Description

Technical Field

[0001] This utility model relates to a mixing machine for external pharmaceutical preparations, belonging to the technical field of mixing machines. Background Technology

[0002] Pharmaceutical preparations play a very important role in human health. They can reduce the suffering of patients and prevent them from enduring bitter pain. At the same time, pharmaceutical preparations can also enable them to exert their effects. Pharmaceutical preparations are generally composed of two or more ingredients. In order to ensure that several drugs are fully mixed, a mixing tank is usually used for mixing.

[0003] Chinese Patent Publication No. CN 214106705 U discloses a pharmaceutical preparation mixing device, relating to the technical field of pharmaceutical mixing equipment. The device includes a base, a support plate fixedly mounted on one upper surface of the base, a top plate fixedly mounted on the upper surface of the support plate, racks symmetrically mounted on one outer surface of the top plate, support columns symmetrically mounted on the upper surface of the base, and receiving plates fixedly mounted on the upper surfaces of multiple support columns. A mixing tank is fixedly mounted on the inner wall of the receiving plate, and a support rod is fixedly mounted on the bottom of the inner wall of the mixing tank. This pharmaceutical preparation mixing device, by setting a connecting plate inside the mixing tank, allows the connecting rod on the outer surface of the rotating rod to swing rapidly up and down through the cooperation of a positioning shaft when the rotating shaft drives the connecting plate to rotate at high speed during actual use. Furthermore, the use of weight-adding balls effectively improves the mixing and stirring effect of the device on the drugs, thus enhancing the practicality of the device.

[0004] The above-mentioned device has a relatively unidirectional mixing direction for drugs, and during the stirring process, some drugs may separate into layers due to different densities. This may result in a lower stirring effect and a poorer mixing effect, which in turn affects the drug formation and efficacy.

[0005] Therefore, a mixing machine for external drug preparations is proposed. Utility Model Content

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] Example 1

[0029] like Figure 1-5As shown, this utility model embodiment provides a mixing machine for external drug preparations, including a mixing tank 1. A feed valve 3 is fixedly installed on the top of the mixing tank 1, and a discharge valve 4 is fixedly installed on the bottom of the mixing tank 1. A support frame 5 is fixedly installed on the surface of the mixing tank 1. A mixing mechanism 2 is provided on the surface of the mixing tank 1. The mixing mechanism 2 includes a mounting frame 201, a frame 206, a connecting rod 210, and a hollow tube 212. The mounting frame 201 is fixedly installed on the left side of the top of the mixing tank 1. The frame 206 is located at the top of the mixing tank 1. The hollow tube 212 is located in the inner cavity of the mixing tank 1. The surface of the connecting rod 210 is movably connected to the inner cavity of the hollow tube 212 via a bearing. The connecting rod 210 penetrates the inner cavity of the hollow tube 212 and extends to the bottom of the hollow tube 212. Stirring blades 213 are fixedly installed at the bottom of both the connecting rod 210 and the hollow tube 212. A drive motor 202 is fixedly installed on the top of the mounting frame 201. A lead screw 203 is fixedly connected to the output end of 202. A screw block 204 is threadedly connected to the surface of the lead screw 203. An installation rod 205 is fixedly installed on the right side of the screw block 204. The right side of the installation rod 205 is fixedly installed on the left side of the frame 206. A first bevel gear 209 is movably connected to the top of the inner side of the frame 206. The top of the connecting rod 210 is fixedly connected to the bottom of the first bevel gear 209. A second bevel gear 211 is movably connected to the bottom of the inner side of the frame 206. The top of the hollow tube 212 is fixedly connected to the bottom of the second bevel gear 211. A rotary motor 207 is fixedly installed on the right side of the frame 206. A drive bevel gear 208 is fixedly connected to the output end of the rotary motor 207. The surfaces of the drive bevel gear 208 mesh with the surfaces of the first bevel gear 209 and the second bevel gear 211. The two stirring blades 213 are the same size and face opposite directions.

[0030] By setting up the mixing mechanism 2, the output of the drive motor 202 causes the screw block 204 to drive the frame 206 to move up and down. Through the output of the rotary motor 207, the two stirring blades 213 rotate in opposite directions. By mixing and stirring the drugs at different heights and in different directions, the mixing speed and efficiency between different drugs can be improved, ensuring the uniformity of drug mixing and the effect of drug formation, making it convenient for operators to use.

[0031] Example 2

[0032] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, in one embodiment, scraper plates 214 are fixedly installed on the outer sides of the two stirring blades 213. The outer sides of the scraper plates 214 are attached to the inner wall of the mixing box 1. A slot 215 is opened at the top of the mixing box 1. A hollow tube 212 passes through the inner cavity of the slot 215 and extends into the inner cavity of the mixing box 1. Limiting grooves 216 are opened on both the front and rear sides of the mounting frame 201. The front and rear sides of the screw block 204 are slidably connected to the inner cavities of the two limiting grooves 216. A base plate 6 is fixedly installed at the bottom of the support frame 5. Anchor bolts 7 are threadedly connected to the surface of the base plate 6.

[0033] By setting the scraper 214, the material adhering to the inner wall of the mixing tank 1 can be scraped off, preventing the medicine from sticking to the inner wall of the mixing tank 1, which would prevent the sticky part of the medicine from being discharged and thus waste the medicine. By setting the slot 215, the movement of the hollow tube 212 can be limited, preventing the hollow tube 212 from deviating when moving, which would affect the mixing of medicines at different heights in the inner cavity of the mixing tank 1. By setting the limiting slot 216, the movement of the screw block 204 can be limited, preventing the screw block 204 from rotating synchronously with the lead screw 203, which would affect the adjustment of the height of the stirring blade 213. By setting the anchor bolts 7, the overall equipment can be stabilized, preventing the overall equipment from shaking due to the centrifugal force when the stirring blade 213 rotates, which would affect the mixing effect of the medicine.

[0034] When this utility model is in operation: First, through the output of the rotary motor 207, the active bevel gear 208 engages with the first bevel gear 209 and the second bevel gear 211. The second bevel gear 211 and the first bevel gear 209 rotate in opposite directions. The connecting rod 210 and the hollow tube 212 drive the two stirring blades 213 to mix in opposite directions. Then, through the output of the drive motor 202, the lead screw 203 reciprocates. At this time, the screw block 204 drives the mounting rod 205 and the frame 206 to move up and down synchronously. By moving the frame 206, the stirring blades 213 move up and down synchronously, thereby completing the mixing of the medicine in the inner cavity of the mixing box 1.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
