[0004] The aluminum foil flattening machine in the aforementioned patent relies mainly on the tension of the winding to straighten the aluminum foil during the flattening process, and then passes the aluminum foil between the flattening rollers, which makes the aluminum foil prone to damage during the flattening, conveying and winding process. Utility Model Content

[0005] The purpose of this invention is to provide an aluminum foil roller flattening device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an aluminum foil roller flattening device, including a frame, a roller flattening assembly is provided on one side of the frame, and an elastic auxiliary roller assembly is provided on the other side of the frame. The elastic auxiliary roller assembly includes a support frame, and swing arms are rotatably connected on both sides of the inner wall of the support frame. An auxiliary frame is rotatably connected at one end of the swing arm near the roller flattening assembly. The auxiliary frame is rotatably connected to the swing arm through a rotating shaft. A torsion spring is provided between the rotating shaft and the swing arm. An auxiliary roller is rotatably connected between the two auxiliary frames.

[0007] Furthermore, the end of the swing arm away from the auxiliary frame is rotatably connected to the output end of the cylinder, and the other end of the cylinder is rotatably connected to the inner wall of the support frame.

[0008] Furthermore, the cylinder is located below the swing arm, and the support frame is fixedly connected to the bottom of the inner wall of the frame.

[0009] Furthermore, the auxiliary frame has a Y-shaped structure, with auxiliary rollers rotatably connected to both ends of the top of the auxiliary frame, and the bottom center of the auxiliary frame is rotatably connected to the swing arm via a rotating shaft.

[0010] Furthermore, the roller flattening assembly includes a support roller that is rotatably connected and a flattening roller that is movably connected.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0013] 1. This utility model, by setting up an elastic auxiliary roller assembly, a swing arm, an auxiliary frame, a rotating shaft, and an auxiliary roller, allows for the conveying, flattening, and winding of aluminum foil. As the aluminum foil is conveyed forward under the traction force of winding, the surface of the auxiliary roller is in close contact with the surface of the aluminum foil, providing rolling support. The force on the surface of the aluminum foil is transmitted to the surface of the auxiliary roller, and the force on the surface of the auxiliary roller is transmitted to the auxiliary frame. A torsion spring provides elastic torsional support between the rotating shaft and the swing arm, allowing the auxiliary frame to elastically torsionally reset after being subjected to force. This achieves elastic adaptive support and adaptive adjustment of the auxiliary roller, ensuring that the aluminum foil is in an adaptively straightened state after being processed by the elastic auxiliary roller assembly. It can adaptively adjust according to the magnitude of the tension on the aluminum foil, keeping the aluminum foil in a straightened state at all times. This allows the aluminum foil to enter the roller flattening assembly more smoothly for flattening. The auxiliary roller can swing around the rotating shaft and also around the rotation axis of the swing arm, effectively increasing the adjustment range of the auxiliary roller and allowing it to adapt to a wider range of aluminum foil tension. This further improves the safety and stability of the aluminum foil during the flattening process.

[0014] 2. In this utility model, the roller flattening assembly is used to flatten the aluminum foil, and the elastic auxiliary roller assembly is used to provide elastic rolling assistance to the aluminum foil before it enters the roller flattening assembly. This effectively provides elastic rolling support to the aluminum foil during the flattening, conveying, and winding processes, ensuring that the aluminum foil remains straight and does not break or become damaged due to excessive tension. The support frame provides rotational support to the swing arm, the swing arm supports the auxiliary frame, the rotating shaft provides rotational support to the auxiliary frame, and the torsion spring provides elastic torsional support to the auxiliary frame. The auxiliary frame can swing as a whole with the swing arm, and simultaneously, the auxiliary frame can elastically torsionally swing along the rotating shaft, allowing the auxiliary roller to swing as a whole with the swing arm and elastically torsionally swing around the rotating shaft.

[0021] 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.

[0022] Please see Figures 1-4This utility model provides a technical solution: an aluminum foil roller flattening device, comprising a frame 1, a roller flattening assembly 2 disposed on one side of the frame 1, and an elastic auxiliary roller assembly 3 disposed on the other side of the frame 1. The elastic auxiliary roller assembly 3 includes a support frame 301, and swing arms 302 rotatably connected to both sides of the inner wall of the support frame 301. An auxiliary frame 303 rotatably connected to one end of each swing arm 302 near the roller flattening assembly 2 is provided, and the auxiliary frame 303 is rotatably connected to the swing arm 302 via a rotating shaft 304. A torsion spring is provided between the rotating shaft 304 and the swing arm 302, and an auxiliary roller 305 is rotatably connected between the two auxiliary frames 303; one end of the swing arm 302 away from the auxiliary frame 303 is rotatably connected to the output end of the cylinder 306, and the other end of the cylinder 306 is rotatably connected to the inner wall of the support frame 301; the auxiliary frame 303 has a Y-shaped structure, and the top two ends of the auxiliary frame 303 are respectively rotatably connected to the auxiliary roller 305, and the bottom center of the auxiliary frame 303 is rotatably connected to the swing arm 302 through the rotating shaft 304.

[0023] In one embodiment, the cylinder 306 is located below the swing arm 302, so that the cylinder 306 will not obstruct the auxiliary roller 305 during the extension and retraction movement, which can effectively avoid damage to the aluminum foil; the support frame 301 is fixedly connected to the bottom of the inner wall of the frame 1, and sets the position of the elastic auxiliary roller assembly 3 to ensure that the elastic auxiliary roller assembly 3 rolls and guides the aluminum foil in the middle of the roller flattening assembly 2, so that the aluminum foil can enter the roller flattening assembly 2 more smoothly for flattening operation.

[0024] In one embodiment, the roller flattening assembly 2 includes a rotatably connected support roller 201 and a movably connected flattening roller 202. The flattening roller 202 has rotatably connected bearing seats 203 fitted at both ends. A guide frame 204 is vertically provided inside the frame 1. The bearing seats 203 are slidably connected to the guide frame 204. During the flattening process, the aluminum foil passes between the support roller 201 and the flattening roller 202 of the roller flattening assembly 2. The rotatable cooperation of the support roller 201 and the flattening roller 202 effectively flattens the aluminum foil. The bearing seats 203 provide rotatable support positions at both ends of the flattening roller 202, and the guide frame 204 provides vertical sliding guide support positions for the bearing seats 203, effectively ensuring the stability of the lifting and lowering adjustment of the bearing seats 203, thereby ensuring the safety and stability of the lifting and lowering movement of the flattening roller 202.

[0025] In one embodiment, the top of the bearing seat 203 is provided with a slider 205 that is slidably connected to the guide frame 204. A hydraulic cylinder 206 is vertically provided on the top of the slider 205. The hydraulic cylinder 206 is fixedly connected to the frame 1. The slider 205 provides sliding support on the top of the bearing seat 203. The extension and retraction of the hydraulic cylinder 206 can drive the slider 205 to move up and down, thereby driving the bearing seat 203 to move up and down, and thus driving the flattening roller 202 to move up and down. This allows for adjustment of the distance between the support roller 201 and the flattening roller 202, facilitating the adjustment of the pressure on the aluminum foil surface. The operation is convenient and quick.

[0026] The working principle of this utility model:

[0027] Refer to the instruction manual appendix Figures 1-4 This invention comprises a roller flattening assembly 2, an elastic auxiliary roller assembly 3, a swing arm 302, an auxiliary frame 303, a rotating shaft 304, and an auxiliary roller 305. The frame 1 supports the roller flattening assembly 2 and the elastic auxiliary roller assembly 3. The roller flattening assembly 2 is used to flatten the aluminum foil, and the elastic auxiliary roller assembly 3 is used to provide elastic rolling assistance to the aluminum foil before it enters the roller flattening assembly 2. This effectively provides elastic rolling support to the aluminum foil during the flattening, conveying, and winding processes, ensuring that the aluminum foil remains straight at all times. The aluminum foil will not break or be damaged due to excessive tension; the support frame 301 provides rotational support for the swing arm 302, the swing arm 302 supports the auxiliary frame 303, the rotating shaft 304 provides rotational support for the auxiliary frame 303, and the torsion spring provides elastic torsional support for the auxiliary frame 303. The auxiliary frame 303 can swing as a whole with the swing arm 302, and at the same time, the auxiliary frame 303 can elastically torsionally swing along the rotating shaft 304, so that the auxiliary roller 305 can swing as a whole with the swing arm 302, and at the same time, it can elastically torsionally swing around the rotating shaft 304.

[0028] When the elastic auxiliary roller assembly 3 is working, the auxiliary roller 305 supports the aluminum foil at the top of the auxiliary frame 303. During the conveying, flattening, and winding of the aluminum foil, the auxiliary roller 305 provides rolling support at the bottom of the aluminum foil. As the aluminum foil is conveyed forward under the traction force of winding, the surface of the auxiliary roller 305 is in close contact with the surface of the aluminum foil, providing rolling support. The force on the surface of the aluminum foil is transmitted to the surface of the auxiliary roller 305, and the force on the surface of the auxiliary roller 305 is transmitted to the auxiliary frame 303. The auxiliary frame 303 rotates along the rotating shaft 304 under the force. The torsion spring provides elastic torsional support between the rotating shaft 304 and the swing arm 302, allowing the auxiliary frame 303 to elastically torsionally reset after being subjected to force, thereby achieving elastic adaptive support and adaptive adjustment of the auxiliary roller 305. The aluminum foil is in an adaptive straightening state after being processed by the elastic auxiliary roller assembly 3. It can adaptively adjust according to the magnitude of the tension on the aluminum foil, and the aluminum foil is always in the straightening device, so that the aluminum foil can enter the roller flattening assembly 2 for flattening more smoothly. The rotation of the swing arm 302 can drive the auxiliary frame 303 located at one end of the swing arm 302 to swing, so that the auxiliary roller 305 can swing around the rotation axis of the swing arm 302. The auxiliary roller 305 can swing around the rotation axis 304 and the rotation axis of the swing arm 302 at the same time, which can effectively improve the adjustment range of the auxiliary roller 305, so that the auxiliary roller 305 can adapt to a wider range of aluminum foil tension, and further improve the safety and stability of the aluminum foil in the flattening process.

[0029] The cylinder 306 can extend and retract, causing one end of the swing arm 302 to swing, which in turn causes the auxiliary frame 303 on the other end of the swing arm 302 to swing in the opposite direction. This supports the swing of the swing arm 302, ensuring its safety and stability, and consequently, the stability and safety of the auxiliary frame 303. The air pressure of the cylinder 306 can be set to a fixed value, so that the support of the cylinder 306 on one end of the swing arm 302 is under a fixed air pressure. After the auxiliary roller 305 is subjected to force, the air pressure of the cylinder 306 remains unchanged. Depending on the magnitude of the force on the auxiliary roller 305, the pressure transmitted to the swing arm 302 will vary, and the force transmitted to the swing arm 302 will be transmitted to the cylinder 306. The extension and retraction length of the cylinder 306 can be adaptively adjusted, thus ensuring that the swing arm 302 can be adaptively adjusted.

[0030] The auxiliary frame 303 is designed as a Y-shaped structure, and auxiliary rollers 305 are rotatably connected at the top of the Y-shaped structure of the auxiliary frame 303. The cooperation of the two auxiliary rollers 305 can effectively improve the rolling support surface of the auxiliary rollers 305 on the auxiliary frame 303 for the aluminum foil, and at the same time expand the rolling support range of the aluminum foil, which can further improve the rolling support effect of the aluminum foil and improve the safety and stability of the aluminum foil in the flattening, conveying and winding process.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
