[0027] Embodiment 1

[0028] like Figure 1-3 As shown, the utility model is a high-strength conveyor belt, comprising a first wear-resistant layer 1, a first fireproof layer 2, a reinforced flame-retardant structure 3, a second fireproof layer 4 and a second wear-resistant layer 5 which are arranged in sequence from top to bottom.

[0029] The first wear-resistant layer 1 and the second wear-resistant layer 5 are both made of polyurethane.

[0030] The upper surface of the first wear-resistant layer 1 is provided with W-shaped anti-skid grooves, and the height of the W-shaped anti-skid grooves is 0.5 mm to 1 mm.

[0031] The upper surface of the second wear-resistant layer 5 is provided with an anti-skid strip 7. The anti-skid strip 7 can prevent the conveyor belt from slipping with the rotating roller. The anti-skid strip 7 is a protrusion arranged at intervals, so that there is a certain interval between the conveyor belt and the rotating roller, which plays a corresponding heat dissipation role.

[0032] The reinforced flame retardant structure 3 includes a first strong layer 301 , a supporting layer 302 , and a second strong layer 303 . The upper surface of the first strong layer 301 is connected to the first fireproof layer 2 , and the lower surface of the second strong layer 303 is connected to the second fireproof layer 4 .

[0033] The first strength layer 301 and the second strength layer 303 are both nylon canvas.

[0034] The support layer 302 is a plurality of support grids.

[0035] The upper and lower sides of the support grid are respectively provided with a first buffer layer 304 and a second buffer layer 305, which are made of rubber material. The first buffer layer 304 and the second buffer layer 305 have a certain elasticity and can effectively provide sufficient elastic buffering for the conveyor belt and buffer the conveyed objects.

[0036] The support grid is a regular hexagonal structure, and multiple support grid arrays are arranged to have a high-strength buffering effect.

[0037] The support grid is made of fluororubber and can withstand high temperatures of about 250°C. The diatom rods installed inside also have good flame retardant effects. Therefore, the support grid can achieve the triple effects of buffering, heat resistance and flame retardancy.

[0038] The first fireproof layer 2 and the second fireproof layer 4 are both made of flame-retardant rubber. While being flame-retardant, the rubber material also has a buffering effect. Therefore, the first fireproof layer 2, the second fireproof layer 4, and the reinforced flame-retardant structure 3 cooperate to play a multiple buffering and flame-retardant role, thereby enhancing the practicality of the conveyor belt.

[0039] Therefore, the utility model adopts the above-mentioned high-strength conveyor belt, which can not only enhance the toughness and impact resistance of the conveyor belt and improve its service life, but also play a good flame retardant effect and prevent the occurrence of fire.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
