Maintenance and Care Precautions for 16-100mm HEPA Mini Rotary Pleating and Gluing Machine
Combined with the core structures (PLC touch control system, servo motor, hot melt adhesive circuit, double-roller assembly, pneumatic/cooling system, etc.) and process characteristics of the equipment, targeted maintenance and care precautions are formulated, covering four dimensions: daily inspection, regular maintenance, special maintenance and safe operation. These measures are designed to ensure the stable operation of the equipment, extend its service life, and avoid the impact of improper maintenance on the accuracy of pleating and gluing.
I. Daily Inspection (Before Startup / Production Intervals / After Shutdown)
Before startup, check the PLC touch screen and control system to confirm no error codes, sensitive touch response, normal display of all parameters (pleating height, pleating pitch, adhesive bead parameters), no loose or fallen wire connectors, and keep the electric control box dustproof and clean.
Inspect the pneumatic system (pneumatic lift, air shaft, air chuck): Check that the air compressor pressure is within the rated range, no air leakage in air pipes and no loose connectors, the air shaft is firmly fixed after inflation without slipping or deviation.
Check the hot melt adhesive circuit: Before startup, confirm that the adhesive guns and nozzles are unclogged, the adhesive pipes are free of aging and leakage, and the temperature control system displays normally to prevent adhesive burning due to overhigh temperature or adhesion due to overlow temperature; Clean residual adhesive in nozzles in a timely manner during production intervals to avoid solidification and blockage.
Inspect roller assemblies and feeding components: Check that the surface of pleating roller assemblies is free of adhesive residue, impurities and scratches, the feeding rollers are without deviation and wear, no foreign matter jams in the paper conveying path, and confirm the normal response of paper skew adjustment function.
Inspect the cooling and tension system: Check that the bilateral pneumatic cooling air outlets are unclogged with smooth air output, the powder brake operates without abnormal noise, and the coil tension adjustment knob is flexible to operate without jamming.
Conduct overall cleaning after shutdown: Remove residual adhesive and paper scraps from the machine body, roller assemblies and adhesive circuit, wipe the surface of metal parts, turn off the main power supply, air source and adhesive circuit temperature control, and cover the equipment surface for dustproof protection.
II. Regular Maintenance (Divided by production hours/cycles, recommended based on an 8-hour shift)
Weekly Maintenance
Apply high-temperature resistant and wear-resistant special lubricating grease to moving parts such as servo motors, roller bearings and adjusting screw rods to avoid dry friction; Ensure an appropriate amount of lubricating grease to prevent adhesion of paper scraps and adhesive.
Disassemble hot melt adhesive nozzles for deep cleaning, remove internal residues of adhesive guns with special cleaning agent, check no deformation of adhesive outlets of nozzles, and test the uniformity of adhesive output after installation.
Inspect all metal fasteners (roller assemblies, pneumatic components, frame), and tighten loose bolts and nuts to prevent component deviation caused by equipment vibration during operation and avoid affecting pleating accuracy.
Clean dust on the surface of the powder brake and check the tension control accuracy. If tension is unstable or the coil slips, clean the magnetic powder chamber or replace magnetic powder in a timely manner.
Monthly Maintenance
Conduct rust prevention inspection on all metal parts of the equipment (especially QPQ-treated roller assemblies and frame parts). If the surface coating is worn or scratched, spray special rust inhibitor in a timely manner to avoid corrosion.
Test the wiring terminals and line insulation of the PLC control system, clean dust inside the electric control box (use a dry cloth/high-pressure air gun, no water allowed), and check the normal operation of the cooling fan.
Inspect the filter and oil-water separator of the pneumatic system, drain water and replace filter elements in a timely manner to prevent moisture and impurities from entering the air circuit and causing malfunctions of pneumatic valve groups and air cylinders.
Calibrate the pleating height/pitch adjustment accuracy of the servo motor, compare the touch screen parameters with the actual pleating size, and contact professional personnel for parameter correction if there is a deviation.
Inspect the temperature control sensors and heating tubes of the hot melt adhesive circuit, test the heating speed and constant temperature effect of different temperature gears, and replace accessories in a timely manner if heating is uneven or temperature control is inaccurate.
Quarterly / Annual Maintenance
Fully disassemble roller assemblies and bearing components, inspect roller surface wear and bearing clearance, and replace accessories in a timely manner if the roller surface has severe scratches or the bearing has abnormal noise/looseness; Recalibrate the parallelism of roller assemblies after installation to avoid pleating deviation.
Test the paper skew adjustment valve group and intermittent gluing valve group of the double-roller machine, check the sealing performance and response speed of valve cores, and replace aging seals to ensure the normal function of valve groups.
Conduct a comprehensive inspection of the whole machine's circuit, air circuit and adhesive circuit, replace aging air pipes, wires and adhesive hoses, inspect the operation status of the hot melt adhesive pump, and conduct proper maintenance and calibration of the pump body.
Conduct a comprehensive accuracy test (pleating height, pleating pitch, gluing position accuracy) on the equipment annually, and perform overall debugging by professional technicians to restore the equipment to its optimal operating state.
III. Special Maintenance for Core Components
1. Hot Melt Adhesive Circuit (Core Area Prone to Malfunctions)
Do not use inferior hot melt adhesive; use the adhesive type specified for the equipment (e.g., high/low temperature hot melt adhesive) to prevent adhesive carbonization and circuit blockage.
If the adhesive circuit is out of service for a long time (more than 24 hours), thoroughly clean residual adhesive in adhesive guns and pipes to prevent pipeline blockage caused by solidification and hardening of adhesive.
Adjust the adhesive temperature gradually; do not sharply raise or lower the temperature in an instant to avoid damage to heating tubes due to thermal expansion and contraction.
2. Servo Motor and PLC Control System
Keep the servo motor ventilated and dry, prevent adhesive and paper scraps from entering the motor, and clean the blocked motor cooling fan in a timely manner.
Avoid scratching the PLC touch screen with sharp objects and contact with water/adhesive; wipe with a soft dry cloth when cleaning.
Non-professionals are prohibited from arbitrarily modifying internal parameters of the PLC. If a system error occurs, record the error code first, then contact technicians for troubleshooting, and do not force startup.
3. Roller Assemblies and Metal Wear-Resistant Parts (Key Factors Affecting Pleating Accuracy)
Do not scrape the surface of pleating and gluing roller assemblies with hard tools; use special soft scrapers and dust-free cloths with special cleaning agent to remove residual adhesive/paper scraps.
Avoid contact of QPQ-treated metal parts with strong acid and strong alkali to prevent coating corrosion and failure and reduction of wear resistance.
4. Pneumatic and Cooling System
Do not knock or impact pneumatic components (air cylinders, valve groups, air shafts); the inflation pressure of the air shaft shall not exceed the rated value to prevent shaft damage.
Regularly clean dust and paper scraps from bilateral pneumatic cooling air outlets to keep smooth air output, avoiding poor pleat setting and material deformation caused by uneven cooling.
IV. General Safety and Operation Specifications for Maintenance and Care
All maintenance and care operations must be carried out after the equipment is shut down, the main power supply is cut off, and the air source/adhesive circuit temperature control is turned off. Operating the equipment with power on is strictly prohibited to prevent pinching, electric shock and scald from high-temperature adhesive.
When cleaning the hot melt adhesive circuit or replacing adhesive guns/nozzles, wait for the adhesive circuit temperature to drop to a safe range and wear high-temperature resistant gloves to avoid scald from high-temperature components.
Use industrial special products for lubricants, cleaning agents, rust inhibitors and other materials for equipment maintenance; mixing different types of lubricating grease and cleaning agents is strictly prohibited to prevent component damage.
Prioritize original matching accessories when replacing parts (e.g., roller assemblies, nozzles, servo motor accessories, pneumatic seals) to avoid the impact of non-original accessories on equipment operation performance and pleating/gluing quality due to inaccurate precision.
Establish an equipment maintenance and care record book to record daily inspection problems, regular maintenance content, accessory replacement time and accuracy calibration results, facilitating the traceability of equipment operation status and early troubleshooting of potential faults.
If the equipment is out of service for a long time (more than 1 week), thoroughly clean the whole machine, apply lubricating grease to moving parts, exhaust residual air from the air circuit, clean the adhesive circuit completely, conduct comprehensive dustproof, rustproof and moistureproof treatment on the equipment, and run the equipment idly for 10-15 minutes regularly to inspect the function of all components.
Maintenance personnel must take professional training before taking up their posts and be familiar with equipment structure and operation procedures; unauthorized disassembly and debugging of core equipment components (e.g., PLC, servo motor, hot melt adhesive pump) is strictly prohibited.
