As shown in fig. 16, when the second feeding shaft 4 moves up to the position of the groove 41 corresponding to the ball head of the first feeding shaft 3, the raw material can fall from the groove 41 and then be discharged through the first discharging hole 211 and the second discharging hole 212. Because the size of the groove 41 is smaller, the raw materials falling through the groove 41 are also smaller, so that the once blanking amount is smaller, and the purpose of fine blanking by controlling the discharging amount is realized.
In order to complete the present embodiment, as shown in fig. 8 and 9, a plurality of baffle blocks 42 are disposed on the outer diameter of the second feeding shaft 4 along the axial direction thereof, and in this embodiment, the main body portion of the second feeding shaft 4 includes a thin rod and a thick rod, where the thick rod and the thin rod are based on the view, the diameter of the upper position of the second feeding shaft 4 is larger, the thick rod, the diameter of the lower position is smaller, and the thin rod. As shown in fig. 12, the outer diameter of the thick rod part is slightly smaller than the inner diameter of the first feeding shaft 3, so that the second feeding shaft 4 can move up and down; the baffle block 42 is obliquely arranged on the thin rod and extends towards the discharge hole 21, and as shown in fig. 12 and 13, the baffle block 42 and the surface of the second feeding shaft 4 enclose a parallelogram, and an included angle beta between the bottom edge of the parallelogram and the second feeding shaft 4 is an acute angle. As shown in fig. 12, a gap is still remained between the material blocking block 42 and the inner wall of the first feeding shaft 3, when the raw material enters the first feeding shaft 3, the raw material is dispersed in the gap between the first feeding shaft 3 and the second feeding shaft 4, and the material blocking block 42 can prevent the raw material from being fully accumulated at the bottom, so that too much one-time discharging is avoided. This structure further reduces the amount of the raw material falling from the groove 41 when the second feeding shaft 4 is moved upward, and more facilitates the realization of fine blanking.
5. A cover 13;
As shown in fig. 1, a cover 13 is fixedly arranged on the discharge hopper 2, in this embodiment, the cover 13 includes a first cover 131 and a second cover 132, the opening of the first cover 131 is fixedly arranged above the discharge hopper 2 downward, and in this embodiment, the first cover 131 and the second cover are in threaded fixation; the second cover 132 is a cylindrical structure, covers the position of the spring 7 on the second feeding shaft 4, the second feeding shaft 4 extends out from the upper part of the second cover 132, and the second feeding shaft 4 is movably connected with the cover 13, wherein the movable connection means that the inner diameter of the second cover 132 is equal to or slightly larger than the outer diameter of the limiting disc 6, so that the upper ends of the limiting disc 6 and the second feeding shaft 4 can move up and down relative to the second cover 132. The motor 11 is fixedly arranged on the inner wall of the first cover body 131, and the motor 11 and the belt 12 are positioned between the first cover body 131 and the discharge hopper 2.

Of course, the position of the feeding hopper 5 may also be set on the side wall of the first cover 131 or the side wall of the discharging hopper 2, so long as discharging can be achieved.
When the balance and the vessel are placed under the discharge port 21 of the device in the use of the embodiment, raw materials fall into the feeding section 22 and the spiral groove 31 of the discharge hopper 2 after being put in from the feed hopper 5, and when the first feeding shaft 3 does not rotate, the raw materials cannot fall between the first feeding shaft 3 and the discharge section 23 of the discharge hopper 2 due to the fact that the outer diameter of the first feeding shaft 3 is equal to the inner diameter of the discharge section 23 of the discharge hopper 2, see fig. 12.
During blanking, the motor 11 drives the first feeding shaft 3 to rotate, and raw materials in the spiral groove 31 on the first feeding shaft 3 are pushed to be conveyed downwards and are blanked through the first discharging hole 211. The opening 32 on the first feeding shaft 3 can enable raw materials to enter the first feeding shaft 3, and fine blanking is achieved through the second feeding shaft 4. The pushing plate 33 on the first feeding shaft 3 can play a role of pushing materials, when the first feeding shaft 3 rotates, the pushing plate 33 rotates along with the first feeding shaft, and the pushing plate 33 can push raw materials into the spiral groove 31 and the opening 32.
Under normal conditions, as shown in fig. 12, the outer wall of the thin rod of the second feeding shaft 4 is in contact with the ball head position of the first feeding shaft 3, the second feeding shaft 4 cannot discharge, when discharging is needed, the second feeding shaft 4 is lifted upwards, as shown in fig. 16, when the groove 41 corresponds to the ball head position of the first feeding shaft 3, raw materials can fall from the groove 41, and then are discharged through the first discharging hole 211 and the second discharging hole 212. It should be noted that, as shown in fig. 4, 10, 11, and 12, the bottom of the discharge hopper 2 is in a hollow structure, the bottom end of the second feeding shaft 4 abuts against the bottom of the discharge hopper 2, and a certain distance is left between the first feeding shaft 3 and the bottom of the discharge hopper 2.
When the blanking amount of the first feeding shaft 3 is more than that of the second feeding shaft 4, if 50.8g of the blanking amount is required to be blanked in practical application, 50g of the blanking amount is blanked through the first feeding shaft 3, and the rest 0.8g of the blanking amount is blanked through the second feeding shaft 4, so that the first feeding shaft 3 does not rotate any more during the fine blanking. Since the second feeding shaft 4 is fed a small amount each time, by observing the balance value located below the bracket 1, when the value reaches 0.8g, the second feeding shaft 4 is released, the second feeding shaft 4 moves downwards under the action of the spring 7, and the state in fig. 12 is restored, and the feeding is not performed any more. According to the embodiment, fine blanking is realized by controlling the discharging amount, and pollution caused by too long exposure time of raw materials in the environment in a weighing link is avoided.
