| description | A charging barrel of plastic extrusion machine is provided with a feed inlet and a discharge port. The inside of the charging barrel is provided with a feed rod which is driven by a motor, and the charging barrel is provided with a heating device and a temperature sensing device, and an insulating layer is arranged outside the charging barrel. The heating device comprises a sensing coil which is insulated from the charging barrel outside the insulating layer, and the sensing coil is connected with a high-frequency power supply. Because of the sensing coil outside the insulating layer and the connection between the sensing coil and the high-frequency power supply, the high-frequency eddy current generated on the charging barrel heats the charging barrel when the high-frequency power supply is switched on, and the heat efficiency is higher by more than 50% than that generated by employing electrothermal tubes or heating wires. The sensing coil is arranged outside the insulating layer, thereby reducing heat diss |
