A very commonly used conveying mechanism in mechanical design; similar mechanisms include belt conveyors, sprocket conveyors, apron chain conveyors, gravity roller conveyors, etc. Common components of mesh belt conveyor systems include: variable frequency motors, reducers, drive shafts, idler shafts, drive pulleys, idler pulleys, deep groove ball bearings, mesh belts, support shafts, legs, guardrails, guardrail supports, crossbeams, and adjustment bases. The power for the mesh belt is generally provided by a variable frequency motor. The belt width is determined based on the size of the materials being conveyed. The motor power and reduction ratio are determined according to the required conveying speed and the volume of the materials, as well as the outer diameter of the drive pulley’s pitch circle. Generally, the frictional force in mesh belt conveyance can be disregarded. The reduction ratio i = input rotational speed / output rotational speed = (π * pulley diameter * 60) / [(material length + spacing between materials) * V]. It is sufficient to select a value slightly larger than this calculated figure. 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 in the middle using support rods and shafts. To increase its length, an additional plate can be attached at the junctions of the metal sheets. Guardrail supports can be installed at intervals of around 500–800 mm. All that’s needed is to drill threaded holes at the corresponding positions on the sides of the metal sheets. The guardrails can be standard ones that 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 is used for light loads, the shaft diameter doesn’t 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 cut into these drive wheels; grooves are created at 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 cut on both sides 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 inside 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. Common components of a belt conveyor system include variable frequency motors, reducers, drive shafts, driven shafts, idler rollers, deep groove ball bearings, belts, support plates, legs, guardrails, guardrail supports, crossbeams, adjustment brackets, sprockets, bearing housings, etc. Compared to mesh belt conveyors, the friction between the belt and the rollers is greater. Its structure is similar to that of previous mesh belt conveyors; the difference is that since the belt is too soft to bear weight, support plates must be added in the middle. Compared to mesh belts, belt drives are prone to deviation. Solutions include creating a convex or concave shape, texturing the rollers, applying rubber coating, and adding guards on both sides of the rollers, among others.
