Abstract
Description
Technical Field
[0001] This utility model relates to the field of conveyor belts, and more specifically, to a flame-retardant and anti-static conveyor belt. Background Technology
[0002] Conveyor belts, also known as transport belts, are rubber and fiber / metal composite products, or plastic and fabric composite products, used in belt conveyors to carry and transport materials. Conveyor belts are widely used in industries such as cement, coking, metallurgy, chemical, and steel for short-distance and small-volume conveying applications. Conveyor belts enable continuous, high-efficiency, and large-angle transport, are easy to use and maintain, and save manpower and resources.
[0003] However, during operation, the conveyor belt is prone to static electricity due to prolonged friction and separation between the material and the conveyor belt. Ordinary conveyor belts have weak anti-static capabilities, and in special environments, the generation and accumulation of static electricity may lead to dangerous accidents, causing unnecessary losses or threatening personal safety.
[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
[0005] In view of the problems in the related technologies, this utility model proposes a flame-retardant and anti-static conveyor belt to overcome the above-mentioned technical problems existing in the existing related technologies.
[0006] Therefore, the specific technical solution adopted by this utility model is as follows:
[0007] A flame-retardant and antistatic conveyor belt includes a skeleton layer, and the surface of the skeleton layer is sequentially provided with a conductive fiber layer, a braided belt layer, a flame-retardant layer, a textured layer and an antistatic coating. The contact surfaces of the skeleton layer, the conductive fiber layer, the braided belt layer, the flame-retardant layer and the textured layer are connected by an adhesive layer, and the antistatic coating is sprayed on the surface of the textured layer.
[0008] Furthermore, to prevent the skeleton layer from falling off after long-term use, several grooves are provided on the surface of the skeleton layer near the conductive fiber layer, and the grooves are filled with connecting adhesive.
[0009] Furthermore, to enhance the conductivity and corrosion resistance of the conveyor belt, nickel-plated carbon fiber mesh is connected to the sides of the skeleton layer, conductive fiber layer, woven belt layer, flame retardant layer, textured layer, and antistatic coating.
[0010] Furthermore, in order to make the multi-layer structure more compact and stable, the skeleton layer and the flame-retardant layer are provided with several pointed rods, and several oblique protrusions are connected to the pointed rods. The flat end of the pointed rod extends from the side surface of the skeleton layer and the flame-retardant layer and passes through the nickel-plated carbon fiber mesh to connect with the positioning rod. The free end of the oblique protrusion faces the positioning rod.
[0011] Furthermore, in order to distribute the conductive fibers more evenly throughout the conveyor belt and improve the overall conductivity and durability of the conveyor belt, the conductive fiber layer is provided with twill one and twill two, which are cross-connected.
[0012] Furthermore, in order to improve the overall conductivity of the conveyor belt, conductive filler is used to fill the gaps where the twill weave 1 and twill weave 2 intersect.
[0013] Furthermore, the grooves are arranged at equal intervals along the length of the skeleton layer, and the opening direction of the grooves is perpendicular to the length of the skeleton layer.
[0014] The beneficial effects of this invention are as follows: The conductive fiber layer adopts a twill weave method, allowing each fiber to cross more other fibers, forming a diagonal texture. This allows the conductive fibers to be more evenly distributed throughout the material. The internal gaps are filled with conductive fillers (such as carbon black, metal powder, etc.), which helps to improve the overall conductivity and durability. The skeleton layer and the braided belt layer effectively prevent the conveyor belt from tearing during use, making the conveyor belt more robust and improving the overall structural strength, making it less prone to breakage. The sides are sealed with nickel-plated carbon fiber mesh, which enhances the conductivity of the conveyor belt while also increasing the mechanical strength and wear resistance of the carbon fiber mesh. The antistatic coating has a better antistatic effect, ensuring safety during transportation. The multi-layered design improves the overall structural strength of the conveyor belt, and the positioning rods and pointed rods work together to fix the multi-layered structure a second time, making the entire conveyor belt more compact and stable.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] According to an embodiment of the present invention, a flame-retardant and anti-static conveyor belt is provided.
[0025] Example 1;
[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, a flame-retardant and antistatic conveyor belt according to an embodiment of the present invention includes a skeleton layer 8, which is made of polyester canvas material. Polyester canvas has good stability and tensile strength, and also has good corrosion resistance. The surface of the skeleton layer 8 is sequentially provided with a conductive fiber layer 6, a braided belt layer 5, a flame-retardant layer 3, a textured layer 2, and an antistatic coating 1. The contact surfaces of the skeleton layer 8, conductive fiber layer 6, braided belt layer 5, flame-retardant layer 3, and textured layer 2 are connected by an adhesive layer 4. The contact surfaces between each material layer and the adhesive layer 4 are rough, which helps to make the adhesive layer 4 bond more firmly. The antistatic coating 1 is sprayed on the surface of the textured layer 2. The raised texture on the textured layer 2 increases the contact area with the object, reducing static electricity generated by the object sliding and rubbing back and forth during conveyor belt operation. The conductive fiber layer 6 has two twill weaves 12 and 13, which are cross-connected. The gaps between the cross-connections of twill weaves 12 and 13 are filled with conductive filler 14. The conductive fiber layer 6 uses a twill weave method, allowing each fiber to cross more other fibers, forming a diagonal texture. This allows the conductive fibers to be more evenly distributed throughout the material, helping to improve the overall conductivity and durability. The skeleton layer 8 and the braided belt layer 5 together effectively prevent... To prevent tearing during use, the conveyor belt is made more robust, improving its overall structural strength and reducing breakage. The sides are sealed with nickel-plated carbon fiber mesh 15, which enhances both the conductivity of the conveyor belt and the mechanical strength and wear resistance of the carbon fiber mesh. Several grooves 7 are formed on the surface of the skeleton layer 8 near the conductive fiber layer 6, filled with adhesive. The grooves 7 are evenly spaced along the length of the skeleton layer 8, and their direction is perpendicular to the length of the skeleton layer 8. This design ensures a stronger bond between the skeleton layer 8 and the conductive fiber layer 6, preventing them from separating and improving overall conductivity and structural stability. The conveyor belt is solid, with a skeleton layer 8, a conductive fiber layer 6, a braided belt layer 5, a flame retardant layer 3, a textured layer 2, and an antistatic coating 1. Nickel-plated carbon fiber mesh 15 is connected to the sides of the conveyor belt, sealing the sides and enhancing the mechanical strength, wear resistance, and corrosion resistance of the carbon fiber mesh while improving the conductivity of the conveyor belt. The flame retardant layer 3 is made of flame-retardant materials with self-extinguishing properties (such as chloroprene rubber (CR), polyvinyl chloride / polyurethane (PVC / PU) composite materials, etc.). The flame retardant layer 3 effectively prevents the flame from spreading along the conveyor belt and slows down the rate at which the flame damages the entire conveyor system, buying valuable time for fire extinguishing measures.
[0027] Example 2;
[0028] like Figure 1 and Figure 4As shown, a flame-retardant and anti-static conveyor belt according to an embodiment of the present invention includes a skeleton layer 8. The skeleton layer 8 and the flame-retardant layer 3 are internally provided with a plurality of pointed rods 10. A plurality of oblique protrusions 11 are connected to the pointed rods 10. The flat end of the pointed rod 10 extends from the side surface of the skeleton layer 8 and the flame-retardant layer 3 and passes through a nickel-plated carbon fiber mesh 15, connecting to a positioning rod 9. The free end of the oblique protrusions 11 faces the positioning rod 9. During installation, the pointed rods 10 are placed inside the skeleton layer 8 and the flame-retardant layer 3, respectively. The flat end of the pointed rod 10 is fixed by the positioning rod 9. The length of the positioning rod 9 is the height from the skeleton layer 8 to the flame-retardant layer 3. The protrusions on the pointed rods 10 are firmly embedded in the skeleton layer 8 and the flame-retardant layer 3. The connection of the positioning rod 9 reinforces the multi-layered structure inside the entire conveyor belt, preventing the conveyor belt from unraveling due to aging over long-term use.
[0029] In summary, with the help of the above-mentioned technical solution of this utility model, when in use, the skeleton layer 8, conductive fiber layer 6, braided layer, flame retardant layer 3 and textured layer 2 are sequentially bonded together with high-adhesion adhesive. After bonding, an antistatic coating 1 is evenly sprayed on the surface of the textured layer 2. Nickel-plated carbon fiber mesh 15 is pasted on the side of the conveyor belt. Then, the pointed rod 10 with protrusions is inserted into the skeleton layer 8 and the flame retardant layer 3. The flat end of the pointed rod 10 is connected and fixed to the positioning rod 9 by bolts. The assembled conveyor belt is then connected to the conveying device for use.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
