[0002] A hot melt machine is a device that uses electric heating to melt plastic hot melt parts to workpieces. It is mainly used for riveting and embedding disc-shaped plastic parts of different heights.

[0003] At present, each production line is equipped with a different model of hot melt machine, that is to say, one model of hot melt machine can only achieve welding between certain specific workpieces. If the structure of the workpiece is optimized and changed, the original model of hot melt machine can no longer be used in this production line and needs to be replaced. After the replacement, the parameters need to be adjusted, which takes a lot of time and is troublesome.
