Working principle of hot melt adhesive coating machine

Working principle of hot melt adhesive coating machine  

Hot melt adhesive coating machine entered the Chinese market in the mid-eighties, and Chinese machinery manufacturers made this equipment in the nineties.  At first, Hot melt adhesive coating machine is only used in small industries such as cosmetics, and then sanitary cotton, packaging industry slowly began to use hot melt adhesive, so in mainland China and Eastern European countries, the Middle East countries began to use hot melt adhesive machine this industrial equipment.  Industrial use of hot melt adhesive can be heated after melting, coating and cooling after the rapid solidification of the characteristics of the implementation of bonding of the base material. So the most basic function of the hot melt adhesive coating machine should be to melt the hot melt adhesive and coating on the base material.  

In this way, we can define the hot melt adhesive coating machine as: it is a kind of solid hot melt adhesive melting, and through the pressure device will melt into liquid adhesive transported to the coating device for the substrate coating, set temperature heating control, pressure function, liquid adhesive transport and extrusion coating function in one of the mechanical and electrical equipment.  The functions of the above parts complement each other, which link failure can not carry out normal spraying and coating work. 

Its working process is as follows: add hot melt adhesive in the melt tank - heating the adhesive melter ( hot melt tank) - heating hose and coating device - start the pressure device to transfer glue - start the coating device according to the process requirements.
