According to the extruding system of the extruding machine, the diameter of the screw and the diameter of the screw tube are increased, the R angle of the thread angle arranged on the screw is increased, and accordingly the grinding efficiency of the screw is improved and accordingly the extruding system is suitable for machining of powder mixed coating and the extrusion work of materials with 30% of powder mixed amount can be achieved.
Description
Technical field
The invention belongs to extruder technology field, be specifically related to a kind of extrusion system of extruder.
Background technology
extruderbe made up of extrusion system, transmission system and heating and cooling system.
Extrusion system comprises screw rod, barrel, hopper, head and mould, and plastics plastify uniformly melt by extrusion system, and in this course under institute's build-up pressure, by screw rod continuous print extruder head.Being described as follows of each parts of extrusion system:
screw rod: the main parts being extruder, it is directly connected to range of application and the productivity ratio of extruder, is made up of the steel alloy of high-strength corrosion-resisting.
Barrel: be a metallic cylinder, generally with heat-resisting, compressive resistance is higher, the composite steel tube of firm wear-resisting, corrosion resistant steel alloy or interliner alloy steel is made.Barrel coordinates with screw rod, realizes the pulverizing to plastics, softening, melting, plasticizing, exhaust and compacting, and to formation system continuous uniform conveying sizing material.The length of general machine barrel is 15 ~ 30 times of its diameter, obtains fully heating to make plastics and fully plastifies as principle.
Hopper: feed hopper bottom is equipped with cutting device, so that adjustment and cut-out stream, window and marking meter are equipped with in the side of hopper.
Head and mould: head is made up of steel alloy inner sleeve and carbon steel overcoat, and head is built with mould.The effect of head the plastic melt of rotary motion is changed into parallel lines motion, in the importing die sleeve of uniform and stable, and gives plastics with the briquetting pressure of necessity.
The effect of transmission system is drive screw, and the moment that supply screw rod is required in extrusion and rotating speed, be made up of motor, decelerator and bearing etc. usually.
Heating is the necessary condition that plastic extrusion process can be carried out with cooling.Heater, by the plastics in external heat cylinder, makes it to heat up, to reach the temperature required for technological operation.Cooling device is arranged in order to the temperature range ensureing plastics and be in technological requirement.The waste heat that the shearing friction rotated to get rid of screw rod specifically produces, to avoid, temperature is too high makes plastics, incipient scorch or sizing difficulty.
At present, due to the screw rod in the extrusion system of extruder and barrel diameter too little, the radius at the R angle of the thread bush that screw rod is arranged is also little, and screw thread is not given prominence to, and therefore, is only applicable to the coating producing sub-light powder and high light powder, but not being suitable for processing mixes the coating of powder.The grinding efficiency of the screw rod of the extrusion system of extruder is low, can not complete well mix powder material extrude work.
Summary of the invention
The invention provides a kind of extrusion system of extruder, be applicable to process the coating mixing powder, the grinding efficiency of the screw rod of the extrusion system of extruder is high, can complete well mix powder material extrude work.
Concrete technical solution of the present invention is: a kind of extrusion system of extruder, comprise screw rod, barrel, hopper, head and mould, the enlarged diameter of described screw rod, internal diameter is constant, the diameter of described barrel is corresponding is increased to the equal diameters with described screw rod, the radius at the R angle of the thread bush that described screw rod is arranged is increased to 10mm by 6mm, and lead is constant.
Further, the diameter range of described screw rod is increased to 63 ± 0.3mm by 58 ± 0.3mm, and the diameter of described barrel is corresponding is increased to the equal diameters with described screw rod, and namely the diameter range of described barrel is also increased to 63 ± 0.3mm.
Further, the span of described screw flight helical pitch is 56 ± 0.5mm, and the span of the flight pitch on described screw rod is 28 ± 0.5mm.
The beneficial effect that the present invention obtains is: the extrusion system of extruder of the present invention is by strengthening screw rod and spiral shell
The diameter of cylinder, strengthen the R angle of the thread bush that described screw rod is arranged, improve the grinding efficiency of screw rod, make the extrusion system of extruder be applicable to process the coating mixing powder, and can complete mix that powder amount reaches the material of 30% extrude work.
Accompanying drawing explanation
Fig. 1 is the structural representation of the extrusion system of existing extruder;
Fig. 2 is the structural representation of the extrusion system of extruder of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described further.
As shown in Figure 1, the present embodiment provides a kind of extrusion system of extruder, comprise screw rod 1, barrel, hopper, head and mould (not shown), the diameter d of described screw rod 1 strengthens, internal diameter is constant, the diameter D of described barrel (not shown) is corresponding be increased to equal with the diameter d of described screw rod 1, as shown in Figure 2, the radius R at the R angle of the thread bush 11 that described screw rod 1 is arranged is increased to 10mm by 6mm, and lead S is constant.
Wherein, the diameter d of screw rod, is defined as in a standard
nominal diameter, refer to the maximum gauge of screw flight, namely with screw thread

Screw thread
helical pitchs refers to that on screw thread, any point is along same
helixcircle moved
axiallydistance.
single threadhelical pitch equal pitch (S=P), pitch P is on adjacent two tooth forms of screw thread
corresponding pointsbetween axial distance,
multi start threadhelical pitch equal
line numberbe multiplied by pitch (S=nP), line number n is the helix number of screw thread.In an embodiment of the present invention, the span of the lead S of described screw rod 1 is 56 ± 0.5mm, and the span of the flight pitch P on described screw rod 1 is 28 ± 0.5mm, and namely line number n is 2.
