Description

A kind of plastic extruder extruder head device

Technical field

This utility model relates to plastic extruder extruder head, is specifically related to a kind of plastic extruder extruder head device.

Background technology

Along with the extensive application of plastic extruder moulding process, the type of plastic extruder is increasing, and sorting technique is also It is not quite similar.Horizontal and vertical extruder can be divided into by the locus of screw rod；Common extrusion can be divided into again by the rotating speed of screw rod Machine, high speed and hypervelocity extruder；Divide by the quantity of screw rod, be divided into elastirotor extruder, single screw extrusion machine, twin-screw extrusion Machine and multi-screw extruder etc., among these, the application of single screw extrusion machine is relatively broad.

In forming process, material adds to plastic extruder from hopper with powdery or graininess, will complete conveying, pressure The processes such as reality, compression, fusion plastification, the uniform melt body of chemical conversion.At screw rod feeding section, loose solid grain (or material end) is full of spiral shell Groove, along with the continuous conveying of material, material starts to be compacted.

After material enters compression section, owing to the screw channel degree of depth gradually becomes shallower as and the resistance of head, make plastics gradually Form high pressure, and be compacted further.Meanwhile, at barrel external heating device and screw rod with barrel inner surface to material Strong agitation, mix and under the effect of the produced internal friction shear heat such as shearing, plastics temperature constantly raises, with barrel phase The certain point of contact, plastics temperature arrives fusing point, starts to melt.Along with the conveying of material, continue heating, melted inventory by Cumulative many, and non-fused mass doses reduces accordingly.About at the end of compression section, whole materials are all changed into viscous state, but At this moment each point temperature is not yet uniform, more uniform through the homogenization just ratio of homogenizing zone.Finally, fused mass is anticipated by screw rod It is squeezed into head amount, level pressure, constant temperature.The effect of head is that the plastic melt of rotary motion is changed into parallel lines motion, Uniform and stable plastic melt is imported in die sleeve, and give plastics with necessary briquetting pressure.

In publication No. CN102490343A, date of declaration be on June 13rd, 2012 patent of invention in disclose one and mould Material cross-head, including outer cylinder body assembly and be installed on the element kit in described outer cylinder body assembly, described outer cylinder body group Part includes that outer cylinder body, described element kit include that chimney filter, the discharging opening of described chimney filter connect with the discharging opening of described outer cylinder body, institute State and be pasted with drainage screen on the periphery tube wall of chimney filter.This head of plastic extruder can be first with filter screen to entering outer cylinder body group The high temperature plastifying material of part filters bigger impurity, and recycling chimney filter carries out secondary filter.But this head of plastic extruder two Secondary filter effect is poor, and static chimney filter cannot improve filter effect, and also limits the flow of high temperature plastifying material, reduces Work efficiency；Additionally, high temperature plastifying material is easy to be blocked at chimney filter and filter screen because internal temperature reduces, cause plastics Extruder quits work, and reparation is wasted time and energy.
