Description

Technical Field

[0001] This utility model relates to the field of medicinal material processing technology, and in particular to a multifunctional extraction tank stirring paddle anti-winding device. Background Technology

[0002] Multifunctional extraction tanks are core equipment used in the pharmaceutical, food, and chemical industries to extract active ingredients from natural materials. Their core function is to achieve the penetration, dissolution, and separation of materials by solvents through heating, stirring, and circulation. The stirring paddle is used to avoid excessively high or low concentrations in certain areas and to ensure consistent extraction.

[0003] In existing technologies, the commonly used stirring paddles are usually long rod-shaped. Pharmaceutical extraction tanks often use plant materials such as roots and stems, fibers, or polymeric excipients such as cellulose and starch. During the stirring process, these materials are prone to forming fiber clumps or particle agglomerates due to shear force, which can become entangled on the stirring paddle and cause it to jam. This requires stopping the machine to clean the stirring paddle, which delays the stirring and pharmaceutical production time and reduces pharmaceutical efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multifunctional anti-winding device for the stirring paddle of an extraction tank.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multifunctional extraction tank stirring paddle anti-winding device, including a rotating shaft, the rotating shaft having a heat dissipation channel inside, and multiple stirring shell rods fixedly connected to the outside of the rotating shaft, with a cutting component inside the stirring shell rod; The cutting assembly includes a stepper motor, which is fixedly installed inside the stirring shell rod. Limit guide grooves are provided on both sides of the inner wall of the stirring shell rod. A movable column is slidably connected inside the stirring shell rod. Guide blocks are fixedly connected to both sides of the movable column. A lead screw is fixedly connected to the output end of the stepper motor.

[0006] As a further description of the above technical solution: The guide block is slidably connected inside the limiting guide groove. The moving column has a threaded groove inside. The lead screw is threaded inside the threaded groove. Mounting rods are fixedly connected to both sides of the moving column. Cutting blades are provided at one end of the two mounting rods and on both sides of the stirring shell rod.

[0007] As a further description of the above technical solution: One end of the rotating shaft is fixedly connected to a heat sink, and a connecting shell is fixedly connected to the upper surface of the heat sink. Multiple heat dissipation holes are provided on the outside of the heat sink.

[0008] As a further description of the above technical solution: Mounting assemblies are provided at one end of each of the two mounting rods and on both sides of the stirring shell rod. Each mounting assembly includes a fixing box, and a bracket is slidably connected inside the fixing box.

[0009] As a further description of the above technical solution: Multiple fixing boxes are respectively fixedly connected to one end of multiple mounting rods and both sides of multiple stirring shell rods, and the insert is fixedly connected to one side of the cutting blade.

[0010] As a further description of the above technical solution: The fixing box has through holes on both sides, and the insert has a through hole in the middle.

[0011] As a further description of the above technical solution: The through hole and two of the through holes are internally slidably connected to a locking pin. One end of the locking pin is fixedly connected to a limit block, and the other end of the locking pin is fixedly connected to a stud. The stud is externally threaded with a threaded sleeve.

[0012] This utility model has the following beneficial effects: 1. This utility model, through the setting of the cutting component, utilizes the proximity of two cutting blades on the same side to generate shearing force, which helps to cut the roots and stems wrapped around the stirring shell rod, thereby helping to reduce the phenomenon of roots and stems wrapping around the stirring shell rod. Furthermore, when the moving column moves into the stirring shell rod, the roots and stems wrapped around the outside of the moving column will be pushed away by the limiting on one side of the stirring shell rod, thus reducing the roots and stems wrapping around the outside of the moving column and also reducing the roots and stems wrapping around the stirring shell rod.

[0013] 2. By setting up the installation components, this utility model allows the locking pin to be pulled out of the through hole and the bracket to be pulled out of the fixing box, making it easy to remove the cutting blade from the outside of the fixing box. This facilitates the timely replacement of damaged cutting blades when they become damaged or dull, and helps maintain the anti-tangling function of the cutting components.

A moving column 6 is slidably connected inside the stirring shell rod 3. The moving column 6 is in a close fit when sliding inside the stirring shell rod 3. Guide blocks 8 are fixedly connected on both sides of the moving column 6. A lead screw 22 is fixedly connected to the output end of the stepper motor 4.

[0018] As attached Figure 5 As shown, the guide block 8 is slidably connected inside the limiting guide groove 5, which plays a limiting and guiding role for the moving column 6. The moving column 6 has a threaded groove 7 inside, which matches the thread of the lead screw 22. The lead screw 22 is threadedly connected inside the threaded groove 7. Cutting blades 12 are provided at one end of the two mounting rods 9 and on both sides of the stirring shell rod 3.

[0019] As attached Figure 6 As shown, mounting rods 9 are fixedly connected to both sides of the movable column 6, which are used to install and drive the cutting blade 12 to move.

[0020] As attached Figure 2As shown, a heat sink 19 is fixedly connected to one end of the rotating shaft 1, and a connecting shell 20 is fixedly connected to the upper surface of the heat sink 19. Multiple heat dissipation holes 21 are provided on the outside of the heat sink 19 to facilitate the heat dissipation of the stepper motor 4.

[0021] As attached Figure 3 As shown, mounting components are provided at one end of the two mounting rods 9 and on both sides of the stirring shell rod 3. The mounting components include a fixing box 10, which facilitates the indirect mounting of the cutting blade 12. The fixing box 10 has a sliding bracket 11 inside, which facilitates the installation of the cutting blade 12. Multiple fixing boxes 10 are respectively fixedly connected to one end of multiple mounting rods 9 and both sides of multiple stirring shell rods 3, so that one side of the cutting blade 12 is in a fixed state and the other side of the cutting blade 12 is in a translational state. The bracket 11 is fixedly connected to one side of the cutting blade 12.

[0022] As attached Figure 6 As shown, through holes 13 are provided on both sides of the fixing box 10 to facilitate the passage of the locking pin 15.

[0023] As attached Figure 7 As shown, a through hole 14 is provided in the middle of the insert 11. A locking pin 15 is slidably connected inside the through hole 14 and two of the through holes 13, which limits the position of the insert 11. A limit block 16 is fixedly connected to one end of the locking pin 15, which limits the position of one end of the locking pin 15.

[0024] Working principle: When in use, first connect the connecting shell 20 to the drive end, and place the whole unit inside the extraction tank. During stirring, the drive end will drive the rotating shaft 1 to rotate, which in turn drives multiple stirring shell rods 3 and moving column 6 to revolve and stir. When plant roots and stems are wrapped around the stirring shell rods 3 and moving column 6, the external controller controls the output ends of multiple stepper motors 4 to rotate, which drives the lead screw 22 to rotate. With the connection of the threaded groove 7, the moving column 6 is pushed to slide and retract inside the stirring shell rod 3 through the thread. At this time, the guide block 8 will slide inside the limiting guide groove 5. When the moving column 6 retracts, it will block the plant roots and stems wrapped around the outside of the moving column 6 under the limiting on one side of the stirring shell rod 3, and push the plant roots and stems away from the outside of the moving column 6. At the same time, the moving column 6 will drive the cutting blade 12 installed therein to move closer to the cutting blade 12 fixed on the other side through the mounting rod 9. When the two cutting blades 12 are close together, the wrapped plant roots and stems and herbs are cut off, and the herbs are unwrapped outside the stirring shell rod 3. When some of the cutting blades 12 are damaged, remove the entire device from the extraction tank, then unscrew the threaded sleeve 18 under the cutting blade 12 that needs to be replaced, unscrew the threaded sleeve 18 out of the corresponding stud 17, so that the locking pin 15 is released from its limit. Then, pull the locking pin 15 out of the through hole 14 and through hole 13, so that the insert 11 is released from its limit. Then, pull the insert 11 out of the fixing box 10, thereby removing the cutting blade 12. The new cutting blade 12 is first connected to the insert 11, and then the above method is reversed to install and lock the cutting blade 12, and then put it into use.
