A transmission mechanism that is very commonly used in mechanical design; similar ones include belt conveyors, sprocket conveyors, plate chain conveyors, and gravity-fed roller conveyors, among others. The typical components of a mesh belt conveyor system are: variable-frequency motor, reducer, drive shaft, transmission shaft, drive wheel, idler wheel, deep groove ball bearings, mesh belt, support shafts, legs, guardrails, guardrail supports, crossbeams, and adjustment brackets. The power for driving the mesh belt usually comes from a variable-frequency motor. The belt width is determined based on the volume of the material being transported, while the motor power and reduction ratio are determined according to the desired conveying speed, the volume of the material, and the outer diameter of the drive wheel’s tooth crest. In general, the friction involved in mesh belt conveyors can be disregarded. The reduction ratio i is calculated as input speed/output speed = (π * wheel diameter * 60) / (material length + spacing between materials) * V; it is sufficient to choose a value that is slightly higher than this ratio. The main body of the mesh belt conveyor chain typically consists of plates that are bent about 3 mm on each side, or they can be straight plates; these plates are fixed together using support rods and shafts. To increase its length, an additional plate can be attached at the joints between the metal sheets. Guardrail supports can be installed at intervals of around 500–800 mm. All that is needed is to drill threaded holes in the corresponding positions on the metal sheets on both sides. The guardrails can be standard types, which can be simply locked in place. It’s worth noting that a bent support plate needs to be added in the middle of the mesh belt to ensure overall strength. Transition plates can be used on both sides to seal the structure, or transition transmission chains can also be installed. The drive shaft is connected to the motor. Since the mesh belt operates under light loads, the shaft diameter does not need to be very large; a diameter of around 25 is sufficient. Deep groove ball bearings are installed on the left side of the shaft, and two drive wheels are fixed to this shaft. Keyways need to be created on these drive wheels; grooves are made in the corresponding positions on the drive shaft during installation, and elastic retaining rings are used to secure the wheels on either side of the shaft. As for the driven part, similar to the drive shaft, grooves are created on either side of the driven shaft wheels, and elastic retaining rings are used to fix these wheels. The driven wheels need to be modified so that 2–4 deep groove ball bearings can be installed in them. As shown in the diagram, adjustment brackets need to be installed at both ends of the driven shaft to allow for adjusting the tension of the mesh belt.
