Fault diagnosis and daily maintenance of automatic sanitary napkin machinery
With the development of society and the advancement of science and technology, the manufacturing industry is constantly developing. As the main processing equipment, fully automatic sanitary napkin machinery has been widely used. Because the staff do not pay attention to the maintenance work of the equipment, the failure rate of the equipment continues to increase. Next, let me tell you about the fault diagnosis and daily maintenance methods of automatic sanitary napkin equipment.
1. Fully automatic sanitary napkin mechanical fault diagnosis
(1) Check and troubleshoot directly. In the troubleshooting of automatic sanitary napkin machinery, the direct inspection method is the most direct and effective method. It is mainly realized through the staff's visual and tactile senses, but it is difficult to accurately find out the root cause of the electrical failure of the machinery and equipment.
(2) Interface inspection method. The application of machine technology in equipment production is mainly realized by programmable logic controllers. Therefore, ensuring the accuracy and timeliness of data signal transmission is very important for the efficient operation of the entire device. Once there is a problem with the interface of the data transmission signal, it will cause problems such as data transmission error and data loss, which will make the control system of the machine equipment disorder. Therefore, relevant technical personnel must always monitor whether there is any abnormality in the working status of the interface display lights, and eliminate potential safety hazards in time.
(3) Use testing equipment to check. When inspecting machinery and equipment, it will be applied to various types of instruments, so the above two methods can be used to troubleshoot before inspection, and then select the instrument for the problem. For example, when checking the power supply, you can use an electrical meter to measure the voltage value, and then compare it with the normal data to check whether the equipment is faulty.
(4) Adjust working parameter method. Compared with traditional equipment, the production methods of automatic sanitary napkin machinery are more diversified, which can meet the production needs of different products. This also puts forward higher requirements for the professional technical level of operators, and requires them to be able to produce in time according to production needs. Adjust the relevant machine parameters to prevent the electrical failure of the equipment due to the mismatch between the data parameters and the production requirements during the production process.
(5) Improve the alarm system. During the use of machinery and equipment, some accessories will wear out due to long-term use. If they are not replaced in time, electrical failures will occur, which will increase the work difficulty of maintenance personnel. Therefore, improving the equipment alarm system plays a role that cannot be ignored, whether it is for the safety of the equipment or for ensuring the efficiency of the equipment. Common alarm devices include two kinds of signal lights flashing and sound prompts. Their application in machinery and equipment can greatly simplify the workflow of equipment maintenance and improve the effectiveness of the application of equipment electrical maintenance technology.
(6) Ensure the timeliness of parts replacement. In the process of equipment production, accessories are prone to wear and tear, and some equipment accessories contain relatively complex circuits, so it is difficult to detect the location of the failure in a short time. Therefore, ensuring the timeliness of parts replacement can not only reduce the possibility of electrical failure of the equipment, but also ensure the working efficiency of the equipment to the greatest extent. After replacing the parts, the staff should not discard the parts directly, but should check whether there is any problem with the parts and repair them in time to reduce costs while ensuring production safety.
2. Maintenance of automatic sanitary napkin mechanical parts
(1) Maintenance of the main drive chain. Regularly adjust the tightness of the spindle drive belt to prevent loss of rotation caused by the belt; check the constant temperature mailbox for spindle lubrication, adjust the temperature range, replenish the oil in time, and clean and filter it; the tool clamping device in the spindle is used for a long time. , there will be a gap, which will affect the clamping of the tool. It is necessary to adjust the displacement of the hydraulic cylinder piston in time.
(2) Hydraulic and pneumatic system maintenance. Regularly clean or replace the filters or sub-filters of each lubrication, hydraulic, and pneumatic systems; regularly conduct oil quality inspections and replace hydraulic oil in the hydraulic system; regularly drain water from the sub-filters of the pneumatic system
(3) Equipment precision maintenance. Regularly check and correct the mechanical level and precision of fully automatic sanitary napkins. There are two kinds of correction methods for mechanical precision: soft and hard. The soft method is through system parameter compensation, such as screw backlash compensation, coordinate positioning, precision fixed point compensation, equipment return to reference point position correction, etc.; the hard method is generally carried out during equipment overhaul, such as guide rail repair scraping, ball The screw nut pair is pre-tightened to adjust the backlash, etc.
In mechanical production and construction, mechanical equipment is an indispensable part, which provides a strong guarantee for the development of enterprises and the country. However, automatic sanitary napkin machinery will suffer friction loss after long-term work, and it needs to be repaired and maintained in a timely manner. Otherwise, there will be situations that affect production and use, resulting in greater economic losses.
