[0033] A powder spiral discharge container is installed on the side of the sliding block 15 away from the U-shaped connecting plate 19. Two relatively arranged C-shaped plates 20 are fixedly connected to the side of the sliding block 15. The powder spiral discharge container is located between the two C-shaped plates 20. The powder spiral discharge container is detachably connected to the C-shaped plates 20 by bolts.

[0034] The powder spiral discharging container includes a powder holding tank body 3, a spiral rod 4 and a container adapter 5.

The top of the sliding block 15 is fixedly connected with a motor B13, and the output shaft sleeve of the motor B13 is fixedly provided with a gear B11, which is meshed with the gear A10. The motor B13 drives the rotating shaft 9 to rotate, and the rotating shaft 9 drives the spiral rod 4 to rotate during the rotation process. The spiral rod 4 can stir the powder in the powder holding tank body 3 during the rotation process.

[0035] A high-precision weighing sensor 2 is installed on the inner top of the L-shaped base 1, and the powder spiral discharging container is located above the high-precision weighing sensor 2. The four corners of the bottom of the L-shaped base 1 are equipped with horizontal adjustment feet 21. A windproof cover 22 is installed on the outside of the L-shaped base 1. The front side of the windproof cover 22 is provided with an opening. A windshield 25 is slidably connected to the top of the front side of the windshield 22.

The display screen 23 is located on the front side of the L-shaped base 1.

[0036] A container adapter 5 is inserted and fixed on the side of the powder holding tank body 3 at an angle, and the container adapter 5 is used to install a powder reagent bottle 6. The bottom of the powder holding tank body 3 is funnel-shaped, and a discharge port 24 is provided at the bottom of the powder holding tank body 3.

The collecting cylinder 7 is used to collect the powder that falls from the powder holding tank body 3 to avoid splashing of the powder during the falling process.

[0037] Working principle:

[0038] Start motor A12, which drives the screw 17 to rotate. During the rotation of the screw 17, the sliding sleeve 18 is driven to move downward. During the movement of the sliding sleeve 18, the U-shaped connecting plate 19 is driven to move downward along the vertical hole 16. During the movement of the U-shaped connecting plate 19, the sliding block 15 is driven to move downward. During the movement of the sliding block 15, the powder holding tank body 3 is driven to move downward until the discharge port 24 of the powder holding tank body 3 is aligned with the top of the collecting cylinder 7, and then the motor A12 is turned off.

[0039] The powder reagent bottle 6 is installed on the side of the powder holding tank body 3 through the container adapter 5, and the powder in the powder reagent bottle 6 enters the inside of the powder holding tank body 3. According to the weighed quantity, it is selected whether to remove the powder reagent bottle 6, and the motor B13 is started. The motor B13 drives the rotating shaft 9 to rotate through the cooperation of the gear A10 and the gear B11. The rotating shaft 9 drives the spiral rod 4 to rotate through the fixed plate 14 during the rotation process. The spiral rod 4 stirs the powder inside the powder holding tank body 3 during the rotation process, so that the powder falls evenly from the discharge port 24 to the high-precision The top of the high-precision weighing sensor 2 can be controlled by the motor B13 to control the rotation speed of the screw rod 4, thereby controlling the amount and speed of the powder falling. The collecting tube 7 can collect and gather the falling powder to ensure that the powder is concentrated on the top of the high-precision weighing sensor 2, thereby increasing the weight of the powder weighed by the high-precision weighing sensor 2. The value weighed by the high-precision weighing sensor 2 is displayed on the display screen 23. When the weight weighed by the high-precision weighing sensor 2 reaches the specified weighing value, the motor B13 is turned off, the collecting tube 7 is opened, and the powder is transferred. After the weighing is completed, the motor A12 is started to rotate in the opposite direction, thereby driving the powder holding tank 3 to reset.

[0040] Different types of powder holding tanks 3 can be replaced according to the weighing requirements of different powders. A solenoid valve can be set at the discharge port, and the switch can be controlled by the touch-screen PLC all-in-one machine to achieve controllable falling of the powder. Both motor A and motor B can be controlled and operated by the touch-screen PLC all-in-one machine.
