The daily maintenance of the semi - automatic powder weighing filling machine is crucial for ensuring stable equipment performance, extending its service life, and guaranteeing metering accuracy. This maintenance involves a diverse range of tasks, with specific procedures designed for different key components.
I. Daily Maintenance Tasks
(I) Cleaning Procedures
After production, the primary task is to conduct a comprehensive cleaning of the equipment. Utilize a dry soft brush or a vacuum cleaner to carefully remove residual powder from both the surface and the interior of the machine. Particular attention should be paid to the corners, crevices of the filling machine, and the interfaces of the powder delivery pipelines, as these areas are prone to powder accumulation and caking. For the equipment casing and operation panel, wipe them with a clean damp cloth to eliminate surface stains. However, it is essential to prevent moisture from infiltrating the equipment, as this could potentially lead to electrical malfunctions. In the case of filling machines used for handling food, pharmaceuticals, and other products, it is necessary to use cleaning agents that meet hygiene standards for thorough cleaning and disinfection, thereby ensuring product safety.
(II) Inspection Procedures
Operation Status Inspection：Before starting the equipment and during its operation, closely monitor the equipment's operational condition. Keep a close watch for any abnormal vibrations or noises generated during the operation. If the filling machine shows significant shaking or produces abnormal sounds during the weighing or filling processes, immediately stop the operation. Conduct a prompt inspection, analyze the root cause, and take timely corrective actions to prevent the problem from worsening.
Connection Part Inspection：Examine the tightness of the connecting bolts and nuts at all joints of the equipment, including the connection between the weighing platform and the bracket, as well as the connection between the filling head and the conveying pipeline. For frequently moving parts, such as the filling head lifting device and the powder feed port opening - and - closing mechanism, increase the inspection frequency. Tighten any loose components immediately to prevent unstable equipment operation or safety hazards caused by loose connections.
Electrical System Inspection：Inspect the electrical circuits within the control cabinet for signs of damage or aging. Verify the operational status of electrical components, such as relays, contactors, and display screens. Ensure that the electrical system is properly grounded to prevent electrical leakage accidents. At the same time, check whether the display on the equipment control panel is functioning normally and whether the operating components, such as buttons and switches, are sensitive and reliable.
(III) Lubrication Procedures
In accordance with the equipment instruction manual, regularly apply lubricating oil or grease to the transmission components, bearings, and other parts that require lubrication. For example, lubricate the transmission chain, gears, guide rails, etc., to ensure smooth movement and minimize wear. When lubricating, carefully control the amount of lubricant to avoid over - or under - application. Additionally, maintain the cleanliness of the lubricated parts to prevent impurities from impairing the lubrication effect.
II. Maintenance Key Points for Critical Components
(I) Weighing Sensor
Daily Cleaning：The weighing sensor should be kept clean to prevent powder from adhering to its surface and force - bearing parts. When cleaning, use a clean soft cloth and wipe gently. Under no circumstances should hard objects be used to scratch or impact the sensor forcefully, as this could damage its sensitive components.
Overload Prevention：The weighing sensor has a rated weighing range, and it is strictly prohibited to exceed this range during operation, as doing so may cause damage to the sensor or reduce its accuracy. When placing materials on the sensor, handle them gently to avoid applying excessive impact forces.
Regular Calibration：To ensure weighing accuracy, the weighing sensor requires regular calibration. Standard weights can be used for this purpose. If a significant deviation is detected between the measured value and the standard value, make timely adjustments or seek professional assistance for calibration and maintenance.
Moisture and Corrosion Protection：Some weighing sensors are highly sensitive to environmental humidity and corrosive substances. Ensure that the sensor operates in a dry environment. When used for filling corrosive powders, implement protective measures, such as installing a protective cover, to prevent corrosive substances from coming into contact with the sensor and thus safeguarding its performance and lifespan.
(II) Filling Head
Cleaning and Unclogging：As a component in direct contact with the powder, the filling head must be thoroughly cleaned after each use. Disassemble the filling head and remove any residual powder inside to prevent it from drying and blocking the discharge port. For small channels and orifices, use specialized cleaning tools to ensure unobstructed filling.
Wear Inspection：Regularly inspect the filling head for wear and tear. Check whether the discharge port is deformed or worn and whether the seals are aged or damaged. If severe wear or poor sealing is detected, replace the corresponding parts promptly to avoid issues such as powder leakage and inaccurate filling volume during the filling process.
Filling Parameter Adjustment：Adjust the relevant parameters of the filling head, such as the filling speed and discharge port size, in a timely manner according to the different characteristics of the powder and filling requirements. During the adjustment process, strictly adhere to the operating specifications to prevent improper parameter settings from affecting the filling effect and the normal operation of the equipment.
