The entrance pressing wheel 31 is fixed in position, and the entrance I-wheel 23 can adjust the gap with the entrance pressing wheel 31 through the entrance slot 21. The position of the entrance I-wheel 23 is adjusted according to the thickness of the plastic, so that the gap between the entrance I-wheel 23 and the entrance pressing wheel 31 just presses the plastic belt.
