Description

Technical Field

[0001] This utility model relates to the field of processing and manufacturing, and in particular to a dust removal device for a cold rolling mill. Background Technology

[0002] In existing technologies, aluminum foil requires oil spraying during cold rolling to form a layer of oil on the surface, facilitating cooling and reducing friction. However, impurities such as aluminum shavings and dust adhere to the aluminum foil surface during rolling, easily causing scratches and white streaks. Uneven oil distribution can also lead to grease spots in subsequent processes. Related technologies suffer from ineffective dust removal devices, failing to distribute the oil evenly across the aluminum foil surface. Furthermore, the airflow angle is not adjustable, resulting in a fixed contact surface between the aluminum foil and the airflow from the dust removal device, which cannot be adapted to specific needs.

[0003] Therefore, it is necessary to provide a dust removal device for cold rolling mills to overcome the defects mentioned above. Utility Model Content

[0004] The purpose of this utility model is to provide a dust removal device for a cold rolling mill. By designing the dust removal device, the angle of the dust removal device can be adjusted to achieve a better dust removal effect. At the same time, multiple air outlets are set to increase the contact area of ​​the blowing air.

[0005] According to one aspect of this utility model, a dust removal device for a cold rolling mill is provided, comprising an air supply duct, a dust removal component, and a limit adjustment component. The air supply duct is fixed on the cold rolling mill for supplying air, and the dust removal component is connected to the air supply duct to blow air out. The dust removal component is fixed to the side of the cold rolling mill near the aluminum foil plate. The limit adjustment component is used to adjust the angle of the dust removal component with respect to the vertical direction. The dust removal component is used to supply air to the aluminum foil plate. The dust removal component includes a first dust removal component placed above the aluminum foil plate and a second dust removal component placed below the aluminum foil plate. Both the first and second dust removal components have two air nozzles. The first dust removal component, placed above the aluminum foil plate, includes an upper air inlet duct, a first upper connecting duct, a second upper connecting duct, a first lower air outlet duct, and a second lower air outlet duct. The first and second air nozzles are connected by an upper air inlet duct that is horizontally positioned and passes through a limit adjustment assembly. The upper air inlet duct is connected to the air supply duct. A first upper connecting pipe is connected to one end of the upper air inlet duct and is bent. A second upper connecting pipe is connected to the other end of the upper air inlet duct and is bent. A first lower air outlet duct is connected to the lower end of the first upper connecting pipe. A second lower air outlet duct is parallel to the first lower air outlet duct and is connected to the lower end of the second upper connecting pipe. A first air nozzle is connected to the lower end of the first lower air outlet duct to blow air onto the aluminum foil plate. A second air nozzle is connected to the lower end of the second lower air outlet duct to blow air onto the aluminum foil plate. A second dust removal assembly is placed below the aluminum foil plate and includes a third and a fourth air nozzle.

[0006] The above solution allows the angle of the dust removal device to be adjusted to change the airflow direction, thereby regulating the airflow angle and ensuring greater airflow on the aluminum foil surface for better dust removal. At the same time, the multiple nozzles increase the contact area of ​​the dust removal air, making the lubricating oil on the aluminum foil surface more evenly dispersed. This prevents the oil from accumulating on the aluminum plate surface, which could lead to problems such as grease spots on the aluminum foil in subsequent processes, thus ensuring the quality of the aluminum foil.

[0007] Preferably, the first dust removal component is placed above the aluminum foil plate and the angle with the vertical direction is less than 60 degrees, and the second dust removal component has the same structure as the first dust removal component, is placed below the aluminum foil plate and the angle with the vertical direction is less than 60 degrees.

[0008] Preferably, the angle α between the first lower air outlet duct and the vertical direction is greater than 15 degrees and less than 60 degrees.

[0009] Preferably, the second dust removal assembly further includes a lower air inlet pipe, a first lower connecting pipe, a second lower connecting pipe, a first upper air outlet pipe, a second upper air outlet pipe, a third air nozzle, and a fourth air nozzle. The lower air inlet pipe is arranged horizontally and passes through the limiting adjustment assembly, and is connected to the air supply pipe. The first lower connecting pipe is connected to one end of the lower air inlet pipe and is bent. The second lower connecting pipe is connected to the other end of the lower air inlet pipe, and is bent. The first upper air outlet pipe is connected to the upper end of the first lower connecting pipe. The second upper air outlet pipe is arranged parallel to the first upper air outlet pipe and is connected to the upper end of the second lower connecting pipe. The third air nozzle is connected to the upper end of the first lower air outlet pipe and is used to blow air to the aluminum foil plate. The fourth air nozzle is connected to the upper end of the second lower air outlet pipe and is used to blow air to the aluminum foil plate.

[0010] Preferably, the limit adjustment assembly includes a limit part and an adjustment bolt. The limit part is sleeved on the dust removal assembly and fixedly connected to the cold rolling mill. The adjustment bolt can be used to adjust the angle between the dust removal assembly and the vertical direction.

[0011] Preferably, the adjusting bolt passes through the limiting part in the front-to-back direction and abuts against the dust removal component. Loosening the adjusting bolt is used to adjust the angle between the dust removal component and the vertical direction. After adjusting the angle between the dust removal component and the vertical direction, tightening the adjusting bolt is used to fix it.

[0012] Preferably, the first air nozzle, the second air nozzle, the third air nozzle, and the fourth air nozzle have the same structure.

[0013] Preferably, the first air nozzle includes a first air guide plate disposed inside and a second air guide plate disposed on both sides of the first air guide plate. The second air guide plate is bent and includes at least four second air guide plates.

The dust removal component is connected to the air supply duct to blow out air. The dust removal component is fixed to the front end of the cold rolling mill. The limit adjustment component is used to adjust the angle between the dust removal component and the vertical direction, so that the angle of the dust removal device can be adjusted to adjust the air outlet direction and thus adjust the air outlet angle to achieve a better dust removal effect. At the same time, it increases the contact area of ​​the dust removal air, so that the lubricating oil on the surface of the aluminum foil is more evenly dispersed, preventing the oil from accumulating on the surface of the aluminum plate and causing problems such as grease spots on the aluminum foil in subsequent processes, thus ensuring the quality of the aluminum foil.
