Problems solved by technology

Disadvantages: It is still impossible to solve the defects of pores and gaps on the surface of the rolled aluminum foil caused by the fine impurities of the aluminum itself and the uncleanness of the roll surface during the aluminum foil rolling process, and these pores and gaps exist in the aluminum foil. When the communication optical cable and cable are shielded and wrapped, it will cause the attenuation of the communication signal, the interference of the external signal to the communication signal, and the occurrence of the return loss phenomenon.

Embodiment 1

[0009] Example 1: Refer to the attached figure 1 . An aluminum foil air gap repair production line. An electrostatic friction generator 12, a nano-coating device 5, and a nano-aluminum rolling forming device 3 are sequentially arranged between the aluminum foil unwinding roll 13 and the aluminum foil winding roll 1; the electrostatic friction generator 12, nano The coating device 5 and the nano-aluminum rolling forming device 3 respectively have inlets and outlets for the aluminum foil to enter and exit. After the aluminum foil is discharged from the aluminum foil winding roller 1, the aluminum foil is discharged from the aluminum foil winding roller 1, and then passes through the electrostatic friction generator 12, After the nano-coating device 5 and the nano-aluminum rolling and forming device 3, the repaired aluminum foil is wound by the aluminum foil winding roller 13, and the aluminum foil winding roller 13 is driven to rotate by a geared motor. That is, the aluminum foi...

Embodiment 2

[0013] Example 2: On the basis of Example 1, a filling method of an aluminum foil air gap repair production line. When working, start the motor switch, and the motor drives the aluminum foil winding roller 1 and the counter-roller in the nano aluminum rolling and forming device 3 The pressing roller 4 rotates, and the aluminum foil enters the electrostatic friction generator 12 from the aluminum foil unwinding roller 13 under the traction of the aluminum foil winding roller 1. After the forced friction of the upper and lower fluff pads 10 in the electrostatic friction generator 12, static electricity is generated on the surface of the aluminum foil. The aluminum foil with static electricity on the surface passes through the nano-coating device 5, adsorbing the nano-aluminum in the nano-coating device 5 on its surface, and then passes through the roller 4 in the nano-aluminum rolling forming device 3. The nano-aluminum is compacted by the counter-rolling roller to repair the air ...

Abstract

The invention relates to an aluminum foil air gap filling production line and a filling method. An electrostatic friction generator, a nanometer coating device and a nanometer aluminum rolling molding device are arranged between an aluminum foil uncoiling roller and an aluminum foil coiling roller in sequence, and are respectively provided with ports for accessing an aluminum foil; after the aluminum foil is released by the aluminum foil coiling roller and passes through the electrostatic friction generator, the nanometer coating device and the nanometer aluminum rolling molding device in sequence, the repaired aluminum foil is coiled by the aluminum foil coiling roller; and the aluminum foil coiling roller is driven by a speed reducing motor to rotate. The aluminum foil air gap filling production line has the following advantages: (1) an aluminum foil surface air gap is filled by nanometer aluminum with the same attribute, so that the aluminum foil compactness is greatly improved, and a low-grade aluminum foil is upgraded to a high-grade aluminum foil to largely increase the additional value; and (2) a communication aluminum foil, after filling repair, is high in insulation strength and excellent in shielding effect, and prevents the generation of return loss phenomenon to generate unexpected technical effect and economic benefit.

Description

Technical field [0001] The invention relates to an aluminum foil air gap repair production line and a filling method that can effectively fill and seal the permeable pores and gaps existing on the aluminum foil surface, and can fill and repair the grooves and wire grooves existing on the aluminum foil surface itself. Use aluminum foil secondary processing manufacturing field. Background technique [0002] CN103785800A, the name "a production method of double zero aluminum foil", includes the steps of degassing and removing slag from the molten aluminum alloy and then casting and rolling into a cast-rolled coil with a thickness of 6.5-8.0mm. The step of cold rolling into an aluminum coil with a thickness of 2.0 to 3.0 mm. The aluminum coil after the first cold rolling is subjected to the first heat treatment step at a temperature of 450 to 550°C for 15 to 20 hours. The aluminum coil after the primary heat treatment is cold-rolled for the second time to form an aluminum coil with ...
