[0002] In the manufacturing process of the traditional large inclination angle belt conveyor, the welding method is often used to connect the frame and the key components. Although this method is simple to operate, it is very rough. The high temperature generated during the welding process can easily cause the metal structural parts to deform, affecting the precision and stability of the entire conveyor. After long-term operation, the welded parts may also crack due to stress concentration, greatly shortening the service life of the equipment.

[0003] In the material conveying link, the existing technology has serious defects. Due to the unreasonable design of the internal structure of the conveyor, the material is easily entangled on the conveying components such as the roller and the carrier roller during the conveying process. The material entanglement not only increases the resistance of the equipment operation, causing the motor load to be too large, but also may cause local wear of the conveying belt, affecting its normal operation. At the same time, the unreasonable setting of the baffle or protective structure can easily cause the material blocking phenomenon. The accumulation of material in the local position of the conveying path hinders the smooth conveying of the material, not only reduces the conveying efficiency, but also may cause equipment failure due to the accumulation of material, further increasing the risk of production interruption and maintenance cost.

[0036] The main core components of the above embodiments are:

[0037] ① Belt pressing wheel and belt blocking wheel assembly

[0038] Pressing pulley setting: Choose several polyurethane material pressing pulleys with a diameter of 100mm, install them on the elbow assembly through shaft and bearing side by side. The center distance between adjacent pressing pulleys is set to 150mm to ensure that it can evenly cover and press the upper surface of the conveying belt. The pressing pulley of this material has good wear resistance and flexibility, which can effectively reduce the wear of the belt and provide stable pressure.

[0039] Belt blocking wheel setting: The belt blocking wheel is also made of polyurethane material with a diameter of 80mm. The belt blocking wheel is distributed in a triangular shape with the pressing pulley, and the installation position of the belt blocking wheel is calculated accurately to make the included angle between the blocking surface of the belt blocking wheel and the center line of the adjacent two pressing pulleys between 55°-65°, and 60° in this embodiment. Such angle distribution can provide the best lateral restraint for the conveying belt and effectively prevent the belt from deviating at the transition position.

[0040] ②Elbow assembly

[0041] Support frame installation: The support frame of the elbow assembly is made of high-strength Q345 steel and can be detachably installed on the rack of the belt conveyor on both sides through M16 bolts. On each support frame, there is a diamond-shaped bearing seat UCFLU204 corresponding to the position of the two ends of the lower pressing belt roller. This bearing seat has strong carrying capacity and can ensure the stable rotation of the lower pressing belt roller.

[0042] Installation process: When installing the elbow assembly, first align the support frame with the pre-set installation hole position on the rack, then tighten the bolts. Then install the lower pressing belt roller on the fixed external bearing seat to ensure that the lower pressing belt roller can rotate flexibly. The whole installation process is simple and convenient, and it is easy to maintain and replace parts later.

[0043] ③Belt blocking wheel assembly installation

[0044] Installation groove design: On the support frame corresponding to the position of the belt blocking wheel assembly, the groove is directly opened during laser cutting during sheet metal cutting stage. The shape of the groove is an inverted "convex" character, which is accurately matched with the size of the belt blocking wheel shaft. After the belt blocking wheel assembly is installed, its blocking surface protrudes 18mm from the inner side of the support frame to ensure that it can fully contact and effectively block the side of the conveying belt.

[0045] Installation and debugging: When installing the belt blocking wheel assembly, first put the belt blocking wheel shaft into the installation groove, adjust the gasket to fine-tune the position of the belt blocking wheel, ensure that the blocking surface maintains appropriate contact pressure with the side of the conveying belt, and then tighten the bolts. After installation, perform no-load debugging to check the rotation flexibility of the belt blocking wheel and the blocking effect on the belt. If necessary, it can be fine-tuned again.

[0046] ④Conveying belt structure implementation

[0047] Baffle plate setting: A baffle plate is integrally formed every 500mm around the conveyor surface of the conveyor belt.

[0048] Material stop skirt installation: The material stop skirt is made of rubber with a thickness of 5mm and is integrally formed with both sides of the conveyor belt through a vulcanization process. The skirt width is 60mm, which can effectively prevent small materials from leaking from the edge of the belt and enhance the sealing of material conveying.

[0049] Installation of support rollers and bearing wheels

[0050] Upper support roller installation: Install one upper support roller every 1200mm below the upper conveyor surface of the corresponding conveyor belt on the frame. The upper support roller has an outer diameter of φ89mm, is made of seamless steel pipe, and has a chrome-plated surface to improve its wear resistance and rust prevention. The upper support roller has an external bearing housing connected to the frame. Holes are pre-drilled in the sheet metal frame. During installation, ensure that the axis of the upper support roller is perpendicular to the running direction of the conveyor belt.

[0051] Support Roller Installation: Three support rollers are arranged side-by-side, located on both sides of the material retaining skirt and in the middle of the conveyor belt. The support rollers are φ230mm in diameter, made of nylon, and possess good self-lubricating and wear-resistant properties. The center-to-center distance between adjacent support rollers is set at 350mm, based on the belt width. The support rollers are mounted on the frame using brackets. After installation, the height of the support rollers is adjusted to ensure they evenly support the lower surface of the conveyor belt.

[0052] The working process of the above equipment

[0053] Pre-start inspection: Before starting the belt conveyor, check that all components are securely installed and that the pressure roller, belt guide roller, lower pressure roller, upper support roller, and support roller can rotate freely. Also check that the conveyor belt tension is appropriate and that the baffle plates and skirts are undamaged.

[0054] Material conveying process: The motor is started, driving the conveyor belt. The material is placed on the conveyor belt in the horizontal conveying section and moves with the belt. When the material reaches the transition position between the horizontal and inclined conveying sections, the pressure roller applies pressure to the upper belt surface to keep the belt flat; the guide roller blocks the belt from the side to prevent it from deviating; the lower pressure roller applies pressure to the lower belt surface to ensure stable operation of the lower belt. The upper support roller and the support roller provide support for the upper and lower conveying surfaces respectively, ensuring smooth belt operation. Throughout the conveying process, the baffle plate and baffle skirt effectively prevent material from falling and leaking.

[0055] Maintenance and upkeep: Regularly inspect and maintain all components, such as adding lubricating oil to the bearings of the pressure roller, guide roller, lower pressure roller, upper support roller, and support roller; checking for loose bolts; and replacing severely worn parts promptly. Additionally, regularly clean residual material from the conveyor belt to keep the equipment clean and extend its service life.
