[0034] The protection assembly 200 is arranged on one side of the winding drum 103 and comprises an embedding groove 201, a fixing ring 202, a plug-in pipe 203, a connecting rod 204, a protective cover 205 and a fixing piece 206, the embedding groove 201 is arranged on both sides of the winding drum 103, the fixing ring 202 is fixedly connected to the inner cavity of the embedding groove 201, the plug-in pipe 203 is arranged in the inner cavity of the fixing ring 202 and penetrates through the fixing ring 202, the connecting rod 204 is fixedly connected to one side of the plug-in pipe 203, the protective cover 205 is fixedly connected to one side of the connecting rod 204, and the fixing piece 206 is arranged on one side of the plug-in pipe 203.

[0035] The antistatic property can be increased by adding antistatic agent raw materials in the aramid paper base material 101, the strength can be increased by the reinforcing layer 102, the aramid paper base material 101 and the reinforcing layer 102 can be conveniently bonded by the bonding layer, the bonding layer is a high-temperature-resistant material, has a wide range of applications, and can meet the use of aramid paper in a high-temperature environment, and the reel 103 is convenient for protecting and transporting the aramid paper.

[0036] The fixed ring 202 and the reel 103 are conveniently connected by embedding the groove 201, the fixed ring 202 has higher strength relative to the reel 103, which helps the connection of the fixing part 206, the plug-in pipe 203 is plugged into the inner cavity of the fixed ring 202, and the protective cover 205 is connected by the connecting rod 204, so that the protective cover 205 can protect the two end edges of the reel 103, thereby avoiding damage to the edges of the aramid paper during transportation or use, and the plug-in pipe 203 can be fixed by the fixing part 206, so that the protective cover 205 can stably protect the aramid paper.

[0038] The laurel fiber itself has good strength and heat resistance, but it does not have strong antistatic ability. By adding antistatic agent raw materials in the layer of laurel fiber 101a, the fiber surface has a certain conductivity, which not only reduces the accumulation of static electricity, but also quickly releases the charge when static electricity is generated, reducing the risk of static discharge.

[0042] Through the equidistant annular distribution of multiple groups of docking blocks 206b and docking grooves 206c, the equidistant distribution can avoid excessive force bearing in a single position, reduce local stress concentration, and improve the stability and service life of the entire connection structure. Through the design of multiple groups of annular distribution, each docking block 206b and docking groove 206c is involved in the connection process, and the loosening or damage of a single point due to excessive stress does not occur.

The honeycomb paperboard layer 102a can greatly enhance the compression resistance and bending resistance of the aramid paper base material 101. The silica gel layer 102b can provide additional protective and buffering performance. It can effectively reduce the damage of external impact to the structure, and has good waterproof, dustproof and corrosion resistance.

[0049] Specifically, the fixing groove 206d has multiple groups and is uniformly distributed in the inner cavity of the docking groove 206c.

[0050] The docking block 206b can be rotated into different fixing grooves 206d according to the width of the aramid paper, so as to protect aramid papers with different widths.

[0056] During transportation, the edges or surfaces of aramid paper are prone to damage, and the rubber pad 205a can provide additional protection for these vulnerable parts to reduce wear and tear.

[0057] In use, the aramid paper base material 101 contains an antistatic agent in the aramid fiber layer 101a, which can effectively prevent static electricity from accumulating and prevent static electricity from damaging the aramid paper base material 101 or other related equipment and materials. The antistatic effect is further enhanced by the antistatic layer 101b, which can prevent static electricity generated during use from negatively affecting the aramid paper. The honeycomb paperboard layer 102a can effectively disperse external pressure and impact force, reducing the direct effect of external pressure on the aramid paper base material 101. The silica gel layer 102b can provide good cushioning and shock absorption performance, effectively absorbing and dispersing external impact force during transportation or use, preventing damage to the aramid paper base material 101 caused by factors such as vibration and collision. Thus, by combining the advantages of antistatic, strength enhancement and shock protection, the aramid paper base material 101 can provide comprehensive protection during transportation, storage and use.

[0058] By inserting the insertion pipe 203 with the fixing ring 202, the connecting rod 204 drives the protective cover 205 to protect the side edges of both ends of the aramid paper, and in the insertion process, the butt block 206b enters the inner cavity of the butt joint groove 206c, improving the stability of the connection, when the butt block 206b and the fixed groove 206d are aligned, the butt block 206b can be rotated into the fixed groove 206d to limit the butt block 206b, and the magnetic attraction slot 206e-1 and the magnetic attraction block 206e-2 can further improve the stability of the connection, thereby preventing the insertion pipe 203 from loosening and falling off the fixing ring 202, and improving the stability of the aramid paper protection.
