Abstract
Plastic extruders are important equipment for carrying out extrusion forming on plastic raw materials through heating. Screws of the plastic extruders are generally divided into feed segments, plasticization segments, compression segments, exhaust segments and extrusion segments, and materials pass through the segments in sequence and are finally extruded from the extrusion segments. With increase of actual production, the plastic extruders are required to have higher production capacity, so conveying barrels and screws of the plastic extruders are enlarged manyfold, however, overlong screws are adverse to uniformity of plastic melts and also can improve the complexity of the equipment and bring inconvenience to maintenance and use. The utility model provides a tandem type plastic extruder. The tandem type plastic extruder has the following beneficial effects that: the functions in the plastic extrusion forming process are achieved by stages through five stages of connected extruders, thus simplifying and shortening the length of the screw at each stage; and the single screw and single thread are adopted and the screw pitch and thread depth of the screw at each stage can be independently designed, therefore, the work efficiency of each stage is high, thus improving the overall production efficiency and product quality.
Description
Technical field
The utility model relates to knockdown plastic extruder, relates in particular to a kind of plastic extruder of star pattern.
Background technology
Plastic extruder is with the visual plant of plastic raw materials through the extrusion modling of heating.The screw rod of plastic extruder is divided into feed zone, fluxing zone, compression section, exhaust section and extruding zone usually, and material through above-mentioned each section, is extruded from extruding zone successively at last.Along with the increase of actual production, require plastic extruder that higher production capacity is arranged, this just makes all at double increases of feeding tube, screw rod of plastics machine; Screw rod is long; The uniformity that is unfavorable for plastic melt, the while also can increase the complexity of equipment, has brought inconvenience for maintenance and use.
The utility model content
To existing technical problem, the utility model provides a kind of in-line plastic extruder, comprises feed zone extruder, fluxing zone extruder, compression section extruder, exhaust section extruder and extruding zone extruder.Wherein, feed zone extruder, fluxing zone extruder, compression section extruder, exhaust section extruder are connected successively with the exhaust section extruder and are connected.Each rank extruder all adopts single screw rod, single thread structure.Feed zone extruder screw, compression section extruder screw, fluxing zone extruder screw, exhaust section extruder screw, exhaust section extruder screw flight pitch become greatly gradually, and the screw thread groove depth shoals gradually.
A kind of in-line plastic extruder that the utility model provides, the extruder that links to each other through five rank with the function in the extruded in plastic forming process through realizing stage by stage, thereby simplify the length of every rank screw rod, shorten the length of every rank screw rod.Since adopt single screw rod but screw thread, and can design pitch, the depth of thread of every rank screw rod separately, the high efficiency on every rank, extruding zone can be designed to coarse pitch, and shallow thread can prevent that also finished product from sticking on the screw rod.Needs according to reality can design 2 rank, and the series connection plastic extruder on 3 rank or 4 rank is to reduce cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, feed zone extruder, 2, the fluxing zone extruder, 3, the compression section extruder moulds, 4, the exhaust section extruder, 5, the extruding zone extruder
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the utility model, feed zone extruder 1, and fluxing zone extruder 2, the compression section extruder moulds 3, exhaust section extruder 4, extruding zone extruder 5.Wherein, feed zone extruder 1, fluxing zone extruder 2, compression section extruder 3, exhaust section extruder 4 and exhaust section extruder 5 are connected successively and are connected.Each rank extruder all adopts single screw rod, single thread structure.Feed zone extruder screw, compression section extruder screw, fluxing zone extruder screw, exhaust section extruder screw, exhaust section extruder screw flight pitch become greatly gradually, and the screw thread groove depth shoals gradually.The extruder that links to each other through five rank with the function in the extruded in plastic forming process through realizing stage by stage, thereby simplify the length of every rank screw rod, shorten the length of every rank screw rod.Since adopt single screw rod but screw thread, and can design pitch, the depth of thread of every rank screw rod separately, the high efficiency on every rank, extruding zone can be designed to coarse pitch, and shallow thread can prevent that also finished product from sticking on the screw rod.Needs according to reality can design 2 rank, and the series connection plastic extruder on 3 rank or 4 rank is to reduce cost.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
Claims (2)
