Description

A kind of crush type plastic extrusion apparatus

Technical field

This utility model relates to plastic extrusion apparatus, is specifically related to a kind of crush type plastic extrusion apparatus.

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, its work process approximately as:

After extrusion system is heated to given technological temperature held for some time, starts motor, provided by reductor To the moment of torsion needed for screw rod and rotating speed.Plastics in hopper, under the effect of deadweight or feeder thrust, are entered spiral shell by charge door Groove.Along with the rotation of screw rod, plastics are fed forward under the effect of frictional force between screw rod.

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.In head of plastic extruder, mouth die is a profiled part, and material obtains one by it Determine the cross section of geometry and size, then through cooling and shaping and other operation, so that it may obtain the goods of forming.

In publication No. CN103568267A, date of publication be on February 12nd, 2014 patent of invention in disclose a kind of spiral shell Rod type plastics extruder, including barrel, installs screw rod in described barrel, arranges scraper on the upside of described screw rod, described scraper upper Side arranges discharge head, offers discharge opening one in described discharge head, and discharge opening two, described discharging are offered in the upside of described discharge opening one Discharge opening three is offered in the upside in hole two, forms cavity, wherein, described screw plastics between described discharge opening one and discharge opening two Extruder assembling transmission case oil pump, arranges heater outside described barrel.This plastic extruder can make product homogenization, But even results is poor, the most abundant；Chiller and tripper it is not provided with, it is easy to cause feed blocking at hopper Charging aperture, affects the normal work of plastic extruder；Being not provided with attemperator, the heat that heater produces is easy to dissipate Lose, also heating-up temperature cannot be controlled, be unfavorable for saving the energy.
