Description

Technical Field

[0001] The invention relates to the field of fin tube feeding equipment, in particular to an automatic feeding device and an automatic feeding method for fin tube milling gears. Background Art

[0002] Finned tubes are a kind of heat exchange element widely used in heat exchangers. Their main function is to enhance heat transfer efficiency and reduce flow resistance. The production process of finned tubes requires milling. The traditional finned tube feeding mechanism adopts a push design, that is, the finned tubes are transported to the front end of the push mechanism following the conveyor chain, and then the push mechanism pushes the finned tubes to the next station. This method will cause damage to the finned tubes because the finned tubes still generate a lot of friction with the conveyor chain during the pushing process.

[0003] For example, the Chinese patent with the publication number CN113732192B discloses an automatic loading and unloading device for finned tubes, which is composed of a tube pressing mechanism, a conveying and forming mechanism and a feeding mechanism. The tube pressing mechanism includes a material rack body, an upper pressing mechanism and a sequentially arranged tube body, and the upper pressing mechanism is composed of a micro cylinder, a pressing rod and a discharge fine-tuning structure; the conveying and forming mechanism includes a supporting structure, a conveying rack, an upper pressing roller, a lower supporting roller, a guide rod and a wire rope feeding mechanism, and the wire rope feeding mechanism includes a servo motor, a wire rope, an electromagnetic clutch and a driving wheel. The guide rod drives the tube body to perform an axial reciprocating motion, and the feeding mechanism includes a worm gear reduction motor, a first bearing seat and a material trough. The entire upper pressing mechanism is stable, can discharge and feed in an orderly manner, and can divide the tubes into separate zones. The upper pressing mechanism has a simple structure, a light weight, and will not shake. It remains stable under the clamping of the rubber wheel and the bearing, and the tube will not deform, making it more convenient to return the material. However, the above-mentioned automatic loading and unloading device for finned tubes does not lift or lower the tubes during loading and unloading, which may easily cause damage to the tubes.

[0004] In view of this, it is necessary to provide an automatic feeding device and an automatic feeding method for fin tube milling teeth. Summary of the invention

[0005] The invention provides an automatic feeding device and method for fin tube milling, which effectively solves the problem that the existing fin tube feeding method easily causes damage to the fin tube.

[0012] Furthermore, the driven wheel includes a shaft No. 1 fixedly arranged on the lifting seat and two ball bearings whose inner rings are fixedly connected to the shaft No. 1, and the two ball bearings are arranged at intervals.

[0013] Furthermore, the material discharging limiting mechanism includes a mounting frame arranged on one side of the frame, a baffle plate arranged on the mounting frame, and a material guide bin, and the material guide bin is provided with a funnel-shaped material discharging port.

[0014] Furthermore, the discharge port is higher than the end of the fin tube in the chain conveying mechanism.

[0015] Furthermore, the chain conveying mechanism includes a conveying chain, a plurality of jigs arranged on the conveying chain, a transmission shaft arranged at one end of a frame, a driven shaft arranged at the other end of the frame, a plurality of driving sprockets coaxially fixed on the driven shaft, a plurality of driven sprockets coaxially fixed on the driven shaft, and a No. 2 motor arranged on the frame for driving the transmission shaft to rotate, and the driven sprocket is connected to the driving sprocket through a conveying chain transmission.

[0019] 2. The lifting mechanism adopts a driven wheel assembly with no power at the bottom and a driving wheel assembly with power at the top, which can effectively reduce the friction of the lower end surface of the fin tube during the transportation process of the lifting mechanism and prevent the fin tube from being damaged.

[0030] In actual use, the finned tube is extended along the X direction and then arranged in the Y direction in the chain conveying mechanism 2. When it is conveyed to the corresponding position of the lifting and feeding mechanism 4 through the chain conveying mechanism 2, the finned tube is located between the driving wheel 421 and the driven wheel 433, and the finned tube does not contact the driving wheel 421.

[0042] In actual use, one end of the fin tube close to the discharge limiting mechanism 3 is limited by the baffle 31 before being conveyed to the guide bin 32. After being conveyed to the guide bin 32, it passes through the lifting and feeding mechanism 4 and is conveyed to the next station along the discharge port.
