[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figure 1-4 As shown, this utility model provides a technical solution:

[0025] A cutting device for producing protective film includes a base 1, a frame 2 vertically arranged in the middle of the left side of the base 1, a movable frame 3 movably arranged in the middle of the right side of the base 1, a translation mechanism between the base 1 and the movable frame 3, the translation mechanism including a motor 6, the motor 6 being arranged on the outer side of the middle of the right side of the base 1, a guide groove 7 being formed at the upper end of the middle of the right side of the base 1, a lead screw 8 being movably arranged inside the guide groove 7, the output shaft of the motor 6 being fixedly connected to the lead screw 8, a movable block 9 threadedly connected to the lead screw 8 being arranged in the middle of the bottom end of the movable frame 3, support plates 10 symmetrically arranged on both sides of the bottom end of the movable frame 3, the lower end face of the support plate 10 being slidably connected to the upper end face of the base 1, a lifting mechanism being arranged in the middle of the base 1, the lifting mechanism including electric push rods 15, several electric push rods 15 being arranged side by side in the middle of the left side of the base 1, and a bracket 16 being arranged at the output shaft end of the electric push rod 15. Material roller 4 is movably mounted on the upper end of bracket 16. Material roller 4 is movably mounted on the upper end of lifting mechanism. Rotation mechanism is provided between material roller 4 and movable frame 3. Rotation mechanism includes motor 11. Motor 11 is provided on the outer right side of the top of movable frame 3. Drive block 12 is fixedly connected to the output shaft of motor 11. Driven groove 13 matching drive block 12 is provided on the right side of material roller 4. Slot 14 is provided on the upper left side of frame 2. Rotating shaft matching slot 14 is provided on the left side of material roller 4. Servo slide module 5 is horizontally mounted on the top of frame 2. Cutting mechanism is movably mounted below servo slide module 5. Cutting mechanism includes hydraulic rod 17. Hydraulic rod 17 is movably mounted below servo slide module 5. Motor 2 18 is horizontally mounted on the output shaft end of hydraulic rod 17. Cutting wheel 19 is mounted on the output shaft of motor 2 18.

[0026] In this embodiment, the motor 6 drives the lead screw 8 to rotate, which in turn moves the movable frame 3. The drive block 12 on the movable frame 3 can be inserted into the driven groove 13 of the material roller 4, and the rotating shaft of the material roller 4 can be inserted into the slot 14 of the frame 2. This design makes the installation process of the material roller 4 simple and quick. For example, in an actual protective film production workshop, when the material roller 4 needs to be replaced, the operator can quickly complete the installation by following the above steps, reducing equipment downtime and improving production efficiency.

[0027] During the cutting process, the servo slide module 5 can drive the cutting wheel 19 to move horizontally, and the lifting and lowering of the cutting wheel 19 can be controlled by the hydraulic rod 17 before movement, thereby achieving equidistant cutting of the protective film. This function is crucial for protective film production because precise cutting lengths ensure product specification consistency. For example, in the production of mobile phone screen protectors, equidistant cutting ensures that each protective film meets standard dimensions, improving product quality.

[0028] The electric actuator 15 and the support 16 in the lifting mechanism can be adjusted according to the actual situation of the material roller 4. The height of the support 16 can be adjusted by extending or retracting the electric actuator 15 to adapt to different production needs. For example, when using a larger diameter or heavier material roller 4, the electric actuator 15 can lift the support 16 to a suitable height to ensure the stability of the material roller 4 during rotation and cutting.

[0029] Working principle: During cutting, the material roller 4, pre-wound with protective film, is placed on the bracket 16. Then, the electric actuator 15 is activated, driving the bracket 16 to lift the material roller 4. Next, the angle of the driven groove 13 on the right side of the material roller 4 is adjusted so that it corresponds to the drive block 12. Then, the motor 6 is activated, driving the lead screw 8 to rotate. The lead screw 8 drives the movable block 9 to move horizontally. The movable block 9 drives the movable frame 3 to move synchronously. When the movable frame 3 moves, it drives the drive block 12 at the output shaft end of the motor 11 to insert into the driven groove 13 and push the material roller 4. After the bracket 16 moves horizontally, the rotating shaft on the left side of the material roller 4 will insert into the slot 14 at the upper end of the frame 2, thus achieving quick installation. After the material roller 4 is fixed, motor 11 is started. Motor 11 controls the drive block 12 to rotate. Since the drive block 12 is inserted and fixed to the driven groove 13, it drives the material roller 4 to rotate on the bracket 16. Then, motor 2 is started. Motor 2 drives the cutting wheel 19 to rotate at high speed. The hydraulic rod 17 controls the cutting wheel 19 to descend and cut the protective film rolled on the material roller 4. During cutting, the servo slide module 5 can also drive the cutting wheel 19 to move horizontally so that the protective film is cut at equal distances. Before the servo slide module 5 drives the cutting wheel 19 to move horizontally, the hydraulic rod 17 is needed to control the cutting wheel 19 to rise. After the cutting wheel 19 moves at equal distances to the next position, it is controlled to descend.
