Plastic Modular Conveyor Belt
Clean. Strong. Smart. That’s Modular.
The Backbone of Your Production Line: More Than Just a Belt
Modular conveyor belts are the core components of modern automated packaging lines. They are more than just simple “conveyor belts”; they are critical to ensuring a smooth, hygienic, and efficient flow of products from weighing and organizing to the final packaging. Unlike traditional flat belts, modular conveyor belts are composed of a series of interlocked plastic modules, much like LEGO bricks, providing unparalleled flexibility, durability, and ease of maintenance.
Is Your Conveyor System Facing These Challenges?
Problem 1: Belt Mistracking and Serpentine Movement
- We use high-precision molds for one-piece injection molding, ensuring that the dimensions and pinhole positions of each module are highly consistent.
- Precise pitch control fundamentally eliminates the tolerance accumulation that causes serpentine movement, ensuring the belt runs straight along its entire length.
Problem 2: Difficult to Clean, Promoting Bacterial Growth
- Our belts feature an open-hinge design that allows high-pressure water jets to pass through directly, easily washing away debris.
- The surface is specially treated to be smooth and non-porous, complying with FDA food-grade standards, inhibiting bacterial adhesion and making cleaning tasks much easier.
Problem 3: Belt Breakage or Module Damage
- We insist on using 100% virgin engineering plastics (such as POM, PP), never adding any recycled materials, to ensure superior mechanical strength and durability.
- We offer a variety of material options for different application scenarios to cope with harsh environments such as high temperatures, low temperatures, oil, or chemicals.
Problem 4: Complex Replacement, High Maintenance Costs
- A unique pin-locking system allows for easy removal and installation of individual modules with just a screwdriver, no special tools required.
- If a part of the belt is damaged, you only need to replace the damaged modules, not the entire belt, significantly reducing maintenance costs and repair time.
What Is a Modular Conveyor Belt?
A modular plastic conveyor belt, also known as a plastic chain conveyor belt, is constructed from a series of thermoplastic modules linked together with solid plastic rods. Unlike traditional belts, modular belts utilize a “bricklayed” pattern, enabling custom widths and enhanced lateral strength. These belts are positively driven by sprockets, eliminating slipping and increasing reliability—ideal for high-load, high-precision tasks
Types of Modular Conveyor Belts
Surface Type | Description | Best Use Case |
Flat Top | Smooth, solid surface | General purpose, conveying packaged goods, cartons, or trays. Easy to clean. |
Flush Grid | Open grid surface | Applications requiring drainage, airflow, or passage of small debris (e.g., washing vegetables, cooling baked goods). |
Raised Rib | Elevated ribs running along the belt | Lifts products to allow for bottom-side processing or to run on specific tracks. |
Friction Top | High-friction inserts on the surface | Incline or decline conveyors, preventing product slippage. |
Roller Top | Embedded rollers on the surface | Low-pressure accumulation zones, allowing products to queue without damaging the belt or drive. |
Perforated Flat Top | Flat surface with small holes | Combines a smooth surface with drainage capabilities, ideal for dewatering delicate products. |
The Science of Pitch & Sprocket Matching
- Pitch: The distance between the centers of two adjacent module pins. Common pitches include 12.5mm, 17.5mm, 25.4mm, and 54.8mm.
- Small Pitch: Ideal for tight transfers and conveying small products.
- Large Pitch: Suitable for heavy-duty applications and longer conveyor runs.
- Sprocket Matching: The sprocket teeth must perfectly engage with the belt’s underside. We offer both engineering plastic and stainless steel sprockets to match your chosen belt and application environment.
Material Showdown: POM vs. PP
POM (Polyoxymethylene): The All-Rounder
- Core Advantages: High mechanical strength, excellent wear resistance, low coefficient of friction.
- Applicable Scenarios: General food conveying at ambient temperatures, applications requiring a flat, scratch-resistant surface.
- Recommendation: For most standard packaging conveyor applications, POM is the most cost-effective and reliable choice.
PP (Polypropylene): The Chemical-Resistant and Economical Option
- Core Advantages: Excellent chemical resistance, good fatigue resistance, cost-effective.
- Applicable Scenarios: Primary processing of products requiring frequent washing (vegetables, fruits, seafood), environments with acidic or alkaline substances.
- Recommendation: When chemical resistance and cost are the primary considerations, PP is the ideal choice.
Industry Applications
Modular conveyor belts are widely used across many industries due to their versatility and cleanability:
| Industry | Application Examples |
|---|---|
| Food Processing & Beverage | Meat, seafood, baked goods, fruit, vegetable washing & packing lines. |
| Pharmaceuticals | Transport of tablets, capsules, and liquid bottles in sterile environments. |
| Automotive & Battery Lines | Heavy component conveying, electric battery module assembly. |
| Packaging & Container Handling | Bottles, cans, and boxes—stable transport and gentle accumulation. |
| E-Commerce & Warehousing | High-speed sortation and parcel routing in logistics hubs. |
| Special Processes | Cooling, drying, washing—Flush Grid and Perforated Top designs are ideal. |
Maintenance Tips
- Routine Inspection: Regularly check for cracks, wear, or broken modules. Damaged parts can be replaced individually without tools.
- Cleaning: Use food-safe cleaners to maintain hygiene. Open-grid designs are especially easy to rinse and sanitize.
- Drive Alignment: Ensure sprockets and shafts are aligned for smooth tracking and to avoid skipping or wear.
- Frame & Accessories: Check guides, side rails, and motors to prevent vibration or material jamming.
How to Select the Right Belt: A Step-by-Step Guide
- Identify the Application: What are you conveying? What are the environmental conditions?
- Choose the Surface Type: Flat Top, Flush Grid, etc.
- Determine the Pitch: Measure the distance between module pins.
- Select the Material: POM or PP.
- Specify the Width and Length.
