Technical Field

[0001] The utility model relates to the technical field of PET protective film processing, in particular to a hole-opening device for PET protective film processing. Background Art

[0002] A PET protective film processing hole punching equipment is usually designed to create holes or openings in PET film to meet specific application requirements. PET protective film is a polyester film widely used in various applications, usually used to protect the product surface from scratches, pollution, moisture and other damage. This film usually has excellent transparency, heat resistance and mechanical properties, making it an ideal choice in many industries. In order to adapt to different product needs, it is usually necessary to perform hole punching on the PET protective film to ensure its convenience for subsequent use.

[0003] After searching, the Chinese patent document with the announcement number CN220561720U discloses a hole-punching device for processing PET protective film, including an operating table and a cutter, a frame fixedly installed on the top of the operating table, a second push rod motor fixedly installed on the top surface of the operating table, and a fixed plate arranged below the second push rod motor. The technical solution of the application starts the second push rod motor to push the cutter on the fixed plate to be placed above the cutting opening, and then adjusts the position of the cutter on the disc by the servo motor, so as to punch holes for PET materials of different diameters. A hole matching the turntable is opened on the top surface of the operating table, and a plurality of cutting holes of different diameters are opened on the turntable, so that the residue of the PET material after the hole is punched can fall into the collection box below the turntable, which solves the problem of manually cleaning the PET material after the hole is punched when punching holes of different diameters, and improves work efficiency.

[0004] The beneficial effects of the above patent specification mentions that "the position of the tool on the disc is adjusted by a servo motor to make holes in PET materials of different diameters. A hole that matches the turntable is opened on the top surface of the operating table, and a plurality of cutting holes of different diameters are opened on the turntable, so that the PET material residue after the holes are opened can fall into the collection box under the turntable, which solves the problem of drilling holes of different diameters."
