Unpacking and feeding equipment

Unpacking and feeding equipmentAs the core equipment for powder processing in industries such as chemical, food, and building materials, its maintenance work needs to revolve around cleaning, lubrication, fastening, and calibration processes. By developing targeted plans based on equipment characteristics, it can significantly improve operational stability and extend service life.

1、 Daily cleaning: prevent residue and blockage

Equipment surface cleaning

Use a clean cloth or compressed air to remove dust and stains from the surface of the equipment, avoiding corrosive material residue that can cause metal parts to rust.

Focus on cleaning up areas prone to material accumulation such as feed ports, discharge ports, and seals to prevent blockages in pipelines after material hardening.

Internal space cleaning

After daily shutdown, open the equipment maintenance door and use specialized tools to clean residual materials inside the drum screen, material collector, screw conveyor, etc.

Backblow the bag filter to ensure its permeability and prevent poor ventilation or dust leakage caused by blockage.

Key component protection

Avoid direct contact between water or damp cloth and electrical components such as motors and sensors during cleaning to prevent short circuits or signal interference.

For carbon steel material bodies, even if they are idle for a long time, they need to be regularly wiped with oil to prevent oxidation and rust.

2、 Lubrication and Maintenance: Reduce Wear and Malfunctions

Lubrication of transmission components

According to the equipment manual, regularly add lubricating oil (such as 3 # lithium grease) to transmission components such as bearings, gears, and chains to reduce friction and wear.

Lubrication cycle recommendation: bearings should be lubricated every 500 hours, chains every 200 hours, and the cycle should be shortened under high temperature or high load conditions.

Lubrication method selection

Use manual application or automatic lubrication system (such as centralized lubrication pump) to ensure even distribution of lubricating oil.

Avoid excessive lubrication causing oil contamination of materials, or insufficient lubrication causing overheating of components.

Lubrication record management

Establish a lubrication ledger to record lubrication time, location, oil type, and operators for easy traceability and optimization of maintenance plans.

3、 Tightening inspection: prevent vibration and displacement

Tightening of connectors

Before starting up daily, check whether the screws, nuts, flanges and other connecting parts are loose, and use a torque wrench to tighten them to the standard torque (such as the recommended torque for M12 bolts is 50-60N · m).

Focus on inspecting vibration sensitive parts such as motor bases, conveyor pipe supports, and dust collector fixing bolts.

Vibration source investigation

If there is abnormal vibration during the operation of the equipment, immediately stop the machine for inspection:

Is the balance block of the drum screen detached;

Whether the blades of the screw conveyor are deformed;

Is the motor belt loose or worn.

Application of anti loosening measures

For high-frequency vibration components (such as vibration motors), use anti loosening washers or thread glue reinforcement to reduce the risk of loosening.

4、 Calibration and debugging: ensuring accuracy and efficiency

Sensor calibration

Calibrate the weighing module with standard weights every month to ensure that the feeding error is ≤ ± 1%;

Clean the photoelectric sensor lens to prevent dust coverage from causing misjudgment (such as mistakenly believing that the material bag has been emptied).

Conveyor belt adjustment

Regularly check the tension of the conveyor belt and measure it with a tension gauge (if the belt tension is recommended to be 50-80N/cm) to avoid slipping or accelerated wear caused by excessive looseness.

Adjust the position of the roller group to ensure that the conveyor belt runs in the center and prevent material jamming caused by deviation.

Maintenance of bag breaking device

Check the wear of the cutting blade and replace it promptly when the blade thickness is ≤ 2mm;

Adjust the distance between the cutting blade and the material bag (recommended 3-5mm) to ensure that the bag is broken without damaging the drum screen.
