[0021] See also Figure 1-Figure 4 As shown, the utility model provides a technical solution:

[0022] A packaging device with automatic weighing includes a conveyor housing 6, a screening box 10 is provided at one end of the conveyor housing 6, an input port 9 is provided above the screening box 10, and an input channel 11 is connected between the input port 9 and the conveyor housing 6. The bottom of the input channel 11 is open and connected to the screening box 10, and a sieve plate 19 is fixedly provided in the input channel 11 between the input port 9 and the conveyor housing 6. The sieve plate 19 is inclined downward in the direction away from the input port 9, and the sieve plate 19 is densely covered with sieve holes. The top surface of the sieve plate 19 is rotatably connected to a plurality of rotating columns 21, and sealing plates 22 are symmetrically provided on both sides of the rotating columns 21. One side of the conveyor housing 6 is connected to an impurity collection box 2, and a screen 18 is provided between the conveyor housing 6 and the impurity collection box 2. The other side of the conveyor housing 6 is connected to a plurality of first air outlet pipes 7.

[0023] The Chinese herbal medicine slices are inputted onto the sieve plate 19 through the input port 9. The Chinese herbal medicine slices slide down the sieve plate 19 due to the influence of their own gravity, so that the Chinese herbal medicine slices that do not meet the requirements and the generated debris fall into the screening box 10. The air is blown out from the air outlet pipe 7 by the operation of the blower 5, blowing the sealing plate 22 to move, and the sealing plate 22 drives the rotating column 21 to rotate, so that the Chinese herbal medicine slices that fall on the top surface of the sieve plate 19 are fully screened.

[0024] In this embodiment, preferably, an active roller 13 and a driven roller 15 are provided in the conveyor housing 6, and a conveyor belt 16 is connected to the active roller 13 and the driven roller 15. A motor 12 for driving the active roller 13 to rotate is fixedly provided on one side of the conveyor housing 6, and the input end of the conveyor belt 16 extends to below the output port of the input channel 11.

[0025] The motor 12 drives the active roller 13 to rotate, the active roller 13 drives the driven roller 15 to rotate, and the driven roller 15 drives the conveyor belt 16 to move, thereby completing the conveying.

[0026] In this embodiment, preferably, baffles 17 are uniformly distributed on the outer surface of the conveyor belt 16 , and the baffles 17 are all arranged perpendicular to the transmission direction of the conveyor belt 16 .

[0027] A plurality of baffles 17 are provided on the outer surface of the conveyor belt 16 so that the Chinese herbal medicine slices passing through the sieve plate 19 are conveyed to the conveyor belt 16 .

[0028] In this embodiment, preferably, the end of the conveyor housing 6 away from the screening box 10 is connected to the discharge box 3, the output end of the conveyor belt 16 extends to the discharge box 3, and the bottom of the discharge box 3 is connected to the automatic weighing and packing box 4, and the conveyor housing 6, the screening box 10, the input channel 11, the discharge box 3 and the automatic weighing and packing box 4 are all arranged in the housing 1.

[0029] The Chinese herbal medicine slices are finally dropped into the discharge box 3 by the conveyor belt 16, and the discharge box 3 slowly drops the Chinese herbal medicine slices into the automatic weighing and packaging box 4 to complete weighing and packaging.

[0030] In this embodiment, preferably, a hair dryer 5 is fixedly connected to the inner wall of the housing 1 , an output end of the hair dryer 5 is fixedly connected to an air supply pipe 8 , and the first air outlet pipe 7 is communicated with the air supply pipe 8 .

[0031] The blower 5 operates to input wind into the first air outlet pipe 7 through the air supply pipe 8, and the first air outlet pipe 7 penetrates the connected conveyor housing 6, so that the first air outlet pipe 7 blows the wind onto the outer surface of the conveyor belt 16. The wind blown out by the first air outlet pipe 7 causes the screened Chinese herbal medicine slices to be separated from the fine impurities and debris again on the outer surface of the conveyor belt 16. The wind blown out by the first air outlet pipe 7 blows the fine impurities and debris carried by the Chinese herbal medicine slices away from the Chinese herbal medicine slices, and falls into the impurity collection box 2 through the screen 18, thereby completing the screening of high-quality Chinese herbal medicine slices.

[0032] In this embodiment, preferably, a plurality of second air outlet pipes 23 are connected to one side of the input channel 11 , and the second air outlet pipes 23 are all connected to the air supply pipe 8 .

[0033] The hair dryer 5 is used to input the wind into the second air outlet pipe 23 through the air supply pipe 8. The second air outlet pipe 23 passes through the connected input channel 11, so that the second air outlet pipe 23 blows the wind on the outer surface of the sealing plate 22, so that the sealing plate 22 drives the rotating column 21 to rotate. The sealing plate 22 fixedly connected to the outer surface of the rotating column 21 fully stirs the Chinese herbal medicine pieces falling on the top surface of the sieve plate 19, so that the inferior Chinese herbal medicine pieces and the debris pass through the sieve plate 19 and fall into the screening box 10, completing the first screening.

[0034] Working principle:

[0035] The packing machine with automatic weighing of this embodiment is used. When the Chinese medicine pieces are inputted onto the sieve plate 19 through the input port 9, the Chinese medicine pieces slide down along the sieve plate 19 under the influence of their own gravity, so that the Chinese medicine pieces that do not meet the requirements and the generated debris fall into the screening box 10. The air is blown out from the air outlet pipe 7 by the operation of the blower 5, blowing the sealing plate 22 to move, and the sealing plate 22 drives the rotating column 21 to rotate, so that the Chinese medicine pieces falling on the top surface of the sieve plate 19 are fully screened, and the active roller 13 is driven by the motor 12 to rotate, and the active roller 13 drives the driven roller 15 to rotate, and the driven roller 15 drives the conveyor belt 16 to move, completing the conveying, and the baffle 17 on the top surface of the conveyor belt 16 is provided, so that the Chinese medicine pieces that have passed the sieve plate 19 are transported to the conveyor belt 16, and the Chinese medicine pieces are finally dropped into the discharge box 3 by the conveyor belt 16, and the discharge box 3 slowly drops the Chinese medicine pieces into the automatic weighing and packaging box 4, completing the weighing and packaging. The air is blown out of the first air pipe 7 and then into the second air outlet duct 23, and the air blown out from the first air pipe 7 blows the fine impurities and debris carried by the Chinese medicine slices away from the Chinese medicine slices, and falls into the impurity collection box 2 through the screen 18, thereby completing the screening of high-quality Chinese medicine slices.
