With the development of society and the advancement of technology, the manufacturing industry is continuously evolving. Fully automatic baby diaper machines, as primary processing equipment, have been widely utilized. However, due to the negligence of maintenance by staff, the failure rate of equipment continues to rise. In the following, we will discuss the diagnosis of faults in fully automatic baby diaper equipment and methods for routine maintenance.

Fault Diagnosis of Fully Automatic Baby Diaper Machinery

(1) Direct Inspection for Fault Exclusion: In the troubleshooting of fully automatic baby diaper machinery, direct inspection is the most direct and effective method. It is mainly achieved through the visual and tactile senses of the staff, but it is difficult to accurately identify the root cause of electrical faults that cause the machine to malfunction.

(2) Interface Inspection Method: The application of machine technology in equipment production mainly relies on programmable logic controllers (PLCs). Therefore, ensuring the accuracy and timeliness of data signal transmission is crucial for the efficient operation of the entire equipment. Once there is a problem with the interface of data transmission signals, it will cause issues such as data transmission errors and loss, disrupting the control system of the machine. Therefore, relevant technicians must always monitor the working status of the interface indicator lights for any abnormalities and promptly eliminate safety hazards.

(3) Use of Testing Instruments:

Various types of instruments are applied when inspecting machine equipment, so before inspection, the above two methods can be used for fault exclusion, and then instruments can be selected based on the specific problem. For example, when inspecting the power supply, an electrician's instrument can be used to measure the voltage value, and then compare it with normal data to check for equipment faults.

(4) Adjustment of Working Parameters Method:

Compared to traditional equipment, the production methods of fully automatic baby diaper machinery are more diverse, capable of meeting the production needs of different products. This also places higher demands on the professional technical level of operators, requiring them to promptly adjust relevant machine parameters according to production needs. This prevents electrical faults in the equipment during production due to mismatched data parameters and production requirements.

(5) Improvement of Alarm Systems:

During the use of machine equipment, some components may experience wear and tear due to prolonged use. Failure to replace them in a timely manner can lead to electrical faults, increasing the difficulty for maintenance personnel. Therefore, enhancing the equipment's alarm system plays an essential role in both ensuring equipment safety and maintaining operational efficiency. Common alarm devices include flashing signal lights and audible alerts. Their application in machine equipment greatly simplifies the workflow of equipment maintenance, enhancing the effectiveness of electrical maintenance techniques.

(6) Ensuring Timely Replacement of Components:

Components are prone to wear during equipment production, and some of them contain complex circuits, making it difficult to detect faults in a short time. Therefore, ensuring the timely replacement of components not only reduces the possibility of electrical faults in equipment but also maximizes operational efficiency. After replacing components, personnel should not discard them immediately but instead check for any issues and promptly repair them to ensure production safety while minimizing cost expenditures.

Maintenance of Components in Fully Automatic Baby Diaper Machinery

(1) Maintenance of Main Drive Chain:

Regularly adjust the tightness of the main shaft drive belt to prevent slippage caused by belt loosening.
Inspect the constant temperature oil tank and adjust the temperature range for main shaft lubrication. Replenish oil in a timely manner and clean the filter.
After prolonged use of the tool clamping device in the main shaft, clearances may develop, affecting tool clamping. Adjust the displacement of the hydraulic cylinder piston promptly.

(2) Maintenance of Hydraulic and Pneumatic Systems:
Regularly clean or replace the filters or filter screens in the lubrication, hydraulic, and pneumatic systems.
Conduct periodic oil quality tests and replace hydraulic oil accordingly.
Periodically drain water from the pneumatic system filter.

(3) Maintenance of Equipment Precision:
Conduct regular inspections and calibration of the horizontal and mechanical accuracy of the fully automatic baby diaper machinery. Calibration methods for mechanical accuracy include both soft and hard approaches.
Soft methods involve compensating system parameters, such as backlash compensation of the screw, coordinate positioning, precision spot compensation, and calibration of the equipment's return to reference point position.
Hard methods are typically performed during major equipment overhauls and may include tasks like rail scraping and adjustment of backlash in ball screw nut pairs.
