Automatic All-Silicone Lipstick Filling Machine with Separated Two-Stage Vacuum Device

1. Frame Structure

• Safety cover: Aluminum base with chrome-plated steel surface, combining sturdiness and anti-rust performance.
• Worktable/Electric cabinet/Door: Made of SUS stainless steel for enhanced corrosion resistance.
• Support: Fixed holding feet and detachable material loading station for easy material handling and equipment maintenance.
• Columns: Euro-standard aluminum profiles for lightweight design and modular expansion.
• Door: Stainless steel material, suitable for high-cleanliness production scenarios (e.g., cosmetics, medical industry).

2. Table Drive System

• Slide rail technology: Imported U-shaped circulation slide rail system for smooth movement and precise positioning.
• Molds: 28 sets of precision silicone rubber molds with anodized surface treatment to improve wear resistance and demolding efficiency.
• Lifting control: Servo index control for station lifting, meeting high-precision requirements for multi-station synchronous operation.
• Sealing: Fully sealed moving parts; double-layer insulation and sealing in the cooling area to prevent liquid/gas leakage.

3. Pre-heating Device

• Heaters: 2 units of Swiss imported Leister heaters with adjustable air volume and heating rate.
• Mechanical control: Cylinder-driven up/down movement, handwheel for height adjustment, and timer for heating duration control.
• Temperature control: Digital display with PID control, equipped with a variable-speed air fan, ensuring temperature uniformity within ±2°C.

4. Filling System

• Filling machine: 1 mobile dual-nozzle filler, with servo motors individually controlling the filling volume of each nozzle and supporting secondary mixing function.
• Tanks: 2×30L tanks with an outer cleaning system for quick material changeover and hygiene maintenance.
• Pumps: Quick-joint piston pump driven by a servo motor, with flow control accuracy of ±0.5%.
• Material conveying: Electric heating double-layer hose (only the inner hose needs to be replaced for color adjustment) to reduce material residue and waste.
• Additional features: Nozzle pre-heating, bulk material collection, ceramic heating for tanks, PLC + touch screen control, and dual power supply interfaces.

5. Nozzle Moving System

• Motion control: Cylinder-driven nozzle on/off, forward/backward movement, and horizontal material feeding, with a response speed <0.3 seconds.
• Temperature management: Heating tube to maintain nozzle temperature and prevent material solidification and blockage.
• Bulk collection: SUS stainless steel tray for easy cleaning and material recovery.

6. Re-heat Device

• Equipment: Imported Swiss LEISTER heater with high power density and long service life.
• Adjustment: Handwheel for height adjustment, touch screen for temperature setting, and manual fan volume adjustment to adapt to different product processes.

7. Cooling Unit

• Type: Separated water circulation cooling device with an independent temperature control system.
• Temperature range: Minimum -20°C, suitable for rapid curing processes of wax-based and resinous materials.
• Compressor: 8Hp compressor using R404A refrigerant for stable cooling capacity.
• Structure: Cooling tunnel under the table with pipeline-circulated cold air; double-layer insulation outside the tunnel to reduce cold loss.

8. Discharging Unit

• Movement control: High-precision industrial module (Y/X axis + lifting) with positioning accuracy of ±0.1mm.
• Gripper: 4-piece vacuum gripper, servo motor-driven rotation, and cylinder-driven lifting, compatible with φ8-17.1mm lipsticks.
• Demolding: Self-patented two-jaw vacuum system with adjustable grip tension to reduce product damage.
• Conveyor: Flexible chain-type conveyor for smooth mold transfer and continuous production.

9. Screw Down Unit

• Control: Cylinder-driven gripper on/off and servo motor-driven rotation, with torque control accuracy of ±1%.
• Function: Precisely controls lipstick rotation force to ensure firm bonding between the paste and tube, avoiding over-tightening damage.

Overall Equipment Advantages

1. Material Performance: Extensive use of stainless steel (SUS) and aluminum profiles meets food-grade/medical-grade cleanliness standards.
2. Control Precision: Servo motor + PLC-based motion control ensures key station positioning accuracy of ±0.1mm and filling volume error <1%.
3. Process Adaptability: Supports fast mold switching, independent dual-nozzle control, and multi-level temperature/air volume adjustment, suitable for diverse products (e.g., lipsticks, crayons, medical suppositories).
4. Maintenance Convenience: Detachable loading station, quick-connect pump heads, and inner hose independent replacement design reduce downtime.
5. Safety and Energy Efficiency: Fully sealed moving parts, double-layer insulated cooling tunnel, and dual power supply interfaces ensure operational safety and energy efficiency.
