Description

Technical Field

[0001] This utility model relates to the field of aluminum tube processing technology, specifically to an automatic feeding device for an aluminum tube annealing furnace. Background Technology

[0002] Annealing of aluminum parts utilizes changes in the metal's crystal structure and microstructure to alter the properties of the aluminum parts by controlling the heating and cooling processes. When an aluminum part is heated to a certain temperature, its crystal structure changes, releasing internal stress and thus improving its plasticity and toughness.

[0003] After the aluminum tubes are heated in the annealing furnace, they need to be removed from the furnace. Since the aluminum tubes still have a certain temperature, a conveyor system of a certain length is needed to transport them during removal. This conveying process helps to lower the temperature of the aluminum tubes. The annealing furnace conveyor system transports the aluminum tubes to the unloading device for unloading. Patent publication number CN116873288A discloses an automatic unloading platform, specifically disclosing that several conveying rollers are rotatably connected to the frame, and an unloading mechanism is also provided on the frame. The unloading direction of the unloading mechanism is not the same as the conveying direction of the conveying rollers. A transfer mechanism is also provided between the conveying rollers and the unloading mechanism. The transfer mechanism transfers the workpieces from the conveying rollers to the unloading mechanism for unloading. However, because the spacing between the aluminum tubes in the front row and the next row on the annealing furnace conveyor system is small, and the aluminum tubes in each row are not evenly arranged in the longitudinal direction, ... Figure 1 As shown, if the above-mentioned automatic feeding platform is used, there are problems such as unstable feeding, low feeding efficiency, and complex feeding device structure.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0015] Please see Figure 2-7 This utility model provides a technical solution: an automatic feeding device for an aluminum tube annealing furnace, including a driven roller 2 and a driving roller 3 mounted on a feeding support 1. The right side of the feeding support 1 is rotatably equipped with multiple driven rollers 2 for longitudinally conveying aluminum tubes 300, and the left side of the feeding support 1 is rotatably equipped with multiple driving rollers 300 for longitudinally conveying aluminum tubes 300. A horizontally arranged limiting baffle 9 is fixedly mounted on the left end of the feeding support 1. The feeding support 1 is equipped with a driving mechanism 7 for driving the driving rollers 3 to rotate. The drive mechanism 7 includes a drive motor 71 and multiple longitudinally arranged transmission shafts 72. The transmission shafts 72 are rotatably connected to the rear side wall of the unloading bracket 1 through bearing seats, and the transmission shafts 72 are fixedly connected to each other through a coupling 73. The drive motor 71 is fixedly connected to the transmission shaft 72 on the left side through the coupling 73. Worm teeth 721 are provided on the transmission shafts 72 at the positions corresponding to the active rollers 3.

The drive mechanism 7 can drive the active rollers 3 to quickly convey the aluminum tubes 300 longitudinally. The feeding support 1 is provided with no less than two transversely arranged transverse conveyors 4. The transverse conveyors 4 are connected to the feeding support 1 through a lifting mechanism 5. In this embodiment, the transverse conveyors 4 are belt conveyors and the lifting mechanism 5 is a worm gear lift. The conveying end of the transverse conveyor 4 is fixedly provided with a receiving hopper 8. The right end of the unloading bracket 1 is provided with an upper support mechanism 6. The upper support mechanism 6 includes an auxiliary bracket 61 fixed to the right end of the unloading bracket 1.

A roller 64 is rotatably connected to the lifting frame 63. A proximity switch 10 is provided at the position of the rightmost active roller 3 on the unloading bracket 1.

[0016] In this embodiment, the distance between the rightmost drive roller 3 and the support roller 64 is greater than half the axial length of the aluminum tube 300; In use: The aluminum tube 300 is conveyed towards the material feeding device via the annealing furnace conveyor 200. After passing the idler roller 64, the aluminum tube 300 moves onto the driven roller 2. When the proximity switch 10 detects the aluminum tube 300, the drive motor 71 drives the transmission shaft 72 to rotate. The worm gear 721 on the transmission shaft 72 meshes with the worm wheel 31 connected to the drive roller 3, and all the drive rollers 3 rotate synchronously to perform longitudinal conveying of the aluminum tube 300. At this time, at least half of the aluminum tube 300 is conveyed. The aluminum tube 300 is moved to the unloading device. The lifting mechanism 62 extends to push the lifting frame 63 and the roller 64 to rise. The roller 64 lifts the aluminum tube 300 so that its rear part is tilted upward and separated from the annealing furnace conveyor 200. The aluminum tube 300 on the unloading device is quickly conveyed to the limit baffle 9 by the drive roller 3. Then, the horizontal conveyor 4 is pushed up by the lifting mechanism 5 to lift the aluminum tube 300. The lifted aluminum tube 300 is then horizontally conveyed into the receiving hopper 8 by the horizontal conveyor 4, completing the automatic unloading. After the aluminum tubes 300 in the previous row are finished being unloaded, the lifting mechanism 2 62 drives the roller 64 to descend and return to its original state, and the lifting mechanism 1 5 drives the transverse conveyor 4 to descend and return to its original state, and continues to unload the aluminum tubes 300 in the next row.

[0017] Furthermore, the bottom of the transverse conveyor 4 is provided with a connecting frame 41, and a slider 42 is provided on the connecting frame 41. The unloading bracket 1 is vertically provided with a slide rail 43, and the slider 42 is slidably connected to the slide rail 43, thereby improving the stability of the transverse conveyor 4 when it is raised or lowered.

[0018] Furthermore, the lifting frame 63 is provided with a second slider 65, and the auxiliary support 61 is provided with a second slide rail 66 vertically, and the second slider 65 is slidably connected to the second slide rail 66, thereby improving the stability of the lifting frame 63 and the roller 64 during lifting.

[0019] The automatic feeding device for aluminum tube annealing furnace disclosed in this embodiment lifts the aluminum tube 300 by the upper support mechanism 6, causing its rear section to tilt upwards and detach from the annealing furnace conveying device 200; the drive mechanism 7 drives the active roller 3 to rotate, quickly conveying the aluminum tube 300 on the feeding device to the limiting baffle 9, thereby quickly separating the aluminum tubes 300 in the front row from the aluminum tubes 300 in the back row; then the lifting mechanism 5 pushes the transverse conveyor 4 to rise, lifting the aluminum tube 300, and the transverse conveyor 4 then transversely conveys the lifted aluminum tube 300 into the receiving hopper 8, completing the automatic feeding; the aluminum tube 300 feeding is stable, the feeding efficiency is high, the feeding device has a simple structure, and the cost is low.
