Analysis Of Common Faults Of Small Automatic Sealing Machine

Small automatic sealers are fast-selling and fast-opening in the food packaging industry using fast and tight seals. It is impossible to say the efficiency and speed. The quality of the seal is also very tight. The finished product rate is as high as 99%. This equipment requires regular maintenance. If it is not frequently maintained, it will cause some machine failures and reduce the future of the equipment. Service life, when the equipment fails during production, we must focus on analysis and find solutions, the following common failure analysis is for reference only!

1.The pressure of the cold rubber roller of the sealing machine is not suitable

There is one cold rubber roller on the top and bottom of the sealing machine, and the pressure between them should be moderate. You only need to clamp the spring when adjusting the pressure.

2.The heat sealing speed is too fast

If the speed is too fast, the sealing part will be transported to the cold pressing part for cooling treatment before it has time to heat up, so that it can not meet the requirements of heat sealing quality, and the sealing of the packaging bag will not be secure.

3.The surface of the heat sealing knife of the sealing machine is uneven

The sealing machine's heat-sealing knife can be divided into upper and lower pieces. Usually, a thermocouple device is used to sense the temperature transmission. There are 3 screws on the heat sealing knife. The middle screw plays the role of support and reinforcement. The remaining 2 screws are equipped with pressure springs and gaskets to adjust the pressure of the heat sealing knife. The main reason for the unevenness of the surface of the heat sealing knife is that the screw in the middle of the equipment is inclined, not horizontal; there may also be uneven pressure on the pressure spring of the heat sealing knife.
