spit out accurate synchronization, mixing evenly; New sealing structure, reserve cold water circulation interface, ensure long time continuous production without blocking.

Metering pump, frequency conversion motor: high precision metering pump, precise proportioning, measurement accuracy error no more than ±0.5%; By frequency conversion motor with frequency conversion to adjust raw material flow, pressure, high precision, simple and quick proportional adjustment.

Touch screen: PLC and touch screen man-machine interface are used to control pouring, automatic cleaning and air flushing of the equipment, with stable performance and strong operability. When abnormal conditions occur, it will automatically discriminate, diagnose and alarm, and display abnormal factors.

Mould frame: it has the function of automatic timing mould opening and automatic closing, which can ensure the curing and constant temperature time of the product, so that the product can meet certain physical property requirements.Material tank: adopt three-layer material storage tank, stainless steel inner tank, sandwich type heating, outside insulation layer, adjustable temperature, safety and energy saving.
