Two Components High Pressure Foaming Machine PU Sofa Making Machine
Polyurethane high pressure foaming machine uses two raw materials, polyol and Isocyanate. This type of PU foam machine can be used in various industries, such as daily necessities, automobile decoration, medical equipment, sports industry, leather footwear, packaging industry, furniture industry, military industry.
1) The mixing head is light and dexterous, the structure is special and durable, the material is synchronously discharged, the stirring is uniform, and the nozzle will never be blocked.
2) Microcomputer system control, with humanized automatic cleaning function, high timing accuracy.
3) The metering system adopts high-precision metering pump, which has high metering accuracy and is durable.
1. The equipment is equipped with production management control software, which is convenient for production management. Mainly refers to the proportion of raw materials, injection times, injection time, station formula and other data.
2. The high and low pressure switching function of the foaming machine adopts the self-developed pneumatic three-way rotary valve to switch. There is an operation control box on the gun head. The control box is equipped with a station display LED screen, an injection button, emergency Stop button, cleaning rod button, sampling button. And it has a delayed automatic cleaning function. One-click operation, automatic execution.
3.Process parameters and display: metering pump speed, injection time, injection pressure, mixing ratio, date, temperature of raw materials in the tank, fault alarm and other information are displayed on a 10-inch touch screen.
4. The device has a flow test function: the flow rate of each raw material can be tested individually or at the same time. The PC automatic ratio and flow calculation function is used in the test process. The user only needs to input the desired raw material ratio and total injection amount, and then input the current The actual measured flow, click the confirmation switch, the equipment will automatically adjust the required speed of the A/B metering pump, and the accuracy error is less than or equal to 1g.
