Abstract
The utility model discloses a serial single-screw extruder, comprising extruding screw rods and machine barrels. The extruding screw rods are arranged in the machine barrel, one end of the extruding screw rod is connected with a reducer casing, and the reducer casing is connected with a drive motor. The serial single-screw extruder is characterized in that: the machine barrel comprises a first machine barrel and a second machine barrel, the first machine barrel is accordingly provided with a first extruding screw rod, the second machine barrel is provided with a second extruding screw rod, and the first extruding screw rod and the second extruding screw rod are respectively connected with a reducer casing and the reducer casings are respectively connected with the drive motor. Besides, the delivery outlet of the first machine barrel is connected with the input port of the second machine barrel by pipelines, a feed inlet is positioned at the first machine barrel, and a discharge port is positioned at the second machine barrel. The serial single-screw extruder makes use of the extruder with two connected stages to gradually realize the plasticizing function in the plastic extruding process. Therefore, the structure of each screw rod is simplified, the length of each screw rod is shortened, and the maintenance for manufacturing is also convenient.
Description
Technical field
The utility model relates to a kind of screw plastic extruder, specifically a kind of tandem single screw extrusion machine.
Background technology
Plastic extruder is with the visual plant of plastic raw materials by the extrusion modling of heating.After plastic raw materials enters machine barrel from the charge door of machine barrel, under the effect of screw rod,, under the drive of screw rod, advance on the other hand, make various plastic products through corresponding auxiliary mould or equipment again to discharging opening on the one hand by the extruding back plasticizing of heating.In order to guarantee to extrude effect, often require plastics in extrusion process through preliminary plasticizing, a series of processes such as plasticizing, build-up pressure output fully, adopt the structure of traditional single screw rod to guarantee that the realization of these a series of processes just must be able to make the structure relative complex of screw rod, length is longer, the outlet section difficult control of temperature, this has brought sizable difficulty for design and manufacturing, makes troubles for maintenance and use, makes the quality of finished product be subjected to certain influence simultaneously.
Summary of the invention
The purpose of this utility model provides a kind of tandem single screw extrusion machine, by the extruder that second order links to each other the plasticizing function in the plastics extrusion process is realized by sublevel, thereby simplify the structure of every rank screw rod, shorten the length of every rank screw rod, bring great convenience for the maintenance of making.
Technical solution of the present utility model is:
A kind of tandem single screw extrusion machine, comprise extrusion screw rod, machine barrel, extrusion screw rod is installed in the machine barrel, one end of extrusion screw rod links to each other with reduction box, reduction box links to each other with drive motors, it is characterized in that machine barrel is made up of the first rank machine barrel and the second rank machine barrel, the first rank extrusion screw rod correspondingly is installed in the first rank machine barrel, the second rank extrusion screw rod is installed in the second rank machine barrel, the first rank extrusion screw rod, the second rank extrusion screw rod respectively with separately deceleration mutually case connect, reduction box separately all is connected with drive motors; The delivery outlet of the first rank machine barrel links to each other by the input port of pipeline with the second rank machine barrel; Charging aperture is positioned on the first rank machine barrel, and discharging opening is positioned on the second rank machine barrel.
The first above-mentioned rank extrusion screw rod is the extrusion screw rod that has divergence type screw channel and/or barrier type screw channel.The second rank extrusion screw rod is the extrusion screw rod that has coarse pitch, dark screw channel.Pressure control device has been installed on pipeline in addition.
The beneficial effects of the utility model:
1, the first rank extrusion screw rod can make raw material finish 60～80% plasticizing, realize basic fusion, the second rank extrusion screw rod can guarantee that raw material continues fusion and build-up pressure, bears small shearing force, effectively avoid the generation of superheating phenomenon, thereby fundamentally optimize whole extrusion.
2, by on the pipeline that connects the first rank extruder barrel and the second rank extruder barrel, the pressure detecting mouth being set, pressure to the first rank extrusion screw rod delivery outlet is sampled, utilize conventional control method can control the operating pressure of whole extruder easily, the output pressure fluctuation range is controlled in 0.5%.
3, output is big, the efficient height, and mixing ability is strong.
4, can reduce the fusion temperature of complete machine, have remarkable energy saving effect.
5, can use with the large-scale production matched with devices, can be widely used in fields such as film, tubing.
