Convex strips and convex blocks are distributed on the outer side of the conveyor belt, and grooves are distributed on the inner side of the conveyor belt. The conveyor belt is composed of a vulcanized rubber covering layer, a fabric core layer, a glass fiber layer, and a steel cord layer. The steel cord layer is arranged inside the glass fiber layer, the glass fiber layer is arranged inside the fabric core layer, and the fabric core layer is arranged inside the vulcanized rubber covering layer, which is convenient for being more anti-slip when conveying materials, has a high stability coefficient, reduces the risk of materials slipping out, and by setting the vulcanized rubber covering layer, fabric core layer, glass fiber layer, and steel cord layer inside the conveyor belt, the structural strength of the conveyor belt is improved, it is durable, resistant to impact and fracture, wear-resistant, corrosion-resistant, flame-retardant, anti-static, has a simple structure, has good heat preservation, high toughness, tensile strength, good flame-retardant effect, multiple functions, and a high safety factor.

[0004] The above-mentioned steel wire core flame-retardant conveyor belt is safe, anti-slip, stable and reliable, has good heat preservation, high toughness, tensile strength, good flame-retardant effect, multiple functions, and a high safety factor. However, the above-mentioned flame-retardant conveyor belt does not have a structure for optimizing the injection of edge glue. When the amount of glue added is small, the connection strength between layers is insufficient. When the amount of glue added is large, it will flow downward, and the glue content on the surface layer is still insufficient, resulting in the problem of low connection strength and poor use effect, which needs to be improved.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-6 , the present utility model provides the following technical solutions:

[0026] A steel wire rope core flame-retardant conveyor belt includes a polyurethane covering layer 1. An inner connecting device 2 is arranged inside the polyurethane covering layer 1, and an edge rubber treatment device 3 is arranged on the surface of the inner connecting device 2.

[0027] The edge glue treatment device 3 includes an arc-shaped connecting block 301, a side-end connecting plate 302, a water-sprinkling and separating injection plate 303, a bottom-end connecting plate 304, a docking block 305, and a sealing baffle 306. The arc-shaped connecting block 301 is connected to the front and rear ends of the surface of the polyurethane covering layer 1. The side-end connecting plate 302 is fixedly connected to the front of the right side of the arc-shaped connecting block 301. The side-end connecting plate 302 is fixedly connected to the back of the side-end connecting plate 302. The sealing baffle 306 is connected to the top of the uppermost water-sprinkling and separating injection plate 303. The front of the side-end connecting plate 302 is flush with the front of the wear-resistant core glue layer 201. The setting of the side-end connecting plate 302 prevents the glue from flowing out. Cooperating with the water-sprinkling and separating injection plate 303, it can make the glue stay between the inner-layer connecting device 2 and the polyurethane covering layer 1, and then solidify to form a connection. Grooves are formed inside the water-sprinkling and separating injection plate 303. The width of the grooves is adapted to the width of the docking block. The setting of the grooves facilitates the insertion of the docking block 305. The docking block 305 is inserted into the water-sprinkling and separating injection plate 303 until the bottom of the bottom-end connecting plate 304 contacts the top of the glue. Then the front of the sealing baffle 306 contacts the top end of the back of the side-end connecting plate 302 to form a seal. The docking block 305 is fixedly connected to the top of the bottom-end connecting plate 304, and the docking block 305 is inserted into the inside of the water-sprinkling and separating injection plate 303.

[0028] The inner-layer connecting device 2 includes a wear-resistant core glue layer 201, a fiberglass layer 202, and a steel cord layer 203. The wear-resistant core glue layer 201 is fixedly connected to the front and rear ends of the surface of the polyurethane covering layer 1. The steel cord layer 203 is connected to the inner circle of the fiberglass layer 202. The steel cord layer 203 and the fiberglass layer 202 have the same thickness. The fiberglass layer 202 is connected to the inner circle of the wear-resistant core glue layer 201. The fiberglass layer 202 and the wear-resistant core glue layer 201 have the same thickness. After the fiberglass layer 202, the wear-resistant core glue layer 201, and the steel cord layer 203 are bonded together, it forms an integral body, which improves the structural strength of the conveyor belt, making it durable, with functions of impact resistance, fracture resistance, wear resistance, corrosion resistance, flame retardancy, and anti-static electricity.

[0029] In use, the wear-resistant core rubber layer 201, the fiberglass layer 202, and the steel cord layer 203 are bonded together at the position of the inner layer connecting device 2 in the attached drawings of the specification, and then bonded to the front side of the polyurethane covering layer 1. At the same time, the top of the wear-resistant core rubber layer 201 is bonded to the bottom of the lowest water pouring and separating injection plate 303 and the bottom of the side end connecting plate 302. Then, glue can be injected through the groove inside the water pouring and separating injection plate 303. The glue passes through the water pouring and separating injection plate 303 and flows into the top of the wear-resistant core rubber layer 201, and then gradually seeps downward. The seepage can only reach the position where the steel cord layer 203 contacts the polyurethane covering layer 1. After it cannot seep, it starts to accumulate, filling the gap between the inner layer connecting device 2 and the polyurethane covering layer 1. Then, the glue inside starts to accumulate, gradually filling the inside of the water pouring and separating injection plate 303. The glue continuously rises until it is flush with the top of the middle layer water pouring and separating injection plate 303. Then, the docking block 305 can be aligned with the groove inside the water pouring and separating injection plate 303, and the bottom end connecting plate 304 and the docking block 305 are inserted. The docking block 305 is inserted into the water pouring and separating injection plate 303 until the bottom of the bottom end connecting plate 304 contacts the top of the glue. Then, the front side of the sealing baffle 306 contacts the top end of the back side of the side end connecting plate 302 for sealing. After sealing for a period of time, the glue solidifies, completing the process of connecting the inner layer connecting device 2 and the polyurethane covering layer 1, enabling the flame-retardant conveyor belt to be provided with a structure for optimizing side glue injection, capable of storing glue and allowing it to be between the inner layer connecting device 2 and the polyurethane covering layer 1, and then giving it time to solidify, which can ensure the connection strength, the glue content on the surface layer is sufficient, and the problem of low connection strength will not occur, and the effect during use is good.
