wherein, the discharging port 32 is provided with a discharging control switch;

wherein, the basic material weighing hopper 11 is fixedly connected with the first weighing sensor 13, and the filling material weighing hopper 16 is fixedly connected with the second weighing sensor 17. The weight of the metal powder in the base material weighing hopper 11 and the filler weighing hopper 16 can be measured by the first weighing sensor 13 and the second weighing sensor 17, respectively.

When weighing metal powder, metal powder gets into feed chute 1 from pan feeding end 101 of feed chute 1, then flows to discharge end 102 from feed chute 1, enters into basic material weighing hopper 11 from discharge end 102, after the flow on the feed chute 1, but metal powder evenly distributed on feed chute 1, metal powder's flow velocity and flow time have the corresponding law of removal, can close the process that metal powder got into in basic material weighing hopper 11 through blanking control assembly when metal powder's weight is close required weight according to flow time.

The base material weighing hopper 11 weighs the non-ferrous metal powder to be weighed by the required basic amount, the required basic amount is close to the weight of the non-ferrous metal to be filled, at the moment, one end of the feeding chute 1 can be kept at a quick discharging speed, the non-ferrous metal weight in the base material weighing hopper 11 can be infinitely close to the required filling weight by slowing down the discharging speed of the metal powder when the weight of the non-ferrous metal to be filled is connected, and the filling can be stopped when the weight of the metal powder in the base material weighing hopper 11 is quickly collided with the basic weight.

At this time, the discharge cover 12 in the base material weighing hopper 11 may be opened, and the discharge cover 12 at the first discharge port 112 is changed from the closed state to the open state, so that the metal powder in the base material weighing hopper 11 falls into the filler weighing hopper 16. After the basic material weighing hopper 11 is collected, the metal powder falling into the filler weighing hopper 16 is always kept at a stable placing position, and at the moment, the output parameters of the weighing sensor and the corresponding positions are subjected to progress debugging to keep stable weighing parameters, so that the weighing precision of each time is kept consistent.

After the base material weighing hopper 11 is opened, the metal powder in the base material weighing hopper 11 is completely poured into the filling material weighing hopper 16, at this time, the opening state of the base material weighing hopper 11 can be kept, and a small amount of metal powder is added into the filling material weighing hopper 16 by the fine feeding mechanism 3, so that the weight of the metal powder in the filling material weighing hopper 16 reaches the required weight. The method of adding a small amount of metal powder can improve the weighing precision of the metal powder, the total amount of the metal powder needing to be added in a small amount is small, and the required waiting time is short.

The feeding pipe 35 passes through the bottom of the feeding chute 1 and is arranged below the feeding chute 1, when the metal powder flows from the feeding end 101 to the discharging end 102 of the feeding chute 1, the feeding pipe 35 is filled at first, and the metal powder cannot directly fall into the weighing hopper due to the blocking of the discharging control switch at the discharging port 32. Instead, the metal powder is stored in the feed pipe 35 and moved into the weighing hopper after the control switch is turned on.

Example 3

Referring to fig. 4 and 5, further, the discharging control switch includes a striker plate 33 and a first control push rod 34;
