Description

Technical Field

[0001] This utility model belongs to the field of pharmaceutical dispensing technology, specifically relating to an electronic counting and error prevention device based on a double buffer plate. Background Technology

[0002] When filling or dispensing tablets, the tablets need to be counted to ensure the effectiveness of the filling. During filling or dispensing, due to the narrow width of the bottle opening, a funnel is generally used for guidance, and a counter is set between the discharge end and the funnel to count the number of falling drug particles. However, in actual application, the drug particles may hit the inner wall of the funnel during the falling process, causing them to bounce. As a result, some drug particles may pass through the counter twice, which will affect the accuracy of the count. Moreover, for pills or tablets, repeated collisions with the inner wall of the funnel during the falling process can easily cause damage, making it difficult to meet market demands. Summary of the Invention

[0003] The purpose of this invention is to provide an electronic counting error prevention device based on double buffer baffles, which has a reasonable structural design and can prevent rebound.

[0004] The technical solution to achieve the purpose of this utility model is an electronic counting and error prevention device based on a double buffer baffle, including a feeding funnel connected to a dispensing device, a first baffle is provided inside the feeding funnel, the first baffle is located on the diameter of the feeding funnel, and the upper part of the first baffle has a V-shaped clearance groove. The feed end of the feeding funnel is provided with two semi-circular second baffles, and the edges of the two semi-circular second baffles and the connection between them and the feeding funnel are respectively provided with shafts and small spring return torsion springs. The shaft is positioned above both ends of the V-shaped clearance groove of the first baffle. The two semi-circular second baffles block the opening of the feed funnel under the action of the reset torsion spring. When the medicine falls, the gravity of the medicine causes the semi-circular second baffles to rotate downward around the shaft and open. When the semi-circular second baffles are open, they are in the V-shaped relief groove.

[0005] A further preferred embodiment is that the lower part of the first baffle is provided with an inverted V-shaped groove, and the inverted V-shaped groove and the discharge end of the guide funnel form a discharge through hole.

[0006] A further preferred embodiment is that the first baffle is a metal or plastic sheet with a thickness of 0.1-0.5 mm.

[0007] A further preferred embodiment is that the semi-circular second baffle is a metal or plastic sheet with a thickness of 0.1-0.5 mm.

[0008] A further preferred embodiment is that the diameter of the combination of the two semi-circular second baffles matches the inner diameter of the feed funnel.

[0009] A further preferred embodiment is that the feeding funnel is a transparent plastic structural component.

[0010] This invention has several advantages: Its structure is rationally designed. A first baffle is installed inside the feeding funnel to prevent repeated collisions of the medicine within the funnel, thus reducing damage. Two semi-circular second baffles are connected to a shaft via a reset torsion spring. When the medicine falls, these baffles open downwards to facilitate entry. After entry, the torsion springs reset the baffles, preventing them from rebounding upwards to the electronic counter of the dispenser, improving counting accuracy and effectiveness, and effectively preventing counting errors. Furthermore, the overall structure is simple, reducing processing costs. Disassembly and maintenance are convenient, and operation is stable and reliable. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0014] See Figures 1 to 4As shown, an electronic counting and error prevention device based on a double buffer baffle includes a feeding funnel 2 connected to a dispensing device 1. In this embodiment, both the dispensing device and the feeding funnel are conventional structures of the prior art, and are simply applied. There is an electronic counter at the discharge port of the dispensing device, so it is not described in detail. The feeding funnel is a transparent plastic structural component.

[0015] In this embodiment, a first baffle 3 is provided inside the material guiding funnel. The first baffle is located on the diameter of the material guiding funnel, and a V-shaped clearance groove 4 is provided on the upper part of the first baffle. The V-shaped clearance groove is mainly to provide an opening space when the two semi-circular second baffles open downwards, ensuring the effectiveness of opening. The first baffle can divide the space of the material guiding funnel, so that the space for repeated collisions of the medicine is small when it falls in, thus preventing damage caused by repeated collisions. The first baffle is a metal or plastic sheet with a thickness of 0.1-0.5mm.

[0016] Furthermore, the feed end of the feeding funnel is equipped with two semi-circular second baffles 5. A shaft 6 and a low-tension return torsion spring 7 are respectively installed at the connection points between the edges of the two semi-circular second baffles and the feeding funnel. The shaft is positioned above both ends of the V-shaped clearance groove of the first baffle. The return torsion spring has a small tension, allowing it to deform under the weight of the falling agent, thus opening the semi-circular second baffles downwards. The semi-circular second baffles are metal or plastic sheets with a thickness of 0.1-0.5 mm. In practical applications, the combined diameter of the two semi-circular second baffles matches the inner diameter of the feeding funnel.

[0017] In use, the two semi-circular second baffles block the opening of the feed funnel under the action of the reset torsion spring. When the medicine falls, the gravity of the medicine causes the semi-circular second baffles to rotate downward around the shaft and open. When the semi-circular second baffles are open, they are in the V-shaped clearance groove.

[0018] In practical applications, the lower part of the first baffle is provided with an inverted V-shaped groove 8, which forms a discharge through hole with the discharge end of the guide funnel. This ensures that the medicine is smoothly discharged from the discharge port of the guide funnel, avoiding blockage.

[0019] This invention has several advantages: Its structure is rationally designed. A first baffle is installed inside the feeding funnel to prevent repeated collisions of the medicine within the funnel, thus reducing damage. Two semi-circular second baffles are connected to a shaft via a reset torsion spring. When the medicine falls, these baffles open downwards to facilitate entry. After entry, the torsion springs reset the baffles, preventing them from rebounding upwards to the electronic counter of the dispenser, improving counting accuracy and effectiveness, and effectively preventing counting errors. Furthermore, the overall structure is simple, reducing processing costs. Disassembly and maintenance are convenient, and operation is stable and reliable.

[0020] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0021] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
