Description

Technical Field

[0001] This utility model relates to the field of high-temperature protective film technology, specifically a high-temperature protective film with double-layer thickened edges. Background Technology

[0002] High-temperature protective films are industrial materials designed for specific high-temperature environments. They mainly include PET, PE, CPP and other material types, and are used in fields such as electronic manufacturing and welding protection. When purchasing, you need to pay attention to the temperature resistance parameters and tear resistance.

[0003] For example, patent document CN 223102918 U discloses a high-temperature resistant protective film with no edge residue. It comprises a substrate layer, a high-temperature resistant barrier layer, an adhesive layer, and a release film, sequentially bonded from top to bottom. The adhesive layer consists of several sheet-like adhesive layers, which are intermittently arranged between the high-temperature resistant barrier layer and the release film. By coating the high-temperature resistant barrier layer between the substrate and the adhesive layer, it effectively prevents the release of small molecules, ensuring that the surface of the object being coated remains uncontaminated. The sheet-like adhesive layer design avoids mechanical damage to the adhesive layer by the cutting tool during die-cutting, effectively solving the problem of residual adhesive at the die-cutting edges.

[0004] However, in actual use, due to its structural limitations, this structure can only be used for simple reinforcement of the edges of the high-temperature protective film. It cannot properly perform double-layer thickening for the easily damaged edges. At the same time, the equipment cannot assist in the proper winding of the double-layer thickened high-temperature protective film, which cannot meet the needs of daily use. Therefore, it is urgent to design a high-temperature protective film with double-layer thickening at the edges to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a high-temperature protective film with double-layer thickening at the edges, in order to solve the problems mentioned in the background art. In actual use, due to the limitations of its own structure, the existing structure can only perform simple reinforcement of the edges of the high-temperature protective film, and cannot properly perform double-layer thickening for the easily damaged edges. At the same time, the equipment cannot assist in the proper winding operation of the double-layer thickened high-temperature protective film, which cannot meet the needs of daily use.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-temperature protective film with double-layer thickened edges, comprising a winding main tube, an unwinding main groove on the front side of the winding main tube, winding assemblies on both sides of the winding main tube, and a protective film assembly on the front side of the winding main tube. The winding assembly includes a tapered side seat and a winding side seat. The tapered side seats are fixedly connected to both sides of the winding main tube, and the winding side seat is fixedly connected to one end of the tapered side seat. The protective film assembly includes a main film body, which is disposed on the front side of the winding main tube.

[0007] Preferably, an extended side membrane is fixedly connected to both sides of the main membrane body, and a thickened side membrane is fixedly connected to both sides of the extended side membrane.

[0008] Preferably, the front side of the winding side seat is provided with a side unwinding groove, which is adapted to the thickened side film.

[0009] Preferably, the front of the conical side seat is provided with an unwinding groove, which is adapted to the expansion side film.

[0010] Preferably, a bearing seat is provided at the center of the side of the winding side seat, and a back cover is provided on the back of the winding main tube, the tapered side seat and the winding side seat.

[0011] Preferably, the inner wall of the unwinding main groove is provided with sealing strips on the upper and lower surfaces.

[0012] Preferably, the main winding tube, the tapered side seat, and the winding side seat are mutually adapted.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This double-layered, thickened high-temperature protective film, through its winding main tube, unwinding main groove, conical side seat, winding side seat, main film body, expanding side film, and thickened side film, enables the equipment to perform more stable high-temperature protective film edge protection operations. In actual use, the operator can pull the main film body out from inside the winding main tube and then stick it to cover the protected area. At this time, the main film body is protected by high temperature on the surface, and the two sides of the main film body can be protected by the thickened side film at both ends of the expanding side film for double-layered high-temperature edge protection. The thickened side film connects the main film body and the thickened side film to ensure overall stability, demonstrating the practicality of the equipment design.

[0014] The double-layered, thickened high-temperature protective film further enhances the overall performance of the equipment through its winding main pipe, unwinding main groove, conical side seat, winding side seat, side unwinding groove, unwinding inclined groove, bearing seat, back cover, and sealing strips. During daily use, operators can place the main film body, extended side film, and thickened side film into the winding main pipe and the conical side seats and winding side seats at both ends for positioning and fixation. The back cover secures the film, and the unwinding is controlled by the bearing seats at the center of both sides of the winding side seat. Simultaneously, when the main film body, extended side film, and thickened side film are unwound, the sealing strips on the upper and lower walls of the unwinding main groove ensure a tight seal and limit the movement, demonstrating the comprehensive design of the equipment.
