The two pairs of compression rollers are driven by a motor to rotate.
The heating devices 5 are arranged between the two pairs of compression rollers, and the two heating modules are respectively arranged below the core material conveying channel. Since the temperature of the core material is high, the heating module heats the core material to prevent the temperature from dropping too fast, and the required heating temperature is high.
