Abstract
Description
Technical Field
[0001] This utility model relates to the field of drug weighing technology, and in particular to a drug weighing device. Background Technology
[0002] In the process of drug preparation, dosage directly affects efficacy, so weighing devices are often needed to ensure accurate therapeutic effects. However, drugs come in various forms, including tablets, powders, and granules, which often require the use of containers or weighing paper for weighing. Powdered drugs tend to adhere to the inner walls of containers, affecting weighing accuracy; while if weighing paper is used, it is difficult for operators wearing dust gloves to handle single sheets—multiple sheets sticking together further interferes with weighing accuracy.
[0003] Existing patent CN220398693U describes a medicine weighing box, including a weighing box and a lid. The lid is movably mounted on the top outer side of the weighing box. An electronic scale and a display screen are located on the top right end of the weighing box.

Support plates are symmetrically arranged on the top left end of the fixed plate, and a rotating shaft is rotatably mounted between the support plates. A roll of lint-free paper is fixedly mounted in the middle of the rotating shaft. This medicine weighing box is easy to use and can accurately weigh different types of tablet, granular, and powdered medicines. Furthermore, the use of a roll of lint-free paper not only makes it easy for staff to handle and use the lint-free paper but also avoids the impact of multiple sheets of lint-free paper adhering together on the accuracy of the medicine weighing. In addition, the disposable lint-free paper can prevent powdered medicines from being affected by powder residue adhering to them, thus ensuring the accuracy of subsequent medicine weighings.
[0004] However, when using the above method to weigh medicines with cleanroom paper, the powdered medicine needs to be poured onto the cleanroom paper first.

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0018] The embodiment of this application is as follows:
[0019] Please see Figure 1-3 , Figure 1 This is a schematic diagram of the overall structure of a medicine weighing device according to this utility model. Figure 2 This is a schematic diagram of the paper-taking device of this utility model. Figure 3 This is a schematic diagram of the structure of the sleeve shaft of this utility model.
[0020] This utility model provides a medicine weighing device, including a weighing base 101, an electronic scale 102, and a paper picking device, as well as a feeding device. The feeding device includes a feeding hopper 103, a mounting ring 104, a connecting rod 105, a support column 106, and a rotating assembly. The rotating assembly includes a rotating sleeve 107 and a limiting ring 108. The paper picking device includes a paper box 109, a paper roll 110, a sleeve shaft 111, and a cutting assembly. The cutting assembly includes a cutter 113, a pressure plate 114, and a connecting spring 115. The cutting assembly also includes a comparison ruler 117. The aforementioned solution solves the problem that when using cleanroom paper to weigh medicines, the powdered medicine needs to be poured onto the cleanroom paper first, but when pouring the powdered medicine, the powdered medicine is easily spilled out of the cleanroom paper area due to hand shaking.
[0021] In this embodiment, the connecting rod 105 is turned by the cooperation of the rotating component, so that the connecting rod 105 drives the mounting ring 104 and the dispensing hopper 103 to rotate above the electronic scale, thereby pouring the powdered medicine onto the dust-free paper through the dispensing hopper 103, avoiding the powdered medicine from spilling out of the dust-free paper area.
[0022] The support column 106 is fixedly installed on the weighing base 101. The connecting rod 105 is rotatably installed on the support column 106 via the rotating assembly. The mounting ring 104 is fixedly installed on the connecting rod 105 and located at the end of the connecting rod 105 away from the support column 106. The feeding hopper 103 is fixedly installed inside the mounting ring 104. The support column 106 is fixed to the weighing base 101 by screws. The connecting rod 105 is perpendicular to the support column 106. The mounting ring 104 is welded to the outside of the feeding hopper 103. After the dust-free paper is taken out by the paper taking device, the dust-free paper is laid on the electronic scale. By cooperating with the rotating assembly, the connecting rod 105 is moved, causing the connecting rod 105 to drive the mounting ring 104 and the feeding hopper 103 to rotate above the electronic scale. Powdered medicine is then fed into the feeding hopper 103, ensuring that the powdered medicine falls accurately onto the dust-free paper and preventing the powdered medicine from spilling out of the dust-free paper area.
[0023] Secondly, the limiting ring 108 is fixedly installed on the support column 106; the rotating sleeve 107 is rotatably installed on the support column 106 and contacts the limiting ring 108. The limiting ring 108 is welded to the support column 106. The axis of the rotating sleeve 107 coincides with the axis of the support column 106. The limiting ring 108 facilitates the support of the rotating sleeve 107. The rotational cooperation between the rotating sleeve 107 and the support column 106 facilitates the deflection of the connecting rod 105.
[0024] Furthermore, the paper dispensing box 109 is fixedly installed on the weighing base 101. The paper dispensing box 109 is provided with a magnetic cover 118, which forms a magnetic attraction structure with the paper dispensing box 109. The paper dispensing box 109 is also provided with a paper dispensing slot 112. The sleeve shaft 111 is rotatably installed inside the paper dispensing box 109. The paper roll 110 is fitted onto the sleeve shaft 111. The cutting assembly is installed on the paper dispensing box 109. The paper dispensing box 109 has a square structure, and the sleeve shaft 111 is a stepped shaft. The sleeve shaft 111 is rotatably engaged with the paper dispensing box 109 through a bearing. The sleeve shaft 111 facilitates the fitting of the paper roll 110. By rotating the sleeve shaft 111, the dust-free paper on the paper roll 110 is pulled out from the paper dispensing slot 112, and the dust-free paper is cut by the cutting assembly, thereby realizing the retrieval of the dust-free paper.
[0025] Furthermore, the cutter 113 is slidably mounted on the paper dispenser 109 and extends into the paper dispenser slot 112. The paper dispenser slot 112 is also provided with a cutting groove 116 on the side near the cutter 113. The pressure plate 114 is fixedly mounted on the cutter 113. The two ends of the connecting spring 115 are fixedly connected to the pressure plate 114 and the paper dispenser 109, respectively. The pressure plate 114 is welded to the top of the cutter 113. The connecting spring 115 is provided on both sides of the bottom of the pressure plate 114. Through the elastic force of the connecting spring 115, the pressure plate 114 can be reset after being pressed down. By pressing the pressure plate 114, the pressure plate 114 presses the cutter 113, causing the cutter 113 to enter the cutting groove 116 and cut the dust-free paper.
[0026] Finally, the comparison ruler 117 is fixedly installed on the paper dispenser 109 and close to the paper slot 112. The comparison ruler 117 is fixed to the outside of the paper dispenser 109 by adhesive. With the setting of the comparison ruler 117, the size of the dust-free paper pulled out is appropriate.
[0027] In this embodiment, during use, the magnetic cover 118 is opened, the paper roll 110 is placed on the sleeve shaft 111, and then the dust-free paper is pulled out to the outside of the paper tray 112. The magnetic cover 118 is closed, and after comparing the length with the display of the comparison ruler 117, the dust-free paper is pulled out to a suitable position. Then, the pressure plate 114 is pressed down, so that the connecting spring 115 is compressed. The pressure plate 114 presses the cutter 113 down, so that the cutter 113 moves down and cuts the dust-free paper. The cut dust-free paper is laid on the electronic scale. Then, through the rotational cooperation of the rotating sleeve 107 and the support column 106, the connecting rod 105 drives the feeding hopper 103 to rotate above the electronic scale, and the powdered medicine is poured into the feeding hopper 103, so that the powdered medicine is accurately poured onto the dust-free paper. At this time, the dust-free paper can be weighed by the electronic scale, avoiding the powdered medicine from spilling out of the dust-free paper area.
