However, when the gel injector is removed from the filling equipment after filling, the piston handle of the gel injector may fall to the ground first, causing the gel inside the gel injector to spray out and resulting in waste.

[0021] 1. In this utility model, when the rotating shaft rotates, it drives the first comb gear to rotate, which in turn drives the third gear to rotate, so that the third gear rotates in the same direction as the first comb gear. This causes the second rotating shaft to drive the lever to rotate, which in turn pushes the empty cylinder out through the guide plate. The piston handle is blocked by the stop bar, ensuring that the empty cylinder falls onto the inclined plate first when it is pushed out, thus preventing the piston handle from falling first and avoiding the gel inside the empty cylinder from being sprayed out.

When the empty cylinder rotates to the injection needle, the cylinder lowers the small empty can, allowing the injection needle to be inserted into the empty cylinder. The suction device draws the gel from the storage tank and inputs it into the small empty can. The air pump pressurizes the inside of the small empty can, so that the gel inside the small empty can is injected into the cylinder through the injection needle, thereby ensuring that the amount of gel injected from the empty cylinder is the same each time.

The outer side of the protective shell 1 is fixedly connected to an inclined plate 18, which is used to make the empty cylinder 22 fall onto the inclined plate 18 first.
[0034] Reference Figure 1 , Figure 2 and Figure 6 The protective shell 1 has an annular groove 19 on the top of its inner wall. A turntable 20 is fixedly connected to the outside of the rotating shaft 3. Multiple slots 21 are provided on the outside of the turntable 20. An empty cylinder 22 is provided on the inner wall of the annular groove 19 and the slots 21. A piston handle 23 is slidably connected to one end of the empty cylinder 22 for transporting the empty cylinder 22. A platform 24 is provided on the outside of the protective shell 1. A storage tank 25 is fixedly connected to the top of the platform 24. An empty tube 26 is fixedly connected to the outside of the storage tank 25. A suction device 27 is fixedly connected to one end of the empty tube 26. An empty tube 28 is fixedly connected to the external output end of the suction device 27. The bottom of the suction device 27 is fixedly connected to the top of the platform 24 for extracting gel from the storage tank 25.
[0035] Reference Figure 1 and Figure 2 Platform 24 is externally fixedly connected to a support plate 29. A cylinder 30 is fixedly connected to the top of the support plate 29. A connecting rod 31 is fixedly connected to the outside of the cylinder 30. A small empty can 32 is fixedly connected to the outside of the connecting rod 31 to ensure that the amount of gel injected each time is the same. An injection needle 33 is fixedly connected to the bottom of the small empty can 32. The small empty can 32 is externally fixedly connected to one end of an empty tube 28 for inserting into the empty cylinder 22 to inject the gel. Platform 24 is toply fixedly connected to an air pump 35. An air suction tube is fixedly connected to the input end of the air pump 35. An air tube 34 is fixedly connected to the output end of the air pump 35. An injection head 36 is fixedly connected to one end of the air tube 34. The injection head 36 is detachably connected to the top of the small empty can 32 for pressurizing the small empty can 32.
[0036] Working principle: First, the empty cylinder 22 enters the slot 21 through the through-slot in the protective shell 1 via the guide plate 16. The motor 2 is started to drive the rotating shaft 3 to rotate, thereby driving the turntable 20 to rotate. When the turntable 20 rotates, it drives the empty cylinder 22 to rotate through the slot 21. The annular groove 19 and the slot 21 ensure that the empty cylinder 22 can move smoothly. When the empty cylinder 22 moves below the injection needle 33, the suction device 27 is started, and the gel inside the storage tank 25 is extracted through the first empty tube 26. A certain amount of gel is sent into the small empty tank 32 through the second empty tube 28 to ensure that the small empty tank 32 is full.
[0037] Subsequently, the starting cylinder 30 drives the connecting rod 31 to descend, thereby causing the small empty can 32 and the injection needle 33 to descend. At the same time, the injection needle 33 is inserted into the empty cylinder 22 until it reaches its deepest point. The air pump 35 is started, and gas is drawn in through the suction tube and delivered through the air tube 34. The gas enters the small empty can 32 through the injection head 36, pressurizing the inside of the small empty can 32. This allows the gel inside the small empty can 32 to be injected into the small empty can 32 through the injection needle 33. When the gel injection is complete, the cylinder 30 drives the small empty can 32 to rise and return to its original position.
[0038] When the empty cylinder 22 is full, the rotating shaft 3 continues to drive the turntable 20 to rotate, and the empty cylinder 22 moves to the through slot near the receiving block 15. When the rotating shaft 3 rotates, it will drive the comb gear 4 to rotate. The comb gear 4 will drive the gear 7 to rotate through meshing, so that the gear 7 will drive the gear 9 to rotate through meshing, so that the rotation direction of the gear 9 and the comb gear 4 are consistent. When the gear 9 rotates, it will drive the lever 10 to rotate. When the lever 10 rotates, it will touch the empty cylinder 22. The lever 10 will move the empty cylinder 22 towards the inclined plate 18, so that it moves along the guide plate 16. When the piston handle 23 touches the stop lever 17, the stop lever 17 will apply a force to the piston handle 23 that should be opposite to the direction of movement of the empty cylinder 22, and the empty cylinder 22 will continue to move forward. When the empty cylinder 22 leaves the guide plate 16, it will fall downwards, and the piston handle 23 will fall upwards onto the inclined plate 18, sliding down by gravity.
[0039] When lever 10 moves, it will squeeze damper 11 and damper 2 12, causing them to deform. When comb gear 1 4 no longer meshes with gear 2 7, gear 3 9 loses the force exerted on it by gear 2 7. At this time, lever 10 loses the force exerted on damper 11 and damper 2 12, and damper 11 and damper 2 12 begin to rebound, pushing lever 10 back to its original position, and repeating this process.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
