Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: a liquid dispensing tank for the production of medical injections, comprising a base 1, a mixing barrel 2 is fixedly connected to the top of the base 1, a barrel cover 4 is arranged on the top of the mixing barrel 2, a servo motor 5 is fixedly connected to the middle of the top of the barrel cover 4, the output end of the servo motor 5 passes through the barrel cover 4 and is fixedly connected to a first rotating rod 6, the outer bottom of the first rotating rod 6 is rotatably connected to a hollow column 7, the inner bottom of the hollow column 7 is rotatably connected to a second rotating rod 8, the adjacent ends of the first rotating rod 6 and the second rotating rod 8 are fixedly connected to a first bevel gear 9, the inner right side of the hollow column 7 is rotatably connected to a movable shaft 10, the movable shaft 10 is rotatably connected to the inner right side of the hollow column 7, and the movable shaft 10 is rotatably connected to the inner right side of the hollow column 7. The left end of the shaft 10 is fixedly connected with a second bevel gear 11, and the upper and lower sides of the second bevel gear 11 are respectively meshed with the corresponding first bevel gear 9. A plurality of stirring rods 12 are fixedly connected to the outer sides of the first rotating rod 6 and the second rotating rod 8 at equal intervals, and an arc scraper 13 is fixedly connected to one end of the stirring rod 12. A plurality of cross scrapers 14 are fixedly connected to the outer bottom of the second rotating rod 8 at equal intervals.

A filtering mechanism 3 is arranged on the left side of the top of the barrel cover 4;

[0030] Specifically, when the medicine in the mixing barrel 2 needs to be processed, the first rotating rod 6 is first driven to rotate by the servo motor 5, and the first bevel gear 9 on the first rotating rod 6 will rotate accordingly, thereby driving the second bevel gear 11 on the movable shaft 10 to rotate, and the first bevel gear 9 on the second rotating rod 8 will also rotate. Since the first rotating rod 6 and the second rotating rod 8 have opposite directions, the medicine inside the mixing barrel 2 can be fully mixed. When the first rotating rod 6 and the second rotating rod 8 rotate, the arc scraper 13 and the cross scraper 14 will rotate accordingly to clean the inner wall of the mixing barrel 2. The operation of cleaning the inner wall of the mixing barrel 2 is relatively simple, thereby reducing the workload of the staff. The length of the arc scraper 13 and the cross scraper 14 matches the inner bottom diameter of the mixing barrel 2 to make the scraping work more comprehensive, thereby improving the practicality of the device.

[0031] Reference Figure 1 and Figure 2The filter mechanism 3 includes a liquid inlet 301, which is connected to the left side of the top of the barrel cover 4, a vibration motor 302 is fixedly connected to the front side of the liquid inlet 301, a filter screen 303 is arranged in the middle of the inner side of the liquid inlet 301, and U-shaped plates 304 are fixedly connected to the left and right sides of the top of the filter screen 303, and the two U-shaped plates 304 are threadedly connected to the sides away from each other with a first bolt 305, and one end of the first bolt 305 passes through the U-shaped plate 304 and the liquid inlet 301 in sequence;

[0032] Specifically, the medicine to be processed can be conveniently injected into the mixing barrel 2 through the liquid inlet 301, and the filter 303 can filter out a small amount of impurities in the medicine, thereby improving the subsequent processing quality of the medicine. When the mixing work is completed, the limit on the U-shaped plate 304 can be released by the first bolt 305. At this time, the filter 303 can be conveniently removed from the liquid inlet 301, and the impurities collected by it can be centrally processed.

[0033] Reference Figure 1 and Figure 2 A switch 15 is fixedly connected to the right side of the mixing barrel 2, and the switch 15 is electrically connected to the vibration motor 302 and the servo motor 5 respectively. A protective cover 16 is arranged on the outer side of the switch 15, and the top of the protective cover 16 is rotatably connected to the right side of the base 1 through a rotating shaft;

[0034] Specifically, the operation of the vibration motor 302 and the servo motor 5 can be controlled by the switch 15 , and the protective cover 16 can protect the switch 15 from being damaged by external factors.

[0035] Reference Figure 1 and Figure 2 The left and right sides of the barrel cover 4 are both threadedly connected with a second bolt 17, and one end of the second bolt 17 passes through the barrel cover 4 and the mixing barrel 2 in sequence;

[0036] Specifically, the second bolt 17 can release the limit fixation of the barrel cover 4, and the barrel cover 4 can be removed to maintain the structure at the bottom, thereby improving the practicality of the device.

[0037] Reference Figure 1 The middle part of the bottom end of the mixing barrel 2 is connected with a liquid outlet 18, the bottom of the liquid outlet 18 passes through the base 1 and is provided with a sealing cover 19;

[0038] Specifically, the processed medicine can be conveniently collected through the liquid outlet 18, and the provided sealing cover 19 can prevent the liquid inside the mixing barrel 2 from leaking during the mixing operation.

[0039] Working principle: When using the device, first pour the raw materials of the medicine to be mixed into the mixing barrel 2 through the liquid inlet 301, and the filter screen 303 in the liquid inlet 301 can first filter the impurities in the raw materials of the medicine to be mixed, and the filtered medicine will enter the mixing barrel 2, at this time, the servo motor 5 can drive the first rotating rod 6 to rotate clockwise, and the first bevel gear 9 at the bottom of the first rotating rod 6 will rotate clockwise accordingly, and the second bevel gear 11 inside the hollow column 7 will also rotate due to the engagement with the first bevel gear 9, thereby driving the first bevel gear 9 on the second rotating rod 8 to rotate counterclockwise, and the second rotating rod 8 will rotate counterclockwise accordingly, so that the medicines in the mixing barrel 2 can be mixed more evenly, and the arc scraper 13 and the cross scraper 13 of the first rotating rod 6 and the second rotating rod 8 are rotating at the same time. 14 will rotate to scrape the inner wall of the mixing barrel 2, thereby avoiding a small amount of medicine remaining on the inner wall of the mixing barrel 2 and causing waste. The operation of cleaning the inner wall of the mixing barrel 2 is relatively simple, thereby reducing the workload of the staff and thus improving the work safety of the staff. While pouring the medicine into the mixing barrel 2, the vibration motor 302 is started, and the vibration motor 302 can drive the filter 303 to vibrate, thereby accelerating the filtration speed of the filter 303. After the mixing work is completed, loosening the first bolts 305 on both sides can release the limit on the U-shaped plate 304. At this time, pulling the U-shaped plate 304 upwards can pull the filter 303 out of the liquid inlet 301 for cleaning and replacement. It is relatively simple to disassemble the filter 303, thereby improving the practicality of the device.
