[0019] The following is combined with Figure 1-4 This application is described in further detail.

[0020] The present application embodiment discloses a raw material metering device. Figure 1-4 A raw material metering device includes a metering bin 1, which is a cylindrical structure. A weighing sensor 4 is fixedly installed on the bottom middle inner wall of the metering bin 1, and a carrying plate 5 is fixedly installed on the top outer wall of the weighing sensor 4 by bolts. A feed box 3 is fixedly connected to the outer wall of the metering bin 1. The inner cavity of the feed box 3 is connected to the inside of the metering bin 1, and the feed box 3 is located above the carrying plate 5. A feeding mechanism is installed on the outer wall of the feed box 3. A fixing frame 11 is fixedly connected to the outer wall of the metering bin 1 corresponding to the feed box 3. A controller 12 is detachably installed on the outer wall of the fixing frame 11. The controller 12 is a microprocessor and is connected to the weighing sensor 4 through a data line.

[0021] The feeding mechanism includes a rotating shaft 8 rotatably connected to the inner cavity of the feeding box 3, and the outer wall of the rotating shaft 8 is fixedly connected to a threaded conveying blade 9, and the outer wall edge of the threaded conveying blade 9 away from the rotating shaft 8 is in contact with the inner wall of the feeding box 3.

[0022] The feeding mechanism also includes a servo motor 10 fixedly mounted on the outer wall of the feeding box 3 away from the metering bin 1 . The output shaft end of the servo motor 10 passes through the feeding box 3 and is fixedly connected to one end of the rotating shaft 8 .

[0023] A discharge port 7 is provided on the bottom outer wall of the feed box 3 at one end away from the metering bin 1 . The discharge port 7 is communicated with the inner cavity of the feed box 3 , and the raw materials in the feed box 3 are discharged through the discharge port 7 .

[0024] A feed port 2 is formed on the outer wall of the metering bin 1 above the carrier plate 5 , and a feed hopper 13 is fixedly connected to the inner wall of the feed port 2 . The feed hopper 13 is convenient for feeding raw materials so that the raw materials enter the metering bin 1 through the feed port 2 .

[0025] A hollow sealing ring 6 is bonded to the edge of the outer wall of the carrying plate 5, and the hollow sealing ring 6 fits tightly against the inner wall of the metering bin 1. The hollow sealing ring 6 has a certain elasticity and softness. When the outer wall of the edge of the carrying plate 5 and the inner wall of the metering bin 1 cooperate to squeeze the hollow sealing ring 6, its softness causes the hollow sealing ring 6 to deform, thereby generating elastic force. The elastic force generated by the hollow sealing ring 6 makes its outer wall always fit tightly against the inner wall of the metering bin 1, forming a good soft seal to prevent the raw materials from leaking downward from the carrying plate 5.

[0026] The implementation principle of a raw material metering device in an embodiment of the present application is as follows: when in use, the raw material is added into the metering bin 1 through the feed hopper 13 and the feed port 2, and the user sets the required raw material metering value through the controller 12. When the raw material enters the metering bin 1 through the feed port 2, it will fall onto the surface of the carrier plate 5. At this time, the weighing sensor 4 located in the middle of the bottom of the carrier plate 5 monitors the weight of the raw material in the metering bin 1 in real time, and sends the weight signal to the controller 12 through the data line. The controller 12 compares the received weight signal with the preset metering value. When the preset metering value is reached, the servo motor 10 is controlled to start through the feeding mechanism, and the output shaft of the servo motor 10 drives the rotating shaft 8 to rotate. When the rotating shaft 8 rotates, it will drive the threaded conveying blades 9 to rotate, and the threaded conveying blades 9 will evenly discharge the measured raw materials from the discharge port 7.
