The daily maintenance of the fully automatic paste filling production line is crucial for maintaining optimal equipment performance, extending its service life, and ensuring consistent filling quality. The following details the specific maintenance procedures:​

I. Cleaning Work​

(I) Equipment Surface Cleaning​

Upon completion of daily production, promptly wipe the equipment surface using a clean cloth and specialized cleaning agents to remove residual paste, oil stains, and dust. For tenacious stains, gently scrape them off with a soft - edged scraper before thorough cleaning. Pay particular attention to hard - to - reach areas such as the corners, crevices of the equipment, regions around the filling head, and gaps within the transmission chain. This meticulous cleaning prevents paste hardening and debris accumulation, safeguarding the equipment's normal operation and appearance.​

(II) Filling System Cleaning​

As a critical component in direct contact with the paste, the filling head requires intensive cleaning. After disassembly, immerse it in a dedicated cleaning solution and use a soft brush to gently scrub the internal channels and discharge ports, ensuring no paste residue remains to cause blockages. For the pipeline conveying system, conduct a cyclic flushing with the cleaning solution. When necessary, utilize compressed air to dry the interior of the pipelines, thereby preventing residual liquid from fostering bacterial growth or compromising the quality of subsequent paste filling.​

(III) Cleaning of Auxiliary Equipment​

Clean the surfaces of auxiliary equipment, including capping machines and labeling machines, to remove dust and debris. Simultaneously, carefully inspect and clear the bottle cap tracks of capping machines and the label - conveying channels of labeling machines. This preventive measure averts potential malfunctions caused by foreign objects entering the equipment.​

II. Inspection Work​

(I) Operation Status Inspection​

Closely monitor the equipment's operation both before startup and during the production process. Check for smooth operation of all components and listen for any abnormal vibrations or noises. In the event that the filling machine exhibits significant shaking during filling or the capping machine emits unusual sounds during capping, immediately halt the equipment. Conduct a prompt inspection, analyze the root cause, and implement timely corrective actions.​

(II) Connection Part Inspection​

Examine the tightness of connecting bolts and nuts at all joints of the equipment, including the connection between the filling machine and its support frame, as well as the linkages within the transmission mechanism. Pay extra attention to frequently moving parts, such as the filling head lifting device and the labeling machine's swinging mechanism. Tighten any loose components promptly to prevent operational instability and potential safety hazards.​

(III) Electrical System Inspection​

Inspect the electrical circuits within the control cabinet for signs of damage or aging. Verify the operational status of electrical components, including relays, contactors, and sensors. Ensure the electrical system is properly grounded to prevent electrical leakage. Additionally, check the normal display of the equipment control panel and the sensitivity and reliability of operational components, such as buttons and switches.​

(IV) Filling Accuracy Inspection​

Regularly sample filled products and measure the filling volume using high - precision weighing instruments. Compare the measured values with the standard range. If any inaccuracies are detected, promptly adjust the metering parameters of the filling machine. Additionally, check the working conditions of related components, such as metering pumps and flow meters, to guarantee consistent filling accuracy.​

III. Lubrication Work​

In accordance with the equipment manual, regularly apply lubricating oil or grease to transmission components, bearings, and other lubrication - required parts. Lubricate components such as transmission chains, gears, guide rails, and lead screws to ensure smooth movement and minimize wear. When lubricating, control the amount of lubricant precisely to avoid over - or under - application. Maintain the cleanliness of lubricated areas to prevent impurities from degrading the lubrication effect.​

IV. Component Maintenance​

(I) Filling Head Maintenance​

Beyond routine cleaning, regularly assess the wear and tear of the filling head. Examine the discharge port for deformation or wear and check the seals for signs of aging or damage. Replace any severely worn or leaky components promptly to prevent paste leakage during filling, thereby ensuring both filling accuracy and product quality.​

(II) Transmission Mechanism Maintenance​

Check the tension of transmission belts and chains, adjusting them as needed to maintain optimal tension. Inspect belts and chains for signs of wear, cracks, or other damages, and replace them promptly if necessary. For gear - based transmission mechanisms, evaluate gear meshing, check the tooth surfaces for wear or pitting, and perform regular lubrication and maintenance.​

(III) Sensor Maintenance​

Sensors play a pivotal role in automated control systems. Regularly check their sensitivity and accuracy. Clean the sensing surfaces of sensors to eliminate dust and stains that could interfere with their performance. Conduct simulation tests to verify the normal signal output of proximity sensors, photoelectric sensors, and other types of sensors. Calibrate or replace sensors immediately if any abnormalities are detected.​
