As the core equipment on the production line, the automatic checkweigher is widely used in the food, pharmaceutical, daily chemical and other industries. Its weighing accuracy and stability directly affect product quality and production efficiency. However, during long-term use, dust, residue or improper operation may cause equipment errors to increase or even malfunction. To help users extend the life of the equipment and ensure production safety, we have compiled the following cleaning and maintenance guide.
1. Daily cleaning steps: eliminate pollution and errors
(1). Power off operation to ensure safety
Be sure to turn off the power before cleaning to avoid the risk of electric shock, and prevent the cleaning liquid from penetrating into the circuit and causing a short circuit.
(2). Surface cleaning and disinfection
Use a soft cloth or sponge dipped in a neutral detergent (such as 75% alcohol or a special equipment cleaner) to wipe the surface of the scale, paying special attention to areas prone to dust accumulation such as the display screen and operation panel.
For food or pharmaceutical industry equipment, wipe with sterile water after cleaning and dry thoroughly to avoid chemical residues.
(3). Deep cleaning of conveyor belt and weighing area
Remove the conveyor belt (if removable) and remove the remaining debris, oil stains or powder. Compressed air can be used to blow the hidden gaps around the sensor.
Stubborn stains can be gently brushed with a soft brush. It is strictly forbidden to use steel wool or corrosive solvents (such as strong acids and alkalis).
(4). Sensor protection
Weighing sensors are precision components. Avoid direct spraying of liquids. If liquid splashes, immediately turn off the power and wipe gently with a dry, lint-free cloth.
2. Key points of regular maintenance: prevent failures and extend life
(1). Calibration check
It is recommended to calibrate the standard weight once a month to ensure that the weighing accuracy meets industry standards (such as ISO certification requirements).
If the temperature and humidity in the production environment fluctuate greatly, the calibration frequency needs to be increased.
(2). Inspection and lubrication of mechanical parts
Check whether the conveyor belt is loose or worn, and adjust or replace it in time.
For moving parts such as bearings and gears, add food-grade lubricants (applicable to the food industry) or industrial grease every quarter.
(3). Electrical system inspection
Regularly check whether the power cord and grounding device are intact to prevent leakage risks.
Clean the dust inside the control box to ensure the normal operation of the cooling fan.
(4). Environmental adaptability maintenance
Protective covers should be installed in high temperature, humid or dusty environments, and the integrity of the sealing strips should be checked regularly.
Avoid long-term exposure of the equipment to vibration sources to prevent the sensitivity of the sensor from decreasing.
Standardized cleaning and maintenance are the key to ensuring the efficient operation of the automatic checkweigher. Regular maintenance can not only reduce downtime losses, but also avoid the risk of product recalls due to weighing errors.
