Nantong Geze Machinery Manufacturing Co., Ltd.
The sponge automatic horizontal continuous foaming production line is mainly suitable for soft polyurethane sponge with a density range of 7-80kg/m3.
produce.
The foam foaming machine adopts a man-machine interface control system with high degree of automation and more flexibility. (The machine has two configurations: automatic manual control and automatic human-machine interface.) Users can store 200 different sponge hairs. The foam formula can also be adjusted or changed at any time, and can be remotely controlled through the Internet, so that the control of the production sponge cost is more scientific and intuitive.
The sponge foaming machine can directly change the formula without stopping the flow. It does not need to measure the flow rate, and the yellowing resistance can reach the international standard of 3 levels. It is used to produce all kinds of ideal furniture cotton, shoe material cotton, bust cotton, electronic cotton. And a variety of sponges for the packaging, garment and automotive industries. Cooperate with the manufacturer to provide formula and foaming technology training. .
Sponge raw material storage tank: The size of the storage tank should be related to the foaming field equipment. The storage tank is too large, too small, too thick, too thin will increase the unfavorable factors of foaming.
Pump: The size of the pump is related to the foaming flow range and the diameter of the output tube. The output per revolution is the main parameter of the gear pump.
Pipe: It must be matched with the flow range and the size of the pump.
Pneumatic Steering Valve: This means that the material enters the mixing chamber or enters the return pipe during operation. The steering valve of the powder-added component and the TDI component is likely to be dead or not in place, and should be noted.
Small tank mixing chamber: its diameter and length are important parameters and are also the basis for calculation.
Pouring: Based on the principle of uniformity and continuity. The swing frequency, conveyor speed, and foam launch speed of the swing should be coordinated.
Foaming overflow tank: The tank volume is 20-60 liters, and the tank volume determines the residence time of the raw material in the tank.
Settlement plate: If the foaming bottom plate of the assembly line is straight, the conveyor belt is opened. This is the curve of the upper part of the bubble. Conversely, this curve is placed on the bottom plate of the line. The upper part of the bubble is a straight line. This is the principle of the flat top of the settling plate. The basis for the adjustment of the sinker. The drop and length of the settling plate are the main parameters and must be matched with the conveyor belt speed and the viscosity of the reaction system.
Sponge foam mixing head mixing speed: related to foaming internal pressure, flow rate, and formulation reaction speed. Usually 4000-5000 rpm.
Air: As the air increases, the cells tend to become thinner. However, when the air increases to a certain amount, the cells do not become fine and the bean holes appear, so it should be accurately grasped, usually 50-150.
Foaming pressure: An increase in pressure will increase the shearing force of the agitation, which will destroy the number of initial nucleation sites and make the cells thicker. Usually 1.8-2.4 atmospheres.
TDI delay: the time that TDI will spit out later to prevent the bubble from burning. Usually set to 0.1-1 seconds.
Conveyor speed: related to the speed of the conveyor and the sinker. The speed of the conveyor belt is stricter.
