Because of its different functions, structures and systems, three-dimensional guard sanitary napkin equipment is complex and has different characteristics. The contents and rules of protection also have their own characteristics. According to the type, type and actual use of the machine, and the requirements of the machine operation manual, necessary periodic and hierarchical protection standards shall be formulated and formulated. The following are the key precautions for daily maintenance of three-dimensional guard sanitary napkin machine?
Strictly following the three-dimensional guard sanitary napkin equipment operation procedures can effectively avoid equipment abnormalities, establish perfect daily protection standards, extend the service life of equipment and avoid production accidents. Oil mist, dust and even metal powder usually exist in the air of the processing workshop. Once it falls on the circuit board or electronic equipment of the equipment system, it is easy to reduce the insulation resistance between components, and even damage components and circuit boards. In summer, some users open the equipment cabinet door for heat dissipation, which causes long-term overload of the equipment system. This is a very undesirable method, which will eventually accelerate the damage of the equipment system. Check whether the cooling fan on the equipment cabinet works normally. Check whether the air duct filter is blocked every six months or every quarter. For example, there is too much dust accumulated on the filter screen, which is not sorted out in time, and the temperature in the equipment cabinet is too high. Generally, a charging battery protection circuit is provided for the storage device in the device system to ensure that the contents of the storage device can be maintained in case of power failure. Under normal circumstances, even if there is no fault, it should be replaced once a year to ensure the normal operation of the system.
Regularly adjust the tightness of the spindle drive belt of three-dimensional guard sanitary napkin equipment to avoid rotation loss caused by belt sliding. Check the smooth thermostatic oil tank of the spindle, adjust the temperature scale, add oil in time, clean the filter. Long term use of the spindle clamping equipment will produce clearance, affect clamping, and timely adjust the displacement of the hydraulic cylinder piston. Regularly check and adjust the axial clearance of the screw pair to ensure the accuracy and axial stiffness of the reverse drive, regularly check whether the connection between the screw and the bed is loose, and timely replace the screw protection device to avoid the entry of dust or debris. It is strictly prohibited to put overweight or too long tools into the tool magazine to avoid tool falling off or collision with workpiece when replacing tools; Frequently check whether the parts of the tool magazine are correct and whether the tool axis returns to the original point in place, and adjust it in time; During start-up, the tool magazine and manipulator shall idle, and check whether the operation of each component is normal, especially whether the stroke switch and solenoid valve are normal; Check whether the tool lock on the manipulator is reliable. In case of any abnormality, it shall be handled in time. Regularly clean or replace filters or sub filters of various smooth, hydraulic and pneumatic systems; Regularly check the oil quality of the hydraulic system and replace the hydraulic oil; Clean the foreign matters in the oil circuit and nozzle of the oil supply system regularly. In case of deposition, condensation, deterioration and other problems, the cutting oil shall be replaced in time. Regularly check and correct the mechanical accuracy of the slow level of the machine. There are two methods to correct mechanical accuracy: soft correction and hard correction.
When three-dimensional guard sanitary napkin equipment fails, it is necessary to patiently analyze the specific situation, find out the relevant fault points and handle them to restore the machine to normal.
