The hot melt adhesive cools before bonding. The reasons and solutions are as follows:
(1) The use temperature of hot melt adhesive is low → increase the use temperature;
(2) The opening distance is too long → reduce the opening distance;
(3) The conveyor belt speed is too slow → increase the conveyor belt speed;
(4) The amount of glue applied is not enough → increase the amount of glue applied;
(5) The temperature of the adhered material and the environment is low → increase the temperature of the environment or the adhered material;
(6) The pressure is inappropriate → adjust the pressure.
It needs to be analyzed one by one for different reasons to obtain corresponding solutions.
