[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-3 , a filling line emergency stop reflux device, comprising a support frame 1, a support plate 2 is slidably connected to the top of the support frame 1, two slide grooves are provided on the top of the support frame 1, the bottoms of the two ends of the support plate 2 are respectively located inside the two slide grooves, and two support plates 2 are provided, the two support plates 2 are respectively located on both sides of the support frame 1, the two support plates 2 are symmetrically distributed about the central axis plane of the support frame 1, the tops of the two support plates 2 are fixedly connected with electric hydraulic rods 3, the two electric hydraulic rods 3 are respectively connected to an external power supply, the telescopic ends of the two electric hydraulic rods 3 are fixedly connected with a mounting frame 4, the bottom of the mounting frame 4 is fixedly connected with a reserved pipe 5, the outer side wall of the reserved pipe 5 is fixedly connected with a liquid inlet pipe 7, the bottom of the reserved pipe 5 is fixedly connected with a delivery pipe 6, the bottom of the reserved pipe 5 is fixedly connected with a reset spring 8, the reset spring 8 is located outside the delivery pipe 6, the end of the reset spring 8 away from the reserved pipe 5 is fixedly connected with a shunt pipe 9, the inner side wall of the shunt pipe 9 is connected to the outer side of the delivery pipe 6 The side walls are slidably connected, one end of the delivery pipe 6 close to the shunt pipe 9 is located inside the shunt pipe 9, and the center point of the delivery pipe 6 coincides with the center point of the shunt pipe 9. The outer wall of the shunt pipe 9 is fixedly connected with a liquid outlet pipe 10, and the inner wall of the shunt pipe 9 is fixedly connected with a partition frame 11. The top and bottom of the partition frame 11 are both provided with through holes. The outer wall of the shunt pipe 9 is adapted to the inner wall of the through hole at the top of the partition frame 11. The inner bottom of the shunt pipe 9 is fixedly connected with a column 12. The column There are four 12, the four columns 12 are distributed in a circular array at the inner bottom of the shunt tube 9, and the outer side walls of the four columns 12 are slidably connected with plugs 13, the plugs 13 are in a quarter-cylindrical shape, the tops of the four plugs 13 are all provided with an inclined angle, and the tops of the four plugs 13 are all provided with a convex block, the bottoms of the four plugs 13 are all fixedly connected with springs 14, and the ends of the four springs 14 away from the four plugs 13 are respectively fixedly connected to the inner bottom of the shunt tube 9;

[0023] When in use, the electric hydraulic rod 3 is started, and the electric hydraulic rod 3 drives the mounting frame 4 to move toward the bottle body or the tank body. When the bottom of the shunt tube 9 conflicts with the top of the tank body, as the mounting frame 4 continues to move, the reserved tube 5 will continue to be pushed toward the tank body. Because the bottom of the shunt tube 9 conflicts with the top of the tank body, when the reserved tube 5 moves toward the tank body, the top of the shunt tube 9 will squeeze the return spring 8, so that the delivery tube 6 enters the inside of the shunt tube 9 and continues to move toward the tank body. When the bottom of the delivery tube 6 conflicts with the top bump of the plug 13, as the delivery tube 6 moves, the delivery tube 6 conflicts with the plug 13 to squeeze the spring 14, and finally the delivery tube 6 passes through the inside of the partition frame 11 and squeezes the plug 13 out of the inside of the partition frame 11. At this time, the filling equipment is started, and the material is poured from the delivery tube 6 into the inside of the shunt tube 9 and further poured into the tank body.

[0024] When the tank body or bottle body is tilted, or the shunt tube 9 is not aligned with the tank body, the shunt tube 9 cannot interfere with the tank body, so that the delivery tube 6 cannot pass through the partition frame 11. At this time, the through hole set at the bottom of the partition frame 11 is blocked by the plug 13 to prevent the material from flowing out. During filling, the material will enter the interior of the partition frame 11 and be guided along the liquid outlet pipe 10 to the liquid storage tank.

[0025] Reference Figure 1 and Figure 4 The outer wall of the support frame 1 is fixedly connected with a motor 16, which is connected to an external power supply. Two motors 16 are provided, and the two motors 16 are symmetrically distributed on the central axis plane of the support frame 1. The output ends of the two motors 16 are fixedly connected with threaded rods 17, and the outer walls of the two threaded rods 17 are threadedly connected with the outer walls of the two support plates 2. When the position of the filling equipment needs to be adjusted, the two motors 16 are started, and the two motors 16 drive the two threaded rods 17 to rotate, thereby moving the positions of the two support plates 2.

[0026] Reference Figure 2 and Figure 3 The bottom of the shunt pipe 9 is fixedly connected with a filling head 15, which is located at the bottom center of the shunt pipe 9. When the opening of the can or bottle is small, the filling head 15 can be inserted into the inside of the can or bottle to avoid spilling of materials during filling.

[0027] Reference Figure 1 and Figure 4 A conveyor belt 18 is provided on the top of the support frame 1. The conveyor belt 18 is connected to an external power supply. The conveyor belt 18 is located below the filling equipment and at the top center of the support frame 1. After the conveyor belt 18 is started, the can body and the bottle body on the top of the conveyor belt 18 are driven by the conveyor belt 18 to move, thereby facilitating the filling of new bottles.

[0028] Reference Figure 1 and Figure 4 The outer wall of the support frame 1 is fixedly connected with a mounting plate 19, and two mounting plates 19 are provided. The two mounting plates 19 are respectively located on both sides of the conveyor belt 18. When in use, the mounting plates 19 limit the positions of the two ends of the conveyor belt 18 to avoid changes in the angles of the two ends of the conveyor belt 18 as the conveyor belt 18 continues to run during use, thereby avoiding changes in the positions of the bottles and cans on the top of the conveyor belt 18 and avoiding inaccurate filling.

[0029] Reference Figure 1 and Figure 4 The tops of the two mounting plates 19 are respectively fixedly connected with guardrails 20, and the bottoms of the two guardrails 20 are both provided with arcs. The two guardrails 20 are respectively located above the conveyor belt 18. When in use, the guardrails 20 resist the outer wall of the bottle body to prevent the bottle body from falling during the filling process.

[0030] Working principle: When in use, start the electric hydraulic rod 3, and the electric hydraulic rod 3 drives the mounting frame 4 to move toward the bottle body or the tank body. When the bottom of the shunt tube 9 conflicts with the top of the tank body, as the mounting frame 4 continues to move, the reserved tube 5 will continue to be pushed toward the tank body. Because the bottom of the shunt tube 9 conflicts with the top of the tank body, when the reserved tube 5 moves toward the tank body, the top of the shunt tube 9 will squeeze the return spring 8, so that the delivery tube 6 enters the inside of the shunt tube 9 and continues to move toward the tank body. When the bottom of the delivery tube 6 conflicts with the top bump of the plug 13, as the delivery tube 6 moves, the delivery tube 6 conflicts with the plug 13 to squeeze the spring 14, and finally the delivery tube 6 passes through the inside of the partition frame 11 and squeezes the plug 13 out of the inside of the partition frame 11. At this time, the filling equipment is started, and the material is poured from the delivery tube 6 into the inside of the shunt tube 9, and further poured into the tank body;

[0031] When the tank body or bottle body is tilted, or the shunt tube 9 is not aligned with the tank body, the shunt tube 9 cannot interfere with the tank body, so that the delivery tube 6 cannot pass through the partition frame 11. At this time, the through hole set at the bottom of the partition frame 11 is blocked by the plug 13 to prevent the material from flowing out. During filling, the material will enter the interior of the partition frame 11 and be guided along the liquid outlet pipe 10 to the liquid storage tank.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
