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.

[0020] 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.

[0021] Reference Figure 1-4 A vacuum ointment making machine that can be cleaned online includes a tank body 1, a tank cover 2 on the top of the tank body 1, a stirring shaft 3 at the center of the inside of the tank body 1, and scraping shafts 4 symmetrically arranged on the left and right sides of the stirring shaft 3. Two sets of outwardly extending cylinders 6 are arranged on the tank cover 2 on the front and rear sides of the stirring shaft 3, and a set of spray balls 5 that move up and down along the cylinder 6 are installed inside the cylinder 6.

[0022] Through this technical solution, the vacuum ointment making machine adopts a full curvature shell design. The tank body 1 and the tank cover 2 form a sealed pressure boundary, and its inner wall is a continuous curved surface without dead angles. A high-strength titanium alloy stirring shaft 3 is installed through the center of the tank body 1. The shaft penetrates the tank cover 2 and is connected to the drive system via a magnetic sealing device. A stirring paddle is installed on the stirring shaft 3 for stirring. Planetary scraping shafts 4 are symmetrically arranged on the left and right sides of the stirring shaft 3. Scrapers that conform to the curved surface of the tank wall are connected to the scraping shafts 4. An outer extension cylinder 6 is integrated on the top of the tank cover 2 on both the front and rear sides of the stirring shaft 3. The diameter of the cylinder 6 is equipped with a liftable spray ball 5 assembly. The spray ball 5 is driven by a servo electric cylinder to rise and fall along the axial direction of the cylinder 6. When the spray ball 5 rises into the cylinder 6, the nozzle on the spray ball 5 can cover the top of the ointment making machine. The connection between the cylinder 6 and the tank cover 2 is laser welded to ensure vacuum sealing. The spray ball 5 passes through the top of the cylinder 6 and is sealed.

[0023] Furthermore, the rear end of the spray ball 5 is connected to a tube shaft 7, which is a hollow structure and conveys the cleaning medium to the spray ball 5. The rear end of the tube shaft 7 is connected to a lifting device 9, which drives the tube shaft 7 and the spray ball 5 to move up and down along the cylinder 6.

[0024] Furthermore, the diameter of the spray ball 5 is the same as the diameter of the cylinder 6. Several sets of spray nozzles are provided on the spray ball 5. A guide rod 11 is provided on the inner wall of the cylinder 6. A sliding sleeve 10 that cooperates with the guide rod 11 is provided on the pipe shaft 7. A set of baffles 8 is also provided between the pipe shaft 7 and the spray ball 5. The baffles 8 are consistent with the opening of the cylinder 6.

[0025] Through this technical solution, the hollow tube shaft 7 and the spherical spray head form a precision motion mechanism. The tube shaft 7 is made of stainless steel tube, and its rear end is connected to the servo electric push rod of the lifting device 9 through a flange. The front end is welded with argon arc welding to the base of the spray ball 5. The outer diameter of the spray ball 5 is precisely matched with the inner diameter of the cylinder 6 to achieve clearance fit. The sliding sleeve 10 of the tube shaft 7 and the guide rod 11 on the inner wall of the cylinder 6 can achieve precise guidance. With the precise control of the servo electric push rod, the spray ball 5 can be driven to perform high-precision lifting and lowering movements, thereby hiding part of the spray ball 5 inside the cylinder 6. Several swirling spray nozzles are evenly distributed on the surface of the ball. When part of the structure of the spray ball 5 is hidden inside the cylinder 6, the nozzles of the spray ball 5 can shoot high-pressure water flow towards the top of the ointment making machine, thereby ensuring coverage and avoiding cleaning dead corners.

[0026] The baffle 8 is aligned with the opening of the cylinder 6, thus forming a certain barrier to prevent materials from directly entering the interior of the cylinder 6. When the tube shaft 7 is driven to rise by the lifting device 9, the baffle 8 extends into the interior of the cylinder 6 and is stopped when it contacts the guide rod 11, thereby preventing the spray ball 5 from going too deep into the interior of the cylinder 6.

[0027] Furthermore, the cylinder 6 is a sealed structure.

[0028] The cylinder body 6 is welded to the can lid 2 to ensure the sealing of the connection between the cylinder body 6 and the can lid 2. The cylinder lid at the upper end of the cylinder body 6 is integrally connected to the cleaning liquid inlet pipe used for inputting the cleaning medium, thereby ensuring the sealing of the entire ointment making machine system so as to maintain the vacuum environment required during operation.

[0029] Furthermore, the tank body 1 is a fully curved shell, and the inner wall of the tank body 1 and the bottom surface of the tank cover 2 are both mirror polished.

[0030] The tank body 1 is a fully curved shell, generally spherical or ellipsoidal. The fully curved shell ensures that there are no straight edges inside the tank body 1, thereby reducing the adhesion points of materials, reducing cleaning dead corners, and improving the cleaning effect. The inner wall of the tank body 1 and the bottom surface of the tank cover 2 are mirror polished, which reduces surface roughness and facilitates scraping the wall and cleaning the tank body 1.

[0031] Furthermore, a hydraulic cylinder is installed above the tank cover 2, and a vacuum system is also connected to the tank cover 2. A discharge butterfly valve is connected to the bottom of the tank body 1.

[0032] With this technical solution, the hydraulic cylinder is a synchronous hydraulic cylinder to drive the stirring shaft 3 and the scraping shaft 4 to move; the vacuum system is used to maintain a vacuum sealed environment inside the ointment making machine, thereby eliminating the influence of air bubbles in the material mixing process. After the mixing process is completed, the material is discharged from the discharge butterfly valve at the bottom of the tank.

[0033] Working Principle: This solution's ointment-making machine cleaning includes two modes: bottom cleaning and top cleaning. In bottom cleaning mode, the spray ball 5 sprays cleaning liquid into the tank 1. The pressurized, high-speed spray, combined with the movement of the stirring shaft 3 and the scraping shaft 4, peels the material adhering to the inner wall of the tank 1 from the inner wall, thus cleaning the inner wall of the tank 1. At this time, due to the position limitation of the tube shaft 7, the spray ball 5 cannot fully clean the top of the ointment-making machine, forming a cleaning dead zone at the top of the ointment-making machine. In bottom cleaning mode, the lifting device 9 drives the spray ball 5 to rise from the bottom. The tube shaft 7 and part of the spray ball 5 are inserted into the interior of the cylinder 6. Since the nozzles on the spray ball 5 are no longer limited from above, they can fully cover the top of the ointment making machine, thus eliminating cleaning dead corners and effectively cleaning the top of the vacuum ointment making machine. The two modes of the spray ball 5 work together to effectively clean the vacuum ointment making machine, reduce cross-contamination of media, ensure the safety of the finished product, and improve cleaning efficiency through automated spraying, which is conducive to improving processing efficiency and has better performance.
