[0041] The use process of the mobile phone protective film cutting equipment suitable for different hardness provided by the application is as follows: When the ordinary hardness protective film is cut, the power control seat 1 is started through the control panel 11, so that the protective film can pass through the cutting knife 482 after passing through the adjusting roller 21, and the cutting of the protective film can be directly completed.

[0042] When the protective film with high hardness needs to be cut, the electric telescopic rod 62 is started through the control panel 11, the electric telescopic rod 62 is started to push the sliding shaft 63 connected to the output end of the electric telescopic rod 62 to slide downward through the arc displacement slot 53, the cutting shaft 64 connected to the inside of the sliding shaft 63 is synchronously moved downward with the downward movement of the sliding shaft 63, the downward movement of the cutting shaft 64 drives the downward movement of the cutting blade 65, and the cutting blade 65 is moved downward to the position where the protective film passes through.

[0043] It should be noted that the position of the downward movement of the cutting blade 65 coincides with the cutting knife 482, so that the cut protective film will not contact the cutting knife 482.

[0044] After the cutting blade 65 position movement is completed, the second motor 66 is started to drive the cutting shaft 64 to rotate, so that the cutting blade 65 rotates to cut the protective film in contact with it.

[0045] When the cutting blade 65 rotates, the cutting shaft 64 will drive the transmission tooth belt 87 to move through the first toothed pulley 67 at one end, and the transmission tooth belt 87 will move through the upper adjusting wheel 81, the middle tensioning wheel 82, and the lower adjusting wheel 83 to drive the second toothed pulley 753 to rotate, which will drive the polishing shaft 752 to rotate. At this time, the polishing shaft 752 is elastically hinged to the knife seat support shaft 71 through the shaft end support plate 751 and the roller support shaft 75.

[0046] The polishing shaft 752 will be pressed against the surface of the protective film by the elastic force, allowing the surface of the protective film after cutting to be polished by friction.

[0047] It should be noted that when adjusting the position of the sliding shaft 63, since the middle part of the transmission tooth belt 87 is subjected to downward pressure through the middle tensioning wheel 82, when the transmission tooth belt 87 at one end is loosened or tightened, the middle tensioning wheel 82 can still exert sufficient pressure on the transmission tooth belt 87 through the elastic force of the tensioning spring 865 applied to the wheel body mounting plate 861, ensuring that the transmission tooth belt 87 is always in a tensioned state and ensuring the stability of the meshing of the transmission tooth belt 87 with the first toothed pulley 67 and the second toothed pulley 753.

[0048] It should be noted that the clockwork spring 471 used to elastically connect the hinge seat 46 on the top surface of the displacement frame device 4 to the rotating rod 47 has sufficient elastic force to enable the lower knife seat device 48 connected to the outer wall of the rotating rod 47 to drive the cutting knife 482 to always have a pushing force against the positioning support shaft 22.

[0049] The upper knife seat 72 connected to the top end of the cutting knife 482 can enable the axial attachment device 5 to have sufficient lateral support force through the internal clockwork spring 471, so that the other end of the axial attachment device 5 is always in a cantilevered state, enabling the arc-shaped attachment opening 51 to be attached to the positioning support shaft 22.

[0050] When the arc-shaped attachment opening 51 is attached to the positioning support shaft 22, since the arc-shaped attachment opening 51 has the ball 52 inside, the axial attachment device 5 will not rub against the positioning support shaft 22, ensuring the long service life of the axial attachment device 5.

[0051] The polishing device 7 is connected to the position of the upper knife seat 72, which can always provide downward pressure to the roller support shaft 75 through the second clockwork spring 471 in the spring storage slot 74, enabling the polishing shaft 752 to exert a certain pressure on the mobile phone protective film, ensuring the polishing effect.

[0052] It should be noted that: in the use of ordinary cutting knife 482, can be through the direct start second motor 66 drive cutting shaft 64 rotation, namely can drive polishing shaft 752 rotation, polishing of ordinary hardness protective film, improve the cut precision of ordinary film after cutting.

[0053] It should be noted that: in the present application, there is not only one displacement frame device 4, can according to the actual need cutting shares, using multiple displacement frame device 4 to cut protective film, at the same time in adjusting the displacement frame device 4 position, only need to directly start the drive device 45, namely can drive displacement frame device 4 sliding in displacement side of the shaft device 3, complete cutting knife 482 position movement.
