[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Example 1

[0027] This utility model embodiment provides a flame-retardant wear-resistant cover adhesive for conveyor belts.

[0028] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 It includes two connecting rollers 1, which drive the base belt 3 to rotate. A drive shaft 2 is fixed in the middle of each of the two connecting rollers 1, which is connected to the drive mechanism. The base belt 3 is fitted around the outer ring of the two connecting rollers 1, and the base belt 3 is used for transportation. A cover rubber body 4 is provided on the outside of the base belt 3. The cover rubber body 4 is located on the outside of the base belt 3. While meeting the conveying function, it can achieve the effects of anti-sticking, wear resistance, buffering and flame retardancy by relying on the anti-stick layer 12, wear-resistant layer 13, buffer layer 14 and flame retardant layer 15. Several grooves 5 are opened on both sides of the base belt 3. A limit hole 11 is opened in the middle of each groove 5. Several connecting structures are provided in the middle of the cover rubber body 4. The connecting structure includes a connecting rod 6. Slide grooves 7 are opened at both ends of the connecting rod 6. Slide discs 8 are slidably connected to the inner walls of the two slide grooves 7. Springs 9 are fixed at the near ends of the two slide discs 8. Limit rods 10 are fixed at the far ends of the two slide discs 8.

[0029] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 It is worth noting that the outer surface of each limiting rod 10 is in contact with the inner wall of each limiting hole 11, the outer surface of each connecting rod 6 is in contact with the inner wall of the groove 5, one end of each spring 9 is fixed to one end of each sliding plate 8, the other end of each spring 9 is fixed to the inner wall of each sliding groove 7, the outer surface of each sliding plate 8 is slidably connected to the inner wall of each sliding groove 7, and the vertical cross-section of each sliding plate 8 is circular.

[0030] In use, this invention involves manually pressing the limiting rod 10 to move it. Since the limiting rod 10 is fixedly connected to the sliding plate 8, the sliding plate 8 slides under the limiting constraint of the sliding groove 7. During this process, the sliding plate 8 compresses the spring 9 fixed to it, creating space for the limiting rod 10 to retract into the sliding groove 7. At this point, the connecting rod 6 connecting the cover adhesive body 4 can be placed into the corresponding groove 5. When the limiting rod 10 is placed in the position corresponding to the limiting hole 11, the pressing force disappears, and the previously compressed spring 9 begins to release its elasticity. This elasticity is transmitted through the sliding plate 8, causing the limiting rod 10 to slide into the limiting hole 11, thereby completing the stable connection between the cover adhesive and related components. This achieves a stable connection effect, effectively preventing the cover adhesive from falling off during use, thus improving the stability of the cover adhesive.

[0031] Example 2

[0032] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 Based on Example 1, it adds non-stick, wear-resistant, cushioning, and flame-retardant functions;

[0033] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 It is worth noting that the cover adhesive body 4 includes an anti-stick layer 12, an abrasion-resistant layer 13 fixed inside the anti-stick layer 12, a buffer layer 14 fixed inside the abrasion-resistant layer 13, and a flame-retardant layer 15 fixed inside the buffer layer 14. The anti-stick layer 12 is made of silicone resin, the abrasion-resistant layer 13 is made of natural rubber, the buffer layer 14 is made of nitrile rubber sponge, and the flame-retardant layer 15 is made of chlorinated paraffin rubber.

[0034] In use, this invention features: an anti-stick layer 12 made of silicone resin, whose molecular structure contains silicon-oxygen bonds with high bond energy, giving the silicone material excellent thermal and chemical stability. Simultaneously, the organic groups outside the silicone main chain reduce the surface energy of the material, resulting in superior anti-stick properties. The wear-resistant layer 13 is made of natural rubber, which has good elasticity and can disperse stress through deformation under friction, reducing localized wear. The buffer layer 14 is made of nitrile rubber sponge, whose cell structure and elasticity can be adjusted according to specific needs, making it particularly suitable for conveying oily materials or as a buffer for conveyor belts in environments with chemical corrosion risks. The flame-retardant layer 15 is made of rubber containing chlorinated paraffin. Adding chlorinated paraffin to the rubber releases flame-retardant gases such as chlorine at high temperatures. These gases dilute the surrounding oxygen concentration, effectively preventing flame spread and achieving anti-stick, wear-resistant, buffering, and flame-retardant effects, meeting the needs of special scenarios and improving the functionality of the cover adhesive.
