Fully automatic cigarette bead machineAlso known as bead blasting machine, it is mainly used as a pellet production equipment in the pharmaceutical and tobacco industries. The equipment is used for refrigeration PLC、 The touch screen, seasoning jar, etc. are controlled intensively and have a high degree of automation. It has the characteristics of small footprint, easy operation, and high yield rate. Below, the editor will briefly introduce the maintenance of the fully automatic cigarette bead machine:
1、 Daily maintenance: Basic maintenance before and after daily startup and shutdown
1. Pre startup inspection and preparation
•Equipment appearance and wiring: Clean the body, operation panel, and screen dust, check if the power and air supply connections are secure and undamaged, and adjust the air supply pressure to the rated range.
•Key component status: Check the forming mold, conveyor track, and discharge port, use a dedicated brush to clean residual materials and foreign objects, and avoid material jamming.
•Lubrication and liquid level: Check the lubrication condition of the transmission chain and gears, and add special lubricating oil according to the "fixed point and quantity" when dry; Check the hydraulic oil and coolant levels, and if they are insufficient, add the same type of medium.
2. Cleaning and resetting after shutdown
•Global cleaning: Disassemble protective covers, hoppers, and other components, clean internal dead corners and debris with compressed air, wipe adhesive areas with specialized solvents, and clean concealed components with a disc drive.
•Component positioning and protection: Clean small parts and assemble them in a standardized manner, paying attention to sequence and tightness; Close the main valve and cover the precision component surface with a dust cover.
2、 Regular maintenance: periodic deep maintenance and performance calibration
1. Weekly special maintenance
•Maintenance of transmission system: Remove the chain guard, clean the chain with kerosene, air dry and add oil, adjust the tension; Apply lubricating grease to the meshing parts of the gears.
•Molding system calibration: Check the sealing and alignment accuracy of the mold, adjust the bolts and calibrate the parameters when there is deviation, clean the exhaust holes to prevent blockage.
•Testing system debugging: calibrate weight and size sensors, test errors with standard parts, clean probes to prevent stains from affecting accuracy.
2. Monthly in-depth maintenance
•Hydraulic and pneumatic systems: Check the quality of hydraulic oil, replace and clean the filter screen pipeline if it is cloudy; Exhaust and drain the pneumatic components, replace the aging sealing ring, and test the cylinder action.
•Electrical system maintenance: Use a vacuum cleaner to clean the dust in the electrical control cabinet, check the wiring terminals, clean the contactor contacts, and backup the operating parameters.
•Replacement of vulnerable parts: Replace worn conveyor belts, gaskets, etc., check the cutting edge, and polish or replace if worn.
3、 Fault prevention and special scenario maintenance
1. Common hazard investigation
•Blockage prevention: Check the feeding, conveying, and recycling systems daily, clean the filter screen regularly, and clean the powder spraying and feeding components according to frequency.
•Accuracy maintenance: Monitor equipment vibration weekly, and check anchor bolts and bearings for abnormalities; Regularly calibrate the positioning sensor.
•Security guarantee: Monthly testing of emergency stop and overload protection devices, checking equipment grounding and leakage protection.
2. Maintenance under special working conditions
•Damp environment: Install a dehumidification device in the electric cabinet to shorten the hydraulic oil replacement cycle, and add rust inhibitor during lubrication.
•High load production: Add lubricating oil once a day, check chain tension every 3 days, and cool down the mold during production intervals.
•Long term shutdown: If the shutdown lasts for more than 15 days, drain the hydraulic oil and coolant, perform rust prevention treatment, and run empty for 30 minutes every month.
4、 Maintenance precautions and standards
•Operation protection: Wear gloves and goggles during maintenance, avoid solvent contact with the skin; Do not open the protective cover during equipment operation, and hang a "No Operation" sign for maintenance.
•Consumables management: Use original factory adapted consumables, prohibit mixing specifications, record replacement information in detail and archive.
•Problem response: If the equipment is abnormal, immediately shut down and self check the fault. If it cannot be resolved, contact professional personnel.
