Flow wrap machine is a very widely used packaging equipment, and the operation is also very simple. But in the process of work, there are often some problems that bring trouble to the production. Some problems need to be solved by contacting the manufacturer, and some problems can be solved by yourself. We list some flow wrap machine troubleshooting here.
1. When the temperature is too high, the speed is too slow, and the heat resistance of the outer layer of the packaging film is poor, the seal will appear scorched and wrinkled.
The maintenance method is to adjust the speed, lower the temperature, and replace the film material.
2. The knife seat is too high or too low, the packing speed is too fast, and the knife will cut on the product when the push rod and the knife are not synchronized.
The maintenance method is to reduce the packaging speed and adjust the height of the end sealing parts so that the center of the sealing knife is in the middle of the product height.
3. The color of the film color mark is too light, the film drive is slippery, and the cutting position will deviate from the color mark when the color mark tracking is not turned on.
The maintenance method is to refer to the manual of the packaging machine and adjust its sensitivity; in the man-machine dialogue interface, switch the tracking mode to “tracking cut”.
4. The solid-state circuit breaker is burned out, the temperature control meter is damaged, and the thermometer cannot control the temperature when the thermocouple is damaged.
The maintenance method is to replace the thermocouple, replace the temperature control meter, and replace the heating element.
5. The speed is too fast, and the inner layer of the packaging film has poor heat sealing performance. When the temperature is too low, the sealing will be leaked or not firm.
The method of maintenance is to slow down the speed, increase the temperature, and replace the material of the film.
6. The air pressure is wrong, the cylinder swing rod is loose, the heating temperature is low, and the heat sealing roller is not parallel to the transmission roller, which will cause poor heat sealing.
The maintenance method is to adjust the parallelism, adjust the temperature and air pressure to tighten it. And it should be noted that the induction aviation plug must be inserted before the power is turned on, and the screws must be locked; metal lids and metal containers cannot be used, nor can they be placed on a metal table to press the start button, otherwise the machine will be damaged.
