[0053] When in use, the plastic particles are poured into the first melting chamber 11, and the external motor and the heating source of the hot melt tube 15 are turned on. After the plastic particles enter the first melting chamber 11, they are heated by the hot melt tube 15, the rotating rod 14, the stirring rod 16, the driven disk 18 and the action disk 19 to achieve a hot melting effect. At the same time, the external motor drives the upper end of the rotating shaft 12 to rotate, thereby driving the rotating disk 13, the rotating rod 14, the stirring rod 16, the driven disk 18 and the action disk 19 to rotate in the first melting chamber 11.

When the toggle plate B41 is no longer in contact with the partition 23, the elastic force of the spring hinge D39 and the spring hinge C38 is used to restore the toggle plate A40 and the toggle plate B41 to their original state. The toggle effect of the toggle plate A40 and the toggle plate B41 is used to push and toggle the plastic particles, so that the plastic particles can be better processed by hot melt.

[0057] After one hot melt is completed, the plastic particles fall onto the guide plate 25. Through the diversion effect of the guide plate 25, the plastic particle melt flows on the partition bar 26 and is cut by the filter screen 27 until it falls onto the guide filter plate 28.
