Description

Technical Field

[0001] This utility model relates to the technical field of tablet slicing devices, specifically a device for halving tablet medicines. Background Technology

[0002] Intelligent drug dispensing machines and intelligent drug dispensing machines are widely used in medical institutions to automate the dispensing and distribution of drugs, improve efficiency, and reduce errors. In order to meet the needs of automatic dispensing of more types of tablets, especially when the prescription requires half a tablet, corresponding slicing blades are usually used to cut the whole tablet into slices.

[0003] For example, the tablet splitter and feeder disclosed in CN102159170A can split tablets (T) without moving the cutter (cutting blade) and can dispense the split tablets (T1, T2) separately. The rotor is housed in a container that holds multiple tablets (T). The rotor housing part of the container is cylindrical with a bottom and a tablet discharge port at its bottom. A fixing blade is provided on its outer side. A receiving groove for receiving one tablet is formed at equal intervals around the entire circumference of the rotor, and a circumferential groove is formed for the fixing blade and the support plate to enter.

[0004] The existing technology has the following technical problems: When the existing tablet cutter is used, the blade is a fixed and non-moving part. Although it can achieve the slicing effect of the tablet, it can only be cut by the rotation of the tablet and contact with the blade. As a result, a lot of debris is generated during slicing, which is not conducive to the integrity of the tablet.

[0005] Therefore, we proposed a tablet-cutting device to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a tablet cutting device to solve the problem mentioned in the background art: the existing tablet cutters on the market are fixed parts when in use. Although they can achieve the desired slicing effect, they can only cut by rotating the tablet and contacting the blade. As a result, a lot of debris is generated during slicing, which is not conducive to the integrity of the tablet.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a tablet halving device, comprising a slicing blade and a blade clamp for mounting the slicing blade, a slicing core base is provided below the slicing blade, and a slicing core top cover that allows the tablet to rotate is provided above the blade clamp, the edge of the slicing core top cover has a receiving groove for storing the tablet, and a pressing member is mounted on the bottom of the slicing core top cover through a guide support bearing, the pressing member is used to apply pressure and pushing force to the slicing blade when rotating, the slicing blade is constrained in a sliding groove opened in the blade clamp, and the slicing blade is connected to the blade clamp through an auxiliary spring, the auxiliary spring is used to provide a restoring elastic force when the pressing member does not apply pressure and pushing force to the slicing blade, and the circumferential opening of the slicing core base has a discharge notch for discharging the halved tablet.

[0008] Preferably, the slicing blade is configured as an elastic telescopic structure by means of an auxiliary spring and a blade clamp, and the slicing blade is capable of moving in the radial direction of the blade clamp.

[0009] By adopting the above technical solution, the movement of the slicing blade on the blade clamp enables the slicing blade to move and cut the tablets.

[0010] Preferably, the end of the slicing blade near the bottom extrusion member of the slicing core cover is configured with an arc-shaped structure, and a core cutting blade baffle is installed on the core base below the slicing blade to restrict the movement of the slicing blade.

[0011] By adopting the above technical solution, the slicing blade can be squeezed and pushed by the arc-shaped end of the slicing blade when the extruder rotates.

[0012] Preferably, three extruders are evenly distributed at equal angles at the bottom of the slice core top cover, and the extruders are cylindrical with a circular cross-section.

[0013] By adopting the above technical solution, the extrusion component can be used to intermittently extrude the slicing blade when the top cover of the slicing core rotates.

[0014] Preferably, the sliced ​​core cover is disposed inside a container for storing multiple tablets, and the edge of the sliced ​​core cover has multiple equally spaced receiving slots, the inside of which is used to store a tablet to be cut.

[0015] By adopting the above technical solution, when the top cover of the sliced ​​drug core is rotated, the drugs inside the container can enter the receiving groove on its edge in sequence, thus waiting for the subsequent cutting by the slicing blade.

[0016] Preferably, the tablet to be cut is placed vertically inside the receiving slot.

[0017] By adopting the above technical solution, the medicine is placed vertically, which facilitates subsequent segmentation using a slicing knife.

[0018] Preferably, the slicing blade is used to cut the tablets after it moves. The tablets below the slicing blade fall through the discharge notch first, while the tablets above the slicing blade are blocked and continue to rotate with the top cover of the slicing core until they are separated from the slicing blade and discharged downward through the discharge notch, thus forming a time difference after the tablets are cut and fall.

[0019] By adopting the above technical solution, the time difference of the falling tablets can be used to facilitate subsequent detection of whether the medicine is discharged outward using sensors.

[0020] Preferably, the guide support bearing is located below the top cover of the sliced ​​drug core, and the guide support bearing corresponds one-to-one with the extrusion component.

[0021] By adopting the above technical solution and setting the guide support bearing, rotational support for the extruded parts can be provided.

[0022] Preferably, a gear sleeve is installed at the bottom of the top cover of the sliced ​​drug core, and the rotation of the gear sleeve is controlled by a power component.

[0023] By adopting the above technical solution, the rotation of the power component enables the gear sleeve to drive the top cover of the slice core to rotate synchronously.

[0024] Compared with the prior art, the beneficial effects of this utility model are: the tablet cutting device can slide and cut the tablet with the cutting core cover as the tablet rotates; at the same time, the cutting blade can be pressed and cut by the extruder, which improves the slicing effect of the medicine and reduces the damage rate of the medicine.

[0025] 1. Equipped with a slicing blade, the tablets can be rotated synchronously by the rotation of the slicing core cover. The tablets rotate and come into contact with the slicing blade, thus achieving sliding segmentation. At the same time, when the slicing blade is pressed and moves towards the tablets, it can also cut the tablets, improving the segmentation efficiency.

[0026] 2. It is equipped with a squeezing element. The squeezing element can be rotated synchronously by rotating the top cover of the slicing core. The rotation of the squeezing element can intermittently squeeze the arc-shaped end of the slicing blade, thereby driving the slicing blade to reciprocate.

[0027] 3. A discharge notch is provided. The discharge notch on the tablet core base facilitates the downward drop of the tablets after being sliced ​​by the slicing blade. The tablets above the slicing blade rotate synchronously with the top cover of the tablet core. The rotation of the top cover causes the tablets above the slicing blade to be misaligned with the slicing blade, allowing them to fall downward through the discharge notch. This creates a time difference between the two tablets, which is convenient for subsequent counting or discharge using sensors. Attached Figure Description

[0036] 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.

[0037] Example 1: Please refer to Figures 1-7Existing tablet cutters, where the blade is a fixed, non-moving component, while achieving slicing, produce a significant amount of debris during slicing due to the tablet's rotation and contact with the blade, thus compromising tablet integrity. To address this issue, this embodiment discloses a tablet slicing device comprising a slicing blade 1 and a blade clamp 2 mounted on the slicing blade 1. A slicing core base 3 is located below the slicing blade 1, and a slicing core top cover 4, allowing the tablet to rotate, is located above the blade clamp 2. The top cover 4 has a receiving groove 7 for storing tablets, and a pressing element 5 is mounted at the bottom of the top cover 4 via a guide support bearing 6. The pressing element 5 applies pressure and thrust to the slicing blade 1 during rotation. The slicing blade 1 is constrained by a groove on the blade clamp 2, and is connected to the blade clamp 2 via an auxiliary spring 8. The auxiliary spring 8 provides support when the pressing element 5 is not applying pressure to the slicing blade 1. The slicing core base 3 has a circumferential discharge notch 10 for discharging the halved tablets. The slicing blade 1 is elastically telescopically structured by an auxiliary spring 8 and a blade clamp 2, and the slicing blade 1 can move radially in the blade clamp 2. The end of the slicing blade 1 near the bottom of the slicing core top cover 4 is set with an arc-shaped structure. The slicing core base 3 below the slicing blade 1 is equipped with a core cutting blade baffle 9 to restrict the movement of the slicing blade 1. Three extrusion members 5 are evenly distributed at equal angles at the bottom of the slicing core top cover 4, and the extrusion members 5 are cylindrical members with a circular cross-section. The slicing core top cover 4 is set in a container for storing multiple tablets, and the edge of the slicing core top cover 4 has multiple equally spaced receiving slots 7. The inside of the receiving slot 7 is used to store a tablet to be cut. The guide support bearing 6 is located below the slicing core top cover 4, and the guide support bearing 6 corresponds one-to-one with the extrusion member 5. The tablet to be cut stored in the receiving slot 7 is placed vertically.

[0038] When tablets need to be split, the tablet core top cover 4 is located inside the tablet container. The tablets inside the container can then sequentially enter the receiving groove 7 on the edge of the tablet core top cover 4. When the tablet core top cover 4 rotates, the tablets inside the receiving groove 7 rotate synchronously. After the tablets rotate, they first slide and cut against the blade of the slicing knife 1. Simultaneously, the rotation of the tablet core top cover 4 causes the pressing element 5 below to rotate synchronously. As the pressing element 5 rotates, it gradually contacts the arc-shaped end of the slicing knife 1, thereby pressing the slicing knife 1 and causing it to cut... The slicing blade 1 moves within the groove on the tablet clamping plate 2, and its movement also allows for pressing and cutting of the tablets. This enables the slicing blade 1 to simultaneously slide and press the tablets, improving the tablet segmentation efficiency. The cut tablets are discharged outward through the discharge notch 10 on the slicing core base 3. When the slicing core top cover 4 rotates, the extrusion member 5 at its lower end disengages from the arc-shaped end of the slicing blade 1. Under the action of the auxiliary spring 8, the slicing blade 1 returns to its original position and springs back into the groove on the blade clamping plate 2. This allows for the reciprocating movement of the slicing blade 1, facilitating subsequent continuous segmentation of the tablets.

[0039] Example 2: The technical solution disclosed in this example is a further improvement based on Example 1 described above. The following technical contents are disclosed in this example: Figure 1 , Figure 4 and Figure 7 As shown, after the slicing blade 1 moves, it is used to cut the tablets. After cutting, the tablets below the slicing blade 1 fall through the discharge notch 10 first. The tablets above the slicing blade 1 are blocked and continue to rotate with the top cover 4 of the slicing core until they are separated from the slicing blade 1 and discharged downwards through the discharge notch 10. This creates a time difference after the tablets are cut and fall. A gear sleeve 11 is installed at the bottom of the top cover 4 of the slicing core, and the rotation of the gear sleeve 11 is controlled by a power component.

[0040] The gear sleeve 11 can be rotated by the power component. The rotation of the gear sleeve 11 can make the slice core cover 4 rotate synchronously, thereby providing the rotation power of the slice core cover 4. After the slicer 1 cuts the medicine, the slicer 1 will block the upper part of the medicine. At this time, after the lower part of the medicine falls through the discharge notch 10, the upper part of the medicine will not fall at the same time. Instead, it will continue to rotate with the slice core cover 4 until the medicine and the slicer 1 separate from each other. Only then will the upper part of the medicine fall down through the discharge notch 10. This achieves the time difference of discharge, which is convenient for subsequent monitoring of whether the medicine is discharged by the sensor or counting by the counting sensor.

[0041] In this embodiment, the power component can be controlled by a motor and gear rotation. For example, a large gear is keyed to the gear sleeve 11. When the output shaft of the motor controls the small gear to rotate, the rotation of the small gear can cause the meshing large gear to drive the gear sleeve 11 to rotate, thereby achieving the purpose of power transmission.

[0042] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
