Abstract
The utility model discloses a modular high-speed incongruous dual-screw extruder designed by forming the screw in a modularized way, with large length-diameter ratio, high rotational speed, and large production capacity of the screw. The utility model comprises machine barrels and screws arranged in the machine barrels, wherein, two screws with opposite thread directions are arranged in each machine barrel. The utility model is characterized in that each screw is formed by the combination of a plurality of screw blocks sheathed on the spindle.
Description
Technical field
The utility model relates to a kind of extruder, particularly a kind of modularization high speed counter rotation twin screw extruder.
Background technology
Counter rotation twin screw extruder is a kind of common plastic extruder.At present, owing to be subjected to the influence of processing technology, the draw ratio of screw rod is subjected to certain influence, and its draw ratio is all less than 25: 1.In order to solve the plasticizing problem of raw material, can only solve the plasticizing problem of raw material by the way of the lengthening time of staying of material in machine barrel, just must make the rotating speed decline of screw rod, generally all be lower than 100rpm and will prolong the time of staying, this just must bring and yield poorly, inefficient problem.
Summary of the invention
The purpose of this utility model is to form by screw rod being carried out modularization, designs the modularization high speed counter rotation twin screw extruder that a kind of screw slenderness ratio is big, rotating speed is high, output is high.
Technical solution of the present utility model is:
A kind of modularization high speed counter rotation twin screw extruder comprises machine barrel and is installed in screw rod in the machine barrel, and two screw rods that hand of spiral is opposite are installed in each machine barrel, it is characterized in that every screw rod is enclosed within on the mandrel by plurality of sections spiral shell piece to combine.
The beneficial effects of the utility model:
1, every long bolt is formed by connecting by plurality of sections spiral shell piece, has not only solved the processing problems of long bolt, and the length of long bolt can be unrestricted in theory, and this lays a good foundation for realize function distinguishing in same machine barrel.
2, the structure of every section spiral shell piece of composition long bolt can be identical, also can be different, and can realize any combination, thereby can in a machine barrel, solve all plasticizing problems, simplified complete machine structure.
3, output is improved greatly, the quality of item performance is better.The rotating speed of screw rod can be up to 200～500rpm, and draw ratio can reach 26～40: 1.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
A kind of modularization high speed counter rotation twin screw extruder comprises machine barrel 1 and the screw rod 2 that is installed in the machine barrel 1, and two screw rods 2 that hand of spiral is opposite are installed in each machine barrel 1, and every screw rod 2 is enclosed within on the mandrel 4 by plurality of sections spiral shell piece 3 and combines.On machine barrel 1, be provided with two exhaust outlets 5.The screw rod 2 of present embodiment is enclosed within on the mandrel 4 by three sections spiral shell pieces 3 and combines, the helicitic texture of every section spiral shell piece 3 can be identical, also can be different, can be respectively the helicitic texture, steep-pitch thread structure, dark pitch screw structure or its combination that have separating tank, can finish 60～80% plastics capacity near in first section spiral shell piece 3 of feed end, in second section, the 3rd section spiral shell piece 3, further finish plasticizing and making it suitably entering mould or the make-up machine from the exit after the cooling.The rotating speed of the screw rod 2 of present embodiment can be set between 200～500rpm, and draw ratio can be 26～40: choose arbitrarily between 1.The rotating speed of screw rod 2 can be made as 400rpm during concrete enforcement, and draw ratio can be made as 32: 1.
Claims (3)
