Description

Technical Field

[0001] The invention belongs to the technical field of copper foil rolling mill equipment, and in particular relates to a copper foil six-roller rolling mill strip surface sweeping device. Background Art

[0002] When the copper foil rolling mill rolls the copper strip, in order to reduce the friction coefficient and wear, and at the same time take away the large amount of heat generated during the rolling process of the copper foil, a large amount of rolling oil is added during the rolling process. Through the cooling effect of the rolling oil, the temperature of the copper foil can be effectively controlled, thereby stabilizing the dimensional accuracy. The rolling oil can also make the surface of the copper foil smoother and improve the surface finish. After the copper foil is rolled, the residual rolling oil on the surface of the copper foil needs to be removed in time. In the prior art, the surface of the copper foil is purged with compressed air to blow the rolling oil away from the surface of the copper foil. During purging, since the blowing nozzle maintains a fixed angle to purge the upper and lower surfaces of the copper foil, the rolling oil always moves along the copper foil surface in a fixed direction and angle and is blown away from the copper foil strip surface. The purging gases on the upper and lower sides of the copper foil strip collide at the edge of the copper foil strip, causing the purging gases on the copper foil surface and the side of the copper foil strip in the edge area to become turbulent. Due to the surface tension of the rolling oil, the rolling oil on both sides of the copper foil strip will adhere and remain, so there will still be rolling oil remaining on the copper foil surface. Summary of the invention

[0003] The purpose of the present invention is to solve the problem in the prior art that the rolling oil on the surface of the copper foil rolling mill is not completely purged and still remains after rolling the copper foil, and to propose a surface purging device for the strip of a copper foil six-roll rolling mill.

[0032] The mounting frame 3 is provided with a driving mechanism for driving the surface blowing air knife 5 to swing and blow the surface of the copper foil strip 2 .

The groove 26 includes a first spiral groove 27, an upper arc groove 28, a second spiral groove 29 and a lower arc groove 30 which are connected in sequence from head to tail. The helical angle of the first spiral groove 27 is equal to the helical angle of the second spiral groove 29. In this embodiment, the helical angle is 90°. The upper arc groove 28 is circumferentially arranged around the drive shaft 21, and the upper arc groove 28 corresponds to a quarter of the arc length. The lower arc groove 30 is circumferentially arranged around the drive shaft 21, and the lower arc groove 30 corresponds to a quarter of the arc length. The first spiral groove 27 has a helical angle equal to the helical angle of the second spiral groove 29. In this embodiment, the helical angle is 90°. The upper arc groove 28 is circumferentially arranged around the drive shaft 21, and the upper arc groove 28 corresponds to a quarter of the arc length. The rotation direction of the groove 27 is opposite to that of the second spiral groove 29. The driven sleeve 22 is provided with an adapting spiral trajectory hole 31. The adapting spiral trajectory hole 31 has the same rotation direction and the same spiral angle as the first spiral groove 27. The positioning cover 20 is provided with a guide groove 24. A sliding block 32 is slidably arranged in the guide groove 24. The sliding block 32 is provided with a guide column 33 that passes through the adapting spiral trajectory hole 31 and is located in the driving trajectory groove 26. When the driving shaft 21 rotates, it drives the driven sleeve 22 to swing back and forth.

[0033] Working principle: After the copper foil six-roller rolling mill rolls the copper foil strip 2, the copper foil strip 2 is wound around the support roller 4 by the rolling mill body 1. The support roller 4 rotates under the power of the rolling mill body 1, driving the copper foil strip 2 to move. At the same time, the transmission shaft 18 rotates under the action of the sprocket chain assembly 25, and the driving shaft 21 rotates under the transmission action of the bevel gear set 34. The rotation of the driving shaft 21 drives the guide column 33 to move along the driving track groove 26 on the driving shaft 21. At the same time, the sliding block 32 moves up and down along the guide groove 24. The guide column 33 moves along the driving track groove 26 while driving the driven sleeve 22 to move, and the driven sleeve 22 drives the surface blowing air knife 5 to swing back and forth.

[0034] The working principle of the transmission assembly is described below by using specific states. Assume that the initial state is that the guide post 33 is located at the connection position between the lower arc groove 30 and the first spiral groove 27. Figure 7 , Figure 8 As shown, at this time, the first spiral groove 27 is fully matched with the matching spiral trajectory hole 31, and the guide column 33 is located at the lowermost end of the matching spiral trajectory hole 31. When the drive shaft 21 rotates, the guide column 33 slides upward along the guide groove 24 under the action of the first spiral groove 27 to the connection position of the first spiral groove 27 and the upper arc groove 28. During this process, the guide column 33 slides upward along the guide groove 24, so that the guide column 33 reacts to the matching spiral trajectory hole 31, so that the driven sleeve 22 rotates relative to the guide column 33, and the driven sleeve 22 rotates in the same direction as the drive shaft 21 until the guide column 33 moves to the uppermost end of the matching spiral trajectory hole 31. Then the drive shaft 21 continues to rotate, and at this time the guide column 33 is located in the upper arc groove 28. The drive shaft 21 rotates until the guide column 33 is located at the connection position between the upper arc groove 28 and the second spiral groove 29. During this process, the position of the guide column 33 remains unchanged and is still at the upper end of the guide groove 24. Only the drive shaft 21 rotates, and the driven sleeve 22 does not rotate relative to the guide column 33. Then the drive shaft 21 continues to rotate, and the guide column 33 slides downward along the guide groove 24 to the connection position of the second spiral groove 29 and the lower arc groove 30 under the action of the second spiral groove 29. During this process, the guide column 33 slides downward along the guide groove 24, so that the guide column 33 reacts to the matching spiral track hole 31, so that the driven sleeve 22 rotates in the opposite direction; then the drive shaft 21 continues to rotate, and at this time the guide column 33 is located in the lower arc groove 30, and the drive shaft 21 rotates to the point where the guide column 33 is located at the connection position of the lower arc groove 30 and the first spiral groove 27. During this process, the guide column 33 is located at the lower end of the guide groove 24 and remains in place, so the driven sleeve 22 does not rotate.

[0035] The above process is a reciprocating rotation process. During the unidirectional rotation of the driving shaft 21, the driven sleeve 22 is swung, thereby driving the surface blowing air knife 5 to oscillate back and forth.

[0036] The surface blowing air knife 5 swings back and forth while driving the side blowing air knife 6 to slide back and forth along the edge of the copper foil strip.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Within the technical scope disclosed by the present invention, technicians familiar with the technical field can make equivalent replacements or changes based on the technical scheme and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
