What should be paid attention to during daily maintenance of a block machine?
Daily maintenance of a block machine is crucial to ensuring proper operation, extending its service life, and improving production efficiency and product quality. The following are key points to note during daily maintenance:
1. Pre-shift Inspection (Must be performed before starting the machine)
Appearance and Connection Inspection
Inspect all equipment components (frame, mold, press head, material distribution system, etc.) for looseness, deformation, or damage. Pay particular attention to fasteners such as bolts and nuts to ensure they are properly tightened.
Check that the mold is clean and free of residual material or debris to prevent impacting block forming accuracy.
Check that the pallet is intact and free of cracks or deformation. Unqualified pallets should be replaced promptly to prevent damage to the formed blocks or equipment jamming.
Lubrication System Inspection
Check all lubrication points (such as bearings, gears, and guide rails) for sufficient lubricant/grease and cleanliness according to the equipment manual. Add or replace any insufficient oil/grease promptly (it is recommended to use the lubricant specified for the equipment).
Ensure that the lubrication system's oil circuits are unobstructed and free of blockages. Hydraulic System Inspection
Check the oil level in the hydraulic tank. If it falls below the minimum mark, refill with the same type of hydraulic oil immediately (note that the hydraulic oil must be filtered before adding to prevent contaminants).
Inspect the hydraulic lines for leaks, damage, or loose joints. Address any issues promptly.
Check the hydraulic system's pressure gauge, oil temperature gauge, and other instruments for proper display and ensure the system pressure is within the specified range (normal pressure values are generally listed in the equipment manual).
Electrical Control System Inspection
Check the power and control cables for secure connections, damage, or deterioration, and for reliable grounding.
Test control components such as operating buttons, touch screens, and PLCs for responsiveness and effectiveness, and for indicator lights to illuminate properly.
II. Mid-Shift Inspections (Regular Inspections During Production)
Operational Status Monitoring
Monitor the operating sound of the equipment. If any unusual noises (such as metallic clashing or squealing) are detected, immediately stop the machine for inspection and troubleshooting. Restart the machine after correcting any problems.
Observe the quality of the block formation. Issues such as chipped corners, cracks, or insufficient density may indicate mold wear, uneven material distribution, or abnormal pressure/vibration parameters, requiring prompt adjustment or repair. Monitor the hydraulic system oil temperature; it should generally not exceed 60°C. If the oil temperature is too high, shut down the machine and check whether the cooling system (such as the cooling fan and radiator) is functioning properly. Replace the hydraulic oil if necessary.

Inspection of Key Components

Vibration System: Check the operating status of the vibration motor or vibrator to ensure normal amplitude and frequency, and that the connecting bolts are not loose (bolts on vibration components are prone to loosening due to high-frequency vibration and require special inspection).

Material Distribution System: Observe the smooth operation of the distribution trolley, the uniform distribution of material, and any jamming or leakage. Clean any remaining material in the distribution hopper promptly.

III. Post-Shift Maintenance (Must-Do After All-Downtime)

Cleaning

Thoroughly clean any remaining material from the surface and interior of the equipment, especially areas such as the mold cavity, ram, distribution hopper, and vibration platform, to prevent solidification and impact on subsequent production. (Use a high-pressure water jet or specialized tools for cleaning, but be careful to avoid water entering the motor, electrical control box, and other areas.)

Clean any debris from the pallets and stack them neatly to prevent deformation. Component Reset and Protection
Reset the press head, die, fabric trolley, and other components to their initial positions to prevent deformation due to long-term stress.
If the equipment is shut down for an extended period (more than one day), apply anti-rust oil to rust-prone areas such as the die and press head. Cover exposed metal surfaces with a tarp or plastic sheet to protect them from moisture.
Data Recording
Record the equipment's operating hours, production volume, any abnormalities encountered, and their resolution to provide a reference for subsequent maintenance.
IV. Regular Maintenance (Perform according to the equipment manual)
Lubrication System
Regularly replace the lubricating oil/grease (generally monthly or every 500 hours of operation, as specified in the manual). Clean the lubricated areas during replacements to prevent contamination of the new oil by residual oil.
Hydraulic System
Replace the hydraulic oil every six months to one year. Clean the hydraulic oil tank and filter (check the filter element regularly and replace it if clogged) to prevent oil contamination and wear on hydraulic components.
Inspect vulnerable parts such as the hydraulic cylinder and seals. Replace any leaks or deterioration. Mechanical Components
Inspect molds for wear. If cavity wear causes dimensional deviations in the blocks, repair or replace them.
Check transmission components such as gears, chains, and belts for tightness and wear, and adjust or replace them promptly to ensure smooth transmission.
Inspect rotating components such as bearings and replace any abnormal noises or excessive clearance.
Electrical Control System
Regularly clean the PLC control cabinet, touch screen, and other components to remove dust. Check for loose terminals to prevent contact problems.
Test the accuracy of sensors (such as position sensors and pressure sensors) to ensure proper signal transmission.
V. Special Precautions
Safety Operation: During maintenance, power must be disconnected and a "Do Not Close" sign must be displayed to prevent accidents caused by misoperation. When inspecting the hydraulic system, release system pressure first to prevent hydraulic fluid from spraying and injuring personnel.
Environmental Management: Keep the equipment's working environment clean and free of dust and water. In particular, keep the electronic control system and motor away from humid and corrosive environments. Spare parts reserve: always keep wearing parts (such as seals, filter elements, bolts, bearings, etc.) on hand so that they can be quickly replaced in case of failure, thus reducing downtime.
