China's packaging machinery started late, starting in the 1970s, after the Beijing Institute of Commercial Machinery researched Japanese packaging machinery, it completed the manufacture of China's first packaging machine. After more than 20 years of development, China Packaging Machinery has It has become one of the top ten industries in the machinery industry, providing a strong guarantee for the rapid development of China's packaging industry. Some packaging machinery has filled the domestic gap and has been able to basically meet the needs of the domestic market. Some products are also exported. However, at this stage, the export value of China's packaging machinery is still less than 5% of the total output value, but the import value is almost equal to the total output value, which is far from the developed countries. In the fast-growing machinery industry, some mechanical failures will occur, and the common faults and maintenance methods of pillow packaging machines.
First, the speed is too fast, the inner seal of the envelope is poorly sealed. When the temperature is too low, the seal may leak or be weak. The maintenance method is to slow down the speed, raise the temperature, and replace the material of the film.
Second, the solid state breaker is burned out, the temperature control table is damaged, and the temperature gauge cannot control the temperature when the thermocouple is damaged. The repair method is to replace the power control couple, replace the temperature control table, and replace the heating element.
Third, the color code of the film is too light, the film drive is slippery, and when the color code tracking is not turned on, the cut position will deviate from the color mark. At this time, the repair method is to adjust the sensitivity of the package according to the packaging machine manual; in the human-machine dialogue interface, Switch the tracking mode to "Tracking Cut".
Fourth, the knife seat is too high or too low, the packaging speed is too fast, when the push rod and the cutter are not synchronized, the cutter will cut the product on the product to reduce the packaging speed, adjust the height of the end seal part, so that the center of the sealing knife is The middle position of the product height.
5. If the temperature is too high and the speed is too slow, when the heat resistance of the outer layer of the coating is poor, the trace of the wrinkles will appear on the seal. The maintenance method is to adjust the speed, reduce the temperature, and replace the film material.
Sixth, the air pressure is wrong, the cylinder pendulum rod is loose, the heating temperature is low, the heat sealing roller and the driving roller are not parallel, the heat sealing will be bad. The maintenance method is to adjust the parallelism and adjust the temperature and air pressure to make it fast.
Note: Before inserting the power supply, you must insert the induction air plug and lock the screw; you can not use metal cover and metal container, and you can't put the start button on the metal table, otherwise it will damage the machine; you should always touch the sensor during work. Check the surface of the head to check if it is overheated. If it is found that the hot hand should stop heating, it should work after cooling; there will be high pressure in the pillow packaging body, and the bottom plate has electricity. Pay attention when repairing, so as to avoid personal danger!
