How to maintain shrink wrapping machine?


The continuous development of science and technology also promotes the continuous improvement and growth of the packaging industry. For the high-efficiency and long-running packaging equipment of shrink wrapping machine, how should personnel maintain it so that it can serve the enterprise well? The following SICIAUTO summarizes a few points.


The heat shrinking wrapping machine should be used in an environment where the temperature is -10°C-50°C, the relative humidity is not more than 85%, and there is no corrosive gas in the surrounding air, no dust, and no explosive danger.



In order to ensure the normal operation of the vacuum pump by the shrinking machine, the vacuum pump motor is not allowed to reverse. The oil level should be checked frequently. The normal oil level is 1/2-3/4 of the oil window (can not exceed). When there is moisture in the vacuum pump or the color of the oil changes When it is dark, the new oil should be replaced at this time (generally, it should be replaced once every one or two months after continuous work, and 1# vacuum gasoline or 30# gasoline or engine oil can also be used).



The impurity filter should be disassembled and washed frequently (usually once every 1-2 months, such as packaging debris-like objects, the cleaning time should be shortened).



After working continuously for 2-3 months, the back cover 30 should be opened to add lubricating oil to the sliding parts and switch bumps, and the connecting activities on the heating rod should be lubricated according to the usage.



Regularly check the decompression, filtration and oil mist triple parts 24 to ensure that there is oil (sewing machine oil) in the oil mist and oil cup, and there is no water in the filter cup.



The heating strip and the silicone strip should be kept clean, and no foreign matter should be stuck, so as not to affect the sealing quality.



On the heating rod, the second layer of paste under the heating sheet plays an insulating role. When it is damaged, it should be replaced in time to avoid short circuit.



The working air source and inflation air source are provided by the user. The working pressure of the shrinking machine has been set to 0.3MPa, which is more appropriate. Do not adjust it too much unless there are special circumstances.



The shrinking machine is not allowed to be tilted and impacted during the handling process, and it is not allowed to be tipped for handling.



There must be a reliable grounding device during installation.



It is strictly forbidden to put your hand under the heating rod to prevent injury, and immediately cut off the power supply in case of emergency.



When working, first ventilate and then power on, and when shutting down, first power off and then cut off.



The shrinking machine is a high-power machine, and the power supply must be reliably grounded and properly connected according to the instructions;



When the shrinking machine is used continuously for more than three months, the temperature-resistant wires of the shrinking tunnel should be checked and replaced as appropriate according to their aging degree;



Generally, when the machine is working, the operator's palm and other parts are not allowed to contact the operating parts of the machine, especially the temperature inside the shrink tunnel is extremely high, which is easy to burn;



When the packaging is over, be sure to turn off the heating switch first, let the conveying motor and the fan motor run for about 10 minutes, and then cut off the entire power supply.
