Abstract
Description
Technical Field
[0001] This utility model relates to the field of traditional Chinese medicine technology, specifically to a drug packaging device. Background Technology
[0002] Currently, some traditional Chinese medicine pharmacies that dispense large quantities of medicines daily have a heavy workload. To simplify the process and improve efficiency, they usually place the kraft paper medicine bags with the opening facing up on a trolley frame or a tray mounted on the trolley. The dispensing staff then push the trolley to the corresponding medicine compartment of the prescription and grab the Chinese medicinal materials. In particular, with the emergence of individually packaged Chinese medicinal materials in recent years, the medicine can be quantified through small packages, eliminating the need for on-site weighing. Dispensing staff can accurately grab the required amount of Chinese medicinal materials based on the quantity of the small packages.
[0003] However, in practice, we found that while kraft paper bags have good strength and can generally keep the opening open to accommodate small medicine packets, it's unavoidable that the bags sometimes don't open wide enough, or the opening collapses due to accidental contact during the dispensing process, requiring the bags to be straightened again. Although each instance doesn't take much time, considering that dispensing traditional Chinese medicine is a highly repetitive and complex process—a single worker might dispense hundreds or even thousands of doses daily—these situations undoubtedly reduce work efficiency significantly and can even lead to errors such as dispensing too much or too little medicine. Utility Model Content
[0004] The purpose of this invention is to provide a drug packaging device that can assist in opening the mouth of a medicine bag and improve the efficiency of dispensing medicine.
[0005] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is: a drug packaging device, comprising a square frame and several sets of bag opening mechanisms evenly distributed in a matrix on the frame; the frame includes two parallel longitudinal bars and several pairs of parallel transverse bars arranged between the longitudinal bars;
[0006] The bag opening mechanism includes two support rods extending along the length of the longitudinal rod. Both ends of the support rods are sleeved on the crossbar via first short tubes, forming a sliding fit with the crossbar. A first limiting nut is provided on the outward-facing side of the two first short tubes at the same end of the two support rods, and a first bag-expanding spring is provided on the inward-facing side. The first limiting nut is threaded into the crossbar, and the first bag-expanding spring is sleeved outside the crossbar. The bag opening mechanism also includes two pairs of second short tubes sleeved on the two support rods. A second bag-expanding spring is sleeved on the support rod on the opposite side of the second short tube, and a second limiting nut is provided on the support rod on the opposite side. The second limiting nut is threaded into the support rod. Vertical bag-expanding rods are provided at the bottom of the four second short tubes of the same set of bag opening mechanisms.
[0007] Preferably, the bag-expanding rod is a rubber rod.
[0008] Preferably, the top of the rubber rod is provided with a bent section, and the bent section is connected to the side wall of the second short tube.
[0009] Preferably, a pair of handles are provided on the outer side wall of the longitudinal bars on both sides of the frame.
[0010] Preferably, the frame is provided with four telescopic support legs at the bottom of the four corners.
[0011] The beneficial effects of this utility model are mainly reflected in its ability to assist in opening the mouth of Chinese medicine bags, facilitating accurate and stable placement of medicines into the bags by dispensing personnel, thus improving work efficiency. Specifically, in use, the frame is first flipped over so that the bag-expanding rods face upwards, forming several rod groups consisting of four-rod units. By adjusting the positions of the first and second limiting nuts, this utility model can also adapt to different sizes of medicine bags used in different Chinese medicine pharmacies. After opening the medicine bag, the cover is placed over the rod group, creating a stable expansion of the bag mouth. After bagging, the frame is flipped over so that the medicine bag is placed flat on the trolley frame, and the utility model is used to keep the bag mouth open, allowing for normal dispensing. After dispensing, as the weight of the medicine bag increases, the frame is lifted upwards to detach the utility model from the medicine bag. This utility model, through its simple design, greatly solves the problems encountered in the process of bulk medicine dispensing, improving overall work efficiency. Attached Figure Description

[0014] Figure 3 This is a schematic diagram of the structure of the bag-expanding rod in a preferred embodiment. Detailed Implementation
[0015] like Figure 1-3 As shown, a drug dispensing device is used in traditional Chinese medicine pharmacies to assist dispensing personnel in their operations, improving work efficiency and reducing work risks. This utility model includes a square frame and several sets of bag opening mechanisms evenly distributed in a matrix on the frame. The frame includes two parallel vertical bars 1 and several pairs of parallel horizontal bars 2 arranged between the vertical bars 1. Figure 1As shown in the illustration, the dimensions of each component of this utility model are relatively large in the illustration, but in actual processing and production, smaller dimensions are preferable, which can reduce the overall weight and manufacturing cost, and lightweight plastic materials are usually used.
[0016] like Figure 2 As shown, the bag opening mechanism includes two support rods 3 extending along the length of the longitudinal rod 1. The two ends of each support rod 3 are sleeved on the transverse rod 2 via first short tubes 4, forming a sliding fit with the transverse rod 2. A first limiting nut 5 is provided on the outward-facing side of the two first short tubes 4 at the same end of the two support rods 3, and a first bag-expanding spring 6 is provided on the inward-facing side. The first limiting nut 5 is used to restrict the position of the first short tubes 4, thereby limiting the distance between the support rods 3. Since this invention is mainly used for expanding the bag opening, it does not require excessive tension; therefore, the first bag-expanding spring 6 is typically a soft spring with relatively low elasticity. The first limiting nut 5 forms a threaded fit with the transverse rod 2. By adjusting the first limiting nut 5, the upper limit of the expandable distance between the two support rods 3 can be changed to prevent excessive expansion. The first bag-expanding spring 6 is sleeved outside the transverse rod 2.
[0017] The bag opening mechanism of this utility model also includes two pairs of second short tubes 7 sleeved on two support rods 3. A second bag-expanding spring 8 is sleeved on the support rod 3 on the opposite side of the second short tube 7, and a second limiting nut 9 is provided on the support rod 3 on the opposite side. The second limiting nut 9 and the support rod 3 form a threaded engagement. Its principle and structure are the same as those of the first short tube, the first limiting nut 5, and the first bag-expanding spring 6 mentioned above, and will not be described again here. Each of the four second short tubes 7 in the same set of bag opening mechanisms is provided with a vertical bag-expanding rod 10 at its bottom. The bag-expanding rod 10 is generally made of rubber, which ensures the effectiveness of bag expansion while being flexible to prevent damage to the bag. Figure 3 As shown, the top of the rubber rod is provided with a bent section, which is connected to the side wall of the second short tube 7. This structure can further improve the flexibility of the bag expanding rod 10, giving it better expansion elasticity and preventing damage to the bag.
[0018] In use, the frame is first flipped over so that the bag-expanding rods 10 face upwards, forming several rod groups consisting of four bag-expanding rods. For ease of operation, a pair of handles 11 can be provided on the outer walls of the longitudinal rods 1 on both sides of the frame for easy gripping. By adjusting the positions of the first limiting nut 5 and the second limiting nut 9, this invention can also adapt to different sizes of medicine bags used in different Chinese medicine pharmacies. After opening the medicine bag, the cover is placed over the rod group to create a stable expansion of the bag opening. After bagging, the frame is flipped over so that the medicine bag is placed flat on the trolley frame, and the medicine bag opening is kept open using this invention, allowing for normal dispensing. Of course, to prevent the frame from pressing down on the bag and causing it to bend, this invention can also be equipped with support legs. Specifically, four telescopic support legs are provided at the bottom of the four corners of the frame, and the length of the telescopic support legs can be adjusted to accommodate bags of different heights. After dispensing the medicine, as the weight of the medicine bag increases, the frame is lifted upwards to detach the invention from the medicine bag. This invention, through its simple design, greatly solves the problems encountered in the process of bulk medicine dispensing and improves overall work efficiency.
