[0035] Example 1

[0036] Please refer to Figure 1-2A protective film with sheet materials on both sides of a release film, comprising a first roll 1 for clockwise discharge and a second roll 2 for counterclockwise discharge, the first roll 1 and the second roll 2 are connected to each other through a release film 3, a first protective film 4 arranged in an arithmetic sequence is arranged on the front side of the release film 3, and a second protective film 5 arranged in an arithmetic sequence is arranged on the back side of the release film 3, and the position of the second protective film 5 is mirror-symmetrical with respect to the position of the first protective film 4.

[0037] Through the above structural design, the first protective film 4 and the second protective film 5 on the back of the release film 3 are mirror images (note that they are mirror images, not rotations, and their appearance is the same as the protective film appearance on the front of the release film 3). The purpose is that when the first protective film 4 on the front of the release film 3 of the first roll 1 is used up, after the second roll 2 is installed on the rotating shaft of the machine, the posture of the second protective film 5 on the back of the release film 3 that comes out is the same as the posture of the first protective film 4 on the front of the release film 3 of the first roll 1 (the tail of the protective film comes out first, and the tear handle 10 faces upwards), so there is no need to adjust the machine again, which improves production efficiency and saves manpower;

[0038] The discharging direction of the first roll 1 is clockwise, and the receiving direction of the second roll 2 is counterclockwise. The purpose is that when the first protective film 4 on the front side of the release film 3 is used up, after the second roll 2 is installed on the rotating shaft of the machine, the second protective film 5 on the back side of the release film 3 coming out of the second roll 2 is still facing the display screen, ensuring that the directions are the same, without adjusting the machine, a release film 3 has protective films on both the front and back sides, one more than the current conventional roll, saving release film 3, reducing costs, improving production efficiency, and saving manpower.

[0039] Specifically, the upper ends of the first protective film 4 and the second protective film 5 are both provided with a camera hole 6 and an ambient light hole avoidance space 7 .

[0040] Through the above structural design, the discharging direction of the first roll 1 is clockwise, and in addition, the receiving direction of the second roll 2 is counterclockwise. The purpose is that when the first protective film 4 on the front side of the release film 3 is used up, after the second roll 2 is installed on the rotating shaft of the machine, the second protective film 5 on the back side of the release film 3 coming out of the second roll 2 is still facing the display screen, ensuring that the directions are the same, without adjusting the machine, a release film 3 has protective films on both the front and back sides, one more than the current conventional roll, saving the release film 3, reducing costs, improving production efficiency, and saving manpower.

[0041] Specifically, the relative positions of the first protective film 4 and the second protective film 5 are both in a staggered state.

[0042] Through the above structural design, the first protective film 4 and the second protective film 5 are provided with a camera hole 6 and an ambient light hole avoidance space 7. Since the hole avoidance space is formed by punching or laser, the heavy release film 3 of the hole position needs to be punched or lasered off, so in order to avoid accidentally damaging the second protective film 5 on the other side, the first protective film 4 and the second protective film 5 on the front and back sides of the release film 3 need to be staggered by a certain position.

[0043] Specifically, a half-punching line 8 is provided between the first protective film 4 and the second protective film 5 at the middle of the release film 3 .

[0044] Through the above structural design, a half punching line 8 is added in the middle of the release film 3 between the two sets of protective films. When sheet packaging rather than roll packaging is required, a single set of protective films can be torn off manually.

[0045] Specifically, an “F”-shaped mark 9 is provided on the front side of the first protective film 4 and the second protective film 5 .

[0046] Through the above structural design, a direction indicating character F is formed (it does not exist in the real object, but is only used to illustrate the direction of the protective film of the utility model).

[0047] Example 2

[0048] The protective film with sheets on both sides of the release film provided in Example 1 is further optimized. Specifically, Figure 1 As shown, a tear handle 10 is provided on one side of the first protective film 4 and the second protective film 5 .

[0052] Through the above structural design, the front and rear ends of the release film 3 between the first roll 1 and the second roll 2 are each left empty by 1000 mm, which is more conducive to the machine to unfold the first roll 1 and the second roll 2 and identify the expected.

[0053] Specifically, the diameter of the camera hole 6 is 1 mm to 2 mm.

[0054] Through the above structural design, in this embodiment, the diameter of the camera hole 6 is 1 mm, and it can also be other sizes under different requirements. The discharging direction of the first roll 1 is clockwise. In addition, the receiving direction of the second roll 2 is counterclockwise. The purpose is that when the first protective film 4 on the front side of the release film 3 is used up, after the second roll 2 is installed on the rotating shaft of the machine, the second protective film 5 on the back side of the release film 3 coming out of the second roll 2 is still facing the display screen, ensuring that the directions are the same, without adjusting the machine, a release film 3 has protective films on both the front and back sides, one more than the current conventional roll, saving the release film 3, reducing costs, improving production efficiency, and saving manpower.

[0055] Specifically, the thickness of the release film 3 is 50 um to 100 um.

[0056] Through the above structural design, in this embodiment, the thickness of the release film 3 is 50 um, and it can also be other sizes under different requirements.

[0057] Specifically, the first protective film 4 and the second protective film 5 are made of any one of PU, PVP and PI.

[0058] The protective film with sheet materials on both sides of the release film provided by the utility model has the following beneficial effects:

[0059] The discharging direction of the first roll 1 is clockwise, and the receiving direction of the second roll 2 is counterclockwise. The purpose is that when the first protective film 4 on the front side of the release film 3 is used up, after the second roll 2 is installed on the rotating shaft of the machine, the second protective film 5 on the back side of the release film 3 coming out of the second roll 2 is still facing the display screen, ensuring that the directions are the same, without adjusting the machine, a release film 3 has protective films on both the front and back sides, one more than the current conventional roll, saving release film 3, reducing costs, improving production efficiency, and saving manpower.
