Description
Technical field
The utility model relates to a kind of ten planet screw extruders, belongs to plastics machinery field.
Background technology
PVC is polyvinyl chloride, it is the thermoplastic resin being polymerized under initator effect by vinyl chloride, it is a kind of macromolecular material that uses a chlorine atom to replace a hydrogen atom in polyethylene, it is for the manufacture of pipe, rod, plate, film, hollow product and various industrial or agricultural articles for use and commodity, processing for PVC, require extruder can extrusion plasticizing quality high, mixing uniform melt, and guarantee that melt residence time is short, can carry out effective exhaust, and nowadays general PVC is processed by single screw extrusion machine, single screw extrusion machine exists melt to be detained, therefore can cause the problem of burnt material.
Summary of the invention
The purpose of this utility model is to provide a kind of ten planet screw extruders.
Problem to be solved in the utility model is the defect that existing extruder processing PVC material exists melt to be detained.
For realizing the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of ten planet screw extruders of the utility model, comprise base, motor, reduction box, charging aperture, hopper, driving screw, machine barrel a, machine barrel b, die head, planetary-screw and bracing frame, described motor and reduction box are arranged on base, and motor rotary shaft is connected with reduction box; Machine barrel a is arranged on reduction box body by flange, has a charging aperture on machine barrel a, and hopper is arranged on charging aperture, and machine barrel b and machine barrel a are threaded connection and are installed together, and machine barrel b inwall is provided with helicla flute, and die head is arranged on the afterbody of machine barrel b; Driving screw is arranged in machine barrel a and machine barrel b, and driving screw shank is connected with reduction box, and the thread segment of latter half of driving screw is involute profile, and spiral is multiple thread; Planetary-screw has nine, and the thread segment of planetary-screw is involute profile, and spiral is multiple thread, and planetary-screw is evenly distributed between driving screw and machine barrel b, and planetary-screw meshes with machine barrel b and driving screw simultaneously; Machine barrel b is fixed on base by bracing frame, and machine barrel a and machine barrel b outer wall are all provided with electric heater unit.
The utility model has the advantages that: the latter half of engagement of planetary-screw and driving screw, by planetary-screw and driving screw mixing, roll and can make PVC plasticizing more even, and can guarantee that melt residence time is short, therefore Jiao's material that solves the melt delay of single screw extrusion machine and cause, planetary extruder also has the feature of improving the quality of products, reducing energy consumption, improve production environment.
