China's packaging machinery started late, starting in the 1970s, the Beijing Municipal Commercial Machinery Research Institute in the study of Japanese packaging machinery, completed the manufacture of China's first packaging machine, after more than 20 years of development, China's packaging machinery has become one of the top ten industries in the machinery industry, the rapid development of China's packaging industry to provide a strong guarantee, some packaging machinery to fill the domestic blank, has been able to basically meet the The domestic market demand, some products and exports. But at this stage, China's packaging machinery exports are less than 5% of the total output value, imports are roughly the same as the total output value, and developed countries are very far away. In the rapid development of the machinery industry will inevitably have some mechanical failure, pillow packaging machine common failures and repair methods.
First, the speed is too fast, the inner layer of the package film heat sealability is poor, the temperature is too low when the seal will appear leaky seal or not firm, the method of repair is to slow down the speed, adjust up the temperature, replace the film material.
Secondly, the solid state disconnector is burnt out, the temperature control table is damaged, the temperature table cannot control the temperature when the thermocouple is damaged, the method of repair is to replace the executive electric couples, replace the temperature control table and replace the heating body.
Third, the colour of the film colour code is too light, film drive slippage, colour code tracking is not open when the cut-off position deviates from the colour code, then the maintenance method is to refer to the packaging machine manual, adjust its sensitivity; in the man-machine interface, the tracking mode to switch to "tracking cut".
Fourth, the knife seat is too high or too low, packaging speed is too fast, push rod and cutter is not synchronized, the cutter will cut in the product repair method is to reduce the packaging speed, adjust the end seal components high and low, so that the seal knife centre in the middle of the product height.
Five, the temperature is too high, the speed is too slow, the outer layer of the film heat resistance is poor, the seal will appear scorched traces of wrinkles repair method is to adjust the speed, reduce the temperature, replace the film material.
Sixth, the air pressure is not right, the cylinder pendulum is loose, the heating temperature is low, the hot press roller and the transmission roller are not parallel when there will be poor heat sealing, the repair method is to adjust the parallelism, adjust the temperature and air pressure to make it tight.
Note: the induction air plug must be inserted before the power is passed, and the screws are locked; the metal loading cover and metal container cannot be used, and the start button cannot be pressed on the metal table, otherwise the machine will be damaged; the surface of the induction head should be touched frequently during work to check whether it is overheated, if it is found to be hot, the heating should be stopped and work should be done after cooling; there will be high voltage in the body of the pillow packaging machine, and the bottom plate has electricity, so the maintenance must be Be careful to avoid personal danger!
