In a preferred embodiment, two feeding conveying pipes 6 which are connected with the bottom of the resin tank 2 and are provided with feeding pneumatic valves 4 are arranged, and the feeding conveying pipes 6 are arranged between the inner wall of the resin tank 2 and the conical body 3; the resin continuous heating metering components 51 connected with the feeding conveying pipe 6 are divided into two groups; two discharging conveying pipes 7 which are connected with the bottom of the resin continuous heating metering assembly 51 and are provided with discharging pneumatic valves 5 are arranged.

Optionally, an electric hoist 1 may be provided on the top of the resin tank 2 for placing resin into the resin tank 2.

Optionally, a resin heating metering assembly 51 may be positioned above the high speed mixer 8 for discharging the material into the high speed mixer.

Referring to fig. 2, the resin continuous heating and metering assembly 51 includes a heat-insulating jacket 13 and a resin metering barrel 12 disposed in the heat-insulating jacket 13 for containing resin, a resin heating pipe 11 for heating resin is disposed on the resin metering barrel 12, a jacket layer 14 for containing heat-conducting oil is formed between the heat-insulating jacket 13 and the resin metering barrel 12, a jacket heating pipe 10 for heating heat-conducting oil is disposed in the jacket layer 14, and an electronic metering sensor 9 for weighing resin is disposed on the resin metering barrel 12.
