Abstract
Description
Technical Field
[0001] The utility model relates to the field of protective film manufacturing, in particular to a die-cutting device for mobile phone films. Background Art
[0002] Smartphones are touch-sensitive electronic devices. Since they need to be touched frequently during use, the screen of smartphones is easily scratched. To avoid screen damage, a layer of mobile phone protective film is usually attached to the screen. Existing mobile phone films are generally produced by up and down punching die-cutting machines. The raw film roll is fed in a step-by-step manner. When it is fed to the die-cutting equipment, the feeding stops and continues after the die-cutting is completed.
[0003] Since the raw material film is ductile, the raw material film cannot be cut immediately when the cutter contacts the raw material film. The cutter will generate a certain pulling force on the raw material film, which may cause the raw material to be stretched to a certain extent, resulting in a certain error in the size of the finished film after cutting, which does not meet the precision requirements. At the same time, excessive pulling force may also cause the raw material film on one side that has not been die-cut to be stretched excessively, resulting in some quality problems. Therefore, in order to ensure the uniform precision requirements of the finished product, it is best to press the surrounding side of the raw material film before cutting; the existing device for die-cutting mobile phone film has the disadvantage of low automation when working. Its pressing and cutting are two different processes and cannot be performed at the same time, that is, after the raw material film is in place, the pressing device is first controlled to press the raw material film, and then the cutting device is controlled to press down for cutting, which is time-consuming and labor-intensive, low in efficiency, and will cause the overall structure of the equipment to be more complicated. In addition, after the existing die-cutting device completes a die-cutting, it is necessary to manually remove the finished film on the workbench, which wastes a lot of time, is inefficient, and greatly reduces the company's profits. Utility Model Content
[0004] In view of this, in order to solve the problems existing in the above-mentioned prior art, the utility model provides a die-cutting device for a mobile phone film.
