The raw material injection mechanism 3 includes: an injection base 31, on which an inlet channel 3101, an outlet 3102, and a bypass port 3103 are provided. The inlet channel 3101, the outlet 3102, and the bypass port 3103 are interconnected. The bypass port 3103 is connected to a metering cylinder 32. The frame 1 is provided with a piston drive mechanism 33 for driving the piston of the metering cylinder 32. The inlet channel 3101 is connected to an inlet pipe 34. The injection base 31 is provided with an inlet switch 35 for opening and closing the inlet channel 3101. The outlet 3102 is connected to a guide pipe 36 connected to the mixing mechanism 2. A solenoid valve 38 is provided between the outlet 3102 and the guide pipe 36. The tubular dynamic mixer of this embodiment has a feed switch 35 on the feeding base 31 for opening and closing the feeding channel 3101, and a solenoid valve 38 between the discharge port 3102 and the guide pipe 36. When it is necessary to suck up material, the feed switch 35 is opened and the solenoid valve 38 is closed at the same time. The piston of the metering cylinder 32 moves upward, and the raw material enters the metering cylinder from the feeding pipe through the feeding channel. When it is necessary to inject the raw material from the metering cylinder into the mixing mechanism, the feed switch 35 is closed and the solenoid valve 38 is opened at the same time. The piston of the metering cylinder 32 moves downward, and the metering cylinder injects the raw material in it into the mixing mechanism through the discharge port 3102 and the guide pipe. The metering injection of raw material is achieved by the cooperation of the feed switch 35, the solenoid valve 38 and the piston drive mechanism 33, which perfectly replaces the scheme of using a switching valve and has the advantages of simple structure, fast response and low cost.

[0023] In this embodiment, the feeding channel 3101 includes a first feeding channel 31011 and a second feeding channel 31012, which are interconnected. The center of the first feeding channel 31011 and the center line of the second feeding channel 31012 are perpendicular to each other. A piston connection hole 31013 is provided at the intersection of the first feeding channel 31011 and the second feeding channel 31012. The feeding switch 35 includes a switching piston 351 and a switching driver 352 for driving the switching piston 351. The switching piston 351 is slidably and sealingly connected to the piston connection hole 31013, so that the switching piston 351 can connect or disconnect the first feeding channel 31011 and the second feeding channel 31012. The end of the second feeding channel 31012 is interconnected with the discharge port 3102 and the bypass port 3103. The beginning of the first feeding channel 31011 is connected to the feeding pipe 34. The above design facilitates the installation and debugging of the switch piston 351.

[0024] For ease of maintenance, an inspection port 31014 is connected to the first feed channel 31011, and a sealing plug 37 is detachably connected to the inspection port 31014.

[0025] In this embodiment, the switch driver 352 is a cylinder mounted on the frame 1.

The guide rod 331 is connected to the frame 1. The lifting seat 332 is slidably connected to the guide rod 331 in a vertical direction. The lifting nut 334 is connected to the lifting seat 332. The lifting motor 335 is connected to the frame 1. The lifting screw 333 is connected to the output end of the lifting motor 335. The lifting screw 333 and the lifting nut 334 are directly threaded together. The lifting motor 335 drives the lifting screw 333 to rotate, thereby driving the lifting seat 332 to rise and fall along the guide rod 331. A connecting rod is provided between the lifting seat 332 and the piston of the metering cylinder 32.

[0027] In this embodiment, the mixing mechanism 2 includes a mixing cylinder 21, a stirring shaft 22, and a stirring drive motor 23. The mixing cylinder 21 is connected to the frame 1, and the stirring drive motor 23 is connected above the mixing cylinder 21. The stirring shaft 22 is connected to the output shaft of the stirring drive motor 23 and extends into the mixing cylinder 21. The bottom of the mixing cylinder 21 is provided with a connecting plate 24, and the connecting plate 24 is provided with a feed inlet 240 that connects one-to-one with the guide pipe 36 of each of the raw material feeding mechanisms 3. The feed inlet 240 communicates with the inner cavity of the mixing cylinder 21. The mixing mechanism uses the stirring drive motor 23 to drive the stirring shaft 22 to rotate, thereby mixing the raw materials entering the mixing cylinder 21 evenly.

[0028] In this embodiment, an electromagnetic control valve 25 is provided on the connecting plate 24 to control the amount of raw materials entering the mixing cylinder 21 from the feed inlet 240. By controlling the amount of raw materials entering the mixing cylinder 21 through the electromagnetic control valve 25, precise control of the mixing ratio can be achieved.

[0029] In this embodiment, the upper part of the mixing cylinder 21 is provided with a discharge nozzle 26 that communicates with the inner cavity of the mixing cylinder 21, so as to facilitate the output of uniformly mixed raw materials.
