Abstract
The utility model discloses a plastic pipe extruder. The utility model comprises a machine barrel, a machine head, a cooling water jacket, a pressure regulating air plug, and a heating device. A main hopper and a subsidiary hopper are arranged in parallel above the feed inlet on one end of the machine barrel, and between the connecting press plates on the back end of the machine barrel, at least two filter screens are provided, one of which is arranged in the machine barrel and the other is arranged on the outboard of the machine barrel and is contacted with a screen-changing screw. Between the couplings in front end of the cooling water jacket, a fluoroplastic insulation ring is provided. A feeding screw is arranged in the hopper, and the front end of the screw is provided with a blade wheel, which can directly mix the material and make the raw material be stirred homogeneously. Replacing the filter screen without closing down alters the disadvantages in the past that replacing the screen takes time, takes power, and lead out waste materials. The installation of the new material fluoroplastic insulation ring has a good heat-insulation effect, and greatly slows up the heat transmission between the machine head and the cooling water jacket, making the extrusive commodities have smooth surfaces. The inner chamber of the plastic pipe which is refrigerated is provided with the pressure regulating air plug and a screwconical nut, which makes the press plate move outward and act the support function for the rubber pad, avoiding influence of the product quality caused by that the rubber pad is grinded and the air plug escapes air.

The utility model content
The purpose of this utility model is to provide a kind of can directly and expect that not parking machine is replaceable screen pack, the plastic tube extruder of good product quality.
The technical solution of the utility model is: the utility model plastic tube extruder, comprise machine barrel, head, cold water jacket, pressure regulation vent plug and heater, the machine barrel outer wall is provided with heater, being connected pressing plate by two between machine barrel and the head connects, the plastic insulation circle is set between two terminal pads, be connected by two terminal pads between head and the cold water jacket, regulating vent plug is connected with head by screw rod, main Luo Gang is set in the machine barrel, be connected with reducer output shaft, it is characterized in that: the charging aperture top of machine barrel one end is set up in parallel main hopper and secondary hopper, and feed hopper bottom is provided with a feeding Luo Gang, feeding spiral shell thick stick front end is provided with impeller, and the rear end is provided with drive sprocket; Be set up in parallel at least two screen packs between two connection pressing plates, a screen pack is arranged in the machine barrel, and another is arranged on the machine barrel outside, and the screen pack of machine barrel arranged outside contacts with a draping screw rod.
The described insulated ring that is provided with between two terminal pads is the fluoro-containing plastic insulated ring.
Described pressure regulation vent plug is made up of vent plug base plate, rubber cushion and movable pressing board, rubber cushion and movable pressing board are by being bolted on the vent plug base plate, screw rod is set in the middle of the vent plug base plate, one side of the endoporus that cooperates with screw rod forms a taper chamber, this chamber is corresponding with the tapered cup nut that is arranged on spiro rod rear end, movable pressing board is that four fanning strips combine, and has elongated slot on the fanning strip.
The advantage of this extruder:
1, feeding Luo Gang is set in hopper, spiral shell thick stick front end is provided with impeller, can directly and expect, raw material is stirred, and saves the labour, save electricity;
2, do not shut down the replacing screen pack, changed waste time and energy the shortcoming of waste material of draping in the past;
3, the installation of new material fluoro-containing plastic insulated ring, good heat-insulation effect has been slowed down the heat transmission between head and the cold water jacket greatly, makes the product surface of extruding smooth;
4, at the plastic tube inner chamber that is cooled the pressure regulation vent plug is set, the precession tapered cup nut outwards moves movable pressing board, and rubber cushion is played a supportive role, and avoiding influences product quality because of the gas leakage of rubber cushion wearing and tearing vent plug.
