A die-cutting knife 11 is fixedly installed at the bottom of the plurality of mounting frames 10. The die-cutting knife 11 is connected and fixed to the mounting frame 10 by mounting bolts. The user can adjust the die-cutting specifications of the OCA optical glue by increasing or decreasing the number of die-cutting knives 11 installed between each mounting frame 10 to meet different production needs.

[0023] Both sides of the mounting rod 7 are slidably sleeved with rings 8, and the strip plate 9 is fixedly connected between the two rings 8. By utilizing the sliding sleeve connection between the ring 8 and the mounting rod 7, the die-cutting height of the die-cutting knife 11 can be manually adjusted, thereby realizing the die-cutting of OCA optical adhesives of different thicknesses. The inner wall of the ring 8 is annularly fixedly connected with a plurality of arc grooves 13, and the number of the arc grooves 13 is not less than ten. The interiors of the plurality of arc grooves 13 are movably sleeved with arc protrusions 12, and the arc protrusions 12 have a certain elasticity. The plurality of arc protrusions 12 are annularly equidistantly fixedly connected to one side of the mounting rod 7.
