The auxiliary material feeding machine barrel is used for feeding the materials into the extruder, so that the yield of the extruder can be increased; and furthermore, the cooling effect is good, and the quality of a product can be guaranteed.
Description
Technical field
The present invention relates to a kind of production equipment of plastic conduit, specifically be used for the auxiliary reinforced machine barrel of single screw extrusion machine.Background technology
In the plastic conduit manufacturing, the increase of the heavy caliber pipe quantity of As market, the output of its main production equipments extruder also needs to improve.And at present effective method is, increases the output of extruder through the rotating speed that improves extruder.But when improving the extruder rotating speed, because the raising of screw speed, the temperature of screw rod and charging machine tube inner wall constantly raises, and plastic raw materials can plastify under the situation of being heated in advance, thereby has directly influenced reinforced carrying out smoothly.In the prior art, be one section helicla flute of turning on the external diameter of machine barrel for the cooling of charging machine barrel, in groove around on copper tube; Connect cooling water, the charging machine barrel is cooled off indirectly, this cooling means effect is relatively poor; And can influence plastic pellet entering charge door, thus production output reduced, because reinforced instability; Make the pressure in the machine barrel produce fluctuation, thereby influence product quality.
Summary of the invention
The problem that the present invention will solve provides a kind of single screw extrusion machine with auxiliary reinforced machine barrel, adopts this machine barrel reinforced to extruder, can increase the output of extruder, and good cooling results, can guarantee product quality.
For addressing the above problem, take following scheme:
Single screw extrusion machine of the present invention comprises outer adapter sleeve with auxiliary reinforced machine barrel, and outer coupling sleeve one end is connected with reduction box, and the other end is connected with extruder.Have charging machine barrel and the two to be fixed connection in the said outer adapter sleeve, outer adapter sleeve all has opening on the position identical with charging machine barrel sidewall, is connected with charging aperture on the opening.In the said charging machine barrel screw rod is arranged, an end of the corresponding reduction box of screw rod cooperates through being sealed rotational between sealing ring and charging machine barrel.Be characterized on the inwall of said charging machine barrel some axial straight troughs being arranged.
Further improvement project of the present invention be said charging machine barrel charging aperture to and the extruder link between outer wall on the outer groove of annular is arranged, the bottom land of annular outer groove has the helicla flute that axially is connected along the charging machine barrel.Be with sealing shroud on the outer groove of said annular, sealing shroud equates that with the axial length of the outer groove of annular the thickness of sealing shroud equates with the outer depth of groove of annular.On corresponding position, charging machine barrel helicla flute two ends, perforate is arranged on said sealing shroud and the outer adapter sleeve, be connected with water inlet pipe in the perforate near charging aperture one end, be connected with outlet pipe in the perforate of the other end.Wherein, the bottom land of the outer groove of said annular all is with sealing ring in the outside at helicla flute two ends.
Take such scheme, have the following advantages:
Owing on the charging machine tube inner wall of single screw extrusion machine of the present invention with auxiliary reinforced machine barrel some axial straight troughs are arranged; This has just increased the amount that plastic raw materials gets into machine barrel; Mix and plasticizing zone thereby brought into by screw rod better, the whole charging process is comparatively stable, thereby makes the interior pressure in the machine barrel keep stable; When having increased output, guaranteed product quality.
In addition; On the charger drum outer wall, process helicla flute; Make cooling water directly cool off the charging machine barrel, guarantee the temperature-resistant of charging aperture, and guarantee plastic raw materials in the temperature in the district of mixing within the technological requirement scope; In order to avoid plastic raw materials plastifies in advance and influences inlet amount, this cooling means effect is better.
Description of drawings
Fig. 1 is the structural representation of single screw extrusion machine of the present invention with auxiliary reinforced machine barrel;
Fig. 2 is the A-A cross-sectional schematic of Fig. 1.
The specific embodiment
As shown in Figure 1, single screw extrusion machine of the present invention comprises outer adapter sleeve 2 with auxiliary reinforced machine barrel, and outer coupling sleeve 2 one ends are connected with reduction box 1, and the other end is connected with extruder 12.Have charging machine barrel 4 and the two to be fixed connection in the said outer adapter sleeve 2, outer adapter sleeve 2 all has opening on the position identical with charging machine barrel 4 sidewalls, is connected with a charging aperture 5 on the opening jointly.In the said charging machine barrel 4 screw rod 6 is arranged, do not have screw thread on the end of screw rod 6 corresponding reduction boxes 1, it is sealed rotational through 4 of sealing ring 3 and charging machine barrels and cooperates.Some axial straight troughs 13 are arranged on the inwall of said charging machine barrel 4.Said charging machine barrel 4 charging aperture 5 to and extruder 12 links between outer wall on the outer groove of annular is arranged, the bottom land of annular outer groove has the helicla flute 9 that axially is connected along the charging machine barrel.Be with sealing shroud 7 on the outer groove of said annular, sealing shroud 7 equates that with the axial length of the outer groove of annular the thickness of sealing shroud 7 equates with the outer depth of groove of annular.On corresponding position, charging machine barrel helicla flute 9 two ends, perforate is arranged on said sealing shroud 7 and the outer adapter sleeve 2, be connected with water inlet pipe 8 in the perforate near charging aperture 5 one ends, be connected with outlet pipe 11 in the perforate of the other end.
Wherein, the bottom land of the outer groove of said annular all is with sealing ring 10 in the outside at helicla flute 9 two ends, thereby the spiral fluted cooling water does not leak outside on the charging machine barrel that can guarantee to flow through.
During operation, drive screw rod 6 rotations of single screw extrusion machine of the present invention with auxiliary reinforced machine barrel by reduction box 1, plastic raw materials gets in the charging machine barrel 4 from charging aperture 5 simultaneously, and promotes to get into extruder 12 by the screw thread on the screw rod 6.In plastic raw materials entering process, cooling water to be introduced from water inlet pipe 8, cooling water flow can directly cool off it when charging machine barrel helicla flute 9, and is flowed out by outlet pipe 11 at last.
