Description

Technical Field

[0001] This application relates to the technical field of aramid conveyor belt connection, and in particular to an aramid conveyor belt with a quick connector. Background Art

[0002] At present, an aramid conveyor belt is a conveyor belt mainly made of aramid (aromatic polyamide) fibers and is used for material conveying, with excellent properties such as high strength, high modulus, light weight, low elongation, and chemical corrosion resistance.

[0003] Chinese Patent with publication number CN104044290A discloses an aramid conveyor belt finger joint and its preparation method. The preparation method includes steps such as stripping of the cover rubber, cleaning of the residual rubber, cutting of the finger shape, coating of the rubber solution, splicing of the finger shape, forming and pasting of the rubber, pasting of the fabric reinforcement layer, pasting of 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 conveyor roller, and then form a finger joint by cutting and grinding. Then, the finger joints of the two joints are arranged staggeredly, and then the forming and pasting of the rubber, pasting of the fabric reinforcement layer, pasting of the cover rubber, and sample vulcanization are carried out in sequence to complete the lap joint of the joints. However, for the formation of the finger joint, manual cutting is required, which easily damages the original structure of the aramid conveyor belt surface, and the efficiency of manual cutting is poor. Utility Model Content

[0004] In order to improve the connection efficiency of the aramid conveyor belt, this application provides an aramid conveyor belt with a quick connector.

[0005] An aramid conveyor belt with a quick connector provided by this application adopts the following technical solutions:

[0006] An aramid conveyor belt with a quick connector includes: a conveyor belt surface, two layers of rubber pasting layers, two layers of reinforcement layers, two layers of cover rubber layers, multiple first aramid cord ropes, and multiple second aramid cord ropes. The conveyor belt surface is in a long strip shape, and first joints and second joints are respectively formed at both ends; multiple first aramid cord ropes are buried in the conveyor belt surface and extend out from the first joints, and the multiple first aramid cord ropes are arranged along the width direction of the first joints; multiple second aramid cord ropes are buried in the conveyor belt surface and extend out from the second joints, and the multiple second aramid cord ropes are arranged along the width direction of the second joints; the multiple first aramid cord ropes and the multiple second aramid cord ropes correspond one by one and are arranged at intervals; along the middle of the first aramid cord ropes towards the direction close to both sides of the conveyor belt surface, the rubber pasting layer, the reinforcement layer, and the cover rubber layer are sequentially arranged.

[0007] By adopting the above technical solution, first prepare all necessary installation tools and materials, check the quality of the first joint and the second joint to ensure the integrity of the aramid ropes, sort out the first aramid rope and the second aramid rope, clean the surface of the joints, remove any impurities that may affect the bonding effect, and grind out a slope; apply or paste an adhesive layer on one side of the first joint, then lay the first aramid rope on the first joint in sequence on the adhesive layer, then lay the second aramid rope on the second joint on the adhesive layer, and make the first aramid rope and the second aramid rope arranged at intervals, and then arrange the adhesive layer on the other side. This step requires ensuring that the glue or adhesive is evenly covered without bubbles or missed coating. Wait for the glue or adhesive to reach the appropriate curing degree, usually determine the waiting time according to the product manual, and then lay the reinforcing layer and the cover rubber layer in sequence.

[0008] Stagger the aramid ropes of the second joint with those of the first joint. This step requires precise operation to ensure the correct staggering relationship between the ropes to improve the strength and stability of the joint; the function of the reinforcing layer is to increase the overall strength and wear resistance of the joint; the cover rubber layer not only protects the internal structure from damage by the external environment, but also improves the wear resistance and corrosion resistance of the joint.

[0009] The staggered arrangement of the aramid ropes and the superposition of multiple layers (adhesive layer, reinforcing layer, cover rubber layer) make the joint have extremely high strength and stability. This structure can effectively resist external forces such as tension and tearing, and extend the service life of the conveyor belt.

[0010] The design of this quick joint makes the installation process simpler and faster, reducing the maintenance cost and time cost; at the same time, the connection strength of the aramid ropes is high, which can shorten the length of the joint. At the same time, by reserving the aramid ropes, the damage to the original structure of the conveyor belt surface can be reduced.

[0011] The existence of the cover rubber layer makes the joint have excellent wear resistance and corrosion resistance, which can protect the internal structure from damage by the external environment and further extend the service life of the conveyor belt.

[0012] The joint design with high strength and stability reduces the risk of failure during the use of the conveyor belt and improves the safety of production operations. At the same time, the protection of the multi-layer structure also reduces the accidental shutdown caused by joint damage.

[0013] The first aramid rope and the second aramid rope are reserved and buried, formed during the processing of the conveyor belt surface, and conform to the laying direction of the aramid ropes of the aramid conveyor belt, reducing the cutting of the conveyor belt surface, reducing the damage to its original structure, thereby extending the service life of the aramid conveyor belt, and reducing the complexity of the connection of the conveyor belt surface, facilitating quick connection and improving efficiency.

[0014] Optionally, multiple said first aramid ropes are arranged with staggered lengths.

[0015] By adopting the above technical solution, through the staggered arrangement, the distribution of the first aramid ropes with staggered lengths can form a more complex stress dispersion network. When the joint is subjected to external forces, these ropes with different lengths can work together to better disperse and resist stresses such as tensile force and shear force, thereby enhancing the overall structural strength of the joint.

[0016] Optionally, multiple said second aramid ropes are arranged with staggered lengths.

[0017] By adopting the above technical solution, through the staggered arrangement, the distribution of the second aramid ropes with staggered lengths can form a more complex stress dispersion network. When the joint is subjected to external forces, these ropes with different lengths can work together to better disperse and resist stresses such as tensile force and shear force, thereby enhancing the overall structural strength of the joint; the first aramid ropes and the second aramid ropes are arranged in cooperation to form a stress network, increasing the strength at the joint.

[0018] Optionally, the twisting directions of the first aramid ropes and the second aramid ropes are opposite.

[0019] By adopting the above technical solution, the design with opposite twisting directions can enhance the locking effect between the ropes. When the joint is subjected to external forces, these ropes with reverse twists will restrict each other, reducing the possibility of relative sliding, thereby improving the overall stability of the joint; the aramid ropes with reverse twists can better disperse the stresses received by the joint. Since the twisting directions of the ropes are opposite, they can absorb and disperse stresses in different directions, thereby reducing the risk of local stress concentration and improving the anti-fatigue performance of the joint. This design can also improve the durability of the joint. The aramid ropes with reverse twists can better maintain the stability of their structures and performances during long-term use, reducing the problems of joint failure caused by wear, aging, etc.

[0020] Aramid conveyor belts are usually used in various complex working conditions, such as high-temperature, high-pressure, and high-friction environments. The aramid ropes with reverse twists can better adapt to these complex working conditions and maintain the stability and reliability of the joint.

[0021] Optionally, the length difference between two adjacent said first aramid ropes is 50 mm.

[0022] By adopting the above technical solution, through a reasonable length difference design, when the joint is subjected to external forces, the interaction between each rope can be more coordinated. This coordinated effect can enhance the overall strength and durability of the joint, reducing the problems of joint failure caused by stress concentration or fatigue damage.

[0023] Optionally, there is a gap between the adjacent first aramid cord and the second aramid cord, and an adhesive layer is formed.

[0024] By adopting the above technical solution, the appropriate gap and adhesive layer design can enable the joint to have a certain flexibility while maintaining sufficient strength. This flexibility allows the joint 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.

[0025] The presence of the adhesive layer can simplify the installation and maintenance process of the joint. During installation, the adhesive layer can provide certain positioning and fixing functions, enabling the cords to be more easily arranged and fixed according to the design requirements. During maintenance, if the joint needs to be inspected or repaired, the adhesive layer can also provide certain convenience and operability.

[0026] Optionally, there is a spacing distance between the end of the first aramid cord away from the first joint and the second joint.

[0027] By adopting the above technical solution, the design of the spacing distance reduces the direct contact and interaction between the first aramid cord and the second joint, reducing the impact on the joint performance caused by factors such as friction, wear, or corrosion.

[0028] By reasonably setting the spacing distance, the layout of the entire joint can be made more reasonable and balanced. This helps to improve the overall stability and reliability of the joint, ensuring the smoothness and safety of the conveyor belt during operation.

[0029] Optionally, the spacing distance between the end of the first aramid cord away from the first joint and the second joint is 100mm - 150mm.

[0030] By adopting the above technical solution, within this spacing distance range, sufficient space is maintained between the end of the first aramid cord and the second joint, avoiding the stress concentration phenomenon caused by direct contact. This helps to extend the service life of the cord and the joint, reducing the risk of fracture or damage caused by stress concentration.

[0031] During the joint installation process, this spacing distance design provides sufficient operating space for installers, enabling them to more easily connect and fix the cord to the joint. This helps to improve the installation efficiency and accuracy.

[0032] Optionally, a plurality of limiting rubber strips are pasted on the adhesive layer, a plurality of limiting grooves are provided on the limiting rubber strips, the first aramid cord is clamped in the limiting grooves, and the second aramid cord is clamped in the limiting grooves.

[0033] By adopting the above technical solution, the design of the limiting groove enables the first aramid cord and the second aramid cord to be accurately clamped at the specified position, thus avoiding the displacement or loosening of the cords inside the joint. This fixing method helps to improve the overall stability of the joint and ensure that the cords can maintain their predetermined arrangement and layout during the operation of the conveyor belt.

[0034] Constrained by the limiting groove, the relative movement between the cords is restricted within a certain range, thereby reducing the wear caused by friction. This not only extends the service life of the cords but also reduces the risk of joint failure caused by wear.

[0035] The design of the limiting rubber strip and the limiting groove helps to disperse the stress received by the joint. When the conveyor belt is subjected to external forces, these structures can guide the stress to be more evenly distributed inside the joint, thereby reducing the risk of local stress concentration.

[0036] By fixing the cord position and optimizing the stress distribution, this design can also enhance the load-bearing capacity of the joint. It enables the joint to better withstand stresses such as tensile force and shear force from the conveyor belt, ensuring the smoothness and safety of the conveyor belt during operation.

[0037] The design of the limiting groove makes the installation process of the cords simpler and faster. The installer only needs to snap the cords into the corresponding limiting grooves to complete the fixation, without the need for complex adjustment and fixation operations.

[0038] During maintenance, the maintenance personnel can more easily check the connection between the cords and the limiting grooves. They can judge the performance and service life of the joint by observing indicators such as the wear degree of the limiting grooves and the fixation state of the cords, and thus perform maintenance and replacement in a timely manner.

[0039] The design of the limiting rubber strip and the limiting groove enables the joint to adapt to the usage requirements under different working conditions. Whether in harsh environments such as high temperature, high humidity, and high wear, or in working conditions that require frequent bending and stretching, this design can ensure the stability and reliability of the joint.

[0040] If it is necessary to adjust the layout of the joint or the arrangement of the cords, it can be achieved by simply loosening the cords in the limiting grooves and re-snapping them. This flexible adjustment method makes the joint more adaptable to the requirements of different conveyor belts and working conditions.

[0041] Optionally, a friction portion is formed in the limiting groove, and an overflow hole is provided at the bonding position of the limiting rubber strip and the rubberized layer, and the overflow hole communicates with the limiting groove.

[0042] By adopting the above technical solution, the design of the friction part in the limiting groove increases the contact area and friction force between the wire rope and the limiting groove. When the wire rope is clamped in the limiting groove, the friction part can provide better grasping force, preventing the wire rope from slipping or falling off during the force application process, thereby improving the connection strength and stability of the joint.

[0043] Through the design of the glue overflow hole, the glue pasting layer can penetrate into the inside of the limiting groove during the curing process, forming a more compact combination with the friction part and the surface of the wire rope. This penetration effect not only enhances the adhesion between the glue pasting layer and the limiting rubber strip and the wire rope, but also further improves the fixing effect of the limiting groove.

[0044] The existence of the friction part enables the wire rope to more evenly disperse the stress to each part of the limiting groove when subjected to external forces. This stress dispersion effect helps to reduce the risk of local stress concentration and improve the overall strength and durability of the joint.

[0045] The connected design of the glue overflow hole and the limiting groove enables the glue pasting layer to fully fill the inside of the limiting groove, reducing the stress concentration phenomenon caused by insufficient glue or uneven distribution. This helps to extend the service life of the joint and reduce the risk of damage caused by stress concentration.

[0046] The design of the limiting groove and the friction part makes the installation process of the wire rope simpler and faster. The installer only needs to snap the wire rope into the limiting groove, and the initial fixation can be achieved through the friction part. Subsequently, the glue pasting layer penetrates into the inside of the limiting groove through the glue overflow hole to complete the final fixation process. This design reduces the installation difficulty and complexity and improves the installation efficiency.

[0047] The design of the glue overflow hole also facilitates the maintenance personnel to check the curing condition of the glue pasting layer. By observing whether there is glue overflowing from the glue overflow hole and the curing degree of the glue, the connection quality and stability of the joint can be preliminarily judged. In addition, when maintenance or replacement of the joint is required, local repair or cleaning work can also be carried out through the glue overflow hole.

[0048] In summary, the present application includes at least one of the following beneficial technical effects:

[0049] 1. The design of this quick joint makes the installation process simpler and faster, reducing the maintenance cost and time cost; at the same time, the aramid wire rope has high connection strength, can shorten the length of the joint, and can reduce the damage to the original structure of the conveyor belt surface by reserving the aramid wire rope.

[0050] 2. During installation, the glue pasting layer can provide certain positioning and fixing functions, enabling the wire rope to be more easily arranged and fixed according to the design requirements. During maintenance, if inspection or repair of the joint is required, the glue pasting layer can also provide certain convenience and operability.

[0051] 3. The design of the glue overflow hole also facilitates maintenance personnel to inspect the curing condition of the glue application layer. By observing whether there is glue overflowing from the glue overflow hole and the degree of glue curing, the connection quality and stability of the joint can be preliminarily judged. In addition, when maintenance or replacement of the joint is required, local repair or cleaning work can also be carried out through the glue overflow hole. Description of the Drawings

[0060] The conveyor belt surface 100 is in the shape of a long strip, which is the core part of the aramid conveyor belt. It is mainly composed of aramid fibers (D-aromatic polyamide fibers) as the warp, and the weft and binder yarns are composed of polyamide fibers (P) or polyester fibers (E), forming a canvas structure with straight warp and straight weft. The lower cover rubber layer 600 and the upper cover rubber layer 600 are attached in sequence on the outside; both the first aramid ropes 700 and the second aramid ropes 800 are integrally formed on the canvas structure and have a reserve at both ends of the conveyor belt surface 100. The first aramid ropes 700 and the second aramid ropes 800 are directly formed by the warp or woven by multiple warps. The first connector 200 and the second connector 300 are respectively formed at both ends of the conveyor belt surface 100.

Among them, the spacing distance between the shorter first aramid cord 700 and the second joint 300 is 100mm, and the spacing distance between the longer first aramid cord 700 and the second joint 300 is 150mm.

[0063] There is a spacing distance between one end of the second aramid cord 800 away from the second joint 300 and the first joint 200. The spacing distance is 100mm - 150mm. Among them, the spacing distance between the shorter second aramid cord 800 and the first joint 200 is 100mm, and the spacing distance between the longer second aramid cord 800 and the first joint 200 is 150mm.

[0064] Among them, both the first aramid cord 700 and the second aramid cord 800 adopt 1670dtex - 4*5; the single - strand breaking force ≥ 4.5KN.

[0065] For the convenience of stress dispersion, there is a gap between the first aramid cord 700 and the second aramid cord 800, and a filler rubber layer connected to the rubberized layer 400 is formed.

[0066] Refer to Figure 1 and Figure 2 , on both sides of the first joint 200, first chamfers 210 are provided. One ends of the two first chamfers 210 close to the first aramid cord 700 are close to each other; on both sides of one end of the second joint 300 close to the first joint 200, second chamfers 310 are provided. One ends of the two second chamfers 310 close to the second aramid cord 800 are close to each other.

[0067] Among them, the rubberized layer 400 is formed on both sides of the first aramid cord 700, and by applying filler rubber, the gaps between the first aramid cord 700 and the second aramid cord 800 and its own gaps are filled; one end of the rubberized layer 400 is bonded to the first chamfer 210 of the first joint 200, and the end of the rubberized layer 400 away from the first joint 200 is bonded to the second chamfer 310 of the second joint 300.

[0068] The reinforcing layer 500 is bonded to the side of the rubberized layer 400 away from the first aramid cord 700, and one end is bonded to the first chamfer 210 and the other end is bonded to the second chamfer 310; the cover rubber layer 600 is bonded to the side of the reinforcing layer 500 away from the rubberized layer 400, and one end is connected to the first chamfer 210 and the other end is connected to the second chamfer 310.

Then lay one side of the adhesive layer 400, smooth the first aramid rope 700, coat the filling rubber on its surface, and lay them on the adhesive layer 400 on one side in sequence. Then smooth the second aramid rope 800, coat the filling rubber on its surface, and lay them on the laid adhesive layer 400 in sequence, and make the first aramid rope 700 and the second aramid rope 800 arranged at intervals. Then coat the filling rubber again so that a filling rubber layer is formed between the first aramid rope 700 and the second aramid rope 800, and the gaps between the first aramid rope 700 and the second aramid rope 800 are filled with the filling rubber. Then bond the other layer of the adhesive layer 400, and bond the reinforcing layer 500 and the covering rubber layer 600 in sequence, so that the first joint 200, the second joint 300, the first aramid rope 700, the second aramid rope 800, the adhesive layer 400, the reinforcing layer 500 and the covering rubber layer 600 form a whole, and then vulcanize.

[0070] Embodiment 2: Refer to Figure 3 and Figure 4 , the difference between this embodiment and Embodiment 1 is that two groups of limiting members are bonded on the adhesive layer 400. The two groups of limiting members are respectively pasted on the side walls of the two layers of the adhesive layer 400 close to each other, and the two groups of limiting members are arranged at intervals; each group of limiting members includes a plurality of limiting rubber strips 910. The length direction of the limiting rubber strips 910 is arranged along the width direction of the conveyor belt surface 100. A plurality of limiting grooves 911 are formed on the limiting rubber strips 910. The plurality of limiting grooves 911 are equally spaced along the length direction of the limiting rubber strips 910, and the spacing distance between adjacent limiting grooves 911 is the distance between adjacent first aramid ropes 700 and second aramid ropes 800.

The overflow holes 913 are correspondingly arranged and communicated with the limiting grooves 911, and are filled with filling rubber.

[0071] In order to further increase the connection force between the limiting rubber strip 910 and the first aramid rope 700 and / or the second aramid rope 800, a friction part 912 is formed in the limiting groove 911. The friction part 912 is uneven and is pressed against the first aramid rope 700 or the second aramid rope 800.

[0072] In order to further improve the overall tolerance of the connection, connection holes are provided in multiple limiting rubber strips 910. The axis of the connection hole is parallel to the axis of the first aramid cord 700. A connection strip 920 is inserted into the connection hole. Both the connection strip 920 and the limiting rubber strip 910 have elasticity. The material of the connection strip 920 is the same as that of the first aramid cord 700, and a plurality of limiting rubber rings are clamped on the connection strip 920. The limiting rubber rings correspond to the limiting rubber strips 910, and limiting rubber rings are provided on both sides in the width direction of the limiting rubber strip 910.

[0074] 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.
