An automatic feeding component 7 is fixedly mounted on the side of the stirring motor 3 away from the control switch 6 and on the top of the top cover 2. During use, the interaction of the furnace 1, top cover 2, stirring motor 3, rotating rod 4, stirring rod 5, control switch 6, and automatic feeding component 7 enables the automatic addition of grain refiner during the use of the copper alloy tube production grain refinement device, improving work safety and thus facilitating better practicality.

[0020] The automatic feeding assembly 7 includes a material cylinder 8, which is fixedly installed inside the top cover 2. The top of the material cylinder 8 extends above the top of the top cover 2. A positioning frame 9 is fixedly installed on the outside of the material cylinder 8. A support frame 10 is fixedly installed on the top of the end of the positioning frame 9 away from the material cylinder 8. An adjusting motor 11 is fixedly installed on the top of the outer side of the support frame 10. An adjusting shaft 12 is rotatably installed on the top of the inner side of the support frame 10. The output shaft of the adjusting motor 11 movably passes through one side of the support frame 10 and is fixedly connected to one end of the adjusting shaft 12. An adjusting gear 13 is fixedly installed inside the support frame 10 and outside the adjusting shaft 12. A movable rack 14 is meshed with the outer side of the adjusting gear 13. A movable frame 15 is fixedly installed on the side of the rack 14 away from the adjusting gear 13. A movable rod 16 is fixedly installed at the bottom of the movable frame 15 away from the movable rack 14. A circular plate 17 is fixedly installed at the bottom of the movable rod 16, and the circular plate 17 is located at the top of the material cylinder 8. A feed pipe 20 is fixedly installed through the top of the circular plate 17. An end cap 21 is threaded on the outer side of the top of the feed pipe 20. The diameter of the circular plate 17 is adapted to the inner diameter of the material cylinder 8. A connecting rod 18 is fixedly installed in the middle of the bottom end of the circular plate 17. A conical stop 19 is fixedly installed at the bottom of the connecting rod 18, and the bottom diameter of the conical stop 19 is adapted to the inner diameter of the material cylinder 8. The conical stop 19 is located at the bottom of the inside of the material cylinder 8.

[0021] A positioning sleeve 22 is fixedly installed inside the movable frame 15 on the side away from the movable rack 14. A positioning rod 23 is slidably installed inside the positioning sleeve 22, and the bottom of the positioning rod 23 is fixedly connected to the top of the positioning frame 9. A limit block 24 is fixedly installed on the top of the positioning rod 23. Positioning sliders 25 are symmetrically fixedly installed on the inner wall of the positioning sleeve 22. Positioning grooves 26 are symmetrically opened on the outer side of the positioning rod 23, and the positioning sliders 25 are slidably installed inside the positioning grooves 26. Through the interaction of the positioning sleeve 22, positioning rod 23, limit block 24, positioning slider 25 and positioning groove 26, the movable frame 15 can achieve better stability when moving, thereby ensuring that the automatic feeding component 7 can work stably.

[0022] Working principle: During operation, the required amount of grain refiner is first weighed. The weighing is calculated using the following formula: Refiner mass = Melt mass × (Target element percentage / Element content in refiner) × Yield. Then, the end cap 21 at the top of the feed pipe 20 is unscrewed, and the weighed grain refiner is added to the inside of the barrel 8 through the feed pipe 20. The end cap 21 is then tightened again. At this point, the required grain refiner is located between the conical baffle 19 and the circular plate 17 inside the barrel 8. The furnace 1 then heats and melts the material. When the melt temperature reaches 1150~1200℃, the regulating motor 11 is started, driving the regulating shaft 12 to rotate. The regulating shaft 12 drives the regulating gear 13 to rotate, which in turn drives the movable rack 14 to move downwards. The movable rack 14 drives the movable frame 15 to move downwards, and the movable frame 15 drives the positioning sleeve 22 to slide outside the positioning slide rod 23. The positioning slider 25 slides inside the positioning groove 26, ensuring better stability of the movable frame 15 during movement. Simultaneously, the movable frame 15 moves the movable rod 16 downwards, which in turn moves the circular plate 17 downwards. The circular plate 17, through the connecting rod 18, pushes the conical stop 19 downwards. The downward movement of the conical stop 19 removes the obstruction of the bottom of the material cylinder 8. Then, the grain refiner inside the material cylinder 8 is pushed down into the furnace 1 along with the downward movement of the circular plate 17. At the same time, the stirring motor 3 drives the rotating rod 4 to rotate, which in turn drives the stirring rod 5 to move. The stirring rod 5 agitates the melt, ensuring the grain refiner is fully mixed within the melt. The copper alloy tube is then poured within 30 minutes after the grain refiner takes effect. This allows the grain refiner device for copper alloy tube production to automatically add grain refiner during use, improving operational safety and enhancing practicality.
