Description

Technical Field

[0001] This utility model relates to the field of aluminum foil technology, and specifically to an aluminum foil tension adjustment device. Background Technology

[0002] Due to its excellent properties, aluminum foil is widely used in food, beverages, cigarettes, pharmaceuticals, photographic plates, and household daily necessities. It is commonly used as packaging material, electrolytic capacitor material, insulation material for buildings, vehicles, ships, and houses. It can also be used as decorative gold and silver thread, wallpaper, and decorative trademarks for various stationery printed materials and light industrial products.

[0003] Currently, during the cold rolling process of aluminum foil, due to the thinness of the aluminum foil, the conventional tension adjustment mechanism involves the roller contacting the aluminum foil. When adjusting the tension, the roller applies pressure to the aluminum foil, and the force contact between the aluminum foil and the roller can lead to wear, breakage, or deformation of the aluminum foil. Utility Model Content

[0004] The purpose of this invention is to develop an aluminum foil tension adjustment device that adjusts the aluminum foil tension through airflow to avoid damage and deformation caused by the aluminum foil coming into forceful contact with the roller.

[0008] The second support is positioned opposite to the first support;

[0009] A rotating roller is rotatably positioned between the first support and the second support;

[0010] The rotating roller is a hollow cylindrical structure with a number of air holes evenly distributed on it. The first support is provided with an air inlet pipe that communicates with the inside of the rotating roller, and the second support is provided with a drive assembly that drives the rotating roller to rotate.

[0011] Optionally, the air holes are arranged radially along the roller, and the air holes are frustum-shaped with the larger end located inside the roller.

[0013] Optionally, the end of the roller that is rotatably connected to the first support is an open end.

[0014] Optionally, an air passage adjustment cover is provided on the first support inside the rotating roller. The air passage adjustment cover is arc-shaped and adapted to the inner wall of the rotating roller. The outer wall of the air passage adjustment cover is in sliding contact with the inner wall of the rotating roller.

[0015] Optionally, a barometer for monitoring air pressure is provided on the inner wall of the air path adjustment cover.

[0016] Optionally, the central angle covered by the air passage adjustment cover in the circumferential direction is 240°, and the opening of the air passage adjustment cover is directly above.

[0017] Optionally, the end of the roller that is rotatably connected to the second support is a closed end, and the driving assembly includes a motor mounted on the second support, the motor being drivenly connected to the closed end of the roller.

[0018] Optionally, the side of the roller is equipped with a laser Doppler velocimeter for monitoring the conveying speed of the aluminum foil.

[0019] The beneficial effects of this utility model are:

[0020] This invention delivers a constant-pressure airflow, which is ejected from a rotating roller, causing the aluminum foil to pass over the outside of the roller. The aluminum foil and the roller are in non-contact or only slightly contact, preventing damage or deformation of the aluminum foil. The airflow can also make uniform contact with the aluminum foil, ensuring that the aluminum foil is evenly stressed and avoiding deformation caused by excessive or insufficient stress in certain areas. The tension of the aluminum foil can be adjusted by changing the air pressure. The air path adjustment cover ensures that the airflow is directed only towards the aluminum foil delivery path, avoiding ineffective airflow and waste. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] like Figure 1 and Figure 2 As shown, this utility model discloses an aluminum foil tension adjustment device, including a first support 1 and a second support 2 arranged opposite to each other. The side walls of the first support 1 and the second support 2 are respectively provided with annular retaining rings 3 in a coaxial state. The first support 1 and the second support 2 are arranged vertically, and the retaining rings 3 are arranged horizontally along their axial direction.

[0030] A rotating roller 6 is rotatably provided between the first support 1 and the second support 2. The rotating roller 6 is a hollow cylindrical structure. The rotating roller 6 is rotatably located inside the retaining ring 3 of the first support 1 and the second support 2. The rotating roller 6 and the retaining ring 3 are coaxially rotatably connected. The outer diameter of the rotating roller 6 is adapted to the inner diameter of the retaining ring 3. The rotating roller 6 and the retaining ring 3 are rotatably sealed together.

[0031] The rotating roller 6 has an open end and a closed end. The open end of the rotating roller 6 is in rotatable contact with the first support 1, and the closed end of the rotating roller 6 is in rotatable contact with the second support 2. The rotating roller 6 between the two retaining rings 3 on the first support 1 and the second support 2 is covered with a number of air holes. The air holes are evenly arranged on the circumferential sidewall of the rotating roller 6, and the axial direction of the air holes is arranged radially along the rotating roller 6. The air holes are frustoconical in shape, with the larger end located inside the rotating roller 6.

[0032] The second support 2 is provided with a drive assembly for driving the rotating roller 6 to rotate. The drive assembly includes a motor 4 provided on the second support 2. The motor 4 is connected to the closed end of the rotating roller 6 for transmission. The operation of the motor 4 drives the closed end of the rotating roller 6 to rotate, thereby realizing the rotation of the rotating roller 6.

[0033] An air path adjustment cover 7 is provided on the first support 1 inside the rotating roller 6. The air path adjustment cover 7 can adjust the range of air jet of the rotating roller 6. The air path adjustment cover 7 is arc-shaped and adapted to the inner wall of the rotating roller 6. The outer diameter of the air path adjustment cover 7 is adapted to the inner diameter of the rotating roller 6. The outer wall of the air path adjustment cover 7 slides in contact with the inner wall of the rotating roller 6. The central angle covered by the air path adjustment cover 7 in the circumferential direction is 240°, that is, the air path adjustment cover 7 has an opening of 120°. The airflow inside the rotating roller 6 is ejected from the opening. In this embodiment, the aluminum foil passes over the rotating roller 6, so the opening is directly above, that is, the opening faces the aluminum foil conveying trajectory.

[0034] The first support 1 is equipped with an air inlet pipe 5 that communicates with the inside of the rotating roller 6 and the inside of the air path adjustment cover 7. A barometer for monitoring air pressure is installed on the inner wall of the air path adjustment cover 7. A laser Doppler velocimeter (not shown in the figure) for monitoring the aluminum foil conveying speed is installed on the side of the rotating roller 6. The linear velocity of the rotating roller 6 is matched with the aluminum foil conveying speed.

[0035] This invention delivers a constant-pressure airflow, which is ejected from the rotating roller 6, causing the aluminum foil to pass over the outside of the roller 6. The aluminum foil and the rotating roller 6 are in non-contact or only slightly contact, thus avoiding damage or deformation of the aluminum foil. The airflow can also make uniform contact with the aluminum foil, ensuring that the aluminum foil is evenly stressed and preventing deformation caused by excessive or insufficient stress in certain areas. The tension of the aluminum foil can be adjusted by changing the air pressure. The air path adjustment cover 7 ensures that the airflow is only output towards the aluminum foil delivery trajectory, avoiding ineffective airflow output and waste.

[0036] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the technical solutions of this utility model. Any technical solution that can be implemented based on the above embodiments without creative effort should be considered to fall within the scope of protection of this utility model patent.
