Abstract
The utility model discloses a kind of pulsation exhaust plastic wood mixing extruder, comprise barrel and the loading hopper, discharging opening and fervent head and the exhaust outlet that are arranged on the barrel, in the barrel of described extruder loading hopper below is two-flight screw, barrel in the two-flight screw zone is provided with exhaust outlet, in the barrel in two-flight screw downstream is milling device, milling device is provided with a plurality of adjustable pin that is fixed on the barrel, in the barrel of milling device downstream is single-wormed screw, and single-wormed screw connects discharging opening and fervent head.It blendes together fusible plastics and string (as wood powder, peanut shell etc.) that can not fusion with a kind of new material mutually.Compared with prior art have characteristics such as equipment volume is little, feeding fast, be uniformly dispersed, mixing of materials is permeated, equipment investment is lacked.
Description
Technical field
The utility model relates to a kind of pulsation exhaust plastic wood mixing extruder.
Background technology
Extruder is the universal machine of plastic processing, as the various plastic tubes of extrusion molding, polybag, plastic sheet etc., its feature is to use single material, the form of its screw rod has single screw rod and twin-screw, and basic principle is that plastic processing is become a kind of melt, increases pressure and makes its even plasticizing, then by various mould moldings, its shortcoming is the material of two or more different molecular structures can not to be mixed mutually, and especially the material that heating can not be able to not be flowed mixes mutually
The utility model content
The utility model technical issues that need to address just are to overcome the defective of existing extruder, a kind of pulsation exhaust plastic wood mixing extruder is provided, and it blendes together fusible plastics and string (as wood powder, peanut shell etc.) that can not fusion with a kind of new material mutually.
For addressing the above problem, the utility model adopts following technical scheme:
A kind of pulsation exhaust of the utility model plastic wood mixing extruder, comprise barrel and the loading hopper, discharging opening and fervent head and the exhaust outlet that are arranged on the barrel, in the barrel of described extruder loading hopper below is two-flight screw, barrel in the two-flight screw zone is provided with exhaust outlet, in the barrel in two-flight screw downstream is milling device, milling device is provided with a plurality of adjustable pin that is fixed on the barrel, in the barrel of milling device downstream is single-wormed screw, and single-wormed screw connects discharging opening and fervent head.
Two-flight screw described in the utility model is a gradually changeable, and the depth of thread reduces downstream from the upstream.
Adjustable pin described in the utility model is 8-16.
Single extruder, although it is various informative, function is different, but can not solve the technical problem that fusible plastics and string (as wood powder, peanut shell etc.) that can not fusion is blended together mutually a kind of new material, the technical solution of the utility model is that the extruder that function is different is fit to live part of the present utility model, adopt cordwood method assembly unit, it is comprehensive that it is possessed.
The utility model is at first used the two-flight screw of gradual change, the plastics that mix and string compressed heat, air after will compressing by exhaust outlet and moisture are discharged barrel, this moment, plastics melted, variation compression ratio increase along with the gradual change screw rod, plastics and string further are compressed in one, this moment, plastics and string did not also fully mix, two kinds of materials after compression and the dehydration are delivered to the milling device the inside, milling device is fixed on the barrel a plurality of adjustable pins and two kinds of materials are stirred disperses, and then give before becoming the single-wormed screw mixing, up to discharging opening, be cut into bulk material by fervent head at last.
The beneficial effects of the utility model are:
The utility model compared with prior art has characteristics such as equipment volume is little, feeding fast, be uniformly dispersed, mixing of materials is permeated, equipment investment is lacked.Raw material uses waste or used plastics and broken string, but the same recycled for multiple times with plastics of the material of making because of string does not use glue to use plastics, so this material non-toxic is tasteless, belongs to environmental protection, green, type technology capable of circulation in synthetic.Its creativeness exists: single screw extrusion machine can't be finished the abundant mixing of plastics and string separately, double screw extruder involves great expense, the utility model is an assembly unit pulsation milling device on the basis of single screw rod, adjustable shear pin constitutes excellent dispersion milling effect, the utility model reasonable structural design, can eat up very coarse waste materials, thereby the material after having determined to synthesize has very low cost advantage, also use the product of this material that good economic benefits is arranged, utilize discarded object also must produce social benefit in a large number with regard to having determined.
The utility model blendes together various plastics with a kind of new material with fusible plastics and string (as wood powder, peanut shell etc.) that can not fusion after by extruder mutually---mould wood raw material.The material of the utility model production can be widely used in all spectra of synthetic plate, the synthetic sheet material of compression also has the good flame effect after having density height, intensity height, nonpoisonous and tasteless, waterproof and dampproof, ageing-resistant, sound-insulating and heat-insulating, acid-fast alkali-proof, insulation, adding assistant, is widely used in fields such as kitchen-toilet plate, decorative plate, building template, floor.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, a kind of pulsation exhaust of the utility model plastic wood mixing extruder, comprise barrel 1 and the loading hopper 2, discharging opening 3 and fervent head 4 and the exhaust outlet 5 that are arranged on the barrel, in the barrel of described extruder loading hopper below is two-flight screw 6, barrel in the two-flight screw zone is provided with exhaust outlet, in the barrel in two-flight screw downstream is milling device 7, milling device is provided with a plurality of adjustable pin 8 that is fixed on the barrel, in the barrel of milling device downstream is single-wormed screw 9, and single-wormed screw connects discharging opening and fervent head.
Two-flight screw described in the utility model is a gradually changeable, and the depth of thread reduces downstream from the upstream.
Adjustable pin described in the utility model is 8-16.
The utility model is not limited to above-mentioned preferred forms, and other any identical with the utility model or akin products that anyone draws under enlightenment of the present utility model all drop within the protection domain of the present utility model.
Claims (3)
