Description

Technical Field

[0001] The utility model relates to the technical field of aluminum-plastic film processing, in particular to an aluminum film cutting device. Background Art

[0002] Aluminum-plastic film has good ductility and high heat-sealing strength. It is not easy to cause invisible fractures at the corners, thus ensuring that the battery is not easily bulged. At the same time, it has good resistance to electrolyte corrosion, and it has gradually become the preferred material for battery packaging.

[0003] The application number "CN201820271287.5" discloses an aluminum-plastic film cutting device, which is slidably mounted on a base, and the cutting device comprises a first slider, a second slider, a pressing block and a cutting knife, the first slider and the second slider are slidably mounted on the base, and the sliding directions of the first slider and the second slider are arranged in parallel, and the two ends of the pressing block are slidably mounted on the first slider and the second slider to move against and away from the base, and the pressing block is provided with a cutting knife slot running through its end surface, and the cutting knife is inserted in the cutting knife slot and can move along the length direction of the cutting knife slot; the aluminum-plastic film cutting device proposed by the utility model presses the aluminum-plastic film by pressing the pressing block downward, and then places the cutting knife in the cutting knife slot of the horizontal pressing block, presses the cutting knife downward and moves along the cutting knife slot to cut the aluminum-plastic film, such a cutting method has good safety, high accuracy, saves time and labor, and the device has no other auxiliary power devices, is simple to assemble, simple to use, and is also relatively convenient to carry.

[0004] This patent cannot tighten the aluminum-plastic film well when cutting it, which makes it easy to wrinkle and affect the cutting effect. At the same time, after the aluminum-plastic film is cut, the pressing block moves upward, causing the cut aluminum-plastic film to move to both sides under the tension, resulting in the need for workers to re-pass one end of the aluminum-plastic film through the cutting device and then wind it around the winding device. There are many preparation steps after cutting, which is time-consuming and labor-intensive. Utility Model Content
