Abstract
The utility model discloses a production line device special for a PP (polypropylene) honeycomb board for a vehicle. The production line device comprises a dual-screw rod extruder and a sheet die; a cylinder of the dual-screw rod extruder is connected with a vacuum pump by an exhaust pipe; a die cavity of the sheet die adopts a hanger type structure; a material inlet of the sheet die is connected with an extruding port of the dual-screw rod extruder by a melt pump. On one hand, a part, corresponding to a plasticizing and homogenizing part, on the cylinder is communicated with an air suction port of the vacuum pump, so gas, small melt molecules and moisture, which are generated in the machining process of the dual-screw rod extruder, are sucked away from the cylinder by the vacuum pump, the pressure in the cylinder of the dual-screw rod extruder is controlled to be negative pressure of 0.08-0.1Mpa and the mixing and plasticizing effects of the PP material are well improved; on the other hand, the melt pump is arranged between the extruding port of the dual-screw rod extruder and the material inlet of the sheet die, so the unstable discharging phenomenon of the dual-screw rod extruder is avoided, uniform gram weight of extruded sheets of the sheet die is ensured and the product quality is improved.
Description
Technical field
The utility model relates to the technical field of PP honeycomb board production line device, and a kind of automobile-used PP cellular board special production line device is specifically provided.
Background technology
The process units of existing production polyolefine material based sheet is the sheet die that adopts double screw extruder and be connected to extrusion place mostly, but because double screw extruder is in extrusion, have the unsettled phenomenon of discharging, thereby can make the grammes per square metre of the sheet material that sheet die extrudes inhomogeneous, affect product yield.
In addition, double screw extruder, in extrusion, due to the existence of the little molecule of melt and moisture, makes to have aqueous vapor in the machine barrel of double screw extruder, thereby be unfavorable for that polyolefine material carries out mixing and plasticizing, and then also can have influence on the quality of the sheet material that sheet die extrudes.
Summary of the invention
In order to overcome above-mentioned defect, the utility model provides a kind of automobile-used PP cellular board special production line device, and this device not only can well be removed the aqueous vapor in double screw extruder machine barrel, is beneficial to the mixing and plasticizing of PP material; And can also effectively avoid the unsettled phenomenon of double screw extruder discharging, guarantee to make the grammes per square metre of sheet die extrusion sheet even.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of automobile-used PP cellular board special production line device, comprise double screw extruder and sheet die, the machine barrel of described double screw extruder is connected with vavuum pump by blast pipe, the die cavity of described sheet die adopts rack-style structure, and the feeding mouth of described sheet die is connected in the extrusion of described double screw extruder by Melt Pump.
As further improvement of the utility model, in the machine barrel of described double screw extruder, location is provided with two screw rods, and the spiral shell rib on every screw rod is divided into feed zone, compression section and plasticizing homogenizing zone; Another also on described machine barrel and the position locating open of corresponding described plasticizing homogenizing zone be provided with exhaust outlet, described exhaust outlet is communicated in the air entry of described vavuum pump by blast pipe.
As further improvement of the utility model, on the extrusion of described double screw extruder, also location and installation has a net-changing device, and described net-changing device is connected in the charging aperture of described Melt Pump.
As further improvement of the utility model, the order number of described net-changing device upper filter screen net sheet is 80～125 orders.
The beneficial effects of the utility model are: on the one hand, by on machine barrel and the position locating open of corresponding plasticizing homogenizing zone be provided with exhaust outlet, and exhaust outlet is communicated in the air entry of vavuum pump by blast pipe, double screw extruder produces in process like this little molecule of gas, melt and moisture just can be taken away through vavuum pump from this exhaust outlet, thereby the pressure that can control in double screw extruder machine barrel is negative pressure 0.08～0.1MPa, well improved the mixing and plasticizing effect of PP material; On the other hand, by being provided with a Melt Pump between the extrusion at double screw extruder and the feeding mouth of sheet die, can effectively avoid the unsettled phenomenon of double screw extruder discharging, guarantee to make the grammes per square metre of sheet die extrusion sheet even, improve the product quality of automobile-used PP cellular board.
