In order to achieve the purpose, the technical scheme of the utility model is to design a filtering screen plate structure in an extrusion machine head, which comprises an extrusion machine head main body and a filtering screen plate, wherein a through groove is arranged in the extrusion machine head main body, and the filtering screen plate is arranged in the through groove; the filter screen plate is provided with at least two connecting rods perpendicular to the plane of the filter screen plate, one end of each connecting rod is connected with the filter screen plate, the other end of each connecting rod is positioned at the feed end of the through groove, the other end of each connecting rod is also provided with a connecting piece, the connecting pieces are perpendicular to the connecting rods, and a support gas rod is arranged between each connecting piece and the feed end of the through groove; the inner wall of the through groove is provided with a groove matched with the connecting rod, and the connecting rod reciprocates along the groove; the filter screen plate is provided with heating wires along the edge of the screen plate, the end part of at least one connecting rod at the feeding end is provided with a heating wire switch, and a connecting wire is arranged between the heating wires and the heating wire switch.
The support gas rod can be fixedly connected with the connecting piece on the connecting rod and also can be fixedly connected with the feeding end of the through groove.
A feeding accumulation area is formed between the filter screen plate and the feeding end, the thickness of the feeding accumulation area is reduced so as to conveniently reduce the consumption of raw materials, and the replacement of the filter screen plate is convenient.
As the preferred technical scheme, the circumferential edge of the filter screen plate is provided with a groove, the heating wire is positioned in the groove, and the copper sealing ring is arranged outside the groove. When the screen plate is replaced by the plastic extruding machine, the material is solidified on the screen plate and the inner wall of the through groove, so that the replacement difficulty is high, a heating device is arranged at the edge of the screen plate, the raw materials of the inner wall and the screen plate are melted, and the screen plate is convenient to replace.
As an optimal technical scheme, the edge thickness of the filter screen plate is 1.5-2 cm, and the thickness of the screen plate is 6 mm.
As the preferred technical scheme, the feed end of logical groove is equipped with the locating part of dismantlement formula. When the locating part prevents to clear up and filters the otter board, filter the otter board and lead to the groove separation, when the clearance filters the otter board, the otter board is located logical inslot portion, the accurate location installation after the clearance of being convenient for is ended.
As a preferable technical scheme, the end of the traction rod, which is positioned at the feeding end, is provided with a heat insulation handle. When the filter screen plate is cleaned, the edge of the screen plate is heated firstly, so that materials solidified on the screen plate and the inner wall are melted, cleaning is facilitated, the traction rod is prevented from being overheated, and therefore a handle is arranged at the end of the traction rod.
As a preferred technical scheme, the connecting rod and the inner part of the through groove are positioned on the same curved surface or plane.
The utility model has the advantages and the beneficial effects that: by increasing the thickness of the filter screen plate, the distance of the head material accumulation area of the extruder is reduced, and the head material loss of the extruder is reduced. The filter screen plate structure is convenient to replace by adding a heating device at the edge of the screen plate.
