How to maintain and care for the kneading machine

I. Daily maintenance
1. Cleaning
After each use, the residual materials inside and outside the kneading machine should be cleaned in time. You can use a soft cloth or brush to wipe it. For stubborn stains, you can use appropriate detergents, but avoid using highly corrosive detergents to avoid damaging the surface of the equipment. For example, for kneading machines in the food industry, you can use food-grade detergents to clean them to ensure that the equipment meets hygiene standards.
Clean the gap between the stirring blades and the container wall to prevent material accumulation from affecting the stirring effect. You can use special tools or compressed air to clean it to ensure that the gap is clean and free of debris.
2. Check the seal
Regularly check the seals of the kneading machine, such as shaft seals, end cover seals, etc., to ensure that they are intact. Damage to the seals will cause material leakage, affect the production environment and product quality, and also accelerate the wear of the equipment. For example, check whether the shaft seal is worn or aged, and if there is a problem, it should be replaced in time.
Check whether the seal is installed correctly and ensure that the seal fits tightly with the shaft or end cover without looseness. Sealant or gasket can be used for auxiliary sealing to improve the sealing effect.
3. Lubrication
Regularly lubricate the transmission parts of the kneading machine, such as reducers, bearings, etc. Select appropriate lubricating oil or grease according to the instruction manual of the equipment, and add it according to the prescribed time and method. For example, reducers are usually lubricated with industrial gear oil, and bearings can be lubricated with grease.
Pay attention to the quality and cleanliness of the lubricating oil or grease, and avoid using expired or contaminated lubricants. Check the level and quality of the lubricating oil or grease regularly, and replace it in time if necessary.
2. Regular maintenance
1. Check the electrical system
Regularly check the electrical system of the kneading machine, including motors, controllers, wires, etc. Check whether the motor is running normally, whether there is abnormal noise and heating. For example, check whether the bearings of the motor are worn, and if there are any problems, they should be replaced in time.
Check whether the functions of the controller are normal, such as temperature control, speed control, etc. Ensure that the parameters of the controller are set correctly and meet the production process requirements. For example, check whether the sensor of the temperature controller is accurate, and if there are any problems, they should be calibrated or replaced in time.
Check whether the wires are damaged or aged, and if there are any problems, they should be replaced in time. Ensure the safety and reliability of the electrical system to avoid electrical accidents.
2. Check mechanical parts
Regularly check the mechanical parts of the kneading machine, such as stirring blades, transmission devices, frames, etc. Check whether the stirring blades are worn or deformed. If there are any problems, they should be replaced in time. For example, for severely worn stirring blades, surfacing repairs or new blades can be performed.
Check whether the chains, belts, gears, etc. of the transmission device are loose or worn. If there are any problems, they should be adjusted or replaced in time. For example, check whether the tension of the chain is appropriate and adjust it if necessary.
Check whether the frame is deformed or corroded. If there are any problems, they should be repaired or replaced in time. Ensure the stability and reliability of mechanical parts and the normal operation of the equipment.
3. Calibration and debugging
Regularly calibrate and debug the kneading machine to ensure that the various parameters of the equipment meet the production process requirements. For example, calibrate temperature sensors, pressure sensors, etc. to ensure that the measurement data is accurate and reliable.
Debug parameters such as stirring speed and temperature control to ensure the operation effect of the equipment. Appropriate adjustments and optimizations can be made according to different materials and production process requirements.
3. Precautions
1. Safe operation
When performing maintenance and servicing work, first cut off the power supply and hang warning signs such as "No Closing" to ensure the safety of the operator. For example, when inspecting the electrical system, cut off the power supply first to avoid electric shock accidents.
Maintenance and servicing work should be carried out by professionals, and the operator should be familiar with the structure and performance of the equipment and master the correct maintenance and servicing methods. For example, when inspecting mechanical parts, it should be carried out by professional mechanical maintenance personnel to avoid equipment damage due to improper operation.
2. Spare parts management
Establish a spare parts management system, regularly check the inventory of spare parts, and ensure sufficient supply of spare parts. For example, for wearing parts such as seals and stirring blades, spare parts should be prepared in advance so that they can be replaced in time when needed.
Classify and manage spare parts, mark and record them well, and ensure the quality and traceability of spare parts. For example, for important spare parts, they can be managed by number, and their purchase date, manufacturer, specifications and models can be recorded.
3. Training and records
Regularly train operators to improve their maintenance and servicing awareness and skills. For example, operators can be organized to participate in equipment maintenance and maintenance training courses to learn the correct operation methods and maintenance skills.
Establish maintenance and maintenance records to record the maintenance and maintenance of the equipment, including maintenance time, maintenance content, replaced parts, etc. For example, after each maintenance and maintenance work, the maintenance record should be filled in in time to facilitate tracking and analysis of the operation of the equipment.
