Simple foam cutting machine production method principle
It is enough to connect a piece of resistance wire between two simple wires. After plugging in the foam sheet cutting machine, the resistance wire will heat up. Two people can cut it after straightening it.
Get a resistance wire and connect it with direct current. The voltage depends on the heating of the EPS foam plastic machinery and equipment. As long as the resistance wire is heated to a certain degree, the foam can be cut directly.
Materials prepared for foam cutting machine
Using a 12V120W transformer can ensure sufficient current for the price of the foam machine. Note: 36V200W transformer cannot be used. Recently, it has been found that it is better to use heating wire than resistance wire, which is very energy-saving, economical and simple. Adjust the current until the heating wire turns slightly red. Dimming can be used to turn on the light, which is simpler and more economical; but the power of the thyristor must be increased to use it, or there are special ones to buy. A workbench, a wooden case, a step-down transformer, 20 watts, secondary tap voltage 12 volts, resistance wire, a piece of stainless steel wire, 0.3 mm in diameter, 1.5 m long , wooden blocks
Foam cutter to make combo connections
One end of the resistance wire is fixed on the case, and the other end is tied to the spring. The spring is properly pulled apart and fixed on the case. The two ends of the resistance wire are connected to the two taps of the transformer secondary through the connecting wire. As high as the required height, the primary of the transformer is connected to the mains power supply through a switch. The principle of resistance wire is energized to generate heat, which can melt the polypropylene or polystyrene foam board and separate the foam board.
