[0019] In this embodiment, if Figure 1As shown, a reactor includes a frame 8, on which a mixing box a2 and a glue pump 9 are installed. A heating layer 3 is provided on the surface of the mixing box a2. The discharge port of the mixing box a2 is connected to the mixing box b6, and the discharge port of the mixing box b6 is connected to the feed port of the glue pump 9. The discharge port of the glue pump 9 is connected to the glue rod 10, and the end of the glue rod 10 is provided with a glue coating head 11. The upper end of the mixing box a2 is provided with a cover plate 4, and the cover plate 4 is provided with a feeding port 5 and a cycloidal pinwheel reducer 1. The power output end of the cycloidal pinwheel reducer 1 is connected to the rotating shaft 12, and the end of the rotating shaft 12 is located in the mixing box b6. A spiral blade 13 is provided on the surface of the rotating shaft 12. A stirring mechanism a is also provided on the rotating shaft 12. The stirring mechanism a is located in the mixing box a2, and a glue temperature probe 7 is provided in the mixing box a2. Furthermore, the pitch of the spiral blade 13 located in the mixing box a2 is greater than the pitch of the spiral blade 13 located in the mixing box b6. The cycloid reducer 1 drives the rotating shaft 12 to rotate, thereby driving the spiral blades 13 and the stirring mechanism a to rotate. During the rotation process, the spiral blades 13 and the stirring mechanism a will turn the rubber material in the stirring box a2 and the stirring box b6, thereby ensuring the uniform temperature of the rubber material in the reactor. At the same time, the stirring mechanism a will scrape the rubber material on the inner wall of the stirring box a2 during the rotation process. The temperature is then measured in real time by the glue temperature probe 7. The glue pump 9 feeds the rubber material to the glue coating head 11 for glue coating, thereby achieving simultaneous glue coating and stirring, making the hot melt adhesive morphology stable and ensuring product quality. In this embodiment, the glue material is added through the feed port 5, and the stirring box a2 uses the existing industry heating method to heat the rubber material in the stirring box a2, that is, the heating layer 3 is an existing product. At the same time, the glue pump 9, glue coating head 11, cycloid reducer 1 and glue temperature probe 7 are all existing products. They have not been improved here and will not be described in detail.

[0020] Further, if Figure 2 As shown, the stirring mechanism a includes a stirring paddle 14, which is arc-shaped, and one end of the stirring paddle 14 is connected to the upper end of the rotating shaft 12, and the side surface of the other end of the stirring paddle 14 is in contact with the inner side surface of the stirring box a2. A fixing rod 15 is provided between the end of the stirring paddle 14 in contact with the inner side surface of the stirring box a2 and the rotating shaft 12. Specifically, when the cycloid pinwheel reducer 1 drives the rotating shaft 12 to rotate, the stirring paddle 14 will rotate synchronously. During the rotation process, the stirring paddle 14 will turn the rubber material in the stirring box a2 to ensure that the temperature of the rubber material in the stirring box a2 is uniform. At the same time, since the end side surface of the stirring paddle 14 is in contact with the inner side surface of the stirring box a2, it can scrape the rubber material on the inner wall of the stirring box a2. The main function of the fixing rod 15 is to enhance the rotation stability of the stirring paddle 14.

[0021] In this embodiment, the mixing box b6 is tapered. Specifically, the mixing box b6 is tapered to facilitate discharging.
