[0002] Pharmaceutical production organizations need to use drug dispensing devices. The existing solid-liquid dispensing devices put solid and liquid drugs into a mixing tank for mixing. When there is too much liquid drug, the liquid drug can only be quantitatively proportioned through the drug outlet pipe at the bottom of the tank. It is not easy to control the outflowing liquid drug, and the drug between the upper and lower stirring rods is not easy to be stirred, resulting in reduced mixing efficiency. For this reason, we propose an adjustable quantitative centralized liquid dispensing device. Utility Model Content

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of this patent to clearly and completely describe the technical solutions in the embodiments of this patent. Obviously, the described embodiments are only part of the embodiments of this patent, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0018] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The present invention provides a technical solution: an adjustable quantitative centralized liquid dispensing device, comprising a tank body 1, a liquid return tank 3 and a fixed ring 17, a sliding hole is provided on the top of the tank body 1, an observation window 2 is embedded in the left wall of the tank body 1, and a scale line is provided on the observation window 2, a pump body 4 is fixedly installed on the left side of the top of the liquid return tank 3, the input end of the pump body 4 is connected to one end of a liquid return pipe 5, the other end of the liquid return pipe 5 passes through the top of the tank body 1 and is connected to a hose 6, the bottom end of the hose 6 is fixedly connected to a connecting ring 7, the left end of the connecting ring 7 is fixedly installed with a connecting plate 8, the top of the connecting plate 8 is fixedly installed with a scale rod 9, and the top end of the scale rod 9 extends to the outside through the sliding hole;

[0019] When too much liquid medicine enters the tank body 1, the scale rod 9 can be moved downward, and the connecting ring 7 can be moved to the scale line position of the required liquid medicine by comparing with the scale on the observation window 2, and then the excess medicine can be extracted by the pump body 4 and enter the liquid return tank 3.

[0020] A fixed tube 10 is fixedly installed on the top of the tank body 1, and a stirring motor 11 is fixedly installed on the top of the fixed tube 10. A rotating column 12 is fixedly installed on the bottom end of the rotating shaft of the stirring motor 11. A sliding cavity 13 is provided in the rotating column 12, and a through hole 14 is provided on the bottom wall of the sliding cavity 13. A slide plate 15 is slidably installed on the inner side wall of the sliding cavity 13, and a rotating rod 16 is fixedly installed on the bottom of the slide plate 15. The bottom end of the rotating rod 16 extends into the tank body 1, and a stirring rod is integrally formed on the side wall of the rotating rod 16. A horizontal plate 19 is fixedly installed on the right end of the side wall of the rotating rod 16, and a sliding block 20 is installed on the right side of the bottom of the horizontal plate 19. Vertical rods 18 are installed on the left and right ends of the fixing ring 17, and the top of the vertical rod 18 is fixedly installed on the inner top wall of the tank body 1, and the top of the fixing ring 17 is provided with an inclined surface, and the bottom of the sliding block 20 is slidably installed on the inclined surface.

[0021] When the rotating rod 16 rotates, it drives the slider 20 to slide in a circle on the inclined surface and move up and down, thereby causing the stirring rod to rotate and stir up and down, so as to facilitate mixing and stirring the medicine between the upper and lower stirring rods.

[0022] Specifically, the hose 6 is a corrugated tube.

[0023] Specifically, the slider 20 includes a wheel seat 21, which is fixedly installed on the bottom right side of the cross plate 19. A roller 22 is connected to the wheel seat 21 through a rotating shaft. An annular groove 23 is provided on the inclined surface, and the bottom end of the roller 22 is rollingly installed in the annular groove 23.

[0024] If a slider slides directly on the inclined surface, the sliding friction will be large and the service life of the parts will be reduced. By rolling the bottom end of the roller 22 in the annular groove 23, rolling can replace sliding, greatly reducing friction and increasing service life.

[0025] Specifically, the sliding cavity 13 is a square cavity, and the sliding plate 15 is a square plate that matches the sliding cavity 13 .

[0026] By arranging the sliding cavity 13 and the sliding plate 15 in a square shape, it is convenient for the rotating column 12 to drive the rotating rod 16 to rotate at the same time.

[0027] Specifically, a spring 24 is fixedly mounted on the top of the slide plate 15 , and the top end of the spring 24 is fixedly mounted on the top wall of the slide cavity 13 .

[0028] The spring 24 in the figure is in a compressed state. After the slide plate 15 moves upward, the slide plate 15, the rotating rod 16 and the stirring device can move downward by the rebound effect of the spring 24, thereby achieving a reset effect.

[0029] Specifically, the rotating column 12 includes a column 25 and a ring 26. Screws are installed at both ends of the bottom of the column 25. Mounting holes are provided on both sides of the bottom of the ring 26. Nuts are screwed through the bottom ends of the screws through the mounting holes.

[0030] By dividing the rotating column 12 into the column 25 and the ring 26 , it is convenient to open the sliding cavity 13 in the early stage, and it is also convenient to install the sliding plate 15 in the sliding cavity 13 .

[0031] Working principle: liquid medicine is injected through the feed pipe on the left side of the top of the tank body. When too much liquid medicine enters the tank body 1, the scale rod 9 can be moved downward, and the connecting ring 7 can be moved to the scale line position of the required liquid medicine by comparing with the scale on the observation window 2, and then the excess medicine is extracted into the return liquid tank 3 through the pump body 4, and then a certain amount of solid medicine is injected from the feed pipe. The stirring motor 11 drives the rotating 12 to rotate. When the rotating rod 16 rotates, it will drive the slider 20 to slide in a circle on the inclined surface and move up and down, so that the stirring rod rotates and stirs up and down, which is convenient for mixing and stirring the medicine between the upper and lower stirring rods.
