[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0028] Please see Figures 1-5This utility model provides a plastic protective film slitting device, including a base 1, which improves the stability of the device's bottom. A controller 7 is installed on the outside of the base 1, allowing operation of the electrical components within the device through the externally purchased controller 7, making operation more convenient. A first winding roller 3 and a second winding roller 5 are respectively installed on the front and rear ends of the base 1 via inserted rotating shafts 2. A first motor 4 and a second motor 6 are installed on the outside of the base 1, respectively connected to the first winding roller 3 and the second winding roller 5. This allows both the first winding roller 3 and the second winding roller 5 to rotate under the action of the first motor 4 and the second motor 6, performing the winding operation of the plastic protective film, thereby achieving slitting processing. The side of the base 1 is located at the first winding... Both roller 3 and the second take-up roller 5 have openings on their corresponding sides to facilitate the removal of the slitting plastic protective film, thus improving work efficiency. The side of the insertion shaft 2 is rotatably connected to the base 1 via a bearing, making it easy to rotate and fix the insertion shaft 2 for take-up work. A baffle 115 is provided on the inner side of the insertion shaft 2 to prevent the plastic protective film from running out during take-up. A rectangular insertion rod 116 is provided on the outer side of the baffle 115. The rectangular design provides more contact surface, making it easier to rotate and move under force. Both the first take-up roller 3 and the second take-up roller 5 have an insertion groove 117 with one side open, which connects to the insertion rod 116, thus facilitating the removal of the first take-up roller 3 and the second take-up roller 5 after take-up, thus improving work efficiency.

[0029] A pressure roller 10 is suspended at the upper end of the first take-up roller 3 to facilitate force application and improve the flatness of the winding when it is wound upwards. A hanging plate 8 is extended inwards from the upper side of the base 1 on one side of the first take-up roller 3. The rectangular hanging plate 8 is designed to bear force and support the pressure roller 10. A first scale 17 is provided on the outer side of the hanging plate 8, allowing adjustment of the position of the lower cutting blade 113 to facilitate the slitting of different sizes during winding. A connecting mounting block 9 is rotatably mounted on one side of the pressure roller 10 via a bearing, allowing the pressure roller 10 to rotate. This prevents damage to the plastic protective film during winding. The upper end of the connecting mounting block 9... The spring 13 is connected to the upper end of the base 1, allowing the pressure roller 10 to be compressed upwards, thus enabling the winding of more plastic protective film. A telescopic rod 14 is installed inside the spring 13, improving the stability of the pressure roller 10 and preventing deviation during its up-and-down movement. A side movable plate 15 is provided on the other side of the pressure roller 10, and a suspension groove 16 is provided at the upper end of the side movable plate 15, which is slidably mounted on the upper end of the suspension plate 8. This allows the side movable plate 15 to adjust the cutting blade 113 for cutting and winding during movement. A threaded hole 18 is provided at the top of the side movable plate 15, penetrating the lower suspension groove 16. A rotating bolt 19 is rotatably installed inside the threaded hole 18. The downward rotation of the rotating bolt 19, contacting the suspension plate 8, secures the side movable plate 15, improving its stability and facilitating user operation. A connecting bearing 110 is mounted at the lower end of the side movable plate 15 via a spring 13, and a telescopic rod 14 is also installed inside the spring 13 to enhance stability. A connecting layer is provided on the outer side of the connecting bearing 110 for easy connection with the spring 13 and the telescopic rod 14. The pressure roller 10 is slidably connected to the connecting bearing 110, facilitating its rotation under the action of the connecting bearing 110. The sliding connection also facilitates the adjustment of the lower cutting blade 113. A third electric motor is installed on the outer side of the extension plate at the bottom of the connecting bearing 110. The machine 111 has a transmission rod 112 connected to the output end of the third motor 111, which passes through the extension plate and is connected to the cutting blade 113. This avoids the situation where the cutting blade 113 is not very efficient in cutting the plastic protective film due to rolling. The transmission rod 112 driven by the third motor 111 drives the cutting blade 113 to rotate, resulting in a better cutting effect. A slide groove 11 is provided on one side of the base 1. A pointer 12 is provided on the outside of the connecting mounting block 9 and is slidably connected to the slide groove 11. A second scale 114 is installed on the side of the slide groove 11. This allows the pointer 12 to move when the pressure roller 10 is subjected to upward force. The thickness of the winding can be measured by the second scale 114, resulting in a better winding effect.

[0030] Working principle: In use, first connect the first motor 4, the second motor 6, and the third motor 111 to the controller 7 and connect them to an external power supply. Then, after the outer plastic protective film passes through the base 1, push the side movable plate 15 according to the width of the roll to move the lower cutting blade 113. Adjust the width of the roll according to the first scale 17. Under the action of the third motor 111, the cutting blade 113 rotates to cut the protective film. The rolled protective film is connected to the first take-up roller 3 and the second take-up roller 5 respectively. Under the action of the first motor 4 and the second motor 6, they rotate to take the film. When taking the film, the first take-up roller 3 has a certain thickness and exerts an upward squeezing force on the pressure roller 10. The pressure roller 10 squeezes the springs 13 on both sides, causing the pointer on the side to move outside the second scale 114. This allows the thickness of the rolled film to be measured, thus completing the work.
