I am building a new converting line and need a purpose-built, metal automatic paper take-off unit. Core dimensions are fixed: the expanding air shaft must be Ø74 mm and the web width 2 000 mm. Drive will come from an AC gear motor, so please size and specify a model that delivers smooth, adjustable unwind speed without introducing vibration. Stable web tension is critical, therefore I want a dancer-type tension rod fitted with a sensor and closed-loop, fully automatic control. All control hardware, wiring diagrams, and PLC/HMI logic (if required) should be part of the package so the unit can slot straight into the rest of my line. Directly after the take-off section I need an IR dryer with an integrated fan. It has to mount on the same frame, clear the 2 000 mm web, and deliver even drying at production speed. Please recommend lamp power, airflow, shielding, and any safety interlocks you deem necessary. Deliverables • 3D CAD model and detailed 2D fabrication drawings of the complete assembly • Motor sizing calculations and manufacturer datasheets for the AC gear motor • Control architecture, wiring diagrams, PLC/HMI program or ladder logic printout • Bill of materials with commercially available parts and suggested suppliers • Installation, alignment, and commissioning guidelines • Remote sign-off support once the machine is on my floor Acceptance criteria • Shaft diameter, web width, and mounting footprints match the figures above • Web tension remains within ±2 % of the setpoint across the full speed range • IR dryer achieves target moisture reduction without scorching at max line speed • All documentation is delivered in editable formats (STEP, DWG, PDF, and native controls files)

El eje de 74 mm que alimenta la cinta puede generar resonancia si el motor no está acoplado, lo que afecta la tensión del papel. Seleccionaré un motor AC con control de frecuencia que permita ajuste fino sin sacudir la estructura. Luego montaré el sensor dancer y programaré el PLC con lógica de lazo cerrado para mantener la tensión dentro del ±2 %. Un error frecuente es colocar el secador IR sin considerar la distribución del flujo de aire, lo que produce puntos calientes y humedad residual. Con la ventilación calculada y la protección adecuada, el cliente verá un secado uniforme a velocidad de línea y recibirá documentación lista para producción.
