As a core component in the field of industrial conveying, metal mesh belts are suitable for material conveying needs under different working conditions with diverse structural designs and stable transmission performance. The following provides a detailed explanation from three aspects: type classification, core characteristics, and application scenarios.
1、Core types and structural characteristics of metal mesh belts
Metal mesh belts can be divided into 21 mainstream types based on structural design, transmission mode, and application scenarios. The core advantages and applicable scenarios of each type of mesh belt are as follows:
a. Crankshaft type mesh belt: By integrating the comprehensive advantages of metal wire braided mesh belts, the spiral coils are precisely positioned through deeply curved strings, minimizing deformation and extension during belt operation. This makes them ideal for medium to light-load conveying scenarios where high belt stability is required.
b. Direct-axis mesh belt: The mesh is formed by alternating left and right mesh strips connected by straight string strips, with high mesh density and uniform spacing, and strong operational stability. It is particularly suitable for conveying materials with small volume and heavy texture (such as small metal parts).
c. Flat wire mesh belt: Made from flattened wire material, paired with a crankshaft-type threading system to achieve spiral wire positioning, effectively reducing mesh belt deformation; fine workmanship, smooth surface, parallel edges, excellent material durability, suitable for high-precision conveying needs.
d. Type B mesh belt (trapezoidal mesh / straight mesh): It is mostly designed with gear transmission, with outstanding breathability and uniform tension distribution. It features flexible rotation, stable operation, high temperature resistance, pressure resistance, corrosion resistance, and long service life, and is widely used for medium and high temperature conveying.
e. Herringbone mesh belt: The mesh is made of four straight strips connected to alternating left and right mesh strips, requiring extremely high craftsmanship and raw materials. The mesh is fine and dense, with flexible operation, and can accurately carry small materials (such as electronic components, micro parts), making it suitable for precision conveyor lines.
f. Metal mesh belt (Great Wall mesh): It is made of flat metal sheets and round metal wires, with light self-weight, large mesh gaps, and a flat and non-offset mesh surface. It can withstand multiple process scenarios such as washing, drying, cooling, and heat treatment, and is suitable for multi-process linkage conveying.
g. Chain-bar mesh belt: Relying on chain drive, it has strong carrying capacity and is suitable for large and heavy material conveyance. It runs smoothly and has concentrated transmission torque, with small force on the mesh surface, effectively protecting the conveying carrier. Although the cost is higher, its service life is significantly better than conventional mesh belts.
h. Eye-type mesh belt: Using chain wheel drive, it has excellent operational stability and load capacity, and can transport heavy objects moving at high speed. The smooth surface can avoid damaging unstable products, and has a high porosity rate, good ventilation and dehydration effect, and is easy to clean, especially suitable for coating operations (reducing the contact area between materials and mesh belts).
i. Chain-type mesh belt: Using a chain as the power source, the mesh belt is formed by connecting chain segments to small tubes. The spacing between mesh belts can be customized according to actual needs, with a wide range of specifications to accommodate flexible conveyance of materials of various sizes.
j. Chain-type mesh belt: The net belt is driven by a small shaft driven by a chain. The net belt adopts a combined structure of “rolled teeth and strings + left and right net strings”. The large net strings are built with small shafts, and the ends of the small shafts are embedded in the chain holes. The transmission is smooth and the transmission torque is small, making it suitable for continuous conveyance of medium and light loads.
k. U-shaped chain mesh belt (spiral mesh belt): The product is manufactured using an imported computer-controlled mesh belt machine, ensuring high strength and minimal deformation of the mesh surface. Its core advantage lies in its excellent turning performance, allowing for smooth 180° turns. Additionally, the mesh surface is flat, with strong load-bearing capacity, and features ventilation, breathability, cleanliness, non-toxicity, and easy cleaning. Maintenance and disassembly are convenient, and side ribs can be added as needed.
l. Chain plate mesh belt: Driven by stainless steel chains and made of stainless steel plates, it is suitable for conveying small and high-density materials such as metal scraps and fine chemical raw materials. It runs smoothly, is easy to install and replace, and has a high cost but long service life, with outstanding wear resistance and corrosion resistance.
m. Barrier type mesh belt: The design adopts hard edge processing, making the conveying path intuitive and clear. The blocking piece is processed into a straight groove shape through S-shaped processing, which can effectively prevent material deviation. However, mechanical extrusion should be avoided during use. If the blocking piece falls off, it needs to be repaired in a timely manner.
n. Triangle baffle type mesh belt: The edge design is lightweight and sturdy, suitable for conveying larger-sized workpieces, and can prevent materials from slipping off the edges. With fine workmanship, reliable quality, and high cost performance, it is widely used in food processing, metal heat treatment, and other industries.
o. Bar type mesh belt: The structure is simple, breathable, and has strong carrying capacity, allowing for the transportation of heavier materials. It is easy to clean and maintain, and operates flexibly, making it suitable for scenarios that require both ventilation and carrying capacity (such as drying bulk materials).
p. Flanged mesh belt: It is mostly a “combined balanced four-string single head” structure, with the strings not extending to the edge, and with 15-30 cm high flaps on both sides to prevent material spillage; typical application scenarios include fiber conveying in chemical fiber factories, heat treatment of standard parts, bearing cleaning machines, etc., which can effectively prevent small materials from scattering.
q. Spherical mesh belt: The ball-shaped spiral structure is woven from four spiral coils, which is strong and has a large effective filtration area. It is mainly used for filtration in the chemical industry and drying in vacuum dryers. Currently, it is widely adapted to equipment such as viscose fiber folding machines and leather industry dryers.
r. Carrier type mesh belt: The mesh surface is smooth and clean, and the operation is flexible, relying on high-precision equipment and tooling to ensure quality. It has a large carrying capacity and wide mesh holes, suitable for long-distance conveyor lines with large materials (such as heavy components and finished packaging products).
s. Reinforced mesh belt: The string can be selected as straight or curved, and the edge of the mesh belt can be customized with a baffle or overall flanging. The string can be processed into a stepped edge (twisted edge), and the material and structure can be flexibly adjusted according to the usage temperature and working conditions, adapting to high-load and strong wear scenarios.
t. Single rotary mesh belt: Adopting the single-rotating weaving process, the mesh belt boasts uniform texture and high tensile strength. With parallel sides and a smooth surface, it is ideal for medium to light-duty conveying applications that demand flatness and tensile strength.
u. Diamond mesh belt (chain link fence / flexible mesh): The raw materials are selected from high-quality low-carbon steel wire, stainless steel wire or PVC coated wire, and are formed through crochet craftsmanship; the weaving is simple, the appearance is beautiful, and the practicality is strong, suitable for the conveyance and sorting of light materials (such as textile finished products, plastic parts).
