Description

Technical Field

[0001] The utility model relates to the technical field of tablet grinding, in particular to a tablet grinding device. Background Art

[0002] Tablet milling is the process of converting solid tablets or drug particles into powder for easier swallowing or other uses. This method is often used in specific situations, such as when administering medication to infants or the elderly, or when the medication needs to be mixed with food for easier administration.

[0003] For example, a Chinese utility model patent (CN219441894U) discloses a tablet grinding device, which records: "The tablet grinding device adopts a circular rotating grinding method to grind the tablets, and can screen the powder while grinding, so that the tablets are ground more finely and evenly. At the same time, there is a large gap between the grinding roller and the grinding box, and the internal space of the grinding box is sufficient, which is convenient for cleaning and maintenance of the grinding device after grinding and easy to use." It also records the technical problem that "after the grinding device is used, it is difficult to clean the powder in the grinding device, and the cleaning is time-consuming and labor-intensive. The powder after grinding is not fine and uniform enough."

[0004] To sum up the above, it can be known that in the prior art, a paddle is used to grind the medicine in combination with a screen to collect the qualified powder. However, this method has the following technical problems: in actual use, part of the powder will move to both sides of the paddle under the push of the paddle, which makes it difficult to collect more powder. As a result, more powder will remain in the annular grinding groove, causing waste of medicine and increasing the difficulty of cleaning later. For this reason, the present application proposes a tablet grinding device to solve the technical problems mentioned in the above patents and provide a new technical solution. Utility Model Content

[0028] As described in the background art, in actual use of this method, part of the medicine powder will move to both sides of the paddle plate under the push of the paddle plate, making it difficult to collect more medicine powder, resulting in more medicine powder remaining in the annular grinding groove, causing drug waste and increasing the difficulty of subsequent cleaning.

[0029] In order to solve this technical problem, the utility model provides a tablet grinding device, which is used to reduce the amount of drug powder remaining inside the device after the drug is ground.

[0030] Specifically, please refer to Figure 1-Figure 2 The tablet grinding device specifically includes:

[0031] The device comprises a housing 1, a grinding mechanism 2 is arranged outside the housing 1, and a cleaning mechanism 3 is arranged outside the housing 1;

[0032] The grinding mechanism 2 includes a first motor 4 fixedly connected to the outside of the device housing 1. The output end of the first motor 4 passes through the top and bottom surfaces of the device housing 1 and is fixedly connected to a cross rod 5. The bottom of the device housing 1 is threadedly connected to a grinding shell 9.

[0033] The tablet grinding device provided by the utility model places tablets in the interior of the grinding shell 9, and after the grinding shell 9 is connected to the device housing 1 by threads, the grinding block 7 tightly presses the tablets under the action of the gravity of the grinding block 7 and the weight block 8, and then the first motor 4 is started, and the grinding block 7 can be driven to rotate through the cross rod 5 and the sliding sleeve 6 to grind the medicine. The medicine ground into powder will be directly present in the interior of the grinding shell 9, and the medicine partly adhered to the bottom of the grinding block 7 can be shaken to the interior of the grinding shell 9 by shaking the device housing 1 after the grinding shell 9 is separated from the device housing 1, so that the vibration generated by the grinding block 7 hitting the inner wall of the grinding shell 9 will vibrate the part of the medicine into the interior of the grinding shell 9. The operation is simple and convenient, and it is avoided that there is a lot of medicine powder remaining in the interior of the device after the medicine is ground, which leads to the waste of medicine, and at the same time, it reduces the subsequent cleaning pressure on the device, and improves the practicality of the device.

[0034] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0035] Embodiment 1:

[0036] Please refer to Figure 2-Figure 5 , a tablet grinding device, comprising:

[0037] The outside of the cross rod 5 is slidably connected to a sliding sleeve 6, and the end of the sliding sleeve 6 away from the device housing 1 is fixedly connected to a grinding block 7, and the side of the grinding block 7 close to the sliding sleeve 6 is fixedly connected to a weight block 8. The gravity of the grinding block 7 and the weight block 8 directly squeezes and crushes the medicine, thereby improving the grinding effect of the medicine.

[0038] A limiting spring 10 is fixedly connected inside the cross rod 5, and a protective plate 11 is fixedly connected to one end of the limiting spring 10 close to the sliding sleeve 6. The protective plate 11 is slidably connected to the inner wall of the cross rod 5, and a fixing plate 13 is fixedly connected to the inner wall of the cross rod 5. The fixing plate 13 limits the movement trajectory of the block 12, thereby making the sliding of the block 12 more stable.

[0039] A block 12 is fixedly connected to the side of the protection plate 11 away from the limiting spring 10. The block 12 is slidably connected to the inner wall of the fixed plate 13. A slot 14 is provided inside the sliding sleeve 6. The block 12 is adapted to the slot 14. The inclined surface of the slot 14 can squeeze the block 12 back into the inside of the cross rod 5 when the overall length of the cross rod 5 and the sliding sleeve 6 changes from the longest to the shortest, thereby avoiding manual operation by the operator and improving the convenience of using the device.

[0040] Through the above structural design, by placing the tablets inside the grinding shell 9, after the grinding shell 9 and the device housing 1 are connected by threads, the grinding block 7 is tightly pressed by the gravity of the grinding block 7 and the weight block 8. In this process, by adding the number of tablets, the overall length of the cross rod 5 and the sliding sleeve 6 is changed accordingly, and the inclined surface between the block 12 and the slot 14 pushes the block 12 back to the inside of the cross rod 5, so that the limiting spring 10 is compressed by force. After the assembly is completed, the first motor 4 can be started, and the grinding block 7 can be driven to rotate through the cross rod 5 and the sliding sleeve 6 to grind the medicine. The medicine ground into powder will be directly present in the grinding shell 9. After the sheet is ground to a certain extent, when the cross rod 5 and the sliding sleeve 6 move relative to each other, after the position of the block 12 corresponds to the position of the slot 14, the block 12 will move toward the inside of the slot 14 under the action of the limiting spring 10, thereby limiting the position of the cross rod 5 and the sliding sleeve 6, thereby avoiding the separation of the cross rod 5 and the sliding sleeve 6. After grinding, force is applied to the device housing 1 and the grinding shell 9, so that the device housing 1 and the grinding shell 9 move relative to each other, and then the grinding shell 9 is removed. After the grinding shell 9 is separated from the device housing 1, the vibration generated by the impact of the grinding block 7 on the inner wall of the grinding shell 9 will vibrate some of the drugs stuck to the bottom of the grinding block 7 into the inside of the grinding shell 9.

[0041] Embodiment 2:

[0042] The tablet grinding device provided in Example 1 is further optimized. Specifically, Figure 3-Figure 4 As shown, the cleaning mechanism 3 includes a second motor 15 fixedly connected to the outside of the device housing 1, and the output end of the second motor 15 passes through the upper and lower surfaces of the top of the device housing 1 and is fixedly connected with fan blades 16. The fan blades 16 first remove the powder and then dry the residual water inside the device, thereby improving the cleaning effect and efficiency of the device on the powder.

[0043] A first cleaning tube 17 is fixedly connected to the inside of the device housing 1, and a first limiting valve 19 is movably connected to the inside of the first cleaning tube 17. A second cleaning tube 18 is fixedly connected to the inner wall of the grinding shell 9, and a second limiting valve 20 is movably connected to the inside of the second cleaning tube 18. The first limiting valve 19 and the second limiting valve 20 effectively prevent leakage of the drug, thereby improving the stability of the device.

[0044] Through the above-mentioned structural design, by opening the first limiting valve 19 and the second limiting valve 20 and starting the second motor 15, the fan blades 16 can be driven to rotate, thereby driving the air flow, so that the air enters the inside of the device housing 1 and the grinding shell 9 from the first cleaning pipe 17, and then flows out from the second cleaning pipe 18, thereby reducing the residual powder inside the device housing 1 and the grinding shell 9, and then the second motor 15 is turned off, and water is added from the inside of the first cleaning pipe 17. The water flow flushes the inside of the device housing 1 and the grinding shell 9, and the water after flushing carries the medicine and flows out from the inside of the second cleaning pipe 18, and then the second motor 15 is started to drive the fan blades 16 to rotate, thereby driving the air flow, and the inside of the device housing 1 is air-dried.
