Problems solved by technology

The existing problem is that some unavoidable impurities in the material and insufficiently plasticized materials directly flow into the machine head through the splitter plate, causing stress inside the produced pipe, and the quality of the produced pipe decreases, which affects the use of the pipe.

Embodiment Construction

[0013] Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail, but does not constitute any restriction to the present invention:

[0014] Such as figure 1 , a plastic extrusion molding device, mainly including a power mechanism 1, a hopper 2, a barrel 3, a barrel heater 4, a screw 5, a head 7, a sizing device, a cooling device, a traction device, and a cutting device, etc., said A diverter plate 6 is provided at the joint between the barrel 3 and the head 7, and a filter 8 is provided at the junction between the diverter plate 6 and the barrel 3; the filter 8 is arranged on the diverter plate 6; The filter screen 8 is a stainless steel wire filter screen.

[0015] The plastic extrusion molding device of the present invention selects filter screens with different mesh numbers for different material flows: when the viscosity of the material flow is high and the stability is poor, a filter screen with a large mesh numb...

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: [0001] The invention relates to an extrusion molding device, in particular to a plastic pipe extrusion molding device. Background technique: [0002] When the plastic pipe in the prior art is extruded, after the material enters the barrel from the hopper of the extruder, under the action of the temperature of the barrel and the rotary compaction and mixing of the screw, it changes from a powdery or granular solid to a solid with a certain flow. After the plastic melt moves to the front end of the barrel, it flows into the machine head (that is, the extrusion die) through the splitter plate under the rotating extrusion of the screw, and forms parts (die) according to the shape of the machine head. , mandrel, etc.) are shaped into high-temperature tubular objects, and the high-temperature tubular plastic sizing device, cooling device, traction device, and cutting device are the plastic pipes required for production. The existing problems are: unavoidable impu...
