[0072] A powder material feeding method, using the above-mentioned powder material feeding device, comprises the following steps:

[0073] S1. After the system displays that the target package material weight is insufficient and confirms the weight M1 to be replenished, the refill hopper 1-16 is lowered to the designated position;

[0074] S2, the pressing cylinder 2-2 presses down the measuring bucket 3-13, and the pressing cylinder 2-2 is connected to the measuring bucket 3-13 under the action of the push-turn mechanism and the flip mechanism;

[0075] S3, the metering mechanism starts working, and after the weight of the material to be replenished is calculated by the metering mechanism, M2=M1, the metering mechanism stops working;

[0076] S4, close the bottom of the pressing cylinder 2-2 and the top of the measuring bucket 3-13 through the push-turn mechanism and the flip mechanism, and the pressing mechanism lifts the pressing cylinder 2-2;

[0077] S5, the rotating mechanism rotates the measuring hopper 3-13 to the designated pouring position above the feeding hopper 1-16, the flipping mechanism opens the top of the measuring hopper 3-13, and the metering mechanism starts to restart, and all the materials in the measuring hopper 3-13 are completely poured from the top of the measuring hopper 3-13 into the feeding hopper;

[0078] S6. After the feeding is completed, the feeding part 1, the feeding part 2 and the pouring part 3 all return to their initial positions.

[0079] The various steps of the above-mentioned feeding method are as follows:

[0080] In step S1, the lifting mechanism of the feeding hopper 1-16 can raise and lower the feeding hopper 1-16. In the initial position, the feeding hopper 1-16 lifting mechanism is parked at the top, the downward pressure cylinder 2-2 is raised, the upper opening and closing valve 2-9 is closed, and the lower opening and closing valve 3-17 of the material discharging section 3 is also closed, preventing material from the feeding hopper from entering the measuring hopper. The measuring hopper 3-13 and the downward pressure cylinder 2-2 are aligned, allowing powder material to enter the measuring hopper 3-13 from the feeding hopper 2-1 more effectively and accurately. The piston 3-14 is also at the uppermost position. When material arrives and stops at the designated position, the system indicates that the weight of the material package is insufficient and that the weight of the material required is M1. The lifting frame 1-1 lowers the feeding hopper 3-16 to the designated position. The system here can be completed by the commonly used material bag weight monitoring system on the market. Lowering the feeding hopper 3-16 to the designated position in advance facilitates timely refilling, saving working time and improving work efficiency.

[0081] In the above step S2, after completing step S1, the downward pressure cylinder 2-3 drives the lower opening and closing valve 3-17 pressed down by the downward pressure cylinder 2-2, and the upper opening and closing valve 2-9 and the lower opening and closing valve 3-17 rotate to the open state, so that the downward pressure cylinder 2-2 and the measuring bucket 3-13 are in a connected state.

[0082] In step S3 above, after step S2 is completed, the hopper motor 3-9 begins to rotate, and the piston 3-14 descends. The system calculates the required material replenishment weight M2 = M1 based on the number of revolutions of the hopper motor 3-9 and the lead of the screw 3-11. The hopper motor 3-9 then stops rotating. When the required replenishment weight is reached, the hopper motor 3-9 is promptly stopped to improve replenishment accuracy.

[0083] In the above step S4, after completing step S3, the upper opening and closing valve 2-9 and the lower opening and closing valve 3-17 are both turned to the closed state, and the pressing cylinder 2-3 lifts the pressing cylinder 2-2 to facilitate the rotation of the measuring bucket 3-13 and the discharge of the material in the measuring bucket into the feeding hopper.

[0084] In the above step S5, after completing step S4, the swing arm motor 3-3 drives the rotating swing arm 3-2 to rotate to the specified position above the feeding hopper 1-16, the rotating cylinder I3-4 rotates and drives the measuring hopper 3-13 to rotate to the pouring position, the rotating cylinder II3-16 rotates to open the lower opening and closing valve 3-17, and pours the material into the feeding hopper 1-16. At the same time, the measuring hopper motor 3-9 drives the screw 3-11 to rotate, so that the piston 3-14 moves upward until it reaches the top of the measuring hopper 3-13, and all the materials are poured into the feeding hopper 1-16.

[0085] In the above step S6, after step S5 is completed and the feeding is completed, the feeding part 1, the feeding part 2 and the pouring part 3 all return to their initial positions.

[0086] In summary, the specific beneficial effects of this embodiment are:

[0087] 1. In this embodiment, the position of the feeding hopper 1-16 is adjusted by the lifting mechanism. The feeding hopper 1-16 is adjusted to the corresponding position, which facilitates the adjustment of the position of the pouring device for feeding, avoids manual adjustment, and is simple to operate.

[0088] 2. In this embodiment, the metering mechanism can measure the mass of the material to be replenished and can automatically replenish the material with high accuracy, without the need for manual weighing, thus avoiding errors.

[0089] 3. In this embodiment, the pressing mechanism controls the pressing cylinder 2-2, the rotating mechanism controls the opening and closing of the pressing cylinder 2-2, and the flip mechanism controls the opening and closing of the measuring hopper, so that the feeding hopper 2-1 can be accurately connected with the measuring hopper 3-13, and the material can be accurately entered into the measuring hopper, thereby improving the accuracy and efficiency of feeding.

[0090] 4. In this embodiment, the position of the rotating measuring hopper is controlled by the rotating mechanism, so that the position of the measuring hopper can be quickly adjusted to align with the feeding hopper, thereby quickly completing the feeding work.
