Description

Technical Field

[0001] The utility model belongs to the technical field of unwinders, and specifically relates to a copper foil unwinder. Background Art

[0002] In the process of recycling waste foil, the whole roll of copper foil is taken out of the paper tube by the way of manual foil killing. Although manual foil killing reduces the extra expenditure cost of the enterprise, there are also certain safety hazards, such as copper foil cutting and blade scratching of workers, etc. Scratching the paper tube also affects the secondary utilization of the paper tube, and some copper foil debris generated during the foil killing process also reduces the recovery rate of copper foil to a certain extent.

[0003] Such as a copper foil unwinder with the publication number of CN 219771300 U, which includes: a fixed seat; two support plates, and the two support plates are fixedly connected to both ends of the fixed base; an arc-shaped opening groove, and the arc-shaped opening groove is opened at the top of one support plate for carrying the paper tube of the copper foil; a hydraulic rod fixing plate, and the hydraulic rod fixing plate is installed at the top of the other support plate; a hydraulic rod, and the hydraulic rod is fixedly connected to the hydraulic rod fixing plate and extends towards the arc-shaped opening groove; a driving mechanism, and the driving mechanism is used to drive the piston rod of the hydraulic rod to move back and forth; a lifting bracket, and the lifting bracket is movably connected above the fixed base. The beneficial effect of the utility model is that the way of separating the paper tube from the copper foil alone is adopted, which quickly solves the problem of waste foil recycling, liberates labor productivity and improves the waste foil recycling efficiency; the lifting bracket ensures the use of copper foils with different roll diameters, and it can adaptively adjust the central position of the paper tube and the hydraulic rod to meet the use of copper foil products with different specifications;

[0004] This copper foil unwinder realizes the unwinding operation by directly squeezing the copper foil paper roll with a hydraulic rod. However, it is found in actual operation that there is a large frictional force between the paper roll and the copper foil. During the process of squeezing the paper roll with the hydraulic rod, the copper foil will move along with the paper roll, resulting in the paper roll being bent and not easily extruded from the inside of the copper foil. In order to solve the above problems, a copper foil unwinder is proposed. Content of the Utility Model
