Precautions for the use of four-sided sealing wipes packaging machine

China's packaging machinery began20Century70End of the decade. The Beijing Institute of Commercial Machinery completed the manufacture of China's first packaging machinery after studying Japanese packaging machinery. After20After years of development, China's packaging machinery 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. Part of the packaging machinery to fill the domestic blank, the basic can meet the domestic market demand, some products export. But at this stage, the export value of China's packaging machinery is less than the total output value.5%, the value of imports is roughly equal to the total output value, which is far from developed countries. In the process of the rapid development of the machinery industry, it is inevitable that there will be some mechanical failures, common failures and maintenance methods of the four-sided sealing wipes packaging machine.

1If the speed of the four-side sealing wipes packaging machine is too fast, the heat sealing of the inner layer of the coating is poor. If the temperature is too low, the seal will leak or be unstable. The maintenance method is to slow down, increase the temperature, and change the material of the film.

24. The solid-state circuit breaker of the four-side sealing wipes packaging machine is burnt out, the temperature control meter is damaged, and the thermocouple is damaged. The thermometer cannot control the temperature. The maintenance method is to replace the coupling, temperature control meter and heating element.

3The color code of the film is too light, the film driver slips, and the cutting position will deviate from the color code if the color code tracking is not turned on. The maintenance method at this time is to refer to the packaging machine manual to adjust its sensitivity; in the man-machine dialogue interface, switch the tracking mode to the "tracking switch".

4, The knife seat is too high or too low, the packaging speed is too fast, when the push rod and the knife are not in step, the knife will cut on the product. The maintenance method is to reduce the packaging speed and adjust the height of the end sealing part so that the center of the sealing knife is in the middle of the product height.

5When the temperature of the four-sided sealing wipes packaging machine is too high, the speed is too slow, and the heat resistance of the outer layer of the envelope is poor, there will be wrinkles at the sealing. Maintenance method is to accelerate, cooling, change the film material.

6If the air pressure is wrong, the cylinder swing rod is loose, the heating temperature is low, and the hot pressure roller and the driving roller are not parallel, poor heat sealing will occur. The maintenance method is to adjust the parallelism, adjust the temperature and air pressure to make it tight.

Note: Before turning on the power, you must first insert the induction aviation plug and lock the screws; you cannot use metal covers and metal containers, nor can you put them on a metal table, press the start button, otherwise it will damage the machine; during work, often touch the sensor Head surface, check whether it is overheated. If it is found to be overheated, stop heating after cooling; there will be high pressure in the pillow body of the four-sided sealing wipes packaging machine, and the bottom plate will be charged. Be careful when repairing to avoid personal danger!
