The maintenance method of the roller type dressing slicer needs to be systematically managed based on the mechanical structure characteristics and usage scenarios, which can be divided into the following core steps:
1、 Tool system maintenance
1. Blade cleaning and rust prevention
Immediately remove any remaining dressing debris from the blade surface after each use to avoid corroding the blade edge.
When stored for a long time, apply anti rust oil and wrap the blade with a protective cover to prevent oxidation or collision.
2. Blade inspection and replacement
Regularly check the flatness of the blade, and replace it promptly if there is a broken or curled blade; It is recommended to replace vulnerable parts such as rolling needles and core shafts every 500 hours or in groups according to production volume.
When replacing the blade, it is necessary to calibrate the clearance between the tool holder and the rolling cutter to avoid uneven slicing caused by misalignment.
2、 Lubrication of mechanical components
1. Lubrication of moving parts
Add food grade lubricating oil to components such as guide rails, tool holder bearings, and transmission gears every week to ensure smooth operation and reduce wear.
After lubrication, excess oil stains should be wiped off to prevent contamination of the dressing or adhesion of debris.
2. Drive system inspection
Check the operation status of servo motors and reducers every month and monitor for any abnormal noises; Synchronously check the tension of the belt to avoid slipping and affecting the slicing accuracy.
3、 Cleaning and Pollution Prevention Management
1. Cleaning inside and outside the equipment
After daily work, use a lint free cloth and neutral cleaning agent to wipe the equipment casing and conveyor belt, with a focus on cleaning areas such as rolling cutter gaps and debris troughs that are prone to scale buildup.
Thoroughly clean internal pipelines and sensor probes every week to prevent residue from blocking or interfering with signals.
2. Coolant and lubricant management
Low viscosity coolant (such as engine oil mixed with diesel oil) is used to reduce the working temperature of the hob, and the ratio is adjusted according to the processing materials (such as elastic cloth, hydrogel).
Regularly replace the circulating coolant to avoid lubrication failure or product contamination caused by deterioration.
4、 Electrical and control system maintenance
1. Circuit and sensor inspection
Before starting up daily, check whether the power lines and grounding devices are intact to ensure there is no risk of leakage.
Regularly calibrate photoelectric sensors and visual positioning systems to ensure slice size accuracy (within ± 1.0mm error).
2. Software and parameter backup
Upgrade the PLC control program every quarter, backup production parameters (such as coating speed and slice thickness), and prevent data loss from affecting production continuity.
5、 Periodic deep maintenance
1. Quarterly maintenance
Disassemble the knife holder, conveyor belt and other modules, check the wear of the bearings, and replace the sealing ring or needle roller if necessary.
Perform air tightness testing on pneumatic components such as inflation shafts and air knives, clean filters, and replace aging air pipes.
2. Annual maintenance
Entrust a professional team to calibrate the transmission accuracy of the entire machine, test the load performance of the servo motor, and replace aging electrical components.
6、 Summary of Technical Points
1. Preventive maintenance: Reduce the rate of sudden failures by developing maintenance plans such as daily cleaning, weekly lubrication, and quarterly calibration.
2. Operating standards: Operators need to be trained and on duty. Overloading or using non matching consumables (such as non-standard saw blades) is strictly prohibited.
3. Advantages of modular design: Most rolling cutter equipment adopts a split structure, which facilitates local maintenance without affecting overall production.
By implementing the multi-dimensional maintenance strategy mentioned above, the lifespan of the equipment can be significantly extended, ensuring the stability and hygiene standards of medical dressing slices.
