Description

Technical Field

[0001] The utility model relates to the technical field of cutting devices, in particular to a reflective film cutting device. Background Art

[0002] Reflective film is a kind of retro-reflective material that has been made into a thin film and can be used directly. It is also the most widely used retro-reflective material. During the production process of reflective film, it needs to be cut into specified lengths according to specific requirements.

[0003] In the prior art, a reflective film processing and cutting device with publication number CN213165520U adopts the scheme of "the reflective film processing and cutting device, the upper surface of the workbench is provided with a cutting tool, the upper surface of the workbench is fixedly connected with a cutting platform, the upper surface of the workbench is provided with a slide rail, the outer surface of the slide rail is threadedly connected with a sleeve, the outer surface of the end of the slide rail away from the fixed rod is slidably connected with a sliding plate, the end of the sliding plate is fixedly connected with a fixed T-shaped plate, the upper surface of the fixed T-shaped plate is fixedly connected with a sliding rod, the outer surface of the sliding rod is slidably connected with a movable T-shaped plate, and the outer surface of the sliding rod is movably sleeved with a spring". When the scheme is in use, the sliding plate slides on the slide rail, and when it contacts the sleeve, the cutting tool is pressed down for cutting. After cutting is completed, the movable T-shaped plate is released, and the reflective film is removed. Without adjusting the sleeve, the above operation is repeated to obtain a large number of reflective films of the same length.
