[0020] The following will further describe the present application in detail Figures 1-3 with reference to the accompanying drawings.

[0021] The embodiments of the present application disclose an anti - coagulation filling nozzle structure. Refer to Figures 1-3 , which includes a filling pipe 1 installed on the tank body. A valve 11 is installed on the filling pipe 1. An anti - coagulation mechanism is arranged beside the filling pipe 1. The anti - coagulation mechanism includes a lifting cylinder 2, a slide rail 3, a carriage 4, a rotary cylinder 5, a connecting frame 6 and a sealing plate 7. The lifting cylinder 2 and the slide rail 3 are both vertically fixed on the filling pipe 1. The carriage 4 is slidably installed on the slide rail 3. The rotary cylinder 5 is vertically fixed on the carriage 4. The connecting frame 6 is fixed on the piston rod of the rotary cylinder 5. The sealing plate 7 is detachably installed on the connecting frame 6. A connecting hole is opened in the middle of the sealing plate 7. A screw 61 is fixed on the connecting frame 6. The sealing plate 7 is installed on the screw 61 through the connecting hole and fixed by a nut. A sealing gasket is arranged between the sealing plate 7 and the connecting frame 6;

[0022] The bottom of the filling pipe 1 has an annular block 8. The cross - section of the annular block 8 is trapezoidal, and the width of the lower surface of the annular block 8 is greater than the width of the upper surface of the annular block 8. The width of the upper surface of the annular block 8 is the same as the thickness of the filling pipe 1. An annular groove 81 is opened at the bottom of the annular block 8. The sealing plate 7 can be clamped into the annular groove 81;

[0023] An air extraction hole is opened on the side wall of the filling pipe 1. The air extraction hole is arranged between the annular block 8 and the valve 11. An air extraction nozzle 9 is installed on the air extraction hole. In order to prevent glue from entering the air extraction nozzle 9, the air extraction nozzle 9 extends into the interior of the filling pipe 1.

[0024] Refer to Figure 3 , at the position corresponding to the annular groove 81 on the periphery of the sealing plate 7, there is an annular protrusion 71, and a lower sealing gasket is fixed on the surface of the annular protrusion 71. An upper sealing gasket is fixed in the annular groove 81. In order to facilitate the annular protrusion 71 on the sealing plate 7 to slide into the annular groove 81, a chamfer is provided at the edge of the annular groove 81.

[0025] Refer to Figure 2 , at the inner edge of the annular block 8, there is a glue - dripping ring block 10 extending downward. The setting of the glue - dripping ring block 10 can provide a guiding function for the glue, prevent liquid from entering the annular groove 81, thereby reducing the generation of glue coagulation substances, and preventing the coagulation substances from falling into the filled bottle and affecting the product quality.

[0026] The implementation principle of an anti - coagulation filling nozzle structure in the embodiments of the present application is as follows:

[0027] After the work is finished and the machine stops, the rotary cylinder 5 drives the connecting frame 6 to rotate. The connecting frame 6 drives the sealing plate 7 to move to directly below the filling pipe 1. The lifting cylinder 2 pulls the carriage 4 upward. The carriage 4 drives the sealing plate 7 to move. The annular protrusion 71 on the sealing plate 7 abuts tightly in the annular groove 81, which can seal the bottom of the filling pipe 1. After that, the filling pipe 1 is evacuated through the air extraction nozzle 9, and the air between the valve 11 and the sealing plate 7 can be pumped away to form a vacuum, thus avoiding the polyaddition reaction and curing of the glue adhering to the inner wall of the filling pipe 1 catalyzed by trace water in the air.

[0028] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
