Machine is done to plastic extrusion billot pressure -vaccum

The utility model relates to a machine is done to plastic extrusion billot pressure -vaccum, including support and the bottom plate that sets up constitution " L " type perpendicularly, the support includes first montant and second montant, and the fixed first connector in first montant top sets up in the first connector and blots the head, and the fixed second connector in second montant top sets up in the second connector and weathers the head, the bottom plate top sets up the swirl air pump, blots the head and passes through the inlet scoop that the swirl air pump is connected to first corrugated tube, weathers the swirl air pump is connected to the head through the second corrugated tube the mouth of blowing. This pressure -vaccum is done machine setting and is blotted the head and weather the head and connect the swirl air pump, and the dewatering effect to the plastic extrusion billot when having simplified the structure is better, practices thrift manufacturing cost.
