[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0025] like Figures 1 to 5As shown in the embodiment of this utility model, a pharmaceutical mixing device includes a base plate 1; a fixing plate 10 is fixedly connected to the top of the base plate 1; a mixing tank 11 is installed in the middle of the fixing plate 10; a cover plate 12 is installed on the top of the mixing tank 11; a first fixing groove 13 is opened at the bottom of the cover plate 12; the top of the mixing tank 11 is inserted into the middle of the first fixing groove 13; a second fixing groove 14 is opened in the middle of the cover plate 12; fixing blocks 15 are installed on both sides of the second fixing groove 14; the two fixing blocks 15 are arranged opposite each other; a connecting plate 16 is fixedly connected to the ends of the two fixing blocks 15; a motor 17 is fixedly connected to the top of the connecting plate 16; the output end of the motor 17 passes through the middle of the connecting plate 16; the motor 17 outputs... A stirring shaft 18 is fixedly connected to one end; multiple support rods 19 are fixedly connected to the middle of the stirring shaft 18; a hinge seat 20 is fixedly connected to the end of the support rod 19; a stirring blade 21 is fixedly connected to the middle of the hinge seat 20; during operation, the reagent to be stirred is placed inside the mixing tank 11 according to the specified measurement, the mixing tank 11 is placed from the top of the fixing plate 10, and the mixing tank 11 is fixed by the fixing plate 10. Then, the cover plate 12 is inserted into the top of the corresponding mixing tank 11 through the first fixing groove 13, so that the cover plate 12 seals the mixing tank 11. A torsion spring is provided at the connection between the stirring blade 21 and the hinge seat 20. When the stirring shaft 18 is placed from the position of the second fixing groove 14, the stirring blade 21 is rotated so that its middle part fits against the stirring shaft 18. The stirring shaft 18 is then moved from the position of the second fixing groove 14. The second fixing slot 14 is inserted into the mixing tank 11, and the connecting plate 16 is placed in the position corresponding to the second fixing slot 14, so that the fixing blocks 15 on both sides of the connecting plate 16 are aligned with the positions on both sides of the second fixing slot 14. The motor 17 is fixed to the top of the cover plate 12 through the connecting plate 16. When the stirring blade 21 is not compressed, it is ejected by the torsion spring to return to its original position. After the motor 17 is powered on, it is turned on, and the output end of the motor 17 rotates. When the output end of the motor 17 rotates, it drives the stirring shaft 18 to stir the medicine inside the mixing tank 11 through multiple stirring blades 21. After the medicine is stirred, the connecting plate 16 is moved upward to remove the fixing block 15 from the second fixing slot 14. When the stirring blade 21 passes through the middle of the cover plate 12, it is squeezed and subjected to pressure. The pressure-pressurized stirring blades 21 rotate towards the center of the stirring shaft 18, allowing the stirring shaft 18 and multiple stirring blades 21 to be easily removed. After stirring, the stirring shaft 18 and multiple stirring blades 21 can be removed individually for easy cleaning and disinfection. This effectively cleans hard-to-reach gaps and corners on the surface, effectively reducing the formation of residual dead corners on the surface of the stirring shaft 18 and stirring blades 21, reducing bacterial contamination from residues on the surface of the stirring shaft 18 and stirring blades 21, effectively reducing cross-contamination between different batches of drugs, effectively increasing the purity and safety of the drugs, and allowing the stirring shaft 18 and stirring blades 21 to be replaced individually after long-term use due to corrosion and wear, reducing the time and cost waste caused by overall disassembly.
[0026] like Figure 3 and Figure 4 As shown, a cleaning cylinder 22 is fixedly connected to the bottom of the cover plate 12; the stirring shaft 18 is located in the middle of the cleaning cylinder 22; two sets of support plates 23 are fixedly connected to the middle of the cleaning cylinder 22; the two support plates 23 form a group; the two support plates 23 are arranged opposite each other; a brush 24 is fixedly connected to the middle of the support plate 23; during operation, when the stirring shaft 18 is removed, multiple stirring blades 21 first contact the bottom of the cleaning cylinder 22. As the stirring blades 21 continue to move upward, they are subjected to pressure and rotated by the cleaning cylinder 22. After rotating, the stirring blades 21 are in a vertical state. When the multiple stirring blades 21 pass through the two sets of brushes 24, the brushes 24 clean the residual agent on the surface of the stirring blades 21. The multiple brushes 24 promptly remove the agent from the surface of the stirring blades 21, so that the agent on the surface of the stirring blades 21 is directly recycled into the mixing tank 11 after cleaning, reducing the problem of waste caused by agent residue on the surface of the stirring blades 21, and effectively reducing the dripping of residual agent on the surface of the stirring blades 21 outside the stirring area after removal.
[0027] like Figure 1 and Figure 2 As shown, a hot air blower 3 is fixedly connected to the top of the base plate 1; an exhaust pipe 31 is fixedly connected to the end of the hot air blower 3; the middle of the exhaust pipe 31 penetrates the side wall of the fixed plate 10; the middle of the exhaust pipe 31 is located on the inner wall of the fixed plate 10; the exhaust pipe 31 is spirally arranged on the inner wall of the fixed plate 10; multiple exhaust holes 32 are opened in the middle of the exhaust pipe 31; during operation, in a low-temperature environment, when the agent is stirred inside the mixing tank 11, the hot air blower 3 is turned on after being powered on, and the hot air is discharged into the exhaust pipe 31 through the hot air blower 3. The hot air passes through multiple exhaust holes 32 inside the exhaust pipe 31. The hot air is discharged through the exhaust vent 32 and stored inside the fixed plate 10. The heat is then transferred to the surface of the mixing tank 11, causing the temperature of the medicine inside the mixing tank 11 to rise. The hot air is discharged into the fixed plate 10 through multiple exhaust vents 32, which can heat the medicine inside the mixing tank 11, making the medicine inside the mixing tank 11 heated evenly, effectively promoting the mixing of the medicine, and making the dissolution or reaction of the medicine more complete and faster, effectively improving the activity of the medicine. By adjusting the temperature and flow rate of the hot air, the heating temperature of the medicine can be precisely controlled, thereby improving the quality of product mixing.
[0028] like Figure 3 , Figure 4 , Figure 6As shown, two fixing rods 4 are fixedly connected to the bottom of the cleaning cylinder 22; the two fixing rods 4 are inclined; the two fixing rods 4 are arranged opposite each other; a roller 41 is rotatably connected to the end of the fixing rod 4; during operation, when the stirring blade 21 passes through the inside of the cleaning cylinder 22 for cleaning, it first contacts one side of the stirring blade 21 through the roller 41. As the stirring blade 21 continues to move and rotate, the roller 41 rotates at the same time. The roller 41 reduces the direct contact between the stirring blade 21 and the cleaning cylinder 22 when the stirring blade 21 moves upward, effectively reducing the friction generated when the stirring blade 21 contacts the cleaning cylinder 22 and moves upward, reducing the wear caused by friction between the stirring blade 21 and the cleaning cylinder 22, and effectively making the stirring blade 21 move upward more smoothly.
[0029] like Figure 1 , Figure 3 , Figure 5 As shown, two elastic plates 5 are fixedly connected to the bottom of the cover plate 12; a sealing strip 51 is fixedly connected to the end of each elastic plate 5. During operation, when the cover plate 12 is placed on top of the mixing tank 11, the mixing tank 11 is inserted between the two elastic plates 5. The two elastic plates 5 are elastically bent by the pressure from both sides of the mixing tank 11 and are in contact with the side wall of the mixing tank 11 through the sealing strip 51. The sealing strip 51 can effectively make the end of the elastic plate 5 fit with the side wall of the mixing tank 11. The sealing strip 51 can effectively reduce the leakage of the agent between the cover plate 12 and the mixing tank 11 during the stirring process, and effectively reduce the entry of impurities in the outside air into the mixing tank 11, thus effectively maintaining the purity of the mixing tank 11.
[0030] like Figure 1 , Figure 3 , Figure 5 As shown, a handle 6 is fixedly attached to the top of the connecting plate 16; an anti-slip pad 61 is fixedly attached to the middle of the handle 6; when working, when taking out the stirring shaft 18, hold the anti-slip pad 61, so that your fingers fit into the concave part of the anti-slip pad 61, and lift the stirring shaft 18 through the handle 6 and take it out from inside the mixing tank 11. The handle 6 makes it more convenient and faster to put in and take out the stirring shaft 18 and the stirring blade 21, reducing the time spent using additional tools. The anti-slip pad 61 can effectively increase the friction between the hand and the handle 6, reducing the risk of slipping and falling or colliding during operation.
[0031] like Figure 2As shown, a rubber pad 7 is fixedly connected to the middle of the fixing plate 10; the rubber pad 7 is fixed near the top of the fixing plate 10; during operation, when the mixing tank 11 is placed in the middle of the fixing plate 10, it is in contact with the outer wall of the mixing tank 11 through the rubber pad 7. When the mixing tank 11 is placed inside the fixing plate 10, the rubber pad 7 is squeezed by the mixing tank 11 and undergoes flexible contraction. The elasticity of the rubber pad 7 has good shock absorption performance, which can effectively absorb the vibration and impact generated during the mixing process, effectively reduce the wear and damage caused by vibration between the mixing tank 11 and the fixing plate 10, and effectively fill the small gap between the fixing plate 10 and the mixing tank 11, effectively increasing the stability of the mixing tank 11 inside the fixing plate 10.
[0032] During operation, the required reagent is placed inside the mixing tank 11 according to the specified measurement. The mixing tank 11 is then inserted from the top of the fixing plate 10 and fixed in place by the fixing plate 10. The cover plate 12 is then inserted into the top of the mixing tank 11 through the first fixing groove 13 to seal the mixing tank 11. A torsion spring is provided at the connection between the stirring blade 21 and the hinge seat 20. When the stirring shaft 18 is placed from the second fixing groove 14, the stirring blade 21 is rotated so that its center is in contact with the stirring shaft 18. The stirring shaft 18 is then inserted into the mixing tank 11 from the second fixing groove 14. The connecting plate 16 is then inserted into the second fixing groove 14, with the fixing blocks 15 on both sides of the connecting plate 16 corresponding to the positions on both sides of the second fixing groove 14. 6. Fix the motor 17 to the top of the cover plate 12. When the stirring blades 21 are not compressed, they will pop out and return to their original position via the torsion spring. After the motor 17 is powered on, it will rotate. When the motor 17 rotates, it will drive the stirring shaft 18 to stir the medicine inside the mixing tank 11 through the multiple stirring blades 21. After the medicine is stirred, move the connecting plate 16 upward to remove the fixing block 15 from the second fixing groove 14. When the stirring blades 21 pass through the middle of the cover plate 12, they will be squeezed. The stirred blades 21 under pressure will rotate towards the middle of the stirring shaft 18, so that the stirring shaft 18 and the multiple stirring blades 21 can be easily removed. When the stirring shaft 18 is removed, the multiple stirring blades 21 will first contact the bottom of the cleaning cylinder 22. When the stirring blades... During the upward movement of the mixing drum 21, the stirring blades 21 are subjected to pressure and rotated by the cleaning cylinder 22. After rotation, the stirring blades 21 are in a vertical position. When multiple stirring blades 21 pass through two sets of brushes 24, the brushes 24 clean the residual agent on the surface of the stirring blades 21. In a low-temperature environment, when the agent is stirred inside the mixing drum 11, the hot air blower 3 is turned on and hot air is discharged into the exhaust pipe 31. The hot air is discharged through multiple exhaust holes 32 inside the exhaust pipe 31 and stored inside the fixed plate 10. The heat is then transferred to the surface of the mixing drum 11, causing the temperature of the agent inside the mixing drum 11 to rise. When the stirring blades 21 pass through the cleaning cylinder 22 for cleaning, they are first cleaned by the roller 41. Side contact: As the stirring blade 21 moves and rotates, the drum 41 rotates simultaneously. When the cover plate 12 is placed on top of the mixing tank 11, the mixing tank 11 is inserted between two elastic plates 5. The two elastic plates 5 are squeezed by the sides of the mixing tank 11 and bend elastically. They are attached to the side wall of the mixing tank 11 through the sealing strip 51. When the stirring shaft 18 is removed, hold the anti-slip pad 61 and make your fingers fit into the concave part of the anti-slip pad 61. Use the handle 6 to lift the stirring shaft 18 and remove it from the inside of the mixing tank 11. When the mixing tank 11 is placed in the middle of the fixing plate 10, it is attached to the outer wall of the mixing tank 11 through the rubber pad 7. When the mixing tank 11 is placed inside the fixing plate 10, the rubber pad 7 is squeezed by the mixing tank 11 and shrinks flexibly.
