Technical Field

[0001] The invention relates to the technical field of copper foil processing, in particular to a copper foil coating and drying line. Background Art

[0002] Copper foil coating and drying is an important part of the copper foil coating process. It involves drying the material coated on the surface of the copper foil to remove the solvent, solidify the coating, and ensure good bonding between the coating and the copper foil substrate. Its main purpose is to remove the solvent or moisture in the coating, solidify the coating on the surface of the copper foil, and form a composite film with specific properties.

[0003] After searching, a Chinese patent (publication number: CN106196960B) discloses a swing-combined copper foil drying device, in which the patented drying device is arranged on a frame of a heating roller drive shaft, and the copper foil can be between the heating roller and the drying device; the drying device includes: a swing drying arm, which is hinged on a side panel of the frame, a ventilation duct is arranged inside the drying arm, and an opening for blowing air is arranged at its lower end; the drying arm is controlled to swing by a motor; and the drying arm can also rotate on a rotating disk.

[0004] When drying copper foil, since a constant temperature is usually maintained in the drying device, when the copper foil enters the drying device, the temperature shock at the initial stage of drying is relatively large, which is not conducive to the combination of the coating and the copper foil substrate. Therefore, how to effectively reduce the temperature shock when the copper foil enters the drying device is one of the research and development directions of the copper foil drying device. Therefore, the present invention proposes a copper foil coating drying line. Summary of the invention

[0005] The object of the present invention is to provide a copper foil coating and drying line.

[0006] The technical problem solved by the present invention is: how to effectively reduce the temperature shock of the copper foil when it enters the interior of the drying device.

[0007] The present invention can be implemented by the following technical scheme: a copper foil coating drying line, comprising a drying box, wherein a first conveying assembly and a heating assembly are installed inside the drying box, and an air supply assembly is installed on the top of the drying box, the copper foil moves inside the drying box through the first conveying assembly, and the heating assembly heats the inside of the drying box, so that the copper foil is dried after entering the drying box;

[0016] A further technical improvement of the present invention is that a lifting assembly is installed inside the box body, and the output end of the lifting assembly is connected to the split bin. After the lifting assembly is started, it drives the split bin to move in the vertical direction, thereby changing the position of the partition plate on one side of the air outlet bin, and then changing the area of ​​the first bin body and the second bin body connected to the air outlet bin.
