Abstract
The invention discloses a plastic pipe extrusion molding apparatus, which mainly comprises a power mechanism, a hopper, a barrel, a barrel heater, a screw, a head, a sizer, a cooler, a drawer, a cutter and the like, a flow distribution plate is arranged at the joint between the barrel and the head, and a filter screen is arranged at the joint between the flow distribution plate and the barrel. The plastic pipe extrusion molding apparatus has the advantages that: the plastic pipe extrusion molding apparatus can filter impurities and unplasticized material in melted material flow and enhance the mixing and plasticizing effect, and the quality of produced pipes is high.
Description
Technical field:
The present invention relates to a kind of extrusion molding apparatus, particularly a kind of plastic pipe extrusion molding apparatus.
Background technology:
During plastic pipe extrusion molding of the prior art; Material is entered into after the barrel by the extruder hopper; Under the gyratory compaction and immixture of barrel temperature and screw rod; By powdery or the granular solid-state evenly continuous melt with certain flowability that is transformed into, plastic melt flows into head (being extrusion die) through flow distribution plate after moving near the barrel front end under the rotation extrusion effect of screw rod; And be shaped to the high temperature tube according to the shape of moulding parts in the head (mouthful mould, core etc.), be to produce desired plastic pipe under high temperature tubular plastic diameter-setting equipment, cooling device, draw-gear and the shearing device effect.The problem of its existence is: in the material unavoidably some impurity with fully plastifying material directly flow into head through flow distribution plate, cause the inner stress that produces of the tubing of being produced, the quality decline of the tubing of being produced influences the use of tubing.
Summary of the invention:
Be to solve the deficiency of prior art, the invention provides a kind of impurity with fully plastifying material can not pass through flow distribution plate and flow into head, the high plastic pipe extrusion molding apparatus of production pipe workpiece quality.
The technical problem that the present invention will solve realizes through following technical scheme; The plastic extruding forming device; Mainly comprise actuating unit, hopper, barrel, material tube heater, screw rod, head, diameter-setting equipment, cooling device, draw-gear and shearing device etc.; Described barrel and head junction are provided with flow distribution plate, it is characterized in that: the junction of described flow distribution plate and barrel is provided with screen pack.
Described screen pack is arranged on the flow distribution plate.
Described screen pack is the wire screen pack.
Described wire screen pack is the stainless steel wire screen pack.
In the prior art, the barrel of plastic pipe extrusion molding apparatus and head junction are provided with flow distribution plate, and its effect is to make streams become rectilinear motion by rotatablely moving; Flow into head, and be shaped to the high temperature tube according to the shape of shaping mould in the head, the present invention compared with prior art; Junction at flow distribution plate and barrel is provided with screen pack; Impurity in the filtering molten streams and plastifying material not, the resistance of increment materials flow, increment materials flow back pressure; Improve effect mixing or plasticizing, make goods more closely knit.
Further, described screen pack is arranged on the flow distribution plate, and flow distribution plate plays a supportive role to screen pack, prolongs the service life of screen pack.
Advantage of the present invention is: impurity in the filtering molten streams and plastifying material not, improve effect mixing or plasticizing, and the quality of the tubing of production is high, has improved production efficiency and economic benefit.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Label among the figure is: 1, actuating unit; 2, hopper; 3, barrel; 4, material tube heater; 5, screw rod; 6, flow distribution plate; 7, head; 8, screen pack.
The specific embodiment:
Below in conjunction with accompanying drawing and embodiment, the present invention is made further detailed description, but does not constitute any restriction of the present invention:
Like Fig. 1; The plastic extruding forming device; Mainly comprise actuating unit 1, hopper 2, barrel 3, material tube heater 4, screw rod 5, head 7, diameter-setting equipment, cooling device, draw-gear and shearing device etc.; Described barrel 3 is provided with flow distribution plate 6 with head 7 junctions, and described flow distribution plate 6 is provided with screen pack 8 with the junction of barrel 3; Described screen pack 8 is arranged on the flow distribution plate 6; Described screen pack 8 is the stainless steel wire screen pack.
Plastic extruding forming device of the present invention to different streams, is selected the screen pack of different meshes for use: when the big and poor stability of the viscosity of streams, select the big screen pack of order number for use; When the little and good stability of the viscosity of streams, select the little screen pack of order number for use.
As scheme embodiment just for the ease of understanding technical scheme of the present invention; Do not constitute restriction to protection domain of the present invention; Every interior any simple modification, equivalent variations and modification of perhaps according to technical spirit of the present invention above scheme being done that does not break away from technical scheme of the present invention all still belongs within the protection domain of the present invention.
