[0001] This utility model relates to the field of mobile phone screen processing technology, specifically to a cutting device for the production and processing of mobile phone screen protectors. Background Technology

[0002] Screen protectors, also known as mobile phone beautification films or mobile phone protective films, are cold-laminated films applied to mobile phone screens. They are primarily used to prevent scratches and smudges. Common materials include PP, PVC, PET, and AR. Products are categorized by function, such as anti-radiation, matte, and high-transparency. Key parameters include light transmittance, abrasion resistance, and rainbow pattern control. When purchasing, it is recommended to choose electrostatic adsorption screen protectors to avoid adhesive residue. The application process requires the use of cleaning agents, cutting tools, and heat to optimize and shape the edges.

[0003] In existing technologies, when cutting mobile phone screen protectors, a large protective film is divided into multiple smaller protective films. During this process, because the large protective films have different specifications, their positions need to be adjusted before cutting so that the cutting components can cut them. However, it is not easy to place the protective film in the center of the top of the worktable during adjustment, and slight skew is not easily detected. As a result, the protective film is not of standard size after being cut into small pieces, leading to an increased defect rate.

[0004] In view of this, a cutting device for manufacturing and processing mobile phone screen protectors is provided to overcome the above-mentioned defects. Utility Model Content

[0020] Example 1 like Figure 1-4 As shown, a cutting device for producing and processing mobile phone screen protectors according to an embodiment of the present utility model includes an operating table 1. A measuring ruler 2 is slidably connected to the top of the operating table 1. A movable frame 3 is sleeved on both ends of the measuring ruler 2. A distance measuring light 31 is installed on one side of the movable frame 3, and a limit plate 33 is rotatably connected to the other end of the movable frame 3. A transparent window 32 is opened on the top of the movable frame 3, and a connecting block 34 is fixedly connected to the bottom of the movable frame 3. Two racks 4 and a gear 41 are provided on one side of the measuring ruler 2. The two racks 4 are movably connected to the two connecting blocks 34 respectively, and both racks 4 are drivenly connected to the gear 41. A driver 411 is provided on one side of the gear 41. In this embodiment, an operating table 1 and an anti-slip layer 12 are set as a cutting table for processing mobile phone screen protectors. Two movable frames 3 are symmetrically arranged at both ends of a measuring ruler 2 to measure and limit the position of the protector placed on the operating table 1. By setting a rack 4, a gear 41, and a driver 411, the two movable frames 3 are driven simultaneously, so that they move from the center to both ends by the same distance, ensuring that the protector is always located at the top center of the operating table 1. The distance measuring light 31 and the limiting plate 33 on the movable frames 3 cooperate with each other to form a beam of light at the top of the operating table 1. Referring to the measuring ruler 2, the two sides of the placed protector are measured to observe whether its position is accurate, thereby ensuring that the cut protector is accurate. The size of the smaller protective film is more accurate. When cutting a whole piece of protective film, first place it on the top of the operating table 1. Adjust the position of the two moving frames 3 according to the size of the protective film. Start the driver 411 to drive the gear 41 to rotate. This causes the two racks 4 located above and below the gear 41 to move in opposite directions by the same distance until they reach the width of the protective film. Turn on the rangefinder 31 and rotate the limit plate 33 so that the light emitted by the rangefinder 31 shines on the limit plate 33 to form a reference line. Place the protective film according to the reference line so that its two sides are aligned with the reference line. Then, use the cutting component to divide and cut the protective film to ensure that the edges of the cut protective film are not crooked. Two vertical support plates 11 are symmetrically arranged on the top of the operating table 1. The measuring ruler 2 is fixedly connected to both ends of the measuring ruler 2. A groove 211 matching the slider 21 is opened on one side of the vertical support plate 11. By setting the vertical support plate 11 and the slider 21, the measuring ruler 2 is installed so that it can slide stably on the top of the operating table 1.

[0021] The bottom of the measuring ruler 2 is slidably connected to the top of the operating table 1, and the measuring ruler 2 is slidably connected to the vertical support plate 11 through the slider 21 and the slide groove 211; to maintain the stability of the measuring ruler 2 when it slides, and to avoid displacement, which would cause measurement deviation.

[0022] Two anti-slip layers 12 are symmetrically arranged at both ends of the top of the operating table 1. The anti-slip layers 12 are embedded in the top surface of the operating table 1, and the top surface of the anti-slip layers 12 is on the same horizontal plane as the top surface of the operating table 1. By setting two anti-slip layers 12, the friction effect between the protective film and the top of the operating table 1 is increased, thereby increasing the stability of the protective film.

[0023] One end of the driver 411 is installed inside the control panel 1, and the output end of the gear 41 is fixedly connected to the shaft of one end of the gear 41. The driver 411 drives the gear 41 to rotate, so that the two racks 4 located above and below the gear 41 simultaneously begin to move the same distance in opposite directions.

[0024] A damping shaft 331 is installed at one end of the limiting plate 33, and the limiting plate 33 is rotatably connected to one end of the moving frame 3 through the damping shaft 331. By setting the damping shaft 331, the limiting plate 33 is driven to rotate at one end of the moving frame 3, so that the protective film will not be interfered with when it is placed on the top of the operating table 1.

[0025] The distance measuring light 31 is embedded inside the movable frame 3, and the two distance measuring lights 31 are correspondingly set with the two limiting plates 33; the distance measuring lights 31 and the limiting plates 33 set on the movable frame 3 cooperate with each other to form a beam of light on the top of the operating table 1, and measure the two sides of the placed protective film with reference to the measuring ruler 2.

[0026] In summary, with the help of the above-mentioned technical solution of this utility model, when cutting a whole piece of protective film, it is first placed on the top of the operating table 1. The positions of the two moving frames 3 are adjusted according to the size of the protective film. The driver 411 is started, which drives the gear 41 to rotate. This causes the two racks 4 located above and below the gear 41 to move in opposite directions by the same distance until they reach the width of the protective film. The measuring light 31 is turned on, and the limiting plate 33 is rotated so that the light emitted by the measuring light 31 shines on the limiting plate 33 to form a reference line. The protective film is placed according to the reference line so that its two side edges are aligned with the reference line. Then, the protective film is divided and cut by the cutting component to ensure that the edges of the cut protective film are not crooked.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
