[0024] 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.

[0025] Belt conveyors mainly consist of belts, drive units, and frames. The belt is one of the core components, serving as the medium for carrying and transporting materials, and is typically made of multiple layers of composite materials. Common belt materials include rubber and PVC (polyvinyl chloride). The belt structure generally includes a cover layer, belt core, and edges. The cover layer primarily protects the belt core and provides friction; its thickness and material are selected based on the characteristics of the conveyed material and the working environment. The belt core is the belt's skeleton, determining its strength and load-bearing capacity, and is usually made of polyester, nylon, or other fiber fabrics or steel wire rope. The edges are designed to prevent tearing or other damage during operation and are typically specially edge-wrapped.

[0026] The drive unit is the part that provides power to the belt conveyor, mainly including the motor, reducer, and drive roller. The motor is the power source, and its power is determined by factors such as the conveyor's conveying capacity, conveying speed, and conveying distance. The reducer reduces the motor's output speed while increasing the torque, enabling the drive roller to drive the belt at a suitable speed and with sufficient force. The drive roller is in direct contact with the belt, driving the belt to move through friction. The surface of the drive roller usually has a certain pattern or roughness to increase the friction between it and the belt. The diameter and length of the drive roller also need to be designed according to factors such as the belt width and conveying capacity. Generally speaking, the larger the diameter, the larger the contact area with the belt, and the greater the friction, which is more conducive to the stable operation of the belt.

[0027] The frame is the skeleton of a belt conveyor, used to support and fix other components, such as the drive unit, idlers, and tensioning devices. Frames come in two structural forms: fixed and mobile. Fixed frames are generally used for conveyors fixed in factory buildings or on the ground; they have a more robust structure and can withstand greater weight and impact. Mobile frames, on the other hand, are movable, facilitating the movement of the conveyor between different work locations and are typically used in temporary or highly flexible applications. Frames are generally made of steel and assembled using welding or bolting. When designing a frame, factors such as the conveyor's length, width, height, and conveying capacity must be considered to ensure the frame provides sufficient support strength and stability.

[0028] Roller conveyors generally consist of a drive roller, a drive unit, and a frame. The frame is the skeleton of the roller conveyor, which supports the roller and bears the weight of the conveyed objects. It is usually made of metal materials (such as steel) and has sufficient strength and rigidity. The drive unit generally consists of a chain, a motor, and gears. Gears are usually installed at the rotating connection between the drive roller and the frame. The gears on the motor mesh with the chain, driving the gears on the drive roller to rotate, thereby driving the roller to roll and convey the materials.

[0029] Please refer to the above description for a better understanding of the embodiments of this utility model.

[0030] Example: Please refer to Figs. 1 to 4 According to an embodiment of this utility model, a technical solution is provided: a multi-directional positioning conveying structure for a belt conveyor, comprising: a first belt conveyor 1; a second belt conveyor 2, wherein the discharge direction of the first belt conveyor 1 is opposite to that of the second belt conveyor 2; and a receiving mechanism, comprising a frame 3, a third belt conveyor 4, a roller conveyor 5, a scissor lift 6, and a support plate 7. The third belt conveyor 4 is fixed on the frame 3, and there are gaps between the multiple belts of the third belt conveyor 4. Multiple rollers of the roller conveyor 5 are spaced apart in the gaps between the multiple belts of the third belt conveyor 4. The scissor lift 6 is located at the bottom of the frame 3, and the support plate 7 is fixed on the lifting end of the scissor lift 6. The roller conveyor 5 is fixed on the support plate 7, and the scissor lift 6 drives the roller conveyor 5 to rise and fall. The support surfaces of the second belt conveyor 2 and the third belt conveyor 4 are parallel.

[0031] The multi-directional positioning conveyor structure of the belt conveyor described above, in the initial transportation stage, the scissor lift 6 raises the roller conveyor 5, making the support surface of the roller conveyor 5 parallel to the support surface of the first conveyor. At this time, the rollers of the roller conveyor 5 are higher than the belt of the third belt conveyor 4. Then, the scissor lift 6 drives the roller conveyor 5 to slowly descend until the rollers of the roller conveyor 5 are lower than the belt of the third belt conveyor 4. The goods can then be conveyed from the third belt conveyor 4 to the second conveyor. Due to the cooperation between the scissor lift 6 and the roller conveyor 5, heavy materials descend slowly, and the impact caused during material reception is smaller, which can effectively protect the third belt conveyor 4. Compared with the traditional conveyor structure, the belt in this structure is not easy to break, has a longer service life, and is more stable. It is worth promoting and solves the problem in the existing technology that the belt needs to be tightened and loosened repeatedly every time it receives material, which makes the belt easy to break or the belt loose and unable to abut against the output shaft, making it difficult for the output shaft to drive the belt.

[0032] To facilitate cargo transportation and material receiving, the third belt conveyor 4 can effectively receive materials. Instead of materials getting stuck between the first belt conveyor 1 and the third belt conveyor 4, or between the first belt conveyor 1 and the roller conveyor 5, the height of the first belt conveyor needs to be adjusted so that the support surface of the first belt conveyor 1 is higher than the support surface of the third belt conveyor 4.

[0033] During the operation of a belt conveyor, materials may deviate from their designated path on the belt due to various factors. For example, if the belt is improperly installed or the tension on both sides is uneven, the belt itself may run off-track, causing the materials to also deviate. Therefore, guide plates 8 are fixed to both sides of the first belt conveyor 1 and the second belt conveyor 2. The guide plates 8 can restrict the lateral movement of the materials, confining them within the reasonable range of the belt and ensuring that the materials can be accurately transported to their destination.

[0034] During operation, the belts of the first belt conveyor and the second belt conveyor 2 need to bear the weight of the material. The first roller 9 under the belt can provide support for the belt and prevent the belt from sagging excessively due to the weight of the material. For example, in a long-distance material conveying belt conveyor, if there are not enough rollers to support it, the belt may be severely deformed due to the weight of the material, or it may even rub or collide with other parts, affecting the normal operation of the equipment. Therefore, the first roller 9 is rotatably connected to the bottom of the belts of the first belt conveyor 1 and the second belt conveyor 2.

[0035] A support plate 10 is installed at the bottom of the belt of the third belt conveyor 4. The support plate 10 is fixed to the frame 3. A second roller 11 is rotatably connected at the contact point between the support plate 10 and the belt of the third belt conveyor 4. The support plate 10 and the second roller 11 mainly serve to support the belt. During the operation of the belt conveyor, the belt needs to carry materials for transportation. Installing the support plate 10 and the second roller 11 can effectively prevent the belt from sagging excessively due to the weight of the materials.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
