Description

Technical Field

[0001] The utility model belongs to the technical field of traditional Chinese medicine production, and particularly relates to a weighing device for traditional Chinese medicine formula granules. Background Art

[0002] Traditional Chinese medicine formula granules are granules made by processing traditional Chinese medicine decoction pieces, extracting and concentrating them, and then packaging them in portions. They have a small dosage, are convenient for storage and transportation, maintain the medicinal properties of traditional Chinese medicine decoction pieces, eliminate the trouble of patients' decocting, and are more convenient for taking. The weighing of traditional Chinese medicine formula granules is an important step, especially in pharmaceutical production and clinical applications;

[0003] In the prior art, there are manual weighing and packaging methods and mechanical weighing and packaging methods for weighing traditional Chinese medicine formula granules. For the manual weighing and packaging method, it has high requirements for the experience of weighing personnel and low weighing efficiency, and is only applicable to a small amount of packaging. If batch weighing and packaging are required, it is difficult to achieve; for the mechanical weighing and packaging method, generally a weighing sensor is used to weigh traditional Chinese medicine formula granules, and after weighing, it is directly packaged. If there are impurities on the weighing pan or other unexpected situations cause incorrect weighing, it is difficult for workers to find in time, which will lead to a decrease in the qualified rate of products. Therefore, the existing weighing method for traditional Chinese medicine formula granules needs to be improved. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a weighing device for traditional Chinese medicine formula granules aiming at the above existing technical problems. This weighing device weighs continuously twice and compares, and then packs after confirming that the weight is correct, so that workers can quickly find weighing errors and improve the qualified rate of products.

[0005] In view of this, the utility model provides a weighing device for traditional Chinese medicine formula granules, including:

[0006] A storage tank, which can store materials, discharge materials, and control the discharge amount of materials;

[0007] A first-stage receiving tray, which can receive the materials discharged from the storage tank and discharge the materials on it;

[0008] A second-stage receiving tray, which can receive the materials discharged from the first-stage receiving tray and discharge the materials on it;

[0009] A first weighing module, which is used to weigh the storage tank;

[0010] A second weighing module, which is used to weigh the first-stage receiving tray.

[0011] In this technical solution, sufficient materials are stored in the storage tank. Each time the storage tank discharges a preset weight of materials into the first-level receiving tray, weighing module one can measure the weight of the storage tank before and after discharging and calculate the difference value. Weighing module two can measure the weight of the first-level receiving tray before and after receiving materials and calculate the difference value. Then, the difference value before and after the storage tank discharges and the difference value before and after the first-level receiving tray receives materials are compared manually or by the processing module. If the two values are the same, the first-level receiving tray discharges the materials onto the second-level receiving tray, and the second-level receiving tray discharges the materials into the packaging bag for loading. If the two values are different, the first-level receiving tray stops discharging, indicating a weighing error.

[0012] In the above technical solution, further, a material dropping groove is vertically formed on the first-level receiving tray. A swing plate is provided in the material dropping groove. When the swing plate is in the horizontal position, it can close the material dropping groove, and when the swing plate swings downward, it can open the material dropping groove. The second-level receiving tray is arranged below the first-level receiving tray.

[0013] In the above technical solution, further, there are two swing plates, and the two swing plates are symmetrically arranged on both sides of the material dropping groove and can swing symmetrically in the material dropping groove.

[0014] In the above technical solution, further, the notch of the material dropping groove is higher than the upper surface of the swing plate when it is in the horizontal position.

[0015] In the above technical solution, further, a motor for driving the swing plate to swing is provided on the first-level receiving tray.

[0016] In the above technical solution, further, a fixed seat is provided below the second-level receiving tray. One side of the ground of the second-level receiving tray is rotatably connected to the top of the fixed seat. An air cylinder is provided on one side of the fixed seat, and the air cylinder is used to drive the second-level receiving tray to swing up and down with the rotation connection point as the fulcrum.

[0017] In the above technical solution, further, a surrounding plate is provided on the upper surface of the second-level receiving tray. The surrounding plate is arranged around the second-level receiving tray, and the surrounding plate has an opening, and the opening is located at the bottom of the second-level receiving tray when the second-level receiving tray is in an inclined state.

[0018] In the above technical solution, further, a base is further included, and the base is used to carry the storage tank, the first-level receiving tray, the second-level receiving tray, weighing module one, and weighing module two.

[0019] The beneficial effects of the present utility model are:

[0020] 1. Through the cooperation of the storage tank, the first receiving tray, the second receiving tray, the first weighing module, and the second weighing module, the material is discharged from the storage tank onto the first receiving tray, and then from the first receiving tray onto the second receiving tray. The first weighing module and the second weighing module respectively measure the reduced weight of the storage tank and the increased weight of the first receiving tray, and then compare the two values to achieve accurate weighing of the material. At the same time, when there is a weighing error, the second receiving tray stops discharging, and the material will not be packaged, which can prevent products with unqualified weights from being mixed into qualified products, thereby improving the qualification rate of products.

[0021] 2. By designing the process of discharging from the first receiving tray and receiving in the second receiving tray as the cooperation of the falling material chute and the swing plate, and setting the second receiving tray below the first receiving tray. When the swing plate closes the falling material chute, the surface of the swing plate serves as the receiving area of the first receiving tray to receive the material discharged from the storage tank. When the swing plate opens the falling material chute, the swing plate is in an inclined state, and the material on the surface of the swing plate can fall onto the second receiving tray under the action of gravity. In this way, without setting other pushing structures, the transfer of the material from the first receiving tray to the second receiving tray can be realized, with a clever structure and low use cost.

[0022] 3. By designing the second receiving tray to cooperate with the fixed seat and the air cylinder, driving the second receiving tray to swing through the air cylinder can make the second receiving tray switch between the receiving state and the discharging state, with simple operation and a clever structure.

[0034] Embodiment 1

[0035] This embodiment provides a weighing device for traditional Chinese medicine formula granules, including: base 12, storage tank 1, first-stage receiving tray 2, second-stage receiving tray 3, first weighing module 4, second weighing module 5

[0036] Please refer to Figure 1 , the storage tank 1 has a storage chamber inside for storing materials, the lower end of the storage tank 1 is provided with a discharge port for discharging the materials in the storage chamber, and an electromagnetic valve for controlling the opening and closing of the discharge port is provided at the bottom of the storage tank 1, so as to control the discharge amount of the materials in the storage chamber;

[0037] The first-level material receiving tray 2 is located below the discharge port of the storage tank 1 and can receive the materials discharged from the storage tank 1. The first-level material receiving tray 2 can discharge the materials thereon. The discharging process of the first-level material receiving tray 2 can generally be realized through manual control;

[0038] The second-level material receiving tray 3 can receive the materials discharged from the first-level material receiving tray 2. The second-level material receiving tray 3 can discharge the materials thereon. The materials discharged from the second-level material receiving tray 3 enter the packaging bag for packaging. The discharging process of the second-level material receiving tray 3 is generally realized through manual control;

[0039] The first weighing module 4 is used to weigh the storage tank 1; the second weighing module 5 is used to weigh the first-level material receiving tray 2. Both the first weighing module 4 and the second weighing module 5 include a weighing sensor, a data processor, and a display. The weighing sensor can weigh the weight of an object. The data processor can process the data measured by the weighing sensor, including subtracting the two sets of data. The display can display the value measured by the weighing sensor or the value processed by the data processor;

[0040] In this embodiment, with sufficient materials stored in the storage tank 1, the storage tank 1 discharges a preset weight of materials into the first-level material receiving tray 2 each time. The first weighing module 4 can measure the weight of the storage tank 1 before and after discharging, then calculate the difference and display the difference. The second weighing module 5 can measure the weight of the first-level material receiving tray 2 before and after receiving materials, calculate the difference and display the difference. Then, the worker compares the values displayed on the first weighing module 4 and the second weighing module 5. If the two values are the same, the first-level material receiving tray 2 discharges the materials onto the second-level material receiving tray 3, and the second-level material receiving tray 3 discharges the materials into the packaging bag for loading. If the two values are different, the first-level material receiving tray 2 stops discharging, indicating a weighing error.

[0041] In this embodiment, an electronic weighing and manual observation and control method is adopted to weigh and package the materials, with accurate weighing, low manufacturing cost of the weighing device, and low usage cost.

[0042] Embodiment 2

[0043] This embodiment provides a weighing device for traditional Chinese medicine formula granules. The difference from Embodiment 1 is that in this embodiment, the weighing device further includes a data comparator and a control circuit. The discharging processes of the first-level material receiving tray 2 and the second-level material receiving tray 3 are controlled by the control circuit. The differences calculated by the first weighing module 4 and the second weighing module 5 can be compared in the data comparator. If the two differences are the same, the control circuit first controls the first-level material receiving tray 2 to discharge, and then controls the second-level material receiving tray 3 to discharge; if the two differences are different, the control circuit controls the first-level material receiving tray 2 not to discharge. At this time, an alarm or a buzzer can be set on the weighing device to remind the worker of a weighing error.

[0044] In this embodiment, a control circuit is used to manipulate the weighing and packaging of materials. Workers only need to arrange packaging bags at the discharging end of the secondary material receiving tray 3, achieving semi-automatic weighing and packaging, improving the efficiency of material weighing and packaging. However, the weighing device has a relatively high cost, and the usage cost is higher compared to the weighing device in Embodiment 1.

[0045] Embodiment 3

[0046] This embodiment provides a weighing device for traditional Chinese medicine formula granules. Based on Embodiment 1 or Embodiment 2, a method for discharging materials from the primary material receiving tray 2 is also disclosed;

[0047] A material dropping groove 6 is vertically formed in the primary material receiving tray 2, and a swing plate 7 is arranged in the material dropping groove 6. Please refer to Figure 5 When the swing plate 7 is in the horizontal position, it can close the material dropping groove 6. At this time, the upper surface of the swing plate 7 forms an area for receiving the materials discharged from the storage tank 1. Please refer to Figure 6 When the swing plate 7 swings downward, the material dropping groove 6 can be opened. After the swing plate 7 swings downward, its upper surface is in an inclined downward state. At this time, the materials on the upper surface of the swing plate 7 will fall downward along the inclined upper surface of the swing plate 7. The secondary material receiving tray 3 is arranged below the primary material receiving tray 2 and can catch the materials falling from the primary material receiving tray 2.

[0048] In this embodiment, the swing plate 7 can be set as one piece or multiple pieces. Figure 5 And Figure 6 What is shown in

[0049] is the case where two swing plates 7 are provided. The two swing plates 7 are symmetrically arranged on both sides of the material dropping groove 6. The mutually remote ends of the two swing plates 7 are rotationally connected to the side walls of the material dropping groove 6 through rotating shafts. The two swing plates 7 can swing symmetrically in the material dropping groove 6. The upper limit position of the two swing plates 7 when swinging is that the two swing plates 7 are in a horizontal state. After the two swing plates 7 swing downward, the lower ends of the two swing plates 7 approach each other in the middle and have the same bottom height. In this way, during the falling process of the materials, they will be guided by the two swing plates 7 and fall onto the middle part of the secondary material receiving tray 3.

[0050] In this embodiment, please refer to Figure 5 The notch of the material dropping groove 6 is higher than the upper surface of the swing plate 7 when it is in the horizontal position. In this way, the material dropping groove 6 and the swing plate 7 together form a concave-shaped space, which can better receive the materials from the storage tank 1.

[0051] Embodiment 4

[0052] This embodiment provides a weighing device for traditional Chinese medicine formula granules. On the basis of Embodiment 1 or Embodiment 2, a method of discharging materials from the secondary receiving tray 3 is also disclosed;

[0053] Please refer to Figure 3 , a fixed seat 9 is provided below the secondary receiving tray 3. One side of the bottom surface of the secondary receiving tray 3 is rotatably connected to the top of the fixed seat 9. An air cylinder 10 is provided on one side of the fixed seat 9. The piston rod at the output end of the air cylinder 10 is vertically upward. The upper end of the piston rod is in contact with the bottom surface of the secondary receiving tray 3. When the air cylinder 10 drives the piston rod to move vertically, it can drive the secondary receiving tray 3 to swing up and down with the rotation connection point as the fulcrum. Figure 2 What is shown is a schematic diagram of the secondary receiving tray 3 in the state of preparing to receive materials. At this time, the upper surface of the secondary receiving tray 3 is in a horizontal state, and the primary receiving tray 2 has not discharged materials yet; Figure 3 What is shown is a schematic diagram of the secondary receiving tray 3 in the process of receiving materials. At this time, the primary receiving tray 2 is in the state of discharging materials, and the materials fall on the upper surface of the secondary receiving tray 3; Figure 4 What is shown is a schematic diagram of the secondary receiving tray 3 in the state of discharging materials. At this time, the upper surface of the secondary receiving tray 3 is inclined to one side, and the materials on the secondary receiving tray 3 fall downward along the inclined surface. A packaging bag (not shown in the figure) is placed at the inclined lower end of the secondary receiving tray 3.

[0054] Please refer to Figure 5 or Figure 6 , a surrounding plate 11 is provided on the upper surface of the secondary receiving tray 3. The surrounding plate 11 is arranged around the secondary receiving tray 3. The surrounding plate 11 has an opening. The opening is located at the bottom of the secondary receiving tray 3 when the secondary receiving tray 3 is in an inclined state. The packaging bag is placed below the opening. During the discharging process of the secondary receiving tray 3, the materials on the secondary receiving tray 3 will enter the packaging bag through the opening; the caliber of the opening gradually decreases from top to bottom, so that the materials can gradually gather during the falling process, which is beneficial to the packaging of the materials.
