[0035] Working Principle: The single-shaft ring-type glue mixer mainly consists of a drive motor 17, a mixer housing, a stirring mechanism, a glue spraying device 19, a cooling circulation system, a screw lifting device 20, and an electrical control system. The drive motor 17 drives the pulley 14 to rotate, which in turn drives the belt 16 to rotate. The belt 16 then drives another pulley 14 to rotate, which in turn drives the main shaft 1 to rotate. The rotation of the main shaft 1 and the stirring paddle 9 creates a spiral propulsion motion. At this time, wood shavings and glue enter the mixer through the feed inlet 7 and the glue spray nozzle 191, respectively. Under the action of high-speed rotation, the stirring paddle 9 drives the wood shavings and glue to form a high-speed moving wood shaving ring on the inner wall of the machine housing. Under the action of rotational thrust and friction, the wood shavings and glue are propelled from one end to the other, that is, the wood shavings rotate. Due to the continuous action of the stirring claws 6, the relative speed between the wood shavings changes, thereby generating mutual friction and achieving the purpose of uniform distribution of glue.
