[0023] Further, a controller 4 is provided below the mounting plate 5, and the liquid level sensor 10, the electric telescopic rod 8, and the electric valve are all electrically connected to the controller 4.
[0024] Specifically, during operation, the controller 4 controls the electric telescopic rod 8 to drive the metering cylinder 11 to move. The controller 4 controls the electric valves on the liquid outlet pipe 24 and the feed pipe 9 to open, so that the water-based paint in the paint storage tank 6 enters the metering cylinder 11 through the liquid outlet pipe 24, the hose 7 and the feed pipe 9. When the water-based paint in the metering cylinder 11 reaches the liquid level sensor 10, the liquid level sensor 10 transmits a signal to the controller 4, and the controller 4 controls the electric valves on the liquid outlet pipe 24 and the feed pipe 9 to close, thereby realizing the control of the amount of water-based paint entering the metering cylinder 11, realizing the quantitative filling of water-based paint, and avoiding the waste of water-based paint.
[0025] In this embodiment, a discharge pipe 25 is provided on the metering cylinder 11, and an anti-drip mechanism is provided in the discharge pipe 25. The anti-drip mechanism includes a connecting plate 14, a sealing plate 21 fixedly arranged on the inner wall of the discharge pipe 25, and a top cover 22 slidably connected to the inner wall of the discharge pipe 25. A water-based paint transition cavity is formed between the connecting plate 14 and the sealing plate 21. A connecting rod 19 is provided on the top cover 22, a perforation is formed at the center of the sealing plate 21, the connecting rod 19 penetrates through the perforation, and a sealing cover 20 is provided on the connecting rod 19. The sealing cover 20 can move to the perforation along with the connecting rod 19 and seal the perforation. The sealing plate 21 is used to block the liquid so that the liquid will not flow out of the discharge pipe 25. Among them, the perforation on the sealing plate 21 is sealed by the sealing cover 20 so that the liquid will not flow out of the perforation.
[0026] Further, an elastic member is provided on the connecting plate 14. The elastic member includes a guide cylinder 16 arranged below the connecting plate 14. The guide cylinder 16 is located in the water-based paint transition cavity. A spring 17 is arranged in the guide cylinder 16. A guide plate 18 is provided on the connecting rod 19, and the upper part of the guide plate 18 is connected to the spring 17. The elastic member can drive the above-mentioned sealing cover 20 to move so that the sealing cover 20 moves to the perforation. When the spring 17 is in a natural state, the sealing cover 20 is at the perforation and can seal the perforation to prevent the water-based paint from flowing out.
[0027] Further, a plurality of first through holes 15 are evenly spaced on the connecting plate 14, and a plurality of second through holes 23 are evenly spaced on the top cover 22.
[0028] Specifically, the electric telescopic rod 8 drives the metering cylinder 11 to move up and down, so that the discharge pipe 25 on the metering cylinder 11 is docked with the mouth of the paint can 12. After the mouth of the paint can 12 enters the discharge pipe 25, it pushes up the top cover 22. The top cover 22 drives the connecting rod 19 to move. During the movement of the connecting rod 19, the elastic member deforms, storing elastic potential energy. At the same time, the sealing cover 20 on the connecting rod 19 moves out of the through hole on the sealing plate 21. At this time, the water-based paint in the metering cylinder 11 flows into the water-based paint transition cavity along the first through hole 15, and then the water-based paint flows along the second through hole 23 of the top cover 22, so as to fill the inside of the paint can 12 through the second through hole 23. When the paint can 12 is filled, the mouth of the can is removed from the discharge pipe 25. During the removal process, the elastic member recovers, converts the elastic potential energy into elastic force to push the connecting rod 19 to move back, and finally moves the sealing cover 20 on the connecting rod 19 to the through hole of the sealing plate 21 to complete the sealing of the through hole, ensuring that the water-based paint no longer flows out, thus avoiding the situation of residual water-based paint in the discharge pipe 25, and effectively preventing the residual water-based paint from dripping.
[0029] In this embodiment, a filling table 13 is further arranged on the base 1, and a placing groove 3 for placing the paint can 12 is arranged on the filling table 13.
[0030] Working principle of the utility model: First, place the paint can 12 in the placement groove 3 on the filling table 13, and then control the electric valves on the liquid outlet pipe 24 and the feed pipe 9 to open through the controller 4, so that the water-based paint in the paint storage tank 12 enters the metering cylinder 11 through the liquid outlet pipe 24, the hose 7 and the feed pipe 9. When the water-based paint in the metering cylinder 11 reaches the liquid level sensor 10, the liquid level sensor 10 transmits a signal to the controller 4, and the controller 4 controls the electric valves on the liquid outlet pipe 24 and the feed pipe 9 to close, thereby realizing the control of the amount of water-based paint entering the metering cylinder 11, realizing the quantitative filling of water-based paint, and avoiding the waste of water-based paint; after the metering cylinder 11 enters a fixed amount of water-based paint, the controller 4 controls the electric telescopic rod 8 to drive the metering cylinder 11 to move, so that the discharge pipe 25 on the metering cylinder 11 is docked with the can mouth of the paint can 12. After the can mouth of the paint can 12 enters the discharge pipe 25 on the metering cylinder 11, it lifts the top cover. The top cover 22 drives the connecting rod 19 to move. During the movement of the connecting rod 19, the elastic member deforms and stores elastic potential energy. At the same time, the sealing cover 20 on the connecting rod 19 moves out of the through hole on the sealing plate 21. At this time, the water-based paint in the metering cylinder 11 flows into the water-based paint transition cavity along the first through hole 15, and then the water-based paint flows along the second through hole 23 of the top cover 22, so as to carry out the filling work into the paint can 12 through the second through hole 23; when the paint can 12 is filled, move the can mouth out of the discharge pipe 25. During the removal process, the elastic member recovers, converts the elastic potential energy into elastic force to push the connecting rod 19 to move back, and finally makes the sealing cover 20 on the connecting rod 19 move to the through hole of the sealing plate 21 to complete the sealing of the through hole, ensuring that the water-based paint no longer flows out, thereby avoiding the situation that the discharge pipe 25 remains with water-based paint, and effectively preventing the residual water-based paint from dripping.
[0031] To sum up, the liquid level sensor 10 of the utility model detects the amount of water-based paint in the metering cylinder 11, and then controls the opening or closing of the electric valves on the liquid outlet pipe 24 and the feed pipe 9 through the controller 4, thereby realizing the control of the amount of water-based paint entering the metering cylinder 11, realizing the quantitative filling of water-based paint, and avoiding the waste of water-based paint; and through the compression and reset of the elastic member, the sealing cover 20 on the connecting rod 19 realizes the sealing and opening of the through hole of the sealing plate 21, thereby avoiding the situation that the discharge pipe 25 remains with water-based paint, effectively preventing the residual water-based paint from dripping, and avoiding the waste of resources.
[0032] On the premise of no conflict, those skilled in the art can freely combine and superimpose the above-mentioned additional technical features.
[0033] The above is only the preferred implementation mode of the utility model. As long as the technical solutions that achieve the purpose of the utility model by basically the same means are within the protection scope of the utility model.
