A PVC 90-degree curved conveyor belt is a conveyor system designed with a right-angle curve (90°), allowing products to change direction from a straight line to a perpendicular path while maintaining continuous, stable movement without disrupting product orientation.
This type of conveyor uses a flexible PVC belt that can follow the curved frame geometry, helping optimize factory space - especially in corner areas, tight layouts, or production lines that require flexible routing.
Structure of a PVC 90-Degree Curved Conveyor
A standard PVC curved conveyor system typically consists of the following main components:
Conveyor Frame
The frame is made from powder-coated steel, galvanized steel, or stainless steel (201/304), ensuring durability and corrosion resistance.
It is precisely curved at a 90° angle to maintain structural rigidity and load-bearing capacity. This makes it suitable for various environments such as dry, humid, food-grade, or light chemical conditions.
PVC Conveyor Belt
The PVC belt used in curved conveyors typically has a thickness of 2–5 mm and is fabricated to match the curved profile for smooth operation. One side of the belt is perforated and fitted with guide rollers or tracking elements to maintain alignment and prevent deviation when running through the curve.
The belt surface can be smooth or anti-slip, depending on the application and type of product being transported.
Tapered Pulley and Roller System
- The system uses tapered pulleys to balance the speed difference between the inner and outer edges of the belt. This ensures stable operation and prevents belt misalignment.
- Materials include steel, stainless steel, or plastic, with optional rubber or PU coating to improve grip and reduce slipping.
Motor and Drive System
- The conveyor is typically equipped with a motor ranging from 180W to 0.75kW, suitable for various production needs.
- Speed can be flexibly adjusted using an inverter (VFD) to synchronize with other equipment.
- Power transmission is achieved via gearbox, chain, or belt drive systems, ensuring stable performance.
Control System
- The control system is integrated into an electrical cabinet mounted under the frame.
- It includes basic functions such as ON/OFF, emergency stop, and speed control.
- The design is simple, user-friendly, and easy to maintain.

Applications of PVC 90-Degree Curved Conveyor
PVC curved conveyors are widely used across various industries:
- Food industry: Transporting snacks, beverages, and packaged food between processing, labeling, and packing stages while maintaining hygiene and smooth operation
- Garment industry: Moving semi-finished products (clothing, accessories) between sewing, inspection, and packing areas to optimize workflow
- Logistics & warehousing: Connecting straight conveyor lines in sorting systems, enabling direction changes for cartons and small packages without interrupting flow
- Electronics industry: Handling components and circuit boards with stable, low-vibration movement to prevent damage
