Description

Technical Field

[0001] The present invention relates to the technical field of copper foil generators, and particularly to an integrated drying and blowing device for a copper foil generator and a using method thereof. Background Art

[0002] In the production process of electrolytic copper foil, first, a copper foil is formed on the surface of a cathode roller, and then it is peeled off and driven by a roller system on the anti-oxidation machine table of the copper foil generator, and then undergoes anti-oxidation, drying and other treatments before being wound up. When the copper foil passes through the anti-oxidation tank, the liquid on the surface of the copper foil cannot be squeezed dry by the squeezing roller, and often needs to be dried. On the existing copper foil generator, the drying device and the blowing device are separately arranged, occupying a large space. The drying efficiency of the drying device is poor, the temperature cannot be monitored in real time, and the hot air cannot be discharged, which affects the surrounding rubber-coated rollers. Moreover, the blowing device blows directly on the foil surface, causing large fluctuations in the foil surface and posing a risk of edge tearing.

[0003] Chinese Utility Model Patent Publication No. CN218666336U discloses a copper foil generator, which includes a frame, a peeling device, a cleaning device, a slitting device, an anti-oxidation device and a winding device. A copper foil generating device is arranged on the frame for electrolytic copper foil production, and the frame has multiple processing stations from front to back; the peeling device, the cleaning device, the slitting device and the anti-oxidation device are arranged in sequence from front to back. This patent simply integrates the exhaust device, the drying device and the blowing device, but does not solve the problem of the foil surface shaking caused by the blowing device blowing directly on the foil surface. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the existing blowing device blows directly on the foil surface, causing the foil surface to shake. Therefore, an integrated drying and blowing device for a copper foil generator and a using method thereof that can offset the shaking of the copper foil are provided.

[0005] The technical solution of the present invention is: a drying and blowing integrated device for a copper foil making machine, including: a drying device arranged on the anti-oxidation machine table of the copper foil making machine for drying the passing copper foil, a blowing device and an air extraction device located on both sides of the drying device. The blowing device includes: two blowing brackets, each blowing bracket including inclined surfaces extending upward and downward respectively; two fan mounting covers, both ends of the two fan mounting covers being fixedly connected to the inclined surfaces of the two blowing brackets; a rotating cavity, the rotating cavity being located inside the fan mounting cover and rotatably connected to the inclined surfaces of the two blowing brackets at both ends, through holes being uniformly formed on the surface of the rotating cavity; an air extraction cylinder body, the air extraction cylinder body being concentrically installed in the rotating cavity; a strip-shaped opening, the strip-shaped opening being formed on the surface of the air extraction cylinder body and distributed along the axial direction of the air extraction cylinder body; a flip cover, the flip cover being hinged on the strip-shaped opening; an air extraction port, the air extraction port being axially formed on the surface of the air extraction cylinder body and opposite to the strip-shaped opening; a blowing cylinder body, the blowing cylinder body being concentrically installed in the air extraction cylinder body; a blowing port, the blowing port being formed at the bottom of the blowing cylinder body; a driving mechanism, the driving mechanism driving the rotating cavity and the air extraction cylinder body to rotate.

[0006] An improvement to the above solution is that a counterweight is installed on the flip cover.

[0007] In the above solution, one end of the air extraction cylinder body is connected to an air pump, and one end of the blowing cylinder body is connected to a fan.

[0008] In the above solution, the inclination angle of the inclined surface is 15°.

[0009] In the above solution, the drying device includes an oven upper cover, an oven main body, oven side covers, heating tube brackets and heating tubes. The oven upper cover, the oven side covers and the oven main body form a rectangular cavity. Two opposite side surfaces of the oven main body are respectively provided with a foil inlet and a foil outlet for the copper foil to enter and exit. The heating tube brackets are fixedly connected to the inner surface of the oven upper cover, and the heating tubes are fixed on the heating tube brackets.

[0010] In the above solution, the air extraction device includes an air extraction pipe assembly and a wind baffle. The air extraction pipe assembly is composed of an air extraction pipe and a mounting rack. The mounting rack is installed on the upper and lower sides of the foil inlet. The air extraction pipe is located inside the mounting rack and is communicated with the inside of the drying device.

[0011] A further improvement to the above solution is that a wind baffle is fixedly connected to the outside of the mounting rack.

[0012] The usage method of the integrated drying and blowing device for a copper foil machine includes the following steps: The copper foil enters the drying device through the air extraction device for drying. When it comes out of the drying device, the driving mechanism is started. The driving mechanism drives the rotating cavity and the air extraction cylinder to rotate around the blowing cylinder. At the same time, air is extracted from one end of the air extraction cylinder, and air is blown into from one end of the blowing cylinder. When the air extraction cylinder rotates to the position where the strip-shaped opening is at the lowest end, the flip cover opens due to its own weight. The air in the blowing cylinder acts on the surface of the copper foil through the air outlet, the strip-shaped opening, and the through hole. When the air extraction cylinder rotates to the position where the strip-shaped opening is at the highest end, the flip cover closes due to its own weight, and the air extraction port faces the surface of the copper foil to extract air from the surface of the copper foil.

[0013] The beneficial effect of the present invention is that through the cooperation of the air extraction cylinder and the blowing cylinder, a periodic operation of blowing or extracting air from the upper and lower directions on the copper foil is carried out simultaneously. The synchronous rotation of the two air extraction cylinders and the rotating cavity on the two inclined surfaces in the up and down directions, and the acting forces in the up and down directions act on the surface of the copper foil synchronously, offsetting the impact force, ensuring the stability of the copper foil, and at the same time improving the blowing effect. Whether it is air extraction or blowing, through the diversion of the through holes on the surface of the rotating cavity, the acting forces generated by blowing or extracting air act uniformly on the surface of the copper foil, and the acting range is large.

Specifically, one end of the exhaust cylinder is connected to an air pump, and one end of the blowing cylinder is connected to a fan.

[0026] It should be noted that the rotating cavity, the exhaust cylinder, and the blowing cylinder cooperate with the slopes, that is, two rotating cavities, exhaust cylinders, and blowing cylinders are correspondingly distributed on the two slopes. In this way, when the copper foil passes through, the two exhaust cylinders on the upper and lower slopes simultaneously exhaust air from it, and the two blowing cylinders simultaneously blow air on it, and it is carried out periodically.

[0027] The two sides and the lower side of the oven main body 21 are composed of heat insulation plates welded by rectangular pipes and steel plates. The inner side of the heat insulation plates is filled with heat preservation cotton. A heating pipe support 24 is arranged inside the oven main body 21. The bottom is an installation frame welded by channel steel. The oven upper cover 22 is installed on the upper side of the oven main body 21 through a stainless steel hinge. The oven upper cover is welded by rectangular pipes and steel plates. A temperature sensor is arranged on the top of the oven upper cover 22 to detect the temperature change of the oven in real time. Handles are arranged on the front and rear sides of the oven upper cover 22. A heating pipe support 24 is arranged at the bottom of the oven upper cover. The oven side cover 23 is installed on the front and rear sides of the oven main body 21 through a stainless steel hinge. The oven side cover 23 is a square welded by steel plates. The heating pipe 25 is installed in the drying device, with a part arranged on the oven upper cover 22 and a part arranged inside the oven main body 21.

[0028] The blowing device 3 is arranged on the side of the foil outlet of the drying device and is installed on the drying device through a blowing support 31.

[0030] As a preferred example of the present invention, a counterweight is installed on the flip cover, and the flip cover can be quickly opened or closed by using the counterweight, and the reaction is more sensitive.

[0031] As Figures 8-9 shown, the usage method of the integrated drying and blowing device of the copper foil machine includes the following steps: The copper foil enters the drying device through the exhaust device for drying. When it comes out of the drying device, the driving mechanism is started. The driving mechanism drives the rotating cavity and the exhaust cylinder body to rotate around the blowing cylinder body. The blowing cylinder body remains stationary, and the air outlet is always downward. At the same time, air is exhausted from one end of the exhaust cylinder body, and air is blown into from one end of the blowing cylinder body. When the exhaust cylinder body rotates to the position where the strip-shaped opening is at the lowest end, the flip cover opens due to its own weight. The air of the blowing cylinder body acts on the surface of the copper foil through the air outlet, the strip-shaped opening, and the through hole. The exhaust port is at the highest point, and part of the drawn air is discharged from the strip-shaped opening to enhance the blowing effect. When the exhaust cylinder body rotates to the position where the strip-shaped opening is at the highest end, the flip cover closes due to its own weight. The strip-shaped opening is blocked by the exhaust cylinder body, and the exhaust port is facing the surface of the copper foil to exhaust air from the surface of the copper foil.
