Automatic Idler Conveyor Roller Making Machine High Speed Continuous PLC Control

Conveyor Roller Making Machine Offering High Speed Continuous Welding and Automatic Feeding for Steel Conveyor Rollers

This dedicated dual-torch welder is engineered for synchronous circumferential welding on both ends of conveyor idler steel tubes. It completes bilateral welds in one continuous cycle, delivering a maximum welding speed of 2000 mm/min — nearly double the output of conventional units, which typically run at 800–900 mm/min. This high-speed capability makes it ideal for idler manufacturers running high-volume, continuous production lines.

The machine adopts a PLC control system paired with an intuitive HMI touchscreen. It locks in repeatable welding parameters batch after batch, forming uniform, consistent weld beads and cutting reject rates caused by inconsistent manual operation. Its left and right spindle housings feature a center-synchronous adjustment structure to guarantee coaxiality during welding. A hybrid manual-auto stop assembly integrates with automated lifting and lowering actuators. Operators only load and unload pipes manually; positioning, clamping, welding and resetting proceed automatically. Parameter tuning is straightforward and stable, raising the overall automation level of your roller fabrication workshop.

Its fixed-workpiece architecture secures the steel tube after clamping, while welding torches orbit the pipe for circumferential seam welding. This orbital welding layout minimizes vibration and positional drift, supporting superior machining precision. Heavy-duty hydraulic clamps, PLC-controlled feed modules and precision timing circuits are fitted as standard. The torch advances automatically for welding and retracts rapidly once the cycle finishes, with high repeat positioning accuracy to ensure consistent dimensional results for every finished idler.

Beyond tube welding, this multi-function machine supports fabric hemming. It comes with a pneumatic crease bar that delivers neat, precise fold lines for different textile materials. A foot pedal switch enables hands-free start and pause, freeing operators to arrange fabrics. The built-in alignment gauge helps butt edges neatly, prevents offset seams and improves splicing consistency for fabrics of varying thickness and texture.
