What are the common faults and solutions of collagen filling machines?
Collagen filling machines may encounter various operational issues. Below are typical problems and recommended solutions:
Inaccurate Filling or No Material Output
Clogged Valve Core: Disassemble the valve core and clean it by soaking in hot water with detergent. For stubborn residue, rinse with alcohol. If there is completely no output, check for material residue in the hopper.
Worn Seals: Replace aged or ineffective seals with identical specifications. It is advisable to keep commonly used seals in stock.
Unstable Air Pressure: Ensure operating pressure remains stable at approximately 0.6 MPa. Adjust the throttle valve to regulate the filling speed.
Sensor Misalignment: Recalibrate the front limit device if photoelectric positioning is inaccurate. Also, verify key parameters on the touch screen, such as the number of filling units and buffer settings.
Leakage During Filling
Filling Nozzle Issues: Check if the nozzle aperture is too small. Consider switching to a tapered design to reduce backpressure. Also, inspect O-rings for signs of corrosion or wear.
Poor Valve Sealing: Identify air leaks at connections using a soapy water solution. Tighten pipe clamps appropriately or replace sealing materials.
Insufficient Backpressure: Slightly increase the cylinder operating pressure or adjust the valve opening mechanism to ensure a tight seal between the nozzle and container interface.
Irregular Mechanical Operation
Cylinder Movement Issues: Check the guide rail lubrication status-sewing machine oil is recommended for maintenance. Also, inspect solenoid valves and PLC control contacts for proper function.
Equipment Overload Shutdown: If the machine stops due to overload, check the pushing mechanism for blockages, remove any debris, or replace damaged bearings.
Key Operational & Maintenance Notes
Always disconnect power and air supply before performing maintenance, display safety warnings, and use protective equipment as required.
Regularly clean the delivery pipelines (recommended: circulate ~85°C hot water for about 10 minutes) and ensure the pneumatic system remains unobstructed.
Special Note
Given the viscous nature of collagen material, which is prone to causing blockages, regularly inspect the status of valves and filling nozzles as a primary maintenance focus.
