Description

Technical Field

[0001] This utility model relates to the field of aluminum processing technology, specifically to an online conveying device for a grain refiner in aluminum casting with dual wires. Background Technology

[0002] Solid-state batteries represent the future of lithium-ion batteries, while pouch cells represent a definitive packaging technology for them. As the application of solid-state batteries expands in electric vehicles, consumer electronics, and energy storage, the demand for pouch aluminum-plastic films will continue to increase. Currently, aluminum foil for battery pouch aluminum-plastic films is produced using 8021 alloy, and the manufacturing process typically includes the following key steps: casting, hot rolling, cold rolling, recrystallization annealing, cold rolling, foil rolling, slitting, and finished product annealing. During the casting stage, to effectively control the solidification structure of the aluminum ingot and refine the grains, specific grain refiners need to be added to the molten aluminum. Currently, the industry commonly uses Al5Ti1B and Al5Ti0.2B wires as grain refiners, which are continuously fed into the molten aluminum flow channel through simultaneous addition of two wires.

[0003] The core problem with existing methods of conveying grain refiners is that current technologies mainly employ the following structure: a reel (feed-off wheel) wound with grain refiner filaments is mounted on a rotating shaft, and one end of the filament is led out and passes through the roller gap formed by an active drive roller and a driven pressure roller (passive roller). By driving the active roller to rotate, the friction between the roller and the filament pulls the filament forward, achieving continuous conveying. However, this method has the following problem: during the forward movement of the filament pulled by the active roller, the reel (feed-off wheel) lacks effective braking or damping control, causing it to rotate freely under inertia, and there is no guiding mechanism to guide the filament. This uncontrolled free rotation makes the filament prone to excessive detachment from the reel, and the detached filament is easily entangled or stuck on other parts of the device (e.g., the edge or corner of the equipment base plate), ultimately leading to interruption of filament conveying and severely affecting the grain refinement effect. Utility Model Content

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] Please see Figure 1-4 This utility model provides a technical solution: an online conveying device for an aluminum casting double-wire grain refiner, including a base plate 1, two wire feeding wheels 21 installed on one side of the base plate 1, a guide wheel assembly installed in the middle of the base plate 1, and a conveying roller assembly installed on the other side of the base plate 1. The guide wheel assembly includes a mounting frame 4 mounted on the base plate 1. The mounting frame 4 has two symmetrically arranged guide wheels 41 and two guide shafts 42 rotatably arranged on it, with the two guide shafts 42 located between the two guide wheels 41. One guide wheel 41 and one guide shaft 42 form a guide member, which can guide the wire. The conveying roller assembly includes a base 5 mounted on the base plate 1. An active roller 6 with two annular grooves is rotatably arranged on the base 5. A passive roller 9 with adjustable downward pressure is installed on the base 5. The passive roller 9 has an annular groove corresponding to the annular groove. The rotation of the active roller 6 and the passive roller 9 extends and retracts the wire. The annular grooves and annular grooves are used to engage the wire and increase the friction between the active roller 6 and the passive roller 9 and the wire.

[0020] Furthermore, the upper surface of the base plate 1 corresponding to the wire feeding wheel 21 is provided with a fixed shaft 2. The wire feeding wheel 21 is rotatably sleeved on the fixed shaft 2, and the upper part of the fixed shaft 2 is threaded. The upper part of the fixed shaft 2 is threaded with a nut 22. The resistance can be applied to the wire feeding wheel 21 by rotating the nut 22 to prevent the wire feeding wheel 21 from rotating excessively under inertia and causing the wire to fall off.

[0021] Furthermore, a fixing seat 3 is installed on the base plate 1 at the position between the wire feeding wheel 21 and the guide wheel assembly. Two parallel guide rollers 31 are rotatably mounted on the fixing seat 3 to keep the wire material entering the guide member between the two guide rollers 31.

[0022] Furthermore, a servo motor 51 for driving the active roller 6 to rotate is provided on one side of the base 5.

[0023] Furthermore, a screw 7 is installed on the base 5, and a horizontal plate 8 is movably sleeved on the screw 7. The passive roller 9 is rotatably mounted on the horizontal plate 8. A spring 71 is sleeved on the side of the upper part of the screw 7 on the horizontal plate 8, and a tension nut 72 is threadedly connected to the upper side of the screw 7 to limit the spring 71. In the initial state, the passive roller 9 can only be in contact with the top of the active roller 6 under the action of gravity. In order to ensure that the active roller 6 and the passive roller 9 can pull and transport the filament, the tension nut 72 is rotated. The tension nut 72 presses down on the horizontal plate 8 through the spring 71. The horizontal plate 8 drives the passive roller 9 to move down, thereby increasing the squeezing force of the active roller 6 and the passive roller 9 on the filament and ensuring that the filament can be pulled.

[0024] The servo motor 51 used in this utility model is a commonly used electrical device in the prior art. Its working method and circuit structure are well known technologies and will not be described in detail here.

[0025] When using:

[0026] The finer agent filament feed roller 21 is fitted onto the fixed shaft 2, and then the nut 22 is rotated to tighten the feed roller 21 so that it can rotate under stress.

[0027] The finer agent filaments are passed sequentially between two guide rollers 31, between guide wheel 41 and guide shaft 42, and between drive roller 6 and passive roller 9;

[0028] The servo motor 51 is controlled to work, and the servo motor 51 controls the rotation of the active roller 6. The active roller 6 drives the passive roller 9 to rotate through the finer agent filaments. During this process, the finer agent filaments are conveyed.

[0029] This invention can prevent the wire feeding wheel 21 from rotating freely under inertia, and can also guide the wire, preventing the wire from falling off and preventing the wire from getting stuck or tangled on other parts. It can stably transport the wire, thereby ensuring the grain refinement effect and is easy to use.

Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
