Description

Technical Field

[0001] This application relates to the technical field of protective films, and specifically provides a scratch-resistant and easy-to-seal protective film. Background Art

[0002] Protective films can be classified into digital product protective films, automotive protective films, household protective films, food preservation protective films, etc. according to their uses.

[0003] The existing patent (publication number: CN220537134U) discloses a scratch-resistant protective film, belonging to the technical field of protective films. This scratch-resistant protective film includes a housing and a scratch-resistant protective film body. Shell covers are respectively provided at both ends of the outer wall of the housing. The adjacent sides of the two shell covers are respectively rotatably connected to the two ends of the scratch-resistant protective film body. An out-film box is provided on one side of the housing. A cutting mechanism is provided at the top of the out-film box. The cutting mechanism includes a slider, a dial, an elastic telescopic rod, a frame, a pin shaft, and a circular cutter. The bottom end of the slider is installed with an elastic telescopic rod. The top end of the elastic telescopic rod is connected to the frame. One side of the frame is inserted with a pin shaft. The frame is rotatably connected to one side of the circular cutter through the pin shaft. And the bottom end of the circular cutter penetrates through the bottom of the frame and extends to the outside. The out-film box includes a box body, a hollow groove, a sponge brush, a rounded corner, a support, and a cutting groove. A hollow groove is provided at the top of the box body.

[0004] During the use of the above protective film, through the mutual cooperation of the out-film box and the cutting mechanism, the scratch-resistant protective film is more convenient to cut during cutting and has a more flush cutting function, wherein by pushing and pulling the dial, the dial drives the slider to move stably back and forth inside the hollow groove, and then through the elastic action of the elastic telescopic rod on the frame, the circular cutter at the bottom end inside the frame is kept in contact with the film body, and through the insertion connection of the pin shaft, the circular cutter can rotate, so as to facilitate cutting the outer wall of the film body, and through the supporting action of the support, the cutting groove at its top is convenient for holding the circular cutter, which is beneficial to quickly cut the scratch-resistant protective film body and effectively improves the flatness of the cutting surface. However, during the cutting process, since the circular cutter needs to move, it may drive the film to move and shift under the shearing force during the movement, and it is easy to cause defects at the cutting position. For double-layer protective films, it is more inconvenient to use after cutting, lacking a sealing mechanism for it, and the applicability is poor. Summary of the Utility Model

A film body 6 is fixedly connected to the outer surface of the film roller 5, and the outer surface of the film body 6 is wound around the film roller 5.

[0036] Please refer to Figure 1 , Figure 2 and Figure 3 , One side surface of each of the two support seats 2 is fixedly connected with a support frame 7. An anti-scratch roller 8 is rotatably connected between the front and rear inner side walls of the support frame 7. An anti-offset component 9 is arranged above the anti-scratch roller 8.

[0037] Please refer to Figure 1 , Figure 2 and Figure 3 , The anti-offset component 9 includes a pressure roller 901, two plug plates 902, two limiting plates 903 and two springs 904. The two limiting plates 903 are respectively fixedly connected to the front and rear surfaces of the support frame 7. The two plug plates 902 are respectively slidably inserted into the limiting plates 903 closest to them. The front and rear ends of the pressure roller 901 are respectively rotatably connected to the tops of the plug plates 902 closest to them. The bottom ends of the two springs 904 are respectively fixedly connected to the bottom ends of the plug plates 902 closest to them. The top ends of the two springs 904 are respectively fixedly connected to the bottoms of the limiting plates 903 closest to them. Through the setting of the springs 904, the purpose of close contact between the pressure roller 901 and the anti-scratch roller 8 can be achieved. Through the setting of the pressure roller 901 and the anti-scratch roller 8, the purpose of limiting the film body 6 can be achieved, and at the same time, the friction coefficient between it and the support frame 7 can be reduced to achieve the anti-scratch effect.

[0038] Please refer to Figure 1 , Figure 2 and Figure 4, above the support frame 7, there is a cutting and sealing component 10. The cutting and sealing component 10 includes a U-shaped frame 101, a T-shaped rod 102, a compression spring 103, a cutting knife 104, and a heater 105. The U-shaped frame 101 is fixedly connected to the upper surface of the support frame 7. The T-shaped rod 102 is slidably inserted into the upper surface of the U-shaped frame 101. The two ends of the compression spring 103 are respectively fixedly connected to the top end of the T-shaped rod 102 and the upper surface of the U-shaped frame 101. The cutting knife 104 is fixedly connected to the bottom end of the T-shaped rod 102. The heater 105 is installed on the outer surface of the cutting knife 104. Through the setting of the cutting knife 104, the purpose of cutting the film body 6 can be achieved. Through the setting of the heater 105, during the cutting process, the cutting part can be heated to achieve the effect of sealing.

[0039] Please refer to Figure 1 , Figure 2 and Figure 4 , a cutting groove 13 is formed on the upper surface of the U-shaped frame 101. Through the setting of the cutting groove 13, the cutting knife 104 can be fitted. The bottom end of the support frame 7 is triangular.

The outer surfaces of the anti-scratch roller 8 and the pressing roller 901 are both smooth surfaces. Through the above settings, the overall anti-scratch effect can be further improved.

[0040] In a kind of anti-scratch and easy-sealing protective film in this embodiment, by setting the anti-scratch roller 8 and the pressing roller 901, and both of their surfaces are smooth surfaces, the friction coefficient during the transmission of the film body 6 is effectively reduced, scratches on the surface of the film body 6 are avoided, and the protective performance of the protective film is improved. The design of the anti-offset component 9, especially the close contact between the pressing roller 901 and the anti-scratch roller 8, ensures the stability of the film body 6 during transmission, and avoids problems such as uneven cutting or loose sealing caused by the offset of the film body 6 during cutting or sealing. The heater 105 enables the film body 6 to be heat-pressed and sealed while being cut, and also ensures the tightness and aesthetics of the seal. Through the setting of the connection hole 11, the replacement of the film roller 5 becomes simple and fast. The motor 12 drives the power shaft 3 to rotate, without manual operation, reducing the labor intensity.

[0041] The working principle of the above embodiment is as follows: The motor 12 starts, drives the power shaft 3 to rotate, and then drives the connecting disc 4 and the film roller 5 to rotate, so that the film body 6 is smoothly unfolded from the film roller 5 and transported forward. During the transportation of the film body 6, it passes between the anti-scratch roller 8 and the pressure roller 901. The two are in close contact and have a smooth surface, effectively reducing the friction between the film body 6 and the equipment and preventing the film body 6 from being scratched. As the film body 6 continues to be transported, the pressure roller 901 in the anti-offset assembly 9 always maintains close contact with the anti-scratch roller 8 under the action of the spring 904, ensuring the stability of the film body 6 on the transportation path and avoiding offset during cutting or sealing. When the film body 6 is transported to the cutting and sealing assembly 10, by pressing the T-shaped rod 102 down, the cutting knife 104 moves down with the T-shaped rod 102 to precisely cut the film body 6. At the same time, the heater 105 on the surface of the cutting knife 104 quickly heats the cutting edge to achieve hot-press sealing, ensuring the tightness and aesthetics of the seal.
