Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4This utility model provides a technical solution: including a base 1, an annular frame 2 installed on the base 1, a support column 22 fixed between the outer side of the annular frame 2 and the base 1, a feed pipe 21 fixed at equal intervals on the upper side wall of the annular frame 2, an annular plate 63 rotatably connected inside the annular frame 2 and below the end of the feed pipe 21, a weighing hopper 4 installed on the annular plate 63, a mixing rod 61 rotatably connected inside the weighing hopper 4, a transmission assembly provided between the mixing rod 61 and the inner side wall of the annular frame 2, a discharge pipe 41 fixed at the bottom of the weighing hopper 4, and a solenoid valve 5 installed on both the discharge pipe 41 and the feed pipe 21.

[0016] The transmission assembly includes an end plate 6 and an annular plate 63. The end plate 6 is fixed to the upper end of the weighing hopper 4. The upper end of the mixing rod 61 extends out of the end plate 6 and is fixed with a transmission gear 62. The annular plate 63 is fixed inside the annular frame 2 and is aligned with the transmission gear 62. A transmission toothed plate 64 is fixed inside the annular plate 63. The transmission toothed plate 64 and the transmission gear 62 mesh. A drive shaft 11 is rotatably connected to the upper end of the base 1. A stepper motor that drives the drive shaft 11 to rotate is fixed inside the base 1. A connecting plate 12 is fixed to the upper end of the drive shaft 11 and is fixed inside the rotating plate 3.

[0017] An upper ring plate 42 is fixed on the outside of the weighing hopper 4 and above the rotating plate 3. A pressure sensor 43 is installed between the upper ring plate 42 and the rotating plate 3. A lower ring plate 44 is fixed on the outside of the weighing hopper 4 and below the rotating plate 3. Guide posts 45 are fixed at equal intervals on the upper end of the lower ring plate 44. A guide groove 31 is opened at the bottom of the rotating plate 3 and at the position corresponding to the guide post 45. The feed pipe 21 corresponds to the weighing hopper 4. An extension hopper 46 is fixed on the outer side of the upper end of the weighing hopper 4. The extension hopper 46 is vertically aligned with the opening at the end of the feed pipe 21.

[0018] Working principle: First, the entire device is connected to an external power source. Then, a stepper motor drives the drive shaft 11 and the rotating plate 3 to rotate, causing the same weighing hopper 4 to pass through different feed pipes 21 in sequence. During the feeding operation using the feed pipe 21, as more and more raw materials are loaded, the squeezing force on the pressure sensor 43 also increases. Therefore, only pressure detection and the on / off control of the solenoid valve 5 are needed to achieve accurate weighing and feeding ratios, realizing continuous feeding and greatly improving work efficiency. Furthermore, during the rotation of the rotating plate 3, the meshing of the transmission gear 62 and the transmission toothed plate 64 allows the transmission gear 62 to roll on the transmission toothed plate 64, thereby driving the mixing rod 61 to rotate and stir the added raw materials. After unloading, no independent mixing operation is required, further improving work efficiency.
