[0002] V-belt is a V-shaped belt, which is a unique conveyor belt and a mechanical device used to transmit force and transport goods. It has the advantages of easy installation, small footprint, high transmission efficiency and low noise. Since V-belts generate a lot of heat during operation, thermal expansion and contraction can easily cause cracks in V-belts. The above-mentioned rubber V-belts cannot solve the deformation problem caused by thermal expansion and contraction when in use.

[0003] In order to solve the above problems, after searching, the prior art discloses (application number: CN202221323508.1) a flame retardant and non-breakable rubber V-belt, which proposes "comprising: a V-belt body, a heat insulation layer, an outer protective layer, a wear-resistant layer and a heat dissipation strip, the V-belt body comprising a base layer, a reinforced inner core and a strip-shaped empty groove, a reinforced inner core is arranged in the center of the base layer, and a strip-shaped empty groove is arranged around the outside of the reinforced inner core; the heat insulation layer is wrapped around the outside of the base layer; the outer protective layer is wrapped around the outside of the heat insulation layer; the wear-resistant layer is V-shaped and wrapped around the bottom of the outer protective layer; the heat dissipation strips are arranged on both sides of the top of the wear-resistant layer to avoid cracks caused by thermal expansion and contraction of the V-belt body, a V-shaped wear-resistant layer is used to perform wear-resistant protection on the contact position between the V-belt and the rotating wheel, and a heat dissipation strip is arranged on the top of the wear-resistant layer, the heat generated by the friction of the wear-resistant layer is dissipated through the heat dissipation strip, and the heat generated by the friction is isolated by the heat insulation layer, thereby improving the service life of the rubber V-belt".

[0004] However, although there are heat dissipation strips for heat dissipation during use, the outside is still wrapped, and the heat dissipation effect is poor. The inside is heated during operation, which will affect the service life of the rubber V-belt. Utility Model Content

[0035] Embodiment 1:

[0036] Combined with Figures 1 to 3 This embodiment provides a flame-retardant and non-breakable rubber V-belt, including a rubber V-belt body 1 for transmitting power.

[0037] In order to improve the stability of the rubber V-belt body 1 when in use, a reinforcement structure is provided, including a compression layer 201 arranged in the center of the rubber V-belt body 1 to enhance durability.

[0038] As a preferred embodiment, the reinforcement structure also includes: a tensile layer 202, wrapped in the compression layer 201 to withstand the pressure during operation; a buffer layer 203, wrapped in the tensile layer 202 to absorb the shear force generated by the rubber V-belt body 1 when running at high speed; a cloth layer 204, wrapped in the buffer layer 203 to protect the internal tensile layer 202, the tensile layer 202, and the cloth layer 204; a tension layer 205, arranged between the cloth layer 204 and the buffer layer 203 to withstand the tensile stress of the rubber V-belt body 1 when it is bent during operation.

[0039] As a preferred embodiment, the compression layer 201 is made of natural rubber, the tensile layer 202 is made of polyurethane steel wire rope, the buffer layer 203 is made of natural rubber, the covering layer 204 is made of polyester canvas, and the tension layer 205 is made of natural rubber.

[0040] It should be noted that the compression layer 201 has excellent elasticity and compression performance, can withstand the compression force exerted on the belt during operation, and improve the overall strength and durability of the belt. The tensile layer 202 has extremely high tensile strength and wear resistance, and can withstand the huge tensile force generated by the belt during operation to prevent the belt from breaking. The buffer layer 203 can absorb the shear force generated when the belt runs at high speed, and reduce the wear and fatigue of the belt. The cloth layer 204 has excellent wear resistance and tear resistance, and can effectively protect the internal tensile layer 202, buffer layer 203 and compression layer 201. The tension layer 205 can withstand the tensile stress of the belt when it is bent during operation, and improve the flexibility and durability of the belt.

[0041] Embodiment 2:

[0042] On the basis of Example 1, in order to achieve a better heat dissipation effect of the rubber V-belt body 1 when in use, a heat dissipation structure is provided on the rubber V-belt body 1, and the heat dissipation structure includes heat dissipation holes arranged on both sides and the bottom of the rubber V-belt body 1 for heat dissipation.

[0043] As a preferred embodiment, the heat dissipation holes include: side heat dissipation holes 101 arranged on both sides of the rubber V-belt body 1 ; and outer heat dissipation holes 102 arranged on the bottom of the rubber V-belt body 1 .

[0044] As a preferred embodiment, the heat dissipation structure further includes an empty groove 103 arranged in the rubber V-belt body 1 to provide space for the reinforcement structure in the rubber V-belt body 1 to expand when it generates heat.

[0045] It should be noted that the side heat dissipation holes 101 and the outer heat dissipation holes 102 can quickly dissipate the heat generated inside the belt body to prevent the rubber V-belt body 1 from overheating and aging. The heat dissipation holes penetrate the cloth layer 204 to ensure that the heat can be smoothly transferred to the external environment.

[0046] As a preferred implementation, the side heat dissipation holes 101 and the outer heat dissipation holes 102 are arranged on the cloth layer 204 and penetrate the cloth layer 204 .

[0047] As a preferred embodiment, two groups of the slots 103 are arranged on the tensile layer 202 and located on the upper and lower sides of the compression layer 201 .

[0048] It should be noted that the empty groove 103 prevents excessive pressure inside the belt body due to thermal expansion, and further protects the integrity and durability of the belt body.

[0049] The operation steps are as follows: the rubber V-belt body 1 is used to drive and provide efficient power transmission. At the same time, the side heat dissipation holes 101 and the outer heat dissipation holes 102 can effectively dissipate heat during operation. At this time, the cloth layer 204 can still protect the internal structure. The cloth layer 204 made of polyester canvas can also play a good flame retardant role, so it can ensure that the rubber V-belt body 1 can operate at high compliance for a long time.

[0050] The above describes the utility model and its implementation methods, which is not restrictive. What is shown in the full text is only one of the implementation methods of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it, without departing from the purpose of the invention of the utility model, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the utility model.
