Belt-Type Weight Sorting Machine Installation Specifications & Guidelines
I. Foundation Requirements
- Positioning & Leveling
- Surface: Install on concrete base with flatness ≤2mm/m².
- Space Requirements:
- Front/rear conveyor extension: ≥1.5m
- Side maintenance access: ≥0.8m
- Top inspection space: ≥1.2m
- Leveling:
- Tools: Frame or bar level
- Calibration sequence: Weighing module → Sorting module
- Tolerances:
- Longitudinal: ≤0.5mm/m
- Transverse: ≤0.3mm/m
- Anchor Bolts:
- Use M16 chemical anchors (e.g., HILTI HVA or equivalent).
- Torque: 120–150N·m
- Ground resistance: ≤4Ω (verify with tester).
II. Electrical System
- Power Supply:
- Control circuit: 220V±2%, 50Hz.
- Grounding:
- Use 50×50×2500mm galvanized steel angle, driven vertically (top ≥0.6m below ground).
- Connect with 40×4mm galvanized flat steel (spacing ≥3m between rods).
- For simple grounding: Use steel stakes.
III. Mechanical Setup
- Conveyor Belt Tension: Adjust to proper tightness.
- Weighing Calibration:
- Static Calibration:
- Use 500g standard weights.
- Steps:
- Zero calibration (3 cycles empty).
- Load 20%, 50%, then 100% of capacity.
- Error tolerance: ≤±0.1% of full scale.
- Static Calibration:
IV. Safety & Environment
- Mechanical Guards: Install protective covers around moving parts.
- Operating Conditions:
- Temperature: 0–40°C (ideal: 20±5°C).
- Humidity: ≤85% RH (no condensation).
- Vibration: ≤0.5g (10–150Hz).
V. Test Run Checklist
- Pre-Start Checks:
- Tighten all bolts (use torque wrench).
- Lubricate bearings (NLGI 2# lithium grease).
- Test air lines (hold 0.6MPa for 30min).
- Load Test (8hrs):
- Motor temperature rise: ≤60K.
- Noise: ≤75dB(A).
- Power usage: ≤10% deviation from rated value.
Post-Installation Notes:
- Recheck leveling after 72 hours of operation.
- Perform preventive maintenance every 2,000 working hours.
- It is also applicable to other sorting machine, tray sorting machine, visual sorting machine, etc. Leveling after installation is the first step. Please feel free to contact me: [email protected]
