Pillow packaging machine is a continuous packaging machine with very strong packaging capacity and suitable for a variety of specifications for food and non-food packaging. It can not only be used for the packaging of unbranded packaging materials, but also can be used for high-speed packaging with reel materials pre-printed with trademark patterns. In packaging production, due to the error between the positioning color marks printed on the packaging material, the stretching of the packaging material and the influence of mechanical transmission and other factors, the predetermined sealing and cutting position on the packaging material may deviate from the correct position, resulting in errors. In order to eliminate errors and achieve the purpose of correct sealing and cutting, packaging design must consider the problem of automatic positioning. The solution to this problem is mostly to complete the design of a continuous photoelectric automatic positioning system based on the positioning mark of the packaging material. The continuous photoelectric positioning system is divided into forward and retreat type, brake type and two-transmission system synchronization type according to the error compensation working mode.

1. When the temperature is too high, the speed is too slow, and the outer layer of the film has poor heat resistance, the seal will show signs of scorching wrinkles. The repair method is to adjust the speed, lower the temperature, and replace the film material.

2. The knife holder is too high or too low, the packaging speed is too fast, and the push rod is not synchronized with the cutting knife, the cutting knife will cut on the product. The method of maintenance is to reduce the packaging speed, adjust the height of the end sealing part, and make the center of the sealing knife The middle position of the product height.

3. The color of the film color code is too light, the film drive is slippery, and the color code tracking is not turned on, the cutting position will deviate from the color code. At this time, the repair method is to refer to the pillow packaging machine manual and adjust its sensitivity; in the man-machine dialogue interface , Switch the tracking mode to "tracking cut".

4. The solid-state circuit breaker burns out, the temperature control meter is damaged, and the temperature meter cannot control the temperature when the thermocouple is damaged. The repair method is to replace the electric couple, replace the temperature control meter, and replace the heating element.

5. If the speed is too fast, the inner layer of the film has poor heat-sealability. When the temperature is too low, the seal will leak or become weak. The repair method is to slow down the speed, increase the temperature, and replace the film material.

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

And it should be noted that the induction aviation plug must be inserted before the power is turned on, and the screws must be tightened; metal covers and metal containers cannot be used, and the start button cannot be placed on a metal table, otherwise the machine will be damaged; Always touch the surface of the sensor head to check whether it is overheated. If you find that your hands are hot, stop heating and wait until it cools down before working. There will be high voltage in the pillow-type packaging body, and the bottom plate has electricity. Pay attention to it during maintenance to avoid personal danger.
