Product Characteristics
1. This machine is used for win-color and single-color polyurethane earplugs and so on.
2. Continuous automatic production line can increase production capacity and reduce the
rejected products.
3. Mold using water heating, guaranteed the stability temperature of the mold.
4. The whole equipment adopts PLC programming, automatic control, pouring,
closing molds, the equipment head using automatic cleaning.
The main technical parameter soft the equipment and instructions
1. Output (5~20g/s)
2. Suitable temperature :Between 20-60
3. Injection time:0.01-99.9(accurate to 0.01S)
4. Number of injection procedures:
Manual injection:10
Automatic injection:255
5. Metering unit: component metering,metering accuracy 0.5%. gear speed motors ;couplings; high-precision displacementgear metering pumps; safety valve ;pressure sensor ;speed sensor.
6. Pressure limit and control system
The polyether polyol and isocyanate component working pressure control in 0-4MPA,If the working pressure exceeds settled pressure range, the device will automatically stop injecting material and give an alarm.
7. Flow measuring and controlling system
According to the flow rate of the pump output and component mixing ratio process r equipment sand parameters, the components flow output flow of the pump by adjusting the rotational speed of speed regulation motor. Remove the mixing head ,with the their respective feed injection valve, make A, Braw materials flow to their respective container, check each component flow parameters separately, and the correction to achieve the regulation and control of the component flow rate and corectin order to achieve the regulation and control of the component flow rate.
8. Components filter
The two components are respectively equipped with a mesh filter; the components filterin stalled between the metering pump and tank, the filtering work are done by cleaning on are gular date and opening the sewage valve.
9. Mixing head.
The materials are injected by the valve to the mixing chamber, precision spit, and synchronization without clogging. Mixing head driven by a motor to mix mechanically. The motor and the agitation axis are driven by a belt; the speed can be adjusted by the motor pushing and pulling.
When test status, the motor and mixing does not rotate. Agitating in advance or postponed, controlled by the polyurethane dedicated equipment controller, optional automatic mixing and manual mixing of the two modes. The open and close of the valveis controlled by the cylinder. Mixing head, mixing chamber as well asfan-shaped mouth facilitate the demolition. The pressure balance can be adjusted ,agitation by using a conical mixing head. Two sets casting mixing head, mixing head. Casting machine computer hasself-cleaning, air impact, emergency stop button.
10. Mixing head cleaning system
Mixing head cleaning system include 15L stainless steel barrel ,visual level gauge, safety valve, super charged device and related instrument. Solenoid valve control the air blast and liquid washing. The compressed air is used for blowing out of the mixing head residue and drying solvent.
