Polyurethane Dumbbell Making Machine PU Elastomer Casting Machine
1. The raw material tank adopts electromagnetic heating heat transfer oil, and the temperature is balanced.
2. High temperature resistant and high precision volumetric gear metering pump is used, with accurate measurement and flexible adjustment, and the measurement accuracy error does not exceed ≤0.5%.
3. The temperature controller of each component has a segmented independent PLC control system, and is equipped with a dedicated heat transfer oil heating system, material tank, pipeline, and ball valve with the same temperature to ensure that the raw materials are kept at a constant temperature during the entire cycle, and the temperature error is ≤ 2 °C .
4. Using a new type of mixing head with a rotary valve, it can accurately spit out, with superior performance, uniform mixing, no macroscopic bubbles, and no material.
5. It can be equipped with a color paste control system. The color paste directly enters the mixing device, and can switch different colors at any time. The mixing is uniform and the measurement is accurate.
Material Tank
Tank body with three layer structure: Inner tank is made of acid-resistant stainless steel (argon-arc welding); there is spiral baffle plate in the heating jacket, making heating evenly, To prevent the heat conducting oil temperature too high so that the tank material polymerization kettle thickening. Out layer pouring with PU foam insulation, the efficience is better than the asbestos, achieve the function of low energy consumption.
Pour head Adopting high speed cutting propeller V TYPE mixing head (drive mode: V belt), ensure even mixing within the required pouring amount and mixing ratio range. Motor speed increased through a synchronous wheel speed, making the mixing head rotate with high speed in mixing cavity. A, B solution are switched to casting state by their respective conversion valve, come into the mixing champer through orifice. When the mixing head was at high speed rotation, it should be equipped with reliable sealing device to avoid pouring material and ensure the normal operation of the bearing.
