Description

Technical Field

[0001] The utility model relates to the technical field of adhesive film production, in particular to a protective film leakage-proof and waste-discharging die-cutting device. Background Art

[0002] Protective film is a thin transparent film, mainly used to protect the screen of electronic devices, such as mobile phones, tablets, laptops, etc. It can prevent the screen from being scratched, impacted, contaminated by fingerprints and oil stains, effectively extending the service life of the screen. Protective film is usually made of polymer materials, with high transparency, good touch and easy installation.

[0022] In this embodiment, a strip plate 10 is provided in the middle of the bottom of the workbench 1 near the rear end, a rectangular hole is opened in the middle of the strip plate 10, a fixed block 15 is slidably connected in the rectangular hole, and the top of the fixed block 15 is fixedly connected to the bottom of the workbench 1, a sliding rod 14 is fixedly connected between the two ends of the rectangular hole, and the sliding rod 14 slides through the fixed block 15, a circular hole matching the sliding rod 14 is opened on the fixed block 15, a spring 16 is sleeved on the sliding rod 14 near the front end of the workbench 1, and a cleaning head 17 is fixedly connected to the front end of the strip plate 10.

[0023] In this embodiment, the rear end of the top of the strip plate 10 is fixedly connected to a vertical plate 11, and a special-shaped hole 12 is opened on the vertical plate 11. The special-shaped hole 12 includes a vertical hole and an inclined hole, and the bottom of the vertical hole is connected to the inclined hole. The rear end of the bending plate 6 is fixedly connected to two cross bars 13, and the other ends of the two cross bars 13 are fixedly connected to the same sliding rod, and the sliding rod is slidably connected in the special-shaped hole 12. The setting of the special-shaped hole 12 allows the strip plate 10 to move forward when the bending plate 6 descends, so that the cleaning head 17 removes the waste film at the bottom of the hole plug block 7, and places the waste film and adheres to the bottom of the hole plug block 7.

[0024] In this embodiment, a strip hole 102 is provided at the top of the workbench 1 just below the hole plug block 7, and the strip hole 102 is adapted to the hole plug block 7.

A controller is also provided inside the device, and the controller is electrically connected to the electric push rod 4 and the motor and the visual sensor 8 respectively. When working, the motor rotates to drive the raw material film to move, and the electric push rod 4 is started to extend, and the raw material film is cut by the outer frame cutter 503 and the hole cutter 504. At the same time, the sponge 502 inside the hole cutter 504 has a color coating. When cutting the die, the coating will contact the raw material film, so that the hole cutter 504 can cut at the same time. The raw material film is dyed at that place, and then the electric push rod 4 is retracted, and the motor is started to continue to rotate, so that the raw material film moves. When the colored paint detected by the visual sensor 8 reaches the strip hole 102, the motor stops, and the electric push rod 4 is started to extend, so that the outer frame cutter 503 and the outer frame cutter 503 cut again. At this time, the hole plug block 7 inserts the raw material film with paint into the strip hole 102 until the bottom. At the same time, the sliding rod of the cross bar 13 cooperates with the special-shaped hole 12 to move the strip plate 10 forward, so that the cleaning head 17 contacts the bottom of the hole plug block 7, so that the waste at the raw material film paint falls into the waste drawer 901 under the action of the cleaning head 17, and then the partition component is reset to realize the operation of the device.
