Technical Field
[0001] This utility model relates to the field of traditional Chinese medicine weighing equipment, and in particular to an automatic weighing device for traditional Chinese medicine decoction pieces. Background Technology
[0002] Prepared medicinal herbs are Chinese medicinal materials that have been processed according to traditional Chinese medicine theory and methods, and can be directly used in clinical practice. Prepared medicinal herbs are one of the three pillars of China's traditional Chinese medicine industry. With the development of traditional Chinese medicine, prepared medicinal herbs are being used more and more. In the process of dispensing prepared medicinal herbs, accurate weighing is required to ensure the accuracy and efficacy of the prescription. With the progress of the times, modern weighing equipment such as electronic scales have been gradually applied in the field of weighing traditional Chinese medicine, which has improved the accuracy and efficiency of weighing to a certain extent.
[0003] The above-mentioned and existing technologies have the following drawbacks: After weighing, the existing Chinese medicine weighing equipment cannot effectively and automatically separate the unqualified Chinese medicine pieces from the qualified ones. It mainly relies on the manual handling of Chinese medicine pieces by staff. During the manual handling process, the staff's hands may carry bacteria, dust and other contaminants. Once they come into contact with the Chinese medicine pieces, they are very likely to contaminate the medicine, seriously affecting the quality of the medicine and threatening the patient's medication safety. At the same time, the manual operation process is cumbersome and seriously slows down the weighing efficiency of Chinese medicine pieces. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing Chinese medicine weighing equipment, which relies mainly on manual handling of Chinese medicine slices after weighing, making it impossible to effectively and automatically separate unqualified and qualified Chinese medicine slices after weighing. Furthermore, the manual handling process may result in contamination of the medicine by bacteria, dust, and other pollutants carried by the staff. Therefore, this invention proposes an automatic Chinese medicine slice weighing device.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: an automatic weighing device for traditional Chinese medicine decoction pieces, comprising...
[0006] Base;
[0007] The weighing platform is fixedly connected to the upper surface of the base. An electronic scale is installed inside the weighing platform, and the surface of the weighing platform is equipped with an adjustment mechanism.
[0008] The adjustment mechanism includes a first mounting frame, which is fixedly connected to the surface of the weighing platform. A servo motor is fixedly connected to one side of the first mounting frame, and a lead screw is rotatably connected inside the first mounting frame.
[0009] The lead screw is fixedly connected to the output end of the servo motor. A connecting block is threaded onto the arc surface of the lead screw. A second mounting bracket is fixedly connected to the surface of the weighing platform. A long rod is fixedly connected to the inner wall of the second mounting bracket.
[0010] The long rod has a slider that slides on its arc surface. The slider and the connecting block are fixedly connected to a placement frame on the side that is close to each other. The surface of the weighing platform has two U-shaped holes.
[0011] The aforementioned components achieve the following effect: by setting up an adjustment mechanism, unqualified and qualified Chinese herbal medicine pieces are separated after weighing. This allows staff to classify and collect qualified and unqualified products automatically, reducing the time and effort required for manual operation. Staff no longer need to spend a lot of time manually screening and classifying, improving the efficiency of Chinese herbal medicine preparation and production, and enabling faster fulfillment of patients' medication needs, thus enhancing the practicality of the device.
[0012] Preferably, two collection chambers are fixedly connected to the surface of the base, and two U-shaped guide plates are fixedly connected to the lower surface of the weighing platform.
[0013] The effect achieved by the above components is as follows: by setting up collection bins, qualified or unqualified Chinese herbal medicine pieces will fall into the corresponding collection bins respectively. At the same time, the U-shaped guide plate can guide the Chinese herbal medicine pieces to fall smoothly into the collection bins, ensuring that the Chinese herbal medicine pieces will not fail to enter the collection bins accurately due to scattering or deviation during the transmission process.

One end of the rod is fixedly connected to a round block. The rod is slidably connected to the inner wall of the slot of the arc-shaped block.
[0019] The effects achieved by the above-mentioned components are as follows: by setting up auxiliary devices, it is possible for staff to extract Chinese herbal medicine pieces from the collection chamber in one go, reducing the repetitive actions of staff in taking medicine, avoiding frequent bending over and raising of hands, reducing physical fatigue, and helping staff maintain a good working condition. At the same time, one-time extraction reduces the number of times the medicine pieces are in contact with each other during the extraction process, reducing the possibility of Chinese herbal medicine pieces being contaminated by dust, microorganisms, etc., which is beneficial to the quality and hygiene safety of Chinese herbal medicine pieces.
[0020] Preferably, a spring is fitted onto the arc surface of the insertion rod, and the two ends of the spring are fixedly connected to the circular block and the U-shaped frame, respectively.
[0021] The effect achieved by the above components is that when the insertion rod is aligned with the arc-shaped block slot, the spring force will drive the round block and then drive the insertion rod to automatically insert into the inner wall of the arc-shaped block slot. After insertion, the insertion rod remains stable and does not wobble, which improves the convenience of the device.
[0022] Preferably, a handle is fixedly connected to the surface of the collection box, and the surface of the handle is provided with anti-slip protrusions.
[0023] The above-mentioned components achieve the following effects: the handle provides a point of leverage for workers, especially when the collection box is full of heavy Chinese herbal medicine pieces, the handle makes it easier to move the collection box out; the anti-slip protrusions increase the friction between the hand and the handle, preventing the hand from slipping off the handle during handling.
[0024] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0025] 1. In this utility model, by setting an adjustment mechanism, the unqualified and qualified Chinese herbal medicine pieces are separated after weighing.

[0036] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0037] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0038] like Figures 1-5 As shown, this utility model provides an automatic weighing device for Chinese herbal medicine slices, including a base 1, a weighing platform 2 fixedly connected to the upper surface of the base 1, an electronic scale 5 installed inside the weighing platform 2, and an adjustment mechanism 3 provided on the surface of the weighing platform 2. By setting the adjustment mechanism 3, the device achieves the effect of separating unqualified and qualified Chinese herbal medicine slices after weighing, so that staff can classify and collect qualified and unqualified products automatically, reducing the time and effort costs of manual operation. Staff no longer need to spend a lot of time manually screening and classifying, thus improving the efficiency of Chinese herbal medicine slice weighing. The improved efficiency of the preparation and production process allows for faster fulfillment of patients' medication needs, enhancing the practicality of the device. The surfaces of the two collection chambers 310 are equipped with auxiliary devices 4, enabling staff to easily extract the Chinese herbal medicine slices from the collection chambers 310 in a single operation. This reduces repetitive actions by staff, avoids frequent bending and lifting, lowers fatigue, and helps staff maintain a good working condition. Furthermore, the single extraction reduces the number of times the medicine slices are handled during extraction, decreasing the likelihood of contamination by dust, microorganisms, etc., thus contributing to the quality and hygiene safety of the Chinese herbal medicine slices.
[0039] The specific settings and functions of its adjustment mechanism 3 and auxiliary device 4 will be discussed below.
[0040] like Figure 2 and Figure 3As shown, the adjustment mechanism 3 includes a first mounting bracket 301, which is fixedly connected to the surface of the weighing platform 2. A servo motor 304 is fixedly connected to one side of the first mounting bracket 301. A lead screw 302 is rotatably connected inside the first mounting bracket 301. The lead screw 302 is fixedly connected to the output end of the servo motor 304. A connecting block 303 is threaded onto the arc surface of the lead screw 302. A second mounting bracket 305 is fixedly connected to the surface of the weighing platform 2. A long rod 306 is fixedly connected to the inner wall of the second mounting bracket 305. A sliding contact is slidably connected to the arc surface of the long rod 306. Block 307, slider 307 and connecting block 303 are fixedly connected to a placement frame 308 on their adjacent sides. Two U-shaped holes 309 are opened on the surface of the weighing platform 2. Two collection bins 310 are fixedly connected to the surface of the base 1. Two U-shaped guide plates 311 are fixedly connected to the lower surface of the weighing platform 2. By setting the collection bins 310, qualified or unqualified Chinese herbal medicine pieces will fall into the corresponding collection bins 310 respectively. At the same time, the U-shaped guide plates 311 can guide the Chinese herbal medicine pieces to fall smoothly into the collection bins 310, ensuring that the Chinese herbal medicine pieces will not scatter during the transmission process. If the medicine falls or deviates and cannot accurately enter the collection bin 310, a cleaning pad 312 is slidably connected to the lower surface of the placement frame 308. The cleaning pad 312 is made of sponge material. The sponge cleaning pad 312 can continuously wipe and clean the surface of the electronic scale 5 as the placement frame 308 moves. During the weighing process of Chinese herbal medicine pieces, fine powder or debris may fall onto the surface of the electronic scale 5. The continuous wiping of the cleaning pad 312 can effectively remove residues and ensure the accuracy of the weighing results of Chinese herbal medicine pieces. At the same time, the continuous wiping of the cleaning pad 312 can prevent impurities from entering the scale. Inside the sub-scale 5, to reduce the probability of equipment malfunction, the cleaning pad 312 is fixedly connected to both sides by a bracket 313, and the placement frame 308 is fixedly connected to both sides by a fixing plate 314. Two rotating plates 315 are rotatably connected to the surface of the fixing plate 314. A round rod 316 is fixedly connected to the side of the two rotating plates 315 that is close to each other. The size of the round rod 316 matches the size of the bracket 313, achieving the effect of periodically replacing the cleaning pad 312. As usage time increases, the cleaning pad 312 absorbs a large amount of Chinese medicine debris, powder, and stains, reducing its cleaning ability. Regular replacement ensures that the cleaning pad 312 is always in a good clean condition, continuously and effectively cleaning the surface of the electronic scale 5.
[0041] like Figure 4 and Figure 5As shown, the auxiliary device 4 includes two sliding holes 41, which are respectively opened on the surfaces of two collection chambers 310. A collection box 42 is slidably connected to the inner wall of the sliding hole 41. A U-shaped frame 43 is fixedly connected to the surface of the collection chamber 310. An arc-shaped block 44 is fixedly connected to the surface of the collection box 42. The arc-shaped block 44 is slidably connected to the inner wall of the U-shaped frame 43. A slot is opened on the surface of the arc-shaped block 44. A rod 45 is slidably inserted into the U-shaped frame 43. A round block 46 is fixedly connected to one end of the rod 45. The rod 45 is slidably connected to the inner wall of the slot of the arc-shaped block 44. A spring 47 is sleeved on the arc surface of the rod 45. The two ends of the spring 47 are fixedly connected to the round block 46 and the U-shaped frame 43, respectively. The device is fixedly connected. When the insertion rod 45 is aligned with the slot of the arc-shaped block 44, the elastic force of its spring 47 will drive the round block 46, which in turn will drive the insertion rod 45 to automatically insert into the inner wall of the slot of the arc-shaped block 44. After insertion, the insertion rod 45 remains stable and does not wobble, which improves the convenience of the device. The surface of the collection box 42 is fixedly connected to the handle 48. The surface of the handle 48 is provided with anti-slip protrusions. The existence of the handle 48 provides a point of leverage for the staff. Especially when the collection box 42 is full of heavy Chinese herbal medicine pieces, it is easier to move the collection box 42 out through the handle 48. The anti-slip protrusions increase the friction between the hand and the handle 48, preventing the hand from slipping off the handle 48 during the handling process.
[0042] The overall working principle is as follows: First, the Chinese herbal medicine slices are placed on the surface of the electronic scale 5, and the slices must be within the placement frame 308. Then, the electronic scale 5 is used to weigh them. When the weighing result is inconsistent with the standard, the servo motor 304 is activated to drive the lead screw 302 to rotate. Then, the connecting block 303 moves to the left along the arc surface of the lead screw 302. The connecting block 303 drives the placement frame 308 to move. The placement frame 308 drives the cleaning pad 312 below to wipe and clean the surface of the electronic scale 5. The placement frame 308 drives the slider 307 to slide to the left along the arc surface of the long rod 306. At this time, the placement frame 308 will drive the Chinese herbal medicine slices to the left until the unqualified Chinese herbal medicine slices fall down from the through hole 309 along the U-shaped guide plate 311 into the collection bin 310 on the left. When the weighing result of the Chinese herbal medicine slices is qualified, the servo motor 304 is activated to drive the lead screw 302 to rotate. Then, the connecting block 303 moves to the right along the arc surface of the lead screw 302. The connecting block 303 drives the placement frame 308 to move, and the placement frame 308 drives the cleaning pad 312 below to wipe and clean the surface of the electronic scale 5. The placement frame 308 drives the slider 307 to slide to the right on the arc surface of the long rod 306. At this time, the placement frame 308 will drive the Chinese herbal medicine pieces to move to the right until the qualified Chinese herbal medicine pieces fall down from the U-shaped hole 309 along the U-shaped guide plate 311 into the collection bin 310 on the right. By setting the adjustment mechanism 3, the unqualified Chinese herbal medicine pieces and qualified Chinese herbal medicine pieces are separated after the Chinese herbal medicine pieces are weighed. This allows the staff to classify and collect qualified and unqualified products, automatically complete the separation of qualified and unqualified pieces, reduce the time and effort cost of manual operation, and eliminate the need for staff to spend a lot of time on manual screening and classification. This improves the efficiency of Chinese herbal medicine preparation and production, can meet the medication needs of patients more quickly, and improves the practicality of the device.
[0043] When it is necessary to extract the Chinese herbal medicine pieces from the collection chamber 310 at once, pull the round block 46 to move the insertion rod 45 upward along the inner wall of the slot of the arc-shaped block 44 until the insertion rod 45 moves away from the inner wall of the slot of the arc-shaped block 44. Then pull the handle 48 to move the collection box 42 backward along the inner wall of the sliding hole 41. The collection box 42 moves the Chinese herbal medicine pieces inside the collection box 42 backward, and the collection box 42 moves the arc-shaped block 44 backward until the collection box 42 moves away from the inner wall of the sliding hole 41. When it is necessary to return the collection box 42 to its original position, push the collection box 42 to move along the inner wall of the sliding hole 41. The collection box 42 moves the arc-shaped block 44 to move along the inner wall of the U-shaped frame 43. When the slot of the arc-shaped block 44 is aligned with the insertion rod 45, the elastic force of its spring 47 will drive the round block 46 and then drive the insertion rod 45 to automatically insert into the inner wall of the slot of the arc-shaped block 44. By setting the auxiliary device 4, it is possible to facilitate the one-time extraction of Chinese herbal medicine pieces in the collection chamber 310 by the staff, reducing the repetitive medicine-retrieving actions of the staff, avoiding the staff to frequently bend over, raise their hands, etc., reducing physical fatigue, and helping the staff to maintain a good working condition. At the same time, the one-time extraction reduces the number of times the medicine pieces are in contact with the medicine pieces during the medicine-retrieving process, reducing the possibility of the Chinese herbal medicine pieces being contaminated by dust, microorganisms, etc., which is beneficial to the quality and hygiene safety of the Chinese herbal medicine pieces.
[0044] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
