[0002] A conveyor belt is a device used to transport materials. There are many types of conveyor belts, and conveyor belts made of different materials have different effects.

[0029] It should be noted here that: in the process of conveying materials by the conveyor belt body 1, a bearing layer 101 with a multi-layer high-strength steel wire rope core is used, which has extremely high tensile strength and flexibility. Each steel wire rope is twisted by multiple strands of fine steel wires, and the outer layer is specially galvanized or plastic-plated to improve its corrosion resistance. The spacing between the steel wire ropes is accurately calculated, which can not only ensure the strength of the conveyor belt body 1, but also make the conveyor belt body 1 bear tension evenly, reducing local stress concentration. A buffer layer 102 composed of rubber and fiber fabric is arranged on the upper and lower sides of the bearing layer 101. The rubber has good elasticity and buffering performance, which can absorb the impact force of the conveyor belt body 1 during operation and reduce damage to the bearing layer 101. At the same time, the covering layer 103 in direct contact with the material is made of highly wear-resistant and aging-resistant rubber material, and its thickness is generally 3-8mm. The surface of the covering layer 103 can be designed into different patterns to increase the friction between the conveyor belt body 1 and the material and prevent the material from slipping.

[0030] In addition, a special edge reinforcement structure is adopted at the edge of the conveyor belt body 1. Multiple layers of high-strength fiber fabrics can be wrapped around the edge of the conveyor belt at a specific angle to form a strong edge reinforcement layer 104, which is then tightly combined with the covering layer 103 of the conveyor belt body 1. This edge reinforcement structure can effectively prevent the edge of the conveyor belt body 1 from tearing when subjected to tension, thereby improving the overall tensile resistance of the conveyor belt body 1.

Each adjustment column 403 is provided with a driving assembly for driving the adjustment plate 404, and the two connecting plates 402 are provided with a detection assembly for detecting the tension of the conveyor belt body 1;

[0036] It should be noted here that the two baffles 406 are provided to provide guidance and limiting functions for the rotation of the conveyor belt body 1, thereby reducing the risk of positional displacement of the conveyor belt body 1 during material transportation.

[0042] It should be noted here that: through the setting of the moving component, in the process of rotation of each moving rod 701, the two threaded strips 702 with opposite thread rotation directions on its side wall will be driven to rotate, and then under the threaded engagement transmission action of the two threaded strips 702 and the driving plate 502 and the guiding action of the guide component, the two driving plates 502 are driven to move closer to each other. In the process of the two driving plates 502 moving closer to each other, the adjustment plate 404 on one side of the square plate 504 will be pushed to move closer to the conveyor belt body 1, thereby realizing the extrusion and pushing of the conveyor belt body 1.

[0043] See also Figure 4 and Figure 7 One of the two connecting plates 402 shown in the figure is provided with a linkage assembly for synchronously rotating each moving rod 701, the linkage assembly includes a plurality of linkage rods rotatably connected to the connecting plate 402, one end of each linkage rod is connected to the moving rod 701, the two side walls at the edge of each linkage rod are fixedly connected to a transmission wheel 801, the several side walls in the middle of each linkage rod are fixedly connected to two transmission wheels 801, and two adjacent transmission wheels 801 are connected by a transmission belt 802;

[0045] See also Figure 4 and Figure 7 , one side of the connecting plate 402 in the figure is fixedly connected to an L-shaped plate 803, and the side of the L-shaped plate 803 away from the connecting plate 402 is fixedly connected to a motor 804, and the output end of the motor 804 is connected to one of the linkage rods;

[0046] It should be noted here that the motor 804 is configured to drive one of the linkage rods to rotate.

[0047] It is worth noting that the model of motor 804 is Y80M1-2. As a prior art, its specific structure and working principle have been mastered by people in this field and will not be elaborated here.

[0048] See also Figure 4 The detection assembly shown in the figure includes a U-shaped plate 901 fixedly connected to the two connecting plates 402 close to the conveyor belt body 1, the U-shaped plate 901 is provided with a distance sensor 902, the detection end of the distance sensor 902 is arranged opposite to the conveyor belt body 1, and the distance sensor 902 is electrically connected to the motor 804 through the controller;

[0049] It should be noted here that: by setting up the detection component, it is used to detect the sinking distance of one side of the conveyor belt body 1 for conveying materials, and then realize the detection of the tension of the conveyor belt body 1, so as to provide accurate data reference for the tension adjustment of the conveyor belt body 1.

[0050] It is worth noting that the model of the distance sensor 902 is AC-M18-A50 / 100. As a prior art, its specific structure and working principle have been mastered by people in this field, and will not be elaborated here.

[0051] Working principle: When the conveyor belt body 1 is in use, the conveyor belt body 1 is firstly sleeved on two conveyor rollers 3, and then the conveyor rollers 3 are rotated to drive the conveyor belt body 1 to rotate, and then during the rotation of the conveyor belt body 1, the material is transported;

[0052] In the process of the conveyor belt body 1 conveying materials, a bearing layer 101 with a multi-layer high-strength steel wire rope core is used, which has extremely high tensile strength and flexibility. Each steel wire rope is twisted by multiple strands of fine steel wires, and the outer layer is specially galvanized or plastic-plated to improve its corrosion resistance. The spacing between the steel wire ropes is accurately calculated, which can not only ensure the strength of the conveyor belt body 1, but also make the conveyor belt body 1 bear tension evenly, reducing local stress concentration. A buffer layer 102 composed of rubber and fiber fabric is arranged on the upper and lower sides of the bearing layer 101. The rubber has good elasticity and buffering performance, which can absorb the impact force of the conveyor belt body 1 during operation and reduce damage to the bearing layer 101. At the same time, the covering layer 103 in direct contact with the material is made of highly wear-resistant and aging-resistant rubber material, and its thickness is generally 3-8mm. The surface of the covering layer 103 can be designed with different patterns to increase the friction between the conveyor belt body 1 and the material and prevent the material from slipping.

[0053] In addition, a special edge reinforcement structure is used at the edge of the conveyor belt body 1. Multiple layers of high-strength fiber fabrics can be wound around the edge of the conveyor belt at a specific angle to form a strong edge reinforcement layer 104, which is then tightly combined with the cover layer 103 of the conveyor belt body 1. This edge reinforcement structure can effectively prevent the edge of the conveyor belt body 1 from tearing when subjected to tension, thereby improving the overall elongation resistance of the conveyor belt body 1.

[0054] Therefore, under the action of the bearing layer 101 of the multi-layer high-strength steel wire rope core and the special edge reinforcement layer 104, the conveyor belt body 1 has extremely strong tensile resistance and can withstand large tensile forces without elongation, deformation or breakage, so that the conveyor belt body 1 has high tensile resistance. At the same time, the buffer layer 102 composed of rubber and fiber fabric effectively absorbs the impact force received by the conveyor belt body 1 during operation, protects the bearing layer 101, and prolongs the service life of the conveyor belt body 1. The highly wear-resistant and aging-resistant rubber covering layer 103 enables the conveyor belt body 1 to adapt to various harsh working environments, reduces the replacement frequency caused by wear and aging, and reduces maintenance costs.

[0055] At the same time, during the material conveying process of the conveyor belt body 1, the distance sensor 902 can be used to detect the sinking distance of the material conveying side of the conveyor belt body 1. If the sinking distance of the material conveying side of the conveyor belt body 1 exceeds the set threshold, the distance sensor 902 will send an electrical signal to the controller, and then under the control of the controller, the motor 804 is started, and the motor 804 drives one of the linkage rods to rotate. During the rotation of one of the linkage rods, the transmission belt 802 and the transmission wheel 801 will drive the moving rod 701 at one end of each linkage rod to rotate;

[0056] During the rotation of each moving rod 701, the two threaded strips 702 of the side wall which are arranged in opposite directions of thread rotation will be driven to rotate, and then the two driving plates 502 will be driven to move closer to each other under the threaded meshing transmission action of the two threaded strips 702 and the driving plate 502 and the guiding action of the guide assembly. During the movement of the two driving plates 502 closer to each other, the adjustment plate 404 on one side of the square plate 504 will be pushed to move closer to the conveyor belt body 1, thereby squeezing and pushing the conveyor belt body 1, thereby realizing automatic adjustment of the tension of the conveyor belt body 1, ensuring that the conveyor belt body 1 is always in a state of uniform force during operation, avoiding the problems of slipping and deviation of the conveyor belt body 1 due to relaxation, and thus improving the tensile resistance of the conveyor belt body 1.
