Description

Technical Field

[0001] The utility model relates to the technical field of drug stirring, in particular to a drug mixing and stirring mechanism capable of automatic feeding. Background Art

[0002] The drug mixing and stirring mechanism is a device widely used in industries such as pharmaceuticals, chemicals, and feeds. It mainly consists of a stirring container, a stirrer, a driving device, etc. The stirring container provides a mixing space for drugs and additives, usually made of corrosion-resistant and easy-to-clean materials. The stirrer is the core component, with various forms such as paddle type and spiral type, which fully mixes drugs and additives through rotation or reciprocating motion. The driving device provides power for the stirrer, and motors, pneumatic motors, etc. can be used. The drug mixing and stirring mechanism can accurately control the stirring speed and time, ensure the accurate ratio of drugs and additives, and improve the quality and efficiency of mixing. At the same time, it also has the characteristics of simple operation, safety and reliability, providing an important guarantee for the production process of various industries.

[0003] However, in the feeding process of some existing drug mixing and stirring mechanisms, drugs are usually directly poured into the stirring tank. On the one hand, excessive feeding at one time is very likely to cause blockage during feeding. Due to the lack of a reasonable control mechanism, a large amount of drugs pour into the feeding port at the same time and are likely to get stuck in the narrow channel, hindering the smooth feeding of subsequent drugs. This will not only affect the production progress but also require a lot of time and manpower to clean the blockage. On the other hand, excessive feeding will also result in the situation where two or more drugs cannot be fully mixed. When a large amount of drugs enter the stirring tank instantaneously, they just pile up together and cannot achieve uniform distribution and sufficient contact. This will greatly reduce the mixing effect of drugs and affect the quality of the final product. Therefore, in view of the above deficiencies, a drug mixing and stirring mechanism capable of automatic feeding is proposed to solve the above problems. Summary of the Utility Model

The motor 4 is installed inside the housing 3 and provides power through the driving shaft 5 at the output end. A cam 6 is fixedly connected to the outside of the driving component. Two sliding plates 7 are slidably connected to the top of the mixing tank 2. The outside of the cam 6 is in contact with one side of the sliding plate 7 close to the driving shaft 5. The cam 6 rotates as the driving shaft 5 rotates. The shape of the cam 6 is oval, and its function is to intermittently squeeze the sliding plate 7 to cause the sliding plate 7 to displace, thereby realizing automatic feeding of drugs. A sliding plate 8 is fixedly connected to the far side of each of the two sliding plates 7. The bottom of the sliding plate 8 is slidably connected to the top of the mixing tank 2. A dropping groove 12 is formed inside the sliding plate 8. When the dropping groove 12 is aligned with the opening at the bottom of the hopper 13, the drugs inside the hopper 13 will fall into the feeding pipe 14.

[0034] Refer to Figures 2 to 4 , two sliding rods 9 are fixedly connected to the far side of each of the two sliding plates 7. Springs 10 are sleeved on the outside of multiple sliding rods 9. One end of each spring 10 is fixedly connected to the outside of the sliding plate 7, and the other end is fixedly connected to the outside of the hopper 13. When the cam 6 squeezes the sliding plate 7, the spring 10 is compressed to store energy; when the cam 6 leaves the sliding plate 7, the spring 10 releases energy to reset the sliding plate 7 and the sliding rod 9. An extrusion ball 11 is fixedly connected to the far side of each of the multiple sliding rods 9. The function of the sliding rod 9 is to drive the extrusion ball 11 to squeeze the drugs inside the hopper 13 under the extrusion of the cam 6. Dropping grooves 12 are formed inside each of the two sliding plates 8. Hoppers 13 are slidably connected to the top of the two sliding plates 8. The near sides of the two hoppers 13 are respectively fixedly connected to the left and right sides of the housing 3. The outer side wall of the sliding rod 9 is slidably connected inside the hopper 13. An opening is formed at the bottom of the hopper 13. Feeding pipes 14 are fixedly connected to the left and right sides of the mixing tank 2. The function of the extrusion ball 11 is to squeeze the drugs inside the hopper 13 so that the drugs can smoothly fall into the feeding pipe 14. One end of the feeding pipe 14 corresponds to the opening at the bottom of the hopper 13, and the other end extends into the mixing tank 2. A stirring component for receiving drugs is arranged outside the driving component.

[0035] Refer toFigures 2 to 4 , the stirring assembly includes a plurality of connecting rods 15. The inner parts of the plurality of connecting rods 15 are fixedly connected to the outside of the drive shaft 5, and a material receiving ring 16 is fixedly connected to the outside of the plurality of connecting rods 15.

The function of the scraping plate 19 is to stir the material on the top of the material blocking plate 21 to prevent the medicine from accumulating at the bottom. The bottom of the scraping plate 19 is slidably connected to the top of the material blocking plate 21. A plurality of discharge grooves 22 are formed in the inside of the material blocking plate 21. The function of the material blocking plate 21 is to block the medicine to prevent the medicine from directly entering the discharge pipe 23, and at the same time provide a stirring platform for the scraping plate 19. A discharge pipe 23 is fixedly connected to the bottom of the conical ring 20, and a valve 24 is arranged on the outside of the discharge pipe 23. The function of the valve 24 is to control the on-off of the discharge pipe 23. When the stirring is completed, the valve 24 is opened, and the medicine can be collected through the discharge pipe 23; when it is necessary to pause or stop during the stirring process, the valve 24 is closed to prevent the outflow of the medicine.

[0036] Refer to Figures 3 to 5, on both the front and back sides of the top of the mixing tank 2, there are fixed water inlet pipes 25. The function of the water inlet pipes 25 is to introduce external water into the interior of the mixing tank 2 to provide water source for the cleaning process. A water pipe is connected to the outside of the water inlet pipes 25. On the adjacent sides of the two water inlet pipes 25, there are fixed output pipes 26. On the outside of the two output pipes 26, there are fixed limit rings 27. On the outside of the two limit rings 27, there are rotatably connected rotating sleeves 28. The function of the limit ring 27 is to limit the position of the rotating sleeve 28 to prevent the rotating sleeve 28 from shifting or falling off during rotation. The outside of the output pipe 26 is rotatably connected to the inside of the rotating sleeve 28. Inside the two rotating sleeves 28, there are fixed fixing frames 29. On the outside of the two fixing frames 29, there are fixed multiple fan blades 30. The function of the fixing frame 29 is to fix the fan blades 30 and connect the fan blades 30 to the rotating sleeve 28. The function of the fan blades 30 is to rotate under the impact of water flow, thereby driving the rotating sleeve 28 and the spray heads 31 to rotate together. At the bottom of the two rotating sleeves 28, there are fixed multiple spray heads 31. The function of the output pipe 26 is to transport the water in the water inlet pipe 25 into the inside of the rotating sleeve 28 to provide water source for the spray heads 31. The main function of the spray heads 31 is to spray water onto various parts inside the mixing tank 2 to achieve comprehensive cleaning. At the four corners of the bottom of the bottom plate 1, there are fixed columns 32. The main function of the columns 32 is to support the entire device to ensure that there is no shaking or tilting during the mixing process.

[0037] Working principle: When it is necessary to use this drug mixing and stirring mechanism, different drugs can be added into the two hoppers 13 respectively. Subsequently, the motor 4 can be started to drive the drive shaft 5 and the cam 6 to rotate through the motor 4. As the cam 6 rotates, it will intermittently squeeze the sliding plate 7 to displace, and then the sliding rod 9 can slide inside the hopper 13 and compress the spring 10. At this time, the extrusion ball 11 will extrude the drugs inside the hopper 13. At the same time, as the sliding plate 7 displaces, it will drive the sliding plate 8 to displace, and then the dropping slot 12 can be intermittently aligned with the slot at the bottom of the hopper 13. At this time, the drugs inside the hopper 13 will fall into the inside of the feed pipe 14 and then enter the inside of the mixing tank 2. At the same time, by means of the rotation of the drive shaft 5, the material receiving ring 16 and the connecting rod 15 can make a circular motion, so as to receive the drug material and carry out preliminary mixing, and finally it will fall into the inside of the conical ring 20. At this time, the large stirring blades 17 and the small stirring blades 18 can be used to stir and mix the drugs inside, and at the same time, the rotation of the scraping plate 19 can be used to stir the materials on the top of the baffle plate 21 to prevent accumulation at the bottom;

[0038] After the stirring is completed, the valve 24 can be opened to collect the stirred medicine through the discharge pipe 23. When the inside needs to be cleaned after the medicine stirring is completed, a water pipe can be connected to the outside of the water inlet pipe 25. At this time, water will enter the inside of the output pipe 26 through the water inlet pipe 25 and then enter the inside of the rotating sleeve 28. At this time, the fan blades 30 can be impacted, so that the fan blades 30 can rotate. As the fan blades 30 rotate, only by means of the fixing frame 29 can the rotating sleeve 28 be driven to rotate. At this time, the nozzle 31 will make a circular motion, so that the water can be sprayed out through the nozzle 31, and then the inside can be sprayed comprehensively, thus greatly improving the cleaning efficiency and cleaning effect.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
