Detailed Operation Guide for Block Hot Melt Adhesive Production Line
• Pre-Operation Preparation
1. Raw Material Inspection: Confirm EVA/PE/PP/rubber-based raw materials are dry (moisture content ≤0.5%), free of impurities, and meet formula requirements; crush lumps to 5-10mm particles for smooth feeding.
2. Equipment Check: Inspect 304 stainless steel feeding hopper, extrusion screw, and cutting blade for wear; verify electrical connections, air pressure (0.6-0.8MPa), and cooling system circulation.
3. Safety Preparation: Wear heat-resistant gloves, goggles, and anti-slip shoes; ensure emergency stop button is functional and ventilation system is on.
• Parameter Setting
1. Power on the PLC intelligent control panel, select the corresponding formula program (or customize).
2. Set melting temperature (120-180℃ based on raw material), extrusion speed (10-30rpm), mixing time (5-10 mins), and block dimensions (length/width/thickness per demand).
3. Activate preheating and wait for temperature to stabilize (±1℃ deviation allowed) – indicated by the panel’s green light.
• Startup & Operation (Continuous)
1. Start the feeding system first, then the extrusion and mixing unit; ensure raw materials enter the melting chamber evenly.
2. Monitor real-time data on the panel: viscosity (1000-5000 mPa·s), pressure (≤15MPa), and cooling water temperature (20-30℃); adjust parameters if abnormalities occur.
3. Take the first 3-5 finished blocks for inspection (dimension precision ±0.1mm, hardness 60-80 Shore A); proceed with mass production only after qualification.
• Post-Production Shutdown
1. Stop feeding first, let the remaining material in the system be extruded completely.
2. Set temperature to 80℃ for heat preservation, clean the extrusion head and cutting blade with a dedicated tool (avoid scratching).
3. Turn off the extrusion unit, cooling system, and main power; record production data (output, parameters, qualified rate).
4. Store finished blocks in sealed, dry packaging; clean the equipment surface and surrounding area.
1. Pre-Operation Preparation:
Check power supply, heating system, and mechanical parts for abnormalities. Ensure raw materials are dry and meet formula requirements; load them into the feeding hopper.
2. Parameter Setting:
Via PLC touchscreen, set heating temperature, extrusion speed, shaping parameters, and cutting length according to adhesive specifications.
3. Warm-Up & Inspection:
Start the heating system, wait for each zone to reach set temperature (maintain constant temperature for 10-15 mins). Verify temperature stability and feeding system smoothness.
4. Startup & Operation:
Initiate the line in sequence (feeding → extrusion → shaping → cutting). Monitor real-time operation via the control panel to ensure uniform product shape and no blockages.
5. Production Adjustment:
Fine-tune parameters based on product quality (e.g., adjust speed for thickness, temperature for adhesion). Record key data for traceability.
6. Shutdown & Maintenance:
After production, stop feeding first, then shut down each module following system prompts. Clean the extrusion head, shaping mold, and cutting blade; perform routine inspection.
