Description
Technical field
The utility model relates to a kind of macromolecular material plastic pipe processing equipment, specifically, relates to the plastic pipe coating head that a kind of outer wall to plastic pipe applies modified layer.
Background technology
For raising plastic pipe performance, give its new function, often need modify processing to the plastic tube outer surface, such as intensity, toughness, the elastic modelling quantity of certain material coating of coating with the raising plastic pipe, or hinder oxygen, static electricity resistance, anti-flammability etc.
The existing coating unit of extruding is to plastic pipe coated polymer modified layer the time, polymer melt is that the axis direction that is parallel to tubing flows, owing under the elongational flow state, extrude coating, the macromolecular chain of polymer can axially form certain orientation along tubing, makes the tubing axial strength be higher than circumferential strength.Stressing conditions analysis according to the pressure-bearing plastic pipe, the pressure-bearing plastic tube is in running, the stress that produces along circumference in the tube wall is about and is parallel to more than 2 times of stress that the tubular axis line produces in the tube wall, so to common pressure-bearing plastic pipe, the circumferential of stress maximum just in time is the most weak direction of tubing intensity.This intensity anisotropy is very unreasonable for the tubing of discharge pressure fluid.
For this reason, Chinese patent literature CN101332667A discloses a kind of long glass fiber-reinforced plastics pipe extruder head, be specifically related to a kind of plastics circular pipe extruder head that has the composite characteristics of the online spiral of long glass fibres on the plastic extruder that is installed in, this device has the input of glass fibre and mixed distribution device and the plug tumbler of fiber and melt, the mixed distribution device of this head is realized certain-length is input in the plastic melt of plastic through the glass fibre of coupling agent treatment, and make glass fibre be mixed in the plastic melt equably, become fibre and mould mixed melt, the plug tumbler of this head is realized by the rotation of plug melt being flowed from moving to become around the plug hand of spiral along the mandrel axis linear flow at plug and mouthful intermode, up to curing.Polymer molecule and long glass fibres have improved the circumferential strength of tubing greatly along the hand of spiral orientation of axis in the plastic pipe that said apparatus is extruded.
But, circumferentially to arrange be to realize by the rotation of plug in the mouth mould to long glass fibres in the above-mentioned plastic pipe, need add and drive power and corresponding transmission device (as plug rotational speed regulation sprocket wheel, plug rotating drivetrain wheel support, plug rotating drivetrain bar, rotatable plug and driven transmission sprocket wheel), not only consumed energy and handpiece structure complexity are set; In addition, drawback that can't overcome of said apparatus is, melt is rotating with plug and is being released the typing that is cooled of a mouthful mould gradually, the rotation stress that Guan Pizhong exists will remain to always tubing by severing before, therefore tubing is except carrying out the rectilinear motion, increased a kind of unnecessary rotatablely moving again, this is that the extrusion molding institute of all thermoplastic plastic pipes is unallowed; In addition, the processing melt temperature of extruding of most plastics is about about 200 ℃, have up to 400 ℃ about, melt pressure is up to counting MPa to tens of MPas in extrusion for plastics, and the polymer melt pressure of having dosed glass is inevitable higher, causes the sealing between plug and the bearing block very difficult, cause melt leakage easily, the equipment that influences runs well, and increases operator's labour intensity, can cause device damage etc. sometimes.
