A motor 103 is arranged above the material barrel 104 for rotating a stirring rod 105. The interior of the material barrel 104 is symmetrically provided with stirring rods 105 from top to bottom. The rotation of the stirring rods 105 can put the glue in a moving state, thereby improving the uniformity during heating. A heating wire 10 is arranged inside the lower wall of the material barrel 104. 41, used to generate heat to heat the glue, the front and rear of the barrel 104 correspond to the upper walls of the mounting frame 107 respectively fixed with a delivery pump 109 and a fan 110, the delivery pump 109 is used to deliver the glue to the rectangular box 1072, the fan 110 is used to generate airflow, the right wall of the mounting frame 107 is fixed with a mounting box 108, the interior of the mounting box 108 is connected to the interior of the three-way pipe 1101, the above arrangement, the rotation of the stirring rod 105 is used to put the glue in a moving state to improve the uniformity during heating, and the airflow generated by the fan 110 is used to make the hot air flow evenly act on the inner wall of the barrel 104 so that the inner wall of the barrel 104 is evenly heated, further improving the uniformity during heating.

[0031] Specifically, the mounting frame 107 is U-shaped, the material barrel 104 is double-layered, a barrel cover 102 is fixed to the upper wall of the material barrel 104, and the motor 103 is fixedly connected to the barrel cover 102, the barrel cover 102 can be fixedly connected to the material barrel 104 by bolts, a rotating rod 1031 is fixed on the power output shaft of the motor 103, and the stirring rod 105 is fixedly connected to the rotating rod 1031, when the rotating rod 1031 rotates, the stirring rod 105 can be driven to rotate, a material pipe 1021 is fixed to the upper wall of the barrel cover 102, and the external thread of the material pipe 1021 is connected to the pipe cover 101, after removing the pipe cover 101, glue can be added to the inside of the material barrel 104 through the material pipe 1021.
