Description

Technical Field

[0001] The utility model relates to the technical field of liquid filling, and in particular to an automatic liquid filling machine. Background Art

[0002] Filling machines are mainly a small category of packaging machines. From the perspective of material packaging, they can be divided into liquid filling machines, paste filling machines, powder filling machines, and granule filling machines. In terms of the degree of production automation, they can be divided into semi-automatic filling machines and fully automatic filling production lines.

[0003] After further searching, it was found that the authorization announcement number CN210286716U disclosed an automatic liquid filling machine, which, through a specific technical structure setting, effectively solved the technical disadvantages that when filling liquid, due to the characteristics of the liquid, the liquid is prone to splashing when entering the bottle body from the filling head. At the same time, if the bottle body is relatively light, it will also cause the bottle body to shake, resulting in poor filling quality.

[0004] However, the above-mentioned prior art still has many defects in actual use. For example, after the liquid is filled, a small amount of liquid will still adhere to the inner wall of the filling port. The small amount of residual liquid will drip downward from the inside of the filling port due to the influence of gravity. The dripping liquid will spill around the filling machine and cause pollution to the environment around the filling machine. Therefore, a function is needed to receive the liquid dripping from the filling head. Utility Model Content

Detailed Embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0021] As shown in Figures 1-4 , the present utility model provides a technical solution: a liquid automatic filling machine, including a support base 1. At the top of the support base 1, there is a liquid storage tank 2 for storing liquid. On one side of the top of the support base 1 near the liquid storage tank 2, a suction pump 3 is fixedly installed. The output end of the suction pump 3 is connected through a pipeline to one side of the outer wall of the liquid storage tank 2. The output end of the suction pump 3 is fixedly connected with a hose 4. The liquid to be filled is stored in the liquid storage tank 2. By starting the controller 10 to control the suction pump 3 to be powered on and operate, it is convenient for the suction pump 3 to suck the liquid stored inside the liquid storage tank 2 into the inside of the hose 4. On the side of the top of the support base 1 away from the liquid storage tank 2, there is a filling assembly for filling liquid. The filling assembly includes a lifting mechanism 5 and a filling port 6. The lifting mechanism 5 includes several groups of support frames 501. At the top of several groups of support frames 501, a top plate 502 is fixedly installed. At the bottom end of the top plate 502, a lead screw 503 is rotatably installed. At the top end of the top plate 502, a servo motor 505 is fixedly installed. The output end of the servo motor 505 is fixedly connected with the lead screw 503 through a shaft rod. A nut seat 504 is threadedly sleeved on the surface of the lead screw 503. And the side of the nut seat 504 away from the lead screw 503 is sleeved on the outside of the support frame 501. One end of the nut seat 504 close to the support frame 501 is fixedly installed with a filling port 6 through a mounting plate. The output end of the filling port 6 is fixedly connected with a control valve 601. The input end of the control valve 601 is fixedly connected with the output end of the hose 4. The operator controls the servo motor 505 to be powered on and operate through the controller 10 to drive the lead screw 503 to rotate forward. The forward-rotating lead screw 503 drives the nut seat 504 to move downward on the outside of the support frame 501. The downward-moving nut seat 504 drives the filling port 6 to move downward into the inside of the filling bottle through the mounting plate. Then the operator controls the control valve 601 to open through the controller 10, so as to convey the liquid inside the hose 4 through the opened control valve 601 from the filling port 6 to the inside of the filling bottle for filling, realizing the function of automatically filling the liquid.

[0022] As an implementation manner in this embodiment, as shown in Figure 1 and Figure 4As shown in the figure, a receiving mechanism 7 for receiving dripping liquid is provided at the bottom end of the support base 1. The receiving mechanism 7 includes a sliding rod 701 and a sliding seat 702. The sliding rod 701 is fixedly installed on both sides of the bottom end of the support base 1 through a mounting plate. Sliding seats 702 are slidably sleeved on the surfaces of the two groups of sliding rods 701. A connecting plate 704 is fixedly installed between the two groups of sliding seats 702. One end of the connecting plate 704 is fixedly installed with a receiving plate 705. A diversion groove 706 is formed on the surface of the receiving plate 705. The end of the connecting plate 704 away from the receiving plate 705 is fixedly connected with an electric telescopic rod 703, and the electric telescopic rod 703 is fixedly installed at the bottom end of the support base 1 through a ferrule. When the electric telescopic rod 703 is energized and operates, it drives the connecting plate 704 to move parallel. The parallel moving connecting plate 704 slides on the outside of the sliding rod 701 through the sliding seat 702, which facilitates the connecting plate 704 to move smoothly and parallel inside the sliding rod 701. The parallel moving connecting plate 704 drives the receiving plate 705 to move parallel below the filling port 6, facilitating the receiving plate 705 to receive the liquid dripping from the filling port 6.

[0023] As an implementation manner in this embodiment, as Figure 1 and Figure 4 shown, a placement table 9 for placing the filling bottle is fixedly installed on the lower side of the support base 1 close to the receiving mechanism 7. The operator places the filling bottle above the placement table 9. A collection box 8 for collecting dripping liquid is provided on the lower side of the support base 1 close to the receiving mechanism 7. Roller wheels 801 are installed on both sides of the bottom end of the collection box 8 through shaft brackets. The diversion groove 706 diverts the received liquid into the interior of the collection box 8, thereby facilitating the collection box 8 to collect the dripping liquid. The roller wheels 801 facilitate the movement of the collection box 8 on the ground. A controller 10 is fixedly installed on the side end of the support base 1 close to the lifting mechanism 5. The controller 10 is electrically connected to the suction pump 3, the servo motor 505, the control valve 601, and the electric telescopic rod 703 through wires, facilitating the operator to control the energized operation of the device through the controller 10.

[0024] Working principle: The liquid to be filled is stored in the liquid storage tank 2. First, the operator places the filling bottle above the placement table 9. Then, the operator controls the suction pump 3 to be energized and operate through the controller 10 to suck the liquid stored in the liquid storage tank 2 into the interior of the hose 4. At the same time, the operator controls the servo motor 505 to be energized and operate through the controller 10 to drive the lead screw 503 to rotate forward. The forward rotating lead screw 503 drives the lead screw sleeve seat 504 to move downward on the outside of the support frame 501. The downward moving lead screw sleeve seat 504 drives the filling port 6 to move downward into the filling bottle through the mounting plate. Then, the operator controls the control valve 601 to open through the controller 10, facilitating the liquid in the hose 4 to be transported from the opened control valve 601 to the interior of the filling bottle through the filling port 6 for filling, realizing the automatic filling function of the liquid.

[0025] When the filling bottle is filled with liquid, the reverse rotation of the wire sleeve seat 504 drives the filling port 6 to move upward through the wire sleeve seat 504 and the mounting plate to disengage from the inside of the filling bottle. At the same time, the operator controls the electric telescopic rod 703 to energize and operate through the controller 10 to drive the connecting plate 704 to move parallel. The parallel moving connecting plate 704 slides on the outside of the slide bar 701 through the slide block 702, so that the connecting plate 704 can move smoothly in parallel inside the slide bar 701. The parallel moving connecting plate 704 drives the receiving plate 705 to move parallel to the lower part of the filling port 6, facilitating the receiving plate 705 to receive the liquid dripping from the filling port 6. The received liquid flows into the inside of the collection box 8 through the diversion groove 706, thus facilitating the collection box 8 to collect the dripping liquid, realizing the function of receiving the liquid dripping from the filling port 6, avoiding the problem that the liquid dripping from the filling port 6 after filling pollutes the surrounding environment of the filling machine, and ensuring the cleanliness of the surrounding environment of the filling machine.

[0026] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
