Therefore, the position of the liquid outlet pipe needs to be adjusted so that the liquid outlet pipe corresponds to the opening of the filling bottle. However, for the existing filling machine, manual adjustment one by one is required, which not only has low debugging efficiency, but also cannot guarantee the accuracy. At the same time, since the injection is made of chemical agents, other foreign substances will remain in the liquid medicine. If it is filled in the medicine bottle, defective products will be produced. Summary of the Utility Model

[0021] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text only describes one or several specific implementation manners of the present utility model, and does not strictly limit the specific protection scope claimed by the present utility model.
[0022] Please refer to Figures 1 - 3As shown in the figure, an injection filling machine includes a conveying mechanism 1, a column 2, a lifting cylinder 3 and an equalizing mechanism 4. The conveying mechanism 1 includes two side plates 12 and legs 11 at its bottom. A conveying plate 13 is installed between the two side plates 12. By driving the motor, a plurality of mutually articulated conveying plates 13 move, thereby realizing the movement of the medicine bottles. Empty bottles are placed on the surface of the conveying plate 13. A column 2 is vertically arranged at the rear of the conveying mechanism 1. A lifting cylinder 3 is arranged at the top of the column 2. The equalizing mechanism 4 is suspended above the conveying mechanism 1. The equalizing mechanism 4 includes a lifting plate 41. An extension plate 42 is arranged at the rear of the lifting plate 41. The extension plate 42 slides on the surface of the column 2. The output end of the lifting cylinder 3 is fixed between the lifting plate 41 and the extension plate 42. By controlling the lifting cylinder 3, the lifting plate 41 can be moved in the vertical direction. A track groove 43 is transversely opened on the surface of the lifting plate 41. I-shaped sliders 44 are evenly slidably installed inside the track groove 43. Linking rods 48 are installed on the upper surfaces of adjacent two I-shaped sliders 44 through pins to realize the linkage of a plurality of I-shaped sliders 44 and ensure that the distance between adjacent two I-shaped sliders 44 is consistent. A liquid discharging mechanism 5 is installed at the bottom of the I-shaped slider 44. The liquid discharging mechanism 5 corresponds to the position of the filling bottle. The liquid discharging mechanism 5 includes a filling cylinder 51 fixed at the bottom of the I-shaped slider 44. The back of the filling cylinder 51 is connected to an infusion hose to convey liquid medicine into the filling cylinder 51. A lower sealing cover 52 is installed at the bottom of the filling cylinder 51 through bolts. A liquid discharging pipe 53 is arranged at the bottom of the lower sealing cover 52. The size of the liquid discharging pipe 53 is smaller than the open mouth of the filling bottle, so that the liquid discharging pipe 53 can enter the medicine bottle during filling to realize accurate filling.
[0023] Among them, a double threaded rod 45 is installed inside the track groove 43 through bearings. The two outermost I-shaped sliders 44 are screwed on different threaded surfaces of the double threaded rod 45. Through holes are opened on the surfaces of the remaining I-shaped sliders 44. The double threaded rod 45 passes through a plurality of through holes. By rotating the double threaded rod 45, the two outermost I-shaped sliders 44 are synchronously controlled to move, but the double threaded rod 45 does not directly act on other I-shaped sliders 44. The double threaded rod 45 passes through one side surface of the lifting plate 41. A knob 47 is arranged at the end of the double threaded rod 45 to facilitate the external control of the double threaded rod 45
[0024] Please refer to Figure 4 As shown in the figure, a filter screen 54 is arranged inside the lower sealing cover 52 to filter the liquid medicine during filling and prevent foreign objects from entering the medicine bottle.
[0025] Among them, the bottom of the liquid outlet pipe 53 is conical, and a buffer sheet 56 is slidably installed on the surface of the liquid outlet pipe 53. The size of the buffer sheet 56 is larger than the opening of the filling bottle. During filling, the buffer sheet 56 is placed on the opening of the filling bottle to seal the opening to prevent splashing during filling. A spring 55 is sleeved on the surface of the liquid outlet pipe 53. The bottom of the spring 55 is fixed on the surface of the buffer sheet 56, and the top of the spring 55 is connected to the lower surface of the lower sealing cover 52. The elastic force of the spring 55 is used to buffer the buffer sheet 56 to prevent collision with the filling bottle.
[0026] Please refer to Figure 1 As shown, fixed cylinders 14 are evenly arranged above the side plates 12, and sliding bolts 16 are horizontally slidably installed inside the fixed cylinders 14. Limiting plates 15 are arranged at the ends of multiple sliding bolts 16 on the same side. Two limiting plates 15 are suspended above the conveying plate 13, and the filling bottles are placed between the two limiting plates 15. A locking bolt 17 is screwed on the top of the fixed cylinder 14. By adjusting the limiting plates 15 on both sides and using filling bottles of different sizes, the stability of the filling bottles when moving is guaranteed.
[0027] The working principle of the utility model is as follows: first, the positions of the two limiting plates 15 are adjusted according to the size of the filling bottle, so that the gap between the two limiting plates 15 is just enough for the filling bottle to pass through, and then multiple bottles are placed on the surface of the side plate 12, and the conveying work of multiple empty bottles is realized through the side plate 12. Similarly, the distance between the multiple liquid discharge mechanisms 5 at the top is adjusted according to the size of the filling bottle. Since the liquid discharge mechanism 5 is installed on the surface of the I-shaped slider 44, the distance of the liquid discharge mechanism 5 can be controlled by controlling the distance of the I-shaped slider 44. The rotating knob 47 can drive the double-threaded rod 45 to rotate, and then control the two I-shaped sliders 44 at the end to approach or move away at the same time. The rotation of the double-threaded rod 45 will not directly affect the other I-shaped sliders 44, but when the two I-shaped sliders 44 at the end are close to or away from each other, they can be equally divided through the connecting rod 48 connected to each other at the top, ensuring that the distance between the two adjacent I-shaped sliders 44 is consistent, thereby ensuring accuracy during filling. The equal division mechanism 4 can be controlled to move up and down by the lifting cylinder 3, and then the up and down movement of multiple liquid discharge mechanisms 5 can be controlled. During filling, the liquid discharge mechanism 5 is controlled to move downward, so that the liquid discharge pipe 53 enters the interior of the filling bottle, and the buffer sheet 56 covers the bottle mouth to prevent splashing. The liquid medicine will be filtered by the filter screen 54 during filling to prevent foreign matter from being poured into the bottle.
[0028] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
