Description

Technical Field

[0001] The utility model relates to the technical field of slitting equipment, in particular to a copper foil unwinding and chip removing device for a slitting machine. Background Art

[0002] PCBs, which provide electrical connections for electronic components, typically use copper foil as a conductor. Copper foil easily adheres to the insulating layer and forms a circuit pattern after corrosion. During the copper foil production process, a copper foil slitting machine is used to slit the foil according to the required specifications for the PCB.

[0003] The invention patent, currently published with the publication number CN118004815B, discloses a copper foil slitting machine. The copper foil slitting machine includes a reeling device, a guide device, a slitting device, and a reeling device. The reeling device includes a drive mechanism and an adjusting roller and a reeling roller spaced apart. The adjusting roller is disposed between the reeling roller and the slitting device, and the horizontal distance between the adjusting roller and the reeling roller is within a first preset range. At least one of the adjusting roller and the reeling roller is connected to the drive mechanism, and the drive mechanism can drive at least one of the adjusting roller and the reeling roller to continuously move so that the horizontal distance between the adjusting roller and the copper foil roll remains within a second preset range. The adjusting roller and the reeling roller are relatively close to each other, which can reduce the distance between the adjusting roller and the reeling roller, thereby reducing the length of the copper foil between the adjusting roller and the reeling roller. That is, the overhang length of the copper foil between the adjusting roller and the reeling roller is reduced to increase the tension of the copper foil, thereby preventing interlayer misalignment.

[0004] During use, the existing copper foil slitting equipment uses a copper foil unwinding device to unwind the copper foil coil, and the copper foil coil then enters the slitting mechanism for slitting. The debris adhered to the surface of the copper foil coil still adheres to the surface of the copper foil strip after slitting. After the copper foil strip is cut into thin strips, it is more difficult to clean the debris. In order to solve the above problem, this application proposes a copper foil unwinding and debris removal device for a slitting machine. Utility Model Content

[0032] In this embodiment, if Figure 1As shown, a rotating shaft 14 is provided on the cavity wall surface where the upper dust hood 1 and the lower dust hood 2 are close to each other. The rotating shaft 14 is respectively located at the coil discharge of the upper dust hood 1 and the lower dust hood 2. A scraper 15 is welded on the surface of the rotating shaft 14. The two ends of the scraper 15 are respectively located at the two ends of the inner cavity of the upper dust hood 1 and the lower dust hood 2.
