According to the semi-cured composite resin magnetic film, the felt is arranged outside the film sleeve, and the felt can be fixed through the buckling effect between the rivets and the extension columns, so that when the film sleeve is wound, friction can be generated between the felt and the film sleeve, and static electricity generated during friction can effectively adsorb the felt outside the film sleeve, so that the film sleeve is prevented from being damaged, and the service life of the film sleeve is prolonged. And therefore, the curling stability can be effectively improved when the film sleeve is wound, and the film sleeve can be effectively prevented from loosening.

Description

Technical Field

[0001] This utility model relates to the field of membrane material technology, specifically to a semi-cured composite resin magnetic film. Background Art

[0002] In recent years, with the development of electronic information technology, electronic devices are moving towards intelligence, miniaturization, low power consumption and high efficiency. As a result, the demand for smaller and more efficient power systems is becoming increasingly strong.

[0003] Existing semi-cured composite resin magnetic films are often simply rolled up directly during storage, which makes the film prone to loosening during placement. This can lead to the film unrolling and attracting dust and impurities. Therefore, a semi-cured composite resin magnetic film is proposed. Utility Model Content

[0004] This utility model provides the following technical solution: a semi-cured composite resin magnetic film, including a winding drum and a magnetic film body, wherein the outer wall of the winding drum is provided with a film sleeve, the inner wall of the film sleeve is provided with an anti-splashing layer, the inner wall of the film sleeve is provided with a curing agent, the inner wall of the film sleeve is provided with a base film, the inner wall of the film sleeve is provided with an installation adhesive layer, the inner wall of the film sleeve is provided with a release film, and the outer wall of the film sleeve is provided with an anti-separation mechanism.

[0005] As a preferred embodiment of this utility model, the outer wall of the membrane sleeve is provided with an installer housing, the outer wall of the installer housing is provided with a pad, the outer wall of the pad is provided with a plurality of mounting bolts, the installer housing has an energy storage groove on the side away from the pad, the outer wall of the installer housing is provided with an extension column, the inner wall of the installer housing is provided with a trapezoidal pad, the extension column has a felt on the side away from the installer housing, and the outer wall of the felt is provided with rivets, and the rivets are symmetrically distributed on the outer wall of the felt.

[0006] As a preferred embodiment of this utility model, the membrane sleeve is mainly made of silicone material.

[0007] As a preferred embodiment of this utility model, the trapezoidal pad is slidably connected to the felt, and the rivet is fixed to the felt by a snap-fit ​​connection.

[0008] In a preferred embodiment of this invention, the mounting bolt is fixed to the housing of the installer via a threaded connection.

[0009] As a preferred embodiment of this invention, the base film is mainly made of silicon-based material.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] This semi-cured composite resin magnetic film, by setting felt on the outside of the film sleeve and fixing the felt with the snap action between the rivets and the extension column, can cause the felt to rub against the outside of the film sleeve when the film sleeve is rolled up. The static electricity generated during the friction can effectively attract the felt to the outside of the film sleeve, thereby effectively improving the stability of the film sleeve during winding and thus effectively preventing the film sleeve from loosening.
