When the rotating shaft 4 rotates, the fixed block 2 will drive the traction rod 3 to rotate with the rotating shaft 4 as the center of the circle, so that the solder paste bucket between the two traction rods 3 slides along the inner wall of the tank body 1, and the front and rear ends of the tank body 1 are both provided with a guide hole 13 located at the bottom end of the tank body 1, and the rear end of the tank body 1 is fixedly connected to a blower 11 near the top of the tank body 1, and the port of the blower 11 is located inside the tank body 1;

[0021] The rear end of the tank body 1 is fixedly provided with a material guide box 6 close to the edge of the tank body 1 and its bottom end is located directly below the motor 5. The bottom end of the material guide box 6 is provided with a round hole corresponding to the guide hole 13 located at the rear end of the tank body 1. The cylinder poured into the material guide box 6 will slide along the inner wall of the material guide box 6 to between the guide hole 13 and the round hole. The material guide box 6 is arranged in an arc shape. The top of the material guide box 6 is provided with a horizontal port for convenient feeding of the solder paste cylinder. The port is connected to the conveyor belt. A slide rod 9 is slidably inserted in the round hole. The length of the slide rod 9 is greater than the width of the material guide box 6. The bottom end of the slide rod 9 can be slidably inserted in the guide hole 13, and the slide rod 9 is away from one end of the material guide box 6. It is fixedly connected with a fixing plate 8, and a hydraulic cylinder 7 is fixedly provided at the rear end of the tank body 1.
