Description

Technical Field

[0001] This utility model relates to the field of stirring device technology, specifically a stirring device for tablet coating liquid. Background Technology

[0002] Tablet coating solution is a key material used for surface coating in tablet production. Its components typically include film-forming materials, solvents, plasticizers, and pigments, which need to be stirred to form a uniform and stable dispersion system. The tablet coating solution stirring device is a specialized piece of equipment used to prepare and process tablet coating solutions. Its core function is to use mechanical stirring to uniformly mix the various components (such as polymers, pigments, plasticizers, solvents, etc.) in the coating solution, forming a stable and homogeneous dispersion system, thus providing qualified coating material for subsequent tablet coating processes.

[0003] Based on the above, the inventors have discovered the following problems: Currently, the stirring blades and shafts of most stirring devices are rigidly connected, and the angle is not adjustable. For low-viscosity coating solutions, such as water-soluble coating solutions, the fixed-angle stirring blades easily generate localized eddies, resulting in low mixing efficiency. For high-viscosity coating solutions, such as slow-release coating solutions containing a large number of solid particles, it is difficult to provide sufficient shear force to break up particle agglomeration. Furthermore, the viscosity of coating solutions with different formulations varies significantly, requiring the replacement of different stirring components to adapt to materials of different viscosities, which is cumbersome and time-consuming.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a tablet coating liquid stirring device in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this invention is to provide a tablet coating liquid stirring device to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows: A tablet coating liquid stirring device includes a main body and a stirring assembly. The stirring assembly includes a pair of stirring columns arranged sequentially from top to bottom and welded together. Four pairs of support plates are welded circumferentially to the outside of each stirring column. A rotating shaft is rotatably connected between the pair of support plates. A support rod is installed at the center of one side of the outer wall of the rotating shaft. A stirring blade is installed at the end of the support rod away from the rotating shaft. A pair of connecting plates are installed on the outer wall of the rotating shaft opposite to the support rod. A connecting rod is rotatably connected between the pair of connecting plates. Four first grooves are formed circumferentially on the outer wall of the stirring column. A first magnetic ball is slidably connected inside the first groove. The outer wall of the first magnetic ball is fixedly connected to the end of the connecting rod away from the connecting plate.

[0007] Furthermore, the inner wall of the stirring column is provided with four second grooves along the circumference, and the four second grooves correspond one-to-one with the four first grooves. Each of the four second grooves is slidably connected with a second magnet ball, and adjacent first magnet balls and second magnet balls are magnetically attracted to each other.

[0008] The beneficial effect of adopting the above-mentioned further solution is that by setting a first magnetic ball in the first groove of the stirring column and a second magnetic ball in the second groove, and the two magnetically attracting each other, a non-contact force transmission structure is formed: when the second magnetic ball moves, it can drive the first magnetic ball to slide synchronously through magnetic force, and the connecting rod fixedly connected to the first magnetic ball moves together. Since the end of the connecting rod away from the first magnetic ball is rotatably connected to a pair of connecting plates on the rotating shaft, the movement of the connecting rod will be converted into a pushing or pulling force on the connecting plates, forcing the rotating shaft to rotate clockwise or counterclockwise around its own axis, thereby enabling the stirring blades to perform stepless adjustment of the upward or downward angle; when the second magnetic ball moves upward, the first magnetic ball moves in a parallel motion, and the first magnetic ball moves in a parallel motion, the first magnetic ball moves in a parallel motion, and the second ... The iron ball moves upward synchronously, the connecting rod pulls the connecting plate, the rotating shaft rotates clockwise, and the stirring blade flips upward, increasing the angle. When the second magnet ball moves downward, the first magnet ball moves downward synchronously, the connecting rod pushes the connecting plate, the rotating shaft rotates counterclockwise, and the stirring blade flips downward, decreasing the angle. Both the first and second magnet balls are neodymium iron boron strong magnets with a magnetic force level of N35 or higher. When the stirring device is working, the high-speed rotation of the stirring column will generate vibration, and the collision of particles in the coating liquid may also impact the stirring blade. The strong magnetic force of N35 or higher can form rigid magnetic coupling, reducing magnetic fluctuations caused by vibration, and preventing the first and second magnet balls from momentarily separating or misaligning due to vibration, thus ensuring the continuity of transmission.

[0009] Furthermore, an electric slide rail is installed inside the stirring column, and an electric slider is slidably connected to the outside of the electric slide rail. A disc is fitted around the outside of the electric slider, and an installation groove is opened at the center of the disc. The inner wall of the installation groove is fixedly connected to the outer wall of the electric slider. Four pillars are installed circumferentially on the outer wall of the disc, and the four pillars are fixedly connected to the outer wall of four second magnet balls at the ends away from the disc.

[0010] The beneficial effect of adopting the above-mentioned further solution is that, by setting up electric slide rails, since there are two stirring columns, that is, two electric slide rails, the two electric slide rails drive the electric slider to move in the same direction and at the same speed; the electric slide rails drive the electric slider to move axially, driving the disc and the support column to move synchronously, and then the support column pushes the second magnet ball to slide in the second groove, realizing precise control of the position of the second magnet ball, and precisely adjusting the position of the first magnet ball through magnetic linkage, ultimately realizing stepless adjustment of the stirring blade angle, such as locking any angle from 30 degrees to 60 degrees, adapting to the stirring needs of low viscosity to ultra-high viscosity coating liquids.

[0011] Furthermore, a transmission column is welded and fixed to one end of each pair of stirring columns facing away from each other, and the cross-section of the two transmission columns is a regular hexagon.

[0012] Furthermore, the main body includes a cylindrical body, the upper end of which is provided with a cylindrical cover, a first circular hole is provided at the center of the bottom end of the cylindrical body, and a second circular hole is provided at the center of the inner part of the cylindrical cover. Both the first and second circular holes are rotatably connected to transmission sleeves, and the two transmission sleeves are provided with transmission grooves inside.

[0013] The beneficial effect of adopting the above-mentioned further solution is that, since the transmission column is hexagonal and cooperates with the transmission groove, it can stably transmit torque; when the transmission rods at the bottom of a pair of stirring columns are inserted into the transmission sleeves at the bottom of the cylinder, and then the cylinder cover is closed, the transmission rods at the top of a pair of stirring columns are inserted into the transmission sleeves on the cylinder cover; when the transmission sleeves on the cylinder cover rotate, the torque is transmitted under the cooperation of the transmission column, causing the stirring assembly to rotate as a whole to achieve stirring.

[0014] Furthermore, the two transmission columns are located in the two transmission slots respectively, and the outer walls of the two transmission columns are in sliding fit with the inner walls of the two transmission slots.

[0015] The advantages of adopting the above-mentioned further solution are that the outer wall of the transmission column slides with the inner wall of the transmission groove, the stirring component can be quickly installed and removed along the axial direction, and it is easy to clean; the shape of the transmission groove matches the regular hexagonal transmission column, ensuring efficient power transmission and avoiding energy loss.

[0016] Furthermore, a servo motor is installed at the center of the top surface of the cylinder cover, and the output end of the servo motor is connected to one of the transmission sleeves. Several first screw holes are equally spaced inside the top surface of the cylinder, and a second screw hole is opened inside the cylinder cover near the first screw hole. Bolts are threadedly connected between adjacent first screw holes and second screw holes.

[0017] The advantages of adopting the above-mentioned further solution are that the servo motor provides power to the stirring assembly; the bolts fix the cover and the cylinder body, and the bolt connection ensures the sealing performance of the cover and the cylinder body, while also facilitating disassembly and cleaning.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: This tablet coating liquid stirring device, by setting a first magnetic ball in the first groove of the stirring column and a second magnetic ball in the second groove, and the two magnetically attract each other, forms a non-contact force transmission structure: when the second magnetic ball moves, it can drive the first magnetic ball to slide synchronously through magnetic force, and the connecting rod fixedly connected to the first magnetic ball moves together. Since the end of the connecting rod away from the first magnetic ball is rotatably connected to a pair of connecting plates on the rotating shaft, the movement of the connecting rod will be converted into a pushing or pulling force on the connecting plates, forcing the rotating shaft to rotate clockwise or counterclockwise around its own axis, thereby enabling the stirring blade to perform stepless adjustment of the upward or downward angle; adapting to the stirring needs of low viscosity to ultra-high viscosity coating liquids.

[0021] 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.

[0022] Please see Figures 1-5This utility model provides a technical solution: a tablet coating liquid stirring device, comprising a main body 1 and a stirring assembly 2. The stirring assembly 2 includes a pair of stirring columns 21, which are arranged sequentially from top to bottom and welded together. Four pairs of support plates 22 are welded circumferentially to the outside of the stirring columns 21. A rotating shaft 23 is rotatably connected between the pair of support plates 22. A support rod 24 is installed at the center of one side of the outer wall of the rotating shaft 23. A stirring blade 25 is installed at the end of the support rod 24 away from the rotating shaft 23. A pair of connecting plates 26 are installed on the outer wall of the rotating shaft 23 opposite to the support rod 24. The pair of connecting plates 26 are rotatably connected between the two sides. The stirring column 21 is dynamically connected by a connecting rod 27. Four first grooves 28 are circumferentially formed on the outer wall of the stirring column 21. First magnetic balls 210 are slidably connected inside the first grooves 28. The outer wall of the first magnetic balls 210 is fixedly connected to the end of the connecting rod 27 away from the connecting plate 26. Four second grooves 29 are circumferentially formed on the inner wall of the stirring column 21, each corresponding to one of the four first grooves 28. Second magnetic balls 211 are slidably connected inside each of the four second grooves 29. Adjacent first magnetic balls 210 and second magnetic balls 211 are magnetically attracted to each other. An electric slide rail 212 is installed inside the stirring column 21. An electric slider 213 is slidably connected to the outside of the electric slide rail 212. A disc 214 is fitted around the outside of the electric slider 213. A mounting groove is formed at the center of the disc 214, and the inner wall of the mounting groove is fixedly connected to the outer wall of the electric slider 213. Four supports are mounted circumferentially on the outer wall of the disc 214. The four supports are fixedly connected to the outer wall of four second magnetic balls 211 at their ends away from the disc 214. The electric slide rail 212 drives the electric slider 213 to move axially, causing the disc 214 and the supports to move synchronously. This, in turn, pushes the second magnetic balls 211 to slide within the second groove 29 through the supports, realizing the second magnetic... The precise control of the position of the iron ball 211 is achieved by precisely adjusting the position of the first magnetic ball 210 through magnetic linkage. When the second magnetic ball 211 moves, the first magnetic ball 210 can be driven to slide synchronously through magnetic force. The connecting rod 27, which is fixedly connected to the first magnetic ball 210, moves along with it. Since the end of the connecting rod 27 away from the first magnetic ball 210 is rotatably connected to a pair of connecting plates 26 on the rotating shaft 23, the movement of the connecting rod 27 will be converted into a pushing or pulling force on the connecting plates 26, forcing the rotating shaft 23 to rotate clockwise or counterclockwise around its own axis, thereby enabling the stirring blade 25 to perform stepless adjustment of the upward or downward angle.

[0023] 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.

[0024] Please see Figures 1-5 This utility model provides a technical solution: A pair of stirring columns 21 each have a transmission column 215 welded and fixed to one end facing away from each other. The cross-section of the two transmission columns 215 is a regular hexagon. The main body 1 includes a cylinder 11, with a cylinder cover 12 at the upper end. A first circular hole is opened at the center of the bottom end of the cylinder 11, and a second circular hole is opened at the center of the cylinder cover 12. Transmission sleeves 13 are rotatably connected to both the first and second circular holes. Transmission grooves are opened inside the two transmission sleeves 13. The two transmission columns 215 are respectively located in the two transmission grooves. The outer walls of the two transmission columns 215 slide against the inner walls of the two transmission grooves. A servo motor 14 is installed at the center of the top surface of the cylinder cover 12. The output end of the servo motor 14 is connected to one of the transmission sleeves 13. A plurality of second transmission columns 11 are equidistantly opened inside the top surface of the cylinder 11. A screw hole is provided inside the cylinder cover 12, near the first screw hole. A bolt is threaded between the adjacent first and second screw holes. When the transmission rods at the bottom of the pair of stirring columns 21 are inserted into the transmission sleeves 13 at the bottom of the cylinder 11, and then the cylinder cover 12 is closed, the transmission rods at the top of the pair of stirring columns 21 are inserted into the transmission sleeves 13 on the cylinder cover 12. The servo motor 14 starts and drives the transmission sleeves 13 on the cylinder cover 12 to rotate. With the cooperation of the transmission column 215, the torque is transmitted to make the stirring assembly 2 rotate as a whole to achieve stirring. The bolts fix the cylinder cover 12 and the cylinder 11. The bolt connection ensures the sealing performance of the cylinder cover 12 and the cylinder 11, and facilitates disassembly and cleaning. When the stirring assembly 2 needs to be disassembled, the bolts are removed and the cylinder cover 12 is taken off. The outer wall of the transmission column 215 slides with the inner wall of the transmission groove, and the stirring assembly 2 is quickly disassembled along the axial direction.

[0025] Specifically, the working principle of this tablet coating solution stirring device is as follows: During use, the required solvent is poured into the cylinder 11. The transmission rods at the bottom of the pair of stirring columns 21 are inserted into the transmission sleeves 13 at the bottom of the cylinder 11. Then, the cylinder cover 12 is closed, allowing the transmission rods at the top of the pair of stirring columns 21 to insert into the transmission sleeves 13 on the cylinder cover 12, and bolts are installed. The electric slide rail 212 drives the electric slider 213 to move axially, causing the disc 214 and support column to move synchronously. This, in turn, pushes the second magnetic ball 211 to slide within the second groove 29 via the support column, achieving precise control of the position of the second magnetic ball 211. The position of the first magnetic ball 210 is precisely adjusted through magnetic linkage. When the second magnetic ball 211 moves, it can be adjusted by magnetic force. The first magnetic ball 210 slides synchronously, and the connecting rod 27, which is fixedly connected to the first magnetic ball 210, moves along with it. Since the end of the connecting rod 27 away from the first magnetic ball 210 is rotatably connected to a pair of connecting plates 26 on the rotating shaft 23, the movement of the connecting rod 27 will be converted into a pushing or pulling force on the connecting plates 26, forcing the rotating shaft 23 to rotate clockwise or counterclockwise around its own axis, thereby allowing the stirring blade 25 to be infinitely adjusted up or down. The servo motor 14 starts to drive the transmission sleeve 13 on the cylinder cover 12 to rotate, and with the cooperation of the transmission column 215, it transmits torque to make the stirring assembly 2 rotate as a whole to achieve stirring. After stirring is completed, the user holds the cylinder 11 to pour the mixed coating liquid.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.
