Description

Technical Field

[0001] This utility model relates to the field of aluminum foil production technology, specifically to a rolling oil blowing device for aluminum foil blank production. Background Technology

[0002] In the cold rolling process of aluminum foil, the main functions of rolling oil are: 1. Rolling oil forms a lubricating film between the rolls and the aluminum foil, which significantly reduces the friction on the contact surface with the aluminum foil blank, reduces roll wear, and extends equipment life; 2. During the cold rolling process, plastic deformation and friction generate heat. Rolling oil acts as a coolant to absorb and carry away the heat, preventing the aluminum foil and rolls from overheating and avoiding material performance degradation; 3. The lubricating film reduces surface scratches and defects, ensuring a smooth aluminum foil surface.

[0003] After aluminum foil is rolled, if rolling oil remains on the surface, it may form spots, oil film, or color difference, resulting in a decrease in surface smoothness and affecting product quality. Rolling oil on the surface of aluminum foil is usually removed by blowing. However, the blowing devices currently used cannot fully contact the surface of the aluminum foil during the one-time passage of the aluminum foil, resulting in rolling oil residue and incomplete blowing. Summary of the Invention

[0004] This invention addresses the problem that traditional purging devices for removing rolling oil from aluminum foil surfaces often fail to thoroughly remove the oil. It provides a purging device for aluminum foil blank production that reduces residual rolling oil on the aluminum foil surface and improves purging quality.

[0005] To solve the above problems, the technical solution of this utility model is:

[0006] A rolling oil purging device for aluminum foil blank production includes a box body, a first shell, and a second shell. The left and right side plates of the box body are symmetrically provided with through holes, and the bottom is connected to a drain pipe. The first shell is located inside the left part of the box body and below the through holes. The first shell is provided with an air pipe connected to the inside of the first shell. The top plate of the first shell is provided with a V-shaped hole. The first V-shaped hole is composed of two symmetrical holes, a first hole and a second hole. The rear end of the first hole is inclined to the right, and the upper end of the first hole is inclined to the right front. The opposite ends of the first hole and the second hole are connected. The second shell is located inside the right part of the box body and above the through holes. The second shell is provided with an air pipe connected to the inside of the second shell. The bottom plate of the second shell is provided with a V-shaped hole. The second V-shaped hole is composed of two symmetrical holes, a third hole and a fourth hole. The rear end of the third hole is inclined to the right, and the lower end of the third hole is inclined to the right front. The opposite ends of the third hole and the fourth hole are connected.

[0007] Furthermore, the outer bottom surface of the box is provided with support legs near the four corners; the inner bottom surface of the box is provided with a V-shaped groove, and the drain pipe passes through the middle of the V-shaped groove.

[0008] Furthermore, the front and rear ends of the housing slidably contact the front and rear inner surfaces of the box body, respectively. A screw is threadedly connected to the bottom plate of the box body. The upper end of the screw is rotatably connected to the bottom plate of the housing and the lower end is connected to a rotating plate. The air outlet of the air pipe movably penetrates the bottom plate of the box body and is fixedly connected to the bottom plate of the housing.

[0009] Furthermore, the front and rear ends of the second shell slide in contact with the front and rear inner surfaces of the box body, respectively. A screw rod is threadedly connected to the top plate of the box body. The lower end of the screw rod is rotatably connected to the top plate of the second shell, and the upper end is connected to a rotating plate. The air outlet of the second air pipe moves through the top plate of the box body and is fixedly connected to the top plate of the second shell.

[0010] Furthermore, the top surface of the top plate of the first shell is a sloped surface with the left side higher than the right side; the front side plate of the box is a transparent plate.

[0011] Furthermore, the distance between the front and rear ends of the first V-shaped hole is greater than the distance between the front and rear ends of the through hole, and the distance between the front and rear ends of the second V-shaped hole is greater than the distance between the front and rear ends of the through hole.

[0012] The beneficial effects of this utility model through the above technical solution are as follows:

[0013] In use, the aluminum foil moves within the housing, and compressed air forms an air knife through the V-shaped hole on the second housing. The downward-flowing air knife can quickly and comprehensively drive the rolling oil droplets on the top surface of the aluminum foil into the housing. Compressed air forms an air knife through the V-shaped hole on the first housing, and the upward-flowing air knife can quickly and comprehensively drive the rolling oil droplets on the bottom surface of the aluminum foil into the housing. This invention thoroughly and quickly removes the rolling oil from the aluminum foil.

[0014] The staggered arrangement of the V-shaped hole one and V-shaped hole two in this invention can prevent rolling oil residue from being caused by airflow turbulence at the edge of the aluminum foil. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0022] like Figures 1-5 As shown, a rolling oil purging device for aluminum foil blank production includes a box body 1, a shell 2, and a shell 3. The box body 1 is a hollow cuboid with its lower opening sealed by a bottom plate. Symmetrical through holes 4 are provided on the left and right side plates of the box body 1, and a drain pipe 5 connects to the bottom. The through holes 4 are rectangular holes. The shell 2 is a hollow cuboid located inside the left side of the box body 1, below the through holes 4. A vent pipe 6 connecting to the interior of the shell 2 is provided on the shell 2. A V-shaped hole 7 is provided on the top plate of the shell 2. The V-shaped hole 7 consists of two symmetrical holes, 7a and 7b, with the rear end of hole 7a tilted to the right. The upper end of the first hole 7a is inclined to the right front. The opposite ends of the first hole 7a and the second hole 7b are connected. The second shell 3 is a hollow cuboid. The second shell 3 is located inside the right part of the box 1 and above the through hole 4. The second shell 3 is provided with an air pipe 9 that connects to the inside of the second shell 3. The bottom plate of the second shell 3 is provided with a V-shaped hole 8. The V-shaped hole 8 is composed of two symmetrical holes 8a and 8b. The rear end of the third hole 8a is inclined to the right, and the lower end of the third hole 8a is inclined to the right front. The opposite ends of the third hole 8a and the fourth hole 8b are connected. The first hole 7a, the second hole 7b, the third hole 8a and the fourth hole 8b are all elongated holes.

[0023] Support legs 10 are provided near the four corners of the outer bottom surface of the box body 1; V-shaped grooves 15 are provided on the inner bottom surface of the box body 1, and the drain pipe 5 passes through the middle of the V-shaped grooves 15; the front and rear ends of the V-shaped grooves 15 pass through the front and rear ends of the bottom plate of the box body.

[0024] The front and rear ends of the housing 2 slide in contact with the front and rear inner surfaces of the box 1, respectively. A screw 11 is threadedly connected to the bottom plate of the box 1. The upper end of the screw 11 is rotatably connected to the bottom plate of the housing 2, and the lower end is connected to a rotating plate 12. The air outlet of the air pipe 6 movably passes through the bottom plate of the box 1. The bottom plate of the box 1 is provided with a through hole through which the air pipe 6 movably passes. The air outlet of the air pipe 6 passes through and is fixedly connected to the bottom plate of the housing 2.

[0025] The front and rear ends of the second housing 3 respectively slide in contact with the front and rear inner surfaces of the box 1. The top plate of the box 1 is threaded with a screw 13. The lower end of the screw 13 is rotatably connected to the top plate of the second housing 3, and the upper end is connected to a rotating plate 14. The air outlet of the second air pipe 9 movably passes through the top plate of the box 1. The top plate of the box 1 is provided with a through hole 2 through which the second air pipe 9 movably passes. The air outlet of the second air pipe 9 passes through and is fixedly connected to the top plate of the second housing 3.

[0026] The top surface of the top plate of the housing 2 is a slope that is higher on the left and lower on the right; the purpose is to facilitate the rolling oil dripping onto the top surface of the housing 2 to flow to the right into the box 1; the front plate of the box 1 is a transparent plate, and the front plate of the box 1 is a plate made of plexiglass.

[0027] The distance between the front and rear ends of the V-hole 7 is greater than the distance between the front and rear ends of the through hole 4, and the distance between the front and rear ends of the V-hole 8 is greater than the distance between the front and rear ends of the through hole 4.

[0028] The air tube 6 and air tube 9 selected in this utility model are both PU steel wire reinforced hoses, the purpose of which is to ensure that the compressed gas delivery is not affected after bending. The model of air tube 6 and air tube 9 is WH00785.

[0029] During use, the rolled aluminum foil ends pass sequentially through the through holes 4 on the right and left sides of the housing 1. The aluminum foil moves from right to left through the housing 1. Compressed air is introduced into the housing 2 3 through the air pipe 2 9. The compressed air in the housing 2 3 is discharged through the V-shaped hole 2 8, forming a downward-flowing V-shaped air knife. The front of the V-shaped air knife is discharged through the hole 3 8a. The lower end of the hole 3 8a is inclined to the right front. Therefore, the front of the V-shaped air knife contacts the front of the top of the aluminum foil. During the movement of the aluminum foil to the left, the rolling oil in front of the top of the aluminum foil flows and gathers towards the front end of the aluminum foil under the action of the air force in front of the V-shaped air knife, and drips into the lower part of the housing 1 through the front end of the aluminum foil. The rear of the V-shaped air knife... When the aluminum foil moves to the left, the rolling oil at the rear of the top surface of the aluminum foil flows and gathers towards the rear end of the aluminum foil under the action of the wind force at the rear of the V-shaped air knife, and drips into the lower part of the box 1 through the rear end of the aluminum foil. The V-shaped air knife can prevent the rolling oil from gathering in the middle of the aluminum foil. Moreover, the hole body 8a and hole body 8b that constitute the V-shaped hole 8 are set at an angle, so the top surface of the aluminum foil can receive more force from the V-shaped air knife. The rolling oil drips more quickly from the front and rear ends of the aluminum foil into the box 1. By rotating the screw 13 on the housing 23 and observing through the front side plate of the box, the distance between the housing 23 and the aluminum foil can be controlled to increase or decrease the wind force on the top surface of the aluminum foil. It is convenient to use.

[0030] Compressed air is introduced into the housing 2 through the air pipe 6. The compressed air in the housing 2 is discharged through the V-shaped hole 7, forming an upward-flowing V-shaped air knife. The V-shaped air knife contacts the rolling oil on the bottom surface of the aluminum foil. The front part of the V-shaped air knife is discharged through the orifice 7a. The upper end of the orifice 7a is inclined to the right and forward. Therefore, the front part of the V-shaped air knife contacts the front part of the bottom surface of the aluminum foil and pushes the rolling oil in front of the bottom surface of the aluminum foil to flow and collect towards the front end of the aluminum foil, and drips into the lower part of the housing 1 through the front end of the aluminum foil. Similarly, the rear part of the V-shaped air knife contacts the rear part of the bottom surface of the aluminum foil and pushes the top of the aluminum foil... The rolling oil at the rear end flows and gathers towards the rear end of the aluminum foil, and drips into the lower part of the box 1 through the rear end of the aluminum foil. The V-shaped air knife can prevent the rolling oil from gathering in the middle of the aluminum foil. The hole body 7a and hole body 7b of the V-shaped hole 7 are set at an angle, so that the bottom surface of the aluminum foil can be subjected to more force from the V-shaped air knife, which can make the rolling oil drip into the box 1 more quickly through the front and rear ends of the aluminum foil. By rotating the screw 11 on the housing 2 and observing through the front side plate of the box, the distance between the housing 2 and the aluminum foil can be controlled to increase or decrease the wind force on the bottom surface of the aluminum foil.

[0031] The staggered arrangement of housing 1 2 and housing 2 3 can prevent the airflow formed by the air knife through V-hole 1 7 and V-hole 2 8 from converging, avoid the formation of turbulence, and prevent the edge of the aluminum foil from being affected by turbulence, resulting in rolling oil residue.

[0032] The rolling oil inside the tank 1 is discharged and collected through the drain pipe 5 to avoid waste of the rolling oil.

[0033] The preferred embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Any equivalent or equivalent modifications or substitutions to the technical solutions of the present utility model without departing from the spirit of the present utility model or the scope of disclosure shall fall within the protection scope of the present utility model.
