Four-Pillar Screen Printing In-line Line (GE2513H)

Four-Pillar Screen Printing In-line Line (GE2513H)

Our GE2513H four-pillar screen printing in-line line is purpose-built for stainless steel sheet surface printing followed by conveyorized UV curing. The integrated system combines four process stages — loading conveyor, four-pillar precision screen printer, inspection conveyor, and UV curing conveyor — into a single left-in / right-out flow. Designed for 2500×1300mm sheets from 1mm to 2mm thick, the line delivers ±0.15mm registration accuracy, consistent ink deposition, and inline UV curing in one continuous operation.

This in-line configuration eliminates manual handling between printing and curing, reduces floor space, and delivers a higher, more repeatable yield for production-scale stainless steel sheet printing — from decorative panels and appliance surfaces to signage substrates and downstream etching.

How the In-line Line Works

1. Loading conveyor: The operator places stainless steel sheets onto the infeed conveyor. A front start button and a rear sensor (linked to the Mitsubishi PLC) start and stop sheet flow automatically. Stainless-steel rollers driven by a geared motor with VFD deliver a chain-driven, stepless speed range from 0.5 to 16m/min.
2. Four-pillar screen printer: Sheets enter the printer. An aluminum table with three synchronous-belt tracks and vacuum holds the substrate flat within ±0.1mm/m². A Mitsubishi FX3U PLC with Weintek HMI controls registration, squeegee/flood cycle, off-contact height, single- or double-pass print, and fault diagnostics. Squeegee and flood speeds are independently adjustable from 200 to 700mm/s with 0 to 35° angle.
3. Inspection conveyor: After printing, sheets pass onto the inspection conveyor. A sensor confirms sheet position before release to the UV section.
4. UV curing conveyor: Sheets enter the UV section. Three 11KW lamps with a 365nm main peak wavelength, mounted above a stainless-steel mesh belt, cure the printed ink. Forced-air cooling removes heat; over-temperature, leakage, light-source overheat, and e-stop protections keep the process safe.

Performance Features

• Precision four-pillar frame — high-rigidity construction maintains squeegee parallelism and registration under continuous shift operation.
• Three-belt vacuum table — 24-40m/min transfer speed with ±0.1mm/m² flatness for distortion-free printing on stainless steel sheets.
• Servo-driven print head — 200-700mm/s squeegee/flood speed with 0-35° angle adjustment, driven by a Leadshine servo on Hiwin linear guides.
• Pneumatic off-contact — 0-25mm adjustable off-contact range for fine-pitch patterns and different ink viscosities.
• Short-side pneumatic screen clamp — quick screen change with ±10mm position adjustment and a position indicator for fast setup.
• Dual safety limits on head lift — both electrical and mechanical end-of-travel protection, plus a 400mm max lift stroke for safe operation.
• Mitsubishi FX3U PLC + Weintek touchscreen — centralized control with fault prompts, VFD-driven squeegee / transfer / conveyor speed, and clean separation between PLC, control, and power circuits.
• Integrated UV section — three 11KW lamps at 365nm main peak wavelength, aluminum gold-plated reflectors, and forced-air cooling for fast, even cure.
• Industrial-grade components — Hiwin linear guides, Leadshine servo, Omron sensors, Airtac pneumatics, Chint contactors, Meanwell power supply.
• Chain-driven conveyors — 0.5-16m/min adjustable speed with stainless-steel rollers / mesh belt for chemical compatibility.

Application Scope

• Stainless steel sheet surface printing for decorative panels, appliance surfaces, and elevator / architectural panels.
• UV-curable ink and coating deposition on metal sheets.
• Large-format pattern printing for 2500×1300mm panels with downstream etching or forming.
• In-line production environments where printing and curing must happen in one continuous flow.

Operational Benefits

• Single-flow production — loading, printing, inspection, and UV curing in one continuous line reduces handling and floor space.
• Repeatable registration — 6-point edge positioning with ±0.15mm accuracy supports fine-pitch patterns on stainless steel.
• Production-scale throughput — 200-700mm/s squeegee speed and 24-40m/min table transfer for high-volume runs.
• Operator-friendly — centralized HMI control with fault prompts, dual safety limits on head lift, and e-stop protection across the line.
• Built for multi-shift — industrial-grade components and protection features (over-temperature, leakage, light-source overheat) intended for continuous operation.
