[0014] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0015] Example like Figures 1 to 6As shown, a high-strength calendered film includes: a calendered film body 1, the calendered film body 1 including a base layer 101, a reinforcing layer 102 provided on one side of the base layer 101, a waterproof layer 103 provided on the side of the reinforcing layer 102 away from the base layer 101, an anti-corrosion layer 104 provided on the side of the waterproof layer 103 away from the reinforcing layer 102, and an antistatic agent coating 105 provided on the other side of the base layer 101. The anti-corrosion layer 104 is an epoxy anti-corrosion coating, and the antistatic agent coating 105 uses PVC-based antistatic film, PE-based antistatic film, etc. The waterproof layer 103 improves the waterproofness of the calendered film, blocking water droplets on the outside of the waterproof layer 103 and preventing water droplets from penetrating into the calendered film body 1. The reinforcing layer 102 improves the overall strength of the calendered film, preventing the calendered film from tearing easily, thus improving the performance and service life of the calendered film. The antistatic agent coating 105 inhibits and reduces the generation of static charge. The anti-corrosion layer 104 provides anti-corrosion protection for the surface of the calendered film body 1, preventing the calendered film from rotting due to prolonged use.
[0016] In this embodiment, as Figure 3 As shown, the reinforcing layer 102 includes an adhesive layer 1021, transverse reinforcing fibers 1022, and longitudinal reinforcing fibers 1023. The transverse reinforcing fibers 1022 and longitudinal reinforcing fibers 1023 are made of glass-reinforced fibers, nanocomposite fibers, etc. The transverse reinforcing fibers 1022 and longitudinal reinforcing fibers 1023 are laid on the surface of the base layer 101 through the adhesive layer 1021 in a network structure. The adhesive layer 1021 is formed of a polymer solution. The polymer solution can serve as a carrier for the transverse reinforcing fibers 1022 and longitudinal reinforcing fibers 1023, helping the transverse reinforcing fibers 1022 and longitudinal reinforcing fibers 1023 to be evenly distributed in the calendered film.
[0017] In this embodiment, the high-strength calendered film also includes a winding roller 2 and a calendered film limiting mechanism. The calendered film body 1 is wound around the outside of the winding roller 2. The calendered film limiting mechanism includes a retaining component 3 and a limiting component 4 installed on the winding roller 2. An installation cavity is provided axially at the center of the winding roller 2. The retaining component 3 is installed in the installation cavity of the winding roller 2. The retaining component 3 is used to fix the calendered film limiting mechanism to the winding roller 2. The limiting component 4 is used to align the calendered film body 1 wound on the winding roller 2. The calendered film limiting mechanism is composed of the retaining component 3 and the limiting component 4. The retaining component 3 is limited and installed inside the installation cavity of the winding roller 2, fixing the retaining component 3 to the winding roller 2. The limiting component 4 then blocks and limits the calendered film body 1 wound around the outside of the winding roller 2, ensuring the position and alignment of the calendered film during winding.
[0018] In this embodiment, as Figure 4 , Figure 5 and Figure 6As shown, the fixing assembly 3 includes a mounting post 301. The diameter of the mounting post 301 is smaller than the mounting cavity of the winding roller 2. A receiving cavity is opened on one side of the mounting post 301. A rotating disk 302 is arranged in the receiving cavity. Multiple mounting grooves communicating with the receiving cavity are equally spaced along the circumferential direction on the outer wall of the mounting post 301. A pressing block 303 is slidably connected in the mounting groove. A linkage structure is provided between the rotating disk 302 and the pressing block 303. The linkage structure is used to drive the multiple pressing blocks 303 to move synchronously when the rotating disk 302 rotates. The fixing assembly also includes a rotating structure, which is used to drive the rotating disk 302 to rotate.
[0019] The linkage structure includes a linkage column 3031 fixedly connected to one end of the abutment block 303 located inside the receiving cavity. Multiple linkage slots 3021 corresponding to the positions of the linkage column 3031 are equally spaced along the circumferential direction on the rotating disk 302. The linkage slots 3021 extend along the outer wall of the rotating disk 302 towards its center. One end of the linkage column 3031 is slidably installed in the linkage slot 3021.
[0020] The mounting post 301 has a through hole at the center of the side away from the receiving cavity. The rotating structure includes a first threaded sleeve 304 fixedly connected in the through hole. A first threaded rod 305 is threadedly connected in the first threaded sleeve 304. A guide post 306 is fixedly connected to one end of the first threaded rod 305 placed in the through hole. A guide sleeve 307 is fixedly connected to the center of the rotating disk 302. The guide post 306 slides through the guide sleeve 307. Limiting blocks 3061 are provided on both sides of the outer wall of the guide post 306. Limiting grooves for the insertion of the limiting blocks 3061 are provided on both sides of the inner wall of the guide sleeve 307. A first knob 308 is fixedly connected to the other end of the first threaded rod 305.
[0021] A stop plate 309 is fixedly connected to the outer side of the mounting column 301 away from the receiving cavity. The diameter of the stop plate 309 is larger than the diameter of the mounting cavity of the winding roller 2 and smaller than the diameter of the winding roller 2.
[0022] When installing the retaining assembly 3 to the winding roller 2, the mounting post 301 is inserted into the mounting cavity of the winding roller 2. Then, the first threaded rod 305 is rotated within the first threaded sleeve 304 by the first knob 308, thereby adjusting the position of the first threaded rod 305. The guide post 306 is fixedly connected to the first threaded rod 305, thereby synchronously adjusting the position of the guide post 306, allowing the guide post 306 to slide within the guide sleeve 307. Furthermore, the limiting block 3061 on the guide post 306 and the limiting groove on the guide sleeve 307 ensure that the guide post 306... During the sliding process of the guide sleeve 307, it plays a limiting role, so that when the first threaded rod 305 rotates, it drives the guide sleeve 307 and the rotating disk 302 to rotate synchronously, thereby adjusting the position of the linkage slot 3021 on the rotating disk 302. This causes the linkage column 3031 to adjust its position along the linkage slot 3021, thereby driving the pressing block 303 to extend synchronously to the outside of the mounting column 301. This allows the pressing block 303 to press against the inner wall of the mounting cavity of the winding roller 2, facilitating the assembly and disassembly of the calendering film limiting mechanism and the winding roller 2. This also allows the calendering film limiting mechanism to be reused, reducing costs.
[0023] In this embodiment, as Figure 4 As shown, the limiting component 4 includes a connecting plate 401 fixedly connected to the stop plate 309. A second threaded sleeve 402 is fixedly connected to one end of the connecting plate 401 away from the stop plate 308. A second threaded rod 403 is internally threaded onto the second threaded sleeve 402. A limiting plate 404 is rotatably connected to one end of the second threaded rod 403 near the winding roller 2. A second knob 405 is fixedly connected to the other end of the second threaded rod 403. An arc-shaped groove is provided at one end of the stop plate 308 near the winding roller 2. The arc-shaped groove matches the shape of the winding roller 2, and the stop plate 308 abuts against the outside of the winding roller 2 through the arc-shaped groove. The side of the stop plate 308 serves as a limiting guide to prevent the stop plate 308 from deflecting during position adjustment. By placing the stop plate 308 outside the winding roller 2, it can block and limit the calendered film body 1 wound on the outside of the winding roller 2, so as to determine the position of the calendered film body 1 during winding and ensure that the calendered film body 1 is aligned during winding. By rotating the second knob 405, the second threaded rod 403 is driven to rotate in the second threaded sleeve 402 to adjust the position of the limiting plate 404 outside the winding roller 2, so as to accurately control the winding position of the calendered film body 1 on the winding roller 2.
[0024] Implementation Scheme: In use, the mounting post 301 is inserted into the mounting cavity of the winding roller 2. Then, the first threaded rod 305 is rotated within the first threaded sleeve 304 by the first knob 308, thereby adjusting the position of the first threaded rod 305. The guide post 306 is fixedly connected to the first threaded rod 305, thereby driving the guide post 306 to adjust its position synchronously, allowing the guide post 306 to slide within the guide sleeve 307. The guide post 306 is further assisted by the limiting block 3061 on the guide post 306 and the limiting groove on the guide sleeve 307. The guide post 306 is positioned such that it acts as a limiter during the sliding process within the guide sleeve 307. This causes the first threaded rod 305 to rotate synchronously, driving the guide sleeve 307 and the rotating disk 302. This adjusts the position of the linkage slot 3021 on the rotating disk 302, causing the linkage post 3031 to adjust its position along the linkage slot 3021. This, in turn, drives the pressing block 303 to extend synchronously outward from the mounting post 301, pressing it against the inner wall of the mounting cavity of the winding roller 2. This connects the calendering film limiting mechanism with the winding roller. With the roller 2 fixed in place, the stop plate 308 is positioned on the outer wall of the winding roller 2. By rotating the second knob 405, the second threaded rod 403 rotates within the second threaded sleeve 402, adjusting the position of the limiting plate 404 on the outside of the winding roller 2. When the limiting plate 404 is adjusted to its working position, the stop plate 308 acts as a blocking and limiting element for the calendered film body 1 wound on the outside of the winding roller 2, precisely controlling the winding position of the calendered film body 1 on the winding roller 2 and ensuring the calendered film body 1 is wound... The calendered film body 1 is aligned with the waterproof layer 103, which improves the waterproofness of the calendered film and can block water droplets on the outside of the waterproof layer 103 to prevent water droplets from penetrating into the calendered film body 1. The reinforcing layer 102 improves the overall strength of the calendered film and prevents the calendered film from tearing easily, thus improving the performance and service life of the calendered film. The antistatic agent coating 105 achieves the effect of inhibiting and reducing the generation of static charge. The anti-corrosion layer 104 plays an anti-corrosion role on the surface of the calendered film body 1, preventing the calendered film from rotting due to long-term use.
