Conveyor belts, also known as transport belts, are rubber, fiber, metal composite products, or plastic and fabric composite products used to carry and transport materials during transportation. Conveyor belts are safe to operate, easy to use, and can operate continuously and efficiently.

[0003] The Chinese patent announcement number is: CN214242461U discloses a PVC type flame retardant conveyor belt, including a conveyor belt body, the conveyor belt body includes a PVC base layer, and a first flame retardant layer is arranged on the top of the PVC base layer, and at the same time, the first flame retardant layer includes an aluminum oxide coating, a phenolic resin layer and a fluororubber layer, and a second flame retardant layer is arranged on the bottom of the PVC base layer, and the second flame retardant layer includes a polytetrafluoroethylene fiber layer, a silicone rubber layer and a glass fiber layer. The utility model is provided with a first flame retardant layer including an aluminum oxide coating, a phenolic resin layer and a fluororubber layer, which can provide three-layer flame retardant protection for the top of the conveyor belt, and a second flame retardant layer including a polytetrafluoroethylene fiber layer, a silicone rubber layer and a glass fiber layer is provided, which can provide three-layer flame retardant protection for the bottom of the conveyor belt.

[0030] Embodiment 1

[0031] like Figure 1-Figure 3As shown, this embodiment provides a new type of heat-insulating and flame-retardant fabric conveyor belt, including a conveyor belt body 1, a plurality of anti-skid protrusions 2 are arranged on the top of the conveyor belt body 1, a covering layer 3 is arranged on the top of the conveyor belt body 1, a first fiber layer 4 is arranged inside the conveyor belt body 1, and a second fiber layer 5 is fixedly connected to the bottom end of the first fiber layer 4, the anti-skid protrusions 2 are coated on the top surface of the conveyor belt body 1, and the covering layer 3, the first fiber layer 4, and the second fiber layer 5 are tightly connected to increase the fireproof and heat-insulating capabilities of the conveyor belt.

[0032] The bottom end of the second fiber layer 5 is fixedly connected to the wire core layer PVG2500S fabric whole core layer 6, the middle part of the PVG2500S fabric whole core layer 6 is fixedly connected to the telescopic layer 7, the upper and lower sides of the second fiber layer 5 are fixedly connected to the toughness components, the PVG2500S fabric whole core layer 6, the telescopic layer 7, and the toughness components cooperate to increase the elasticity of the conveyor belt, the bottom end of the PVG2500S fabric whole core layer 6 is fixedly connected to the lining layer 10, the bottom end of the conveyor belt body 1 is provided with a plurality of first wave patterns 11, and the bottom end of the conveyor belt body 1 is provided with a plurality of second wave patterns 12, which effectively increase the wear resistance of the bottom of the conveyor belt.

[0033] Embodiment 2

[0034] like Figure 2 As shown, the components identical or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The second embodiment is different from the first embodiment in that: the toughness component includes two porous connecting belts with porous corrugated layers 8 and multiple inner core moisture-proof layers 9. The outer part of the porous corrugated layer 8 is fixedly connected to the upper and lower sides of the inner part of the PVG2500S fabric core layer 6. The porous corrugated layer 8 and the inner core moisture-proof layer 9 are tightly connected. The inner core moisture-proof layer 9 is arranged inside the porous corrugated layer 8. The anti-slip bump 2 is a heat-insulating raised pattern. The raised pattern with air isolation effect can effectively reduce the heat conduction between the conveyor belt and the conveyed material, thereby improving the heat insulation performance of the conveyor belt. Such raised pattern usually forms a heat-insulating layer to slow down the heat transfer speed and protect the conveyor belt from high temperature.

[0035] The covering layer 3 is a silicone rubber coating, which has excellent high temperature resistance and heat insulation properties, can effectively resist heat radiation and conduction under high temperature, and improve the heat resistance of the conveyor belt. The first fiber layer 4 is made of carbon fiber. Carbon fiber has extremely high heat resistance and mechanical strength, and is suitable for applications in high temperature environments. Adding a carbon fiber layer to the conveyor belt can improve its heat resistance and flame retardant properties. The second fiber layer 5 is made of ceramic fiber. Ceramic fiber has excellent heat insulation properties. When used in combination with carbon fiber, it can improve the heat insulation effect of the conveyor belt in a high temperature environment.

[0036] A certain amount of carbon fiber material is arranged in the PVG2500S fabric core layer 6. The carbon fiber has extremely high strength and rigidity as well as lightweight characteristics, which not only enhances the hardness and strength of the conveyor belt, but also maintains a certain degree of elasticity and flexibility, so that the conveyor belt can adapt to different working conditions and environments during operation, reduce vibration and noise, and improve transportation efficiency. The telescopic layer 7 is made of recycled rubber, which is a material recycled from waste rubber products. It has good toughness and elasticity, and is environmentally friendly, and can effectively reduce the consumption of natural resources.

[0037] The cushioning layer 10 is made of polyester fiber. Polyester fiber has good toughness and wear resistance, and is suitable for making the cushioning layer of the conveyor belt. It also has good environmental performance because it can be recycled and reused. The cushioning layer 10 and the expansion layer 7 double increase the bending resistance of the conveyor belt. The inner core moisture-proof layer 9 is made of polyethylene film. Polyethylene has good waterproof and chemical stability and is suitable for use under various environmental conditions. The porous corrugated layer 8 is made of polyurethane. Polyurethane material has good elasticity and wear resistance and is suitable for connecting the middle layer of the conveyor belt. Polyurethane material can form a strong connection and has a certain air permeability, allowing air to flow freely.

[0038] Embodiment 3

[0039] like Figure 3 As shown, this embodiment provides a new type of heat-insulating and flame-retardant fabric conveyor belt. The outside of the first wave pattern 11 is in contact with the outside of the second wave pattern 12. The first wave pattern 11 and the second wave pattern 12 are made of aramid fiber. Aramid fiber is a high-strength, wear-resistant synthetic fiber with excellent heat resistance and chemical resistance. It is suitable for use in high temperature environments and has good bending resistance, which increases the wear resistance and bending resistance of the conveyor belt.

[0040] Working steps

[0041] Step 1. During specific use, the top covering layer 3, the first fiber layer 4, the second fiber layer 5 and the bottom cushioning layer 10 are connected through the porous corrugated layer 8 and the PVG2500S fabric core layer 6, and the holes arranged on the porous corrugated layer 8 allow the porous corrugated layer 8 to allow the moisture received by the conveyor belt to be sent to the position of the inner core moisture-proof layer 9 inside the porous corrugated layer 8. The polyethylene film material of the inner core moisture-proof layer 9 absorbs the moisture and slowly dissipates it to moisturize each layer in the conveyor belt body 1, thereby preventing the conveyor belt from drying out and cracking in a dry environment. In addition, since the anti-slip bumps 2, the covering layer 3 and the first fiber layer 4 have good fire resistance, the heat insulation and flame retardant capabilities of the conveyor belt can be improved.

[0042] Step 2: When the conveyor belt is conveying items, the heat-insulating raised pattern of the anti-skid bump 2 provided on the top of the conveyor belt body 1 increases the friction with the items and the heat-insulating capacity of the conveyor belt. When the inner side of the conveyor belt contacts the roller or other items, the first wave pattern 11 and the second wave pattern 12 cross at the bottom of the conveyor belt body 1 to form a forging pattern structure, which effectively increases the toughness and wear resistance of the conveyor belt. The telescopic layer 7 is made of recycled rubber, which further increases the overall toughness of the conveyor belt.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
