And as shown in fig. 4 and 5, the medicine weighing passage 3 includes a common medicine weighing passage 301, a coarse material weighing passage 302, and a fine material weighing passage 304.
The medicine pouring slide way 2 is arranged at the bottom of the medicine containing box 1, and the bottom of the medicine pouring slide way 2 is connected with the front end of the common medicine weighing channel 301. The top of the medicine pouring slide way 2 is provided with a gate plate (not shown in the figure), a horizontally extending gap is reserved between the gate plate and the medicine pouring slide way 2, the width of the gap is matched with the medicine, the medicine can only flow into the medicine pouring slide way 2 from the medicine charging box 1 through the gap, only one layer of medicine is ensured to pass through the gate plate, and therefore only one layer of medicine enters the common medicine weighing channel 301 from the medicine charging box 1 through the medicine pouring slide way 2.
The rough material weighing channel 302 is arranged at the bottom of the end of the common medicine weighing channel 301, and the rough material weighing channel 302 is in the shape of a disc with an open end, and the open end of the rough material weighing channel 302 is positioned above the weighing device 5. The rough weighing channel 302 can temporarily store a large amount of medicine, and make the medicine quickly fall into the weighing device 5 through the opening at the end of the rough weighing channel 302.
As shown in fig. 3, a fine weighing bin 303 is disposed at the end of the common weighing channel 301, and a small amount of medicament can be temporarily stored in the fine weighing bin 303. The front end of the fine weighing channel 304 is connected with the fine weighing bin, and the tail end of the fine weighing channel extends out of the upper part of the coarse weighing channel 302 and extends to the upper part of the weighing device 5. The shape and area of the cross section of the fine material passage 304 are matched with the medicament, so that the medicament slowly passes through the fine material passage 304 and falls into the weighing device 5 one by one.
The bottom of the medicine weighing channel 3 is provided with a fine weighing vibrator 6 and a coarse weighing vibrator 7. The fine weighing vibrator 6 is connected with the bottom of the common medicine weighing channel 301, the coarse weighing vibrator 7 is connected with the bottom of the coarse weighing channel 302, and the fine weighing vibrator 6 and the coarse weighing vibrator 7 provide forward power for the medicine through vibration.
The baffle 4 is in a frame shape, the bottom of the baffle 4 is arranged at the tail end of the rough material weighing channel 302, and the baffle 4 can be controlled to move up and down through a cylinder or other control devices, so that the tail end of the rough material weighing channel 302 is controlled to be opened or blocked.
When the automatic medicine weighing device of the embodiment is used for weighing and quantifying the medicines, a plurality of medicines are discharged at the same time through rough weighing, so that quick medicine weighing is ensured; and when the weight of the medicament on the weighing device 5 reaches a preset value, the medicament is weighed accurately, so that the medicament is discharged from a single particle, finally, the weight of the medicament on the weighing device 5 slowly reaches a required value, and the weighing accuracy is ensured.
Specifically, as shown in fig. 4, during rough weighing, the baffle 4 moves downward, and the bottom end of the baffle 4 moves to below the end of the rough weighing channel 302, so that the end of the rough weighing channel 302 is opened. At this time, the fine weighing vibrator 6 and the coarse weighing vibrator 7 both vibrate rapidly, the coarse weighing channel 302 serves as a main discharge port, and the fine weighing channel 304 serves as a secondary discharge port, so that a large amount of the medicine falls into the weighing device 5 rapidly.

Example 2
As shown in fig. 6 and 7, the present embodiment is different from embodiment 1 in that the baffle 4 includes a left baffle 401 and a right baffle 402, and the left baffle 401 and the right baffle 402 are horizontally moved under the control of a cylinder or other control means to control the end of the rough weigh channel 302 to be opened or blocked.
As shown in fig. 6, in rough weighing, the left baffle 401 and the right baffle 402 move away from each other, and a gap is left between the left baffle 401 and the right baffle 402, so that the end of the rough weighing channel 302 is open. At this time, the fine weighing vibrator 6 and the coarse weighing vibrator 7 both vibrate rapidly, the coarse weighing channel 302 serves as a main discharge port, and the fine weighing channel 304 serves as a secondary discharge port, so that a large amount of the medicine falls into the weighing device 5 rapidly.
As shown in fig. 7, during fine weighing, the left baffle 401 and the right baffle 402 move close to each other, and the left baffle 401 and the right baffle 402 are close to each other without a gap in the middle, so as to block the discharge hole of the coarse weighing channel 302. At this time, only the fine material channel 304 is used as a discharge port, and the fine vibrator 6 vibrates to slowly drop the medicines into the weighing device 5 one by one. Preferably, a precise discharging groove is arranged on one side of each of the left baffle 401 and the right baffle 402 close to each other. During fine weighing, the fine weighing channel 304 passes through the fine weighing discharging channel, and the medicament falls into the weighing device 5 after passing through the fine weighing discharging channel. The shape and the size of the fine weighing discharging trough are matched with the medicament, and the medicament passes through the fine weighing discharging trough one by one, so that the medicament can fall into the weighing device 5 one by one.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
