This machine adopts a track conveyor photoelectric detection system, combined with a mechanical structure to arrange BLQ in an orderly manner for cutting betel nuts. Therefore, it has a delicate appearance, simple operation, stable operation, no hygiene dead corners, low failure rate, high pass rate, and low scrap rate.
Maintenance methods for horizontal betel nut cutting machine:
1、 Daily maintenance
1. Cleaning treatment
Residue cleaning: Immediately remove betel nut residue from blades, conveyor belts, and workbenches after shutdown to prevent acidic substances from corroding metal parts.
Surface wiping: Use food grade cleaning agents to wipe the body (especially the 304 stainless steel parts that come into contact with betel nut) to prevent residual stains.
• Dry protection: After cleaning, wipe off the moisture with a dry cloth. In humid environments, spray rust inhibitor (in accordance with food safety standards).
2. Lubrication management
Lubrication of moving parts: Add food grade lubricating oil to guide rails, transmission chains, and other parts to avoid contamination of products with ordinary industrial oils and fats.
Lubrication cycle: lubricate every 8 hours for continuous operation, and once a day for intermittent use.
3. Tool inspection
Blade status: Check whether the cutting blade is dull or broken, replace it in a timely manner or use specialized sharpening equipment to repair it.
Installation and fastening: Confirm that the blade fixing bolts are not loose to prevent cutting deviation from causing safety accidents.
2、 Regular maintenance
1. Transmission system maintenance
Belt/chain inspection: Adjust the tension of the drive belt and replace components with excessive wear (such as breakage or stretching deformation).
Bearing lubrication: Inject high-temperature grease into the main shaft bearings and roller bearings to reduce friction losses.
2. Electrical system inspection
• Line safety: Check whether the power line and sensor line are aging or damaged, and whether the grounding device is effective.
Control parameter calibration: Verify the sensitivity of the photoelectric sensor (for betel nut positioning) and adjust the cutting parameters of the PLC control program.
3. Maintenance of structural components
Bolt tightening: Conduct a comprehensive inspection of the body's connecting bolts and bracket fasteners to prevent loosening caused by vibration.
Guide rail accuracy calibration: Use a spirit level to check the flatness of the guide rail. If the deviation exceeds 0.1mm, it needs to be recalibrated.
3、 Deep maintenance (quarterly or semi annual)
1. Cooling system maintenance
Clean the heat dissipation components: Clean the dust on the fan and heat sink to ensure that the motor and driver do not overheat.
• Coolant replacement: If the equipment is equipped with a water cooling system, it is necessary to regularly replace the antifreeze coolant and clean the pipelines.
2. Comprehensive lubrication replacement
• Old oil removal: Remove old oil and impurities from the guide rail and gearbox, and refill with the specified type of lubricating oil.
Seal inspection: Replace aging oil seals and O-rings to prevent lubricant leakage from contaminating the product.
3. Safety device testing
Emergency stop function verification: Simulate an emergency situation to trigger the emergency stop button and confirm that the device will immediately power off.
• Effectiveness of protective cover: Check if the protective cover of the moving parts of the machinery is secure to prevent operators from coming into contact with hazardous areas.
4、 Long term disuse maintenance
1. Rust prevention treatment
Coating metal surfaces with oil: Apply food grade rust proof oil to easily rusted parts such as blades and guide rails, and cover them with dust covers.
Dry environment storage: The humidity in the equipment storage area should be controlled below 50%, and desiccants should be placed if necessary.
2. Battery and Circuit Maintenance
Power outage protection: Disconnect the main power supply and remove the backup battery of the control system to prevent liquid corrosion.
• Capacitor discharge: Discharge frequency converters and servo drives to extend the lifespan of electronic components.
5、 Precautions
• Hygiene compliance: All cleaning agents and lubricants must comply with FDA or GB 4806 food contact material standards.
Record management: Establish a maintenance ledger to record the content of each maintenance, replacement of parts, and abnormal situations for easy traceability and analysis.
Professional maintenance: When it comes to precision components such as servo motors and PLC modules, contact the manufacturer or certified technicians for handling.
In short, the maintenance of the horizontal betel nut cutting machine should focus on cleaning and anti-corrosion, tool maintenance, transmission lubrication, and electrical safety. By implementing graded maintenance (daily → regular → in-depth), the lifespan of equipment can be effectively extended, ensuring production hygiene and efficiency.
