Abstract
The utility model relates to the field of PVC manufacturing equipment, in particular to a perforated plate for PVC (polyvinyl chloride) extrusion. The perforated plate comprises a body, a plurality of through holes are arranged on the body, the runner of each through hole has obliqueness. The through holes are respectively positioned on an inner ring and an outer ring which are concentric, and the runners of the through holes on the inner ring and the outer ring are mutually distributed crosswise. After the perforated plate is adopted, the original molten materials are overturned through crossing and inclination of special inner holes and outer holes to change the flowing direction of the molten materials, further black and yellow lines and impurities on the surface of white extruded products can be removed, turbulent flow, which comes out by rotating a conical double screw, of the material can be evenly extruded out of a mold after being homogenized by the runner of the perforated plate, and production stability can be better ensured.
Description
Technical field
The present invention relates to PVC manufacturing equipment field, be specially a kind of PVC and extrude and use porous plate.
Background technology
Usually the little foaming of PVC when extrusion without porous plate, but along with extruder increases service life, the variation of screw clearance, black, yellow line and some impurity have appearred at the PVC product surface of extruding, this all is that export inspection can't be passed through, the direct extrusion die of sinuous flow that the while material is gone out by the rotation of cone twin-screw can not guarantee the stability of producing; Above-mentioned drawback causes the product runner complicated, processing difficulties, and the polishing trouble easily is stained with precipitate.
Summary of the invention
For the defective that prior art exists, purpose of the present invention provides a kind of PVC that can eliminate the impurity of product surface and improve production stability to extrude and uses porous plate.
Its technical scheme is: comprise body, and uniform a plurality of through holes on it, the runner of described through hole all has gradient.
Such scheme can also further be improved to:
Described through hole lays respectively at concentric inside and outside two circles, and the mutual arranged crosswise of the runner of inside and outside ring through hole.
The runner gradient of described through hole is greater than 10 degree and less than 37 degree, and preferred gradient is greater than 15 degree.
The aperture of described through hole is greater than 4 millimeters and less than 7 millimeters, and described number of openings is greater than 12 and less than 30.
Described body is cylinder, its diameter is the 25-75 millimeter, be preferably 30 millimeters, 40 millimeters, 50 millimeters, 60 millimeters or 70 millimeters, its thickness is the 37.5-57.5 millimeter, is preferably 40 ± 2.5 millimeters, 45 ± 2.5 millimeters, 50 ± 2.5 millimeters or 55 ± 2.5 millimeters.
The utility model is easy to operate, with low cost, and designed porous plate has been eliminated black, yellow line and the partial impurities of PVC product surface in process on probation, and effective 1 ~ 3 year service life of extension device.This product is through long-time on probation, the PVC product surface and on probation with ing before ratio, stablize from fineness, the fine and smooth degree of section with the angle of angle section bar and all to have greatly improved, the production cycle has also extended to present 10 ~ 15 days by original 5 ~ 7 days.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the arranged crosswise schematic diagram of Internal and external cycle through hole among Fig. 1;
Among the figure, 1, body, 2, interior ring through hole, 3, outer ring through hole.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
With reference to Fig. 1, a kind of PVC extrudes and uses porous plate, body 1 is cylinder, uniform interior ring through hole 2 and outer ring through hole 3 with same slope and mutual arranged crosswise on it, namely from a side of body: the runner of interior ring through hole 2 is outward-dipping (dispersing) all, the flow direction of outer ring through hole 3 all slopes inwardly (polymerization), and following parameter is Combination Design according to actual needs:
1, interior ring through hole 2 and outer ring through hole 3: total number of openings is greater than 12 and less than 30, and the aperture is greater than 4 millimeters and less than 7 millimeters, and the runner gradient of through hole (being the angle of runner axis and vertical line) is greater than 10 degree and less than 37 degree, and preferred gradient is greater than 15 degree., be preferably greater than 15 degree.
2, body 1:,: diameter can be selected between the 25-75 millimeter, be preferably 30 millimeters, 40 millimeters, 50 millimeters, 60 millimeters or 70 millimeters, its thickness can be selected between the 37.5-57.5 millimeter, is preferably 40 ± 2.5 millimeters, 45 ± 2.5 millimeters, 50 ± 2.5 millimeters or 55 ± 2.5 millimeters.
After adopting porous plate, original molten material is intersected to tilt by exclusive inner/outer hole, upset and changed the fused materials traffic direction, and then reached black, yellow line and the impurity of eliminating white extruded product surface, and the sinuous flow that material is gone out by the rotation of cone twin-screw, through uniform extrusion die after the porous plate runner homogenizing, so, the stability of producing can better be guaranteed.
