When the granule packaging machine is used for a long time, the sealing temperature will become out of control. This fault is manifested as a malfunction of the temperature gauge, inability to control the temperature, unstable heat sealing temperature, and the sealing part is either burnt or not tightly sealed, resulting in deformed and unsightly sealing. The following are the reasons for the uncontrolled sealing temperature of the granule packaging machine.

1. One reason is that the heat sealing quality of the composite material itself is poor, and the heat sealing coefficient changes, resulting in different temperatures being accepted.

2. The mechanical reason is that the heat sealing pressure is uneven. Simply adjust the pressure tension spring of the heat sealing knife to ensure that the pressure is uniform. At the same time, the pressure contact surface of the heat sealing knife should be kept clean and free of dirt.

3. The primary cause of this malfunction is that the thermometer is broken and must be repaired; In addition, the thermocouple may also be broken and unable to transmit the induced temperature to the thermometer normally. Just replace it with a thermocouple of the same type and standard.
