Description

Technical Field

[0001] This application relates to the field of belt conveyors, and in particular, to an aramid cord fabric conveyor belt. Background Art

[0002] A belt conveyor is a machine that frictionally drives and continuously transports materials, mainly composed of a frame, a conveyor belt, idlers, drums, a tensioning device, a transmission device, etc. The conveyor belt is the main component for traction and carrying materials, and it not only needs to have sufficient strength but also corresponding load-bearing capacity.

[0003] An aramid conveyor belt is a conveyor belt mainly made of aramid (aromatic polyamide) fibers for material transportation, with excellent properties such as high strength, high modulus, light weight, low elongation rate, and chemical corrosion resistance.

[0004] Currently, Chinese Patent No. CN104044290A discloses an aramid conveyor belt finger joint and its preparation method. The preparation method includes steps such as stripping the cover rubber, cleaning the residual rubber, cutting the finger shape, applying glue slurry, splicing the finger shape, forming and applying rubber, applying a fabric reinforcement layer, applying the cover rubber, and sample vulcanization. When assembling the aramid conveyor belt, it is necessary to wind the strip-shaped conveyor belt surface around the conveying roller, then form a finger joint by cutting and grinding, then overlap the joints, and successively perform forming and applying rubber, applying a fabric reinforcement layer, applying the cover rubber, and sample vulcanization.

[0005] Regarding the above related technologies, the inventor believes that during the formation of the finger joint, manual cutting is required, which easily damages the original structure of the aramid conveyor belt surface and has the defect of affecting the structural strength of the conveyor belt. Summary of the Invention

[0006] In order to alleviate the problem of the decline in structural strength during the conveyor belt jointing process, this application provides an aramid cord fabric conveyor belt.

[0007] An aramid cord fabric conveyor belt provided by this application adopts the following technical solutions:

[0008] An aramid cord fabric conveyor belt includes a body part and a connecting part. The two ends of the body part in the length direction are connected together through the connecting part to form a ring structure that is connected end to end. The body part includes a first aramid fabric layer, a second aramid fabric layer, and multiple aramid cords. The multiple aramid cords are fixedly connected between the first aramid fabric layer and the second aramid fabric layer. The aramid cords include a first aramid cord and a second aramid cord. The first aramid cord and the second aramid cord are arranged alternately and spaced apart along the width direction of the first aramid fabric layer. One end of the first aramid cord in the length direction of the first aramid fabric layer protrudes between the first aramid fabric layer and the second aramid fabric layer. The other end of the second aramid cord in the length direction of the first aramid fabric layer protrudes between the first aramid fabric layer and the second aramid fabric layer. The protruding parts of the first aramid cord and the second aramid cord between the first aramid fabric layer and the second aramid fabric layer are arranged alternately. The connecting part includes a binding rope. The protruding parts of the first aramid cord and the second aramid cord between the first aramid fabric layer and the second aramid fabric layer are fixedly connected through the binding rope to form a binding layer. Cover rubber layers are arranged on both sides of the binding layer. One side of one of the cover rubber layers away from the binding layer is flush with the side of the first aramid fabric layer away from the second aramid fabric layer. The side of the other cover rubber layer away from the binding layer is flush with the side of the second aramid fabric layer away from the first aramid fabric layer.

[0009] By adopting the above technical solution, multiple aramid cords are fixedly arranged alternately between the first aramid fabric layer and the second aramid fabric layer, effectively enhancing the overall strength and stiffness of the conveyor belt; the first aramid cord and the second aramid cord are arranged alternately and spaced apart along the width direction, and protrude from the fabric layers at both ends in the length direction. When connecting the two ends of the body part, the protruding aramid cords are fixedly connected through the binding rope to form a binding layer. When the conveyor belt is stressed, the stress can be more evenly distributed on the entire structure, reducing the phenomenon of local stress concentration, and reducing the possibility of the conveyor belt breaking or being damaged due to stress concentration. By arranging cover rubber layers on both sides of the binding layer, the binding rope is more tightly connected to the first aramid cord and the second aramid cord, improving the reliability of the connecting part. At the same time, a certain degree of wear resistance and anti-corrosion protection is provided for the binding layer, making the connection of the connecting part to the body part more stable, improving the service life of the conveyor belt, and there is no need to cut during the connection process of the body part, alleviating the problem of the decrease in structural strength during the joint process of the conveyor belt.

[0010] Optionally, an adhesive layer and a reinforcing layer are arranged between the cover rubber layer and the binding layer, and the reinforcing layer is located between the adhesive layer and the cover rubber layer.

[0011] By adopting the above technical solution, an adhesive layer and a reinforcing layer are arranged between the cover rubber layer and the binding layer. The reinforcing layer is bonded to the binding layer through the adhesive layer, further improving the connection strength of the connecting part. At the same time, the reinforcing layer is used to increase the wear resistance of the connecting part and extend the service life of the conveyor belt.

[0012] Optionally, the binding rope is sequentially connected to the first aramid cord and the second aramid cord arranged alternately along the width direction of the first aramid fabric layer.

[0013] By adopting the above technical solution, the binding rope is sequentially connected to the first aramid cord and the second aramid cord arranged alternately along the width direction of the first aramid fabric layer, and the binding rope is perpendicular to the aramid cord, ensuring that each aramid cord can be firmly fixed in the conveyor belt structure, enhancing the interaction force between the first aramid cord and the second aramid cord, and significantly improving the overall connection strength of the conveyor belt; in addition, the first aramid cord and the second aramid cord arranged alternately are continuously connected by the binding rope to form a stable three-dimensional network structure. This structure not only enhances the shear resistance of the conveyor belt but also improves its stability under complex stress conditions. Even when subjected to large impacts or vibrations, the conveyor belt can maintain a good shape and performance.

[0014] Optionally, a plurality of the binding ropes are provided, and the plurality of binding ropes are arranged at intervals along the length direction of the aramid cord.

[0015] By adopting the above technical solution, a plurality of binding ropes are arranged at intervals along the length direction of the aramid cord. This connection method helps to reduce the stress concentration phenomenon caused by too strong or too weak local connection. In addition, the arrangement of a plurality of binding ropes increases the redundancy of the connection. Even if one or several of the binding ropes become loose or damaged, the other binding ropes can still maintain the effectiveness of the connection between the first aramid cord and the second aramid cord, thereby improving the overall strength and stability of the conveyor belt.

[0016] Optionally, the twisting directions of the first aramid cord and the second aramid cord are opposite.

[0017] By adopting the above technical solution, the design with opposite twisting directions can enhance the locking effect between the cords. When the binding layer is subjected to external forces, these cords with opposite twists will restrict each other, reducing the possibility of relative sliding, thereby improving the overall stability of the connection part; in addition, the aramid cords with opposite twists can better disperse the stress received by the joint. Since the twisting directions of the cords are opposite, they can absorb and disperse stress in different directions, thereby reducing the risk of local stress concentration and improving the fatigue resistance of the joint. Aramid conveyor belts are usually used in various complex working conditions, such as high-temperature, high-pressure, and high-friction environments. The aramid cords with opposite twists can better adapt to these complex working conditions and improve the stability and reliability of the connection part.

[0018] Optionally, the length of the part of the first aramid cord protruding between the first aramid fabric layer and the second aramid fabric layer is less than the distance between the two ends of the first aramid fabric layer, and the length of the part of the second aramid cord protruding between the first aramid fabric layer and the second aramid fabric layer is less than the distance between the two ends of the first aramid fabric layer.

[0019] By adopting the above technical solution, the lengths of the parts of the first aramid cord and the second aramid cord protruding between the first aramid fabric layer and the second aramid fabric layer are both less than the distance between the two ends of the first aramid fabric layer, reducing the possibility of the ends of the aramid cords being worn.

[0020] Optionally, there is a gap between adjacent first aramid cords and second aramid cords.

[0021] By adopting the above technical solution, there is a gap between adjacent first aramid cords and second aramid cords, so that while maintaining sufficient strength, the connecting part also has a certain flexibility. This flexibility enables the connecting part to better adapt to the bending and stretching requirements of the conveyor belt, reducing the risk of joint damage caused by excessive stretching or bending.

[0022] Optionally, a limiting rubber strip is connected between the first aramid cord and the second aramid cord. The limiting rubber strip is used to limit the position change between the first aramid cord and the second aramid cord. The limiting rubber strip includes a rubber strip body and a plurality of limiting grooves opened on the rubber strip body. The first aramid cord is clamped in the limiting grooves, and the second aramid cord is clamped in the limiting grooves.

[0023] By adopting the above technical solution, the position change between the first aramid cord and the second aramid cord is restricted by the limiting rubber strip, reducing the possibility of the aramid cords shifting or loosening inside the connecting part. Through the constraint of the limiting grooves, the relative movement between the aramid cords is restricted within a certain range, thereby reducing the wear caused by friction. In addition, the design of the limiting grooves makes the installation process of the aramid cords more simple and fast. The installer only needs to clamp the aramid cords into the corresponding limiting grooves to complete the fixation, without complex adjustment and fixation operations.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] By interlacing and fixing a plurality of aramid cords between the first aramid cloth layer and the second aramid cloth layer, the overall strength and rigidity of the conveyor belt are effectively enhanced. The first aramid cord and the second aramid cord are arranged at intervals in the width direction and protrude from the cloth layer at both ends in the length direction. When connecting the two ends of the main body, the protruding aramid cords are fixedly connected by binding ropes to form a binding layer. When the conveyor belt is subjected to force, the stress can be more evenly distributed on the entire structure, reducing the phenomenon of local stress concentration and the possibility of the conveyor belt being broken or damaged due to stress concentration. By arranging a covering rubber layer on both sides of the binding layer, the binding rope is more tightly connected to the first aramid cord and the second aramid cord, thereby improving the reliability of the connection part. At the same time, the binding layer is provided with certain wear resistance and anti-corrosion protection, so that the connection of the connection part to the main body is more stable, thereby improving the service life of the conveyor belt.

[0026] By arranging multiple lashing ropes at intervals in the length direction of the aramid rope, this connection method helps to reduce the stress concentration phenomenon caused by excessive or weak local connection. In addition, the arrangement of multiple lashing ropes increases the redundancy of the connection. Even if one or several lashing ropes become loose or damaged, the other lashing ropes can still maintain the effectiveness of the connection between the first aramid rope and the second aramid rope, thereby improving the overall strength and stability of the conveyor belt;

[0027] By using a limiting rubber strip to limit the position change between the first aramid cord and the second aramid cord, the possibility of the aramid cord shifting or loosening inside the connection part is reduced. Through the constraint of the limiting groove, the relative movement between the aramid cords is limited to a certain range, thereby reducing the wear caused by friction. In addition, the design of the limiting groove makes the installation process of the aramid cord simpler and faster. The installer only needs to insert the aramid cord into the corresponding limiting groove to complete the fixation without the need for complicated adjustment and fixing operations.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0037] The embodiment of the present application discloses an aramid cord fabric conveyor belt. Refer to Figure 1 and Figure 2 , an aramid cord fabric conveyor belt includes a body part 100 and a connecting part 200. The two ends of the body part 100 in the length direction are connected together through the connecting part 200 to form a closed-loop structure. The body part 100 includes a first aramid cloth layer 110, a second aramid cloth layer 120 and multiple aramid cords, and the multiple aramid cords are fixedly connected between the first aramid cloth layer 110 and the second aramid cloth layer 120. Both the first aramid cloth layer 110 and the second aramid cloth layer 120 are mainly composed of aramid fibers (D-aromatic polyamide fibers) as warp threads, and the weft threads and the binding yarns are composed of polyamide fibers (P) or polyester fibers (E) to form a canvas structure with straight warp and straight weft.

[0038] The aramid cord includes a first aramid cord 130 and a second aramid cord 140. The first aramid cord 130 and the second aramid cord 140 are arranged at staggered intervals along the width direction of the first aramid fabric layer 110. One end of the first aramid cord 130 in the length direction of the first aramid fabric layer 110 protrudes between the first aramid fabric layer 110 and the second aramid fabric layer 120. One end of the second aramid cord 140 in the length direction of the first aramid fabric layer 110 protrudes between the first aramid fabric layer 110 and the second aramid fabric layer 120. The parts of the first aramid cord 130 and the second aramid cord 140 that protrude between the first aramid fabric layer 110 and the second aramid fabric layer 120 are arranged in a staggered manner.

[0039] Referring to Figure 1 and Figure 3 , the connecting part 200 includes a binding cord 210. The parts of the first aramid cord 130 and the second aramid cord 140 that protrude between the first aramid fabric layer 110 and the second aramid fabric layer 120 are fixedly connected by the binding cord 210 to form a binding layer. Cover rubber layers 220 are arranged on both sides of the binding layer. An adhesive layer 240 and a reinforcing layer 230 are arranged between the cover rubber layer 220 and the binding layer. The reinforcing layer 230 is located between the adhesive layer 240 and the cover rubber layer 220. One side of one cover rubber layer 220 away from the binding layer is flush with one side of the first aramid fabric layer 110 away from the second aramid fabric layer 120. One side of the other cover rubber layer 220 away from the binding layer is flush with one side of the second aramid fabric layer 120 away from the first aramid fabric layer 110.

[0040] By fixedly connecting multiple aramid cords in a staggered manner between the first aramid fabric layer 110 and the second aramid fabric layer 120, the overall strength and stiffness of the conveyor belt are effectively enhanced. The first aramid cord 130 and the second aramid cord 140 are arranged at staggered intervals along the width direction and protrude from the fabric layers at both ends in the length direction. When connecting the two ends of the body part 100, the protruding aramid cords are fixedly connected by the binding cord 210 to form a binding layer. When the conveyor belt is stressed, the stress can be more evenly distributed over the entire structure, reducing the phenomenon of local stress concentration and lowering the possibility of the conveyor belt breaking or being damaged due to stress concentration. By arranging cover rubber layers 220 on both sides of the binding layer, an adhesive layer 240 and a reinforcing layer 230 are arranged between the cover rubber layer 220 and the binding layer, and the reinforcing layer 230 is bonded to the binding layer through the adhesive layer 240, making the connection between the binding cord 210 and the first aramid cord 130 and the second aramid cord 140 tighter, further improving the connection strength of the connecting part 200. At the same time, the wear resistance of the connecting part 200 is increased by using the reinforcing layer 230, extending the service life of the conveyor belt.

[0041] Referring to Figure 1 and Figure 3, the lashing ropes 210 are sequentially connected to the alternately arranged first aramid yarn ropes 130 and second aramid yarn ropes 140 along the width direction of the first aramid fabric layer 110. The lashing ropes 210 are perpendicular to the aramid yarn ropes, ensuring that each aramid yarn rope can be firmly fixed in the conveyor belt structure, enhancing the interaction force between the first aramid yarn rope 130 and the second aramid yarn rope 140, and significantly improving the overall connection strength of the conveyor belt. In addition, the alternately arranged first aramid yarn ropes 130 and second aramid yarn ropes 140 form a stable three-dimensional network structure through the continuous connection of the lashing ropes 210. This structure not only enhances the shear resistance of the conveyor belt but also improves its stability under complex stress conditions. Even when subjected to large impacts or vibrations, the conveyor belt can maintain its good shape and performance.

[0042] Refer to Figure 3 , there are multiple lashing ropes 210, and the multiple lashing ropes 210 are arranged at intervals along the length direction of the aramid yarn ropes. By arranging multiple lashing ropes 210 at intervals along the length direction of the aramid yarn ropes, this connection method helps to reduce the stress concentration phenomenon caused by too strong or too weak local connections. In addition, the arrangement of multiple lashing ropes 210 increases the redundancy of the connection. Even if one or several lashing ropes 210 become loose or damaged, the other lashing ropes 210 can still maintain the effectiveness of the connection between the first aramid yarn rope 130 and the second aramid yarn rope 140, thereby improving the overall strength and stability of the conveyor belt.

[0043] Refer to Figure 1 , the kinking directions of the first aramid yarn rope 130 and the second aramid yarn rope 140 are opposite. The design with opposite kinking directions can enhance the locking effect between the yarn ropes. When the lashing layer is subjected to external forces, these yarn ropes with opposite kinking directions will restrict each other, reducing the possibility of relative sliding, thereby improving the overall stability of the connection part 200. In addition, the aramid yarn ropes with opposite kinking directions can better disperse the stress received by the joint. Due to the opposite kinking directions of the yarn ropes, they can absorb and disperse stress in different directions, thereby reducing the risk of local stress concentration and improving the anti-fatigue performance of the joint. Aramid conveyor belts are usually used in various complex working conditions, such as high-temperature, high-pressure, and high-friction environments. The aramid yarn ropes with opposite kinking directions can better adapt to these complex working conditions and improve the stability and reliability of the connection part 200.

[0044] Refer to Figure 1 , the length of the part where the first aramid yarn rope 130 protrudes between the first aramid fabric layer 110 and the second aramid fabric layer 120 is less than the distance between the two ends of the first aramid fabric layer 110, and the length of the part where the second aramid yarn rope 140 protrudes between the first aramid fabric layer 110 and the second aramid fabric layer 120 is less than the distance between the two ends of the first aramid fabric layer 110.

[0045] Refer toFigure 3 and Figure 4 , there is a gap between the adjacent first aramid cord 130 and second aramid cord 140, so that while maintaining sufficient strength, the connecting part 200 also has a certain flexibility. This flexibility enables the connecting part 200 to better adapt to the bending and stretching requirements of the conveyor belt, reducing the risk of joint damage caused by excessive stretching or bending.

[0046] A limiting rubber strip 250 is connected between the first aramid cord 130 and the second aramid cord 140. The limiting rubber strip 250 is used to limit the position change between the first aramid cord 130 and the second aramid cord 140. The limiting rubber strip 250 includes a rubber strip body 251 and a plurality of limiting grooves 252 formed in the rubber strip body 251. The first aramid cord 130 is clamped in the limiting grooves 252, and the second aramid cord 140 is also clamped in the limiting grooves 252.

[0047] By using the limiting rubber strip 250 to limit the position change between the first aramid cord 130 and the second aramid cord 140, the possibility of the aramid cord shifting or loosening inside the connecting part 200 is reduced. Through the constraint of the limiting grooves 252, the relative movement between the aramid cords is restricted within a certain range, thereby reducing the wear caused by friction. In addition, the design of the limiting grooves 252 makes the installation process of the aramid cord simpler and faster. The installer only needs to snap the aramid cord into the corresponding limiting grooves 252 to complete the fixation, without the need for complex adjustment and fixation operations.

[0048] What is not described in this application can be achieved by adopting or referring to the existing technology.

[0049] Each embodiment in this specification is described in a progressive manner. The same or similar parts between the embodiments can be referred to each other. Each embodiment focuses on the differences from other embodiments.

[0050] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
