The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
Special had of the present invention refers to that extruder screw tail end is to the part between machine mouth, extruder special had is the key member of thermoplastic material strip moulding, make the melt of extruder change single streamlined flow state into by spiral rotating flow regime by head, by the temperature control of heating system, plastic melt is further plastified simultaneously, make it produce needed material strip briquetting pressure by the adjustment of compression ratio again, increase the compactness of plastic extrusion material strip, intensity and the toughness of material strip are improved, per os mould obtains the continuous material strip of required square-section, be wound in plastic cylindrical tank body by required diameter requirement again.
Specifically, thermoplastic is extruded material strip special had and is comprised connector 1, nozzle 4, head, connector has connecting hole 1-1, connector one end (A face in Fig. 2) is connected with extruder, the other end connects nozzle 4, in nozzle, there is spray orifice 4-1, spray orifice 4-1 runs through whole nozzle, insert in the connecting hole of connector one end of nozzle, the other end is connected with head, preferably spray orifice cross sectional shape is roughly funnelform structure, there is large end and small end, large end is coniform shower nozzle 4-2, small end is spray tail 4-3, spray tail is communicated with discharge opening 14, the nozzle end of nozzle inserts in the connecting hole 1-1 of connector, distributor 2 is arranged on the nozzle of this end of shower nozzle, distributor 2 covers shower nozzle, on head, there is discharge opening 14, spray orifice 4-1 is communicated with discharge opening 14, head can be integral structure, also can be split-type structural, the preferred head of the present invention is split-type structural, comprise head upper body 10, head lower body 12, head upper body is connected by bolt 5 with head lower body, and all there is blow tank on head upper body and head lower body, and blow tank symmetrical configuration, after head upper body is connected with head lower body, two blow tanks fasten, form a complete discharge opening, the structure of discharge opening is rectangle, certainly the structure of discharge opening can be also other shapes, the structure choice that the selection of discharge opening need to be shaped according to plastics material strip.Adjuster 9 is arranged on head upper body, head upper body is also provided with and adjusts bolt 8 simultaneously, adjusting bolt is connected with adjuster, adjuster and discharge opening next-door neighbour arrange, adjuster can pass discharge opening, in front end and/or rear end (front end or the rear end of part between connector and head) of nozzle, humidity control system 3 is installed, near spray-nozzle type sprinkler head end, temperature measuring equipment 13 is being installed, temperature measuring equipment is arranged between humidity control system and shower nozzle.
