Description

Technical Field

[0001] The utility model relates to the field of die cutting machines, in particular to a cutting device used for producing mobile phone protective films. Background Art

[0002] Die-cutting machines play a very important role in the production of mobile phone protective films. They are mainly used for die-cutting (full cutting, half cutting), creasing, hot stamping, laminating and automatic waste discharge of non-metallic materials, self-adhesive stickers, EVA, double-sided adhesive tapes, electronics, mobile phone rubber pads, etc. For the production of mobile phone protective films, die-cutting machines can achieve high-precision cutting to ensure the flatness and precision of the product edges. The working principle of the die-cutting machine is to use a template carved from a steel knife, a hardware mold or a steel plate, and apply a certain amount of pressure through the stamping plate to roll and cut the printed product or cardboard into the required shape. In the production of mobile phone protective films, the die-cutting machine can accurately cut the protective film according to the preset graphics and size to meet the needs of different models of mobile phones. In actual use, since the sizes of protective films required for different mobile phones are different, different sizes of die cutters are required when producing different models of mobile phone protective films. At this time, the die cutter needs to be replaced, and the die cutter of the traditional die cutter is fixed on the upper pressure plate. Therefore, when replacing the die cutter, the upper pressure plate has to be removed, which makes the replacement process of the die cutter more troublesome, time-consuming and laborious. In the existing patent application with application number CN201922209934.7, a die cutter for acrylic protective film processing is proposed. Although it can increase the number of second platforms as needed, and then increase the width of the cutting platform to adapt to the cutting edges of membranes of different widths, avoiding the disassembly and replacement of the die cutter, the disassembly and assembly process of the second platform is also more cumbersome and troublesome. Therefore, a cutting device for the production of mobile phone protective films is needed to solve the above problems. Utility Model Content

[0003] The main purpose of the utility model is to provide a cutting device for producing mobile phone protective films, which can effectively solve the problems in the background technology.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

The connecting plate 11 has two and is symmetrically fixedly mounted on the upper end of the die-cutting knife body 10. A fixing assembly 5 is movably mounted on the upper pressing plate 3, and the fixing assembly 5 is composed of a fixing spring 13, a base plate 14, a T-shaped slider 15 and a fixing plug plate 16. The base plate 14 has two and is symmetrically fixedly mounted on both ends of the fixing spring 13. The T-shaped slider 15 has two and is fixedly mounted on the lower ends of the two base plates 14 respectively. The fixing plug plate 16 has two and is fixedly mounted on the outer ends of the two base plates 14 respectively, and the fixing plug plate 16 can be inserted into the connecting plate 11. The larger die-cutting knife assembly 4 is sleeved on the outer side of the smaller die-cutting knife assembly 4. The die-cutting knife body 10 on the die-cutting knife assembly 4 is retracted in the storage groove 7 opened at the lower end of the upper pressing plate 3. The connecting plate 11 is movably mounted in the connecting groove 8. Two fixing slots 12 are opened on the connecting plate 11. The fixing spring 13 and the base plate 14 are both located above the upper pressing plate 3, and the T-shaped sliding block 15 is slidably installed in the T-shaped guide groove 9 opened at the upper end of the upper pressing plate 3, and the fixing plug plate 16 can be inserted into the fixing slot 12 opened on the connecting plate 11. By setting the die-cutting knife assembly 4 and the fixing assembly 5, they cooperate with each other. When the die-cutting knife body 10 needs to be replaced, it is only necessary to first move the two base plates 14 on the fixing assembly 5 close to each other, so that the fixing plug plate 16 is moved out of the fixing slot 12, thereby releasing the fixation of the die-cutting knife assembly 4, and then the die-cutting knife body 10 that is not needed can be pushed upward to be completely retracted into the storage groove 7, and then the die-cutting knife body 10 that meets the use requirements is pushed downward to be moved out of the storage groove 7, and finally the die-cutting knife assembly 4 is fixed by the fixing assembly 5, and the replacement of the die-cutting knife body 10 is completed at this time.

During this process, the hydraulic cylinder 2 can be started, so that the hydraulic cylinder 2 can be used to drive the upper pressure plate 3 to move up and down reciprocatingly. When the upper pressure plate 3 moves downward, the die-cutting knife body 10 located outside the receiving groove 7 will press the film material on the upper end of the cutting table 6, so that a slit that matches the size of the mobile phone is generated on the film material, and finally the protective film in the slit is separated from the film material, and a protective film that matches the size of the mobile phone can be obtained.
